Infections in haematological malignancies: An autopsy study of 72 cases

Autopsy material from 72 patients with haematological malignancies treated in India was reviewed. Thirty-seven patients (51%) had documented infections; 20 (27%) had bacterial infections, 14 of which were Gram-negative organisms (Pseudomonas species in 10); tuberculosis was present in 2 patients (2.7%). Twenty-one patients (29%) had systemic fungal infections; invasive pulmonary aspergillosis and gastrointestinal candidiasis were present in 10 patients each. Only 3 patients (4%) had viral infection, all of which were due to cytomegalovirus. Eleven patients (15%) had polymicrobial infections. No patient had any parasitic infection. Systemic fungal infections due to Aspergillus and Candida predominated, while Gram-negative bacterial infections were also common.
