Though many people remain on the fence about getting the latest COVID vaccine booster, new research suggests a strong argument for getting the shot this winter: It sharply reduces the risk for COVID. 

Researchers found that getting vaccinated led to a 69% reduction in long-COVID risk among adults who received three vaccines before being infected. The risk reduction was 37% for those who received two doses. Experts say the research provides a strong argument for getting the vaccine, noting that about 10% of people infected with COVID go on to have long COVID, which can be debilitating for one quarter of those with long-lasting symptoms.

The data come from a systematic literature review and meta-analysis published in October in Antimicrobial Stewardship & Epidemiology. Researchers examined 32 studies published between December 2019 and June 2023, involving 775,931 adults. Twenty-four studies, encompassing 620,221 individuals, were included in the meta-analysis. 

“The body of evidence from all these different studies converge on one single reality — that vaccines reduce the risk of long COVID, and people who keep up to date on their vaccinations also fared better than people who got it once or twice and didn’t follow up,” said Ziyad Al-Aly, MD, a clinical epidemiologist at Washington University in St Louis. 

Researchers have reported similar results for children. The National Institutes of Health RECOVER Initiative team found that vaccines are up to 42% effective in preventing long COVID in children, said Dr. Carlos Oliveira, MD, a pediatric infectious diseases specialist and Yale researcher who contributed to the study, which is in preprint. 

Vaccines also protect children from multisystem inflammatory syndrome, a condition that can happen after COVID, as well as protect against other COVID-related problems, such as missed school days, Oliveira said. “Even if the vaccine doesn’t completely stop long COVID, it’s still good for kids to get vaccinated for all these other reasons.” 

However, uptake for the latest boosters has been slow: the Centers for Disease Control and Prevention reported that by mid-November, less than 16% of people aged 18 years or older had received a shot. For children, the number was closer to 6%. A recent Kaiser Family Foundation survey found that booster rates for adults are similar to what it was 1 year ago. 

The survey results suggest that people are no longer as worried about COVID, which is why there is less concerned about keeping up with boosters. Though the current mutation of the virus is not as debilitating as its predecessors, long COVID continues to be a problem: as of January 2023, 28% of people who had contracted the virus had experienced long-COVID symptoms. And though the mechanisms are still not fully understood, and researchers have yet to agree on a definition of long COVID, they are certain about this much: The best way to avoid it is to avoid getting infected to begin with. 

The lack of a diagnostic test for long COVID and the fact that the symptoms mimic those of other diseases lead to inconsistency that can make studies hard to replicate. In the papers reviewed for the Antimicrobial Stewardship & Epidemiology study, long COVID was defined as having symptoms lasting from more than 4 weeks to more than 6 months. Alexandre Marra, MD, the lead author and a researcher at the Hospital Israelita Albert Einstein, in São Paulo, Brazil, and at the University of Iowa, said that a clear standard definition is needed to better understand the actual prevalence and evaluate vaccine effectiveness. 

Al-Aly noted that there is a logical explanation for one finding in the paper: The percentage of individuals who had COVID and reported that long-COVID symptoms declined from 19% in June 2022 to 11% in January 2023. 

Because a pandemic is a dynamic event, constantly producing different variants with different phenotypes, the prevalence of disease is naturally going to be affected. “People who got infected early in the pandemic may have a different long COVID profile and long COVID risk than people who got infected in the second or third year of the pandemic,” Al-Aly said. 

Most of the studies reported data from before the Omicron-variant era. Only eight reported data during that era. Omicron was not as lethal as previous variants, and consequently, fewer patients developed long COVID during that time. 

One of those who did is Yeng Chang, age 40 years, a family doctor who lives in Sherwood Park, Alberta, Canada. Chang developed long COVID during fall 2022 after getting the virus in June. By then, she’d been vaccinated three times, but she isn’t surprised that she got sick because each vaccine she had was developed before Omicron.

“When I had COVID I was really sick, but I was well enough to stay home,” she said. “I think if I didn’t have my immunizations, I might have been hospitalized, and I don’t know what would have happened.” 

Long COVID has left Chang with brain fog, fatigue, and a lack of physical stamina that forced her to pause her medical practice. For the past year and a half, she’s spent more time as a patient than a physician. 

Chang had her fifth COVID vaccination in the fall and recommends that others do the same. “The booster you got however many years ago was effective for the COVID of that time but there is a new COVID now. You can’t just say, ‘I had one and I’m fine forever.’”

Long-term data showed negligible differences in mortality among hypertensive adults treated with thiazide-type diuretics, calcium channel blockers, or angiotensin-converting enzyme inhibitors in a review of nearly 33,000 individuals published in JAMA Network Open.

The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) study was designed to compare initial antihypertensive treatments with a calcium channel blocker (CCB; amlodipine), an angiotensin-converting enzyme (ACE) inhibitor (lisinopril) or an alpha-blocker (doxazosin), and a thiazide-type diuretic (chlorthalidone).

The composite primary outcome was fatal coronary heart disease (CHD) or nonfatal myocardial infarction (MI), but long-term data were lacking, wrote Jose-Miguel Yamal, PhD, of University of Texas Health Science Center at Houston, and colleagues. A previous study with 8-13 years of follow-up showed no significant differences in mortality between the treatment groups, the researchers noted.

In the current study, a prespecified secondary analysis of ALLHAT, the researchers added 11 more years of data for a total of 19-24 years of follow-up after randomization.

In the original ALLHAT, 32,804 adults aged 55 years and older with a diagnosis of hypertension and at least one additional coronary heart disease risk factor were followed for 4-8 years for all-cause mortality. A subgroup of 22,754 were followed for fatal or nonfatal cardiovascular disease (CVD) for a mean of 13.7 years, with a maximum of 23.9 years.

The study occurred from Feb. 23, 1994, to Dec. 31, 2017. The participants were randomized to receive a thiazide-type diuretic (15,002 patients), a CCB (8,898 patients), or an ACE inhibitor (8,904 patients).

The primary outcome was CVD mortality; secondary outcomes included all-cause mortality, combined fatal and nonfatal CVD (CVD morbidity), and both morbidity and mortality for coronary heart disease, stroke, heart failure, end-stage renal disease, and cancer.

At 23 years, CVD mortality rates per 100 persons were 23.7, 21.6, and 23.8 in the diuretic, CCB, and ACE inhibitor groups, respectively. The adjusted hazard ratios were 0.97 for CCB vs. diuretics and 1.06 for ACE inhibitors vs. diuretics.

