Background: Diabetic nephropathy (DN) often results in end-stage renal disease, and this is the most common reason for initiation of dialysis in the United States. Complications of diabetes, particularly renal disease, substantially increase the risk of subsequent severe illness and death. The prevalence of DN is still rising dramatically, with concomitant increases in associated mortality and cardiovascular complications. Summary: Renal involvement in type 1 and type 2 diabetes reflects a complex pathogenesis. Various genetic and environmental factors determine the susceptibility and progression to advanced stages of the disease. DN should be considered in patients who have had type 1 diabetes for at least 10 years with microalbuminuria and diabetic retinopathy, as well as in patients with type 1 or type 2 diabetes with macroalbuminuria in whom other causes for proteinuria are absent. The glomerular characteristic features include mesangial expansion, thickened glomerular basement membrane, and hyalinosis of arterioles. The optimal therapy of DN continues to evolve. For all diabetic patients, practical management including blood glucose and blood pressure control with renin-angiotensin-aldosterone blockade combined with lipid control, dietary salt restriction, lowering the dietary protein intake, increased physical activity, weight reduction, and smoking cessation can reduce the rate of progression of nephropathy and cardiovascular disease. Key Messages: DN is a complex disease linking hemodynamic and metabolic pathways with oxidative stress, and systemic inflammation. We summarize the current evidence of epidemiology, clinical diagnosis, and the current management of DN in Western countries. Facts from East and West: The prevalence of DN is increasing in Asia and Western countries alike. The deletion (D) allele of the angiotensin-converting enzyme gene is associated with progression to end-stage renal disease in Asian patients with DN, but this association is uncertain in Europeans. An association between DN and polymorphism of the gene coding for acetyl coenzyme A carboxylase β has been reported in Asian and Western populations. Both in Japan and the US, criteria for diagnosis are a 5-year history of diabetes and persistent albuminuria. Renal biopsy should be done in patients with severe hematuria, cellular casts and - in the US - hepatitis and HIV to rule out other pathologies. Diabetic retinopathy is considered a key criterion in Japan, but the absence of it does not rule out DN in the US. Enlargement of the kidney is observed as a diagnostic criterion in Japan. The differential use of renal biopsy as diagnostic tool might account for a different prevalence between Asian countries. Some Japanese diabetic patients show typical histological alterations for DN with a normal ACR and GFR. The clinical classification is similar between Japan and the US including five stages based on ACR and GFR. The Japanese guidelines do not include blood pressure values for the classification of DN. Guidelines for DN treatment are evolving quickly both in Asia and Western countries based on the numerous clinical trials performed worldwide. Targeting the angiotensin system for its hemodynamic and nonhemodynamic effects is a common approach. DPP-4 inhibitors are widely used in Japan and might have a higher glucose-lowering effect in Asian patients due to their specific diet. A randomized, double-blind placebo-controlled study has been launched to assess the efficacy of the Chinese herbal tea extract Shenyan Kangfu in DN.

Abstract Background Nephropathy, a major complication of diabetes, is the leading cause of end-stage renal disease. Early identification of nephropathy in diabetes patients is crucial because it creates opportunity for preventing the incidence of DN and/or even slows down the process of end-stage renal disease attributed to diabetes. Human podocytes (Pods) have been demonstrated to be functionally and structurally injured in the natural history of diabetic nephropathy. Aim of the Work To evaluate the possible association between the urinary podocalyxin levels and severity and grade of diabetic nephropathy and to use urinary podocalyxin as a non-invasive marker for early stage of diabetic nephropathy in type 2 DM. Patients and Methods We collected 60 known clinically and biochemically type 2 diabetic patients.20 diabetic patients with no evidence of diabetic nephropathy, 20 patients diagnosed as diabetic nephropathy in microalbuminuria stages and 20 patients diagnosed as diabetic nephropathy in macroalbuminuria stages from Ain Shams University hospitals between April and December 2018 and 20 apparently healthy volunteers will included as a control group. Results Urinary PCX was significantly higher in patients group compared to control group. Urinary PCX was significantly higher in microalbuminuric group than in normoalbuminuric group and higher in macroalbuminuric group than in microalbuminuric group. There was a positive significant correlation between FBS, 2HrPP, HBA1C and urinary PCX. There was a positive significant correlation between s.create and urinary PCX. There was a positive significant correlation between ACR and urinary PCX. Conclusion Urinary podocalyxin seems to be beneficial as an early marker for early stages of diabetic nephropathy in type 2 DM patients.

