Understanding the Roles of Non-coding RNAs and Exosomal Non-Coding RNAs in Diabetic Nephropathy.

One of the greatest serious side effects of diabetes is diabetic nephropathy (DN), which is also the key factor in the sometimes-deadly diabetic end-stage renal disease. Progressive renal interstitial fibrosis is closely associated with oxidative stress, and the extracellular matrix is typically a feature of DN. Some RNAs formed by genome transcription that are not translated into proteins are recognized as noncoding RNAs. It has been shown that ncRNAs control apoptosis, inflammatory response, cell proliferation, autophagy, and other pathogenic processes, contributing to the pathogenesis of DN. Exosomes are nano-carriers vesicles that variety in size from 40 to 160 nm. Exosomes are widely present and dispersed in different bodily fluids, plentiful in nucleic acids, lipids, and proteins (microRNA, mRNA, tRNA, lncRNA, circRNA, etc.). Exosomes play a crucial role as messengers for cellular communication. They transport and transmit key signaling molecules, participate in the transfer of information and materials between cells, control cellular physiological processes, and are carefully linked to the beginning and development of many diseases. Herein, we summarized the role of different ncRNAs in DN. Moreover, we highlighted the role of the exosomal form of ncRNAs in the DN pathogenesis.

Microbiota analysis in individuals with type two diabetes mellitus and end‑stage renal disease: A pilot study.

Chronic kidney disease (CKD) is a widespread health concern, which affects ~9.1% of the global population and 12-15% of individuals in upper-middle income countries. Notably, ~2% of patients with CKD progress to end-stage renal disease (ESRD), which leads to a substantial decline in the quality of life, an increased risk of mortality and significant financial burden. Patients with ESRD often still suffer from uremia and uremic syndromes, due to the accumulation of toxins between dialysis sessions and the inadequate removal of protein-bound toxins during dialysis. A number of these toxins are produced by the gut microbiota through the fermentation of dietary proteins or cholines. Furthermore, the gut microbial community serves a key role in maintaining metabolic and immune equilibrium in individuals. The present study aimed to investigate the gut microbiota patterns in individuals with type 2 diabetes mellitus (T2DM) and ESRD via quantitative PCR analysis of the 16S and 18S ribosomal RNA of selected members of the gut microbiota. Individuals affected by both T2DM and ESRD displayed distinctive features within their intestinal microbiota. Specifically, there were increased levels of Gammaproteobacteria observed in these patients, and all subjects exhibited a notably increased presence of Enterobacteriaceae compared with healthy individuals. This particular microbial community has established connections with the presence of inflammatory processes in the colon. Moreover, the elevated levels of Enterobacteriaceae may serve as an indicator of an imbalance in the intestinal microbiota, a condition known as dysbiosis. In addition, the Betaproteobacteria phylum was significantly more prevalent in the stool samples of patients with both T2DM and ESRD when compared with the control group. In conclusion, the present pilot study focused on gut microbiome alterations in T2DM and ESRD. Understanding the relationship between dysbiosis and CKD may identify new areas of research and therapeutic interventions aimed at modulating the gut microbiota to improve the health and outcomes of individuals with CKD and ESRD.

Status and trends in epidemiologic characteristics of diabetic end-stage renal disease: an analysis of the 2021 Korean Renal Data System.

Korean Renal Data System (KORDS) is a nationwide end-stage renal disease (ESRD) registry database operated by the Korean Society of Nephrology (KSN). Diabetes mellitus is currently the leading cause of ESRD in Korea; this article provides an update on the trends and characteristics of diabetic ESRD patients. The KORDS Committee of KSN collects data on dialysis centers and patients through an online registry program. Here, we analyzed the status and trends in characteristics of diabetic chronic kidney disease stage 5D (CKD 5D) patients using data from 2001 to 2021. In 2021, the dialysis adequacy of hemodialysis (HD) was lower in diabetic CKD 5D patients than in nondiabetic CKD 5D patients, while that of peritoneal dialysis (PD) was similar. Diabetic CKD 5D patients had a higher proportion of cardiac and vascular diseases and were more frequently admitted to hospitals than nondiabetic CKD 5D patients, and the leading cause of death was cardiac disease. From 2001 to 2020, diabetic CKD 5D patients had a higher mortality rate than nondiabetic CKD 5D patients, but in 2021 this trend was reversed. Diabetic PD patients had the highest mortality rate over 20 years. The mortality rate of diabetic HD patients was higher than that of nondiabetic HD patients until 2019 but became lower starting in 2020. There was a decreasing trend in mortality rate in diabetic CKD 5D patients, but cardiac and vascular diseases were still prevalent in diabetic CKD 5D patients with frequent admissions to hospitals. More specialized care is needed to improve the clinical outcomes of diabetic CKD 5D patients.

