There are about 98 clinical studies being (or have been) conducted in Qatar. 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.
NSAIDs are commonly used in the management of acute pain; Diclofenac is one from the same class. It is an amino phenyl acetic acid derivative which inhibits prostaglandin biosynthesis to produce analgesic, antipyretic and anti-inflammatory effect. The drug efficacy and safety in acute pain management has been proved by several studies like in renal colic, post and pre-operative pain management, migraines etc. It's also known to have an opioid-sparing effect. Mode of administration is one of the important factors to consider in a busy emergency room. Perception about the route of administration differs among patients. As believed,injectable have rapid onset, easier to titrate, and patients respond better to them as they consider them stronger than oral medication. Number of trials has compared oral and parenteral NSAIDs. Most found no benefit to the parenteral route. Considering the limitations of the previously done studies like small sample size, heterogeneity in the group of patients enrolled, improper blinding and comparing of two different drugs from the same class. Therefore, aim of the study is to conduct a Double blind randomized clinical trial to assess the clinical efficacy and pharmacokinetic parameters of oral diclofenac compared to intramuscular diclofenac in patients with acute limb injury. In this two group double blind randomized clinical trial, the clinical efficacy and pharmacokinetic parameters among the two groups will be assessed. Eligible patients visiting to HGH-ED, age (above 18 years) with acute limb injury, having moderate to severe pain (defined as pain score of >=4 on Numerical rating scale) will be recruited. With the use of computer generated block randomization, subjects will be allocated to one of the two treatment groups in the ratio of 1:1. Each group will receive either (intramuscular diclofenac / oral placebo) or (oral diclofenac / intramuscular placebo). Among the 300 subjects enrolled for the study, further stratified randomization will be done in order to enroll 20 patients for pharmacokinetic study within the subjects.High-performance liquid chromatography, method will be used for the determination of drug concentration in human plasma, for detailed pharmacokinetics. The pain score will be assessed by using the validated pain scale i.e. Numerical rating scale (NRS). The participants, clinicians and investigators will be masked to treatment assigned and the results will be analyzed by the intention to treat analysis among the two group treatment.
The proposed research aims to study the effects of antioxidant therapy, commonly used in male infertility treatment, on semen analysis. Patients presenting with male infertility, who are found to have abnormal semen analysis shall be recruited to this study. They will be asked to provide a sample of semen for routine semen analysis and advanced semen tests including sperm DNA fragmentation and sORP before starting with antioxidant therapy and after 3-month treatment with antioxidants. After completing the data analysis, we intend to publish the study in high impact perr reviewed journals and present it in international conferences.
Coronary heart disease (CHD) poses a major health burden in the Gulf countries. It is the leading cause of mortality and morbidity in the world and poses an enormous societal burden in the Gulf countries. Early detection of disease is imperative to reduce the health care burden and financial costs associated with CHD. Knowledge of novel genetic and proteomic markers of CHD will provide more precise estimates of risk while defining the pathways important in individual patients, revealing new targets for intervention, and ultimately enabling an individualized approach to care. To translate recent advances in genomics and proteomics into clinical practice, these newly discovered biomarkers will need to be evaluated in patients of diverse ethnic groups with varying characteristics, environmental factors, and medication use. The investigators propose to establish a biorepository of plasma and Deoxyribonucleic acid (DNA) linked to demographic and clinical variables to facilitate biomarker studies of CHD risk, progression, and outcome. The overarching goal in developing the Qatar Cardiovascular Biorepository (QCBio) is to create a resource that fosters research aimed at identifying novel biochemical and genetic markers of CHD. A biorepository with linkage to clinical data will also provide an invaluable resource for cardiovascular research, including genomic and proteomic studies of CHD and development of biomarkers for early detection of disease and personalized drug therapy (pharmacogenetics and pharmacoproteomics).
Type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) are closely related. T2DM risk equivalent for CVD and it remains the major cause of death in T2DM. Thus, patients with T2DM and CVD disease are at very high-risk of CVD-related mortality. Therefore, more aggressive metabolic and hemodynamic control is required in such patients to improve the prognosis. We recently initiated a cardio-metabolic clinical service at the Heart Hospital, where T2DM patients with existing CVD are simultaneously examined by Cardiologist and Diabetologist for optimal metabolic and hemodynamic control. We would like to start a clinical registry for all patients who attend this clinical service to collect import clinical data about this population. This registry will serve an important source for future clinical research in the field.
