Respiratory syncytial virus infections in pediatric liver transplant recipients.

Respiratory syncytial virus (RSV) is the most important cause of lower respiratory tract infection in infants and young children. The charts of 17 children found to have RSV among 493 children who underwent liver transplantation between February 1985 and February 1991 were reviewed. The median age at diagnosis was 20 months. Median time of diagnosis was 24 days after transplantation. Thirteen patients developed nosocomial infections while convalescing from their transplant. Common symptoms included tachypnea, cough, fever, and congestion. Acute radiographic changes were seen in 12 patients. Two deaths were associated with progressive pulmonary disease and occurred in children with infection early in the postoperative period who were intubated before the onset of symptoms. RSV in children after liver transplantation has a clinical spectrum similar to that in normal children. Early onset of infection (less than 20 days) after transplantation and preexisting lung disease may predict more severe disease.