Impact of initial dialysis modality on the survival of patients with ESRD: a propensity-score-matched study

BackgroundStudies comparing the survival of hemodialysis (HD) and peritoneal dialysis (PD) patients are controversial. This study evaluated the impact of initial dialysis modality on the survival of patients with end-stage renal disease (ESRD) in a matched-pair cohort.MethodsA retrospective cohort study was performed on ESRD patients who initiated renal replacement treatment between January 1, 2010, and December 31, 2018. Propensity score matching was applied to balance the baseline conditions, and multivariate Cox regression analysis was applied to compare mortality between HD and PD patients and evaluate correlations between mortality and various baseline characteristics. Subgroup analysis was performed with respect to diabetes status.ResultsThere were 739 patients in our center in the Chinese National Renal Data System (CNRDS) between 2010 and 2018. Of these, 125 PD patients were matched with 125 HD patients. The 1-, 2-, and 3-year survival rates were 96.5%, 90.7%, and 82.5%, respectively, in the HD group and 99.5%, 97.8%, and 92.5%, respectively, in the PD group (log-rank P < 0.001). Among the propensity score-matched cohorts, no significant differences in Kaplan–Meier curves were observed between the two groups (log-rank P = 0.514). Age at dialysis initiation, CCI, congestive heart failure and cerebrovascular disease were risk factors in the multivariable-adjusted model. In subgroups defined by diabetes status, the Kaplan‒Meier survival curve showed that PD survival was significantly higher than that of HD (log-rank P = 0.022).ConclusionsHD and PD were not significantly different regarding the survival of patients with ESRD. PD was associated with better survival in diabetic ESRD patients.

Influence of dialysis-related stigma on health-related indicators in Japanese patients undergoing hemodialysis.

Focusing on impacts to health-related indicators in older Japanese patients, this study analyzed both the direct influence of dialysis-related stigma and influences of its intersectionality with other stigmatized characteristics. Data were collected through a cross-sectional survey of 7461 outpatients in dialysis facilities. Other stigmatized characteristics include lower income, lower education, disabled activities of daily living, and diabetic end-stage renal disease (ESRD) as a cause for starting dialysis treatment. The average rate of an "agree" response on dialysis-related stigma items was 18.2%. Dialysis-related stigma significantly influenced all three health-related indicators, including suspected depression, informal networks, and compliance with dietary therapy. In addition, each interaction between dialysis-related stigma and educational attainment, gender, and diabetic ESRD significantly influence one health-related indicator. These results suggest that dialysis-related stigma has both a significant direct and synergic influence with other stigmatized characteristics on health-related indicators.

Blood pressure status affects atrial fibrillation in diabetic end-stage renal disease.

The prevalence of atrial fibrillation (AF) is increasing as the elderly population continues to increase. Chronic kidney disease, diabetes, and hypertension are known risk factors for AF. Since multimorbidity exists in chronic kidney disease, it is difficult to determine the impact of hypertension alone. Furthermore, little is known about the impact of hypertension on predicting AF in diabetic end-stage renal disease (ESRD). Here, we evaluated the effect of differential blood pressure control on AF prevalence among the diabetic ESRD population. From the Korean National Health Insurance Service database, 2 717 072 individuals with diabetes underwent health examinations during 2005-2019. Exactly 13 859 individuals with diabetic ESRD without a prior history of AF were selected and included in the analysis. Based on blood pressure level and previous hypertension medication history, we subdivided them into five groups: normal (normotensive), pre-hypertension, new onset hypertension, controlled hypertension, and uncontrolled hypertension. AF risk according to the blood pressure groups was estimated using Cox proportional-hazards models. Among the five groups, the new onset hypertension, controlled hypertension, and uncontrolled hypertension groups showed a higher AF risk. In patients on antihypertensives, diastolic blood pressure ≥100 mmHg was significantly associated with AF risk. High pulse pressure showed a significant risk for AF in patients on antihypertensives. In patients with diabetic ESRD, overt hypertension and a history of hypertension impacts AF. AF risk was higher in the ESRD population with diastolic blood pressure ≥100 mmHg and pulse pressure >60 mmHg.

