RESUMO
OBJECTIVE: To determine the prevalence of chronic kidney disease and associated risk factors in subjects over 60 years of age, as well as its staging by determining the glomerular filtration rate (GFR). DESIGN: Cross-sectional observational study. SETTING: Primary Health Care. PARTICIPANTS: Patients≥60 years of age who were seen in 40 Primary Health Care centres with serum creatinine measured in a central laboratory between January 1 and December 31, 2010. EXCLUSION CRITERIA: kidney transplant, home care. MAIN MEASURES: Social-demographic and anthropometric data, cardiovascular risk factors, and diseases established according to electronic clinical records. Serum creatinine was measured using standardised Jaffe kinetic method, and GFR estimated with MDRD-4-IDMS and CKD-EPI. RESULTS: A total of 97,665 subjects (57.3% women, median age 70.0 years [Q1: 65.0, Q3: 77.0]). GFR-MDRD prevalence<60=15.1% (16.6% in women, 13.2% in men; P<.001) and increased with age. Multivariate analysis showed a positive association between GFR-MDRD<60 and age (OR=1.74; 95% CI 1.70 to 1.77), hypertension (OR=2.18; 95% CI 2.08 to 2.30), heart failure (OR=2.03; 95% CI 1.83 to 2.25), atrial fibrillation (OR=1.57; 95% CI 1.41 to 1.76), ischaemic heart disease (OR=1.40; 95% CI 1.30 to 1.50), peripheral arterial disease (OR=1.31; 95% CI 1.09 to 1.57), dyslipidaemia (OR=1.28; 95% CI 1.23 to 1.33), diabetes (OR=1.26; 95% CI 1.17 to 1.34), and stroke (OR=1.17; 95% CI 1.09 to 1.25). The GFR-CKD-EPI model showed an increase in OR with age and male sex, that became significant as a chronic kidney disease risk factor. CONCLUSIONS: Chronic kidney disease has considerable prevalence in subjects≥60 years seen in Primary Health Care, more in women, and increasing with age. Hypertension, more than diabetes, was the main associated cardiovascular risk factor.

Acquired perforating dermatosis (APD) is an uncommon disease characterized by lesions exhibiting transepidermal elimination of collagen or elastic fibers. APD affects adults and is associated with systemic diseases, mainly diabetes mellitus and renal failure. We present 8 cases of APD. Seven patients had concomitant diabetes mellitus with or without chronic renal failure, and 1 had alcoholic cirrhosis. In the patients with chronic renal failure, the onset of APD coincided with transient worsening of renal function. The mean increase in creatinine concentrations above baseline was 1.14mg/dL. Acute deterioration of renal function may be involved in APD. Further studies are needed to investigate this association.

OBJECTIVES: Evaluate associations between triceps braqui muscle ultrasound measures (TB US) and handgrip strength (HGS), and the sensibility of TB US for low HGS in non-dialysis-dependent chronic kidney disease (nd-CKD) patients. PARTICIPANTS AND METHODS: This pilot, cross-sectional, and exploratory study evaluated TB cross-sectional images from A-mode US and processed by FIJI-Image J to obtain muscle thickness (MT), echogenicity (EI), cross-sectional area (CSA), pennation angle (PA), and fascicle length (Lf) associating them with absolute HGS by simple and, multiple linear regression. The HGS was normalized to body mass index (BMI) and separated into low HGS (HGS/BMI≤10p according to sex and age) and adequate HGS (HGS/BMI>10p) groups. The body composition was from multifrequency bioimpedance. ROC analysis verified the TB US diagnostic accuracy to low HGS. RESULTS: Were included 42 (21M/21F) adults with 65.5 (60-70) y median age, 47.22% in 3b CKD stage. The low HGS group (45.23%) showed a higher fat mass (FM), TB muscle medium head's PA, and EI than adequate HGS (p<0.05). In crude model, a pixels increase in EI was associated with a 0.452kgf HGS reduction (p=0.019); adjusted for sex, age, and FM, a one-unit increase in EI was associated with a 0.510kgf HGS reduction (p=0.011). The EI also showed moderate diagnostic accuracy (AUC=0.730; CI 95%=0.589; 0.919) to low HGS and a sensitivity of 86.9% (cutoff≥13.52 pixels). CONCLUSION: In nd-CKD patients, of all measurements from US, the EI was the most associated with HGS, and the only one sensitive to low HGS diagnosis.

