| Abstract | |
Respiratory viruses can cause significant morbidity in immunocompromised hosts. Human metapneumovirus (hMPV) has been increasingly associated with lower respiratory tract infection in hematopoietic SCT (HSCT) recipients, with mortality rates up to 50%. No data on the occurrence of hMPV infection in HSCT recipients have been reported in the southern hemisphere. We conducted a retrospective study including 228 nasal wash samples from 153 HSCT recipients with respiratory symptoms during 2001, 2002 and 2003. hMPV was detected by real-time PCR with primers complementary to the nucleocapsid region of hMPV genome. Eleven of the 153 patients (7.2%) acquired hMPV infection during the study period (6.4% in 2001, 4.7% in 2002 and 11.1% in 2003). Among the 11 HSCT recipients with hMPV infection, 1 died 8 days after the diagnosis, but the role of hMPV in the patient's death could not be established. In 2001 and 2003, hMPV group A prevailed over group B. In 2002, both groups were detected equally. hMPV infections were diagnosed in late winter and spring. The frequency of hMPV infection in HSCT recipients living in Brazil was similar to those observed in the northern hemisphere. Sensitive techniques to detect hMPV should be included in the diagnostic assessment of HSCT recipients with respiratory symptoms. (AU) | |
