NCT ID: NCT05220163 Recruiting - HIV Infections Clinical Trials

Evaluating the Impact of Computer-assisted X-ray Diagnosis and Other Triage Tools to Optimise Xpert Orientated Community-based Active Case Finding for TB and COVID-19

Start date: February 23, 2022
Phase: N/A
Study type: Interventional

Tuberculosis (TB) is now the commonest cause of death in many African countries. Globally, ~35% (almost 1 in 3) of TB cases are 'missed' (remain undiagnosed or undetected). In sub-Saharan Africa, 40-50% of the TB case burden remains undiagnosed within the community. These 'missed' TB cases (at primary care level) serve as a reservoir, which severely undermines TB control. With rapid advances in the development of TB screening tests, the investigators aim to determine the pragmatic utility of computer-assisted x-ray diagnosis (CAD). Recent data suggest that CAD performs on par with experienced radiologists to identify potential TB cases, hereby reducing the frequency at which Xpert tests are requested and helps to focus limited resources on the relevant cases. In addition, the investigators aim to test nascent screening technologies for TB diagnosis such as evaluating urine-based TB screening biosignatures. The COVID-19 pandemic has ravaged African peri-urban communities where TB is also common. With the pressing need to improve screening and diagnosis of COVID-19, the investigators plan to explore the potential for urine- and blood-based COVID-19 screening assays. Symptoms of COVID-19 and TB overlap, and limited affordability, as well as the stigma associated with both diseases, severely limits testing. Data are now urgently needed about the feasibility of co-screening and testing for TB and COVID-19. The utility of such an approach, if any, has not been studied in African communities.

Up to approximately 250 participants will be in the study for approximately seven years. No intervention is provided in the study.

NCT ID: NCT05127070 Recruiting - Prematurity Clinical Trials

Evaluating the NeoTree in Malawi and Zimbabwe

Start date: October 1, 2019
Phase:
Study type: Observational

Neonatal mortality remains unacceptably high. Globally, the majority of mothers now deliver in health facilities in low resource settings where quality of newborn care is poor. Health systems strengthening through digitial quality improvement systems, such as the Neotree, are a potential solution. The overarching aim of this study is to complete the co-development of NeoTree-gamma with key functionalities configured, operationalised, tested and ready for large scale roll out across low resource settings. Specific study objectives are as follows: 1. To further develop and test the NeoTree at tertiary facilities in Malawi and Zimbabwe 2. To investigate HCPs and parent/carer view of the NeoTree, including how acceptable and usable HCWs find the app, and potential barriers and enablers to implementing/using it in practice. 3. To collect outcome data for newborns from representative sites where NeoTree is not implemented. 4. To test the clinical validity of key NeoTree diagnostic algorithms, e.g. neonatal sepsis and hypoxic ischaemic encephalopathy (HIE) against gold standard or best available standard diagnoses. 5. To add dashboards and data linkage to the functionality of the NeoTree 6. To develop and test proof of concept for communicating daily electronic medical records (EMR) using NeoTree 7. To initiate a multi-country network of newborn health care workers, policy makers and academics. 8. To estimate cost of implementing NeoTree at all sites and potential costs at scale

NCT ID: NCT05007821 Recruiting - Tuberculosis Clinical Trials

Linezolid Dosing Strategies in Drug-Resistant TB

Start date: August 11, 2022
Phase: Phase 2
Study type: Interventional

The purpose of the study is to evaluate the efficacy (how well the medicines work) and tolerability (whether participants stop treatment because of side effects from a drug or treatment) of an anti-TB treatment regimen that compares two doses of linezolid (LZD), combined with bedaquiline (BDQ), delamanid (DLM), and clofazimine (CFZ). This study will also measure the level of these medicines in the participants' blood.

NCT ID: NCT04860323 Recruiting - HIV Infection Clinical Trials

Analytical Treatment Interruption (ATI) to Assess the Immune System's Ability to Control HIV in Participants Who Became HIV-infected During the HVTN 703/HPTN 081 AMP Study

Start date: May 28, 2021
Phase: N/A
Study type: Interventional

The purpose of this study is to learn whether having the AMP Study antibody (called VRC01) in a person's body might help their immune system control HIV better, even without HIV medication called antiretroviral therapy or ART, if they get HIV. This study will evaluate the viral and immune system responses in an Analytical Treatment Interruption (ATI), in participants who received VRC01 or placebo and got HIV while enrolled in HVTN 703/HPTN 081 (NCT02568215). Participants in this study will stop taking their HIV medication. They will stay off HIV medication unless and until the HIV levels in their blood show that their immune system is unable to control the HIV or they meet other ART re-start criteria as noted in section "Detailed Description". While they are not taking HIV medication, their HIV levels will be tested frequently, and their health will be monitored closely. This is called an analytical treatment interruption, or an ATI. An ATI is an experimental procedure that is only used in carefully monitored research.

NCT ID: NCT04782739 Recruiting - HIV Infections Clinical Trials

Evaluation of the Impact of the COVID-19 Pandemic on Provision and Uptake of Services for the Prevention of Mother-to-child Transmission of HIV and Syphilis in Zimbabwe

Start date: March 15, 2021
Phase:
Study type: Observational

The COVID-19 pandemic and response are likely to lead to severe unintended consequences for the prevention of mother-to-child transmission (PMTCT) of HIV and syphilis. Zimbabwe has made huge progress in coverage of antenatal testing of HIV and syphilis, which reached 98% and 91% in 2019, and is aiming for dual elimination. However, there is emerging evidence of disruption to health services due to COVID-19, similar to that seen in prior epidemics, which may reverse this progress. Mathematical modelling has estimated 3 and 6 month interruptions to ART supply would lead to 1.67 and 2.07 times more babies being born with HIV in SSA over the next year respectively. This study aims to provide real-world data to understand the effects of COVID-19 on the provision and uptake of PMTCT services. Our study has five objectives. Firstly, to conduct a retrospective analysis of national data routinely collected by healthcare facilities to explore changes before, during and after the pandemic in key indicators related to antenatal testing and treatment of HIV and syphilis, and management of HIV-exposed and infected infants. Secondly, data on neonates admitted to Sally Mugabe Central Hospital, already collected for the NeoTree study, will be analysed to explore the impact of COVID-19 on the number of HIV-exposed infants hospitalised, their clinical status at presentation and outcomes. Thirdly, qualitative studies with mothers and healthcare workers will explore barriers to optimal engagement with care and provision of PMTCT services respectively. Fourthly, quantitative results on testing and ART provision will be used to model the impact of disruptions on the rate of PMTCT of HIV enabling policy makers to plan for subsequent waves of COVID-19 and future epidemics. Finally, educational materials will be developed, piloted and disseminated during the project to provide information to pregnant women on safe access to PMTCT services.