Chronic kidney disease (CKD) has severe consequences on the quality and expectancy of life and is considered a major health problem worldwide. This is, especially relevant in pediatric patients, as they have unique characteristics and a mortality rate 30 times higher (in advanced stages) than healthy people. This review aims to define the minimum components for the diagnostic approach and monitoring of CKD in the pediatric population from primary health care to promote comprehensive care and adequate risk management. For this purpose, we performed a systematic review of the literature with a panel of experts. Based on the evidence, to optimize the definition, diagnosis, and timely treatment of CKD in the pediatric population, we formulated 21 recommendations. These were approved by the research team and peer-reviewed by clinical experts. They will facilitate the definition of the diagnostic approach for CKD in the pediatric population in primary health-care settings, allowing for timely treatment intervention, comprehensive care, and monitoring of this disease.

Background: Chronic kidney disease (CKD) is a serious condition that impairs sleep quality, which compromises quality of life, cardiovascular function and increases the risk of mortality; however, limited information is available on sleep quality in hemodialysis (HD) patients. Objective: To determine the sleep quality in patients with CKD on renal replacement therapy with HD. Material and methods: Cross-sectional analytical study. The population included patients with CKD on HD, either sex, who answered the Pittsburgh questionnaire in a tertiary hospital. A 19-item self-administered survey was applied, assessing 7 components of sleep quality, where overall scores ≤ 5 and > 5 indicated respectively good and poor sleep quality. Socio-demographic, anthropometric, self-reported lifestyle and CKD history-related characteristics were assessed. Results: A total of 83 patients were included with a mean age of 45.3 (15.9), 63% (52) were male and 37% (31) female; of these, 63% (52) had poor sleep quality and 37% (31) had good sleep quality. Conclusion: Sleep quality is poor in patients with CKD on renal replacement therapy with HD. Variables influencing sleep quality are age, occupation, body mass index, sleep duration, and use of hypnotic medications. Therefore, HD patients should be evaluated to detect sleep problems in order to develop strategies to improve their sleep quality.
Introducción: la enfermedad renal crónica (ERC) es una condición grave que deteriora la calidad del sueño, lo que compromete la calidad de vida, la función cardiovascular y eleva el riesgo de mortalidad; sin embargo, es limitada la información disponible sobre la calidad del sueño en población con hemodiálisis (HD). Objetivo: determinar la calidad del sueño en los pacientes con ERC en terapia de sustitución renal con HD. Material y métodos: estudio transversal analítico. La población incluyó pacientes con ERC en HD, de cualquier sexo, que respondieron el Cuestionario de Pittsburgh en un hospital de tercer nivel. Se aplicó una encuesta autoadministrada de 19 elementos, que evalúa 7 componentes de la calidad del sueño. Los puntajes globales ≤ 5 y > 5 indicaron respectivamente una buena y mala calidad del sueño. Se evaluaron características sociodemográficas, antropométricas, el autorreporte de estilos de vida y las relacionadas con la historia de ERC. Resultados: se incluyeron un total de 83 pacientes con media de edad de 45.3 (15.9); 63% (52) fueron hombres y 37% (31) mujeres; de ellos, 63% (52) tuvieron mala calidad del sueño y 37% (31) tuvo buena calidad del sueño. Conclusión: la calidad del sueño es mala en los pacientes con ERC en terapia de sustitución renal con HD. Las variables que influyen en la calidad de sueño son la edad, ocupación, índice de masa corporal, duración del sueño y uso de medicamentos hipnóticos. Por tanto, los pacientes en HD deben ser evaluados para detectar problemas del sueño a fin de desarrollar estrategias para mejorar su calidad del sueño.

