Active clinical trials for "Glucose Intolerance"

People with type 2 diabetes are at risk of complications linked with high blood sugars and these are monitored for in healthcare appointments. However, people with type 2 diabetes commonly suffer with additional health conditions that can affect the liver, heart and their breathing while sleeping. These conditions are thought to be caused by a similar underlying process that causes type 2 diabetes, as a result they are very common in people type 2 diabetes. Despite this they are not part of the routine health check for these people. Worryingly, current research suggests that the risk for developing these health problems, and direct complications of type 2 diabetes, can start at blood sugar levels below the threshold of type 2 diabetes. In a group of people said to have prediabetes. These people do not currently undergo annual healthcare appointments to monitor for these health complications or other linked health conditions. This study aims to pilot a new style of clinic to address these issues. The investigators will perform a multi-morbidity assessment, where they will look for several different health problems at the same time. The investigators will be looking at health problems linked with high blood sugars, this will include problems with the liver, heart, nerves, eyes, and participants breathing overnight. They have developed a clinic visit which uses questionnaires, simple examination techniques and modern devices to try and identify these health problems. An important part of healthcare is the burden it places on people with health problems, with this in mind the investigators will be giving the people involved in their study a voice to try and direct future research and healthcare, the investigators will ask them to provide feedback on their experience in taking part in the study and what their thoughts are in undergoing a longer but more comprehensive health appointment.

This 16-week study will use an experimental approach called the Sequential Multiple Assignment Randomized Trial to help determine which combination and sequence of weight loss program features are most effective in people who are at risk for type 2 diabetes. Participants in the study will be initially randomized to consume either a high or reduced carbohydrate diet. After 4 weeks, participants will be identified as Responders (greater than or equal to 2.5% weight loss) or Non-Responders (less than 2.5% weight loss). Responders will continue with their initial randomized group for the remainder of the trial. Non-responders will be re-randomized to 2nd stage interventions of either including additional exercise counseling and training or beginning a time restricted eating protocol for the remainder of the trial.

The goal of this study is to address the risk of diabetes among men by creating a Diabetes Prevention Program (DPP) tailored to men.

Dorzagliatin, a novel dual allosteric activator of glucokinase. reduces blood glucose by increasing insulin secretion by enhancing sensitivity of beta cells to glucose. In this placebo controlled cross over study, we examined the effects of dorzagliatin in people with impaired glucose tolerance and normal glucose tolerance.

Sleep disordered breathing is associated with impaired glucose tolerance and incident diabetes. Nocturnal hypoxemia is a potential stimulus of glucose intolerance. It is especially severe and highly prevalent in high altitude residents. Intervening on nocturnal hypoxemia may therefore improve glucose control and decrease the public health burden in high altitude populations. The objective of this study is to examine the impact of hypoxemia on glucose homeostasis in high altitude residents. The investigators will address this objective by examining the effect of supplemental oxygen on glucose in a randomized cross-over study.

Prediabetes is a common condition in overweight individuals affecting approximately 35% of American adults and 30% of Australian adults. Like diabetes, prediabetes is a serious risk factor for cardiovascular disease, eye, kidney and liver disease, and some types of cancer. Appropriate blood glucose control is crucial in preventing pre-diabetes complications and onset of diabetes, yet clinical practice, backed by randomised trials, reports that many patients treated with standard dietary guidelines or with the first-line treatment of diabetes patients, metformin, do not improve blood glucose control sufficiently. The overarching goal of the present project is to improve the efficacy of metformin mono-therapy in pre-diabetes and early type 2 diabetes.

This is a multicenter open-label, pilot study to evaluate the safety and tolerability of bromocriptine, a dopamine D2/D3 receptor and serotonin 5-HT2C receptor agonist, as an adjunct to preexisting standard-of-care antipsychotic drug (APD) regimens in the management of APD-associated impaired glucose tolerance (IGT)/insulin resistance (IR). The ultimate aim of the study team is to evaluate the efficacy of bromocriptine in treating the metabolic disturbances associated with APDs and the hypothesis is that bromocriptine will be a well-tolerated, safe, and inexpensive way to ameliorate these metabolic complications and prevent or delay the onset of type 2 diabetes (T2D). This study will be a small, short-duration pilot focusing on safety and tolerability. Twenty psychiatrically stable APD-treated outpatients, at two sites (VA Pittsburgh and Stanford), aged 18 to 60 years old, with schizophrenia and comorbid IGT will be recruited and receive 6 weeks of bromocriptine (flexibly titrated, 2.5-5.0 mg PO daily). Key inclusion criteria are: 1) currently being treated with second generation APDs for 3 or more months with no change in dose in the 1 month prior to enrollment, 2) fasting glucose 100 to 125mg/dL and/or hemoglobin A1c (HbA1c) 5.7-6.4%. Key exclusions are: 1) prior APD nonadherence, 2) drug/alcohol abuse in the 3 months prior to screening, 3) a history of violent behavior/psychoses, 4) pregnancy, or 5) a diagnosis of diabetes. Subjects on other dopamine agonists or on medications that may interact with bromocriptine and those taking corticosteroids or other medications that may alter glucose levels will be excluded. The purposes of the study are to demonstrate safety/tolerability, demonstrate feasibility, provide proof of concept, and provide an open-label assessment of the metabolic and psychiatric effects of bromocriptine in patients with schizophrenia treated with APDs. The primary metabolic outcome measures will be change in IR as measured by the HOMA-IR and change in IGT measured by HbA1c. Secondary metabolic outcome measures include body weight, fasting lipids, and prolactin. The specific aims are as follows: Specific aim 1: To establish the safety and tolerability of bromocriptine in patients with schizophrenia and IGT/IR treated with APDs. Specific aim 2: To demonstrate feasibility/proof of concept for an improvement in APD-induced IGT/IR with bromocriptine.

