Incremento del riesgo hemorrágico en pacientes con fibrilación auricular y enfermedad renal crónica en hemodiálisis tratados con anticoagulantes. Serie de cuatro centros / Increased risk of bleeding in patients with atrial fibrillation and chronic kidney disease on hemodialysis treated with anticoagulants. A four center series

Resumen Objetivo: El objetivo de este estudio fue estimar si el uso de anticoagulantes se asociaba con una diferencia en la frecuencia de trombosis de cualquier sitio, hemorragia mayor y mortalidad en adultos con coexistencia de ambas patologías. Método: Se realizó un estudio de cohorte retrospectivo en cuatro centros de alta complejidad. Se incluyeron mayores de 18 años con ERC en hemodiálisis y FA no valvular, con indicación de anticoagulación (CHA2DS2VASc ≥ 2). El desenlace primario fue la ocurrencia de sangrado mayor, evento trombótico (accidente vascular cerebral, infarto agudo al miocardio o enfermedad tromboembólica venosa) o muerte. Se realizó ajuste por variables de confusión por regresión logística. Resultados: De los 158 pacientes incluidos, el 61% (n = 97) recibieron anticoagulante. El desenlace principal se encontró en el 84% de quienes recibieron anticoagulación y en el 70% de quienes no la recibieron (OR: 2.12, IC95%: 0.98-4.57; luego del ajuste OR: 2.13, IC95%: 1.04-4.36). De los desenlaces mayores se presentaron sangrado en el 52% vs. el 34% (OR: 2.03; IC95%: 1.05-3.93), trombosis en el 35% vs. el 34% (OR: 1.03; IC95%: 0.52-2.01) y muerte en el 46% vs. el 41% (OR: 1.25; IC95%: 0.65-2.38). Conclusiones: Los resultados de este estudio sugieren un incremento en el riesgo de sangrado en los pacientes con FA y ERC en hemodiálisis que reciben anticoagulación, sin disminución del riesgo de eventos trombóticos ni de muerte.

Abstract Objective: The aim of this study was to estimate whether the consumption of anticoagulants was associated with a difference in the frequency of thrombosis of any site, major bleeding and mortality, in adults with both diseases. Method: A retrospective cohort study was carried out in four high complexity centers. Patients older than 18 years with CKD on hemodialysis and non-valvular AF, with an indication for anticoagulation (CHA2DS2VASc ≥ 2), were included. The primary outcome was the occurrence of: major bleeding, thrombotic event (cerebrovascular accident, acute myocardial infarction or venous thromboembolic disease) or death. Adjustment for confounding variables was performed using logistic regression. Results: From 158 patients included, 61% (n = 97) received an anticoagulant. The main outcome was found in 84% of those who received anticoagulation and 70% of those who did not (OR: 2.12, 95%CI: 0.98-4.57; after the adjusted analysis OR: 2.13, 95%CI: 1.04-4.36). Separate outcomes were bleeding in 52% vs. 34% (OR: 2.03; 95%CI: 1.05-3.93), thrombosis in 35% vs. 34% (OR: 1.03; 95%CI: 0.52-2-01) and death in 46% vs. 41% (OR: 1.25; 95%CI: 0.65-2.38). Conclusions: The results of this study suggest an increased risk of bleeding in patients with AF and CKD on hemodialysis receiving anticoagulation, without a decrease in the risk of thrombotic events or all-cause mortality.

Survival and its relationship with the type of peritoneal solute transfer rate, in patients with chronic kidney disease incident on peritoneal dialysis therapy in RTS Colombia between the years 2007-2017.