OBJECTIVE: Determinate instant and after 1-month non-dipper effect in hypertense patients after renal transplant by 24-hour ambulatory blood pressure monitoring in Hospital General de Zona No. 50, San Luis Potosí, Mexico. METHOD: Descriptive, longitudinal and prospective cohort study of a non-probability convenience sampling in post-transplant patients with hypertension. We collected data from MAPA and includes age, sex, cardiovascular risk factors in variables. Use of central tendency and dispersion measures for descriptive analysis and t Student for inferential analysis. RESULTS: 19 patients were included, 11 male (57.9%) and 8 females (42.1%), with age range 20 to 49 years (median of 30.2 years ± 7.7). Where the non-dipper effect in the first take was 89.5% and in the second take 84.2%. CONCLUSIONS: There is a high frequency of the non-dipper pattern in patients at one month of kidney transplant, the persistence of this hypertension may be, among others, by the use of immunosuppressants. A new category for non-dipper classification is described.

INTRODUCTION: Obesity is a major health problem worldwide. It carries a markedly increased risk for multiple diseases such as type 2 diabetes mellitus, hypertension, cardiovascular disease (CVD) and chronic kidney disease (CKD). To complicate an already difficult topic a new subtype of obesity has been defined lately, the metabolically healthy obese. Our study aimed to clarify the association between obesity, metabolic syndrome and kidney disease progression. METHODS: Observational retrospective single centre study including 212 patients with stage 3-4 CKD with no previous history of rapid kidney disease progression. Patients were divided according to BMI status and presence of metabolic syndrome. Anthropometric, clinical and laboratory data were collected to follow-up. Propensity score matching was performed for age, albuminuria and baseline renal function. During follow-up renal and cardiovascular events were recorded. RESULTS: After a mean follow-up of 88.44±36.07 months a total of 18 patients reached the renal outcome in the non-obese group and 21 in the obese group. Differences were not statistically significant (log rank=0.21: p=0.64). Multiple Cox regression analysis showed that obesity was not predictor for worse renal outcomes [HR 1.01, 95% CI 0.45-2.24; p=0.97]. When stratifying the sample according to baseline metabolic syndrome and obesity presence there was no difference in renal survival (log rank=0.852; p=0.35) A total of 48 cardiovascular events were registered: seventeen in the non-obese group and thirty-one in the obese group. Differences in event-free time between both groups were statistically significant (log rank=4.44;p=0.035), especially after four years of follow-up. After stratifying for MS and obesity presence at baseline the event-free time differences where again statistically significant (log rank=16.86;p=0.001), specially for the obese patients with metabolic syndrome. CONCLUSIONS: Obesity has little impact on chronic kidney disease progression despite the presence or absence of metabolic syndrome in a cohort matched for age, baseline renal function and albuminuria. Obesity conferred greater cardiovascular risk when combined with metabolic syndrome.

PURPOSE: To investigate the frequency of hypogonadism and its relationship to inflammation and carotid intima-media thickness (CIMT) in male patients with predialysis chronic kidney disease (CKD). METHODS: A total of 105 patients with CKD, 55 (52.4%) as stage 3, 33 (31.4%) as stage 4 and 17 (16.2%) as stage 5, were enrolled into the study. Total testosterone (TT) and free testosterone (FT), interleukin 6 (IL-6), C-reactive protein (CRP) levels, and CIMT were measured. RESULTS: According to TT and FT, hypogonadism was detected in 18 (17.1%) and 22 (20.9%) patients, respectively. There was no difference in terms of TT and FT, CIMT, CRP and IL-6 between the stages of CKD. According to TT, the patients with hypogonadism had significantly higher CRP and high-density lipoprotein cholesterol (HDL-cholesterol) levels (p=0.004 and p=0.005, respectively). There was no significant difference in other parameters. According to FT, the patients with hypogonadism had significantly higher CRP (p=0.017), and TT were negatively correlated with body mass index (BMI), waist circumference (WC), hip circumference, and CRP levels. FT was negatively correlated with age, waist circumference, systolic blood pressure, diastolic blood pressure (DBP) and CRP. CONCLUSIONS: The frequency of hypogonadism was found around 17-21% among the patients with CKD. Despite similar IL-6 and CIMT levels, CRP was found to be higher in the patients with hypogonadism. We consider that further studies with larger populations are needed to elucidate the entity.

