RESUMO

Aripiprazole has become one of the most commonly prescribed psychotropics, making a more comprehensive understanding of its reproductive safety profile a priority. The goal of the current analysis was to determine the risk of major malformations in infants exposed during the first trimester of pregnancy to aripiprazole compared to infants whose mothers had psychiatric diagnoses but did not use an atypical antipsychotic during pregnancy. The National Pregnancy Registry for Atypical Antipsychotics is a prospective pharmacovigilance program in which pregnant women are enrolled and interviewed during pregnancy and the postpartum period. Medical records are assessed to confirm presence or absence of major malformations. Pregnant women ages 18-45 with psychiatric diagnoses are enrolled. As of April 2020, N = 848 women who had delivered infants were eligible for analyses. A total of 158 women with first trimester exposure to aripiprazole were compared to 690 controls. For 163 infants born to women in the exposed group, seven major malformations were confirmed (4.29%), compared to fourteen of the 690 unexposed infants (1.99%). The unadjusted odds ratio for major malformations between aripiprazole-exposed and unexposed infants was 2.21 (95% confidence interval [CI] = (0.88, 5.57) The adjusted odds ratio for major malformations was 1.35 (95% confidence interval [CI] = (0.43, 4.20). After adjustment for confounding variables, the risk of major malformations after first trimester exposure to aripiprazole was not significant compared to controls. While these results are reassuring, they are limited by relatively small numbers of participants. Future analyses with larger numbers are expected to provide more of a complete and precise reproductive safety profile regarding aripiprazole use during pregnancy. Trial registration: clinicaltrials.gov NCT01246765.

RESUMO

BACKGROUND: Women often seek antidepressant alternatives for major depressive disorder (MDD) in anticipation of or during pregnancy. In this preliminary study, EnBrace HR, a prenatal supplement containing methylfolate, was investigated for depressive relapse prevention and for acute treatment of MDD in women planning pregnancy or during pregnancy. METHODS: This 12-week open-label study included women with histories of MDD who were planning pregnancy or pregnant < 28 weeks. At enrollment, Group 1 participants were well (not depressed) and planned to discontinue antidepressants for pregnancy. Group 2 participants were depressed. Primary outcome variables by group included MDD relapse and depressive symptoms, verified with the Mini-International Neuropsychiatric Interview and the Montgomery-Åsberg Depression Rating Scale (MADRS), respectively. Biomarkers of inflammation and the folate cycle were collected. RESULTS: Group 1 participants (N = 11) experienced lower rates of depressive relapse (27.3% P = .005) than expected from a historical comparison group and no significant changes in MADRS scores. Group 2 participants (N = 6) experienced significant improvements in MADRS scores (P = .001), with 5 (83.3%) improving >50% and 1 improving 33.3%. One adverse event occurred, a hospitalization for depression. CONCLUSIONS: Results suggest EnBrace HR is a well-tolerated intervention with potential efficacy for prevention and treatment of perinatal depression. Larger controlled trials are necessary.

RESUMO

Proteasomes are critical for peripheral nervous system (PNS) function. Here, we investigate mammalian PNS proteasomes and reveal the presence of the neuronal membrane proteasome (NMP). We show that specific inhibition of the NMP on distal nerve fibers innervating the mouse hind paw leads to reduction in mechanical and pain sensitivity. Through investigating PNS NMPs, we demonstrate their presence on the somata and proximal and distal axons of a subset of dorsal root ganglion (DRG) neurons. Single-cell RNA sequencing experiments reveal that the NMP-expressing DRGs are primarily MrgprA3+ and Cysltr2+. NMP inhibition in DRG cultures leads to cell-autonomous and non-cell-autonomous changes in Ca2+ signaling induced by KCl depolarization, αß-meATP, or the pruritogen histamine. Taken together, these data support a model whereby NMPs are expressed on a subset of somatosensory DRGs to modulate signaling between neurons of distinct sensory modalities and indicate the NMP as a potential target for controlling pain.

