Two new studies point to an ever-increasing number of young people in the United States who identify as transgender and nonbinary, with the figures doubling among 18- to 24-year-olds in one institute’s research – from 0.66% of the population in 2016 to 1.3% (398,900) in 2022.

In addition, 1.4% (300,100) of 13- to 17-year-olds identify as trans or nonbinary, according to the report from that group, the Williams Institute at the University of California, Los Angeles, School of Law.

Williams, which conducts independent research on sexual orientation and gender identity law and public policy, did not contain data on 13- to 17-year-olds in its 2016 study, so the growth in that group over the past 5+ years is not as well documented.

Overall, some 1.6 million Americans older than age 13 now identify as transgender, reported the Williams researchers.

And in a new Pew Research Center survey, 2% of adults aged 18-29 identify as transgender and 3% identify as nonbinary, a far greater number than in other age cohorts.

These reports are likely underestimates. The Human Rights Campaign estimates that some 2 million Americans of all ages identify as transgender.

The Pew survey is weighted to be representative but still has limitations, said the organization. The Williams analysis, based on responses to two CDC surveys – the Behavioral Risk Factor Surveillance System (BRFSS) and Youth Risk Behavior Survey (YRBS) – is incomplete, say researchers, because not every state collects data on gender identity.
 

Transgender identities more predominant among youth

The Williams researchers report that 18.3% of those who identified as trans were 13- to 17-year-olds; that age group makes up 7.6% of the United States population 13 and older.

And despite not having firm figures from earlier reports, they comment: “Youth ages 13-17 comprise a larger share of the transgender-identified population than we previously estimated, currently comprising about 18% of the transgender-identified population in the United State, up from 10% previously.”  

About one-quarter of those who identified as trans in the new 2022 report were aged 18-24; that age cohort accounts for 11% of Americans.

The number of older Americans who identify as trans are more proportionate to their representation in the population, according to Williams. Overall, about half of those who said they were trans were aged 25-64; that group accounts for 62% of the overall American population. Some 10% of trans-identified individuals were over age 65. About 20% of Americans are 65 or older, said the researchers.

The Pew research – based on the responses of 10,188 individuals surveyed in May – also found growing numbers of young people who identify as trans. “The share of U.S. adults who are transgender is particularly high among adults younger than 25,” reported Pew in a blog post.

In the 18- to 25-year-old group, 3.1% identified as a trans man or a trans woman, compared with just 0.5% of those ages 25-29.  

That compares to 0.3% of those aged 30-49 and 0.2% of those older than 50.
 

Racial and state-by-state variation

Similar percentages of youth aged 13-17 of all races and ethnicities in the Williams study report they are transgender, ranging from 1% of those who are Asian, to 1.3% of White youth, 1.4% of Black youth, 1.8% of American Indian or Alaska Native, and 1.8% of Latinx youth. The institute reported that 1.5% of biracial and multiracial youth identified as transgender.

The researchers said, however, that “transgender-identified youth and adults appear more likely to report being Latinx and less likely to report being White, as compared to the United States population.”

Transgender individuals live in every state, with the greatest percentage of both youth and adults in the Northeast and West, and lesser percentages in the Midwest and South, reported the Williams Institute.

Williams estimates as many as 3% of 13- to 17-year-olds in New York identify as trans, while just 0.6% of that age group in Wyoming is transgender. A total of 2%-2.5% of those aged 13-17 are transgender in Hawaii, New Mexico, Maryland, and Washington, D.C.

Among the states with higher percentages of trans-identifying 18- to 24-year-olds: Arizona (1.9%), Arkansas (3.6%), Colorado (2%), Delaware (2.4%), Illinois (1.9%), Maryland (1.9%), North Carolina (2.5%), Oklahoma (2.5%), Massachusetts (2.3%), Rhode Island (2.1%), and Washington (2%).

Despite a new meta-analysis claiming to show that testosterone replacement therapy for men with hypogonadism does not increase the risk of cardiovascular outcomes such as myocardial infarction or stroke, experts say the jury is still out.

A more definitive answer for cardiovascular safety of testosterone therapy will come from the TRAVERSE dedicated cardiovascular outcome trial, sponsored by AbbVie, which will have up to 5 years of follow-up, with results expected later this year.

The current meta-analysis by Jemma Hudson of Aberdeen (Scotland) University and colleagues was published online in The Lancet Healthy Longevity. The work will also be presented June 13 at ENDO 2022, the Endocrine Society’s annual meeting in Atlanta, Georgia, by senior author Channa Y. Jayasena, MD, PhD.

In 2014, the U.S. Food and Drug Administration mandated a label on testosterone products warning of possible increased cardiovascular risks and to reserve the therapy for symptomatic hypogonadism only. In contrast, the European Medicines Agency concluded that when hypogonadism is properly diagnosed and managed, there is currently no clear, consistent evidence that testosterone therapy causes increased cardiovascular risk.

To address this uncertainty, Dr. Hudson and colleagues formed a global collaborative to obtain individual patient data on cardiovascular outcomes from randomized controlled trials of testosterone therapy for men with hypogonadism.

They pooled data from 35 trials published from 1992 to Aug. 27, 2018, including 17 trials (3,431 patients) for which the researchers obtained patient-level data. The individual trials were 3-12 months long, except for one 3-year trial.

During a mean follow-up of 9.5 months, there was no significant increase in cardiovascular outcomes in men randomized to testosterone therapy versus placebo (odds ratio, 1.07; P = .62), nor were there any significantly increased risks of death, stroke, or different types of cardiovascular outcome, although those numbers were small.  

This is “the most comprehensive study to date investigating the safety of testosterone treatment of hypogonadism,” according to the researchers. “The current results provide some reassurance about the short-term to medium-term safety of testosterone to treat male hypogonadism,” they conclude.

However, they also acknowledge that “long-term data are needed to fully evaluate the safety of testosterone.”

Erin D. Michos, MD, coauthor of an accompanying editorial, told this news organization, “This study doesn’t say to me that low testosterone necessarily needs to be treated. It’s still not indicated in people just for a low number [for blood testosterone] with less-severe symptoms. It really comes down to each individual person, how symptomatic they are, and their cardiovascular risk.”

‘Trial is not definitive’

Dr. Michos is not the only person to be skeptical. Together with Steven Nissen, MD, an investigator for the TRAVERSE trial, she agrees that this new evidence is not yet decisive, largely because the individual trials in the meta-analysis were short and not designed as cardiovascular outcome trials.

Dr. Nissen, a cardiologist at Cleveland Clinic, added that the individual trials were heterogeneous, with “very few real cardiovascular events,” so the meta-analysis “is not definitive,” he said in an interview.

While this meta-analysis “that pooled together a lot of smaller studies is reassuring that there’s no signal of harm, it’s really inconclusive because the follow-up was really short – a mean of only 9.5 months – and you really need a larger study with longer follow up to be more conclusive,” Dr. Michos noted.

“We should have more data soon” from TRAVERSE, said Dr. Michos, from the division of cardiology, Johns Hopkins University, Baltimore, who is not involved with that study.

Meanwhile, “I don’t think [this analysis] changes the current recommendations,” she said.

“We should continue to use caution as indicated by the FDA label and only use testosterone therapy selectively in people who have true symptoms of hypogonadism,” and be cautious about using it particularly in men at higher cardiovascular risk because of family history or known personal heart disease.

On the other hand, the meta-analysis did not show harm, she noted, “so we don’t necessarily need to pull patients off therapy if they are already taking it. But I wouldn’t right now just start new patients on it unless they had a strong indication.”

“Certainly, great caution is advised regarding the use of testosterone replacement therapy in people with established atherosclerosis due to the findings of plaque progression in the testosterone trials and the excess cardiovascular events observed in the TOM trial, write Dr. Michos and fellow editorialist Matthew J. Budoff, MD, of University of California, Los Angeles, in their editorial.
 

