Abstract Introduction: The annual Brazilian Dialysis Survey (BDS) supports and contributes to the development of national health policies. Objective: To report 2023 epidemiological data from BDS Society Nephrology (BSN). Methods: A survey was carried out in a voluntary sample chronic dialysis centers using an online questionnaire covering clinical aspects patients on dialysis, characteristics centers. For estimates prevalence, incidence, source payment for were obtained random Results: total...
A new Chronic Kidney Disease Epidemiology Collaboration equation without the race variable has been recently proposed (CKD-EPIAS). This neither validated outside USA nor compared with European Function Consortium (EKFC) and Lund-Malmö Revised (LMREV) equations, developed in cohorts.Standardized creatinine measured glomerular filtration rate (GFR) from EKFC cohorts (n = 13 856 including 6031 individuals external validation cohort), France 4429, 964 Black Europeans), Brazil 100) Africa 508)...

Dengue is one of the most important mosquito-borne infections. Severe cases are more frequently observed in adults. However, 2008, State Rio de Janeiro, Brazil, experienced a severe dengue epidemic that primarily affected children and caused many hemorrhagic fever (DHF) death.A cross-sectional analytical study was conducted to examine laboratory diagnosis clinical epidemiologic factors for confirmed patients aged less than 16 years, from January June at municipal hospital City Brazil....
Stenosis resulting from neointimal hyperplasia remains a significant concern associated with dysfunction of arteriovenous fistulas (AVF). To investigate the safety and efficacy paclitaxel drug-coated balloon (DCB) angioplasty for treating failing AVFs. Investigators analyzed 58 hemodialysis patients treated RangerTM DCBs December 2022 to 2023 across four centers. Lesions were de novo or restenotic located in juxta-anastomosis, cannulation zone, outflow segment. Patients evaluated through...
Abstract Background: Data on parathyroid hormone (PTH) levels at hemodialysis (HD) initiation and during the first year of therapy are still scarce. We hypothesized that high baseline PTH contribute to more severe hyperparathyroidism this period. Methods: Incident HD patients (n = 1,973) were divided into 3 groups according values (<150, 150–600, > 600 pg/mL). Results: 1 273 (133–508) 255 (128–471) pg/mL, respectively (p 0.291). < 150, 150–600 >600 pg/mL found in 28.1, 53.5...
Resumo Histórico: Dados sobre os níveis de paratormônio (PTH) no início da hemodiálise (HD) e ao longo do primeiro ano terapia ainda são escassos. Nossa hipótese é que basais elevados PTH contribuem para um hiperparatireoidismo mais grave durante esse período. Métodos: Pacientes incidentes em HD (n = 1.973) foram divididos 3 grupos acordo com valores (<150, 150–600 >600 pg/mL). Resultados: Os estudo 273 (133–508) 255 (128–471) pg/mL, respectivamente (p 0,291). <150, pg/mL...
Background: Vascular stenosis commonly leads to dysfunction in hemodialysis vascular access. Although percutaneous transluminal angioplasty is an established treatment, stent utilization has increased the last decade as alternative solution extend access function. This study evaluated safety and initial results of a new impermeable covered for treating outflow stenosis. Methods: Investigators retrospectively analyzed 114 patients treated with polytetrafluorethylene-covered stents from...
Background . Glomerular filtration rate (GFR) is usually estimated from equations using serum creatinine (sCr), with adjustment for gender, age, and race (black or nonblack). The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) the preferred equation adults, but it was validated United States population. We intended to evaluate if race-ethnicity proposed sCr-based CKD-EPI appropriate Brazilian Methods CKD outpatients had blood samples collected determination of sCr cystatin C...
Background: Conflicting data regarding the incidence of hepatocellular carcinoma (HCC) after cure HCV infection with direct-acting antivirals (DAAs) remains. We investigated and risk factors to HCC treatment DAAs followed up for five years. Methods: A total 1075 patients ≥ 18 years were treated from 2015 2019 until 2022. Ultrasonography was performed before each 6 months thereafter. Results: Of total, 51/1075 (4.7%) developed in median 40 (IQR 25–58) months: 26/51 (51%) male, age 60 54–66)...