End-stage renal disease incidence in a cohort of US firefighters from San Francisco, Chicago, and Philadelphia.

Firefighters perform strenuous work in hot environments, which may increase their risk of chronic kidney disease. The purpose of this study was to evaluate the risk of end-stage renal disease (ESRD) and types of ESRD among a cohort of US firefighters compared to the US general population, and to examine exposure-response relationships. ESRD from 1977 through 2014 was identified through linkage with Medicare data. ESRD incidence in the cohort compared to the US population was evaluated using life table analyses. Associations of all ESRD, systemic ESRD, hypertensive ESRD, and diabetic ESRD with exposure surrogates (exposed days, fire runs, and fire hours) were examined in Cox proportional hazards models adjusted for attained age (the time scale), race, birth date, fire department, and employment duration. The incidence of all ESRD was less than expected (standardized incidence ratio (SIR) = 0.79; 95% confidence interval = 0.69-0.89, observed = 247). SIRs for ESRD types were not significantly increased. Positive associations of all ESRD, systemic ESRD, and hypertensive ESRD with exposed days were observed: however, 95% confidence intervals included one. We found little evidence of increased risk of ESRD among this cohort of firefighters. Limitations included the inability to evaluate exposure-response relationships for some ESRD types due to small observed numbers, the limitations of the surrogates of exposure, and the lack of information on more sensitive outcome measures for potential kidney effects.

Comparison of Hearing Abnormalities in Non-Diabetic and Diabetic End-Stage Renal Disease Patients Undergoing Hemodialysis

Background and Aim: Hearing loss is a highly prevalent symptom in patients with chronic kidney diseases (CKD). Comorbidities such as Diabetes Mellitus is known as the most common cause of CKD and a significant risk factor for sensorineural hearing loss (SNHL). The aim of this study was to compare SNHL among diabetic with non-diabetic hemodialysis patients.&#x0D; Methods: In this study, 33 diabetic patients on hemodialysis were selected from Hami center, Arak, Iran. Non-diabetic subjects were 31 hemodialysis patients without diabetes were matched for age, duration of CKD and hemodialysis. Data were obtained via questionnaire, patients’ files, physical examination, otoscopy and tympanometry. Hearing was analyzed using pure-tone audiometry for both groups.&#x0D; Results: In the study, 66.2% of diabetic patients and 52.1% of non-diabetic subjects had SNHL. Results showed that diabetic patient has 1.3 times more likely to have hearing impairment. This difference was not statistically significant. Bilateral mild SNHL was the most prevalent in both groups. No significant difference was reported in SNHL prevalence, mean thresholds of hearing and ear laterality between the groups. Gender and age had a significant effect on hearing loss after adjusting covariables. No significant association was found between diabetes and hearing loss.&#x0D; Conclusion: SNHL was more common in hemodialysis patients with diabetes. Patients with diabetes had poorer hearing thresholds compared to non-diabetic group, with no significant difference between groups. The periodical assessment of hearing and extending audiological care in this high-risk population is recommended due to long-term irreversible symptoms of the disease.&#x0D; Keywords: Diabetes mellitus; hearing loss; end-stage renal disease

Diabetes Prediction Model Comparison between XgBoost and SVM Algorithms

Diabetes is a global health epidemic. It increases the danger of cardiovascular disease by fourfold in women and around twice in men. ‘Diabetes’ is an umbrella term for a number of different subtypes of the disease. The most common are Type 1 Diabetes Mellitus (T1DM) and Type 2 Diabetes Mellitus (T2DM). Compared to men, women are also at a greater risk of retinopathy and neuropathy from diabetes. Pregnancy may worsen pre-existing conditions and lead to significant blindness. It also aggravates pre-existing kidney diseases. Elderly women with type 2 diabetes mellitus (T2DM) and end-stage renal disease have a significantly higher risk of death than men with similar diseases. Women with diabetes have higher chances of suffering a stroke in comparison to women without it. Women are also more likely to develop depression compared to men. The modeling of support vector machines may additionally be a promising classification technique for identifying women among the population with common diseases like polygenic disorder and pre-diabetes. We use different algorithms for classification, XGBoost based on SVM with GridSearchCV predict results with 83.5% accuracy.

