The Food and Drug Administration has approved the oral cortisol synthesis inhibitor osilodrostat (Isturisa) for the nonsurgical treatment of adults with Cushing’s disease who either are not good candidates for pituitary gland surgery – the recommended first-line therapy – or in whom the disease persists after surgery.

Cushing’s disease is a rare condition caused when a pituitary tumor releases too much of the hormone adrenocorticotropin, which in turn, triggers the adrenal gland to overproduce cortisol. The condition is associated with serious health complications, including high blood pressure, obesity, type 2 diabetes, and compromised immunity.

Osilodrostat is the first therapy approved by the FDA to tackle the overproduction of cortisol, which it does by blocking the 11-beta-hydroxylase enzyme and thus preventing cortisol synthesis, the agency said in a press release.

In November 2019, the European Medicines Agency recommended the granting of a marketing authorization for osilodrostat, also for treating adults with Cushing’s disease.

The U.S. approval was based on outcomes from a study that evaluated the drug’s safety and efficacy in 137 adults with Cushing’s disease who had undergone pituitary surgery but were not cured, or who were not surgical candidates, according the release. About three-quarters of the patients were women, and the mean age was 41 years.

All of the patients started a 24-week, single-arm, open-label period at a dose of 2 mg of osilodrostat twice daily that could be increased every 2 weeks to 30 mg twice daily.

By week 24, cortisol levels in roughly half the patients were within the normal range, and 71 patients who did not need any more dose increases and who tolerated the drug were randomized to either osilodrostat or placebo for an 8-week withdrawal study. At the end of that time, 86% of the osilodrostat patients maintained their normal-range cortisol levels, compared with 30% of those taking placebo.

Osilodrostat is taken as an oral tablet twice a day, in the morning and evening. Among the common side effects reported in the study were adrenal insufficiency, headache, vomiting, nausea, fatigue, and edema, although hypocortisolism, QTc prolongation, and elevations in adrenal hormone precursors, and androgens may also occur, according to the release.

The drug had been given an Orphan Drug Designation in recognition of its intended use in the treatment of a rare disease. The approval was granted to Novartis.

Oral hygiene may be a key factor in diabetes risk, new data from a Korean national health database suggest.

“Frequent tooth brushing may be an attenuating factor for the risk of new-onset diabetes, and the presence of periodontal disease and increased number of missing teeth may be augmenting factors,” wrote Yoonkyung Chang, MD, of the Department of Neurology, Mokdong Hospital, Ewha Womans University College of Medicine, Seoul, South Korea, and colleagues.

“Improving oral hygiene may be associated with a decreased risk of occurrence of new-onset diabetes,” they continued in an article published online in Diabetologia.

Periodontal disease involves inflammatory reactions that affect the surrounding tissues of the teeth. Inflammation, in turn, is an important cause of diabetes because it increases insulin resistance and endothelial dysfunction, Dr. Chang and colleagues explained.

They analyzed data gathered during 2003-2006 from 188,013 individuals from the Korean National Health Insurance System – Health Screening Cohort who had complete data and did not have diabetes at baseline. Oral hygiene behaviors, including frequency of tooth brushing, and dental visits or cleanings, were collected by self-report.

Over a median follow-up of 10 years, there were 31,545 new cases of diabetes, with an estimated overall 10-year event rate of 16.1%. The rate was 17.2% for those with periodontal disease at baseline, compared with 15.8% for those without, which was a significant difference even after adjustments for multiple confounders (hazard ratio, 1.09; P less than .001).

Compared with patients who had no missing teeth, the event rate for new-onset diabetes rose from 15.4% for patients with 1 missing tooth (HR, 1.08; P less than .001) to 21.4% for those with 15 or more missing teeth (HR, 1.21; P less than .001).

Professional dental cleaning did not have a significant effect after multivariate analysis. However, the number of daily tooth brushings by the individual did. Compared with brushing 0-1 times/day, those who brushed 3 or more times/day had a significantly lower risk for new-onset diabetes (HR, 0.92; P less than .001).

In subgroup analyses, periodontal disease was more strongly associated with new-onset diabetes in adults aged 51 years and younger (HR, 1.14), compared with those who were 52 years or older (HR, 1.06).

The study was supported by a grant from the Basic Science Research Program through the National Research Foundation of Korea funded by the Ministry of Education. The authors reported no relevant financial relationships.

Infant rice cereal contains lower levels of arsenic than it did in 2014, according to test results released by the Food and Drug Administration.

In April 2016, the FDA issued draft guidance calling for manufacturers of the product to reduce the level of arsenic in their cereals by establishing an action level of arsenic of 100 mcg/kg or 100 parts per billion.

Seventy-six percent of samples of infant rice cereal tested in 2018 had levels of arsenic at or below 100 parts per billion versus 47% of samples tested in 2014, according to a statement from the FDA. In 2011-2013, an even lower percentage of samples tested contained amounts of inorganic arsenic at or below the FDA’s current action level for this element, whose consumption has been associated with cancer, skin lesions, cardiovascular diseases, and diabetes.

