Among them, 14 (66.7%) were diagnosed with MCD, 5 (23.8%) with FSGS, in 2 cases kidney biopsies were not performed. Median age was 54.6 years. Median follow up was 39.6 months. Number of relapses decreased significantly after Rituximab compared to before treatment (median relapses 0 compared to 3, respectively, W = 3.70, p <.001). Time to first relapse was significantly shorter before Rituximab compared to after (median 11 vs. 536 days, respectively, W = 3.05, p =.002). Hazzard Ratio for relapse was higher in patients who received one Rituximab course compared to those who received an additional maintenance (HR = 4.31, 95% CI: 1.13-16.39, p =.032). Treatment was well-tolerated, serious adverse events included cholecystitis and severe COVID-19.</p><p><strong>Conclusions: </strong>Rituximab emerges as an efficient safe steroid sparing in patients with SD/FR NS, with longer remission achieved when an additional maintenance dose is given after the first course.</p>","PeriodicalId":9089,"journal":{"name":"BMC Nephrology","volume":"26 1","pages":"126"},"PeriodicalIF":2.2,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11887153/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571698","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}

Little published data exists to establish current practice and there is no national guidance regarding TDC removal in United Kingdom (UK). Anecdotally, trainees suggest they do not have sufficient supervised training in TDC removal. We aimed to establish the differences in training and practice in TDC removal among nephrology trainees across UK.</p><p><strong>Method: </strong>We created an online survey with twenty questions for trainee and non-training nephrology registrars working in UK. The survey was distributed via regional renal training programme directors, UK Kidney Association, \"Renal SpR Club\" and online professional social networks including social media and instant messaging services.</p><p><strong>Results: </strong>We received 75 responses from all of 14 postgraduate training deaneries. 91% reported renal registrars remove TDCs in their units. 53% of the operators were taught by another registrar. Only 16% report awareness of written local trust guidance on TDC removal. 43% reported removing > 10 TDCs a year. Cut-down method is preferred over traction method for TDC removal. 63% remove TDCs in designated procedure areas, 52% obtain written consent and 65% wear full sterile personal protective equipment (PPE). 16% report removing TDCs alone with no assistant and 12% do not stop aspirin, antiplatelets or anticoagulants beforehand. 30% of operators reported experiencing a \"stuck catheter\" at some point in their careers.</p><p><strong>Conclusions: </strong>This survey highlights that TDC removal is a common procedure and predominantly performed by renal physicians in teaching hospitals. It is mostly undertaken by registrar level doctors often without formal training or written guidelines with varying techniques. 68% of participants want this procedure to be part of mandatory training in the renal post graduate training curriculum.</p><p><strong>Trial registration: </strong>Not applicable.</p>","PeriodicalId":9089,"journal":{"name":"BMC Nephrology","volume":"26 1","pages":"124"},"PeriodicalIF":2.2,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11887321/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143572079","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}
