How to improve diagnosis of HFpEF, common in diabetes

Article Type

Thu, 12/15/2022 - 14:24

– Recent study results confirm that two agents from the sodium-glucose cotransporter 2 (SGLT2) inhibitor class can significantly cut the incidence of adverse cardiovascular events in patients with heart failure with reduced ejection fraction (HFpEF), a disease especially common in people with type 2 diabetes, obesity, or both.

And findings from secondary analyses of the studies – including one reported at the annual meeting of the European Association for the Study of Diabetes – show that these SGLT2 inhibitors work as well for cutting incident adverse events (cardiovascular death or worsening heart failure) in patients with HFpEF and diabetes as they do for people with normal blood glucose levels.

But delivering treatment with these proven agents, dapagliflozin (Farxiga) and empagliflozin (Jardiance), first requires diagnosis of HFpEF, a task that clinicians have historically fallen short in accomplishing.

When in 2021, results from the EMPEROR-Preserved trial with empagliflozin and when in September 2022 results from the DELIVER trial with dapagliflozin established the efficacy of these two SGLT2 inhibitors as the first treatments proven to benefit patients with HFpEF, they also raised the stakes for clinicians to be much more diligent and systematic in evaluating people at high risk for developing HFpEF because of having type 2 diabetes or obesity, two of the most potent risk factors for this form of heart failure.
 

‘Vigilance ... needs to increase’

“Vigilance for HFpEF needs to increase because we can now help these patients,” declared Lars H. Lund, MD, PhD, speaking at the meeting. “Type 2 diabetes dramatically increases the incidence of HFpEF,” and the mechanisms by which it does this are “especially amenable to treatment with SGLT2 inhibitors,” said Dr. Lund, a cardiologist and heart failure specialist at the Karolinska Institute, Stockholm.

HFpEF has a history of going undetected in people with type 2 diabetes, an ironic situation given its high incidence as well as the elevated rate of adverse cardiovascular events when heart failure occurs in patients with type 2 diabetes compared with patients who do not have diabetes.

The key, say experts, is for clinicians to maintain a high index of suspicion for signs and symptoms of heart failure in people with type 2 diabetes and to regularly assess them, starting with just a few simple questions that probe for the presence of dyspnea, exertional fatigue, or both, an approach not widely employed up to now.

Clinicians who care for people with type 2 diabetes must become “alert to thinking about heart failure and alert to asking questions about signs and symptoms” that flag the presence of HFpEF, advised Naveed Sattar, MBChB, PhD, a professor of metabolic medicine at the University of Glasgow.

Soon, medical groups will issue guidelines for appropriate assessment for the presence of HFpEF in people with type 2 diabetes, Dr. Sattar predicted in an interview.
 

A need to probe

“You can’t simply ask patients with type 2 diabetes whether they have shortness of breath or exertional fatigue and stop there,” because often their first response will be no.

“Commonly, patients will initially say they have no dyspnea, but when you probe further, you find symptoms,” noted Mikhail N. Kosiborod, MD, codirector of Saint Luke’s Cardiometabolic Center of Excellence in Kansas City, Mo.

These people are often sedentary, so they frequently don’t experience shortness of breath at baseline, Dr. Kosiborod said in an interview. In some cases, they may limit their activity because of their exertional intolerance.

Once a person’s suggestive symptoms become known, the next step is to measure the serum level of N-terminal pro-B-type natriuretic peptide (NT-proBNP), a biomarker considered to be a generally reliable signal of existing heart failure when elevated.

Any value above 125 pg/mL is suggestive of prevalent heart failure and should lead to the next diagnostic step of echocardiography, Dr. Sattar said.

Elevated NT-proBNP has such good positive predictive value for identifying heart failure that it is tempting to use it broadly in people with type 2 diabetes. A 2022 consensus report from the American Diabetes Association says that “measurement of a natriuretic peptide [such as NT-proBNP] or high-sensitivity cardiac troponin is recommended on at least a yearly basis to identify the earliest HF [heart failure] stages and implement strategies to prevent transition to symptomatic HF.”
 

Test costs require targeting

But because of the relatively high current price for an NT-proBNP test, the cost-benefit ratio for widespread annual testing of all people with type 2 diabetes would be poor, some experts caution.

“Screening everyone may not be the right answer. Hundreds of millions of people worldwide” have type 2 diabetes. “You first need to target evaluation to people with symptoms,” advised Dr. Kosiborod.

He also warned that a low NT-proBNP level does not always rule out HFpEF, especially among people with type 2 diabetes who also have overweight or obesity, because NT-proBNP levels can be “artificially low” in people with obesity.

Other potential aids to diagnosis are assessment scores that researchers have developed, such as the H2FPEF score, which relies on variables that include age, obesity, and the presence of atrial fibrillation and hypertension.

However, this score also requires an echocardiography examination, another test that would have a questionable cost-benefit ratio if performed widely for patients with type 2 diabetes without targeting, Dr. Kosiborod said.
 

SGLT2 inhibitors benefit HFpEF regardless of glucose levels

A prespecified analysis of the DELIVER results that divided the study cohort on the basis of their glycemic status proved the efficacy of the SGLT2 inhibitor dapagliflozin for patients with HFpEF regardless of whether or not they had type 2 diabetes, prediabetes, or were normoglycemic at entry into the study, Silvio E. Inzucchi, MD, reported at the EASD meeting.

Treatment with dapagliflozin cut the incidence of the trial’s primary outcome of cardiovascular death or worsening heart failure by a significant 18% relative to placebo among all enrolled patients.

The new analysis reported by Dr. Inzucchi showed that treatment was associated with a 23% relative risk reduction among those with normoglycemia, a 13% reduction among those with prediabetes, and a 19% reduction among those with type 2 diabetes, with no signal of a significant difference among the three subgroups.

“There was no statistical interaction between categorical glycemic subgrouping and dapagliflozin’s treatment effect,” concluded Dr. Inzucchi, director of the Yale Medicine Diabetes Center, New Haven, Conn.

He also reported that, among the 6,259 people in the trial with HFpEF, 50% had diabetes, 31% had prediabetes, and a scant 19% had normoglycemia. The finding highlights once again the high prevalence of dysglycemia among people with HFpEF.

Previously, a prespecified secondary analysis of data from the EMPEROR-Preserved trial yielded similar findings for empagliflozin that showed the agent’s efficacy for people with HFpEF across the range of glucose levels.

The DELIVER trial was funded by AstraZeneca, the company that markets dapagliflozin (Farxiga). The EMPEROR-Preserved trial was sponsored by Boehringer Ingelheim and Eli Lilly, the companies that jointly market empagliflozin (Jardiance). Dr. Lund has been a consultant to AstraZeneca and Boehringer Ingelheim and to numerous other companies, and he is a stockholder in AnaCardio. Dr. Sattar has been a consultant to and has received research support from AstraZeneca and Boehringer Ingelheim, and he has been a consultant with numerous companies. Dr. Kosiborod has been a consultant to and has received research funding from AstraZeneca and Boehringer Ingelheim and has been a consultant to Eli Lilly and numerous other companies. Dr. Inzucchi has been a consultant to, given talks on behalf of, or served on trial committees for Abbott, AstraZeneca, Boehringer Ingelheim, Esperion, Lexicon, Merck, Novo Nordisk, Pfizer, and vTv Therapetics.

Once-weekly insulin promising in phase 3 trial in type 2 diabetes

Article Type

Thu, 12/15/2022 - 14:24

STOCKHOLM – The investigational once-weekly insulin icodec (Novo Nordisk) significantly reduces A1c without increasing hypoglycemia in people with type 2 diabetes, the first phase 3 data of such an insulin formulation suggest. The data are from one of six trials in the company’s ONWARDS program.

“Once-weekly insulin may redefine diabetes management,” enthused Athena Philis-Tsimikas, MD, who presented the findings at a session during the European Association for the Study of Diabetes (EASD) 2022 Annual Meeting, which also included a summary of previously reported top-line data from other ONWARDS trials as well as phase 2 data for Lilly›s investigational once-weekly Basal Insulin Fc (BIF).

Phase 2 data for icodec were published in 2020 in the New England Journal of Medicine and in 2021 in Diabetes Care, as reported by this news organization.

The capacity for reducing the number of basal insulin injections from at least 365 to just 52 per year means that once-weekly insulin “has the potential to facilitate insulin initiation and improve treatment adherence and persistence in diabetes,” noted Dr. Philis-Tsimikas, corporate vice president of Scripps Whittier Diabetes Institute, San Diego.

Asked to comment, independent diabetes industry consultant Charles Alexander, MD, told this news organization that the new data from ONWARDS 2 of patients switching from daily to once-weekly basal insulin were reassuring with regard to hypoglycemia, at least for people with type 2 diabetes.

“For type 2, I think there’s enough data now to feel comfortable that it’s going to be good, especially for people who are on once-weekly [glucagon-like peptide-1 (GLP-1) agonists].”

However, for type 1 diabetes, the company reported top-line ONWARDS 6 data earlier this year, in which icodec was associated with significantly increased rates of hypoglycemia compared with daily degludec. “In type 1, even the basal needs are [often] changing. That kind of person would want to stay away from once-weekly insulin,” Dr. Alexander said.

And he noted, for any patient who adjusts their insulin dose frequently, “obviously, you’re not going to be able to do that with a once-weekly.”
 

Similar A1c reduction as daily basal without increased hypoglycemia

In ONWARDS 2, 526 adults with type 2 diabetes were randomized to switch from their current once- or twice-daily basal insulin to either once-weekly icodec or once-daily insulin degludec (Tresiba) for 26 weeks. The study was open-label, with a treat-to-glucose target of 80-130 mg/dL design.

Participants had A1c levels of 7.0%-10.0% and were also taking stable doses of other noninsulin glucose-lowering medications. Over 80% were taking metformin, a third were taking an SGLT2 inhibitor, and about a quarter each were taking a GLP-1 agonist or DPP-4 inhibitor. Those medications were continued, but sulfonylureas were discontinued in the 22% taking those at baseline.

The basal insulin used at baseline was glargine U100 for 42%, degludec for 28%, and glargine U300 for 16%, “so, a very typical presentation of patients we see in our practices today,” Dr. Philis-Tsimikas noted.

The primary endpoint, change in A1c from baseline to week 26, dropped from 8.17% to 7.20% with icodec and from 8.10% to 7.42% with degludec. The estimated treatment difference of –0.22 percentage points met the margins for both noninferiority (P < .0001) and superiority (P = .0028). Those taking icodec were significantly more likely to achieve an A1c under 7% compared with degludec, at 40.3% versus 26.5% (P = .0019).