INTRODUCTION AND OBJECTIVES: To analyze the evolution of kidney function after radical nephrectomy and to evaluate risk factors for adverse cardiovascular events during a long follow-up. MATERIAL AND METHODS: Retrospective study of patients submitted to radical nephrectomy due to renal cancer from January of 1996 to January of 2016. We evaluated their renal function after nephrectomy and during follow-up. We analyzed the possible predictive factors for adverse cardiovascular events with univariate and multivariate logistic regression analyses. RESULTS: There was an acute drop in glomerular filtration rate (GFR) after nephrectomy (21.2ml/min), which stabilized during follow-up in most cases. We evaluated the possible predictive factors for adverse cardiovascular events with logistic regression analyses, which presented previous cardiovascular disease (0,270, 95% CI 0,123-0,594, P<.001), diabetes (0,364, 95% CI 0,162-0,818 P=.015) and de novo hypertension (0,239, 95% CI 0,098-0,581, P=.002) as independently associated with the occurrence of adverse cardiovascular events. CONCLUSION: There was a deleterious effect in renal function after nephrectomy which remained stable during subsequent years in most patients. Approximately half of our patients had a GFR lower than 60mL/min after nephrectomy. Previous cardiovascular disease, diabetes and de novo hypertension were shown as risk factors for adverse cardiovascular events.

BACKGROUND: Controversy persists about the role of hepatitis C as a risk factor for developing kidney disease in the general population. Some authors have evaluated the effect of antiviral therapy for HCV on the risk of kidney disease. STUDY AIMS AND DESIGN: A systematic review of the published medical literature was performed to assess whether antiviral therapy for HCV has an independent impact on kidney survival in the adult general population. A random effects model was used to generate an overall estimate of the risk of kidney disease after anti-HCV therapy across the published studies. Meta-regression and stratified analysis were also carried out. RESULTS: Fifteen studies were eligible (n=356, 285 patients) and separate meta-analyses were conducted according to the outcome. Pooling studies based on viral responses (n=7; 34,763 individual patients) demonstrated a relationship between sustained viral response and lower frequency of kidney disease; the overall estimate for adjusted risk of kidney disease was 2.50 (95% CI, 1.41; 4.41) (p=0.0016) and between-study heterogeneity was found (p-value by Q test=0.004). Aggregation of studies comparing treated vs untreated cohorts (n=8, n=333,312 patients) revealed an association between anti-HCV therapy and lower risk of kidney disease. The overall estimate for adjusted risk of kidney disease across the eight studies was 0.39 (95% CI, 0.25; 0.612) (p=0.0001). Meta-regression showed that the effectiveness of antiviral therapy in reducing the frequency of kidney disease diminishes as cirrhosis (p=0.02) and HBV infection (p=0.0001) increase among HCV-infected individuals. CONCLUSIONS: Antiviral therapy for HCV lowers the risk of kidney disease among HCV-infected individuals. Studies to understand the mechanisms underlying this association are ongoing.

INTRODUCTION: Hyperkalemia (HK) is a common electrolyte disorder in chronic kidney disease (CKD), mainly in the advanced stages. A positive potassium balance due to reduced renal excretory capacity is likely the main pathogenic mechanism of HK. Research into the relative role of each pathogenic element in the development of HK in CKD may help to implement more suitable therapies. OBJECTIVE: To investigate renal potassium handling in advanced CKD patients, and to determine the differences between patients with or without HK. MATERIAL AND METHODS: Cross-sectional observational study in adult patients with stage 4-5 CKD pre-dialysis. Selection criteria included clinically stable patients and the ability to collect a 24hour urine sample correctly. Blood and urinary biochemical parameters were analysed including sodium and potassium (K). Fractional excretion of K (FEK) and K load relative to glomerular filtration (Ku/GFR) were calculated. HK was defined as a serum K concentration ≥5.5mmol/l. RESULTS: The study group consisted of 212 patients (mean age 65±14 years, 92 females) with a mean GFR of 15.0±4.2ml/min/1.73m2. 63 patients (30%) had HK. Patients with HK had lower mean bicarbonate levels with respect to patients with normal K levels (NK) (20.3±3.1 vs. 22.8±3.2 mEq/l, P<.0001), but no differences were noted in total urinary sodium and K excretion. While mean FEK values were lower in patients with HK (32.1±12.1% vs. 36.4±14.3%, P=.038), Ku/GFR values were significantly greater with respect to the NK subgroup (4.2±1.5 vs. 3.7±1.4 mmol/ml/min, P=0,049). FEK showed a strong linear correlation with Ku/GFR (R2=0.74), and partial linear regressions demonstrated that at a similar Ku/GFR level, the FEK of patients with HK was lower than that of NK patients. By multivariate linear and logistic regression analyses, both FEK and Ku/GFR were shown to be the main determinants of K serum levels and HK. CONCLUSIONS: Although the K load relative to glomerular filtration (Ku/GFR) is an important determinant of HK in advanced CKD, the most noteworthy characteristic associated with HK in these patients was the limitation of compensatory urinary K excretion, as indicated by lower FEK.