Earlier data inconclusive

Testosterone concentrations progressively decline in men with advancing age, at about 2% per year, Dr. Michos and Dr. Budoff write. In addition, men with obesity or with diabetes have low levels of testosterone, Dr. Michos noted.

Low testosterone blood levels have been associated with insulin resistance, inflammation, dyslipidemia, and atherosclerosis. Testosterone replacement therapy has been used to increase libido, improve erectile dysfunction, and boost energy levels, mood, and muscle strength.

But it is well known that testosterone increases hematocrit, which has the potential to increase the risk of venous thromboembolism.

Two large observational studies have reported increased risks of myocardial infarction, stroke, and death in men taking testosterone, compared with nonusers, but the study designs have been widely criticized, Dr. Hudson and coauthors say in their article.  

A placebo-controlled trial was stopped early by its data- and safety-monitoring board following increased cardiovascular events in men aged 65 and older who received 6 months of testosterone. Other controlled trials have not observed these effects, but none was sufficiently powered.
 

Meta-analysis results

Dr. Hudson and colleagues performed a meta-analysis of 35 trials in 5,601 men aged 18 years and older with low baseline testosterone (≤ 350 nmol/dL) who had been randomized to testosterone replacement therapy or placebo for at least 3 months, for which there were data on mortality, stroke, and cardiovascular outcomes.

The men were a mean age of 65, had a mean body mass index of 30 kg/m², and most (88%) were White. A quarter had angina, 8% had a previous myocardial infarction, and 27% had diabetes. 

Cardiovascular and cerebrovascular outcomes were not primary outcomes.

During a mean follow-up of 9.5 months, in the 13 trials that provided this information, the rate of cardiovascular events was similar in the men who received testosterone (120/1,601, 7.5%) compared with those who received placebo (110/1,519, 7.2%).

In the 14 trials that provided this information, fewer deaths were reported during testosterone treatment (6/1,621, 0.4%) than during placebo treatment (12/1,537, 0.8%), but these numbers were too small to establish whether testosterone reduced mortality risk.

The most common cardiovascular events were arrhythmia, followed by coronary heart disease, heart failure, and myocardial infarction.

Patient age, baseline testosterone, smoking status, or diabetes status were not associated with cardiovascular risk.

The only detected adverse effects were edema and a modest lowering of HDL cholesterol.

“Men who develop sexual dysfunction, unexplained anemia, or osteoporosis should be tested for low testosterone,” senior author of the meta-analysis Dr. Jayasena said in an email to this news organization.

However, Dr. Jayasena added, “Mass screening for testosterone has no benefit in asymptomatic men.”

“Older men may still benefit from testosterone, but only if they have the clinical features [of hypogonadism] and low testosterone levels,” he concluded.  

The current study is supported by the Health Technology Assessment program of the National Institute for Health Research. The TRAVERSE trial is sponsored by AbbVie. Dr. Jayasena has reported receiving research grants from LogixX Pharma. Dr. Hudson has reported no relevant financial relationships. Disclosures for the other authors are listed in the article. Dr. Michos has reported receiving support from the Amato Fund in Women’s Cardiovascular Health at Johns Hopkins School of Medicine and serving on medical advisory boards for Novartis, Esperion, Amarin, and AstraZeneca outside the submitted work. Dr. Budoff has reported receiving grant support from General Electric.

Together with Steven Nissen, MD, an investigator for the TRAVERSE trial, she agrees that this new evidence is not yet decisive, largely because the individual trials in the meta-analysis were short and not designed as cardiovascular outcome trials.

Dr. Nissen, a cardiologist at Cleveland Clinic, added that the individual trials were heterogeneous, with “very few real cardiovascular events,” so the meta-analysis “is not definitive,” he said in an interview.

While this meta-analysis “that pooled together a lot of smaller studies is reassuring that there’s no signal of harm, it’s really inconclusive because the follow-up was really short – a mean of only 9.5 months – and you really need a larger study with longer follow up to be more conclusive,” Dr. Michos noted.

“We should have more data soon” from TRAVERSE, said Dr. Michos, from the division of cardiology, Johns Hopkins University, Baltimore, who is not involved with that study.

Meanwhile, “I don’t think [this analysis] changes the current recommendations,” she said.

“We should continue to use caution as indicated by the FDA label and only use testosterone therapy selectively in people who have true symptoms of hypogonadism,” and be cautious about using it particularly in men at higher cardiovascular risk because of family history or known personal heart disease.

On the other hand, the meta-analysis did not show harm, she noted, “so we don’t necessarily need to pull patients off therapy if they are already taking it. But I wouldn’t right now just start new patients on it unless they had a strong indication.”

“Certainly, great caution is advised regarding the use of testosterone replacement therapy in people with established atherosclerosis due to the findings of plaque progression in the testosterone trials and the excess cardiovascular events observed in the TOM trial, write Dr. Michos and fellow editorialist Matthew J. Budoff, MD, of University of California, Los Angeles, in their editorial.
 

Earlier data inconclusive

Testosterone concentrations progressively decline in men with advancing age, at about 2% per year, Dr. Michos and Dr. Budoff write. In addition, men with obesity or with diabetes have low levels of testosterone, Dr. Michos noted.

Low testosterone blood levels have been associated with insulin resistance, inflammation, dyslipidemia, and atherosclerosis. Testosterone replacement therapy has been used to increase libido, improve erectile dysfunction, and boost energy levels, mood, and muscle strength.

But it is well known that testosterone increases hematocrit, which has the potential to increase the risk of venous thromboembolism.

Two large observational studies have reported increased risks of myocardial infarction, stroke, and death in men taking testosterone, compared with nonusers, but the study designs have been widely criticized, Dr. Hudson and coauthors say in their article.  

A placebo-controlled trial was stopped early by its data- and safety-monitoring board following increased cardiovascular events in men aged 65 and older who received 6 months of testosterone. Other controlled trials have not observed these effects, but none was sufficiently powered.
 

Meta-analysis results

Dr. Hudson and colleagues performed a meta-analysis of 35 trials in 5,601 men aged 18 years and older with low baseline testosterone (≤ 350 nmol/dL) who had been randomized to testosterone replacement therapy or placebo for at least 3 months, for which there were data on mortality, stroke, and cardiovascular outcomes.

The men were a mean age of 65, had a mean body mass index of 30 kg/m², and most (88%) were White. A quarter had angina, 8% had a previous myocardial infarction, and 27% had diabetes. 

Cardiovascular and cerebrovascular outcomes were not primary outcomes.

During a mean follow-up of 9.5 months, in the 13 trials that provided this information, the rate of cardiovascular events was similar in the men who received testosterone (120/1,601, 7.5%) compared with those who received placebo (110/1,519, 7.2%).

In the 14 trials that provided this information, fewer deaths were reported during testosterone treatment (6/1,621, 0.4%) than during placebo treatment (12/1,537, 0.8%), but these numbers were too small to establish whether testosterone reduced mortality risk.

The most common cardiovascular events were arrhythmia, followed by coronary heart disease, heart failure, and myocardial infarction.

Patient age, baseline testosterone, smoking status, or diabetes status were not associated with cardiovascular risk.

The only detected adverse effects were edema and a modest lowering of HDL cholesterol.

“Men who develop sexual dysfunction, unexplained anemia, or osteoporosis should be tested for low testosterone,” senior author of the meta-analysis Dr. Jayasena said in an email to this news organization.

However, Dr. Jayasena added, “Mass screening for testosterone has no benefit in asymptomatic men.”

“Older men may still benefit from testosterone, but only if they have the clinical features [of hypogonadism] and low testosterone levels,” he concluded.

Women with polycystic ovary syndrome (PCOS) have an increased risk for several diseases and symptoms, many independent of body mass index (BMI), new research indicates.