Continuous glucose monitoring parameters during weeks 22-26 showed time in glucose range of 70-180 mg/dL (3.9-10.0 mmol/L) was 63.1% for icodec and 59.5% for degludec, which was not significantly different, Dr. Philis-Tsimikas reported.

Body weight increased by 1.4 kg (3 lb) with icodec but dropped slightly by 0.30 kg with degludec, which was significantly different (P < .001).

When asked about the body weight results, Dr. Alexander said: “It’s really hard to say. We know that insulin generally causes weight gain. A 1.4-kg weight gain over 6 months isn’t really surprising. Why there wasn’t with degludec, I don’t know.”

There was just one episode of severe hypoglycemia (requiring assistance) in the trial in the degludec group. Rates of combined severe or clinically significant hypoglycemic events (glucose < 54 mg/dL / < 3.0 mmol/L) per patient-year exposed were 0.73 for icodec versus 0.27 for degludec, which was not significantly different (P = .0782). Similar findings were seen for nocturnal hypoglycemia.

Significantly more patients achieved an A1c under 7% without significant hypoglycemia with icodec than degludec, at 36.7% versus 26.8% (P = .0223). Other adverse events were equivalent between the two groups, Dr. Philis-Tsimikas reported.

Scores on the diabetes treatment satisfaction questionnaire, which addresses convenience, flexibility, satisfaction, and willingness to recommend treatment to others, were significantly higher for icodec than degludec, at 4.22 versus 2.96 (P = .0036).

“For me, this is one of the most important outcomes,” she commented.  
 

 

 

Benefit in type 2 diabetes, potential concern in type 1 diabetes

Top-line results from ONWARDS 1, a phase 3a 78-week trial in 984 drug-naive people with type 2 diabetes and ONWARDS 6, a 52-week trial in 583 people with type 1 diabetes, were presented earlier this year at the American Diabetes Association 81st Scientific Sessions.

In ONWARDS 1, icodec achieved noninferiority to daily insulin glargine, reducing A1c by 1.55 versus 1.35 percentage points, with superior time in range and no significant differences in hypoglycemia rates.

However, in ONWARDS 6, while noninferiority in A1c lowering compared with daily degludec was achieved, with reductions of 0.47 versus 0.51 percentage points from a baseline A1c of 7.6%, there was a significantly greater rate of severe or clinically significant hypoglycemia with icodec, at 19.93 versus 10.37 events per patient-year with degludec.

Dr. Philis-Tsimikas has reported performing research and serving as an advisor on behalf of her employer for Abbott, Bayer, Dexcom, Eli Lilly, Medtronic, Merck, Novo Nordisk, and Sanofi. All reimbursements go to her employer. Dr. Alexander has reported being a nonpaid advisor for diaTribe and a consultant for Kinexum.

“Once-weekly insulin may redefine diabetes management,” enthused Athena Philis-Tsimikas, MD, who presented the findings at a session during the European Association for the Study of Diabetes (EASD) 2022 Annual Meeting, which also included a summary of previously reported top-line data from other ONWARDS trials as well as phase 2 data for Lilly›s investigational once-weekly Basal Insulin Fc (BIF).

Phase 2 data for icodec were published in 2020 in the New England Journal of Medicine and in 2021 in Diabetes Care, as reported by this news organization.

The capacity for reducing the number of basal insulin injections from at least 365 to just 52 per year means that once-weekly insulin “has the potential to facilitate insulin initiation and improve treatment adherence and persistence in diabetes,” noted Dr. Philis-Tsimikas, corporate vice president of Scripps Whittier Diabetes Institute, San Diego.

Asked to comment, independent diabetes industry consultant Charles Alexander, MD, told this news organization that the new data from ONWARDS 2 of patients switching from daily to once-weekly basal insulin were reassuring with regard to hypoglycemia, at least for people with type 2 diabetes.

“For type 2, I think there’s enough data now to feel comfortable that it’s going to be good, especially for people who are on once-weekly [glucagon-like peptide-1 (GLP-1) agonists].”

However, for type 1 diabetes, the company reported top-line ONWARDS 6 data earlier this year, in which icodec was associated with significantly increased rates of hypoglycemia compared with daily degludec. “In type 1, even the basal needs are [often] changing. That kind of person would want to stay away from once-weekly insulin,” Dr. Alexander said.

And he noted, for any patient who adjusts their insulin dose frequently, “obviously, you’re not going to be able to do that with a once-weekly.”
 

Similar A1c reduction as daily basal without increased hypoglycemia

In ONWARDS 2, 526 adults with type 2 diabetes were randomized to switch from their current once- or twice-daily basal insulin to either once-weekly icodec or once-daily insulin degludec (Tresiba) for 26 weeks. The study was open-label, with a treat-to-glucose target of 80-130 mg/dL design.

Participants had A1c levels of 7.0%-10.0% and were also taking stable doses of other noninsulin glucose-lowering medications. Over 80% were taking metformin, a third were taking an SGLT2 inhibitor, and about a quarter each were taking a GLP-1 agonist or DPP-4 inhibitor. Those medications were continued, but sulfonylureas were discontinued in the 22% taking those at baseline.

The basal insulin used at baseline was glargine U100 for 42%, degludec for 28%, and glargine U300 for 16%, “so, a very typical presentation of patients we see in our practices today,” Dr. Philis-Tsimikas noted.

The primary endpoint, change in A1c from baseline to week 26, dropped from 8.17% to 7.20% with icodec and from 8.10% to 7.42% with degludec. The estimated treatment difference of –0.22 percentage points met the margins for both noninferiority (P < .0001) and superiority (P = .0028). Those taking icodec were significantly more likely to achieve an A1c under 7% compared with degludec, at 40.3% versus 26.5% (P = .0019).

Continuous glucose monitoring parameters during weeks 22-26 showed time in glucose range of 70-180 mg/dL (3.9-10.0 mmol/L) was 63.1% for icodec and 59.5% for degludec, which was not significantly different, Dr. Philis-Tsimikas reported.

Body weight increased by 1.4 kg (3 lb) with icodec but dropped slightly by 0.30 kg with degludec, which was significantly different (P < .001).

When asked about the body weight results, Dr. Alexander said: “It’s really hard to say. We know that insulin generally causes weight gain. A 1.4-kg weight gain over 6 months isn’t really surprising. Why there wasn’t with degludec, I don’t know.”

There was just one episode of severe hypoglycemia (requiring assistance) in the trial in the degludec group. Rates of combined severe or clinically significant hypoglycemic events (glucose < 54 mg/dL / < 3.0 mmol/L) per patient-year exposed were 0.73 for icodec versus 0.27 for degludec, which was not significantly different (P = .0782). Similar findings were seen for nocturnal hypoglycemia.

Significantly more patients achieved an A1c under 7% without significant hypoglycemia with icodec than degludec, at 36.7% versus 26.8% (P = .0223). Other adverse events were equivalent between the two groups, Dr. Philis-Tsimikas reported.

Scores on the diabetes treatment satisfaction questionnaire, which addresses convenience, flexibility, satisfaction, and willingness to recommend treatment to others, were significantly higher for icodec than degludec, at 4.22 versus 2.96 (P = .0036).

“For me, this is one of the most important outcomes,” she commented.  
 

 

 

Benefit in type 2 diabetes, potential concern in type 1 diabetes

Top-line results from ONWARDS 1, a phase 3a 78-week trial in 984 drug-naive people with type 2 diabetes and ONWARDS 6, a 52-week trial in 583 people with type 1 diabetes, were presented earlier this year at the American Diabetes Association 81st Scientific Sessions.

In ONWARDS 1, icodec achieved noninferiority to daily insulin glargine, reducing A1c by 1.55 versus 1.35 percentage points, with superior time in range and no significant differences in hypoglycemia rates.

However, in ONWARDS 6, while noninferiority in A1c lowering compared with daily degludec was achieved, with reductions of 0.47 versus 0.51 percentage points from a baseline A1c of 7.6%, there was a significantly greater rate of severe or clinically significant hypoglycemia with icodec, at 19.93 versus 10.37 events per patient-year with degludec.

Dr. Philis-Tsimikas has reported performing research and serving as an advisor on behalf of her employer for Abbott, Bayer, Dexcom, Eli Lilly, Medtronic, Merck, Novo Nordisk, and Sanofi. All reimbursements go to her employer. Dr. Alexander has reported being a nonpaid advisor for diaTribe and a consultant for Kinexum.

Hormones’ impact described in transgender rheumatology patients

Article Type

Fri, 09/30/2022 - 13:08

Gender-affirming hormone therapy’s effect on transgender patients with rheumatic disease is unclear but does not appear to modulate its course and does not need to be strictly contraindicated in most patients, according to a case series and systematic literature review.

More doctors are practicing transgender medicine, yet a limited amount of information is available on rheumatic disease in transgender and gender diverse (TGGD) individuals, Kristen Mathias, MD, a rheumatology fellow at Johns Hopkins University, Baltimore, said in her presentation of the study at the Lancet Summit on Sex and Gender in Rheumatology.

Dr. Kristen Mathias

“This is important, as it is well known that sex hormones affect the pathogenesis and expression of autoimmune diseases,” Dr. Mathias said. Knowing more about the effects of gender-affirming hormone therapy (GAHT) and gender-affirming surgery on disease activity in TGGD individuals could better inform decisions about care in this population.

Dr. Mathias and colleagues identified 7 transgender patients with rheumatic diseases from a pool of 1,053 patients seen at the Los Angeles County and University of Southern California Medical Center, Los Angeles, from June 2019 to June 2021. This included five transgender males and two transgender females. They ranged in age from 13 to 52 years.

All seven were on GAHT, and its impact on disease activity was considered “possible” in two of the seven patients.

In a systematic literature review, investigators found 11 studies that included 11 transgender women and 2 transgender men, ranging in age from 22 to 49 years. All the patients were on GAHT. In 12 of 13 patients, the hormones were considered possibly related to their rheumatic disease activity.

The 20 patients had diagnoses of rheumatoid arthritis, cutaneous and systemic lupus erythematosus, adult-onset Still disease, spondyloarthritis, myositis, and systemic sclerosis.

GAHT should not be a strict contraindication in these patients, based on these findings, Dr. Mathias noted. Information to clarify the effect of GAHT on rheumatic disease is sparse, however. Physicians should adopt a personalized, shared decision-making approach when consulting patients.

