Project description:Despite the rapidly increasing prevalence of non-alcoholic fatty liver disease (NAFLD) in type 2 diabetes (T2D), few treatment modalities are currently available. We investigated the hepatic effects of the novel thiazolidinedione (TZDs), lobeglitazone (Duvie) in T2D patients with NAFLD. We recruited drug-naïve or metformin-treated T2D patients with NAFLD to conduct a multicenter, prospective, open-label, exploratory clinical trial. Transient liver elastography (Fibroscan®; Echosens, Paris, France) with controlled attenuation parameter (CAP) was used to non-invasively quantify hepatic fat contents. Fifty patients with CAP values above 250 dB/m were treated once daily with 0.5 mg lobeglitazone for 24 weeks. The primary endpoint was a decline in CAP values, and secondary endpoints included changes in components of glycemic, lipid, and liver profiles. Lobeglitazone-treated patients showed significantly decreased CAP values (313.4 dB/m at baseline vs. 297.8 dB/m at 24 weeks; P = 0.016), regardless of glycemic control. Lobeglitazone improved HbA(1C) values (7.41% [57.5 mM] vs. 6.56% [48.2 mM]; P < 0.001), as well as the lipid and liver profiles of the treated patients. Moreover, multivariable linear regression analysis showed that hepatic fat reduction by lobeglitazone was independently associated with baseline values of CAP, liver stiffness, and liver enzymes, and metformin use. Lobeglitazone treatment reduced intrahepatic fat content, as assessed by transient liver elastography, and improved glycemic, liver, and lipid profiles in T2D patients with NAFLD. Further randomized controlled trials using liver histology as an end point are necessary to evaluate the efficacy of lobeglitazone for NAFLD treatment.

Project description:IntroductionThe aim of this analysis was to evaluate the efficacy of lobeglitazone on albuminuria at 24 weeks of follow-up in patients with type 2 diabetes mellitus (T2DM) compared with pioglitazone using data from a randomized, double-blinded phase III trial.MethodsIn the phase III trial, patients who were inadequately controlled with metformin received 0.5 mg of lobeglitazone or 15 mg of pioglitazone for 24 weeks. Post hoc, exploratory analysis was used to investigate mean changes from baseline in the urine albumin-creatinine ratio (UACR) between the lobeglitazone (N?=?104) and pioglitazone (N?=?101) treatment groups.ResultsAfter 24 weeks of treatment, UACR was slightly decreased in the lobeglitazone group (- 4.3 mg/g creatinine [Cr]) compared to baseline and slightly increased in the pioglitazone group (5.2 mg/g Cr), with no change in the estimated glomerular filtration rate in either group; this difference was not statistically significant (P?=?0.476). The incidence of new-onset microalbuminuria (2.4%) and the progression of albuminuria by?>?1 stage (2.9%) in the lobeglitazone group were lower than the respective values in the pioglitazone group (6.8 and 6.1%, respectively). Of the patients in the lobeglitazone group, 50% exhibited regression to normoalbuminuria, compared to 39.3% of the patients in the pioglitazone. In subjects in the lobeglitazone group with micro- and macroalbuminuria, UACR tended to be more decreased and HbA1c was more reduced compared to those with normoalbuminuria (P?=?0.014).ConclusionLobeglitazone had a tendency to improve albuminuria in patients with T2DM and had comparable effects on albuminuria as pioglitazone which has demonstrated beneficial effects.Trial registrationClinicalTrials.gov identifier, NCT01106131.

Project description:Type 2 Diabetes Mellitus (T2DM) is a chronic disease which corresponds to 90% of the worldwide cases of diabetes, mainly due to epigenetic factors such as unhealthy lifestyles. First line therapeutic approaches are based on lifestyle changes, most of the time complemented with medication mostly associated with several side effects and high costs. As a result, the scientific community is constantly working for the discovery and development of natural therapeutic strategies that provide lower financial impact and minimize side effects. This review focus on these nature-based therapeutic strategies for prevention and control of T2DM, with a special emphasis on natural compounds that present pharmacological activity as dipeptidyl peptidase-4 (DPP4), alpha-amylase, alpha-glucosidase, lipase, and protein tyrosine phosphatase 1B (PTP1B) inhibitors.