INTRODUCTION: In some studies, the peritoneal solute transfer rate (PSTR) through the peritoneal membrane has been related to an increased risk of mortality. It has been observed in the literature that those patients with rapid diffusion of solutes through the peritoneal membrane (high/fast transfer) and probably those with high average transfer characterized by the Peritoneal Equilibrium Test (PET) are associated with higher mortality compared to those patients who have a slow transfer rate. However, some authors have not documented this fact. In the present study, we want to evaluate the (etiological) relationship between the characteristics of peritoneal membrane transfer and mortality and survival of the technique in an incident population on peritoneal dialysis in RTS Colombia during the years 2007-2017 using a competing risk model. MATERIALS AND METHODS: A retrospective cohort study was carried out at RTS Colombia in the period between 2007 and 2017. In total, there were 8170 incident patients older than 18 years, who had a Peritoneal Equilibration Test (PET) between 28 and 180 days from the start of therapy. Demographic, clinical, and laboratory variables were evaluated. The (etiological) relationship between the type of peritoneal solute transfer rate at the start of therapy and overall mortality and technique survival were analyzed using a competing risk model (cause-specific proportional hazard model described by Royston-Lambert). RESULTS: Patients were classified into four categories based on the PET result: Slow/Low transfer (16.0%), low average (35.4%), high average (32.9%), and High/Fast transfer (15.7%). During follow-up, with a median of 730 days, 3025 (37.02%) patients died, 1079 (13.2%) were transferred to hemodialysis and 661 (8.1%) were transplanted. In the analysis of competing risks, adjusted for age, sex, presence of DM, HTA, body mass index, residual function, albumin, hemoglobin, phosphorus, and modality of PD at the start of therapy, we found cause-specific HR (HRce) for high/fast transfer was 1.13 (95% CI 0.98-1.30) p = 0.078, high average 1.08 (95% CI 0.96-1.22) p = 0.195, low average 1.09 (95% CI 0.96-1.22) p = 0.156 compared to the low/slow transfer rate. For technique survival, cause-specific HR for high/rapid transfer of 1.22 (95% CI 0.98-1.52) p = 0.66, high average HR was 1.10 (95% CI 0.91-1.33) p = 0.296, low average HR of 1.03 (95% CI 0.85-1.24) p = 0.733 compared with the low/slow transfer rate, adjusted for age, sex, DM, HTA, BMI, residual renal function, albumin, phosphorus, hemoglobin, and PD modality at start of therapy. Non-significant differences. CONCLUSIONS: When evaluating the etiological relationship between the type of peritoneal solute transfer rate and overall mortality and survival of the technique using a competing risk model, we found no etiological relationship between the characteristics of peritoneal membrane transfer according to the classification given by Twardowski assessed at the start of peritoneal dialysis therapy and overall mortality or technique survival in adjusted models. The analysis will then be made from the prognostic model with the purpose of predicting the risk of mortality and survival of the technique using the risk subdistribution model (Fine & Gray).

The urogenital microbiome in chronic kidney disease patients on peritoneal dialysis.

INTRODUCTION AND OBJECTIVES: Diabetes, dyslipidemia, older age, gender, urinary tract infections, and recent antibiotic intake have been associated with a decrease in the urobiome richness and other fluctuations in this microbiome. Gut and blood microbiome have been reported to be altered in patients with chronic kidney disease (CKD), and specifically in peritoneal dialysis (PD) patients. Still, there are currently no studies describing the urogenital microbiome in CKD-PD patients. In this study we characterized the urobiome profile in 46 PD patients and analyzed its clinical and inflammatory parameters. MATERIALS AND METHODS: Mid-stream urine, fecal and blood samples were collected from 46 patients undergoing PD at Centro Hospitalar Universitário de São João (CHUSJ) in Porto, Portugal. Exclusion criteria were age under 18 years old, inability to give informed consent, history of infection in the last three months, and antibiotic intake in the last three months. The microbiome communities were analyzed by amplification and sequencing of the V3-V4 region of the bacterial 16S rRNA gene. Correlations with the patients' clinical data and inflammatory profile were performed. RESULTS: CKD-PD patients presented a unique urobiome profile dominated by Bacillota, Actinomycetota and Pseudomonadota and characterized by a lower Shannon diversity than fecal and blood microbiome. The taxonomic profiles of urogenital samples were organized in multiple subtypes dominated by populations of Lactobacillus, Staphylococcus, Streptococcus, Gardnerella, Prevotella, Escherichia-Shigella, being similar to other non-PD-CKD patients. Gender, sCD14, residual diuresis and history of peritonitis were significantly associated to variations in the urobiome. Although not reaching statistical significance, diabetes and the time on PD also showed association with particular taxonomic groups. Depletion of Gardnerella, Staphylococcus, Corynebacterium, Lactobacillus or Dermabacter populations correlated with CKD-PD patients with history of diabetes, history of peritonitis and altered levels of sCD14. CONCLUSIONS: Our results highlight urogenital microbiome as a potential partner and/or marker in the overall health state of CKD-PD patients.

The efficacy of fluconazole for anti-fungal prophylaxis in peritoneal dialysis patients: A systematic review and meta-analysis.

INTRODUCTION AND OBJECTIVES: The efficacy of fluconazole as a prophylactic strategy in patients with chronic kidney disease (CKD) on peritoneal dialysis (PD) with prior antibiotic exposure is controversial in the current literature. This study aimed to compare a strategy of fluconazole prophylaxis versus no-prophylaxis for patients in PD on antibiotics for previous episodes of peritonitis. MATERIALS AND METHODS: We performed a systematic review and meta-analysis of observational studies and randomized controlled trials (RCTs) comparing fluconazole prophylaxis with no prophylaxis for PD-related peritonitis. The search was conducted on PubMed, EMBASE, and Cochrane Central in January 23, 2023. The outcome of interest was the occurrence of fungal peritonitis (FP). RESULTS: We included six studies (1 RCT, 5 observational) with 4515 occurrences of peritonitis, of which 1098 (24.8%) received fluconazole prophylaxis in variable doses, whereas 3417 (75.6%) did not receive prophylaxis during peritonitis episodes. Overall, fluconazole prophylaxis was associated with a lower incidence of FP (OR 0.22; 95% CI 0.12-0.41; p<0.001; I2=0%). Subgroup analysis of studies that administered daily doses of fluconazole also demonstrated a reduced incidence of FP in patients who received antifungal prophylaxis (OR 0.31; CI 0.14-0.69; p=0.004; I2=0%). CONCLUSIONS: In this meta-analysis of 4515 episodes of PD-related peritonitis, prophylaxis with fluconazole significantly reduced episodes of FP as compared with no antifungal prophylaxis.

