Factors associated with disparate outcomes among Black women undergoing in vitro fertilization.

Objective: To determine if Black women have worse in vitro fertilization (IVF) outcomes than women of other races/ethnicities, and to establish which factors are associated with the IVF outcomes of Black women. Design: Retrospective cohort study. Setting: Not applicable. Patients: All patients undergoing IVF. Interventions: Not applicable. Main Outcome Measures: Spontaneous abortion rate, clinical pregnancy rate, and live birth rate. Results: A total of 71,389 patient cycles were analyzed. Of the 40,545 patients who were included, 6.4% of patients were Black, 62% were White, 7.3% were Hispanic/Latino, and 15% were Asian. After IVF, Black women had significantly more miscarriages than White but not Hispanic or Asian patients (8.0% Black vs. 6.9% White, 7.4% Hispanic, and 7.5% Asian). Clinical pregnancy rates were significantly lower for Black women compared with all other races (45% Black vs. 52% White, 52% Hispanic, and 53% Asian). The odds ratio (OR) of live birth from all cycles were 30% less than that for White women (OR, 1.00 Black vs. 1.43 White) and 22% less than that for Hispanic women (OR, 1.00 Black vs. 1.29 Hispanic). This statistically significant difference in the live birth rate persisted even after adjusting for patient characteristics (OR, 1.00 Black vs. 1.32 White, 1.23 Hispanic, and 1.18 Asian). Conclusions: Black women have worse IVF outcomes than women of all other racial backgrounds undergoing IVF. The factors associated with the disparate outcomes of Black women undergoing IVF outcomes include older age starting IVF, higher body mass index, tubal factor infertility, and diabetes.

Management of a Novel Autoimmune Disease, COPA Syndrome, in Pregnancy.

Background: COPA syndrome is a rare autoimmune disease, demonstrating an autosomal dominant inheritance pattern with variable penetration that occurs more frequently in females than males. This disease manifests in childhood as pulmonary hemorrhage, arthritis, and renal disease. Case: We present a case of obstetric management of a 20-year-old nulligravida patient with a diagnosis of COPA syndrome. Her case was further complicated by multiple antepartum admissions for hypoxemia and a complex psychosocial history of substance use. On her first antepartum admission, rheumatology recommended management with hydroxychloroquine, inhaled corticosteroids (budesonide), and bronchodilators (albuterol inhaler) as needed. On admission for induction of labor, she was again noted to have oxygen desaturations. A chronic thrombus was noted on computed tomography (CT), and a multidisciplinary team was recommended against Valsalva. Thus, she had a primary cesarean delivery. Her postpartum course was only remarkable for improved oxygenation status. Conclusion: Management of COPA syndrome should be performed by a multidisciplinary team including maternal-fetal medicine, rheumatology, and pulmonology specialists. Traditionally, COPA syndrome is treated with immunomodulator therapy often used to treat autoimmune syndromes. However, many of these medications are not well studied or contraindicated in pregnancy. Preconception counseling is recommended both to ensure pregnancy safe medications being prescribed and to provide information on the genetic inheritance of this disease. At time of entry to care, patients should have a baseline work-up including a radiographic imaging, complete blood count, complete metabolic panel, lactate dehydrogenase, and a 24-hour urine protein collection for baseline. Although thought to be rare, COPA syndrome has an autosomal dominance pattern of inheritance with variable penetrance that is more common in females. Thus, incidence of COPA syndrome in pregnancy will likely increase in the future. Further case studies are warranted to optimize management of patients with COPA syndrome in pregnancy.

Novel intragraft regulatory lymphoid structures in kidney allograft tolerance.

Intragraft events thought to be relevant to the development of tolerance are here subjected to a comprehensive mechanistic study during long-term spontaneous tolerance that occurs in C57BL/6 mice that receive life sustaining DBA/2 kidneys. These allografts rapidly develop periarterial Treg-rich organized lymphoid structures (TOLS) that form in response to class II but not to class I MHC disparity and form independently of lymphotoxin α and lymphotoxin ß receptor pathways. TOLS form in situ in the absence of lymph nodes, spleen, and thymus. Distinctive transcript patterns are maintained over time in TOLS including transcripts associated with Treg differentiation, T cell checkpoint signaling, and Th2 differentiation. Pathway transcripts related to inflammation are expressed in early stages of accepted grafts but diminish with time, while B cell transcripts increase. Intragraft transcript patterns at one week posttransplant distinguish those from kidneys destined to be rejected, that is, C57BL/6 allografts into DBA/2 recipients, from those that will be accepted. In contrast to inflammatory tertiary lymphoid organs (iTLOs) that form in response to chronic viral infection and transgenic Lta expression, TOLS lack high endothelial venules and germinal centers. TOLS represent a novel, pathogenetically important type of TLO that are in situ markers of regulatory tolerance.

Infectious morbidity of speculum versus digital examinations in preterm prelabor rupture of membranes: a systematic review and meta-analysis.

OBJECTIVE: To estimate the effect of speculum examination only versus digital cervical examination on maternal infectious morbidity in women with preterm prelabor rupture of membranes by performing a systematic review and meta-analysis. MATERIALS AND METHODS: We explored MEDLINE, Scopus, Embase, CINAHL, ClinicalTrials.gov and Cochrane Central Register of Controlled Trials for studies comparing the rate of a composite maternal infectious morbidity (either chorioamnionitis, endometritis or both) in women with preterm prelabor rupture of membranes that underwent a speculum only versus digital cervical examination at the time of diagnosis. Two reviewers separately ascertained studies, obtained data, and gauged study quality. The rate of a composite maternal infectious morbidity (either chorioamnionitis, endometritis or both) were compared and odds ratios (ORs) with 95% confidence intervals (CIs) were estimated. RESULTS: Four cohort studies, reporting on 1213 women were identified. The median point prevalence of the composite maternal infectious morbidity was 26% (interquartile range 15-35%) in women who had a speculum examination only compared to 33% (interquartile range 22-42%) in women who underwent a digital examination. The overall maternal composite infectious morbidity rate in women that had a speculum examination only was less compared to women that had undergone a digital examination (pooled OR 0.75, 95% CI 0.58-0.98, I2 17%). The weighted mean length of latency in women with preterm prelabor rupture of membranes was longer in individuals evaluated by speculum only versus digital examination, 6.6 d versus 2.9 d (mean difference 4.5 d, 95% CI 1.4 to 7.8, I2 99%). CONCLUSION: Speculum examination only in women with preterm prelabor rupture of membranes is associated with less maternal infectious morbidity and longer latency periods.
