Abstract Background Literature on recovery of kidney function (RKF) in patients with end-stage kidney disease treated with maintenance dialysis (i.e. over 90 days) is limited. We assessed the incidence of RKF and its associated characteristics in a European cohort of dialysis patients. Methods We included adult patients from the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry who started maintenance dialysis in 1997-2016. Sustained RKF was defined as permanent discontinuation of dialysis. Temporary discontinuation of ≥ 30 days (non-sustained RKF) was also evaluated. Factors associated with RKF adjusted for potential confounders were studied using Cox-regression analyses. Results RKF occurred in 7,657 (1.8%) of 440,996 patients of whom 71% experienced sustained RKF. Approximately 90% of all recoveries occurred within the first two years after day 91 of dialysis. Of patients with non-sustained RKF, 39% restarted kidney replacement therapy within one year. Sustained RKF was strongly associated with the following underlying kidney diseases (as registered by the treating physician): tubular necrosis (irreversible) or cortical necrosis (adjusted Hazard Ratio [aHR]: 20.4, 95%CI: 17.9-23.1), systemic sclerosis (aHR: 18.5, 95%CI: 13.8-24.7) and hemolytic uremic syndrome (aHR: 17.3, 95%CI: 13.9-21.6). Weaker associations were found for hemodialysis as first dialysis-modality (aHR: 1.5, 95%CI: 1.4-1.6) and dialysis initiation at an older age (aHR: 1.8, 95%CI: 1.6-2.0) or in a more recent time-period (aHR: 2.4, 95%CI: 2.1-2.7). Conclusions Definitive discontinuation of maintenance dialysis is a rare and not necessarily an early event. Certain clinical characteristics, but mostly the type of underlying kidney disease, are associated with a higher likelihood of RKF.

Background: Our aim was to study the association between the country of birth and incident end-stage kidney disease (ESKD) in several immigrant groups in Sweden, using individuals born in Sweden or with Swedish-born parents as referents. Methods: A cohort study of first- and second-generation immigrants residing in Sweden between January 1, 1998 and December 31, 2012 was performed. Outcomes were defined as having at least one registered diagnosis of ESKD in the National Patient Register. The incidence of ESKD in different immigrant groups was used in the Cox regression models to estimate hazard ratios (HRs) and 95% CIs. All models were stratified by sex and adjusted for age, geographical residence, educational level, marital status, and neighbourhood socioeconomic status. Results: Compared to their referents, higher incidence rates and HRs of ESKD (HR; 95% CI) were observed in general among foreign-born men (1.10; 1.04–1.16) and women (1.12; 1.04–1.21) but not among second-generation immigrants (persons born in Sweden with foreign-born parents). A particularly high ­incidence was noted among men and women from ­East-European countries, as well as from non-European regions. A lower incidence of ESKD was noted among men from Finland. Conclusions: We observed substantial differences in incidence of ESKD between immigrant groups and the Swedish-born population, which may be clinically relevant when monitoring preventive measures in patient subgroups with a higher risk of deteriorating kidney disease, and suggest higher attention to hypertension and diabetes control in immigrants. Mechanisms attributable to the migration process or ethnic differences may lead to an increased risk of ESKD.

Chronic kidney disease (CKD) affects 10–15% of the population worldwide and its prevalence is increasing. Objective: To find the frequency of common diseases causing chronic kidney diseases (CKD) in dialysis dependent patients in District Swat, Khyber Pukhtonkhwa. Methodology: Cross sectional study at Department of Nephrology Nawaz Sharif Kidney Hospital, District Swat, Khyber Pukhtonkhwa, Pakistan. Results: Total of 110 patients were undergoing maintenance hemodialysis. There were 53(48.2%) male and mean age was 54.40+ 16.32 years. Among 110 patients, only 9 (8.2%) had dialysis once per week and 101(91.8%) had dialysis twice per week hemodialysis. Majority, 64(58.2%) patients were undergoing dialysis less than one year. 6(5.5 %) had hypertension, 33(30%) had diabetes and 68(61.8%) patients had both Diabetes and Hypertension. Out of 110, 39(35.5%) patients were Hepatitis B positive, and 28(25.5%) patients had Hepatitis C. Conclusion:  Results of this study showed that the leading cause of chronic kidney disease (CKD) among dialysis patients was diabetes mellitus with or without hypertension and a high prevalence of both HBV and HCV.

AbstractThe prognostic significance of suPAR in various kidney diseases has recently been demonstrated. Its role in transplantation-specific outcomes is still largely unknown. Therefore, we prospectively investigated the prognostic relevance of suPAR in patients before and one year after kidney transplantation (KTx). We included 100 patients who had received a kidney transplantation between 2013 and 2015. The plasma concentration of suPAR was measured by ELISA assay. In recipients of living donations (LD), pre-transplant suPAR levels were significantly lower than those of recipients of deceased donations (DD). After KTx, suPAR levels significantly declined in LD and DD recipients, without a detectable difference between both groups any more. Higher suPAR levels in recipients one year after KTx were associated with a more severe eGFR loss in the following three years in multivariable cox-regression (n = 82, p = 0.021). suPAR-levels above 6212 pg/ml one year after KTx are associated with eGFR loss > 30%, which occurred almost twice as fast as in patients with suPAR ≤ 6212 pg/ml (p < 0.001). Hence, suPAR level at one year mark might be a risk indicator of increased eGFR loss.