Although the risk of stroke mortality and of combined fatal and nonfatal hospitalized stroke was higher in the ACE inhibitor group compared with the diuretic group (adjusted hazard ratios 1.19 and 1.11, respectively), this increase was no longer significant after adjustment for multiple comparisons. “In contrast to the in-trial and 8-year to 13-year analyses, we now observed that the lisinopril group had an increased risk of kidney disease mortality that emerged after approximately 13 years after randomization, but this effect was attenuated after adjustment for baseline variables,” the researchers wrote in their discussion.

The findings were limited by several factors including the potential effect of unblinding if participants stopped the randomized drug, and by the lack of morbidity and mortality data on Canadian participants, Veterans Affairs participants, and those with no Medicare number, the researchers noted. Other limitations included the lack of data on posttrial medication use, blood pressure, and laboratory findings, they said.

However, the results over the follow-up period of up to 23 years supported those of the larger ALLHAT study, with similar outcomes among the drugs, and with 11 years of passive follow-up, “the results for lisinopril vs. chlorthalidone for stroke and stroke mortality are almost the same,” they concluded.
 

Findings support current practice, but new drug data are needed

The current study was important to determine whether there was a significant difference in long-term morbidity and mortality between patients treated with thiazide diuretics, calcium channel blockers and ACE inhibitors, Noel Deep, MD, said in an interview.

“Previously reported data had indicated no significant differences between patients randomized to one of these three classes of antihypertensive medications during the trial period or at 8-13 years post trial,” said Dr. Deep, a general internist in private practice in Antigo, Wisc., who was not involved in the study. Dr. Deep is chief medical officer and a staff physician at Aspirus Langlade Hospital in Antigo.

“This study reinforces the previously noted benefits of the three classes of antihypertensive medications, as well as the higher rates of cardiovascular disease and stroke in the ACE inhibitor arm,” he said.

In clinical practice, the results suggest that thiazide diuretics should be considered first-line agents for management of hypertension based on their noninferiority compared with ACE inhibitors and CCBs, and lower risk of stroke compared with ACE inhibitors, Dr. Deep said in an interview. “All three classes of antihypertensive medications are equally efficacious in blood pressure control and preventing all-cause mortality,” he said.

More research is needed in the wake of the introduction of other classes of antihypertensives since the original ALLHAT trial, Dr. Deep said. “It would be beneficial to assess the relative benefit/risks of those medications compared to the thiazide diuretics, and I would also look at studies comparing beta blockers to the thiazide diuretics,” he said. The question remains as to whether outcomes were affected by patients’ use of other classes of antihypertensives after the trial period, he said.

The study was supported by the National Institute on Aging of the National Institutes of Health. The researchers had no financial conflicts to disclose. Dr. Deep had no financial conflicts to disclose and serves on the editorial advisory board of Internal Medicine News.

Patients receiving semaglutide for weight loss show a significantly higher rate of continuing the medication at 1 year compared with less effective anti-obesity drugs. However, even among those patients, continuation declines to fewer than half of patients.

“We now have effective US Food and Drug Administration–approved anti-obesity medications; [however], this study shows that in a real-world setting, the vast majority of patients discontinued their prescription fills within the first year,” said first author Hamlet Gasoyan, PhD, lead author of the study and a researcher with Cleveland Clinic’s Center for Value-Based Care Research, said in a press statement.

The study was published online in the journal Obesity.

While breakthrough drugs such as glucagon-like peptide-1 (GLP-1) receptor agonists have shown high efficacy in achieving weight loss while providing a host of other health benefits, their discontinuation has been shown to potentially result in a rapid regaining of weight that was lost, as well as a reversal of the other health benefits, such as cardiometabolic improvements, the study authors wrote.

To evaluate rates of persistence with those along with other weight loss medications and factors associated with discontinuation, Dr. Gasoyan and colleagues conducted a retrospective cohort study, identifying 1911 patients with obesity, who had an initial anti-obesity medication prescription filled between 2015 and 2022 at Cleveland Clinic centers in Ohio and Florida. 

Over the study period, 25% of patients filled a prescription for semaglutide, 34% for naltrexone-bupropion, 26% for phentermine-topiramate, 14% for liraglutide, and 0.9% for orlistat.

The patients had a median baseline BMI of 38, with obesity defined as a BMI of 30 or higher.
 

Medication Continuation Drops After 3 Months

With a median follow-up time of 2.4 years, the rate of persistence to the medications overall dropped from 44% at 3 months to 33% at 6 months and just 19% at 12 months. 

In a multivariate analysis, semaglutide was associated with the highest odds of 1-year persistence (adjusted odds ratio [AOR], 4.26), while naltrexone-bupropion had the lowest odds (AOR, 0.68), compared with phentermine-topiramate. The other agents did not have significantly different odds of persistence.

Semaglutide and liraglutide also had the highest persistence rates overall, including at 3 months (63% and 52%, respectively) and 6 months (56% and 37%, respectively).

Those with higher weight loss at 6 months had a higher likelihood of remaining on the weight loss medication at 1 year, with a 1% increase in weight loss at 6 months associated with 6% increased odds of still being persistent at year 1 (adjusted odds ratio, 1.06).

Those who did continue medications at 1 year had a mean of 10% weight loss at 12 months compared with just 2% among individuals who were not persistent (P <.001).

Most patients (84%) in the study were privately insured, and weight loss drug adherence varied significantly based on the insurance carrier. 

Studies demonstrating the effects of discontinuing treatment with semaglutide include the STEP 1 trial extension, which showed that 1 year after discontinuation of treatment and lifestyle intervention, participants regained two thirds of their lost weight on average, and the cardiometabolic improvements with the weight loss were reversed.

In light of those findings, “the current scientific knowledge favors using anti-obesity medications longer term for weight loss maintenance if they are well-tolerated and have resulted in clinically meaningful weight loss,” Dr. Gasoyan told this news organization. 

Paradoxically, the possible regaining of weight could be a factor in some insurers denying longer-term coverage, he noted.
 

Discontinuing Medications Means Regaining Appetite

Anne Peters, MD, a professor of medicine at USC’s Keck School of Medicine in Los Angeles and director of the USC Clinical Diabetes Programs, underscored that the possibility of regaining weight with discontinuation of GLP-1 receptor agonists is indeed “a big concern because your appetite comes back in spades when you take away the effect of these hormones,” she told this news organization. “For that reason, I don’t ever tell people to stop cold turkey.”

Regarding the question of how long patients should remain on the medications, Peters said the scenario might be compared to the need for patients with type 1 diabetes to be on insulin, which is a gut hormone.

“These medications are also gut hormones, and some patients may need to also be on them for life to maintain the benefits,” she said. 

“If a patient for some reason wishes to come off of the medication, for instance in order to be on less medicine, I have them titrate down and usually there will be a dose where they actually need only a small dose.

