Revisited indications for bone marrow examinations in HIV-infected patients.
We reviewed the indications for and the results of bone marrow examination (BME) from HIV-infected patients as an attempt to improve its diagnostic yield. One-hundred-and-eight bone marrow specimens from 90 patients during a 3-year period were examined. A cytological, histological and microbiological study was carried out on the specimens. Forty-three evaluable examinations (40% of total) performed for cytopenia showed normo- or hypercellularity in 33 (77%). Fifty bone marrow specimens were cultured for mycobacteria with a yield of 42% when the indication was persistent fever. Positive cultures yielded Mycobacterium avium complex in 8 out of 12 patients. Twenty-seven patients had both culture and biopsy; granulomas were associated with all the positive (10/10) and with 1 out of 17 negative cultures (chi-square test: p < 0.001). A bone marrow involvement with lymphoma was found in 2 out of 6 patients with previously diagnosed lymphoma, and biopsy revealed a lymphoma in 2 patients. Morphological bone marrow examination should be associated with other techniques in order to appreciate bone marrow production. Bone marrow biopsy is useful for the investigation of persistent fever since granulomas suggestive of disseminated mycobacteria are frequent and allow a treatment to be initiated before microbiological confirmation and antibiotic susceptibility test.