“During patient encounters, they should be screened for psychosocial barriers when appropriate,” Dr. Mathias recommended.

Findings could pave way for larger studies, more data

Studies on the impact and consequences of rheumatic disease in TGGD individuals are sorely lacking, said Vagishwari Murugesan, MBBS, a clinical fellow in rheumatology at the University of Toronto.

“While this is a small study of only seven patients and no conclusive results can be drawn, studies like these can help pave the way for larger multicentric studies, which can give us more definitive data on gender-affirming hormone therapy and its consequences on rheumatic diseases,” said Dr. Murugesan, who was not involved in the study.

A registry would be a great way to collaborate with other stakeholders interested in the same topic and conduct larger studies, she said. “I would recommend that not only do we screen for psychosocial barriers but also actively engage as a health care community in addressing how we can overcome the barriers for patients to access effective health care.”

No external funding was obtained for the study.

Ezetimibe-statin combo lowers liver fat in open-label trial

Article Type
Changed
Thu, 12/15/2022 - 14:24

Ezetimibe given in combination with rosuvastatin has a beneficial effect on liver fat in people with nonalcoholic fatty liver disease (NAFLD), according results of a randomized, active-controlled trial.

The findings, which come from the investigator-initiated ESSENTIAL trial, are likely to add to the debate over whether or not the lipid-lowering combination could be of benefit beyond its effects in the blood.

Dr_Microbe/Getty Images

“We used magnetic resonance imaging-derived proton density fat fraction [MRI-PDFF], which is highly reliable method of assessing hepatic steatosis,” Youngjoon Kim, PhD, one of the study investigators, said at the annual meeting of the European Association for the Study of Diabetes in Barcelona.

“It enables accurate, repeatable and reproducible quantitative assessment of liver fat over the entire liver,” observed Dr. Kim, who works at Severance Hospital, part of Yonsei University in Seoul.

He reported that there was a significant 5.8% decrease in liver fat following 24 weeks’ treatment with ezetimibe and rosuvastatin comparing baseline with end of treatment MRI-PDFF values; a drop that was significant (18.2% vs. 12.3%, P < .001).

Rosuvastatin monotherapy also reduced liver fat from 15.0% at baseline to 12.4% after 24 weeks; this drop of 2.6% was also significant (P = .003).

This gave an absolute mean difference between the two study arms of 3.2% (P = .02).
 

Rationale for the ESSENTIAL study

Dr. Kim observed during his presentation that NAFLD is burgeoning problem around the world. Ezetimibe plus rosuvastatin was a combination treatment already used widely in clinical practice, and there had been some suggestion that ezetimibe might have an effect on liver fat.

“Although the effect of ezetimibe on hepatic steatosis is still controversial, ezetimibe has been reported to reduce visceral fat and improve insulin resistance in several studies” Dr. Kim said.

“Recently, our group reported that the use of ezetimibe affects autophagy of hepatocytes and the NLRP3 [NOD-like receptors containing pyrin domain 3] inflammasome,” he said.

Moreover, he added, “ezetimibe improved NASH [nonalcoholic steatohepatitis] in an animal model. However, the effects of ezetimibe have not been clearly shown in a human study.”

Dr. Kim also acknowledged a prior randomized control trial that had looked at the role of ezetimibe in 50 patients with NASH, but had not shown a benefit for the drug over placebo in terms of liver fat reduction.
 

Addressing the Hawthorne effect

“The size of the effect by that might actually be more modest due to the Hawthorne effect,” said session chair Onno Holleboom, MD, PhD, of Amsterdam UMC in the Netherlands.

“What we observe in the large clinical trials is an enormous Hawthorne effect – participating in a NAFLD trial makes people live healthier because they have health checks,” he said.

“That’s a major problem for showing efficacy for the intervention arm,” he added, but of course the open design meant that the trial only had intervention arms; “there was no placebo arm.”
 

A randomized, active-controlled, clinician-initiated trial

The main objective of the ESSENTIAL trial was therefore to take another look at the potential effect of ezetimibe on hepatic steatosis and doing so in the setting of statin therapy.

In all, 70 patients with NAFLD that had been confirmed via ultrasound were recruited into the prospective, single center, phase 4 trial. Participants were randomized 1:1 to received either ezetimibe 10 mg plus rosuvastatin 5 mg daily or rosuvastatin 5 mg for up to 24 weeks.

Change in liver fat was measured via MRI-PDFF, taking the average values in each of nine liver segments. Magnetic resonance elastography (MRE) was also used to measure liver fibrosis, although results did not show any differences either from baseline to end of treatment values in either group or when the two treatment groups were compared.

Dr. Kim reported that both treatment with the ezetimibe-rosuvastatin combination and rosuvastatin monotherapy reduced parameters that might be associated with a negative outcome in NAFLD, such as body mass index and waist circumference, triglycerides, and LDL cholesterol. There was also a reduction in C-reactive protein levels in the blood, and interleulin-18. There was no change in liver enzymes.

Several subgroup analyses were performed indicating that “individuals with higher BMI, type 2 diabetes, insulin resistance, and severe liver fibrosis were likely to be good responders to ezetimibe treatment,” Dr. Kim said.

“These data indicate that ezetimibe plus rosuvastatin is a safe and effective therapeutic option to treat patients with NAFLD and dyslipidemia,” he concluded.

The results of the ESSENTIAL study have been published in BMC Medicine.

The study was funded by the Yuhan Corporation. Dr. Kim had no conflicts of interest to report. Dr. Holleboom was not involved in the study and had no conflicts of interest.

There was also a reduction in C-reactive protein levels in the blood, and interleulin-18. There was no change in liver enzymes.

Several subgroup analyses were performed indicating that “individuals with higher BMI, type 2 diabetes, insulin resistance, and severe liver fibrosis were likely to be good responders to ezetimibe treatment,” Dr. Kim said.

“These data indicate that ezetimibe plus rosuvastatin is a safe and effective therapeutic option to treat patients with NAFLD and dyslipidemia,” he concluded.

The results of the ESSENTIAL study have been published in BMC Medicine.

The study was funded by the Yuhan Corporation. Dr. Kim had no conflicts of interest to report. Dr. Holleboom was not involved in the study and had no conflicts of interest.

Ezetimibe given in combination with rosuvastatin has a beneficial effect on liver fat in people with nonalcoholic fatty liver disease (NAFLD), according results of a randomized, active-controlled trial.

The findings, which come from the investigator-initiated ESSENTIAL trial, are likely to add to the debate over whether or not the lipid-lowering combination could be of benefit beyond its effects in the blood.

“We used magnetic resonance imaging-derived proton density fat fraction [MRI-PDFF], which is highly reliable method of assessing hepatic steatosis,” Youngjoon Kim, PhD, one of the study investigators, said at the annual meeting of the European Association for the Study of Diabetes in Barcelona.

“It enables accurate, repeatable and reproducible quantitative assessment of liver fat over the entire liver,” observed Dr. Kim, who works at Severance Hospital, part of Yonsei University in Seoul.

He reported that there was a significant 5.8% decrease in liver fat following 24 weeks’ treatment with ezetimibe and rosuvastatin comparing baseline with end of treatment MRI-PDFF values; a drop that was significant (18.2% vs. 12.3%, P < .001).

Rosuvastatin monotherapy also reduced liver fat from 15.0% at baseline to 12.4% after 24 weeks; this drop of 2.6% was also significant (P = .003).

This gave an absolute mean difference between the two study arms of 3.2% (P = .02).
 

Rationale for the ESSENTIAL study

Dr. Kim observed during his presentation that NAFLD is burgeoning problem around the world. Ezetimibe plus rosuvastatin was a combination treatment already used widely in clinical practice, and there had been some suggestion that ezetimibe might have an effect on liver fat.

“Although the effect of ezetimibe on hepatic steatosis is still controversial, ezetimibe has been reported to reduce visceral fat and improve insulin resistance in several studies” Dr. Kim said.

“Recently, our group reported that the use of ezetimibe affects autophagy of hepatocytes and the NLRP3 [NOD-like receptors containing pyrin domain 3] inflammasome,” he said.

Moreover, he added, “ezetimibe improved NASH [nonalcoholic steatohepatitis] in an animal model. However, the effects of ezetimibe have not been clearly shown in a human study.”

Dr. Kim also acknowledged a prior randomized control trial that had looked at the role of ezetimibe in 50 patients with NASH, but had not shown a benefit for the drug over placebo in terms of liver fat reduction.
 

Addressing the Hawthorne effect

“The size of the effect by that might actually be more modest due to the Hawthorne effect,” said session chair Onno Holleboom, MD, PhD, of Amsterdam UMC in the Netherlands.

“What we observe in the large clinical trials is an enormous Hawthorne effect – participating in a NAFLD trial makes people live healthier because they have health checks,” he said.

“That’s a major problem for showing efficacy for the intervention arm,” he added, but of course the open design meant that the trial only had intervention arms; “there was no placebo arm.”
 

A randomized, active-controlled, clinician-initiated trial

The main objective of the ESSENTIAL trial was therefore to take another look at the potential effect of ezetimibe on hepatic steatosis and doing so in the setting of statin therapy.

In all, 70 patients with NAFLD that had been confirmed via ultrasound were recruited into the prospective, single center, phase 4 trial. Participants were randomized 1:1 to received either ezetimibe 10 mg plus rosuvastatin 5 mg daily or rosuvastatin 5 mg for up to 24 weeks.

Change in liver fat was measured via MRI-PDFF, taking the average values in each of nine liver segments. Magnetic resonance elastography (MRE) was also used to measure liver fibrosis, although results did not show any differences either from baseline to end of treatment values in either group or when the two treatment groups were compared.

Dr. Kim reported that both treatment with the ezetimibe-rosuvastatin combination and rosuvastatin monotherapy reduced parameters that might be associated with a negative outcome in NAFLD, such as body mass index and waist circumference, triglycerides, and LDL cholesterol. There was also a reduction in C-reactive protein levels in the blood, and interleulin-18. There was no change in liver enzymes.

Several subgroup analyses were performed indicating that “individuals with higher BMI, type 2 diabetes, insulin resistance, and severe liver fibrosis were likely to be good responders to ezetimibe treatment,” Dr. Kim said.

Does COVID-19 cause type 1 diabetes in children? Time will tell

– It remains inconclusive whether SARS-CoV-2 infection predisposes children and adolescents to a higher risk of type 1 diabetes. Data from two new studies and a recently published research letter add to the growing body of knowledge on the subject, but still can’t draw any definitive conclusions.

