gattii meningitis in Egypt: a case report. View/ Open. Immune reconstitution inflammatory syndrome (IRIS) is a well described complication of effective treatment for CNS cryptococcosis, leading to an increased risk for morbidity and mortality secondary to increased intracranial pressure (ICP) [1, 2]. Corticosteroids are often used as an adjunct to antifungal therapy for treatment of IRIS . Cryptococcus-associated immune reconstitution inflammatory syndrome (C-IRIS) is identified upon immune reconstitution in immunocompromised patients, who have previously contracted an infection of Cryptococcus neoformans (Cn). C-IRIS can be lethal but how the immune system triggers life-threatening outcomes in patients is still poorly understood.

The risk of IRIS appears to be much lower with other forms of cryptococcosis; IRIS may present as lymphadenitis, cutaneous abscesses, or bony lesions. 39 Management is similar to that for IRIS associated with cryptococcal meningitis, including continuing ART, initiating or continuing antifungal therapy (AIII), and considering glucocorticoids (CIII). Background: Cryptococcal meningitis remains the leading cause of adult meningitis in Sub-Saharan Africa. Immune Reconstitution Inflammatory Syndrome (IRIS) following anti-retroviral therapy (ART) initiation is an important complication.

Abstract This review provides an overview of Cryptococcus neoformans immunology and focuses on the pathogenesis of Cryptococcus-related paradoxical immune reconstitution inflammatory syndrome (IRIS).

Sep 15, 2009 · The overall incidence of cryptococcal IRIS was 47 cases per 100 person-years (95% confidence interval [CI], 25-80 cases per 100 person-years). The median interval from HAART initiation to diagnosis of IRIS was 63 days (range, 12-129 days). Headache was the most common symptom, reported in 8 (61.5%) of the 13 patients. Sep 05, 2007 · The cryptococcal IRIS developed between three and 27 months after antiretroviral therapy was initiated, and the investigators could not identify any factors to identify which patients were at particular risk, nor predict when the IRIS might occur.

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). Cryptococcus-associated immune reconstitution inflammatory syndrome (C-IRIS) is identified upon immune reconstitution in immunocompromised patients, who have previously contracted an infection of Cryptococcus neoformans (Cn). C-IRIS can be lethal but how the immune system triggers life-threatening outcomes in patients is still poorly understood.

Immune reconstitution inflammatory syndrome (IRIS) presents as an exaggerated immune reaction that occurs during dysregulated immune restoration in immunocompromised patients in late-stage human immunodeficiency virus (HIV) infection who have commenced antiretroviral treatments (ART). Virtually any opportunistic pathogen can provoke this type of immune restoration disorder.