Introducción y objetivos: La eficacia de fluconazol como estrategia profiláctica en los pacientes con enfermedad renal crónica (ERC) sometidos a diálisis peritoneal (DP) con exposición antibiótica previa es controvertida en la literatura actual. El objetivo de este estudio fue comparar la estrategia de profilaxis con fluconazol frente a no profilaxis para los pacientes de DP con régimen antibiótico por episodios previos de peritonitis. Materiales y métodos: Realizamos una revisión sistemática y metaanálisis de estudios observacionales y ensayos controlados aleatorizados (ECA), comparando la profilaxis con fluconazol y la no profilaxis para la peritonitis relacionada con DP. Dicha búsqueda se realizó en PubMed, EMBASE y Cochrane Central el 23 de enero de 2023. El resultado de interés fue la aparición de peritonitis fúngica (PF). Resultados: Incluimos seis estudios (1 ECA, 5 observacionales) con 4.515 episodios de peritonitis, de los cuales 1.098 (24,8%) recibieron profilaxis de fluconazol en dosis variables, mientras que 3.417 (75,6%) no recibieron profilaxis durante los episodios de peritonitis. En general, la profilaxis de fluconazol estuvo asociada a una menor incidencia de PF (OR: 0,22; IC 95%: 0,12-0,41; p<0,001; I2=0%). El análisis de subgrupo de los estudios que administraron dosis diarias de fluconazol también demostró una incidencia reducida de PF en los pacientes que recibieron profilaxis antifúngica (OR: 0,31; IC 95%: 0,14-0,69; p=0,004, I2=0%). Conclusiones: En este metaanálisis de 4.515 episodios de peritonitis relacionada con DP, la profilaxis con fluconazol redujo significativamente los episodios de PF, en comparación con la no profilaxis antifúngica.(AU)

Introducción y objetivos: Diabetes, dislipemia, edad avanzada, género, infecciones del tracto urinario y toma reciente de antibióticos, entre otras, se han asociado a una disminución en la riqueza del urobioma y a otras fluctuaciones de dicho microbioma.Recientemente, se han descrito alteraciones en losmicrobiomas intestinal y en sangreen pacientes con enfermedad renal crónica (ERC) y, específicamente, en pacientes en diálisis peritoneal (DP).A pesar de ello, aún no existen estudios que describan el microbioma urogenital en pacientes en DP. En el presente trabajo, caracterizamos el urobioma en 46 pacientes en DP. Pacientes y métodos: Se recogieron muestras de orina (micción espontánea), heces y sangre de 46 pacientes en DP del Centro HospitalarUniversitário de São João en Oporto, Portugal. Los criterios de exclusión fueron edad menor a 18 años, incapacidad para entenderel consentimiento informado, e historia de infección y toma de antibióticos en los últimos 3 meses. Las comunidades microbiológicas fueron analizadas por amplificación y secuenciación de las regiones V3-V4 del 16S rRNA bacteriano. Se realizaron correlaciones con los datos clínicos y el perfil inflamatorio de los pacientes. Resultados: Los pacientes en DP presentaron un urobioma único dominado por Bacillota, Actinomycetota yPseudomonadota, y caracterizado por una menor diversidad de Shannon que los microbiomas en sangre e intestinal. Los perfiles taxonómicos de las muestras urogenitales se organizaron en múltiples subtipos dominados por poblaciones de Lactobacillus, Staphylococcus, Streptococcus, Gardnerella, Prevotella, Escherichia-Shigella, siendo similar al descrito para otros pacientes con ERC no en DP.Género, factor sCD14, diuresis residual yantecedentes de peritonitis se asociaron de forma significativa a cambios en el urobioma...