The 2018 data is based on the testing of 149 samples of infant white and brown rice cereal samples.

“Results from our tests show that manufacturers have made significant progress in ensuring lower levels of inorganic arsenic in infant rice cereal,” Susan Mayne, PhD, director of the Center for Food Safety and Applied Nutrition, said in the FDA statement.

“Both white rice and brown rice cereals showed improvement in meeting the FDA’s 100 ppb proposed action level, but the improvement was greatest for white rice cereals, which tend to have lower levels of inorganic arsenic overall,” according to the statement.

Empagliflozin and dulaglutide became the most-prescribed drugs in their respective classes for treating type 2 diabetes in the United States from July 2013 to June 2018, new research shows.

The findings, from U.S.-based administrative claims data, were published online in Diabetes Care by Chintan V. Dave, PharmD, PhD, and colleagues.

Among patients initiating oral sodium-glucose cotransporter 2 inhibitors (SGLT2 inhibitors) over the 5-year period, empagliflozin (Jardiance, Boehringer Ingelheim/Lilly) became the most commonly prescribed glucose-lowering drug, primarily driven by an increasing proportion of patients with diabetes who had a diagnosis of myocardial infarction, stroke, or heart failure (collectively called cardiovascular disease-heart failure [CVD-HF]).

And within the subcutaneous injectable glucagonlike peptide–1 receptor (GLP-1) agonist class, initiations of dulaglutide (Trulicity, Lilly) surpassed liraglutide in 2013-2018, although patients starting liraglutide (Victoza, Novo Nordisk) were more likely to have a CVD-HF diagnosis.

“This study shows that by preferring empagliflozin, prescribers have largely reacted in accordance with the available evidence and drug labels, while other factors such as lower price, frequency of administration [dulaglutide is given weekly and liraglutide is given daily], or prior authorizations may have led prescribers to select dulaglutide over liraglutide,” Dr. Dave, of the Division of Pharmacoepidemiology and Pharmacoeconomics, Brigham and Women’s Hospital, Harvard Medical School, Boston, Massachusetts, and colleagues wrote.

Internists and endocrinologists were the most frequent prescribers of both drug classes, but cardiologists rarely prescribed them, even for patients with established CVD-HF. “As patients with co-occurring diabetes and CVD are likely to see their cardiologist, these encounters may provide an additional opportunity to optimize their treatment,” the authors emphasized.

SGLT2 inhibitors and label changes

Over the study period, the proportion of patients who had CVD-HF and who received SGLT2 inhibitors rose by 3.4 percentage points, from 8.8% to 12.2% (P trend < .001).

The proportion of overall prescriptions for SGLT2 inhibitors written by endocrinologists dropped by 12.0%, although the absolute number of SGLT2-inhibitor prescriptions written by endocrinologists increased (P < .001).

The proportion written by internists did not change (P = .58), whereas it increased slightly among cardiologists but still barely exceeded 1% (P < .001). The findings were similar for the subgroup of patients with CVD-HF who initiated SGLT2 inhibitors.

By individual agents, canagliflozin (Invokana, Janssen) prescriptions dropped by 75.1 percentage points over the study period, from 100% in 2013 to just 24.9% by 2018 (P < .001), whereas empagliflozin initiation rose by 51.7 percentage points, from 13.9% to 65.6% of all SGLT2 inhibitor initiations (P < .001).

Among those initiating empagliflozin, the proportion with CVD-HF rose by 5.3 percentage points, from 8.8% to 14.1% (P < .001), mostly after the additional indication for reducing CV events and death was added to the U.S. label in December 2016.

In contrast, there were no significant changes in the proportions of those with CVD-HF who initiated canagliflozin (P = 065), dapagliflozin (P = .87), or other medications (P = .060).

“Changes in the drug label for canagliflozin (boxed warning for amputation) and empagliflozin (for reduction in CV events and death) in 2016 likely contributed to a rapid change in prescribing preference for empagliflozin,” Dr. Dave and colleagues wrote.
 

GLP-1 agonists and frequency

Among the patients starting GLP-1 agonists, the proportion with CVD-HF increased by 3.9 percentage points, from 10.5% to 14.4% (P < .001) during the study period.

Prescriptions by endocrinologists declined as a proportion, but rose in absolute numbers (P < .001), and remained consistent for internists (> 55%; P = .12).

Prescribing of GLP-1 agonists by cardiologists remained low (< 0.5%) and was not higher for individuals with CVD-HF.

By individual GLP-1 agonist, liraglutide initiation declined by 32.1 percentage points, from 72.4% to 40.3% of GLP-1 agonist initiations (P < .001), whereas dulaglutide initiation rose by 43.8 percentage points, from 5.0% to 48.8% (P < .001). Again, these trends were similar in the subgroup of patients with CVD-HF.

The proportion of patients with CVD-HF in liraglutide initiators increased by 5.1 percentage points, from 10.5% to 15.6% (P = .018), and in exenatide initiators by 2.1 percentage points, from 10.3% to 13.8% (P = .77).

