This study investigated whether the metabolic syndrome (MetS) severity (MSSS) at diagnosis could predict poor outcomes during follow-up in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) patients with MetS. The equation for the MSSS at diagnosis used in this study was developed and validated in Korean adults aged 20–59 years. The medical records of 261 patients with AAV were retrospectively reviewed, and finally, 36 AAV patients with MetS aged 20–59 years fulfilling the inclusion criteria were included in this study. All-cause mortality, relapse, end-stage kidney disease (ESKD), cerebrovascular accident, and cardiovascular disease were assessed as the poor outcomes of AAV. Their median age was 51.2 years and 36.1% were male. The MSSS was significantly correlated with age and serum albumin but not AAV-specific indices. Among the five poor outcomes, only ESKD showed a relatively significant area under the curve (area 0.696) in receiver operating characteristic curve analysis. In the multivariable Cox hazards model analysis, both serum creatinine (HR 3.033) and MSSS (HR = 2.221) were significantly associated with ESKD occurrence. When the cut-off of the MSSS for ESKD was set at 1.72, ESKD occurred more frequently in patients with MSSS ≥ 1.72 than in those with MSSS < 1.72 (75.0% versus 14.3%, p = 0.002). Furthermore, patients with MSSS ≥ 1.72 exhibited a significantly lower cumulative ESKD-free survival rate than those with MSSS < 1.72 (p = 0.001). MSSS at the time of AAV diagnosis independently predicted the occurrence of ESKD during follow-up in patients with AAV and MetS.

<b><i>Background:</i></b> The association between fruit and vegetable (FV) intake and the risk of end-stage kidney disease (ESKD) has not been examined in the general population and fully explored in chronic kidney disease (CKD). We prospectively evaluated this relationship in US representative sample of adults and evaluated consistency by the presence or absence, and severity, of CKD. <b><i>Methods:</i></b> We used data from the Third National Health and Nutrition Examination Survey (1988–1994) linked with the US Renal Data System, including 14,725 adults aged ≥20 years and with follow-up for ESKD through 2008. Daily FV intake was ascertained using a food frequency questionnaire. We examined the association between selected categories of FV intake and ESKD using a Fine Gray competing risk model adjusting for sociodemographics, lifestyle, clinical and nutritional factors, estimated glomerular filtration rate, and albuminuria. We evaluated whether risk varied in individuals with severe versus any CKD. <b><i>Results:</i></b> 230 participants (1.5%) developed ESKD during follow-up. In the adjusted model, compared to highest intake, those in lowest categories of FV intake had a higher risk of ESKD, for &#x3c;2 times/day (1.45 [1.24–1.68], 2 to &#x3c;3 times/day (1.40 [1.18–1.61]), 3 to &#x3c;4 times/day (1.25 [1.04–1.46]), and 4 to &#x3c;6 times/day (1.14 [0.97–1.31]). There was suggestion of heterogeneity (<i>p</i> for interaction = 0.03) with possible stronger inverse association in patients with CKD than those without CKD. After stratification, we obtained similar strong inverse association when we examined ESKD incidence across intake of FVs in participants with CKD stages 1–4 (<i>n</i> = 5,346) and specifically in those with CKD stages 3–4 (<i>n</i> = 1,084). <b><i>Conclusions:</i></b> Low intake of FVs was associated with higher risk of ESKD in US adults with and without CKD, supporting an emerging body of literature on the potential benefits of plant-rich diets for prevention of ESKD.

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.

Obesity is a potent risk factor for kidney disease as it increases the possibility of developing diabetes and hypertension, and it has a direct impact on the development of chronic kidney disease and end-stage renal disease. In this study, we tested the effect of bergamot polyphenolic fraction in a cafeteria with diet-fed rats, an excellent experimental model for studying human metabolic syndrome, as it is able to induce severe obesity with insulin resistance and high plasma triglyceride levels more efficiently than a traditional lard-based high-fat diet used in rodent models. We analyzed the plasmatic oxidative balance by photometric tests, and the expression of cytoplasmic antioxidant enzymes (superoxide dismutase 1 and glutatione S-tranferasi P1) and apoptotic markers (Caspase 8 and 9) in kidney tissues by Western blot analysis. Our results clearly showed that the cafeteria diet induces a marked pro-oxidant effect: significant reduction of plasmatic antioxidant capacity; downregulation of cytoplasmic antioxidant enzymes expression; and activation of apoptotic pathways. All these hallmarks of redox disequilibrium were mitigated by treatment with polyphenolic fraction of bergamot, highlighting its antioxidant effect in the metabolic syndrome. Our data show that the link between obesity and renal damage could be represented by oxidative stress.

