title: Respiratory disease due to parainfluenza virus in adult leukemia patients.
abstract: Reports of human parainfluenza viruses (HPIV) in patients with leukemia have been limited to a few cases or as a portion of general surveys. In order to expand the knowledge of these infections in this patient group, the frequency and clinical course of HPIV infections was determined among 1,787 patients with leukemia treated at The University of Texas M.D. Anderson Cancer Center between July 1994 and December 1997. HPIV was isolated from 47 (6.2%) of the 770 patients who were cultured for respiratory viruses. HPIV type 3 accounted for 39 of the 47 HPIV infections. Twenty-six patients developed pneumonia, and the associated mortality was 27%. Multivariate analysis revealed that a low absolute lymphocyte count and pneumonia were associated with increased mortality. Concurrent respiratory and other infections were associated with an increased frequency of pneumonia. Only five patients with pneumonia received antiviral therapy and four of them survived the infection. HPIV infection in leukemic patients is frequently associated with pneumonia and the mortality rate from pneumonia is substantial among lymphopenic patients.