“Due to the reduced frequency of administration and possible formulary preferences, dulaglutide initiations surpassed liraglutide, the only GLP-1 agonist with evidence of CV benefit at the time,” Dr. Dave and colleagues noted.

Dulaglutide has just been granted an additional approval by the Food and Drug Administration for reducing the risk of major adverse cardiovascular events in adults with type 2 diabetes with and without established CVD or multiple CV risk factors. That makes it the first and only type 2 diabetes medicine approved to reduce the risk of CV events for both primary and secondary prevention populations.

The study was funded by the Division of Pharmacoepidemiology and Pharmacoeconomics, Department of Medicine, Brigham and Women’s Hospital, Harvard Medical School, Boston. Dr. Dave has reported receiving support from the New Jersey Alliance for Clinical and Translational Science.

By individual agents, canagliflozin (Invokana, Janssen) prescriptions dropped by 75.1 percentage points over the study period, from 100% in 2013 to just 24.9% by 2018 (P < .001), whereas empagliflozin initiation rose by 51.7 percentage points, from 13.9% to 65.6% of all SGLT2 inhibitor initiations (P < .001).

Among those initiating empagliflozin, the proportion with CVD-HF rose by 5.3 percentage points, from 8.8% to 14.1% (P < .001), mostly after the additional indication for reducing CV events and death was added to the U.S. label in December 2016.

In contrast, there were no significant changes in the proportions of those with CVD-HF who initiated canagliflozin (P = 065), dapagliflozin (P = .87), or other medications (P = .060).

“Changes in the drug label for canagliflozin (boxed warning for amputation) and empagliflozin (for reduction in CV events and death) in 2016 likely contributed to a rapid change in prescribing preference for empagliflozin,” Dr. Dave and colleagues wrote.
 

GLP-1 agonists and frequency

Among the patients starting GLP-1 agonists, the proportion with CVD-HF increased by 3.9 percentage points, from 10.5% to 14.4% (P < .001) during the study period.

Prescriptions by endocrinologists declined as a proportion, but rose in absolute numbers (P < .001), and remained consistent for internists (> 55%; P = .12).

Prescribing of GLP-1 agonists by cardiologists remained low (< 0.5%) and was not higher for individuals with CVD-HF.

By individual GLP-1 agonist, liraglutide initiation declined by 32.1 percentage points, from 72.4% to 40.3% of GLP-1 agonist initiations (P < .001), whereas dulaglutide initiation rose by 43.8 percentage points, from 5.0% to 48.8% (P < .001). Again, these trends were similar in the subgroup of patients with CVD-HF.

The proportion of patients with CVD-HF in liraglutide initiators increased by 5.1 percentage points, from 10.5% to 15.6% (P = .018), and in exenatide initiators by 2.1 percentage points, from 10.3% to 13.8% (P = .77).

“Due to the reduced frequency of administration and possible formulary preferences, dulaglutide initiations surpassed liraglutide, the only GLP-1 agonist with evidence of CV benefit at the time,” Dr. Dave and colleagues noted.

Dulaglutide has just been granted an additional approval by the Food and Drug Administration for reducing the risk of major adverse cardiovascular events in adults with type 2 diabetes with and without established CVD or multiple CV risk factors. That makes it the first and only type 2 diabetes medicine approved to reduce the risk of CV events for both primary and secondary prevention populations.

The study was funded by the Division of Pharmacoepidemiology and Pharmacoeconomics, Department of Medicine, Brigham and Women’s Hospital, Harvard Medical School, Boston. Dr. Dave has reported receiving support from the New Jersey Alliance for Clinical and Translational Science.

Valisure, an online pharmacy and analytical laboratory based in New Haven, Conn., has asked the U.S. Food and Drug Administration to request recalls of the diabetes drug metformin from 11 companies after its own testing found levels of the probable carcinogen N-nitrosodimethylamine (NDMA) exceeded those recognized by the agency as being safe, according to a petition filed with the FDA.

Several of the batches tested from a total of 22 companies contained more than 10 times the accepted 96-ng daily limit for NDMA set by the agency.

“The presence of this probable carcinogen in a medication that is taken daily by adults and adolescents for a chronic condition like diabetes, makes [these findings] particularly troubling,” the pharmacy said in the petition. It noted that NDMA is classified by the World Health Organization and the International Agency for Research on Cancer as a Group 2A compound, meaning that it is “probably carcinogenic to humans.”

The Valisure findings are in contrast to those from the FDA’s own testing of metformin from eight companies. In results released Feb. 2, the agency found no NDMA in metformin from seven of the companies, and elevations within the safe limit in metformin from the remaining company. Based on those results, the FDA did not issue a recall.

The FDA declined to comment on the petition, pending a formal written response, a spokesman said.

Valisure said in its petition that one reason it found NDMA at concerning levels, and the FDA did not, could be that the pharmacy’s testing was more thorough than the agency’s because it had used its proprietary analytical technologies in addition to FDA standard assays. The pharmacy said it also cast a wider net, testing samples from 22 companies instead of 8, as the FDA had.

