There are about 292 clinical studies being (or have been) conducted in Zambia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
To achieve global goals for the treatment of HIV, many countries are piloting and scaling up differentiated service delivery models (DSD). A handful of efforts have been formally described and evaluated in the literature; many others are being implemented formally or informally under routine care, without a research or evaluation goal. For most countries however, the investigators have little evidence on progress and challenges at the facility level-the number of patients actually participating in DSD models, health outcomes and non-health outcomes, effects on service delivery capacity and clinic efficiency and operations, and costs to providers and patients. Alternative Models of ART Delivery: Optimizing Benefits (AMBIT) is a set of data synthesis, data collection, and data analysis activities aimed at generating information for near- and long-term decision making and creating an approach and platform for ongoing evaluation of differentiated models of HIV treatment delivery. The first AMBIT protocol, "Gathering Records to Evaluate Antiretroviral Treatment" (GREAT, Zambia Ref. No. 2019-Sep-030), collects and analyzes comprehensive patient medical record data, allowing us to assess the effect of DSD models on patients' clinical outcomes and to evaluate uptake of DSD models at scale. The Sentinel-Zambia study, the second AMBIT protocol, is examining the effect of DSD models on patient and provider satisfaction, service delivery capacity and quality, costs to patients, and other outcomes for which data are not routinely collected in patient-level medical records. The first round of Sentinel-SA was conducted in 2021. The AMBIT 2.0 protocol will allow up to four additional annual rounds of data collection, in 2022-2025. The investigators collected clinic aggregate data, conducted surveys of patients and providers, and observed operations at a selected set of 12 Zambian healthcare facilities and their affiliated DSD models in Round 1. Round 2 (2022) and later rounds will collect the same types of data at 12 facilities in Zambia and will expand the study's research questions to include differentiated models of HIV testing and linkage to care. Results are expected to inform Zambian policy makers and other local and international stakeholders on the actual implications of DSD models for patients, health system operations, and healthcare budgets.
The objective of this mixed-methods study is to evaluate the effectiveness of a school-based safe-space program delivered to secondary school students in Zambia. The quantitative component of the study uses a randomized controlled trial to measure changes in students' experience of school-related gender-based violence (SRGBV), attitudes towards gender and SRGBV, socio-emotional well-being, and school climate, among other outcomes. Meanwhile, the qualitative component of the study aims to understand the prevailing norms around SRGBV in schools, the perception of the intervention and its impact, and the potential mechanisms through which the intervention generates its outcomes.
Open-label randomized controlled trial to test the effectiveness of whole blood transfusion for improving survival in children with severe malaria complicated by thrombocytopenia.
A prospective, exposure-control cohort study of older adults living with HIV comparing the neurological status of those who have had HIV infection for a longer period of time (long HIV group) to age, gender, and community-matched comparison group who have had HIV infection for a shorter period of time (short HIV group).
Continuous vital sign monitoring is a basic tenet of specialized care in the developed world that is vastly underutilized during hospital or clinic admissions or outpatient routine visits in most low-and-middle income countries (LMICs). Despite the positive outcomes associated with vital sign monitoring (i.e., increased survival-to-discharge rates, lower complication rates and shorter length of stay in hospital), the prohibitive costs of conventional patient monitors and the difficulty in maintaining complex medical equipment limit its practice in the developing world. Currently, due to lack of medical supplies, most ANC clinics - within the health facilities or during outreach activities - do not monitor for vital signs and blood pressure among pregnant women. While many devices exist, their ease of use and high-cost, including maintenance costs, hinder screening and monitoring programs in low resource settings. Accurate and low-cost vital sign monitoring devices are required to improve identification and treatment of women with danger signs during their routine ANC visits. To meet the growing demand for vital sign monitors during the COVID-19 pandemic, Neopenda has adapted an affordable, wearable, wireless vital sign monitoring solution (neoSpotTM), that measures temperature, respiration rate, blood oxygen saturation, pulse rate, and blood pressure.
The goal of this observational study is to longitudinally investigating subjects with inaugural acute optic neuritis (ON). The main questions it aims to answer are: - Does the time to corticosteroid treatment affect the visual outcome at 6 months in subjects with acute multiple sclerosis (MS)-, aquaporin 4-IgG positive (AQP4-IgG+) and myelin-oligodendrocyte-glycoprotein-IgG positive (MOG-IgG+) ON? - How differ clinical, structural, and laboratory biomarkers in subjects with acute ON, including clinical isolated syndrome (CIS), MS-ON, AQP4-IgG+ON, MOG-IgG+ON and seronegative non-MS-ON? Participants will undergo - clinical examination, including clinical history, neurovisual and neurological tests - serum and cerebrospinal fluid examination - optical coherence tomography (OCT) - magnetic resonance imaging (MRI) - assessment of depression, pain, quality of life through validated questionnaires Researchers will compare subjects with MS-ON, AQP4-IgG+ON, MOG-IgG+ON and other ON (CIS, seronegative non-MS-ON) to detect diagnostic and predictive markers for the disease course.
Randomized phase II clinical trial which aims to assess the impact on 3-month mortality and safety of adding adalimumab to standard treatment (anti-tuberculosis drugs and corticosteroids) in HIV patients with tuberculosis meningitis in 3 countries (Brazil, Mozambique, and Zambia).
PRIORITY is designed as a 2-arm, randomized-controlled trial focused on postpartum women. The trial will recruit women who are diagnosed with moderate anemia based on a blood sample taken 6-48 hours after childbirth. A total of 4,800 eligible women, or 600 women per research site, will be consented and enrolled in the trial. The study hypothesizes that at 6 weeks post-delivery, prevalence of the non-anemic state in women in that received a single-dose IV iron infusion between 6 and 48 hours after delivery and prior to discharge from the facility will be greater than that of women given a supply of oral iron tablets taken twice daily for 6 weeks.
A double blinded, placebo-controlled, multicenter trial to evaluate effectiveness of azithromycin prophylaxis on mortality in advanced HIV.
This proposal tests the efficacy of a phone-based tobacco cessation intervention for people living with HIV (PLWH) in comparison to the standard of care (brief advice to quit) and nicotine replacement therapy (nicotine patches) in Uganda and Zambia. This study will provide insight into the efficacy, feasibility, applicability, and affordability of delivering tobacco cessation interventions through health care professionals at HIV treatment centers in two countries with different tobacco use patterns, policy environments, and health care resources. The previously tested SMS-platform to be used in this study is uniquely positioned to be scaled in low- and middle-income countries worldwide, in which case rigorous research showing even modest success in reducing the prevalence of tobacco consumption among PLWH could confer substantial health and economic benefits.
