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. AIDS related complex AIDS-related complex (ARC) is mostly a historical artifact of the earlier stages of the AIDS epidemic. Revised CDC criteria in the 1980s led to many with symptomatic HIV infections and disease symptoms without an official diagnosis. ARC was created as a category for these persons. However, these persons would mostly be recategorized as having AIDS later. ARC acquired immunodeficiency syndrome-related complex The Complete Dictionary of Sexology
