Abstract Background as one of the most important long term complications of diabetes, Diabetic nephropathy is the major cause of end stage renal disease and high mortality. Purpose to identify the pattern of microRNA-377 changes specific for diabetic nephropathy in diabetic patients and in patients with chronic kidney disease of different etiology. Patients and Methods the study was conducted from 2016 to 2018, included 50 patients for analysis of MicroRNA-377 and its control gene U18 at El Demrdash Hospital Ain shams university and Quessena Hospital El Monfia. The miRNA-U18 was analyzed for normalization of correction ratio. Results the results of our research found that the highest median IQR of miR-377 was significantly present in DN stage 1&2 and the lowest median IQR was significantly present in CKD stage 1&2, and there was significant difference between group 1 (DN stage 1&2) versus group 2 (DN stage 3&4), group 3 (Diabetics without nephropathy) and all stages of CKD. Conclusion in diabetic nephropathy stage 1&2, serum miR-377 was highly significant increased more than diabetics without nephropathy, diabetic nephropathy stage 3&4 and all satges of CKD.

Diabetic nephropathy (DN) is one of the most common complications of diabetes mellitus. After development of DN, patients will progress to end-stage renal disease, which is associated with high morbidity and mortality. Here, we developed early-stage diagnostic biomarkers to detect DN as a strategy for DN intervention. For the DN model, Zucker diabetic fatty rats were used for DN phenotyping. The results revealed that DN rats showed significantly increased blood glucose, blood urea nitrogen (BUN), and serum creatinine levels, accompanied by severe kidney injury, fibrosis and microstructural changes. In addition, DN rats showed significantly increased urinary excretion of kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL). Transcriptome analysis revealed that new DN biomarkers, such as complementary component 4b (C4b), complementary factor D (CFD), C-X-C motif chemokine receptor 6 (CXCR6), and leukemia inhibitory factor (LIF) were identified. Furthermore, they were found in the urine of patients with DN. Since these biomarkers were detected in the urine and kidney of DN rats and urine of diabetic patients, the selected markers could be used as early diagnosis biomarkers for chronic diabetic nephropathy.

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.

Background This study was conducted to evaluate the risk of developing acute pancreatitis (AP) and the fatality from AP in hemodialysis (HD) and peritoneal dialysis (PD) patients, using the claims data of Taiwan National Health Insurance. Methods From patients with newly diagnosed end-stage renal disease (ESRD) in 2000–2010, we identified a PD cohort ( N = 9,766), a HD cohort ( N = 18,841), and a control cohort ( N = 114,386) matched by sex, age, and the diagnosis year of the PD cohort. We also established another 2 cohorts with 9,744 PD patients and 9,744 propensity score-matched HD patients. The incident AP and fatality from AP were evaluated for all cohorts by the end of 2011. Results The adjusted hazard ratios (HRs) of acute pancreatitis were 5.68 (95% confidence interval [CI] = 5.05 – 6.39), 4.91 (95% CI = 4.32 – 5.59), and 7.47 (95% CI = 6.48 – 8.62) in the all dialysis, HD, and PD patients, compared with the controls, respectively. Peritoneal dialysis patients had an adjusted HR of 1.41 (95% CI = 1.21 – 1.65) for AP, compared with propensity score-matched HD patients. Peritoneal dialysis patients under icodextrin treatment had a lower incidence of AP than those without the treatment, with an adjusted HR of 0.59 (95% CI = 0.47 – 0.73). There was no significant difference in the 30-day mortality from AP between HD and PD patients. Conclusions Peritoneal dialysis patients were at a higher risk of developing AP than HD patients. Icodextrin solution could reduce the risk of developing AP in PD patients.

