The conventional course of treatment has traditionally used ESAs (erythropoiesis-stimulating agents) such as erythropoietin; however, more recent medications, such as Desidustat, a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI), may be more advantageous in terms of both efficacy and cost. In this study, CKD patients receiving hemodialysis are compared for efficacy, safety, and cost-effectiveness between Desidustat and erythropoietin treatment. <b>Methods.</b> This prospective, single-center, open-label study with parallel groups was carried out at Saveetha Institute of Medical Sciences in Chennai. A total of 60 patients with CKD on maintenance hemodialysis were randomized to receive either Desidustat (100 mg orally, 3 times a week) or Erythropoietin (subcutaneous injections) for 12 weeks. At baseline, four weeks, eight weeks, and 12 weeks, hemoglobin levels, biomarkers (TSAT, ferritin, and hepcidin), and status of physical and mental health had been noted. The key finding was the proportion of hemoglobin responders (defined as a rise from baseline of ≥1g/dL). Secondary outcomes included predictors of hemoglobin response, adverse effects, and cost-effectiveness. <b>Results.</b> The proportion of hemoglobin responders was 83.33% in the Desidustat compared to 73.33% in the Erythropoietin group (p = 0.530), indicating no significant difference in efficacy. Hemoglobin levels increased gradually in both groups over 12 weeks. Higher serum albumin (OR = 3.32, 95% CI: 1.54-7.16, p = 0.008) and lower iPTH levels (OR = 0.98, 95% CI: 0.97-0.99, p = 0.004) have been important indicators of hemoglobin response. Hepcidin levels decreased significantly in the Desidustat group in contrast to Erythropoietin (p = 0.038), suggesting improved iron metabolism with Desidustat. No significant differences were noted in TSAT or ferritin levels. Adverse effects were comparable between the groups, with similar hospitalization and infection rates. Desidustat demonstrated better cost-effectiveness, with a lower monthly cost compared to Erythropoietin. <b>Conclusions.</b> When treating anemia in individuals with CKD receiving hemodialysis, Desidustat is a safe and efficient substitute for erythropoietin, with the added advantage of cost-effectiveness. Serum albumin and iPTH were significant predictors of hemoglobin response. To validate these results larger multicentric studies are necessary.</p>","PeriodicalId":12553,"journal":{"name":"Giornale italiano di nefrologia : organo ufficiale della Societa italiana di nefrologia","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143536827","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}

They are only rarely pathogenic to humans. There have been few cases reported of human infections, and even fewer cases of peritonitis in peritoneal dialysis. However, there is a higher risk in immunocompromised individuals. These microorganisms have the ability to form biofilms, leading to catheter-related infections, and possess intrinsic antibiotic resistance properties that are not well understood, making it challenging to identify specific therapies. We present a clinical case of a 61-year-old man undergoing automated peritoneal dialysis (APD) for end-stage renal disease due to light chain deposition disease in multiple myeloma. He was admitted to our department just over a month after starting replacement therapy due to a positive combur test and turbid fluid. The subsequent diagnosis was polymicrobial peritonitis caused by R. radiobacter and A. xylosoxidans. Despite initial empirical intraperitoneal antibiotic therapy with cefazolin and tobramycin, the treatment was optimized by introducing cefepime both intravenously and intraperitoneally, but without significant improvement. Given the diagnosis of refractory polymicrobial peritonitis, removal of the peritoneal catheter was necessary, resulting in drop-out from peritoneal dialysis. Although the outcome was unfavorable for the dialytic method, the purpose of our case report is to describe the first Italian case of peritonitis in peritoneal dialysis caused by these atypical pathogens in an immunocompromised patient. We hope this information will assist clinicians in their practice, as the available literature helped us in our diagnostic and therapeutic approach for this patient.</p>","PeriodicalId":12553,"journal":{"name":"Giornale italiano di nefrologia : organo ufficiale della Societa italiana di nefrologia","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143536801","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}

Data were summarized as mean and standard deviation, median and interquartile range, or absolute number. Differences among groups were tested through the Mann-Whitney test or Pearson's Chi-Square. The associations between eGFR and each outcome was tested by Spearman's correlation test. All variables related to the outcomes (with p-value <0.1) were included in the multivariate models. Longitudinal analysis was performed using generalized estimated equations (GEE) for binary outcome and by Linear Mixed Models for continuous variables.

The global rise in the number of individuals affected by CKD is dependent on the ageing, as well as on the growing prevalence of obesity, diabetes and hypertension. The need for treatment strategies aimed at preventing the onset of CKD and slowing its progression has led to the implementation of combination therapy, consisting of a Renin-Angiotensin-Aldosterone System inhibitor (RAASi) and a sodium-glucose cotransporter-2 inhibitor (SGLT-2i), which has demonstrated efficacy in slowing CKD progression and reducing the occurrence of cardiovascular events. Updated guidelines recommend a tailored, multi-drug approach based on the residual cardiorenal risk of the individual patient. The KDIGO guidelines advocate for a stepwise approach in managing diabetes mellitus and CKD, with RAASi and SGLT-2i as first-line therapy, and GLP-1 receptor agonists (GLP-1 RA) and non-steroidal mineralocorticoid receptor antagonists (MRAs) as additional agents for further cardiorenal protection.

Perception and subjective experience of the disease can also vary significantly, affecting emotional well-being and quality of life. Pregnancy, for instance, represents a critical phase for women with ADPKD, requiring specialized monitoring and specific management to address potential complications.
