Respiratory virus infections in pediatric hematopoietic stem cell transplantation.
Respiratory virus infections (RVI) have become an increasingly appreciated problem in the hematopoietic stem cell transplant (HSCT) population. A retrospective analysis of 274 patients undergoing 281 HSCT at St. Jude Children's Research Hospital from January 1994 through December 1997 was performed. Medical and clinical laboratory records were reviewed beginning at the onset of conditioning through the year following each HSCT, and the analysis was done for the first RVI only. Thirty-two (11%) of 281 HSCT cases developed a RVI during the first year post-HSCT. The most frequent cause of RVI was human parainfluenza virus type 3. Univariate analysis was performed to determine the association between risk factors and the cumulative incidence of RVI. Respiratory viruses are frequent causes of infections in the first year post-HSCT in the pediatric population. Only allogeneic transplant and the degree of acute or chronic graft versus host disease were found to be statistically significant risk factors for RVI.
