To prepare the dialysate at least 120 liters of water are needed for one four-hour session with a dialysate flow (Qd) set at 500 ml/min. Lower dialysate flow rate is associated with a significant reduction in the amount of water used. The aim of this study was to check whether change of Qd from 500 ml/min to 300 ml/min has a significant impact on dialysis adequacy.\u0000 \u0000 \u0000 \u0000 The study was a retrospective analysis. Due to administrative issues a satellite dialysis center reduced dialysate flow to 300 ml/min for a month. The center again increased Qd to 500 ml/min. We analyzed laboratory data from 3 months before dialysate flow reduction, in the month with reduced Qd to 300 ml/min, and from 3 months thereafter with Qd set at 500 ml/min.\u0000 \u0000 \u0000 \u0000 24 people were included in the final analysis. There were no significant changes in URR caused by lower rate of Qd (64.50 [61.75-71.00] vs 67.00 [63.00-72.25] vs 69.00 [63.75-72.25], ANOVA F(2,46)=0.71, p=0.50). Similarly, hemodialysis adequacy expressed by Kt/V did not differ at any Qd (1.23 [1.12-1.41] vs 1.25 [1.18-1.40] vs 1.35 [1.19-1.48], ANOVA F(2,46)=2.51, p=0.09). There was a small but statistically significant increase in mean predialysis K with lower Qd: (K = 5.18 (95%CI 4.96-5.44) vs. 5.46 (95%CI 5.23-5.69) vs. 5.23 (95%CI 4.99-5.47) mmol/l at Qd=500, 300, and 500 ml/min, respectively, p=0.039.)\u0000 \u0000 \u0000 \u0000 Reduction in dialysate flow rate to 300 ml/min seems safe and does not cause any short-term negative effects in this small study.

Methods The prognoses of individuals with estimated glomerular filtration rates (eGFR) &amp;lt; 90 ml/min/1.73 m2 were evaluated based on the KDIGO heatmap using an electronic medical record database in Japan. The primary outcome was major adverse cardiovascular events (MACE), a composite of myocardial infarction (MI), stroke, heart failure (HF) hospitalization, and in-hospital death (referred to as MACE1). Additionally, ad hoc MACE2 (MI hospitalization, stroke hospitalization, HF hospitalization, and in-hospital death) was examined. The secondary outcome was the renal outcome. Results Of the 543 606 individuals included, the mean age was 61.6 ± 15.3 years, 50.1% were male, and 40.9% lacked urine protein results. The risk of MACEs increased independently with both eGFR decline and increasing proteinuria from the early KDIGO stages: Hazard ratios (with 95% confidence interval) of MACE1 and MACE2, compared to G2A1 were 1.16 (1.12–1.20) and 1.17 (1.11–1.23), respectively, for G3aA1, and 1.17 (1.12–1.21) and 1.35 (1.28–1.43), respectively, for G2A2. This increased up to 2.83 (2.54–3.15) and 3.43 (3.00–3.93), respectively, for G5A3. Risks of renal outcomes also increased with CKD progression. Conclusions This study is the first to demonstrate the applicability of the KDIGO heatmap in assessing cardiovascular and renal risk in Japan. The risk increased from the early stages of CKD, indicating the importance of early diagnosis and intervention through appropriate testing.","PeriodicalId":10435,"journal":{"name":"Clinical Kidney Journal","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141881260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is clear that the prevalence of CKD among aging population is significantly elevated. It involves a board range of complex and poorly understood concerns in older adults such as frailty, malnutrition, sarcopenia, and even cognitive and mental dysfunction. In kidneys, renal function such as glomerular filtration, urine concentration and dilution, and homeostasis of sodium and potassium, can be influenced by the aging process. In addition, it's worth noting that CKD and end stage of kidney disease (ESRD) patients are often accompanied by an activation of immune system and inflammation. It involves both the innate and adaptive immune system.