Vascular calcification in peritoneal dialysis patients and its association with bone-derived molecules and bone histomorphometry / Calcificación vascular en pacientes en diálisis peritoneal y su asociación con moléculas derivadas de hueso e histomorfometría ósea

Introduction: Data regarding vascular calcification (VC) in contemporary peritoneal dialysis (PD) patients is scarce. Bone–vascular axis has been demonstrated in hemodialysis (HD). However, studies showing the link between bone disease and VC in PD patients are lacking. The role of sclerostin, dickkopf-related protein 1 (DKK-1), receptor activator for nuclear factor kB ligand and osteoprotegerin (OPG) in VC in PD remains to clarify. Materials and methods: Bone biopsy was performed in 47 prevalent PD patients with histomorphometric analysis. Patients were submitted to pelvis and hands X-ray to evaluate VC using the Adragão score (AS). Relevant clinical and biochemical data was collected. Results: Thirteen patients (27.7%) had positive AS (AS≥1). Patients with VC were significantly older (58.9 vs. 50.4 years, p=0.011), had a lower dialysis dose (KT/V 2.0 vs. 2.4, p=0.025) and a higher glycosylated hemoglobin (7.2 vs. 5.4%, p=0.001). There was not any laboratorial parameter of mineral and bone disease used in clinical practice different between patients with or without VC. All diabetic patients had VC but only 8.1% of non-diabetic had VC (p<0.001). Patients with VC showed significantly higher erythrocyte sedimentation rate (ESR) (91.1 vs. 60.0mm/h, p=0.001), sclerostin (2250.0 vs. 1745.8pg/mL, p=0.035), DKK-1 (1451.6 vs. 1042.9pg/mL, p=0.041) and OPG levels (2904.9 vs. 1518.2pg/mL, p=0.002). On multivariate analysis, only ESR remained statistically significant (OR 1.07; 95% CI 1.01–1.14; p=0.022). Bone histomorphometric findings were not different in patients with VC. There was no correlation between bone formation rate and AS (r=−0.039; p=0.796). Conclusion: The presence of VC was not associated with bone turnover and volume evaluated by bone histomorphometry. Inflammation and diabetes seem to play a more relevant role in VC in PD. (AU)

Introducción Los datos sobre calcificación vascular (CV) en pacientes contemporáneos en diálisis peritoneal (DP) son escasos. En pacientes en hemodiálisis, se ha demostrado la existencia de una conexión entre hueso y sistema vascular; sin embargo, faltan estudios que muestren el vínculo entre la enfermedad ósea y la CV en pacientes en DP. Si la esclerostina, la proteína relacionada con Dickkopf 1 (DKK-1), el ligando del receptor activador para el factor nuclear κB (RANKL) y la osteoprotegerina (OPG) tienen un papel en la CV en pacientes en DP aún no está claro. Materiales y métodos Se realizó biopsia ósea en 47 pacientes prevalentes en DP y se analizó mediante histomorfometría. También se tomaron radiografías de pelvis y manos a los pacientes para evaluar la CV mediante el Índice de Adragão (IA). Además, se analizaron datos clínicos y bioquímicos relevantes. Resultados: Trece pacientes (27,7%) tuvieron IA positivo (IA ≥ 1). Los pacientes con CV eran significativamente mayores (58,9 vs 50,4 años, p=0,011) tenían menor dosis de diálisis (KT/V 2,0 vs 2,4, p=0,025) y niveles más elevados de hemoglobina glicosilada (7,2 vs 5,4%, p=0,001). No hubo ningún parámetro de laboratorio de enfermedad mineral y ósea utilizado en la práctica clínica diferente entre pacientes con o sin CV. Todos los pacientes diabéticos mostraron CV, sin embargo, solo el 8,1% de los no diabéticos tenían CV (p <0,001). Además, los pacientes con CV mostraron una velocidad de sedimentación globular más elevada (VSG) (91,1 vs. 60,0mm/h, p=0,001) y mayores concentraciones séricas de esclerostina (2.250,0 vs. 1.745,8 pg/ml, p=0,035), DKK-1 (1451,6 vs 1042,9 pg/ml, p=0,041) y OPG (2.904,9 vs. 1.518,2 pg/ml, p=0,002). En el análisis multivariante, solo la VSG fue estadísticamente significativa (OR 1,07; IC del 95%: 1,01-1,14; p=0,022)... (AU)

Fibrilación auricular no valvular en pacientes en diálisis peritoneal: prevalencia, tratamiento y profesionales implicados / Non-valvular atrial fibrillation in patients on peritoneal dialysis: prevalence, treatment and professionals involved