Background The aim of the study is to evaluate the long-term protective effect of N-acetylcysteine (NAC), an antioxidant agent, against aminoglycoside (AG)-induced ototoxicity. Methods A total of 40 patients receiving continuous ambulatory peritoneal dialysis (CAPD) and having their first peritonitis attacks and planned to be treated with AGs were enrolled in the study. They were randomized into 2 groups: 1 group received additional NAC and the other did not. All patients underwent hearing tests with pure tone audiometry (PTA) after the diagnosis, at 1 month and 12 months and at the same time the tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels were measured. Results Patients taking NAC had better hearing test results in both ears at 1 month except 2,000 Hz for the left ear, which wasn't significantly different between the 2 groups. Although patients taking NAC had generally better PTA results at 12 months, differences between the 2 groups were not statistically significant. Baseline IL-6 level was significantly higher in the NAC group than the control group. Both TNF-α and IL-6 levels at 1 month were significantly lower in the NAC group than in the control group. On the other hand, there was no significant difference between the 2 groups in terms of TNF-α and IL-6 levels at 12 months. Conclusions The results of the current study showed that NAC, a potent anti-inflamatory drug, may be otoprotective, but that the effect is not long-lasting.

The prevalence of diabetic nephropathy as a cause of end-stage renal disease [ESRD] in Egypt has been examined in small cross-sectional studies, with conflicting results. The need for a large-scale study prompted us to perform this 6-year multiple cross-sectional study. A sample of ESRD patients enrolled in the Egyptian renal data system was evaluated during the period 1996-2001 for the prevalence of diabetic nephropathy. Prevalence gradually increased from 8.9% in 1996, to 14.5% in 2001. The mean age of patients with diabetic nephropathy was significantly higher than that of patients with ESRD from other causes. Mortality was also significantly higher in diabetic patients with ESRD

BackgroundA significant proportion of anti-neutrophil cytoplasmic antibody (ANCA) associated glomerulonephritis eventually progresses to end-stage renal disease (ESRD) thus requiring long-term dialysis. There is no consensus about which dialysis modality is more recommended for those patients with associated vasculitis (AAV-ESRD). The primary objective of this study was to compare patient survival in patients with AAV-ESRD treated with hemodialysis (HD) or peritoneal dialysis (PD).MethodsThis double-center retrospective cohort study included dialysis-dependent patients who were treated with HD or PD. Clinical data were collected under standard format. The Birmingham vasculitis activity score (BVAS) was used to evaluate disease activity at diagnosis and organ damage was assessed using the vasculitis damage index (VDI) at dialysis initiation.ResultsIn total, 85 patients were included: 64 with hemodialysis and 21 with peritoneal dialysis. The patients with AAV-PD were much younger than the AAV-HD patients (48 vs. 62, P < 0.01) and more were female (76.2 vs. 51.6%, P = 0.05). The laboratory data were almost similar. The comorbidities, VDI score, and immuno-suppressive therapy at dialysis initiation were almost no statistical difference. Patient survival rates between HD and PD at 1 year were 65.3 vs. 90% (P = 0.062), 3 year were 59.6 vs. 90% (P < 0.001), and 5 years were 59.6 vs. 67.5% (P = 0.569). The overall survival was no significant difference between the two groups (P = 0.086) and the dialysis modality (HD or PD) was not shown to be an independent predictor for all-cause death (hazard ratio (HR) 0.73; 95% confidence interval (CI) 0.31–1.7; P = 0.473). Cardio-cerebrovascular events were the main cause of death among AAV-HD patients while infection in patients with AAV-PD.ConclusionThese results provide real-world data that the use of either hemodialysis or peritoneal dialysis modality does not affect patient survival for patients with AAV-ESRD who need long-term dialysis.

