ABSTRACT

INTRODUCTION@#An echocardiographic calcium score (ECS) predicts cardiovascular disease (CVD) in the general population. Its utility in peritoneal dialysis (PD) patients is unknown.@*METHODS@#This cross-sectional study assessed 125 patients on PD. The ECS (range 0-8) was compared between subjects with CVD and those without.@*RESULTS@#Among the subjects, 54 had CVD and 71 did not. Subjects with CVD were older (69 years vs. 56 years, P < 0.001) and had a higher prevalence of diabetes mellitus (DM) (81.5% vs. 45.1%, P < 0.001). They had lower diastolic blood pressure (72 mmHg vs. 81 mmHg, P < 0.001), lower phosphate (1.6 mmol/L vs. 1.9 mmol/L, P = 0.002), albumin (30 g/L vs. 32 g/L, P = 0.001), parathyroid hormone (34.4 pmol/L vs. 55.8 pmol/L, P = 0.002), total cholesterol (4.5 vs. 4.9, P = 0.047), LDL cholesterol (2.4 mmol/L vs. 2.8 mmol/L, P = 0.019) and HDL cholesterol (0.8 mmol/L vs. 1.1 mmol/L, P = 0.002). The ECS was found to be higher in subjects with CVD than in those without (2 vs. 1, P = 0.001). On multivariate analysis, only DM and age were independently associated with CVD.@*CONCLUSION@#The ECS was significantly higher in PD patients with CVD than in those without, reflecting a higher vascular calcification burden in the former. It is a potentially useful tool to quantify vascular calcification in PD patients.

ABSTRACT

@#Heart failure (HF) is a major cause of significant morbidity, mortality, and hospitalization worldwide including the Philippines. Congenitally corrected transposition of the great arteries (C-TGA) occurs when the right atrium enters the morphological left ventricle which gives rise to the pulmonary artery and the left atrium communicates with the right ventricle which gives rise to the aorta. Heart failure can occur in C-TGA especially if associated with other heart defects. Ideal management is anatomic correction via surgery to prevent or address heart failure. Peritoneal dialysis has been used as a therapeutic intervention for patients with refractory heart failure and kidney injury with or without kidney failure due to its gentler fluid removal compared to conventional ultrafiltration resulting in less myocardial stunning and neurohormonal activation. We present the case of a patient with heart failure who started on peritoneal dialysis (PD) as an adjunct therapy for fluid management after failing to satisfactorily achieve volume control with diuretics. The patient is a 56-year-old man with C-TGA admitted for decompensated heart failure. He was initially treated with intravenous diuretics on the first admission but was readmitted after 3 months for decompensation this time with borderline low blood pressure making diuresis difficult. The patient was given loop diuretics, tolvaptan, and angiotensin receptor neprilysin inhibitor (ARNI) but still with decreasing trends in urine output and inadequate symptom control. PD was initiated before discharge with subsequent improvement in heart failure symptoms. The patient was on regular follow-up for PD maintenance and titration of heart failure medication. In this case report, we have shown how PD can be an effective adjunct to guideline-directed medical therapy in patients with severely symptomatic heart failure who have an unstable hemodynamic status and for which volume management cannot be satisfactorily achieved with diuretics.

ABSTRACT

Peritoneal ultrafiltration failure is a common reason for peritoneal dialysis (PD) withdrawal as well as mortality in PD patients. Based on the three-pore system, inter-cellular small pores and trans-cellular ultra-small pores (aquaporin-1) are mainly responsible for water transfer across the peritoneum. Both small and ultra-small pores-dependent water (free water) transport decline accompanied with time on PD, with more significant decrease in free water, resulting in peritoneal ultrafiltration failure. The reduction of free water transport is associated with fast peritoneal solute transfer, reduced crystalloid osmotic gradient due to increased interstitial glucose absorption, and declined osmotic conductance to glucose resulted from impaired aquaporin-1 function and peritoneal interstitial fibrosis. The decline of small pore-based water is mainly because of fast loss of crystalloid osmotic gradient, decrease of hydrostatic pressure mediated by peritoneal vasculopathy, as well as reduced absolute number of small pores. The current review discusses the advance on pathogenesis of acquired peritoneal ultrafiltration failure in long-term PD.

