There are about 65 clinical studies being (or have been) conducted in Bolivia. 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.
Levels of blood pressure in adolescents with preeclampsia and eclampsia: Multicenter case-control study (Latin America). Maternities in Latin America: Two hospitals in Panama, one hospital in Mexico, one hospital in El Salvador, one hospital in Guatemala, two hospitals in Honduras, one hospital in Colombia, two hospitals in Peru and two hospitals in Bolivia. The objective is to evaluate the basal levels of blood pressure during pregnancy and determine if there is any increase that is associated with the development of preeclampsia and eclampsia without reaching the known values of 140/90 mm Hg. The sample is 1050: (350 Cases and 700 Controls).
Chagas disease is one of the most neglected vector-borne infectious disease worldwide. The first decades following the discovery of the pathology drove an international research enthusiasm, mainly concentrated on understanding the typical cardiac and digestive forms. Recently, research have been focused on vector control, which has been a huge success, at the price of neglecting the patients who already presented fixed and severe organic lesions due the chronic phase of the illness. This study focus on a rarely studied aspect of this pathology: the involvement of the lower urinary tract and it's symptomatology in adults suffering from Chagas chronic disease. Various studies have assessed the involvement of the lower urinary tract in chronic Chagas disease, the vast majority of them being on the animal model or very ancient human studies mainly on cadaveric specimen, the first of them being the primary description of Koeberle in 1963. Human symptomatology deriving from bladder, ureteral and urethral chronic chagasic lesions are yet widely unknown, and only a few Brazilian and Mexican studies have intended to describe the clinical and urodynamic presentation of these patients. The aim of this study is to assess the prevalence of urinary disorders in chronic chagasic patients and to describe their symptoms, through a complete clinical, ultrasonographic and urodynamic description.
The aim of this proposal is to evaluate the causal relationship between Zika virus (ZIKV) infections in pregnancy and congenital malformations. We will estimate the absolute and relative risks of congenital malformations and other adverse outcomes of pregnancy among women who become infected with ZIKV during pregnancy compared to uninfected pregnant women, also leading to further validation of the Congenital Zika Syndrome.
This protocol will compare topical paromomycin to standard intralesional (IL) antimony (Sb) to placebo for L braziliensis in Bolivia.
This feasibility study will be conducted at 4 international sites located in Asia (Dhahran, Nepal); Africa (Blantyre, Malawi and Kilimanjaro, Tanzania) and Latin America (Cochabamba, Bolivia). Each site comprises a cluster (including 3-4 health centers - 1 district hospital - 1 regional referral hospital) that service the population around the site area. Patients presenting at a health care clinic or hospital emergency department with signs and symptoms associated with high and moderate risk of developing AKI will undergo a point of care (POC) test to measure serum creatinine, saliva urea nitrogen dipstick (exclusively in Malawi), and a urine dipstick test for color, protein, glucose, blood and specific gravity. Patients who meet the study inclusion criteria will be approached for consent. Patients enrolled in the study will be followed throughout the health care evaluation and tracked through their course by location i.e. health care center, hospital, and home. Outcomes will be recorded through 6 months following the health care evaluation. The protocol will have an initial observation phase, during which relevant healthcare staff and the research team will be trained to identify patients at moderate or high risk of AKI and use of the point of care (POC) test for serum creatinine, saliva urea nitrogen dipstick (exclusively in Malawi), and urine dipstick test. During this phase patients will be tracked throughout the health care evaluation, however the teleconsultation will not be implemented and no specific guidance for managing the patient will be provided. During the subsequent intervention phase, the research team will interact with the local healthcare providers to and the teleconsultation physician, providing guidance on the management of the patient based on a standardized protocol. Protocols for patient care will be pre-specified, with minor adjustments to meet local requirements.
This randomised controlled trial will establish the effect a contraceptive intervention delivered by mobile phone app instant messaging on use of effective contraception in Bolivia. Woman aged 16-24 will be randomised to have access to Centro de Investigacion, Educacion y Servicios's sexual and reproductive health app (control) or the app plus 0-3 instant messages a day for 4 months (intervention). Participants will complete a questionnaire at baseline and 4 month follow-up.
In low-income areas worldwide, most patients with Parkinson's disease (PD) cannot afford long-term Levodopa therapy. A potential therapeutic option for them is the use of a legume called Mucuna Pruriens var. Utilis (MP), which has seeds with a high levodopa content (5-6%) and grows in all tropical areas of the world. MP powder is very cheap (total annual cost for a PD patient: 10-15 US $). The aim of this study is to assess efficacy and tolerability of acute and chronic use of MP compared to standard Levodopa therapy. The primary objective of this study is to investigate efficacy of acute levodopa challenge using MP in comparison to levodopa with a Dopa Decarboxylase Inhibitor (LD+DDCI) and without (LD-DDCI) and placebo. The secondary objectives are to investigate safety of acute intake of MP as well as efficacy and safety of chronic intake of MP over a 8-week period in comparison to usual LD+DDCI home therapy.
The study consists of two parts. Part I (CHICO) was designed to develop a better understanding of the efficacy, safety and pharmacokinetics of nifurtimox in children with a diagnosis of Chagas' disease (Trypanosoma cruzi infection) using pediatric formulations. Part II (CHICO SECURE) was designed at request of the FDA to assess the incidence of sero-negative conversion in children with diagnosis of Chagas' disease treated with nifurtimox.
Ranpirnase in topical formulation is an antiviral drug being evaluated for the topical treatment of anogenital warts. The aims of this study is to evaluate the efficacy and safety of a topical formulation of ranpirnase in subjects with genital warts.
The hypothesis is to evaluate if the treatment with Fexinidazole will lead to a better sustained clearance of the parasites at 6 months of follow-up when in comparison to placebo in patients with chronic indeterminate CD.