Some diseases are linked for the first time to PCOS in this study, the authors wrote.

Researchers, led by Linda Kujanpää, MD, of the research unit for pediatrics, dermatology, clinical genetics, obstetrics, and gynecology at University of Oulu (Finland), found the morbidity risk is evident through the late reproductive years.

The paper was published online in Acta Obstetricia et Gynecologica Scandinavica.

This population-based follow-up study investigated comorbidities and medication and health care services use among women with PCOS in Finland at age 46 years via answers to a questionnaire.

The whole PCOS population (n = 280) consisted of women who reported both hirsutism and oligo/amenorrhea at age 31 (4.1%) and/or polycystic ovary morphology/PCOS at age 46 (3.1%), of which 246 replied to the 46-year questionnaire. They were compared with a control group of 1,573 women without PCOS.

Overall morbidity risk was 35% higher than for women without PCOS (risk ratio, 1.35; 95% confidence interval, 1.16-1.57). Medication use was 27% higher (RR, 1.27; 95% CI, 1.08-1.50), and the risk remained after adjusting for BMI.

Diagnoses with increased prevalence in women with PCOS were osteoarthritis, migraine, hypertension, tendinitis, and endometriosis. PCOS was also associated with autoimmune diseases and recurrent upper respiratory tract infections.

“BMI seems not to be solely responsible for the increased morbidity,” the researchers found. The average morbidity score of women with PCOS with a BMI of 25 kg/m² or higher was similar to that of women with PCOS and lower BMI.

Mindy Christianson, MD, medical director at Johns Hopkins Fertility Center and associate professor of gynecology and obstetrics at Johns Hopkins University, both in Baltimore, said in an interview that the links to diseases independent of BMI are interesting because there’s so much focus on counseling women with PCOS to lose weight.

While that message is still important, it’s important to realize that some related diseases and conditions – such as autoimmune diseases and migraine – are not driven by BMI.

“It really drives home the point that polycystic ovary syndrome is really a chronic medical condition and puts patients at risk for a number of health conditions,” she said. “Having a good primary care physician is important to help them with their overall health.”

Women with PCOS said their health was poor or very poor almost three times more often than did women in the control group.

Surprisingly few studies have looked at overall comorbidity in women with PCOS, the authors wrote.

“This should be of high priority given the high cost to society resulting from PCOS-related morbidity,” they added. As an example, they pointed out that PCOS-related type 2 diabetes alone costs an estimated $1.77 billion in the United States and £237 million ($310 million) each year in the United Kingdom.

Additionally, the focus in previous research has typically been on women in their early or mid-reproductive years, and morbidity burden data in late reproductive years are scarce.

The study population was pulled from the longitudinal Northern Finland Birth Cohort 1966 and included all pregnancies with estimated date of delivery during 1966 in two provinces of Finland (5,889 women).

Dr. Christianson said she hopes this study will spur more research on PCOS, which has been severely underfunded, especially in the United States.

Part of the reason for that is there is a limited number of subspecialists in the country who work with patients with PCOS and do research in the area. PCOS often gets lost in the research priorities of infertility, diabetes, and thyroid disease.

The message in this study that PCOS is not just a fertility issue or an obesity issue but an overall health issue with a substantial cost to the health system may help raise awareness, Dr. Christianson said.

This study was supported by grants from The Finnish Medical Foundation, The Academy of Finland, The Sigrid Juselius Foundation, The Finnish Cultural Foundation, The Jalmari and Rauha Ahokas Foundation, The Päivikki and Sakari Sohlberg Foundation, Genesis Research Trust, The Medical Research Council, University of Oulu, Oulu University Hospital, Ministry of Health and Social Affairs, National Institute for Health and Welfare, Regional Institute of Occupational Health, and the European Regional Development Fund.

Increases in use of the antipsychotic risperidone (Risperdal) are associated with small dose-related increases in both weight and blood cholesterol levels, new research suggests.

Investigators analyzed 1-year data for more than 400 patients who were taking risperidone and/or its metabolite paliperidone (Invega). Results showed increments of 1 mg of risperidone-equivalent doses were associated with an increase of 0.25% of weight within a year of follow-up.

“Although our findings report a positive and statistically significant dose-dependence of weight gain and cholesterol, both total and LDL [cholesterol], the size of the predicted changes of metabolic effects is clinically nonrelevant,” lead author Marianna Piras, PharmD, Centre for Psychiatric Neuroscience, Lausanne (Switzerland) University Hospital, said in an interview.

“Therefore, dose lowering would not have a beneficial effect on attenuating weight gain or cholesterol increases and could lead to psychiatric decompensation,” said Ms. Piras, who is also a PhD candidate in the unit of pharmacogenetics and clinical psychopharmacology at the University of Lausanne.

However, she added that because dose increments could increase risk for significant weight gain in the first month of treatment – the dose can be increased typically in a range of 1-10 grams – and strong dose increments could contribute to metabolic worsening over time, “risperidone minimum effective doses should be preferred.”

The findings were published online in the Journal of Clinical Psychiatry.
 

‘Serious public health issue’

Compared with the general population, patients with mental illness present with a greater prevalence of metabolic disorders. In addition, several psychotropic medications, including antipsychotics, can induce metabolic alterations such as weight gain, the investigators noted.

Antipsychotic-induced metabolic adverse effects “constitute a serious public health issue” because they are risk factors for cardiovascular diseases such as obesity and/or dyslipidemia, “which have been associated with a 10-year reduced life expectancy in the psychiatric population,” Ms. Piras said.

“The dose-dependence of metabolic adverse effects is a debated subject that needs to be assessed for each psychotropic drug known to induce weight gain,” she added.

Several previous studies have examined whether there is a dose-related effect of antipsychotics on metabolic parameters, “with some results suggesting that [weight gain] seems to develop even when low off-label doses are prescribed,” Ms. Piras noted.

She and her colleagues had already studied dose-related metabolic effects of quetiapine (Seroquel) and olanzapine (Zyprexa).

Risperidone is an antipsychotic with a “medium to high metabolic risk profile,” the researchers note, and few studies have examined the impact of risperidone on metabolic parameters other than weight gain.

For the current analysis, they analyzed data from a longitudinal study that included 438 patients (mean age, 40.7 years; 50.7% men) who started treatment with risperidone and/or paliperidone between 2007 and 2018.

The participants had diagnoses of schizophrenia, schizoaffective disorder, bipolar disorder, depression, “other,” or “unknown.”

Clinical follow-up periods were up to a year, but were no shorter than 3 weeks. The investigators also assessed the data at different time intervals at 1, 3, 6, and 12 months “to appreciate the evolution of the metabolic parameters.”

In addition, they collected demographic and clinical information, such as comorbidities, and measured patients’ weight, height, waist circumference, blood pressure, plasma glucose, and lipids at baseline and at 1, 3, and 12 months and then annually. Weight, waist circumference, and BP were also assessed at 2 and 6 months.

Doses of paliperidone were converted into risperidone-equivalent doses.
 

Significant weight gain over time

The mean duration of follow-up for the participants, of whom 374 were being treated with risperidone and 64 with paliperidone, was 153 days. Close to half (48.2%) were taking other psychotropic medications known to be associated with some degree of metabolic risk.

Patients were divided into two cohorts based on their daily dose intake (DDI): less than 3 mg/day (n = 201) and at least 3 mg/day (n = 237).

In the overall cohort, a “significant effect of time on weight change was found for each time point,” the investigators reported.

Small increases, big changes

Commenting on the study, Erika Nurmi, MD, PhD, associate professor in the department of psychiatry and biobehavioral sciences at the Semel Institute for Neuroscience, University of California, Los Angeles, said the study is “unique in the field.”

