PFAS exposure in pregnancy tied to obesity risk in granddaughters

Article Type

Exposure during pregnancy to a specific per- and polyfluoroalkyl substance (PFAS), combined with a low cholesterol level, is linked to a heightened risk of abdominal and whole-body obesity in granddaughters, according to a new analysis of the Child Health and Development Studies, which have been ongoing since the 1960s.

Researchers directly measured levels of N-ethyl-perfluorooctane sulfonamido acetic acid (EtFOSAA) in blood samples from the grandmothers, which had been taken shortly after delivery, and then analyzed measures of obesity and other metabolic factors in their daughters at ages 30 years and 50 years, and their granddaughters at age 20.

PFASs are synthetic compounds commonly used as oil and water repellents; coatings for cookware, carpets, and textiles; and as firefighting foams. The compounds do not break down in the environment or the human body and accumulate over time. They are known to disrupt the endocrine system.

EtFOSAA is a metabolite of a raw material used in the manufacturing of packaging and paper products, and itself gets converted to perfluorooctane sulfonic acid (PFOS), which is extremely stable in the environment and within organisms, leading to bioaccumulation that has the potential to span generations, Barbara A. Cohn, PhD, director of child health and development studies at the Public Health Institute in Berkeley, Calif., said during a virtual press conference held by The Endocrine Society. The study was slated for presentation during ENDO 2020, the society’s annual meeting, which was canceled because of the COVID-19 pandemic.

Abdominal obesity was defined as a waist circumference of more than 34.6 inches (88 cm), and whole-body obesity was defined as a body mass index of more than 30 kg/m2. Findings from a previous study drawn from the same cohort showed that exposure to EtFOSAA, combined with high maternal cholesterol levels, was linked to increased risk of breast cancer in daughters.

“I want to emphasize that we don’t understand the mechanism, but we do know that this finding [from the current study], if it is confirmed, has implications for the current epidemic of obesity. Exposure to these compounds is very widespread, [having] started in the 1940s and 50s, and is consistent with the timing of the obesity epidemic,” said Dr. Cohn, during the virtual press conference.

Dr. Robert Sargis

Robert Sargis, MD, professor of endocrinology, diabetes, and metabolism at the University of Illinois at Chicago, said the mechanistic connection could be complex. “It’s a combination of the possibility that the chemicals themselves are passed down either through breast milk or across the placenta, or that the biological impact is somehow coded epigenetically, and then that epigenetic code is somehow passed on to subsequent generations,” he said in an interview. He was not associated with the research.

Dr. Cohn said her team is investigating both of those possibilities through analysis of the existing blood samples. “There are implications for PFAS clean-up if [these findings are] confirmed, and there’s an opportunity for setting up precautions for pregnant women on how they can try to avoid this contamination to [offset] a rekindling of this generational effect 60 years down the road,” Dr. Cohn added.

Daughters of the original participants (now grandmothers) were measured at an average age of 50, and the granddaughters, at an average of 20 (219 dyads, 657 women in total). Daughters also reported their weight at age 30, which was close to the mean age at which they had given birth. This allowed the researchers to control for obesity present during gestation of the granddaughters.

The researchers analyzed EtFOSAA, PFOS, and cholesterol levels from archived blood samples taken from grandmothers within 3 days of delivery. There was an association between EtFOSAA and self-reported obesity at age 30 in daughters, as well as measured abdominal, whole-body obesity, and blood pressure at age 20 in granddaughters, and all were modified by low cholesterol levels (25% interquartile) in grandmothers (P < .05).

In granddaughters, the combined risk of abdominal and whole-body obesity was 2.3-fold higher in those whose grandmothers were in the top 25% of EtFOSAA exposure, compared with those whose grandmothers were in the lowest 25% (95% confidence interval, 1.1-4.8). Those associations remained after adjustments for race, being overweight in early pregnancy (BMI, >25 kg/m2), and serum PFOS levels.

Although the weight of daughters did not affect the association between the granddaughters’ risk for obesity risk and EtFOSAA levels in grandmothers, it did predict high metabolic risk in granddaughters. That suggests that the burden may be building over generations. “Independently, their mothers themselves are heavier and fatter, and that heaviness of the mother is also a source of increasing body size for the granddaughter. We have a multiplying, very ugly situation that may be helping us to understand this really quick rise of obesity,” said Dr. Cohn.

She also emphasized that PFAS may not be the only culprit in fueling obesity. “Most of us believe that there is sufficient data in the animal studies and, now, growing data in human studies, to suggest that these obesogens exist and are contributing to the health problems that are going to be following the obesity epidemic in young people now.”

Dr. Cohn noted that the study is limited by its lack of a control group.

The California Breast Research Foundation, the National Institutes of Health, and the State of California funded the study. Dr. Cohn and Dr. Sargis reported no relevant financial disclosures.

The study abstract will be published in the Journal of the Endocrine Society. In addition to a series of news conferences held on March 30-31, the society will host ENDO Online 2020 during June 8-22 with programming for clinicians and researchers.

Barriers to clinical trial participation revealed by gynecologic cancer patients

Article Type
Changed

A survey of gynecologic cancer survivors has revealed why some of these patients don’t participate in clinical trials.

Half of survey respondents with no history of trial participation said their medical team never mentioned the possibility of a trial. About 27% of respondents who never enrolled in a trial said they were interested in trial participation but didn’t qualify, the trial they wanted wasn’t available, their insurance didn’t cover participation, or the trial site was too far away.

Annie Ellis and Mary (Dicey) Jackson Scroggins, who are both ovarian cancer survivors and patient advocates, reported these findings in an abstract that had been slated for presentation at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer. The meeting was canceled because of the COVID-19 pandemic.

Annie Ellis

“We thought it was important to hear and learn directly from gynecologic cancer survivors,” Ms. Ellis said in an interview. “So we decided to conduct a survey that would expand knowledge about clinical trial participation from a gynecologic cancer patient–specific perspective.”