“At least one company that consistently displayed high levels of NDMA in all Valisure-tested batches was a company whose metformin products, to Valisure’s knowledge, were not tested by FDA,” Valisure said in the petition.

The pharmacy tested 38 batches of metformin from 22 companies, and found 16 contaminated batches from 11 companies. Results from one company were confirmed by an independent laboratory in California.

In addition, “there was significant variability from batch to batch, even within a single company, underscoring the importance of batch-level chemical analysis and the necessity of overall increased quality surveillance of medications,” the pharmacy stated in the petition.

David Light, Valisure founder and CEO, said in a press release that the results “indicate that contaminated batches of drugs are scattered and intermixed with clean [batches] throughout the American pharmaceutical supply chain. This strongly suggests that neither the limited testing FDA is able to conduct nor the pharmaceutical companies’ self-reporting of analytical results is sufficient to protect American consumers.”

He explained in an interview that metformin contamination probably comes from poor manufacturing, as NDMA can form during the manufacturing process. Companies are supposed to have processes in place to limit its formation and to check for and remove it before products are shipped. The contaminated batches might have come from China, which makes the bulk of U.S. active pharmaceutical ingredients, he said.

Recently, Apotex and Ranbaxy Pharmaceuticals recalled specific metformin lots in Canada after Canadian health authorities requested NDMA testing. Metformin versions have also been recalled in Singapore. European health authorities are also looking into the issue, according to a Mar. 3 press release from the European Medicines Agency.

Over the past 2 years, NDMA contamination has led to recalls of angiotensin receptor blockers, such as valsartan and losartan, because of NDMA in excess of the daily limit, and ranitidine-containing products such as Zantac. Valisure said it hopes the FDA will avoid the “year-long rolling recalls” that have occurred for angiotensin receptor blockers.

Metformin, which is used to treat type 2 diabetes, is the fourth-most prescribed drug in the United States. About 80 million prescriptions were written for it during 2019, according to the press release.

Valisure launched its investigation after it found NDMA in metformin a client asked it to check.

PHOENIX – Oral estrogen therapy taken within 6 years after the onset of menopause significantly reduced progression of lipid deposition in the carotid arterial wall, compared with placebo. However, starting oral estrogen 10 years after menopause did not confer a similar benefit.

“The clinical practice of estradiol therapy has been nothing short of a roller coaster ride,” lead study author Roksana Karim, PhD, MBBS, said in an interview at the Epidemiology and Prevention/Lifestyle and Cardiometabolic Health meeting sponsored by the American Heart Association. “Clinicians have been sort of conservative in terms of prescribing estradiol therapy. But over the last 2 decades things have changed, and eventually the timing hypothesis evolved based on the final analysis of the Women’s Health Initiative results as well.”

The findings come from a secondary analysis of the Early Versus Late Intervention Trial With Estradiol (ELITE), which examined the effects of oral 17-beta-estradiol (estrogen) on the progression of early atherosclerosis and cognitive decline in healthy postmenopausal women.

In the original trial, 643 healthy postmenopausal women were randomized to receive 1 mg/day of estradiol or a placebo pill either within 6 years after the onset of menopause or more than a decade after menopause (N Engl J Med 2016;374[13]:1221-31). All study participants took estradiol or placebo daily for an average of 5 years. The study’s initial findings showed that the mean carotid intima-media thickness progression rate was decreased by 0.0034 mm per year with estradiol, compared with placebo, but only in women who initiated hormone therapy within 6 years of menopause onset.

For the current analysis, researchers led by Dr. Karim looked further into estradiol’s impact on heart health by using echogenicity to analyze lipids in the arterial wall among the ELITE participants. The main outcome of interest was gray-scale median (GSM, unitless), a qualitative measure of atherosclerosis based on echogenicity obtained by high-resolution ultrasonography of the common carotid arterial wall. Whereas higher GSM values result with plaques rich in calcium and fibrous tissue, lower GSM values indicate more lipid deposition.

Dr. Karim, an associate professor of clinical preventive medicine at the University of Southern California, Los Angeles, and colleagues assessed GSM and serum concentrations of estradiol every 6 months over a median 5-year trial period, and used linear mixed effects regression models to compare the rate of GSM progression between the randomized groups within time-since-menopause strata.

The researchers found that effect of estradiol on the annual rate of GSM progression significantly differed between women in the early and late postmenopause groups (P for interaction = .006). Specifically, the annual GSM progression rate among women in early postmenopause fell by 0.30 per year in women taking estradiol, compared with 1.41 per year in those in the placebo group (P less than .0001), indicating significantly more atherosclerosis in the placebo group. On the other hand, the annual GSM progression rate was not significantly different between the estradiol and placebo groups among the late postmenopausal women (P = .37).

