Background: The triglyceride-glucose (TyG) Index is a reliable alternative biomarker of insulin resistance, but the association between the TyG Index and acute kidney injury(AKI) in critically ill patients remains unclear. Methods: The data for the study was extracted from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Cox regression and restricted cubic spline(RCS) analysis were performed to analyze the association between the TyG index and all cause mortality. Besides, cox regression was carried out in subgroups of age, gender, BMI, diabetes history and dialysis status. Results: A total of 7508 critically ill participants with AKI from the MIMIC-IV database were included in study, with 3688(49.12%) participants failed to survive. In cox regression, after confounder adjustment, patients with a higher TyG Index had a higher risk of all cause mortality (HR = 1.845, 95% CI =1.49-2.285, p <0.001). In RCS, after confounder adjustment, the risk of death was positively correlated with the increased value of the TyG index when TyG index surpassed 10.014. This relationship was validated in age, gender, BMI and diabetes subgroups but not in the dialysis subgroup. Interestingly, RCS analysis demonstrated that, in patients undertaking dialysis, there is a “U” shape curve for the value of TyG index and risk of all cause mortality. When TyG index is less than 10.460, the risk of all cause mortality would decrease with the increase value of TyG index, while when TyG index is higher than 11.180, the risk of all cause mortality would increase firmly with the increase value of TyG index. Conclusion: Overall, higher TyG index is associated with higher risk of all-cause mortality in critically ill AKI. Interestingly, the relationship in dialysis subgroup follows a "U"-shaped curve, indicating the importance of a properly clinical blood glucose and lipid management of this particular population.

Background: Hypoxia-inducible factor-prolyl hydroxylase inhibitors (HIF-PHIs) are novel oral agents used for renal anemia treatment. Roxadustat, a first-in-class HIF-PHI used for treating anemia in chronic kidney disease patients, has been approved in China, Japan, South Korea, Chile, and Europe. Roxadustat is involved in HIF degradation, which can stimulate endogenous erythropoietin (EPO) production and improve iron utilization. Besides, roxadustat can promote dietary iron uptake and transport. In comparison with traditional erythropoiesis-stimulating agent (ESA) treatment, it might reduce cardiovascular risk and mortality as it causes only a slight increase in the plasma EPO level. Phase II and III clinical trial reports have shown that roxadustat is effective for treating chronic kidney disease patients. The role of roxadustat in kidney transplant recipients (KTRs) needs to be examined as patients with chronic kidney disease are different from those receiving renal transplants. Summary: Clinical trials have demonstrated that roxadustat effectively increases and maintains hemoglobin levels in patients with dialysis-dependent and non-dialysis-dependent chronic kidney disease by stimulating endogenous EPO production and optimizing iron utilization. Roxadustat has recently been used effectively to treat patients with EPO-resistant anemia. It has also been used for treating patients with post-transplant anemia (PTA), which is a prognostic factor for mortality in kidney transplant recipients with an iron deficiency and impaired glomerular filtration rate. Here, we examined the findings of four studies in a narrative review and discussed our perspectives regarding this field of study. Key Messages: Roxadustat significantly improves hemoglobin levels without affecting renal function in KTRs with PTA. It also enhances iron utilization by decreasing ferritin and hepcidin levels and increasing total iron binding capacity, transferrin, and serum iron levels. Roxadustat ameliorates anemia and inflammation, and might have reno-protective effects in KTRs.

Introduction: Steroid resistant nephrotic syndrome (SRNS) is the second most common cause of end-stage kidney disease in children, mostly associated with focal segmental glomerulosclerosis (FSGS). Advances in genomic science have enabled the identification of causative variants in 20 – 30% of SRNS patients. Methods: We used whole exome sequencing (WES) to explore the genetic causes of SRNS in children. Totally 101 patients with SRNS, and 13 patients with nephrotic proteinuria and FSGS were retrospectively enrolled in our hospital between 2018 and 2022. For the known monogenic causes analysis, we generated a known SRNS gene list of 71 genes through reviewing the OMIM database and literature. Results: Causative variants were identified in 23.68% of our cohort, and the most frequently mutated genes in our cohort were WT1 (7/27), NPHS1 (3/27), ADCK4(3/27), and ANLN (2/27). Five patients carried variants in phenocopy genes, including MYH9, MAFB, TTC21B, AGRN, and FAT4. The variant detection rate was the highest in the two subtype groups with congenital nephrotic syndrome and syndromic SRNS. In total, 68.75% of variants we identified were novel, and have not been previously reported in literature. Conclusion: Comprehensive genetic analysis is key to realizing the clinical benefits of a genetic diagnosis. We suggest that all children with SRNS undergo genetic testing, especially those with early onset and extrarenal phenotypes.

