Microplastics permeate human placentas
Researchers in Italy have identified microplastic (MP) fragments in four human placentas that were donated for study after delivery.
“The presence of MPs in the placenta tissue requires the reconsideration of the immunological mechanism of self-tolerance,” wrote Antonio Ragusa, MD, of San Giovanni Calibita Fatebenefratelli Hospital, Rome, and colleagues. “Placenta represents the interface between the fetus and the environment.”
In a pilot observational study published in Environment International, the researchers used Raman microspectroscopy to analyze placentas from six women with physiological pregnancies for the presence of MPs. MPs were defined as particles smaller than 5 mm resulting from the degradation of plastic in the environment, such as plastic objects, coatings, adhesives, paints, and personal care products. Data from previous studies have shown that MPs can move into living organisms, but this study is the first to identify MPs in human placentas, the researchers said.
Polypropylene and pigments identified
A total of 12 microplastic fragments were identified in tissue from the placentas of four women; 5 in the fetal side, 4 in the maternal side, and 3 in the chorioamniotic membranes, which suggests that MPs can reach all levels of placental tissue, the researchers said. Most of the MPs were approximately 10 mcm in size, but two were roughly 5 mcm.
All 12 of the MPs were pigmented; of these, 3 were identified as stained polypropylene and the other 9 contained pigments used in a variety of items including coatings, paints, adhesives, plasters, finger paints, polymers and cosmetics, and personal care products. The researchers used a software program to analyze the pigments and matched them with information from the European Chemical Agency for identification of the commercial name, chemical formula, International Union of Pure and Applied Chemistry name, and Color Index Constitution Number.
The mechanism by which MPs may enter the bloodstream and access the placenta remains unclear, the researchers said. “The most probable transport route for MPs is a mechanism of particle uptake and translocation, already described for the internalization from the gastrointestinal tract. Once MPs have reached the maternal surface of the placenta, as other exogenous materials, they can invade the tissue in depth by several transport mechanisms, both active and passive, that are not clearly understood yet.”
The range in location and characteristics of the particles found in the study suggest that passage of MPs into the placenta may be affected by physiological conditions and genetics, as well as food and lifestyle habits of the patients, the researchers said.
The study findings were limited by several factors including the small sample size and observational study design.
However, the presence of MPs in the placenta could affect the pregnancy in various ways, including immunity, growth factor signaling, maternal-fetal communication, and trafficking of various cell types and macrophages, the researchers wrote. In addition, MPs could have a transgenerational effect on metabolism and reproduction.
“Further studies need to be performed to assess if the presence of MPs in human placenta may trigger immune responses or may lead to the release of toxic contaminants, resulting harmful for pregnancy,” they concluded.
Cause for concern, but research gaps remain
“Microplastics are ubiquitous in the environment and are detectable in tissues of humans and wildlife,” Andrea C. Gore, PhD, of the University of Texas, Austin, said in an interview. “To my knowledge, this was never previously shown in the placenta.
“There are two reasons why detection of microplastics in placenta would be concerning,” Dr. Gore explained. “First, microplastics may be endocrine-disrupting chemicals (EDCs), or they may concentrate other chemicals that are EDCs. Second, the developing fetus is exquisitely sensitive to natural hormones, and disruptions by EDCs may lead to both immediate as well as latent health problems.
“Clinicians should be concerned about particulate matter in the placenta, “although the number of particles was very small,” said Dr. Gore. “Out of six women, four had particles in their placentas (total of 12) of which one was confirmed to be a plastic (polypropylene). For the other 11 particles, only the pigments could be identified, so more work is needed to confirm whether they were plastics.
“If I were a clinician discussing this article with my patients, I would point out that, although it is concerning that microparticles are present in placenta, few of them were found, and it is not known whether any chemical is released from the particles or actually reaches the fetal circulation,” Dr. Gore said. “I would use it as a starting point for a conversation about lifestyle during pregnancy and encouraging pregnant women to avoid eating foods stored and/or prepared in plastics.”
The limitations of the study include not only the small sample size, but also that “the type of chemicals in the microplastics is for the most part unknown, making it difficult to assess which (if any) might be EDCs,” Dr. Gore emphasized. In addition, “lifestyle and diet can greatly affect exposures to chemicals, so this needs to be carefully factored into the analysis.” Also, “most of the detected particles are pigments, so connections to plastics (other than the one polypropylene particle) need to be strengthened,” she explained.
“The pathways by which microplastics might get into tissues are still rather speculative, and the mechanisms proposed by the authors (endocytosis, paracellular diffusion, entry via airways) need to be demonstrated,” Dr. Gore concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Gore had no conflicts to disclose.

IBD patients more likely to stick with vedolizumab than anti-TNF drugs
Adults with inflammatory bowel disease were more likely to continue using vedolizumab, compared with anti–tumor necrosis factor (TNF) drugs over 3 years, based on data from a retrospective study of nearly 16,000 patients.
Patient persistence with prescribed therapy is essential to managing chronic inflammatory bowel disease (IBD), but data on the persistence of patients with treatments are limited, wrote Ulf Helwig, MD, of the Practice for Internal Medicine, Oldenburg, Germany, and colleagues. “With the advent of vedolizumab, physicians for the first time had the choice between biologicals with different modes of action,” they wrote.
In a study published in the Journal of Clinical Gastroenterology, the researchers used a national prescription database to identify 15,984 adults aged 18 years and older who were treatment-naive to biologics and received prescriptions between July 2014 and March 2017. Treatment persistence was defined as continuous treatment time of at least 90 days without prescription.
A total of 2,076 vedolizumab patients were matched with 2,076 adalimumab patients; 716 vedolizumab patients were matched with 716 golimumab patients; and 2,055 vedolizumab patients were matched with 2,055 infliximab patients.
Within 3 years after the first prescription, the overall persistence rates were 35.9% for vedolizumab, 27.8% for adalimumab, 20.7% for golimumab, and 29.8% for infliximab.
In matched-pair analysis, 35.2% of vedolizumab patients were persistent, compared with 28.9% of adalimumab patients over a 3-year period; the difference was statistically significant. In addition, 30.5% of vedolizumab patients persisted, compared with 25.4% of golimumab patients, also statistically significant. A matched-pair comparison between vedolizumab and infliximab (35.7% vs. 30.2%) was not statistically significant (P = 0.119).
In addition, vedolizumab patients were significantly less likely to discontinue therapy, compared with both adalimumab and golimumab patients, with hazard ratios of 0.86 and 0.60, respectively, in the matched pair analysis; discontinuation, compared with infliximab, was not statistically significant.
“Several reasons may account for significant rates of discontinuation reported for all biological treatments in IBD,” the researchers noted. “These comprise differences in health care systems in the concerned countries, including differences in availability of biologicals, access to reimbursed drugs, or different patient care settings,” they wrote.
The study findings were limited by several factors including the lack of data on specific IBD diagnoses, IBD severity, disease course, and dose escalation, they noted.
However, the study was strengthened by the large sample size and use of a real-world setting, they said.