It “leverages real-world data from a large patient registry to ask a long-unanswered question: Are weight and metabolic adverse effects proportional to dose? Big data approaches like these are very powerful, given the large number of participants that can be included,” said Dr. Nurmi, who was not involved with the research.

However, she cautioned, the “biggest drawback [is that] these data are by nature much more complex and prone to confounding effects.”

In this case, a “critical confounder” for the study was that the majority of individuals taking higher risperidone doses were also taking other drugs known to cause weight gain, whereas the majority of those on lower risperidone doses were not. “This difference may explain the dose relationship observed,” she said.

Because real-world, big data are “valuable but also messy, conclusions drawn from them must be interpreted with caution,” Dr. Nurmi said.

She added that it is generally wise to use the lowest effective dose possible.

“Clinicians should appreciate that even small doses of antipsychotics can cause big changes in weight. Risks and benefits of medications must be carefully considered in clinical practice,” Dr. Nurmi said.

The research was funded in part by the Swiss National Research Foundation. Piras reports no relevant financial relationships. The other investigators’ disclosures are listed in the original article. Dr. Nurmi reported no relevant financial relationships, but she is an unpaid member of the Tourette Association of America’s medical advisory board and of the Myriad Genetics scientific advisory board.

Patients were divided into two cohorts based on their daily dose intake (DDI): less than 3 mg/day (n = 201) and at least 3 mg/day (n = 237).

In the overall cohort, a “significant effect of time on weight change was found for each time point,” the investigators reported.

Small increases, big changes

Commenting on the study, Erika Nurmi, MD, PhD, associate professor in the department of psychiatry and biobehavioral sciences at the Semel Institute for Neuroscience, University of California, Los Angeles, said the study is “unique in the field.”

It “leverages real-world data from a large patient registry to ask a long-unanswered question: Are weight and metabolic adverse effects proportional to dose? Big data approaches like these are very powerful, given the large number of participants that can be included,” said Dr. Nurmi, who was not involved with the research.

However, she cautioned, the “biggest drawback [is that] these data are by nature much more complex and prone to confounding effects.”

In this case, a “critical confounder” for the study was that the majority of individuals taking higher risperidone doses were also taking other drugs known to cause weight gain, whereas the majority of those on lower risperidone doses were not. “This difference may explain the dose relationship observed,” she said.

Because real-world, big data are “valuable but also messy, conclusions drawn from them must be interpreted with caution,” Dr. Nurmi said.

She added that it is generally wise to use the lowest effective dose possible.

“Clinicians should appreciate that even small doses of antipsychotics can cause big changes in weight. Risks and benefits of medications must be carefully considered in clinical practice,” Dr. Nurmi said.

A meta-analysis of 71 randomized controlled trials has found the sweet spot for omega-3 fatty acid intake for lowering blood pressure: between 2 and 3 g/day. The investigators also reported that people at higher risk for cardiovascular disease may benefit from higher daily intake of omega-3.

The study analyzed data from randomized controlled trials involving 4,973 individuals and published from 1987 to 2020. Most of the trials used a combined supplementation of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Outcomes analysis involved the impact of combined DHA-EPA at 1, 2, 3, 4, or 5 grams daily on average changes in both systolic and diastolic BP and compared them with the placebo or control groups who had a combined intake of 0 g/day.

“We found a significant nonlinear dose-response relationship for both SBP and DBP models,” wrote senior author Xinzhi Li, MD, PhD, and colleagues. Dr. Li is program director of the school of pharmacy at Macau University of Science and Technology in Taipa, China.

Most of the trials included in the meta-analysis evaluated fish oil supplements, but a number also included EPA and DHA omega-3 fatty acids consumed in food.

When the investigators analyzed studies that used an average baseline SBP of greater than 130 mm Hg, they found that increasing omega-3 supplementation resulted in strong reductions in SBP and DBP, but not so with people with baseline SBP below 130 mm Hg.

Across the entire cohort, average SBP and DBP changes averaged –2.61 (95% confidence interval, –3.57 to –1.65) and –1.64 (95% CI, –2.29 to –0.99) mm Hg for people taking 2 g/d omega-3 supplements, and –2.61 (95% CI, –3.52 to –1.69) and –1.80 (95% CI, –2.38 to –1.23) for those on 3 g/d. The changes weren’t as robust in higher and lower intake groups overall.

However, the higher the BP, the more robust the reductions. For those with SBP greater than 130 mm Hg, 3 g/d resulted in an average change of –3.22 mm Hg (95% CI, –5.21 to –1.23). In the greater than 80 mm Hg DBP group, 3 g/d of omega-3 resulted in an average –3.81 mm Hg reduction (95% CI, –4.48 to –1.87). In patients with BP greater than 140/90 and hypertension, the reductions were even more pronounced. And in patients with BP greater than 130/80, omega-3 intake of 4-5 g/d had a greater impact than 2-3 g/d, although that benefit didn’t carry over in the greater than 140/90 group.

High cholesterol was also a factor in determining the benefits of omega-3 supplementation on BP, as Dr. Li and colleagues wrote that they found “an approximately linear relationship” between hyperlipidemia and SBP, “suggesting that increasing supplementation was associated with greater reductions in SBP.” Likewise, the study found stronger effects on BP in studies with an average patient age greater than 45 years.

In 2019, the Food and Drug Administration issued an update that consuming combined EPA and DHA may lower BP in the general population and reduce the risk of hypertension, but that “the evidence is inconsistent and inconclusive.”

“However, while our study may add a layer of credible evidence, it does not meet the threshold to make an authorized health claim for omega-3 fatty acids in compliance with FDA regulations,” Dr. Li said.

The study addresses shortcomings of previous studies of omega-3 and BP and by identifying the optimal dose, Marc George, MRCP, PhD, of the Institute of Cardiovascular Science, University College, London, and Ajay Gupta, MD, PhD, of the William Harvey Research Institute at Queen Mary University, London, wrote in an accompanying editorial. “More importantly, they have demonstrated a significantly stronger and increased BP-lowering effect in higher cardiovascular risk groups, such as those with hypertension or hyperlipidemia.”

They also noted that the 2.61–mm Hg reduction in SBP the study reported is “likely to be significant” on a population level. “A 2–mm Hg reduction in SBP is estimated to reduce stroke mortality by 10% and deaths from ischemic heart disease by 7%,” they wrote. “Expressed another way, an analysis in the U.S. population using 2010 data estimates that a population-wide reduction in SBP of 2 mm Hg in those aged 45- 64 years would translate to 30,045 fewer cardiovascular events ([coronary heart disease], stroke, and heart failure).”

All U.S. patients with diabetes should undergo annual biomarker testing to allow for early diagnosis of progressive but presymptomatic heart failure, and treatment with an agent from the sodium-glucose cotransporter 2 (SGLT2) inhibitor class should expand among such patients to include everyone with stage B heart failure (“pre–heart failure”) or more advanced stages.

That’s a recommendation from an American Diabetes Association consensus report published June 1 in Diabetes Care.

The report notes that until now, “implementation of available strategies to detect asymptomatic heart failure [in patients with diabetes] has been suboptimal.” The remedy for this is that, “among individuals with diabetes, measurement of a natriuretic peptide or high-sensitivity cardiac troponin is recommended on at least a yearly basis to identify the earliest heart failure stages and to implement strategies to prevent transition to symptomatic heart failure.”

Written by a 10-member panel, chaired by Rodica Pop-Busui, MD, PhD, and endorsed by the American College of Cardiology, the document also set threshold for levels of these biomarkers that are diagnostic for a more advanced stage (stage B) of heart failure in patients with diabetes but without heart failure symptoms:

• A B-type natriuretic peptide (BNP) level of ≥50 pg/mL;
• An N-terminal pro-BNP level of ≥125 pg/mL; or
• Any high sensitivity cardiac troponin value that’s above the usual upper reference limit set at >99th percentile.