Background: Atherosclerotic renal artery stenosis (ARAS) is a condition where the renal arteries become narrowed due to atherosclerosis, leading to reduced blood flow to the kidneys and various renal complications. The effectiveness of interventional treatments, such as renal artery angioplasty and stenting, remains debated, making patient selection for these procedures challenging. Summary: This review focuses on the diagnosis and management of ARAS, with a particular emphasis on the potential role of functional MRI in evaluating renal function and mechanisms. By summarizing current diagnostic approaches and outcomes of interventional treatments, the review highlights the importance of informed clinical decision-making in ARAS management. Functional MRI emerges as a promising non-invasive tool to assess renal function, aiding in patient stratification and treatment planning.Key Messages:The efficacy of interventional treatments for ARAS requires further investigation and careful patient selection. Functional MRI holds promise as a non-invasive means to assess renal function and mechanisms, potentially guiding more effective clinical decisions in ARAS management. Advancing research in diagnostic methods, particularly functional MRI, can enhance our understanding and improve the treatment outcomes for ARAS patients.

Introduction: Perirenal fat is a pad that fills the retroperitoneal space outside the kidney, which affects kidney function in various ways. However, the association between perirenal fat and IgA nephropathy (IgAN) has not yet been elucidated. This study aimed to investigate the role of perirenal fat in predicting IgAN progression. Methods: A total of 473 patients with biopsy-proven IgAN and follow-up information were recruited, and perirenal fat thickness (PFT) was measured using color Doppler ultrasonography at renal biopsy. Patients were divided into two groups according to the median PFT: the low-PFT group (PFT ≤1.34 cm, n = 239) and the high PFT group (PFT >1.35 cm, n = 234). A total of 473 healthy participants were included in the control group. Basic clinical characteristics were assessed at the time of renal biopsy, and the relationship between PFT and combined endpoints was analyzed. The renal composite endpoints were defined as a two-fold increase in blood creatinine level, end-stage renal disease (dialysis over 3 months). Kaplan-Meier survival analysis was used to explore the role of PFT in the progression of IgAN. Three clinicopathological models of multivariate Cox regression analysis were established to evaluate the association between PFT and renal prognosis in patients with IgAN. Results: Compared to healthy subjects, patients with IgAN showed significantly higher PFT. After a median follow-up of 50 months, 75 of 473 patients (15.9%) with IgAN reached renal composite endpoints. Among those, 13 of 239 patients (5.4%) were in the low PFT group, and 62 of 234 patients (26.5%) were in the high PFT group (p < 0.001). The results of three Cox regression models (including demographics, pathological and clinical indicators, and PFT) demonstrated that a higher PFT was significantly associated with a higher risk of reaching renal composite endpoints in patients with IgAN. Conclusion: This study indicated a positive relationship between PFT at renal biopsy and renal progression in patients with IgAN, suggesting that perirenal fat might act as a marker of poor prognosis in patients with IgAN.

Background: Chronic kidney disease (CKD) is associated with a high burden of coronary artery disease (CAD), which remains the leading cause of death in CKD patients. Despite the high cardiovascular risk, ACS patients with renal dysfunction are less commonly treated with guideline-based medical therapy and are less frequently referred for coronary revascularization. Summary: The management of CAD is more challenging in patients with CKD than in the general population due to concerns regarding side effects and renal toxicity, as well as uncertainty regarding clinical benefit of guideline-based medical therapy and interventions. Patients with advanced CKD and especially those receiving dialysis have not traditionally been represented in randomized trials evaluating either medical or revascularization therapies. Thus, only scant data from small prospective studies or retrospective analyses are available. Recently published studies suggest that there are significant opportunities to substantially improve both cardiovascular and renal outcomes of patients with CAD and CKD, including new medications and interventions. Thus, the objective of this review is to summarize the current evidence regarding the management of CAD in CKD patients, in particular with respect to improvement of both cardiovascular and renal outcomes. Key Messages: Adequate medical therapy and coronary interventions using evidence-based strategies can improve both cardiac and renal outcomes in patients with CAD and CKD.

Introduction: The long-term impact of renin-angiotensin system (RAS) inhibitors for secondary prevention in patients with chronic kidney disease (CKD) and coexisting coronary artery disease remains unclear. Methods: Altogether, 1,160 consecutive patients with CKD (mean age, 70 ± 9 years; 78% men) who underwent their first percutaneous coronary intervention (PCI) between 2000 and 2018 were included and analyzed. Based on their RAS inhibitor use, 674 patients (58%) were allocated to the RAS inhibitor group, and 486 patients (42%) were allocated to the non-RAS inhibitor group. This study evaluated the incidence of 3-point major adverse cardiovascular events (3P-MACE), including cardiovascular death, nonfatal acute coronary syndrome and nonfatal stroke, admission for heart failure (HF), target vessel revascularization (TVR), and all-cause death. Results: During a median follow-up duration of 7.8 years, 280 patients (24.1%) developed 3P-MACE, 134 patients (11.6%) were hospitalized for HF, 171 patients (14.7%) underwent TVR, and 348 patients (30.0%) died of any causes. The cumulative incidence rate of 3P-MACE in the RAS inhibitor group was significantly lower than in the non-RAS inhibitor group (31.7% vs. 39.0%, log-rank test, p = 0.034); however, that of admission for HF in the RAS inhibitor group was significantly higher than in the non-RAS inhibitor group (28.1% vs. 13.3%, log-rank test, p < 0.001). The subgroup of preserved ejection fraction, non-acute myocardial infarction, and non-proteinuria tended to promote the onset of HF rather than cardiovascular prevention by RAS inhibitors. Conclusion: The long-term RAS inhibitor use for patients with CKD after PCI might prevent cardiovascular events but increase the risk of HF.

