IRIS = immune reconstitution inflammatory syndrome.
Time interval is the period between diagnosis of histoplasmosis and IRIS.
Baseline was diagnosis of acquired immunodeficiency syndrome (AIDS). AIDS was detected by histoplasmosis for all patients except patients 1 and 2 for whom IRIS was the first manifestation of histoplasmosis. Patient 1 was treated with chemotherapy and highly active anti-retroviral therapy (HAART) for Kaposi's sarcoma. Histoplasmosis-related adenopathy appeared three months after onset of HAART, when chemotherapy was stopped. Patient 2 had AIDS-defining toxoplasmosis and onset of HAART three weeks before IRIS.
These two patients had an unplanned interruption of HAART and became compliant again 2 months before IRIS. No immunovirologic data were available during HAART interruption.