OBJECTIVE: To validate the content of the script of an educational video to promote self-care with arteriovenous fistula in chronic renal patients with nurses and social communicators. METHOD: Methodological study that constructed and validated an educational video. Firstly, the demands of self-care were identified through a literature review on self-care with arteriovenous fistula. Then the construction of the video followed the steps of pre-production, production and post-production. The script's content validation occurred in the pre-production phase and counted on 22 nursing judges and media professionals. The study was approved by the Ethics Committee in Research, under opinion 61705516.0.0000.5208. RESULTS: The following items received a negative evaluation from the judges: "The scenes described reflect stereotypes or discrimination" (p = 0.008) and "The pace of the scenes is tiring" (p = 0.001/p = 0.034), "The characters/images are appealing to the audience (p = 0.006), "The illustrations reflect important aspects of subject under study" (p = 0.006), "The illustrations promote the understanding of the video message" (p = 0.001) and "The general structure is creative" (p = 0.001). CONCLUSION: The educational video was considered valid by the nursing judges and media professionals to promote self-care with arteriovenous fistula among renal patients.

Abstract Objective To identify the prevalence of functional health literacy and analyze the association between functional health literacy levels and clinical and sociodemographic variables in non-dialysis chronic kidney disease patients. Methods This is a cross-sectional study carried out with 167 chronic kidney disease patients being monitored at the nephrology outpatient clinic of a large city in the state of Minas Gerais, Brazil. For the interviews, a sociodemographic and clinical questionnaire and the Brazilian version of the Short Assessment of Health Literacy for Portuguese Speaking Adults (SAHLPA-18) were used to measure functional health literacy. Descriptive statistics were performed for sociodemographic and clinical variables, and correlation tests and linear regression models for association with functional health literacy. Results Most participants were older adults with a median age of 68 years, 33.3% (56 patients) were in stage 3B of chronic kidney disease and 53.9% (90 patients) had inadequate functional health literacy. There was no association between functional health literacy levels and clinical variables. The majority reported not using the internet and the more advanced stage of chronic kidney disease had lower literacy scores. Worse functional health literacy scores were also identified in those with lower income. Conclusion Most participants had inadequate functional health literacy. Clinical variables were not predictors of literacy scores. However, lower health literacy scores were identified in those with more advanced stage kidney disease, lower income and less internet use.

Resultados. El estudio incluyó 7088 pacientes, la supervivencia a uno y cinco años fue del 79,5 % (IC 95 %: 78,6-80,5) y 50,6 % (IC 95 %: 49,1-52,1) respectivamente. La regresión de Cox para la edad de inicio de tratamiento resultó en un hazard ratio de 1,02 (IC 95 %: 1,01-1,02), mientras que para el oficio de ser agricultor el hazard ratio fue 1,1 (IC 95 %: 1,01-1,18) y para la etiología hipertensiva el hazard ratio fue de 0,7 (IC 95 %: 0,64-0,78). Conclusión. La edad de inicio de tratamiento y el ser agricultor están asociados con una menor supervivencia a cinco años en pacientes con diálisis
Introduction. The chronic kidney disease is responsible for approximately 2.4 million deaths worldwide, in El Salvador during 2019 death rate was 72.9 for 100 000 habitants, five year survival in patients after starting dialysis was between 39 and 60 % depending on the country. Objective. Analyze the factors that influence the five years survival in patients after starting renal replacement therapy in El Salvador. Methodology. It is a retrospective cohort study from patients included in dialysis and renal replacement therapy national registry from January 2016 to February 2023, the start point for the following was the initiation of dialysis, the event of interest was patient Ìs death, the Kaplan-Meier method was used to determine one year and five year survival; and Cox regression with Royston-Parmar model was used to analyze the factors that influence survival. Results. The study included 7088 patients, one and five-years survival was 79.5 % (CI 95 %: 78.6-80.5) and 50.6 % (CI 95 %: 49.1-52.1) respectively. The Cox regression for age of treatment initiation resulted in a hazard ratio of 1.02 (CI 95 %: 1.01-1.02), while for farmers, the hazard ratio was 1.09 (CI 95 %: 1.00-1.18), for hypertensive etiology the hazard ratio was 0.7 (CI 95 %: 0.64-0.78). Conclusion. Data suggest that age of treatment initiation, and jobs related to agriculture were associated with less five year survival in dialysis patients.