Effect of Glomerular Filtration Rate by Different Equations on Prediction Models for End-Stage Renal Disease in Diabetes.

Background and ObjectivesThe study aimed to evaluate the performance of a predictive model using the kidney failure risk equation (KFRE) for end-stage renal disease (ESRD) in diabetes and to investigate the impact of glomerular filtration rate (GFR) as estimated by different equations on the performance of the KFRE model in diabetes.Design, Setting, Participants, and MeasurementsA total of 18,928 individuals with diabetes without ESRD history from the UK Biobank, a prospective cohort study initiated in 2006–2010, were included in this study. Modification of diet in renal disease (MDRD), chronic kidney disease epidemiology collaboration (CKD-EPI) or revised Lund–Malmö (r-LM) were used to estimate GFR in the KFRE model. Cox proportional risk regression was used to determine the correlation coefficients between each variable and ESRD risk in each model. Harrell’s C-index and net reclassification improvement (NRI) index were used to evaluate the differentiation of the models. Analysis was repeated in subgroups based on albuminuria and hemoglobin A1C (HbA1c) levels.ResultsOverall, 132 of the 18,928 patients developed ESRD after a median follow-up of 12 years. The Harrell’s C-index based on GFR estimated by CKD-EPI, MDRD, and r-LM was 0.914 (95% CI = 0.8812–0.9459), 0.908 (95% CI = 0.8727–0.9423), and 0.917 (95% CI = 0.8837–0.9496), respectively. Subgroup analysis revealed that in diabetic patients with macroalbuminuria, the KFRE model based on GFR estimated by r-LM (KFRE-eGFRr-LM) had better differentiation compared to the KFRE model based on GFR estimated by CKD-EPI (KFRE-eGFRCKD-EPI) with a KFRE-eGFRr-LM C-index of 0.846 (95% CI = 0.797–0.894, p = 0.025), while the KFRE model based on GFR estimated by MDRD (KFRE-eGFRMDRD) showed no significant difference compared to the KFRE-eGFRCKD-EPI (KFRE-eGFRMDRD C-index of 0.837, 95% CI = 0.785–0.889, p = 0.765). Subgroup analysis of poor glycemic control (HbA1c >8.5%) demonstrated the same trend. Compared to KFRE-eGFRCKD-EPI (C-index = 0.925, 95% CI = 0.874–0.976), KFRE-eGFRr-LM had a C-index of 0.935 (95% CI = 0.888–0.982, p = 0.071), and KFRE-eGFRMDRD had a C-index of 0.925 (95% CI = 0.874–0.976, p = 0.498).ConclusionsIn adults with diabetes, the r-LM equation performs better than the CKD-EPI and MDRD equations in the KFRE model for predicting ESRD, especially for those with macroalbuminuria and poor glycemic control (HbA1c >8.5%).

The relationship between B-cell lymphoma 2, interleukin-1β, interleukin-17, and interleukin-33 and the development of diabetic nephropathy

Diabetic nephropathy (DN) is among the main complications of diabetes mellitus and has been a major factor of renal failure. This study was designed to address the association between beta-cell lymphoma-2 (Bcl-2), interleukin (IL)-1β, IL-17, and IL-33 and the development of DN. In this study, 20 healthy volunteers and 100 patients were enrolled. According to their biochemical markers, the patients were categorized into five groups: diabetic, chronic renal disease, diabetic chronic renal disease, end-stage renal disease, and diabetic end-stage renal disease. Our results showed a noticeable elevation in IL-1β and IL-17 levels and a reduction in IL-33 and Bcl-2 levels in all investigated groups compared with those in the healthy group. Positive correlations were found between IL-1β and fasting blood sugar and between creatinine levels and IL-17, HbA1c%, and sodium levels. However, negative correlations were found between IL-33 and urea and sodium concentrations and between Bcl-2 and HbA1c% and creatinine levels. The present data revealed a marked relationship between Bcl-2, IL-1β, IL-17, and IL-33 levels and the onset and progression of DN. Understanding the molecular pathways of these processes could be translated into the development of therapeutic strategies.