“Further studies are needed to identify the reasons for persistence differences between vedolizumab and anti-TNF drugs,” they concluded.
Comparisons inform choices
“There are multiple biologic options for therapy of inflammatory bowel disease, and response to therapy tends to drop off over time in many patients for a variety of reasons including development of antibodies and escape from the mechanism of the action of the drug,” said Kim L. Isaacs, MD, of the University of North Carolina at Chapel Hill, in an interview.
“Intolerance or side effects of medication also may lead to discontinuation of therapy,” said Dr. Isaacs. “This trial looks at therapy discontinuation among four biologics used for inflammatory bowel disease over a 3-year period after initiation of therapy in patients who were previous biologically naive. Reasons for discontinuation cannot be assessed with this data set,” she noted. “There are very few comparative trials with the different biologic therapies in IBD. This trial is important because it compares the two distinct biologic mechanisms of action and continuation of therapy in biologically naive patients,” she said.
Dr. Isaacs said she was not surprised by the study findings. “Discontinuation of anti-TNF therapy was more common, compared to vedolizumab and golimumab. There was no statistical difference in terms of therapy discontinuation with infliximab,” she said. “In general, vedolizumab is felt to be less systemically immunosuppressant with targeting of white blood cell trafficking to the gut, whereas anti-TNF therapy is more systemically immunosuppressant and may be associated with more systemic side effects,” she explained.
The study design does not allow for comment on comparative efficacy, “although the findings are intriguing,” said Dr. Isaacs. “If the discontinuations were caused by lack of efficacy, the findings in this study may help in positioning biologic therapy in the biologic-naive patients,” she said.
The study is “a ‘real-world’ experiment that suggests there is a difference between different biologic therapies for inflammatory bowel disease,” said Dr. Isaacs. “More controlled comparative efficacy trials are needed that can look at reasons for drug discontinuation between different populations. To date, the VARSITY trial comparing vedolizumab to adalimumab in ulcerative colitis is the only published trial to do this,” she added.
The study received no outside funding. Lead author Dr. Helwig disclosed lecture and consulting fees from AbbVie, Amgen, Biogen, Celltrion, Hexal, MSD, Ferring, Falk Foundation, Takeda, Mundipharma, Pfizer, Hospira, and Vifor Pharma. Dr. Isaacs disclosed serving on the Data and Safety Monitoring Board (DSMB) for Janssen.

Anorexia and diarrhea top list of GI symptoms in COVID-19 patients
Patients with severe COVID-19 were significantly more likely than those with milder cases to have GI symptoms of anorexia and diarrhea, as well as abnormal liver function, based on data from a meta-analysis of more than 4,500 patients.
Previous studies have shown that liver damage “was more likely to be observed in severe patients during the process of disease,” and other studies have shown varying degrees of liver insufficiency in COVID-19 patients, but gastrointestinal symptoms have not been well studied, wrote Zi-yuan Dong, MD, of China Medical University, Shenyang City, and colleagues.
In a study published in the Journal of Clinical Gastroenterology, the researchers identified 31 studies including 4,682 COVID-19 patients. Case collection was from Dec. 11, 2019, to Feb. 28, 2020. Median age among studies ranged from 36 to 62 years, and 55% of patients were male.
A total of 26 studies were analyzed for the prevalence of GI symptoms, specifically nausea, vomiting, diarrhea, abdominal pain, and anorexia. Of these, anorexia and diarrhea were significantly more common in COVID-19 patients, with prevalence of 17% and 8% respectively, (P < .0001 for both).
In addition, 14 of the studies included in the analysis assessed the prevalence of abnormal liver function based on increased levels of aspartate aminotransferase, alanine aminotransferase, and total bilirubin. Of these, increased alanine aminotransferase was the most common, occurring in 25% of patients, compared with increased AST (in 24%) and total bilirubin (in 13%).
When assessed by disease severity, patients with severe disease and those in the ICU were significantly more likely than general/non-ICU patients to have anorexia (odds ratio, 2.19), diarrhea (OR, 1.65), and abdominal pain (OR, 6.38). The severely ill patients were significantly more likely to have increased AST and ALT (OR, 2.98 and 2.66, respectively).
“However, there were no significant differences between severe/ICU group and general/non-ICU group for the prevalence of nausea and vomiting and liver disease,” the researchers said.
The study findings were limited by several factors including the unclear classification of digestive system disease and liver disease in many of the studies, the small sample sizes, and the lack of data on pathology of the liver or colon in COVID-19 patients, the researchers noted.
More research is needed, but the findings suggest that COVID-19 could contribute to liver damage because the most significant abnormal liver function was increased ALT, they said.
Check liver function in cases with GI symptoms
“COVID patients can present asymptomatically or with nonspecific symptoms, including GI symptoms,” said Ziad F. Gellad, MD, of Duke University Medical Center, Durham, N.C., in an interview. “While the focus of management naturally is directed to the pulmonary consequences of the disease, it is important to evaluate the patient holistically,” he said.
“I do not think these findings have profound clinical implications because they identify relatively nonspecific symptoms that are commonly seen in patients in a number of other conditions,” noted Dr. Gellad. “The management of COVID should not change, with the exception of perhaps making sure to check for abnormal liver function tests in patients that present with more typical COVID symptoms,” he said.
“Additional research is needed to understand the biologic mechanism by which COVID impacts systems outside of the lungs,” Dr. Gellad emphasized. “For example, there has been some very interesting work understanding the impact of COVID on the pancreas and risk for pancreatitis. That work is similarly needed to understand how COVID, outside of causing a general illness, specifically impacts the rest of the GI tract,” he said.
The study was supported by the Liaoning Science and Technology Foundation. The researchers had no financial conflicts to disclose. Dr. Gellad had no financial conflicts to disclose.

Patients with severe COVID-19 were significantly more likely than those with milder cases to have GI symptoms of anorexia and diarrhea, as well as abnormal liver function, based on data from a meta-analysis of more than 4,500 patients.
Previous studies have shown that liver damage “was more likely to be observed in severe patients during the process of disease,” and other studies have shown varying degrees of liver insufficiency in COVID-19 patients, but gastrointestinal symptoms have not been well studied, wrote Zi-yuan Dong, MD, of China Medical University, Shenyang City, and colleagues.
In a study published in the Journal of Clinical Gastroenterology, the researchers identified 31 studies including 4,682 COVID-19 patients. Case collection was from Dec. 11, 2019, to Feb. 28, 2020. Median age among studies ranged from 36 to 62 years, and 55% of patients were male.
A total of 26 studies were analyzed for the prevalence of GI symptoms, specifically nausea, vomiting, diarrhea, abdominal pain, and anorexia. Of these, anorexia and diarrhea were significantly more common in COVID-19 patients, with prevalence of 17% and 8% respectively, (P < .0001 for both).
In addition, 14 of the studies included in the analysis assessed the prevalence of abnormal liver function based on increased levels of aspartate aminotransferase, alanine aminotransferase, and total bilirubin. Of these, increased alanine aminotransferase was the most common, occurring in 25% of patients, compared with increased AST (in 24%) and total bilirubin (in 13%).
