There are about 472 clinical studies being (or have been) conducted in Tanzania. 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.
We will pilot an intervention to deliver sexual and reproductive health services, including HIV self-testing (HIVST) and contraception, to adolescent girls and young women (AGYW) at accredited drug dispensing outlets (ADDOs) in Shinyanga, Tanzania. In a 4-month randomized pilot study, we will compare mediating outcomes (AGYW patronage, product distribution, and referral) between 10 intervention and 10 comparison ADDOs, using data from time-location surveys of customers and inventory distribution and referral records.
Sexually transmitted infections (STI) are important causes of reproductive health morbidity and mortality, and have long been implicated as major co-factors in the sexual transmission of HIV. Both ulcerative and non-ulcerative STI have been found to be strongly associated with HIV in cross-sectional and prospective studies and hence STI prevention and care are important aspects of HIV prevention. Periodic Presumptive Treatment of STIS (PPT) where risk populations are presumptively treated with a single dose of Azithromycin+Cefixime in regular intervals of 3 months has been shown to be effective in reducing STI prevalence at population level and has recently been integrated into the National STI guidelines of Tanzania. The USAID funded Sauti program will be one of the first to implement these new guidelines and roll out PPT in high risk populations in selected regions in Tanzania. This study will evaluate the impact of PPT as delivered by the Sauti program on prevalence of STIs in men who have sex with men and female sex workers in Dar es Salaam and Shinyanga respectively.
This study we will evaluate the benefit of HIV testing in neonates born from HIV-infected mothers in Tanzania and Mozambique. The study will use and evaluate novel point-of-care diagnostic systems, that can provide neonatal HIV test results within 2 hours. We will evaluate if HIV testing at birth followed by immediate neonatal HIV treatment initiation will lead to lesser infant's sickness, HIV progression or even death as compared to the current standard procedure which is infant HIV testing at week 6 after delivery. This will be associated with a cost-effectiveness analysis in order to guide national HIV programs for their guidelines. The study will further evaluate if point-of care viral load testing in mothers at birth will identify high-risk scenarios for HIV transmission from the mother to her child. This should lead to enhanced prophylactic treatments in HIV-exposed infants and we hypothesize that PoC VL monitoring at birth leads to lower transmission rates. The study will be performed at 28 maternity health facilities in Tanzania and Mozambique, half of them will be randomized to provide birth HIV PoC infant and maternal viral load testing, the other half will provide the current standard of care (infant HIV testing at week 6, no PoC VL monitoring at birth for the mother). The study is conducted in public health settings, and some study objectives also focus on how successful modern HIV treatments can be provided to infants, if HIV testing and treatment procedures are feasible for nurses and midwives, and if these procedures can be carried out in a timely manner. This study also includes a basic research component that will investigate how HIV spreads in the body of HIV-infected infants, and if early infant HIV diagnosis and treatment can reduce the spread in cells of HIV-infected individuals.
The goal of this study is to pilot test a culturally tailored Family Psychoeducation model (KUPAA) for adults with psychotic disorders and their relatives that is appropriate for cultural settings inclusive of both traditional and biomedical ideas about mental illness and that incorporates relatives as co-facilitators of the intervention.
Globally, 15% of all babies, amounting to 20 million infants each year, are born low birthweight (LBW), defined less than 2500 grams (5.5 lbs). Compared to normal weight infants, LBW infants are at higher risk of morbidity, mortality, and poor growth (Risnes et al 2011; Larroque et al 2001; WHO 2006). The main causes of LBW are preterm birth, intrauterine growth restriction (IUGR), or their combination. Unfortunately, there is a paucity of information around feeding practices and optimal feeding strategies for this population, particularly for LBW infants who struggle with breastfeeding or growth. This study hopes to address these gaps.
Trachomatous inflammation-follicular (TF) is diagnosed by looking for clinical signs of infection of everted eyelids (conjunctivae) of children. The overall objective of this project is to investigate the effectiveness, acceptability and feasibility of an app-based versus slide-based IGA for trachoma graders. Fieldwork will take place during routine Tropical Data trainings. A non-inferiority randomised controlled trial design will be employed, with grader trainees randomised to app- or slide-based training, and then to app- or slide-based IGA testing. The training and IGA testing method will be compared with field IGA test score to determine which method best predicts passing the field IGA test.
