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.
This study will pilot test a brief, scalable intervention called Maisha (Swahili for life), to address HIV stigma for women presenting to antenatal care in Tanzania and male partners who accompany them. The intervention will include: 1) a video and brief counseling that addresses HIV stigma at the start of the ANC visit (prior to HIV testing), and 2) two stigma-based counseling sessions for individuals who are HIV infected, building on the video content to provide emotional support, promote acceptance, address stigma, and reinforce care engagement. The primary intervention outcome is engagement in PMTCT care among women who are HIV infected. The investigators will also examine HIV stigma outcomes (enacted, anticipated, internalized) among all groups of participants, including individuals who are already established on ART and indiviudals who are HIV uninfected.
Vulnerability to HIV infection in Adolescent Girls and Young Women (AGYW) is mainly influenced by structural factors which mediate through sexual risk behavior. The Sauti program as implementing partner of the DREAMS initiative will provide unconditional cash transfer on quarterly basis to vulnerable AGYW in selected districts of Tanzania. The CARE study will evaluate the impact of this activity through a cluster randomised controlled trial that involves quantitative and qualitative research techniques. The study will inform policy makers on the impact of Cash transfer programs in AGYW as a tool to reduce vulnerability to HIV infection in Adolescent Girls and Young women.
This pilot phase I trial studies how well treatment with vincristine and bleomycin affect quality of life in patients with acquired immunodeficiency syndrome (AIDS)-associated Kaposi sarcoma.
Sub-Saharan Africa, with more than 56 million orphans worldwide, is the most affected region in terms of orphans to be cared for (UNICEF, 2014). The recently developed preventative approach Interaction Competencies with Children - for Caregivers (ICC-C; Hecker, Mkinga, Ssenyonga, & Hermenau, 2017) trains the essential interaction skills in working with children. The focus here is on strengthening a warm, sensitive and reliable relationship between caregiver and child as well as on non-violent education strategies. In a first pilot study the feasibility of the approach icould be demonstrated (Hermenau, Kaltenbach, Mkinga, & Hecker, 2015). The study applies a two-arm cluster-randomized controlled design. The participating institutions will be randomly divided into intervention and control bodies. The follow-up examination should take place three months after the intervention. All caregivers in facility (N = approx. 150) and 25 randomly selected children (age: 6-12) per facility (N = 200) will be included in this study.
The investigators will conduct a cluster randomized trial to determine the effectiveness of an educational intervention for religious leaders in promoting uptake of family planning in Tanzania.
The purpose of this study is to compare the efficacy and safety of 26 weeks of delamanid (DLM) versus 26 weeks of isoniazid (INH) for preventing confirmed or probable active tuberculosis (TB) during 96 weeks of follow-up among high-risk household contacts (HHCs) of adults with multidrug-resistant tuberculosis (MDR-TB) (index cases). High-risk HHCs are those with HIV or non-HIV immunosuppression, latent TB infection, and young children below the age of 5 years.
Local application of antibiotics directly to the traumatic wound is a promising strategy for the prevention of infection after open tibia fractures, which are a significant source of disease burden globally, particularly in low-income countries. This pilot study aims to assess feasibility of a randomized controlled trial to measure the effect of locally applied gentamicin on risk of infection for open tibial fractures in Tanzania. If proven effective, local gentamicin would be a highly cost-effective strategy to reduce complications and disability from open tibial fractures that could impact care in both high- and low-income countries.
The current therapy regimens in Sub-Saharan countries, consisting of standardized first and second line drug combinations, yield a high rate of treatment failure, even within the first 12 months of therapy (23). These and other facts hint at the need for HIV resistance testing to improve treatment outcomes in resource-limited settings, but no prospective clinical data about this intervention exists. The proposed study aims to evaluate the impact of HIV drug resistance testing, and subsequent change to an individualized (second-line) therapy based on the resistance profile, in Tanzanian patients (children, adolescents and adults) with virological failure of their first-line and second-line therapy. Additionally, prevalence, patterns and clinical impact of HIVDR will be assessed, as well as the effect of enhanced adherence counselling. The results of this study will help doctors to take evidence-based diagnostic and therapeutic decisions at an individual level, and will inform policy-makers in their decisions about future treatment and management concepts for HIV/AIDS.
The massive scale-up of Long Lasting Insecticidal Nets (LLIN) has led to a major reduction in malaria burden (up to 50%) in many sub-Saharan African countries. This progress is threatened by the wide scale selection of insecticide resistant malaria vectors. New types of LLIN combining a mixture of two insecticides or an insecticide and a synergist have been developed to control resistant mosquitoes. The efficacy of three bi-treated LLIN are compared to a standard LLIN in a four-arm, single blinded, cluster-randomized trial in Misungwi district, Tanzania. The arms are; 1/ Royal Guard, a net combining pyriproxyfen (PPF), which is known to disrupt female reproduction and fertility of eggs, and the pyrethroid alpha-cypermethrin, 2/Interceptor G2, LLIN incorporating a mixture of two adulticides with different modes of action; chlorfenapyr and a pyrethroid (alpha-cypermethrin), and 3/ Olyset Plus an LLIN which incorporates a synergist, piperonyl butoxide (PBO), to enhance the potency of pyrethroid insecticides, and 4/ The control arm: Interceptor treated a standard LLIN treated with alpha-cypermethrin. The primary outcome of the trial will be cross-sectional community prevalence of malaria infection (by RDT) in children aged 6 months to 14 years at 12 and 24 months post-intervention.
This study is a double-blind randomized clinical trial conducted with two settings in Africa and one in Asia, namely Côte d'Ivoire, Pemba (Zanzibar, Tanzania) and Lao PDR. This study aims at providing evidence on the efficacy and safety of co-administered albendazole and ivermectin versus albendazole monotherapy (standard of care) against whipworm (T. trichiura) infections in children and adults (6-60 years). The efficacy of the treatment and potential extended effects on follow-up prevalence will be determined 14-21 days, 6 months and 12 months post-treatment by collecting another two stool samples. The cure rate will be calculated as the percentage of egg-positive subjects at baseline who become egg-negative after treatment.