The latest results from a Norwegian and a Scottish study both examine incidence of type 1 diabetes in young people with a history of SARS-CoV-2 infection and were reported at the annual meeting of the European Association for the Study of Diabetes.

A 60% increased risk for type 1 diabetes at least 31 days after SARS-CoV-2 infection (adjusted hazard ratio, 1.63) was found in the Norwegian study, while in contrast, the Scottish study only found an increased risk in the first few months of the pandemic, in 2020, but importantly, no association over a much longer time period (March 2020–November 2021).

In a comment on Twitter on the two studies presented at EASD, session moderator Kamlesh Khunti, MD, professor of primary care diabetes and vascular medicine at the University of Leicester, (England), said: “In summary, two studies showing no or weak association of type 1 diabetes with COVID.”

But new data in the research letter published in JAMA Network Open, based on U.S. figures, also found an almost doubling of type 1 diabetes in children in the first few months after COVID-19 infection relative to infection with other respiratory viruses.

Lead author of the Scottish study, Helen Colhoun, PhD, honorary public health consultant at Public Health Scotland, commented: “Data in children are variable year on year, which emphasizes the need to be cautious over taking a tiny snapshot.”

Nevertheless, this is “a hugely important question and we must not drop the ball. [We must] keep looking at it and maintain scientific equipoise. ... [This] reinforces the need to carry on this analysis into the future to obtain an unequivocal picture,” she emphasized.
 

Norwegian study: If there is an association, the risk is small

German Tapia, PhD, from the Norwegian Institute of Public Health, Oslo, presented the results of a study of SARS-CoV-2 infection and subsequent risk of type 1 diabetes in 1.2 million children in Norway.

Of these, 424,354 children had been infected with SARS-CoV-2, and there were 990 incident cases of type 1 diabetes.

“What we do know about COVID-19 in children is that the symptoms are mild and only a small proportion are hospitalized with more serious symptoms. But we do not know the long-term effects of COVID-19 infection because this requires a longer follow-up period,” remarked Dr. Tapia, adding that other viral infections are thought to be linked to the development of type 1 diabetes, in particular, respiratory infections.

The data were sourced from the Norwegian Emergency Preparedness Register for COVID-19, which gathers daily data updates including infections (positive and negative results for free-of-charge testing), diagnoses (primary and secondary care), vaccinations (also free of charge), prescribed medications, and basic demographics.

“We link these data using the personal identification number that every Norwegian citizen has,” explained Dr. Tapia.

He presented results from two cohorts: firstly, results in children only, including those tested for SARS-CoV-2 infection, and secondly, a full national Norwegian population cohort.

Regarding the first cohort, those under 18 years who tested positive for SARS-CoV-2 infection, from March 2020 to March 2022, had a significantly increased risk of type 1 diabetes at least 31 days after infection, with an adjusted hazard ratio of 1.63 (95% confidence interval, 1.08-2.47; P = .02). Adjustments were made for age, sex, non-Nordic country of origin, geographic area, and socioeconomic factors.

For children who developed type 1 diabetes within 30 days of a SARS-CoV-2 infection, the HR was 1.26 (95% CI, 0.72-2.19; P = .42), which did not reach statistical significance.

“The fact that fewer people developed type 1 diabetes within 30 days is not surprising because we know that type 1 diabetes develops over a long period of time,” Dr. Tapia said.

“For this reason, we would not expect to find new cases of those people who develop type 1 diabetes within 30 days of COVID-19 infection,” he explained. In these cases, “it is most likely that they already had [type 1 diabetes], and the infection probably triggered clinical symptoms, so their type 1 diabetes was discovered.”

Turning to the full population cohort and diagnoses of type 1 diabetes over 30 days after SARS-CoV-2 infection, the Norwegian researchers found an association, with an HR of 1.57 (95% CI, 1.06-2.33; P = .03), while diagnosis of type 1 diabetes at 30 days or less generated a hazard ratio of 1.22 (95% CI, 0.72-2.19; P = .42).

“So very similar results were found, and after adjustment for confounders, results were still similar,” reported Dr. Tapia.

He also conducted a similar analysis with vaccination as an exposure but found no association between vaccination against SARS-CoV-2 and diagnosis of type 1 diabetes.

“From these results, we conclude that this suggests an increase in diagnosis of type 1 diabetes after SARS-CoV-2 infection, but it must be noted that the absolute risk of developing type 1 diabetes after infection in children is low, with most children not developing the disease,” he emphasized. “There are nearly half a million children who have been infected with SARS-CoV-2 in Norway, but only a very small proportion develop type 1 diabetes.”
 

 

 

Scottish study: No association found over longer term

Dr. Colhoun and colleagues looked at the relationship between incident type 1 diabetes and SARS-CoV-2 infection in children in Scotland using e-health record linkage.

The study involved 1.8 million people under 35 years of age and found very weak, if any, evidence of an association between incident type 1 diabetes and SARS-CoV-2.

Examining data between March 2020 and November 2021, Dr. Colhoun and colleagues identified 365,080 individuals up to age 35 with at least one detected SARS-CoV-2 infection during follow-up and 1,074 who developed type 1 diabetes.

“In children under 16 years, suspected cases of type 1 diabetes are admitted to hospital, and 97% of diagnosis dates are recorded in the Scottish Care Information – Diabetes Collaboration register [SCI-Diabetes] prior to or within 2 days of the first hospital admission for type 1 diabetes,” Dr. Colhoun said, stressing the timeliness of the data.

“We found the incidence of type 1 diabetes diagnosis increased 1.2-fold in those aged 0-14 years, but we did not find any association at an individual level of COVID-19 infection over 30 days prior to a type 1 diabetes diagnosis, in this particular dataset,” she reported. In young people aged 15-34, there was a linear increase in incident type 1 diabetes from 2015 to 2021 with no pandemic increase.

Referring to the 1.2-fold increase soon after the pandemic started, she explained that, in 0- to 14-year-olds, the increase followed a drop in the preceding months prepandemic in 2019. They also found that the seasonal pattern of type 1 diabetes diagnoses remained roughly the same across the pandemic months, with typical peaks in February and September.

In the cohort of under 35s, researchers also found a rate ratio of 2.62 (95% CI, 1.81-3.78) within a 30-day window of SARS-CoV-2 infection, but beyond 30 days, no evidence was seen of an association, with a RR of 0.86 (95% CI, 0.62-1.21; P = .40), she reported.

She explained her reasons for not considering diagnoses within 30 days of COVID-19 as causative. Echoing Dr. Tapia, Dr. Colhoun said the median time from symptom onset to diagnosis of type 1 diabetes is 25 days. “This suggests that 50% have had symptoms for over 25 days at diagnosis.”

She also stressed that when they compared the timing of SARS-CoV-2 testing with diagnosis, they found a much higher rate of COVID-19 testing around diagnosis. “This was not least because everyone admitted to hospital had to have a COVID-19 test.”
 

Latest U.S. data point to a link

Meanwhile, for the new data reported in JAMA Network Open, medical student Ellen K. Kendall of Case Western Reserve University, Cleveland, matched 571,256 pediatric patients: 285,628 with COVID-19 and 285,628 with non–COVID-19 respiratory infections.

By 6 months after COVID-19, 123 patients (0.043%) had received a new diagnosis of type 1 diabetes, but only 72 (0.025%) were diagnosed with type 1 diabetes within 6 months after non–COVID-19 respiratory infection.

At 1, 3, and 6 months after infection, risk of diagnosis of type 1 diabetes was greater among those infected with SARS-CoV-2, compared with those with non–COVID-19 respiratory infection (1 month: HR, 1.96; 3 months: HR, 2.10; and 6 months: HR, 1.83), and in subgroups of patients aged 0-9 years, a group unlikely to develop type 2 diabetes.

“In this study, new type 1 diabetes diagnoses were more likely to occur among pediatric patients with prior COVID-19 than among those with other respiratory infections (or with other encounters with health systems),” noted Ms. Kendall and coauthors. “Respiratory infections have previously been associated with onset of type 1 diabetes, but this risk was even higher among those with COVID-19 in our study, raising concern for long-term, post–COVID-19 autoimmune complications among youths.”

“The increased risk of new-onset type 1 diabetes after COVID-19 adds an important consideration for risk–benefit discussions for prevention and treatment of SARS-CoV-2 infection in pediatric populations,” they concluded.

study from the Centers for Disease Control and Prevention published in January 2022, also concluded there was a link between COVID-19 and diabetes in children, but not with other acute respiratory infections. Children were 2.5 times more likely to be diagnosed with diabetes following a SARS-CoV-2 infection, it found.

However, the study has been criticized because it pooled all types of diabetes together and did not account for other health conditions, medications that can increase blood glucose levels, race, obesity, and other social determinants of health that might influence a child’s risk of acquiring COVID-19 or diabetes.

“I’ve no doubt that the CDC data were incorrect because the incidence rate for ... diabetes, even in those never exposed to COVID-19 infection, was 10 times the rate ever reported in the U.S.,” Dr. Colhoun said. “There’s no way these data are correct. I believe there was a confusion between incidence and prevalence of diabetes.”

“This paper caused a great deal of panic, especially among those who have a child with type 1diabetes, so we need to be very careful not to cause undue alarm until we have more definitive evidence in this arena,” she stressed.

However, she also acknowledged that the new Norwegian study was well conducted, and she has no methodological concerns about it, so “I think we just have to wait and see.”

Given the inconclusiveness on the issue, there is an ongoing CoviDiab registry collecting data on this very subject.

Dr. Tapia presented on behalf of lead author Dr. Gulseth, who has reported no relevant financial relationships. Dr. Colhoun also reported no relevant financial relationships.

“The fact that fewer people developed type 1 diabetes within 30 days is not surprising because we know that type 1 diabetes develops over a long period of time,” Dr. Tapia said.

“For this reason, we would not expect to find new cases of those people who develop type 1 diabetes within 30 days of COVID-19 infection,” he explained. In these cases, “it is most likely that they already had [type 1 diabetes], and the infection probably triggered clinical symptoms, so their type 1 diabetes was discovered.”

Turning to the full population cohort and diagnoses of type 1 diabetes over 30 days after SARS-CoV-2 infection, the Norwegian researchers found an association, with an HR of 1.57 (95% CI, 1.06-2.33; P = .03), while diagnosis of type 1 diabetes at 30 days or less generated a hazard ratio of 1.22 (95% CI, 0.72-2.19; P = .42).

“So very similar results were found, and after adjustment for confounders, results were still similar,” reported Dr. Tapia.

