title: Acquired immunodeficiency syndrome with Pneumocystis carinii pneumonia and Mycobacterium avium-intracellulare infection in a previously healthy patient with classic hemophilia. Clinical, immunologic, and virologic findings.
abstract: A previously healthy patient with classic hemophilia who was on a home infusion program with factor VIII concentrates developed an acquired immunodeficiency syndrome manifested by a dramatic weight loss (47 kg over 12 months), lassitude, transient thrombocytopenia, and opportunistic infections with Varicella zoster, Pneumocystis carinii, and Mycobacterium avium-intracellulare. The patient was not homosexual and had no history of intravenous drug abuse. Immunologic studies showed a persistent lymphopenia with reversal of helper/suppressor-cytotoxic T-lymphocyte ratios, depression of human natural killer cell function, and in-vitro lymphocyte proliferative responses to mitogens and viral antigens. Serum IgA levels were also elevated. Serum antibodies against cytomegalovirus, herpes simplex viruses 1 and 2, Epstein-Barr virus, Varicella zoster, and hepatitis B virus were shown, suggesting previous infection by these agents. Reactivation of cytomegalovirus infection was suggested by a rising titer of antibodies against cytomegalovirus concurrent with pneumocystis pneumonia, and was confirmed by the growth of this virus in a throat culture 2 months later.
