Virus recovery from stools of patients undergoing bone marrow transplantation.
Diarrhea in marrow transplant recipients is a frequent complication attributable to non-infectious events such as acute GVHD or infectious events such as viral gastroenteritis. Rotavirus and enteric adenovirus are the most frequent viral pathogens. To determine the frequency of these infections, we prospectively examined the stool specimens of 94 patients who underwent autologous BMT (34 cases) or allogeneic BMT (60 cases). Stool specimens were examined from patients twice weekly. Nineteen of the 94 patients were infected with viral pathogens. This study showed: (1) an incidence of viral gastroenteritis identical in autologous and allogeneic BMT (20%), (2) a persistent risk despite treatment in laminar air flow rooms, (3) a significant association with severe acute GVHD, and (4) a significant risk of multiple viral infections in autologous BMT recipients. Rotavirus and adenovirus are a cause of enteritis involvement in patients undergoing BMT and they may be underdiagnosed and confused with GVHD. Screening of stool specimens after BMT should be directed to prevention and treatment of these viral infections to decrease the morbidity and mortality associated with BMT.