SevEos is a cross-sectional, multi-center, non-interventional study aimed to describe the treatment patterns in 250 severe asthma patients across the Gulf region. In addition, the study will determine the current level of asthma control and quality of life in these patients; describe the exacerbation patterns; and determine the current levels of blood eosinophils for the enrolled patients.
Despite recent medical advances, sepsis and septic shock remain a major cause of death. Sepsis is a syndrome with a wide array of physiologic, pathologic, and biochemical abnormalities. Several studies have shown vitamin C have decreased the circulating pro-inflammatory cytokines and oxidative stress.Thiamine had favorable effects on pro-inflammatory cytokines, oxidative stress and cellular hypoxia.The use of hydrocortisone in combination with vitamin C will increase the transport of vitamin C into the cells; since the pro inflammatory cytokines have shown to decrease the expression of the sodium-vitamin C transporter-2 (SVCT2) while glucocorticoids increase the SVCT2 expression. A recent small retrospective study , showed a significant decrease in mortality when patients with severe sepsis and septic shock are treated with a combination of Hydrocortisone, Vitamin C, and Thiamine. Conducting a similar study with a prospective randomized design will give clinicians all over the world more answers and will help clinicians to provide better care to millions of patients using highly safe therapeutic regimen. The objective of the current study is to explore the clinical benefits of using a combination of hydrocortisone, vitamin C, and thiamine (triple therapy) for the management of septic shock. To achieve this objective, we will compare two alternative treatment strategies, either triple therapy or usual care in patients with septic shock. First aim: To assess the effectiveness of the triple therapy for septic shock Second aim: To assess the safety of triple therapy
This is a study to be performed in Qatar that will look at the comparison of glycemic control in patients with type 2 diabetes on insulin glargine U100 with insulin degludec over the Ramadan period, to determine whether better glycemic control with fewer hypoglycemic episodes can be achieved.
The primarily goal of the research is to better understand progression of disease in patients who present with an acute stroke to the Hamad General Hospital (HGH) stroke and Transient Ischemic Attack (TIA) clinic. The investigators are specifically interested in patients who have diabetes and have a stroke. The patients enrolled into the research will have detailed clinical evaluation and their imaging studies (MRI and Doppler) will be reviewed. After informed consent, subjects will be examined in the stroke Ward /TIA clinic upon recruitment, and later at less than 48 hours of recruitment (blood extraction and urine samples) and for follow up visits at 1 month+/-7 days (clinical evaluation and to extract blood and urine samples), at 3 months (telephonic conversation only) and at 1 year (clinical and repeat MRI brain). During the initial visit at the ward the investigators will collect serum and plasma for proteomic and metabolomic studies. These will be repeated at less than 48 hours and at 1 month+/-7 days. Investigators will test the effects of risk factors such as diabetes/stroke on the endothelial procoagulant and inflammatory state at onset and evaluate if best medical control leads to improvement in such markers.The repeated studies will determine if better management and presence of certain blood biomarkers can predict or translate to slower progression of disease and correlate it with clinical status.
Diabetes is one of the greatest challenges faced by healthcare services worldwide. It is associated with serious complications such as heart attacks, stroke, and peripheral artery disease as well as kidney disease, eye disease, and nerve dysfunction. Data from weight loss with bariatric surgery suggest that with the appropriate intervention, it should be possible to reverse diabetes and that the earlier the intervention occurs, the greater the chances of placing diabetes into remission. There is now a need to translate this knowledge into the medical care of younger patients with early diabetes who are overweight/obese. The aim of this study is to see if younger adult patients with overweight/obesity and type 2 diabetes who are participants in a programme incorporating a low energy diet and physical activity (lifestyle) will lower their weight, cardiovascular risk and improve their glycaemic control as compared to the usual care.
Diabetic kidney disease (nephropathy) develops in nearly 40% of patients with type 2 diabetes mellitus. Diabetic nephropathy is caused by damage to the small blood vessels in the kidneys due to uncontrolled blood sugar levels, which mean that the kidneys become less effective at filtering urine. This is associated with albuminuria (protein in the urine). Treatment with some drugs reduces the loss of albumin through the urine and delays disease progression. There is increasing evidence that vitamin D could also be important in management of diabetic kidney disease. The aim of this study is to investigate the efficacy and safety of a combined regimen of calcitriol (active vitamin D) and established drugs for diabetic kidney disease.
