Long term mortality and disability in Cryptococcal Meningitis: a systematic literature review.

Abstract

Cryptococcal meningitis (CM) is the primary cause of meningitis in HIV-infected adults and an emerging disease in HIV-seronegative individuals. No literature review has studied the long-term outcome of CM. We performed a systematic review on the long-term (≥3 months) impact of CM (C. neoformans and C. gattii) on mortality and disability in HIV-infected and non-HIV-infected adults. Though the quality of current evidence is limited, the long-term impact of CM on survival and disability appears to be high. One-year mortality ranged from 13% in an Australian non-HIV C.gattii infected cohort to 78% in a Malawian HIV-infected cohort treated with fluconazole monotherapy. One-year impairment proportions among survivors ranged from 19% in an Australian C.gattii cohort to more than 70% in a Taiwanese non-HIV and HIV-infected cohorts. Ongoing early therapeutic interventions, early detection of impairments and access to rehabilitation services may significantly improve patients' survival and quality of life.