ABSTRACT

Objective: To explore the etiological diagnostic value of metagenomic next-generation sequencing (mNGS) in peritoneal dialysis (PD)-related peritonitis. Methods: The study was a retrospective cohort study. The clinical data of patients with PD-related peritonitis who were treated and underwent microbial cultivation and mNGS test at the same time from June 2020 to July 2021 in the Affiliated Drum Tower Hospital, Medical School of Nanjing University were analyzed. The positive rate, detection time and consistency between mNGS test and traditional microbial culture were compared. Results: A total of 18 patients with age of (50.4±15.4) years old and median dialysis time of 34.0 (12.4, 62.0) months were enrolled in the study, including 11 males and 7 females. Pathogenic microorganisms were isolated in 17 patients by mNGS test, with a positive rate of 17/18, which was higher than 13/18 of microbial culture, but the difference was not statistically significant (P=0.219). Both mNGS test and microbial culture isolated positive pathogenic bacteria in 12 patients, and mNGS test isolated the same types of pathogenic bacteria as microbial cultivation did in 11 patients. In five patients with negative microbial culture, mNGS test also isolated pathogenic microorganisms, including 3 cases of Staphylococcus epidermidis, 1 case of Mycobacterium tuberculosis and 1 case of Ureaplasma urealyticum. In 1 patient, microbial culture isolated pathogenic bacteria (Escherichia coli) whereas mNGS test did not. The detection time of mNGS was 25.0 (24.0, 27.0) h, which was significantly shorter than 89.0 (72.8, 122.0) h of microbial culture (Z=3.726, P<0.001). Conclusions: mNGS test can improve the detection rate of pathogenic microorganisms in PD-related peritonitis and greatly shorten the detection time, and has good consistency with microbial culture. mNGS may provide a new approach for pathogen identification of PD-related peritonitis, especially refractory peritonitis.

ABSTRACT

Objective To investigate the treatment outcomes,prognosis,and risk factors of treatment failure of peritoneal dialysis associated peritonitis (PDAP) caused by Klebsiella pneumoniae,and thus provide clinical evidence for the prevention and treatment of this disease. Methods The clinical data of PDAP patients at four peritoneal dialysis centers from January 1,2014 to December 31,2019 were collected retrospectively.The treatment outcomes and prognosis were compared between the patients with PDAP caused by Klebsiella.pneumoniae and that caused by Escherichia coli.Kaplan-Meier method was employed to establish the survival curve of technical failure,and multivariate Logistic regression to analyze the risk factors of the treatment failure of PADP caused by Klebsiella pneumoniae. Results In the 4 peritoneal dialysis centers,1034 cases of PDAP occurred in 586 patients from 2014 to 2019,including 21 cases caused by Klebsiella pneumoniae and 98 cases caused by Escherichia coli.The incidence of Klebsiella pneumoniae caused PDAP was 0.0048 times per patient per year on average,ranging from 0.0024 to 0.0124 times per patient per year during 2014-2019.According to the Kaplan-Meier survival curve,the technical failure rate of Klebsiella pneumoniae caused PDAP was higher than that of Escherichia coli caused PDAP (P=0.022).The multivariate Logistic regression model showed that long-term dialysis was an independent risk factor for the treatment failure of Klebsiella pneumoniae caused PDAP (OR=1.082,95%CI=1.011-1.158,P=0.023).Klebsiella pneumoniae was highly sensitive to amikacin,meropenem,imipenem,piperacillin,and cefotetan,and it was highly resistant to ampicillin (81.82%),cefazolin (53.33%),tetracycline (50.00%),cefotaxime (43.75%),and chloramphenicol (42.86%). Conclusion The PDAP caused by Klebsiella pneumoniae had worse prognosis than that caused by Escherichia coli,and long-term dialysis was an independent risk factor for the treatment failure of Klebsiella pneumoniae caused PDAP.

