Cryptococcal meningitis in non-HIV-infected patients in a Chinese tertiary care hospital, 1997-2007

Information remains sparse about non-HIV patients with cryptococcal meningitis in the era of triazole therapy. Particularly of interest are the clinical manifestations and prognosis of the infection in these previously healthy patients. We retrospectively reviewed 154 non-HIV-infected patients with cryptococcal meningitis who presented in our hospital from 1997 to 2007. We compared the clinical features and outcomes between predisposed and otherwise healthy hosts. The number of cases per year showed a steady increase over time. The majority of patients were otherwise apparently healthy (103 patients, 66.9%) and predisposing factors were identified in only 51 (33.1%) patients. Corticosteroid medication accounted for the most common underlying factor in these cases (n = 21). Morbidity was appallingly high, with seizures in 28.6%, cranial nerves palsies in 51.5% and cerebral herniation in 19.5%. Despite these complications, overall mortality during 1 year was 28.7% (41/143), close to that reported from other centers with non-HIV patients. Death attributed to cryptococcosis occurred in 19.6% (28/143) patients with most receiving amphotericin B as a component of their initial therapy. Among surviving patients who had lumbar punctures at weeks 2 and 10, those given amphotericin B for initial therapy achieved higher rates of overall response than those receiving initial fluconazole therapy at either week 2 (84.4% of 96 patients vs. 33.3% of 24 patients, P