Ms. Ellis and Ms. Scroggins used survivor networks and social media to distribute a 26-question survey on trial participation. The survey was completed by 189 survivors of gynecologic cancers, 49.19% of whom experienced recurrent disease. The most common diagnoses were ovarian cancer (69.84%) and endometrial or uterine cancer (23.28%).
 

Perspectives of nonparticipants

Most respondents (65.61%) had never participated in a clinical trial. The most common reason was that the patient’s doctor or medical team never discussed trial participation (50.40%).

There were patients who were interested in trial participation but couldn’t enroll because they didn’t qualify (14.40%), the location was too far away (7.20%), the trial they wanted wasn’t available (4.00%), or their insurance didn’t cover trial participation (1.60%).

Patients who were not interested in trial participation said they didn’t want to receive a placebo (11.20%), they weren’t interested in experimental therapies (3.20%), or they didn’t want to be randomized (2.40%). One patient (1.60%) said she does not trust the medical system.

“Given the frequent conversations about distrust in the medical system, we were surprised that only 1 of the 189 respondents indicated distrust in the medical system as a reason for not participating in a clinical trial,” Ms. Ellis said.
 

Perspectives of trial participants

Mary (Dicey) Jackson Scroggins

Roughly a third of respondents (34.39%) had participated in a clinical trial. Most (86.15%) said they learned about the trial from their doctor. Other sources included the patient’s own research (13.85%), a trial matching service (3.08%), a family member or friend (3.08%), and a support group (1.54%).

The most common reasons patients participated in trials were: “my doctor recommended it,” “to help women in the future,” “to expand my treatment options,” and “to have a chance to benefit personally.”

Additional responses indicated that patients viewed their trial participation in a positive light.

“We were surprised to find that 100% of the respondents who had participated in a clinical trial indicated either that they would participate again (84.62%) or that they were not sure about future participation (15.38%),” Ms. Ellis said. “No respondent indicated that she would not consider another trial. From open comments in the survey, it was clear that even if they did not obtain the result they hoped for or if the experience wasn’t optimal, they maintained the option of participating again.”
 

 

 

Implications and next steps

The survey results suggest there is a need for more discussions about clinical trials with patients who have gynecologic cancers, according to Ms. Ellis and Ms. Scroggins.

“We feel that conversations about clinical trials, with health care team members, should be included at every care decision point, even if – or perhaps especially if – the patient belongs to a group perceived to be unlikely to agree to participate in a trial,” Ms. Ellis said.

“These conversations are necessary with all patients-survivors,” she said, “but they are particularly important and necessary with patients from populations underrepresented in the clinical trial system if we want more representative trial populations, more generalizable results, and the potential for better outcomes for all.”

For their part, Ms. Ellis and Ms. Scroggins plan to conduct more research on this topic to gain additional insights.

“We’d like to conduct a larger survey looking deeper into barriers to and reasons for participation, and to work with medical professionals to develop models of communication to encourage consideration of clinical trials,” Ms. Ellis said. “Additionally, we will work to have a more diverse respondent pool across many dimensions.”

Ms. Ellis is a research advocate on the scientific advisory committee of the Ovarian Cancer National Alliance in Washington. Ms. Scroggins is the director of global outreach and engagement at the International Gynecologic Cancer Society in Louisville, Ken. They have no conflicts of interest.

Pembrolizumab Plus Neoadjuvant Chemotherapy Improves Pathologic Complete Response Rates in Triple-Negative Breast Cancer

Study Overview

Objective. To evaluate the efficacy and safety of pembrolizumab in combination with neoadjuvant chemotherapy followed by adjuvant pembrolizumab in early-stage triple-negative breast cancer.

Design. International, multicenter, randomized, double-blind, phase 3 trial.

Intervention. Patients were randomly assigned in a 2:1 fashion to receive either pembrolizumab or placebo. Patients received 4 cycles of neoadjuvant pembrolizumab or placebo once every 3 weeks, in addition to weekly paclitaxel 80 mg/m2 plus carboplatin AUC5 once every 3 weeks. This was followed by 4 cycles of pembrolizumab or placebo plus doxorubicin 60 mg/m2 or epirubicin 90 mg/m2 plus cyclophosphamide 600 mg/m2 once every 3 weeks. Patients then underwent definitive surgery 3 to 6 weeks after completion of neoadjuvant therapy. In the adjuvant setting, patients received pembrolizumab or placebo once every 3 weeks for up to 9 cycles. Adjuvant capecitabine was not allowed.

Setting and participants. A total of 1174 patients underwent randomization: 784 patients in the pembrolizumab/chemotherapy group and 390 patients in the placebo/chemotherapy group. Eligible patients had newly diagnosed, centrally confirmed triple-negative breast cancer (nonmetastatic: T1c, N1-2 or T2-4, N0-2). Patients were eligible regardless of PD-L1 status, and those with inflammatory breast cancer and multifocal primaries were eligible.

Main outcome measures. The primary endpoints of this study were pathologic complete response (pCR) rate (defined as ypT0/ypTis, ypN0) at the time of surgery and event-free survival (EFS) in the intention-to-treat population. Secondary endpoints included pCR in all patients, pCR among patients with PD-L1–positive tumors, EFS among patients with PD-L1–positive tumors, and overall survival among all patients and those with PD-L1–positive tumors. PD-L1 expression was assessed using the PD-L1 IHC 22C3 pharmDx assay (Agilent, Santa Clara, CA). Expression was characterized according to the combined positive score, with a score of 1% or greater being considered positive.

Results. The baseline characteristics were well balanced between the treatment arms. At the time of the second interim analysis, the median duration of follow-up was 15.5 months. The pCR rate among the first 602 patients who were randomized was 64.8% in the pembrolizumab/chemotherapy group and 51.2% in the placebo group (P < 0.001; 95% confidence interval, 5.4-21.8). The pCR rate in the PD-L1–positive population was 68.9% in the pembrolizumab/chemotherapy group, as compared to 54.9% in the placebo group. In the PD-L1–negative population, the pCR rate was 45.3% in the pembrolizumab/chemotherapy group, as compared to 30.3% in the placebo group. At the time of analysis, 104 events had occurred, and the estimated percentage of patients at 18 months who were alive without disease progression was 91% in the pembrolizumab group and 85% in the placebo group. The median was not reached in either group.