When assessed by disease severity, patients with severe disease and those in the ICU were significantly more likely than general/non-ICU patients to have anorexia (odds ratio, 2.19), diarrhea (OR, 1.65), and abdominal pain (OR, 6.38). The severely ill patients were significantly more likely to have increased AST and ALT (OR, 2.98 and 2.66, respectively).

Pregnant women using substances need support
according to a panel of experts speaking at the 2020 virtual meeting of the American College of Obstetricians and Gynecologists. The panelists highlighted several key issues for addressing alcohol, opioids, and cannabis use by pregnant women.
No amount of alcohol is safe
Many women believe that a limited amount of alcohol is safe during pregnancy, in part because of mixed messages in the media suggesting that light drinking is okay, according to Erin Tracy Bradley, MD, MPH, of Massachusetts General Hospital, Boston.
“We need to do a better job teaching our patients about the potential dangers of alcohol,” Dr. Bradley said in her presentation.
In fact, data suggest that women more at risk for an alcohol-exposed pregnancy are older and better educated. Dr. Bradley described the pattern of malformation for fetal alcohol syndrome (FAS) that includes small eyes, a thin upper lip, and smooth skin between the upper lip and nose.
“The only cause we know of [for FAS] is alcohol exposure intrauterine for the fetus,” so it is preventable with counseling and care, and thought to be the leading preventable cause of birth defects during pregnancies, she said.
The bottom line is that there is no safe amount of alcohol,” said Dr. Bradley. However, providers are inconsistent in discussing alcohol with their pregnant patients. In addition, universal screening is important because it is difficult to predict which women will be drinking during pregnancy.
Screening allows providers to quickly assess the severity of substance use, offer a brief intervention to raise patient awareness, and refer if necessary. “There should be ‘absolutely no judgment, no shame, no stigma,’ ” Dr. Bradley emphasized. “We are the patient’s partners, and we are trying to help them have a healthy pregnancy. “
Opioid use in pregnancy spiked in recent decades
“Women have always been overrepresented when opioids are involved,” said Tricia E. Wright, MD, of the University of California, San Francisco.
Long-term studies have shown that, overall, women are more likely to be given opioids and given higher doses, compared with men, often for conditions in which opioids are not effective, she noted.
Women use substances differently than men; “they use them to cope with everyday life,” and a history of interpersonal violence and sexual assault are coming among women with opioid use disorders, said Dr. Wright.
The majority of women with opioid use disorders are of childbearing age, which has led to an increase in neonatal abstinence syndrome (NAS) said Dr. Wright.
She cited 2014 data from the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report showing an increase in NAS from 1.2 per 1,000 hospital births in 2000 to 5.8 per 1,000 hospital births in 2012. This increase has led to “misguided” efforts to prevent NAS through opioid detoxification, Dr. Wright said. She and colleagues conducted a systematic review in 2018 and found that, in fact, the evidence does not support detoxification as a recommended treatment intervention during pregnancy.
Opioid agonist therapy has multiple benefits for both the mother and fetus, Dr. Wright said. Maternal benefits include reduction in overdose-related deaths; decrease in the risk of HIV, hepatitis B, and hepatitis C; and increased engagement in prenatal care and recovery treatment. Fetal benefits include reduced fetal stress with the reduced fluctuations in maternal opioid levels, as well as decreases in intrauterine fetal death, intrauterine growth restriction, and preterm delivery.
“We know that relapse kills” because patients lose their tolerance, Dr. Wright said. “What we have seen is that overdose deaths are a leading cause of death in the postpartum period.”
When it comes to treatment, both methadone and buprenorphine are safe and effective options in pregnancy, she said. Treatment decisions should be made based on available options, patient preference, and a patient’s previous treatment experiences, as well as disease severity, social support, and the intensity of treatment needed.
“Whatever medicine you choose, it takes a village to coordinate the care,” Dr. Wright said. Maternal dose has no effect on neonatal withdrawal, so women should be encouraged to report any concerns. Either medication is compatible with breastfeeding. In fact, breastfeeding has many benefits in preventing neonatal withdrawal syndrome. Smoking cessation should be encouraged because it improves neonatal withdrawal.
Minimizing stigma is paramount, said Dr. Wright. “Substance use disorders are among the most stigmatized medical conditions, and pregnant women with substance use disorders are even more stigmatized.”
Clinicians can support patients by focusing on appropriate language, patients aren’t “addicts,” they are people with an opioid use disorder, she said.
Compassionate care for cannabis users
Cannabis use has a long history of association with women’s health, said Mishka Terplan, MD, MPH, of Friends Research Institute, Baltimore. Although cannabis use overall has increased steadily in recent years, data indicate that people who are pregnant are less likely to use cannabis than those who aren’t. The exception is that individuals who report using cannabis for medical purposes only remain consistent cannabis users during pregnancy.
“The concern is cannabis and birth outcomes, as well as developmental outcomes,” Dr. Terplan said. Multiple studies on this topic support several systematic reviews, and “depending on which decade you read, the results differ slightly.”
Reviews from the 1990s showed little to no effect on birth weight, but more recent studies, such as a meta-analysis published in BMJ Open in 2015, showed increased risk of neonatal outcomes such as low birth weight, anemia, and odds of admission to the neonatal ICU.
“The difference in these two eras is thought to be caused by the change in the definition of what cannabis is, and the potency has increased, and possibly therefore, as a consequence, we see outcomes we hadn’t seen before,” Dr. Terplan explained.
There is a concern with increased use and increased legalization that, there could be adverse effects on neonatal health, but recent studies in Colorado do not show a significant difference in neonatal outcomes before and after legalization, he said.
Data from pregnant women suggest that with regard to cannabis, they are concerned about their health, but they tend to seek information about cannabis use in pregnancy from family, friends, and the Internet rather than their health providers, said Dr. Terplan.
However, studies also show that providers tend to fall short and do a poor job of talking to pregnant patients about cannabis. When providers do discuss cannabis, they tend to focus on the legal aspects. “We are failing our patients when it comes to cannabis,” Dr. Terplan said. “We don’t provide the information and support they need and desire.” Instead, many providers “deploy urine drug testing, which we misinterpret.”
Dr. Terplan explained that point-of-care cannabis testing that shows “THC” is not measuring tetrahydrocannabinol, the psychoactive compound; rather it captures the nonpsychoactive metabolite of THC, one that sticks around for a long time in the biological compartment.
Dr. Terplan urged clinicians not to use urine tests as a default indicator of cannabis use, but instead, “we need to sit, listen, and work with our patients from a place of empathy.”
Questions answered
During a question-and-answer session following the panel, Dr. Bradley was asked about preconception counseling related to alcohol consumption.
“Preconception time is a perfect time to do screening, or offer contraception if a patient is a place where she doesn’t want to become pregnant or if she wants to take advantage of any therapeutic options to get well prior to pregnancy,” she said.
Dr. Wright responded to a question about the impact of punitive actions such as drug testing and incarceration. “These things decrease the chance that patients will get adequate prenatal care,” she said. “We need to advocate for our patients and advocate for changing drug laws.”