La fibrilación auricular (FA) es la arritmia crónica más frecuente en pacientes con enfermedad renal crónica (ERC). La anticoagulación oral con antagonistas de la vitamina K (AVK) y actualmente los anticoagulantes orales de acción directa (ACOD) han sido el pilar fundamental para la prevención de eventos tromboembólicos. Sin embargo, no existen ensayos clínicos aleatorizados de su perfil riesgo-beneficio en pacientes con ERC estadio 5 en diálisis peritoneal (DP) y son pocas las evidencias en la literatura sobre esta población. El objetivo del estudio fue conocer la prevalencia, tratamiento y profesionales implicados en el manejo de la FA en DP en nuestro entorno mediante el análisis descriptivo de una encuesta enviada a diferentes unidades de DP de España. Se incluyeron en el estudio 1.403 pacientes en programa de DP, de los cuales 186 (13,2%) presentaban FA no valvular (FANV). Además, observamos que la valoración de los scores para el inicio del tratamiento anticoagulante la realizaba mayoritariamente el cardiólogo (60% de los centros), así como la prescripción de anticoagulación (cardiólogo 47% o en conjunto con el nefrólogo 43%). En conclusión, los pacientes en DP presentan una notable prevalencia de FANV. Reciben frecuentemente anticoagulación oral (ACO) con AVK, así como con ACOD. Los datos obtenidos respecto a las escalas utilizadas para la valoración de riesgo tromboembólico y de sangrado, tratamiento e implicación por parte de Nefrología indican que existe una necesidad de formación e involucramiento del nefrólogo en esta patología.(AU)

Atrial fibrillation is the most frequent chronic arrhythmia in patients with chronic kidney disease. Oral anticoagulation with vitamin K antagonists and now direct oral anticoagulants have been and are the fundamental pillar for the prevention of thromboembolic events. However, there are no randomized clinical trials on the risk-benefit profile of oral anticoagulation in patients with chronic kidney disease stage 5 on peritoneal dialysis and there is little evidence in the literature in this population. The objective of our study was to know the prevalence, treatment and professionals involved in the management of atrial fibrillation in peritoneal dialysis patients. For this purpose, we performed a descriptive analysis through a survey sent to different peritoneal dialysis units in Spain. A total of 1403 patients on peritoneal dialysis were included in the study, of whom 186 (13.2%) had non-valvular atrial fibrillation. In addition, the assessment of the scores of thromboembolic and bleeding risks for the indication of oral anticoagulation was mainly carried out by the cardiologist (60% of the units), as well as its prescription (cardiologist 47% in consensus with the nephrologist 43%). In summary, patients on peritoneal dialysis have a remarkable prevalence of non-valvular atrial fibrillation. Patients frequently receive oral anticoagulation with vitamin K antagonists, as well as direct oral anticoagulants. The data obtained regarding the scales used for the assessment of thromboembolic and bleeding risk, treatment and involvement by Nephrology indicates that there is a need for training and involvement of the nephrologist in this pathology.(AU)

FACTORS ASSOCIATED WITH ERC-5 IN PATIENTS OF AN EPS IN VALLE DEL CAUCA 2018-2020 / FACTORES ASOCIADOS A LA ERC-5 EN PACIENTES DE UNA EPS DEL VALLE DEL CAUCA 2018-2020

Introduction: Chronic Kidney Disease (CKD) involves a progressive deterioration in kidney function, affecting the ability to filter metabolic waste. Factors such as age, family history, ethnicity, sex, and unhealthy habits may contribute to progression to stage 5 (CKD-5). Methodology: Retrospective observational study analyzed patients with hypertension, diabetes, morbid obesity, dyslipidemia and CKD in Valle del Cauca from 2018 to 2020. Cases with CKD-5, previous dialysis, and significant changes were excluded. A census was used as a sampling method, consolidating quarterly data in 12 databases. The analysis addressed sociodemographic and clinical factors, evaluating associations with binary logistic regression, and the study was ethically approved. Results: In a cohort of 57,643 patients with CKD stages 1 to 4, the majority began follow-up in stages 2 and 3. The prevalent comorbidities were hypertension, overweight and obesity. The incidence of CKD-5 was 6 new cases per 1000 patients, being higher in the population aged 30 to 44 years, male, non-ethnic, not belonging to vulnerable groups and residing in certain municipalities. Factors such as uncontrolled blood pressure, lack of specific medication and follow-up in advanced renal stages were significantly associated with the incidence of CKD stage 5. In addition, a direct relationship was observed between the advancement of renal stage and the increase in creatinine in the blood, albumin in urine, total cholesterol and HDL cholesterol. Patients who advanced to stage 5 showed significantly higher levels of blood creatinine, albuminuria, total cholesterol, and LDL cholesterol compared to those who remained in stage 4 or lower.

