title: Hemophagocytic Syndrome in the Setting of AIDS and Disseminated Histoplasmosis: Case Report and a Review of Literature.
abstract: Hemophagocytic lymphohistiocytosis (HLH) is traditionally regarded as a rapidly progressive and often fatal illness. In patients with AIDS, HLH usually occurs secondary to opportunistic infections. Although popular guidelines exist for the diagnosis and management of HLH in general, no formal study has evaluated their applicability among adult patients who develop HLH in the setting of AIDS and opportunistic infections. The study reports on a case of HLH in a patient with AIDS and disseminated histoplasmosis. Eighteen other previously reported cases of HLH in the setting of AIDS and histoplasmosis were reviewed. Majority of the cases occurred in patients with a CD4 count of less than 70 cells/mm(3). Overall mortality was 44%. Not getting antifungal treatment and having Histoplasma in blood were the 2 main risk factors for death. Among the patients who had a timely diagnosis of histoplasmosis and were initiated on antifungal therapy, the survival rates were significantly better, especially in the post-2000 ad period.