Grade 3 or higher adverse events in the neoadjuvant phase were seen in 76.8% and 72.2% of patients in the pembrolizumab and placebo arms, respectively. Serious treatment-related adverse events occurred in 32% of patients in the pembrolizumab group compared to 19% in the placebo group. Febrile neutropenia and anemia were the most common. Discontinuation of the trial drug due to adverse events occurred in 23% of patients in the pembrolizumab arm and in 12% in the placebo arm. The majority of treatment-related adverse events occurred in the neoadjuvant phase. In the adjuvant phase, treatment-related adverse events occurred in 48% and 43% of patients in the pembrolizumab and placebo groups, respectively.

 

 

Conclusion. The combination of neoadjuvant chemotherapy and pembrolizumab in patients with newly diagnosed, early-stage, triple-negative breast cancer yielded a higher percentage of patients achieving a pCR as compared with chemotherapy plus placebo.

Commentary

The current study adds to the growing body of literature outlining the efficacy of immune checkpoint inhibition in triple-negative breast cancer. The previously published IMpassion130 trial showed that the addition of the PD-L1 antibody atezolizumab to nab-paclitaxel improved progression-free survival in patients with PD-L1–positive (1% or greater), metastatic triple-negative breast cancer.1 Similarly, in the phase 2 I-SPY2 trial, the addition of pembrolizumab to standard neoadjuvant chemotherapy led to a near tripling of the pCR rates in triple-negative breast cancer.2 While the current study demonstrated improved pCR rates with pembrolizumab, no difference in EFS has yet been demonstrated; however, longer-term follow-up will be required. There certainly are numerous studies documenting an association between pCR and improved disease-free survival and possibly overall survival. Cortazar and colleagues performed a pooled analysis of 12 international trials, which demonstrated an association between pCR and improved EFS (hazard ratio [HR], 0.24) and overall survival (HR, 0.16) in patients with triple-negative breast cancer.3 The results of the current study will require longer-term follow-up to confirm such an association.

The current study appears to have demonstrated a benefit with the addition of pembrolizumab across treatment subgroups, particularly in the PD-L1–positive and PD-L1–negative populations. While this differs from the findings of the IMpassion130 trial, it is quite difficult to draw definitive conclusions because the 2 trials studied different antibodies, and thus used a different assay to define PD-L1 positivity. Notable differences exist in determination of PD-L1 status across assays, and it is important for providers to use the appropriate assay for each antibody. These differences highlight the need for more informative biomarkers to predict a benefit from immune checkpoint inhibition.

It is also noteworthy that the control arm in the current trial was a platinum-based regimen. Platinum-based neoadjuvant regimens previously have been shown to induce higher pCR rates in triple-negative breast cancer; however, the incorporation of carboplatin as standard of care remains a topic of debate.4 Nevertheless, a similar trial evaluating the efficacy of atezolizumab combined with platinum-based neoadjuvant chemotherapy in triple-negative breast cancer, NSABP B-59 (NCT03281954), is underway, with the control arm also incorporating carboplatin. The results of this study will also help validate the role of checkpoint inhibitors in the neoadjuvant setting in triple-negative breast cancer. Of note, this trial did not allow for the use of adjuvant capecitabine, which has been previously shown in the CREATE-X trial to prolong survival in this population.5 How the use of adjuvant capecitabine would impact these results is completely unknown.6 The incidence of grade 3 or higher toxicities in the current trial appeared to be similar in both groups. There did appear to be a higher incidence of infusion reactions and skin reactions in the pembrolizumab groups. Immune-related adverse events were consistent with prior pembrolizumab data.

Applications for Clinical Practice

KEYNOTE-522 adds to the growing evidence suggesting that incorporation of immune checkpoint inhibitors into neoadjuvant therapy in patients with triple-negative breast cancer can improve pCR rates; however, its use as a standard of care will require longer-term follow-up to ensure the noted findings translate into improvement in EFS and, ultimately, overall survival.

Study Overview

Objective. To evaluate the efficacy and safety of pembrolizumab in combination with neoadjuvant chemotherapy followed by adjuvant pembrolizumab in early-stage triple-negative breast cancer.

Design. International, multicenter, randomized, double-blind, phase 3 trial.

Intervention. Patients were randomly assigned in a 2:1 fashion to receive either pembrolizumab or placebo. Patients received 4 cycles of neoadjuvant pembrolizumab or placebo once every 3 weeks, in addition to weekly paclitaxel 80 mg/m2 plus carboplatin AUC5 once every 3 weeks. This was followed by 4 cycles of pembrolizumab or placebo plus doxorubicin 60 mg/m2 or epirubicin 90 mg/m2 plus cyclophosphamide 600 mg/m2 once every 3 weeks. Patients then underwent definitive surgery 3 to 6 weeks after completion of neoadjuvant therapy. In the adjuvant setting, patients received pembrolizumab or placebo once every 3 weeks for up to 9 cycles. Adjuvant capecitabine was not allowed.

The pCR rate in the PD-L1–positive population was 68.9% in the pembrolizumab/chemotherapy group, as compared to 54.9% in the placebo group. In the PD-L1–negative population, the pCR rate was 45.3% in the pembrolizumab/chemotherapy group, as compared to 30.3% in the placebo group. At the time of analysis, 104 events had occurred, and the estimated percentage of patients at 18 months who were alive without disease progression was 91% in the pembrolizumab group and 85% in the placebo group.

Novel drugs approved in 2019

Article Type
Changed

In 2019, the Food and Drug Administration approved 42 drugs, 6 of which will not be discussed here because of space limitations: recarbrio, a three-drug combination, containing imipenem, cilastatin, and relebactam; polatuzumab (Polivy) combined with bendamustine and a rituximab product; pretomanid combined with bedaquiline and linezolid; romosozumab (Evenity) for postmenopausal women; and alpelisib (Piqray) for postmenopausal women. In addition, darolutamide (Nubeqa) will not be included because it is indicated for the treatment of patients with prostate cancer. The remaining 36 agents are listed alphabetically below with the trade names in parentheses.

