There are about 11256 clinical studies being (or have been) conducted in Egypt. 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.

Current data estimated that 451 million people, (age 18-99 years) suffered from diabetes world wide in 2017, and are expected to rise to 693 million by 2045. Among them, type 2 diabetes mellitus (T2DM) accounts for around 90% of all cases with diabetes. T2DM is associated with several deterimental microvascular and macrovascular complications (Annani-Akollor ME et al ., 2019) . As such, effective management of the disease is crucial. The American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) recommend metformin as the first therapeutic choice for T2DM management with concurrent lifestyle modifications. Reports indicated that metformin improves peripheral insulin sensitivity and reduces the risk of cardiovascular mortality in T2DM in addition to its beneficial effects on weight loss and vascular protection. Nonetheless, as with most medications, metformin has some side effects. Though most of these side effects are mild, reports indicated that metformin use is associated with diminution of vitamin B12 level . Also, advanced age of patients with T2DM, nutritional deficiency, and malabsorption are other contributing factors for its deficiency . The proposed mechanisms for deficiency include, impairment of calcium dependent absorption from the gut, alteration in small bowel motility resulting in bacterial overgrowth, and a reduction in intrinsic factor levels . Metformin-induced vitamin B12 deficiency has also been associated with neuropathy. The neuropathy associated with vitamin B12 deficiency ranges from paresthesia and attenuated peripheral sensation in response to changes in mental status and proprioception which overlap with diabetic neuropathy. The progression of vitamin B12 deficiency-induced neurologic damage can, however, be abated through early detection and vitamin B12 therapy. Nonetheless, if peripheral neuropathy due to deficiency of vitamin B12 is misconstrued as diabetic peripheral neuropathy , permanent neurological damage may occur. Several studies have investigated the individual effects of the dose and duration of metformin therapy on vitamin B12 levels .The reported results are inconsistent, with some studies reporting an association with the dose but not the duration and other studies reporting an association only for the duration. however, A few studies did not find an association with either the dose or the duration.. This could be attributed to the fact that, in any given patient with T2DM, vitamin B12 levels could be influenced predominantly by either the dose or the duration of metformin therapy. Hence, it is important to involve both the dose and duration of metformin therapy into the assessment of vitamin B12 deficiency. Micronutrient deficiencies constitute a global health issue, particularly among countries in the Middle East .The World Health Organization (WHO) has divided this region into overlapping country clusters with regard to nutrition stages and dominant nutrition problems, including major risk factors and underlying causes, program interventions, and gaps in response to these problems. Countries in early nutrition transition (e.g., Egypt, Jordan, Lebanon, Morocco, and Palestine) are typically characterized by a moderate prevalence of overweight and obesity, moderate levels of undernutrition in specific population groups, and widespread micronutrient deficiencies/inadequacies. Metformin Usage Index is the product of the dose of metformin (mg) used and its duration divided by 1000. An index which incorporates both of these factors would not only be useful to understand the cumulative impact on vitamin B12 levels but also provide an objective threshold for initiating vitamin B12 supplementation . So , the aim of this study is to assess the relationship between the dose and duration of metformin therapy with vitamin B12 levels using the "Metformin Usage Index" (MUI) in Egyptian type 2 diabetic patients where the incidence of nutritional deficiencies are not uncommom in order to formulate their appropriate management strategies . The aim of our study is to evaluate the combined effect of both dose and duration of metformin therapy on vitamin B12 levels in Egyptian patients with type 2 diabetes mellitus (T2D).

Background and Aim: Breast carcinoma is the most common type of cancer and the most common cause of cancer-related mortality among women worldwide. Cancer stem cells (CSCs) are thought to be responsible for tumor initiation, progression, dissemination and resistance to chemotherapy and radiotherapy. CD133 is a trans-membrane glycoprotein which is considered as a putative CSCs marker. It has been extensively used as a stem cell marker for normal and cancerous tissues. Emerging evidence suggests that CD133 may be a critical factor in tumor development, progression and metastasis. The aim of this study was to evaluate expression status of CD133 in invasive ductal carcinoma (IDC) of the breast and its role during breast cancer progression and to correlate its expression with some known clinicopathological parameters.
The aim of this study is to examine whether Pulsed Electromagnetic Field therapy combined with strengthening exercises will have a positive effect on quadriceps muscle strength in lower limb burn .
Hyperglycemia is a major risk factor for the micro- and macro-vascular complications of diabetes . Lowering blood glucose levels has been shown to reduce the incidence of diabetes complications. Therefore, there is a need for a simple surrogate biochemical marker for glycemic variability. Glycated hemoglobin (HbA1c) is the standard clinical measurement used to monitor glycemic status and is recommended to assess control of diabetes over the preceding 2-3 months. However, being a measure of mean glucose, it does not reflect glucose variability. It is well known that insulin secretion defects of islet β cells and/or tissue insensitivity to insulin are common pathophysiological mechanisms of diabetes mellitus (DM) . The elevation in the blood glucose level usually represents the degree of glucose metabolism disorder, which is generally assessed by glycated hemoglobin A1c ( HbA1c) and indirectly reflects the extent of β-cell function damage . In the recent years, 1,5-anhydroglucitol (1,5-AG) has received attention as a short-term blood glucose index that reflects the average blood glucose level 1,5 AG reflects the average maximum blood glucose level during the past 1-2 weeks and is reported to be a more sensitive marker of glucose variability and postprandial hyperglycemia than HbA1c, even for patients with prediabetes and for those with well or moderately controlled diabetes . (1,5 AG ) is structurally similar to glucose . Due to this similarity, glucose inhibits renal reabsorption of 1,5 AG by competitive inhibition ,resulting in an inverse correlation of 1,5 AG with hyperglycemia . 1,5-AG levels are acting as an effective supplement to HbA1c. Additionally, previous study showed that 1,5-AG and HbA1c had opposite curves with increasing blood glucose levels; specifically, with the increase in HbA1c levels, 1,5-AG levels decreased significantly . Therefore, we speculate a ratio of 1,5- AG / HB A1C in relation to islet β-cell function and insulin resistance. The aim of our study was to evaluate the role of 1,5 anhydroglucitol and 1,5 anhydroglucitol / HbA1c ratio as a potential biomarker for islet β-cell function and insulin resistance among patients with type 2 diabetes .
uterine NK (uNK) cells are characterized by a high expression of CD56 (CD56brihgt), lack of CD16 expression, high secretion of cytokines and rather low cytotoxic activity. It has been shown that uNK cells increase in number during the late secretory phase and during early pregnancy. This study was designed to assess the possible role of uNK cells in repeated ICSI failure.