ABSTRACT

RESUMEN Objetivo. Comparar la supervivencia de pacientes con enfermedad renal crónica (ERC) en hemodiálisis (HD) versus diálisis peritoneal (DP). Materiales y métodos. Se realizó un análisis de supervivencia de una cohorte retrospectiva de pacientes ≥ 18 años que iniciaron HD versus DP en el Hospital Víctor Lazarte Echegaray del 2015 al 2019. Se analizaron las covariables: edad, sexo, diabetes mellitus con causa de ERC, catéter venoso central temporal (CVC) como acceso vascular inicial y tasa de filtración glomerular. Se calculó la supervivencia con curvas de Kaplan-Meier para la cohorte global y para edad ≥ 60 años, diabetes mellitus como causa de ERC y CVC. Se estimó el riesgo de fallecer mediante Hazard Ratio (HR) según el modelo de riesgos proporcionales de Cox para cada covariable ajustada a la modalidad de diálisis en un análisis bivariado y multivariado considerando diferencia significativa si el valor de p < 0,05. Resultados. Se incluyeron 368 pacientes en HD de los cuales fallecieron 129 (35,1%) y 172 pacientes en DP de los cuales fallecieron 66 (38,4%) (p=0,455). La probabilidad acumulada de supervivencia a los 60 meses para HD fue de 30% y para DP fue de 37% con curvas de supervivencia similares (p=0,719). La mediana del tiempo de sobrevida en HD fue de 32 meses (RIC: 20-53) y en DP fue de 32,5 meses (RIC: 18-57) (p=0,999). Se determinó que las covariables asociadas con una mayor mortalidad ajustadas a la modalidad de diálisis fueron edad ≥60 años (HR 1,77; p<0,001) y diabetes mellitus como causa de ERC (HR 1,63; p=0,002). Conclusiones. La supervivencia de los pacientes con enfermedad renal crónica en HD y DP fue similar.


ABSTRACT Objective. To compare the survival of patients with chronic kidney disease (CKD) on hemodialysis (HD) versus peritoneal dialysis (PD). Materials and methods. Survival analysis of a retrospective cohort of patients ≥ 18 years who started HD versus PD at the Victor Lazarte Echegaray Hospital from 2015 to 2019. We analyzed the following covariates: age, sex, diabetes mellitus as cause of CKD, temporary central venous catheter (CVC) as initial vascular access and glomerular filtration rate. Survival was calculated with Kaplan-Meier curves for the overall cohort and for age ≥ 60 years, diabetes mellitus as a cause of CKD and CVC. The risk of death was estimated by Hazard Ratio (HR) according to the Cox proportional hazards model for each covariate adjusted for dialysis type in a bivariate and multivariate analysis considering significant difference if the p-value < 0.05. Results. We included 368 patients on HD of whom 129 (35.1%) died, and 172 patients on PD of whom 66 (38.4%) died (p=0.455). The cumulative probability of survival at 60 months for HD was 30% and for PD was 37% with similar survival curves (p=0.719). The median survival time for HD was 32 months (IQR: 20-53) and for PD was 32.5 months (IQR: 18-57) (p=0.999). The covariates associated with higher mortality adjusted for dialysis type were age ≥60 years (HR 1.77; p<0.001) and diabetes mellitus as a cause of CKD (HR 1.63; p=0.002). Conclusions. Survival of patients with CKD on HD and PD was similar.

ABSTRACT

Estimado director: La COVID-19 afecta a los pacientes con enfermedad renal crónica (ERC) en diálisis,1,2 ya que estos presentan factores de riesgo para desarrollar enfermedad grave, como diabetes mellitus, hipertensión arterial y edad mayor de 65 años. A esto se une la uremia, la inflamación crónica, el trastorno mineral óseo y la diálisis condicionan inmunosupresión crónica.3 La uremia produce cambios en la inmunidad innata y adaptativa y condiciona la disminución de la habilidad bactericida de los neutrófilos, la hiporeactividad de monocitos y diferenciación disminuida de células dendríticas, respuesta de células T alteradas, activación de la apoptosis inducida de células T y B, disminución de linfocitos B, cambios en la relación Th1/Th2 y disminución en número y actividad de células "natural killers".4,5 Además, en la ERC existe una alteración del sistema renina-angiotensina-aldosterona y de la relación ECA/ECA-2, que condiciona mayor susceptibilidad y peores resultados ante la infección por COVID-19.6 A pesar de ello, en diálisis, se ha reportado una cifra elevada de pacientes asintomáticos7 y también, síntomas gastrointestinales como náuseas, vómitos y diarrea,8,9 que son factores que provocan la diseminación de la enfermedad. Resalta la presencia de linfopenia y el patrón de vidrio esmerilado en gran número de pacientes, aunque también es frecuente la neumonía bilateral.6 Igualmente, los índices neutrófilo/linfocito y plaquetas/linfocitos se identifican como marcadores pronósticos tempranos de severidad de COVID-19 incluso en pacientes en hemodiálisis.10,11,12 Los pacientes con ERC deben continuar la terapia dialítica antes, durante o tras la infección por COVID-19. En ese sentido, se ha planteado que la diálisis peritoneal podría minimizar el riesgo de contraer la enfermedad por ser una terapia domiciliaria. Su uso en pacientes con falla renal y COVID-19 es segura, ya que brinda estabilidad hemodinámica, no precisa de anticoagulación ni de acceso vascular, puede iniciarse en forma aguda sin mayores complicaciones, disminuye la exposición del personal, puede ser monitorizada por teleconsulta y sus resultados son similares en comparación a las técnicas extracorpóreas.13,14,15 Presentamos nuestra experiencia en el manejo de cuatro pacientes con ERC, con infección por COVID-19 e iniciaron diálisis peritoneal, al no contar con hemodiálisis hospitalaria en su Centro Asistencial en Juliaca, Perú; ubicada a 3 827 metros sobre el nivel del mar. Dos de ellos eran hombres y tres tenían antecedente de hipertensión arterial. Los cuatro fueron hospitalizados en área COVID-19 y realizaron diálisis peritoneal manual, recibieron entrenamiento a cargo de la enfermera del programa por vía telefónica, por WhatsApp y mediante videos grabados previamente. Hubo complicaciones médicas y quirúrgicas relacionadas a la inserción del catéter en dos pacientes y se utilizó en forma aguda y urgente con un tiempo máximo de 36 h tras la cirugía. Las principales características de los pacientes se presentan en la tabla 1 y sus exámenes de laboratorio en la tabla 2. Al alta, dos de ellos...(AU)