Изменения минерального гомеостаза являются причиной костных нарушений зубочелюстной системы (ЗЧС) при хронической болезни почек (ХБП) у детей и могут развиваться задолго до появления клинических проявлений уремической токсинемии на 2-й стадии ХБП. В последние годы большое внимание уделяется неинвазивным методам диагностики патологии полости рта у детей. Наиболее известными индикаторами нарушения костного метаболизма считают матриксную металлопротеиназу 8 (ММР-8) и остеопротогерин (OPG). Цель исследования - установить закономерности изменения содержания ММР-8 и OPG в слюне детей с различной тяжестью ХБП. Объект и методы. Проведено исследование содержания ММР-8 и OPG в слюне у 76 детей, которые были разделены на равные группы по 19 человек: 1 группа - дети с ХБП 1-2 степени, получающие медикаментозное лечение; 2 группа - дети с терминальной стадией ХБП, получающие заместительную почечную терапию в объёме гемодиализа; 3 группа - дети через год после перенесённой трансплантации почки; 4 группа (группа сравнения) - дети с малой хирургической патологией, не имеющие патологии почек. Сбор слюны осуществлялся абсорбционным методом до медикаментозной коррекции основного заболевания утром до приема пищи. Исследование ММР-8 и OPG проводили методом твердофазного иммуноферментного анализа. Результаты. Установлено, что содержание ММР-8 и OPG в слюне у детей с различной степенью ХБП было значительно выше по отношению к группе сравнения. Максимальные значения ММР-8 регистрировались во 2-й группе у детей с терминальной ХБП, находящихся на гемодиализе. Повышение содержания OPG в слюне отмечалось в 1 группе детей с ХБП 1-2-й степени и 3-й группе пациентов, через год после перенесённой трансплантации почки. Заключение. Полученные результаты показывают возможность использования слюны в качестве биологической жидкости для диагностики доклинических этапов нарушения костного метаболизма у детей с ХБП, а ММР-8 и OPG в слюне могут рассматриваться в качестве предиктивных и прогностических маркеров. Changes in mineral homeostasis cause bone disorders of the dentition in children with chronic kidney disease (CKD) and may develop long before the onset of clinical manifestations of uremic toxemia in stage 2 CKD. In recent years, much attention has been paid to noninvasive methods for diagnosing oral pathology in children. The most common indicators of metabolic bone disorders are matrix metalloproteinase-8 (MMP-8) and osteoprotogerin (OPG). The aim of the study was to establish the patterns of changes in salivary concentrations of MMP-8 and OPG in children with various severity of CKD. Subject and methods. Salivary levels of MMP-8 and OPG were studied in 76 children divided into four equal groups: group 1, children with stage 1-2 CKD receiving a drug treatment; group 2, children with end-stage CKD receiving renal replacement therapy with hemodialysis; group 3, children one year after the kidney transplantation; and group 4 (comparison group), children with a minor surgical pathology without a kidney pathology. Saliva samples were collected by the absorption method before administration of drugs for the underlying disease, one hour before the morning meal. Salivary concentrations of MMP-8 and OPG were measured by enzyme-linked immunosorbent assay. Results. Salivary levels of MMP-8 and OPG were significantly higher in children with various severity of CKD than in the comparison group. The highest values of MMP-8 were observed in group 2 children with end-stage CKD on hemodialysis. Increased salivary OPG was noted in group 1 children with stage 1-2 CKD and in group 3 patients one year after the kidney transplantation. Conclusion. Saliva can be used as a biological fluid for diagnosis of preclinical stages of bone metabolism disorders in children with CKD, and salivary MMP-8 and OPG can be considered as predictive and prognostic markers.

Diabetes prevalence is constantly increasing and, nowadays, it affects more than 350 million people worldwide. Therefore, the prevalence of diabetic nephropathy (DN) has also increased, becoming the main cause of end-stage renal disease (ESRD) in the developed world. DN is characterized by albuminuria, a decline in glomerular filtration rate (GFR), hypertension, mesangial matrix expansion, glomerular basement membrane thickening, and tubulointerstitial fibrosis. The therapeutic advances in the last years have been able to modify and delay the natural course of diabetic kidney disease (DKD). Nevertheless, there is still an urgent need to characterize the pathways that are involved in DN, identify risk biomarkers and prevent kidney failure in diabetic patients. Rodent models provide valuable information regarding how DN is set and its progression through time. Despite the utility of these models, kidney disease progression depends on the diabetes induction method and susceptibility to diabetes of each experimental strain. The classical DN murine models (Streptozotocin-induced, Akita, or obese type 2 models) do not develop all of the typical DN features. For this reason, many models have been crossed to a susceptible genetic background. Knockout and transgenic strains have also been created to generate more robust models. In this review, we will focus on the description of the new DN rodent models and, additionally, we will provide an overview of the available methods for renal phenotyping.

