Perinatal HIV transmission and prevention
Abstract
Perinatal HIV transmission occurs during pregnancy, labor, delivery or breastfeeding. Maternal factors associated with increased perinatal transmission include timing of infection, immune status, mode of delivery, co-existing sexually transmitted diseases, illicit drug use, increased duration of ruptured membranes, chorioamnionitis, viral load & invasive procedures. Infant risk factors include premature birth, low birth weight, skin & mucous membrane lesions. Preventive measures include anti retroviral therapy, treatment of chorioamnionitis with antibiotics, opting for caesarean section & avoiding breastfeeding. Early appropriate treatment of subclinical chorioamnionitis & virocidal cleaning of birth canal reduces perinatal HIV transmission. Caesarean section before onset of labour & membrane rupture reduces risk of mother–infant transmission by almost 50%. Vertical HIV transmission can occur through breast-feeding mostly during first 6 weeks of life & hence avoiding breastfeeding reduces transmission. Interrupting intrapartum transmission like giving ART in late gestation/ peri-partum & elective caesarean section reduce vertical HIV acquisition. As monotherapy & dual therapy are less effective, current guidelines recommend 2 nucleoside reverse transcriptase inhibitors & either a nonnucleoside reverse transcriptase inhibitor or a protease inhibitor. Perinatal HIV transmission can be reduced through a comprehensive approach including Universal access to prenatal care & routine HIV counselling & testing, access to antiretroviral therapy during pregnancy, at delivery & postpartum, education about treatment options & regimen adherence.
