BACKGROUND: sarcopenia contributes to the development of frailty syndrome. Frailty syndrome is potentially improved by modifying insulin resistance, inflammation, and myostatin level. This study is aimed to investigate the effect of metformin on handgrip strength, gait speed, myostatin serum level, and health-related quality of life (HR-QoL) among non-diabetic pre-frail elderly patients. METHODS: a double blind randomized controlled trial study was conducted on non-diabetic elderly outpatients aged ≥ 60 years with pre-frail status based on phenotype and/ or index criteria (Cardiovascular Health Study and/ or Frailty Index 40 items) consecutively recruited from March 2015 to June 2016 at Cipto Mangunkusumo Hospital...

BACKGROUND: Neutrophil gelatinase-associated lipocalin (NGAL), an acute phase protein released by neutrophils, has been described as biomarker of inflammatory states. Type 2 diabetes mellitus (T2DM) is characterized by increased inflammation and an elevated risk for embolization of carotid artery stenosis (CAS). We aimed to explore the role of NGAL systemically and in plaques of diabetics undergoing carotid endarterectomy. Moreover, the potential anti-inflammatory effect of metformin on NGAL was addressed in diabetics...

Most patients with type 2 diabetes have excess adiposity. There is wide consensus that adequate treatment of type 2 diabetes requires a simultaneous approach to overweight/obesity and the remaining cardiovascular risk factors. Non-pharmacological interventions (diet, exercise) represent the cornerstone of the treatment of patients with type 2 diabetes. Weight loss through lifestyle modification has shown clear benefits in these patients, requiring an individualised and multidisciplinary approach with structured programmes endowed with specific resources...

Diabetes mellitus is a growing in exponential proportions. If the current growth trend continues, it may result in every third adult in the United States having diabetes mellitus by 2050, and every 10(th) adult worldwide. Type 2 diabetes mellitus (T2DM) confers a 2- to 3-fold increased risk of cardiovascular (CV) events compared with non-diabetic patients, and CV mortality is responsible for around 80% mortality in this population. Patients with T2DM can have other features of insulin resistance-metabolic syndrome like hypertension, lipid abnormalities, and obesity which are all associated with increased CV disease and stroke risk even in the absence of T2DM...

BACKGROUND: Diabetes mellitus type 2 (T2DM) often co-exists with hypertension, and this aggregation of co-morbidities amplifies the risk for future cardiovascular events. Therefore, it appears crucial to understand the essence of choosing oral and non-insulin injectable anti-diabetic drugs (ADs) with a favorable hemodynamic impact that could partially attenuate the increased baseline cardiovascular risk. OBJECTIVE: We sought to evaluate the effect of ADs on blood pressure (BP) indices and to assess the potential role of certain ADs towards hypertension treatment...

Among randomized controlled trials (RCTs), trials for primary prevention require large samples and long follow-up to obtain a high-quality outcome; therefore the recruitment process and the drop-out rates largely dictate the adequacy of the results. We are conducting a Phase III trial on persons with metabolic syndrome to test the hypothesis that comprehensive lifestyle changes and/or metformin treatment prevents age-related chronic diseases (the MeMeMe trial, EudraCT number: 2012-005427-32, also registered on ClinicalTrials...

The pharmaceutical excipient, polyethylene glycol 400 (PEG 400), unexpectedly alters the bioavailability of the BCS class III drug ranitidine in a sex-dependent manner. As ranitidine is a substrate for the efflux transporter P-glycoprotein (P-gp), we hypothesized that the sex-related influence could be due to interactions between PEG 400 and P-gp. In this study, we tested this hypothesis by: i) measuring the influence of PEG 400 on the oral bioavailability of another P-gp substrate (ampicillin) and of a non-P-gp substrate (metformin); and ii) measuring the effect of PEG 400 on drug bioavailability in the presence of a P-gp inhibitor (cyclosporine A) in male and female rats...

BACKGROUND: Evidence suggests that endocannabinoid system activation through the cannabinoid receptor 1 (CB1) is associated with enhanced liver injury, and CB1 antagonism may be beneficial. The aim of this study was to determine the impact of rimonabant (CB1 antagonist) on alanine aminotransferase (ALT), a hepatocellular injury marker, and a hepatic inflammatory cytokine profile. METHODS: Post hoc review of 2 studies involving 50 obese women with PCOS and well matched for weight, randomised to weight reducing therapy; rimonabant (20 mg od) or orlistat (120 mg tds), or to insulin sensitising therapy metformin, (500 mg tds), or pioglitazone (45 mg od)...

PURPOSE OF REVIEW: Patients with diabetes and/or stress hyperglycemia requires good glycemic control in the hospital setting, often requiring the use of glucose-lowering therapy. Standard-of-care dictates that non-insulin therapy be discontinued, with insulin therapy initiated using a basal-bolus approach. However, insulin is associated with a high risk for hypoglycemia and medical errors. Alternatives to insulin are needed in the inpatient setting, but the cardiovascular (CV) safety of non-insulin therapy is a concern...