Abstract Background and Aims Systematic analysis of cardiac remodeling features in type 2 diabetic patients with end-stage renal disease (ESRD) is important both in stratification of cardiovascular risk and in choice of adequate treatment strategies. The lack of number and fragmentation of studies, the ambiguity of their data regarding the problem of myocardial reconstruction and cardiac valve calcification (CVC) under these conditions have substantiated the need for this study, its relevance and purpose. Method 136 ESRD patients on chronic hemodialysis (HD) were included in this observational cross-sectional study (men, 78; age, 53.9±1.0 years; HD duration, 47.6±4.2 months). The study was performed in accordance with the provisions of the Declaration of Helsinki last revision. Depending on the presence/absence of diabetic nephropathy (DN) all patients were divided into two groups: the 1st one – without DN (n=88); the 2nd one – with DN (n=48). A complete ultrasound examination of the cardiac structure and function including CVC analysis was performed. Data are presented as means±SEM. Mann-Whitney U-test was used for comparison of the quantitative variables, χ2-test – qualitative ones. Results Left ventricular (LV) hypertrophy (93.8 vs. 78.4%, р=0.020) and eccentric hypertrophy (47.9 vs. 28.4%, р=0.023) were diagnosed more often in patients with DN than those without diabetes. Prevalence of pseudonormal and restrictive types of LV diastolic dysfunction (62.5 vs. 28.4%, p<0.001), systolic dysfunction (27.1 vs. 9.1%, p=0.006) and pulmonary hypertension (PH) (64.6 vs. 35.2%, p=0.001) were significant in the 2nd group. CVC (66.6 vs. 38.6%, р=0.002), combined calcification of mitral (MV) and aortal (AV) valves (35.4 vs. 13.6%, p=0.003), stenoses of MV (16.7 vs. 3.4%, p=0.007) and AV (39.6 vs. 15.9%, p=0.004), and insufficiency of MV (66.7 vs. 44.3%, p=0.013) and AV (35.4 vs. 14.8%, p=0.006) were recorded more often in HD patients with DN. LV myocardial mass index (181.0±7.2 vs. 155.0±5.3 g/m2, p=0.001) as well as right ventricle (RV) diameter (2.80±0.09 vs. 2.47±0.04 cm, p=0.003) were also greater in the 2nd group. Conclusion In type 2 diabetic patients with ESRD occurs maladaptive cardiac remodeling with predominance of unfavourable (especially eccentric) types of LV hypertrophy, RV dilatation, PH, severe LV diastolic and systolic dysfunction, and widespread combined calcification of MV and AV with the valve defects. The identification of risk factors for the progression of the pathological reconstruction of myocardium and CVC in HD patients with DN will be the subject of our further research.

AbstractFew histological prognostic indicators for end-stage renal disease (ESRD) have been validated in diabetic patients. This biopsy-based study aimed to identify nephropathological risk factors for ESRD in Chinese patients with type 2 diabetes. Histological features of 322 Chinese type 2 diabetic patients with biopsy-confirmed diabetic nephropathy (DN) were retrospectively analysed. Cox proportional hazards analysis was used to estimate the hazard ratio (HR) for ESRD. Single glomerular proteomics and immunohistochemistry were used to identify differentially expressed proteins and enriched pathways in glomeruli. During the median follow-up period of 24 months, 144 (45%) patients progressed to ESRD. In multivariable models, the Renal Pathology Society classification failed to predict ESRD, although the solidified glomerulosclerosis (score 1: HR 1.65, 95% confidence interval [CI] 1.04–2.60; score 2: HR 2.48, 95% CI 1.40–4.37) and extracapillary hypercellularity (HR 2.68, 95% CI 1.55–4.62) were identified as independent risk factors. Additionally, single glomerular proteomics, combined with immunohistochemistry, revealed that complement C9 and apolipoprotein E were highly expressed in solidified glomerulosclerosis. Therefore, solidified glomerulosclerosis and extracapillary hypercellularity predict diabetic ESRD in Chinese patients. Single glomerular proteomics identified solidified glomerulosclerosis as a unique pathological change that may be associated with complement overactivation and abnormal lipid metabolism.

Objective: Although short adult height has been associated with an increasing variety of diseases and all-cause death, no reliable data exist on the association between adult height and end-stage renal disease (ESRD) in diabetic patients. We investigated the relationship between short adult height, development of ESRD, and mortality in type 2 diabetes mellitus (DM). Methods: This nationwide population-based cohort study analyzed clinical data from a total of 2,621,907 subjects aged ≥30 years with type 2 DM between January 1, 2009 and December 31, 2012, using the National Health Insurance Database in Korea. Results: During a 6.9-year follow-up period, 220,457 subjects (8.4%) died, and 28,704 subjects (1.1%) started dialysis. Short adult height significantly increased the incidence of ESRD and all-cause mortality in the overall cohort analysis. In multivariable Cox models, hazard ratios (HR) for the development of ESRD comparing the highest and lowest quartiles of adult height were 0.86 (95% CI 0.83–0.89). All-cause mortality also decreased with the highest height compared to patients with the lowest height, after fully adjusting for confounding variables (HR 0.79, 95% CI 0.78–0.81). Adult height had an inverse relationship to newly diagnosed ESRD (male: HR 0.86, 95% CI 0.83–0.90, female: HR 0.84, 95% CI 0.79–0.90) and all-cause mortality (male: HR 0.81, 95% CI 0.79–0.82, female: HR 0.80, 95% CI 0.78–0.82). Conclusions: Short adult height is strongly associated with the increased risk of ESRD development and all-cause mortality in type 2 DM.
