Patient with newly diagnosed type 2 diabetes? Remember these steps
Nearly 40 antihyperglycemic agents have been approved by the US Food and Drug Administration (FDA) since the approval of human insulin in 1982.1 In addition, existing antihyperglycemic medications are constantly gaining FDA approval for new indications for common type 2 diabetes (T2D) comorbidities. For example, in addition to their glycemic benefits, the sodium-glucose cotransporter-2 (SGLT2) inhibitors have been approved for use in patients with T2D and established atherosclerotic cardiovascular disease (ASCVD) to reduce the risk for major adverse cardiovascular events (MACE; canagliflozin), risk for hospitalization for heart failure (dapagliflozin), and cardiovascular death (empagliflozin).2-4
The plethora of new agents and new data for existing agents, coupled with the annual release of guidelines from the American Diabetes Association (ADA) and practice recommendations from several other professional organizations,5-7 make it challenging for family physicians to stay current and provide the most up-to-date, evidence-based care. In this article, we provide advice on how to approach the screening, diagnosis, and evaluation of T2D, and on how to manage newly diagnosed T2D.
Screening, Dx, and evaluation: A quick review
Screening
Screening recommendations vary among professional organizations (TABLE 15,6,8). The US Preventive Services Task Force (USPSTF) recommends screening adults ages 35 to 70 years who are overweight or obese. Clinicians also can consider screening patients with a higher risk for diabetes.5 The ADA suggests screening all adults starting at 35 years, regardless of risk factors.8 Asymptomatic adults of any age with overweight or obesity and 1 or more risk factors should be screened.8
Making the diagnosis
The initial diagnosis of diabetes can be made by a fasting plasma glucose level ≥ 126 mg/dL (7.0 mmol/L); a 2-hour plasma glucose level ≥ 200 mg/dL (11.0 mmol/L) following an oral glucose tolerance test; or an A1C level ≥ 6.5%. Prioritize lab-drawn A1C measurements over point-of-care tests to diagnose T2D. In patients with classic symptoms of hyperglycemia, a random plasma glucose level ≥ 200 mg/dL (11.0 mmol/L) is also diagnostic. Generally, these tests are considered equally appropriate in screening for diabetes and may be used to detect prediabetes. In the absence of clear symptoms of hyperglycemia, the diagnosis of diabetes requires 2 abnormal screening test results, either via 1 blood sample (such as an abnormal A1C and glucose) or 2 separate blood samples of the same test. Further evaluation is advised if there is discordance between the 2 samples.8
Extended evaluations
Patients with newly diagnosed T2D require a thorough evaluation for comorbidities and complications of diabetes. Refer patients to an ophthalmologist for a dilated eye examination, with subsequent exams occurring every 1 to 2 years.6,9 Additional referrals for diabetes education, family planning for women of reproductive age, and dental, social, or mental health services may be clinically appropriate.9
Setting goals for glycemic control
Glycemic control is commonly monitored by the A1C level and by blood glucose monitoring either through traditional point-of-care glucometers or continuous glucose monitors (CGMs).10 Generally, CGMs provide more glycemic data than traditional glucometers and may cue patients to choose healthier dietary options and engage in physical exercise.11 Patients with T2D who use CGMs exhibit lower A1Cs, greater time in glycemic range, and reduced hypoglycemic episodes.11 Generally, CGMs are reserved for patients with type 1 diabetes and patients with T2D who use multiple daily injections, subcutaneous insulin infusions, or basal insulin only.12 Most professional organizations recommend that clinicians consider patient-specific factors to set individualized glycemic goals.6,10,13,14 For example, more stringent glycemic goals could be pursued for patients with longer life expectancy, shorter disease duration, absence of complications (eg, nephropathy, neuropathy, or cardiovascular disease), fewer comorbid conditions, lower hypoglycemia risk, or higher cognitive function.6
More specific A1C goals vary by professional organization. For nonpregnant adults, the ADA recommends an A1C goal of < 7% and a preprandial blood glucose level of 80 to 130 mg/dL (4.4-7.2 mmol/L).10 However, a lower A1C goal may be appropriate if it can be attained safely without causing hypoglycemia or other adverse effects.10 The AACE suggests an A1C goal of ≤ 6.5% and a fasting blood glucose level of < 110 mg/dL when it can be achieved safely.6 More stringent A1C goals may reduce long-term micro- and macrovascular complications—especially in patients with newly diagnosed T2D.10 While older studies such as the ACCORD trial found increased mortality in groups with more stringent glycemic targets, they did not include newer agents (SGLT2 inhibitors or glucagon-like peptide-1 [GLP-1] receptor agonists) that reduce cardiovascular events by mechanisms outside their glycemic-lowering effect. With these newer agents, more aggressive A1C goals can be targeted safely in select patients, particularly those with long life expectancy.10 Both the ADA and AACE recommend a less stringent A1C goal of 7% to 8% for patients with limited life expectancy or risks (eg, a history of hypoglycemia) that outweigh expected benefits.6,10
Continue to: Lifestyle modifications
Lifestyle modifications: As important as medication
Nutrition
The energy-dense Western diet, combined with sedentary behavior, are thought to be a primary cause of T2D.15 Therefore, include lifestyle modifications in the initial management of newly diagnosed T2D. Diets that replace carbohydrates with saturated and trans fats are related to increased mortality in patients with T2D.16 Increased consumption of vegetables, fruits, legumes, nuts, fish, cereal, and oils reduces concentrations of saturated and trans fats and increases dietary intake of monounsaturated fatty acids, fiber, antioxidants, and polyphenols.17
Increasing the intake of fiber, an undigestible carbohydrate, offers numerous benefits in T2D management. High-fiber diets can help regulate blood sugar and lipid levels, increase satiety, reduce inflammation, aid in weight management, and reduce premature mortality.18 Insoluble fiber, found in foods such as whole wheat flour, nuts, and cauliflower, helps food pass more quickly through the stomach and intestines and adds bulk to stool. Soluble fiber, found in foods such as chickpeas, lentils, and Brussels sprouts, absorbs water and forms a gel-like substance that protects nutrients from digestive enzymes and slows down digestion. The result is a more gradual rise in postprandial glucose levels and improved insulin sensitivity.19 Dietary fiber may produce short-chain fatty acids which in turn activate incretin secretion and stimulate a glucose-dependent release of insulin from the pancreas.20
Simple dietary substitutions, such as whole grains and legumes for white rice, can reduce fasting blood glucose and A1C levels.21 In a randomized controlled trial (RCT), increasing whole grain oat intake improved measures of glycemic control, reducing A1C by 1% at 1-year follow-up.19 Encourage patients with T2D to increase consumption of high-fiber foods and replace animal fats and refined grains with vegetable fats (eg, nuts, avocados, olives). Nutritional therapies should be individualized, taking into account personal preferences and cultural customs.22 Nutritional habits may be based on race/ethnicity, religion/spirituality, or even the city in which an individual resides. Nutrition recommendations should account for these differences as well as access to healthy foods. For instance, ethnic groups whose dietary patterns include tortillas could be counseled to choose high-fiber options such as corn instead of flour tortillas and to incorporate vegetables in place of high-fat foods. Additionally, ethnic groups who favor using animal fats in foods such as greens could be advised on ways to add flavor to vegetables without adding saturated fats. Taking this approach may lessen barriers to change and increase ability to make dietary modifications.23
Exercise
Encourage all patients with T2D to exercise regularly. The atherosclerotic plaques found in patients with T2D have increased inflammatory properties and result in worse cardiovascular outcomes compared with plaques in individuals without T2D.24 Regular exercise reduces levels of pro-inflammatory markers—C-reactive protein, interleukin (IL)-6, and tumor necrosis factor alpha—and increases levels of anti-inflammatory markers (IL-4 and IL-10).24 Regular exercise can improve body composition, physical fitness, lipid and glucose metabolism, and insulin sensitivity.25,26
A meta-analysis of RCTs demonstrated that structured exercise > 150 minutes per week resulted in A1C reductions of 0.89%,27 which is comparable to the effect of many oral antihyperglycemic medications.26 The Health Benefits of Aerobic and Resistance Training in individuals with T2D (HART-D) and Diabetes Aerobic and Resistance Exercise (DARE) studies demonstrated that combining endurance and resistance training was superior for improving glycemic control, cardiorespiratory fitness, and body composition, than using either type of training alone.25 Both the American College of Sports Medicine (ACSM) and the ADA recommend that adults engage in at least 150 total minutes of moderate-intensity aerobic activity per week and resistance training 2 to 3 times weekly.26 ACSM defines moderate-intensity exercise as 65% to 75% of maximal heart rate, a rating of perceived exertion of 3 to 4, or a step rate of 100 steps per minute.28
Continue to: Because of their longitudinal relationships...
Because of their longitudinal relationships with patients, family physicians are in an optimal position to assess a patient’s physical capacity level and provide individualized counseling. Several systematic reviews have demonstrated that counseling on exercise increases patients’ participation in physical activity.29 Encourage your patients with T2D to exercise regularly, considering each individual’s ability to engage in physical activity.
Weight loss
Include weight management in the initial treatment of patients with newly diagnosed T2D. Weight loss decreases hepatic glucose production and increases peripheral insulin sensitivity and insulin secretion.30 Moderate decreases in weight (5%-10%) can reduce complications related to diabetes, and sustained significant weight loss (> 10%) can potentially cause T2D remission (A1C < 6.5% after stopping diabetes medications).31,32
Diabetes self-management education supports patients by giving them tools for making and maintaining lifestyle changes. Understanding individual barriers to change and addressing these during motivational interviews is important. Through a qualitative interview study, participants in a diabetes self-management program revealed 4 factors that motivated them to maintain lifestyle changes: support from others, experiencing the impact of the changes they made, fear of T2D complications, and forming new habits.33 Family physicians are key in helping patients acquire knowledge and support to make the lifestyle modifications needed to manage newly diagnosed T2D.
Individualized pharmacotherapy considerations
For decades, the initial pharmacotherapeutic regimen for patients with newly diagnosed T2D considered the patient’s baseline A1C as a major driver for therapy. Metformin has been the mainstay in T2D treatment due to its clinical efficacy, minimal risk for hypoglycemia, and low cost. Regardless of the regimen, pharmacotherapy should be initiated at the time of T2D diagnosis in conjunction with the aforementioned lifestyle modifications.34
When selecting pharmacotherapy, practice guidelines recommend considering the efficacy and adverse effects of medications, patient-specific comorbidities, adherence, cost, and a patient’s lifestyle factors.34 Drug classes with pertinent information are listed in TABLE 2.34-54 After starting medication, monitor the A1C level every 3 months to determine whether therapy should be intensified. Patients should have their labs drawn ahead of the quarterly visit, or point-of-care measurements may be used to facilitate in-person patient–provider discussions.
Continue to: Consider patient-specific factors when starting pharmacotherapy
Consider patient-specific factors when starting pharmacotherapy
ASCVD. Regardless of baseline glycemic control, offer patients who have ASCVD, or who are at high risk for it, an SGLT2 inhibitor (canagliflozin, dapagliflozin, or empagliflozin) or a long-acting GLP-1 receptor agonist (dulaglutide, liraglutide, or semaglutide).34,35 SGLT2 inhibitors reduced the risk for MACE by 11% in patients with established ASCVD.55 They also reduced a composite outcome of cardiovascular death or hospitalization for heart failure by 23% in patients with or without ASCVD or heart failure at baseline.55 GLP-1 receptor agonists offer a similar reduction in MACE to SGLT2 inhibitors, but they do not have significant effects in heart failure.56 Thiazolidinediones (TZDs), saxagliptin, and alogliptin should be avoided in patients with heart failure.57 TZDs may reduce the risk for recurrent stroke in patients with T2D.58
Chronic kidney disease (CKD). As with ASCVD, prioritize SGLT2 inhibitors and GLP-1 receptor agonists in patients with CKD. While both classes reduced the risk for progression of kidney disease such as macroalbuminuria, SGLT2 inhibitors offer additional benefits in their reduction of the worsening of estimated glomerular filtration rate, end-stage kidney disease, and renal death.56
Obesity. Consider the effect of each drug class on weight when making initial treatment choices, taking special care to minimize weight gain and potentially promote weight loss.34 The ADA prefers GLP-1 receptor agonists, but also suggests SGLT2 inhibitors in these patients. While all GLP-1 receptor agonists have an impact on weight, weekly subcutaneous semaglutide offers the most pronounced weight loss of 2 to 7 kg over 56 weeks.59 SGLT2 inhibitors promote sustainable weight loss to a lesser degree, contributing to an average loss of 3 kg at 2 years.60 Weight gain is common in patients taking sulfonylureas (2.01-2.3 kg)31 and insulin (3-9 kg weight gain in the first year)61 and should be avoided in patients with T2D and obesity.34
Hypoglycemia risk. In addition to counseling patients on hypoglycemia management and prescribing glucagon rescue kits, offer medications with no or very low risk for hypoglycemia (eg, GLP-1 receptor agonists, SGLT2 inhibitors, dipeptidyl peptidase-4 inhibitors, and TZDs). Generally, avoid insulin and sulfonylureas in patients in whom hypoglycemia is a major concern (eg, older adults, individuals with labile blood glucose levels).34 Patients with reduced renal function are at higher risk for hypoglycemia with insulin or sulfonylureas due to reduced drug clearance. However, insulin is often the only treatment for patients with advanced renal disease. Pay close attention to insulin dosing in patients with advanced renal disease, which may necessitate lower doses and smaller dose adjustments due to this risk.
Social determinants of health. Medication access and cost is a major burden in T2D management and should be considered for every patient. Compared with the period of 2005 to 2007, the annual cost of diabetes medications for an individual in 2015 to 2017 increased by 147%, rising from $1106 to $2727 per year.62 This increase is driven by the cost of insulin and newer medications without generic options.62 Identify local resources in your community, such as patient assistance programs and pharmacies with reduced-price generic prescription programs, which may be useful for patients who are underinsured or uninsured.
Continue to: Even if cost weren't an issue...
Even if cost weren’t an issue, many medications such as insulin and GLP-1 receptor agonists should be kept refrigerated and are only stable at room temperature for a limited time. Medications that are stable at room temperature should be prioritized in patients with limited or inconsistent access to refrigeration or unstable housing who may find it difficult to store their medications appropriately.
Do not delay insulin initiation in patients with high baseline A1C
Whenever possible, a GLP-1 receptor agonist is the preferred injectable medication to insulin. Starting insulin introduces numerous risks, including hypoglycemia, weight gain, and stigma. However, in the patient with newly diagnosed T2D, choose basal insulin when the baseline hyperglycemia is severe,34 as indicated by:
- blood glucose > 300 mg/dL (16.7 mmol/L),
- A1C > 10% (86 mmol/mol),
- symptoms of hyperglycemia (polyuria or polydipsia), or
- evidence of catabolism (weight loss, hypertriglyceridemia, ketosis).
Basal insulin analogs are preferred over NPH given their reduced variability, dosing, and hypoglycemic risk.35 Mixed insulins may be used if a patient is unable to afford an insulin analog, which can be quite costly. However, extensive counseling on dosing and management of hypoglycemia is crucial to patient safety with these agents. The ADA recommends initiating 0.1 to 0.2 units/kg of basal insulin daily or 10 units daily.34 The AACE follows this recommendation for patients with baseline A1C < 8%, but it proposes a more aggressive initiation of 0.2 to 0.3 units/kg/d for patients with baseline A1C > 8%.35 Titrate the dose by 2 units every 3 days to reach the target fasting blood glucose level. As hyperglycemia resolves, simplify the regimen and transition to noninsulin options per the previously discussed considerations.
It’s not just about glycemic control
In addition to the direct effects of hyperglycemia, a T2D diagnosis introduces an increased risk for ASCVD, a reduced ability to fight infection, and heightened risk for depression. Order a lipid panel at the time of T2D diagnosis and initiate lipid management as needed (TABLE 335,63,64). Both the ADA and the American Heart Association recommend starting a moderate-intensity statin as primary prevention for all patients with T2D between 40 and 75 years of age regardless of the 10-year ASCVD risk.63 The AACE uses specific lipid targets and recommends moderate- to high-intensity statin therapy for patients with T2D.35 All recommendations by professional organizations list high-intensity statins for patients with established ASCVD.
It is also vital to recommend that patients with newly diagnosed T2D remain up to date on all indicated vaccinations. They should promptly receive the hepatitis B and pneumococcal vaccines if they have not already done so for a previous indication. COVID-19 and annual influenza vaccines also should be prioritized for these patients.65
Finally, patients with diabetes are twice as likely to develop depression than patients without diabetes.66 Individuals with T2D and depression exhibit poorer medication adherence, lifestyle choices, and glycemic control.66 Screen for and treat these issues in all patients with T2D across the course of the disease.
Overall, work closely with patients to support them in managing their new diagnosis with evidence-based pharmacologic and nonpharmacologic approaches. The importance of lifestyle changes including high-fiber diets, regular exercise, and weight loss should not be overlooked. Do not delay starting pharmacotherapy after diagnosing T2D and consider medication-specific and patient-specific factors to individualize therapy, improve adherence, and prevent complications.