He also conducted a similar analysis with vaccination as an exposure but found no association between vaccination against SARS-CoV-2 and diagnosis of type 1 diabetes.

“From these results, we conclude that this suggests an increase in diagnosis of type 1 diabetes after SARS-CoV-2 infection, but it must be noted that the absolute risk of developing type 1 diabetes after infection in children is low, with most children not developing the disease,” he emphasized. “There are nearly half a million children who have been infected with SARS-CoV-2 in Norway, but only a very small proportion develop type 1 diabetes.”
 

 

 

Scottish study: No association found over longer term

Dr. Colhoun and colleagues looked at the relationship between incident type 1 diabetes and SARS-CoV-2 infection in children in Scotland using e-health record linkage.

The study involved 1.8 million people under 35 years of age and found very weak, if any, evidence of an association between incident type 1 diabetes and SARS-CoV-2.

Examining data between March 2020 and November 2021, Dr. Colhoun and colleagues identified 365,080 individuals up to age 35 with at least one detected SARS-CoV-2 infection during follow-up and 1,074 who developed type 1 diabetes.

“In children under 16 years, suspected cases of type 1 diabetes are admitted to hospital, and 97% of diagnosis dates are recorded in the Scottish Care Information – Diabetes Collaboration register [SCI-Diabetes] prior to or within 2 days of the first hospital admission for type 1 diabetes,” Dr. Colhoun said, stressing the timeliness of the data.

“We found the incidence of type 1 diabetes diagnosis increased 1.2-fold in those aged 0-14 years, but we did not find any association at an individual level of COVID-19 infection over 30 days prior to a type 1 diabetes diagnosis, in this particular dataset,” she reported. In young people aged 15-34, there was a linear increase in incident type 1 diabetes from 2015 to 2021 with no pandemic increase.

Referring to the 1.2-fold increase soon after the pandemic started, she explained that, in 0- to 14-year-olds, the increase followed a drop in the preceding months prepandemic in 2019. They also found that the seasonal pattern of type 1 diabetes diagnoses remained roughly the same across the pandemic months, with typical peaks in February and September.

In the cohort of under 35s, researchers also found a rate ratio of 2.62 (95% CI, 1.81-3.78) within a 30-day window of SARS-CoV-2 infection, but beyond 30 days, no evidence was seen of an association, with a RR of 0.86 (95% CI, 0.62-1.21; P = .40), she reported.

She explained her reasons for not considering diagnoses within 30 days of COVID-19 as causative. Echoing Dr. Tapia, Dr. Colhoun said the median time from symptom onset to diagnosis of type 1 diabetes is 25 days. “This suggests that 50% have had symptoms for over 25 days at diagnosis.”

She also stressed that when they compared the timing of SARS-CoV-2 testing with diagnosis, they found a much higher rate of COVID-19 testing around diagnosis. “This was not least because everyone admitted to hospital had to have a COVID-19 test.”
 

Latest U.S. data point to a link

Meanwhile, for the new data reported in JAMA Network Open, medical student Ellen K. Kendall of Case Western Reserve University, Cleveland, matched 571,256 pediatric patients: 285,628 with COVID-19 and 285,628 with non–COVID-19 respiratory infections.

By 6 months after COVID-19, 123 patients (0.043%) had received a new diagnosis of type 1 diabetes, but only 72 (0.025%) were diagnosed with type 1 diabetes within 6 months after non–COVID-19 respiratory infection.

At 1, 3, and 6 months after infection, risk of diagnosis of type 1 diabetes was greater among those infected with SARS-CoV-2, compared with those with non–COVID-19 respiratory infection (1 month: HR, 1.96; 3 months: HR, 2.10; and 6 months: HR, 1.83), and in subgroups of patients aged 0-9 years, a group unlikely to develop type 2 diabetes.

“In this study, new type 1 diabetes diagnoses were more likely to occur among pediatric patients with prior COVID-19 than among those with other respiratory infections (or with other encounters with health systems),” noted Ms. Kendall and coauthors. “Respiratory infections have previously been associated with onset of type 1 diabetes, but this risk was even higher among those with COVID-19 in our study, raising concern for long-term, post–COVID-19 autoimmune complications among youths.”

“The increased risk of new-onset type 1 diabetes after COVID-19 adds an important consideration for risk–benefit discussions for prevention and treatment of SARS-CoV-2 infection in pediatric populations,” they concluded.

study from the Centers for Disease Control and Prevention published in January 2022, also concluded there was a link between COVID-19 and diabetes in children, but not with other acute respiratory infections. Children were 2.5 times more likely to be diagnosed with diabetes following a SARS-CoV-2 infection, it found.

However, the study has been criticized because it pooled all types of diabetes together and did not account for other health conditions, medications that can increase blood glucose levels, race, obesity, and other social determinants of health that might influence a child’s risk of acquiring COVID-19 or diabetes.

“I’ve no doubt that the CDC data were incorrect because the incidence rate for ... diabetes, even in those never exposed to COVID-19 infection, was 10 times the rate ever reported in the U.S.,” Dr. Colhoun said. “There’s no way these data are correct. I believe there was a confusion between incidence and prevalence of diabetes.”

“This paper caused a great deal of panic, especially among those who have a child with type 1diabetes, so we need to be very careful not to cause undue alarm until we have more definitive evidence in this arena,” she stressed.

However, she also acknowledged that the new Norwegian study was well conducted, and she has no methodological concerns about it, so “I think we just have to wait and see.”

Given the inconclusiveness on the issue, there is an ongoing CoviDiab registry collecting data on this very subject.

Dr. Tapia presented on behalf of lead author Dr. Gulseth, who has reported no relevant financial relationships. Dr. Colhoun also reported no relevant financial relationships.

Aspirin primary prevention benefit in those with raised Lp(a)?

Wed, 10/05/2022 - 11:53

Aspirin may be of specific benefit for the primary prevention of cardiovascular disease in individuals with raised Lp(a) levels, a new study has suggested.

The study analyzed data from the ASPREE (ASPirin in Reducing Events in the Elderly) trial, which randomized 19,000 individuals aged 70 years or older without a history of cardiovascular disease to aspirin (100 mg/day) or placebo. While the main results, reported previously, showed no net benefit of aspirin in the overall population, the current analysis suggests there may be a benefit in individuals with raised Lp(a) levels.

The current analysis was published online  in the Journal of the American College of Cardiology. 

“Our study provides evidence that aspirin may specifically benefit older individuals with genotypes for elevated plasma Lp(a) in the setting of high-risk primary prevention of cardiovascular events and that overall benefit may outweigh harm related to major bleeding,” the authors, led by Paul Lacaze, PhD, Monash University, Melbourne, conclude.

They also point out that similar observations have been previously seen in another large aspirin primary prevention study conducted in younger women, the Women’s Health Study, and the current analysis provides validation of those findings.

“Our results provide new evidence to support the potential use of aspirin to target individuals with elevated Lp(a) for the primary prevention of cardiovascular events,” the researchers say.  

They acknowledge that these results would be strengthened by the use of directly measured plasma Lp(a) levels, in addition to Lp(a) genotypes.

But they add: “Nonetheless, given the lack of any currently approved therapies for targeting elevated Lp(a), our findings may have widespread clinical implications, adding evidence to the rationale that aspirin may be a viable option for reducing Lp(a)-mediated cardiovascular risk.”

Dr. Lacaze and colleagues explain that elevated plasma Lp(a) levels confer up to fourfold increased risk of cardiovascular disease, with around 20%-30% of the general population affected. Despite the high burden and prevalence of elevated plasma Lp(a), there are currently no approved pharmacologic therapies targeting this lipoprotein. Although promising candidates are in development for the secondary prevention of Lp(a)-mediated cardiovascular disease, it will be many years before these candidates are assessed for primary prevention.

For the current study, researchers analyzed data from 12,815 ASPREE participants who had undergone genotyping and compared outcomes with aspirin versus placebo in those with and without genotypes associated with elevated Lp(a) levels.

Results showed that individuals with elevated Lp(a)-associated genotypes, defined in two different ways, showed a reduction in ischemic events with aspirin versus placebo, and this benefit was not outweighed by an increased bleeding risk.

Specifically, in the placebo group, individuals who carried the rs3798220-C allele, which is known to be associated with raised Lp(a) levels, making up 3.2% of the genotyped population in the study, had an almost twofold increased risk of major adverse cardiovascular events than those not carrying this genotype. However, the risk was attenuated in the aspirin group, with carriers of the rs3798220-C allele actually having a lower rate of cardiovascular events than noncarriers.

In addition, rs3798220-C carrier status was not significantly associated with increased risk of clinically significant bleeding events in the aspirin group.

Similar results were seen with the second way of identifying patients with a high risk of elevated Lp(a) levels using a 43-variant genetic risk score (LPA-GRS).

In the whole study population, aspirin reduced major adverse cardiovascular events by 1.7 events per 1,000 person-years and increased clinically significant bleeding events by 1.7 events per 1,000 person-years, suggesting parity between overall benefit versus harm.

However, in the rs3798220-C subgroup, aspirin reduced major adverse cardiovascular events by 11.4 events per 1,000 person-years (a more than sixfold higher magnitude of cardiovascular disease risk reduction than in the overall cohort), with a bleeding risk of 3.3 events per 1,000 person-years, the researchers report.

“Hence in rs3798220-C carriers, aspirin appeared to have a net benefit of 8.1 events per 1,000 person-years,” they state.

In the highest LPA-GRS quintile, aspirin reduced major adverse cardiovascular events by 3.3 events per 1,000 person-years (approximately twofold higher magnitude of risk reduction, compared with the overall cohort), with an increase in bleeding risk of 1.6 events per 1,000 person-years (almost identical bleeding risk to the overall cohort). This shifted the benefit versus harm balance in the highest LPA-GRS quintile to a net benefit of 1.7 events per 1,000 person-years.
 

 

 

Similar findings in the Women’s Health Study

Dr. Lacaze and colleagues point out that similar results have also been seen in another large aspirin primary prevention study – the Women’s Health Study (WHS).

The WHS compared aspirin 100 mg every other day with placebo in initially healthy younger women. Previously reported results showed that women carrying the rs3798220-C variant, associated with highly elevated Lp(a) levels, had a twofold higher risk of cardiovascular events than noncarrier women in the placebo group, but this risk was reduced in the aspirin group. And there was no increased risk of bleeding in women with elevated Lp(a).

