To the Editor.—Abnormalities in cellular immune responses in patients with human immunodeficiency virus (HIV) infection have been shown to increase with the stage of diseases.^1-3 The report by Murray et al⁴ in the July 1988 issue of the ARCHIVES of cytomegalovirus (CMV) and toxoplasma antigen–induced interferon gamma responses in laboratory (not shown) and homosexual control subjects and patients with HIV-related diseases clarifies observed differences between subsets of these conditions. In addition, mean counts of peripheral blood CD4 positive (T4⁺, Leu3⁺, and T-helper/inducer type) cells were again shown to be decreased in more advanced stages of disease. A direct correlation of these cell counts with the immune responses was not shown.

Having performed studies of immune responses to herpesvirus antigens in seropositive, HIV-positive patients from all disease stages, we have coincidently examined peripheral blood CD4⁺ cell counts. Peripheral blood mononuclear cell transformation indexes were performed by culture of . . . [Full Text PDF of this Article]