“I even have some patients who just take semaglutide once a month who are able to manage to maintain their weight loss,” Dr. Peters noted. 

“But the whole goal in people who are overweight or obese is to establish a new set point and maintain whatever that new target weight is.”

Dr. Peters agreed that the loss of insurance coverage for the medications can throw a big wrench into that maintenance, presenting adverse effects of its own by causing a lack of treatment continuity. 

“When you lose weight, you lose lean body mass and fat mass, but when you regain, it’s primary fat mass, so if you go on and off these drugs, it can contribute to a loss of lean mass. Therefore, these drugs should not be taken if someone is going to go on and off them repeatedly.” 

The study received funding from the National Cancer Institute. Dr. Peters has consulted for Eli Lilly in the past.

Patients receiving semaglutide for weight loss show a significantly higher rate of continuing the medication at 1 year compared with less effective anti-obesity drugs. However, even among those patients, continuation declines to fewer than half of patients.

“We now have effective US Food and Drug Administration–approved anti-obesity medications; [however], this study shows that in a real-world setting, the vast majority of patients discontinued their prescription fills within the first year,” said first author Hamlet Gasoyan, PhD, lead author of the study and a researcher with Cleveland Clinic’s Center for Value-Based Care Research, said in a press statement.

The study was published online in the journal Obesity.

While breakthrough drugs such as glucagon-like peptide-1 (GLP-1) receptor agonists have shown high efficacy in achieving weight loss while providing a host of other health benefits, their discontinuation has been shown to potentially result in a rapid regaining of weight that was lost, as well as a reversal of the other health benefits, such as cardiometabolic improvements, the study authors wrote.

To evaluate rates of persistence with those along with other weight loss medications and factors associated with discontinuation, Dr. Gasoyan and colleagues conducted a retrospective cohort study, identifying 1911 patients with obesity, who had an initial anti-obesity medication prescription filled between 2015 and 2022 at Cleveland Clinic centers in Ohio and Florida. 

Over the study period, 25% of patients filled a prescription for semaglutide, 34% for naltrexone-bupropion, 26% for phentermine-topiramate, 14% for liraglutide, and 0.9% for orlistat.

The patients had a median baseline BMI of 38, with obesity defined as a BMI of 30 or higher.
 

Medication Continuation Drops After 3 Months

With a median follow-up time of 2.4 years, the rate of persistence to the medications overall dropped from 44% at 3 months to 33% at 6 months and just 19% at 12 months. 

In a multivariate analysis, semaglutide was associated with the highest odds of 1-year persistence (adjusted odds ratio [AOR], 4.26), while naltrexone-bupropion had the lowest odds (AOR, 0.68), compared with phentermine-topiramate.

TOPLINE: 

Compared with a healthy omnivore diet, a healthy vegan diet led to significant improvement in  low-density lipoprotein cholesterol (LDL-C) as well as fasting insulin and weight loss in a randomized controlled trial of identical twins. 

METHODOLOGY:  

• Researchers randomly assigned 22 pairs of healthy adult identical twins (34 women, mean age 39 years, mean body mass index 25.9) to a healthy vegan or omnivore diet (1 twin per pair) for 8 weeks.
• For the first 4 weeks, diet-specific meals were provided via a meal delivery service. For the final 4 weeks, participants prepared their own diet-appropriate meals/snacks.
• The primary outcome was change in LDL-C; secondary outcomes included changes in body weight and fasting insulin. 

TAKEAWAY:

• After 8 weeks, twins eating a vegan diet showed a significant mean decrease of 13.9 mg/dL in LDL-C compared with twins eating an omnivorous diet.
• The vegan diet also led to a significant mean decrease of 2.9 Times New RomanμIU/mL in fasting insulin and 1.9 kg in body weight after 8 weeks compared with the omnivore diet, although weight loss was observed in both diet groups. 
• The vegan diet group also had a larger but nonsignificant absolute median decrease in fasting HDL-C  triglycerides , vitamin B12, glucose, and trimethylamine N-oxide levels at 8 weeks.

IN PRACTICE: 

“Our results corroborate a previous finding showing that eating a vegan diet can improve cardiovascular health. Clinicians may consider recommending plant-based diets to reduce cardiometabolic risk factors, as well as aligning with environmental benefits,” the researchers concluded. 

SOURCE: 

The study, with first author Matthew J. Landry, PhD, RDN, Stanford Prevention Research Center, Stanford University School of Medicine, California, was published online November 30 in  JAMA Network Open. 

LIMITATIONS: 

The adult twin population was generally healthy and findings may not be generalizable to other populations. The sample size was small, and the duration of intervention was short and there was no follow-up period, which limits insights on stability and sustainability of the diets. 

DISCLOSURES: 

Funding was provided by the Vogt Foundation, and grants from Stanford University and the National Heart, Lung, and Blood Institute. Dr. Landry has no relevant disclosures. One author reported receiving funding from Beyond Meat outside of this study.

PHILADELPHIA — Promise that the unmet need for more effective pulmonary artery hypertension treatments may soon be met was in strong evidence in research into three strategies presented at this year’s recent American Heart Association scientific sessions; one was based on an ancient Chinese herb epimedium (yin yang huo or horny goat weed) commonly used for treating sexual dysfunction and directly related to the phosphodiesterase inhibitors sildenafil, vardenafil, and tadalafil (sold as Viagra, Levitra, and Cialis). A second studied sotatercept, an investigational, potential first-in-class activin signaling inhibitor biologic, and a third evaluated physically ablating the baroreceptor nerves that stimulate vasoconstriction of the pulmonary artery via catheter-based techniques.

Until as recently as the late 1970s, a pulmonary arterial hypertension diagnosis was a uniformly fatal one.¹ While targeted therapies have since improved prognosis, pulmonary arterial hypertension remains a chronic and progressive disorder of the pulmonary vasculature with significant morbidity and mortality associated with pulmonary and right ventricle remodeling, and leads toward heart failure and death. The complex underlying pathogenesis was divided into six groups by the 6th World Symposium on Pulmonary Hypertension (WSPH) in 2018, and includes as its most common features pulmonary artery endothelial cell dysfunction, pulmonary artery smooth muscle cell proliferation and migration, and dysregulated fibroblast activity leading to dysregulated vasoconstriction, micro and in-situ vascular thrombosis, vascular fibrosis and pathogenic remodeling of pulmonary vessels.¹ The threshold mean arterial pressure (mPAP) for pulmonary arterial hypertension was defined by the 6th [WSPH] at mPAP ≥ 20 mm Hg, twice the upper limit of a normal mPAP of 14.0 ± 3.3 mm Hg as reported by Kovacs et al. in 2018.²

Pathways for current therapies

Current drugs for pulmonary arterial hypertension focus on three signaling pathways, including the endothelin receptor, prostacyclin and nitric oxide pathways, stated Zhi-Cheng Jing, MD, professor of medicine, head of the cardiology department at Peking Union Medical College Hospital, Peking, China. While the phosphodiesterase 5 inhibitors sildenafil and tadalafil, which target the nitric oxide pathway, came into wide use after Food and Drug Administration approval, the need for higher PDE5-selectivity remains, Dr. Jing said. Structurally modified from the active ingredient in epimedium, TPN171H is an investigational PDE5 inhibitor which has shown several favorable features: a greater PDE5 selectivity than both sildenafil and tadalafil in vitro, an ability to decrease right ventricular systolic pressure and alleviate arterial remodeling in animal studies, and safety and tolerability in healthy human subjects.