Background Large epidemiological studies have demonstrated an early survival advantage with the initiation of peritoneal dialysis (PD) compared to haemodialysis (HD). Chronic inflammation may contribute to atherosclerosis and cardiovascular (CVD) mortality in end-stage kidney disease (ESKD). We hypothesize that the initiation of HD in ESKD patients is associated with a greater inflammatory response compared with PD. Aims To examine the effects of initiating HD and PD upon inflammation and CVD risk markers in ESKD patients. Methods We per formed a pilot prospective study on 75 predialysis CKD stage-5 subjects comparing the effects of HD and PD upon high sensitivity C-reactive protein (hsCRP), interleukin(IL)-12, IL-18 and pulse wave velocity (PWV). Study visits were conducted 3 – 6 months before (baseline) and after (follow-up) initiation of dialysis Results Thirty-nine and 36 patients were initiated on HD and PD respectively. HD patients were older than PD patients (65.1 ± 2.1 vs 57.7 ± 2.7 years; p = 0.03) but had similar baseline systolic blood pressure (SBP), pulse pressure (PP), hsCRP, IL-12, IL-18, and PWV. At follow-up, HD patients had significantly increased hsCRP levels [5.2(3.7, 7.3) vs 1.7(1.0, 2.8)g/L; p < 0.001] compared to PD. Follow-up blood pressure, IL-12, IL-18, and PWV were similar between groups. A significant association remained between hsCRP and HD after adjustment for age, previous CVD, and residual urine output. Conclusion The initiation of HD was associated with significantly increased hsCRP compared to PD. Further study is required to determine the plausibility of inflammation as a potential underlying contributor to the observed early mortality difference between dialysis modalities.

Introduction Prevalence of cognitive impairment increases with worsening severity of chronic kidney disease (CKD) and majority of end-stage kidney disease (ESKD) patients on dialysis have cognitive impairment. Trends of cognitive function (CF) in this population are less well known with published studies reporting conflicting results. Methods We assessed CF in a cohort of non-dialysis CKD and ESKD patients undergoing dialysis using modified mini-mental state examination (3MS), trail-making test (TMT-A & B) scores and Stroop task, and evaluated demographics, comorbidities and depression using Beck depression inventory at baseline. We repeated tests of CF and depression ≥ 1-year after baseline in both groups and compared change scores in CF and depression between ESKD/ CKD sub-groups. Among ESKD patients we compared change scores between patients with dialysis vintage of <1-year and >1-year. Analysis of covariance was used to adjust for the effect of age on these change scores. Results At baseline (N = 211), compared to CKD (N = 108), ESKD (N = 103) patients had significantly worse CF based on 3MS and TMT-A & B scores, and depression scores. On follow-up (N = 160) 3MS scores, especially the memory subscale significantly improved in ESKD, but worsened in CKD, with no significant changes in TMT A /TMT-B, or depression scores after adjusting for age. Among ESKD patients, 3MS, especially memory subscale improved in patients with dialysis vintage <1-year compared to >1-year. The 51 patients who discontinued after baseline assessment had worse baseline CF scores suggesting differential attrition. Conclusion Though baseline cognitive scores were worse in ESKD patients on dialysis, compared to CKD, their 3MS, especially memory subscale improved on follow-up. Among ESKD patients, the improvement was significant only in patients who have been on dialysis for less than one-year which may indicate a beneficial effect of clearance of uraemic toxins. Differential attrition of study subjects may have impacted the observed results.

Abstract Aims/hypothesis Few large-scale prospective studies have investigated associations between relative leucocyte telomere length (rLTL) and kidney dysfunction in individuals with type 2 diabetes. We examined relationships between rLTL and incident end-stage kidney disease (ESKD) and the slope of eGFR decline in Chinese individuals with type 2 diabetes. Methods We studied 4085 Chinese individuals with type 2 diabetes observed between 1995 and 2007 in the Hong Kong Diabetes Register with stored baseline DNA and available follow-up data. rLTL was measured using quantitative PCR. ESKD was diagnosed based on the ICD-9 code and eGFR. Results In this cohort (mean ± SD age 54.3 ± 12.6 years) followed up for 14.1 ± 5.3 years, 564 individuals developed incident ESKD and had shorter rLTL at baseline (4.2 ± 1.2 vs 4.7 ± 1.2, p < 0.001) than the non-progressors (n = 3521). On Cox regression analysis, each ∆∆Ct decrease in rLTL was associated with an increased risk of incident ESKD (HR 1.21 [95% CI 1.13, 1.30], p < 0.001); the association remained significant after adjusting for baseline age, sex, HbA1c, lipids, renal function and other risk factors (HR 1.11 [95% CI 1.03, 1.19], p = 0.007). Shorter rLTL at baseline was associated with rapid decline in eGFR (>4% per year) during follow-up (unadjusted OR 1.22 [95% CI 1.15, 1.30], p < 0.001; adjusted OR 1.09 [95% CI 1.01, 1.17], p = 0.024). Conclusions/interpretation rLTL is independently associated with incident ESKD and rapid eGFR loss in individuals with type 2 diabetes. Telomere length may be a useful biomarker for the progression of kidney function and ESKD in type 2 diabetes. Graphical abstract

