Yield of bone marrow culture in the diagnosis of infectious diseases in patients with acquired immunodeficiency syndrome

Abstract

The yield in cultures of bone marrow aspirations or biopsies was determined in 50 patients with acquired immunodeficiency syndrome. Most patients were febrile and had no identifiable source of infection. Concurrent stool, urine, and blood samples were also cultured. The bone marrow aspiration and biopsy procedures produced no complications and enabled a microbiological diagnosis to be made in 42% of the cases. Granuloma formation was not seen in any of the infected bone marrow specimens despite the fact that mycobacteria were seen in abundance in some. Bone marrow culture is a valuable low-morbidity invasive procedure in the evaluation of febrile patients with acquired immunodeficiency syndrome.