The current randomized, double-blind, placebo-and active-controlled phase IIa study assessed the hemodynamic impact of a single oral dose of TPN171H in 60 pulmonary arterial hypertension patients (mean age ~34 years, 83.3% female), all with negative vasodilation test results and in WHO class 2 or 3. Only patients aged 18-75 years with group 1 pulmonary arterial hypertension of idiopathic, connective tissue disorder, or repaired congenital heart defects etiology were included. Patients were divided into six groups: placebo, TPN171H at 2.5, 5, and 10 milligrams, and tadalafil at 20 and 40 milligrams.

For the primary endpoint of maximum decrease in pulmonary vascular resistance (PVR), significant reductions vs. placebo were found only for the TPN171H 5-mg group (–41.2% vs. –24.4%; P = .008) and for the 20-mg (–39.8%) and 40-mg (–37.6%) tadalafil groups (both P < .05). What was not seen in the tadalafil groups, but was evident in the TPN171H 5-mg group, was a significant reduction in the secondary endpoint of PVR/SVR (systolic vascular resistance) at 2, 3, and 5 hours (all P < .05). “As we know,” Dr. Jing said in an interview, “the PDE5 inhibitor functions as a vasodilator, having an impact on both pulmonary circulation and systemic circulation. So, to evaluate the  selectivity for pulmonary circulation is crucial when exploring a novel drug for pulmonary arterial hypertension. The change of PVR/SVR ratio from baseline is an indicator for selectivity for pulmonary circulation and implies that TPN171H has good PDE5 selectivity in the pulmonary vasculature,” Dr. Jing said.

TPN171H was well tolerated with no serious adverse effects (vomiting 10% and headache 10% were most common with no discontinuations).
 

TGF-signaling pathway

A meta-analysis of randomized controlled trials of sotatercept, an investigational fusion protein under priority FDA review that modulates the TGF-beta superfamily signaling pathway, looked at PVR, pulmonary arterial pressure (PAP), right arterial pressure (RAP) and N-terminal pro-brain natriuretic peptide (NT-proBNP). A literature search by corresponding author Vamsikalyan Borra, MD, Knapp Medical Center, Weslaco, Texas, and colleagues identified two trials (STELLAR and PULSAR) comprising 429 patients with pulmonary arterial hypertension. The experimental arms (sotatercept) had 237 patients (mean age ~49 years, ~82% female) and the placebo arm had 192 patients (mean age ~47 years, ~80% female).

A pooled analysis showed significant reductions with sotatercept in PVR (standardization mean difference [SMD] = –1.00, 95% confidence interval [CI] = –1.2, –.79, P < .001), PAP (SMD = –1.34, 95% CI = 1.6, –1.08, P < .001), RAP (SMD = –0.66, 95% CI = –0.93, –0.39, P < .001), and the levels of NT-proBNP (SMD = –0.64, 95% CI = –1.01, –0.27, P < .001) at 24 weeks from baseline. The sotatercept safety profile was favorable, with lower overall incidence of adverse events (84.8% vs. 87.5%) and fewer adverse events leading to death (0.4% vs. 3.1%) compared with placebo. Further investigation is needed, however, according to Dr. Borra, into the higher frequency of reported thrombocytopenia (71.7% vs. 20.8%) with sotatercept. “Our findings,” Dr. Borra said in a poster session, “suggest that sotatercept is an effective treatment option for pulmonary arterial hypertension, with the potential to improve both pulmonary and cardiac function.”
 

Denervation technique

Catheter-based ablation techniques, most commonly using thermal energy, target the afferent and efferent fibers of the baroreceptor reflex in the main pulmonary artery trunk and bifurcation involved in elevated pulmonary artery pressure. Mounica Vorla, MD, Carle Foundation Hospital, Urbana, Illinois, and colleagues conducted an updated systematic review and meta-analysis of the safety and efficacy of pulmonary artery denervation (PADN) for pulmonary arterial hypertension in seven clinical trials with 506 patients with moderate-severe pulmonary arterial hypertension conducted from 2013 to 2022.

Compared with placebo, PADN treatment was associated with a significant reduction in mean pulmonary artery pressure (weighted mean difference [WMD] = –6.9 mm Hg; 95% CI = –9.7, –4.1; P < .01; I2 = 61) and pulmonary vascular resistance (WMD = –3.2; 95% CI = –5.4, –0.9; P = .005). PADN improvements in cardiac output were also statistically significant (WMD = 0.3; 95% CI = 0.07, 0.6; P = .012), with numerical improvement in 6-minute walking distance (WMD = 67.7; 95% CI = –3.73, 139.2; P = .06) in the PADN group. Side effects were less common in the PADN group as compared with the placebo group, Dr. Vorla reported. She concluded, “This updated meta-analysis supports PADN as a safe and efficacious therapy for severe pulmonary arterial hypertension.” The authors noted limitations imposed by the small sample size, large data heterogeneity, and medium-quality literature. Larger randomized, controlled trials with clinical endpoints comparing PADN with optimal medical therapy are needed, they stated.

For the primary endpoint of maximum decrease in pulmonary vascular resistance (PVR), significant reductions vs. placebo were found only for the TPN171H 5-mg group (–41.2% vs. –24.4%; P = .008) and for the 20-mg (–39.8%) and 40-mg (–37.6%) tadalafil groups (both P < .05). What was not seen in the tadalafil groups, but was evident in the TPN171H 5-mg group, was a significant reduction in the secondary endpoint of PVR/SVR (systolic vascular resistance) at 2, 3, and 5 hours (all P < .05). “As we know,” Dr. Jing said in an interview, “the PDE5 inhibitor functions as a vasodilator, having an impact on both pulmonary circulation and systemic circulation. So, to evaluate the  selectivity for pulmonary circulation is crucial when exploring a novel drug for pulmonary arterial hypertension. The change of PVR/SVR ratio from baseline is an indicator for selectivity for pulmonary circulation and implies that TPN171H has good PDE5 selectivity in the pulmonary vasculature,” Dr. Jing said.

