[Disseminated mycobacteriosis with M. kansasii in a case of AIDS without HIV infection]. / Disseminierte Mykobakteriose mit M. kansasii bei einem Fall von Aids ohne HIV-Infektion.

M. kansasii is an environmental Mycobacterium that causes disease mainly in patients with local or systemic immunodeficiency. We present a case with disseminated M. kansasii infection which led to a severe febrile illness lasting for 9 months. The patient had a combined acquired immunodeficiency syndrome (AIDS) which included CD4+ and CD8+ T-lymphocytopenia, monocytopenia and a deficiency in the IgG subclasses 2 and 4. HIV testing was repeatedly negative. In the published literature only 4 of 10 similar patients (this patient included) survived a disseminated M. kansasii infection. Eleven years after the disseminated infection with M. kansasii a second opportunistic infection, disseminated mollusca contagiosa and hyperparathyroidism, developed, and 14 years later the immunologic abnormalities persist.
