[Atypical mycobacteria. Disseminated infection in patients with hematologic diseases].
During the last decade interest in atypical mycobacteria (AM), especially Mycobacterium avium complex (MAC) has been intense, as a large number of AIDS patients develop disseminated infection with MAC. Disseminated infection has also been reported in other immunocompromised patients, but in much fewer cases. Among haematological diseases hairy cell leukemia (HCL) and chronic myelogenous leukemia (CML) seem to predispose to disseminated AM infection. We review 53 cases of disseminated AM infection in haematological patients reported in the literature, 39 with HCL, ten CML, and four other haematological diseases, and a review of possible treatment is given. The prognosis seems to depend on the course of the underlying haematological disease, and we conclude that early diagnosis and treatment of the infection is of great importance. Blood and bone marrow should therefore be cultivated for mycobacteria in such patients with persistent fever of unknown cause, and in cases with negative cultures and elevated serum values of alkaline phosphatase liver biopsy should be considered.
