Metabolic syndrome raises dementia risk in under-60s
The more components of metabolic syndrome a person has in midlife seems to raise their risk of dementia, although that relationship seems to go away after age 70, a post hoc analysis of data from a major European cohort study has found.
A team of European researchers reported online in the journal Diabetes Care that the follow-up of the Whitehall II cohort study, a study of more than 10,000 civil servants in London that was established in the late 1980s, also found that cardiovascular disease (CVD) may only partially contribute to the risk of dementia in study participants.
They found that each additional metabolic syndrome component before age 60 years was linked to a 13% rise in the risk of dementia (hazard ratio, 1.13; 95% confidence interval [CI], 1.05-1.23) and, from age 60 to 70, the risk rose 8% (HR, 1.08; 95% CI, 1.00-1.16). However, in people aged 70 years and older, the relationship wasn’t statistically significant (HR, 1.04; 95% CI, 0.96-1.13]).
The study used “the latest harmonized definition” of metabolic syndrome; that is, participants were classified as having metabolic syndrome if they had three or more of the five components. As lead author Marcos D. Machado-Fragua, PhD, noted in an email interview, those components are abdominal obesity, high triglycerides, low HDL cholesterol levels, high blood pressure, and high fasting glucose.
“Our research question was on the association between metabolic syndrome and late-life dementia. We found that the presence of one metabolic syndrome component and the presence of metabolic risk before age 60, but not after, is associated with higher risk of dementia,” said Dr. Machado-Fragua, a post-doctoral researcher at the French Institute for Health and Medical Research in Paris.
The study cohort consisted of 10,308 London-based civil servants aged 35-55 years. Every 4-5 years after enrollment, from 1991 through 2016, they completed a questionnaire and had a clinical examination. The U.K. National Health Service electronic health record system tracked outcomes for all but 10 participants through March 2019.
The study identified the individual metabolic syndrome components that posed the highest risk for dementia in these three age groups:
- Age < 60 years: elevated waist circumference (HR 1.39 [95% CI 1.07, 1.81]), low HDL-C, (HR 1.30 [95% CI 1.02, 1.66]), and elevated blood pressure (HR 1.34 [95% CI 1.09, 1.63]).
- Age 60-70 years: low HDL-C (HR 1.26 [95% CI 1.02, 1.57]) and elevated fasting glucose (HR 1.40 [95% CI 1.12, 1.74]).
- Age >70 years: elevated fasting glucose (HR 1.38 [95% CI 1.07, 1.79]).
The study found that the dementia risk was significantly high in study participants under age 60 who had at least one (HR 1.99 [95% CI 1.08, 3.66]) or two (HR 1.69 [95% CI 1.12, 2.56]) metabolic syndrome components even when they didn’t have CVD.
“The present study adds to the understanding of the association between metabolic syndrome and dementia due to three novel features,” Dr. Machado-Fragua said. “First, we tested alternative thresholds to define ‘high metabolic risk,’ and findings show increased risk of dementia to start with the presence of one metabolic syndrome component. Second, assessment of metabolic syndrome components in midlife and later life allowed the examination of the role of age at prevalence of metabolic risk for incident dementia at older ages. Third, our findings showed high dementia risk in those free of cardiovascular disease during follow-up, suggesting that the association between high metabolic risk and incident dementia is not fully explained by cardiovascular disease.”
Dr. Machado-Fragua added, “For now, a cure for dementia remains elusive, making it important to think of prevention strategies. Our findings support targeting the components of the metabolic syndrome in midlife, even in those who have fewer than three of the metabolic syndrome components.”
Applicability ‘confusing’
In an interview, Yehuda Handelsman, MD, questioned the applicability of the study findings in the clinic. “Metabolic syndrome is a clinical manifestation of insulin resistance,” he said. “The more metabolic syndrome criteria a person has, the more insulin resistant that person will be. There is literature that is [suggesting] that insulin resistance is an important cause of dementia.”
The finding of a higher dementia risk before age 70, compared to afterward, makes the applicability “even more confusing,” he said. The results are even more muddled for U.S. physicians, who have moved away from the term metabolic syndrome in favor of cardiometabolic syndrome, said Dr. Handelsman, medical director and principal investigator at the Metabolic Institute of America and president of the Diabetes CardioRenal & Metabolism Institute, both in Tarzana, Calif.
Confusion also surrounds one of the components of metabolic syndrome: Waist circumference, per the harmonized definition the study used, and body mass index, which the more traditional definition uses.
Nonetheless, metabolic syndrome can be used as “kind of a risk calculator” for CVD, diabetes, and dementia, he said. One strength of the study, Dr. Handelsman said, is its size and scope, following 28 years of data. But a weakness was its observational design. “It doesn’t evaluate any true intervention to modify risk,” he said.
Dr. Machado-Fragua and coauthors have no disclosures.

New update focuses on NAFLD in lean people
Ongoing follow-up and lifestyle interventions are needed in lean patients with nonalcoholic fatty liver disease (NAFLD), suggests a panel of experts in a recent review.
They also urge screening for NAFLD in individuals who are older than 40 years with type 2 diabetes, even if they are not overweight.
NAFLD is a leading cause of chronic liver disease that affects more than 25% of the United States and worldwide populations, note lead author Michelle T. Long, MD, Boston Medical Center, Boston University, and colleagues.
They add that around one-quarter of those affected have nonalcoholic steatohepatitis, which is associated with significant morbidity and mortality due to complications of liver cirrhosis, hepatic decompensation, and hepatocellular carcinoma.
Although NAFLD occurs primarily in individuals with obesity or type 2 diabetes, between 7%-20% have a lean body habitus, they write.
There are differences in rates of disease progression, associated conditions, and diagnostic and management approaches between lean and non-lean patients, the authors note, but there is limited guidance on the appropriate clinical evaluation of the former group.
The American Gastroenterological Association therefore commissioned an expert review to provide best practice advice on key clinical issues relating to the diagnosis, risk stratification, and treatment of NAFLD in lean individuals.
Their review was published online in Gastroenterology.
Evidence-based approaches
The 15 best practice advice statements covered a wide range of clinical areas, first defining lean as a body mass index (BMI) less than 25 in non-Asian persons and less than 23 in Asian persons.
The authors go on to stipulate, for example, that lean individuals in the general population should not be screened for NAFLD but that screening should be considered for individuals older than 40 years with type 2 diabetes.
More broadly, they write that the condition should be considered in lean individuals with metabolic diseases, such as type 2 diabetes, dyslipidemia, and hypertension, as well as elevated values on liver biochemical tests or incidentally noted hepatic steatosis.