Dr. Terplan responded to a question about the impact of substance use on parenting. Parents use nicotine, alcohol, and also cannabis, he said. Data showing an association between substance use and cases of child abuse and neglect, “are of poor quality and do not support this association.”
Overall, “we need to have consistent messaging that we are not there to judge patients,” Dr. Bradley added. “The last thing we want is for patients not to be honest with us.”
Dr. Wright disclosed consulting fees from McKesson and royalties as the coauthor of a book, “Opioid-Use Disorders in Pregnancy.” Dr. Bradley had no financial conflicts to disclose. Dr. Terplan had no financial conflicts to disclose.

FROM ACOG 2020
Histologic remission fails to be related to UC relapse
Relapse in ulcerative colitis patients with endoscopic remission was unaffected by histologic remission status, based on data from a retrospective study of 269 adults.
Data from previous studies suggest that histologic remission may be the strongest predictor of prognosis of disease course, wrote Neeraj Narula, MD, of McMaster University, Hamilton, Ont., and colleagues.
“However, it is unclear if UC patients who have achieved endoscopic healing have additional benefit in clinical outcomes if they have achieved histologic remission as well compared to those with ongoing histology activity,” they said.
In a study published in Alimentary Pharmacology and Therapeutics, the researchers identified 269 adults with ulcerative colitis who had endoscopic remission. Of these, 53 had normal histology, 138 had histologically inactive colitis, and 78 had histologically active colitis.
Overall, clinical relapse occurred in 64 patients, including 12 with normal histology (22.6%), 32 with inactive colitis (23.2%), and 29 with active colitis (25.6%).
No significant difference occurred in the time to relapse in patients with inactive vs. active colitis (adjusted hazard ratio 1.17, P = .67) or in patients with normal histology vs. inactive histology (AHR 0.67, P = .39). The median time to relapse was 2.92 years, 3.0 years, and 4.0 years in the normal, inactive, and active groups, respectively. Factors associated with a shorter time to relapse included older age at colonoscopy, use of 5-aminosalicylic acid, and disease extent in cases of pancolitis and left-sided colitis.
The study findings were limited by several factors including the possibility of bias in histologic scoring, lack of objective measures of disease activity, and the lack of uniformity is histologic assessment, the researchers noted. However, the results were strengthened by the large size compared with previous studies and by the adjustments for known confounding factors, they said.
“While clinical and endoscopic remission [is the target] of therapy for patients with UC, our study does not support targeting histologic remission in patients who have already achieved endoscopic remission,” they concluded.
More research may support clinical applications
“I was rather surprised by the findings, as a majority of studies have shown that histologic healing more accurately predicts clinical relapse than endoscopic remission in UC,” Atsushi Sakuraba, MD, of the University of Chicago, said in an interview.
“Although of a good sample size, this was a retrospective study, so no firm conclusion can be made,” said Dr. Sakuraba. “Using histologic healing as a therapeutic goal is still an evolving field, and it is too early to draw a conclusion as to whether (or not) to introduce histologic healing in clinical decision making,” he emphasized.
Going forward, prospective studies are needed that match for confounders such as postendoscopy medication use, age, and disease extent, Dr. Sakuraba said.
The study received no outside funding. Lead author Dr. Narula disclosed honoraria from Janssen, AbbVie, Takeda, Pfizer, Merck, and Ferring. Dr. Sakuraba had no financial conflicts to disclose.

Relapse in ulcerative colitis patients with endoscopic remission was unaffected by histologic remission status, based on data from a retrospective study of 269 adults.
Data from previous studies suggest that histologic remission may be the strongest predictor of prognosis of disease course, wrote Neeraj Narula, MD, of McMaster University, Hamilton, Ont., and colleagues.
“However, it is unclear if UC patients who have achieved endoscopic healing have additional benefit in clinical outcomes if they have achieved histologic remission as well compared to those with ongoing histology activity,” they said.

IBD patients more likely to stick with vedolizumab than anti-TNF drugs
Adults with inflammatory bowel disease were more likely to continue using vedolizumab, compared with anti–tumor necrosis factor (TNF) drugs over 3 years, based on data from a retrospective study of nearly 16,000 patients.
Patient persistence with prescribed therapy is essential to managing chronic inflammatory bowel disease (IBD), but data on the persistence of patients with treatments are limited, wrote Ulf Helwig, MD, of the Practice for Internal Medicine, Oldenburg, Germany, and colleagues. “With the advent of vedolizumab, physicians for the first time had the choice between biologicals with different modes of action,” they wrote.
In a study published in the Journal of Clinical Gastroenterology, the researchers used a national prescription database to identify 15,984 adults aged 18 years and older who were treatment-naive to biologics and received prescriptions between July 2014 and March 2017. Treatment persistence was defined as continuous treatment time of at least 90 days without prescription.
A total of 2,076 vedolizumab patients were matched with 2,076 adalimumab patients; 716 vedolizumab patients were matched with 716 golimumab patients; and 2,055 vedolizumab patients were matched with 2,055 infliximab patients.
Within 3 years after the first prescription, the overall persistence rates were 35.9% for vedolizumab, 27.8% for adalimumab, 20.7% for golimumab, and 29.8% for infliximab.
In matched-pair analysis, 35.2% of vedolizumab patients were persistent, compared with 28.9% of adalimumab patients over a 3-year period; the difference was statistically significant. In addition, 30.5% of vedolizumab patients persisted, compared with 25.4% of golimumab patients, also statistically significant. A matched-pair comparison between vedolizumab and infliximab (35.7% vs. 30.2%) was not statistically significant (P = 0.119).
In addition, vedolizumab patients were significantly less likely to discontinue therapy, compared with both adalimumab and golimumab patients, with hazard ratios of 0.86 and 0.60, respectively, in the matched pair analysis; discontinuation, compared with infliximab, was not statistically significant.
“Several reasons may account for significant rates of discontinuation reported for all biological treatments in IBD,” the researchers noted. “These comprise differences in health care systems in the concerned countries, including differences in availability of biologicals, access to reimbursed drugs, or different patient care settings,” they wrote.
The study findings were limited by several factors including the lack of data on specific IBD diagnoses, IBD severity, disease course, and dose escalation, they noted.
However, the study was strengthened by the large sample size and use of a real-world setting, they said.
“Further studies are needed to identify the reasons for persistence differences between vedolizumab and anti-TNF drugs,” they concluded.
Comparisons inform choices
“There are multiple biologic options for therapy of inflammatory bowel disease, and response to therapy tends to drop off over time in many patients for a variety of reasons including development of antibodies and escape from the mechanism of the action of the drug,” said Kim L. Isaacs, MD, of the University of North Carolina at Chapel Hill, in an interview.
