To perform adequate peritoneal dialysis, it is necessary to individualize the dialysis regimen. PD Adequest is a software program based on the three-pore model that can be used to predict solute clearance and ultrafiltration volume during peritoneal dialysis. We evaluated the ability of this program to predict the solute clearance and ultrafiltration volume in Japanese patients on peritoneal dialysis. The weekly creatinine clearance and weekly urea Kt/V were determined in 45 patients. The PD Adequest was used to simulate their current dialysis regimens and the predicted values of these parameters were calculated. Strong positive correlations were obtained between the actual and predicted weekly creatinine clearance (r = 0.993) and weekly urea Kt/V (r = 0.991). In conclusion, this program is potentially useful for designing peritoneal dialysis regimens in Japanese patients, even though they have a smaller body mass than Canadians and Americans for whom it was designed.

Department of Hemodialysis, Hospital General Regional No. 58, Mexican Institute of Social Security, León, Guanajuato, Mexico.
Background: Recent studies have demonstrated the effectiveness, safety, and tolerability of deferasirox in patients in peritoneal dialysis, however, its effect has not been studied in patients undergoing hemodialysis.
Objective: To investigate the impact of iron chelation on telomere length, oxidative stress, and ferritin levels in patients undergoing hemodialysis.
Methods: This is an open-label study, with a control group of patients undergoing hemodialysis, who will receive treatment with deferasirox 15mg/kg/day for 6 months for iron chelation.

Background: Protein-energy wasting (PEW) is the chronic kidney disease (CKD)-specific diagnosis encompassing malnutrition. PEW is associated with adverse outcomes, including those receiving peritoneal dialysis (PD). Identifying PEW requires accurate methods to improve diagnosis.

This case report presents a newborn with pyruvate dehydrogenase complex deficiency who developed significant lactic acidosis and acute kidney injury after birth. Peritoneal dialysis with glucose-based peritoneal dialysis fluid was initially started, but the patient had worsening hyperglycemia and lactic acidosis, likely related to excess glucose reabsorption with shunting to lactate due to the underlying metabolic disorder. As amino acid-based dialysis solution was not available in our formulary, a dialysis fluid was manually created with Vaminolact, which was commonly used in neonatal parenteral nutrition.

Introduction: The annual Brazilian Dialysis Survey (BDS) supports and contributes to the development of national health policies. Objective: To report the 2023 epidemiological data from the BDS of the Brazilian Society of Nephrology (BSN).
Methods: A survey was carried out in a voluntary sample of Brazilian chronic dialysis centers using an online questionnaire covering clinical and epidemiological aspects of patients on chronic dialysis, and characteristics of dialysis centers.
