 Human immunodeficiency virus (hiv) disease- A prodromal phase of infection with the human immunodeficiency virus (HIV). Laboratory criteria separating AIDS-related complex (ARC) from AIDS include elevated or hyperactive B-cell humoral immune responses, compared to depressed or normal antibody reactivity in AIDS; follicular or mixed hyperplasia in ARC lymph nodes, leading to lymphocyte degeneration and depletion more typical of AIDS; evolving succession of histopathological lesions such as localization of Kaposi's sarcoma, signaling the transition to the full-blown AIDS.
- A syndrome resulting from the acquired deficiency of cellular immunity caused by the human immunodeficiency virus (HIV). It is characterized by the reduction of the Helper T-lymphocytes in the peripheral blood and the lymph nodes; opportunistic infections (usually pneumocystis carinii pneumonia, cytomegalovirus (CMV) infections, tuberculosis, candida infections, and cryptococcosis); and the development of malignant neoplasms (usually non-Hodgkin's lymphoma and Kaposi's sarcoma). The human immunodeficiency virus is transmitted through sexual contact, sharing of contaminated needles, or transfusion of contaminated blood. Generalized lymphadenopathy, fever, weight loss, and chronic diarrhea are common symptoms of AIDS. The patients usually die either of opportunistic infections or malignant neoplasms. -- 2004
- An acquired defect in immune system function caused by human immunodeficiency virus (HIV). AIDS is associated with increased susceptibility to certain cancers and to opportunistic infections, which are infections that occur rarely except in individuals with weak immune systems.
- An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.
- Includes the spectrum of human immunodeficiency virus infections that range from asymptomatic seropositivity, thru AIDS-related complex (ARC), to acquired immunodeficiency syndrome (AIDS).
