Study 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.

Read the 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.

Study population

Newly registering and ART-naive patients with advanced HIV infection

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Aged ≥ 18 years
  • Confirmed infection using National Testing Algorithm
  • ≤100 cells/μL
  • Able to provide written

Exclusion criteria

Exclusion Criteria:

  • History of prior CM
  • Receipt of systemic antifungal medication for more than 4 consecutive weeks within the past 6 months
  • Currently taking ART or history of ART for more than 4 weeks within the past year
  • Known to be currently pregnant or planning to become pregnant during the study period
Terms in these criteria, in plain language(3)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • CrAg(+) and CM(+)

    Patients with symptoms of CNS disease will be treated according to Vietnam national guidelines for HIV/AIDS management.

    Drug: Fluconazole

  • CrAg(+) and CM(-)

    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.

    Drug: Fluconazole

  • CrAg negative

    Patients with CrAg negative results will be managed as other HIV positive patients according to the national guidelines

    Drug: Fluconazole

Interventions

  • 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). Those who are CrAg-positive, but have no features of central nervous system (CNS) disease, will be treated with high-dose fluconazole.
