At present, there have been no detailed reports of acute kidney injury (AKI) resulting from bromadiolone poisoning. A 27-year-old woman was admitted to the hospital due to severe coagulopathy and severe AKI. Coagulation test revealed a prothrombin time exceeding 120 s and an international normalized ratio (INR) greater than 10. Further examination for coagulation factors showed significantly reduced level of factors II, VII, IX and X, indicating a vitamin K deficiency. The AKI was non-oliguric and characterized by gross dysmorphic hematuria. Following the onset of the disease, the patient’s serum creatinine rose from 0.86 to 6.96 mg/dL. Suspecting anticoagulant rodenticide poisoning, plasma bromadiolone was identified at a concentration of 117 ng/mL via gas chromatography/mass spectrometry. All other potential causes of AKI were excluded, except for the presence of a horseshoe kidney. The patient’s kidney function fully recovered after the coagulopathy was corrected with high doses of vitamin K and plasma transfusion. At a follow-up 160 days post-discharge, the coagulation function had normalized, and the serum creatinine had returned to 0.51 mg/dL. Bromadiolone can induce AKI through a severe and prolonged coagulation disorder. Kidney function can be restored within days following treatment with high-dose vitamin K1.","PeriodicalId":9089,"journal":{"name":"BMC Nephrology","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142185426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Implementation of this guidance is reliant upon an adequate and skilled rehabilitation workforce. Data relating to this is currently lacking within the UK. This survey aimed to identify variations and good practices in kidney physiotherapy (PT), occupational therapy (OT) and clinical exercise physiologist (CEP) provision; and to understand barriers to implementation. An online survey was sent to all 87 UK kidney units between June 2022 and January 2023. Data was collected on the provision of therapy services, barriers to service provision and responses to the COVID-19 pandemic. The quantitative survey was analysed using descriptive statistics. Free-text responses were explored using reflexive thematic analysis. Forty-five units (52%) responded. Seventeen (38%) units reported having a PT and 15 (33%) an OT with a specialist kidney role; one unit (7%) had access to a CEP. Thirty units (67%) offered inpatient therapy services, ten (22%) outpatient therapy clinics, six (13%) intradialytic exercise, six (13%) symptom management and three (7%) outpatient rehabilitation. Qualitative data revealed lack of money/funding and time (both n = 35, 85% and n = 34, 83% respectively) were the main barriers to delivering kidney-specific therapy. Responders saw an increase in the complexity of their caseload, a reduction in staffing levels and consequently, service provision during the COVID-19 pandemic. Exemplars of innovative service delivery, including hybrid digital and remote services, were viewed as positive responses to the COVID-19 pandemic. Despite clear evidence of the benefits of rehabilitation, across the UK, there remains limited and variable access to kidney-specific therapy services. Equitable access to kidney-specific rehabilitation services is urgently required to support people to ‘live well’ with kidney disease.","PeriodicalId":9089,"journal":{"name":"BMC Nephrology","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142185427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to create a LD-related signature to predict prognosis and guide the immunotherapy and targeted therapy in ccRCC patients. We conducted a comprehensive analysis using transcriptional profiles and clinical data obtained from The Cancer Genome Atlas (TCGA). LD-related genes were identified from existing literature and the GeneCards database, and differentially expressed genes were determined. Sequentially, we conducted Cox regression analysis and Lasso regression analysis, to establish a prognostic risk model. The performance of the risk model was evaluated using Kaplan–Meier (KM) analysis and time-dependent receiver operating characteristic (ROC) analysis. Additionally, gene set enrichment analysis (GSEA), ESTIMATE, CIBERSORT, and immunophenoscore (IPS) algorithm were used to assess the tumor microenvironment (TME) and treatment response. We constructed a risk signature with four LD-related genes in the TCGA dataset, which could be an independent prognostic factor in ccRCC patients. Then, patients were classified into two risk groups and exhibited notable differences in overall survival (OS), progression-free survival (PFS), and TME characteristics. Furthermore, we developed a comprehensive nomogram based on clinical features, which demonstrated good prognostic predictive value. According to the results of GSEA analysis, immune-related pathways were found to be significantly enriched in the high-risk group. Additionally, the high-risk group displayed high levels of immune cell infiltration, TMB and IPS scores, indicating better efficacy of immune checkpoint inhibitors (ICIs). Finally, high-risk demonstrated reduced IC50 values compared to the low-risk counterpart for specific targeted and chemotherapeutic drugs, suggesting that the patients receiving these targeted drugs in high-risk group had better treatment outcomes. Our findings suggested that the LD-related gene signature could potentially predict the prognosis of ccRCC patients. Additionally, it showed promise for predicting responses to immunotherapy and targeted therapy in ccRCC patients. These insights might potentially have guided the clinical management of these patients, but further validation and broader data analysis are needed to confirm these preliminary observations.","PeriodicalId":9089,"journal":{"name":"BMC