After other causes of liver diseases are ruled out, the authors note that clinicians should consider liver biopsy as the reference test if uncertainties remain about liver injury causes and/or liver fibrosis staging.
They also write that the NAFLD fibrosis score and Fibrosis-4 score, along with imaging techniques, may be used as alternatives to biopsy for staging and during follow-up.
The authors, who provide a diagnosis and management algorithm to aid clinicians, suggest that lean patients with NAFLD follow lifestyle interventions, such as exercise, diet modification, and avoidance of fructose- and sugar-sweetened drinks, to achieve weight loss of 3%-5%.
Vitamin E may be considered, they continue, in patients with biopsy-confirmed nonalcoholic steatohepatitis but without type 2 diabetes or cirrhosis. Additionally, oral pioglitazone may be considered in lean persons with biopsy-confirmed nonalcoholic steatohepatitis without cirrhosis.
In contrast, they write that the role of glucagonlike peptide 1 agonists and sodium-glucose cotransporter 2 inhibitors requires further investigation.
The advice also says that lean patients with NAFLD should be routinely evaluated for comorbid conditions, such as type 2 diabetes, dyslipidemia, and hypertension, and risk-stratified for hepatic fibrosis to identify those with advanced fibrosis or cirrhosis.
For lean patients with NAFLD and clinical markers compatible with liver cirrhosis, twice-yearly surveillance for hepatocellular carcinoma is also advised.
Fatty liver disease in lean people with metabolic conditions
Approached for comment, Liyun Yuan, MD, PhD, assistant professor of clinical medicine, University of Southern California, Los Angeles, said it is very important to have uniform guidelines for general practitioners and other specialties on NAFLD in lean individuals.
Dr. Yuan, who was not involved in the review, told this news organization that it is crucial to raise awareness of NAFLD, just like awareness of breast cancer screening among women of a certain age was increased, so that individuals are screened for metabolic conditions regardless of whether they have obesity or overweight.
Zobair Younossi, MD, MPH, professor of medicine, Virginia Commonwealth University, Inova Campus, Falls Church, Va., added that there is a lack of awareness that NAFLD occurs in lean individuals, especially in those who have diabetes.
He said in an interview that although it is accurate to define individuals as being lean in terms of their BMI, the best way is to look not only at BMI but also at waist circumference.
Dr. Younossi said that he and his colleagues have shown that when BMI is combined with waist circumference, the prediction of mortality risk in NAFLD is affected, such that lean individuals with an obese waist circumference have a higher risk for all-cause mortality.
Dr. Long is supported in part by the National Institute of Diabetes and Digestive and Kidney Diseases, Doris Duke Charitable Foundation, Gilead Sciences Research Scholars Award, Boston University School of Medicine Department of Medicine Career Investment Award, and Boston University Clinical Translational Science Institute. Dr. Long declares relationships with Novo Nordisk, Echosens Corporation, and Gilead Sciences. Dr. Yuan declares relationships with Genfit, Intercept, and Gilead Sciences. Dr. Younossi declares no relevant relationships.

‘Alarming’ global rise in NAFLD
The global prevalence of fatty liver disease not caused by alcohol is considerably higher than previously estimated and is continuing to increase at an alarming rate, report researchers from Canada.
Their analysis suggests nearly one-third of the global general adult population has nonalcoholic fatty liver disease (NAFLD), with men much more likely to have the disease than women.
“Greater awareness of NAFLD and the development of cost-effective risk stratification strategies are needed to address the growing burden NAFLD,” wrote Abdel-Aziz Shaheen, MBBCh, MSc, and colleagues with the University of Calgary (Alta.).
The study was published online in Lancet Gastroenterology and Hepatology.
NAFLD is the most common liver disease worldwide and a leading cause of liver-related illness and death. Yet, high-quality reports on the epidemiology of NAFLD at a global level are scarce and temporal trends of the NAFLD burden, including by gender, have not been described, until now.
Using MEDLINE, EMBASE, Scopus, and Web of Science, the Calgary team identified reports on NAFLD incidence and prevalence in study populations representative of the general adult population published between the date of database inception to May 25, 2021.
In total, 72 publications, with a sample population of more than 1 million adults from 17 countries, were included in the prevalence analysis, and 16 publications, with a sample population of nearly 382,000 individuals from five countries, were included in the incidence analysis.
By their estimates, the overall global prevalence of NAFLD is 32.4%, with prevalence increasing steadily and significantly over time, from 25.5% in or before 2005 to 37.8% in 2016 or later. The overall prevalence is significantly higher in men than in women (39.7% vs. 25.6%).
These figures contrast with recent meta-analyses and systematic reviews that put the global prevalence of NAFLD at between 25.2% and 29.8%. However, these studies had “considerable” limitations with “potentially biased inferences,” Dr. Shaheen and colleagues noted.
By region, their data put the prevalence of NAFLD at 31.6% in Asia, 32.6% in Europe, 47.8% in North America, and 56.8% in Africa.
Dr. Shaheen and colleagues estimate the overall incidence of NAFLD to be 46.9 cases per 1,000 person-years, with a higher incidence in men than women (70.8 vs. 29.6 cases per 1000 person-years), in line with the gender differences in prevalence.
They caution that there was “considerable” heterogeneity between studies in both NAFLD prevalence and incidence (I2 = 99.9%) and few “high-quality” studies.
Despite these limitations, Dr. Shaheen and colleagues said the rise in NAFLD prevalence “should drive enhanced awareness of NAFLD at the level of primary care physicians, public health specialists, and health policy makers to encourage the development of more effective preventive policies.”

The global prevalence of fatty liver disease not caused by alcohol is considerably higher than previously estimated and is continuing to increase at an alarming rate, report researchers from Canada.
Their analysis suggests nearly one-third of the global general adult population has nonalcoholic fatty liver disease (NAFLD), with men much more likely to have the disease than women.
“Greater awareness of NAFLD and the development of cost-effective risk stratification strategies are needed to address the growing burden NAFLD,” wrote Abdel-Aziz Shaheen, MBBCh, MSc, and colleagues with the University of Calgary (Alta.).
The study was published online in Lancet Gastroenterology and Hepatology.
NAFLD is the most common liver disease worldwide and a leading cause of liver-related illness and death. Yet, high-quality reports on the epidemiology of NAFLD at a global level are scarce and temporal trends of the NAFLD burden, including by gender, have not been described, until now.
