There are about 38 clinical studies being (or have been) conducted in Haiti. 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 is a randomized, unblinded study comparing standard vs. same-day treatment for patients with TB symptoms (cough, fever, night sweats, or weight loss) at HIV diagnosis. Six hundred patients will be randomized in a 1:1 ratio to the standard group or the same-day treatment group. All study activities will take place at the GHESKIO Centers in Port-au-Prince, Haiti. The study population includes HIV-infected men and women ≥18 years of age who are ART-naïve, and who present with symptoms of TB (cough, fever, nights sweats, or weight loss >10%) at HIV diagnosis.
Despite overall declines in HIV incidence and mortality since ART scale-up in low and middle income countries, both have risen among youth. In addition, HIV-infected youth achieve inferior treatment outcomes compared to their adult counterparts in both high- and low-income countries, and these poorer outcomes are generally attributed to suboptimal adherence. Thus, there is a critical need for the development of adherence and risk reduction interventions for the growing cohort of these youth, and the proposed cognitive behavioral N'ap Grandi is one such intervention.
Depression is often the most prevalent mental health problem among people living with HIV (PLWH) worldwide, and if not adequately treated, it may impair response to antiretroviral treatment (ART) and the ability of individuals to adhere to medications and healthy behavior. Most patients with depression receiving ART in the poorest countries of the world are left untreated because no systematic approach or expertise is available. This study adapts an evidence-based model of depression care (Measurement-Based Care - MBC) using auxiliary HIV clinic staff, and tests feasibility and assesses costs among HIV positive patients beginning ART in Port-au-Prince, Haiti.
The DOLF Triple Drug Therapy for Lymphatic Filariasis study will determine the frequency, type and severity of adverse events following triple-drug therapy (IVM+DEC+ALB, IDA) compared to the standard two-drug treatment (DEC+ALB, DA) in infected and uninfected individuals in a community in 5 different countries. The objective is to acquire safety, efficacy, and acceptability data to assess the safety and acceptability of the IDA drug combination.
The investigators aim to evaluated a public health program in Haiti that introduced an oral cholera vaccine as part of comprehensive control efforts for a major cholera epidemic. Although the vaccine (Shanchol(R)) had been demonstrated to be very safe, and effective at preventing cholera in many settings, it had not extensively been used to control an outbreak, and it had not been extensively studied in populations that were previously naive to cholera (i.e. countries that had never had cholera before). This cholera epidemic was the first ever report of cholera in Haiti. After the cholera vaccination campaign was complete, the investigators aimed to evaluate the field efficacy of the vaccination campaign by evaluating the number of cases of cholera, and determining if cholera patients had been vaccinated. The investigators compared the rate of vaccination in cholera cases to controls from the community that had not had cholera in a case-control study. The investigators also performed a second study - a bias-indicator study - that enrolled patients with non-cholera diarrhea, and community controls. The role of the bias-indicator study was to evaluate for potential sources of bias, since the investigators could expect that cholera vaccination should have no effect on non-cholera diarrhea.
This research is being done to determine if Nitazoxanide (NTZ) will cause a significant decrease in the number of M. tuberculosis bacteria in sputum after 14 days of treatment. The study is being conducted at the GHESKIO Centers in Port au Prince Haiti
Screening of haitian children between the ages of 3 and 6 years old for amblyogenic risk factors with the use of the Spot photoscreener. The photoscreener results will be compared to the complete ophthalmologic evaluation. Primarily, this will allow evaluation of the performance of the spot photoscreener in the haitian children population. Secondarily, this study will gather epidemiological information on vision problems in the haitian children population.
The purpose of this study is to evaluate the pharmacokinetics, tolerability, and safety of once-weekly doses of rifapentine (RPT) and isoniazid (INH) in HIV-1-infected and HIV-1-uninfected pregnant and postpartum women with latent tuberculosis (TB).
This is a multicenter, randomized, placebo-controlled, double-blind study to evaluate the safety and immunogenicity of a 2 injection vaccine Chikungunya virus (CHIKV) and virus like particle vaccine (CHIKV VLP) in healthy adults.
The purpose of this study is to determine whether one or two four-month regimens of tuberculosis treatment are as effective as a standard six-month regimen for treatment of pulmonary tuberculosis (TB). All three regimens are administered daily, seven days each week, with direct observation of each dose by a health-care worker at least five of the seven days of each week. The standard six-month regimen is two months of isoniazid, rifampin, ethambutol, and pyrazinamide followed by four months of isoniazid and rifampin. The first short regimen is a single substitution of rifapentine for rifampin: two months of isoniazid, rifapentine, ethambutol, and pyrazinamide, followed by two months of isoniazid and rifapentine. The second short regimen is a double substitution of rifapentine for rifampin and moxifloxacin for ethambutol: two months of isoniazid, rifapentine, moxifloxacin, and pyrazinamide, followed by two months of isoniazid, rifapentine, and moxifloxacin. Target enrollment is 2500 participants. Each study participant will remain in the study for 18 months in order to include at least 12 months of evaluation of whether the participant's TB recurs.