‘Inexpensive’ biomarker testing

“Addition of relatively inexpensive biomarker testing as part of the standard of care may help to refine heart failure risk prediction in individuals with diabetes,” the report says.

“Substantial data indicate the ability of these biomarkers to identify those in stage A or B [heart failure] at highest risk of progressing to symptomatic heart failure or death,” and this identification is useful because “the risk in such individuals may be lowered through targeted intervention or multidisciplinary care.”

It is “impossible to understate the importance of early recognition of heart failure” in patients with heart failure, the authors declare. However, the report also cautions that, “using biomarkers to identify and in turn reduce risk for heart failure should always be done within the context of a thoughtful clinical evaluation, supported by all information available.”

The report, written during March 2021 – March 2022, cites the high prevalence and increasing incidence of heart failure in patients with diabetes as the rationale for the new recommendations.

For a person with diabetes who receives a heart failure diagnosis, the report details several management steps, starting with an evaluation for obstructive coronary artery disease, given the strong link between diabetes and atherosclerotic cardiovascular disease.

It highlights the importance of interventions that involve nutrition, smoking avoidance, minimized alcohol intake, exercise, weight loss, and relevant social determinants of health, but focuses in greater detail on a range of pharmacologic interventions. These include treatment of hypertension for people with early-stage heart failure with an ACE inhibitor or an angiotensin receptor blocker, a thiazide-type diuretic, and a mineralocorticoid receptor antagonist, such as spironolactone or the newer, nonsteroidal agent finerenone for patients with diabetic kidney disease.

Dr. Busui of the division of metabolism, endocrinology, and diabetes at the University of Michigan, Ann Arbor, and colleagues cite recent recommendations for using guidelines-directed medical therapy to treat patients with more advanced, symptomatic stages of heart failure, including heart failure with reduced or with preserved ejection fraction.

‘Prioritize’ the SGLT2-inhibitor class

The consensus report also summarizes the roles for agents in the various classes of antidiabetes drugs now available, with particular emphasis on the role for the SGLT2-inhibitor class.

SGLT2 inhibitors “are recommended for all individuals with [diabetes and] heart failure,” it says. “This consensus recommends prioritizing the use of SGLT2 inhibitors in individuals with stage B heart failure, and that SGLT2 inhibitors be an expected element of care in all individuals with diabetes and symptomatic heart failure.”

Other agents for glycemic control that receive endorsement from the report are those in the glucagonlike peptide 1 receptor agonist class. “Despite the lack of conclusive evidence of direct heart failure risk reduction” with this class, it gets a “should be considered” designation, based on its positive effects on weight loss, blood pressure, and atherothrombotic disease.

Similar acknowledgment of potential benefit in a “should be considered” role goes to metformin. But the report turned a thumb down for both the class of dipeptidyl peptidase 4 inhibitors and the thiazolidinedione class, and said that agents from the insulin and sulfonylurea classes should be used “judiciously.”

The report did not identify any commercial funding. Several of the writing committee members listed personal commercial disclosures.

MAR DEL PLATA, ARGENTINA – Psychiatrists should prescribe metformin early to patients who experience rapid weight gain after they begin taking antipsychotic drugs, according to a new evidence-based Irish guideline for the management of this common complication in adults with psychoses who are taking medications.

The document was discussed during one of the sessions of the XXXV Argentine Congress of Psychiatry of the Association of Argentine Psychiatrists. The document also was presented by one of its authors at the European Congress on Obesity 2022.

The guideline encourages psychiatrists not to underestimate the adverse metabolic effects of their treatments and encourages them to contemplate and carry out this prevention and management strategy, commented María Delia Michat, PhD, professor of clinical psychiatry and psychopharmacology at the APSA Postgraduate Training Institute, Buenos Aires.

“Although it is always good to work as a team, it is usually we psychiatrists who coordinate the pharmacological treatment of our patients, and we have to know how to manage drugs that can prevent cardiovascular disease,” Dr. Michat said in an interview.

“The new guideline is helpful because it protocolizes the use of metformin, which is the cheapest drug and has the most evidence for antipsychotic-induced weight gain,” she added.
 

Avoiding metabolic syndrome

In patients with schizophrenia, obesity rates are 40% higher than in the general population, and 80% of patients develop weight gain after their first treatment, noted Dr. Michat. “Right away, weight gain is seen in the first month. And it is a serious problem, because patients with schizophrenia, major depression, or bipolar disorder already have an increased risk of premature mortality, especially from cardiovascular diseases, and they have an increased risk of metabolic syndrome. And we sometimes give drugs that further increase that risk,” she said.

Being overweight is a major criterion for defining metabolic syndrome. Dr. Michat noted that, among the antipsychotic drugs that increase weight the most are clozapine, olanzapine, chlorpromazine, quetiapine, and risperidone, in addition to other psychoactive drugs, such as valproic acid, lithium, mirtazapine, and tricyclic antidepressants.

Several clinical trials, such as a pioneering Chinese study from 2008, have shown the potential of metformin to mitigate the weight gain induced by this type of drug.

However, Dr. Michat noted that so far the major guidelines (for example, the Canadian Network for Mood and Anxiety Treatments [CANMAT]/International Society for Bipolar Disorders [ISBD] for bipolar disorder and the American Psychiatric Association [APA] for schizophrenia) “say very little” on how to address this complication. They propose what she defined as a “problematic” order of action in which the initial emphasis is on promoting lifestyle changes, which are difficult for these patients to carry out, as well as general proposals for changing medication (which is not simple to implement when the patient’s condition is stabilized) and eventual consultation with a clinician to start therapy with metformin or other drugs, such as liraglutide, semaglutide, and topiramate.

The new clinical practice guideline, which was published in Evidence-Based Mental Health (of the BMJ journal group), was written by a multidisciplinary team of pharmacists, psychiatrists, and mental health nurses from Ireland. It aims to fill that gap. The investigators reviewed 1,270 scientific articles and analyzed 26 of them in depth, including seven randomized clinical trials and a 2016 systematic review and meta-analysis. The authors made a “strong” recommendation, for which there was moderate-quality evidence, that for patients for whom a lifestyle intervention is unacceptable or inappropriate the use of metformin is an “alternative first-line intervention” for antipsychotic drug–induced weight gain.

Likewise, as a strong recommendation with moderate-quality evidence, the guidance encourages the use of metformin when nonpharmacologic intervention does not seem to be effective.

The guideline also says it is preferable to start metformin early for patients who gain more than 7% of their baseline weight within the first month of antipsychotic treatment. It also endorses metformin when weight gain is established.

Other recommendations include evaluating baseline kidney function before starting metformin treatment and suggest a dose adjustment when the estimated glomerular filtration rate (eGFR) is < 60 mL/min/1.73 m². The guidance says the use of metformin is contraindicated for patients in whom eGFR is <30 mL/min per 1.73 m². The proposed starting dosage is 500 mg twice per day with meals, with increments of 500 mg every 1-2 weeks until reaching a target dose of 2,000 mg/day. The guidance recommends that consideration always be given to individual tolerability and efficacy.

Treatment goals should be personalized and agreed upon with patients. In the case of early intervention, the guideline proposes initially stabilizing the weight gained or, if possible, reverse excess weight. When weight gain is established, the goal would be to lose at least 5% of the weight within the next 6 months.

The authors also recommend monitoring kidney function annually, as well as vitamin B₁₂ levels and individual tolerability and compliance. Gastrointestinal adverse effects can be managed by dose reduction or slower dose titration. The risk of lactic acidosis, which affects 4.3 per 100,000 person-years among those taking metformin, can be attenuated by adjusting the dose according to kidney function or avoiding prescribing it to patients who have a history of alcohol abuse or who are receiving treatment that may interact with the drug.
 