Nearly 40 antihyperglycemic agents have been approved by the US Food and Drug Administration (FDA) since the approval of human insulin in 1982.1 In addition, existing antihyperglycemic medications are constantly gaining FDA approval for new indications for common type 2 diabetes (T2D) comorbidities. For example, in addition to their glycemic benefits, the sodium-glucose cotransporter-2 (SGLT2) inhibitors have been approved for use in patients with T2D and established atherosclerotic cardiovascular disease (ASCVD) to reduce the risk for major adverse cardiovascular events (MACE; canagliflozin), risk for hospitalization for heart failure (dapagliflozin), and cardiovascular death (empagliflozin).2-4
The plethora of new agents and new data for existing agents, coupled with the annual release of guidelines from the American Diabetes Association (ADA) and practice recommendations from several other professional organizations,5-7 make it challenging for family physicians to stay current and provide the most up-to-date, evidence-based care. In this article, we provide advice on how to approach the screening, diagnosis, and evaluation of T2D, and on how to manage newly diagnosed T2D.
Screening, Dx, and evaluation: A quick review
Screening
Screening recommendations vary among professional organizations (TABLE 15,6,8). The US Preventive Services Task Force (USPSTF) recommends screening adults ages 35 to 70 years who are overweight or obese. Clinicians also can consider screening patients with a higher risk for diabetes.5 The ADA suggests screening all adults starting at 35 years, regardless of risk factors.8 Asymptomatic adults of any age with overweight or obesity and 1 or more risk factors should be screened.8
Making the diagnosis
The initial diagnosis of diabetes can be made by a fasting plasma glucose level ≥ 126 mg/dL (7.0 mmol/L); a 2-hour plasma glucose level ≥ 200 mg/dL (11.0 mmol/L) following an oral glucose tolerance test; or an A1C level ≥ 6.5%. Prioritize lab-drawn A1C measurements over point-of-care tests to diagnose T2D. In patients with classic symptoms of hyperglycemia, a random plasma glucose level ≥ 200 mg/dL (11.0 mmol/L) is also diagnostic. Generally, these tests are considered equally appropriate in screening for diabetes and may be used to detect prediabetes. In the absence of clear symptoms of hyperglycemia, the diagnosis of diabetes requires 2 abnormal screening test results, either via 1 blood sample (such as an abnormal A1C and glucose) or 2 separate blood samples of the same test. Further evaluation is advised if there is discordance between the 2 samples.8
Extended evaluations
Patients with newly diagnosed T2D require a thorough evaluation for comorbidities and complications of diabetes. Refer patients to an ophthalmologist for a dilated eye examination, with subsequent exams occurring every 1 to 2 years.6,9 Additional referrals for diabetes education, family planning for women of reproductive age, and dental, social, or mental health services may be clinically appropriate.9
Setting goals for glycemic control
Glycemic control is commonly monitored by the A1C level and by blood glucose monitoring either through traditional point-of-care glucometers or continuous glucose monitors (CGMs).10 Generally, CGMs provide more glycemic data than traditional glucometers and may cue patients to choose healthier dietary options and engage in physical exercise.11 Patients with T2D who use CGMs exhibit lower A1Cs, greater time in glycemic range, and reduced hypoglycemic episodes.11 Generally, CGMs are reserved for patients with type 1 diabetes and patients with T2D who use multiple daily injections, subcutaneous insulin infusions, or basal insulin only.12 Most professional organizations recommend that clinicians consider patient-specific factors to set individualized glycemic goals.6,10,13,14 For example, more stringent glycemic goals could be pursued for patients with longer life expectancy, shorter disease duration, absence of complications (eg, nephropathy, neuropathy, or cardiovascular disease), fewer comorbid conditions, lower hypoglycemia risk, or higher cognitive function.6
More specific A1C goals vary by professional organization. For nonpregnant adults, the ADA recommends an A1C goal of < 7% and a preprandial blood glucose level of 80 to 130 mg/dL (4.4-7.2 mmol/L).10 However, a lower A1C goal may be appropriate if it can be attained safely without causing hypoglycemia or other adverse effects.10 The AACE suggests an A1C goal of ≤ 6.5% and a fasting blood glucose level of < 110 mg/dL when it can be achieved safely.6 More stringent A1C goals may reduce long-term micro- and macrovascular complications—especially in patients with newly diagnosed T2D.10 While older studies such as the ACCORD trial found increased mortality in groups with more stringent glycemic targets, they did not include newer agents (SGLT2 inhibitors or glucagon-like peptide-1 [GLP-1] receptor agonists) that reduce cardiovascular events by mechanisms outside their glycemic-lowering effect. With these newer agents, more aggressive A1C goals can be targeted safely in select patients, particularly those with long life expectancy.10 Both the ADA and AACE recommend a less stringent A1C goal of 7% to 8% for patients with limited life expectancy or risks (eg, a history of hypoglycemia) that outweigh expected benefits.6,10
Continue to: Lifestyle modifications
Lifestyle modifications: As important as medication
Nutrition
The energy-dense Western diet, combined with sedentary behavior, are thought to be a primary cause of T2D.15 Therefore, include lifestyle modifications in the initial management of newly diagnosed T2D. Diets that replace carbohydrates with saturated and trans fats are related to increased mortality in patients with T2D.16 Increased consumption of vegetables, fruits, legumes, nuts, fish, cereal, and oils reduces concentrations of saturated and trans fats and increases dietary intake of monounsaturated fatty acids, fiber, antioxidants, and polyphenols.17
Increasing the intake of fiber, an undigestible carbohydrate, offers numerous benefits in T2D management. High-fiber diets can help regulate blood sugar and lipid levels, increase satiety, reduce inflammation, aid in weight management, and reduce premature mortality.18 Insoluble fiber, found in foods such as whole wheat flour, nuts, and cauliflower, helps food pass more quickly through the stomach and intestines and adds bulk to stool. Soluble fiber, found in foods such as chickpeas, lentils, and Brussels sprouts, absorbs water and forms a gel-like substance that protects nutrients from digestive enzymes and slows down digestion. The result is a more gradual rise in postprandial glucose levels and improved insulin sensitivity.19 Dietary fiber may produce short-chain fatty acids which in turn activate incretin secretion and stimulate a glucose-dependent release of insulin from the pancreas.20
Simple dietary substitutions, such as whole grains and legumes for white rice, can reduce fasting blood glucose and A1C levels.21 In a randomized controlled trial (RCT), increasing whole grain oat intake improved measures of glycemic control, reducing A1C by 1% at 1-year follow-up.19 Encourage patients with T2D to increase consumption of high-fiber foods and replace animal fats and refined grains with vegetable fats (eg, nuts, avocados, olives). Nutritional therapies should be individualized, taking into account personal preferences and cultural customs.22 Nutritional habits may be based on race/ethnicity, religion/spirituality, or even the city in which an individual resides. Nutrition recommendations should account for these differences as well as access to healthy foods. For instance, ethnic groups whose dietary patterns include tortillas could be counseled to choose high-fiber options such as corn instead of flour tortillas and to incorporate vegetables in place of high-fat foods. Additionally, ethnic groups who favor using animal fats in foods such as greens could be advised on ways to add flavor to vegetables without adding saturated fats. Taking this approach may lessen barriers to change and increase ability to make dietary modifications.23
Exercise
Encourage all patients with T2D to exercise regularly. The atherosclerotic plaques found in patients with T2D have increased inflammatory properties and result in worse cardiovascular outcomes compared with plaques in individuals without T2D.24 Regular exercise reduces levels of pro-inflammatory markers—C-reactive protein, interleukin (IL)-6, and tumor necrosis factor alpha—and increases levels of anti-inflammatory markers (IL-4 and IL-10).24 Regular exercise can improve body composition, physical fitness, lipid and glucose metabolism, and insulin sensitivity.25,26
A meta-analysis of RCTs demonstrated that structured exercise > 150 minutes per week resulted in A1C reductions of 0.89%,27 which is comparable to the effect of many oral antihyperglycemic medications.26 The Health Benefits of Aerobic and Resistance Training in individuals with T2D (HART-D) and Diabetes Aerobic and Resistance Exercise (DARE) studies demonstrated that combining endurance and resistance training was superior for improving glycemic control, cardiorespiratory fitness, and body composition, than using either type of training alone.25 Both the American College of Sports Medicine (ACSM) and the ADA recommend that adults engage in at least 150 total minutes of moderate-intensity aerobic activity per week and resistance training 2 to 3 times weekly.26 ACSM defines moderate-intensity exercise as 65% to 75% of maximal heart rate, a rating of perceived exertion of 3 to 4, or a step rate of 100 steps per minute.28
Continue to: Because of their longitudinal relationships...
Because of their longitudinal relationships with patients, family physicians are in an optimal position to assess a patient’s physical capacity level and provide individualized counseling. Several systematic reviews have demonstrated that counseling on exercise increases patients’ participation in physical activity.29 Encourage your patients with T2D to exercise regularly, considering each individual’s ability to engage in physical activity.
Weight loss
Include weight management in the initial treatment of patients with newly diagnosed T2D. Weight loss decreases hepatic glucose production and increases peripheral insulin sensitivity and insulin secretion.30 Moderate decreases in weight (5%-10%) can reduce complications related to diabetes, and sustained significant weight loss (> 10%) can potentially cause T2D remission (A1C < 6.5% after stopping diabetes medications).31,32
Diabetes self-management education supports patients by giving them tools for making and maintaining lifestyle changes. Understanding individual barriers to change and addressing these during motivational interviews is important. Through a qualitative interview study, participants in a diabetes self-management program revealed 4 factors that motivated them to maintain lifestyle changes: support from others, experiencing the impact of the changes they made, fear of T2D complications, and forming new habits.33 Family physicians are key in helping patients acquire knowledge and support to make the lifestyle modifications needed to manage newly diagnosed T2D.
Individualized pharmacotherapy considerations
For decades, the initial pharmacotherapeutic regimen for patients with newly diagnosed T2D considered the patient’s baseline A1C as a major driver for therapy. Metformin has been the mainstay in T2D treatment due to its clinical efficacy, minimal risk for hypoglycemia, and low cost. Regardless of the regimen, pharmacotherapy should be initiated at the time of T2D diagnosis in conjunction with the aforementioned lifestyle modifications.34
When selecting pharmacotherapy, practice guidelines recommend considering the efficacy and adverse effects of medications, patient-specific comorbidities, adherence, cost, and a patient’s lifestyle factors.34 Drug classes with pertinent information are listed in TABLE 2.34-54 After starting medication, monitor the A1C level every 3 months to determine whether therapy should be intensified. Patients should have their labs drawn ahead of the quarterly visit, or point-of-care measurements may be used to facilitate in-person patient–provider discussions.
Continue to: Consider patient-specific factors when starting pharmacotherapy
Consider patient-specific factors when starting pharmacotherapy
ASCVD. Regardless of baseline glycemic control, offer patients who have ASCVD, or who are at high risk for it, an SGLT2 inhibitor (canagliflozin, dapagliflozin, or empagliflozin) or a long-acting GLP-1 receptor agonist (dulaglutide, liraglutide, or semaglutide).34,35 SGLT2 inhibitors reduced the risk for MACE by 11% in patients with established ASCVD.55 They also reduced a composite outcome of cardiovascular death or hospitalization for heart failure by 23% in patients with or without ASCVD or heart failure at baseline.55 GLP-1 receptor agonists offer a similar reduction in MACE to SGLT2 inhibitors, but they do not have significant effects in heart failure.56 Thiazolidinediones (TZDs), saxagliptin, and alogliptin should be avoided in patients with heart failure.57 TZDs may reduce the risk for recurrent stroke in patients with T2D.58
Chronic kidney disease (CKD). As with ASCVD, prioritize SGLT2 inhibitors and GLP-1 receptor agonists in patients with CKD. While both classes reduced the risk for progression of kidney disease such as macroalbuminuria, SGLT2 inhibitors offer additional benefits in their reduction of the worsening of estimated glomerular filtration rate, end-stage kidney disease, and renal death.56
Obesity. Consider the effect of each drug class on weight when making initial treatment choices, taking special care to minimize weight gain and potentially promote weight loss.34 The ADA prefers GLP-1 receptor agonists, but also suggests SGLT2 inhibitors in these patients. While all GLP-1 receptor agonists have an impact on weight, weekly subcutaneous semaglutide offers the most pronounced weight loss of 2 to 7 kg over 56 weeks.59 SGLT2 inhibitors promote sustainable weight loss to a lesser degree, contributing to an average loss of 3 kg at 2 years.60 Weight gain is common in patients taking sulfonylureas (2.01-2.3 kg)31 and insulin (3-9 kg weight gain in the first year)61 and should be avoided in patients with T2D and obesity.34
Hypoglycemia risk. In addition to counseling patients on hypoglycemia management and prescribing glucagon rescue kits, offer medications with no or very low risk for hypoglycemia (eg, GLP-1 receptor agonists, SGLT2 inhibitors, dipeptidyl peptidase-4 inhibitors, and TZDs). Generally, avoid insulin and sulfonylureas in patients in whom hypoglycemia is a major concern (eg, older adults, individuals with labile blood glucose levels).34 Patients with reduced renal function are at higher risk for hypoglycemia with insulin or sulfonylureas due to reduced drug clearance. However, insulin is often the only treatment for patients with advanced renal disease. Pay close attention to insulin dosing in patients with advanced renal disease, which may necessitate lower doses and smaller dose adjustments due to this risk.
Social determinants of health. Medication access and cost is a major burden in T2D management and should be considered for every patient. Compared with the period of 2005 to 2007, the annual cost of diabetes medications for an individual in 2015 to 2017 increased by 147%, rising from $1106 to $2727 per year.62 This increase is driven by the cost of insulin and newer medications without generic options.62 Identify local resources in your community, such as patient assistance programs and pharmacies with reduced-price generic prescription programs, which may be useful for patients who are underinsured or uninsured.
Continue to: Even if cost weren't an issue...
Even if cost weren’t an issue, many medications such as insulin and GLP-1 receptor agonists should be kept refrigerated and are only stable at room temperature for a limited time. Medications that are stable at room temperature should be prioritized in patients with limited or inconsistent access to refrigeration or unstable housing who may find it difficult to store their medications appropriately.
Do not delay insulin initiation in patients with high baseline A1C
Whenever possible, a GLP-1 receptor agonist is the preferred injectable medication to insulin. Starting insulin introduces numerous risks, including hypoglycemia, weight gain, and stigma. However, in the patient with newly diagnosed T2D, choose basal insulin when the baseline hyperglycemia is severe,34 as indicated by:
- blood glucose > 300 mg/dL (16.7 mmol/L),
- A1C > 10% (86 mmol/mol),
- symptoms of hyperglycemia (polyuria or polydipsia), or
- evidence of catabolism (weight loss, hypertriglyceridemia, ketosis).
Basal insulin analogs are preferred over NPH given their reduced variability, dosing, and hypoglycemic risk.35 Mixed insulins may be used if a patient is unable to afford an insulin analog, which can be quite costly. However, extensive counseling on dosing and management of hypoglycemia is crucial to patient safety with these agents. The ADA recommends initiating 0.1 to 0.2 units/kg of basal insulin daily or 10 units daily.34 The AACE follows this recommendation for patients with baseline A1C < 8%, but it proposes a more aggressive initiation of 0.2 to 0.3 units/kg/d for patients with baseline A1C > 8%.35 Titrate the dose by 2 units every 3 days to reach the target fasting blood glucose level. As hyperglycemia resolves, simplify the regimen and transition to noninsulin options per the previously discussed considerations.
It’s not just about glycemic control
In addition to the direct effects of hyperglycemia, a T2D diagnosis introduces an increased risk for ASCVD, a reduced ability to fight infection, and heightened risk for depression. Order a lipid panel at the time of T2D diagnosis and initiate lipid management as needed (TABLE 335,63,64). Both the ADA and the American Heart Association recommend starting a moderate-intensity statin as primary prevention for all patients with T2D between 40 and 75 years of age regardless of the 10-year ASCVD risk.63 The AACE uses specific lipid targets and recommends moderate- to high-intensity statin therapy for patients with T2D.35 All recommendations by professional organizations list high-intensity statins for patients with established ASCVD.
It is also vital to recommend that patients with newly diagnosed T2D remain up to date on all indicated vaccinations. They should promptly receive the hepatitis B and pneumococcal vaccines if they have not already done so for a previous indication. COVID-19 and annual influenza vaccines also should be prioritized for these patients.65
Finally, patients with diabetes are twice as likely to develop depression than patients without diabetes.66 Individuals with T2D and depression exhibit poorer medication adherence, lifestyle choices, and glycemic control.66 Screen for and treat these issues in all patients with T2D across the course of the disease.
Overall, work closely with patients to support them in managing their new diagnosis with evidence-based pharmacologic and nonpharmacologic approaches. The importance of lifestyle changes including high-fiber diets, regular exercise, and weight loss should not be overlooked. Do not delay starting pharmacotherapy after diagnosing T2D and consider medication-specific and patient-specific factors to individualize therapy, improve adherence, and prevent complications.

