Novel Therapy to Preserve Beta Cell Function in New Onset Type 1 Diabetes

Diabetes Mellitus Type 1Autoimmune Diabetes

Background: Type 1 diabetes (T1D) occurs when the immune system attacks insulin-producing cells (beta cells) in the pancreas, resulting in their death. Insulin injections currently are the best method for controlling blood sugar in individuals with T1D. However, animal studies have shown that the drugs sitagliptin and lansoprazole can help reverse beta cell damage or develop new beta cells. In addition, Diamyd has been shown to weaken the immune process that attacks pancreatic beta cells. Objectives: To find out whether a combination treatment of sitagliptin, lansoprazole, and Diamyd will help maintain functioning beta cells and/or cause new beta cells to form. To determine how the drug combination affects insulin doses and blood sugar control. To determine whether the drug combination affects the immune response involved in T1D.

Comparison of Histamine and Local Heating for Evoking the Axon-reflex Flare Response in Diabetes...

DiabetesDiabetes Mellitus3 more

Diabetic peripheral neuropathy is the most common complication to diabetes mellitus affecting as much as 50% of the population with diabetes. Symmetrical sensory neuropathy is by far the most common pattern, which often progress slowly over many years, although some individuals experience faster and more severe courses. Despite the frequent occurrence, the causes of diabetic peripheral neuropathy are largely unknown, which is reflected in the fact that no disease-modifying treatments are available for preventing, treating or even halting the progression of the disease. The consequences can be dire, as neuropathy frequently leads to foot ulcers, amputations or intolerable neuropathic pain in the lower extremities. Sensory loss may go completely undetected in diabetes, as there often are literally no symptoms. For many individuals, the development of diabetic peripheral neuropathy can therefore proceed completely unnoticed, making regular screening the most important tool for diagnosing the condition. Unfortunately, unlike nephropathy or retinopathy, diabetic peripheral neuropathy is not easily screened for, as the condition lacks reliable markers for early- or progressing disease. Therefore, screening for diabetic peripheral neuropathy currently revolves around diagnosing loss of protective sensation, judged by the inability to feel vibration or light touch. However, in their most recent guidelines, the American Diabetes Association has included screening for small fibre neuropathy using either the cold- and heat perception thresholds or pinprick as a clinical standard. Although this acknowledgement of the importance of assessing not only large- but also small nerve fibres is a huge step towards early detection of diabetic peripheral neuropathy, the overriding issue of insensitive, unreproducible, and inaccurate bedside tests for small nerve fibres remains. While cold- and heat perception and pinprick sensation are indeed mediated by small nerve fibres, the sensitivity of these methods, outside of extreme standardization only achievable in dedicated neuropathy research-centres, remain poor and not usable on an individual level. This lack of sensitivity has also become apparent in several large clinical trials, where the methods have continuously failed as robust clinical endpoints. Due to this, the hunt for a sensitive and reproducible method for adequate assessment of the small nerve fibres have begun. Amongst several interesting methods, two have gained particular interest (corneal confocal microscopy and skin biopsies with quantification of intra-epidermal nerve fiber density), due to their diverse strengths, although clinical application is currently limited to a few specialized sites. Furthermore, both methods suffer several inherent issues including that fact that they only provide information about the structure of the nerves and not the function. One method to assess the function of small cutaneous C-fibers is the assessment of the axon reflex flare response using laser doppler imaging (LDI) or Full-field laser perfusion imaging (FLPI), which has classically been studied using local heating. Unfortunately, this method is limited in clinical usage due to time-consumption. The investigators recently published an alternative method using a simple skin-prick application of histamine to evoke the response, which reduced the examination-time markedly. Before claiming the method to be a better alternative, the investigators do however need to prove that the method is as good as the original. In addition to the direct comparison of the histamine-induced and the heating-induced axon-reflex flare response the study will also assess spatial acuity in the same cohort as a secondary aim. Spatial acuity is considered as a measure of the sensory systems ability to code spatial information regarding an external stimulus. To investigate the spatial acuity, the 2-point discrimination task (2PDT) is often used. Spatial acuity has been shown to be impaired in several chronic pain condition. Additionally, it has been shown that the 2PDT may be a useful tool to understand the sensory changes in diabetes[8].

This trial is conducted in Europe. The purpose of this trial is to investigate if there is any change in the mechanism of energy expenditure (i.e. the way in which energy is used) in patients with type 1 diabetes, whilst taking two different, commercially available insulins for the treatment of their diabetes.

Continuous Correction

Type 1 Diabetes

The potential of currently available diabetes technologies could be further exploited. The investigators propose that sensor-augmented insulin pump therapy may be improved by continuous correction, i.e. continuous evaluation of the need for correction boluses. In practice, this is carried out by running the bolus calculator every 10 minutes. The glucose sensor will provide the bolus calculator with glucose input. Many times, the bolus calculator will come to the result that no insulin is needed. However, when the blood glucose is above the pre-set target value and a correction bolus is needed, an appropriate bolus is automatically delivered by the insulin pump. The investigators hypothesize that sensor-augmented continuous correction insulin pump therapy can reduce hyperglycemia without increasing the risk of hypoglycemia in patients with type 1 diabetes.

Type 1 Diabetes Mellitus

The study will consist of two study arms. Each arm will include a 24-96 hour outpatient run-in period prior to their exercise visit wearing the bi-hormonal bionic pancreas. In random order subjects will then complete two approximately 5-hour exercise visits, one wearing the bi-hormonal bionic pancreas and one wearing the insulin-only bionic pancreas.