To test these hypotheses, The Investigators will recruit 100 overweight and obese adolescents with HbA1c ranging across the ADA classification spectrum from normal to prediabetes,(nearly 40:normoglycemi, 30: IFG, 30:1GT) measure free-living glucose by continuous glucose monitoring (CGM), and assess the relationships among CGM outcomes, HbA1c, and OGTT results (FPG and 2-h glucose). Individual with overt diabetes will be excluded. This will be a 2 visit study. Subjects will be coming to Fortis CDOC after a minimum 8-hour overnight fast. Informed written consent and validated questionnaire in a language known to them (English/Hindi) will be obtained from all participants. Clinical details will be obtained from the case records of the patients. Note of visible markers of insulin resistance (acanthosis nigricans, buffalo hump, double chin, subcutaneous fat pads, skin) Anthropometry, skinfolds & blood pressure will be recorded. Overweight and, obesity will be defined according to predefined guidelines for Asian Indian. Abdominal obesity is defined as waist circumference of ≥ 90 centimetres (cms) in males and ≥ 80 cms in females. A blinded iPro Continuous Glucose Monitor (Medtronic MiniMed, Inc) will be inserted. After a calibration period of 1 hour, fasting laboratory result will be collected: FPG, HbA1c. HbA1c will be done by HPLC (NGSP approved, turbid inhibition immunoassay). Then subjects will consume 1.75 g/kg glucose, maximum 75 g (glucose beverage) and will have a second venepuncture 2 hours later for plasma glucose measurement. While awaiting the 2-hour venepuncture, participants will be provided instructions on CGM device care and calibration. Participants will be instructed to wear the CGM device for a minimum of 72 hours and to not change any of their current dietary or activity habits for the period of CGM wear. They will be trained to use a glucose monitor and collect capillary blood glucose values at least three times daily, prior to meals. Participants will also be asked to complete a simple log of their activity, as well as record dietary intake, and sleep and wake times. The iPro and log-sheet will be returned in person after a minimum of 72 hours of recording time. Investigators and patients will be kept blinded to CGM recordings throughout the study. Daily glycaemic variability will be assessed by the change in the mean amplitude of glucose excursions (MAGE) index, and through the standard deviation (SD) of the mean 24-hour blood glucose concentration. Day-to-day variability will be assessed through the mean of daily differences (MoDD in mg/dL). Daily glycaemic control will be assessed by the mean (M) daily CGM value, as well as by the times (in minutes/day) spent in optimal glycaemic range (70-140 mg/dL) and above predefined hyperglycaemic thresholds (140 ,180 and 200 mg/dL) together with the corresponding area under the curve (AUC) values. In addition, areas under 24-hour glycaemic traces (AUCs) will be analysed to estimate: overall hyperglycaemia (defined asAUC≥100 mg/dL over the full 24-hour period = AUCtotal);postprandial hyperglycaemia (AUC[0-4 h], i.e. for four-hour periods after each of the main meals and, if considered relevant by the core laboratory, after additional snacks = AUCpp); and basal hyperglycaemia, i.e. overall hyperglycaemia - postprandial hyperglycaemia (AUCb)

This study is a prospective, randomized, open-label, multi-center trial. The primary objective of the study is to assess whether XZK 1200mg/d, compared to atorvastatin 20mg/d, has a favorable impact on HbA1c levels at 24 weeks of treatment in dyslipidemia patients with prediabetes

The study aims to evaluate the acceptability, feasibility, and preliminary efficacy of a digital lifestyle intervention, called Fitness Digital (FitD), for individuals with prediabetes or type 2 diabetes.
