Efficacy of single dose Nevirapine in reducing viral load in HIV positive mother in labour and transmission of HIV infection to new born babies as part of prevention of parent to child transmission

BackgroundPrevention of parent to child transmission (PPTCT) program was initiated in Armed Forces to reduce the vertical transmission of HIV by instituting single dose Nevirapine (sdNVP) in untreated HIV positive mothers in labour. The aim of this study was to evaluate the role of sdNVP to decrease viral load of HIV infected mother during labour and its efficacy in prevention of mother to child transmission of HIV.MethodsThirty antenatal women tested positive for HIV at our PPTCT centre and delivered between Jan 2006 and May 2008 were evaluated. During labour these women were given sdNVP. Newborns were given syrup Nevirapine. The babies were tested for HIV infection at 48 h and six weeks after delivery.ResultsThirty HIV positive women delivered at our centre and four newborns were found positive for HIV infection at 48 h. After six weeks interval three neonates were detected for HIV infection as one infant at six weeks was found to be negative for HIV infection.ConclusionThe protection rate of Nevirapine in untreated HIV positive women is not ideal. It is recommended that all HIV positive women should be offered Highly Active Antiretroviral therapy as primary mode for PPTCT.