Using MEDLINE, EMBASE, Scopus, and Web of Science, the Calgary team identified reports on NAFLD incidence and prevalence in study populations representative of the general adult population published between the date of database inception to May 25, 2021.
In total, 72 publications, with a sample population of more than 1 million adults from 17 countries, were included in the prevalence analysis, and 16 publications, with a sample population of nearly 382,000 individuals from five countries, were included in the incidence analysis.
By their estimates, the overall global prevalence of NAFLD is 32.4%, with prevalence increasing steadily and significantly over time, from 25.5% in or before 2005 to 37.8% in 2016 or later. The overall prevalence is significantly higher in men than in women (39.7% vs. 25.6%).
These figures contrast with recent meta-analyses and systematic reviews that put the global prevalence of NAFLD at between 25.2% and 29.8%. However, these studies had “considerable” limitations with “potentially biased inferences,” Dr. Shaheen and colleagues noted.

Hypertension heightens risk for severe COVID-19, even in the fully vaxxed
Adults with hypertension who were vaccinated for COVID-19 with at least one booster were more than twice as likely as vaccinated and boosted individuals without hypertension to be hospitalized for severe COVID-19, according to data from more than 900 individuals.
“We were surprised to learn that many people who were hospitalized with COVID-19 had hypertension and no other risk factors,” said Susan Cheng, MD, MPH, director of the Institute for Research on Healthy Aging in the department of cardiology at the Smidt Heart Institute, Los Angeles, and a senior author of the study. “This is concerning when you consider that almost half of American adults have high blood pressure.”
COVID-19 vaccines demonstrated ability to reduce death and some of the most severe side effects from the infection in the early stages of the pandemic. Although the Omicron surge prompted recommendations for a third mRNA vaccine dose, “a proportion of individuals who received three mRNA vaccine doses still required hospitalization for COVID-19 during the Omicron surge,” and the characteristics associated with severe illness in vaccinated and boosted patients have not been explored, Joseph Ebinger, MD, of Cedars-Sinai Medical Center, Los Angeles, and colleagues wrote.
Previous research has shown an association between high blood pressure an increased risk for developing severe COVID-19 compared to several other chronic health conditions, including kidney disease, type 2 diabetes, chronic obstructive pulmonary disease, and heart failure, the researchers noted.
In a study published in Hypertension, the researchers identified 912 adults who received at least three doses of mRNA COVID-19 vaccine and were later diagnosed with COVID-19 during the surge in infections from the Omicron variant between December 2021 and April 2022.
A total of 145 of the individuals were hospitalized (16%); of these, 125 (86%) had hypertension.
Patients with hypertension were the most likely to be hospitalized, with an odds ratio of 2.9. In addition to high blood pressure, factors including older age (OR, 1.3), chronic kidney disease (OR, 2.2), prior myocardial infarction or heart failure (OR, 2.2), and longer time since the last vaccination and COVID-19 infection were associated with increased risk of hospitalization in a multivariate analysis.
However, the increased risk of severe illness and hospitalization associated with high blood pressure persisted, with an OR of 2.6, in the absence of comorbid conditions such as type 2 diabetes, kidney disease, and heart failure, the researchers emphasized.
“Although the mechanism for hypertension-associated COVID-19 risk remains unclear, prior studies have identified delayed SARS-CoV-2 viral clearance and prolonged inflammatory response among hypertensive patients, which may contribute to greater disease severity,” they wrote.
The findings were limited by several factors, including the use of data from a single center and lack of information on which Omicron variants and subvariants were behind the infections, the researchers noted.
However, the results highlight the need for more research on how to reduce the risks of severe COVID-19 in vulnerable populations, and on the mechanism for a potential connection between high blood pressure and severe COVID-19, they said.
Given the high prevalence of hypertension worldwide, increased understanding of the hypertension-specific risks and identification of individual and population-level risk reduction strategies will be important to the transition of COVID-19 from pandemic to endemic, they concluded.
Omicron changes the game
“When the pandemic initially started, many conditions were seen to increase risk for more severe COVID illness, and hypertension was one of those factors – and then things changed,” lead author Dr. Ebinger said in an interview. “First, vaccines arrived on the scene and substantially reduced risk of severe COVID for everyone who received them. Second, Omicron arrived and, while more transmissible, this variant has been less likely to cause severe COVID. On the one hand, we have vaccines and boosters that we want to think of as ‘the great equalizer’ when it comes to preexisting conditions. On the other hand, we have a dominant set of SARS-CoV-2 subvariants that seem less virulent in most people.
“Taken together, we have been hoping and even assuming that we have been doing pretty well with minimizing risks. Unfortunately, our study results indicate this is not exactly the case,” he said.
“Although vaccines and boosters appear to have equalized or minimized the risks of severe COVID for some people, this has not happened for others – even in the setting of the milder Omicron variant. Of individuals who were fully vaccinated and boosted, having hypertension increased the odds of needing to be hospitalized after getting infected with Omicron by 2.6-fold, even when accounting for or in the absence of having any major chronic disease that might otherwise predispose to more severe COVID-19 illness,” Dr. Ebinger added.
“So, while the originally seen risks of having obesity or diabetes seem to have been minimized during this current era of pandemic, the risk of having hypertension has persisted. We found this both surprising and concerning, because hypertension is very common and present in over half of people over age 50.”
Surprisingly, “we found that a fair number of people, even after being fully vaccinated plus a having gotten a booster, will not only catch Omicron but get sick enough to need hospital care,” Dr. Ebinger emphasized. “Moreover, it is not just older adults with major comorbid conditions who are vulnerable. Our data show that this can happen to an adult of any age and especially if a person has only hypertension and otherwise no major chronic disease.”
The first takeaway message for clinicians at this time is to raise awareness, Dr. Ebinger stressed in the interview. “We need to raise understanding around the fact that receiving three doses of vaccine may not prevent severe COVID-19 illness in everyone, even when the circulating viral variant is presumed to be causing only mild disease in most people. Moreover, the people who are most at risk are not whom we might think they are. They are not the sickest of the sick. They include people who might not have major conditions such as heart disease or kidney disease, but they do have hypertension.”
Second, “we need more research to understand out why there is this link between hypertension and excess risk for the more severe forms of COVID-19, despite it arising from a supposedly milder variant,” said Dr. Ebinger.
“Third, we need to determine how to reduce these risks, whether through more tailored vaccine regimens or novel therapeutics or a combination approach,” he said.
Looking ahead, “the biological mechanism underpinning the association between hypertension and severe COVID-19 remains underexplored. Future work should focus on understanding the factors linking hypertension to severe COVID-19, as this may elucidate both information on how SARS-CoV-2 effects the body and potential targets for intervention,” Dr. Ebinger added.
