IntroductionDespite a growing body of research on the risks of SARS-CoV-2 infection during pregnancy, there is continued controversy given heterogeneity in the quality and design of published studies.MethodsWe screened ongoing studies in our sequential, prospective meta-analysis. We pooled individual participant data to estimate the absolute and relative risk (RR) of adverse outcomes among pregnant women with SARS-CoV-2 infection, compared with confirmed negative pregnancies. We evaluated the risk of bias using a modified Newcastle-Ottawa Scale.ResultsWe screened 137 studies and included 12 studies in 12 countries involving 13 136 pregnant women.Pregnant women with SARS-CoV-2 infection-as compared with uninfected pregnant women-were at significantly increased risk of maternal mortality (10 studies; n=1490; RR 7.68, 95% CI 1.70 to 34.61); admission to intensive care unit (8 studies; n=6660; RR 3.81, 95% CI 2.03 to 7.17); receiving mechanical ventilation (7 studies; n=4887; RR 15.23, 95% CI 4.32 to 53.71); receiving any critical care (7 studies; n=4735; RR 5.48, 95% CI 2.57 to 11.72); and being diagnosed with pneumonia (6 studies; n=4573; RR 23.46, 95% CI 3.03 to 181.39) and thromboembolic disease (8 studies; n=5146; RR 5.50, 95% CI 1.12 to 27.12).Neonates born to women with SARS-CoV-2 infection were more likely to be admitted to a neonatal care unit after birth (7 studies; n=7637; RR 1.86, 95% CI 1.12 to 3.08); be born preterm (7 studies; n=6233; RR 1.71, 95% CI 1.28 to 2.29) or moderately preterm (7 studies; n=6071; RR 2.92, 95% CI 1.88 to 4.54); and to be born low birth weight (12 studies; n=11 930; RR 1.19, 95% CI 1.02 to 1.40). Infection was not linked to stillbirth. Studies were generally at low or moderate risk of bias.ConclusionsThis analysis indicates that SARS-CoV-2 infection at any time during pregnancy increases the risk of maternal death, severe maternal morbidities and neonatal morbidity, but not stillbirth or intrauterine growth restriction. As more data become available, we will update these findings per the published protocol.

Background Few data are available on COVID-19 outcomes among pregnant women in sub-Saharan Africa (SSA), where high-risk comorbidities are prevalent. We investigated the impact of pregnancy on SARS-CoV-2 infection and of SARS-CoV-2 infection on pregnancy to generate evidence for health policy and clinical practice. Methods We conducted a 6-country retrospective cohort study among hospitalized women of childbearing age between 1 March 2020 and 31 March 2021. Exposures were (1) pregnancy and (2) a positive SARS-CoV-2 RT-PCR test. The primary outcome for both analyses was intensive care unit (ICU) admission. Secondary outcomes included supplemental oxygen requirement, mechanical ventilation, adverse birth outcomes, and in-hospital mortality. We used log-binomial regression to estimate the effect between pregnancy and SARS-CoV-2 infection. Factors associated with mortality were evaluated using competing-risk proportional subdistribution hazards models. Results Our analyses included 1315 hospitalized women: 510 pregnant women with SARS-CoV-2, 403 nonpregnant women with SARS-CoV-2, and 402 pregnant women without SARS-CoV-2 infection. Among women with SARS-CoV-2 infection, pregnancy was associated with increased risk for ICU admission (adjusted risk ratio [aRR]: 2.38; 95% CI: 1.42–4.01), oxygen supplementation (aRR: 1.86; 95% CI: 1.44–2.42), and hazard of in-hospital death (adjusted sub-hazard ratio [aSHR]: 2.00; 95% CI: 1.08–3.70). Among pregnant women, SARS-CoV-2 infection increased the risk of ICU admission (aRR: 2.0; 95% CI: 1.20–3.35), oxygen supplementation (aRR: 1.57; 95% CI: 1.17–2.11), and hazard of in-hospital death (aSHR: 5.03; 95% CI: 1.79–14.13). Conclusions Among hospitalized women in SSA, both SARS-CoV-2 infection and pregnancy independently increased risks of ICU admission, oxygen supplementation, and death. These data support international recommendations to prioritize COVID-19 vaccination among pregnant women. [ABSTRACT FROM AUTHOR]

Globally, there are prevailing knowledge gaps in the epidemiology, clinical manifestations, and outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among children and adolescents; and these gaps are especially wide in African countries. The availability of robust age-disaggregated data is a critical first step in improving knowledge on disease burden and manifestations of coronavirus disease 2019 (COVID-19) among children. Furthermore, it is essential to improve understanding of SARS-CoV-2 interactions with comorbidities and coinfections such as human immunodeficiency virus (HIV), tuberculosis, malaria, sickle cell disease, and malnutrition, which are highly prevalent among children in sub-Saharan Africa. The African Forum for Research and Education in Health (AFREhealth) COVID-19 Research Collaboration on Children and Adolescents is conducting studies across Western, Central, Eastern, and Southern Africa to address existing knowledge gaps. This consortium is expected to generate key evidence to inform clinical practice and public health policy-making for COVID-19 while concurrently addressing other major diseases affecting children in African countries.