“I think this should comfort clinicians in terms of prescribing estradiol therapy to women who don’t have any contraindications and who are within 6 years of menopause,” Dr. Karim said. “Accumulation of lipids is the key event for atherosclerosis progression.” She and her colleagues also observed that the positive association between mean on-trial serum estradiol levels and GSM progression rate was stronger and significant among early postmenopausal women (P = .008), compared with women in the late postmenopausal group (P = .003). However, this differential association between estradiol level and GSM progression rate was not statistically significant (P for interaction = .33).

“This study is important and raises a critical question: Is there a time period where getting hormone therapy would be most beneficial for the heart?” Nieca Goldberg, MD, medical director of the New York University women’s heart program and senior advisor for women’s health strategy at NYU Langone Health, said in an interview. “I think more studies and more analyses are needed, but we haven’t changed the indications for estradiol. We’re not giving estradiol to prevent progression of heart disease. We use estradiol hormone therapy as indicated for women who are having menopausal symptoms.”

Dr. Karim and colleagues plan to conduct a follow-up analysis from the same cohort of ELITE study participants to validate the findings by assessing lipid particles and markers of inflammation.

She reported having no financial disclosures. The study was funded by the National Institute on Aging.

When physicians gaze into their crystal balls to predict what’s coming in 2020, they see continued efforts to defund the Affordable Care Act – meaning the ACA will still be around to be defunded – but they don’t see a lot of support for universal health care, according to health care market research company InCrowd.

Expectations for universal health care came in at 18% of the 100 generalists and 101 specialists who responded to InCrowd’s fifth annual health care predictions survey, which left 82% who thought that “election outcomes will result in universal healthcare support” was somewhat or very unlikely in 2020.

One respondent, a specialist from California, commented that “the global data on universal healthcare for all shows that it results in overall improved population health. Unfortunately, we are so polarized in the US against universal healthcare driven by bias from health insurance companies and decision makers that are quick to ignore scientific data.”

This was the first time InCrowd asked physicians about universal health care, but ACA-related predictions have been included before, and all three scenarios presented were deemed to be increasingly likely, compared with 2019.

Respondents thought that federal government defunding was more likely to occur in 2020 (80%) than in 2019 (73%), but increased majorities also said that preexisting conditions coverage would continue (78% in 2020 vs. 70% in 2019) and that the ACA would remain in place (74% in 2020 vs. 60% in 2019), InCrowd reported after the survey, which was conducted from Dec. 30, 2019, to Jan. 2, 2020.

A respondent who thought the ACA will be eliminated said, “I have as many uninsured today as before the ACA. They are just different. Mainly younger patients who spend less in a year on healthcare than one month’s premium.” Another suggested that eliminateing it “will limit access to care and overload [emergency departments]. More people will die.”

Cost was addressed in a separate survey question that asked how physicians could help to reduce health care spending in 2020.

The leading answer, given by 37% of respondents, was for physicians to “inform themselves of costs and adapt cost-saving prescription practices.” Next came “limit use of expensive tests and scans” with 21%, followed by “prescribe generics when possible” at 20%, which was a substantial drop from the 38% it garnered in 2019, InCrowd noted.

“Participation in [shared savings] programs and risk-based incentive programs and pay-for-performance programs” would provide “better stewardship of resources,” a primary care physician from Michigan wrote.

When the survey turned to pharmaceutical industry predictions for 2020, cost was the major issue.

“What’s interesting about this year’s data is that we’re seeing less emphasis on the importance of bringing innovative, new therapies to market faster … versus expanding affordability, which was nearly a unanimous top priority for respondents,” Daniel S. Fitzgerald, InCrowd’s CEO and president, said in a separate statement.

“Participation in [shared savings] programs and risk-based incentive programs and pay-for-performance programs” would provide “better stewardship of resources,” a primary care physician from Michigan wrote.

When the survey turned to pharmaceutical industry predictions for 2020, cost was the major issue.

“What’s interesting about this year’s data is that we’re seeing less emphasis on the importance of bringing innovative, new therapies to market faster … versus expanding affordability, which was nearly a unanimous top priority for respondents,” Daniel S. Fitzgerald, InCrowd’s CEO and president, said in a separate statement.

When physicians gaze into their crystal balls to predict what’s coming in 2020, they see continued efforts to defund the Affordable Care Act – meaning the ACA will still be around to be defunded – but they don’t see a lot of support for universal health care, according to health care market research company InCrowd.

Expectations for universal health care came in at 18% of the 100 generalists and 101 specialists who responded to InCrowd’s fifth annual health care predictions survey, which left 82% who thought that “election outcomes will result in universal healthcare support” was somewhat or very unlikely in 2020.

One respondent, a specialist from California, commented that “the global data on universal healthcare for all shows that it results in overall improved population health. Unfortunately, we are so polarized in the US against universal healthcare driven by bias from health insurance companies and decision makers that are quick to ignore scientific data.”

This was the first time InCrowd asked physicians about universal health care, but ACA-related predictions have been included before, and all three scenarios presented were deemed to be increasingly likely, compared with 2019.