Regardless of baseline glycemic control, offer patients who have ASCVD, or who are at high risk for it, an SGLT2 inhibitor (canagliflozin, dapagliflozin, or empagliflozin) or a long-acting GLP-1 receptor agonist (dulaglutide, liraglutide, or semaglutide).34,35 SGLT2 inhibitors reduced the risk for MACE by 11% in patients with established ASCVD.55 They also reduced a composite outcome of cardiovascular death or hospitalization for heart failure by 23% in patients with or without ASCVD or heart failure at baseline.55 GLP-1 receptor agonists offer a similar reduction in MACE to SGLT2 inhibitors, but they do not have significant effects in heart failure.56 Thiazolidinediones (TZDs), saxagliptin, and alogliptin should be avoided in patients with heart failure.57 TZDs may reduce the risk for recurrent stroke in patients with T2D.58
Chronic kidney disease (CKD). As with ASCVD, prioritize SGLT2 inhibitors and GLP-1 receptor agonists in patients with CKD. While both classes reduced the risk for progression of kidney disease such as macroalbuminuria, SGLT2 inhibitors offer additional benefits in their reduction of the worsening of estimated glomerular filtration rate, end-stage kidney disease, and renal death.56
Obesity. Consider the effect of each drug class on weight when making initial treatment choices, taking special care to minimize weight gain and potentially promote weight loss.34 The ADA prefers GLP-1 receptor agonists, but also suggests SGLT2 inhibitors in these patients. While all GLP-1 receptor agonists have an impact on weight, weekly subcutaneous semaglutide offers the most pronounced weight loss of 2 to 7 kg over 56 weeks.59 SGLT2 inhibitors promote sustainable weight loss to a lesser degree, contributing to an average loss of 3 kg at 2 years.60 Weight gain is common in patients taking sulfonylureas (2.01-2.3 kg)31 and insulin (3-9 kg weight gain in the first year)61 and should be avoided in patients with T2D and obesity.34
Hypoglycemia risk. In addition to counseling patients on hypoglycemia management and prescribing glucagon rescue kits, offer medications with no or very low risk for hypoglycemia (eg, GLP-1 receptor agonists, SGLT2 inhibitors, dipeptidyl peptidase-4 inhibitors, and TZDs). Generally, avoid insulin and sulfonylureas in patients in whom hypoglycemia is a major concern (eg, older adults, individuals with labile blood glucose levels).34 Patients with reduced renal function are at higher risk for hypoglycemia with insulin or sulfonylureas due to reduced drug clearance. However, insulin is often the only treatment for patients with advanced renal disease. Pay close attention to insulin dosing in patients with advanced renal disease, which may necessitate lower doses and smaller dose adjustments due to this risk.
Social determinants of health. Medication access and cost is a major burden in T2D management and should be considered for every patient. Compared with the period of 2005 to 2007, the annual cost of diabetes medications for an individual in 2015 to 2017 increased by 147%, rising from $1106 to $2727 per year.62 This increase is driven by the cost of insulin and newer medications without generic options.62 Identify local resources in your community, such as patient assistance programs and pharmacies with reduced-price generic prescription programs, which may be useful for patients who are underinsured or uninsured.
Continue to: Even if cost weren't an issue...
Even if cost weren’t an issue, many medications such as insulin and GLP-1 receptor agonists should be kept refrigerated and are only stable at room temperature for a limited time. Medications that are stable at room temperature should be prioritized in patients with limited or inconsistent access to refrigeration or unstable housing who may find it difficult to store their medications appropriately.
Do not delay insulin initiation in patients with high baseline A1C
Whenever possible, a GLP-1 receptor agonist is the preferred injectable medication to insulin. Starting insulin introduces numerous risks, including hypoglycemia, weight gain, and stigma. However, in the patient with newly diagnosed T2D, choose basal insulin when the baseline hyperglycemia is severe,34 as indicated by:
- blood glucose > 300 mg/dL (16.7 mmol/L),
- A1C > 10% (86 mmol/mol),
- symptoms of hyperglycemia (polyuria or polydipsia), or
- evidence of catabolism (weight loss, hypertriglyceridemia, ketosis).
Basal insulin analogs are preferred over NPH given their reduced variability, dosing, and hypoglycemic risk.35 Mixed insulins may be used if a patient is unable to afford an insulin analog, which can be quite costly. However, extensive counseling on dosing and management of hypoglycemia is crucial to patient safety with these agents. The ADA recommends initiating 0.1 to 0.2 units/kg of basal insulin daily or 10 units daily.34 The AACE follows this recommendation for patients with baseline A1C < 8%, but it proposes a more aggressive initiation of 0.2 to 0.3 units/kg/d for patients with baseline A1C > 8%.35 Titrate the dose by 2 units every 3 days to reach the target fasting blood glucose level. As hyperglycemia resolves, simplify the regimen and transition to noninsulin options per the previously discussed considerations.
It’s not just about glycemic control
In addition to the direct effects of hyperglycemia, a T2D diagnosis introduces an increased risk for ASCVD, a reduced ability to fight infection, and heightened risk for depression. Order a lipid panel at the time of T2D diagnosis and initiate lipid management as needed (TABLE 335,63,64). Both the ADA and the American Heart Association recommend starting a moderate-intensity statin as primary prevention for all patients with T2D between 40 and 75 years of age regardless of the 10-year ASCVD risk.63 The AACE uses specific lipid targets and recommends moderate- to high-intensity statin therapy for patients with T2D.35 All recommendations by professional organizations list high-intensity statins for patients with established ASCVD.
It is also vital to recommend that patients with newly diagnosed T2D remain up to date on all indicated vaccinations. They should promptly receive the hepatitis B and pneumococcal vaccines if they have not already done so for a previous indication. COVID-19 and annual influenza vaccines also should be prioritized for these patients.65
Finally, patients with diabetes are twice as likely to develop depression than patients without diabetes.66 Individuals with T2D and depression exhibit poorer medication adherence, lifestyle choices, and glycemic control.66 Screen for and treat these issues in all patients with T2D across the course of the disease.
Overall, work closely with patients to support them in managing their new diagnosis with evidence-based pharmacologic and nonpharmacologic approaches. The importance of lifestyle changes including high-fiber diets, regular exercise, and weight loss should not be overlooked. Do not delay starting pharmacotherapy after diagnosing T2D and consider medication-specific and patient-specific factors to individualize therapy, improve adherence, and prevent complications.