ABSTRACT Introduction: Brazil has the largest public and universal healthcare system in world, but little is known about outcomes of patients on hemodialysis (HD) country according to source funding for treatment. Objective: To compare profile survival under HD treatment funded by Public Healthcare System (SUS) those with private insurance. Methods: Retrospective analysis adults undergoing between 2012 2017 21 dialysis centers that provided both SUS health Participants, regardless paying...
Brazil has the third largest contingent of patients on maintenance hemodialysis (HD) worldwide. However, little is known regarding survival rate and predictors mortality risk in that population, which are purposes this study. A total 3,082 incident HD, from 2000 to 2004, at 25 dialysis facilities distributed among 7 out 26 states were followed-up until 2009. Patients 52 ± 16 years-old, 57.8% men, 20.4%, diabetics. The primary outcome was all causes mortality. Data censored five years...
Abstract Systemic anticoagulation with unfractionated heparin is commonly used in maintenance hemodialysis ( HD ), but it increases the risk of bleeding complications. We investigated whether use citrate‐enriched bicarbonate based dialysate CD ) would reduce systemic without compromising efficacy reprocessed dialyzers. This a crossover study which half total 30 patients initially underwent acetate‐enriched and standard dose ∼100 IU/kg (Treatment A whereas remaining were treated 30% reduced B...
Serum creatinine (sCr) is usually higher among black people in the United States due to increased muscle mass, justifying addition of race adjustment creatinine-based formulas estimate glomerular filtration rate (eGFR). We aimed assess if sCr levels are different low-income communities Brazil according their race. A total 1,303 participants were enrolled (58% females, 50±14 years-old, 33% self-defined as white, 41% mixed race, and 26% black). No significant differences found between racial...
Abstract Background and objectives High‐volume online hemodiafiltration (OL‐HDF) associates with improved outcomes compared to hemodialysis (HD), provided adequate dosing is achieved as estimated from convective volume (CV). Achievement of high CV its impact on biochemical indicators following a standardized protocol converting HD patients OL‐HDF has not been systematically reported. We assessed the success implementation in clinics naïve modality. Design, setting, participants, measurements...
Abstract Background Although Brazil has one of the largest populations on haemodialysis (HD) in world, data regarding patients’ characteristics and variables associated with risk death are scanty. Methods This is a retrospective analysis all adult patients who initiated maintenance HD at 23 dialysis centres between 2012 2017. Patients were censored after 60 months follow-up or end 2019. Results A total 5,081 included analysis. The median age was 59 years, 59.4% men, 37.5% had diabetes as...

Our aim was to analyze status end-stage renal disease (ESRD) management Portuguese-speaking Spanish-speaking countries America. Data were collected using a survey sent Society Nephrology each country, complemented with data available Latin American Dialysis Transplant Registry or personal communication collaborators within nephrology societies. Most have hybrid...
To evaluate the ability of different parameters exercise treadmill test to detect autonomic dysfunction in hemodialysis patients.
Abnormal ankle-brachial index (ABI) has been found to be a strong predictor of mortality in some hemodialysis populations studies with relatively short periods follow-up, lower than 2 years.This study aimed assess the predictive value abnormal ABI as risk factor for death among patients on maintenance after 5-year follow-up.A total 478 at least 12 months were included study. measurement was performed using mercury column sphygmomanometer and portable Doppler. Patients divided into 3 groups...

Abstract Background Fluid overload (FO) assessed by bioimpedance spectroscopy (BIS) is associated with higher mortality risk in maintenance haemodialysis (HD). The aim was to assess if a better management of FO through short daily (SDHD) could improve survival. Methods Retrospective analysis patients who were on HD 3 sessions/week for at least months and shifted in-centre SDHD (5 or 6 sessions/week, 2 h/session) between July 2012 June 2016 23 dialysis units Brazil. 12-month death analysed...
