Impact of aetiological screening of sexually transmitted infections during pregnancy on pregnancy outcomes in South Africa
BACKGROUND: Sexually transmitted infections (STIs) during pregnancy may increase the risk of adverse pregnancy outcomes. STI syndromic management is standard of care in South Africa but has its limitations. We evaluated the impact of diagnosing and treating curable STIs during pregnancy on adverse pregnancy and birth outcomes. METHODS: We combined data from two prospective studies of pregnant women attending public sector antenatal care (ANC) clinics in Tshwane District and Cape Town, South Africa. Pregnant women were enrolled, tested and treated for STIs. We evaluated the association between any STI at the first ANC visit and a composite adverse pregnancy outcome (miscarriage, stillbirth, preterm birth, early neonatal death, or low birthweight) using modified Poisson regression models, stratifying by HIV infection and adjusting for maternal characteristics. RESULTS: Among 619 women, 61% (n =380) were from Tshwane District and 39% (n =239) from Cape Town; 79% (n =486) were women living with HIV. The prevalence of any STI was 37% (n =228); C. trachomatis, 26% (n =158), T. vaginalis, 18% (n =120) and N. gonorrhoeae, 6% (n =40). There were 93% (n =574) singleton live births, 5% (n =29) miscarriages and 2% (n =16) stillbirths. Among the live births, there were 1% (n =3) neonatal deaths, 7% (n =35) low birthweight in full-term babies and 10% (n =62) preterm delivery. There were 24% (n =146) for the composite adverse pregnancy outcome. Overall, any STI diagnosis and treatment at first ANC visit was not associated with adverse outcomes in women living with HIV (adjusted relative risk (aRR); 1.43, 95% CI: 0.95–2.16) or women without HIV (aRR; 2.11, 95% CI: 0.89–5.01). However, C. trachomatis (aRR; 1.57, 95% CI: 1.04–2.39) and N. gonorrhoeae (aRR; 1.69, 95% CI: 1.09–3.08), were each independently associated with the composite adverse outcome in women living with HIV. CONCLUSION: Treated STIs at the first ANC visit were not associated with adverse pregnancy outcome overall. In women living with HIV, C. trachomatis or N. gonorrhoeae at first ANC were each independently associated with adverse pregnancy outcome. Our results highlights complex interactions between the timing of STI detection and treatment, HIV infection and pregnancy outcomes, which warrants further investigation.Eunice Kennedy Shriver Institute of Child Health and Human Development, National Institute of Allergy and Infectious Diseases & National Institutes of Health.http://www.biomedcentral.com/bmcpregnancychildbirthMedical Microbiolog
2020 Visions
For the first issue of the new decade, Nature asked a selection of leading researchers and policy-makers where their fields will be ten years from now. We invited them to identify the key questions their disciplines face, the major roadblocks and the pressing next steps