Trachomatous inflammation-follicular (TF) is diagnosed by looking for clinical signs of infection of everted eyelids (conjunctivae) of children. The overall objective of this project is to develop a smartphone application and assess its acceptability and feasibility. Fieldwork will take place during routine Tropical Data trainings and population-based prevalence surveys supported by Tropical Data. Healthy adult volunteers in London will have photos of their conjunctivae taken to develop the app initially, with iterative improvements to the app based on image quality achieved. For fieldwork, images of the conjunctivae of children will be have photos of their conjunctivae taken with a digital single lens reflex (DSLR) camera and the newly developed smartphone app. Grading of the photos will be compared with field grading, to compare grading agreement, to assess utility for supervision, quality assurance and training purposes.
The rational of this study is to provide evidence on the safety and efficacy of a new chewable tablet of mebendazole compared to the standard tablet in preschool- and school-aged children infected with hookworm.
Background: In the last 2 decades, Tanzania made great improvements in the renal replacement therapy infrastructure and services. However, renal replacement therapy remains a challenge in the developing world in terms of inadequate renal registries, and limited published literature. Objectives: This study will identify predictors of mortality, identify common causes of infection and hospitalization, their incidences, prevalence, and time-to-event analysis and analyze short and long-term survival of end-stage renal disease (ESRD) patients on hemodialysis in two hemodialysis centers in Dodoma, Tanzania. Furthermore, this study will establish a registry to be called Tanzania Registry for Chronic Renal Failure (TRCRF). Methodology: This will be a prospective-observational study (Patient registry). It will be conducted in Tanzania, a developing world country involving two hemodialysis centers, namely Benjamin Mkapa Hospital and UDOM Health center, both affiliated with the University of Dodoma. Data will be collected by accessing patients' records receiving hemodialysis due to ESRD in the two centers from September 2019 to September 2024. Patients' demographics, medical history, investigation findings, and hemodialysis adequacy will be extracted as independent outcomes. In contrast, the outcome (i.e., Death) during the follow-up will be extracted as a primary dependent outcome. Binary logistic regression will be applied to come up with statistically significant predictors of deaths. Other outcomes will be incidences, prevalence, and time-to-event analysis of common causes of infection and re-hospitalization. Kaplan-Meier survival curves will be constructed from statistically significant predictors of deaths, and patients' survival at 1, 3, and 5 years will be illustrated.
The core of this study is a cluster randomized controlled trial (RCT) of antenatal clinics which are located in four districts in Tanzania. We are conducting an effectiveness (pragmatic) rather than an efficacy (explanatory) trial because we are looking to measure the degree of benefit under 'real world' conditions. Although pragmatic and carried out in real world conditions, the proposed size and scope of the trial will allow us to achieve a robust evaluation of outcomes and determine the effectiveness of our intervention. A cluster design is the most appropriate type of methodology (rather than individual randomization by pregnant woman) as the intervention can be delivered to the entire health facility (of those facilities in the intervention group). The intervention is to implement an mHealth strategy to improve detection and management of PE (pre-eclampsia). This study is a multi-level, mixed-methods design that includes a cluster-randomized controlled trial (RCT) of antenatal clinics in rural Tanzania. Thirty health facilities have been randomized to control facilities and thirty facilities have been randomized to intervention clinics. All randomized clinics have upgraded antenatal care (ANC) and skilled birth attendants present. Nurses in the intervention clinics in this cluster arm will receive mHealth-based education in detection and management of PE and will be instructed and encouraged to follow a guideline-driven approach supported by mHealth (educational modules that provide decision support and reminders through the facility smartphone/tablet). At all antenatal visits, pregnant women will have their blood pressures measured and urine assessed for proteinuria, and, the result will be automatically sent by SMS (short message service) with a unique patient identifier to a central site for monitoring and tracking. Community Health Workers (CHWs) linked to the facility site and local communities will be instructed on which women to have follow-up visits within their communities. For all those women found to be at risk for PE (as well as other high risk maternal conditions), an SMS will be sent to the CHW, and, the nurses at the ANC recommending timely follow-up and protocol steps for management at that facility or for transfer for further monitoring and management at a higher-level facility. The nurses participating in the study have been drawn from the health facilities themselves, in both control and intervention arms. Quantitative data will be collected on an ongoing basis through the mobile platform. Women are eligible for recruitment between 15 weeks and 36 weeks gestation.
