Active clinical trials for "Insulin Resistance"

Patatin-like phospholipase domain-containing protein-3 (PNPLA3), the transmembrane 6 superfamily member 2 protein (TM6SF2) and membrane bound O-acyltransferase domain containing 7 (MBOAT7) genes are involved in non-alcoholic fatty liver disease (NAFLD) development and worsening. Following the actual scientific knowledge, some studies have identified the genetic background surrounding NAFLD, counting up to forty different genetic variants that seem to exert also a crucial role in the disease evolution, according to the natural history, until hepatocellular carcinoma onset. However, few data exist regarding their influence on the treatment response. The aim was to explore the effect of 303 mg of silybin-phospholipids complex, 10 mg of vitamin-D and 15 mg of vitamin-E twice a day for six months in NAFLD patients carrying PNPLA3-rs738409, TM6SF2-rs58542926 and MBOAT7-rs641738 genetic variants. The assessed mutations are independently associated with no response to a silybin/vitamin D-based therapy and could be useful therapeutic predictive markers in this context.

The objective of this study is to evaluate the safety and feasibility of a smart bolus calculator that adjusts insulin dosing for meals according to real-time insulin sensitivity (SI) in adolescents with type 1 diabetes (T1D) using a hybrid closed loop (HCL) system during an active week of diabetes camp.

In addition to its effect on maintaining calcium homeostasis and mineralization of bone, vitamin D has been linked to play a pivotal role in different medical conditions including type 2 diabetes mellitus. Vitamin D plays a major role in both insulin secretion and decreasing the insulin resistance hence has a major impact on glucose tolerance. This study is designed to determine the non-skeletal effects of vitamin D in improving the glucose tolerance in type 2 diabetic patients by decreasing the insulin resistance

The purpose of this study is to find out if tadalafil can help overweight and obese people metabolize blood sugar more efficiently. The investigators also want to find out if 20 mg/day of tadalafil for 3 months is safe to take without causing too many side effects. The investigators are plan to enroll 100 subjects at Massachusetts General Hospital (MGH).

Adipocyte fatty acid binding protein (A-FABP) is a member of the FABP super family, is abundant in adipocytes and macrophages. Regulatory functions of A-FABP in lipid and glucose metabolism have been described, and it is suggested to play an important role in the pathogenesis of metabolic syndrome.We hypothesize that obstructive sleep apnea (OSA) may upregulate A-FABP production and thus causally contribute to metabolic dysfunction. Our group has recently demonstrated that A-FABP, expressed and secreted from adipocytes, is present in the blood stream .The levels of A-FABP correlated with various metabolic variates in the metabolic syndrome. Furthermore, we have obtained novel data in men with a range of sleep disordered breathing showed that the duration of oxygen desaturation correlated with circulating levels of A-FABP, independent of age and waist/body mass index. The current proposal aims to pursue this finding and further explore the role of A-FABP in the association of OSA and metabolic dysfunction.

The purpose of this study is to determine whether hydroxychloroquine (HCQ) reduces insulin resistance in non-diabetic subjects with rheumatoid arthritis (RA). The investigators will conduct a double-blind randomized crossover trial in subjects with RA to test the hypothesis that HCQ improves insulin sensitivity. The investigators will also use data from the trial to identify determinants of insulin resistance in RA. The investigators hypothesize that RA will be associated with an increased risk of insulin resistance and that independent risk factors for increased insulin resistance in RA include higher BMI, elevated acute phase reactants, greater fat to muscle ratio, and less physical activity.

The importance of vitamin D (VitD) in the prevention and treatment of human health conditions has gained increased attention in recent years. As a result, medical providers of all categories are screening clinical VitD status frequently, yet become challenged with how to best advise patients regarding repletion of VitD status, i.e. which form of VitD replacement is most effective. It has been recognized that to achieve significant effects - serum concentrations >30ng/ml (75 nmol/ml) - it is necessary, as well as safe, to recommend substantially higher doses than were previously thought sufficient. These higher doses can be easily achieved orally. This clinical trial aims to compare absorption of three available forms of this fat-soluble vitamin, due to the potential differences in absorption of different preparations. High-quality powdered, chewable and lipid-emulsified VitD are readily available as supplements, yet these have not been systematically compared. This three-arm, randomized clinical trial will compare the difference in serum 25-hydroxycholecalciferol (25-OH)D concentration between the three arms at baseline and after random administration of one of the three VitD preparations for 12-weeks at a dosage of 10,000 IU VitD per day. The investigators hypothesize that the three forms of vitD will result in an equivalent increase in serum 25OHD.

The investigators here propose to perform a prospective randomized intervention trial in post-menopausal women to investigate the endocrine network, which contributes to the changes in skeletal muscle mass during weight loss.

The purpose of this study is to evaluate the efficacy of Traditional Chinese Treatment(TCT) on insulin sensitivity and other related factors in type 2 diabetes by using an double-blind, randomized, parallel control and prospective study This traditional compound Chinese herb preparation is referred to this study, with three kinds of plants: 50 mg of Coptis Chinensis, 30 mg of Astragalus mambranesceus and 120 mg of Lonicera Japonica, all of which are selected by The Chinese Academy of Medical Sciences among those traditionally considered effective and safe in the treatment of diabetes. Patients enrolled were randomized into TCT group and placebo group administrated with TCT and placebo respectively. Glucose disposal rate (GDR), fasting plasma glucose (FPG), postprandial plasma glucose (PPG), HbA1C and other metabolic components were assessed at baseline and end point

Gestational diabetes (GDM) is a condition that manifests as high blood sugar levels (hyperglycemia) during pregnancy in previously healthy women. It develops as a result of increased maternal body's resistance to insulin - a major hormone that allows for utilisation of glucose (sugar taken in with food) within cells. It was found out that GDM occurs more frequently in overweight women but also in women with a history of certain conditions such as polycystic ovary syndrome (PCOS). Usually, GDM disappears after pregnancy is completed but it is associated with some serious hazards for women and her unborn child, if untreated properly. Diet is a first-choice treatment but sometimes insulin therapy must be initiated if keeping a diet alone is not enough to maintain blood sugar within recommended values. Insulin therapy is effective but it requires several injections during each day and insulin is a strong acting hypoglycemic agent that may induce rapid falls in blood sugar, also dangerous for mother and unborn child. In the investigators study, the investigators would like to investigate if metformin that is a commonly used hypoglycemic drug can be effectively used for GDM treatment. Metformin has been used successfully for a long time to treat type 2 diabetes mellitus and PCOS and, according to current data, it is not dangerous neither for mother nor for baby when used during gestation.
