Filter by:Diabetes Mellitus Type I is the chronic metabolic disease of childhood with the highest incidence in developed countries. Over the past 10 years the incidence of diabetes has been increased especially in immigrants children. The objective of the investigator's project is to evaluate factors that influence the T1DM course in immigrant and Italian children through an analysis of the relationship between socio-cultural determinants, lifestyles and metabolic control. The study population will consist of 100 children with first diagnosis of T1DM divided into two cohorts (Italian and immigrant children). The project consists in a follow-up of 18 months from first visit and will include laboratory tests, two questionnaires and determination of a microbiological indicator of the microbiota and levels of 25-hydroxyvitamin D. The research hypothesis is that the two groups of study population show a different metabolic control of diabetes due to differences in access to care, compliance to therapy and type of nutrition.
The primary aim of this randomized controlled trial is to determine if the integration of a Community Health Worker into the healthcare team is associated with an improvement in diabetes control in children with type 1 diabetes. The secondary objectives are to determine if utilization of Community Health Workers is also associated with reduced emergency department visits and hospitalizations, improved attendance at outpatient diabetes appointments, and improvements in psychosocial outcomes and diabetes control.
Due to early diagnosis (<20yrs of age) of Type 1 Diabetes, patients face longer duration of disease and greater glycemic exposure which makes them more vulnerable towards chronic complications. The aim of this study is to investigate the prevalence and incidence of micro and macro-vascular, pulmonary complications and patterns of growth failure in approximately 500 Type 1 Diabetes patients enrolled at Diabetes Unit, King Edward Memorial Hospital Research Centre. Then follow up of 100 participants who are above 15 years of age at baseline will be done after 2 years to document incidence and progression of complications. This will contribute in assessing the public health burden of complications of Type 1 Diabetes. Factors associated with prevalence of complications will be investigated. This risk factor analysis could aid in further modifying current prevention and treatment recommendations of these complications. Results of this study could modify current clinical practice.
The purpose of this study is to evaluate whether the administration of multipotent stromal cell also referred as to mesenchymal stem cells (MSCs), modified Type 1 Diabetes progression.
This study will test the hypothesis that a BAC (blood alcohol content) of 0.1% will not significantly alter the anti-hypoglycemic effect of mico-dose glucagon in individuals with type 1 diabetes.
The purpose of this study is to use an Advisory/Automated Adaptive (AAA) Control system for insulin delivery in adults with Type 1 Diabetes (T1DM) in an outpatient setting to evaluate the system's ability to significantly improve blood glucose levels. This protocol represents a culmination of prior clinical trials in development of this AAA control system and benefits from the synthesis of those components.
BACKGROUND. Optimal glucose control can prevent/relent tissue damage in patients with type 1 diabetes mellitus (T1DM). Ongoing efforts aim at developing closed loop control (CLC) algorithms linking subcutaneous continuous glucose monitoring (CGM) and insulin delivery (CSII). Substantial improvement towards an effective artificial pancreas system is still needed, especially in the regulation of post-meal glucose. Application of metabolic control analysis (MCA) can unveil and quantify distortions in the system properties of the glucose-insulin (pump) system (GIS), by measuring the coefficients of control (CCs) of glucose. Our approach rely on previous experience with our previous pilot protocol (NCT01800734). AIM. We will outline and compare features of GIS in T1DM patients and in healthy controls during differently sized breakfast meals and during 24-hour periods. The reproducibility of our approach will also be assessed. METHODOLOGY. Three protocols will be carried out. All T1DM patients will be on CGM/CSII therapy. In all three protocols, study 1 will be an euglycemic insulin clamp in T1DM patients and a frequently sampled intravenous glucose tolerance test (IVGTT) in healthy controls. - Protocol 1: 10 T1DM patients on CGM/CSII and 10 control subjects will ingest a mixed meal of different size (320 and 640 kcal) on two separate occasions. - Protocol 2: 5 T1DM patients will ingest two repeat 320 kcal meals, whereas other 5 T1DM patients will ingest two 640 kcal meals on two separate occasions. - Protocol 3: 10 T1DM patients and 10 controls will be monitored for 24 hours, during which they will ingest 3 mixed meals. Substrate (including CGM)/hormone responses will be measured in all studies. Comprehensive single meal and 24-hour models of GIS will be built, MCA will be applied and the CCs of glucose assessed, thereby allowing to outline and to compare the CCs of glucose between patients and controls. EXPECTED RESULTS. Our data will be of use in devising novel clinical strategies in T1DM, including, but not limited to, development and refinement of CLC algorithms along the path towards an effective artificial pancreas system.
City of Hope National Medical Center, located in Duarte, CA, is hosting a clinical study on islet cell transplantation, an experimental procedure being evaluated as a treatment for patients with type 1 diabetes. Islet cell transplantation involves taking insulin-producing cells from organ donors and transplanting them into the liver of a patient with diabetes. Once transplanted, the islets produce insulin, which can improve blood sugar control and eliminate the need to inject insulin or use an insulin pump. Anti-thymocyte globulin (ATG) and alemtuzumab (Campath) are anti-rejection medications that work by decreasing a patient's T-cells. T-cells are special white blood cells that recognize and destroy unwanted things like infections but can also attack transplanted cells and organs. Reducing the number of T-cells at the time of transplant may protect islets and improve long-term transplant success. In previous research studies, islet transplantation has been successful in reducing low blood sugar episodes, improving overall blood sugar control, and in some cases, allowing patients with type 1 diabetes to stop taking insulin. The purpose of this study is to determine if islet cell transplantation using ATG or alemtuzumab, along with additional medications to prevent the body from rejecting the transplanted cells, is a safe and effective treatment for type 1 diabetes. Study participants may receive up to three islet transplants and will be followed for five years to monitor blood sugar control, islet transplant function, and changes in quality of life.
Umbilical mesenchymal stem cells (UC-MSCs) infusion is supposed be a promising regeneration therapy with mild side effect as indicated by large quantities of animal experiments and some clinical trials. There are few UC-MSCs clinical trials with regard to diabetes mellitus. The investigators hypothesize that infusion of USC-MSCs may provide multiple signals for beta-cell regeneration and even re-differentiate into local tissues in diabetes mellitus patients, resulting in improvement of diabetic control, of which the effect may be promoted by concomitant infusion of bone marrow mononuclear cells and maximized by intra-arterial pancreatic infusion through angiography.
This study will look at the treatment effect of DiaPep277 on preservation of beta-cell function, as defined by meal-stimulated secretion of insulin. DiaPep277 is a peptide that changes the way the immune system behaves, stopping its attack on the beta-cells. Adults (>20 years) with newly diagnosed (<6 months) type 1 diabetes will be treated with 10 injections of DiaPep277 or Placebo over a 2-year treatment and follow-up period.