Low-carb breakfast key to lower glucose variability in T2D?
These findings from a 3-month randomized study in 121 patients in Canada and Australia were published online recently in the American Journal of Clinical Nutrition.
The researchers aimed to determine whether a low-carbohydrate, high-fat breakfast (focused around eggs), compared with a standard, low-fat control breakfast (designed to have no/minimal eggs), would improve blood glucose control in individuals with type 2 diabetes.
“We’ve determined that if the first meal of the day is low-carb and higher in protein and fat we can limit hyperglycemic swings,” lead author Barbara Oliveira, PhD, School of Health and Exercise Sciences, University of British Columbia, Kelowna, said in a press release from the university.
“Having fewer carbs for breakfast not only aligns better with how people with [type 2 diabetes] handle glucose throughout the day,” she noted, “but it also has incredible potential for people with [type 2 diabetes] who struggle with their glucose levels in the morning.”
“By making a small adjustment to the carb content of a single meal rather than the entire diet,” Dr. Oliveira added, “we have the potential to increase adherence significantly while still obtaining significant benefits.”
The researchers conclude that “this trial provides evidence that advice to consume a low-carbohydrate breakfast could be a simple, feasible, and effective approach to manage postprandial hyperglycemia and lower glycemic variability in people living with type 2 diabetes.”
Could breakfast tweak improve glucose control?
People with type 2 diabetes have higher levels of insulin resistance and greater glucose intolerance in the morning, the researchers write.
And consuming a low-fat, high-carbohydrate meal in line with most dietary guidelines appears to incur the highest hyperglycemia spike and leads to higher glycemic variability.
They speculated that eating a low-carb breakfast, compared with a low-fat breakfast, might be an easy way to mitigate this.
They recruited participants from online ads in three provinces in Canada and four states in Australia, and they conducted the study from a site in British Columbia and one in Wollongong, Australia.
The participants were aged 20-79 years and diagnosed with type 2 diabetes. They also had a current hemoglobin A1c < 8.5% and no allergies to eggs, and they were able to follow remote, online guidance.
After screening, the participants had a phone or video conference call with a member of the research team who explained the study.
The researchers randomly assigned 75 participants in Canada and 46 participants in Australia 1:1 to the low-carbohydrate intervention or the control intervention.
The participants had a mean age of 64 and 53% were women. They had a mean weight of 93 kg (204 lb), body mass index of 32 kg/m2, and A1c of 7.0%.
Registered dietitians in Canada and Australia each designed 8-10 recipes/menus for low-carb breakfasts and an equal number of recipes/menus for control (low-fat) breakfasts that were specific for those countries.
Each recipe contains about 450 kcal, and they are available in Supplemental Appendix 1A and 1B, with the article.
Each low-carbohydrate breakfast contains about 25 g protein, 8 g carbohydrates, and 37 g fat. For example, one breakfast is a three-egg omelet with spinach.
Each control (low-fat) recipe contains about 20 g protein, 56 g carbohydrates, and 15 g fat. For example, one breakfast is a small blueberry muffin and a small plain Greek yogurt.
The participants were advised to select one of these breakfasts every day and follow it exactly (they were also required to upload a photograph of their breakfast every morning). They were not given any guidance or calorie restriction for the other meals of the day.
The participants also filled in 3-day food records and answered a questionnaire about exercise, hunger, and satiety, at the beginning, middle, and end of the intervention.
They provided self-reported height, weight, and waist circumference, and they were given requisitions for blood tests for A1c to be done at a local laboratory, at the beginning and end of the intervention.
The participants also wore a continuous glucose monitor (CGM) during the first and last 14 days of the intervention.
Intervention improved CGM measures
There was no significant difference in the primary outcome, change in A1c, at the end of 12 weeks, in the two groups. The mean A1c decreased by 0.3% in the intervention group vs 0.1% in the control group (P = .06).
Similarly, in secondary outcomes, weight and BMI each decreased about 1% and waist circumference decreased by about 2.5 cm in each group at 12 weeks (no significant difference). There were also no significant differences in hunger, satiety, or physical activity between the two groups.
However, the 24-hour CGM data showed that mean and maximum glucose, glycemic variability, and time above range were all significantly lower in participants in the low-carbohydrate breakfast intervention group vs. those in the control group (all P < .05).
Time in range was significantly higher among participants in the intervention group (P < .05).
In addition, the 2-hour postprandial CGM data showed that mean glucose and maximum glucose after breakfast were lower in participants in the low-carbohydrate breakfast group than in the control group.

Medicaid patients with heart failure get poor follow-up after hospital discharge
Nearly 60% of Medicaid-covered adults with concurrent diabetes and heart failure did not receive guideline-concordant postdischarge care within 7-10 days of leaving the hospital, according to a large Alabama study. Moreover, affected Black and Hispanic/other Alabamians were less likely than were their White counterparts to receive recommended postdischarge care.
In comparison with White participants, Black and Hispanic adults were less likely to have any postdischarge ambulatory care visits after HF hospitalization or had a delayed visit, according to researchers led by Yulia Khodneva, MD, PhD, an internist at the University of Alabama at Birmingham. “This is likely a reflection of a structural racism and implicit bias against racial and ethnic minorities that persists in the U.S. health care system,” she and her colleagues wrote.
The findings point to the need for strategies to improve access to postdischarge care for lower-income HF patients.
Among U.S. states, Alabama is the sixth-poorest, the third in diabetes prevalence (14%), and has the highest rates of heart failure hospitalizations and cardiovascular mortality, the authors noted.
Study details
The cohort included 9,857 adults with diabetes and first hospitalizations for heart failure who were covered by Alabama Medicaid during 2010-2019. The investigators analyzed patients’ claims for ambulatory care (any, primary, cardiology, or endocrinology) within 60 days of discharge.
The mean age of participants was 53.7 years; 47.3% were Black; 41.8% non-Hispanic White; and 10.9% Hispanic/other, with other including those identifying as non-White Hispanic, American Indian, Pacific Islander, and Asian. About two-thirds (65.4%) of participants were women.
Analysis revealed low rates of follow-up care after hospital discharge; 26.7% had an ambulatory visit within 0-7 days, 15.2% within 8-14 days, 31.3% within 15-60 days, and 26.8% had no follow-up visit at all. Of those having a follow-up visit, 71% saw a primary care physician and 12% saw a cardiologist.
In contrast, a much higher proportion of heart failure patients in a Swedish registry – 63% – received ambulatory follow-up in cardiology.
Ethnic/gender/age disparities
Black and Hispanic/other adults were less likely to have any postdischarge ambulatory visit (P <.0001) or had the visit delayed by 1.8 days (P = .0006) and 2.8 days (P = .0016), respectively. They were less likely to see a primary care physician than were non-Hispanic White adults: adjusted incidence rate ratio, 0.96 (95% confidence interval [CI], 0.91-1.00) and 0.91 (95% CI, 0.89-0.98), respectively.
Men and those with longer-standing heart failure were less likely to be seen in primary care, while the presence of multiple comorbidities was associated with a higher likelihood of a postdischarge primary care visit. Men were more likely to be seen by a cardiologist, while older discharged patients were less likely to be seen by an endocrinologist within 60 days. There was a U-shaped relationship between the timing of the first postdischarge ambulatory visit and all-cause mortality among adults with diabetes and heart failure. Higher rates of 60-day all-cause mortality were observed both in those who had seen a provider within 0-7 days after discharge and in those who had not seen any provider during the 60-day study period compared with those having an ambulatory care visit within 7-14 or 15-60 days. “The group with early follow-up (0-7 days) likely represents a sicker population of patients with heart failure with more comorbidity burden and higher overall health care use, including readmissions, as was demonstrated in our analysis,” Dr. Khodneva and associates wrote. “Interventions that improve access to postdischarge ambulatory care for low-income patients with diabetes and heart failure and eliminate racial and ethnic disparities may be warranted,” they added.
This study was supported by the National Institute of Diabetes and Digestive and Kidney Diseases and the University of Alabama at Birmingham Diabetes Research Center. Dr. Khodneva reported funding from the University of Alabama at Birmingham and the Forge Ahead Center as well as from the NIDDK, the National Institutes of Health, the Agency for Healthcare Research and Quality, and the Alabama Medicaid Agency. Coauthor Emily Levitan, ScD, reported research funding from Amgen and has served on Amgen advisory boards. She has also served as a scientific consultant for a research project funded by Novartis.