Introducción: la enfermedad renal crónica constituye un grave problema de salud pública mundial; en este sentido se hace necesario estar actualizado sobre los factores que influyen en la progresión de la enfermedad. Objetivos: caracterizar los factores de riesgo de progresión de la enfermedad renal crónica. Resultado: existen diversos factores que influyen en la progresión de la enfermedad renal crónica, dentro de los cuales se encuentran los no modificables (etiología de la enfermedad renal crónica, grado de función renal inicial, edad, sexo, raza, peso al nacimiento) y modificables (proteinuria, factores metabólicos, tabaquismo, obesidad, síndrome metabólico/ resistencia a la insulina, dislipidemias, anemia, empleo de sustancias nefrotóxicas). Conclusiones: se logró caracterizar un grupo de factores de riesgo que poseen gran influencia en el desarrollo de la enfermedad renal, cuya identificación temprana en los pacientes disminuirá la progresión a la enfermedad renal crónica, por lo que pueden ser utilizados como instrumentos de vigilancia clínica y epidemiológica.

Introduction: chronic kidney disease constitutes a serious global public health problem; in this sense, it is necessary to be updated on the factors that influence the progression of the disease. Objectives: to characterize the risk factors for progression of chronic kidney disease. Results: there are several factors that influence the progression of chronic kidney disease, among which are non-modifiable (etiology of chronic kidney disease, degree of initial renal function, age, sex, race, birth weight) and modifiable (proteinuria, metabolic factors, smoking, obesity, metabolic syndrome/insulin resistance, dyslipidemias, anemia, use of nephrotoxic substances). Conclusions: we were able to characterize a group of risk factors that have a great influence on the development of kidney disease, whose early identification in patients will reduce progression to chronic kidney disease, so they can be used as clinical and epidemiological surveillance tools.

RESUMO
Abstract Introduction: Cardiovascular disease is an important cause of death among patients with chronic kidney disease (CKD). Valve calcification is a predictor of cardiovascular mortality and coronary artery disease. Objective: To assess heart valve disease frequency, associated factors, and progression in CKD patients. Methods: We conducted a retrospective study on 291 CKD patients at Hospital das Clínicas de Pernambuco. Inclusion criteria were age ≥ 18 with CKD and valve disease, while those on conservative management or with missing data were excluded. Clinical and laboratory variables were compared, and patients were categorized by dialysis duration (<5 years; 5-10 years; >10 years). Statistical tests, including chi-square, Fisher's exact, ANOVA, and Kruskal-Wallis, were employed as needed. Simple and multivariate binary regression models were used to analyze valve disease associations with dialysis duration. Significance was defined as p < 0.05. Results: Mitral valve disease was present in 82.5% (240) of patients, followed by aortic valve disease (65.6%; 86). Over time, 106 (36.4%) patients developed valve disease. No significant association was found between aortic, pulmonary, mitral, or tricuspid valve disease and dialysis duration. Secondary hyperparathyroidism was the sole statistically significant factor for mitral valve disease in the regression model (OR 2.59 [95% CI: 1.09-6.18]; p = 0.031). Conclusion: CKD patients on renal replacement therapy exhibit a high frequency of valve disease, particularly mitral and aortic valve disease. However, no link was established between dialysis duration and valve disease occurrence or progression.
Resumo Introdução: Doenças cardiovasculares são uma causa significativa de morte em pacientes com Doença Renal Crônica (DRC). A calcificação valvar é preditor de mortalidade cardiovascular e doença arterial coronariana. Objetivo: Avaliar a frequência, fatores associados e progressão de valvopatias em pacientes com DRC. Métodos: Coorte retrospectiva com 291 pacientes ambulatoriais no Hospital das Clínicas de Pernambuco. Inclusão: ≥18 anos com DRC e valvopatia; exclusão: tratamento conservador ou dados incompletos. Variáveis clínicas e laboratoriais foram comparadas e categorizadas por tempo de terapia dialítica (TTD): <5 anos, 5-10 anos, >10 anos. Foram aplicados os testes Qui-quadrado, exato de Fisher, ANOVA, Kruskal-Wallis. Associação entre valvopatia e TTD foi avaliada por regressão binária. Significância foi definida como p < 0,05. Resultados: A valvopatia mitral foi encontrada em 82,5% (240) dos casos, seguida da aórtica (65,6%; 86). Houve progressão da doença valvar em 106 (36,4%) pacientes. Não houve associação entre valvopatias aórtica, pulmonar, mitral ou tricúspide e TTD. Hiperparatireoidismo secundário foi a única variável explicativa significativa na regressão para valvopatia mitral (OR 2,59 [IC95%: 1,09-6,18]; p = 0,031). Conclusão: Encontramos alta frequência de valvopatias, especialmente mitral e aórtica, aem pacientes com DRC. Não houve associação entre TTD e valvopatia.

