Is this the end of the era of PLEX, and the beginning of the era of safely using lower dose of steroids in AAV? Results did not show a benefit of PLEX on the primary composite outcome of death and ESKD (hazard ratio 0.86, 95% CI: 0.65-1.13) after a median follow-up of 2.9 years (Walsh et al, NEJM 2020). PLEX requires central venous access (itself associated with the risk of bleeding and infection) and requires specialized staff and equipment. Google Scholar. #PexivasPolice will fine you Reduced dose steroids win, and PLEX loses. Similarly, nothing in terms of differences for the secondary outcomes: sustained remission, ESKD, death (separately considered) or the safety outcomes. 1/ A nephrologist's retrospective This is the result! CKD progres, Visual Abstract on ANCA vasculitis and Myeloperoxidase Inhibition Attenuates Neutrophil Activation. de Lind van Wijngaarden, R. A. et al.

Let PEXIVAS show you the path to less steroids and the end of plasma exchange, Looking forward to the next NephJC discussion for the NOSTONE trial in 2 weeks, Dont forget to sign up for NephJC newsletter. Everyone got induction with either cyclophosphamide or rituximab (per centre/treating physician choice) and steroids. After three months, the men taking a 30-milligram dose of dapoxetine took an average 2.78 minutes to ejaculate after penetration, those on a 60-milligram dose took 3.32 minutes. This page contains specific information for Viagra, not Revatio. MMF vs SC group had significant reduction in annual rate of eGFR decline (from, T2b Primary outcomes by subgroups Gauging the cost-effectiveness of this treatment modality, the potential short-term effect on risk reduction for ESKD, and the complex trade-off for the risk of infections should form the basis of shared decision-making with patients and their caregivers. Samira Farouk, MD, MS, FASN Here is where people might be most reluctant to let go of PLEX. This week the #NephJC chat will focus on the most recently published systematic review and meta-analysis of the effects of PLEX in patients with AAV (Walsh et al, BMJ 2022). N. Engl. Careers. As planned, the investigators recruited 704 patients, all of whom were included in the intention to treat analysis. Could the HR of about 0.64 mean there is a benefit in patients with pulmonary hemorrhage, but the trial was not powered to show this? The randomization was performed with the use of a minimization algorithm, with stratification according to age, kidney function, ANCA subtype, severity of pulmonary hemorrhage and planned type of induction immunosuppressive therapy. It was also evident from the tweetchat that the histological scoring systems for AAV (Brix score, Mayo clinic, or Napumpujte ho antioxidantmi a vitamnmi! Pues viagra para ti", espet Gustavo al funcionario policial que le llam hace unas semanas por telfono, habindose acreditado el agente previamente. showed improved renal survival at 1 and 5 years in patients with AAV who received PLEX compared to those who did not (p<0.01 in patients with initial SCr >250 umol/l [2.8 mg/dl]), with no difference in morbidity or mortality between the two groups (Szpirt et al, NDT 2011) - but the n was just 32. New or relapsing AAV (either GPA: granulomatosis with polyangiitis or MPA: microscopic polyangiitis), Positive MPO or PR3 antibodies (by ELISA), Kidney involvement (with an estimated glomerular filtration rate of less than 50 ml/min/1.73m^2), This could be on basis of kidney biopsy OR, OR pulmonary involvement (with diffuse alveolar hemorrhage), Use of PLEX, rituximab, cyclophosphamide or dialysis in the few days to weeks prior. Plasma exchange was ordered as 7 sessions in the first 14 days. The abstract was released nearly a year ago. In the meantime, to ensure continued support, we are displaying the site without styles But are we ready to accept the lack of benefit with no PLEX? The current evidence does not demonstrate a role for PLEX in addition to standard care with glucocorticoids and immunosuppressive therapies in preventing death in AAV. From their calculation of event rates, they planned to randomize 700 patients to gather data on 164 primary outcome events, which would give them 80% power. After 3 to 6 months of cyclophosphamide treatment, patients received azathioprine to maintain remission until at least week 52, after which time the local investigators took over. and JavaScript. Based on this review, the BMJ guideline panel recommends against the use of PLEX in patients with low or low-moderate risk of developing ESKD (i.e. ANCA-associated vasculitis (AAV) is now defined as a pauci-immune necrotizing vasculitis of predominantly small blood vessels that is associated with myeloperoxidase (MPO-ANCA), proteinase 3 (PR3-ANCA) positivity. Role of therapeutic plasmapheresis in ANCA-associated vasculitis. So it is unclear how big a deal this is. They make a weak recommendation in favor of PLEX in patients with moderate-high or high risk of progressing to ESKD (i.e. All-cause mortalityPLEX in all likelihood did not show any effect on all-cause mortality. Subsequently, the MEPEX (Jayne et al, JASN 2007) trial demonstrated that dialysis independence at 3 months was higher in the patient cohort that received PLEX compared to those who received intravenous (IV) methylprednisolone alone (they recruited 137 patients across 9 European countries with AAV and serum creatinine (SCr) >500 umol/l [5.7 mg/dl]. Smoothie. Additionally, between 25 and 50% of patients with severe AAV experience a severe infection within the first 12 months of treatment and the most frequently cited causes of death are infection or uncontrolled vasculitis. 2016 Feb;31(2):217-25. doi: 10.1007/s00467-014-3038-6. Effect of PLEX on risk of serious infections at 12 months follow up in patients with AAV (from Walsh et al, BMJ 2022). PMC Does this systematic review and meta-analysis herald the end of an era for PLEX or has this perPLEXed you further? T3c The study strengths include the population of IgAN at risk of progression, optimized SC for everyone, the avail, T3b What about the infection risk? Nine randomized controlled trials were included in the meta-analysis which included data from 1060 patients with a median follow-up of three years, as depicted in Figure 1.