Inhibition of the RAAS (renin–angiotensin–aldosterone system) plays a pivotal role in the prevention and treatment of diabetic nephropathy and a spectrum of other proteinuric kidney diseases. Despite documented beneficial effects of RAAS inhibitors in diabetic patients with nephropathy, reversal of the progressive course of this disorder or at least long-term stabilization of renal function are often difficult to achieve, and many patients still progress to end-stage renal disease. Incomplete inhibition of the RAAS has been postulated as one of reasons for unsatisfactory therapeutic responses to RAAS inhibition in some patients. Inhibition of renin, a rate-limiting step in the RAAS activation cascade, could overcome at least some of the abovementioned problems associated with the treatment with traditional RAAS inhibitors. The present review focuses on experimental and clinical studies evaluating the two principal approaches to renin inhibition, namely direct renin inhibition with aliskiren and inhibition of the (pro)renin receptor. Moreover, the possibilities of renin inhibition and nephroprotection by interventions primarily aiming at non-RAAS targets, such as vitamin D, urocortins or inhibition of the succinate receptor GPR91 and cyclo-oxygenase-2, are also discussed.

Background: The number of coronary chronic total occlusion (CTO) patients with renal insufficiency is huge, and limited data are available on the impact of renal insufficiency on long-term clinical outcomes in CTO patients. We aimed to investigate clinical outcomes of CTO percutaneous coronary intervention (PCI) vs. medical therapy (MT) in CTO patients according to baseline renal function.Methods: In the study population of 2,497, 1,220 patients underwent CTO PCI and 1,277 patients received MT. Patients were divided into four groups based on renal function: group 1 [estimated glomerular filtration rate (eGFR) ≥ 90 ml/min/1.73 m2], group 2 (60 ≤ eGFR <90 ml/min/1.73 m2), group 3 (30 ≤ eGFR <60 ml/min/1.73 m2), and group 4 (eGFR <30 ml/min/1.73 m2). Major adverse cardiac event (MACE) was the primary end point.Results: Median follow-up was 2.6 years. With the decline in renal function, MACE (p < 0.001) and cardiac death (p < 0.001) were increased. In group 1 and group 2, MACE occurred less frequently in patients with CTO PCI, as compared to patients in the MT group (15.6% vs. 22.8%, p < 0.001; 15.6% vs. 26.5%, p < 0.001; respectively). However, there was no significant difference in terms of MACE between CTO PCI and MT in group 3 (21.1% vs. 28.7%, p = 0.211) and group 4 (28.6% vs. 50.0%, p = 0.289). MACE was significantly reduced for patients who received successful CTO PCI compared to patients with MT (16.7% vs. 22.8%, p = 0.006; 16.3% vs. 26.5%, p = 0.003, respectively) in group 1 and group 2. eGFR < 30 ml/min/1.73 m2, age, male gender, diabetes mellitus, heart failure, multivessel disease, and MT were identified as independent predictors for MACE in patients with CTOs.Conclusions: Renal impairment is associated with MACE in patients with CTOs. For treatment of CTO, compared with MT alone, CTO PCI may reduce the risk of MACE in patients without chronic kidney disease (CKD). However, reduced MACE from CTO PCI among patients with CKD was not observed. Similar beneficial effects were observed in patients without CKD who underwent successful CTO procedures.