PhotoDisk

The molecular weights (if available), rounded to the nearest whole number, are shown in parentheses. As with nearly all drugs, avoiding these agents in pregnancy is the best choice.

Air polymer-type a intrauterine foam (ExEm Foam), an ultrasound contrast agent, is indicated for sonohysterosalpingography to assess fallopian tube patency in women with known or suspected infertility. Animal studies have not been conducted, and the agent is contraindicated in pregnancy.

Afamelanotide implant (Scenesse) (1,647) is a melanocortin 1 receptor agonist that is indicated to increase pain-free light exposure in adult patients with a history of phototoxic reactions from erythropoietic protoporphyria. The drug caused no embryofetal toxicity in two species of rats. The molecular weight suggests that it will not cross the placenta, at least early in pregnancy.

Alpelisib (Piqray) (441) is a kinase inhibitor that is combined with fulvestrant for the treatment of advanced breast cancer in women and men. The molecular weight suggests that it can cross the human placenta. It is contraindicated in pregnancy because it can cause embryofetal toxicity.

Bremelanotide (Vyleesi) (1,025) is indicated for the treatment of premenopausal women with hypoactive sexual disorder. The drug caused fetal harm in dogs and mice. If a pregnant woman is exposed to the drug, health care providers are encouraged to call the VYLEESI Pregnancy Exposure Registry at 877-411-2510.

Brolucizumab (Beovu) (26,000) is a human vascular endothelial growth factor that is indicated for the treatment of neovascular age-related macular degeneration. In animals, it caused malformations, embryofetal resorption, and decreased fetal weight. Other adverse effects were follicular development, corpus luteum function, and fertility.

Caplacizumab (Cablivi) (28,000) is indicated for the treatment of adult patients with acquired thrombotic thrombocytopenia purpura, in combination with plasma exchange and immunosuppressive therapy. If used in pregnancy, there is a risk of hemorrhage in the mother and fetus. In guinea pigs given intramuscular doses of the drug, there was no evidence of adverse developmental outcomes.

Cefiderocol (Fetroja) (3,044) is an IV cephalosporin antibiotic indicated for the treatment of urinary tract infections, including pyelonephritis. The manufacturer states that it should be used in patients 18 years of age or older who have limited or no alternative treatment options. Consistent with other cephalosporins, no developmental adverse effects were observed in rats and mice.

Cenobamate (Xcopri) (268) is indicated for the treatment of partial-onset seizures in adults. In pregnant animals given the drug, there was increased embryo-fetal mortality, decreased fetal and offspring body weight, and neurobehavioral and reproductive impairment in offspring. If a pregnant woman receives this drug, encourage her to enroll in the North American Antiepileptic Drug Pregnancy Registry by calling the toll-free number 1-888-233-2334.

Crizanlizumab (Adakveo) (146,000) is indicated to reduce the frequency of vaso-occlusive crises in patients with sickle cell disease. In monkeys given doses slightly higher than those given to humans, there was increased fetal loss (abortions/stillbirths).

Entrectinib (Rozlytrek) (561) is a kinase inhibitor indicated for the treatment of cancer. The drug was teratogenic in rats. It is contraindicated in pregnancy because it can cause embryo-fetal toxicity.

Erdafitinib (Balversa) (447), a kinase inhibitor, is indicated for the treatment of locally advanced or metastatic urothelial carcinoma. In rats given doses during organogenesis with maternal exposures less than human exposures, the drug was teratogenic and caused embryofetal death. The manufacturer states that women of reproductive potential should use effective contraception during treatment and for 1 month after the last dose. The same advice was provided for male patients with female partners of reproductive potential. It is contraindicated in pregnancy because it can cause embryofetal toxicity.

Fedratinib (Inrebic) (616), a kinase inhibitor, is indicated for patients with intermediate-2 or high-risk primary or secondary myelofibrosis. The drug was teratogenic in rats when doses that were about 0.1 times the human exposure based on AUC (area under the curve) at the recommended daily dose during organogenesis. It is contraindicated in pregnancy because it can cause embryofetal toxicity.

Fluorodopa f18 (214) is a radioactive diagnostic agent.

Brexanolone (Zulresso) (319) is indicated for the treatment of postpartum depression. It is given as a continuous IV infusion over 60 hours. The drug, at exposures close to those seen in humans, did not cause structural defects in rabbits and rats, but did cause fetal toxicity. Because patients are at risk of excessive sedation or sudden loss of consciousness when receiving the drug, it is only available through a restricted program called the ZULRESSO REMS. Health care providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 844-405-6185. To obtain a list of health care facilities enrolled in the program call 844-472-4379.

Nearly all of the above drugs will cross into a woman’s colostrum during the first 48 hours post partum. These amounts should be very small, but not breastfeeding is the best choice.

Voxelotor (Oxbryta) (337) is an oral hemoglobin S polymerization inhibitor indicated for the treatment of sickle cell disease. In rats and rabbits, there was no evidence of adverse developmental outcomes.

Zanubrutinib (Brukinsa) (472), an oral kinase inhibitor, is indicated for the treatment of mantle cell lymphoma. The drug caused embryofetal toxicity in pregnant rats, including malformations. It is contraindicated in pregnancy because it can cause embryo-fetal toxicity.

Brexanolone (Zulresso) (319) is indicated for the treatment of postpartum depression. It is given as a continuous IV infusion over 60 hours. The drug, at exposures close to those seen in humans, did not cause structural defects in rabbits and rats, but did cause fetal toxicity. Because patients are at risk of excessive sedation or sudden loss of consciousness when receiving the drug, it is only available through a restricted program called the ZULRESSO REMS. Health care providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 844-405-6185. To obtain a list of health care facilities enrolled in the program call 844-472-4379.

Nearly all of the above drugs will cross into a woman’s colostrum during the first 48 hours post partum. These amounts should be very small, but not breastfeeding is the best choice.

