Hence the study was designed to demonstrate the prevalence of serum anti-PLA2R levels and PLA2R staining in glomeruli in PMN and the clinical implications of the two parameters. <b>Objectives.</b> Investigate the prevalence of anti PLA2R positivity in PMN. Ascertain correlation between serum anti-PLA2R levels and glomerular staining for PLA2R with clinical and lab parameters in PMN. <b>Patients and Methods.</b> Fifty PMN patients during the period from October 2017 to December 2018 were included. Labs were done and eGFR was calculated as per MDRD 6. Anti-PLA2R titres were done in all patients. Titres more than 20 RU/ml were considered positive. Glomerular staining for PLA2R was graded on fresh frozen tissue by immunofluorescence technique. <b>Results.</b> Anti-PLA2R antibody positivity and glomerular PLA2R deposition was observed in 42% (21/50) and 86% (43/50) patients respectively. 79.3% (23/29) had positive glomerular PLA2R deposition with negative serum anti PLA2R. Positive correlation were observed between serum PLA2R antibody and serum creatinine (p = 0.0001) and urine protein-creatinine ratio levels with tissue PLA2R staining grades (p = 0.04). Negative association was found between serum albumin (p = 0.026) and tissue PLA2R staining grades. <b>Conclusion.</b> Serum anti-PLA2R wasn't a sensitive marker of primary membranous nephropathy in our study group emphasising the need to consider a compendium of serological markers for diagnosis of primary membranous nephropathy and to rely more on glomerular deposition of PLA2R as a better clinical indicator for PMN.</p>","PeriodicalId":12553,"journal":{"name":"Giornale italiano di nefrologia : organo ufficiale della Societa italiana di nefrologia","volume":"41 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140858273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nephrologist's opinion is that peritoneal dialysis is less used than it shold be. In Italy, PD is not carried out in private Centers, but neither is it in around one third of Public Centers. The aim of this study was to investigate the opinions of nephrologists on PD in Public Centers only, thereby nullifying the influence of the economic factors. <b>Materials and Methods.</b> The investigation was carried out by means of an online questionnaire (Qs) via mail, and during meetings and Congresses in 2006-07. The Qs investigated the characteristics of the Centers, the nephrologists interviewed, and opinions on the various aspects of the choice of Renal Replacement Therapy Renal Replacement Therapy (RRT) (26 questions). Responses were received from 454 nephrologists in 270 public Centers. Among these, 205 centers (370 Qs) report PD (PD-YES), 36 (42 Qs) do not (PD-NO) and 29 (42 Qs) do not use it but send patients selected for PD to other Centers (PD-TRANSF). <b>Results.</b> The PD-NO and PD-TRANSF Centers are significantly smaller, with greater availability of beds. In the PD-YES Centers the presence of a pre-dialysis pathway, early referral and nurses dedicated solely to PD are associated with a higher use of PD. The nephrologists in the PD-NO Centers rate PD more negatively in terms of both clinical and non-clinical factors.

Likewise, the belief that PD can be used as a first treatment in more than 30% of cases differs among the nephrologists in PD-YES (49.2%), PD-TRANSF (33.3%) and PD-NO (14.3%) Centers. <b>Conclusions.</b> The use of PD in Public Centers is conditioned by both structural and organizational factors, and by the opinions of nephrologists on the use and effectiveness of the technique.</p>","PeriodicalId":12553,"journal":{"name":"Giornale italiano di nefrologia : organo ufficiale della Societa italiana di nefrologia","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139996113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ACP is an important part of the therapeutic relationship between patients and doctors: thanks to ACP patients can think and discuss about end of life decisions, considering clinical aspects, but also psychological, cultural, social and ethical issues. Patients prepare themselves in advance because of the possibility of future cognitive impairment, can identify a surrogate decision maker and make end-life decisions according to their goals and values. End-stage kidney disease (ESRD) is often characterized by important symptoms, psychological suffering and social disadvantage, and patients affected by ESRD often have slow physical and cognitive decline. Despite this, access to palliative care is reduced for these patients as compared to patients affected by other end-stage organ failures. This is the reason why we want to explore the possibility of applying APC to ESRD patients. This pilot study, regarding three patients from the Dialysis Unit of ASST Crema in Italy, has been conducted to verify the applicability of the law 219/2017 in Dialysis Units. It shows that we have to deeply investigate this issue from both sanitary workers' and patients' and families' points of view. We need more studies with a larger number of patients and a longer period of follow-up, but we also need to teach sanitary workers how to approach APC and to teach people what APC is and why it's so important for everyone.</p>","PeriodicalId":12553,"journal":{"name":"Giornale italiano di nefrologia : organo ufficiale della Societa italiana di nefrologia","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139996103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The choice of technique cannot be based on the desired plasma bilirubin concentration, since these three techniques show similar results with a similar final outcome (exitus). In fact, PAP, PEX and MARS significantly reduce bilirubin levels, but the degree of reduction is not different among the three. Furthermore, the three techniques do not differ in the rate of cholinesterase change, while less reduction of liver transaminases was found by using PAP. MARS should be preferred in the case of renal involvement (hepatorenal syndrome with hyperbilirubinemia). PAP has the advantage of being simple and inexpensive.