The study was supported in part by Cedars-Sinai Medical Center, the Erika J. Glazer Family Foundation and the National Institutes of Health. The researchers had no financial conflicts to disclose.

Rosuvastatin again linked with risks to kidneys
Rosuvastatin for cholesterol lowering was associated with slightly greater risks for kidney harm than atorvastatin, risks that were greater at higher-dose levels, in a large retrospective cohort study.
The most potent statin on the market, rosuvastatin has been linked with excess risk for kidney damage compared with atorvastatin in case reports and small trials, but there has been little surveillance of the issue following its approval in 2003.
The current analysis “is one of the first and largest real-world studies” examining rosuvastatin versus atorvastatin for risk for hematuria, proteinuria, and kidney failure with replacement therapy – dialysis or transplantation – across a range of estimated glomerular filtration rates (eGFR) in a heterogeneous population, the researchers write.
“Our findings suggest the need for greater care in prescribing and monitoring of rosuvastatin, particularly in patients who are receiving high doses” or have severe chronic kidney disease (CKD), they concluded in their report published online in the Journal of the American Society of Nephrology.
The analysis included close to 1 million patients in the United States who were newly prescribed rosuvastatin or atorvastatin from 2011 through 2019; they were followed a median of 3.1 years. Among the findings:
- Users of rosuvastatin had an 8% higher risk for hematuria, a 17% higher risk for proteinuria, and a 15% higher risk for kidney failure with replacement therapy, compared with those on atorvastatin
- The two groups avoided MI and stroke to similar extents
- About 44% of patients with severe CKD G4+ (eGFR < 30 mL/min per 1.73 m2) were prescribed a higher rosuvastatin dosage than the maximum 10 mg/day recommended for such patients by the Food and Drug Administration.
From this study, “we do not know why the adherence of FDA dosing recommendation for rosuvastatin in patients with severe CKD is low,” lead author Jung-Im Shin, MD, PhD, said in an interview.
“It is likely that not many clinicians are aware of rosuvastatin’s dosing recommendations [in severe CKD], or potential risks of hematuria or proteinuria,” speculated Dr. Shin, assistant professor at Johns Hopkins University, Baltimore.
“High-dose rosuvastatin [and its cardiovascular benefits] may not merit the risk, even if small, particularly in low eGFR,” she said. “Our study provides the opportunity to increase awareness of this clinical issue.”
“Future studies are warranted to shed light on the discrepancy between real-world practice and FDA dosing recommendations for high-dose rosuvastatin,” the researchers noted.
‘Greater awareness and education are key’
Invited to comment, Swapnil Hiremath, MD, a nephrologist at the Ottawa Hospital Research Institute, noted that the higher risk for nephrotoxicity with high-dose rosuvastatin versus high-dose atorvastatin was shown in the PLANET 1 trial published in 2015 and in, for example, a case report published in 2016 – which the researchers also mention.
“I was personally surprised” at the high proportion of patients with severe CKD who received higher than recommended doses of rosuvastatin, said Dr. Hiremath, who is also an associate professor at the University of Ottawa and a Freely Filtered podcaster, and not associated with the current study.
“We do see this occasionally,” he continued, “but either because someone is targeting LDL [cholesterol] and hasn’t noted the GFR, or possibly the patient was started on a high dose a long time ago and the kidney function has declined, and no one has noted the high dose.”
“Greater awareness and education are key,” observed Dr. Hiremath. “My personal bias is to have renal pharmacists involved in multidisciplinary clinics when GFR [is] less than 30 or so,” he said. “There are so many other tricky medicine/interaction issues” in patients with kidney disease.
Nevertheless, “I would be careful in drawing too many conclusions from an observational study,” Dr. Hiremath added. “There’s always the threat of residual confounding and selection bias,” which the researchers acknowledge, “and especially competing risks.”
For example, “if there is less cardiovascular death with rosuvastatin, then more people will remain alive to develop kidney failure.”
Dosing in practice unclear
Atorvastatin at 40-mg and 80-mg dosages and rosuvastatin at 20 mg and 40 mg are the only two statins considered high-intensity, the researchers noted.
Development of an 80-mg dosage for rosuvastatin was dropped because of hematuria and proteinuria safety signals highlighted at the time of rosuvastatin’s FDA approval.
However, there has been little postmarketing surveillance to assess real-world risk from high-intensity rosuvastatin, and it remains unclear whether and to what extent clinical practice adheres to the starting dosage recommended by the FDA in severe CKD, 5 mg/day with a maximum of 10 mg/day, the report noted.
The researchers analyzed deidentified electronic health record data from 40 health care organizations in the United States from the OptumLabs Data Warehouse database. They entered 152,101 new rosuvastatin users and 795,799 new atorvastatin users, and excluded patients with a history of rhabdomyolysis.
Patients in the two groups were similar with respect to CKD prevalence, cardiovascular risk factors, and demographics. Their age averaged 60 years, 48% were women, and 82% were White.
Hematuria was defined as dipstick hematuria > + or the presence of more than 3 red blood cells per high-power field in urine microscopy, at least twice. Proteinuria was defined as dipstick proteinuria > ++ or urine albumin-to-creatinine ratio greater than 300 mg/g at least twice.
Overall, 2.9% of patients had hematuria (3.4% of the rosuvastatin group and 2.8% of those taking atorvastatin) and 1% of patients had proteinuria (1.2% and 0.9%, respectively).
After balancing baseline characteristics in both groups using inverse probability of treatment weighting, rosuvastatin treatment, compared with atorvastatin, was associated with significantly greater risks for hematuria (hazard ratio, 1.08), proteinuria (HR, 1.17), and kidney failure requiring replacement therapy (HR, 1.15).
Patients with eGFR less than 30 mL/min per 1.73 m2 had an approximately twofold higher risk for hematuria and ninefold higher risk for proteinuria during the follow-up compared with patients with eGFR of at least 60 mL/min per 1.73 m2.
Patients with eGFR less than 30 mL/min per 1.73 m2 were commonly prescribed high-dose rosuvastatin (29.9% received the 20-mg dose and 14% the 40-mg dose), contrary to the labeling recommendation.
Dr. Shin reported receiving research Funding from the National Institutes of Health and Merck; disclosures for the other authors are in the report. Dr. Hiremath reported having no relevant financial relationships.