Study challenges role of birth canal exposure in newborn microbiome establishment

Article Type
Changed

During parturient transmission of gut bacteria from mothers to infants, the dominant maternal source of bacteria is rectal, according to investigators.

This challenges the hypothesis that exposure to the birth canal explains major differences in gut bacteria between infants born vaginally and those born via C-section, reported Moran Yassour, PhD, of Hebrew University in Jerusalem.

“It’s not how and if you entered the birth canal, but rather how you exited it,” Dr. Yassour said during a presentation at the annual Gut Microbiota for Health World Summit.

According to Dr. Yassour, a number of investigators have evaluated vertical transmission of gut bacteria from mothers to newborns, but most began collecting data a week or more after birth, potentially missing critical information.

“We wanted to generate large-scale, paired, longitudinal data, which means that we had [samples from] both mothers and children, and we wanted to start at birth,” Dr. Yassour said at the meeting, sponsored by the American Gastroenterological Association and the European Society for Neurogastroenterology and Motility.

Dr. Yassour explained that newborns delivered vaginally often exhibit Bacteroides in their gut, whereas babies born via C-section do not exhibit these bacteria until 6-18 months of age; however, the vaginal microbiome typically lacks Bacteroides, making the birth canal an unlikely source. This disconnect served as the impetus for the present investigation, Dr. Yassour said.

The study, which is available as a preprint, involved 73 mothers and their infants. To determine the impact of birth canal exposure, the investigators compared gut bacteria of infants born vaginally with those born via pre-labor C-section (no exposure to the birth canal), and those born via post-labor C-section (exposure to the birth canal).

Initial results were surprising, Dr. Yassour said, as 54% of babies delivered via C-section had Bacteroides in their stool during the first week. But in the second week, 94% of the C-section group lacked Bacteroides, which aligns with characteristic findings and suggests failure of colonization, rather than complete lack of exposure.

Out of the 24 infants with persistent Bacteroides colonization, 22 (92%) were born vaginally, compared with 2 (8%) born via pre-labor C-section, and none born via post-labor C-section. This pattern was maintained in a multivariate analysis that accounted for antibiotic use and exposure to formula, both of which are more common among mothers that give birth via C-section.

The investigators also conducted a strain-level analysis of mothers and infants using metagenomic sequencing. Across all time points, 90% of matched maternal-infant strains were detected in babies delivered vaginally.

“[W]e found evidence for mother-to-child transmission of rectal rather than vaginal strains,” the investigators wrote. “These results challenge birth canal exposure as the dominant factor in infant gut microbiome establishment and implicate colonization efficiency rather than exposure as a dictating factor of the newborn gut microbiome composition.”

Dr. Yassour said that these findings may have an immediate effect on clinical practice.

“People have reported the practice of smearing babies that were born by C-section with vaginal fluids in the sense of trying to recapitulate the microbial signature that we find in kids born vaginally,” Dr. Yassour said. “But it’s probably not the vaginal fluid that we need to smear; it’s probably the proximity to the rectum and the bowel movements that happen during delivery ... and that is what’s causing this initial seeding from mother to child.”

Dr. Yassour disclosed no conflicts of interest.

HCV screening risk factors in pregnant women need updating

Article Type
Changed

Current risk factors used to screen for hepatitis C should be updated, according to study results of 106,842 pregnant women who underwent screening.

“Because risk-factor screening has obvious limitations, universal screening in pregnancy has been suggested to allow for linkage to postpartum care and identification of children for future testing and treatment,” wrote Mona Prasad, DO, of Ohio State University, Columbus, and colleagues.

In a study published in Obstetrics & Gynecology, the researchers reviewed data from women with singleton pregnancies presenting for prenatal care prior to 23 weeks’ gestation during 2012-2015. Of these, 254 tested positive for the hepatitis C virus (HCV) antibody, for a seroprevalence rate of 2.4 cases per 1,000 women.

The researchers conducted a case-control analysis of 131 women who tested positive and 251 controls to identify HCV infection risk factors based on interviews and chart reviews. They found that risk factors significantly associated with positive HCV antibodies included injection drug use (adjusted odds ratio, 22.9), a history of blood transfusion (aOR, 3.7), having an HCV-infected partner (aOR, 6.3), having had more than three sexual partners (aOR, 5.3), and smoking during pregnancy (aOR, 2.4).

In an unadjusted analysis, the researchers confirmed two of the risk factors currently recommended by the Centers for Disease Control and Prevention for screening for HCV: injection drug use and being born to a mother with HCV infection, but not dialysis, organ transplantation, or HIV infection.

“Our results demonstrate that current risk factors could be contemporized,” Dr. Prasad and colleagues noted. “The currently accepted risk factors such as exposure to clotting factors, dialysis, and organ transplants are unlikely to be found. A thorough assessment of injection drug use history, smoking, transfusions, number of sexual partners, and partners with HCV infection is more sensitive in an obstetric population.”

The study findings were limited by several factors including possible selection bias and inclusion of only 65% of eligible women who were HCV positive, as well as a lack of screening data from 2016 to the present, which may not reflect the impact of the recent opioid epidemic, the researchers noted. However, the results were strengthened by the large sample size, and the generalizability of the study population.

“Our results regarding prevalence rates and risk factors of HCV antibody among pregnant women in the United States will be valuable to policymakers as they weigh the costs and benefits of universal screening,” Dr. Prasad and associates concluded.

Although universal screening has the potential to be more cost effective, given the small population of pregnant women eligible for treatment and lack of an available treatment, “the rationale is weaker for unique universal HCV screening recommendations for pregnant women,” they said.

By contrast, Sammy Saab, MD, MPH, of the University of California, Los Angeles; Ravina Kullar, PharmD, MPH, of Gilead Sciences, Foster City, Calif.; and Prabhu Gounder, MD, MPH, of the Los Angeles Department of Public Health, wrote an accompanying commentary in favor of universal HCV screening for pregnant women, in part because of the increase in HCV in the younger population overall.

