Studies in homosexual patients with and without lymphadenopathy - Relationships to the acquired immune deficiency syndrome

We studied the immunologic function of 19 sexually active homosexual men, ten of whom had persistent lymphadenopathy. Analysis of mononuclear cell populations distinguished homosexuals from heterosexual controls since, as a group, homosexuals had increased percentages of natural killer cells (Leu 7+), decreased helper-inducer T lymphocytes (OKT-4+), increased suppressor/cytotoxic (OKT-8+) T lymphocytes, low OKT-4:OKT-8 ratios, and depressed mitogenic responses. Homosexuals without lymphadenopathy were distinguishable from controls by increased percentages of la+ cells, decreased OKT-4+ cells, and decreased OKT-4:OKT-8 ratios. Four had positive findings simultaneously for hepatitis B surface antigen (HBsAg) and surface antibody, and five had positive findings for HBsAg alone. Homosexuals with lymphadenopathy were distinguishable from controls by increased percentages of Leu 7+ cells, increased total lymphocyte numbers per cubic millimeter, decreased percentages of both OKT-4+ and OKT-8+ cells, abnormal OKT-4:OKT-8 ratios, and depressed mitogenic responses. Only histories of larger numbers of sexually acquired diseases, higher numbers of OKT-8+ cells per cubic millimeter, and lower mitogenic responses in homosexuals with lymphadenopathy distinguished this group from homosexuals without lymphadenopathy. Furthermore, none of the nine patients tested in this group was HBsAg positive. We conclude that homosexuals without lymphadenopathy are distinguishable from those with lymphadenopathy by both immunologic and serologic abnormalities

Kaposi's sarcoma with a non-Hodgkin's lymphoma. Its association in a male homosexual with human T-cell lymphotropic virus type III infection

Combined tumor syndromes, specifically reticuloendothelial malignancies and Kaposi’s sarcoma, have long been recognized. With the recognition of the acquired immunodeficiency syndrome (AIDS), several patients with concurrent non-Hodgkin’s lymphoma and Kaposi’s sarcoma have been reported at high risk for developing AIDS. The present Centers for Disease Control definition of AIDS excludes these patients on the assumption that one tumor is affecting the cellular immunity, allowing for the development of the second malignancy. In evaluating such a patient who had serologic evidence of human T-cell lymphotropic virus type III infection, the probable cause of AIDS, we have reviewed reports of patients with similar concurrent malignancies before and since the onset of the AIDS epidemic. We conclude that patients in high-risk groups for AIDS who develop similar combined tumor syndromes should be classified as having AIDS

Dermatologic manifestations of nontuberculous mycobacterial diseases

Various nontuberculous mycobacteria can cause infection of skin and soft tissues. These organisms are also known as atypical mycobacteria, anonymous mycobacteria, and mycobacteria other than tuberculosis. These organisms are much more common causes of cutaneous infection than Mycobacterium tuberculosis. Infections caused by nontuberculous mycobacteria are frequently misdiagnosed because clinicians fail to include them in the differential diagnosis of chronic skin infection
