Diabetic Nephropathy and Management

Chronic kidney disease affects people worldwide. Approximately 1 out of 3 adults with diabetes have kidney disease. Among several etiological factors for CKD, diabetes mellitus (DM) and hypertension are the main factors. These factors not only cause CKD but are also responsible for several complications related to CKD. In this article, we have reviewed Diabetic Nephropathy (DN) in terms of etiology, pathophysiology, diagnosis, management, current guidelines for diabetic nephropathy management, and some of the research study findings. Diabetic nephropathy (DN) is the chief factor for end-stage renal disease (ESRD) development across the globe. The primary cause of DN is Diabetes Mellitus, which is an autoimmune lifestyle disorder having several etiological factors. Checking for urine albuminuria, estimated GFR (eGFR), and blood glucose are unswerving tests for DN diagnosis and subsequent monitoring. Controlling hyperglycemia, blood pressure, and proteinuria are critical in stopping the progression of DKD. Clinical practice and evidence-based medicine demonstrated that early diagnosis followed by treatment can prevent or halt DKD progression.

Role of angiotensin converting enzyme and angiotensinogen gene polymorphisms in angiotensin converting enzyme inhibitor-mediated antiproteinuric action in type 2 diabetic nephropathy patients

AIM To investigate the role of genetic variants of angiotensin converting enzyme(ACE) and angiotensinogen(AGT) genes in the antiproteinuric efficacy of ACE inhibitor therapy in diabetic nephropathy(DN) patients.METHODS In the present study, 270 type 2 diabetes mellitus patients with nephropathy were enrolled and treated with ACE inhibitor(ramipril) and followed at 6 mo for renal function and albumin excretion by estimating serum creatinine, end stage renal disease, and albumin/creatinine ratio(ACR) in urine. Genotyping of ACE I/D and AGT M235 T polymorphisms were performed by using primer specific polymerase chain reaction(PCR) and PCR-RFLP techniques, respectively. RESULTS Forty-eight percent of DN patients(responders) benefited with respect to proteinuria from ACE inhibitor therapy at 6 mo follow-up. A significant reduction in ACR was observed after 6 mo treatment with ACE inhibitor irrespective of whether DN patients were micro-albuminuric(≥ 30 and < 300 mg/g creatinine) or macro-albuminuric(≥ 300 mg/g creatinine) at the time of enrollment. However, macro-albuminuric patients(55%) showed better response to therapy. A reduction in urinary ACR was found independent of genotypes of ACE I/D and AGT M235 T polymorphisms although macro-albuminuric patients having TT genotype showed statistically insignificant increased response(72%). CONCLUSION ACE inhibitor therapy reduced urinary ACR by ≥ 30% in 50% of DN patients and the response is independent of ACE I/D and AGT M235 T polymorphisms.

Non-Diabetic Kidney Disease in Type 2 Diabetes Mellitus: A Study of 82 Patients and Review of the Literatures

Background: Worldwide, diabetic nephropathy-DN is the leading cause of end-stage kidney disease-ESKD, DN is a common cause of renal failure with a reported frequency of 10% - 15% in type-2-diabetes-mellitus-T2DM patients, however there is a great discrepancy between countries. The aim of the pre-sent study is to evaluate the findings of kidney biopsies performed on diabetic patients. Materials and Methods: We studied native kidney histopathological findings in the period from January 2016 till end of December 2018 done for patients with T2DM with chronic kidney diseases-CKD. Results: A total of 82 DM-patients, 50 males (61%) and 32 females (39%) with age mean (95% CI) of 50.8 (47.1 - 55.2) years for all patients, ranged between 15 to 65 years. Histological findings showed that 57.3% of patients had DN. While focal-segmental-glomerulosclerosis-FSGS was present in 20.7%—primary in 8.6% and secondary in 12.1%. IgA represented 4.9%, while Lupus nephritis, Membranous and drug induced interstitial nephritis were each present in 3.7%. MCD was present in 2.4%. Lastly diffuse proliferative GN, ANCA associated glomerulonephritis, and hypertensive nephrosclerosis accounted for 1.2%. Conclusion: The prevalence of NDKD is remarkably frequent in DM patients who underwent kidney biopsy and FSGS was the most frequent diagnosis. To get a proper histopathological diagnosis, an adequate tissue biopsy is needed with an adequate number of glomeruli. There is a great need for more consideration to biopsy diabetic patients, as the finding of NDKD requires a different therapeutic approach. This, hopefully, will help to manage these patients better and therefore, ameliorate the progression to ESKD over time and therefore delay the need for RRT.