ABSTRACT

Estudos têm avançado no oferecimento de dispositivos digitais para contribuir com o processo ensino aprendizagem no cuidado em saúde. Contudo, a clientela infantil ainda carece de dispositivos específicos, em especial para condições crônicas e que demandam cuidados específicos. Este estudo tem o objetivo de desenvolver um protótipo de serious game voltado para o cuidado da criança com Doença Renal Crônica que realiza tratamento com Diálise Peritoneal. Os objetivos específicos são: identificar as principais dificuldades dos pais e/ou cuidadores na continuidade do tratamento da criança com doença renal crônica em domicílio; identificar as dúvidas mais frequentes de crianças com doença renal crônica e suas famílias em relação à doença e ao seu manejo no domicílio e desenvolver um protótipo de um serious game sobre cuidados relacionados a diálise peritoneal para crianças com DRC. Trata-se de pesquisa metodológica, com referencial teórico da aprendizagem significativa de David P. Ausubel e referencial metodológico de Jeannie Novak. O estudo cumpriu as etapas de conceito e o Game Design Document. Na primeira etapa e para responder aos dois primeiros objetivos específicos, conduziu-se estudo qualitativo com entrevistas semiestruturadas com crianças com Doença Renal Crônica em tratamento com Diálise Peritoneal e com seus principais cuidadores. O referencial para análise foi a análise temática indutiva, o que resultou em três temas: 1) A Diálise Peritoneal: percursos/direções para qualidade de vida e de cuidado da criança com doença renal crônica, com cinco subtemas; 2) O aprendizado para o cuidado na Diálise Peritoneal da criança com doença renal crônica, que envolve dois subtemas; 3) Diálise Peritoneal na criança: tecnologia de informação e comunicação para o cuidado, composto por dois subtemas. Os temas, acrescidos de literatura específica para o cuidado da criança em Diálise Peritoneal, e documentos e normativas do Ministério da Saúde brasileiro, e de manuais para uso do dispositivo na Diálise Peritoneal, fundamentaram o conteúdo do protótipo do serious game. O Game Design Document foi elaborado pela pesquisadora e um designer gráfico. Nele, detalha-se o roteiro, a conceituação artística e a jogabilidade. O serious game conta com cinco lições. O início tem a Escolha e montagem de um avatar; Lição 1: Cuidados com o cateter de Diálise Peritoneal; Lição 2: Alimentação da criança com Doença Renal Crônica; Lição 3: Higiene das mãos; Lição 4: Diálise Peritoneal no domicílio; Lição 5: Prevenção de infecção. O protótipo contém imagens para colorir, figuras que demonstram alimentação saudável, interação com jogador para higiene das mãos, sequência a ser indicada para a realização da diálise peritoneal e um quiz sobre peritonite. O jogador avança no game ao acertar cada proposta de cada lição. Como fragilidades, indicam-se o número de participantes nas entrevistas e a não construção do protótipo junto com as crianças. Das potencialidades do protótipo do serious game, tem-se a oferta de dispositivo que fortalece o processo de ensino aprendizagem da criança com doença renal crônica em tratamento dialítico. O seu uso pode ultrapassar a criança e alcançar não somente os cuidadores, como também profissionais de saúde, no cenário hospitalar ou da atenção básica, que poderão utilizá-lo como ferramenta de capacitação para o cuidado no domicílio. O estudo permitiu entender todo o processo de idealização, produção e desenvolvimento de jogos e tecnologias voltadas à educação, demonstrando que é possível tornar a aprendizagem prazerosa e associar conteúdos teóricos e científicos à cenários lúdicos. Estudo futuro validará o protótipo com especialistas sobre o tema e, posteriormente, com a população-alvo, com intuito de consolidar a construção do serious game propriamente dito