Nephrology","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is an emerging move of guideline bodies advocating a more patient-centred approach. Aneurysms in autogenous arteriovenous fistula (AVF) can be considered unsightly and a constant reminder for patients of their dependence on dialysis. However, their impact on patient’s perception has not previously been reported. Between April 2017–18, the Vascular Access Questionnaire (VAQ) was administered to prevalent haemodialysis patients across ten dialysis units via structured interviews, as part of a quality improvement project. Data for the subgroup of patients with aneurysmal AVF (categorised as per classification by Valenti et al.), were retrospectively evaluated and compared to the wider cohort. Data were collected for 539 patients (median age: 66 years; 59% male), of whom 195 (36%) had aneurysmal AVF, with Type 2 morphology (cannulation site) being the most common (75%). Duration of AVF was found to be significantly associated with aneurysmal development, with estimated likelihoods of 11%, 43% and 61% after one, five and ten years, respectively. Interestingly, patients with diabetes had a significantly lower prevalence of aneurysmal development than those that were non-diabetic (25% vs. 43%, p < 0.001). Overall VAQ scores were not found to differ significantly by aneurysm status (p = 0.816) or across morphology types (p = 0.277). However, patients with aneurysmal AVF were significantly more concerned with the appearance of their AVF (p < 0.001) than the wider cohort. Despite this, patients with aneurysmal AVF gave significantly higher scores for satisfaction and ease of use and lower scores for bruising and clotting (p < 0.05). Aneurysmal AVF are often cited as an important factor by patients for not proceeding with fistula formation. In this evaluation of patient reported experiences, those with aneurysmal AVF reported high satisfaction levels. This may help clinicians highlight positive patient reported outcomes of aneurysmal AVF during preprocedural consent processes.","PeriodicalId":9089,"journal":{"name":"BMC Nephrology","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142185430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nephrologists’ kidney failure risk estimations were assessed: “On a scale of 0–100%, without using any estimating equations, give your best estimate of the risk that this patient will need dialysis or a kidney transplant in 2 years.” KFRE was calculated using age, sex, eGFR, serum bicarbonate, albumin, calcium, phosphorus, urine albumin/creatinine ratio. The outcomes were the pattern of referral to KRT education (within 90 days of initial visit) and kidney failure evaluated by chart review. The population was divided into groups either by nephrologists’ predictions or by KFRE.

DCFH-DA staining was utilized for the detection of cellular levels of ROS. WB and immunofluorescence were utilized to detect the expression of P4HB, epithelial-mesenchymal transition (EMT), fibrosis, and TGFβ/SMAD3-related proteins in HK-2 cells. Online databases were utilized for predicting the interaction target of P4HB, and immunoprecipitation (IP) experiments were employed to validate the binding of P4HB with the target. SiRNA and overexpression vectors of target gene were used to verify the mechanism of action of P4HB. HG induced an increase in the expression of P4HB and TGFβ, p-SMAD3, and ROS in HK-2 cells. Furthermore, HG downregulated the expression of E-cadherin and upregulated the expression of N-cadherin, Vimentin, α-SMA, Fibronectin, Collagen IV, SNAIL, and SLUG in HK-2 cells. Interfering with P4HB significantly reversed the expression of these proteins. Database predictions and IP experiments showed that P4HB interacts with PRMT1, and the expression of PRMT1 was increased in HG-induced HK-2 cells. Interfering with PRMT1 inhibited the changes in expression of EMT and fibrosis related proteins induced by HG. However, overexpression of PRMT1 weakened the regulatory effect of P4HB interference on the EMT, fibrosis, and TGFβ/SMAD3-related proteins in HK-2 cells. P4HB regulated the TGFβ/SMAD3 signaling pathway through PRMT1 and thus participates in HG-induced EMT and fibrosis in HK-2 cells.","PeriodicalId":9089,"journal":{"name":"BMC Nephrology","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142185474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim was to evaluate the efficacy and safety of oral cyclophosphamide (CYC) and mycophenolate mofetil (MMF) in children with steroid-sensitive nephrotic syndrome in terms of the proportion of children who have been off steroids for at least 6 months without proteinuria (responders). This open-label retrospective-prospective comparative study was conducted in a pediatric nephrology clinic of a referral center for children between 1 and 18 years of age with FR/SD nephrotic syndrome. Group A consisted of patients who received oral cyclophosphamide (100, 25% female) at a dose of 2–2.5 mg/kg once daily for a period of 8–12 weeks. Group B consisted of patients who received oral mycophenolate mofetil (n = 61, 18% female) (dose: 800–1200 mg/m2) for at least 12 months. Responders were defined as children who were off steroids for at least 6 months along with absence of proteinuria. In the CYC group, 50% of the patients were responders, whereas 54% of the patients in the MMF group were responders (p = 0.614). The time to first relapse with CYC was 7 months (IQR 5.25–11) compared to 7 months (IQR 3.5–12) with MMF (p = 0.092). The relapse rate in the CYC group was 1.77 relapses per patient-year compared to 1.295 relapses per patient-year in the MMF group. The difference in relapse rate was significant (-0.474; 95% CI, 0.09 to 0.86 relapses/person-year) (p value = 0.009).