RESUMO

OBJECTIVE: Postpartum psychosis (PP) is a severe psychiatric disorder, with incomplete consensus on definition and diagnostic criteria. The Massachusetts General Hospital Postpartum Psychosis Project (MGHP3) was established to better ascertain the phenomenology of PP in a large cohort of diverse women spanning a wide geographical range (primarily in the US), including time of onset, symptom patterns, and associated comorbidities, psychiatric diagnoses pre- and post- the episode of PP, and also to identify genomic and clinical predictors of PP. This report describes the methods of MGHP3 and provides a status update. METHOD: Data are collected from women who experienced PP within 6 months of childbirth and who provided this information within ten years of the study interview. Subject data are gathered during a one-time structured clinical interview conducted by phone, which includes administration of the Mini International Neuropsychiatric Interview for Psychotic Disorders Studies (Version 7.0.2), the MGHP3© Questionnaire, and other information including lifetime mental health history and use of psychiatric medications both prior to the episode of PP and during the subsequent time period prior to study interview. Subjects also provide a saliva sample to be processed for genomic analyses; a neuroimaging assessment is also conducted for a subset of participants. RESULTS: As of July 1, 2022, 311 subjects from 44 states and 7 countries were enrolled in MGHP3. Recruitment sources include social media, online advertisements, physician referral, community outreach, and partnership with PP advocacy groups. CONCLUSIONS: The rigorous phenotyping, genetic sampling, and neuroimaging studies in this sample of women with histories of PP will contribute to better understanding of this serious illness. Findings from MGHP3 can catalyze ongoing discussions in the field regarding proper nosologic classification of PP as well as relevant treatment implications.

RESUMO

Background: Second-generation antipsychotics (SGAs), also called atypical antipsychotics, are common therapies for women with a spectrum of psychiatric disorders. No systematically ascertained human reproductive safety data are available for lurasidone, and prospective data for quetiapine are limited, making decisions regarding use of these medications during pregnancy complicated. Materials and Methods: The National Pregnancy Registry for Psychiatric Medications is a prospective cohort study designed to collect reproductive safety data relative to SGAs. Pregnant women aged 18-45 years, with psychiatric illness and prenatal psychotropic medication exposure completed three phone interviews during pregnancy and the postpartum period. Cases of presumed malformations are abstracted from medical records for adjudication by a teratologist blinded to medication exposure. Results: Of 2,293 women enrolled at the time of analysis, 134 in the lurasidone group, 264 in the quetiapine group, and 886 controls completed the postpartum interview and were therefore eligible for inclusion. Dropped or lost-to-follow-up participants (13%) and those currently pregnant were excluded. Participants were predominantly White, college-educated, and married (lurasidone = 88.1%, 76.9%, 77.6%; quetiapine = 89.8%, 71.2%, 75.0%; controls = 92.7%, 86.7%, 89.1%). Absolute risks of major malformations were 2.19% (lurasidone), 1.85% (quetiapine), and 1.77% (controls). Odds ratios comparing lurasidone and quetiapine with controls were 1.24 (95% confidence interval [CI] = 0.36-4.32) and 1.04 (95% CI = 0.38-2.85), respectively. Conclusions: No specific patterns of malformations were observed in infants exposed to the medications of interest. Lurasidone and quetiapine did not appear to be major teratogens, but further information is needed to refine risk estimates. Food and Drug Administration guidance underscores the importance of pregnancy registries. Clinical trial number: NCT01246765.

RESUMO

Objective: Second-generation antipsychotics (SGAs) are prescribed for a wide range of indications in women of reproductive age. The National Pregnancy Registry for Atypical Antipsychotics (NPRAA) was established to determine the risk of major malformations among infants exposed to these medications during the first trimester relative to a comparison group of unexposed infants of mothers with histories of psychiatric morbidity.Methods: Women, aged 18-45 years, with histories of psychiatric illness were prospectively followed through pregnancy and during the postpartum period. Pediatric and maternal medical records were obtained and screened for evidence of major malformations. Potential cases were adjudicated by a dysmorphologist who was blinded to drug exposure.. Recruitment to the Registry, which is based at the Ammon-Pinizzotto Center for Women's Mental Health at Massachusetts General Hospital (MGH), includes nationwide provider referral, self-referral, and advertisement through the MGH Center for Women's Mental Health website.Results: As of April 9, 2020, 1,906 women had enrolled, including 889 in the exposure group and 1,017 controls. A total of 1,311 women completed the study and were eligible for inclusion in the analysis. Medical records were obtained for 81.3% of participants. Among 640 live births in the exposure group, 16 (2.50%) had confirmed major malformations reported, and among 704 live births in the control group, 14 (1.99%) had confirmed major malformations reported. The estimated odds ratio for major malformations comparing exposed and unexposed infants was 1.48 (95% CI, 0.625-3.517).Conclusions: Data from the Registry assessing SGAs as a class indicate that they are unlikely to have a major teratogenic effect. These findings provide pertinent information for women and their health care providers regarding decisions about atypical antipsychotic use during pregnancy.Trial Registration: ClinicalTrails.gov identifier: NCT01246765.

