Methods |
Study type: unblinded RCT Setting: 8 hospitals in the USA and 5 hospitals in Thailand |
|
Participants |
Inclusion criteria: ≥ 13 years of age; positive CSF culture Exclusion criteria: pregnant or breastfeeding; prior cryptococcal meningitis; concomitant CNS illness that would interfere with assessment of response; creatinine clearance < 50 mL/min; ALT > 5 x ULN; coma; anticipated survival < 14 days; previous antifungal therapy > 3 days; untreated active tuberculosis Number randomized: 143 (8 excluded for negative CSF culture, withdrawal of consent before treatment, poor renal function, prior episode of cryptococcosis, or receipt of substantial antifungal therapy or rifampicin before study enrolment) Age: mean 37 years (AmBd); 36 years (AmBd and fluconazole 400 mg); 36 years (AmBd and fluconazole 800 mg) Gender: 65% male (AmBd); 65% male (AmBd and fluconazole 400 mg); 64% male (AmBd and fluconazole 800 mg) CD4 T‐cell count: median 18 cells/μL (AmBd); 17 cells/μL (AmBd and fluconazole 400 mg/day); 15 cells/μL (AmBd and fluconazole 800 mg/day) Baseline ART: 8% of participants on ART at baseline Baseline GCS/AMS: excluded if in coma |

Interventions |
Intervention
Consolidation: fluconazole 400 mg/day for 8 weeks in intervention 1 and intervention 2; fluconazole 800 mg/day for 8 weeks in intervention 3 Postdiagnosis ART: participants on baseline ART continued; investigators discouraged initiation of ART before 42 days; at day 42, 17% (AmBd), 4% (AmBd and fluconazole 400 mg/day), and 22% (AmBd and fluconazole 800 mg/day) had initiated ART. Lumbar puncture schedule: encouraged aggressive management of raised intracranial pressure with LP; scheduled on days 14 and, if still positive, repeated on days 42 or 70 Laboratory monitoring: monitoring schedule not specified |

Outcomes |
Primary outcomes
Secondary outcomes: none Outcome assessment schedule: participants evaluated regularly while hospitalized, then followed through 100 days. |

Notes |
Date of study: 2005 to 2007 Funding: National Institutes of Health (USA); fluconazole donated by Pfizer Declaration of conflict of interest by authors: Authors declared research support from several pharmaceutical companies including manufacturer of study drug. |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | 1:1:1 randomization via adaptive randomization system stratified by country and CSF opening pressures (≤ 250 mm versus > 250 mm) |
Allocation concealment (selection bias) | Unclear risk | Not specified |
Blinding of participants and personnel (performance bias) All outcomes | High risk | Unblinded |
Blinding of outcome assessment (detection bias) All outcomes | Low risk | Blinded data review committee adjudicated study data related to clinical and safety outcomes. |
Incomplete outcome data (attrition bias) All outcomes | Low risk | Outcomes reported for all participants. |
Selective reporting (reporting bias) | Low risk | Authors reported on all primary clinical and safety outcomes. |
Other bias | Unclear risk | Several authors received research support from pharmaceutical companies, including manufacturer of study drug. |
