- Registration Number
- NCT02334670
- Lead Sponsor
- National Hospital for Tropical Diseases, Hanoi, Vietnam
- Brief Summary
It is hypothesized that implementing plasma CrAg screening in clinics providing routine HIV care will enable identification of Vietnamese adult patients with advanced HIV (CD4 ≤100 cells/μL) who have early cryptococcal disease, enable prompt preemptive treatment with high-dose fluconazole, and improve survival.
- Detailed Description
This is multicenter prospective cohort evaluation of the implementation of a cryptococcal antigen (CrAg) screening program in Vietnam. HIV-infected patients with CD4 ≤100 cells/μL who present for HIV care at outpatient clinics (OPCs) in Vietnam where CrAg screening is offered will be recruited into the study. Study participants will be screened for cryptococcal antigen using the Lateral Flow Assay (LFA) and followed up for 12 months with clinical assessments and the collection of routine and supplemental survey data. Those who are CrAg-positive, but have no features of central nervous system (CNS) disease, will be treated with high-dose fluconazole. Those with symptoms of CNS disease will be treated according to national guidelines. Survival, retention in care, and other clinical outcomes will be documented for patients who test CrAg-positive and are treated with fluconazole and those who test CrAg-negative.

Group Intervention Description CrAg(+) and CM(+) Fluconazole Patients with symptoms of CNS disease will be treated according to Vietnam national guidelines for HIV/AIDS management. CrAg(+) and CM(-) Fluconazole Patients with CrAg(+) and without CM symptoms will be treated with high-dose fluconazole. The initial dosage of fluconazole will be 900 mg taken each day for 2 weeks. This will be followed by fluconazole 450 mg orally each day for 8 weeks. Finally, maintenance treatment with fluconazole 200mg orally each (2 tablets of 100 mg procured especially for the study) day will continue until CD4 \>200 cells/µL for at least 6 months. CrAg negative Fluconazole Patients with CrAg negative results will be managed as other HIV positive patients according to the national guidelines