RESUMO

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic control will require widespread access to accurate diagnostics. Salivary sampling circumvents swab supply chain bottlenecks, is amenable to self-collection, and is less likely to create an aerosol during collection compared with the nasopharyngeal swab. METHODS: We compared real-time reverse-transcription polymerase chain reaction Abbott m2000 results from matched salivary oral fluid (gingival crevicular fluid collected in an Oracol device) and nasal-oropharyngeal (OP) self-collected specimens in viral transport media from a nonhospitalized, ambulatory cohort of coronavirus disease 2019 (COVID-19) patients at multiple time points. These 2 sentences should be at the beginning of the results. RESULTS: There were 171 matched specimen pairs. Compared with nasal-OP swabs, 41.6% of the oral fluid samples were positive. Adding spit to the oral fluid percent collection device increased the percent positive agreement from 37.2% (16 of 43) to 44.6% (29 of 65). The positive percent agreement was highest in the first 5 days after symptoms and decreased thereafter. All of the infectious nasal-OP samples (culture positive on VeroE6 TMPRSS2 cells) had a matched SARS-CoV-2 positive oral fluid sample. CONCLUSIONS: In this study of nonhospitalized SARS-CoV-2-infected persons, we demonstrate lower diagnostic sensitivity of self-collected oral fluid compared with nasal-OP specimens, a difference that was especially prominent more than 5 days from symptom onset. These data do not justify the routine use of oral fluid collection for diagnosis of SARS-CoV-2 despite the greater ease of collection. It also underscores the importance of considering the method of saliva specimen collection and the time from symptom onset especially in outpatient populations.

RESUMO

BACKGROUND: Sustained molecular detection of SARS-CoV-2 RNA in the upper respiratory tract (URT) in mild to moderate COVID-19 is common. We sought to identify host and immune determinants of prolonged SARS-CoV-2 RNA detection. METHODS: Ninety-five outpatients self-collected mid-turbinate nasal, oropharyngeal (OP), and gingival crevicular fluid (oral fluid) samples at home and in a research clinic a median of 6 times over 1-3 months. Samples were tested for viral RNA, virus culture, and SARS-CoV-2 and other human coronavirus antibodies, and associations were estimated using Cox proportional hazards models. RESULTS: Viral RNA clearance, as measured by SARS-CoV-2 RT-PCR, in 507 URT samples occurred a median (IQR) 33.5 (17-63.5) days post-symptom onset. Sixteen nasal-OP samples collected 2-11 days post-symptom onset were virus culture positive out of 183 RT-PCR positive samples tested. All participants but one with positive virus culture were negative for concomitant oral fluid anti-SARS-CoV-2 antibodies. The mean time to first antibody detection in oral fluid was 8-13 days post-symptom onset. A longer time to first detection of oral fluid anti-SARS-CoV-2 S antibodies (aHR 0.96, 95% CI 0.92-0.99, p=0.020) and BMI ≥ 25kg/m 2 (aHR 0.37, 95% CI 0.18-0.78, p=0.009) were independently associated with a longer time to SARS-CoV-2 viral RNA clearance. Fever as one of first three COVID-19 symptoms correlated with shorter time to viral RNA clearance (aHR 2.06, 95% CI 1.02-4.18, p=0.044). CONCLUSIONS: We demonstrate that delayed rise of oral fluid SARS-CoV-2-specific antibodies, elevated BMI, and absence of early fever are independently associated with delayed URT viral RNA clearance.

