Study summary

In Mexico City, the main cause of mortality among people living with HIV (PLHIV) continues to be opportunistic infections (OIs). Early detection of OIs allows their timely treatment and improves their prognosis. The use of rapid diagnostic tests (RDT) based on antigens of the most frequent causative agents of OIs allows adequate screening of these patients and facilitates decision making at the point of care. Unfortunately, these studies are not widely available in the different PLHIV care centers in the CDMX. We will conduct an open-label, non-inferiority uncontrolled clinical trial to investigate the diagnostic performance of urinary lipoarabinomannan, urinary Histoplasma antigen and serum Cryptococcus antigen in patients presenting for care with advanced HIV in CDMX, supported by rapid cluster of differentiation 4 (CD4) testing with lateral flow technology. Four referral hospitals will participate over 12 months. All patients with diagnosed HIV disease and suspected advanced disease presenting for care at participating centers will be included in the study. An inventory of approximately 1000 RDT will be obtained and distributed among the participating sites. A study coordinator will be hired and will visit each site once a week to collect the study variables and follow up on the included patients. The primary outcome of the study will be the percentage of patients with advanced disease who present with diagnoses made by RDT compared to historical controls of patients diagnosed with OI in 2022 at participating centers by conventional methods. Secondary outcomes will be time to initiation of antiretroviral therapy (ART), time to initiation of OI treatment, and 30-day mortality after HIV diagnosis.

Inclusion criteria

  • Positive ELISA test or positive viral load for .
  • Patients with suspected or confirmed advanced HIV disease defined as follows:

    • Confirmed: asymptomatic patients with less than 200 cells/ml within 3 months of study inclusion or confirmed diagnosis of an AIDS-defining opportunistic illness within the last 3 months.
    • Suspected: patients who, irrespective of CD4 count, present any symptoms suggestive of systemic infection that, at the discretion of the treating physicians, produce suspicion of an AIDS-defining opportunistic disease (e.g., fever, productive cough, diaphragmatic diapers, etc.). Fever, productive cough, nocturnal diaphoresis, altered mental status, headache, lymphadenopathy, dermatological lesions) or that meet criteria for HIV wasting syndrome (loss of 10% of baseline weight plus the presence of chronic diarrhea or chronic weakness and an episode of fever in the last 30 days).
  • Patients without effective antiretroviral therapy defined as not having received antiretroviral treatment in the last 3 months or in virologic failure (2 consecutive viral loads with more than 1000 copies/ml).

Exclusion criteria

Exclusion Criteria:

  • Patients with a viral load of less than 1000 copies/ml.
  • Patients presenting for care having started treatment for systemic mycoses (amphotericin B or azoles) and tuberculosis.
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.