Introduction: Individuals with chronic kidney disease may experience reduced quality of life associated with treatment costs. Objective: To evaluate health-related quality of life and its relationship with financial toxicity in individuals with chronic kidney disease undergoing hemodialysis treatment. Material and Methods: An observational, cross-sectional study involving 214 individuals was carried out, with data collected from February to May 2022 at four specialized dialysis clinics in the southern region of Brazil. Sociodemographic and clinical questionnaires, the Comprehensive Score for Financial Toxicity, and the Kidney Disease Quality of Life - Short Form were utilized. Descriptive analysis with absolute and relative frequencies was conducted for sociodemographic and clinical variables, and Pearson correlation was used for financial toxicity and health-related quality of life scores. Results: Four items of the Kidney Disease Quality of Life-Short Form questionnaire had an average score below 50, indicating poor quality of life: General health (10.75), Limitations in physical functioning (29.93), Burden of kidney disease (37.76), and Work status (39.49), with physical (34.49) and mental (49.19) composite scores. The relationship between financial toxicity and health-related quality of life revealed that a worse financial toxicity score was associated with a greater number of impaired dimensions. There was a significant correlation between financial toxicity, the mental health dimension, and the effects of kidney disease. Conclusion: Participants experienced compromised health-related quality of life, with a positive correlation with financial toxicity. (AU)

RESUMO
BACKGROUNDS AND PURPOSES: Patients with chronic kidney disease (CKD) have higher risk of developing cardiovascular disease. In CKD patients the mechanisms involved in, endothelial damage and the role of different drugs used on these patients are not completely understood. The aim of this work is to analyze the effect of statins and platelet antiaggregant (PA) on endothelial microvesicles (EMVs) and other markers of endothelial dysfunction. EXPERIMENTAL APPROACH: Cross-sectional study of 41 patients with CKD 3b-4 and 8 healthy volunteers. Circulating levels of EMVs, vascular endothelial growth factor (VEGF), and advance oxidized protein products (AOPPS) were quantified and the correlation with different comorbidity variables and therapeutic strategies were evaluated. RESULTS: EMVs are increased in CKD patients as compared with controls (171.1 vs. 68.3/µl, P<.001). It was observed a negative correlation between age and EMVs. Statins and PA were associated with a reduction in EMVs and VEGF levels, independently of the serum total cholesterol levels (TC). The levels of AOPPS and VEGF were not different in CKD vs. controls. CONCLUSION: CKD is associated with a change in EMVs, VEGF and AOPP levels. The treatment with statins and PA normalizes these values to almost the observed in controls and this effect is independently of the prevailing TC level. These findings explain the existence of the pleiotropic effects of statins and PA which deserve further studies.
