Objective: To study survival time and risk factors of mortality among HIV-infected patients who had cryptococcal meningitis.
Design: Retrospective cohort study.
Material and Method: Patients’ medical records of those who had HIV-infection with newly diagnosed cryptoccocal meningitis between January 2002 and December 2004 were reviewed. Each patient was classified into one of two groups, according to their anti-retroviral status (ART).
Results: Five hundred and forty nine patients enrolled in the present study: 281 (51.2%) in the ART+ group and 268 (48.8%) in the ART-group. The mean age was 33.4 + 6.9 years old in the ART + group and 33.6 + 7.0 years old in the ART-group. There were more male in both groups: 207 males and 74 females in the ART+ group, and 195 males and 73 females in the ART-group. Baseline CD4 cell count of both groups was 20 (6-74) cells/ mL and 24 (9-72) cells/ ml. About 30% of both groups of patients experienced major opportunistic infection before cryptococcal meningitis. All patients were treated by standard amphotericin B for a 2-week duration followed by fluconazole for an additional 8 weeks. There were no differences of baseline characteristics between the two groups (p > 0.05). The survival rates at 12, 24, and 36 months were 92.8%, 87.4%, and 85.4% in the ART+ group and 55.3%, 42.2%, and 36.8% in the ART– group, respectively (p < 0.01). The median survival time in the ART- group was 15 months. From the Cox regression model, the hazard ratio for “not received ART” was 4.87 (95%CI = 2.48-9.44, p < 0.01).
Conclusion: The present study demonstrated the substantial increasing of survival time of HIV-infected patients with cryptococcal meningitis by initiated ART, even in a resource limited setting (no flucytosine, local combined antiretroviral drugs with NVP based regimens).
