Background: Recent guidelines recommend a target hemoglobin range of 11 to 12 g/dL in pediatric and adult dialysis patients. We compared anemia prevalence in United States Medicare pediatric and adult dialysis patients.
Methods: Prevalent hemodialysis patients (0 to 19 years, pediatric: N= 1692; adult: N= 352,291) and peritoneal dialysis patients (pediatric: N= 597; adult: N= 39,136) treated with recombinant human erythropoietin (rHuEPO) from 1996 to 2000 were selected. Mean annual hemoglobin values were calculated by modality, age, sex, and race.
Results: Among hemodialysis patients, mean annual hemoglobin values less than 11 g/dL were present in pediatric and adult patients during 54.1% versus 39.8% patient years, respectively (P < 0.0001); for peritoneal dialysis patients, 69.5% versus 55.1% (P < 0.0001). Mean hemoglobin values increased over time and were 11.2, 11.5, 10.8, and 11.2 g/dL for pediatric and adult hemodialysis and peritoneal dialysis patients, respectively, in 2000. Pediatric hemodialysis patients received intravenous iron less frequently than adults (66.3% vs. 82.5% patient years; P < 0.0001).
Conclusion: Hemoglobin values in rHuEPO-treated pediatric dialysis patients lagged behind those of adult patients, with pediatric patients achieving target hemoglobin values only a minority of the time (45.9% and 30.5% patient years, respectively, for hemodialysis and peritoneal dialysis). Trends show recent improvement in anemia treatment of children on dialysis. Still, further attention to and analysis of rHuEPO and iron therapy in pediatric dialysis patients is warranted.

Background: In an Italian cohort of lupus podocytopathy patients, we aimed to characterize the presenting features, therapy, and outcomes, and explore differences between relapsing and non-relapsing patients.
Methods: We identified 29 patients with lupus podocytopathy from 1994 to 2023 in 11 Italian Nephrology/Rheumatology Units, and divided them into two groups: relapsing and non-relapsing. Given the limited sample size, a p-value ≤ 0.
The impact of a secondary, rare, non-pathogenic PKD1 variant on disease progression in autosomal dominant polycystic kidney disease.
J Nephrol

Department of Nephrology, Beaumont Hospital, Dublin, Ireland.
Background: Autosomal dominant polycystic kidney disease (ADPKD) is caused primarily by pathogenic variants in the PKD1 and PKD2 genes. Although the type of ADPKD variant can influence disease severity, rare, hypomorphic PKD1 variants have also been reported to modify disease severity or cause biallelic ADPKD. This study examines whether rare, additional, potentially protein-altering, non-pathogenic PKD1 variants contribute to ADPKD phenotypic outcomes.

Patients with kidney failure require dialysis or kidney transplantation. Kidney transplantation offers great benefits, including reduced mortality; however, many patients who wish to undergo kidney transplantation are unable to do so due to a shortage of donor organs. This shortage is a global issue, and xenotransplantation has emerged as a potential solution.

Background: It remains unclear whether physicians should accept transplantation offers for candidates with a positive SARS-CoV-2 reverse transcription polymerase chain reaction test due to the potential risk of severe infection after initiating immunosuppressive therapy.
Methods: A multicenter observational study was conducted in 19 French solid organ transplantation units. Patients on the waiting list for liver or kidney transplants who had a positive SARS-CoV-2 reverse transcription polymerase chain reaction nasopharyngeal swab at the time of transplantation were recorded.
Sotalol poisoning and its unique treatment considerations compared with traditional therapies for beta-adrenoceptor blocking drug poisoning.
Clin Toxicol (Phila)
January 2025
Minnesota Regional Poison Center, Minneapolis, MN, USA.
Introduction: Sotalol is a beta-adrenoceptor blocking drug with unique physical and pharmacologic properties. Unlike most beta-adrenoceptor blocking drugs, sotalol is amenable to extracorporeal removal and causes QT interval prolongation and ventricular dysrhythmias. These properties have implications for treating sotalol poisoning.
