BACKGROUND: Jiangtang decoction (JTD) is a China patented drug which contains Euphorbia humifusa Willd, Salvia miltiorrhiza Bunge, Astragalus mongholicus Bunge, Anemarrhena asphodeloides Bunge, and Coptis chinensis Franch. For decades, it has also been used clinically to treat diabetic nephropathy (DN) effectively; however, the associated mechanisms remain unknown. Thus, the present study aimed to examine the protective efficacy of JTD in DN and elucidate the underlying molecular mechanisms...

Sacubitril/valsartan (LCZ696) is indicated for the treatment of heart failure with reduced ejection fraction. Absorption of sacubitril/valsartan and conversion of sacubitril (prodrug) to sacubitrilat (neprilysin inhibitor) was rapid with maximum plasma concentrations of sacubitril, sacubitrilat, and valsartan (angiotensin receptor blocker) reaching within 0.5, 1.5-2.0, and 2.0-3.0 h, respectively. With a twofold increase in dose, an increase in the area under the plasma concentration-time curve was proportional for sacubitril, ~1...

Statins are widely used to reduce cardiovascular risk. Unfortunately, some patients still experience cardiovascular events though prescribed with high-intensity statins. Metformin, an anti-diabetic drug, was reported to possess anti-atherosclerotic effects. Therefore, the experiments were designed to evaluate whether combined use of metformin and atorvastatin can achieve additional benefits. In rabbits fed a high-cholesterol diet, we evaluated the effects of the combination therapy on atherosclerotic plaques, lipid profiles, blood glucose levels, liver and kidney functions...

BACKGROUND: Whether metformin precipitates lactic acidosis in patients with chronic kidney disease (CKD) remains under debate. We examined whether metformin use was associated with an increased risk of acute kidney injury (AKI) as a proxy for lactic acidosis and whether survival among those with AKI varied by metformin exposure. METHODS: All individuals with type 2 diabetes and available prescribing data between 2004 and 2013 in Tayside, Scotland were included. The electronic health record for diabetes which includes issued prescriptions was linked to laboratory biochemistry, hospital admission, death register and Scottish Renal Registry data...

BACKGROUND: Concerns about metformin-associated lactic acidosis (MALA) prohibit the use of metformin in a large subset of diabetic patients, mostly in patients with chronic kidney disease. Increasing evidence suggests that the current safety regulations may be overly restrictive. OBJECTIVES: To examine the association between chronic metformin treatment and lactate level in acute illness on the first day of admission to an internal medicine ward. METHODS: We compared diabetic and non-diabetic hospitalized patients treated or not treated with metformin in different sets of kidney function...

Freshwater animal proteins have long been used as nutrient supplements. In this study, melanian snail (Semisulcospira libertina) protein hydrolysates (MPh) were found to exert anti-diabetic and protective effects against liver and kidney damage in mice with type II diabetes adapted to a 45% kcal high-fat diet (HFD). The hypoglycemic, hepatoprotective and nephroprotective effects of MPh were analyzed after 12 weeks of the continuous oral administration of MPh at 125, 250 and 500 mg/kg. Diabetic control mice exhibited an increase in body weight, and blood glucose and insulin levels, with a decrease in serum high-density lipoprotein (HDL) levels...

Chronic kidney disease (CKD) is characterized by the accumulation of uremic solutes; however, little is known about how these solutes affect drug absorption and disposition. The goal of this study was to evaluate the effect of uremic solutes on the organic cation transporter, OCT2, which plays a key role in the renal secretion of many basic drugs. As a second goal, we reviewed the literature to determine if there was evidence for the effect of CKD on the renal secretion of basic drugs. We first screened 72 uremic solutes as inhibitors of [(14)C]-labeled metformin uptake by OCT2...

The history of Metformin-Associated Lactic Acidosis (MALA) is rooted in the earlier experience with phenformin, another biguanide treatment for type 2 diabetes that was removed from the market owing to a clear causal association with cases of lactic acidosis (LA). Although metformin is less problematic in this regard, metformin can and does induce lactic acidosis, and under the right circumstances it continues to present a potential risk to patients. Recent liberalization of the prescribing guidelines in the US and EU specifically regarding use in more advanced stages of Chronic Kidney Disease (CKD) have led to renewed interest in the topic of MALA, and this issue of the Journal presents two timely articles on the topic by Lalau et al...

In the kidney, reabsorption via the epithelial sodium channel (ENaC) is involved in long-term blood pressure control. Previously we demonstrated that ENaC hyperactivity is associated with development of salt-sensitive (SS) hypertension in Dahl SS rats. AMP-activated kinase (AMPK), playing a role in cellular energy homeostasis, has been shown to decrease ENaC activity. Here, we tested whether metformin and AICAR, two drugs that activate AMPK, affect the development of salt-induced hypertension. High salt diet significantly increased mean arterial pressure (MAP) in Dahl SS rats...

Following a hypothesis developed in an earlier paper, here it is discussed how deviations of blood pH from the normal range (namely states of acidemia) together with high blood levels of free fatty acids (FFA) may offer a rationale for many important risk factors for cardiovascular diseases (CVD) by shaping a context for formation of fatty acid micelles and vesicles with an acidic core, which fuse with the endothelia, disrupt vital cell processes, and thereby may initiate atherosclerotic plaque formation. Acidemia may arise primarily from dysregulation of the systemic buffers that control blood pH, chronic diseases of kidneys and lungs, inappropriate diet, or may be induced by some common drugs...

AIMS: Metformin is renally excreted and has been associated with the development of lactic acidosis. Although current advice is to omit metformin during illnesses that may increase risk of acute kidney injury (AKI), the evidence supporting this is lacking. We investigated the relationship between AKI, lactate concentrations and the risk of lactic acidosis in those exposed to metformin. METHODS: We undertook a population-based case-control study of lactic acidosis in 1,746 participants with Type 2 diabetes and 846 individuals without diabetes with clinically measured lactates with and without AKI between 1994-2014...

Worldwide, an estimated 200 million people have chronic kidney disease (CKD), whose most common causes include hypertension, arteriosclerosis, and diabetes. About 40% of patients with diabetes develop CKD and intensive blood glucose control through pharmacological intervention can delay CKD progression. Standard therapies for the treatment of type 2 diabetes mellitus include metformin, sulfonylureas, meglitinides, thiazolidinediones, and insulin. While these drugs have an important role in the management of type 2 diabetes, only the thiazolidinedione pioglitazone can be used across the spectrum of CKD (stages 2-5) and without dose adjustment...