The cohort included 9,857 adults with diabetes and first hospitalizations for heart failure who were covered by Alabama Medicaid during 2010-2019. The investigators analyzed patients’ claims for ambulatory care (any, primary, cardiology, or endocrinology) within 60 days of discharge.
The mean age of participants was 53.7 years; 47.3% were Black; 41.8% non-Hispanic White; and 10.9% Hispanic/other, with other including those identifying as non-White Hispanic, American Indian, Pacific Islander, and Asian. About two-thirds (65.4%) of participants were women.
Analysis revealed low rates of follow-up care after hospital discharge; 26.7% had an ambulatory visit within 0-7 days, 15.2% within 8-14 days, 31.3% within 15-60 days, and 26.8% had no follow-up visit at all. Of those having a follow-up visit, 71% saw a primary care physician and 12% saw a cardiologist.
In contrast, a much higher proportion of heart failure patients in a Swedish registry – 63% – received ambulatory follow-up in cardiology.
Ethnic/gender/age disparities
Black and Hispanic/other adults were less likely to have any postdischarge ambulatory visit (P <.0001) or had the visit delayed by 1.8 days (P = .0006) and 2.8 days (P = .0016), respectively. They were less likely to see a primary care physician than were non-Hispanic White adults: adjusted incidence rate ratio, 0.96 (95% confidence interval [CI], 0.91-1.00) and 0.91 (95% CI, 0.89-0.98), respectively.
Men and those with longer-standing heart failure were less likely to be seen in primary care, while the presence of multiple comorbidities was associated with a higher likelihood of a postdischarge primary care visit. Men were more likely to be seen by a cardiologist, while older discharged patients were less likely to be seen by an endocrinologist within 60 days. There was a U-shaped relationship between the timing of the first postdischarge ambulatory visit and all-cause mortality among adults with diabetes and heart failure. Higher rates of 60-day all-cause mortality were observed both in those who had seen a provider within 0-7 days after discharge and in those who had not seen any provider during the 60-day study period compared with those having an ambulatory care visit within 7-14 or 15-60 days. “The group with early follow-up (0-7 days) likely represents a sicker population of patients with heart failure with more comorbidity burden and higher overall health care use, including readmissions, as was demonstrated in our analysis,” Dr. Khodneva and associates wrote. “Interventions that improve access to postdischarge ambulatory care for low-income patients with diabetes and heart failure and eliminate racial and ethnic disparities may be warranted,” they added.
This study was supported by the National Institute of Diabetes and Digestive and Kidney Diseases and the University of Alabama at Birmingham Diabetes Research Center. Dr. Khodneva reported funding from the University of Alabama at Birmingham and the Forge Ahead Center as well as from the NIDDK, the National Institutes of Health, the Agency for Healthcare Research and Quality, and the Alabama Medicaid Agency. Coauthor Emily Levitan, ScD, reported research funding from Amgen and has served on Amgen advisory boards. She has also served as a scientific consultant for a research project funded by Novartis.
Nearly 60% of Medicaid-covered adults with concurrent diabetes and heart failure did not receive guideline-concordant postdischarge care within 7-10 days of leaving the hospital, according to a large Alabama study. Moreover, affected Black and Hispanic/other Alabamians were less likely than were their White counterparts to receive recommended postdischarge care.
In comparison with White participants, Black and Hispanic adults were less likely to have any postdischarge ambulatory care visits after HF hospitalization or had a delayed visit, according to researchers led by Yulia Khodneva, MD, PhD, an internist at the University of Alabama at Birmingham. “This is likely a reflection of a structural racism and implicit bias against racial and ethnic minorities that persists in the U.S. health care system,” she and her colleagues wrote.
The findings point to the need for strategies to improve access to postdischarge care for lower-income HF patients.
Among U.S. states, Alabama is the sixth-poorest, the third in diabetes prevalence (14%), and has the highest rates of heart failure hospitalizations and cardiovascular mortality, the authors noted.

Continuous glucose monitors come to hospitals
But that technological future will require ensuring that the monitoring devices are as accurate as the conventional method, experts told this news organization.
In 2020, the U.S. Food and Drug Administration enabled in-hospital use of CGMs to reduce contact between patients and health care providers during the COVID-19 pandemic. Diabetes is a risk factor for more severe COVID, meaning that many patients with the infection also required ongoing care for their blood sugar problems.
Prior to the pandemic, in-person finger-stick tests were the primary means of measuring glucose for hospitalized patients with diabetes.
The trouble is that finger-stick measurements quickly become inaccurate.
“Glucose is a measurement that changes pretty rapidly,” said Eileen Faulds, RN, PhD, an endocrinology nurse and health services researcher at the Ohio State University, Columbus. Finger sticks might occur only four or five times per day, Dr. Faulds noted, or as often as every hour for people who receive insulin intravenously. But even that more frequent pace is far from continuous.
“With CGM we can get the glucose level in real time,” Dr. Faulds said.
Dr. Faulds is lead author of a new study in the Journal of Diabetes Science and Technology, which shows that nurses in the ICU believe that using continuous monitors, subcutaneous filaments connected to sensors that regularly report glucose levels, enables better patient care than does relying on periodic glucose tests alone. Nurses still used traditional finger sticks, which Dr. Faulds notes are highly accurate at the time of the reading.
In a 2022 study, glucose levels generated by CGM and those measured by finger sticks varied by up to 14%. A hybrid care model combining CGMs and finger stick tests may emerge, Dr. Faulds said.
A gusher of glucose data
People with diabetes have long been able to use CGMs in their daily lives, which typically report the glucose value to a smartphone or watch. The devices are now part of hospital care as well. In 2022, the Food and Drug Administration granted a breakthrough therapy designation to the company Dexcom for use of its CGMs to manage care of people with diabetes in hospitals.
One open question is how often CGMs should report glucose readings for optimum patient health. Dexcom’s G6 CGM reports glucose levels every five minutes, for example, whereas Abbott’s FreeStyle Libre 2 delivers glucose values every minute.
“We wouldn’t look at each value, we would look at the big picture,” to determine if a patient is at risk of becoming hyper- or hypoglycemic, said Lizda Guerrero-Arroyo, MD, a postdoctoral fellow in endocrinology at the Emory University School of Medicine, Atlanta. Dr. Guerrero-Arroyo recently reported that clinicians in multiple ICUs began to use CGMs in conjunction with finger sticks during the pandemic and felt the devices could reduce patient discomfort.
“A finger stick is very painful,” Dr. Guerrero-Arroyo said, and a bottleneck for nursing staff who administer these tests. In contrast, Dr. Faulds said, CGM placement is essentially painless and requires less labor on the ward to manage.
Beyond use in the ICU, clinicians are also experimenting with use of CGMs to monitor blood sugar levels in people with diabetes who are undergoing general surgery. And other researchers are describing how to integrate data from CGMs into patient care tools such as the electronic health record, although a standard way to do this does not yet exist.
Assuming CGMs remain part of the mix for in-hospital care of people with diabetes, clinicians may mainly need trend summaries of how glucose levels rise and fall over time, said data scientist Samantha Spierling Bagsic, PhD, of the Scripps Whittier Diabetes Institute, San Diego. Dr. Guerrero-Arroyo said that she shares that vision. But a minute-by-minute analysis of glucose levels also may be necessary to get a granular sense of how changing a patient’s insulin level affects their blood sugar, Dr. Spierling Bagsic said.
“We need to figure out what data different audiences need, how often we need to measure glucose, and how to present that information to different audiences in different ways,” said Dr. Spierling Bagsic, a co-author of the study about integrating CGM data into patient care tools.
The wider use of CGMs in hospitals may be one silver lining of the COVID-19 pandemic. As an inpatient endocrinology nurse, Dr. Faulds said that she wanted to use CGMs prior to the outbreak, but at that point, a critical mass of studies about their benefits was missing.
“We all know the terrible things that happened during the pandemic,” Dr. Faulds said. “But it gave us the allowance to use CGMs, and we saw that nurses loved them.”
Dr. Faulds reports relationships with Dexcom and Insulet and has received an honorarium from Medscape. Dr. Guerrero-Arroyo and Dr. Spierling Bagsic reported no financial conflicts of interest.

FDA warns people to avoid compounded semaglutide medicines
Compounded medicines are not FDA approved but are allowed to be made during an official drug shortage. Ozempic and Wegovy are currently on the FDA’s shortage list, but the federal agency warned that it has received reports of people experiencing “adverse events” after using compounded versions of the drugs. (The FDA did not provide details of those events or where the drugs involved were compounded.)
Agency officials are concerned that the compounded versions may contain ingredients that sound like the brand name drugs’ active ingredient, semaglutide, but are different because the ingredients are in salt form.
“Patients should be aware that some products sold as ‘semaglutide’ may not contain the same active ingredient as FDA-approved semaglutide products and may be the salt formulations,” the FDA warning stated. “Products containing these salts, such as semaglutide sodium and semaglutide acetate, have not been shown to be safe and effective.”
The agency said salt forms don’t meet the criteria for compounding during a shortage and sent a letter to the National Association of Boards of Pharmacy expressing “concerns with use of the salt forms in compounded products.”
Patients and health care providers should be aware that “compounded drugs are not FDA approved, and the agency does not verify the safety or effectiveness of compounded drugs,” the FDA explained in its statement.
The Alliance for Pharmacy Compounding’s board of directors said in a statement that some compounders’ arguments for the suitability of semaglutide sodium are “worthy of discussion,” but the board did not endorse those arguments.
For people who use an online pharmacy, the FDA recommends checking the FDA’s website BeSafeRx to check its credentials.

Positive top-line results for cannabinoid-based med for nerve pain
, new top-line results released by Zelira Therapeutics suggest.
“The implications of these results for patients are incredibly promising,” principal investigator Bryan Doner, DO, medical director of HealthyWays Integrated Wellness Solutions, Gibsonia, Pa., said in a news release.
“Through this rigorously designed study, we have demonstrated that ZLT-L-007 is a safe, effective, and well-tolerated alternative for patients who would typically seek a Lyrica-level of pain relief,” he added.
The observational, nonblinded trial tested the efficacy, safety, and tolerability of ZLT-L-007 against pregabalin in 60 adults with diabetic nerve pain.
The study had three groups with 20 patients each (pregabalin alone, pregabalin plus ZLT-L-007, and ZLT-L-007 alone).
Top-line results show the study met its primary endpoint for change in daily pain severity as measured by the percent change from baseline at 30, 60, and 90 days on the Numerical Rating Scale.
For the pregabalin-only group, there was a reduction in symptom severity at all follow-up points, ranging from 20% to 35% (median percent change from baseline), the company said.
For the ZLT-L-007 only group, there was about a 33% reduction in symptom severity at 30 days, and 71% and 78% reduction, respectively, at 60 and 90 days, suggesting a larger improvement in symptom severity than with pregabalin alone, the company said.
For the pregabalin plus ZLT-L-007 group, there was a moderate 20% reduction in symptom severity at 30 days, but a larger reduction at 60 and 90 days (50% and 72%, respectively), which indicates substantially greater improvement in symptom severity than with pregabalin alone, the company said.
The study also met secondary endpoints, including significant decreases in daily pain severity as measured by the Visual Analog Scale and measurable changes in the short-form McGill Pain Questionnaire and Neuropathic Pain Symptom Inventory.
Dr. Doner noted that the top-line data showed “no serious adverse events, and participants’ blood pressure and other safety vitals remained unaffected throughout. This confirms that ZLT-L-007 is a well-tolerated product that delivers statistically significant pain relief, surpassing the levels achieved by Lyrica.”
The company plans to report additional insights from the full study, as they become available, during fiscal year 2023-2024.