“These results, in the absence of any other randomized controlled trial evidence or approved therapy for treating Lp(a)-associated risk, have been used by some physicians as justification for prescribing aspirin in patients with elevated Lp(a),” Dr. Lacaze and colleagues note.

“In the present study of the ASPREE trial population, our results were consistent with the WHS analysis, despite randomizing older individuals (both men and women),” they add.

They say this validation of the WHS result provides evidence that a very high-risk subgroup of individuals with highly elevated Lp(a) – those carrying the rs3798220-C allele – may benefit from low-dose aspirin for the primary prevention of cardiovascular events. Further, the benefits in this subgroup specifically may outweigh any bleeding risk.

But they point out that rs3798220-C carriers comprise only a small portion of all individuals with elevated Lp(a) in the general population, while the polygenic LPA-GRS explains about 60% of the variation in directly measured plasma Lp(a) levels and has the potential advantage of being able to identify a larger group of individuals at increased risk.

The researchers note, however, that it is not clear to what extent the LPA-GRS results add further evidence to suggest that individuals with elevated Lp(a), beyond rs3798220-C carriers, may be more likely to benefit from aspirin.

“If the benefit of aspirin extends beyond very high-risk rs3798220-C carriers alone, to the broader 20%-30% of individuals with elevated Lp(a), the potential utility of aspirin for the primary prevention of cardiovascular events would increase substantially,” they say.
 

‘Very high clinical relevance’

In an accompanying editorial, Ana Devesa, MD, Borja Ibanez, MD, PhD, and Valentin Fuster, MD, PhD, The National Center for Cardiovascular Research, Madrid, say that: “[Dr.] Lacaze et al. are to be congratulated for a study of very high clinical relevance that represents a first indication for primary prevention for patients at high cardiovascular risk.”

They explain that the pathogenic mechanism of Lp(a) is believed to be a combination of prothrombotic and proatherogenic effects, and the current findings support the hypothesis that the prothrombotic mechanism of Lp(a) is mediated by platelet aggregation. 

This would explain the occurrence of thrombotic events in the presence of atherosclerosis in that elevated Lp(a) levels may induce platelet adhesion and aggregation to the activated atherosclerotic plaque, thus enhancing the atherothrombotic process. Moreover, activated platelets release several mediators that result in cell adhesion and attraction of chemokines and proinflammatory cytokines, driving an inflammatory response and mediating atherosclerosis progression, they add.

The editorialists highlight the limitations of the study already acknowledged by the authors: The analysis used genotypes rather than elevated Lp(a) levels and included only those of European ancestry, meaning the results are difficult to extrapolate to other populations.

“The next steps in clinical practice should be defined, and there are still questions to be answered,” they conclude. “Will every patient benefit from antithrombotic therapies? Should all patients who have elevated Lp(a) levels be treated with aspirin?”

The ASPREE Biobank is supported by grants from the Commonwealth Scientific and Industrial Research Organisation, Monash University, Menzies Research Institute, Australian National University, University of Melbourne, National Institutes of Health, National Health and Medical Research Council of Australia, and the Victorian Cancer Agency.

“The next steps in clinical practice should be defined, and there are still questions to be answered,” they conclude. “Will every patient benefit from antithrombotic therapies? Should all patients who have elevated Lp(a) levels be treated with aspirin?”

The bionic pancreas triumphs in pivotal trial

This transcript of Impact Factor with F. Perry Wilson has been edited for clarity.

It was 100 years ago when Leonard Thompson, age 13, received a reprieve from a death sentence. Young master Thompson had type 1 diabetes, a disease that was uniformly fatal within months of diagnosis. But he received a new treatment, insulin, from a canine pancreas. He would live 13 more years before dying at age 26 of pneumonia.

The history of type 1 diabetes since that time has been a battle on two fronts: First, the search for a cause of and cure for the disease; second, the effort to make the administration of insulin safer, more reliable, and easier.

Dr. F. Perry Wilson

The past 2 decades have seen a technological revolution in type 1 diabetes care, with continuous glucose monitors decreasing the need for painful finger sticks, and insulin pumps allowing for more precise titration of doses.

The dream, of course, has been to combine those two technologies, continuous glucose monitoring and insulin pumps, to create so-called closed-loop systems – basically an artificial pancreas – that would obviate the need for any intervention on the part of the patient, save the occasional refilling of an insulin reservoir.

We aren’t there yet, but we are closer than ever.

Closed-loop systems for insulin delivery, like the Tandem Control IQ system, are a marvel of technology, but they are not exactly hands-free. Users need to dial in settings for their insulin usage, count carbohydrates at meals, and inform the system that they are about to eat those meals to allow the algorithm to administer an appropriate insulin dose.

The perceived complexity of these systems may be responsible for why there are substantial disparities in the prescription of closed-loop systems. Kids of lower socioeconomic status are dramatically less likely to receive these advanced technologies. Providers may feel that patients with lower health literacy or social supports are not “ideal” for these technologies, even though they lead to demonstrably better outcomes.

That means that easier might be better. And a “bionic pancreas,” as reported in an article from The New England Journal of Medicine, is exactly that.

Broadly, it’s another closed-loop system. The bionic pancreas integrates with a continuous glucose monitor and administers insulin when needed. But the algorithm appears to be a bit smarter than what we have in existing devices. For example, patients do not need to provide any information about their usual insulin doses – just their body weight. They don’t need to count carbohydrates at meals – just to inform the device when they are eating, and whether the meal is the usual amount they eat, more, or less. The algorithm learns and adapts as it is used. Easy.

And in this randomized trial, easy does it.

A total of 219 participants were randomized in a 2:1 ratio to the bionic pancreas or usual diabetes care, though it was required that control participants use a continuous glucose monitor. Participants were as young as 6 years old and up to 79 years old; the majority were White and had a relatively high household income. The mean A1c was around 7.8% at baseline.

By the end of the study, the A1c was significantly improved in the bionic pancreas group, with a mean of 7.3% vs. 7.7% in the usual-care group.

This effect was most pronounced in those with a higher A1c at baseline.

People randomized to the bionic pancreas also spent more time in the target glucose range of 70-180 mg/dL.

All in all, the technology that makes it easy to manage your blood sugar, well, made it easy to manage your blood sugar.

But new technology is never without its hiccups. Those randomized to the bionic pancreas had a markedly higher rate of adverse events (244 events in 126 people compared with 10 events in 8 people in the usual-care group.)

This is actually a little misleading, though. The vast majority of these events were hyperglycemic episodes due to infusion set failures, which were reportable only in the bionic pancreas group. In other words, the patients in the control group who had an infusion set failure (assuming they were using an insulin pump at all) would have just called their regular doctor to get things sorted and not reported it to the study team.

Nevertheless, these adverse events – not serious, but common – highlight the fact that good software is not the only key to solving the closed-loop problem. We need good hardware too, hardware that can withstand the very active lives that children with type 1 diabetes deserve to live.

In short, the dream of a functional cure to type 1 diabetes, a true artificial pancreas, is closer than ever, but it’s still just a dream. With iterative advances like this, though, the reality may be here before you know it.

Meet our newest genetically engineered frenemy, herpes

Herpes to the rescue

Let’s face it: When people hear the word “herpes,” their first thoughts are not positive. But what if herpes could be a hero?

Scientists have found a way to make a strain of herpes that kills cancer because, hey, it’s 2022, and anything is possible. Trials have been going well and this seems like a safe and effective way to fight cancer.

Aunt_Spray/Thinkstock

Viruses may be one of our oldest enemies, but it’s also been said that the enemy of my enemy is my friend. So why not make herpes the enemy of cancer, thereby turning it into our friend? The genetically modified herpes virus is injected directly into tumors, where it destroys cancer cells from within. But wait, there’s more! The patient’s immune system also senses the virus and springs into action against it and the cancer in which it is residing.

During the phase 1 trial, three of the nine patients saw tumor reduction and the therapy proved safe as well. Future trials will be able to more specifically target various cancer types and make the treatment better. For once, we are rooting for you, herpes.
 

A breath of not-so-fresh air

There’s nothing quite like that first real warm day of spring. You can finally open the windows and clear out the old stuffy air that’s been hanging around all winter long. It’s a ritual that’s now backed up with some science in the form of a new study. Turns out that there’s actually a fair amount of smog in the average home. That’s right, smog’s not just for the big city anymore.

PxHere

As part of the HOMEChem project, a whole host of scientists gathered together under one roof in a typical suburban house and immediately started doing chores. Cooking, cleaning, the works. No, it wasn’t because they had trashed the place the night before. They had set up instrumentation all around the house to measure the chemical makeup of the air inside. A scientist’s idea of a wild party.

The results are perhaps not all that surprising, but interesting nonetheless. Your homemade smog certainly won’t kill you, but there’s both an increased amount and higher concentration of airborne toxins in indoor air, compared with outdoors. Benzene and formaldehyde were common, as were acrolein (a pulmonary toxicant emitted by lumber and burning fats) and isocyanic acid (which can react with proteins in the human body). The researchers noted that most of these chemicals can be removed with proper ventilation.

Although cleaning is certainly responsible for a fair share of the chemicals, cooking generally produced more toxic compounds, similar to what’s found in wildfire smoke. One of the researchers said this makes sense, since a wildfire can be considered an “extreme form of cooking.” Scientists may not know how to party, but their idea of a barbecue sounds … interesting. We’re looking forward to an upcoming study out of California: Can a 1-million acre wildfire adequately cook a ribeye steak?
 

 

 

We’re dying to try composting ... with humans, that is

We here at LOTME are not really fans of politicians, except as objects of ridicule. That is kind of fun. Whether we’re watching Fox News, listening to NPR, or reading Vladimir Putin’s fashion blog, one thing remains clear: If you want actual information, don’t ask a politician.

Recompose

There are, of course, always exceptions, and we just found one: California state representative Cristina Garcia. Rep. Garcia sponsored a bill just signed into law by Gov. Gavin Newsom that legalizes the practice of human composting, the reduction of remains by “placing bodies in individual vessels and fostering gentle transformation into a nutrient-dense soil.”

Since we’ve written about this sort of thing before – Washington was the first state to legalize the process back in 2019 – we’re more interested now in what Rep. Garcia told NBC News while describing her motivation: “I’ve always wanted to be a tree. The idea of having my family sitting under my shade one day – that brings a lot of joy.” How great is that? Tree-hugging is just not enough. Be the tree.

California is the fifth state to provide its residents with the human composting option, the other three being Colorado, Oregon, and Vermont. The process “typically involves putting a body into a steel vessel, then covering it with organic materials like straw, wood chips and alfalfa. Microbes break down the corpse and the plant matter, transforming the various components into nutrient-rich soil in roughly 30 days,” Smithsonian Magazine explained.