MO641IMPACT OF MAGNESIUM AND L-CARNITINE ADMINISTRATION ON 3-YEAR SURVIVAL IN DIABETIC PATIENTS WITH END-STAGE RENAL DISEASE

Abstract Background and Aims According to population registries, the survival of diabetic patients with end-stage-renal disease (ESRD) remains low today. In this context, it is reasonable to develop new therapeutic strategies based on advances in science of the important role of magnesium (Mg) and L-carnitine deficiency (via inflammation and endothelial dysfunction) in mechanisms of cardiovascular remodeling, high morbidity and mortality rates. Thus, the purpose of the present study was to evaluate the effect of Mg and L-carnitine supplementation on 3-year survival and development of the cardiovascular complications in diabetic hemodialysis (HD) patients. Method 48 type 2 diabetic ESRD patients were included in this prospective cohort study (male/female, 29/19; age, 59.9±0.6 years; HD duration, 34.8±4.8 month; diabetes mellitus duration, 174.7±7.1 month). The study was performed in accordance with the provisions of the Declaration of Helsinki last revision. Depending on the treatment programme, patients were divided into two groups: the 1st (main) group (n=24) in addition to basic treatment (hypoglycemic, antihypertensive therapy, according to indications - correction of anemia, hyperparathyroidism, hyperphosphatemia) was treated by combination of magnesium aspartate (0.5 g/day orally) and L-carnitine (1 g/day parenterally after each HD session (three times weekly); the 2nd (comparison) group (n=24) was only on the basic therapy. Complex treatment lasted 12-months; administration of L-carnitine was performed continuously throughout the year, while magnesium aspartate – by three 2-months’ courses/year. The follow up period in both groups was 36 months. Quantitative data are expressed as means±SEM, qualitative ones – as %. Kaplan-Meier method and Log-rank test were used to estimate survival of HD patients, χ2-test – to compare the frequency values. Results The cumulative proportion of survivors at the end of follow-up was 60.4%; however, after 36 months, the survival rate of diabetic HD patients who received a combination of magnesium aspartate and L-carnitine as part of their modified treatment was significantly higher (75 vs. 45.8%; Log-rank=2.07, p=0.038) compared to patients who were on basic therapy (Figure). Survival time in main and comparison groups was 31.9±1.7 and 26.4±2.2 months respectively. It is noteworthy, that throughout the year (from 10 to 22 months), no completed events were recorded in subjects who underwent Mg and L-carnitine supplementation. Conclusion (1) The combined use of magnesium aspartate and L-carnitine in addition to the basic 12-month treatment provides an effective reduction of cardiovascular complications and promotes 3-year survival of diabetic HD patients. (2) The results obtained substantiate the advisability of using repeated courses of Mg and L-carnitine administration 1 years after the end of the primary modified treatment to improve the prognosis in these ESRD patients.

The Role of Non-coding RNAs in Diabetic Nephropathy-Related Oxidative Stress.

Diabetic nephropathy (DN) is one of the main complications of diabetes and the main cause of diabetic end-stage renal disease, which is often fatal. DN is usually characterized by progressive renal interstitial fibrosis, which is closely related to the excessive accumulation of extracellular matrix and oxidative stress. Non-coding RNAs (ncRNAs) are RNA molecules expressed in eukaryotic cells that are not translated into proteins. They are widely involved in the regulation of biological processes, such as, chromatin remodeling, transcription, post-transcriptional modification, and signal transduction. Recent studies have shown that ncRNAs play an important role in the occurrence and development of DN and participate in the regulation of oxidative stress in DN. This review clarifies the functions and mechanisms of ncRNAs in DN-related oxidative stress, providing valuable insights into the prevention, early diagnosis, and molecular therapeutic targets of DN.

