Abstract

The pathophysiology of meningitis caused by Cryptococcus gattii in apparently immunocompetent individuals remains unclear. We measured multiple cytokines in CSF from a HIV-seronegative, apparently immunocompetent, Thai patient with C. gattii meningitis, over the first 2 weeks of antifungal therapy. Levels of proinflammatory IFN-γ, TNF-α, and IL-6 were very low compared to patients with HIV-related Cryptococcus neoformans meningitis and of IL-10 very high. While patients with C. gattii meningitis may be a heterogeneous group, these data suggest in this case a maladapted immune response to cryptococcal exposure had allowed progression to clinical cryptococcal disease.