Troponin to ID diabetes patients with silent heart disease?
– based on data from a representative sample of more than 10,000 U.S. adults.
The finding suggests hs-cTnT maybe a useful marker for adults with diabetes who could benefit from more aggressive CVD risk reduction despite having no clinical indications of CVD.
The results “highlight the substantial burden of subclinical CVD in persons with diabetes and emphasize the importance of early detection and treatment of CVD for this high-risk population,” say the authors of the research, published in the Journal of the American Heart Association.
“This is the first study to examine subclinical CVD, defined by elevated cardiac biomarkers, in a nationally representative population of adults with or without diabetes. It provides novel information on the high burden of subclinical CVD [in American adults with diabetes] and the potential utility of hs-cTnT for monitoring this risk in people with diabetes,” said Elizabeth Selvin, PhD, senior author and a professor of epidemiology at Johns Hopkins University, Baltimore.
“What we are seeing is that many people with type 2 diabetes who have not had a heart attack or a history of cardiovascular disease are at high risk for cardiovascular complications,” added Dr. Selvin in an AHA press release. “When we look at the whole population of people diagnosed with type 2 diabetes, about 27 million adults in the U.S., according to the [Centers for Disease Control and Prevention], some are at low risk and some are at high risk for cardiovascular disease, so the open question is: ‘Who is most at risk?’ These cardiac biomarkers give us a window into cardiovascular risk in people who otherwise might not be recognized as highest risk.”
“Our results provide evidence to support use of cardiac biomarkers for routine risk monitoring in high-risk populations such as people with diabetes,” Dr. Selvin noted in an interview.
Need for aggressive CVD risk reduction
The findings also indicate that people with diabetes and an elevated hs-cTnT “should be targeted for aggressive cardiovascular risk reduction, including lifestyle interventions, weight loss, and treatment with statins, blood pressure medications, and cardioprotective therapies such as sodium-glucose cotransporter 2 (SGLT-2) inhibitors and glucagonlike peptide-1 (GLP-1) receptor agonists,” Dr. Selvin added.
“Cholesterol is often the factor that we target to reduce the risk of cardiovascular disease in people with type 2 diabetes,” she observed. “However, type 2 diabetes may have a direct effect on the heart not related to cholesterol levels. If type 2 diabetes is directly causing damage to the small vessels in the heart unrelated to cholesterol plaque buildup, then cholesterol-lowering medications are not going to prevent cardiac damage,” Dr. Selvin explained. “Our research suggests that additional non–statin-related therapies are needed to lower the cardiovascular disease risk in people with type 2 diabetes.”
However, she noted that a necessary step prior to formally recommending such a strategy is to run clinical trials to assess the efficacy of specific treatments, such as SGLT-2 inhibitors and GLP-1 agonists, in people with diabetes and elevated hs-cTnT.
“Randomized controlled trials would be best to test the relevance of measuring these biomarkers to assess risk in asymptomatic people with diabetes,” as well as prospective study of the value of hs-cTnT to guide treatment, commented Robert H. Eckel, MD, an endocrinologist affiliated with the University of Colorado at Denver, Aurora.
“I doubt measurements [of hs-cTnT] would be reimbursed [by third-party payers] if carried out without such outcome data,” he added.
Dr. Eckel also highlights the need to further validate in additional cohorts the link between elevations in hs-cTnT and CVD events in adults with diabetes, and to confirm that elevated levels of another cardiac biomarker – N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) – do not work as well as troponin as a risk marker for people with diabetes, another finding of the study.
ADA report already recommends testing these biomarkers for HF
However, a consensus report published in 2022 by the American Diabetes Association laid out the case for routinely and regularly measuring levels of both high sensitivity cardiac troponin and natriuretic peptides in people with diabetes for early identification of incident heart failure.
“Among individuals with diabetes, measurement of a natriuretic peptide or high-sensitivity cardiac troponin is recommended on at least a yearly basis to identify the earliest heart failure stages and implement strategies to prevent transition to symptomatic heart failure,” noted the ADA consensus report on heart failure.
The new study run by Dr. Selvin and coauthors used data collected by the National Health and Nutrition Examination Survey (NHANES) between 1999 and 2004 from U.S. adults who were at least 20 years old and had no history of CVD: myocardial infarction, stroke, coronary heart disease, or heart failure. This included 9,273 people without diabetes and 1,031 with diabetes, defined as a prior diagnosis or hemoglobin A1c of at least 6.5%.
“Cardiovascular risk varies substantially in adults with type 2 diabetes, highlighting the need for accurate risk stratification,” the authors observed.
All study participants had recorded measures of hs-cTnT and NT-proBNP.
The researchers considered an hs-cTnT level of greater than 14 ng/L and an NT-proBNP level of greater than 125 pg/mL as indicators of subclinical CVD.
The crude prevalence of elevated NT-proBNP was 33.4% among those with diabetes and 16.1% in those without diabetes. Elevated hs-cTnT occurred in 19% of those with diabetes and in 5% of those without diabetes. Elevated levels of both markers existed in 9% of those with diabetes and in 3% of those without diabetes.
“Approximately one in three adults with diabetes had subclinical CVD, with 19% having elevated levels of hs-cTnT, 23% having elevated NT-proBNP, and 9% having elevations in both cardiac biomarkers,” the researchers noted.
Diabetes linked with a doubled prevalence of elevated hs-cTnT
After adjustment for several demographic variables as well as traditional CVD risk factors, people with diabetes had a significant 98% higher rate of elevated hs-cTnT, compared with those without diabetes. But after similar adjustments, the rate of elevated NT-proBNP was significantly lower among people with diabetes, compared with controls, by a relative reduction of 24%.
“Our findings suggest that, in people with diabetes, hs-cTnT may be more useful [than NT-proBNP] for general risk monitoring, as its interpretation is less complicated,” said Dr. Selvin, who explained that “NT-proBNP is affected by overweight and obesity.”
In people with diabetes, the age-adjusted prevalence of elevated hs-cTnT ran higher in those with longer duration diabetes, and in those with less well-controlled diabetes based on a higher level of A1c. Neither of these factors showed any significant relationship with measured levels of NT-proBNP.
Further analysis linked the NHANES findings during 1999-2004 with U.S. national death records through the end of 2019. This showed that elevated levels of both hs-cTnT and NT-proBNP significantly linked with subsequently higher rates of all-cause mortality among people with diabetes. Elevated hs-cTnT linked with a 77% increased mortality and NT-proBNP linked with a 78% increased rate, compared with people with diabetes and no elevations in these markers, after adjustment for demographic variables and CVD risk factors.
However, for the outcome of cardiovascular death, elevated hs-cTnT linked with a nonsignificant 54% relative increase, while elevated NT-proBNP linked with a significant 2.46-fold relative increase.
The study “adds new data on biomarkers that are not routinely measured in asymptomatic people with or without diabetes” and the relationships of these markers to CVD mortality and all-cause mortality, Dr. Eckel concluded.
The study received no commercial funding, but used reagents donated by Abbott Laboratories, Ortho Clinical Diagnostics, Roche Diagnostics, and Siemens Healthcare Diagnostics. Dr. Selvin and Dr. Eckel had no disclosures.

FROM THE JOURNAL OF THE AMERICAN HEART ASSOCIATION
FDA approves new drug, sotagliflozin, for heart failure
Sotagliflozin, a novel agent that inhibits sodium-glucose cotransporter 1 as well as SGLT2, has received marketing approval from the Food and Drug Administration for reducing the risk for cardiovascular death, hospitalization for heart failure, and urgent heart failure visits in patients with heart failure, and also for preventing these same events in patients with type 2 diabetes, chronic kidney disease (CKD), and other cardiovascular disease risk factors.
This puts sotagliflozin in direct competition with two SGLT2 inhibitors, dapagliflozin (Farxiga) and empagliflozin (Jardiance), that already have indications for preventing heart failure hospitalizations in patients with heart failure as well as approvals for type 2 diabetes and preservation of renal function.
Officials at Lexicon Pharmaceuticals, the company that developed and will market sotagliflozin under the trade name Inpefa, said in a press release that they expect U.S. sales of the agent to begin before the end of June 2023. The release also highlighted that the approval broadly covered use in patients with heart failure across the full range of both reduced and preserved left ventricular ejection fractions.
They base this niche target for sotagliflozin on results from the SOLOIST-WHF trial, which randomized 1,222 patients with type 2 diabetes recently hospitalized for worsening heart failure and showed a significant 33% reduction in the rate of deaths from cardiovascular causes and hospitalizations and urgent visits for heart failure, compared with control patients during a median 9 months of follow-up. Nearly half of the enrolled patients received their first dose while still hospitalized, while the other half received their first dose a median of 2 days after hospital discharge. The drug appeared safe.
Cutting heart failure rehospitalizations in half
An exploratory post hoc analysis of SOLOIST-WHF showed that treatment with sotagliflozin cut the rate of rehospitalizations roughly in half after both 30 and 90 days compared with control patients, according to an abstract presented at the 2022 annual scientific sessions of the AHA that has not yet been published in a peer-reviewed journal.
The only SGLT2 inhibitor tested so far when initiated in patients during hospitalization for heart failure is empagliflozin, in the EMPULSE trial, which randomized 530 patients. EMPULSE also showed that starting an SGLT2 inhibitor in this setting was safe and resulted in significant clinical benefit, the study’s primary endpoint, defined as a composite of death from any cause, number of heart failure events, and time to first heart failure event, or a 5-point or greater difference in change from baseline in the Kansas City Cardiomyopathy Questionnaire Total Symptom Score at 90 days.
In the DELIVER trial, which tested dapagliflozin in patients with heart failure with preserved ejection fraction, roughly 10% of patients started study treatment during or within 30 days of heart failure hospitalization, and in this subgroup, dapagliflozin appeared as effective as it was in the other 90% of patients who did not start the drug during an acute or subacute phase.
Despite the SOLOIST-WHF evidence for sotagliflozin’s safety and efficacy in this economically important clinical setting, some experts say the drug faces an uphill path as it contends for market share against two solidly established, albeit dramatically underused, SGLT2 inhibitors. (Recent data document that 20% or fewer of U.S. patients eligible for treatment with an SGLT2 inhibitor receive it, such as a review of 49,000 patients hospitalized during 2021-2022 with heart failure with reduced ejection fraction.)
Others foresee a clear role for sotagliflozin, particularly because of additional facets of the drug’s performance in trials that they perceive give it an edge over dapagliflozin and empagliflozin. This includes evidence that sotagliflozin treatment uniquely (within the SGLT2 inhibitor class) cuts the rate of strokes and myocardial infarctions, as well as evidence of its apparent ability to lower hemoglobin A1c levels in patients with type 2 diabetes and with an estimated glomerular filtration rate below 30 mL/min per 1.73 m2, a property likely linked to inhibition of SGLT1 in the gut that dampens intestinal glucose absorption.
Sotagliflozin uptake ‘will be a challenge’
“It will be a challenge” for sotagliflozin uptake, given the head start that both dapagliflozin and empagliflozin have had as well-documented agents for patients with heart failure, commented Javed Butler, MD, a heart failure clinician and trialist who is president of the Baylor Scott & White Research Institute in Dallas.
Given the position dapagliflozin and empagliflozin currently have in U.S. heart failure management – with the SGLT2 inhibitor class called out in guidelines as foundational for treating patients with heart failure with reduced ejection fraction and likely soon for heart failure with preserved ejection fraction as well – “I can’t imagine [sotagliflozin] will be considered a preferred option,” Dr. Butler said in an interview.
Another expert was even more dismissive of sotagliflozin’s role.
“There is no persuasive evidence that sotagliflozin has any advantages, compared with the SGLT2 inhibitors, for the treatment of heart failure,” said Milton Packer, MD, a heart failure specialist and trialist at Baylor University Medical Center, Dallas. “I do not see why U.S. physicians might pivot from established SGLT2 inhibitors to sotagliflozin,” unless it was priced “at a very meaningful discount to available SGLT2 inhibitors.”
At the time it announced the FDA’s approval, Lexicon did not provide details on how it would price sotagliflozin. Existing retail prices for dapagliflozin and empagliflozin run about $550-$600/month, a price point that has contributed to slow U.S. uptake of the drug class. But experts anticipate a dramatic shake-up of the U.S. market for SGLT2 inhibitors with expected introduction of a generic SGLT2 inhibitor formulation by 2025, a development that could further dampen sotagliflozin’s prospects.
Other experts are more optimistic about the new agent’s uptake, perhaps none more than Deepak L. Bhatt, MD, MPH, who led both pivotal trials that provide the bulk of sotagliflozin’s evidence package.
In addition to SOLOIST-WHF, Dr. Bhatt also headed the SCORED trial, with 10,584 patients with type 2 diabetes, CKD, and risks for cardiovascular disease randomized to sotagliflozin or placebo and followed for a median of 16 months. The primary result showed that sotagliflozin treatment cut the combined rate of deaths from cardiovascular causes, hospitalizations for heart failure, and urgent visits for heart failure by a significant 26% relative to control patients.
A clear MACE benefit
“The data from SOLOIST-WHF and SCORED look at least as good as the data for the SGLT2 inhibitors for heart failure, and what appears to be different are the rates for MI and stroke in SCORED,” said Dr. Bhatt, director of Mount Sinai Heart, New York.
“I believe the rate of major adverse cardiovascular events [MACE] were reduced [in SCORED], and this is different from the SGLT2 inhibitors,” he said in an interview.
In 2022, Dr. Bhatt reported results from a prespecified secondary analysis of SCORED that showed that treatment with sotagliflozin cut the rate of MACE by a significant 21%-26%, compared with placebo. This finding was, in part, driven by the first data to show a substantial benefit from an SGLT inhibitor on stroke rates.
And while SCORED did not report a significant benefit for slowing progression of CKD, subsequent post hoc analyses have suggested this advantage also in as-yet-unpublished findings, Dr. Bhatt added.
But he said he doubted nephrologists will see it as a first-line agent for slowing CKD progression – an indication already held by dapagliflozin, pending for empagliflozin, and also in place for a third SGLT2 inhibitor, canagliflozin (Invokana) – because sotagliflozin lacks clear significant and prespecified evidence for this effect.
Dr. Bhatt also acknowledged the limitation of sotagliflozin compared with the SGLT2 inhibitors as an agent for glucose control, again because of no evidence for this effect from a prospective analysis and no pending indication for type 2 diabetes treatment. But the SCORED data showed a clear A1c benefit, even in patients with severely reduced renal function.
Mostly for cardiologists? ‘Compelling’ reductions in MIs and strokes
That may mean sotagliflozin “won’t get much use by endocrinologists nor by primary care physicians,” commented Carol L. Wysham, MD, an endocrinologist with MultiCare in Spokane, Wash.
Sotagliflozin “will be a cardiology drug,” and will “have a hard time” competing with the SGLT2 inhibitors, she predicted.
Dr. Bhatt agreed that sotagliflozin “will be perceived as a drug for cardiologists to prescribe. I don’t see endocrinologists, nephrologists, and primary care physicians reaching for this drug if it has a heart failure label.” But, he added, “my hope is that the company files for additional indications. It deserves an indication for glycemic control.”
The evidence for a heart failure benefit from sotagliflozin is “valid and compelling,” and “having this option is great,” commented Mikhail N. Kosiborod, MD, a cardiologist, vice president of research at Saint Luke’s Health System, and codirector of the Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute in Kansas City, Mo. But, he added, “it will be a reasonably tall task for sotagliflozin to come from behind and be disruptive in a space where there are already two well-established SGLT2 inhibitors” approved for preventing heart failure hospitalizations, “with a lot of data to back them up,”
The feature that sets sotagliflozin apart from the approved SGLT2 inhibitors is the “really compelling decrease” it produced in rates of MIs and strokes “that we simply do not see with SGLT2 inhibitors,” Dr. Kosiborod said in an interview.
He also cited results from SCORED that suggest “a meaningful reduction in A1c” when indirectly compared with SGLT2 inhibitors, especially in patients with more severe CKD. The lack of a dedicated A1c-lowering trial or an approved type 2 diabetes indication “will not be a problem for cardiologists,” he predicted, but also agreed that it is less likely to be used by primary care physicians in low-risk patients.
“I can see myself prescribing sotagliflozin,” said Dr. Kosiborod, a SCORED coinvestigator, especially for patients with coexisting type 2 diabetes, heart failure, CKD, and atherosclerotic cardiovascular disease. These patients may get “more bang for the buck” because of a reduced risk for MI and stroke, making sotagliflozin “a solid consideration in these patients if the economic factors align.”