- Users of rosuvastatin had an 8% higher risk for hematuria, a 17% higher risk for proteinuria, and a 15% higher risk for kidney failure with replacement therapy, compared with those on atorvastatin
- The two groups avoided MI and stroke to similar extents
- About 44% of patients with severe CKD G4+ (eGFR < 30 mL/min per 1.73 m2) were prescribed a higher rosuvastatin dosage than the maximum 10 mg/day recommended for such patients by the Food and Drug Administration.
From this study, “we do not know why the adherence of FDA dosing recommendation for rosuvastatin in patients with severe CKD is low,” lead author Jung-Im Shin, MD, PhD, said in an interview.
“It is likely that not many clinicians are aware of rosuvastatin’s dosing recommendations [in severe CKD], or potential risks of hematuria or proteinuria,” speculated Dr. Shin, assistant professor at Johns Hopkins University, Baltimore.
“High-dose rosuvastatin [and its cardiovascular benefits] may not merit the risk, even if small, particularly in low eGFR,” she said. “Our study provides the opportunity to increase awareness of this clinical issue.”
“Future studies are warranted to shed light on the discrepancy between real-world practice and FDA dosing recommendations for high-dose rosuvastatin,” the researchers noted.
‘Greater awareness and education are key’
Invited to comment, Swapnil Hiremath, MD, a nephrologist at the Ottawa Hospital Research Institute, noted that the higher risk for nephrotoxicity with high-dose rosuvastatin versus high-dose atorvastatin was shown in the PLANET 1 trial published in 2015 and in, for example, a case report published in 2016 – which the researchers also mention.
“I was personally surprised” at the high proportion of patients with severe CKD who received higher than recommended doses of rosuvastatin, said Dr. Hiremath, who is also an associate professor at the University of Ottawa and a Freely Filtered podcaster, and not associated with the current study.
“We do see this occasionally,” he continued, “but either because someone is targeting LDL [cholesterol] and hasn’t noted the GFR, or possibly the patient was started on a high dose a long time ago and the kidney function has declined, and no one has noted the high dose.”
“Greater awareness and education are key,” observed Dr. Hiremath. “My personal bias is to have renal pharmacists involved in multidisciplinary clinics when GFR [is] less than 30 or so,” he said. “There are so many other tricky medicine/interaction issues” in patients with kidney disease.
Nevertheless, “I would be careful in drawing too many conclusions from an observational study,” Dr. Hiremath added. “There’s always the threat of residual confounding and selection bias,” which the researchers acknowledge, “and especially competing risks.”
For example, “if there is less cardiovascular death with rosuvastatin, then more people will remain alive to develop kidney failure.”
Dosing in practice unclear
Atorvastatin at 40-mg and 80-mg dosages and rosuvastatin at 20 mg and 40 mg are the only two statins considered high-intensity, the researchers noted.
Development of an 80-mg dosage for rosuvastatin was dropped because of hematuria and proteinuria safety signals highlighted at the time of rosuvastatin’s FDA approval.
However, there has been little postmarketing surveillance to assess real-world risk from high-intensity rosuvastatin, and it remains unclear whether and to what extent clinical practice adheres to the starting dosage recommended by the FDA in severe CKD, 5 mg/day with a maximum of 10 mg/day, the report noted.
The researchers analyzed deidentified electronic health record data from 40 health care organizations in the United States from the OptumLabs Data Warehouse database. They entered 152,101 new rosuvastatin users and 795,799 new atorvastatin users, and excluded patients with a history of rhabdomyolysis.
Patients in the two groups were similar with respect to CKD prevalence, cardiovascular risk factors, and demographics. Their age averaged 60 years, 48% were women, and 82% were White.
Hematuria was defined as dipstick hematuria > + or the presence of more than 3 red blood cells per high-power field in urine microscopy, at least twice. Proteinuria was defined as dipstick proteinuria > ++ or urine albumin-to-creatinine ratio greater than 300 mg/g at least twice.
Overall, 2.9% of patients had hematuria (3.4% of the rosuvastatin group and 2.8% of those taking atorvastatin) and 1% of patients had proteinuria (1.2% and 0.9%, respectively).
After balancing baseline characteristics in both groups using inverse probability of treatment weighting, rosuvastatin treatment, compared with atorvastatin, was associated with significantly greater risks for hematuria (hazard ratio, 1.08), proteinuria (HR, 1.17), and kidney failure requiring replacement therapy (HR, 1.15).
Patients with eGFR less than 30 mL/min per 1.73 m2 had an approximately twofold higher risk for hematuria and ninefold higher risk for proteinuria during the follow-up compared with patients with eGFR of at least 60 mL/min per 1.73 m2.
Patients with eGFR less than 30 mL/min per 1.73 m2 were commonly prescribed high-dose rosuvastatin (29.9% received the 20-mg dose and 14% the 40-mg dose), contrary to the labeling recommendation.
Dr. Shin reported receiving research Funding from the National Institutes of Health and Merck; disclosures for the other authors are in the report. Dr. Hiremath reported having no relevant financial relationships.

Rosuvastatin for cholesterol lowering was associated with slightly greater risks for kidney harm than atorvastatin, risks that were greater at higher-dose levels, in a large retrospective cohort study.
The most potent statin on the market, rosuvastatin has been linked with excess risk for kidney damage compared with atorvastatin in case reports and small trials, but there has been little surveillance of the issue following its approval in 2003.
The current analysis “is one of the first and largest real-world studies” examining rosuvastatin versus atorvastatin for risk for hematuria, proteinuria, and kidney failure with replacement therapy – dialysis or transplantation – across a range of estimated glomerular filtration rates (eGFR) in a heterogeneous population, the researchers write.

FDA clears endoscopic devices for sleeve gastroplasty, bariatric revision
The Food and Drug Administration has cleared for marketing the first devices indicated for endoscopic sleeve gastroplasty (ESG) and endoscopic bariatric revision, according to the manufacturer.
The Apollo ESG, Apollo ESG Sx, Apollo Revise, and Apollo Revise Sx systems made by Apollo Endosurgery were reviewed through the de novo premarket review pathway, a regulatory pathway for low- to moderate-risk devices of a new type.
“The Apollo ESG and Apollo Revise systems offer a compelling mix of effectiveness, safety, durability, and convenience for treatment of patients with obesity,” Chas McKhann, president and CEO of the company, said in a news release.
“The authorization of these new endoscopic systems represents a major step forward in addressing the global obesity epidemic,” Mr. McKhann added.
The Apollo ESG and Apollo ESG Sx systems are intended for use by trained gastroenterologists or surgeons to facilitate weight loss in adults with obesity who have failed to lose weight or maintain weight loss through more conservative measures, the company says.