“For many women of reproductive age, pregnancy is one of their few points of contact with their health care provider; therefore, pregnancy could provide a crucial time for targeting this population,” they noted.

Risk-based screening is of limited effectiveness because patients are not identified by way of current screening tools or they decline to reveal risk factors that providers might miss, the editorialists said. Pregnancy has not been shown to affect the accuracy of HCV tests, and identifying infections in mothers allows for screening in children as well.

“The perinatal hepatitis B virus infection program, which has been implemented in several state and local public health departments, could serve as an example for how to conduct surveillance for mothers with HCV infection and to ensure that HCV-exposed children receive appropriate follow-up testing and linkage to care,” the editorialists concluded.

The study was supported in part by multiple grants from the National Institute of Child Health and Human Development. Dr. Prasad disclosed funding from Ohio State University and from Gilead. Coauthors had links with pharmaceutical companies, associations, and organizations – most unrelated to this study. The editorialists had no financial conflicts to disclose.

Focus groups seek transgender experience with HIV prevention

Article Type
Changed

A pair of focus groups explored the experience of transgender patients with HIV prevention, finding many were discouraged by experiences of care that was not culturally competent and affirming.

The findings, including other important themes, were published in Pediatrics.

The pair of online asynchronous focus groups, conducted by Holly B. Fontenot, PhD, RN/NP, of the Fenway Institute in Boston, and colleagues, sought input from 30 transgender participants from across the United States. Eleven were aged 13-18 years, and 19 were aged 18-24 years, with an average age of 19. Most (70%) were white, and the remainder were African American (7%), Asian American (3%), multiracial (17%), and other (3%); 10% identified as Hispanic. Participants were given multiple options for reporting gender identity; 27% reported identifying as transgender males, 17% reported identifying as transgender females, and the rest identified with other terms, including 27% using one or more terms.

The quantitative analysis found four common themes, which the study explored in depth: “barriers to self-efficacy in sexual decision making; safety concerns, fear, and other challenges in forming romantic and/or sexual relationships; need for support and education; and desire for affirmative and culturally competent experiences and interactions.”

Based on their findings, the authors suggested ways of improving transgender youth experiences:

  • Increasing provider knowledge and skills in providing affirming care through transgender health education programs.
  • Addressing the barriers, such as stigma and lack of accessibility.
  • Expanding sexual health education to be more inclusive regarding gender identities, sexual orientations, and definitions of sex.

Providers also need to include information on sexually transmitted infection and HIV prevention, including “discussion of safer sexual behaviors, negotiation and consent, sexual and physical assault, condoms, lubrication, STI and HIV testing, human papillomavirus vaccination, and PrEP [preexposure prophylaxis]” the authors emphasized.

Dr. Fontenot and associates determined that this study’s findings were consistent with what’s known about adult transgender patients, but this study provides more context regarding transgender youth experiences.

“It is important to elicit transgender youth experiences and perspectives related to HIV risk and preventive services,” they concluded. “This study provided a greater understanding of barriers to and facilitators of youth obtaining HIV preventive services and sexual health education.”

Limitations of the study included that non–English speaking participants were excluded, and that participants were predominantly white, non-Hispanic, and assigned female sex at birth.

This study was funded by the Centers for Disease Control and Prevention and NORC at The University of Chicago. The authors had no relevant financial disclosures.

Cervical pessary didn’t prevent preterm birth in selected women

Among women with twin pregnancy and a short cervix, the Arabin cervical pessary did not significantly affect the likelihood of preterm birth or a composite measure of adverse neonatal outcomes, according to a randomized, open-label study.

“The Arabin pessary should not be used to prevent preterm birth in women with twin pregnancy,” Jane E. Norman, MD, dean of health sciences at the University of Bristol (England), said at the Pregnancy Meeting.

“Preterm birth is very common in twin pregnancy” and leads to “excess neonatal mortality amongst twins,” Dr. Norman said at the meeting, which is sponsored by the Society for Maternal-Fetal Medicine. “Preventing preterm birth is important for both singletons and twins, but it could have even more benefits in twins.”

Emerging evidence has suggested that the Arabin cervical pessary may be useful for the prevention of preterm birth in women with singleton pregnancy and a short cervix. In twin pregnancy, data are more limited.

The ProTwin study randomized 813 women with twin pregnancy to a cervical pessary or standard care. Although the pessary had no impact on preterm birth overall, among women with cervical length of less than 38 mm, those who received a pessary were less likely to have preterm birth. The sample size was small, however, and the average length of the cervix in ProTwin differed from that in a previous U.K. study, Dr. Norman said.

Inspired by the study, Dr. Norman and coinvestigators conducted STOPPIT-2, a multicenter, open-label, randomized, controlled trial to further study whether a certain cervical length threshold was associated with benefit of a cervical pessary in preventing preterm birth. The trial included women with twin pregnancy who had a cervical length ultrasound between 18 and 20 weeks and 6 days of gestation. Women with a cervical length of 35 mm or less were eligible for randomization. Patients received an Arabin pessary plus standard care or standard care alone.

The primary obstetric outcome was spontaneous onset of labor leading to delivery before 34 weeks and 6 days of gestation. The primary neonatal outcome was a composite of outcomes – stillbirth, neonatal death, periventricular leukomalacia, respiratory morbidity, intraventricular hemorrhage, necrotizing enterocolitis, or sepsis – measured up to 28 days after the expected date of delivery.

The investigators randomized 503 women in all, including 250 to the pessary and 253 to standard care. Both groups had similar baseline characteristics, Dr. Norman said. The average age was about 33 years, and the average cervical length was about 29 mm. A total of 20% had monochorionic diamniotic pregnancies, and 80% had dichorionic pregnancies. The researchers excluded women with monochorionic monoamniotic pregnancies. In the pessary group, 16 patients declined the intervention, and 4 were unable to have the pessary inserted.

Spontaneous preterm birth occurred in 18% of patients in the Arabin pessary group, compared with 21% in the standard treatment group. The adjusted odds ratio, 0.87, was not statistically significant. In subgroups of patients with monochorionic pregnancy, cervical length less than 28 mm, or cervical length less than 25 mm, there was no significant benefit.

