Filter by:This study aims to determine whether Lactiplantibacillus plantarum 299v (Lp299v) supplementation will reduce systemic inflammation and prolong residual beta cell function in individuals newly diagnosed with Type 1 diabetes. The investigators hypothesize that probiotic-induced alterations in the intestinal microbiota may favorably alter the post-onset disease state.
The purpose of this research study is to find out how bones are affected in children and adolescents with type 1 diabetes (T1D) as compared to children and adolescents without type 1 diabetes.
The scientific goal of this study is to examine the effects of a ketogenic diet on hypoglycemia tolerance and brain function in people with type 1 diabetes mellitus (T1D) and to clarify the mechanistic role of ketones in this process. Glycemic management of T1D is typified by alternating periods of hyper- and hypo-glycemia. Because brain metabolism under usual conditions depends on glucose, acute hypoglycemia leads to immediate complications including impaired cognitive function and a counter-regulatory hormone response. Recurrent hypoglycemia is associated with functional and structural changes in the brain and contributes to the cognitive decline observed in individuals with diabetes. The state of nutritional ketosis (as it occurs during fasting or when following a ketogenic [very low carbohydrate] diet) may protect against these acute and chronic complications. As the body relies on fat metabolism, ketone bodies build up and provide an alternative fuel for the brain. Studies during hypoglycemia have shown better cognitive function and less hypoglycemia symptoms in the setting of nutritional ketosis or with ketone administration. This physiological benefit may have special relevance for people with T1D who experience hypoglycemia frequently. To date, no mechanistic studies have examined brain effects of nutritional ketosis in T1D; nor have any trials explored the potential relevance of this for diabetes care.
Despite major technological advances, management of type one diabetes mellitus (T1D) remains suboptimal, putting millions of people at risk for immediate and long-term complications. After meals, a mismatch between carbohydrate absorption rate and insulin action typically leads to alternating periods of hyper- and hypoglycemia. A conceptually promising approach to control both problems is dietary carbohydrate restriction to reduce postprandial blood glucose changes and insulin needs. In a prior survey study, the investigators documented exceptional glycemic control (HbA1c 5.67%) and low acute complication rates among 316 children and adults with T1D consuming a very-low-carbohydrate (VLC) diet. Despite these promising preliminary results, the use of VLC diets for T1D remain controversial, because of their restrictive nature and theoretical concerns regarding growth, ketoacidosis and hypoglycemia risks and efficiency of glucagon treatment for hypoglycemia. Glucagon is used as a rescue medication during severe hypoglycemia and increases blood glucose levels by mobilizing liver glycogen stores. If these stores are depleted during carbohydrate restriction, glucagon response may be inadequate and put individuals at risk for refractory hypoglycemia. A physiologic study has shown a blunted but still adequate response to glucagon in n=10 participants after following a VLCD for 1 week. Longer-term studies have not been done. To test the hypotheses that glucagon response remains adequate while following a VLC diet in the longer term, the investigators will conduct a glucagon challenge in participants who are assigned to the VLC arm of a randomized-controlled feeding study in 32 young adults with T1D who will receive a VLC vs a standard diet for 12 weeks. After an overnight fast, twelve participants in the VLC arm will receive IV insulin to lower blood glucose levels to 60 mg/dL, followed by a glucagon injection and monitoring of blood glucose levels and other metabolic fuels.
This is a study of the Minimed 670G 4.0 insulin pump, assessing the efficacy of the Advanced Hybrid Closed Loop (AHCL) algorithm in controlling blood glucose levels in Type 1 Diabetes.

Type 1 diabetes requires a high level of involvement of patients to obtain good control by following complex therapeutic recommendations. Motivational Interviewing has proven to be effective in changing behaviors in sedentary people, with addictions and with obesity. Our objective is to evaluate the impact of an intervention with Motivational Interviewing in patients with type 1 diabetes, through a randomized controlled clinical trial. At least sixty patients with type 1 diabetes will be included with HbA1c> 8% that will be randomized with a ratio of 1: 1. In the intervention group, Motivational Interviewing will be applied in the routine clinical appointments with the Endocrinologist, while the control group will receive the same visits but in a traditional way. The primary result will be self-care behaviors according to a validated questionnaire. Secondary outcomes include: HbA1c, number of hypoglycemia, motivation with self-care, self-efficacy, quality of life, compliance with patients' own objectives, lipid profile, weight and blood pressure. The professionals will be trained in Motivational Interviewing with the objective of favoring the adherence to self-care, the motivation of the patient and improving doctor-patient relationship. They will also be evaluated through a specific questionnaire.
It is thought that altered brain lactate handling is involved in the development of impaired awareness of hypoglycemia (IAH), i.e. the inability to timely detect hypoglycemia in people with type 1 diabetes (T1DM). Infusion of lactate diminishes symptomatic and hormonal responses to hypoglycemia in patients with normal awareness of hypoglycemia (NAH), resembling the situation of patients with IAH. It is unknown whether this attenuating effect is due to brain lactate oxidation or the result of lactate-induced alterations of global and regional cerebral blood flow (CBF). Normally, hypoglycemia causes a redistribution of CBF towards the thalamus, from where the sympathetic response to hypoglycemia is coordinated, but in IAH this effect is absent and global CBF is increased. We hypothesize that lactate infusion in patients with NAH will result in blunting of thalamic activation and/or enhanced global CBF. If so, these results may help delineating the pathogenesis of IAH which eventually creates new avenues to protect against the morbidity associated with hypoglycemia and IAH. Study design: Single-blind placebo controlled, randomized cross-over intervention study Study population: T1DM patients with NAH (n=10) Intervention: On two separate occasions, patients with T1DM and NAH will undergo a hyperinsulinemic euglycemic-hypoglycemic glucose clamp with or without the infusion of exogenous lactate. ASL-MRI will be applied to measure global and regional changes in CBF. Main study parameters/endpoints: The change in regional thalamic CBF in response to intravenous lactate infusion compared to placebo, during hypoglycemia
