BackgroundUniversal multi drug antiretroviral treatment in pregnancy is a global priority in our bid to eliminate paediatric HIV infections although few studies have documented the impact of antiretroviral coverage on overall pregnancy outcomes.MethodsWe conducted a maternity audit at a large regional hospital in South Africa during July-December 2011 and January-June 2014 with an aim to determine an association between pregnancy outcomes and the ARV treatment guidelines implemented during those specific periods. During 2011, women received either Zidovudine/sd Nevirapine or Stavudine/Lamivudine/Nevirapine if CD4+ count was < 350 cells/ml. During 2014, all HIV positive pregnant women were eligible for a fixed dose combination (FDC) of triple ARVs (Tenofovir/Emtracitabine/Efavirenz).ResultsIn 2011, 622 (35.9 %) of 1732 HIV positive pregnant women received triple antiretrovirals (D4T/3TC/NVP) and in 2014, 2104 (94.8 %) of 2219 HIV positive pregnant women received the fixed dose combination (TDF/FTC/EFV). We observed a reduction in the proportion of unregistered pregnancies, caesarean delivery rate, still birth rate, very low birth weight rate, and very premature delivery rate in 2014. In a bivariate analysis of all 9,847 deliveries, unregistered pregnancies (2.2 %) and HIV infection (37.8 %) remained significant risk factors for SB(OR 6.36 and 1.43 respectively), PTD(OR 4.23 and 1.26 respectively),LBW (OR 4.07 and 1.26 respectively) and SGA(OR 2.17 and 1.151 respectively). In a multivariable analysis of HIV positive women only, having received AZT/NVP or D4T/3TC/NVP or EFV/TDF/FTC as opposed to not receiving any ARV was significantly associated with reduced odds of a SB (OR 0.08, 0.21 and 0.18 respectively), PTD (OR 0.52, 0.68 and 0.56 respectively) and LBW(0.37, 0.61 and 0.52 respectively).ConclusionAn improvement in birth outcomes is likely associated with the increased coverage of triple antiretroviral treatment for pregnant women. And untreated HIV infected women and women who do not seek antenatal care should be considered most at risk for poor birth outcomes.
BackgroundAnaemia is a common clinical finding in HIV infected women and has been associated with advanced disease. The use of antiretroviral drugs such as Zidovudine (ZDV) either for prevention of mother to child transmission (MTCT) of HIV or used in combination with other antiretrovirals have been implicated in the development or increased severity of anaemia. We report the prevalence, type, severity and incidence of anaemia in a cohort of HIV infected women who initiated antiretroviral prophylaxis or treatment during pregnancy.Methods and MaterialsThis is a retrospective cohort data analysis of 408 HIV infected pregnant women who participated in a breastfeeding intervention study (HPTN 046 Study, ClinicalTrials.gov NCT 00074412) in South Africa. Women initiated zidovudine prophylaxis for PMTCT or triple antiretroviral treatment in pregnancy according to the standard of care. Laboratory and clinical data in pregnancy, <72 hours and 2 weeks postdelivery were extracted from the main database and analysed.ResultsThe mean Hb concentration was 10.6 g/dL at baseline and 262/408 (64.2%) women were diagnosed with anaemia (Hb<11 g/dL) in pregnancy, 48/146 (32.9%) subsequently developed anaemia intrapartum or postpartum and 89/310 (28.7%) of all cases of anaemia remained unresolved by 2 weeks postdelivery. In a univariate analysis, CD4 count and gravidity were significant risk factors for anaemia in pregnancy, RR 1.41; 1.23–1.61 (p<0.001) and 1.10; 1.01–1.18 (p = 0.02) respectively. After adjusting for antiretroviral regimen, age and gravidity in a multivariable analysis, only the CD4 count remains a significant risk factor for anaemia in pregnancy and postdelivery.ConclusionIn conclusion, anaemia was most common among women in the advanced stage of HIV infection (CD4<200 cells/mm3). There was no evidence of an association between ZDV or triple ARVs and anaemia.
IntroductionPreeclampsia and HIV/AIDS are inflammatory conditions that contribute significantly to adverse maternal and foetal outcomes. The immune reconstitution effects of HAART on inflammatory mediators has not been adequately studied in pregnancy and may impact on the inflammatory cytokine network in women with co-morbid preeclampsia. Our study evaluated changes in pro-inflammatory cytokines IL-2, TNF-α, IFN-γ and IL-6 in HIV infected preeclamptic women on HAART.MethodsA prospective experimental study was conducted at Prince Mshiyeni Memorial Hospital between July 2013 and September 2014. One hundred and ninety three pregnant women were recruited into 4 groups: uninfected normotensive (50; 26%), infected normotensive (45; 23%), uninfected preeclamptic (53; 28%) and infected preeclamptic women (45; 23%). Serum levels of cytokines TNF-α, IFN- γ, IL-2 and IL-6 were determined using commercially available kits and a Cytometric Bead Array (CBA). Comparative data was recorded and analysed descriptively.ResultsIn the control groups (normotensive), significantly lower values were found in IL-2 (p = 0.010), TNF-α (p = 0.045), and IL-6 (p = 0.005); and a non-significant decrease was observed in IFN-γ (p = 0.345) in HIV infected women on HAART compared to uninfected controls. In the experimental group (preeclamptic) women, significantly reduced levels were observed in IL-2 and TNF-α (p = 0.001; p = 0.000) and non-significant decreases were observed in IFN-γ and IL-6 (p = 0.023; p = 0.086) in HIV infected women on HAART compared with uninfected preeclamptic women. Non-significant differences were observed between uninfected preeclamptic and normotensive women.ConclusionIn uncomplicated/normotensive pregnancies, HIV/HAART is associated with significant decreases in IL-2, TNF-α and IL-6, and in preeclamptic women significant decreases in IL-2 and TNF-α were observed. These findings suggest that HIV/HAART impacts on pro-inflammatory cytokines in women with co-morbid preeclampsia. This provides a platform for further research on immune reconstitution effects of HAART during pregnancy, and the development of potential immune modulation therapies for the management of preeclampsia.
BackgroundThe incidence and prevalence of multidrug–resistant tuberculosis (MDR TB) in the province of KwaZulu-Natal, South Africa, are amongst the highest in the world. Previously, interventions have been largely biomedical based; however, there is growing opinion that interventions must include social aspects such as patient education and attitudes.MethodsThis observational study assessed the knowledge and attitudes of 380 patients diagnosed with MDR TB at a centralised MDR TB unit in Durban. Data were collected using a questionnaire that was distributed to every third patient attending the outpatient MDR TB clinic. Data were collected over an 8-week period and analysed descriptively.ResultsJust under half of the respondents had primary MDR TB. Most respondents were young, female unemployed and did not receive a social grant. Knowledge around diagnosis of MDR TB was generally adequate. There were important misconceptions about spread of the disease and duration of treatment. Most respondents received knowledge of MDR TB from healthcare workers. Some respondents received knowledge from friends, family and Sangomas and believed that the disease was caused by bewitchment or as a form of punishment.DiscussionThe need for strengthening the role of primary care physicians in promoting education and providing support is highlighted. Further study is needed to investigate the high rate of primary MDR TB and to identify the unique challenges faced by women who have MDR TB. Future research could include the possibility of involving traditional healers in a contextually sensitive MDR TB education, training and support programme.
