There are about 72 clinical studies being (or have been) conducted in Jamaica. 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.
Sickle Cell Anemia is caused by an inherited hemoglobin disorder. Healthy red blood cells are discoid and can deform and move through small blood vessels to carry oxygen to all parts of the body. In sickle cell disease, as red blood cells circulate and oxygen is released in the circulatory system, the deoxygenated abnormal hemoglobin S can begin to polymerize. When this occurs, the red blood cells can become sticky and elongated. These sickled red blood cells are less flexible and will obstruct small blood vessels and block normal red blood cells from traveling through the circulatory system, which limits oxygen delivery to tissues and organs. This is known as a "sickle crisis". Patients suffering from a sickle crisis experience severe pain and are at risk of stroke, heart attack or even death. By lowering the level of oxygen pressure at which sickling occurs and opening the vasculature and rapidly delivering oxygen directly to ischemic tissues, the addition of MP4CO to existing treatment protocols may alleviate pain associated with a sickle cell crisis, abort a crisis and/or potentially reduce the duration of a crisis. This could mean less time in the hospital and an improved quality of life for patients with sickle cell anemia.
To determine the efficacy of high dose folic acid supplementation for prevention of preeclampsia in women with at least one risk factor: pre-existing hypertension, pre-pregnancy diabetes (type 1 or 2), twin pregnancy, preeclampsia in a previous pregnancy, or body mass index ≥35. It was hypothesized that high dose (4.0 mg per day) supplementation starting in early pregnancy and continued throughout the entire pregnancy will lower the incidence of preeclampsia in pregnant women at high risk of developing preeclampsia.
The purpose of this study is to evaluate the safety and tolerability of three dose levels of HQK-1001 administered once daily for 26 weeks in subjects with sickle cell disease.
To evaluate the efficacy and safety of sifalimumab compared to placebo in subjects with moderately to severely active Systemic Lupus Erythematosus (SLE).
Intervention to investigate the efficacy of a nutritional supplement among ARV-naïve, asymptomatic HIV positive patients with a CD4 count in the range 300-550 cells/ul.
There are no evidence (research) based guidelines for treatment of early, closed puncture wounds of the feet in diabetics. Surgeons usually see only the limb- and life-threatening consequences of puncture wounds of the feet in diabetics, and are therefore tempted to advocate more aggressive, preemptive, invasive primary treatment for all such wounds, assuming, from this blinkered perspective that all such wounds progress to serious infection. This study is designed to determine the natural history of puncture wounds of the feet in diabetics, specifically, whether all become infected or whether some do heal without any surgical intervention. It requires administration of a questionnaire to 188 known diabetics attending 11 selected outpatient health care centers in the parish of St. James, Jamaica.
The purpose of this study is to assess the safety and tolerability of HQK-1001 administered for a total of 12 weeks (with one dosing break) in subjects with sickle cell disease.
The purpose of this study is to determine whether low and intermediate GI Caribbean foods are effective in the management of type 2 diabetes.
This research may explain whether a shortage of three special compounds called aromatic amino acids is responsible for the severe illness and high death rate of children with the kwashiorkor type of malnutrition and whether supplying adequate amounts of these compounds in the treatment diet will speed up recovery from this condition. We propose that decreased availability of the aromatic amino acids may be the reason why children with kwashiorkor are sicker and more difficult to treat.
To determine whether hyoscine butyl bromide is effective in shortening the first stage of labor, with no increase in maternal or neonatal complications.
