Renoprotective effect of calycosin in high fat diet-fed/STZ injected rats: Effect on IL-33/ST2 signaling, oxidative stress and fibrosis suppression

Publication date: Available online 11 November 2019Source: Chemico-Biological InteractionsAuthor(s): Nehal M. Elsherbiny, Eman Said, Hoda Atef, Sawsan A. ZaitoneAbstractType 2 diabetes mellitus (T2DM) is a disease with a drastically growing worldwide prevalence. It is usually associated with numerous complications of which; diabetic nephropathy (DN); is a main complication of microvasculature and more seriously, a common cause of end-stage renal disease (ESRD). Unfortunately, both the lack of a definitive remedy alongside the economic and the social burden on DN patients enforces considerable impetus for developing alternative therapies. IL-33 is a newly discovered member of the IL-1 cytokine family. IL33/ST2 signaling plays a crucial role in acute and chronic kidney diseases. Calycosin is an isoflavone with reported IL33 signaling inhibitory activity. The present study aimed to investigate if calycosin possess renal protective effect in high-fat diet/STZ-induced T2DM model and to clarify the potential underlying mechanisms. HFD-STZ control rats showed functional and structural renal damage confirmed by increased serum creatinine, blood urea nitrogen and albuminuria associated with marked renal glomerulosclerosis and interstitial fibrosis. Initiation of inflammation, oxidative stress, and fibrosis was evident as depicted by elevated renal levels of IL33/ST2 mRNA as well as increased renal NF-κBp65, TNF–α, IL-1β, MDA, and TGF-β contents with suppres...

Abstract Contrast-induced acute kidney injury (CIAKI) is a severe complication associated with the use of iodinated contrast media (CM); a sudden but potentially reversible fall in glomerular filtration rate (GFR) typically occurring 48-72 hours after CM administration. Principal risk factors related with presentation of CIAKI are preexisting chronic kidney disease and diabetes mellitus. Studies on CIAKI present considerable complexity because of differences in CM type and dose, controversies in definition and baseline comorbidities. Despite that, it should be noted that CIAKI poses a serious health problem becaus...

by Jan Menne, Eva Dumann, Hermann Haller, Bernhard M. W. Schmidt BackgroundSodium-glucose cotransporter-2 inhibitors (SGLT2is) represent a new class of oral hypoglycemic agents used in the treatment of type 2 diabetes mellitus. They have a positive effect on the progression of chronic kidney disease, but there is a concern that they might cause acute kidney injury (AKI). Methods and findingsWe conducted a systematic review and meta-analysis of the effect of SGLT2is on renal adverse events (AEs) in randomized controlled trials and controlled observational studies. PubMed, EMBASE, Cochrane library, and ClinicalTrials.gov wer...

However, it is not clear how safe this treatment is for elderly patients, especially Asians, who are known to be more insulin deficient than Caucasian individuals with a similar insulin resistance. Here, we report a case concerning an elderly patient wi...

CONCLUSION: In T2DM patients, CKD presence was associated with higher risk of modified MACE, HF, and ACM. This may have risk-stratification implications for T2DM patients based on background CKD and highlights the potential importance of novel renoprotective strategies.

AbstractAims/hypothesisThe aim of this study was to provide data from a contemporary population-representative cohort on rates and predictors of renal decline in type 1 diabetes.MethodsWe used data from a cohort of 5777 people with type 1 diabetes aged 16 and older, diagnosed before the age of 50, and representative of the adult population with type 1 diabetes in Scotland (Scottish Diabetes Research Network Type 1 Bioresource; SDRNT1BIO). We measured serum creatinine and urinary albumin/creatinine ratio (ACR) at recruitment and linked the data to the national electronic healthcare records.ResultsMedian age was 44.1  y...

Abstract Sodium-glucose cotransporter-2 (SGLT-2) inhibitors have become the best choice of second-line oral antidiabetic drugs for patients with heart or chronic kidney disease. However, it is not clear how safe this treatment is for elderly patients, especially Asians, who are known to be more insulin deficient than Caucasian individuals with a similar insulin resistance. Here, we report a case concerning an elderly patient with type 2 diabetes mellitus without insulin dependence, whose antidiabetic medication had recently been changed to include an SGLT-2 inhibitor. The patient presented with an atypical hyperos...

CONCLUSION: There is a high CKD burden in the ME countries. There needs to be emphasis on prevention of ESRD and provision of adequate care for the total ESRD patient population. National renal registries are needed to monitor the status of ESRD patients. Health expenditures should be increased to cover all aspects of RRT in ME Countries.

This study explored the proportion of NAFLD cases and increased liver fibrosis (LF), and the association between LF and either chronic kidney disease (CKD) or cardiovascular complications in T2DM patients. METHODS: - The study included 137 patients with non-insulin-treated T2DM and no known liver disease consecutively attending our diabetes outpatients service who underwent liver ultrasonography and liver stiffness measurement (LSM) using vibration-controlled transient elastography (FibroScan®). RESULTS: - The proportion of patients with hepatic steatosis on ultrasonography was 73.7%, and the proportion with ...