Validating pharmacologic management

The lead author of the new guideline, Ita Fitzgerald, a teacher in clinical pharmacy and senior pharmacist at St. Patrick’s Mental Health Services in Dublin, pointed out that there is a bias toward not using drugs for weight management and shifting the responsibility onto the patients themselves, something that is very often out of their control.

“The purpose of the guideline was to decide on a range of criteria to maximize the use of metformin, to recognize that for many people, pharmacological management is a valid and important option that could and should be more widely used and to provide precise and practical guidance to physicians to facilitate a more widespread use,” Ms. Fitzgerald said in an interview.

According to Fitzgerald, who is pursuing her doctorate at University College Cork (Ireland), one of the most outstanding results of the work is that it highlights that the main benefit of metformin is to flatten rather than reverse antipsychotic-induced weight gain and that indicating it late can nullify that effect.

“In all the recommendations, we try very hard to shift the focus from metformin’s role as a weight reversal agent to one as a weight management agent that should be used early in treatment, which is when most weight gain occurs. If metformin succeeds in flattening that increase, that’s a huge potential benefit for an inexpensive and easily accessible drug. When people have already established weight gain, metformin may not be enough and alternative treatments should be used,” she said.

In addition to its effects on weight, metformin has many other potential health benefits. Of particular importance is that it reduces hyperphagia-mediated antipsychotic-induced weight gain, Ms. Fitzgerald pointed out.

“This is subjectively very important for patients and provides a more positive experience when taking antipsychotics. Antipsychotic-induced weight gain is one of the main reasons for premature discontinuation or incomplete adherence to these drugs and therefore needs to be addressed proactively,” she concluded.

Ms. Fitzgerald and Dr. Michat have disclosed no relevant financial relationships.

MAR DEL PLATA, ARGENTINA – Psychiatrists should prescribe metformin early to patients who experience rapid weight gain after they begin taking antipsychotic drugs, according to a new evidence-based Irish guideline for the management of this common complication in adults with psychoses who are taking medications.

The document was discussed during one of the sessions of the XXXV Argentine Congress of Psychiatry of the Association of Argentine Psychiatrists. The document also was presented by one of its authors at the European Congress on Obesity 2022.

The guideline encourages psychiatrists not to underestimate the adverse metabolic effects of their treatments and encourages them to contemplate and carry out this prevention and management strategy, commented María Delia Michat, PhD, professor of clinical psychiatry and psychopharmacology at the APSA Postgraduate Training Institute, Buenos Aires.

“Although it is always good to work as a team, it is usually we psychiatrists who coordinate the pharmacological treatment of our patients, and we have to know how to manage drugs that can prevent cardiovascular disease,” Dr. Michat said in an interview.

“The new guideline is helpful because it protocolizes the use of metformin, which is the cheapest drug and has the most evidence for antipsychotic-induced weight gain,” she added.
 

Avoiding metabolic syndrome

In patients with schizophrenia, obesity rates are 40% higher than in the general population, and 80% of patients develop weight gain after their first treatment, noted Dr. Michat. “Right away, weight gain is seen in the first month. And it is a serious problem, because patients with schizophrenia, major depression, or bipolar disorder already have an increased risk of premature mortality, especially from cardiovascular diseases, and they have an increased risk of metabolic syndrome. And we sometimes give drugs that further increase that risk,” she said.

Being overweight is a major criterion for defining metabolic syndrome. Dr. Michat noted that, among the antipsychotic drugs that increase weight the most are clozapine, olanzapine, chlorpromazine, quetiapine, and risperidone, in addition to other psychoactive drugs, such as valproic acid, lithium, mirtazapine, and tricyclic antidepressants.

Several clinical trials, such as a pioneering Chinese study from 2008, have shown the potential of metformin to mitigate the weight gain induced by this type of drug.

However, Dr. Michat noted that so far the major guidelines (for example, the Canadian Network for Mood and Anxiety Treatments [CANMAT]/International Society for Bipolar Disorders [ISBD] for bipolar disorder and the American Psychiatric Association [APA] for schizophrenia) “say very little” on how to address this complication. They propose what she defined as a “problematic” order of action in which the initial emphasis is on promoting lifestyle changes, which are difficult for these patients to carry out, as well as general proposals for changing medication (which is not simple to implement when the patient’s condition is stabilized) and eventual consultation with a clinician to start therapy with metformin or other drugs, such as liraglutide, semaglutide, and topiramate.

The new clinical practice guideline, which was published in Evidence-Based Mental Health (of the BMJ journal group), was written by a multidisciplinary team of pharmacists, psychiatrists, and mental health nurses from Ireland. It aims to fill that gap. The investigators reviewed 1,270 scientific articles and analyzed 26 of them in depth, including seven randomized clinical trials and a 2016 systematic review and meta-analysis. The authors made a “strong” recommendation, for which there was moderate-quality evidence, that for patients for whom a lifestyle intervention is unacceptable or inappropriate the use of metformin is an “alternative first-line intervention” for antipsychotic drug–induced weight gain.

Likewise, as a strong recommendation with moderate-quality evidence, the guidance encourages the use of metformin when nonpharmacologic intervention does not seem to be effective.

The guideline also says it is preferable to start metformin early for patients who gain more than 7% of their baseline weight within the first month of antipsychotic treatment. It also endorses metformin when weight gain is established.

Other recommendations include evaluating baseline kidney function before starting metformin treatment and suggest a dose adjustment when the estimated glomerular filtration rate (eGFR) is < 60 mL/min/1.73 m². The guidance says the use of metformin is contraindicated for patients in whom eGFR is <30 mL/min per 1.73 m². The proposed starting dosage is 500 mg twice per day with meals, with increments of 500 mg every 1-2 weeks until reaching a target dose of 2,000 mg/day. The guidance recommends that consideration always be given to individual tolerability and efficacy.

Treatment goals should be personalized and agreed upon with patients. In the case of early intervention, the guideline proposes initially stabilizing the weight gained or, if possible, reverse excess weight. When weight gain is established, the goal would be to lose at least 5% of the weight within the next 6 months.

MILAN – The increased risk for atherosclerotic cardiovascular disease events caused by elevated lipoprotein(a) levels can potentially be precisely offset by lowering LDL cholesterol to specific levels, suggests a novel study that underscores the importance or early intervention.

The results, derived from an analysis of data on Lp(a) and LDL cholesterol levels and associated genetic risk scores in almost 500,000 individuals from the United Kingdom, have been used to develop a series of age-related targets for lowering LDL cholesterol levels to counter the risk associated with lifetime Lp(a) exposure.

Measuring Lp(a) levels can “substantially refine individual estimates of absolute risk of atherosclerotic cardiovascular disease,” said study presenter Brian A. Ference, MD, Centre for Naturally Randomized Trials, University of Cambridge (England).

This can “directly inform treatment decisions about the intensity of LDL lowering or other risk-factor modification needed to overcome the increased risk caused by Lp(a).”

Dr. Ference said this will allow clinicians to personalize the prevention of atherosclerotic cardiovascular disease and identify people “who may benefit from potent Lp(a)-lowering therapies when they become available.”

The research was presented at the European Atherosclerosis Society (EAS) 2022 congress on May 24.

In addition to producing a tabular version of the intensification of LDL-cholesterol reduction needed to overcome the increased cardiovascular risk at different levels of Lp(a), stratified by age, Dr. Ference is working with the EAS to develop an app to further deliver on that personalized prevention.

It will display an individual’s lifetime risk for myocardial infarction or stroke, with and without the inclusion of Lp(a) levels, and determine not only the percentage of increased risk caused by Lp(a), but also the amount by which LDL cholesterol needs to be lowered to overcome that risk.

“The whole rationale for this study was to say, how can we give practical advice on how to use Lp(a) to inform clinical decisions about how to individualize personal risk reduction,” Dr. Ference told this news organization.