“Intolerance or side effects of medication also may lead to discontinuation of therapy,” said Dr. Isaacs. “This trial looks at therapy discontinuation among four biologics used for inflammatory bowel disease over a 3-year period after initiation of therapy in patients who were previous biologically naive. Reasons for discontinuation cannot be assessed with this data set,” she noted. “There are very few comparative trials with the different biologic therapies in IBD. This trial is important because it compares the two distinct biologic mechanisms of action and continuation of therapy in biologically naive patients,” she said.
Dr. Isaacs said she was not surprised by the study findings. “Discontinuation of anti-TNF therapy was more common, compared to vedolizumab and golimumab. There was no statistical difference in terms of therapy discontinuation with infliximab,” she said. “In general, vedolizumab is felt to be less systemically immunosuppressant with targeting of white blood cell trafficking to the gut, whereas anti-TNF therapy is more systemically immunosuppressant and may be associated with more systemic side effects,” she explained.
The study design does not allow for comment on comparative efficacy, “although the findings are intriguing,” said Dr. Isaacs. “If the discontinuations were caused by lack of efficacy, the findings in this study may help in positioning biologic therapy in the biologic-naive patients,” she said.
The study is “a ‘real-world’ experiment that suggests there is a difference between different biologic therapies for inflammatory bowel disease,” said Dr. Isaacs. “More controlled comparative efficacy trials are needed that can look at reasons for drug discontinuation between different populations. To date, the VARSITY trial comparing vedolizumab to adalimumab in ulcerative colitis is the only published trial to do this,” she added.
The study received no outside funding. Lead author Dr. Helwig disclosed lecture and consulting fees from AbbVie, Amgen, Biogen, Celltrion, Hexal, MSD, Ferring, Falk Foundation, Takeda, Mundipharma, Pfizer, Hospira, and Vifor Pharma.

Shortcomings identified in study of acne videos on TikTok
, according to an analysis of the top 100 videos using a consumer health validation tool.
The popularity of TikTok among adolescents in particular has implications for the dissemination of acne information, as some teens become “skinfluencers” and receive sponsorship from skin care brands in exchange for social media promotion, wrote David X. Zheng, BA, of the department of dermatology, Case Western Reserve University, Cleveland, and colleagues.
“However, the quality of dermatologic information found on TikTok is largely unknown,” they said.
In a brief report published in Pediatric Dermatology, the researchers identified the top 100 videos on TikTok on May 1, 2020, that were tagged with “#acne.” The information on each video included date of upload, type and gender of the individual uploading the video, physician specialty if applicable, and video category. These top 100 videos had 13,470,501 likes and 64,775 comments over a 7.6-month time period.
The researchers used the DISCERN criteria, a validated 1-5 scale designed to assess consumer health information, to evaluate the video content, with 1 (having “serious” or “extensive shortcomings”) and 5 (having “minimal shortcomings.”)
Overall, the average quality rating of the TikTok acne videos was 2.03. A total of 9 videos were produced by board-certified physicians in the United States, with an average DISCERN score of 2.41.
“Analysis of the DISCERN criteria dimensions suggested that major shortcomings common to both physician and nonphysician uploaders included failure to cite information sources, discuss treatment risks, and provide support for shared decision-making,” the researchers said.
Approximately one-third (34%) of the videos fell into the treatment-product advertisement category, while 26% were personal anecdotes, 20% presented information related to acne, 13% featured home remedy treatments, and 7% were classified as “other.” The researchers also identified the top 200 “#acne” videos on TikTok once a week from May 8, 2020 to June 5, 2020, to determine the evolution of acne content on the app and found a turnover rate of 10.9% per week.
Based on the high turnover and low quality based on DISCERN ratings, the authors suggested that patients seeking acne information should “view acne-related TikTok videos with caution and consult evidence-based resources whenever possible.”
The study findings were limited by several factors including the small sample size of physicians uploading videos, lack of information about the number of nonphysician medical professionals who uploaded videos, and lack of information about the number of video views and country of origin, the researchers noted. However, the results highlight the need for dermatologists to be aware that patients, especially teens, may be using TikTok for acne information that may be of poor quality, they said.
“Conversely, we understand that social media can be a powerful tool for advancing health literacy,” the researchers noted. “Therefore, we also recommend that health care professionals engaging on TikTok create thorough and perhaps standardized educational videos regarding acne, as well as correct any acne-related misinformation that may be present,” they concluded.
The other authors of the study were from the departments of dermatology at Case Western Reserve, University Hospitals Cleveland, and Johns Hopkins University, Baltimore.
The study received no outside funding. The researchers had no financial conflicts to disclose.

The researchers used the DISCERN criteria, a validated 1-5 scale designed to assess consumer health information, to evaluate the video content, with 1 (having “serious” or “extensive shortcomings”) and 5 (having “minimal shortcomings.”)
Overall, the average quality rating of the TikTok acne videos was 2.03. A total of 9 videos were produced by board-certified physicians in the United States, with an average DISCERN score of 2.41.
“Analysis of the DISCERN criteria dimensions suggested that major shortcomings common to both physician and nonphysician uploaders included failure to cite information sources, discuss treatment risks, and provide support for shared decision-making,” the researchers said.
Approximately one-third (34%) of the videos fell into the treatment-product advertisement category, while 26% were personal anecdotes, 20% presented information related to acne, 13% featured home remedy treatments, and 7% were classified as “other.” The researchers also identified the top 200 “#acne” videos on TikTok once a week from May 8, 2020 to June 5, 2020, to determine the evolution of acne content on the app and found a turnover rate of 10.9% per week.
Based on the high turnover and low quality based on DISCERN ratings, the authors suggested that patients seeking acne information should “view acne-related TikTok videos with caution and consult evidence-based resources whenever possible.”
The study findings were limited by several factors including the small sample size of physicians uploading videos, lack of information about the number of nonphysician medical professionals who uploaded videos, and lack of information about the number of video views and country of origin, the researchers noted. However, the results highlight the need for dermatologists to be aware that patients, especially teens, may be using TikTok for acne information that may be of poor quality, they said.
“Conversely, we understand that social media can be a powerful tool for advancing health literacy,” the researchers noted. “Therefore, we also recommend that health care professionals engaging on TikTok create thorough and perhaps standardized educational videos regarding acne, as well as correct any acne-related misinformation that may be present,” they concluded.
The other authors of the study were from the departments of dermatology at Case Western Reserve, University Hospitals Cleveland, and Johns Hopkins University, Baltimore.
The study received no outside funding. The researchers had no financial conflicts to disclose.

Labor induction at 39 weeks may improve neonatal outcomes
Aaron B. Caughey, MD, PhD, said at the 2020 virtual meeting of the American College of Obstetricians and Gynecologists.
For much of the 20th century, term gestation has been defined as 37 weeks and beyond, said Dr. Caughey, of Oregon Health & Science University, Portland. He noted several studies showing a U-shaped distribution in neonatal outcomes during the period from 37 weeks to 41 weeks for some outcomes, including Apgar scores. However, respiratory outcomes in a study from 2008 showed an increase, with meconium stained amniotic fluid increasing from 2.27% at 37 weeks to 10.33% at 41 weeks, and meconium aspiration increasing from 0.07% at 37 weeks to 0.27% at 41 weeks.
