  • Untitled AIDS 12
    1. Untitled acquired immunodeficiency syndrome (AIDS) . An acquired defect in immune system function caused by Untitled Human Immunodeficiency Virus (HIV) 1 (HIV-1). Untitled 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.
    2. Acquired Immune Deficiency Syndrome (AIDS): SFAF
      the late stage of HIV disease. AIDS involves the loss of function of the immune system as CD4 cells are infected and destroyed, allowing the body to succumb to opportunistic infections (e.g., Pneumocystis carinii pneumonia, toxoplasmosis) that are generally not pathogenic in people with intact immune systems. Common symptoms of AIDS include malignancies and wasting syndrome. The CDC defines AIDS as the presence of at least one of several opportunistic infections or the presence of fewer than 200 CD4 cells/mm3 in an HIV positive individual.

    3. acquired immunodeficiency syndrome (AIDS) JAMA
      The most severe manifestation of infection with the Human Immunodeficiency Virus (HIV). The Centers for Disease Control and Prevention (CDC) (see) lists numerous opportunistic infections and neoplasms (cancers) that, in the presence of HIV infection, constitute an AIDS diagnosis. There are also instances of presumptive diagnoses when a person's HIV status is unknown or not sought. This was especially true before 1985 when there was no HIV-antibody test. In 1993, CDC expanded the criteria for an AIDS diagnosis to include CD4+ (see) T cell count at or below 200 cells per microliter in the presence of HIV infection. In persons (age 5 and older) with normally functioning immune systems, CD4+ T cell counts usually range from 500 to 1,500 cells per microliter. Persons living with AIDS often have infections of the lungs, brain, eyes, and other organs, and frequently suffer debilitating weight loss, diarrhea (see), and a type of cancer called Kaposi's Sarcoma (see). See HIV Disease; Opportunistic Infection; Wasting Syndrome.
