Abstract
The aim of this study was to assess the frequency of side effects of antiretroviral treatment in transmission prophylaxis in preterm and near-term infants with a history of HIV-positive mothers. A retrospective single-centre study of all neonates born to HIV-positive mothers between 2001 and 2005 and receiving antiretroviral prophylaxis was performed. Respiratory distress was documented as well as possible side effects from antiretroviral drug treatment, e. g., anaemia, need for transfusion, liver and kidney dysfunction, depression of white blood cell count, feeding problems and nosocomial infections. A comparison was made between a group of preterm infants of less than 35 weeks of gestation with one of near-term neonates of more than 34 weeks. To evaluate the influence of prematurity on the frequency of symptoms, a matched pairs group of 50 preterm infants was established as the control group. Anaemia at birth (24 vs. 27 %), transient signs of liver impairment (24 vs. 16.5 %) or kidney dysfunction (4 vs. 0.8 %) as well as nosocomial infections were not significantly more frequent in the preterm group than in near-term group of HIV-exposed infants. Respiratory distress (56 vs. 13 %), postnatal anaemia (84 vs. 27 %). leucocytopenia (36 vs. 4 %), feeding problems (88 vs. 42 %), and blood transfusion (32 vs. 7 %) were more common in the preterm infants. The frequency of feeding problems remained markedly elevated when preterm HIV-exposed neonates were compared to preterm controls. Respiratory distress in near-term infants was seen in 13 % of the cases and 2.6 % of them had to be ventilated artificially. This was a higher frequency than in babies delivered by elective Caesarean section without maternal HIV history. Transmission prophylaxis in offspring of HIV-positive mothers may give rise to adverse effects. Their frequency is higher in preterm infants than in near-term infants. However; this may be related to prematurity, and not to the antiretroviral treatment itself.
