dc.description.abstract | Respiratory syncytial virus (RSV) is the main cause of lower respiratory disease in infants and children under five years of age. As there is no specific treatment for RSV infections, prophylaxis with the specific monoclonal antibody palivizumab (PVZ) has been widely recommended for high-risk cases during the RSV season. The present study aimed to evaluate the effectiveness of a public prophylaxis program with palivizumab on the incidence of hospitalizations for lower respiratory tract infections and RSV in children at high risk for severe RSV infections. A retrospective cohort study was carried out with preterm children or children under two years of age with chronic lung disease or hemodynamically significant congenital heart disease; the children were selected on the basis of their exposure status, which was defined as the prophylactic use of palivizumab during the RSV season. Children were enrolled retrospectively in two hospitals located in Southern Brazil, from May 2009 to August 2016. In a sample of 129 children, 69 (53.5%) received palivizumab and adherence to three or more doses was observed in 78%; 60 (46.5%) children did not receive palivizumab. PVZ prophylaxis was independently associated with a 66% reduction in hospitalizations for any cause (26/69 - 37.7%) in the PVZ group and 34/60 (56.7%) in the control group). A 52% reduction in hospitalizations due to lower respiratory tract infection was observed in the PVZ group (15/69 -21.7%) and 25/60 (41.7%) in the control group. These findings suggest that, for the group of studied patients, the adoption of an RSV prophylaxis scheme reached the same effectiveness as those described in previous clinical trials. | en |
