There are about 1926 clinical studies being (or have been) conducted in Colombia. 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.
SARS-CoV-2, the virus that causes COVID-19, is currently a global public health problem, declared a pandemic by the World Health Organization, which today has more than one million deaths in the world, of which , 30,000 approximately belong to Colombia, being the country number 11 with the highest number of deaths. The most common symptoms related to this disease are fever, cough, dyspnea, myalgia, headache, diarrhea and rhinorrhea. COVID-19 is characterized by immune system dysfunction and hyperinflammation causing acute respiratory distress syndrome, macrophage activation, and coagulopathy. The clinical course for SARS-CoV-2 in most cases is mild, but approximately 14% of cases can be severe. In pneumonia caused by SARS-CoV-2, the lung lining is known to alter the composition of the lung microbiome, in addition to lymphocyte damage that can promote the growth of bacteria to initiate bacterial pneumonia, and it is estimated that the prevalence of coinfection / superinfection reaches 50% among deaths from COVID-19. Coinfection between different microorganisms and SARS-CoV-2 is a serious problem in the COVID-19 pandemic, and there is still little information on this. It is for this reason that the researchs propose to develop this research project that will allow to understand the possible mechanisms associated with the development of bacterial coinfection / superinfection in patients diagnosed with COVID-19, which will allow expanding the panorama of knowledge towards a better and adequate treatment in these patients, as well as detection of biomarkers or clinical phenotypics that may be useful in the diagnosis, based on evidence. It is important to note that these results are of clinical importance since we will try to identify biomarkers or changes in the lung microbiome that allow doctors to early identify patients at risk of developing coinfection and thus initiate early treatments or preventive measures, which allow the improvement of clinical outcomes in patients. Results will be presented in a timely manner at national and international conferences and in peer-reviewed, indexed, high-impact journals.
This is a randomized, double-blind, controlled, which seeks to compare two groups of volunteers (naive and previously exposed to malaria) vaccinated with three doses of a synthetic derivative of the CS protein of Plasmodium vivax to determine their protective efficacy. Then volunteers will be subject to an infectious challenge (Controlled Human Malaria Infection) to assess the infectivity of gametocytes in the blood early stage of P. vivax in Anopheles albimanus mosquitoes.
To evaluate the effectiveness of pain reduction on a initial orthodontic treatment by using 810nm Diode laser compared to a placebo. Methods: This study will include two parallels groups, 30 adult patients each (mean age 18 - 40) that will be asked to fill a questionnaire related with pain before starting orthodontic treatment with Tip edge technique. Patients from one of the groups will receive laser therapy on both upper and lower maxillary according to the protocol. The patients from the other group will receive a placebo simulating a laser therapy on both maxillary. After the process, both groups will be checked on different times (12hrs-24hrs-48hrs-72hrs after) by filling a questionnaire related with pain each time.
The aim of this study is to evaluate in a clinical trial a rehabilitation device for patients with obstructive sleep apnoea (OSA) based on oropharyngeal electrical stimulation, which strengthens the dilating muscles of the upper airway, improves mechanical laryngopharyngeal sensitivity and improves OSA. Furthermore, to perform experimental electrotherapy, nasoendoscopy, polygraphy and polysomnography tests with the device in order to calculate thresholds of functional and sensory intensities on the dilating muscles of the upper airway in patients with OSA. These tests also include the detection of signals that measure breathing events during sleep in patients with OSA in order to use them in the control mechanisms of the electrostimulation device. Assess the effects and safety of the device in a group of five healthy volunteers for preliminary results. Finally, to evaluate in a small group of patients with OSA the device capacity to stimulate the upper-airway dilating muscles and to reduce the Apnea-Hypopnea Index (AHI) and oxygen desaturation indices when the electrostimulation device is used over a medium-term period (eight weeks) with morning and evening therapy sessions.
