Worldwide deaths from diabetes mellitus (DM) and colorectal cancer increased by 90% and 57%, respectively, over the past 20 years. The risk of colorectal cancer was estimated to be 27% higher in patients with type 2 DM than in non-diabetic controls. However, there are potential confounders, information from lower income countries is scarce, across the globe there is no correlation between DM prevalence and colorectal cancer incidence and the association has evolved over time, suggesting the impact of additional environmental factors...

Zeaxanthin (ZA), an important compound found in Lycium barbarum, shows various pharmacodynamic effects. In our present study, a high-fat, high-sucrose diet and streptozotocin (STZ)-induced diabetic rat model was used to investigate the antidiabetic activities of ZA. After a 4-week administration of 200 and 400 mg/kg of ZA and 100 mg/kg of metformin hydrochloride, various blood biochemical indexes were detected. ZA strongly normalized the reduced bodyweight and enhanced fasting blood glucose in diabetic rats...

Metformin is a biguanaide antidiabetic drug used worldwide, and its effectiveness and benefits have already been established. However, the safety of high doses of metformin in Japanese patients, especially in elderly patients with a decreased renal function, remains unclear. Among the side effects of metformin, lactate acidosis is the most problematic due to a high mortality rate. Therefore, we assessed plasma lactate levels in metformin-treated patients to identify independent risk factors for hyperlactemia...

Blood and urine biochemistry screening tests are important for initial detection of diabetes, determination of severity of its complications, and monitoring of therapy. We evaluated the effects of aqueous chicory seed extract (CSE), on renal biochemical parameters, histology, and Na+/glucose cotansporters, SGLT1 and SGLT2 expression levels using metformin, and aspirin as controls. Late stage type 2 diabetes (LT2D; FBS, >300 mg/dl) and early stage type 2 diabetes (ET2D; FBS, 140-220 mg/dl) were induced in rats by streptozotocin (STZ group) and a combination of STZ and niacinamide (NIA/STZ group), respectively...

BACKGROUND AND OBJECTIVES: Diabetes is the leading cause of ESRD. Glucose control improves kidney outcomes. Most patients eventually require treatment intensification with second-line medications; however, the differential effects of those therapies on kidney function are unknown. DESIGN, SETTING, PARTICIPANTS & MEASUREMENTS: We studied a retrospective cohort of veterans on metformin monotherapy from 2001 to 2008 who added either insulin or sulfonylurea and were followed through September of 2011...

The metformin and Scutellariae Radix extract (SB) combination has been previously reported to enhance anti-diabetic activity. Considering that organic cation transporters (OCTs) and multi-drug and toxin extrusion proteins (MATEs) in the liver and kidney are determinant factors on hepatic distribution and renal clearance of metformin, the effects of SB on OCT or MATE-mediated systemic exposure of metformin as well as on glucose tolerance and hypoglycemia were examined. Although SB inhibited metformin uptake through human transporters OCT1 and MATE1 in vitro, the systemic exposures of metformin in vivo rats were not altered after metformin treatment with and without SB due to unchanged renal excretion of metformin...

Renal function reduction rises difficulties in dealing with many drugs. These problems are mainly due to the need of decreasing progressively the doses of the drugs that are cleared by the kidneys, in parallel with the progressive reduction in renal function. The degree of renal impairment should be better measured as the estimated glomerular filtration rate, avoiding to simply rely on plasma creatinine. Physicians should also be aware of the important potential side effects of some very effective and safe drugs, when they are used in patients with relevant reduction in renal function, independently of their possible plasma accumulation...

The type-2 diabetes drug metformin has proven to have protective effects in several renal disease models. Here, we investigated the protective effects in a 3-day unilateral ureteral obstruction (3dUUO) mouse model. Compared with controls, ureteral obstructed animals displayed increased tubular damage and inflammation. Metformin treatment attenuated inflammation, increased the anti-oxidative response and decreased tubular damage. Hepatic metformin uptake depends on the expression of organic cation transporters (OCTs)...

Like other biguanide agents, metformin is an anti-hyperglycemic agent with lower tendency towards hypoglycemia compared to other anti-diabetic drugs. Given its favorable effects on serum lipids, obese body habitus, cardiovascular disease, and mortality, metformin is recommended as the first-line pharmacologic agent for type 2 diabetes in the absence of contraindications. However, as metformin accumulation may lead to type B non-hypoxemic lactic acidosis, especially in the setting of kidney injury, chronic kidney disease, and overdose, regulatory agencies such as the United States Food and Drug Administration (FDA) have maintained certain restrictions regarding its use in kidney dysfunction...

Lead (Pb) is an environmental pollutant associated with several diseases, such as nephrotoxicity. Methylglyoxal (MG) is a reactive dicarbonyl compound formed during glycolysis and reported to increase in kidney damage. Metformin is used as a MG scavenger in the clinic. In this study, we investigated the mechanism of Pb-induced renal injury and the effect of metformin on Pb-induced nephrotoxicity. Eighteen Wistar rats were randomly divided into three groups: control, Pb, and Pb + metformin groups. Pb (250 ppm) was administered in drinking water, and 50 mg/Kg of metformin was co-administered orally...

Cordia boissieri A. DC. (Boraginaceae) is traditionally used as an herbal remedy for diabetes by Hispanic women in Southwestern USA. A recent investigation showed the significant protective effect of ethyl acetate extract against metabolic syndrome (MS). However, the corresponding active principles responsible for this effect and relations between their structure and biological actions remain unclear. Thus, ethyl acetate extract was subjected to column chromatography, which yielded seven compounds identified on the basis of spectroscopic data as rutin, hesperidin, kaempferol-3-O-β-d-glucopyranoside, rosmarinic acid, β-sitosterol-3-O-β-d-glucopyranoside, quercetin, and kaempferol...

Diabetes is an important cause of end stage renal failure worldwide. As renal impairment progresses, managing hyperglycaemia can prove increasingly challenging, as many medications are contra-indicated in moderate to severe renal impairment. Whilst evidence for tight glycaemic control reducing progression to renal failure in patients with established renal disease is limited, poor glycaemic control is not desirable, and is likely to lead to progressive complications. Metformin is a first-line therapy in patients with Type 2 diabetes, as it appears to be effective in reducing diabetes related end points and mortality in overweight patients...
