Immune reconstitution syndromes in human immuno-deficiency virus infection following effective antiretroviral therapy

Abstract

Effective antiretroviral therapy leads to rapid decrease in plasma HIV-1 RNA, frequently followed by an increase in CD4 T-helper cell counts. The improvement of immune function during highly active antiretroviral therapy has important impact on natural history of AIDS-related opportunistic disorders. Here we describe cases of unusual clinical inflammatory syndromes in CMV retinitis, hepatitis C, and atypical mycobacteriosis in HIV-1 infected patients associated with the initiation of antiretroviral therapy. Pathogenetic implications and therapeutic management of these new immunopathologic syndromes are discussed.