Respondents thought that federal government defunding was more likely to occur in 2020 (80%) than in 2019 (73%), but increased majorities also said that preexisting conditions coverage would continue (78% in 2020 vs. 70% in 2019) and that the ACA would remain in place (74% in 2020 vs. 60% in 2019), InCrowd reported after the survey, which was conducted from Dec. 30, 2019, to Jan. 2, 2020.

A respondent who thought the ACA will be eliminated said, “I have as many uninsured today as before the ACA. They are just different. Mainly younger patients who spend less in a year on healthcare than one month’s premium.” Another suggested that eliminateing it “will limit access to care and overload [emergency departments]. More people will die.”

Treatment with the sodium-glucose transporter 2 inhibitor dapagliflozin reduced the risk for cardiovascular disease or hospitalization for heart failure (CVD/HHF) in patients with diabetes, regardless of the duration of the disease, but had a greater protective benefit against major adverse cardiovascular events (MACE) and renal events in patients with longer disease duration, according to new findings from a post hoc analysis of the DECLARE-TIMI 58 trial.

The positive effect of dapagliflozin in patients with MACE – which includes myocardial infarction (MI), CVD, and ischemic stroke – may have been driven by lower rates of MI and ischemic stroke with the drug, compared with placebo, in patients with longer disease duration, wrote Harpreet S. Bajaj, MD, and colleagues. Their report is in Diabetes, Obesity and Metabolism (2020 Feb 23. doi: 10.1111/dom.14011).

It has been previously reported that the risk for complications in diabetes increases with increasing duration of the disease. Recent studies with SGLT-2 inhibitors have shown that the drugs improve cardiovascular and renal outcomes in diabetes, and they are recommended by the American Diabetes Association as second-line therapy in patients with atherosclerotic cardiovascular disease, chronic kidney disease, or heart failure. The European Society of Cardiology and the European Association for the Study of Diabetes recommend that patients with diabetes patients who have three or more risk factors, or those with a disease duration of more than 20 years, should be deemed very high risk and be considered for early treatment with SGLT2 inhibitors.

“The MACE benefit observed with dapagliflozin in this study in patients with diabetes duration of [more than] 20 years, clearly supports that notion,” the authors wrote.

In DECLARE-TIMI 58, 17,160 patients with type 2 diabetes received dapagliflozin or placebo and were followed for a median of 4.2 years. Of those patients, 22.4% had a disease duration of fewer than 5 years; 27.6%, a duration of 5-10 years; 23.0%, 10-15 years; 14.2%, 10-15 years; and 12.9%, more than 20 years. The median duration of disease was 11 years.

Patients in all the age groups had similar reductions in CVD/HHF, compared with placebo, with hazard ratios of 0.79 (disease duration of 5 or fewer years), 0.86, 0.92, 0.81, and 0.75 (duration of 20 years), respectively (interaction trend P = .760).

Treatment with dapagliflozin reduced the incidence of MACE, but the benefit was more apparent in patients with longer-term disease: HR, 1.08; 1.02; 0.94; 0.92; and 0.67, respectively (interaction trend P = .004). Similar trends were seen with MI (interaction trend P = .019) and ischemic stroke (interaction trend P = .015).

The researchers also reported improved benefits in renal-specific outcome with increasing disease duration, with HRs ranging from 0.79 in patients with diabetes duration of fewer than 5 years, to 0.42 in those with a duration of more than 20 years (interaction trend P = .084).

Limitations of the study include the fact that the information about diabetes duration relied on patient reports, and that the original trial was not powered for all subgroup interactions. This authors emphasized that this was a post hoc analysis and as such, should be considered hypothesis generating.

All but two of the authors reported relationships with Astra Zeneca, which funded the study, and other drug companies.

MAUI, HAWAII – Comorbid rheumatoid arthritis is a force multiplier for fragility fracture risk in patients with end-stage renal disease, Renée Peterkin-McCalman, MD, reported at the 2020 Rheumatology Winter Clinical Symposium.

Bruce Jancin/MDedge News

“Patients with RA and ESRD are at substantially increased risk of osteoporotic fragility fractures compared to the overall population of ESRD patients. So fracture prevention prior to initiation of dialysis should be a focus of care in patients with RA,” said Dr. Peterkin-McCalman, a rheumatology fellow at the Medical College of Georgia, Augusta.

She presented a retrospective cohort study of 10,706 adults who initiated hemodialysis or peritoneal dialysis for ESRD during 2005-2008, including 1,040 who also had RA. All subjects were drawn from the United States Renal Data System. The impetus for the study, Dr. Peterkin-McCalman explained in an interview, was that although prior studies have established that RA and ESRD are independent risk factors for osteoporotic fractures, the interplay between the two was previously unknown.

The risk of incident osteoporotic fractures during the first 3 years after going on renal dialysis was 14.7% in patients with ESRD only, vaulting to 25.6% in those with comorbid RA. Individuals with both RA and ESRD were at an adjusted 1.83-fold increased overall risk for new fragility fractures and at 1.85-fold increased risk for hip fracture, compared to those without RA.