Introducción: La Enfermedad Renal Crónica (ERC) implica un deterioro progresivo en la función renal, afectando la capacidad de filtrar desechos metabólicos. Factores como edad, antecedentes familiares, etnia, sexo, y hábitos poco saludables pueden contribuir a la progresión hacia el estadio 5 (ERC-5). Metodología: Estudio observacional retrospectivo analizó pacientes con hipertensión, diabetes, obesidad mórbida, dislipidemia y ERC en el Valle del Cauca de 2018 a 2020. Se excluyeron casos con ERC-5, diálisis previa, y cambios significativos. Se utilizó un censo como método de muestreo, consolidando datos trimestrales en 12 bases. El análisis abordó factores sociodemográficos y clínicos, evaluando asociaciones con regresión logística binaria, y el estudio fue éticamente aprobado. Resultados: En una cohorte de 57,643 pacientes con ERC estadios 1 a 4, la mayoría inició el seguimiento en estadios 2 y 3. Las comorbilidades prevalentes fueron hipertensión, sobrepeso y obesidad. La incidencia de ERC-5 fue de 6 casos nuevos por cada 1000 pacientes, siendo mayor en población de 30 a 44 años, sexo masculino, no étnica, no perteneciente a grupos vulnerables y residente en ciertos municipios. Factores como la presión arterial no controlada, falta de medicación específica y seguimiento en estadios renales avanzados se asociaron significativamente con la incidencia de ERC estadio 5. Además, se observó una relación directa entre el avance de estadio renal y el incremento de creatinina en sangre, albumina en orina, colesterol total y colesterol HDL. Los pacientes que avanzaron a estadio 5 mostraron niveles significativamente superiores de creatinina en sangre, albuminuria, colesterol total y colesterol LDL en comparación con los que permanecieron en fase 4 o inferior.

Alteraciones neuropsicológicas en pacientes en tratamiento con diálisis peritoneal / Neuropsychological impairments in patients undergoing peritoneal dialysis treatment

Objetivo: Los pacientes con enfermedad renal crónica (ERC) en hemodiálisis (HD) suelen presentar déficits cognitivos. Sin embargo, existen pocos estudios que hayan examinado el funcionamiento neuropsicológico de aquellos que reciben diálisis peritoneal (DP). Método: Se evaluaron las funciones ejecutivas, la velocidad de procesamiento y la memoria verbal en 27 pacientes en DP, 42 en HD y 42 participantes sanos (PS). La presión sanguínea sistólica y el tiempo total en terapia renal sustitutiva (TRS) se controlaron estadísticamente. Las asociaciones entre el rendimiento y los factores clínicos se analizaron mediante correlaciones y regresión múltiple. Resultados: El grupo DP presentó mejor ejecución respecto al HD en fluidez verbal, memoria de trabajo, flexibilidad cognitiva, planificación y toma de decisiones. El grupo DP mostró peor ejecución que el grupo PS en inhibición y memoria verbal. Las puntuaciones en las funciones ejecutivas se asociaron positivamente con los meses totales en DP, en TRS, en HD, la albúmina, el colesterol total y el fósforo, y de forma negativa con la ferritina. Conclusión: El funcionamiento ejecutivo global fue mejor en los pacientes en DP que en aquellos en HD. Los resultados muestran el efecto positivo de la DP sobre las funciones ejecutivas, lo que debe tenerse en cuenta a la hora de la elección de la TRS. Las asociaciones observadas entre los factores bioquímicos y el rendimiento muestran la importancia de mantener un adecuado estado nutricional en estos pacientes.(AU)

Background: Patients with chronic kidney disease on hemodialysis (HD) often have cognitive deficits. However, there are few studies that have examined the neuropsychological impairments of patients receiving peritoneal dialysis (PD). Methods: Executive functions, processing speed and verbal memory were assessed in 27 PD patients, 42 HD patients, and 42 healthy participants (HP). Systolic blood pressure and total time on renal replacement therapy (RRT) were controlled statistically. Associations between performance and clinical factors were analyzed using correlations and multiple regression. Results: The DP group showed better performance compared to the HD group in verbal fluency, working memory, cognitive flexibility, planning and decision making. The DP group showed worse execution than the HP group in verbal inhibition and memory. Executive function scores were positively associated with total months on PD, total months on RRT, total months on HD, albumin, total cholesterol, and phosphorus, and negatively with ferritin. Conclusion: Global executive functioning was more optimal in PD patients than in HD patients. The results show the positive effect of PD on executive functions, which must be taken into account when choosing the TRS. The associations observed between biochemical factors and performance show the importance of maintaining an adequate nutritional status in these patients.(AU)

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 ́s 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.

[Neuropsychological impairments in patients undergoing peritoneal dialysis treatment]. / Alteraciones neuropsicológicas en pacientes en tratamiento con diálisis peritoneal.

BACKGROUND: Patients with chronic kidney disease on hemodialysis (HD) often have cognitive deficits. However, there are few studies that have examined the neuropsychological impairments of patients receiving peritoneal dialysis (PD). METHODS: Executive functions, processing speed and verbal memory were assessed in 27 PD patients, 42 HD patients, and 42 healthy participants (HP). Systolic blood pressure and total time on renal replacement therapy (RRT) were controlled statistically. Associations between performance and clinical factors were analyzed using correlations and multiple regression. RESULTS: The DP group showed better performance compared to the HD group in verbal fluency, working memory, cognitive flexibility, planning and decision making. The DP group showed worse execution than the HP group in verbal inhibition and memory. Executive function scores were positively associated with total months on PD, total months on RRT, total months on HD, albumin, total cholesterol, and phosphorus, and negatively with ferritin. CONCLUSION: Global executive functioning was more optimal in PD patients than in HD patients. The results show the positive effect of PD on executive functions, which must be taken into account when choosing the TRS. The associations observed between biochemical factors and performance show the importance of maintaining an adequate nutritional status in these patients.