“What the app will do is make it very easy for clinicians to, first, understand how much Lp(a) increases risk, but specifically how they can use that information to directly inform their treatment decisions.”

In addition, Dr. Ference said that it will “show patients why it’s important for them” to intensify LDL lowering to overcome their particular level of Lp(a).

Other key takeaways from the results is the importance of intervention as early as possible to minimize the impact of lifetime exposure to increased Lp(a), and that the reduction in LDL cholesterol required to achieve that remains relatively modest.

For Dr. Ference, this means ideally beginning comprehensive health checks at 30 years of age and starting lipid-lowering interventions immediately for those at risk.

“The good thing about LDL and other causes of atherosclerotic cardiovascular disease is it doesn’t really matter how you lower it,” he said, noting that it could be with diet, lifestyle interventions, or medication.
 

Handy tool

The new app could be a “handy tool to counsel patients,” Florian Kronenberg, MD, Institute of Genetic Epidemiology, Medical University of Innsbruck, Austria, told this news organization.

“We can say, look, you have high Lp(a),” he said. “This is coming from nature, from your genetics, but here we have a point where we can act on your high risk by lowering LDL further. This is important to explain to the patient,” said Dr. Kronenberg, who was not involved in the study.

He emphasized that it is crucial to get across the idea of an individual’s global risk, with not just Lp(a) or cholesterol levels influencing their likelihood of cardiovascular events, but also their age, blood pressure, smoking status, and underlying genetic risk.

Dr. Kronenberg said the current data will be helpful in explaining to clinicians why they should lower LDL-cholesterol levels when a patients had high Lp(a), again centered on the idea of lowering their global risk.

During his presentation, Dr. Ference noted that an increase in Lp(a) levels is associated with a log-linear increase in atherosclerotic cardiovascular disease that is proportional to the absolute, rather than relative, magnitude of Lp(a) increase.

“Unfortunately, unlike other proteins,” he continued, diet and exercise do not affect levels, and there are currently no effective therapies to lower the risks associated with increased Lp(a) concentrations.

“For that reason,” he said, the 2019 ESC/EAS guidelines for the management of dyslipidemias, on which Dr. Ference was a coauthor, “recommend that we intensify life risk-factor modification in persons with elevated risks.”

However, he added, “this guidance is not specific enough to be useful, and that has created a great deal of inertia among clinicians,” with some concluding that they don’t need to measure Lp(a) “because there’s nothing they can do for it.”

Until the development of novel therapies that directly target Lp(a), the authors sought to quantify the amount of LDL lowering needed to “overcome the increased risk caused by Lp(a),” he said.

They studied data on 455,765 individuals from the UK Biobank who did not have a history of cardiovascular events, diabetes, or any cancer before the age of 30. They also had LDL cholesterol levels below 5 mmol/L at the time of enrollment to exclude people with presumed familial hypercholesterolemia.

The researchers used an Lp(a) genetic risk score based on the variants rs10455872 and rs3798220 and an LDL instrumental variable genetic score comprised of 100 variants to randomly categorize individuals with average Lp(a) levels, higher Lp(a) levels, or higher Lp(a) and lower LDL-cholesterol levels.

The data showed that, with elevated absolute levels of measured Lp(a) and with elevated genetic risk scores, there was a progressive increase in the lifetime risk for major coronary events.

When looking at the combination of both increased Lp(a) levels and lower LDL-cholesterol levels, they found that the increase in risk for major coronary events at Lp(a) of 123 nmol/L could be offset by a reduction in LDL-cholesterol levels of 19.5 mg/dL.

For people with an Lp(a) level of 251 nmol/L, the increase in risk for major coronary events was offset by a reduction in LDL-cholesterol levels of 36.1 mg/dL.

Furthermore, the researchers found that the magnitude of intensification of LDL-cholesterol lowering needed to overcome the risk caused by elevated Lp(a) levels varied by age.

For example, in individuals with an Lp(a) level of 220 nmol/L, the reduction in LDL-cholesterol levels needed to offset the risk for major coronary events was calculated to be 0.8 mmol/L if lipid-lowering was started at 30 years of age, rising to 0.9 mmol/L if started at 40 years, 1.2 mmol/L if started at 50 years, and 1.5 mmol/L if started at 60 years.

This, Dr. Ference said, suggests that “diet and lifestyle modification is unlikely to be an effective strategy if started later.”

No funding was declared. Dr. Ference declared relationships with Amgen, Novartis, Merck, Esperion Therapeutics, Pfizer, Regeneron, Sanofi, AstraZeneca, Eli Lilly, Novo Nordisk, The Medicines Company, Mylan, Daiichi Sankyo, Viatris, Ionis Pharmaceuticals, dalCOR, CiVi Pharma, and KrKa Pharmaceuticals. Dr. Kronenberg declared relationships with Amgen, Novartis, and Kaneka.

Other key takeaways from the results is the importance of intervention as early as possible to minimize the impact of lifetime exposure to increased Lp(a), and that the reduction in LDL cholesterol required to achieve that remains relatively modest.

For Dr. Ference, this means ideally beginning comprehensive health checks at 30 years of age and starting lipid-lowering interventions immediately for those at risk.

“The good thing about LDL and other causes of atherosclerotic cardiovascular disease is it doesn’t really matter how you lower it,” he said, noting that it could be with diet, lifestyle interventions, or medication.
 

Handy tool

The new app could be a “handy tool to counsel patients,” Florian Kronenberg, MD, Institute of Genetic Epidemiology, Medical University of Innsbruck, Austria, told this news organization.

“We can say, look, you have high Lp(a),” he said. “This is coming from nature, from your genetics, but here we have a point where we can act on your high risk by lowering LDL further. This is important to explain to the patient,” said Dr. Kronenberg, who was not involved in the study.

He emphasized that it is crucial to get across the idea of an individual’s global risk, with not just Lp(a) or cholesterol levels influencing their likelihood of cardiovascular events, but also their age, blood pressure, smoking status, and underlying genetic risk.

Dr. Kronenberg said the current data will be helpful in explaining to clinicians why they should lower LDL-cholesterol levels when a patients had high Lp(a), again centered on the idea of lowering their global risk.

During his presentation, Dr. Ference noted that an increase in Lp(a) levels is associated with a log-linear increase in atherosclerotic cardiovascular disease that is proportional to the absolute, rather than relative, magnitude of Lp(a) increase.

“Unfortunately, unlike other proteins,” he continued, diet and exercise do not affect levels, and there are currently no effective therapies to lower the risks associated with increased Lp(a) concentrations.

“For that reason,” he said, the 2019 ESC/EAS guidelines for the management of dyslipidemias, on which Dr. Ference was a coauthor, “recommend that we intensify life risk-factor modification in persons with elevated risks.”

However, he added, “this guidance is not specific enough to be useful, and that has created a great deal of inertia among clinicians,” with some concluding that they don’t need to measure Lp(a) “because there’s nothing they can do for it.”

Until the development of novel therapies that directly target Lp(a), the authors sought to quantify the amount of LDL lowering needed to “overcome the increased risk caused by Lp(a),” he said.

They studied data on 455,765 individuals from the UK Biobank who did not have a history of cardiovascular events, diabetes, or any cancer before the age of 30. They also had LDL cholesterol levels below 5 mmol/L at the time of enrollment to exclude people with presumed familial hypercholesterolemia.

The researchers used an Lp(a) genetic risk score based on the variants rs10455872 and rs3798220 and an LDL instrumental variable genetic score comprised of 100 variants to randomly categorize individuals with average Lp(a) levels, higher Lp(a) levels, or higher Lp(a) and lower LDL-cholesterol levels.

The data showed that, with elevated absolute levels of measured Lp(a) and with elevated genetic risk scores, there was a progressive increase in the lifetime risk for major coronary events.