The Apollo Revise and Apollo Revise Sx systems allow gastroenterologists or surgeons to perform transoral outlet reduction (TORe) as a revision to a previous bariatric procedure.
Studies have shown that 10 years after bariatric surgery, patients have regained an average of 20%-30% of weight they initially lost. Bariatric revision procedures are the fastest growing segment of the bariatric surgery market.
TORe is an endoscopic procedure performed to revise a previous gastric bypass and like ESG, can be performed as a same-day procedure without incisions or scars.

‘I shall harm’
I was quite sure I had multiple sclerosis when I was a medical student. I first noticed symptoms during my neurology rotation. All the signs were there: Fatigue that was getting worse in the North Carolina heat (Uhthoff sign!). A tingle running down my neck (Lhermitte sign!). Blurry vision late at night while studying pathways in Lange Neurology. “Didn’t cousin Amy have MS?” I asked my Mom. I started researching which medical specialties didn’t require dexterity. My left eyelid began twitching and didn’t stop until I rotated to ob.gyn.
Fortunately, it was not multiple sclerosis I had, but rather nosophobia, also known as Medical Student’s Disease. The combination of intense study of symptoms, spotty knowledge of diagnoses, and grade anxiety makes nosophobia common in med students. Despite its name, it doesn’t afflict only doctors. Patients often come to us convinced they have a disease but without reason. So unshakable is their belief that multiple visits are often required to disabuse them of their self-diagnosis. I sometimes have to remind myself to appear concerned even when a “melanoma” is a freckle so small I can barely see it with a dermatoscope. Or a “genital wart” is a hair follicle that looks exactly like the hundreds on the patient’s scrotum. Tougher though, are the treatment-avoiders: patients whose imagined side effects lead them to stop or refuse treatment.
I recently saw a middle-aged man with erythroderma so severe he looked like a ghillie suit of scale. He had a lifelong history of atopic dermatitis and a 2-year history of avoiding treatments. At some point, he tried all the usual remedies: cyclosporine, methotrexate, azathioprine, light therapy, boxes of topicals. The last treatment had been dupilumab, which he tried for a few weeks. “Why did you stop that one?” I asked. The injections were making him go blind, he explained. “Not blurry? Blind?” I asked. Yes, he could not see at all after each injection. Perhaps he might have dry eyes or keratitis? Sure. But blindness? It seemed an unreasonable concern. Further discussion revealed that intolerance to medication side effects was why he had stopped all his other treatments.
Nocebo, from the Latin “I shall harm,” is the dark counterpart to the placebo. Patients experience imagined, or even real, adverse effects because they believe the treatment is causing them harm. This is true even though that treatment might not be having any unwanted physiologic effect. Statins are a good example. Studies have shown that most patient-reported side effects of statins are in fact nocebo effects rather than a result of pharmacologic causes.
Yet, many patients on statins report muscle pain or other concerns as unbearable. As a consequence, some patients who might have benefited from statins might be missing out on the protective gains. as compared with bad outcomes that occurred from not taking action. It’s frustrating when there’s a standard of care treatment, but our patient can’t get past their fear of harm to try it.
Despite my recommendations, my eczema patient insisted on continuing his nontreatment rather than take any risks with treatments for now. There are ways I might help, but I expect it will require additional visits to build trust. Today, the best I can do is to understand and respect him. At least he doesn’t think he has a genital wart – I’m not sure how I’d treat it if he did.

Statins linked to lower diabetes risk after acute pancreatitis
Use of cholesterol-lowering statins was linked to a lower risk of developing a subtype of diabetes that occurs after acute pancreatitis, according to a new report.
The benefits of statins depended on the consistency of usage, with regular users having a lower risk of developing postpancreatitis diabetes than irregular users. The results were similar with low, moderate, and high statin doses, as well as in cases of both mild and severe acute pancreatitis.
“About 15% of patients with acute pancreatitis will develop diabetes mellitus in the next 5 years, and although we can monitor for it, we can’t do anything to prevent it,” Nikhil Thiruvengadam, MD, the lead study author and a gastroenterologist at Loma Linda (Calif.) University, told this news organization.
“This could push you as a clinician to prescribe [a statin if you have a reason to] because it could provide two benefits instead of just one,” he said.
The study was published online in Clinical Gastroenterology and Hepatology.
Steady use mattered, not dose
Patients with acute pancreatitis face at least a twofold increased risk of developing postpancreatitis diabetes, the study authors write. Although previous studies have shown that statins can lower the incidence and severity of acute pancreatitis, they haven’t been studied for the prevention of postpancreatitis diabetes.
In a collaborative study with several other universities, Dr. Thiruvengadam and colleagues examined commercial insurance claims from the Optum Clinformatics database to assess the impact of statins on 118,479 patients without preexisting diabetes admitted for a first episode of acute pancreatitis between 2008 and 2020.
They compared patients who consistently used statins with irregular users and nonusers. Regular statin usage was defined as patients who had statin prescriptions filled for at least 80% of the year prior to their acute pancreatitis diagnosis. The analysis included 9,048 patients (7.6%) who used statins regularly, 27,272 (23%) who used statins irregularly, and 82,159 (69.3%) nonusers.
With a median follow-up of 3.5 years, the 5-year cumulative incidence of postpancreatitis diabetes was 7.5% among regular statin users and 12.7% among nonusers. Regular statin users had a 42% lower risk of developing postpancreatitis diabetes, compared with nonusers. Irregular statin users had a 15% lower risk of postpancreatitis diabetes.
In addition, the 5-year cumulative incidence of insulin-dependent postpancreatitis diabetes was 2.4% among regular statin users and 6.6% among nonusers. Regular statin users had a 52% lower risk of developing insulin-dependent diabetes as compared with nonusers.
Daily dosage didn’t demonstrate a linear dose-response relationship. That means high-dose statins may not be more effective in preventing diabetes as compared with lower doses, the study authors write.
Statin usage was effective across additional analyses, including sex, etiologies of pancreatitis, and in both mild and severe acute pancreatitis. According to the study authors, this suggests that a broad population of these patients may benefit from statins.
“We were pleasantly surprised by the variety of findings,” Dr. Thiruvengadam said. “We’re seeing strong signals, especially with consistency of usage.”
Ongoing studies
The results may seem paradoxical, the study authors write, given an epidemiologic association with a slight increase in new-onset diabetes with statin initiation. But, as other researchers have reported, postpancreatitis diabetes and type 2 diabetes have different clinical features and underlying pathophysiology. For example, patients with postpancreatitis diabetes have much higher rates of requiring insulin, hospitalization, and all-cause mortality, the study authors write.
