NCT05690607
During the Covid-19 pandemic era, patients indicated that they find a model of care incorporating remote consultations to be acceptable \[1-3\]. Remote accessibility to care can be enhanced by using new technology to allow small volume testing for routine blood samples. This study aims to prospectively validate the use of small volume blood sampling for routine HIV-1 and Hepatitis B Virus (HBV) viral load (VL), liver function tests (LFTs) and creatinine, and assess the acceptability of this method of blood sampling to people living with HIV (PLWH). These tests form the usual minimum required for safe monitoring on a routine basis to determine viral activity, liver and renal function in patients either on or off antiviral therapy. The UK based Doctors Laboratory TINIES small volume blood testing kits comprise microcontainers manufactured by BD Diagnostics designed for sample collection from skin puncture, along with home testing pack with lancets, instructions and Royal Mail postal packs. We will collect TINIES samples alongside routine venepuncture samples in people attending their routine clinic follow ups. We will then send kits to different participants to collect samples in their own home, along with a follow up questionnaire (written/online). Finally, we will conduct a more in-depth telephone interview for a subset of patients to qualitatively assess acceptability. Routine use of this method of testing could revolutionise care of people living with chronic blood borne viruses, for example HIV and chronic HBV. TINIES could enable remote monitoring, increasing ease of access to care, reducing clinic appointment burden in otherwise healthy individuals, and reduce labour costs in the NHS, for example, by reducing phlebotomy appointments.
NCT05685641
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.