Fatores socioeconômicos, clínicos e nutricionais no ganho de peso interdialítico em usuários de hemodiálise / Factores socioeconómicos, clínicos y nutricionales en el aumento de peso interdialítico en usuarios de hemodiálisis / Socioeconomic, clinical and nutritional factors on interdialytic weight gain in haemodialysis users

Resumo Objetivo Avaliar os fatores associados ao ganho de peso interdialítico em usuários de serviços de hemodiálise em uma Região Metropolitana do Brasil. Métodos Estudo epidemiológico transversal envolvendo 1.024 indivíduos com doença renal crônica em hemodiálise no Brasil. O ganho de peso interdialítico foi avaliado pelo percentual de ganho de peso entre uma sessão de hemodiálise e outra. As variáveis incluídas na análise de regressão logística binária foram selecionadas considerando p< 0,10 no teste bivariado. Resultados Demonstramos que ter mais anos de estudo (OR=0,537;IC 95% = 0,310-0,931; p=0,027) e sobrepeso (OR=0,661;IC 95% = 0,461-0,948; p=0,024) ou obesidade ( OR=0,387;IC 95% = 0,246-0,608; p=<0,001) reduziu as chances de os usuários apresentarem alto ganho de peso interdialítico. Usuários sem trabalho remunerado (OR=2,025; IC 95% = 1,218-3,365; p=0,007) e que não adotavam medidas para reduzir o sal (OR=1,694; IC 95% = 1,085-2,645; p=0,020) tiveram maiores chances de ganho de peso interdialítico. Conclusão Os resultados apontam para associação entre o aumento do ganho de peso interdialítico e a ausência de trabalho remunerado e a não adoção de medidas para reduzir a ingestão de sal na dieta. Portanto, o conhecimento sobre esses fatores associados pode ser uma alternativa importante para o direcionamento individualizado dessa população.

Abstract Objectives The study aimed to evaluate the factors associated with interdialytic weight gain in users of haemodialysis services in a metropolitan region of Brazil. Methods This is an cross-sectional epidemiological study with 1,024 individuals with chronic kidney disease on haemodialysis in Brazil. Interdialytic weight gain was evaluated by the percentage weight gain between one haemodialysis session and another. The variables included in the binary logistic regression analysis were selected by considering p< 0.10 in the bivariate test. Results We demonstrated that having more years of study (OR=0.537;CI 95% = 0.310-0.931; p=0.027) and be overweight (OR=0.661;CI 95% = 0.461-0.948; p=0.024) or obese (OR=0.387;CI 95% = 0.246-0.608; p=<0.001) reduced the chances of users having high interdialytic weight gain. Those who did not have paid work (OR=2.025;CI 95% = 1.218-3.365; p=0.007) and not adopting measures to reduce salt increased (OR=1.694;CI 95% = 1.085-2.645; p=0.020) increased the chances of interdialytic weight. Conclusion The results point to an association between the increase in interdialytic weight gain and the absence of paid work and the non-adoption of measures to reduce salt intake in the diet. Therefore, the need for knowledge about these associated factors can be an important alternative for the individual targeting of this population.

The effect of non-compliance with diet and liquid restriction on fatigue in dialysis patients / O efeito da não aderência à dieta e restrição de líquidos sobre a fadiga em pacientes recebendo diálise / El efecto del incumplimiento de la dieta y la restricción de líquidos en la fatiga en pacientes en diálisis

ABSTRACT Objective: This study was conducted to determine the relationship between non-compliance with dietary and fluid restriction, body mass index, and the severity of fatigue in dialysis patients. Method: A descriptive and cross-sectional study was conducted on 42 dialysis patients. The data were collected employing a "General Information Form", Body Mass Index, "Fatigue Severity Scale", and "Dialysis Diet and Fluid Non-Adherence Questionnaire.". Data were evaluated using percentages, averages, one-way ANOVA, T-tests, and Pearson correlation tests. Results: The average number of days when the patients did not comply with their diet was 3.69 ± 4.85, and the average number of days when they did not comply with fluid restriction was 2.71 ± 5.02. The age and marital status of the patients were found to affect the fatigue severity. It was found that the cases were associated with creatinine and calcium values and the number of days they did not comply with fluid restriction. Conclusion: It was determined that there was no significant relationship between non-compliance with diet and fluid restriction and the severity of fatigue. It was found that the severity of fatigue was lower in patients who complied with diet and fluid restriction, although not significantly lower than in those who did not comply.

