[PMID: 34604406 DOI: 10.52547/rbmb.10.2.164] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2020] [Accepted: 12/13/2020] [Indexed: 01/14/2023]
Abstract
Background Oxidative stress is an imbalance between free radical's production and the body's ability to counteract or detoxify their harmful effects through neutralization by antioxidants, oxidative stress is thought to be involved in the pathogenesis of diabetic nephropathy. One of the key enzymatic antioxidants is glutathione peroxidase (GPx), which plays an important protective function in diabetes complications, by reducing the rising state of oxidative stress and removing toxicity from peroxides and converting them into a non-toxic substance. The objective of this research was to evaluate the rule of glutathione peroxidase in regulate oxidants/antioxidants levels diabetic patients with nephropathy. Methods In a case-control study, we assessed serum GPx activity (Se-Dependent, non-selenium dependent and total GPx), total oxidant, lipid peroxidation, total antioxidant, and catalase in healthy control subjects (group 1), in diabetic patients without diabetic nephropathy (group 2) and diabetic patients with nephropathy (group 3). Results GPx activity was significantly lower in T2D patients with and without nephropathy compared to healthy subject's control. Total oxidants and lipids peroxidation have a negative correlation with the GPx and other antioxidants. Conclusion Decreased GPx activity indicate a relationship between GPx activity and diabetic nephropathy.

Use of sodium-glucose co-transporter-2 inhibitors in Asian patients with type 2 diabetes and kidney disease: An Asian perspective and expert recommendations. Diabetes Obes Metab 2021; 23:299-317. [PMID: 33155749 PMCID: PMC7839543 DOI: 10.1111/dom.14251] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 10/17/2020] [Accepted: 11/01/2020] [Indexed: 12/14/2022]
Abstract
Early onset of type 2 diabetes and a high prevalence of co-morbidities predispose the Asian population to a high risk for, and rapid progression of, diabetic kidney disease (DKD). Apart from renin-angiotensin system inhibitors, sodium-glucose co-transporter-2 (SGLT-2) inhibitors have been shown to delay renal disease progression in patients with DKD. In this review article, we consolidate the existing literature on SGLT-2 inhibitor use in Asian patients with DKD to establish contemporary guidance for clinicians. We extensively reviewed recommendations from international and regional guidelines, data from studies on Asian patients with DKD, global trials (DAPA-CKD, CREDENCE and DELIGHT) and cardiovascular outcomes trials. In patients with DKD, SGLT-2 inhibitor therapy significantly reduced albuminuria and the risk of hard renal outcomes (defined as the onset of end-stage kidney disease, substantial decline in renal function from baseline and renal death), cardiovascular outcomes and hospitalization for heart failure. In all the cardiovascular and renal outcomes trials, there was an initial decline in the estimated glomerular filtration rate (eGFR), which was followed by a slowing in the decline of renal function compared with that seen with placebo. Despite an attenuation in glucose-lowering efficacy in patients with low eGFR, there were sustained reductions in body weight and blood pressure, and an increase in haematocrit. Based on the available evidence, we conclude that SGLT-2 inhibitors represent an evidence-based therapeutic option for delaying the progression of renal disease in Asian patients with DKD and preserving renal function in patients at high risk of kidney disease.

Fang WC, Chou KM, Sun CY, Lee CC, Wu IW, Chen YC, Pan HC. Thermal Perception Abnormalities Can Predict Diabetic Kidney Disease in Type 2 Diabetes Mellitus Patients. Kidney Blood Press Res 2020; 45:926-938. [PMID: 33053551 DOI: 10.1159/000510479] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Accepted: 07/26/2020] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Previous studies have illustrated clinical associations between diabetic peripheral neuropathy (DPN) and diabetic kidney disease (DKD). Quantitative sensory testing (QST) can accurately detect thermal perception abnormalities and aid in the early diagnosis of asymptomatic small-fiber DPN in patients with type 2 diabetes. The aim of this study was to determine the predictive value of thermal perception abnormalities by QST to detect DKD. METHODS We prospectively enrolled 432 patients with type 2 diabetes (50.2% male, mean age 57.2 years, and average duration of diabetes 9.9 years) at our hospital between 2016 and 2017. Demographic and clinical data of the patients were recorded and analyzed. Diagnosis and staging of DKD were determined by urinary albumin excretion rate and estimated glomerular filtration rate. The presence of thermal perception abnormalities was determined by QST. Multiple logistic regression and receiver operating characteristic (ROC) analyses were performed to investigate the relationships between thermal perception abnormalities and DKD in these patients. RESULTS In multiple regression analysis, abnormal cold perception in the lower limbs was associated with an increased risk of advanced DKD. Area under the ROC curve analysis revealed that four-limb cold perception abnormalities had the best discriminatory power (0.741 ± 0.053) to predict advanced DKD. CONCLUSIONS Our results demonstrate the value of using thermal perception abnormalities to identify patients with type 2 diabetes also at risk of DKD.
