Active clinical trials for "Diabetes Mellitus"

The main objective of this study is the objective evaluation of disease related sleep fragmentation in subjects with type 1 diabetes.

By Jan 7, 2020, Chinese scientists had isolated a novel coronavirus, from patients with virus-infected pneumonia. The WHO designated later this virus as COVID-19 (coronavirus disease 2019). This exponential pandemic coronavirus infection is responsible for severe forms in 15 to 20%, for critical ill requiring ventilation in 5% and for mortality in 2%. Algeria was part of the 13 top priority countries identified by WHO based on their direct links and volume of travel to the infected provinces in China. It is known that some predisposing conditions lead to a worse outcome with coronavirus. In China, the overall case-fatality rate was 2.3%, but was higher in patients with diabetes (7.3%). In Italy, the most common comorbidities associated with death from COVID-19 were hypertension (73.8%) and diabetes (33.9%). The US Centers for Disease Control and Prevention suggests diabetes is the most common comorbidity in COVID-19 cases. In the largest cohort NHS England study, death from COVID-19 was strongly associated with uncontrolled diabetes (after full adjustment, HR 2.36). The West Algerian CORODIAB-13 study aims is (1) to assess the prevalence of diabetes among hospitalized patients with Covid-19, (2) to describe the phenotypic characteristics of patients with diabetes, and (3) to identify the parameters specific to the diabetic which are associated with severe forms. In the future, this study will provide answers for two main questions Why diabetics are more at risk of developing Covid-19 infection? Why diabetics are at high risk of developing severe forms?

Personalized medicine methods in the management of type 1 diabetes

The aim of this work is to demonstrate the variation of Diabetes mellitus either preexisting or gestational Diabetes mellitus among pregnant ladies in our localities, detect maternal & fetal complications and to predict the risk factors for poor maternal, fetal & neonatal outcomes

The aim of this study is to to analyze if it is possible to reach the goals of HbA1c <7.0% and blood pressure <= 130/80 mm Hg in a cohort of patients with type 2 diabetes attending a primary care unit, using ony those resources available at the unit, and provided by the Brazilian National Health System. It is an open label, observational study, with a duration of 4-6 years. Patients attending a primary care outpatient facility will be sequentially included in the study provided they give consent. They will be followed on a monthly basis by a team of physicians and nurses. Glucose, A1c, Blood PRessure will be the outcomes.

The purpose of this study is to assess the glycemic response to cycling road races (using continuous glucose monitoring ) in elite athletes with type 1 diabetes and non-diabetic controls. The investigators will also assess the relationship between power/work during cycling (using a power meter) and the subject's glucose profile.

In order to evaluate the potential role of the gastrointestinal (GI) tract in the postprandial hyperglucagonemia, which characterizes type 1 diabetes mellitus (T1DM) (as well as type 2 diabetes mellitus (T2DM)), we wish to investigate the secretion of glucagon in patients with T1DM without residual beta-cell function during 50-g oral glucose tolerance test (OGTT) and during isoglycemic iv glucose infusion. By evaluating C-peptide negative patients with T1DM we aim to describe the glucagon response to glucose (+/-stimulation of the GI tract) independently of the potentially very important regulation of glucagon secretion by endogenous insulin secretion. A more detailed understanding of the inappropriate glucagon secretion in T1DM is highly needed in order to establish new intervention strategies in the future treatment of the growing numbers of T1DM patients.

The aim of the study is to find out prevalence of diabetic macular edema (DME) in patients with diabetes mellitus in Slovak Republic.The outcome of the project will be epidemiology survey, prevalence of wet form of Diabetic Macular Edema in relation to duration of diabetes, type of diabetes, treatment (insulin vs. OAD or combination) etc. and identification of prognostic factors leading to development of DME.

Comparison of noninvasive glucose measurement performance versus standard invasive reference measurements.

Pregnancies of patients with Diabetes are associated with increase adverse pregnancy outcome . The risk for vascular complications including: Intra uterine growth restriction (20%), hypertension (31%), preeclampsia (15%), eclampsia and placental abruption are significantly greater than those in background populations. The risk of developing vascular complications in diabetes pregnancies although is correlated with the severity and length of the disease is not fully understood. Enhanced oxidation has been suggested to be the underlying abnormality responsible for some of the complications of diabetes. Haptoglobin (Hp) is an abundant plasma glycoprotein produced in the liver. The best understood function of Hp is to bind free hemoglobin (Hb) released from red blood cells. Extracorpuscular Hb is a potent Fenton reagent.capable of of inflicting oxidative tissue damage. Hp binds to Hb and serves to inhibit the oxidative potential of Hb by preventing the release of heme iron. The haptoglobin (Hp) gene at chromosomal locus 16q22 is polymorphic, with two common alleles denoted 1 and 2. the prevalence of Hp 1-1, Hp 1-2 and Hp 2-2 genotypes is approximately 16%, 48% and 36%, respectively. In the western world. A total of five independent longitudinal studies have demonstrated that DM individuals with Hp 2-2 genotype have a two to five-fold increased risk of CVD as compared to DM individuals without the Hp 2-2 genotype We sought to determine whether HP genotype plays important role in development of vascular complications in pregastational pregnancies. and whether Hp genotype 2-2 is a risk factor for developing gestational diabetes (GDM)