RESUMO Objetivo: Este estudo foi conduzido para determinar a relação entre a não aderência à restrição alimentar e hídrica, o índice de massa corporal e a severidade da fadiga em pacientes recebendo diálise. Método: Foi realizado um estudo descritivo e transversal com 42 pacientes recebendo diálise. Os dados foram coletados empregando o "Formulário de informações gerais", Índice de Massa Corporal, "Escala de Severidade da Fadiga" e "Dieta da Diálise e Escala de Incompatibilidade Hídrica". Os dados foram avaliados usando porcentagens, médias, ANOVA unidirecional, testes T e testes de correlação de Pearson. Resultados: O número médio de dias que os pacientes não cumpriram os requisitos da dieta foi de 3,69 ± 4,85 e o número médio de dias que não cumpriram os requisitos da restrição hídrica foi de 2,71 ± 5,02. Foi constatado que a idade e o estado civil dos pacientes afetavam a severidade da fadiga. Foi constatado que os casos estavam associados aos valores de creatinina e cálcio e ao número de dias que não cumpriam os requisitos da restrição hídrica. Conclusão: Foi determinado que não houve relação significativa entre o não cumprimento dos requisitos da dieta e da restrição hídrica e a severidade da fadiga. Foi constatado que a severidade da fadiga foi menor nos pacientes que cumpriram os requisitos da dieta e restrição hídrica, embora não significativamente menor em comparação àqueles que não cumpriram.

Predictors of excess fluid volume in hemodialysis patients: an observational study / Preditores de volume excessivo de líquidos em pacientes em hemodiálise: estudo observacional / Predictores de volumen excesivo de líquidos en pacientes en hemodiálisis: estudio observacional

ABSTRACT Objectives: to assess risk factors for excess fluid volume in hemodialysis patients. Methods: a retrospective case-control study was conducted. A total of 392 patients (196 cases and 196 controls) from two hemodialysis centers were included. Sociodemographic data and 23 risk factors for excess fluid volume were assessed using a data collection form. Data were analyzed using a multivariate logistic regression model. Results: the insufficient knowledge (OR=2.06), excessive fluid intake (OR=2.33), inadequate fluid removal during hemodialysis (OR=2.62) and excessive sodium intake (OR=1.91) risk factors may increase the chance of occurrence of excess fluid volume in hemodialysis patients by approximately two times. Education level (OR=0.95) and age (OR=0.97) are protective factors for excessive fluid volume. Conclusions: knowing these risk factors may help nurses with accurate and rapid diagnostic inference of the risk of excessive fluid volume.

RESUMO Objetivos: avaliar os fatores de risco para o excesso de volume de líquidos em pacientes em hemodiálise. Métodos: estudo retrospectivo caso-controle. Foram incluídos 392 pacientes (196 casos e 196 controles) de dois centros de hemodiálise. Dados sociodemográficos e 23 fatores de risco para excesso de volume de líquidos foram avaliados por meio de formulário de coleta de dados. Os dados foram analisados por meio de modelo de regressão logística multivariada. Resultados: os fatores de risco conhecimento insuficiente (OR=2,06), ingestão excessiva de líquidos (OR=2,33), retirada inadequada de líquidos durante hemodiálise (OR=2,62) e ingestão excessiva de sódio (OR=1,91) podem aumentar a chance de ocorrência de excesso de líquidos volume em pacientes em hemodiálise em aproximadamente duas vezes. Escolaridade (OR=0,95) e idade (OR=0,97) são fatores de proteção para volume excessivo de líquidos. Conclusões: conhecer esses fatores de risco pode auxiliar enfermeiros na inferência diagnóstica precisa e rápida do risco de volume excessivo de líquidos.

Objective: to evaluate the effect of an educational video on the knowledge, attitude, and practice of self-care with arteriovenous fistula in patients undergoing hemodialysis treatment. Method: randomized controlled clinical trial, with two arms and single-blind. The intervention used an educational video on arteriovenous fistula self-care. The Fistula Self-Care Knowledge, Attitude, and Practice Scale was applied to 27 renal patients on hemodialysis in the control group and 28 in the intervention group at baseline, after seven and fourteen days. The data was analyzed using the Statistical Package for the Social Sciences software, using the chi-square test, Student's t-test, Mann-Whitney test, and Friedman's test with post-hoc analysis for multiple comparisons. Results: there were statistically significant differences in the knowledge and practice of self-care with the fistula at 0, 7 and, 14 days in the intervention (p= 0.004 and p<0.001, respectively) and control groups (p<0.001 for knowledge and practice). Attitude showed a significant difference at follow-up (p<0.001), but the post-hoc analysis did not confirm the significance obtained. Conclusion: patients' knowledge and practice showed significant increases at follow-up in the control and intervention groups, while the increase in attitude was not significant in either group. Clinical trial, registration number: U1111-1241-6730.
