Clinical Information
- A disease caused by human immunodeficiency virus (hiv). People with acquired immunodeficiency syndrome are at an increased risk for developing certain cancers and for infections that usually occur only in individuals with a weak immune system.
- 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. Symptoms include generalized lymphadenopathy, fever, weight loss, and chronic diarrhea. Patients with aids are especially susceptible to 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.
- 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.
- An infection caused by the human immunodeficiency virus.
- Any state of infection accompanied by evidence of hiv in the body (positive test for hiv genome, cdna, proteins, antigens, or antibodies); may be medically asymptomatic or symptomatic; use aids when appropriate.
- Includes the spectrum of human immunodeficiency virus infections that range from asymptomatic seropositivity, thru aids-related complex (arc), to acquired immunodeficiency syndrome (aids).
- One or more indicator diseases, depending on laboratory evidence of hiv infection (cdc); late phase of hiv infection characterized by marked suppression of immune function resulting in opportunistic infections, neoplasms, and other systemic symptoms (niaid).
