Background: Cryptococcal meningitis accounts for 15% of all AIDS mortality globally. Most cases in low- and middle-income countries are treated with fluconazole monotherapy, which is associated with a high mortality. New available therapies are needed. Short-course amphotericin B has been shown to be a safe and efficient therapeutic option. Sertraline has in vitro fungicidal activity against Cryptococcus and bi-directional synergy with fluconazole.
Methods: We conducted an open-label clinical trial to assess the safety and efficacy of sertraline 400 mg/day and fluconazole 1200 mg/day (n = 28) vs sertraline, fluconazole and additional 5 days of amphotericin B deoxycholate 0.7-1 mg/kg (n = 18) for cryptococcal meningitis.
Results: Two-week survival was 64% (18/28) without amphotericin and 89% (16/18) with amphotericin, and 10-week survival was 21% (6/28) vs 61% (11/18), respectively (P = .012). The cerebrospinal fluid (CSF) Cryptococcus clearance rate was 0.264 log10 colony-forming units (CFU)/mL of CSF/day (95% CI: 0.112-0.416) without amphotericin and 0.473 log10 CFU/mL/day (95% CI: 0.344-0.60) with short-course amphotericin (P = .03). Sertraline was discontinued in one participant due to side effects. Four participants receiving amphotericin B experienced hypokalemia <2.4 mEq/L.
Conclusions: Short-course amphotericin substantially increased CSF clearance and 10-week survival. Adjunctive sertraline improved 2-week CSF fungal clearance but did not improve 10-week mortality compared with published data using fluconazole 1200 mg/day monotherapy (early fungicidal activity 0.15 log10 CFU/mL/day).