TPN171H was well tolerated with no serious adverse effects (vomiting 10% and headache 10% were most common with no discontinuations).
 

TGF-signaling pathway

A meta-analysis of randomized controlled trials of sotatercept, an investigational fusion protein under priority FDA review that modulates the TGF-beta superfamily signaling pathway, looked at PVR, pulmonary arterial pressure (PAP), right arterial pressure (RAP) and N-terminal pro-brain natriuretic peptide (NT-proBNP). A literature search by corresponding author Vamsikalyan Borra, MD, Knapp Medical Center, Weslaco, Texas, and colleagues identified two trials (STELLAR and PULSAR) comprising 429 patients with pulmonary arterial hypertension. The experimental arms (sotatercept) had 237 patients (mean age ~49 years, ~82% female) and the placebo arm had 192 patients (mean age ~47 years, ~80% female).

A pooled analysis showed significant reductions with sotatercept in PVR (standardization mean difference [SMD] = –1.00, 95% confidence interval [CI] = –1.2, –.79, P < .001), PAP (SMD = –1.34, 95% CI = 1.6, –1.08, P < .001), RAP (SMD = –0.66, 95% CI = –0.93, –0.39, P < .001), and the levels of NT-proBNP (SMD = –0.64, 95% CI = –1.01, –0.27, P < .001) at 24 weeks from baseline. The sotatercept safety profile was favorable, with lower overall incidence of adverse events (84.8% vs. 87.5%) and fewer adverse events leading to death (0.4% vs. 3.1%) compared with placebo. Further investigation is needed, however, according to Dr. Borra, into the higher frequency of reported thrombocytopenia (71.7% vs. 20.8%) with sotatercept. “Our findings,” Dr. Borra said in a poster session, “suggest that sotatercept is an effective treatment option for pulmonary arterial hypertension, with the potential to improve both pulmonary and cardiac function.”
 

Denervation technique

Catheter-based ablation techniques, most commonly using thermal energy, target the afferent and efferent fibers of the baroreceptor reflex in the main pulmonary artery trunk and bifurcation involved in elevated pulmonary artery pressure. Mounica Vorla, MD, Carle Foundation Hospital, Urbana, Illinois, and colleagues conducted an updated systematic review and meta-analysis of the safety and efficacy of pulmonary artery denervation (PADN) for pulmonary arterial hypertension in seven clinical trials with 506 patients with moderate-severe pulmonary arterial hypertension conducted from 2013 to 2022.

Compared with placebo, PADN treatment was associated with a significant reduction in mean pulmonary artery pressure (weighted mean difference [WMD] = –6.9 mm Hg; 95% CI = –9.7, –4.1; P < .01; I2 = 61) and pulmonary vascular resistance (WMD = –3.2; 95% CI = –5.4, –0.9; P = .005). PADN improvements in cardiac output were also statistically significant (WMD = 0.3; 95% CI = 0.07, 0.6; P = .012), with numerical improvement in 6-minute walking distance (WMD = 67.7; 95% CI = –3.73, 139.2; P = .06) in the PADN group. Side effects were less common in the PADN group as compared with the placebo group, Dr. Vorla reported. She concluded, “This updated meta-analysis supports PADN as a safe and efficacious therapy for severe pulmonary arterial hypertension.” The authors noted limitations imposed by the small sample size, large data heterogeneity, and medium-quality literature. Larger randomized, controlled trials with clinical endpoints comparing PADN with optimal medical therapy are needed, they stated.

PHILADELPHIA — Promise that the unmet need for more effective pulmonary artery hypertension treatments may soon be met was in strong evidence in research into three strategies presented at this year’s recent American Heart Association scientific sessions; one was based on an ancient Chinese herb epimedium (yin yang huo or horny goat weed) commonly used for treating sexual dysfunction and directly related to the phosphodiesterase inhibitors sildenafil, vardenafil, and tadalafil (sold as Viagra, Levitra, and Cialis). A second studied sotatercept, an investigational, potential first-in-class activin signaling inhibitor biologic, and a third evaluated physically ablating the baroreceptor nerves that stimulate vasoconstriction of the pulmonary artery via catheter-based techniques.

Until as recently as the late 1970s, a pulmonary arterial hypertension diagnosis was a uniformly fatal one.¹ While targeted therapies have since improved prognosis, pulmonary arterial hypertension remains a chronic and progressive disorder of the pulmonary vasculature with significant morbidity and mortality associated with pulmonary and right ventricle remodeling, and leads toward heart failure and death. The complex underlying pathogenesis was divided into six groups by the 6th World Symposium on Pulmonary Hypertension (WSPH) in 2018, and includes as its most common features pulmonary artery endothelial cell dysfunction, pulmonary artery smooth muscle cell proliferation and migration, and dysregulated fibroblast activity leading to dysregulated vasoconstriction, micro and in-situ vascular thrombosis, vascular fibrosis and pathogenic remodeling of pulmonary vessels.¹ The threshold mean arterial pressure (mPAP) for pulmonary arterial hypertension was defined by the 6th [WSPH] at mPAP ≥ 20 mm Hg, twice the upper limit of a normal mPAP of 14.0 ± 3.3 mm Hg as reported by Kovacs et al. in 2018.²

Pathways for current therapies

Current drugs for pulmonary arterial hypertension focus on three signaling pathways, including the endothelin receptor, prostacyclin and nitric oxide pathways, stated Zhi-Cheng Jing, MD, professor of medicine, head of the cardiology department at Peking Union Medical College Hospital, Peking, China. While the phosphodiesterase 5 inhibitors sildenafil and tadalafil, which target the nitric oxide pathway, came into wide use after Food and Drug Administration approval, the need for higher PDE5-selectivity remains, Dr. Jing said. Structurally modified from the active ingredient in epimedium, TPN171H is an investigational PDE5 inhibitor which has shown several favorable features: a greater PDE5 selectivity than both sildenafil and tadalafil in vitro, an ability to decrease right ventricular systolic pressure and alleviate arterial remodeling in animal studies, and safety and tolerability in healthy human subjects.

The current randomized, double-blind, placebo-and active-controlled phase IIa study assessed the hemodynamic impact of a single oral dose of TPN171H in 60 pulmonary arterial hypertension patients (mean age ~34 years, 83.3% female), all with negative vasodilation test results and in WHO class 2 or 3. Only patients aged 18-75 years with group 1 pulmonary arterial hypertension of idiopathic, connective tissue disorder, or repaired congenital heart defects etiology were included. Patients were divided into six groups: placebo, TPN171H at 2.5, 5, and 10 milligrams, and tadalafil at 20 and 40 milligrams.