When looking at the combination of both increased Lp(a) levels and lower LDL-cholesterol levels, they found that the increase in risk for major coronary events at Lp(a) of 123 nmol/L could be offset by a reduction in LDL-cholesterol levels of 19.5 mg/dL.

For people with an Lp(a) level of 251 nmol/L, the increase in risk for major coronary events was offset by a reduction in LDL-cholesterol levels of 36.1 mg/dL.

Furthermore, the researchers found that the magnitude of intensification of LDL-cholesterol lowering needed to overcome the risk caused by elevated Lp(a) levels varied by age.

For example, in individuals with an Lp(a) level of 220 nmol/L, the reduction in LDL-cholesterol levels needed to offset the risk for major coronary events was calculated to be 0.8 mmol/L if lipid-lowering was started at 30 years of age, rising to 0.9 mmol/L if started at 40 years, 1.2 mmol/L if started at 50 years, and 1.5 mmol/L if started at 60 years.

This, Dr. Ference said, suggests that “diet and lifestyle modification is unlikely to be an effective strategy if started later.”

No funding was declared. Dr. Ference declared relationships with Amgen, Novartis, Merck, Esperion Therapeutics, Pfizer, Regeneron, Sanofi, AstraZeneca, Eli Lilly, Novo Nordisk, The Medicines Company, Mylan, Daiichi Sankyo, Viatris, Ionis Pharmaceuticals, dalCOR, CiVi Pharma, and KrKa Pharmaceuticals. Dr. Kronenberg declared relationships with Amgen, Novartis, and Kaneka.

Essure implants arrived on the market in 2002 as permanent contraception for women older than age 45 years with children. They were recalled in 2017. Presented as an alternative to laparoscopic tubal ligation, this medical device resulted in rare side effects affecting thousands of women, most notably the nervous system, cardiovascular system, endocrine system, and musculoskeletal system.

Implant analysis protocol

A team from Lyon, France, studied the wear debris from these medical devices and their possible toxic health effects. They discovered that tin could be the cause of the implant’s toxicity. “My research focuses on a variety of medical devices, mostly joint replacements, and more specifically, hip replacements. I look at how these materials behave in humans and how the wear debris affects the body,” explained Ana Maria Trunfio-Sfarghiu, bioengineering expert and research associate with the French National Center for Scientific Research at the Lyon National Institute of Applied Sciences’ Contact and Structure Mechanics Laboratory.

“The problems with Essure implants started with a woman who had been using one for about 10 years and was experiencing side effects such as trouble concentrating and focusing, significant vaginal bleeding, extreme tiredness, hair loss, etc. She had the implant removed, and we retrieved it from her gynecologist and analyzed it alongside other implants,” said Ms. Trunfio-Sfarghiu.

“Together with the hospital, we set up an implant analysis protocol. We visited hospital teams to demonstrate how to prepare the biopsies, embedded in paraffin blocks, before sending them to us for analysis. We gave the same specimen preparation instructions for all subjects,” Ms. Trunfio-Sfarghiu explained.

After a year of clinical analysis, the Journal of Trace Elements in Medicine and Biology published an article about 18 cases.
 

Implant weld corrosion

The Essure implant measures a few centimeters long and resembles a small spring. Once it is released inside the fallopian tube, its goal is to create inflammation and block the tube. It triggers fibrosis, which prevents the sperm from reaching the egg. Premarketing tests had shown that the fibrosis surrounding the implant would keep it from moving. However, the pharmaceutical company hadn’t assessed the mechanical integrity of the spring weld, which was made of silver-tin.

During their analysis in collaboration with the Minapath laboratory, Ms. Trunfio-Sfarghiu’s team found that the weld had corroded and that tin particles had been released into the subjects’ bodies. “The study included about 40 women, and we found tin in all of them,” said Ms. Trunfio-Sfarghiu.

This weld corrosion has several possible consequences. “When the implant degrades, it can travel anywhere in the pelvis, like a needle moving through the body with no apparent destination. The surgeons who operate to remove it describe similar surgeries in military medicine when the patient has been hit by a bullet!”
 

Organotin toxicity

Although tin is not especially toxic for the body when ingested, it can bind to organic compounds if it passes through to the blood. “When tin binds to a carbon atom, it becomes organotin, a neurotoxin,” said Ms. Trunfio-Sfarghiu.

She said that this organotin can travel to the brain and trigger symptoms like those found in patients with Essure implants. “For the time being, there is insufficient data to assert that we found organotin in all subjects. Another more in-depth study would be needed to assess migration to the brain. For the past 2 years, we have tried to obtain academic funding to continue our research, so far without success. Academic and political authorities seem to be a bit scared of what we’ve found,” said Ms. Trunfio-Sfarghiu.

For her, “it’s how the implant was marketed that is problematic. The implant was designed to create local inflammation, inflammation in itself being difficult to control. Some women need to have their entire uterus and ovaries removed to resolve problems caused by the implant.”
 

Harm in the United States

Ms. Trunfio-Sfarghiu’s research has helped American victims obtain acknowledgment of their suffering in the United States. “But the harm caused to women by defective implants has yet to be acknowledged in France,” she added.

She explained that Essure was recalled in 2017 because sales were poor, not because it was deemed dangerous. Her conclusion? “No implant that creates inflammation should be authorized, especially if there is a surgical alternative, which there is here: tubal ligation.”

“Grandma’s workouts may have made you healthier.” The title and accompanying photo of a pair of well-worn women’s running shoes caught my eye immediately. For whatever reason, we are a family of exercisers. My wife has competed in several triathlons and won two of them. With her I have cycled across the United States. It has not surprised us that all three of our children have run at least one marathon. I have always viewed their continued devotion to an active lifestyle and their healthy bodies as a tribute to the benefits of our attempts at parenting by example. We certainly didn’t coach them, lecture them, or run family boot camps on weekends and school vacations.

I had never really given much thought as to whether their grandparents also may have played any role in their affinity for physical activity until I read that article. Apparently, my mother was a gifted athlete as a young woman. I have seen photos of her playing tennis, skiing, and diving and heard stories, but I never saw her do any of these activities except a single perfect swan dive when I must have been 8 or 9 years old.

Similarly, scrapbooks reveal that my mother-in-law had an active sports life in high school. But we never saw any evidence of her athletic activity save a devotion to a gentle backstroke in the cold Maine waters during the summer. My wife and I and our children never saw these grandmothers do anything more sporting or physically taxing than single-handedly preparing a full Thanksgiving dinner. How could their exercise habits have influenced the health of their grandchildren?

A team of researchers at the Joslin Diabetes Center in Boston found that female mice who were given the opportunity to exercise produced offspring that had lower fat mass, higher bone mineral density, and insulin levels usually associated with a lower risk of type 2 diabetes. And, in a bit of a surprise, the next generation of offspring accrued a similar benefit even though its mothers were not exercising. The role of exercise in the fathers was eliminated by experimental design.

So it appears that the first-generation offspring’s gametes and hence the third generation was being exposed in utero to something generated by the grandmothers’ exercise. It does not appear to be a behavior pattern that is passed on. It may have to do with epigenetics. Searching for this unknown factor is ongoing and broad based.

Obviously, similar studies in humans are not on the drawing board. Our reproductive cycle is significantly longer than the 2 years of the mouse. However, looking at their current data, the researchers feel comfortable encouraging a mother to exercise during pregnancy as long as it is compatible with the particulars of her obstetrical course. It would be unkind and without basis in fact to blame your mother’s or your mother-in-law’s sedentary behavior for your child’s poor metabolic health. However, it is reasonable to point out to women considering pregnancy that, in addition to avoiding alcohol and smoking, a good dose of exercise during pregnancy will benefit their children. You can point out that it may even benefit their grandchildren. And of course, once the baby is born and a mother feels comfortable returning to her exercise regime, she should go for it. Remind her also that parenting by example is still the best way to do it.