The retention of uremic toxins and their pathological effects occurs in the advanced phases of chronic kidney disease (CKD), mainly in stage 5, when the implementation of conventional thrice-weekly hemodialysis is the prevalent and life-saving treatment. However, the start of hemodialysis is associated with both an acceleration of the loss of residual kidney function (RKF) and the shift to an increased intake of proteins, which are precursors of uremic toxins. In this phase, hemodialysis treatment is the only way to remove toxins from the body, but it can be largely inefficient in the case of high molecular weight and/or protein-bound molecules. Instead, even very low levels of RKF are crucial for uremic toxins excretion, which in most cases are protein-derived waste products generated by the intestinal microbiota. Protection of RKF can be obtained even in patients with end-stage kidney disease (ESKD) by a gradual and soft shift to kidney replacement therapy (KRT), for example by combining a once-a-week hemodialysis program with a low or very low-protein diet on the extra-dialysis days. This approach could represent a tailored strategy aimed at limiting the retention of both inorganic and organic toxins. In this paper, we discuss the combination of upstream (i.e., reduced production) and downstream (i.e., increased removal) strategies to reduce the concentration of uremic toxins in patients with ESKD during the transition phase from pure conservative management to full hemodialysis treatment.

Abstract Inherited kidney diseases (IKDs) are among the leading causes of early-onset chronic kidney disease (CKD) and are responsible for at least 10–15% of cases of kidney replacement therapy (KRT) in adults. Pediatric nephrologists are very aware of the high prevalence of IKDs among their patients, but this is not the case for adult nephrologists. Recent publications have demonstrated that monogenic diseases account for a significant percentage of adult cases of CKD. A substantial number of these patients have received a non-specific/incorrect diagnosis or a diagnosis of CKD of unknown etiology, which precludes correct treatment, follow-up and genetic counseling. There are a number of reasons why genetic kidney diseases are difficult to diagnose in adulthood: a) adult nephrologists, in general, are not knowledgeable about IKDs, b) existence of atypical phenotypes, c) genetic testing is not universally available, d) family history is not always available or may be negative, e) lack of knowledge of various genotype–phenotype relationships, f) conflicting interpretation of the pathogenicity of many sequence variants.

The incidence of kidney disease is rising, constituting a significant burden on the healthcare system and making identification of new therapeutic targets increasingly urgent. The heme oxygenase (HO) system performs an important function in the regulation of oxidative stress and inflammation and, via these mechanisms, is thought to play a role in the prevention of non-specific injuries following acute renal failure or resulting from chronic kidney disease. The expression of HO-1 is strongly inducible by a wide range of stimuli in the kidney, consequent to the kidney’s filtration role which means HO-1 is exposed to a wide range of endogenous and exogenous molecules, and it has been shown to be protective in a variety of nephropathological animal models. Interestingly, the positive effect of HO-1 occurs in both hemolysis- and rhabdomyolysis-dominated diseases, where the kidney is extensively exposed to heme (a major HO-1 inducer), as well as in non-heme-dependent diseases such as hypertension, diabetic nephropathy or progression to end-stage renal disease. This highlights the complexity of HO-1’s functions, which is also illustrated by the fact that, despite the abundance of preclinical data, no drug targeting HO-1 has so far been translated into clinical use. The objective of this review is to assess current knowledge relating HO-1’s role in the kidney and its potential interest as a nephroprotection agent. The potential therapeutic openings will be presented, in particular through the identification of clinical trials targeting this enzyme or its products.

ObjectivesA rising burden from end-stage kidney disease with poor outcomes in the frail, elderly population has seen the emergence of a non-dialytic option, also known as maximum conservative management (MCM). Despite an established MCM programme in our institution, it was anecdotally observed that some MCM patients would end up being dialysed short and long term. We explored treatment modality changes from MCM to renal replacement therapy (RRT), the reasons surrounding the change, and aimed to quantify survival in this cohort of patients.Methods44 patients were identified as being MCM, who changed modalities to RRT, from 2000 to 2015, using the Royal Free Hospital Renal Unit’s database. Electronic health records were reviewed retrospectively. Associations with 12-month mortality were explored and Kaplan-Meier method used to predict survival.ResultsThe most common modality change was to haemodialysis (81%), with one transplantation, and rest peritoneal dialysis. 28 patients commenced dialysis as unplanned starters, with the most common symptom being fluid overload. One-year survival was associated with increased age (75 vs 83, p=0.004, for alive vs dead) and had lower mean Charlson Comorbidity Index (6.2 vs 7.3, p=0.021). Median survival of 65 months following RRT initiation was predicted by the Kaplan-Meier method.ConclusionsPatients changed modalities from MCM to RRT due to symptoms, the most common being fluid overload. Despite an unplanned change to RRT, survival appears to be significant at 65 months in this study, indicating clinicians are continuing to offer RRT to patients appropriately.