For the primary endpoint of maximum decrease in pulmonary vascular resistance (PVR), significant reductions vs. placebo were found only for the TPN171H 5-mg group (–41.2% vs. –24.4%; P = .008) and for the 20-mg (–39.8%) and 40-mg (–37.6%) tadalafil groups (both P < .05). What was not seen in the tadalafil groups, but was evident in the TPN171H 5-mg group, was a significant reduction in the secondary endpoint of PVR/SVR (systolic vascular resistance) at 2, 3, and 5 hours (all P < .05). “As we know,” Dr. Jing said in an interview, “the PDE5 inhibitor functions as a vasodilator, having an impact on both pulmonary circulation and systemic circulation.

In a letter dated Nov. 30, 2023, the Food and Drug Administration informed isotretinoin manufacturers that they have 6 months to make five changes to existing iPLEDGE Risk Evaluation and Mitigation Strategy (REMS) requirements for the acne drug isotretinoin.

The development follows a March 2023 joint meeting of the FDA’s Drug Safety and Risk Management Advisory Committee and the Dermatologic and Ophthalmic Drugs Advisory Committee about iPLEDGE REMS requirements, which included feedback from patients and dermatologists and recommendations for changes to the REMS program, aimed at minimizing the burden of the program on patients, pharmacies, and prescribers while continuing to maintain safe use of the highly teratogenic drug for patients.

The five changes include the following:

• Remove the requirement that pregnancy tests must be performed in a specially certified (i.e., Clinical Laboratory Improvement Amendments [CLIA]) laboratory. In the opinion of John S. Barbieri, MD, MBA, director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, Boston, this change “may make it easier to perform pregnancy tests in a clinic setting without needing to send the patient to a separate lab,” he said in an interview.
• Allow prescribers the option of using home pregnancy testing for their patients during and after isotretinoin treatment. Prescribers who rely on the patient to perform a home pregnancy test need to take steps to minimize patients falsifying the results of these tests. According to Dr. Barbieri, this means that two pregnancy tests prior to starting isotretinoin must be done in a lab or office setting. “However, all the pregnancy tests on therapy can be either in a medical setting or using a home pregnancy test,” he told this news organization. “This option facilitates the use of telemedicine so that patients would not need to come in; they can just share a pregnancy test with their name and date with their dermatologist.”
• Remove the waiting period requirement — also known as the “19-day lockout” — for patients if they do not obtain isotretinoin within the first 7-day prescription window. According to Dr. Barbieri, this change helps to ensure that patients can begin isotretinoin in a timely manner. “Insurance and pharmacy delays that are no fault of the patient can commonly cause missed initial window periods,” he said. “Allowing for immediate repeat of a pregnancy test to start a new window period, rather than requiring the patient to wait 19 more days, can ensure patient safety and pregnancy prevention without negatively impacting access.”
• Revise the pregnancy registry requirement to remove the objective to document the pregnancy and fetal outcomes for each pregnancy.
• Revise the requirement for prescribers to document patient counseling in patients who cannot become pregnant from monthly to only at enrollment. Dr. Barbieri characterized this change as “major” and said that it could eliminate the need for monthly visits for persons of non–childbearing potential. “This could substantially reduce logistical burdens for patients and reduce wait times to see a dermatologist,” he said.

Future changes to iPLEDGE that Dr. Barbieri would like to see include allowing for home pregnancy tests prior to starting therapy — particularly the test after the 30-day window period. “In addition, it would be good to be able to reduce the 30-day waiting period prior to therapy to something shorter,” such as 14 days, which would still “reliably exclude pregnancy, particularly for those on stable long-acting reversible contraception,” he said. There are also opportunities to improve the iPLEDGE website functionality and to ensure that the website is accessible to patients with limited English proficiency, he added.

He also recommended greater transparency by the Isotretinoin Products Manufacturers Group and inclusion of input from diverse stakeholders such as dermatologists, patients, and pharmacists.

Primary care clinicians play a central role in maintaining the cardiovascular-kidney-metabolic (CKM) health of patients, according to a new advisory from the American Heart Association.

The advisory, published recently in Circulation introduces the concept of CKM health and reevaluates the relationships between obesity, diabetes, kidney disease, and cardiovascular disease (CVD).

“This approach not only raises awareness, it also empowers PCPs to diagnose and treat these conditions more holistically,” Salim Hayek, MD, associate professor of cardiovascular disease and internal medicine, and medical director of the Frankel Cardiovascular Center Clinics at the University of Michigan in Ann Arbor, said in an interview.

 

New CKM Staging, Testing, and Care Strategies

The advisory introduces a new scoring system that ranges from stage 0 (patients with no risk factors for CKM) through stage 4 (patients with clinical CVD in CKM syndrome). Each stage requires specific management strategies and may include screening starting at age 30 years for diabetes, hypertension, and heart failure.

“Stage 0 CKM is usually found in young people, and CKM risk factors and scores typically increase as people age,” said Sean M. Drake, MD, a primary care physician at Henry Ford Health in Sterling Heights, Michigan. 

Dr. Drake advised PCPs to encourage patients who are at stage 0 to maintain ideal cardiovascular health and to monitor those at risk of progressing through the stages.

While PCPs already perform many of the tests the advisory recommends, the conditions overlap and an abnormality in one system should prompt more testing for other conditions. Additional tests, such as urine albumin-creatinine ratio, and more frequent glomerular filtration rate and lipid profile are advised, according to Dr. Drake.

“There also appears to be a role for additional cardiac testing, including echocardiograms and coronary CT scans, and for liver fibrosis screening,” Dr. Drake said. “Medications such as SGLT2 inhibitors, GLP-1 receptor agonists, and ACE inhibitors, beyond current routine use, are emphasized.” 

To better characterize body composition and help diagnose metabolic syndrome, the advisory also recommends measuring waist circumference, which is not routine practice, noted Joshua J. Joseph, MD, MPH, an associate professor of endocrinology, diabetes, and metabolism at The Ohio State University Wexner Medical Center in Columbus, and a co-author of the advisory. 

Recognizing the interconnected nature of cardiac, kidney, and metabolic diseases encourages a shift in mindset for clinicians, according to Neha Pagidipati, MD, MPH, a cardiologist at Duke Health in Durham, North Carolina.

“We have often been trained to focus on the specific problem in front of us,” Dr. Pagidipati said. “We need to be hyper-aware that many patients we see are at risk for multiple CKM entities. We need to be proactive about screening for and treating these when appropriate.”

