BackgroundCryptococcal meningitis is a leading cause of death among HIV‐infected individuals in sub‐Saharan Africa. Recent developments include the availability of intravenous fluconazole, cryptococcal antigen assays and new data to support fluconazole pre‐emptive treatment. In this study, we describe the impact of screening HIV‐positive adult inpatients with serum cryptococcal antigen (CRAG) at a Tanzanian referral hospital.MethodsAll adults admitted to the medical ward of Bugando Medical Centre are counseled and tested for HIV. In this prospective cohort study, we consecutively enrolled HIV‐positive patients admitted between September 2009 and January 2010. All patients were interviewed, examined and screened with serum CRAG. Patients with positive serum CRAG or signs of meningitis underwent lumbar puncture. Patients were managed according to standard World Health Organization treatment guidelines. Discharge diagnoses and in‐hospital mortality were recorded.ResultsOf 333 HIV‐infected adults enrolled in our study, 15 (4.4%) had confirmed cryptococcal meningitis and 10 of these 15 (66%) died. All patients with cryptococcal meningitis had at least two of four classic symptoms and signs of meningitis: fever, headache, neck stiffness and altered mental status. Cryptococcal meningitis accounted for a quarter of all in‐hospital deaths.ConclusionsDespite screening of all HIV‐positive adult inpatients with the serum CRAG at the time of admission and prompt treatment with high‐dose intravenous fluconazole in those with confirmed cryptococcal meningitis, the in‐hospital mortality rate remained unacceptably high. Improved strategies for earlier diagnosis and treatment of HIV, implementation of fluconazole pre‐emptive treatment for high‐risk patients and acquisition of better resources for treatment of cryptococcal meningitis are needed.

IntroductionAdolescents account for over 40% of new HIV infections in Haiti. This analysis compares outcomes among HIV‐positive adolescents before and after implementation of an adolescent HIV clinic in Port‐au‐Prince, Haiti.MethodsWe conducted a cohort study using programmatic data among HIV‐positive adolescents aged 13 to 19. Data from 41,218 adolescents who were HIV tested from January 2003 to December 2012 were included. Outcomes across the HIV care cascade were assessed before and after implementation of an adolescent clinic (2009), including HIV testing, enrolment in care, assessment for antiretroviral therapy (ART) eligibility, ART initiation and 12‐month retention. Pre‐ART outcomes were assessed 12 months after HIV testing. Factors associated with pre‐ART and ART attrition were identified through multivariable competing risk and Cox proportional hazards regression modelling.ResultsCumulatively, 1672 (4.1%) adolescents tested HIV positive (80% female, median age 16 years). Retention by cascade step comparing pre‐ and post‐clinic included the following: 86% versus 87% of patients enrolled in care, 61% versus 79% were assessed for ART eligibility, 85% versus 92% initiated ART and 68% versus 66% were retained 12 months after ART initiation. Pre‐ART attrition decreased from 61% pre‐clinic to 50% post‐clinic (p<0.001). Pre‐ART attrition was associated with being female (sub‐distributional hazard ratio (sHR): 1.59; CI: 1.31–1.93), syphilis diagnosis (sHR: 1.47; CI: 1.16–1.85) and slum residence (sHR: 0.84; CI: 0.72–0.97). ART attrition was associated with syphilis diagnosis (hazard ratio (HR): 2.23; CI: 1.35–3.68) and CD4 <50 cells/µL (HR: 1.88; CI: 1.15–3.06).ConclusionsImplementation of a youth‐friendly adolescent clinic improved retention in HIV care among adolescents, particularly in the assessment of ART eligibility and ART initiation. Additional interventions are needed to improve retention among pre‐ART patients and support long‐term retention among ART patients.