Far and away the strongest risk factor for incident osteoporotic fractures in the group with RA plus ESRD was a history of a fracture sustained within 5 years prior to initiation of dialysis, with an associated 11.5-fold increased fracture risk overall and an 8.2-fold increased risk of hip fracture.

“The reason that’s important is we don’t really have any medications to reduce fracture risk once you get to ESRD. Of course, we have bisphosphonates and Prolia (denosumab) and things like that, but that’s in patients with milder CKD [chronic kidney disease] or no renal disease at all. So the goal is to identify the patients early who are at higher risk so that we can protect those bones before they get to ESRD and we have nothing left to treat them with,” she said.

In addition to a history of prevalent fracture prior to starting ESRD, the other risk factors for fracture in patients with ESRD and comorbid RA Dr. Peterkin-McCalman identified in her study included age greater than 50 years at the start of dialysis and female gender, which was associated with a twofold greater fracture risk than in men. Black patients with ESRD and RA were 64% less likely than whites to experience an incident fragility fracture. And the fracture risk was higher in patients on hemodialysis than with peritoneal dialysis.

Her study was supported by the Medical College of Georgia and a research grant from Dialysis Clinic Inc.

The risk for microvascular complications in adults with latent autoimmune diabetes increases the longer they have the disease, according a post hoc analysis of a large European database.

However, Ernesto Maddaloni, MD, of Sapienza University of Rome and University of Oxford (England), and colleagues noted that the risk is less than half that in patients with type 2 disease during the first several years after diagnosis but that, after 9 years, the risk curves cross over, and patients with latent autoimmune diabetes of adulthood (LADA) matriculate to a 25% greater risk microvascular complications than do their type 2 counterparts.

The results point to a need for tighter glycemic control in patients with latent autoimmune disease and “might have relevant implications for the understanding of the differential risk of complications between type 2 diabetes and autoimmune diabetes in general,” the researchers wrote online in The Lancet Diabetes & Endocrinology. They emphasized that the study represents the largest population of patients with latent autoimmune diabetes with the longest follow-up in a randomized controlled trial so far.

Diabetic microvascular complications are a major cause of end-stage renal disease and blindness in LADA, therefore, “implementing strict glycemic control from the time of diagnosis could reduce the later risk of microvascular complications in [these patients],” the authors wrote.

The researchers analyzed 30 years of data from the United Kingdom Prospective Diabetes Study, focusing on 564 patients with LADA and 4,464 adults with type 2 diabetes. The primary outcome was first occurrence of renal failure, death from renal disease, blindness in one eye, vitreous hemorrhage, or retinal laser treatment.

With a median follow-up of 17.3 years, 21% of all patients (1,041) developed microvascular complications, of which there were 65 renal events and 976 retinopathy events. Secondary outcomes were nephropathy and retinopathy.

The study measured incidence in 1,000 person-years and found that the incidence for the overall primary composite microvascular outcome was 5.3% for LADA and 10% for type 2 diabetes in the first 9 years after diagnosis (P = .0020), but 13.6% and 9.2%, respectively, after that (P less than .0001). That translated into adjusted hazard ratios of 0.45 for LADA, compared with type 2 diabetes, in the first 9 years (P less than .0001) and 1.25 beyond 9 years (P = .047). The incidence of retinopathy events was 5.3% for LADA and 9.6% for type 2 diabetes up to 9 years (P = .003), and 12.5% and 8.6% thereafter (P = .001). Nephropathy rates were similar in both groups at 1.3% or less.

“The lower risk of microvascular complications during the first years after the diagnosis of latent autoimmune diabetes needs further examination,” Dr. Maddaloni and colleagues wrote.

They cautioned that LADA is often misdiagnosed as a form of type 1 diabetes. “Therefore, latent autoimmune diabetes could be the right bench test for studying differences between autoimmune diabetes and type 2 diabetes, because of fewer disparities in age and disease duration than with the comparison of type 1 diabetes and type 2 diabetes,” they wrote.

In an accompanying editorial, Didac Mauricio, MD, of the Autonomous University of Barcelona, credited Dr. Maddaloni and colleagues with presenting evidence “of major relevance” in an adequately powered study that provided “a robust conclusion” about the risk of microvascular complications in latent autoimmune diabetes.

Dr. Mauricio noted that the study adds to the literature that different subgroups of type 2 diabetes patients exist and highlights the distinct characteristics of latent autoimmune diabetes. In addition, it builds on a previous study by Dr. Maddaloni and coauthors that found cardiovascular disease outcomes did not differ between latent autoimmune and type 2 diabetes (Diabetes Obes Metab. 2019;21:2115-22), he wrote. The research team’s most recent findings “emphasize the need for early identification of latent autoimmune disease,” he stated.

The findings also raise important questions about screening all patients for antibodies upon diagnosis of diabetes, he said. “I firmly believe that it is time to take action,” first, because antibody testing is likely cost-effective and cost-saving because it facilitates better-informed, more timely decisions early in the disease trajectory, and second, it has already been well documented that patients with latent autoimmune diabetes have a higher glycemic burden.

