Study summary

This will be a stepped wedge randomized trial design to evaluate the implementation of cryptococcal antigen (CRAG) screening and preemptive anti-fungal therapy of HIV-infected persons entering antiretroviral therapy (ART) outpatient treatment in Uganda. Those who are ART eligible with a CD4≤100 cells/mcL will have a serum/plasma CRAG performed by lateral flow assay. Those who are CRAG-positive and asymptomatic will be treated with high dose fluconazole. After 6 months survival with retention-in-care will be compared between those who are CRAG+ and CRAG negative

  • Cryptococcal antigen (CRAG) positive
  • age >14 years

Exclusion criteria

Exclusion Criteria:

  • Suspected Cryptococcal meningitis
  • Prior known history of cryptococcal meningitis
  • currently receiving antiretroviral therapy
  • Allergy to any azole antifungal medication
  • Persons with known serious hepatic co-morbidities, transaminitis, or clinical jaundice who should not receive fluconazole in the opinion of the study investigator.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

CD4 count

The number of CD4 cells, a type of white blood cell, in a given amount of blood. It is used to follow how well the immune system is doing in HIV.

What researchers measure

Primary outcomes

  1. Retention in care

    1. before/after CRAG screening implementation (All persons) 2. CRAG positive persons treated with high-dose fluconazole as compared to 6-month survival of CRAG negative persons who are eligible for antiretroviral therapy.

    Time frame: 6-month

Secondary outcomes

  1. Cryptococcal meningitis-free survival time

    Cryptococcal meningitis-free survival time in those who are asymptomatic CRAG positive and treated with fluconazole compared to CRAG-negative persons with CD4\<100 cells/mcL

    Time frame: 6-month

  2. Survival Time

    Survival time among CRAG+ vs. CRAG negative persons with CD4\<100 cells/mcL.

    Time frame: 6-month

  3. Uptake of CRAG screening and preemptive treatment

    Time frame: baseline

  4. Time from CRAG+ test to receipt of fluconazole therapy

    Time frame: Days from CD4 testing

  5. All-cause discontinuation of fluconazole

    Number of participants with early discontinuation of fluconazole for any reason (e.g. non-compliance, adverse event)

    Time frame: 6-month

  6. Percentage of participants with symptomatic cryptococcal meningitis

    Time frame: baseline

  7. Risk factors for symptomatic cryptococcal meningitis

    Time frame: baseline