Studies have advanced in order to offer digital devices to contribute to the teaching-learning process in health care. However, the child clientele still lacks specific devices, especially for chronic conditions which require specific care. This study aims to develop a prototype of a serious game aimed at the care of children with Chronic Kidney Disease undergoing treatment with Peritoneal Dialysis. The specific objectives are: to identify the main difficulties of parents and/or caregivers in continuing the treatment of children with chronic kidney disease at home; to identify the most frequent doubts of children with chronic kidney disease and their families regarding the disease and its management at home and to develop a prototype of a serious game about care related to peritoneal dialysis for children with Chronic Kidney Disease. This is a methodological research, with a theoretical framework of meaningful learning by David P. Ausubel and a methodological framework by Jeannie Novak. The study fulfilled the concept steps and the Game Design Document. In the first stage and to respond to the first two specific objectives, a qualitative study was conducted with semi-structured interviews with children with Chronic Kidney Disease undergoing Peritoneal Dialysis and with their main caregivers. The reference for analysis was inductive thematic analysis, which resulted in three themes: 1) Peritoneal Dialysis: pathways/directions for quality of life and care for children with chronic kidney disease, with five subthemes; 2) Learning for the care in Peritoneal Dialysis of the child with chronic kidney disease, which involves two sub-themes; 3) Peritoneal Dialysis in children: information and communication technology for care, consisting of two sub-themes. manuals for using the device in Peritoneal Dialysis, supported the content of the serious game prototype. The Game Design Document was prepared by the researcher and a graphic designer. In it, the script, the artistic concept and the gameplay are detailed. The serious game has five lessons. The beginning has the choice and assembly of an avatar; Lesson 1: Peritoneal Dialysis catheter care; Lesson 2: Feeding the child with Chronic Kidney Disease; Lesson 3: Hand hygiene; Lesson 4: Peritoneal Dialysis at Home; Lesson 5: Prevention of Infection. The prototype contains coloring images, figures that demonstrate healthy eating, interaction with a player for hand hygiene, sequence to be indicated for performing Peritoneal Dialysis and a quiz on peritonitis. The player advances in the game by hitting each proposal of each lesson. As weaknesses, the number of participants in the interviews and the failure to build the prototype together with the children with Chronic Kidney Disease are indicated. Serious game prototype, has potential as device that strengthens the teaching-learning process of children with Chronic Kidney Disease undergoing dialysis treatment. Its use can go beyond the child and reach not only caregivers, but also health professionals, in the hospital or primary care setting, who can use it as a training tool for home care. The study allowed us to understand the entire process of idealization, production and development of games and technologies aimed at education, demonstrating that it is possible to make learning enjoyable and associate theoretical and scientific content with playful scenarios. A future study will validate the prototype with experts on the subject and, later, with the target population, in order to consolidate the construction of the serious game itself