The composite measure of adverse neonatal outcomes also did not significantly differ between the groups. None of the individual components indicated benefit of the pessary either, Dr. Norman said.

In subgroup analyses, odds ratios for adverse neonatal outcomes were “tending towards harm for the Arabin pessary group ... although clearly none of them conferring statistical significance,” she said. Among women with cervical length less than 28 mm, a primary neonatal outcome – at least one of the adverse outcomes – occurred in 23% of patients in the Arabin pessary group, compared with 20% of patients in the standard care group.

Approximately two-thirds of patients found pessary insertion painless or slightly uncomfortable, whereas about 10% described the experience of device fitting as very uncomfortable, and about 1% described it as the worse pain imaginable.

“Since we started STOPPIT-2, in addition to ProTwin, another three studies have been published on the efficacy of the Arabin pessary in twins,” said Dr. Norman. Combined data show no significant effect of the pessary on preventing preterm birth in twin pregnancy. Still, the meta-analysis does not rule out the possibility that there could subgroups of patients who may benefit from the intervention, Dr. Norman said.

STOPPIT-2 was funded by the National Institute for Health Research (NIHR) in the United Kingdom. Dr. Norman chaired the UK National Institute for Health and Care Excellence guidelines on preterm labor and birth in 2015. In addition, Dr. Norman was a member of a GlaxoSmithKline data safety and monitoring group for a trial of a preterm birth prevention agent, has consulted for Dilafor, and has received research grants for preterm birth prevention from the U.K. Medical Research Council, NIHR, and Tommy’s: Together, for every baby charity.

Maternal methadone opioid maintenance therapy may be tied to smaller postnatal head circumference

Opioid maintenance therapy with methadone during pregnancy may be associated with a significantly smaller postnatal head circumference percentile, compared with opioid maintenance therapy with buprenorphine, according to a study presented at the Pregnancy Meeting.

Antenatal ultrasound measurements do not differ by treatment, however, the researchers said. A separate study suggests that serial ultrasound examinations of fetal brain and biometry measurements may not be helpful in patients who receive these medications for opioid use disorder.

To examine the effects of methadone and buprenorphine opioid maintenance therapy on prenatal and postnatal growth parameters, Jay Davis, MD, a maternal-fetal medicine fellow at Stony Brook University in New York, and coinvestigators conducted a retrospective cohort study using medical records from an academic center during 2007-2017. They included women with singleton pregnancies receiving opioid maintenance therapy with methadone or buprenorphine. They compared head circumference percentile, abdominal circumference percentile, head circumference/abdominal circumference ratio, and postnatal head circumference percentile between the two groups. The investigators analyzed the data using the Wilcoxon–Mann–Whitney test, chi-square test, and logistic regression.

The researchers studied 282 cases, including 120 patients who received buprenorphine and 162 who received methadone. Patients who received buprenorphine delivered at a later average gestational age (39 weeks vs. 37.8 weeks) and had newborns with greater average birth weights (3,206 g vs. 2,877 g). Compared with patients who received methadone, patients who received buprenorphine were significantly more likely to have a larger postnatal head circumference percentile (39 vs. 30), Dr. Davis and colleagues reported. This difference remained significant after controlling for race, prescriber, gestational age at delivery, and birth weight.

In a separate study presented at the meeting sponsored by the Society for Maternal-Fetal Medicine, Jose M. Perez Yordan, MD, of the University of New Mexico, Albuquerque, and colleagues examined effects of medications for opioid use disorder on fetal brain and body measurements.

They found that maternal medications for opioid use disorder do not have a clinically significant effect on fetal brain and body measurements, compared with controls. “No consistent pattern of decreased fetal growth was identified, since the body measurement affected did not persist with serial ultrasounds,” they said. “Serial ultrasound examinations do not appear to be helpful in patients” who take medications of opioid use disorder, with or without alcohol coexposure, unless other risk factors are present.

To evaluate the effects of medications of opioid use disorder and alcohol coexposure on fetal brain and biometric measurements at the second- and third-trimester ultrasound measurements, the investigators are conducting a prospective study known as ENRICH-1. The study includes healthy controls, patients taking medications of opioid use disorder (that is, buprenorphine or methadone), and patients taking medications of opioid use disorder with alcohol coexposure.

Ultrasound measurements from the second and third trimesters evaluated biparietal diameter, femur length, frontal lobe width and length, front-thalamic distance, and caval-calvarial distance. Univariate and multivariate analyses assessed differences in measurements adjusting for gestational age and other factors.

The present analysis included data from 171 participants, including 56 healthy controls, 75 patients taking medications of opioid use disorder, and 40 patients taking medications of opioid use disorder with alcohol coexposure. There was no consistent pattern of decreased fetal growth. Affected measurements did not persist over time.

The study presented by Dr. Perez Yordan was supported by a National Institute on Alcohol Abuse and Alcoholism grant. The remaining investigators in both studies had no relevant financial disclosures.

CVH in pregnant women: Ample room for improvement

Article Type
Changed

Cardiovascular disease is both common and chronic, and it remains the leading cause of death in women. Because it is a life-long condition, cardiovascular disease must be managed over the entire lifespan. In recognition of the important role of obstetricians and gynecologists in monitoring women’s health, the American Heart Association/American College of Obstetricians and Gynecologists 2018 guidelines1 promoted the use of “Life’s Simple 7”2 for assessing cardiovascular health (CVH) in women.

These seven metrics include diet, physical activity, smoking status, body mass index (BMI), blood pressure, total cholesterol, and fasting blood glucose levels. They have been shown to predict positive health outcomes in nonpregnant adults. However, until now, CVH had not been assessed in pregnant women.