In fact, postpancreatitis diabetes is thought to be driven by chronic low-grade inflammation attributable to interleukin-6 and tumor necrosis factor–alpha. Statins have been shown to reduce tumor necrosis factor–alpha secretion and the production of C-reactive protein in response to circulating interleukin-6 in hepatocytes, they write.
The results should inform long-term prospective studies of acute pancreatitis, the study authors write, as well as randomized controlled trials of statins.
In the meantime, gastroenterologists and primary care physicians who see outpatients after hospitalization for acute pancreatitis may consider using statins, particularly in those who may have another possible indication for statin therapy, such as mild hyperlipidemia.
“There appears to be a low-dose benefit, which is another reason why providers may consider using statins, though it’s not for everyone with pancreatitis,” Dr. Thiruvengadam said. “This could be an exploratory pathway and suggested for use in the right setting.”
The Type 1 Diabetes in Acute Pancreatitis Consortium, sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases, is conducting an observational cohort study at more than a dozen locations across the country to investigate the incidence, etiology, and pathophysiology of diabetes after acute pancreatitis.
“Diabetes is surprisingly common after even a single attack of acute pancreatitis,” Chris Forsmark, MD, professor of medicine and chief of the division of gastroenterology, hepatology, and nutrition at the University of Florida, Gainesville, told this news organization.
Dr. Forsmark, who wasn’t involved with this study, is a member of T1DAPC and one of the principal investigators in Florida.
“The reduction of risk by 42% is quite substantial,” he said. “Like all such studies, there is risk of bias and confounding in determining the actual risk. Nonetheless, the results provide a strong reason for confirmation in other datasets and for further study.”
The study didn’t report funding support. Dr. Thiruvengadam and Dr. Forsmark report no relevant financial relationships.

“This could push you as a clinician to prescribe [a statin if you have a reason to] because it could provide two benefits instead of just one,” he said.
The study was published online in Clinical Gastroenterology and Hepatology.
Steady use mattered, not dose
Patients with acute pancreatitis face at least a twofold increased risk of developing postpancreatitis diabetes, the study authors write. Although previous studies have shown that statins can lower the incidence and severity of acute pancreatitis, they haven’t been studied for the prevention of postpancreatitis diabetes.
In a collaborative study with several other universities, Dr. Thiruvengadam and colleagues examined commercial insurance claims from the Optum Clinformatics database to assess the impact of statins on 118,479 patients without preexisting diabetes admitted for a first episode of acute pancreatitis between 2008 and 2020.
They compared patients who consistently used statins with irregular users and nonusers. Regular statin usage was defined as patients who had statin prescriptions filled for at least 80% of the year prior to their acute pancreatitis diagnosis. The analysis included 9,048 patients (7.6%) who used statins regularly, 27,272 (23%) who used statins irregularly, and 82,159 (69.3%) nonusers.
With a median follow-up of 3.5 years, the 5-year cumulative incidence of postpancreatitis diabetes was 7.5% among regular statin users and 12.7% among nonusers. Regular statin users had a 42% lower risk of developing postpancreatitis diabetes, compared with nonusers. Irregular statin users had a 15% lower risk of postpancreatitis diabetes.
In addition, the 5-year cumulative incidence of insulin-dependent postpancreatitis diabetes was 2.4% among regular statin users and 6.6% among nonusers. Regular statin users had a 52% lower risk of developing insulin-dependent diabetes as compared with nonusers.
Daily dosage didn’t demonstrate a linear dose-response relationship. That means high-dose statins may not be more effective in preventing diabetes as compared with lower doses, the study authors write.
Statin usage was effective across additional analyses, including sex, etiologies of pancreatitis, and in both mild and severe acute pancreatitis. According to the study authors, this suggests that a broad population of these patients may benefit from statins.
“We were pleasantly surprised by the variety of findings,” Dr. Thiruvengadam said. “We’re seeing strong signals, especially with consistency of usage.”
Ongoing studies
The results may seem paradoxical, the study authors write, given an epidemiologic association with a slight increase in new-onset diabetes with statin initiation. But, as other researchers have reported, postpancreatitis diabetes and type 2 diabetes have different clinical features and underlying pathophysiology. For example, patients with postpancreatitis diabetes have much higher rates of requiring insulin, hospitalization, and all-cause mortality, the study authors write.
In fact, postpancreatitis diabetes is thought to be driven by chronic low-grade inflammation attributable to interleukin-6 and tumor necrosis factor–alpha. Statins have been shown to reduce tumor necrosis factor–alpha secretion and the production of C-reactive protein in response to circulating interleukin-6 in hepatocytes, they write.
The results should inform long-term prospective studies of acute pancreatitis, the study authors write, as well as randomized controlled trials of statins.
In the meantime, gastroenterologists and primary care physicians who see outpatients after hospitalization for acute pancreatitis may consider using statins, particularly in those who may have another possible indication for statin therapy, such as mild hyperlipidemia.
“There appears to be a low-dose benefit, which is another reason why providers may consider using statins, though it’s not for everyone with pancreatitis,” Dr. Thiruvengadam said. “This could be an exploratory pathway and suggested for use in the right setting.”
The Type 1 Diabetes in Acute Pancreatitis Consortium, sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases, is conducting an observational cohort study at more than a dozen locations across the country to investigate the incidence, etiology, and pathophysiology of diabetes after acute pancreatitis.
“Diabetes is surprisingly common after even a single attack of acute pancreatitis,” Chris Forsmark, MD, professor of medicine and chief of the division of gastroenterology, hepatology, and nutrition at the University of Florida, Gainesville, told this news organization.
Dr. Forsmark, who wasn’t involved with this study, is a member of T1DAPC and one of the principal investigators in Florida.
“The reduction of risk by 42% is quite substantial,” he said. “Like all such studies, there is risk of bias and confounding in determining the actual risk. Nonetheless, the results provide a strong reason for confirmation in other datasets and for further study.”
The study didn’t report funding support. Dr. Thiruvengadam and Dr. Forsmark report no relevant financial relationships.

Use of cholesterol-lowering statins was linked to a lower risk of developing a subtype of diabetes that occurs after acute pancreatitis, according to a new report.
The benefits of statins depended on the consistency of usage, with regular users having a lower risk of developing postpancreatitis diabetes than irregular users. The results were similar with low, moderate, and high statin doses, as well as in cases of both mild and severe acute pancreatitis.

