Abstract:Objective To investigate the morphological characteristics of bone marrow cells in patients with acquired immunodeficiency syndrome (AIDS), and to provide a clinical basis for the rapid diagnosis of AIDS and the prognosis. Methods The suspected cases of AIDS who underwent HIV examination were retrospectively analyzed. Among them, HIV positive patients were given bone marrow cytology examination, and the results of the examination were statistically analyzed. Results Totally 60 samples were taken and the satisfaction rate was 100%. Penicillium marneffei (PM) was detected in 8 cases, and lymphoma cells was detected in 1 case. There were 57 cases who were active in nucleated cells. Erythrocyte ratio increased in 27 cases, decreased in 26 cases. The first three common abnormal phenotypes of bone marrow cells were lymphocytopenia, abnormal morphology of erythrocyte nucleus and money-like arrangement of erythrocyte. At the end of the follow-up period, there were 27 deaths in 60 HIV-positive patients, with a total survival rate of 45.0% and a mortality rate of 11.67% in hypertrophic active patients, which was much lower than that in hypertrophic inactive patients (P?0.05). Conclusions The bone marrow cytology of aids patients is mainly characterized by granulocyte, red blood cell, megakaryocyte system, or multi-lineage hematopoietic, lymphocyte ratio is reduced, often accompanied by tissue cell reactive proliferation or activation, bone marrow cell detection can be used for aids patients screening.