Solidified glomerulosclerosis, identified using single glomerular proteomics, predicts end-stage renal disease in Chinese patients with type 2 diabetes

Few 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.

Comorbidity Profiles among Obese–Diabetic End-Stage Renal Disease Patients: Data from REIN Registry of PACA Region of France

IntroductionThe proportion of new dialysis patients with comorbidities increased by an average of 5.6% per year in the Provence-Alpes-Côte d’Azur (PACA) region, with major increases in obese, cancer, and diabetic patients. This study aimed to describe comorbidity profiles among obese–diabetic end-stage renal disease (ESRD) patients in the Renal Epidemiology and Information Network (REIN) registry of the PACA region of France on December 31, 2018.MethodsData for this retrospective cross-sectional study were retrieved from the REIN registry of the PACA region. Data were analyzed using two models. Firstly, the ESRD patients were divided into two groups and binary logistic regression model used for the analysis of the data. Secondly, ESRD patients were divided into four groups and multinomial logistic regression model used. Univariate analysis was performed for group comparison using x2 and t-tests, while binary logistic and multinomial logistic regression models were used for multivariate analysis to derive ORs and 95% CIs.ResultsAmong the 4,491 ESRD patients in this study, 623 were obese–diabetic and 3,868 nonobese–nondiabetic and obese only/ diabetic only. Obese–diabetic ESRD patients were younger (<75 years, OR 0.46, p<0.001), smoked less (OR 0.51, p<0.001), were mainly dialyzed at centers (OR 1.29, p=0.014), and less likely to be on the renal transplant waiting list (OR 0.46, p<0.001) compared to the other group. Obese–diabetic ESRD patients also had more comorbidities, including cardiovascular diseases (OR 1.38, p=0.028), coronary insufficiency (OR 1.49, p=0.001) and chronic obstructive pulmonary disease (OR 1.75, p<0.001), but had fewer cases of cancer (OR 0.68, p=0.024) compare to the other group.ConclusionObese–diabetic patients with ESRD have many specific characteristics. These patients were younger, but had more cardiovascular comorbidities and were less likely to be on the waiting list for transplantation. They should receive special attention and be the subject of prevention and therapeutic education.

Non-traditional Risk Factors of Cardiovascular Disease and Coenzyme Q10 Therapy in Hemodialysis Patients

Background: Inflammatory markers increase in end-stage renal disease (ESRD), especially in diabetic patients, and are positively correlated with cardiovascular mortality. Coenzyme Q10 (CoQ10), an agent with antioxidant properties, may be effective in reducing cardiovascular complications in hemodialysis patients. This study aimed to investigate the effects of CoQ10 supplementation on plasma C-reactive protein (CRP), homocysteine, and albumin in hemodialysis patients. Methods: Forty diabetic ESRD patients on hemodialysis for at least six months were evaluated in a double-blinded randomized clinical trial. The patients were randomly assigned to one of the two groups to receive either CoQ10 100 mg daily or placebo. In all patients, the serum levels of homocysteine, albumin, and CRP were measured before and after six months. Results: The mean age of the patients was 60.3 ± 9.1 years, and 57.5% of the participants were female. There was no statistical difference between the two groups at baseline. Furthermore, no significant difference was observed in serum albumin (P = 0.843), CRP (P = 0.214), and homocysteine (P = 0.21) at the end of the intervention between the groups. Conclusions: This study showed that in patients with ESRD, using CoQ10 supplementation has minimal beneficial effects on serum albumin, CRP, and homocysteine levels.

Диабетическая нефропатия: о чем должен помнить кардиолог

Prevalence of diabetes mellitus (DM) progressively increases around the world. Diabetic nephropathy (DN) is significant reason of end-stage renal disease and it is associated with high risk of cardiovascular disease and mortality. Necessity of expensive renal replacement therapy for patients with prominent vascular diabetic complications and end-stage renal disease has significant socio-economic impact. DM, as a one of leading causes of kidney diseases, competes for stricted resources of public health. Renal replacement therapy in patients with DM does not solve the whole problem, because survival of such patients is low, comparing with another kidney diseases, first of all because of cardiovascular diseases. Good control of glycaemia, blood pressure and cholesterol level and prescription of renin-angiotensin-aldosterone system inhibitors and statins decrease cardiovascular risk and slow down DN progression, as it was shown in many clinical trials. So patients with DM and DN should receive complex therapy for risk reduction of kidney disease and cardiovascular disorders progression.