Late-term induction may carry more risk
The study “that really got everyone’s attention” in terms of neonatal outcomes was published in 2009 in the New England Journal of Medicine. The cohort study included 24,077 elective cesarean deliveries between 37 and 42 weeks and reviewed a range of neonatal outcomes based on gestational age.
The rate of any adverse outcome decreased from 37 weeks to 39 weeks, “but then started going back up again,” Dr. Caughey said. He reviewed data from another study that factored in stillbirth and the risk of expectant management based on gestational age. A composite risk of perinatal death with expectant management was 15.4 deaths per 10,000 cases at 37 weeks and 39 weeks, but increased to 19.9 at 42 weeks.
“The morbidity appears to have a U-shaped distribution and the mortality seems to favor delivery at 39 weeks,” he said.
When it comes to induction of labor, medically indicated vs. nonmedically indicated does matter, Dr. Caughey said. Factors not considered a medical indication include impending macrosomia, increased risk for developing preeclampsia or intrauterine growth retardation, and a favorable cervix, he noted.
“For indicated induction of labor, the risks and benefits of induction of labor vs. expectant management have been considered and weighed in by the field of experts that care for pregnant women,” he said. With nonmedically indicated induction, experts “either decided that risks and benefits don’t favor induction of labor, or we haven’t come down hard on what the protocol might be.
“It is important to consider the risks and benefits,” said Dr. Caughey. The factors you want to include are neonatal outcomes, maternal preferences, and doctor preferences. However, “we want to be thoughtful about this intervention,” because of the association of higher costs and increased risk of cesarean with induction of labor.
As for timing of induction of labor, certain conditions favoring early-term induction include preeclampsia and gestational hypertension, chronic hypertension, diabetes, intrauterine growth restriction, nonreassuring fetal testing, cholestasis, placenta previa or accreta, and twins.
Data support value of 39 weeks
As for late-term induction of labor, “at 41 weeks it is pretty clear that neonatal outcomes would be improved by delivery,” he said. Historically, clinicians have raised concerns about the increased risk of cesarean delivery following induction of labor, but this risk has not been borne out in recent studies. Dr. Caughey said. However, in the findings from the ARRIVE trial, a large study of 6,106 women who were randomized to induction or labor or expectant management at 39 weeks, “they found a reduction in their risk of cesarean delivery compared to expectant management (18.6% vs. 22.2%). Rates of preeclampsia also were lower among induced women, while rate of chorioamnionitis, postpartum hemorrhage, and intensive care were similar between the groups. The researchers did not find significant differences in perinatal outcomes.
Dr. Caughey and colleagues conducted a systematic review of cesarean risk and induction of labor, and found a risk ratio of 0.83, similar to the ARRIVE trial. “The data suggest a consistently reduced risk for cesarean delivery with the induction of labor.”
However, “I would caution us to be thoughtful about research protocols vs. actual practice,” he said. “You must think about the environment.” The latent phase of labor can continue for a long time after induction, and patience is called for, he emphasized.
Dr. Caughey said that despite the ARRIVE trial and other studies, 39 weeks should not necessarily be the new standard for induction of labor. “The proportion of women impacted is dramatically different, if you would be inducing every woman at 39 weeks, that would be 60% to 70%,” which could have a great impact on resources.
Based on current research, early-term induction of labor at 37 weeks “is a bad idea without indication,” said Dr. Caughey. Induction at 41 weeks (sometimes considered post term) is the current ACOG recommendation and is associated with improved outcomes.
Induction of labor at full term (39-40 weeks) depends in part on the environment, and is not a violation of standard of care, he said. “Evidence is evolving, and individual hospitals are trying to figure this out.”
Cesarean data are convincing, at least in some settings, he said. However, “we need more global trials and different medical settings” to determine the optimal time for induction of labor.
Consider maternal preferences and characteristics
During a question-and-answer session, Dr. Caughey was asked whether all women should be offered induction of labor at 39 weeks.
“I think it is OK if your entire health system has agreed to offering, to have that shared medical decision making, but you need to have careful conversation to make sure you have the resources,” he noted. Also, he said he believed clinicians should respond to women as they request labor induction at 39 weeks.
In response to a question about induction of labor in obese women, he noted that women with a body mass index greater than 35 kg/m2 are not equally successful with induction of labor. “We know they have a higher risk of cesarean delivery,” however, “it has been demonstrated that they have the same potential benefits of reduced risk of cesarean.”
As for factoring in the Bishop score to determine a favorable or unfavorable cervix, Dr. Caughey noted that women with a favorable cervix are more likely to go into labor on their own, while those with an unfavorable cervix may benefit from cervical ripening.
Dr. Caughey had no financial conflicts relevant to this talk, but disclosed serving as a medical adviser to Celmatix and Mindchild, as well as an endowment to his academic department from Bob’s Red Mill, an Oregon-based whole grain foods manufacturer.

EXPERT ANALYSIS FROM ACOG 2020
Nicotine vaping tapers off among teens
Levels of nicotine and marijuana vaping among adolescents remain elevated but did not increase significantly in the past year, data from the annual Monitoring the Future survey show.
The 2020 survey included responses from 11,821 individuals in 112 schools across the United States from Feb. 11, 2020, to March 14, 2020, at which time data collection ended prematurely because of the COVID-19 pandemic.
A key positive finding in this year’s survey was the relatively stable levels of nicotine vaping from 2019 to 2020, following a trend of notably increased use annually since vaping was added to the survey in 2017.
During the years 2017-2019, the percentage of teens who reported vaping nicotine in the past 12 months increased from 7.5% to 16.5% among 8th graders, from 15.8% to 30.7% among 10th graders, and from 18.8% to 35.3% among 12th graders. However, in 2020, the percentages of teens who reported past-year nicotine vaping were relatively steady at 16.6%, 30.7%, and 34.5%, for 8th-, 10th-, and 12th-grade students, respectively. In addition, reports of daily or near-daily nicotine vaping (defined as 20 occasions in the past 30 days) decreased significantly, from 6.8% to 3.6% among 10th graders and from 11.6% to 5.3% among 12th graders.
“The rapid rise of teen nicotine vaping in recent years has been unprecedented and deeply concerning since we know that nicotine is highly addictive and can be delivered at high doses by vaping devices, which may also contain other toxic chemicals that may be harmful when inhaled,” said Nora D. Volkow, MD, director of the National Institute on Drug Abuse in a press release accompanying the release of the findings. “It is encouraging to see a leveling off of this trend though the rates still remain very high.”
Reports of past-year marijuana vaping remained similar to 2019 levels after a twofold increase in the past 2 years, according to the survey. In early 2020, 8.1%, 19.1%, and 22.1% of 8th, 10th, and 12th graders reported past-year use. However, daily marijuana vaping decreased by more than half from 2019, to 1.1% among 10th graders and 1.5% among 12th graders.
Past-year use of the JUUL devices specifically also declined among older teens, from 28.7% in 2019 to 20% in 2020 among 10th graders and from 28.4% in 2019 to 22.7% in 2020 among 12th graders.
