Time of HIV diagnosis, CD4 count and viral load at antenatal care start and delivery in South Africa.

BACKGROUND:Despite the success of prevention of mother to child transmission (PMTCT) program in South Africa, the 30% HIV prevalence among women of childbearing age requires the PMTCT program to be maximally efficient to sustain gains in the prevention of vertical HIV transmission. We aimed to determine the immunologic and virologic status at entry into antenatal care (ANC) and at childbirth among HIV positive women who conceived under the CD418 years) postpartum women who gave birth between September 2016 and December 2017. Demographic, viral load (VL) and CD4 data at ANC start (3-9 months before delivery) and delivery (3 months before/after) were obtained from medical records of consenting women. We compared CD4≥500 cell/μl and viral load (VL) suppression (<400 copes/ml) rates at ANC start and delivery among women with a pre-pregnancy ART, women known HIV positive but with in-pregnancy ART and newly diagnosed women with in-pregnancy ART. Predictors of having a high CD4 and suppressed VL were assessed by log-binomial regression. RESULTS:Of the 692 participants, 394 (57.0%) had CD4 data and 326 (47.1%) had VL data. Overall women with a pre-pregnancy ART were more likely to start ANC with CD4 count≥500 cell/μl (46.3% vs 24.8%, adjusted risk ratio (aRR) = 1.9; 95% confidence interval (95% CI): 1.4-2.5), compared to newly diagnosed women. This difference was no longer apparent at the time of delivery (aRR 1.2 95% CI: 0.4-3.7). Similarly, viral suppression at delivery was higher among women with pre-pregnancy ART (87.2% vs 69.3%, aRR 1.3, 95% CI: 1.1-1.6) as compared to the newly diagnosed women. Viral suppression rate among newly diagnosed women increased substantially by the time of delivery from 43.5% to 69.3% (p = 0.001). CONCLUSION:These results show that pre-pregnancy ART improves immunologic and virologic control during pregnancy and call for renewed efforts in HIV testing, linkage to ART and viral monitoring

Prevalence and predictors of postpartum depression by HIV status and timing of HIV diagnosis in Gauteng, South Africa.

BackgroundPostpartum depression (PPD) is a common mental health condition that can compromise the quality of life and functional capacity of mothers and cause health and developmental problems in children born to affected mothers.ObjectivesWe set out to measure the prevalence of PPD comparing postpartum HIV-1 infected women with pre-pregnancy HIV care experience, newly diagnosed (in latest pregnancy) HIV-1 infected women and HIV negative women, and to identify predictors of major PPD among these women in a peri-urban clinic in South Africa.MethodsWe conducted a cross-sectional survey of 1151 adult (≥18 years) postpartum HIV-1 infected (690) and HIV negative (461) women who delivered up to 30 days before study enrolment, interviewed after their first post-natal visit (3-6 days post- delivery) at Midwife Obstetric Units in Gauteng, South Africa. PPD was categorised into no depression (CES-D 10 total score ResultsOverall 288 (25.0%) women screened positive for postpartum depression, a total of 168 (14.6%) women had low to medium PPD and 120 (10.4%) had major PPD. A higher proportion of HIV negative women experienced PPD, 129/461 (28.0%) among HIV negative vs. 159/690 (23.0%) among HIV-1 infected. Among HIV positive women, there was no meaningful difference in PPD between newly HIV diagnosed and those diagnosed before the most recent pregnancy (aOR 1.3, 95% confidence interval (CI): 0.9-1.8). Predictors of PPD among HIV positive women were living with friends/in a house-share (aOR 0.5 for house-share vs. own home, 95% CI: 0.3-0.9), and attending antenatal care (ANC) for the most recent pregnancy (aOR 0.2 for ANC attendance vs. no ANC attendance, 95% CI: 0.0-0.5). Living with friends/in a house-share was also a predictor of PPD among HIV negative women (aOR 0.4 for house-share vs. own home, 95% CI: 0.2-0.8).Conclusions and recommendationsTargeted symptom screening based on identified risk factors should be considered for postpartum women to increase PPD case-finding and referral to specialised social support services