A Retrospective Analysis of Microbiologic Profile of Foot Infections in Patients With Diabetic End-Stage Renal Disease.

Individuals with diabetes and end-stage renal disease (ESRD) are at increased risk of foot ulceration and lower extremity amputation. Although risk factors and microbiologic analysis of diabetic foot infections (DFIs) have been extensively studied, there are limited data available for this characteristic group. Clinical, demographic, laboratory, microbiological data, and foot examination information were collected retrospectively regarding 94 patients with ESRD who were referred for DFI between 2006 and 2016 to hyperbaric oxygen therapy. In 6 of 94 patients with ESRD (mean age 60 years; 65 males [69.1%], 29 women [30.8%]; 91 undergoing hemodialysis [96.8%], one peritoneal dialysis [1%], two [2%] recent renal transplants), the lesions were bilateral; therefore, the evaluations were made over 100 DFIs. The most common pathogens isolated in deep wound cultures were Staphylococcus aureus and Pseudomonas aeruginosa, respectively, contributing to 27 (21.2%) and 16 (12.5%) of all 127 isolates. When the distribution of the isolates according to different Wagner grades were analyzed, it was found that the proportion of Gramnegative isolates increased statistically significantly with the ascending Wagner grade (P = .004). DFIs indicate a serious complication associated with a high risk of amputation, prolonged antibiotic treatment, increased hospital and procedure demands, and the cost of health care, on patients with ESRD. The familiarization of causative pathogens underlying DFIs can aid the clinicians in the choice of appropriate empirical antibiotic treatment. This study emphasizes the need for greater attention to risk factors and the microbiologic profile of DFIs in this characteristic group.

Curcumin Help Arteriovenous Fistula Maturation

Curcumin has many advantages, i.e., antioxidant, antiplatelet, anti-inflammatory, and antidiabetes. It applied for the maturation of arteriovenous fistula (AVF) in the diabetic end-stage renal disease of two diabetic patients. The administration of oral Curcumin examined the maturation on the 4th week and the 8th week. The results in both cases show maturity at the end of eight weeks without any complication.

Should Pre-Transplant Hemoglobin A1c Be Used to Predict Post-Transplant Compliance in End-Stage Renal Disease Patients Undergoing Kidney Transplantation?

BackgroundPatient compliance with immunosuppressive therapy after transplant has impacts on both graft and patient outcomes. For diabetic end-stage renal disease (ESRD) patients who are undergoing evaluation for kidney transplantation in our program, hemoglobin A1c (HbA1c) level of >10% is used as a flag that the patient may be at risk for noncompliance and that more comprehensive psychosocial screening is needed prior to transplant. We evaluated the association between pre-transplant HbA1c level and post-transplant compliance, as no study to date has looked at this in the transplant population.Material/MethodsThe charts of 392 patients who received a kidney transplant at a single institution between July 2008 and June 2012 were retrospectively reviewed. One hundred and sixty-five diabetic patients who received a kidney transplant alone were included in the final analysis. Our predictive variable was HbA1c level greater than 7.7% based on previous reports in the diabetic population. Outcome measures were graft survival, rejection episodes, unexplained low immunosuppressant levels, and documented noncompliance.ResultsThere were no statistically significant differences between the HbA1c groups of ≤7.7% and >7.7% in outcomes of failed grafts (22.0% and 17.8%, p=0.2), rejection episodes (15.0% and 6.7%, p=0.3), unexplained low immunosuppressant level (46.6% and 37.9%, p=0.3), and documented noncompliance (25.0% and 16.7%, p=0.4).ConclusionsIn diabetic ESRD patients selected for renal transplantation, elevated pre-transplant HbA1c levels, defined as HbA1c >7.7%, are not predictive of post-transplant medication compliance. We advocate that this group of patients should not be denied transplant solely on their elevated pre-transplant HbA1c.