The advisory emphasizes the need for CKM coordinators to support teams of clinicians from primary care, cardiology, endocrinology, nephrology, nursing, and pharmacy, as well as social workers, care navigators, or community health workers, Dr. Joseph said. 

“The advisory repositions the PCP at the forefront of CKM care coordination, marking a departure from the traditional model where subspecialists primarily manage complications,” Dr. Hayek added.
 

Changes to Payment

The new recommendations are consistent with current management guidelines for obesity, hypertriglyceridemia, hypertension, type 2 diabetes, and chronic kidney disease. 

“The advisory provides integrated algorithms for cardiovascular prevention and management, with specific therapeutic guidance tied to CKM stages, bringing together the current evidence for best practices from the various guidelines and filling gaps in a unified approach,” Dr. Joseph said. 

In addition, the advisory draws attention to the care of younger patients, who may be at increased risk for cardiovascular disease due to lifestyle factors, according to Nishant Shah, MD, assistant professor of medicine at Duke. 

“It considers barriers to care that prevent people from optimizing their cardiovascular health,” Dr. Shah said. 

Although the advisory does not specify proposed payment changes to support the new care model, the move towards value-based care may require billing practices that accommodate integrated care as well as more frequent and more specialized testing, Dr. Hayek said. 

“The advisory is an empowering tool for PCPs, underscoring their critical role in healthcare,” Dr. Hayek said. “It encourages PCPs to advocate for integrated care within their practices and to consider workflow adjustments that enhance the identification and initiation of preventive care for at-risk patients.”

Funding information was not provided.

Dr. Pagidipati reports relevant financial involvement with pharmaceutical companies. Dr. Hayek, Dr. Drake, and Dr. Shah report no relevant financial involvements. Dr. Joseph is an author of the advisory. Dr. Pagidipati, Dr. Hayek, Dr. Drake, and Dr. Shah were not involved in the writing of the advisory.

In addition, the advisory draws attention to the care of younger patients, who may be at increased risk for cardiovascular disease due to lifestyle factors, according to Nishant Shah, MD, assistant professor of medicine at Duke. 

“It considers barriers to care that prevent people from optimizing their cardiovascular health,” Dr. Shah said. 

Although the advisory does not specify proposed payment changes to support the new care model, the move towards value-based care may require billing practices that accommodate integrated care as well as more frequent and more specialized testing, Dr. Hayek said. 

“The advisory is an empowering tool for PCPs, underscoring their critical role in healthcare,” Dr. Hayek said. “It encourages PCPs to advocate for integrated care within their practices and to consider workflow adjustments that enhance the identification and initiation of preventive care for at-risk patients.”

Primary care clinicians play a central role in maintaining the cardiovascular-kidney-metabolic (CKM) health of patients, according to a new advisory from the American Heart Association.

The advisory, published recently in Circulation introduces the concept of CKM health and reevaluates the relationships between obesity, diabetes, kidney disease, and cardiovascular disease (CVD).

“This approach not only raises awareness, it also empowers PCPs to diagnose and treat these conditions more holistically,” Salim Hayek, MD, associate professor of cardiovascular disease and internal medicine, and medical director of the Frankel Cardiovascular Center Clinics at the University of Michigan in Ann Arbor, said in an interview.

 

New CKM Staging, Testing, and Care Strategies

The advisory introduces a new scoring system that ranges from stage 0 (patients with no risk factors for CKM) through stage 4 (patients with clinical CVD in CKM syndrome). Each stage requires specific management strategies and may include screening starting at age 30 years for diabetes, hypertension, and heart failure.

“Stage 0 CKM is usually found in young people, and CKM risk factors and scores typically increase as people age,” said Sean M. Drake, MD, a primary care physician at Henry Ford Health in Sterling Heights, Michigan. 

Dr. Drake advised PCPs to encourage patients who are at stage 0 to maintain ideal cardiovascular health and to monitor those at risk of progressing through the stages.

While PCPs already perform many of the tests the advisory recommends, the conditions overlap and an abnormality in one system should prompt more testing for other conditions. Additional tests, such as urine albumin-creatinine ratio, and more frequent glomerular filtration rate and lipid profile are advised, according to Dr. Drake.

“There also appears to be a role for additional cardiac testing, including echocardiograms and coronary CT scans, and for liver fibrosis screening,” Dr. Drake said. “Medications such as SGLT2 inhibitors, GLP-1 receptor agonists, and ACE inhibitors, beyond current routine use, are emphasized.” 

To better characterize body composition and help diagnose metabolic syndrome, the advisory also recommends measuring waist circumference, which is not routine practice, noted Joshua J. Joseph, MD, MPH, an associate professor of endocrinology, diabetes, and metabolism at The Ohio State University Wexner Medical Center in Columbus, and a co-author of the advisory. 

Recognizing the interconnected nature of cardiac, kidney, and metabolic diseases encourages a shift in mindset for clinicians, according to Neha Pagidipati, MD, MPH, a cardiologist at Duke Health in Durham, North Carolina.

“We have often been trained to focus on the specific problem in front of us,” Dr. Pagidipati said. “We need to be hyper-aware that many patients we see are at risk for multiple CKM entities. We need to be proactive about screening for and treating these when appropriate.”

The advisory emphasizes the need for CKM coordinators to support teams of clinicians from primary care, cardiology, endocrinology, nephrology, nursing, and pharmacy, as well as social workers, care navigators, or community health workers, Dr. Joseph said. 

“The advisory repositions the PCP at the forefront of CKM care coordination, marking a departure from the traditional model where subspecialists primarily manage complications,” Dr. Hayek added.
 

Changes to Payment

The new recommendations are consistent with current management guidelines for obesity, hypertriglyceridemia, hypertension, type 2 diabetes, and chronic kidney disease. 

“The advisory provides integrated algorithms for cardiovascular prevention and management, with specific therapeutic guidance tied to CKM stages, bringing together the current evidence for best practices from the various guidelines and filling gaps in a unified approach,” Dr. Joseph said. 

In addition, the advisory draws attention to the care of younger patients, who may be at increased risk for cardiovascular disease due to lifestyle factors, according to Nishant Shah, MD, assistant professor of medicine at Duke. 

“It considers barriers to care that prevent people from optimizing their cardiovascular health,” Dr. Shah said.

TOPLINE: 

Having a first menstrual period (menarche) at age 10 or younger was linked with a greater risk for type 2 diabetes and a greater risk of stroke in women with diabetes, a retrospective study of US women under age 65 found.