Project description:Background: The purpose of this article is to clarify and define medical qigong and to identify an appropriate study design and methodology for a large-scale study looking at the effects of qigong in patients with type 2 diabetes mellitus (T2DM), specifically subject enrollment criteria, selection of the control group and study duration. Methods: A comprehensive literature review of English databases was used to locate articles from 1980-May 2017 involving qigong and T2DM. Control groups, subject criteria and the results of major diabetic markers were reviewed and compared within each study. Definitions of qigong and its differentiation from physical exercise were also considered. Results: After a thorough review, it was found that qigong shows positive effects on T2DM; however, there were inconsistencies in control groups, research subjects and diabetic markers analyzed. It was also discovered that there is a large variation in styles and definitions of qigong. Conclusions: Qigong exercise has shown promising results in clinical experience and in randomized, controlled pilot studies for affecting aspects of T2DM including blood glucose, triglycerides, total cholesterol, weight, BMI and insulin resistance. Due to the inconsistencies in study design and methods and the lack of large-scale studies, further well-designed randomized control trials (RCT) are needed to evaluate the 'vital energy' or qi aspect of internal medical qigong in people who have been diagnosed with T2DM.

Project description:Peroxisome proliferator-activated receptor ? (PPAR?) has received significant attention as a key regulator of glucose and lipid homeostasis. In this study, we synthesized and tested a library of novel 5-benzylidene-thiazolidin-2,4-dione (BTZD) derivatives bearing a substituent on nitrogen of TZD nucleus (compounds 1a-1k, 2i-10i, 3a, 6a, and 8a-10a). Three compounds (1a, 1i, and 3a) exhibited selectivity towards PPAR? and were found to be weak to moderate partial agonists. Surface Plasmon Resonance (SPR) results demonstrated binding affinity of 1a, 1i and 3a towards PPAR?. Furthermore, docking experiments revealed that BTZDs interact with PPAR? through a distinct binding mode, forming primarily hydrophobic contacts with the ligand-binding pocket (LBD) without direct H-bonding interactions to key residues in H12 that are characteristic of full agonists. In addition, 1a, 1i and 3a significantly improved hyperglycemia and hyperlipidaemia in streptozotocin-nicotinamide (STZ-NA)-induced diabetic rats at a dose of 36?mg/kg/day administered orally for 15 days. Histopathological investigations revealed that microscopic architecture of pancreatic and hepatic cells improved in BTZDs-treated diabetic rats. These findings suggested that 1a, 1i and 3a are very promising pharmacological agents by selectively targeting PPAR? for further development in the clinical treatment of type 2 diabetes mellitus.

Project description:Advances in genotype technology in the last decade have put the pharmacogenomics revolution at the forefront of future medicine in clinical practice. Discovery of novel gene variations in drug transporters, drug targets, effector proteins and metabolizing enzymes in the form of single-nucleotide polymorphisms (SNPs) continue to provide insight into the biological phenomena that govern drug efficacy and toxicity. To date, novel gene discoveries extracted from genome-wide association scans and candidate gene studies in at least four antidiabetic drug classes have helped illuminate possible causes of interindividual variability in response. Inadequate protocol guidelines for pharmacogenomics studies often leads to poorly designed studies, making it hard to formulate a definitive conclusion regarding the clinical relevance of the information at hand. These issues, along with the ethical, social, political, legislative, technological, and economic challenges associated with pharmacogenomics have only delayed its entry to mainstream clinical practice. On the other hand, these issues are being actively pursued and rapid progress is being made in each area which assures the possibility of gaining widespread acceptance in clinical practice.

