While immunosuppressive therapies like cyclophosphamide (CTX) and mycophenolate mofetil (MMF) are commonly used, evidence regarding the efficacy and safety of tacrolimus (TAC) in HSPN remains limited. This study presents the first systematic review and meta-analysis specifically evaluating the efficacy and safety of tacrolimus (TAC) in treating Henoch-Schönlein purpura nephritis (HSPN), aiming to fill a critical gap in evidence for clinical decision-making.</p><p><strong>Methods: </strong>This systematic review and meta-analysis, the first focused specifically on TAC in HSPN, included seven studies comprising 727 patients. A comprehensive search was conducted across multiple databases, including the Cochrane Library, PubMed, Embase, Medline, Web of Science, CNKI, Wanfang, SinoMed, VIP, and Embase. Studies comparing TAC with control treatments, such as CTX or MMF, in HSPN patients were included. Odds ratios (ORs) were calculated for dichotomous outcomes, while standardized mean differences (SMDs) with 95% confidence intervals (CIs) were used for continuous variables. Depending on heterogeneity, either random-effects or fixed-effects models were applied. Data synthesis was performed using RevMan software.</p><p><strong>Results: </strong>A total of seven studies were included. TAC therapy significantly improved clinical efficacy in HSPN patients (OR = 4.43; 95% CI: 2.86-6.87; P < 0.001). Additionally, TAC significantly reduced urine protein levels (SMD = -1.17; 95% CI: -1.83 to -0.51; P < 0.001), serum creatinine (Scr) (SMD = -2.33; 95% CI: -3.00 to -1.65; P < 0.001), and blood urea nitrogen (BUN) (SMD = -1.49; 95% CI: -1.94 to -1.04; P < 0.001). Importantly, there were no significant differences in the incidence of adverse events between the TAC and control groups.</p><p><strong>Conclusion: </strong>This is the first systematic review and meta-analysis specifically evaluating TAC in HSPN, providing novel evidence that TAC is an effective and safe therapeutic option for these patients.

Meprin metalloproteinases have been implicated in the pathophysiology of IR-induced kidney injury. Existing data from in vitro and in vivo studies show that meprins modulate interleukin-6 (IL-6)-mediated inflammation via proteolytic processing of IL-6 and its receptor. IL-6 trans-signaling induces proliferation through either Mitogen-activated protein kinase /extracellular signal-regulated kinase (MAPK/ERK) or Phosphatidylinositol 3-Kinase/ protein kinase B (PI3K/AKT) pathway or in crosstalk with AKT/ERK. We previously showed that meprin β modulates cellular survival B-Cell Lymphoma/Leukemia 2 (BCL-2) through IL-6/Janus kinase/ Signal Transducer and Activator of Transcription (IL-6/JAK/STAT) signaling pathway in IR-induced kidney injury. However, it's not known how meprin β modulation of the IL-6 signaling pathway impacts the cellular proliferation in IR-induced acute kidney injury. The goal of the current study was to determine how meprin β modulation of the IL-6 signaling pathway impacts downstream cellular proliferation in IR-induced kidney injury.</p><p><strong>Methods: </strong>We induced Ischemia/Reperfusion injury with unilateral IR as a model of renal inflammation in wild-type (WT) and meprin β knockout (βKO) mice, with the contralateral kidneys serving as controls.

However, the baseline mRNA levels for PCNA were significantly higher in βKO when compared to WT kidneys. Immunohistochemical data showed significant increases in IL-6, PCNA, p-AKT and p-ERK in select tubules in both genotypes at 96 h post-IR when compared to control kidneys for each genotype. Data from immunofluorescence counterstaining of kidney tissues revealed that at 96 hours post-IR, IL-6, PCNA, p-AKT, and p-ERK were primarily expressed in meprin β-expressing proximal tubules (PTs), where meprins are abundantly present. However, high levels of IL-6 were also present in the lumen of PTs and DTs from WT and βKO kidneys at 96 h post-IR, suggesting increased release/shedding into filtrate and subsequently into urine.</p><p><strong>Conclusion: </strong>In conclusion, this study highlights the role of meprin β activity in regulating cellular proliferation through PCNA regulation, driven by the IL-6-mediated AKT/ERK signaling pathway during the recovery phase following IR-induced kidney injury.</p><p><strong>Clinical trial number: </strong>Not applicable.</p>","PeriodicalId":9089,"journal":{"name":"BMC Nephrology","volume":"26 1","pages":"467"},"PeriodicalIF":2.4,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12363113/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144871418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It aims to provide guidance on how to provide vascular access care for patients approaching and undergoing haemodialysis, and provides a standard of care which centres should in general aim to achieve. We would not advise patients to interpret the guideline as a rulebook, but perhaps to answer the question: \"What does good quality vascular access care look like?\". The guideline is split into sections: each begins with a few statements which are graded by strength (1 is a firm recommendation, 2 is more like a sensible suggestion), and the type of research available to back up the statement, ranging from A (good quality trials so we are pretty sure this is right) to D (more like the opinion of experts than known for sure). After the statements there is a short summary explaining why we think this, often including a discussion of some of the most helpful research. There is then a list of the most important medical articles so that you can read further if you want to - most of this is freely available online, at least in summary form. A few notes on the individual sections: 1. This section covers key concepts relevant to vascular access and focusses on access type selection, including a historical introduction and review of the key literature informing our understanding. This explains why we are moving away from the outdated advice in previous guidelines (e.g. that 'all patients should dialyse with a fistula as first choice') towards a process which treats dialysis access selection as a choice, respecting patient individuality, aiming to provide high quality assessment and advice, so that patients are supported in making informed decisions. The basic concept of the fistula as optimal access is highlighted and remains valid, but it is placed within a more modern concept of care, in which the patient is at the centre of the decision process. 2. This section addresses the initial planning of access, from education and vein preservation, through to the timing of assessment and access formation, emphasising in particular the need to plan ahead. 3. This section deals with the formation and routine care of AV access (fistulas and grafts), covering access type and configuration, surgical and anaesthetic technique, the maturation period (before a fistula is ready to be used), and initiation and maintenance of optimal cannulation (needling). 4. This section deals with some of the complications of AV access. Research in this area is ongoing and not yet sufficient to give clear guidance, so we emphasise again the importance of involving patients in treatment decisions. 5. This section deals with the placement and routine care of catheter access (lines), covering location, technique, anticoagulant locks, and regular exit site disinfection and dressings. 6.