Perak et al. recently performed the first cross-sectional study of the prevalence of CVH metrics in pregnant women using the AHA definition.3 Using data from the National Health and Nutrition Examination Surveys (NHANES), they used the Life’s Simple 7 metrics to assess CVH in 1,117 pregnant and 8,200 nonpregnant women in the United States aged 20-44 years. Each of the Life’s Simple 7 metrics was scored 0, 1, or 2 points, corresponding to a rating of poor, intermediate, or ideal, respectively. Thus, the total CVH score ranged from 0-14 points, with total scores of 0-7 indicating low CVH, 8-11 indicating moderate CVH, and 12-14 indicating high CVH.

The main study findings were that CVH in pregnant women in the United States was far from optimal, with only 5% having an ideal score, which was even worse than in nonpregnant women, of whom only 13% were scored as having ideal CVH. Ideal scores were observed for 0.1% of pregnant women for diet, 27% for physical activity, 39% for cholesterol levels, 51% for BMI, 78% for smoking, 90% for blood pressure, and 92% for fasting blood glucose. Physical activity and cholesterol levels appeared to be the major drivers of the lower CVH scores in pregnant women.

Dr. Charles Wong

Although further studies are warranted to determine the relevance of CVH during pregnancy to outcomes for both mother and offspring, the study by Perak et al. is an important step toward the development of pregnancy-specific guidelines and definitions for CVH metrics. These are stated goals of the AHA/ACOG that will help promote CVH in women across their lifespans, but which have not been possible due to scant data.

Emerging data suggest that cumulative lifetime exposure is a significant factor in cardiovascular disease outcomes; therefore, earlier intervention would have a more significant impact. Just as gestational diabetes is a predictor of future type 2 diabetes, CVH earlier in a woman’s life predicts cardiovascular disease later in life.4-7 The best data in this regard come from genetic and other studies of hyperlipidemia, which suggest that lowering lipid levels before symptoms develop may prevent cardiovascular disease. In contrast, treatment of patients with clinically manifest disease neither offers a cure nor prevents the occurrence of most cardiovascular events.

It is a particularly salient point in this regard that there currently are no guidelines on treatment of hypercholesterolemia during pregnancy. Notably, the study by Perak et al. suggested that cholesterol levels may have a significant impact on CVH in pregnant women. There also is emerging data supporting the importance of controlling blood pressure across the lifespan,7,8 including during pregnancy.9

Dr. E. Albert Reece

For many women, their ob.gyn. is their primary care physician, and pregnancy is often the first time that a woman will have a substantial interaction with the health care system. The AHA/ACOG advisory panel described pregnancy as a “physiological stress test” for women that offers the opportunity to identify those at increased risk of cardiovascular disease.1

As pregnancy is a time when women particularly are motivated to improve their health,10 it also presents a valuable opportunity for physicians, including ob.gyns., to make a lifelong impact on the CVH of their patients through early identification, education, and intervention.

They have been shown to predict positive health outcomes in nonpregnant adults. However, until now, CVH had not been assessed in pregnant women.

Perak et al. recently performed the first cross-sectional study of the prevalence of CVH metrics in pregnant women using the AHA definition.3 Using data from the National Health and Nutrition Examination Surveys (NHANES), they used the Life’s Simple 7 metrics to assess CVH in 1,117 pregnant and 8,200 nonpregnant women in the United States aged 20-44 years. Each of the Life’s Simple 7 metrics was scored 0, 1, or 2 points, corresponding to a rating of poor, intermediate, or ideal, respectively. Thus, the total CVH score ranged from 0-14 points, with total scores of 0-7 indicating low CVH, 8-11 indicating moderate CVH, and 12-14 indicating high CVH.

The main study findings were that CVH in pregnant women in the United States was far from optimal, with only 5% having an ideal score, which was even worse than in nonpregnant women, of whom only 13% were scored as having ideal CVH. Ideal scores were observed for 0.1% of pregnant women for diet, 27% for physical activity, 39% for cholesterol levels, 51% for BMI, 78% for smoking, 90% for blood pressure, and 92% for fasting blood glucose. Physical activity and cholesterol levels appeared to be the major drivers of the lower CVH scores in pregnant women.

Although further studies are warranted to determine the relevance of CVH during pregnancy to outcomes for both mother and offspring, the study by Perak et al. is an important step toward the development of pregnancy-specific guidelines and definitions for CVH metrics. These are stated goals of the AHA/ACOG that will help promote CVH in women across their lifespans, but which have not been possible due to scant data.

Emerging data suggest that cumulative lifetime exposure is a significant factor in cardiovascular disease outcomes; therefore, earlier intervention would have a more significant impact. Just as gestational diabetes is a predictor of future type 2 diabetes, CVH earlier in a woman’s life predicts cardiovascular disease later in life.4-7 The best data in this regard come from genetic and other studies of hyperlipidemia, which suggest that lowering lipid levels before symptoms develop may prevent cardiovascular disease. In contrast, treatment of patients with clinically manifest disease neither offers a cure nor prevents the occurrence of most cardiovascular events.

It is a particularly salient point in this regard that there currently are no guidelines on treatment of hypercholesterolemia during pregnancy. Notably, the study by Perak et al. suggested that cholesterol levels may have a significant impact on CVH in pregnant women. There also is emerging data supporting the importance of controlling blood pressure across the lifespan,7,8 including during pregnancy.9

For many women, their ob.gyn. is their primary care physician, and pregnancy is often the first time that a woman will have a substantial interaction with the health care system. The AHA/ACOG advisory panel described pregnancy as a “physiological stress test” for women that offers the opportunity to identify those at increased risk of cardiovascular disease.1

As pregnancy is a time when women particularly are motivated to improve their health,10 it also presents a valuable opportunity for physicians, including ob.gyns., to make a lifelong impact on the CVH of their patients through early identification, education, and intervention.

Cardiovascular disease is both common and chronic, and it remains the leading cause of death in women. Because it is a life-long condition, cardiovascular disease must be managed over the entire lifespan. In recognition of the important role of obstetricians and gynecologists in monitoring women’s health, the American Heart Association/American College of Obstetricians and Gynecologists 2018 guidelines1 promoted the use of “Life’s Simple 7”2 for assessing cardiovascular health (CVH) in women.