One Case of Diabetes Nephropathy Stage V, Combined Valvular Disease, Total Heart Failure with Diabetes Foot Gangrene

The patient was found to have 4+urine sugar by physical examination 14 years ago and was treated with oral hypoglycemic drugs. Insulin was injected intramuscularly nine years ago. Two and a half years ago, it was found that the color of the thumb, index and middle toe of the left foot became black. He went to a third-class hospital in Beijing and was diagnosed as “diabetes foot”. He was treated with “balloon dilation of lower limb blood vessels of diabetes foot”. Half a year ago, the third toe on the right side was broken and treated in the hospital again. “Popliteal artery stent implantation” was given for the diagnosis of “double kidney insufficiency, diabetes foot, left heart failure, combined heart valve disease”, “Hemofiltration therapy” and anti-inflammatory, amino acid supplementation, kidney function protection, anticoagulation, anemia correction and other treatments. Later, he went to our hospital and was diagnosed by the TCM diagnosis: category of consumptive disease, toe or finger gangrene (syndrome/pattern of qi and yin deficiency). Western medicine diagnosed: stage V of diabetes nephropathy, type II diabetes foot gangrene, combined with heart valve disease, hypoalbuminemia, double kidney cyst, moderate anemia, pleural effusion, hyperkalemia, pulmonary infection, and total heart failure. The patient was treated by the Qi-acupuncture therapy of TCM in combination with Chinese and Western medicine Medical treatment made the patient significantly better and discharged.

线粒体靶向治疗糖尿病肾病

线粒体在维持肾脏固有细胞正常功能中发挥了重要作用,糖尿病导致的高血糖状态,可引起线粒体稳态失衡和氧化应激反应,进而介导肾脏固有细胞损伤,参与糖尿病肾病的发生和发展。因此,靶向线粒体稳态失衡机制以及降低线粒体氧化损伤的小分子药物,有望为糖尿病肾病的治疗提供新的手段。本文将从靶向线粒体融合与分裂的干预、靶向线粒体生物发生的干预、靶向线粒体抗氧化剂及靶向线粒体自噬的干预等方面,综述近年来的最新研究进展。

5+2轻断食模式通过IRS1/PI3K/AKT通路激活自噬缓解2型糖尿病大鼠肾损伤

目的探究轻断食模式缓解2型糖尿病大鼠肾损伤的机制。方法将SD大鼠分为正常组、糖尿病组、轻断食+糖尿病组、MHY1485+轻断食+糖尿病组和740 Y-P+轻断食+糖尿病组,每组5只,除正常组外,其余各组均采用喂养高脂高糖饲料联合链脲佐霉素建立2型糖尿病大鼠模型。轻断食模式采用高脂高糖饲料喂食12 h禁食36 h的方法干预12 w,采用生化检测仪检测血清中肾功能指标。ELISA试剂盒检测大鼠空腹血清胰岛素(fasting serum insulin,FIN),并计算其胰岛素抵抗指数(HOMA-IR);qPCR检测IRS1、WT1、LC3B和P62的mRNA表达水平,Western Blot检测大鼠肾脏组织的IRS1、WT1、P62和LC3I/II蛋白的表达水平,研究IRS1/PI3K/AKT通路及自噬相关指标。取肾脏组织进行HE、PAS染色观察病理变化,采用免疫组化检测P62和LC3B的表达;最后采用Tunel染色评估肾脏组织凋亡情况。结果与正常组相比,糖尿病组的大鼠血清中血肌酐(serum creatinine,Scr)、尿素氮(blood urea nitrogen,BUN)、血脂甘油三酯(triglyceride,TG)、总胆固醇(total cholesterol,TCHO)、血清游离脂肪酸(free fatty acid,FFA)含量、空腹FINS、HOMA-IR均升高;而经轻断食模式后,上述指标含量均降低,与此同时qPCR和Western Blot结果显示,轻断食模式+糖尿病组相较于糖尿病组会下调IRS1表达,降低PI3K和AKT的磷酸化水平,从而影响LC3B表达上升,P62表达下降,使得肾脏组织的自噬活性提高,这与免疫组化的结果表现一致;病理染色证明轻断食使肾脏组织损伤减少,凋亡情况得到缓解,从WT1的上调也可看出足细胞损伤也到恢复。结论轻断食模式通过下调IRS1,抑制PI3K/AKT通路提高自噬活性,可缓解2型糖尿病大鼠肾损伤。缓解肾脏组织损伤对于延缓糖尿病肾病的发展有重要的意义。
