Profilaxis de infección por virus respiratorios en niños y adultos sometidos a trasplante de órganos sólidos y precursores hematopoyéticos

Abstract

Respiratory viruses have been identified as a cause of morbidity and mortality in patients undergoing SOT and HSCT, specially in children. The most frequent are respiratory syncytial virus (RSV), influenza (FLU), parainfluenza (PI) and adenovirus (ADV). These infections are associated with progression to severe lower respiratory tract infections in up to 60% of the cases. It is advised to apply universal protection recommendations for respiratory viruses (A2) and some specific measures for FLU and AD. FLU: Annual anti-influenza vaccination (from 4-6 months post-transplantation in SOT, 6 months in HSCT (A2)); post- exposure prophylaxis in FLU (oseltamivir for 10 days (B2)). In lung transplantion, the prophylaxis should last as long as the risk period (B2). ADV: There is no vaccine nor valid chemoprophylaxis strategy to prevent ADV disease. In some specific HSCT recipients, weekly PCR monitoring is recommended until day+100 (A3).