Other trends this year included the increased past-year use of amphetamines, inhalants, and cough medicines among 8th graders, and relatively low reported use among 12th graders of LSD (3.9%), synthetic cannabinoids (2.4%), cocaine (2.9%), ecstasy (1.8%), methamphetamine (1.4%), and heroin (0.3%).
The findings were published in JAMA Pediatrics.
Early data show progress
“The MTF survey is the most referenced and reliable longitudinal study reporting current use of tobacco, drugs, and alcohol among young people,” said Mark S. Gold, MD, of Washington University, St. Louis, in an interview.
“The new data, collected before data collection stopped prematurely due to the COVID-19 pandemic, suggests that some progress is being made in slowing the increase in substance use among these, the most vulnerable,” he said.
“The best news was that nicotine vaping decreased significantly after its meteoric increase over the past few years,” Dr. Gold emphasized. “Past-year vaping of marijuana remained steady at alarming levels in 2020, with 8.1% of 8th graders, 19.1% of 10th graders, and 22.1% of 12th graders reporting past-year use, following a two-fold increase over the past 2 years.” The use of all forms of marijuana, including smoking and vaping, did not significantly change in any of the three grades for lifetime use, past 12-month use, past 30-day use, and daily use from 2019 to 2020.
“Teen alcohol use has not significantly changed over the past 5 years,” and cigarette smoking in the last 30 days did not significantly change from 2019 to 2020, said Dr. Gold. However, “as with adults, psychostimulant use is increasing. Past year nonmedical use of amphetamines among 8th graders increased, from 3.5% in 2017 to 5.3% in 2020.”
COVID-era limitations
“The data suggest that pre-COVID pandemic vaping, smoking cigarettes, marijuana, and alcohol use had stabilized,” Dr. Gold said. “However, it is very difficult to predict what the COVID era data will show as many young people are at home, on the streets, and unsupervised; while adult substance misuse, substance use disorders, and overdoses are increasing. Drug supplies and access have increased for alcohol, cannabis, vaping, and tobacco as have supply synthetics like methamphetamine and fentanyl.”
In addition, “access to evaluation, intervention, and treatment have been curtailed during the pandemic,” Dr. Gold said. “The loss of peer role models, daily routine, and teacher or other adult supervision and interventions may interact with increasing despair, social isolation, depression, and anxiety in ways that are unknown. “It will not be clear until the next survey if perceived dangerousness has changed in ways that can protect these 8th, 10th, and 12th graders and increase the numbers of never users or current nonusers.”
The Monitoring the Future survey is conducted each year by the University of Michigan’s Institute for Social Research, Ann Arbor, and supported by NIDA, part of the National Institutes of Health. Dr. Gold had no relevant financial conflicts to disclose.

The 2020 survey included responses from 11,821 individuals in 112 schools across the United States from Feb. 11, 2020, to March 14, 2020, at which time data collection ended prematurely because of the COVID-19 pandemic.
A key positive finding in this year’s survey was the relatively stable levels of nicotine vaping from 2019 to 2020, following a trend of notably increased use annually since vaping was added to the survey in 2017.
During the years 2017-2019, the percentage of teens who reported vaping nicotine in the past 12 months increased from 7.5% to 16.5% among 8th graders, from 15.8% to 30.7% among 10th graders, and from 18.8% to 35.3% among 12th graders. However, in 2020, the percentages of teens who reported past-year nicotine vaping were relatively steady at 16.6%, 30.7%, and 34.5%, for 8th-, 10th-, and 12th-grade students, respectively. In addition, reports of daily or near-daily nicotine vaping (defined as 20 occasions in the past 30 days) decreased significantly, from 6.8% to 3.6% among 10th graders and from 11.6% to 5.3% among 12th graders.
“The rapid rise of teen nicotine vaping in recent years has been unprecedented and deeply concerning since we know that nicotine is highly addictive and can be delivered at high doses by vaping devices, which may also contain other toxic chemicals that may be harmful when inhaled,” said Nora D. Volkow, MD, director of the National Institute on Drug Abuse in a press release accompanying the release of the findings. “It is encouraging to see a leveling off of this trend though the rates still remain very high.”
Reports of past-year marijuana vaping remained similar to 2019 levels after a twofold increase in the past 2 years, according to the survey. In early 2020, 8.1%, 19.1%, and 22.1% of 8th, 10th, and 12th graders reported past-year use. However, daily marijuana vaping decreased by more than half from 2019, to 1.1% among 10th graders and 1.5% among 12th graders.
Past-year use of the JUUL devices specifically also declined among older teens, from 28.7% in 2019 to 20% in 2020 among 10th graders and from 28.4% in 2019 to 22.7% in 2020 among 12th graders.
Other trends this year included the increased past-year use of amphetamines, inhalants, and cough medicines among 8th graders, and relatively low reported use among 12th graders of LSD (3.9%), synthetic cannabinoids (2.4%), cocaine (2.9%), ecstasy (1.8%), methamphetamine (1.4%), and heroin (0.3%).
The findings were published in JAMA Pediatrics.
Early data show progress
“The MTF survey is the most referenced and reliable longitudinal study reporting current use of tobacco, drugs, and alcohol among young people,” said Mark S. Gold, MD, of Washington University, St. Louis, in an interview.
“The new data, collected before data collection stopped prematurely due to the COVID-19 pandemic, suggests that some progress is being made in slowing the increase in substance use among these, the most vulnerable,” he said.
“The best news was that nicotine vaping decreased significantly after its meteoric increase over the past few years,” Dr. Gold emphasized. “Past-year vaping of marijuana remained steady at alarming levels in 2020, with 8.1% of 8th graders, 19.1% of 10th graders, and 22.1% of 12th graders reporting past-year use, following a two-fold increase over the past 2 years.” The use of all forms of marijuana, including smoking and vaping, did not significantly change in any of the three grades for lifetime use, past 12-month use, past 30-day use, and daily use from 2019 to 2020.
“Teen alcohol use has not significantly changed over the past 5 years,” and cigarette smoking in the last 30 days did not significantly change from 2019 to 2020, said Dr. Gold. However, “as with adults, psychostimulant use is increasing. Past year nonmedical use of amphetamines among 8th graders increased, from 3.5% in 2017 to 5.3% in 2020.”
COVID-era limitations
“The data suggest that pre-COVID pandemic vaping, smoking cigarettes, marijuana, and alcohol use had stabilized,” Dr. Gold said. “However, it is very difficult to predict what the COVID era data will show as many young people are at home, on the streets, and unsupervised; while adult substance misuse, substance use disorders, and overdoses are increasing. Drug supplies and access have increased for alcohol, cannabis, vaping, and tobacco as have supply synthetics like methamphetamine and fentanyl.”
In addition, “access to evaluation, intervention, and treatment have been curtailed during the pandemic,” Dr. Gold said. “The loss of peer role models, daily routine, and teacher or other adult supervision and interventions may interact with increasing despair, social isolation, depression, and anxiety in ways that are unknown. “It will not be clear until the next survey if perceived dangerousness has changed in ways that can protect these 8th, 10th, and 12th graders and increase the numbers of never users or current nonusers.”