FROM CLINICAL GASTROENTEROLOGY AND HEPATOLOGY
An avocado a day doesn’t shrink belly fat, but helps with cholesterol
according to the findings of a new study.
But it did improve diet quality and led to modest lowering of total cholesterol.
More than 1,000 adults with overweight or obesity and a large waist – at least 35 inches in women and 40 inches in men – took part in this U.S. study, called the Habitual Diet and Avocado Trial (HAT).
The people in the study were divided into two groups: usual diet plus one large avocado every day and usual diet with two avocados at most per month (control group).
Those in the avocado-a-day group were given a regular supply of fresh avocados along with written instructions for how to ripen and prepare them.
They had MRI scans to measure belly fat and fat around other organs at the beginning of the study and after 6 months.
After 6 months, the people who ate an avocado a day did not have less fat around their middles – the main trial outcome – compared with people in the control group.
But at 6 months, those in the avocado-a-day group had:
- No weight gain. People’s weight remained stable in both groups.
- Improved diet quality by 8 points on a 100-point scale
- A 2.9-mg/dL decrease in total cholesterol
- A 2.5-mg/dL decrease in LDL cholesterol
The study was done by researchers at Penn State University; Tufts University; Loma Linda University; and the University of California, Los Angeles, with coordinating support from Wake Forest University.
It was published in the Journal of the American Heart Association.
“While the avocados did not affect belly fat or weight gain, the study still provides evidence that avocados can be a beneficial addition to a well-balanced diet,” Penny M. Kris-Etherton, PhD, one of the researchers and a professor of nutritional sciences at Penn State University, University Park, said in a news release.
“Incorporating an avocado per day in this study did not cause weight gain and also caused a slight decrease in LDL cholesterol, which are all important findings for better health,” she said.
Similarly, study researcher Joan Sabaté, MD, a professor at Loma Linda (Calif.) University, said: “While one avocado a day did not lead to clinically significant improvements in abdominal fat and other cardiometabolic risk factors, consuming one avocado a day did not result in body weight gain.”
“This is positive,” he said, “because eating extra calories from avocados doesn’t impact body weight or abdominal fat, and it slightly decreases total and LDL cholesterol.”
Kristina S. Petersen, PhD, another of the researchers and an assistant professor of nutritional sciences at Texas Tech University, Lubbock, pointed out that people are generally poor at adhering to the Dietary Guidelines for Americans.
This study suggests that an avocado a day can improve diet quality, she noted, which “ is important because we know a higher diet quality is associated with lower risk of several diseases, including heart disease, type 2 diabetes, and some cancers.”
But the researchers also stressed that it is important to consider the diet as a whole.
“Consistent with prior observations, a change in dietary patterns rather than a single food or nutrient may be necessary to achieve clinically significant improvements” in belly fat and other risk factors for heart attack, stroke, and diabetes, they wrote.
HAT was funded by the Hass Avocado Board, which also supplied the avocados.

PCOS in mothers tied to health problems in children
Children whose mothers have polycystic ovary syndrome (PCOS) have increased rates of hospitalization for various conditions, including asthma, pneumonia, and ear infection, a study of more than 1 million children shows.
The associations were not particularly strong, according to the researchers. But they raise questions about the reasons for the increased risk and whether interventions such as diet, exercise, or medications could lead to healthier outcomes for children whose mothers have PCOS.
“The findings suggest that maternal PCOS may have a negative impact on offspring development, enough to lead to a measurable increase in the risk of childhood hospitalization,” study coauthor Nathalie Auger, MD, associate professor of epidemiology at University of Montreal, and colleagues reported in Human Reproduction.
“They are minor differences, just enough that we can statistically identify them. They’re not something where everyone should be worrying at this point,” Dr. Auger told this news organization.
Still, some of the hospitalizations, such as those related to infection or allergy, could be prevented with earlier ambulatory care, so some degree of greater awareness among parents and clinicians may be warranted, she said.
Thirteen years of follow-up
PCOS – a reproductive disorder characterized by irregular periods, increased male hormones, and metabolic complications – affects some 10% of women. People with the condition are at increased risk for obesity, type 2 diabetes, and cardiovascular disease.
Although prior research has shown that maternal PCOS may be associated with higher body mass index and attention deficit disorder in children, data on long-term childhood health outcomes have been limited, Dr. Auger’s group noted.
To examine illness in children exposed to maternal PCOS, the investigators analyzed hospitalization rates for nearly 1.04 million children in Quebec between 2006 and 2020; 7,160 of the children had mothers with PCOS.
In all, 275,354 children were hospitalized during 13 years of follow-up, including 2,314 whose mothers had PCOS.
Children exposed to PCOS were hospitalized at a rate of 68.9 per 1,000 person-years – roughly 50% more often than the rate of 45.3 per 1,000 person-years for children not exposed to maternal PCOS.
In an analysis that adjusted for maternal characteristics, childhood hospitalization for any reason was 1.32 times more likely for children exposed to maternal PCOS.
Hospitalizations linked to infectious diseases – such as for bronchitis, bronchiolitis, pneumonia, nephritis, otitis media, or meningitis – were 1.31 times more likely among children exposed to PCOS. Allergy-related hospitalizations, such as for allergic asthma and anaphylaxis, were 1.47 times more likely, according to the researchers.
Metabolic hospitalizations were 1.59 times more likely. For gastrointestinal hospitalizations, the hazard ratio was 1.72. For central nervous system hospitalizations, it was 1.74.
The associations were stronger in earlier childhood, and results were similar for boys and girls, the investigators reported.
Hospitalizations for cardiovascular disease, musculoskeletal conditions, or malignancy were not increased.
‘Surprising’ links
“The findings are surprising in that some of the conditions that they showed increased risk for, like asthma and some infections, are not conditions that we think of as being typically associated with PCOS,” said Andrea E. Dunaif, MD, chief of the Hilda and J. Lester Gabrilove Division of Endocrinology, Diabetes, and Bone Disease at Mount Sinai Health System, New York, who was not part of the study team.
Earlier studies of offspring of women with PCOS have suggested that children may be at increased risk for insulin resistance and obesity.
Differences in genetics, intrauterine environments, patterns of health care use by women with PCOS, and behavioral factors, such as diet and how children are raised, are variables that could have contributed to the different hospitalization rates among children exposed to maternal PCOS, Dr. Auger said.
“Everything is interconnected,” she said.
The study was supported by a grant from the Canadian Institutes of Health Research. Dr. Auger has received a career award from Fonds de Recherche du Québec-Santé. Dr. Dunaif has consulted for Novo Nordisk and Fractyl Laboratories (now Fractyl Health).
