Postinfectious inflammatory response syndrome in HIV-uninfected and nontransplant men after cryptococcal meningitis

Abstract

Aim: The aim of our study was to describe the characteristics of postinfectious inflammatory response syndrome (PIIRS) in HIV-uninfected and nontransplant men after cryptococcal meningitis (CM). Patients & methods: A case-control study was designed to compare HIV-uninfected and nontransplant male CM patients with and without PIIRS. Results: CM-PIIRS patients had increased rates of hearing loss, V-P shunt placement, amphotericin B treatment, higher cerebrospinal fluid pressures and Cryptococcus counts in the first CM episode. CM-PIIRS episode was characterized by higher frequencies of headache and fever, higher C-reactive protein, erythrocyte sedimentation rate, cerebrospinal fluid white blood cell (WBC) counts and modified Rankin Score. Brain MRI scans revealed the high signal lesions on axial flair imaging. Receipt of corticosteroid therapy was associated with lower rates of fever and better modified Rankin Score scores at 1 month after treatment. Conclusion: CM-PIIRS episode differs to the initial presentation, may help to identify which patients are at risk to develop PIIRS. Steroids therapy could be beneficial.
