MeSH definition : 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.;
MeSH synonym : arc; lymphadenopathy syndromes; complex, aids-related; lymphadenopathy syndrome; syndrome, lymphadenopathy; syndromes, lymphadenopathy; AIDS related complex;
MeSH annotation : coord IM with HIV-1 or HIV-2 (IM) if pertinent; DF: note short X ref; coordinate with HIV-1 or HIV-2 if pertinent;