Project description:Although both sodium glucose co-transporter 2 inhibition by dapagliflozin and thiazolidinedione, pioglitazone have glucose-lowering and anti-inflammatory effects, the therapeutic efficacy of their combination on diabetic nephropathy has not been investigated. 9-week-old male db/db mice were randomly assigned to 4 groups and administrated with (1) vehicle, (2) dapagliflozin, (3) pioglitazone, or (4) dapagliflozin and pioglitazone combination. Human proximal tubule (HK-2) cells were treated with glucose or palmitate acid in the presence of medium, dapagliflozin, pioglitazone, or both. Glomerular tuft area and mesangial expansion of the kidney more reduced in the combination group compared to control and single therapy groups. Podocyte foot process width and glomerular basement membrane thickness decreased regardless of treatment, while the combination group showed the slowest renal hypertrophy progression (P < 0.05). The combination treatment decreased MCP-1, type I and IV collagen expression in the renal cortex. Only the combination treatment decreased the expression of angiotensinogen, IL-6, and TGF-? while it enhanced HK-2 cell survival (all P < 0.05). In conclusion, dapagliflozin and pioglitazone preserved renal function, and combination therapy showed the greatest benefit. These findings suggest that the combination therapy of dapagliflozin with pioglitazone is more effective than the single therapy for preventing the progression of nephropathy in patients with type 2 diabetes.

Project description:Diabetes Mellitus continues to be a major non- communicable disease with global burden of 366 million at present and projected to increase to 439 to 552 million by 2030, India being the hub of diabetes. Sodium glucose transporter 2 (SGLT2) inhibitors presents a new class of anti-diabetic drugs having an insulin-independent mechanism that offers a considerable advantage of increasing urinary glucose excretion without inducing hypoglycemia and promoting weight loss due to loss of 300 to 400kcal/day, Canagliflozin being the 1(st) successful candidate of this group and became the first SGLT2 inhibitor to be FDA approved on March 29, 2013. In various clinical trials, it has shown promising results in controlling glycemia, causing weight loss, reducing systolic and diastolic BP and cardiovascular risk. There are some safety concerns associated with its use e.g. genital mycotic infections, increased urination, urinary tract infection and hyperkalemia, which need to be carefully addressed while using this drug.

Project description:In this project, using discovery-based mass spectrometry approach and adopting data-dependent LC-MS/MS, we detected and identified modified peptides in complex clinical plasma samples and developed first-level biomarker verification strategy. Further, using liquid chromatography-multiple reaction monitoring mass spectrometry (LC-MRM-MS) based targeted approach which virtually quantifies irreversible oxidation at any targeted cysteine, we quantified cysteine tri-oxidation in HSA in diabetes patients. Site-specific tri-oxidized HSA could be a potential biomarker of diabetes and provide directive of disease mechanism.

Project description:BACKGROUND:Chronic inflammation is important in the development of benign prostatic hyperplasia (BPH) and certain oral antidiabetic medications have anti-inflammatory properties. The purpose of this study was to determine if use of thiazolidinediones or metformin was associated with a reduced risk of requiring medical or surgical treatment for BPH compared to sulfonylureas among diabetic men. METHODS:We constructed a retrospective cohort of 192,457 male veterans newly prescribed either rosiglitazone, pioglitazone, metformin, or a sulfonylurea. We used Cox proportional hazard regression to assess the association between thiazolidinedione or metformin use and the risk of requiring medical or surgical treatment for BPH compared to sulfonylurea use. New BPH treatment was defined by either a new prescription for a ?-1 blocker or 5?-reductase inhibitors or a surgical procedure indicated for severe BPH. RESULTS:In 259,995 person-years of follow up we identified 14,690 new treatments for BPH. After adjusting for covariates including age, HbA1c, and body mass index, we found no association between rosiglitazone (adjusted hazard ratio [aHR] 1.02, 95% CI 0.86, 1.20), pioglitazone (aHR 0.79, 95% CI 0.45, 1.38), or metformin use (aHR 0.99, 95% CI 0.94, 1.03) and risk of new medical or surgical treatment for BPH compared to sulfonylureas. Analyses ignoring prescriptions for non-selective ?-1 blockers (terazosin, doxazosin, prazosin) from our BPH case definition (n = 11,079), yielded similar results. CONCLUSIONS:In this large cohort, we observed no association between the use of thiazolidinediones or metformin and new medical or surgical treatment for BPH compared to sulfonylureas.
