Breastfeeding Initiation in People With Hepatitis C Virus Infection in the United States.

OBJECTIVE: To evaluate breastfeeding initiation rates among people living with and without hepatitis C virus (HCV) infection during pregnancy and to identify characteristics associated with breastfeeding initiation. METHODS: We conducted a cross-sectional analysis of individuals who had a live birth in the United States from 2016 to 2021 using the National Center for Health Statistics birth certificate data. We grouped participants by whether they had HCV infection during pregnancy. Using propensity-score matching, we assessed the association between breastfeeding initiation before hospital discharge , defined as neonates receiving any parental breast milk or colostrum, and HCV infection during pregnancy in a logistic regression model. We also assessed factors associated with breastfeeding initiation among those with HCV infection. RESULTS: There were 96,896 reported cases (0.5%) of HCV infection among 19.0 million births that met inclusion criteria during the study period. Using propensity-score matching, we matched 87,761 individuals with HCV infection during pregnancy with 87,761 individuals without HCV infection. People with HCV infection during pregnancy were less likely to initiate breastfeeding compared with those without HCV infection (51.5% vs 64.2%, respectively; odds ratio 0.59, 95% CI, 0.58-0.60, P <.001). Characteristics associated with higher rates of breastfeeding initiation among individuals with HCV infection included a college degree (adjusted odds ratio [aOR] 1.22, 95% CI, 1.21-1.24); self-identified race or ethnicity as Native Hawaiian or Pacific Islander (aOR 1.22, 95% CI, 1.06-1.40), Asian (aOR 1.09, 95% CI, 1.06-1.13), or Hispanic (aOR 1.09, 95% CI, 1.08-1.11); private insurance (aOR 1.07, 95% CI, 1.06-1.08); nulliparity (aOR 1.09, 95% CI, 1.08-1.10), and being married (aOR 1.08, 95% CI, 1.07-1.09). Characteristics associated with not breastfeeding before hospital discharge included receiving no prenatal care (aOR 0.81, 95% CI, 0.79-0.82), smoking during pregnancy (aOR 0.88, 95% CI, 0.88-0.89), and neonatal intensive care unit admission (aOR 0.92, 95% CI, 0.91-0.93). CONCLUSION: Despite leading health organizations' support for people living with HCV infection to breastfeed, our study demonstrates low breastfeeding initiation rates in this population. Our findings highlight the need for tailored breastfeeding support for people with HCV infection and for understanding the additional effects of human immunodeficiency virus (HIV) co-infection, HCV treatment, and concurrent substance use disorders on breastfeeding initiation.

Perinatal Outcomes Among Patients With Sepsis During Pregnancy.

Importance: Rates of maternal sepsis are increasing, and prior studies of maternal sepsis have focused on immediate maternal morbidity and mortality associated with sepsis during delivery admission. There are no data on pregnancy outcomes among individuals who recover from their infections prior to delivery. Objective: To describe perinatal outcomes among patients with antepartum sepsis who did not deliver during their infection hospitalization. Design, Setting, and Participants: This retrospective cohort study was conducted using data from August 1, 2012, to August 1, 2018, at an academic referral center in San Francisco, California. Included patients were all individuals with nonanomalous, singleton pregnancies who delivered after 20 weeks' gestation during the study period. Data were analyzed from March 2020 through March 2021. Exposures: Antepartum admission for infection with clinical concern for sepsis and hospital discharge prior to delivery. Main Outcomes and Measures: The primary outcome was a composite of perinatal outcomes associated with placental dysfunction and consisted of 1 or more of the following: fetal growth restriction, oligohydramnios, hypertensive disease of pregnancy, cesarean delivery for fetal indication, child who is small for gestational age, or stillbirth. Results: Among 14 565 patients with nonanomalous singleton pregnancies (mean [SD] age at delivery, 33.1 [5.2] years), 59 individuals (0.4%) were in the sepsis group and 14 506 individuals (99.6%) were in the nonsepsis group; 8533 individuals (59.0%) were nulliparous. Patients with sepsis, compared with patients in the reference group, were younger (mean [SD] age at delivery, 30.6 [5.7] years vs 33.1 [5.2] years; P < .001), were more likely to have pregestational diabetes (5 individuals [8.5%] vs 233 individuals [1.6%]; P = .003), and had higher mean (SD) pregestational body mass index scores (26.1 [6.1] vs 24.4 [5.9]; P = .03). In the sepsis group, the most common infections were urinary tract infections (24 patients [40.7%]) and pulmonary infections (22 patients [37.3%]). Among patients with sepsis, 5 individuals (8.5%) were admitted to the intensive care unit, the mean (SD) gestational age at infection was 24.6 (9.0) weeks, and the median (interquartile range) time from infection to delivery was 82 (42-147) days. Antepartum sepsis was associated with higher odds of placental dysfunction (21 patients [35.6%] vs 3450 patients [23.8%]; odds ratio, 1.77; 95% CI, 1.04-3.02; P = .04). On multivariable logistic regression analysis, antepartum sepsis was an independent factor associated with placental dysfunction (adjusted odds ratio, 1.88; 95% CI, 1.10-3.23; P = .02) after adjusting for possible confounders. Conclusions and Relevance: This study found that pregnancies complicated by antepartum sepsis were associated with higher odds of placental dysfunction. These findings suggest that increased antenatal surveillance should be considered for these patients.

Acute Respiratory Distress Syndrome in a Preterm Pregnant Patient With Coronavirus Disease 2019 (COVID-19).

BACKGROUND: Data suggest that pregnant women are not at elevated risk of acquiring severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or developing severe disease compared with nonpregnant patients. However, management of pregnant patients who are critically ill with coronavirus disease 2019 (COVID-19) infection is complicated by physiologic changes and other pregnancy considerations and requires balancing maternal and fetal well-being. CASE: We report the case of a patient at 28 weeks of gestation with acute respiratory distress syndrome (ARDS) from COVID-19 infection, whose deteriorating respiratory condition prompted delivery. Our patient's oxygenation and respiratory mechanics improved within hours of delivery, though she required prolonged mechanical ventilation until postpartum day 10. Neonatal swabs for SARS-CoV-2 and COVID-19 immunoglobulin (Ig) G and IgM were negative. CONCLUSION: We describe our multidisciplinary management of a preterm pregnant patient with ARDS from COVID-19 infection and her neonate.
