Indications to respiratory syncytial virus immunoprophylaxis in the 29-32 wGA group: Is there still room for debating?

Abstract

Guidelines on immunoprophylaxis for prevention of RSV infection recommend it in preterm babies born before 29 wGA; in babies affected by bronchopulmonary dysplasia or congenital heart defects; and in post-heart transplantation patients. On the contrary, immunoprophylaxis is not recommended in preterm babies born between 29 and 35 wGA. We evaluated the impact of RSV-related healthcare expenditures in infants in the first 3 years of life in Italy, Lombardy Region. In light of the collected data and considering the cost of a complete palivizumab prophylaxis, extending it to babies 29-32 wGA, aged less than 6 months, appears to be a cost-effective strategy.
