Effect of anti-diabetic drugs in dialysis patients with diabetes: a nationwide retrospective cohort study

Background Type 2 diabetes mellitus is common in patients undergoing dialysis. However, the association between anti-diabetic drug use and survival outcomes is rarely discussed. We aimed to investigate whether continued anti-diabetic medication use affects the survival of diabetic dialysis patients and whether different hypoglycemic drug use influences prognosis. Methods Using a nationwide database, we enrolled patients with incident end-stage renal disease under maintenance dialysis during 2011–2015 into the pre-existing diabetes dialysis (PDD), incident diabetes after dialysis (IDD), and non-diabetic dialysis (NDD) groups. The PDD group was further subclassified into patients who continued (PDD-M) and discontinued (PDD-NM) anti-diabetic drug use after dialysis. Results A total of 5249 dialysis patients were examined. The PDD-NM group displayed a significantly higher mortality rate than the IDD, PDD-M, and NDD groups (log-rank test P < 0.001). The PDD-M group had a significantly lower risk of death, regardless of insulin (P < 0.001) or oral hypoglycemic agent (OHA) (P < 0.001) use. Initial insulin administration or OHA had no statistically significant effect on overall mortality in the IDD group. But OHA use had better survival trends than insulin administration for the older (P = 0.02) and male subgroups (P = 0.05). Conclusions For dialysis patients with diabetes, continuous administration of anti-diabetic drugs after dialysis and choice of medication may affect outcomes.

Prevention of Hypertensive Disorders of Pregnancy—Is There a Place for Metformin?

The possibility of prophylaxis of hypertensive disorders of pregnancy (HDPs) such as preeclampsia (PE) and pregnancy-induced hypertension is of interest due to the unpredictable course of these diseases and the risks they carry for both mother and fetus. It has been proven that their development is associated with the presence of the placenta, and the processes that initiate it begin at the time of the abnormal invasion of the trophoblast in early pregnancy. The ideal HDP prophylaxis should alleviate the influence of risk factors and, at the same time, promote physiological trophoblast invasion and maintain the physiologic endothelium function without any harm to both mother and fetus. So far, aspirin is the only effective and recommended pharmacological agent for the prevention of HDPs in high-risk groups. Metformin is a hypoglycemic drug with a proven protective effect on the cardiovascular system. Respecting the anti-inflammatory properties of metformin and its favorable impact on the endothelium, it seems to be an interesting option for HDP prophylaxis. The results of previous studies on such use of metformin are ambiguous, although they indicate that in a certain group of pregnant women, it might be effective in preventing hypertensive complications. The aim of this study is to present the possibility of metformin in the prevention of hypertensive disorders of pregnancy with respect to its impact on the pathogenic elements of development

Ethnomedicinal Value of Antidiabetic Plants in Bangladesh: A Comprehensive Review

The use of conventional drugs to treat metabolic disorders and the pathological consequences of diabetes further increases the complications because of the side effects, and is sometimes burdensome due to relatively higher costs and occasionally painful route of administration of these drugs. Therefore, shifting to herbal medicine may be more effective, economical, have fewer side effects and might have minimal toxicity. The present review amasses a list of ethnomedicinal plants of 143 species belonging to 61 families, from distinctive domestic survey literature, reported to have been used to treat diabetes by the ethnic and local people of Bangladesh. Leaves of the medicinal plants were found leading in terms of their use, followed by fruits, whole plants, roots, seeds, bark, stems, flowers, and rhizomes. This review provides starting information leading to the search for and use of indigenous botanical resources to discover bioactive compounds for novel hypoglycemic drug development.

Bioactivity-guided separation of potential α-glycosidase inhibitor from clerodendranthus spicatus based on HSCCC coupled with molecular docking

Clerodendranthus Spicatus is a traditional Dais medi-edible plant and it has been proven to have good blood glucose-lowering efficacy. However, the material basis of Clerodendranthus Spicatus has not been clarified yet and therefore needs to be determined. In this paper, the effective ingredients of this medicine were purified by high-speed counter-current chromatography. Alongside, their potential hypoglycemic activity was determined by α-glucosidase inhibitory activities in vitro and molecular docking. Finally, five compounds were purified and identified as 2-caffeoyl-L-tartaric acid (1), N-(E)-caffeoyldopamine (2), rosmarinc acid (3), methyl rosmarinate (4), 6,7,8,3′,4′-Pentamethoxyflavone (5). Examination of α-glucosidase inhibitory activity in vitro showed that 2-caffeoyl-L-tartaric acid and rosmarinic acid had a higher inhibitory activity than acarbose. Molecular docking indicated that the affinity energy of the identified compounds ranged from − 7.6 to − 8.6 kcal/mol, a more desirable result than acarbose (− 6.6 kcal/mol). Particularly, rosmarinc acid with the lowest affinity energy of − 8.6 kcal/mol was wrapped with 6 hydrogen bonds. Overall, α-glucosidase inhibitory activities and molecular docking suggested that rosmarinc acid was likely to be a promising hypoglycemic drug.