Despite efforts to standardize AKI management, its recognition in clinical practice is limited. Methods To assess and characterize different patterns of AKI diagnosis, we collected clinical data, serum creatinine (sCr) levels, comorbidities, and outcomes from adult patients using the Hospital Discharge Form (HDF). AKI diagnosis was based on administrative data and according to KDIGO criteria by evaluating sCr variations during hospitalization. Additionally, patients were also categorized based on the timing of AKI onset. Results Among 56 820 patients, 42 900 (75.5%) had no AKI, 1 893 (3.3%) had AKI diagnosed by sCr changes and coded in HDF (Full-AKI), 2 529 (4.4%) had AKI reported on HDF but not meeting sCr-based criteria (HDF-AKI), and 9 498 (16.7%) had undetected AKI diagnosed by sCr changes but not coded in HDF (KDIGO-AKI). Overall, AKI incidence was 24.5%, with a 68% undetection rate. Patients with KDIGO-AKI were younger, had a higher proportion of females, lower comorbidity burden, milder AKI stages, more frequent admissions to surgical wards, and lower mortality compared to Full-AKI. All AKI groups had worse outcomes than those without AKI, and AKI, even if undetected, was independently associated with mortality risk. Patients with AKI at admission had different profiles and better outcomes than those developing AKI later. Conclusions AKI recognition in hospitalized patients is highly heterogeneous, with a significant prevalence of undetection. This variability may be affected by patients ‘characteristics, AKI-related factors, diagnostic approaches, and in-hospital patient management. AKI remains a major risk factor, emphasizing the importance of ensuring proper diagnosis for all patients.","PeriodicalId":10435,"journal":{"name":"Clinical Kidney Journal","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141778769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CSA-AKI develops due to a combination of patient- and surgery-related risk factors that enhance renal ischemia-reperfusion injury. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) such as empagliflozin reduce renal glucose reabsorption, improving tubulo-glomerular feedback, reducing inflammation, and decreasing intraglomerular pressure. Preclinical studies have observed that SGLT2i may provide significant protection against renal ischemia-reperfusion injury due to its effects over inadequate mitochondrial function, reactive oxygen species activity, or renal peritubular capillary congestion, all hallmarks of CSA-AKI. The VERTIGO trial is a Phase 3, investigator-initiated, randomized, double-blind, placebo-controlled, multicenter study that aims to explore if empagliflozin can reduce the incidence of adverse renal outcomes in cardiac surgery patients. Methods The VERTIGO study (EudraCT: 2021–004938-11) will enroll 608 patients that require elective cardiac surgery with ECC. Patients will be randomly assigned in a 1:1 ratio to receive either empagliflozin 10 mg orally daily or placebo. Study treatment will start five days before surgery and will continue during the first seven postoperative days. All participants will receive standard care according to local practice guidelines. The primary endpoint of the study will be the proportion of patients that develop major adverse kidney events during the first 90 days after surgery, defined as 25% or greater renal function decline, renal replacement therapy initiation, or death. Secondary, tertiary, and safety endpoints will include rates of acute kidney injury during index hospitalization, postoperative complications, and observed adverse events. Conclusions The VERTIGO trial will describe the efficacy and safety of empagliflozin in preventing CSA-AKI.

Method From 2010 to 2012, 421 patients with biopsy-proven IgAN have been enrolled into the German Chronic Kidney Disease (GCKD) cohort, a prospective observational cohort study (N = 5217). Adjudicated endpoints included a Composite Kidney Endpoint (CKE) consisting of eGFR decline &amp;gt; 40%, eGFR &amp;lt; 15 ml/min/1.73 m2 and initiation of kidney replacement therapy; the individual components of the CKE; and combined major adverse cardiac events (MACE), including nonfatal myocardial infarction, nonfatal stroke, and all-cause mortality. The associations between the incidence of CKE and baseline factors, including demographics, laboratory values and comorbidities were analyzed using the Cox proportional hazards regression model. Results The mean age at baseline of IgAN patients was 51.6 years (± 13.6) and 67% were male. Patient-reported duration of disease at baseline was 5.9 ± 8.1 years. Baseline median UACR was 0.4 g/g (0.1–0.8) and mean eGFR was 52.5 ± 22.4 mL/min/1.73m2.

Methods A single-centre prospective study (October 2018–April 2023) enrolled children with SRNS, undergoing renal biopsy and genetic testing per institutional protocol. Clinical, histological, and genetic data were recorded. DNA isolation and next-generation sequencing were conducted for genetic analysis. Data collection included demographics, clinical parameters, and kidney biopsy findings. Syndromic features were evaluated, with second-line immunosuppressive therapy administered.
