Mother to children transmission (MTCT) rates for HIV can be greatly reduced with anti-retroviral medications. However, according to researchers, a clinical study has not established the effectiveness and safety of oral zidovudine (ZDV) in infants. The treatment protocol is also lacking clinical guidance and support. A new study published in the journal BMC Pregnancy Childbirth examines the effectiveness of postnatal ZDV therapy at preventing MTCT of HIV.
About 120 woman/infant pairs participated in the study. Births took place between 2000 and 2010. Infants were placed in risk groups based on risk factors for infection – low risk, high risk, and very high risk.
Conclusion: Overall MTCT occurred in 1.8% of mother/infant pairs. Only 1.4% of infants in the low-risk group treated with a two-week course of ZDV contracted HIV. No infection rates were listed for the high risk and very high-risk groups. Even if ZDV is used only in low-risk populations, MTCT rates reduce significantly with just two weeks of treatment.