We just happen to have some good news for Rep. Garcia about that wanting-to-be-a-tree business. She’s already pretty close. For more on that, we go to our correspondent from beyond the grave, Carl Sagan, who shares a thought about trees. And no, we couldn’t just write out his quote here. You have to hear it in Dr. Sagan’s own voice.
 

That’ll be one pandemic with extra distress. Hold the goals

When the COVID-19 pandemic first hit it put a lot of stuff on hold for everyone. Couldn’t eat inside at your favorite restaurant, attend that long-awaited concert, or travel out of the country. Those were all pretty bad, but it was the disruption of pursuing long-term goals that seemed to have the most effect on people’s mental health.

Investigators from the University of Waterloo (Ont.) looked at how putting such goals on hold affected people’s mental well-being. The study’s 226 participants were asked about their “COVID-frozen” goals and the degree to which they were able to actively pursue each goal and how committed they were to achieving it.

What they found was that the participants’ COVID-frozen goals were associated with feelings of psychological distress, such as anxiety, depressive symptoms, stress, and lowered life satisfaction. It was only when participants were able to disengage from goal rumination that well-being was impacted positively.

“Goal rumination is compulsive and can aggravate worries and frustrations while also taking away mental resources from other goals,” Candice Hubley, lead author and a PhD candidate in psychology, said in a written statement. So in short, you’re only stressing yourself out more about something that is far off in the distance when you could be focusing more on short-term, tangible goals instead.

Now, no one is saying to give up on your goals. Just take them one at a time. You’ll have better life satisfaction and your COVID-frozen goals will thaw out before you know it.

When the COVID-19 pandemic first hit it put a lot of stuff on hold for everyone. Couldn’t eat inside at your favorite restaurant, attend that long-awaited concert, or travel out of the country. Those were all pretty bad, but it was the disruption of pursuing long-term goals that seemed to have the most effect on people’s mental health.

Investigators from the University of Waterloo (Ont.) looked at how putting such goals on hold affected people’s mental well-being. The study’s 226 participants were asked about their “COVID-frozen” goals and the degree to which they were able to actively pursue each goal and how committed they were to achieving it.

What they found was that the participants’ COVID-frozen goals were associated with feelings of psychological distress, such as anxiety, depressive symptoms, stress, and lowered life satisfaction. It was only when participants were able to disengage from goal rumination that well-being was impacted positively.

“Goal rumination is compulsive and can aggravate worries and frustrations while also taking away mental resources from other goals,” Candice Hubley, lead author and a PhD candidate in psychology, said in a written statement. So in short, you’re only stressing yourself out more about something that is far off in the distance when you could be focusing more on short-term, tangible goals instead.

Now, no one is saying to give up on your goals. Just take them one at a time. You’ll have better life satisfaction and your COVID-frozen goals will thaw out before you know it.

Out-of-state telehealth visits could help more patients if restrictions eased: Study

Article Type

Wed, 11/09/2022 - 13:23

About 5% of traditional Medicare patients who had telehealth visits were seen virtually by out-of-state clinicians in the first half of 2021, according to a new study in JAMA Health Forum.

Since then, however, many states have restored restrictions that prevent physicians who are licensed in one state from having telehealth visits with patients unless they’re licensed in the state where the patients live.

This is not fair to many people who live in areas near state borders, the authors argued. For those patients, it is much more convenient to see their primary care physician in a virtual visit from home than to travel to the doctor’s office in another state. This convenience is enjoyed by most patients who reside elsewhere in their state because they’re seeing physicians who are licensed there.

Moreover, the paper said, patients who live in rural areas and in counties with relatively few physicians per capita would also benefit from relaxed telemedicine restrictions.

Using Medicare claims data, the researchers examined the characteristics of out-of-state (OOS) telemedicine visits for the 6 months from January to June 2021. They chose that period for two reasons: by then, health care had stabilized after the chaotic early phase of the pandemic, and in most states, the relaxation of licensing rules for OOS telehealth had not yet lapsed. Earlier periods of time were also used for certain types of comparisons.

Among fee-for-service Medicare beneficiaries, the number of OOS telemedicine visits peaked at 451,086 in April 2020 and slowly fell to 175,545 in June 2021, according to the study. The fraction of OOS telehealth visits among all virtual visits was 4.5% in April 2020 and increased to 5.6% by June 2021.
 

Staying close to home

Of all beneficiaries with a telemedicine visit in the study period, 33% lived within 15 miles of a state border. That cohort accounted for 57.2% of all OOS telemedicine visits.

The highest rates of OOS telehealth visits were seen in the District of Columbia (38.5%), Wyoming (25.6%), and North Dakota (21.1%). California (1%), Texas (2%), and Massachusetts (2.1%) had the lowest rates.

Though intuitive in retrospect, the correlation of OOS telemedicine use with proximity to state borders was one of the study’s most important findings, lead author Ateev Mehrotra, MD, a professor at Harvard Medical School, Boston, said in an interview. “It makes sense,” he said. “If you’re in D.C. and you need a cardiologist, you don’t think: ‘I’ll stay in D.C.’ No, Maryland is right there, so you might use a Maryland cardiologist. Now you’re out of state, even though that office might be only half a mile away from you.”

Similar dynamics, he noted, are seen in many metropolitan areas that border on other states, such as Cincinnati; Philadelphia; and Portland, Ore.

This finding lines up with another result of the study: The majority of patients who had OOS telemedicine visits had previously seen in person the doctor who conducted the virtual visit.

Across all OOS telemedicine visits in the first half of 2021, the researchers observed a prior in-person visit between March 2019 and the date of the virtual visit with the same patient and the same clinician in 62.8% of those visits. Across all in-state telehealth visits, 75.8% of them were made by patients who had seen the same clinician in person since March 2019. This preponderance of virtual visits to clinicians whom the patients had already seen in person reflects the fact that, during the pandemic, most physicians began conducting telehealth visits with their own patients, Dr. Mehrotra said.

It also lays to rest the concern that some states have had about allowing OOS telemedicine visits to physicians not licensed in those states, he added. “They think that all these docs from far away are going to start taking care of patients they don’t even know. But our study shows that isn’t the case. Most of the time, doctors are seeing a patient who’s switching over from in-person visits to out-of-state telemedicine.”
 

 

 

More specialty care sought

The dominant conditions that patients presented with were the same in OOS telemedicine and within-state virtual visits. However, the use of OOS telemedicine was higher for some types of specialized care.

For example, the rate of OOS telemedicine use, compared with all telemedicine use, was highest for cancer care (9.8%). Drilling down to more specific conditions, the top three in OOS telemedicine visits were assessment of organ transplant (13%); male reproductive cancers, such as prostate cancer (11.3%); and graft-related issues (10.2%).

The specialty trend was also evident in the types of OOS clinicians from whom Medicare patients sought virtual care. The rates of OOS telemedicine use as a percentage of all telemedicine use in particular specialties were highest for uncommon specialties, such as hematology/oncology, rheumatology, urology, medical oncology, and orthopedic surgery (8.5%). There was less use of OOS telemedicine as a percentage of all telemedicine among more common medical specialties (6.4%), mental health specialties (4.4%), and primary care (4.4%).

Despite its relatively low showing in this category, however, behavioral health was the leading condition treated in both within-state and OOS telemedicine visits, accounting for 30.7% and 25.8%, respectively, of those encounters.

States backslide on OOS telehealth

Since the end of the study period, over half of the states have restored some or all of the restrictions on OOS telemedicine that they had lifted during the pandemic.

According to Dr. Mehrotra, 22 states have some kind of regulation in place to allow an OOS clinician to conduct telehealth visits without being licensed in the state. This varies all the way from complete reciprocity with other states’ licenses to “emergency” telemedicine licenses. The other 28 states and Washington, D.C., require an OOS telemedicine practitioner to get a state license.

Various proposals have been floated to ameliorate this situation, the JAMA paper noted. These proposals include an expansion of the Interstate Medical Licensure Compact that the Federation of State Medical Boards organized in 2014. Since the pact became effective in 2014, at least 35 states and the District of Columbia have joined it. Those states have made it simpler for physicians to gain licensure in states other than their original state of licensure. However, Mehrotra said, it’s still not easy, and not many physicians have taken advantage of it.

One new wrinkle has emerged in this policy debate as a result of the Supreme Court decision overturning Roe v. Wade, he noted. Because people are using OOS telemedicine visits to get prescriptions to abort their fetuses, “that has changed the enthusiasm level for it among many states,” he said.

Dr. Mehrotra reported personal fees from the Pew Charitable Trust, Sanofi Pasteur, and Black Opal Ventures outside the submitted work. One coauthor reported receiving grants from Patient-Centered Outcomes Research, National Institute on Aging, Roundtrip, Independence Blue Cross; personal fees or salary from RAND Corporation from Verily Life Sciences; and that the American Telemedicine Association covered a conference fee. No other disclosures were reported.

Heart failure drug a new treatment option for alcoholism? 

Article Type
Changed
Fri, 09/30/2022 - 08:05

Spironolactone, a potassium-sparing diuretic typically used to treat heart failure and hypertension, shows promise in treating alcohol use disorder (AUD), new research suggests.

Researchers at the National Institute on Drug Abuse, the National Institute on Alcohol Abuse and Alcoholism, and Yale University, New Haven, Conn., investigated the impact of spironolactone on AUD.

Initially, they studied rodents and found that spironolactone reduced binge drinking in mice and reduced self-administration of alcohol in rats without adversely affecting food or water intake or causing motor or coordination problems.

They also analyzed electronic health records of patients drawn from the United States Veterans Affairs health care system to explore potential changes in alcohol use after spironolactone treatment was initiated for other conditions and found a significant link between spironolactone treatment and reduction in self-reported alcohol consumption, with the largest effects observed among those who reported hazardous/heavy episodic alcohol use prior to starting spironolactone treatment.

“Combining findings across three species and different types of research studies, and then seeing similarities in these data, gives us confidence that we are onto something potentially important scientifically and clinically,” senior coauthor Lorenzo Leggio, MD, PhD, senior investigator in the Clinical Psychoneuroendocrinology and Neuropsychopharmacology Section, a joint NIDA and NIAAA laboratory, said in a news release.

The study was published online in Molecular Psychiatry.
 

There is a “critical need to increase the armamentarium of pharmacotherapies to treat individuals with AUD,” the authors note, adding that neuroendocrine systems involved in alcohol craving and drinking “offer promising pharmacologic targets in this regard.”