Sotagliflozin, a novel agent that inhibits sodium-glucose cotransporter 1 as well as SGLT2, has received marketing approval from the Food and Drug Administration for reducing the risk for cardiovascular death, hospitalization for heart failure, and urgent heart failure visits in patients with heart failure, and also for preventing these same events in patients with type 2 diabetes, chronic kidney disease (CKD), and other cardiovascular disease risk factors.
This puts sotagliflozin in direct competition with two SGLT2 inhibitors, dapagliflozin (Farxiga) and empagliflozin (Jardiance), that already have indications for preventing heart failure hospitalizations in patients with heart failure as well as approvals for type 2 diabetes and preservation of renal function.
Officials at Lexicon Pharmaceuticals, the company that developed and will market sotagliflozin under the trade name Inpefa, said in a press release that they expect U.S. sales of the agent to begin before the end of June 2023. The release also highlighted that the approval broadly covered use in patients with heart failure across the full range of both reduced and preserved left ventricular ejection fractions.
They base this niche target for sotagliflozin on results from the SOLOIST-WHF trial, which randomized 1,222 patients with type 2 diabetes recently hospitalized for worsening heart failure and showed a significant 33% reduction in the rate of deaths from cardiovascular causes and hospitalizations and urgent visits for heart failure, compared with control patients during a median 9 months of follow-up. Nearly half of the enrolled patients received their first dose while still hospitalized, while the other half received their first dose a median of 2 days after hospital discharge. The drug appeared safe.
Cutting heart failure rehospitalizations in half
An exploratory post hoc analysis of SOLOIST-WHF showed that treatment with sotagliflozin cut the rate of rehospitalizations roughly in half after both 30 and 90 days compared with control patients, according to an abstract presented at the 2022 annual scientific sessions of the AHA that has not yet been published in a peer-reviewed journal.
The only SGLT2 inhibitor tested so far when initiated in patients during hospitalization for heart failure is empagliflozin, in the EMPULSE trial, which randomized 530 patients. EMPULSE also showed that starting an SGLT2 inhibitor in this setting was safe and resulted in significant clinical benefit, the study’s primary endpoint, defined as a composite of death from any cause, number of heart failure events, and time to first heart failure event, or a 5-point or greater difference in change from baseline in the Kansas City Cardiomyopathy Questionnaire Total Symptom Score at 90 days.
In the DELIVER trial, which tested dapagliflozin in patients with heart failure with preserved ejection fraction, roughly 10% of patients started study treatment during or within 30 days of heart failure hospitalization, and in this subgroup, dapagliflozin appeared as effective as it was in the other 90% of patients who did not start the drug during an acute or subacute phase.
Despite the SOLOIST-WHF evidence for sotagliflozin’s safety and efficacy in this economically important clinical setting, some experts say the drug faces an uphill path as it contends for market share against two solidly established, albeit dramatically underused, SGLT2 inhibitors. (Recent data document that 20% or fewer of U.S. patients eligible for treatment with an SGLT2 inhibitor receive it, such as a review of 49,000 patients hospitalized during 2021-2022 with heart failure with reduced ejection fraction.)
Others foresee a clear role for sotagliflozin, particularly because of additional facets of the drug’s performance in trials that they perceive give it an edge over dapagliflozin and empagliflozin. This includes evidence that sotagliflozin treatment uniquely (within the SGLT2 inhibitor class) cuts the rate of strokes and myocardial infarctions, as well as evidence of its apparent ability to lower hemoglobin A1c levels in patients with type 2 diabetes and with an estimated glomerular filtration rate below 30 mL/min per 1.73 m2, a property likely linked to inhibition of SGLT1 in the gut that dampens intestinal glucose absorption.
Sotagliflozin uptake ‘will be a challenge’
“It will be a challenge” for sotagliflozin uptake, given the head start that both dapagliflozin and empagliflozin have had as well-documented agents for patients with heart failure, commented Javed Butler, MD, a heart failure clinician and trialist who is president of the Baylor Scott & White Research Institute in Dallas.
Given the position dapagliflozin and empagliflozin currently have in U.S. heart failure management – with the SGLT2 inhibitor class called out in guidelines as foundational for treating patients with heart failure with reduced ejection fraction and likely soon for heart failure with preserved ejection fraction as well – “I can’t imagine [sotagliflozin] will be considered a preferred option,” Dr. Butler said in an interview.
Another expert was even more dismissive of sotagliflozin’s role.
“There is no persuasive evidence that sotagliflozin has any advantages, compared with the SGLT2 inhibitors, for the treatment of heart failure,” said Milton Packer, MD, a heart failure specialist and trialist at Baylor University Medical Center, Dallas. “I do not see why U.S. physicians might pivot from established SGLT2 inhibitors to sotagliflozin,” unless it was priced “at a very meaningful discount to available SGLT2 inhibitors.”
At the time it announced the FDA’s approval, Lexicon did not provide details on how it would price sotagliflozin. Existing retail prices for dapagliflozin and empagliflozin run about $550-$600/month, a price point that has contributed to slow U.S. uptake of the drug class. But experts anticipate a dramatic shake-up of the U.S. market for SGLT2 inhibitors with expected introduction of a generic SGLT2 inhibitor formulation by 2025, a development that could further dampen sotagliflozin’s prospects.
Other experts are more optimistic about the new agent’s uptake, perhaps none more than Deepak L. Bhatt, MD, MPH, who led both pivotal trials that provide the bulk of sotagliflozin’s evidence package.
In addition to SOLOIST-WHF, Dr. Bhatt also headed the SCORED trial, with 10,584 patients with type 2 diabetes, CKD, and risks for cardiovascular disease randomized to sotagliflozin or placebo and followed for a median of 16 months. The primary result showed that sotagliflozin treatment cut the combined rate of deaths from cardiovascular causes, hospitalizations for heart failure, and urgent visits for heart failure by a significant 26% relative to control patients.
A clear MACE benefit
“The data from SOLOIST-WHF and SCORED look at least as good as the data for the SGLT2 inhibitors for heart failure, and what appears to be different are the rates for MI and stroke in SCORED,” said Dr. Bhatt, director of Mount Sinai Heart, New York.
“I believe the rate of major adverse cardiovascular events [MACE] were reduced [in SCORED], and this is different from the SGLT2 inhibitors,” he said in an interview.
In 2022, Dr. Bhatt reported results from a prespecified secondary analysis of SCORED that showed that treatment with sotagliflozin cut the rate of MACE by a significant 21%-26%, compared with placebo. This finding was, in part, driven by the first data to show a substantial benefit from an SGLT inhibitor on stroke rates.
And while SCORED did not report a significant benefit for slowing progression of CKD, subsequent post hoc analyses have suggested this advantage also in as-yet-unpublished findings, Dr. Bhatt added.
But he said he doubted nephrologists will see it as a first-line agent for slowing CKD progression – an indication already held by dapagliflozin, pending for empagliflozin, and also in place for a third SGLT2 inhibitor, canagliflozin (Invokana) – because sotagliflozin lacks clear significant and prespecified evidence for this effect.
Dr. Bhatt also acknowledged the limitation of sotagliflozin compared with the SGLT2 inhibitors as an agent for glucose control, again because of no evidence for this effect from a prospective analysis and no pending indication for type 2 diabetes treatment. But the SCORED data showed a clear A1c benefit, even in patients with severely reduced renal function.
Mostly for cardiologists? ‘Compelling’ reductions in MIs and strokes
That may mean sotagliflozin “won’t get much use by endocrinologists nor by primary care physicians,” commented Carol L. Wysham, MD, an endocrinologist with MultiCare in Spokane, Wash.
Sotagliflozin “will be a cardiology drug,” and will “have a hard time” competing with the SGLT2 inhibitors, she predicted.
Dr. Bhatt agreed that sotagliflozin “will be perceived as a drug for cardiologists to prescribe. I don’t see endocrinologists, nephrologists, and primary care physicians reaching for this drug if it has a heart failure label.” But, he added, “my hope is that the company files for additional indications. It deserves an indication for glycemic control.”
The evidence for a heart failure benefit from sotagliflozin is “valid and compelling,” and “having this option is great,” commented Mikhail N. Kosiborod, MD, a cardiologist, vice president of research at Saint Luke’s Health System, and codirector of the Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute in Kansas City, Mo. But, he added, “it will be a reasonably tall task for sotagliflozin to come from behind and be disruptive in a space where there are already two well-established SGLT2 inhibitors” approved for preventing heart failure hospitalizations, “with a lot of data to back them up,”
The feature that sets sotagliflozin apart from the approved SGLT2 inhibitors is the “really compelling decrease” it produced in rates of MIs and strokes “that we simply do not see with SGLT2 inhibitors,” Dr. Kosiborod said in an interview.
He also cited results from SCORED that suggest “a meaningful reduction in A1c” when indirectly compared with SGLT2 inhibitors, especially in patients with more severe CKD. The lack of a dedicated A1c-lowering trial or an approved type 2 diabetes indication “will not be a problem for cardiologists,” he predicted, but also agreed that it is less likely to be used by primary care physicians in low-risk patients.
“I can see myself prescribing sotagliflozin,” said Dr. Kosiborod, a SCORED coinvestigator, especially for patients with coexisting type 2 diabetes, heart failure, CKD, and atherosclerotic cardiovascular disease. These patients may get “more bang for the buck” because of a reduced risk for MI and stroke, making sotagliflozin “a solid consideration in these patients if the economic factors align.”
Like others, Dr. Kosiborod cited the big impact pricing will have, especially if, as expected, a generic SGLT2 inhibitor soon comes onto the U.S. market. “Access and affordability are very important.”

