In 4 years (1984-1987), 183 bone marrow examinations were performed on 155 human immunodeficiency virus (HIV) antibody positive patients. One hundred and fifty three had category IV AIDS. One-third of the marrows yielded specific information. This included opportunistic infection, in particular Mycobacterium Avium Intracellulare Complex (MAI) (24%), malignancy (4%), consistent with ITP (9%) and iron deficiency (1%). In the remaining two thirds of the bone marrows the most frequent non-specific abnormalities were dyserythropoiesis, erythroid hypoplasia, reticuloendothelial iron block, granulomas, lymphoid aggregates, plasmacytosis and histiocytosis. Common peripheral blood findings were anemia, lymphopenia, anisocytosis, rouleaux and atypical lymphocytes. Peripheral blood and bone marrow examinations on 16 patients on AZT are included. These patients have more pronounced blood and bone marrow abnormalities. The causes of these abnormalities are multifactorial and include low T4 levels, severe viral and other infections and therapy with marrow toxic drugs.

Between February 1983 and April 1986 we studied peripheral blood and bone marrow samples from 20 patients with human immunodeficiency virus (HIV) related disease. 14 patients had AIDS, three had ARC, two had PGL and one had ITP as a sole manifestation of HIV related disease. Peripheral blood abnormalities included marked anisocytosis and poikilocytosis, rouleaux formation, neutropenia, lymphopenia, monocytopenia, a left shift in the granulocyte series and, in the patients with AIDS, vacuolated monocytes. The most frequent bone marrow abnormalities were reticuloendothelial iron block, dyserythropoiesis, megaloblastic change and erythroid hypoplasia. Excess histiocytes were noted in four marrows, one exhibiting haemophagocytosis. None of the bone marrows showed lymphopenia. Eight of the 20 marrows were difficult or impossible to aspirate. None of the trephine biopsies showed increased reticulin. The causes of these abnormalities are probably multiple and include opportunistic infections, drug therapy, immune mechanisms and possibly direct insult by the HIV virus.
