Abstract

Background. Cryptococcosis-associated immune reconstitution inflammatory syndrome (C-IRIS) may be driven by aberrant T-cell responses against cryptococci. We investigated this in human immunodeficiency virus (HIV)-infected patients with treated cryptococcal meningitis (CM) commencing combination antiretroviral therapy (cART).Methods. Mitogen-and cryptococcal mannoprotein (CMP)-activated (CD25+CD134+) CD4+ T cells and-induced production of interferon-gamma (IFN-γ), IL-10, and CXCL10 were assessed in whole blood cultures in a prospective study of 106 HIV-CM coinfected patients.Results. Patients with paradoxical C-IRIS (n = 27), compared with patients with no neurological deterioration (no ND; ..