“Both our team and others have observed that patients with AUD often present with changes in peripheral hormones, including aldosterone, which plays a key role in regulating blood pressure and electrolytes,” Dr. Leggio said in an interview.

Spironolactone is a nonselective mineralocorticoid receptor (MT) antagonist. In studies in animal models, investigators said they found “an inverse correlation between alcohol drinking and the expression of the MR in the amygdala, a key brain region in the development and maintenance of AUD and addiction in general.”

Taken together, this led them to hypothesize that blocking the MR, which is the mechanism of action of spironolactone, “could be a novel pharmacotherapeutic approach for AUD,” he said.

Previous research by the same group of researchers suggested spironolactone “may be a potential new medication to treat patients with AUD.” The present study expanded on those findings and consisted of a three-part investigation.

In the current study, the investigators tested different dosages of spironolactone on binge-like alcohol consumption in male and female mice and assessed food and water intake, blood alcohol levels, motor coordination, and spontaneous locomotion.

They then tested the effects of different dosages of spironolactone injections on operant alcohol self-administration in alcohol-dependent and nondependent male and female rats, also testing blood alcohol levels and motor coordination.

Finally, they analyzed health records of veterans to examine the association between at least 60 continuous days of spironolactone treatment and self-reported alcohol consumption (measured by the Alcohol Use Disorders Identification Test-Consumption [AUDIT-C]).

Each of the spironolactone-exposed patients was matched using propensity scores with up to five unexposed patients who had reported alcohol consumption in the 2 years prior to the index date.

The final analysis included a matched cohort of 10,726 spironolactone-exposed individuals who were matched to 34,461 unexposed individuals.
 

 

 

New targets

Spironolactone reduced alcohol intake in mice drinking a sweetened alcohol solution; a 2-way ANOVA revealed a main effect of dose (F 4,52 = 9.09; P < .0001) and sex, with female mice drinking more alcohol, compared to male mice (F 1,13 = 6.05; P = .02).

Post hoc comparisons showed that spironolactone at doses of 50, 100, and 200 mg/kg significantly reduced alcohol intake (P values = .007, .002, and .0001, respectively).

In mice drinking an unsweetened alcohol solution, the 2-way repeated measures ANOVA similarly found a main effect of dose (F 4,52 = 5.77; P = .0006), but not of sex (F 1,13 = 1.41; P = .25).

Spironolactone had no effect on the mice’s intake of a sweet solution without alcohol and had no impact on the consumption of food and water or on locomotion and coordination.

In rats, a 2-way ANOVA revealed a significant spironolactone effect of dose (F 3,66 = 43.95; P < .001), with a post hoc test indicating that spironolactone at 25, 50, and 75 mg/kg reduced alcohol self-administration in alcohol-dependent and nondependent rats (all P values = .0001).

In humans, among the exposed individuals in the matched cohort, 25%, 57%, and 18% received daily doses of spironolactone of less than 25 mg/day, 25-49 mg/day, and 50 mg/day or higher, respectively, with a median follow-up time of 542 (interquartile range, 337-730) days.

The AUDIT-C scores decreased during the study period in both treatment groups, with a larger decrease in average AUDIT-C scores among the exposed vs. unexposed individuals.



“These are very exciting times because, thanks to the progress in the addiction biomedical research field, we are increasing our understanding of the mechanisms how some people develop AUD; hence we can use this knowledge to identify new targets.” The current study “is an example of these ongoing efforts,” said Dr. Leggio.

“It is important to note that [these results] are important but preliminary.” At this juncture, “it would be too premature to think about prescribing spironolactone to treat AUD,” he added.

 

Exciting findings

Commenting on the study, Joyce Besheer, PhD, professor, department of psychiatry and Bowles Center for Alcohol Studies, University of North Carolina at Chapel Hill, called the study an “elegant demonstration of translational science.”

“While clinical trials will be needed to determine whether this medication is effective at reducing drinking in patients with AUD, these findings are exciting as they suggest that spironolactone may be a promising compound and new treatment options for AUD are much needed,” said Dr. Besheer, who was not involved with the current study.

Dr. Leggio agreed. “We now need prospective, placebo-controlled studies to assess the potential safety and efficacy of spironolactone in people with AUD,” he said.

This work was supported by the National Institutes of Health and the NIAAA. Dr. Leggio, study coauthors, and Dr. Besheer declare no relevant financial relationships.

Finally, they analyzed health records of veterans to examine the association between at least 60 continuous days of spironolactone treatment and self-reported alcohol consumption (measured by the Alcohol Use Disorders Identification Test-Consumption [AUDIT-C]).

Each of the spironolactone-exposed patients was matched using propensity scores with up to five unexposed patients who had reported alcohol consumption in the 2 years prior to the index date.

The final analysis included a matched cohort of 10,726 spironolactone-exposed individuals who were matched to 34,461 unexposed individuals.
 

 

 

New targets

Spironolactone reduced alcohol intake in mice drinking a sweetened alcohol solution; a 2-way ANOVA revealed a main effect of dose (F 4,52 = 9.09; P < .0001) and sex, with female mice drinking more alcohol, compared to male mice (F 1,13 = 6.05; P = .02).

Post hoc comparisons showed that spironolactone at doses of 50, 100, and 200 mg/kg significantly reduced alcohol intake (P values = .007, .002, and .0001, respectively).

In mice drinking an unsweetened alcohol solution, the 2-way repeated measures ANOVA similarly found a main effect of dose (F 4,52 = 5.77; P = .0006), but not of sex (F 1,13 = 1.41; P = .25).

Spironolactone had no effect on the mice’s intake of a sweet solution without alcohol and had no impact on the consumption of food and water or on locomotion and coordination.

In rats, a 2-way ANOVA revealed a significant spironolactone effect of dose (F 3,66 = 43.95; P < .001), with a post hoc test indicating that spironolactone at 25, 50, and 75 mg/kg reduced alcohol self-administration in alcohol-dependent and nondependent rats (all P values = .0001).

In humans, among the exposed individuals in the matched cohort, 25%, 57%, and 18% received daily doses of spironolactone of less than 25 mg/day, 25-49 mg/day, and 50 mg/day or higher, respectively, with a median follow-up time of 542 (interquartile range, 337-730) days.

The AUDIT-C scores decreased during the study period in both treatment groups, with a larger decrease in average AUDIT-C scores among the exposed vs. unexposed individuals.



“These are very exciting times because, thanks to the progress in the addiction biomedical research field, we are increasing our understanding of the mechanisms how some people develop AUD; hence we can use this knowledge to identify new targets.” The current study “is an example of these ongoing efforts,” said Dr. Leggio.

“It is important to note that [these results] are important but preliminary.” At this juncture, “it would be too premature to think about prescribing spironolactone to treat AUD,” he added.

 

Exciting findings

Commenting on the study, Joyce Besheer, PhD, professor, department of psychiatry and Bowles Center for Alcohol Studies, University of North Carolina at Chapel Hill, called the study an “elegant demonstration of translational science.”

“While clinical trials will be needed to determine whether this medication is effective at reducing drinking in patients with AUD, these findings are exciting as they suggest that spironolactone may be a promising compound and new treatment options for AUD are much needed,” said Dr. Besheer, who was not involved with the current study.

Dr. Leggio agreed. “We now need prospective, placebo-controlled studies to assess the potential safety and efficacy of spironolactone in people with AUD,” he said.

Spironolactone, a potassium-sparing diuretic typically used to treat heart failure and hypertension, shows promise in treating alcohol use disorder (AUD), new research suggests.

Researchers at the National Institute on Drug Abuse, the National Institute on Alcohol Abuse and Alcoholism, and Yale University, New Haven, Conn., investigated the impact of spironolactone on AUD.

Initially, they studied rodents and found that spironolactone reduced binge drinking in mice and reduced self-administration of alcohol in rats without adversely affecting food or water intake or causing motor or coordination problems.

They also analyzed electronic health records of patients drawn from the United States Veterans Affairs health care system to explore potential changes in alcohol use after spironolactone treatment was initiated for other conditions and found a significant link between spironolactone treatment and reduction in self-reported alcohol consumption, with the largest effects observed among those who reported hazardous/heavy episodic alcohol use prior to starting spironolactone treatment.

“Combining findings across three species and different types of research studies, and then seeing similarities in these data, gives us confidence that we are onto something potentially important scientifically and clinically,” senior coauthor Lorenzo Leggio, MD, PhD, senior investigator in the Clinical Psychoneuroendocrinology and Neuropsychopharmacology Section, a joint NIDA and NIAAA laboratory, said in a news release.

The study was published online in Molecular Psychiatry.
 

There is a “critical need to increase the armamentarium of pharmacotherapies to treat individuals with AUD,” the authors note, adding that neuroendocrine systems involved in alcohol craving and drinking “offer promising pharmacologic targets in this regard.”

“Both our team and others have observed that patients with AUD often present with changes in peripheral hormones, including aldosterone, which plays a key role in regulating blood pressure and electrolytes,” Dr. Leggio said in an interview.

Spironolactone is a nonselective mineralocorticoid receptor (MT) antagonist. In studies in animal models, investigators said they found “an inverse correlation between alcohol drinking and the expression of the MR in the amygdala, a key brain region in the development and maintenance of AUD and addiction in general.”

Taken together, this led them to hypothesize that blocking the MR, which is the mechanism of action of spironolactone, “could be a novel pharmacotherapeutic approach for AUD,” he said.

Previous research by the same group of researchers suggested spironolactone “may be a potential new medication to treat patients with AUD.” The present study expanded on those findings and consisted of a three-part investigation.

In the current study, the investigators tested different dosages of spironolactone on binge-like alcohol consumption in male and female mice and assessed food and water intake, blood alcohol levels, motor coordination, and spontaneous locomotion.

They then tested the effects of different dosages of spironolactone injections on operant alcohol self-administration in alcohol-dependent and nondependent male and female rats, also testing blood alcohol levels and motor coordination.

Finally, they analyzed health records of veterans to examine the association between at least 60 continuous days of spironolactone treatment and self-reported alcohol consumption (measured by the Alcohol Use Disorders Identification Test-Consumption [AUDIT-C]).

Each of the spironolactone-exposed patients was matched using propensity scores with up to five unexposed patients who had reported alcohol consumption in the 2 years prior to the index date.

The final analysis included a matched cohort of 10,726 spironolactone-exposed individuals who were matched to 34,461 unexposed individuals.
