Active clinical trials for "Diabetes Mellitus, Type 1"

The objective is to determine if lowering serum uric acid by means of allopurinol in the course of kidney disease may be effective in preventing or improving albuminuria and renal function in Type 1 Diabetic patients. The study is a double blinded, randomised, placebo-controlled cross-over clinical trial.

The investigators are conducting a prospective cross-over study to evaluate the effects of vitamin D supplementation on diabetes control and the pro-inflammatory markers involved in microvascular complications in adolescents with Type 1 Diabetes. The investigators expect to see a significant improvement in glycemic control and a reduction of serum pro-inflammatory markers in adolescents with Type 1 Diabetes and vitamin D deficiency or insufficiency, who are treated with vitamin D.

Adolescents with type 1 diabetes are at increased risk for depressive symptoms, poor coping and problem-solving skills, poor regimen adherence, and negative diabetes-specific health outcomes. Although a handful of psychological interventions targeting adolescents' poor behavioral and emotional functioning demonstrate beneficial effects on disease management and outcomes, no prevention programs exist that equip adolescents with behavioral skills and cognitive strategies necessary to reduce these risks. Therefore, the proposed research will test whether a diabetes-specific adaptation of a resilience promoting, depression-prevention intervention for adolescents with type 1 diabetes will reduce both the risk of poor psychological functioning and the risk of negative health outcomes over time.

Type 1 diabetes mellitus (T1D) results from immune-mediated destruction of insulin-producing islet cells. The loss of islet cells is traditionally treated with insulin therapy and in some cases pancreas or islet cell transplantation. Another approach would be to preserve islet cell mass before it is irreversibly lost. Previous trials using immune suppression within 6 weeks of T1D onset have demonstrated diminished exogenous insulin requirements compared to untreated controls. In our prior phase I non-randomized study, by extending immune suppression to the point of immune ablation / immune reset with autologous HSC support, several patients with new onset T1D have maintained an insulin-free, drug free remissions for more than 4 years. Although these results appear highly promising, it may be argued that our results are mitigated by the documented honeymoon effect following T1D, that is by a normal transient insulin free interval occurring after disease onset in some patients. The goal of this trial is to extend this phase I study of new onset T1D to clarify whether our post transplant insulin free interval is due to treatment intervention (transplant) or a result of a normally occurring "insulin free honeymoon period". Both groups will receive identical change of life style (i.e. diet, exercise) education.

We aim at establishing a research program that will offer screening for the presence of Islet Autoantibodies (IA) in relatives of people with Type 1 Diabetes (T1D). Relatives of people with diabetes, children, and adults from our clinic and all over Israel will be offered to participate in the study. The presence of IA will be evaluated using the Detection by Agglutination-PCR (ADAP) technology developed by Enable Biosciences, which is 1,000-10,000 times more analytically sensitive than currently used methods.. When positive in the screening, multiple antibodies will be confirmed by a second sample analyzed by the ADAP technology and by a radio binding assay (RBA). People positive for one or more antibodies (stage 1 or 2 T1D) will be referred to attend an educational program at our center. This program will include diabetes education emphasizing DKA prevention as well as stress assessment for the families involved and stress alleviating interventions. After the educational visit, people at risk of developing diabetes will be referred to further follow-up and evaluation under routine medical care at our center.

The objective of this observational study is to predict healing at 26 weeks after the first visit in patients affected by the first ulcer, by means of combined data monitoring of Laser Speckle Contrast Imaging (LSCI) and temperature measurements during patient visits in hospital. In order to achieve this objective, study aims to produce a logistic regression model and then evaluate its prognostic ability by means of the area under the curve (AUC) of the receiver-operating-characteristics (ROC) curve. Patients with diabetes mellitus and suffering from ulcer and receiving health care will undergo regular microcirculatory measurements including LSCI scans in and around the ulcer location and thermography.

The aim of the study is to analyse the biomechanical stiffness of red blood cells extracted from subjects with type I diabetes with and without microvascular complications through a biophysical characterization of red blood cells using microscopy, spectroscopy and scattering measurements. 48 subjects with type 1 diabetes, 24 with and 24 without microvascular complications will be enrolled. From all subjects a single blood sample will be taken to perform the analysis of red blood cells morpho-mechanical properties.

Type 1 diabetes is associated with many longterm complications as retinopathy,neuropathy and nephropathy. Recently, several studies have linked type 1 diabetes to bone fragility.Studies conducted on patients with type 1 diabetes have concluded that bone is negatively affected in type 1 diabetes with impaired bone density,increased fracture risk and impaired bone turnover markers.

For last decade, the innovation of mobile health platform has brought new opportunities for disease management. Previous studies have shown that health management programs based on mobile platforms for patients with diabetes can improve patients' glucose control, self-management ability and quality of life. Type 1 diabetes mellitus (T1DM) due to its characteristics needs long-term linkage care throughout the lifespan cycle of patients. Therefore, this study intends to construct a prospective and open T1DM cohort based on mobile application and platform, to deliver home-community-hospital joint management for patients, and to provide follow-up online or offline every 3 months lasting for 10 years. Mainly, the objective of this study is to observe the blood glucose control outcome of T1DM patients. Secondly, the control of comprehensive metabolic indicators such as blood pressure and blood lipid, occurrence and progression of acute and chronic complications, and psychosocial status were included as well, expecting to provide scientific evidence for continuously improving the quality of T1DM management.

The purpose of this study is to determine if prolonged administration of the anti TNF (tumor necrosis factor)-Alpha agent etanercept is associated with enhanced graft survival in patients undergoing islet after kidney transplantation.