Motor development of the premature infant often exhibits deviations that trigger functional limitations and disability. In Colombia, one out of every five births corresponds to premature babies. In preterm infants requiring hospitalization, early clinical interventions focused on home care have been shown to improve motor development and decrease morbidity. However, interdisciplinary work, supported by information and communication Technologies (ICT), shows a knowledge gap that can be explored. This leads to the following research question: What is the effect of the Interdisciplinary Hospital-Home Intervention on the adaptation of the motor development of premature children compared to traditional intervention in Colombia and Polonia? Objective: To determine the effect of the interdisciplinary Hospital-Home intervention on the adaptation of the motor development of premature children compared to traditional intervention in Colombia and Polonia Methodology Experimental quantitative study with pre-test and post-test to two groups, experimental and control, which compares before and after the intervention. The intervention will be developed in two scenarios: the hospital and the home. The experimental group will receive the intervention and the control group the traditional care established in the institutions for premature children. The calculation of the sample size is 130 participants. Type of results expected to be obtained It is expected to obtain a supported that justifies the importance of education from hospital stay, post discharge follow-up and parental participation in the adequate stimulation of motor development of the premature. It is expected to incorporate the use of ICT in home monitoring, while implementing the use of a mobile application for this purpose. It is also expected to contribute to the research training of undergraduate and graduate students. In addition, participate in national and international presentations and in the production of scientific articles.
It will be performed a randomized, multicenter, triple-masked, placebo-controlled clinical experiment to determine the effectiveness and safety of the administration to of ivermectin at a dose of 200 mcg/kg once a week for 7 weeks in a prophylactic treatment against SARS COV-2 infection in 550 Colombian health workers during the COVID-19 pandemic.
Introduction: The SARS-CoV-2 outbreak has left more than two million infected worldwide in the first four months of COVID-19 epidemic. To date, there is no specific treatment for the disease and in critically ill patients there is an additional challenge in controlling the systemic inflammatory response, which is characterized by cytokine storm, alteration in coagulation and endothelial activation in addition to infection. Strategies used in previous viral epidemics, such as convalescent plasma, are therapeutic options to rescue, especially in individuals with a critical presentation of the disease. Aim: To establish clinical response of critically ill patients with COVID-19 who received convalescent plasma from subjects recovered from SARS-CoV-2 during their stay in Intensive Care Unit at Fundación Cardiovascular de Colombia (Hospital Internacional de Colombia). Methodology: Quasi-experimental study (no randomization will be performed). Adult patients who meet selection criteria will receive 500 ml of ABO compatible convalescent plasma, obtained by apheresis from patients recovered from SARS-CoV-2 infection. The main outcome will be in-hospital mortality at 30 days, while indication for ventilatory support (intubation) and adverse events at thirty days will be evaluated as secondary outcomes, compared to subjects receiving usual treatment for clinical sign and symptoms given the absence of ABO compatible plasma units. A survival analysis will be performed using Kaplan-Meier method and association strength will be reported using HR and 95% CI crude and adjusted for confounding variables. Expected results: It is expected to know the clinical and paraclinical response of patients receiving convalescent plasma in our institution, as well as to establish their probability of survival and its associated factors.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected the global population with significant morbidity and mortality. One of the main concerns is the management of the patients since there is no specific treatment for this condition. Therefore, in SARS-CoV-2 patients the compassionate use of off-label therapies has been initiated; such as the use of plasma from convalescent patients. This treatment has been used in other pandemics like SARS-CoV-1, H5N1, H1N1, Ebola, among others. This study is a phase II/III randomized clinical trial to assess the effectiveness and safety of convalescent plasma administration in patients with high-risk SARS-CoV-2.
A randomized, open-label, multicenter, three-arm clinical trial to study the efficacy and safety of passive immunotherapy (convalescent plasma and anti-COVID-19 human immunoglobulin) compared to the standard treatment in Colombia.
Convalescent plasma has been used for over 100 years in the treatment of severe acute respiratory infections of viral origin. There are not pharmacological treatments for the actual outbreak for SARS-Cov-2 and it is necessary to evaluate the efficacy of treatment options, including convalescent plasma transfusion. The hypothesis is that convalescent plasma is efficacious and safe for reducing mortality in patients with COVID-19 treated in ICU