An alternative to early universal screening for antibodies would be to raise awareness, especially among general practitioners, about the importance of timely diagnosis of LADA, Dr. Mauricio added.

The study received funding from the European Foundation for the Study of Diabetes Mentorship Program, supported by AstraZeneca. Dr. Maddaloni disclosed financial relationships with Sanofi, Eli Lilly, Abbott, and AstraZeneca. Another author disclosed financial relationships with Boehringer Ingelheim, Merck, Bayer, AstraZeneca, Novartis, and Novo Nordisk.

Dr. Mauricio disclosed financial relationships with AstraZeneca, Eli Lilly, Merck Sharp & Dohme, NovoNordisk, Sanofi, Almirall, Boehringer Ingelheim, Eli Lilly, Ferrer, Janssen, Menarini, and URGO.

The risk for microvascular complications in adults with latent autoimmune diabetes increases the longer they have the disease, according a post hoc analysis of a large European database.

However, Ernesto Maddaloni, MD, of Sapienza University of Rome and University of Oxford (England), and colleagues noted that the risk is less than half that in patients with type 2 disease during the first several years after diagnosis but that, after 9 years, the risk curves cross over, and patients with latent autoimmune diabetes of adulthood (LADA) matriculate to a 25% greater risk microvascular complications than do their type 2 counterparts.

The results point to a need for tighter glycemic control in patients with latent autoimmune disease and “might have relevant implications for the understanding of the differential risk of complications between type 2 diabetes and autoimmune diabetes in general,” the researchers wrote online in The Lancet Diabetes & Endocrinology. They emphasized that the study represents the largest population of patients with latent autoimmune diabetes with the longest follow-up in a randomized controlled trial so far.

Diabetic microvascular complications are a major cause of end-stage renal disease and blindness in LADA, therefore, “implementing strict glycemic control from the time of diagnosis could reduce the later risk of microvascular complications in [these patients],” the authors wrote.

The researchers analyzed 30 years of data from the United Kingdom Prospective Diabetes Study, focusing on 564 patients with LADA and 4,464 adults with type 2 diabetes. The primary outcome was first occurrence of renal failure, death from renal disease, blindness in one eye, vitreous hemorrhage, or retinal laser treatment.

With a median follow-up of 17.3 years, 21% of all patients (1,041) developed microvascular complications, of which there were 65 renal events and 976 retinopathy events. Secondary outcomes were nephropathy and retinopathy.

The study measured incidence in 1,000 person-years and found that the incidence for the overall primary composite microvascular outcome was 5.3% for LADA and 10% for type 2 diabetes in the first 9 years after diagnosis (P = .0020), but 13.6% and 9.2%, respectively, after that (P less than .0001). That translated into adjusted hazard ratios of 0.45 for LADA, compared with type 2 diabetes, in the first 9 years (P less than .0001) and 1.25 beyond 9 years (P = .047). The incidence of retinopathy events was 5.3% for LADA and 9.6% for type 2 diabetes up to 9 years (P = .003), and 12.5% and 8.6% thereafter (P = .001). Nephropathy rates were similar in both groups at 1.3% or less.

“The lower risk of microvascular complications during the first years after the diagnosis of latent autoimmune diabetes needs further examination,” Dr. Maddaloni and colleagues wrote.

They cautioned that LADA is often misdiagnosed as a form of type 1 diabetes. “Therefore, latent autoimmune diabetes could be the right bench test for studying differences between autoimmune diabetes and type 2 diabetes, because of fewer disparities in age and disease duration than with the comparison of type 1 diabetes and type 2 diabetes,” they wrote.

In an accompanying editorial, Didac Mauricio, MD, of the Autonomous University of Barcelona, credited Dr. Maddaloni and colleagues with presenting evidence “of major relevance” in an adequately powered study that provided “a robust conclusion” about the risk of microvascular complications in latent autoimmune diabetes.

Dr. Mauricio noted that the study adds to the literature that different subgroups of type 2 diabetes patients exist and highlights the distinct characteristics of latent autoimmune diabetes. In addition, it builds on a previous study by Dr. Maddaloni and coauthors that found cardiovascular disease outcomes did not differ between latent autoimmune and type 2 diabetes (Diabetes Obes Metab. 2019;21:2115-22), he wrote. The research team’s most recent findings “emphasize the need for early identification of latent autoimmune disease,” he stated.

The findings also raise important questions about screening all patients for antibodies upon diagnosis of diabetes, he said. “I firmly believe that it is time to take action,” first, because antibody testing is likely cost-effective and cost-saving because it facilitates better-informed, more timely decisions early in the disease trajectory, and second, it has already been well documented that patients with latent autoimmune diabetes have a higher glycemic burden.

An alternative to early universal screening for antibodies would be to raise awareness, especially among general practitioners, about the importance of timely diagnosis of LADA, Dr. Mauricio added.