METHODOLOGY:

• Researchers analyzed data from 17,377 women who were aged 20-65 years when they participated in a National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018 and reported their age at first menstruation, which was classified as ≤ 10, 11, 12, 13, 14, or ≥ 15 years of age.
• In total, 0.2% of the women (1773) had type 2 diabetes; of these, 11.5% (205) had cardiovascular disease (CVD), defined as coronary heart disease (CHD), myocardial infarction, or stroke.
• Compared with women who had their first menstrual period at age 13 (the mean age in this population), those who had their period at age ≤ 10 had a significantly greater risk of having type 2 diabetes, after adjustment for age, race/ethnicity, education, parity, menopause status, family history of diabetes, smoking status, physical activity, alcohol consumption, and body mass index (odds ratio, 1.32; 95% CI, 1.03-1.69; P trend = .03).
• Among the women with diabetes, compared with those who had their first menstrual period at age 13, those who had it at age ≤ 10 had a significantly greater risk of having stroke (OR, 2.66; 95% CI, 1.07-6.64; P trend = .02), but not CVD or CHD, after adjustment for these multiple variables.

TAKEAWAY:

• In a racially and ethnically diverse national sample of US women younger than 65, “extremely early” age at first menstrual period was associated with significantly increased risk for type 2 diabetes; among the women with type 2 diabetes, it was associated with significantly increased risk for stroke but not CVD or CHD, after adjustment for multiple variables.
• Early age at menarche may be an early indicator of the cardiometabolic disease trajectory in women.

IN PRACTICE:

“Women with early-life exposures such as early age at menarche need to be further examined for diabetes and prevention research and strategies for progression of diabetes complications,” the study authors write. 

SOURCE:

The authors, mainly from Tulane University School of Public Health and Tropical Medicine, New Orleans, Louisiana, and also from Harvard Medical School, Boston, Massachusetts, published their findings in BMJ Nutrition, Prevention & Health.

LIMITATIONS:

• The women who participated in NHANES may not be representative of all women in the United States (selection bias).
• The study only included women who reported the age when they had their first menstrual period (selection bias).
• This was a cross-sectional, observational study, so it cannot show causality.
• The women may have reported the wrong age at which they had their first period (recall bias and social desirability bias).
• The women may have inaccurately reported CVD and type 2 diabetes (recall bias and social desirability bias).

DISCLOSURES:

The researchers were supported by grants from the National Heart, Lung, and Blood Institute and from the National Institute of General Medical Sciences of the National Institutes of Health.

Scientists know that tinnitus, or ringing in the ears, affects 10% of adults worldwide. But they’re not exactly sure what causes the condition.

The traditional belief is that tinnitus happens in people who had already lost hearing. But some people who have tinnitus are still able to perform well on standard hearing tests, according to researchers at the Massachusetts Eye and Ear Infirmary. That happens because the tests don’t pick up auditory nerve loss, sometimes called “hidden hearing loss.” 

“Our work reconciles the idea that tinnitus may be triggered by a loss of auditory nerve, including in people with normal hearing,” Stéphane F. Maison, PhD, the lead author of a new study on tinnitus, said in a news release about the study.

Tinnitus is sometimes compared to phantom limb syndrome, in which people feel pain in limbs they no longer have. While the study published in Scientific Reports doesn’t refer to phantom limb syndrome, it does talk about “phantom sound.”

“In other words, the brain tries to compensate for the loss of hearing by increasing its activity, resulting in the perception of a phantom sound, tinnitus. Until recently though, this idea was disputed as some tinnitus sufferers have normal hearing tests,” the researchers explained in the news release. 

Annoyed by the ringing in your ears? What causes tinnitus, and how can you get the sound to buzz off?

The study included 294 adults — 201 who had never reported having tinnitus, 64 who had reported having temporary tinnitus, and 29 who had reported having constant tinnitus for 6 months or more. 

All 294 had performed normally on a pure tone test, in which subjects raise their hands when they hear beeps to measure the quietest sounds they can detect.

In a different kind of test, electrodes measured responses to clicking sounds in the inner ear, the auditory nerve, and the brain. The second test found reduced response in the auditory nerves and increased activity in the brainstem activity among those who had tinnitus.

Dr Maison, a principal investigator at Eaton-Peabody Laboratories at Mass Eye and Ear/Harvard Medical School, called the study “a first step toward our ultimate goal of silencing tinnitus.”

“Beyond the nuisance of having persistent ringing or other sounds in the ears, tinnitus symptoms are debilitating in many patients, causing sleep deprivation, social isolation, anxiety and depression, adversely affecting work performance, and reducing significantly their quality of life,” he said in the news release. “We won’t be able to cure tinnitus until we fully understand the mechanisms underlying its genesis.”

TOPLINE:

Changes in statin prescribing guidelines in 2013 had little effect on statin use for patients who are at risk for atherosclerotic cardiovascular disease (ASCVD), according to a study published Dec. 5 in the Annals of Internal Medicine. 

METHODOLOGY:

• Statins lower cholesterol and can reduce the risk for heart and circulatory disease.
• In 2013, the American College of Cardiology and the American Heart Association (ACC/AHA) expanded indications for which clinicians could prescribe statins to adults for primary prevention, including risk scores for ASCVD above a certain threshold. 
• Researchers studied trends in statin use between 1999 and 2018 using National Health and Nutrition Examination Survey data for 21,961 adults older than 20 years who did not have ASCVD. 
• They analyzed data from before and after implementation of the 2013 guidelines.

TAKEAWAY:

• Statin usage increased since 1999 but peaked at 35% in 2013 despite the expanded ACC/AHA guidelines.
• No changes in usage were observed for the proportion of adults who were newly eligible for statins. 
• Statin use among patients with diabetes increased by 31.1 percentage points between 1999 and 2014 but then remained stagnant from 2014 to 2018.
• Statin use among those with ASCVD risk of more than 20% increased by 23.1 percentage points between 1999 and 2013 but did not increase between 2013 and 2018.

IN PRACTICE:

“Although the ACC/AHA guidelines expanded indications for primary prevention, they also increased decision-making complexity, requiring new multistep risk calculation… Many clinicians do not routinely use cardiovascular risk calculators because of a lack of time, input availability, or buy-in. Electronic health record tools that calculate ASCVD risks show promise, but they are not routinely implemented and do not address other barriers, such as competing patient priorities and limited time for shared decision-making.“

SOURCE:

The study was led by Timothy S. Anderson, MD, MAS, Division of General Internal Medicine, at the University of Pittsburgh. The research was funded by the National Institute on Aging of the National Institutes of Health.

LIMITATIONS:

Data on whether patients had previously been offered and declined statins were not available. Risk score data for baseline ASCVD, which affects risk classification, were also not available.

DISCLOSURES:

The authors report no disclosures.