Diabetes, cholesterol meds use drops after bariatric surgery
compared with patients with obesity who did not have such an operation. However, these declines didn’t extend to cardiovascular medication use.
“In this study, undergoing bariatric surgery was associated with a substantial and long-lasting reduction in the use of lipid-lowering and antidiabetic medications, compared with no surgery for obesity, while for cardiovascular medications this reduction was only transient,” the authors report in research published in JAMA Surgery.
“The results can aid in informed decision-making when considering bariatric surgery for patients with morbid obesity and inform patients and professionals about the expected long-term effects of medication use for obesity-related comorbidities,” they write.
The study “highlights the benefits of mandated databases that report metabolic bariatric surgery, obesity-related comorbidities, and medications,” writes Paulina Salminen, MD, in an accompanying editorial.
However, key limitations include a lack of weight data, which is important in light of previous studies showing that suboptimal weight loss after bariatric surgery is linked to a higher incidence of type 2 diabetes, dyslipidemia, and hypertension, note Dr. Salminen, of the department of digestive surgery, University Hospital, Turku, Finland, and colleagues.
Swedish, Finnish obesity data probed
When significant weight loss is achieved, bariatric surgery has been well documented to be associated with improvements in a variety of comorbidities, quality of life, and even life expectancy.
Key comorbidities shown to improve with the surgery include hyperlipidemia, cardiovascular disease, and type 2 diabetes.
However, data are lacking on the association between bariatric surgery and the use of medications for those conditions, particularly compared with people with obesity who don’t have bariatric surgery.
To investigate, first author Joonas H. Kauppila, MD, PhD, of Upper Gastrointestinal Surgery, Karolinska University Hospital, Stockholm, and colleagues conducted a population-based cohort study, evaluating data on 26,396 patients who underwent bariatric surgery with gastric bypass or sleeve gastrectomy in Sweden between 2005 and 2020 or Finland between 1995 and 2018.
Overall, 66.4% of patients were women and their median age was 50.
They were compared with five times as many matched controls with obesity who had not had bariatric surgery from the same population databases, representing a total of 131,980 patients who were matched based on age, country, sex, calendar year, and medication use.
In terms of lipid-lowering medication, rates of use after bariatric surgery decreased from 20.3% at baseline to 12.9% after 2 years and bounced back somewhat to 17.6% after 15 years. Comparatively, in the no surgery group, baseline lipid-lowering medication use of 21.0% increased to 44.6% after 15 years, more than twice the rate of usage in the bariatric surgery group in the same period.
Antidiabetic medications were used by 27.7% of patients in the bariatric surgery group at baseline, with a drop to 10.0% after 2 years, followed by an increase to 23.5% after 15 years. In the no surgery group, the rate of antidiabetic medication use steadily increased from 27.7% at baseline to 54.2% after 15 years, which again was nearly double the rate of antidiabetic medication use in the bariatric surgery group at 15 years.
Meanwhile, cardiovascular medications were used by 60.2% of patients receiving bariatric surgery at baseline, with the rate decreasing to 43.2% after 2 years but increasing to 74.6% after 15 years. Among the nonbariatric surgery patients, use of cardiovascular medications increased from 54.4% at baseline to 83.3% after 15 years.
Causes?
As for the cause of the lack of any decline in use of cardiovascular medications versus other medications in the surgery patients, the authors speculate that the effect “may be related to aging and regain of weight over time after bariatric surgery, a phenomenon caused by hormonal, dietary, physical, and behavioral factors.”
“In contrast, as expected, a gradual increase in the use of all three medication groups was observed over time among the patients treated with no surgery for obesity,” they note.
The lower medication use with bariatric surgery can also translate to economic benefits, the authors add.
“Economically, the long-lasting reductions in medication use for hyperlipidemia, cardiovascular morbidity, and diabetes suggest that surgical treatment of morbid obesity may infer savings in medication expenses for patients, health care, and society,” they report.
“Future research may focus on subgroups that are most likely to benefit from bariatric surgery, including resolution and severity of comorbidities,” they continue.
In their editorial, Dr. Salminen and colleagues note that previous research has shown remission of dyslipidemia in up to 70% of patients after bariatric surgery that was independent of weight loss, which appears to support the sustained reduction in lipid-lowering medications following surgery observed in the current study, suggesting some benefits on lipids beyond weight loss.
Other limitations, however, include that the bariatric surgery group in the study was older and had more comorbidities than those in previous bariatric surgery studies.
“Future studies should assess this in a younger cohort with less disease at baseline and differentiation within cardiovascular disease regarding at least hypertension, ischemic heart disease, and heart failure,” the authors conclude.
The authors have reported no relevant financial relationships. Dr. Salminen has reported receiving grants from the Sigrid Jusélius Foundation, Academy of Finland, Government Research Grant Foundation, and the University of Turku (Finland).

“Economically, the long-lasting reductions in medication use for hyperlipidemia, cardiovascular morbidity, and diabetes suggest that surgical treatment of morbid obesity may infer savings in medication expenses for patients, health care, and society,” they report.
“Future research may focus on subgroups that are most likely to benefit from bariatric surgery, including resolution and severity of comorbidities,” they continue.
In their editorial, Dr. Salminen and colleagues note that previous research has shown remission of dyslipidemia in up to 70% of patients after bariatric surgery that was independent of weight loss, which appears to support the sustained reduction in lipid-lowering medications following surgery observed in the current study, suggesting some benefits on lipids beyond weight loss.
Other limitations, however, include that the bariatric surgery group in the study was older and had more comorbidities than those in previous bariatric surgery studies.
“Future studies should assess this in a younger cohort with less disease at baseline and differentiation within cardiovascular disease regarding at least hypertension, ischemic heart disease, and heart failure,” the authors conclude.
The authors have reported no relevant financial relationships. Dr. Salminen has reported receiving grants from the Sigrid Jusélius Foundation, Academy of Finland, Government Research Grant Foundation, and the University of Turku (Finland).

compared with patients with obesity who did not have such an operation. However, these declines didn’t extend to cardiovascular medication use.
“In this study, undergoing bariatric surgery was associated with a substantial and long-lasting reduction in the use of lipid-lowering and antidiabetic medications, compared with no surgery for obesity, while for cardiovascular medications this reduction was only transient,” the authors report in research published in JAMA Surgery.
“The results can aid in informed decision-making when considering bariatric surgery for patients with morbid obesity and inform patients and professionals about the expected long-term effects of medication use for obesity-related comorbidities,” they write.
The study “highlights the benefits of mandated databases that report metabolic bariatric surgery, obesity-related comorbidities, and medications,” writes Paulina Salminen, MD, in an accompanying editorial.
However, key limitations include a lack of weight data, which is important in light of previous studies showing that suboptimal weight loss after bariatric surgery is linked to a higher incidence of type 2 diabetes, dyslipidemia, and hypertension, note Dr. Salminen, of the department of digestive surgery, University Hospital, Turku, Finland, and colleagues.
Swedish, Finnish obesity data probed
When significant weight loss is achieved, bariatric surgery has been well documented to be associated with improvements in a variety of comorbidities, quality of life, and even life expectancy.
Key comorbidities shown to improve with the surgery include hyperlipidemia, cardiovascular disease, and type 2 diabetes.
However, data are lacking on the association between bariatric surgery and the use of medications for those conditions, particularly compared with people with obesity who don’t have bariatric surgery.
To investigate, first author Joonas H. Kauppila, MD, PhD, of Upper Gastrointestinal Surgery, Karolinska University Hospital, Stockholm, and colleagues conducted a population-based cohort study, evaluating data on 26,396 patients who underwent bariatric surgery with gastric bypass or sleeve gastrectomy in Sweden between 2005 and 2020 or Finland between 1995 and 2018.
Overall, 66.4% of patients were women and their median age was 50.
They were compared with five times as many matched controls with obesity who had not had bariatric surgery from the same population databases, representing a total of 131,980 patients who were matched based on age, country, sex, calendar year, and medication use.
In terms of lipid-lowering medication, rates of use after bariatric surgery decreased from 20.3% at baseline to 12.9% after 2 years and bounced back somewhat to 17.6% after 15 years. Comparatively, in the no surgery group, baseline lipid-lowering medication use of 21.0% increased to 44.6% after 15 years, more than twice the rate of usage in the bariatric surgery group in the same period.
Antidiabetic medications were used by 27.7% of patients in the bariatric surgery group at baseline, with a drop to 10.0% after 2 years, followed by an increase to 23.5% after 15 years. In the no surgery group, the rate of antidiabetic medication use steadily increased from 27.7% at baseline to 54.2% after 15 years, which again was nearly double the rate of antidiabetic medication use in the bariatric surgery group at 15 years.
Meanwhile, cardiovascular medications were used by 60.2% of patients receiving bariatric surgery at baseline, with the rate decreasing to 43.2% after 2 years but increasing to 74.6% after 15 years. Among the nonbariatric surgery patients, use of cardiovascular medications increased from 54.4% at baseline to 83.3% after 15 years.
Causes?
As for the cause of the lack of any decline in use of cardiovascular medications versus other medications in the surgery patients, the authors speculate that the effect “may be related to aging and regain of weight over time after bariatric surgery, a phenomenon caused by hormonal, dietary, physical, and behavioral factors.”
“In contrast, as expected, a gradual increase in the use of all three medication groups was observed over time among the patients treated with no surgery for obesity,” they note.
The lower medication use with bariatric surgery can also translate to economic benefits, the authors add.
“Economically, the long-lasting reductions in medication use for hyperlipidemia, cardiovascular morbidity, and diabetes suggest that surgical treatment of morbid obesity may infer savings in medication expenses for patients, health care, and society,” they report.

Younger age of type 2 diabetes onset linked to dementia risk
, new findings suggest.
Moreover, the new data from the prospective Atherosclerosis Risk in Communities (ARIC) cohort also suggest that the previously identified increased risk for dementia among people with prediabetes appears to be entirely explained by the subset who go on to develop type 2 diabetes.
“Our findings suggest that preventing prediabetes progression, especially in younger individuals, may be an important way to reduce the dementia burden,” wrote PhD student Jiaqi Hu of Johns Hopkins University, Baltimore, and colleagues. Their article was published online in Diabetologia.
The result builds on previous findings linking dysglycemia and cognitive decline, the study’s lead author, Elizabeth Selvin, PhD, of the Bloomberg School of Public Health at Johns Hopkins, said in an interview.
“Our prior work in the ARIC study suggests that improving glucose control could help prevent dementia in later life,” she said.
Other studies have also linked higher A1c levels and diabetes in midlife to increased rates of cognitive decline. In addition, Dr. Selvin noted, “There is growing evidence that focusing on vascular health, especially focusing on diabetes and blood pressure, in midlife can stave off dementia in later life.”
This new study is the first to examine the effect of diabetes in the relationship between prediabetes and dementia, as well as the age of diabetes onset on subsequent dementia.
Prediabetes linked to dementia via diabetes development
Of the 11,656 ARIC participants without diabetes at baseline during 1990-1992 (age 46-70 years), 20.0% had prediabetes (defined as A1c 5.7%-6.4% or 39-46 mmol/mol). During a median follow-up of 15.9 years, 3,143 participants developed diabetes. The proportions of patients who developed diabetes were 44.6% among those with prediabetes at baseline versus 22.5% of those without.
Dementia developed in 2,247 participants over a median follow-up of 24.7 years. The cumulative incidence of dementia was 23.9% among those who developed diabetes versus 20.5% among those who did not.
After adjustment for demographics and for the Alzheimer’s disease–linked apolipoprotein E (APOE) gene, prediabetes was significantly associated with incident dementia (hazard ratio [HR], 1.19). However, significance disappeared after adjustment for incident diabetes (HR, 1.09), the researchers reported.
Younger age at diabetes diagnosis raises dementia risk
Age at diabetes diagnosis made a difference in dementia risk. With adjustments for lifestyle, demographic, and clinical factors, those diagnosed with diabetes before age 60 years had a nearly threefold increased risk for dementia compared with those who never developed diabetes (HR, 2.92; P < .001).
The dementia risk was also significantly increased, although to a lesser degree, among those aged 60-69 years at diabetes diagnosis (HR, 1.73; P < .001) and age 70-79 years at diabetes diagnosis (HR, 1.23; P < .001). The relationship was not significant for those aged 80 years and older (HR, 1.13).
“Prevention efforts in people with diabetes diagnosed younger than 65 years should be a high priority,” the authors urged.
Taken together, the data suggest that prolonged exposure to hyperglycemia plays a major role in dementia development.
“Putative mechanisms include acute and chronic hyperglycemia, glucose toxicity, insulin resistance, and microvascular dysfunction of the central nervous system. ... Glucose toxicity and microvascular dysfunction are associated with increased inflammatory and oxidative stress, leading to increased blood–brain permeability,” the researchers wrote.
Dr. Selvin said that her group is pursuing further work in this area using continuous glucose monitoring. “We plan to look at ... how glycemic control and different patterns of glucose in older adults may be linked to cognitive decline and other neurocognitive outcomes.”
The researchers reported no relevant financial relationships. Dr. Selvin has reported being on the advisory board for Diabetologia; she had no role in peer review of the manuscript.
