Infections are a major cause of morbidity and mortality in patients undergoing high-dose therapy and allogeneic bone marrow transplantation (BMT) despite prophylaxis, use of growth factors and newer antimicrobial drugs. We report the clinical profile of infections among 297 patients who underwent 304 allogeneic transplants between 1986 and December 2001. All patients developed febrile neutropenia. There were 415 documented infections among 304 transplants. This included bacterial (34.9%), viral (42.9%), fungal (15.9%) and other infections (6.3%) including tuberculosis. Bacterial pathogens were mainly Gram-negative bacteria (80%) as compared to Gram-positive (20%) bacteria. The common Gram-negative bacteria were nonfermenting Gram-negative bacteria (NFGNB) (24.9%), Pseudomonas (17.9%), Escherichia coli (17.9%) and Klebsiella (9.7%). The major source of positive cultures was blood (53.7%) followed by urine (25.5%) and sputum (8.9%). In all, 133/304 (43.7%) transplants had 178 documented viral infections. The common viral infections were due to cytomegalovirus, herpes group of viruses and transfusion-related hepatitis; and 60/304 (19.7%) transplants had 66 documented fungal infections. Common fungi included Aspergillus species (69.7%), Candida (22.2%) and Zygomycetes (8.1%). Tuberculosis was documented in 2.3% of the transplants. Catheter infections were suspected or documented in 7.8% of the transplants (24/304). The incidence of infections in this series from developing countries is not significantly different from reports from the West.