Introduction: It is still controversial whether automated peritoneal dialysis (APD) or hemodialysis (HD) is a more favorable choice for the rapid initiation of peritoneal dialysis. Methods: A pilot randomized prospective controlled trial was carried out in Shanghai Ruijin Hospital. Sixty-seven patients who chose long-term peritoneal dialysis treatment and needed unplanned dialysis were enrolled and randomized into HD-CAPD group (33 cases) or APD-CAPD group (34 cases) based on the dialysis modality during the transition period (within 14 days from the day PD catheter was implanted). Continuous ambulatory peritoneal dialysis started after the transition period. The primary outcome was the decline rates of residual glomerular filtration rate (GFR). Secondary outcomes included the rates of mechanical complications, the rates of infectious complications and complications of ESRD. Results: We found residual GFR decline were faster in HD-CAPD group than in APD-CAPD group (0.06 ml/min/w vs 0.03ml/min/w, P<0.01). The incidences of mechanical complications were similar in APD-CAPD group comparing with HD-CAPD group, including hernia (2.9% vs 3.0%, P=1.00), catheter malposition (0.02 episodes/patient-months vs 0.02 episodes/patient-months, P=0.70), leakage (5.9% vs 6.1%, P=1.00) and omental wrap (0 episode vs 3 episodes, P=0.368). Though the one-year overall infection rates were similar (0.03 episodes/patient-months vs 0.05 episodes/patient-months, P=0.10), APD-CAPD group had lower rate of bacteremia compared to HD-CAPD group (0 episodes/patient-months vs 0.02 episodes/patient-months, P<0.01). Conclusions: Both APD and HD could be used for patients who need to start dialysis in an unplanned manner. APD may have the advantage in protecting residual renal functions among these patients.
导读:对于腹膜透析的快速启动，自动腹膜透析(APD)还是血液透析(HD)是更有利的选择，目前仍存在争议。方法:在上海市瑞金医院进行随机前瞻性对照试验。选择长期腹膜透析治疗且需要计划外透析的患者67例，根据过渡期内(PD导管植入后14天内)透析方式随机分为HD-CAPD组(33例)和APD-CAPD组(34例)。转换期后开始持续门诊腹膜透析。主要终点是残余肾小球滤过率(GFR)的下降率。次要结局包括机械并发症发生率、感染并发症发生率和ESRD并发症发生率。结果:HD-CAPD组残GFR下降速度快于APD-CAPD组(0.06 ml/min/w vs 0.03ml/min/w, P<0.01)。APD-CAPD组机械并发症发生率与HD-CAPD组相似，包括疝(2.9% vs 3.0%， P=1.00)、导管移位(0.02次/患者-月vs 0.02次/患者-月，P=0.70)、漏尿(5.9% vs 6.1%， P=1.00)和网膜包膜(0次vs 3次，P=0.368)。尽管一年总体感染率相似(0.03次/患者-月vs 0.05次/患者-月，P=0.10)，但APD-CAPD组菌血症发生率低于HD-CAPD组(0次/患者-月vs 0.02次/患者-月，P= 0.01)。结论:APD和HD均可用于非计划开始透析的患者。在这些患者中，APD可能在保护残余肾功能方面具有优势。

Background: tRNA-derived small RNAs (tsRNAs) are an emerging class of small noncoding RNAs derived from tRNA cleavage. Summary: With the development of high-throughput sequencing, various biological roles of tsRNAs have been gradually revealed, including regulation of mRNA stability, transcription, translation, direct interaction with proteins and as epigenetic factors, etc. Recent studies have shown that tsRNAs are also closely related to renal disease. In clinical acute kidney injury (AKI) patients and preclinical AKI models, the production and differential expression of tsRNAs in renal tissue and plasma were observed. Decreased expression of tsRNAs was also found in urine exosomes from chronic kidney disease patients. Dysregulation of tsRNAs also appears in models of nephrotic syndrome and patients with lupus nephritis. And specific tsRNAs were found in high glucose model in vitro and in serum of diabetic nephropathy patients. In addition, tsRNAs were also differentially expressed in patients with kidney cancer and transplantation. Key Messages: In the present review, we have summarized up-to-date works and reviewed the relationship and possible mechanisms between tsRNAs and kidney diseases.