In 2009, the CYCLOPS trial compared the effectiveness of oral versus intravenous (IV) CYC induction. Ron Falk and his irresponsible editorial. The subgroup analyses for the steroids also are quite similar. Epub 2017 Jun 7. Moreover, the win for reduced dose steroids is also quite clear, being clearly non-inferior as well as with less risk of severe infections. CKD progres, Plasma exchange and glucocorticoid dosing for patients with ANCA-associated vasculitis BMJ Rapid Recommendations Group, Walters et al (Cochrane Database Syst Rev 2020, Join #NephJC and the rest of #NephTwitter for a meet-up at NKF Spring Clinicals, Induction for AAV - It's ComPLEX the Visual Abstract, The ANCA PLEX commentary on Kidney Medicine. June 2018. more severe disease with SCr >300umo/l or needing dialysis). Will the potentially surprising conclusions from this systematic review overturn some of the recent pessimism the renal community has felt about the use of PLEX in this dreadful medical condition? This was assessed using the GRADE approach (i.e., the certainty of a minimal important effect being present). Some may ask if we even need to talk about PLEX in AAV again, particularly after the recently published PEXIVAS (Walsh et al, NEJM 2020) trial divided the nephrology community into two camps (to PLEX or not to PLEX). The CYCAZAREM trial in 2003 showed CYC could be safely transitioned to azathioprine (AZA) for maintenance. Do you think these results are generalizable? This site needs JavaScript to work properly. https://doi.org/10.3899/jrheum.190019 (2019). T3e Further limitations: open-label, excluded nephrotic range proteinuria and crescentic IgAN Refers to Walsh, M. et al. Landmark Nephrology is an online learning tool designed to collect landmark trials in nephrology and distribute content that makes learning nephrology fun and easy. Evolution of Therapy: Soon after steroids were discovered and made available for pharmaceutical use in the 1950s, they were utilized in vasculitis (ANCA were described much later, in the early 1980s). Longer-term follow-up in 1028 patients in eight trials: RR 0.93, 95%CI: 0.73 to 1.19, moderate certainty. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); document.getElementById( "ak_js_2" ).setAttribute( "value", ( new Date() ).getTime() ); Great post Dr Farkas, but needs to be updated now that PEXIVAS has now been published Feb 2020: https://www.nejm.org/doi/10.1056/NEJMoa1803537. During the second international ANCA workshop, the term peri-nuclear ANCA (p-ANCA) was accepted and soon after, ANCA serum antibodies assay were used as a diagnostic tool in ANCA glomerulonephritis. In keeping with the conclusions from the previously-published abstract, unless you *strongly* believed in PLEX for haemorrhaging ANCA-vasculitis. 2022 from, PREDNOS: Sixteen-week versus standard eight-week prednisolone therapy for childhood nephrotic syndrome ca. While none of the trials were blinded, given the objective nature of the outcomes (death, ESKD, and serious infections defined as need for hospitalization or IV antibiotics) that are unlikely to be affected by observation bias, the risk of bias was considered low for all studies. 2023 Apr;19(4):417-430. doi: 10.1080/1744666X.2023.2184354. The study will study 500 patients with ANCA-associated vasculitis with granulomatosis (Wegeners) or microscopic polyangiitis and test the usefulness of plasma exchange for the treatment of vasculitis. Weiner, M. et al. Freely Filtered, a NephJC Podcast Freely Filtered 012 PEXIVAS. This systematic review may help clinicians counsel patients with AAV across a range of baseline risks and inform shared decision-making with patients and their caregivers. There is no effect of PLEX on all-cause mortality in patients with or without pulmonary alveolar hemorrhage. Age-adjusted HR results in statistically significant results for primary outcome, but was not . Though there was no effect of PLEX on the primary outcome in the whole study population, the authors suggested a certain subset of patients might benefit from PLEX based upon the risk scores determined by baseline kidney function and histopathology.

Figure 5: Classification/scoring of kidney involvement in AAV (from Kronbichler, et al KI 2018), A recent retrospective study by Nezam et al. There are a lot of fads, blogs and strong opinions, but then theres SCIENCE. How big is the problem? It is important to note that there were some fundamental differences between the MEPEX and PEXIVAS trials (broader inclusion parameters and the lack of mandatory biopsy at baseline in the latter). Week 22 - 52: both groups were on 5 mg prednisone, after which it was in hands of local investigators. In a recent editorial, lead author Michael Walsh suggested that the beneficial effect of PLEX in AAV depends on the extent of renal involvement (Walsh, JASN 2022). Elinor Mannon (2022-2024), RFN Faculty Lead is supported by a Cupid Discovery grant and Gorski funds. This was chosen by the BMJ Rapid Recommendations group including absolute risk differences of 2% for mortality, 3% for ESKD, and 5% for serious infections. Even in MEPEX, and the last SR, the benefit for ESKD was more pronounced than the benefit for ESKD/death. Lets start with cyclophosphamide and glucocorticoids: Starting in the 1970s, cyclophosphamide (CYC) and glucocorticoids were found to be effective in ANCA vasculitis. PEXIVAS will enroll 500 patients (adults, and adolescents aged between 15-18 years) with ANCA-associated vasculitis affecting their kidneys and/or lungs. J. Rheumatol. Commonly used thresholds were used for HRQoL instruments. official website and that any information you provide is encrypted Many etiologies can cause diffuse alveolar hemorrhage, with pulmonary vasculitis being perhaps the most widely feared.