RESULTS: Viral RNA clearance, as measured by SARS-CoV-2 reverse transcription polymerase chain reaction (RT-PCR), in 507 URT samples occurred a median (interquartile range) 33.5 (17-63.5) days post-symptom onset. Sixteen nasal-OP samples collected 2-11 days post-symptom onset were virus culture positive out of 183 RT-PCR-positive samples tested. All participants but 1 with positive virus culture were negative for concomitant oral fluid anti-SARS-CoV-2 antibodies. The mean time to first antibody detection in oral fluid was 8-13 days post-symptom onset. A longer time to first detection of oral fluid anti-SARS-CoV-2 S antibodies (adjusted hazard ratio [aHR], 0.96; 95% CI, 0.92-0.99; P = .020) and body mass index (BMI) ≥25 kg/m2 (aHR, 0.37; 95% CI, 0.18-0.78; P = .009) were independently associated with a longer time to SARS-CoV-2 viral RNA clearance. Fever as 1 of first 3 COVID-19 symptoms correlated with shorter time to viral RNA clearance (aHR, 2.06; 95% CI, 1.02-4.18; P = .044). CONCLUSIONS: We demonstrate that delayed rise of oral fluid SARS-CoV-2-specific antibodies, elevated BMI, and absence of early fever are independently associated with delayed URT viral RNA clearance.

RESUMO

In a large cohort of ambulatory confirmed COVID-19 patients with multiple self-collected sample time points, we compared 202 matched nasal-oropharyngeal swabs and oral salivary fluid sample pairs by RT-PCR. Nasal-oropharyngeal swabs were more sensitive than this salivary sample type (oral crevicular fluid) suggesting that not all saliva sample types have equivalent sensitivity. However, all samples that were Vero E6-TMPRSS2 cell culture positive (e.g., infectious virus) were also oral fluid RT-PCR positive suggesting that oral fluid may find the patients most likely to transmit disease to others.

RESUMO

OBJECTIVE: Obesity is associated with an increased risk of adverse pregnancy outcomes. As individuals with psychiatric disorders are at a higher risk of obesity than the general population, we aimed to examine the effect of obesity on neonatal and maternal outcomes in this population. METHODS: Pregnant women with psychiatric disorders were enrolled in the Massachusetts General Hospital National Pregnancy Registry for Psychiatric Medications (NCT01246765) and followed prospectively until 6 months postpartum. Pre-pregnancy body mass index was used to categorize participants as normal-weight, overweight, and obese to assess comparative risk of adverse outcomes. RESULTS: Within our sample of 584 participants (N = 252 normal-weight; N = 170 overweight; N = 162 obese), obesity was not significantly associated with higher risk for birth defects (OR: 3.19; 95% CI:0.79,12.95; p = 0.10; unadjusted due to the rarity of this outcome in the sample). After adjustment, women with obesity were at higher risk for gestational diabetes (p = 0.011; OR:3.23; 95% CI:1.30,7.98), as were women in the overweight BMI category (p = 0.003; OR:3.77; 95% CI:1.58,9.00). Among women with obesity, there was a tendency for a higher C-section rate (p = 0.07) compared to women in the normal-weight BMI category. Other outcomes were not significantly different among groups. CONCLUSIONS: Peripartum complications associated with obesity are common among women with psychiatric illness; thus, it is important to develop antenatal weight management interventions for this population.

RESUMO

OBJECTIVE: The goal of this analysis was to examine the effect of benzodiazepine use during pregnancy on maternal and neonatal outcomes in a cohort of women with psychiatric disorders. METHODS: 794 evaluable women from the Massachusetts General Hospital National Pregnancy Registry for Psychiatric Medications were followed across pregnancy (N = 144 exposed to benzodiazepines and N = 650 unexposed). Data obtained through maternal report and medical records included maternal outcomes (cesarean section, preeclampsia) and neonatal outcomes (birth weight, breathing difficulty, feeding difficulty, head circumference, 5-minute Apgar score, muscular and/or extrapyramidal symptoms, NICU admission, prematurity). RESULTS: In adjusted analyses, infants exposed to benzodiazepines in utero were more likely to be admitted to the NICU (OR: 2.02, 95% CI: 1.11, 3.66) and to have small head circumferences (OR: 3.89, 95% CI: 1.25, 12.03) compared to unexposed infants. Other neonatal adverse effects such as respiratory distress or muscular symptoms including hypotonia were not observed. There were no significant differences in adverse obstetrical outcomes. CONCLUSIONS: Infants exposed to benzodiazepines during pregnancy had an increased risk of NICU admissions and small head circumferences. Confounding from psychiatric symptoms and other variables cannot be ruled out as contributors to these findings.