Association of metformin monotherapy or combined therapy with cardiovascular risks in patients with type 2 diabetes mellitus

Background Metformin is a first-line drug in type 2 diabetes mellitus (T2DM) treatment, yet whether metformin may increase all-cause or cardiovascular mortality of T2DM patients remains inconclusive. Methods We searched PubMed and Embase for data extracted from inception to July 14, 2020, with a registration in PROSPERO (CRD42020177283). This study included randomized controlled trials (RCT) assessing the cardiovascular effects of metformin for T2DM. This study is followed by PRISMA and Cochrane guideline. Risk ratio (RR) with 95% CI was pooled across trials by a random-effects model. Primary outcomes include all-cause mortality and cardiovascular mortality. Results We identified 29 studies that randomly assigned patients with 371 all-cause and 227 cardiovascular death events. Compared with untreated T2DM patients, metformin-treated patients was not associated with lower risk of all-cause mortality (RR: 0.98; 95%CI: 0.69–1.38; P = 0.90), cardiovascular mortality (RR: 1.13; 95% CI: 0.60, 2.15; P = 0.70), macrovascular events (RR: 0.87; 95%CI: 0.70–1.07; P = 0.19), heart failure (RR: 1.02; 95% CI:0.61–1.71; P = 0.95), and microvascular events (RR: 0.78; 95% CI:0.54–1.13; P = 0.19). Combination of metformin with another hypoglycemic drug was associated with higher risk of all-cause mortality (RR: 1.49; 95% CI: 1.02, 2.16) and cardiovascular mortality (RR: 2.21; 95% CI: 1.22, 4.00) compared with hypoglycemic drug regimens with no metformin. Conclusion The combination of metformin treatment may impose higher risk in all-cause and cardiovascular mortality. This finding, at least in part, shows no evidence for benefits of metformin in combination in terms of all-cause/cardiovascular mortality and cardiovascular events for T2DM. However, the conclusion shall be explained cautiously considering the limitations from UK Prospective Diabetes Study (UKPDS).

Overview of New Onset Diabetes after Transplantation Induced by Tacrolimus

Tacrolimus is an important therapy in the post-transplant immunosuppressant regimen. However, it is responsible for the highest incidence of a specific type of diabetes called new onset diabetes after transplantation (NODAT). The dangers of NODAT are not limited to cardiovascular or nerve diseases, but also to kidney complication that may lead to loss of transplant kidney. The aim of this article is to discuss the possible theory of NODAT induces by tacrolimus and its common therapy. In addition, this research is to enhance knowledge about the pharmacokinetic and dynamic of tacrolimus. This review depends on research in reliable and popular medical databases which are PubMed, Google Scholar, Saudi Digital Library, and Web of Science (ISI). While the terms used to search the published researches are organ transplantation, immunosuppressant, tacrolimus, new-onset diabetes after transplantation, and hypoglycemic drug.

Pioglitazone is a forgotten hypoglycemic drug with proven cardioprotective and nephroprotective properties

Considering that type 2 diabetes mellitus is a multicomponent disease and is associated with an extremely high risk of macrovascular complications (myocardial infarction, stroke and death from cardiovascular diseases), at present, much attention is paid to the choice of hypoglycemic drugs, given the individual characteristics of the patient. Preference is given to drugs of those classes that have a positive effect on cardiovascular outcomes. Along with relatively new molecules (inhibitors of the sodium-glucose cotransporter type 2 and agonists of glucagon-like peptide-1 receptors), the well-known drug pioglitazone, which belongs to the thiazolidinediones group, has not left the field of attention of researchers. Importantly, the cardioprotective effect of pioglitazone has been confirmed in several large randomized trials that showed a delay in atherosclerosis and a reduced risk of cardiovascular disease (PERISCOPE, CHICAGO, IRIS and PROactive). As an insulin sensitizer, pioglitazone reduces insulin resistance, has a protective effect on pancreatic β-cells, and also has a beneficial effect on components of insulin resistance syndrome (lowers blood pressure, lipid spectrum parameters) and improves the course of non-alcoholic fatty liver disease. There is evidence of possible side effects (weight gain, fluid retention, fractures), but their severity decreases with decreasing dose of the drug.

Middle segment-preserving pancreatectomy for multifocal pancreatic ductal adenocarcinoma located in the head and tail of the pancreas: a case report

A 77-year-old woman with a solitary existence was referred to our hospital for the treatment of pancreatic tumors. Computed tomography revealed an 18-mm mass in the pancreatic head that had invaded the right side of the superior mesenteric vein (SMV) and a 32-mm mass in the pancreatic tail. We performed middle segment-preserving pancreatectomy (MSPP) with SMV resection and reconstruction. The TNM classifications were T2, N1, M0, stage IIB in the pancreatic head, and T2, N0, M0, stage IB in the pancreatic tail, respectively. Postoperatively, the blood glucose was well controlled using only hypoglycemic drug, and insulin preparation was not necessary. No fatty diarrhea was found using a pancreatic enzyme supplement. After 9 months of follow-up, no recurrence was found. MSPP for pancreatic head and tail carcinomas seemed acceptable for both preserving the postoperative quality of life and ensuring curative resection especially in elderly patient with a solitary existence.
