Filter by:The main objective is to evaluate the operationality of introducing the measurement of viral load in HIV-1 infected mothers at delivery by POC to optimise post-natal prophylaxis and neonatal diagnosis of children according to the estimated risk of MTCT (high risk: HIV viral load (VL) at delivery ≥ 1000 copies/mL, low risk: VL at delivery < 1000 copies/mL) in Conakry, Guinea.
Principal objective Assess the operational efficacy of a strategy combining early diagnosis and preventive antiretroviral treatment systematically reinforced from the birth* among infants at high risk of infection with HIV** . - in a maximum of 48 hours after delivery - born from HIV infected mothers who received less than 4 weeks of antiretroviral therapy prior delivery and / or HIV infection diagnosed at delivery Intervention, a combined strategy : After positive HIV infection screening from mother in the delivery room and put on antiretroviral treatment of mothers with post partum according to national guidelines , newborns benefit : - Early detection of HIV infection at birth - Without awaiting the outcome of early detection result, a preventive reinforced antiretroviral treatment (zidovudine, lamivudine, nevirapine or zidovudine, lamivudine if their mother is infected with HIV-2), from birth for 12 weeks. - Regular HIV screening until the end of breastfeeding or later to 18 months. - In case of positive results of an HIV test, an antiretroviral treatment with zidovudine, lamivudine, lopinavir, ritonavir whatever serology HIV 1 or 2.
The study design includes an observational prospective cohort of HIV-positive pregnant/postpartum women and their infants enrolled during antenatal clinics (or immediately postpartum) from prevention of mother-to-child transmission (PMTCT) programs and followed until the infants reach the age of 18 - 24 months and semi-structure interviews with a sub-set of these women. A second study component involves semi-structured interviews with health care workers (HCW) involved in the PMTCT programs and yearly facility surveys at the selected study facilities.