Chinese herbal medicine (CHM) might have benefits in patients with non-diabetic chronic kidney disease (CKD), but there is a lack of high-quality evidence, especially in CKD4. This study aimed to assess the efficacy and safety of Bupi Yishen Formula (BYF) vs. losartan in patients with non-diabetic CKD4. This trial was a multicenter, double-blind, double-dummy, randomized controlled trial that was carried out from 11-08-2011 to 07-20-2015. Patients were assigned (1:1) to receive either BYF or losartan for 48 weeks. The primary outcome was the change in the slope of the estimated glomerular filtration rate (eGFR) over 48 weeks. The secondary outcomes were the composite of end-stage kidney disease, death, doubling of serum creatinine, stroke, and cardiovascular events. A total of 567 patients were randomized to BYF (n = 283) or losartan (n = 284); of these, 549 (97%) patients were included in the final analysis. The BYF group had a slower renal function decline particularly prior to 12 weeks over the 48-week duration (between-group mean difference of eGFR slopes: −2.25 ml/min/1.73 m2/year, 95% confidence interval [CI]: −4.03,−0.47), and a lower risk of composite outcome of death from any cause, doubling of serum creatinine level, end-stage kidney disease (ESKD), stroke, or cardiovascular events (adjusted hazard ratio = 0.61, 95%CI: 0.44,0.85). No significant between-group differences were observed in the incidence of adverse events. We conclude that BYF might have renoprotective effects among non-diabetic patients with CKD4 in the first 12 weeks and over 48 weeks, but longer follow-up is required to evaluate the long-term effects.Clinical Trial Registration:http://www.chictr.org.cn, identifier ChiCTR-TRC-10001518.

Pregnancy-induced changes in renal hemodynamics play an important role in favorable maternal and fetal outcomes. Renal plasma flow and glomerular filtration rate (GFR) increase by approximately 50% in normal pregnancy, leading to a decrease in both blood urea nitrogen and serum creatinine when compared with prepregnancy levels. Hence, serum creatinine–based formulas are not accurate in calculating estimated GFR in pregnant patients. The most compelling risk for pregnant women with moderate to severe chronic kidney disease is the risk of rapid progression of underlying kidney disease; the mechanisms for such decline are yet to be elucidated. The rule of kidney disease not progressing when serum creatinine is less than 1.4 mg/dL does not apply to women with lupus nephritis. New-onset lupus is an indication for kidney biopsy during pregnancy because diffuse proliferative lupus nephritis requires prompt treatment and first-line treatments are teratogenic. Infertility is common in women on dialysis and is usually reversed after successful kidney transplantation. Pregnancy outcomes have improved over the years with increasing intensity of hemodialysis in end-stage kidney disease patients. Pregnancy post–kidney transplantation should be planned and teratogenic medications discontinued before conception. Key words: glomerular filtration rate, proliferative lupus nephritis, serum creatinine, pregnancy post–kidney transplantation, end-stage kidney disease, infertility, kidney biopsy

We report herein an adult case of chronic kidney disease (CKD) associated with diabetes. The patient had been treated with insulin injection for diabetes 10 years ago. At the time of his first visit to our division for further examinations, we diagnosed him as CKD: cause (C) diabetes; glomerular filtration rate (GFR) (G) G5 (estimated [e] GFR, 10.2 mL/min/1.73 m2; serum creatinine of 4.90 mg/dL); and albuminuria (A) A3 (2.62 g/gCr) by the Japanese Society of Nephrology (JSN) CGA classification. Because he had complained of severe constipation and kidney function, i.e., eGFR was not improved by previous medications, we added on a minimal dosage (2 g/day) of AST-120 (Kremezin®; ordinary dose 6 g/day). After 3 months of AST-120 therapy, eGFR was increased to 17.8 mL/min/1.73 m2 (serum creatinine of 2.90–2.72 mg/dL). Although the patient used some laxative products, he could not continue to take Kremezin and completely stopped 8 months after starting this drug. Kidney function then abruptly declined and progressed to end-stage kidney disease (ESKD). In June 2017, he was introduced to hemodialysis. It appears that the adherence of Kremezin is very important for inhibiting the progression to ESKD for patients with CKD with diabetes.