Introduction: About 2.6 million stillbirths per year occur globally with 98% occurring in low- and middle-income countries including Kenya, where an estimated 35 000 stillbirths occur annually. Most studies have focused on the direct causes of stillbirth. The aim of this study was to determine the association between antenatal care utilization and quality with stillbirth in a Kenyan set up. This information is key when planning strategies to reduce the stillbirth burden.Material and Methods: This was a case-control study in four urban tertiary hospitals carried out between August 2018 and April 2019. A total of 214 women with stillbirths (cases) and 428 with livebirths (controls) between 28 and 42 weeks were enrolled. Information was obtained through interviews and data abstracted from medical records. Antenatal care utilization was assessed by the proportions of women not attending antenatal care; booking first antenatal care visit in first trimester and not making the requisite four antenatal care visits. Quality of antenatal care was assessed using individual surrogate indicators (antenatal profile testing, weight/blood pressure/urinalysis testing in each antenatal visit, utilization of early obstetric ultrasound, completeness of antenatal records) and a codified indicator made up of seven parameters (attending antenatal care, booking first antenatal care in the first trimester, making four or more antenatal visits, having all antenatal profile tests, having a complete antenatal record, having blood pressure and weight measured at all visits). The association between antenatal care utilization and quality with stillbirth was assessed using univariate and multivariate analysis using logistic regression. Statistical significance was defined as a two-tailed P value ≤ .05.Results: Women with stillbirth were likely to have a parity ≥4 (19.6% vs 12.6%, P = .02), have an obstetric complication (36% vs 8.6%, P = .001) and have a medical disorder (5.6% vs 1.6%, P = .01). The odds of a stillbirth were four times higher among those who did not attend antenatal care ( odds ratio [OR] 4.1, 95% confidence interval [CI] 1.6-10, P < .003). Compared with four antenatal care visits, those who had one or two visits had higher odds of a stillbirth: OR 2.96 (95% CI 1.4-6.1), P = .003, and OR 2.9 (95% CI 1.7-5), P = .003, respectively. As per the individual surrogate indicators, the likelihood of a stillbirth was lower in women who received good quality antenatal care: Hemoglobin testing (OR 0.6, 95% CI 0.4-0.8, P = .03), blood group test (OR 0.4, 95% CI 0.2-0.6, P < .001), HIV test (OR 0.3, 95% CI 0.2-0.5, P = .001), venereal disease research laboratory test (OR 0.2, 95% CI 0.1-0.4, P = .001), weight measurement (OR 0.7, 95% CI 0.5-1.0, P = .047). As per the composite indicator, the quality of antenatal care was poor across the board and there was no association between this surrogate indicator and stillbirth.Conclusions: Lack of antenatal care, attending fewer than four antenatal visits and poor quality antenatal care as measured by surrogate indicators were significantly associated with stillbirth. In addition, women with low education level, obstetric complications, multiparity and medical complications had a significantly higher likelihood of stillbirth. Improving the utilization of four or more antenatal visits and the quality of antenatal care can reduce the risk of stillbirth. [ABSTRACT FROM AUTHOR]

In the African context, there is a paucity of data on SARS-CoV-2 infection and associated COVID-19 in pregnancy. Given the endemicity of infections such as malaria, HIV, and tuberculosis (TB) in sub-Saharan Africa (SSA), it is important to evaluate coinfections with SARS-CoV-2 and their impact on maternal/infant outcomes. Robust research is critically needed to evaluate the effects of the added burden of COVID-19 in pregnancy, to help develop evidence-based policies toward improving maternal and infant outcomes. In this perspective, we briefly review current knowledge on the clinical features of COVID-19 in pregnancy; the risks of preterm birth and cesarean delivery secondary to comorbid severity; the effects of maternal SARS-CoV-2 infection on the fetus/neonate; and in utero mother-to-child SARS-CoV-2 transmission. We further highlight the need to conduct multicountry surveillance as well as retrospective and prospective cohort studies across SSA. This will enable assessments of SARS-CoV-2 burden among pregnant African women and improve the understanding of the spectrum of COVID-19 manifestations in this population, which may be living with or without HIV, TB, and/or other coinfections/comorbidities. In addition, multicountry studies will allow a better understanding of risk factors and outcomes to be compared across countries and subregions. Such an approach will encourage and strengthen much-needed intra-African, south-to-south multidisciplinary and interprofessional research collaborations. The African Forum for Research and Education in Health's COVID-19 Research Working Group has embarked upon such a collaboration across Western, Central, Eastern and Southern Africa.
