Addiction, HIV and Tuberculosis in Malaysian Criminal Justice Settings

Opioid DependenceAddiction3 more

The purpose of this study is to conduct empiric studies of tuberculosis (TB) among people in prison with and without a history of opioid dependence. This includes: a) comprehensive TB diagnostic study (symptom screening, chest x-ray, tuberculin skin test, acid-fast bacilli smear, Gene Xpert, and sputum culture) to determine best practices for screening HIV+ and HIV- prisoners; b) A RCT of latent TB infection prevention strategies among HIV+ and HIV- prisoners with high prevalence of hepatitis C (HCV) using standard 40-week daily isoniazid (40H) vs short-course weekly isoniazid + rifapentine (12HR); and c) a 2-arm preference trial comparing post-release TB treatment completion in patients on opioid agonist treatment (methadone) vs no opioid agonist treatment in patients being treated for active or latent TB, or patients with no TB, who are transitioning to the community. Investigators will also use this data, and publicly available data to complete agent-based modeling for comparative and cost-effectiveness of various TB screening and treatment strategies among prisoners, and upon community transition post-release from prison.

Sequencing Mycobacteria and Algorithm-determined Resistant Tuberculosis Treatment Trial

Rifampicin Resistant TuberculosisDrug-resistant Tuberculosis2 more

The primary aim of this pragmatic trial is to determine the effectiveness of a Whole Genome Sequencing (WGS) Drug Sensitivity Testing (DST) strategy to guide individualised treatment of rifampicin resistant tuberculosis (RR-TB) patients. The primary objective is to determine the effectiveness of this WGS DST strategy in patients diagnosed with RR-TB. We will additionally perform an exploratory health economics evaluation of both arms, and will determine the feasibility of the WGS DST strategy.

Community Health Worker Training to Reduce Depression and Substance Use Stigma in TB/HIV Care in...

Substance-Related DisordersMental Disorder10 more

Poor engagement in care contributes to HIV- and TB-related morbidity and mortality in South Africa (SA). Community health workers (CHWs) are frontline lay health workers who work to re-engage patients who are lost to follow-up (LTFU) in HIV/TB care. Patients with depression and substance use (SU) have a greater likelihood of being LTFU in HIV/TB care, and there is evidence that CHWs may exhibit stigma towards these patients. When CHWs have negative attitudes towards these patients, on average they spend less time with these patients, are less likely to implement evidence-based practices, and deliver less patient-centered care. Therefore, this purpose of this study is to examine the implementation and preliminary effectiveness of a brief training ("Siyakhana"). The purpose of this training is to provide CHWs with psychoeducation, skills, and support around working with HIV/TB patients with depression/SU. The investigators will assess the training's implementation and changes in CHWs' stigma towards HIV/TB patients with depression/SU.

TuberculosisHIV

Single-arm, multi-center, Phase I/II clinical trial, in two groups. Individuals with HIV infection taking Efavirenz (EFV), nevirapine (NVP) or lopinavir/ritonavir (LPV/r) and two nucleoside reverse transcriptase inhibitors (NRTI) who have undetectable HIV viral load (VL) (< 50 copies/mL) and an indication for tuberculosis (TB) preventive treatment (TPT), will be switched to dolutegravir (DTG) with tenofovir/emtricitabine (TDF/FTC), tenofovir/lamivudine (TDF/3TC), abacavir/lamivudine (ABC/3TC) or zidovudine/lamivudine (AZT/3TC) in accordance with South African National HIV Guidelines. Groups 1 and 2 will receive weekly HP for 12 total doses starting 4 weeks after initiating DTG. Individuals who are on an existing DTG-based plus two NRTI antiretroviral therapy (ART) regimen for at least four weeks (and have not received efavirenz, or nevirapine or lopinavir/ritonavir for at least four weeks) who have an undetectable HIV viral load may also participate.

Bring BPaL2Me Trial Comparing Nurse-Led RR-TB Treatment to Physician-Led RR-TB Treatment

Drug Resistant Tuberculosis

The goal of the BringBPaL2Me Trial, a multi-principal investigator, multi-site, cluster randomized, non-inferiority trial is to compare nurse-led RR-TB treatment in primary care clinics to standard of care physician-led RR-TB treatment at district hospitals in the provinces of KwaZulu-Natal, Gauteng, and Eastern Cape. The main aim is to conduct a 5-year, analyst and clinical safety review committee blinded, multi-site, cluster randomized trial to evaluate 1) treatment outcome; 2) safety; 3) patient associated catastrophic costs with the following hypotheses: Outpatient nurse-led treatment in PCCs will be non-inferior to outpatient physician-led treatment at hospital-based outpatient sites among RR-TB patients, regardless of HIV co-infection, as determined by a successful treatment outcome [H1]. The proportion of SAEs identified will not significantly differ by blinded, independent review [H2]. Patient associated catastrophic costs (i.e., costs 20% or more of household income) will be lower in nurse-led treatment [H3].

Using BCG Vaccine to Understand Tuberculosis Infection

Tuberculosis

Tuberculosis (TB) is a disease that usually causes an infection in the lungs. The only vaccine to prevent TB is called BCG (Bacillus Calmette-Guérin). BCG contains a live germ similar to Mycobacterium tuberculosis, the germ that causes TB. BCG does not work very well, and TB remains the most common cause of death by infection worldwide. Human challenge models involve exposing healthy volunteers to an infectious disease in a safe and controlled way. This helps researchers understand more about an infectious disease and the body's response and can help develop new vaccines and treatments. The purpose of this study is to set up a human challenge model using BCG to understand how the body responds to this. If our human challenge model works well it may be used to help researchers develop new vaccines and tablets to treat TB in the future. This study will recruit healthy volunteers, of all genders, age 18-50 years. The first part of the study (phase A) will recruit 10 participants. Participants in phase A will receive intradermal injection with BCG into the upper arm at three times the usual dose. On day 14 after BCG the following skin samples will be taken from the BCG site with the use of local anaesthetic: skin swab, microbiopsy, skin scrape and punch biopsy. Participants in this phase of the study will also have blood tests to ensure they are safe to take part and to monitor the immune response to BCG. The overall aim of this part of the study will be to ensure BCG can be isolated (grown in culture and by molecular techniques) from participants' BCG site 14 days after the injection. The investigators aim to test whether BCG can be isolated by punch biopsy and minimally invasive techniques (microbiopsy, skin scrape and skin swab). If the investigators find that they can isolate BCG successfully using the minimally invasive methods of skin sampling and the participants have not experienced any serious adverse events, they can proceed to phase B of the study. In phase B 20 participants will be recruited. These participants will receive BCG as described for phase A. They will then have serial skin samples taken using either microbiopsy, skin scrape or skin swab on days 0, 2, 7, 14 and 28. The focus of this phase of the study is to assess immune responses to intradermal injection at the local (skin), systemic (blood) and respiratory mucosal (nose) compartments. This will involve longitudinal sampling from blood, nose and skin to measure BCG growth and the immune response over time.