Study links sleep meds and dementia risk in older adults
Sleep medications for older patients who report sleep problems may not be the best treatment given growing evidence of the link between these medications and the risk of incident dementia.
Adults aged 65 years and older who used sleep medications 5-7 days a week demonstrated a 30% increased risk of dementia, compared with those who did not use sleep medications, findings from a prospective study of 6,373 individuals show.
Adults aged 65 and older report a higher burden of sleep problems than other age groups, but major medical associations discourage the use of sleep medications by older adults because of growing evidence of a link between sleep medication use and cognitive decline, wrote Rebecca Robbins, MD, of Brigham and Women’s Hospital, Boston, and colleagues. However, data on this association among adults in the United States are limited, they said.
In a study published in Sleep Medicine, the researchers surveyed 6,373 adults aged 65 years and older who were enrolled in the nationally representative National Health and Aging Trends Study (NHATS). The majority of the participants were non-Hispanic White (71%), 59% were women, and 21% ranged in age from 70 to 74 years.
Participants responded to questions about routine sleep medication use. Routine was defined as “most nights” or “every night.” The data were collected for an 8-year period from 2011 to 2018. The study began in 2011, with a core interview administered annually.
Approximately 15% of the study population reported routine use of sleep medications. Overall, routine use of sleep medication was significantly associated with risk of incident dementia (hazard ratio, 1.30; P < .01) after controlling for multiple variables including age, sex, education level, and chronic conditions.
Dementia screening was conducted by participants rating their memory and then performing a memory-related activity (immediate and delayed 10-word recall) and other exercises to assess executive function and orientation. A separate eight-item informant screener was performed for patient proxies. The researcher noted, “Sensitivity of the NHATS probable dementia screening measure has been determined in previous research to be 66%, and specificity is 87%, with respect to a clinical dementia diagnosis.”
The study findings were limited by several factors including the use of self-reports, the lack of data on type or dose of sleep medication, and lack of data on the indication for the prescription, the researchers noted.
“Also, sleep medication use leads to worse performance on cognitive testing, such as the questionnaires used to screen for dementia in this study, and therefore could have resulted in a false diagnosis of dementia,” they added.
However, the results were strengthened by the large, nationally representative study population and support the need for quality geriatric care, the researchers said.
“Our findings provide further support and evidence that sleep medications are all too commonly administered, yet associated with greater risk for incident dementia, and that the U.S. health care system is in need of creative solutions for addressing poor sleep among older individuals,” they concluded.
Implications and alternatives
The study is important as the number of aging Americans increases, said Carolyn M. D’Ambrosio, MD, FCCP, of Brigham and Women’s Hospital and Harvard Medical School, Boston, in an interview. “In the elderly, inability to fall asleep or stay asleep are common issues that are brought to a health care provider,” she said. Dr. D’Ambrosio said she was not surprised by the study findings “as elderly patients often have sleep issues and sometimes a well-meaning health care provider gives them sleep medication to help. We have known that some of these sleep medications such as benzodiazepines affect cognitive performance,” she said.
Dr. D’Ambrosio said she avoids prescribing sleep medications for older adults if possible. “A deep dive into sleep habits, environment, and other things that disrupt sleep often gets to the problem rather than just masking it with a sleep medication,” she noted. Alternatives to improve sleep in older adults include exercise, exposure to bright light during the day, and good healthy sleep habits, all of which contribute to improved sleep in the elderly, said Dr. D’Ambrosio. She also recommends screening older adults for other issues that affect sleep, such as chronic pain.
The current study highlighted the association between sleep medication use and dementia, but it does not show causation, Dr. D’Ambrosio said. “So much more needs to be done to determine whether the sleep medications are causing worsening cognitive function long term, or if the dementia is starting but not yet diagnosed and the sleep medication is given but not the cause of the dementia, she noted.
Research gaps and treatment strategies
Older adults experiencing sleep difficulties may try various medications including pharmacologics (e.g., benzodiazepines), over-the-counter agents, such as diphenhydramine or doxylamine preparations, and/or herbal and nutritional supplements such as valerian or melatonin, said Mary Jo S. Farmer, MD, FCCP, of the University of Massachusetts Medical School–Baystate, Springfield, in an interview. “However, sleep medications, particularly benzodiazepines, are strongly discouraged by major medical associations including the American Geriatrics Society in part because of the growing evidence that use of sleep medications is associated with cognitive impairment and decline,” she said.
The current study results contribute to previous work demonstrating that both pharmacologic and nonpharmacologic sleep medication, although commonly administered, is associated with subsequent adverse outcomes in older adults, Dr. Farmer said. This association sets the stage for creative and different solutions for addressing poor sleep among older adults, such as behavioral treatments including cognitive-behavioral therapy, she noted.
Dr. Farmer said, “Areas for future research include exploring the causal link between prescription and/or over-the-counter sleep medication use and incident dementia in a randomized controlled trial,” she added.
“Another interesting opportunity for future research is to explore the indications for sleep medications among older adults since it has been shown in the general population that sleep difficulties represent only 12% of the indication for sleep medication prescriptions,” Dr. Farmer noted. “Future research could examine the strength of the underlying motivation to use sleep medication even in light of suggested long-term effects, and the effectiveness of other measures to avoid or minimize sleep difficulties,” she said.
“My experience is that the majority of ambulatory patients recently seen in sleep clinic want to avoid long-term use of sleep medications and will ask what other measures can be tried to consistently achieve a good night’s sleep without medication use,” Dr. Farmer said. “If medications are used, patients would rather try melatonin than a benzodiazepine. Many patients who come to sleep clinic with sleep medications already prescribed and are subsequently found to have sleep apnea and/or restless legs find that they no longer need sleep medication when these other medical conditions are appropriately diagnosed and managed,” she explained. “Finally, many patients tell me they feel less energetic upon awakening, almost feel hung over, and express being less sharp cognitively when taking pharmacologic sleep medication, whether for short or long periods of time, and therefore they want to avoid continuing with sleep medication use,” she said.
Dr. Farmer’s strategy for developing alternatives to sleep medications in older adults includes taking a careful history, including a complete list of medical problems, review of medications, and a thorough sleep history including usual time of sleep onset, awake time, and the frequency of daytime naps. “Tips for improving the quality of nighttime sleep may include adequately treating pain and other medical conditions such as heartburn, sleep apnea, and restless legs, creating a soothing environment to promote sleep by eliminating noise and bright lights, avoiding stimulant medications and substances such as caffeine and nicotine before bedtime, avoiding excessive amounts of alcohol, avoiding diuretics before bedtime, encouraging physical activity during the day, spending time in the sunlight as much as possible to help regulate the sleep cycle, limiting daytime naps, and establishing a regular sleep schedule,” she said.
The study was supported by National Institutes of Health awards K01HL150339, U54MD000538, K07AG052685, R01AG056531, R01AG056031. Lead author Dr. Robbins had no financial conflicts to disclose.
