HIV-associated thrombocytopenia: in vitro megakaryocyte colony formation in 10 patients

J F Abgrall et al. Ann Med Interne (Paris). 1992.

Abstract

In vitro bone-marrow megakaryocyte colony formation was studied in 10 patients with HIV-associated thrombocytopenia to investigate the mechanism of thrombocytopenia. Increased colony formation was observed in 3 patients and decreased growth in 7 patients. No relationship was noted between the growth potential of megakaryocyte progenitors and platelet count, number of CD4+ celts, platelet response to azidothymidine, and platelet count 7 days after culture. In all patients, megakaryocyte morphology was abnormal: blebbing of the membrane and abnormal chromatin with separated lobes of nuclei. Further studies are needed to determine if growth potential of megakaryocyte progenitors is useful in understanding the mechanism of thrombocytopenia in HIV-infected individuals.
