InflammationFibrosis1 moreNo proven treatment exists for nonalcoholic fatty liver disease (NAFLD) in children and adolescents. We aim to determine the efficacy of lifestyle intervention with or without antioxidant therapy in pediatric NAFLD.
Co-treatment With Pegvisomant and a Somatostatin Analogue (SA) in SA-responsive Acromegalic Patients...
AcromegalyInsulin Resistance1 moreThe purpose of this study is to investigate if co-treatment of acromegalic patients, who beforehand are considered well-controlled on SA monotherapy, with pegvisomant and SA will improve insulin sensitivity and glucose tolerance, and if these effects of co-treatment can be obtained at a neutral cost as compared to SA mono therapy. Second to investigate body composition, substrate metabolism, symptoms, intrahepatic and intramyocellular fat.
Vitamin D, Insulin Resistance, and Cardiovascular Disease
Vitamin D DeficiencyInsulin Resistance3 moreIn recent years, vitamin D has been shown not only to be important for bone and calcium metabolism but also for homeostasis of critical tissues involved in vascular disease in patients with diabetes. Epidemiological studies indicated the high prevalence of vitamin D deficiency among Type 2 DM patients and suggest an increased risk of cardiovascular disease and hypertension with low vitamin D levels. The objective of this proposal is to evaluate the effects of vitamin D replacement on blood pressure control and vascular disease in vitamin D deficient hypertensive patients with diabetes
Combination Metformin and Oral Contraception for Polycystic Ovary Syndrome (PCOS)
Polycystic Ovary SyndromePCOS1 moreThe purpose of this research study is to determine if adding Metformin, a drug that reduces insulin resistance, to birth control pills will reduce the risk of developing type 2 diabetes, high blood pressure. high lipid levels and heart disease in women with PCOS
Adiponectin and Insulin Resistance in Diabetic Nephropathy
Diabetic NephropathyPlasma adiponectin concentration is inversely associated with renal function. There is little literature on adiponectin levels and regulation by antihypertensive medication with an angiotensin II-receptor blocker (ARB), especially in subjects with type 2 diabetes in different stage of chronic kidney disease (CKD).

Effects of (1,3), (1,6)-Beta-D-glucan on Insulin Sensitivity and Inflammatory Markers of the Metabolic...
OverweightInsoluble (1,3),(1,6)-beta-D-glucan from bakers yeast are indigestible polysaccharides. Previous studies indicate that the intake of insoluble dietary fiber is strongly associated with reduced risk of type 2 diabetes and cardiovascular disease. However, the mechanisms leading to this phenomenon are largely unknown. There are close relations between metabolic and inflammatory pathways, and a number of hormones, cytokines, signal proteins, bioactive lipids, and transcription factors have been shown to be involved in both systems. Beta-D-glucans have been suggested to play a role as so called biological response modifiers. Studies in animals indicate that even small doses of (1,3),(1,6)-beta-D-glucan may have beneficial effects on immune activity, i.e., by reducing the secretion of inflammatory factors. The investigators hypothesize that the intake of isolated (1,3), (1,6)-beta-D-glucan from bakers yeast improves inflammatory makers and insulin-sensitivity in overweight subjects with increased C-reactive protein concentrations at baseline.

Comparison of Oxidative Stress and Insulin Resistance Before and After Using Physioneal in Peritoneal...
Kidney Failure,ChronicPatients affected by end-stage renal disease (ESRD) are subjected to enhanced oxidative stress, as a result of reduced anti-oxidant systems and increased pro-oxidant activity. Besides, insulin resistance is also very common in ESRD patients. Both enhanced oxidative stress and insulin resistance increase the risk of atherosclerosis and cardiovascular mortality, and intention to reduce oxidative stress and insulin resistance is important in ESRD patients who suffer from high cardiovascular risk. The high concentration of glucose and glucose degradation products (GDP), high lactate, and low pH in conventional peritoneal dialysis (PD) solutions are known as bioincompatible factors, which are believed to increase oxidative stress in PD patients. Physioneal®, a more biocompatible dialysis solution with neutral pH, physiologic bicarbonate concentration and low GDP level, has been applied in Europe for several years. Previous studies of Physioneal® have revealed advantages of improved infusion pain, more efficient acid-base control, increased ultrafiltration, and reduced peritonitis duration. However, its effects on oxidative stress and insulin resistance in peritoneal dialysis patients are not reported yet. The comparison of oxidative stress and insulin resistance before and after using Physioneal® may help to elucidate the possibly beneficial effects on uremic patients, which frequently suffer from increased oxidative stress and insulin resistance. Thirty continuous ambulatory peritoneal dialysis (CAPD) patients will be selected in this study, and receive conventional solution (Dianeal® PD-2 or PD-4) for a baseline period of 3 months. Then Physioneal® will be used for 3 months. Clinical conditions, biochemical and hematological parameters, oxidative markers in blood and effluent, and insulin resistance will be measured at baseline, before and after Physioneal®, and some markers will be measured 1 month after discontinuing Physioneal® and changing back to conventional solution. The medication used in each patient will be recorded, and the dialysis prescription will be adjusted by a nephrologist according to clinical data. The data collected before and after Physioneal® will be analyzed by paired-t test.