ABSTRACT

Objective To explore the clinical characteristics and treatment of Pseudomonas peritoneal dialysis-associated peritonitis(PsP). Methods The data of patients receiving peritoneal dialysis in four tertiary hospitals in Jilin province from 2015 to 2019 were retrospectively analyzed.According to the etiological classification,the patients with peritoneal dialysis-associated peritonitis(PDAP)were classified into PsP group and non-PsP group.The incidence of PsP was calculated,and the clinical characteristics and treatment outcomes of the two groups were compared.Kaplan-Meier method was used to draw the survival curve,and Cox regression was performed to analyze the risk factors affecting the technical failure of PsP.The treatment options of Pseudomonas aeruginosa-caused PDAP and the drug sensitivity of PsP were summarized. Results A total of 1530 peritoneal dialysis patients with complete data were included in this study,among which 439 patients had 664 times of PDAP.The incidence of PsP was 0.007 episodes/patient-year.PsP group had higher proportion of refractory peritonitis(41.38% vs.19.69%,P=0.005),lower cure rate(55.17% vs.80.79%, P=0.001),and higher extubation rate(24.14% vs.7.09%,P=0.003)than non-PsP group.The technical survival rate of PsP group was lower than that of non-PsP group(P<0.001).Multivariate Cox regression analysis showed that Pseudomonas aeruginosa was an independent risk factor for technical failure in patients with PsP(HR=9.020,95%CI=1.141-71.279,P=0.037).Pseudomonas was highly sensitive to amikacin,meropenem,and piperacillin-tazobactam while highly resistant to compound sulfamethoxazole,cefazolin,and ampicillin. Conclusion The treatment outcome of PsP is worse than that of non-PsP,and Pseudomonas aeruginosa is an independent risk factor for technical failure of PsP.

ABSTRACT

OBJECTIVE@#To develop and validate a risk prediction model of treatment failure in patients with peritoneal dialysis-associated peritonitis (PDAP).@*METHODS@#We retrospectively analyzed the data of patients undergoing peritoneal dialysis (PD) in 3 dialysis centers in Jilin Province who developed PDAP between January 1, 2013 and December 31, 2019. The data collected from the Second Hospital of Jilin University and Second Division of First Hospital of Jilin University) were used as the training dataset and those from Jilin Central Hospital as the validation dataset. We developed a nomogram for predicting treatment failure using a logistic regression model with backward elimination. The performance of the nomogram was assessed by analyzing the C-statistic and the calibration plots. We also plotted decision curves to evaluate the clinical efficacy of the nomogram.@*RESULTS@#A total of 977 episodes of PDAP were included in the analysis (625 episodes in the training dataset and 352 episodes in the validation dataset). During follow-up, 78 treatment failures occurred in the training dataset and 35 in the validation dataset. A multivariable logistic regression prediction model was established, and the predictors in the final nomogram model included serum albumin, peritoneal dialysate white cell count on day 5, PD duration, and type of causative organisms. The nomogram showed a good performance in predicting treatment failure, with a C-statistic of 0.827 (95% CI: 0.784-0.871) in the training dataset and of 0.825 (95% CI: 0.743-0.908) in the validation dataset. The nomogram also performed well in calibration in both the training and validation datasets.@*CONCLUSION@#The established nomogram has a good accuracy in estimating the risk of treatment failure in PDAP patients.

ABSTRACT

INTRODUCTION@#In patients with end-stage kidney disease (ESKD) suitable for peritoneal dialysis (PD), PD should ideally be planned and initiated electively (planned-start PD). If patients present late, some centres initiate PD immediately with an urgent-start PD strategy. However, as urgent-start PD is resource intensive, we evaluated another strategy where patients first undergo emergent haemodialysis (HD), followed by early PD catheter insertion, and switch to PD 48-72 hours after PD catheter insertion (early-start PD). Conventionally, late-presenting patients are often started on HD, followed by deferred PD catheter insertion before switching to PD≥14 days after catheter insertion (deferred start PD).@*METHODS@#This is a retrospective study of new ESKD patients, comparing the planned-start, early-start and deferred-start PD strategies. Outcomes within 1 year of dialysis initiation were studied.@*RESULTS@#Of 148 patients, 57 (38.5%) patients had planned-start, 23 (15.5%) early-start and 68 (45.9%) deferred-start PD. Baseline biochemical parameters were similar except for a lower serum urea with planned-start PD. No significant differences were seen in the primary outcomes of technique and patient survival across all 3 subgroups. Compared to planned-start PD, early-start PD had a shorter time to catheter migration (hazard ratio [HR] 14.13, 95% confidence interval [CI] 1.65-121.04, P=0.016) while deferred-start PD has a shorter time to first peritonitis (HR 2.49, 95% CI 1.03-6.01, P=0.043) and first hospital admission (HR 2.03, 95% CI 1.35-3.07, P=0.001).@*CONCLUSION@#Planned-start PD is the best PD initiation strategy. However, if this is not possible, early-start PD is a viable alternative. Catheter migration may be more frequent with early-start PD but does not appear to impact technique survival.

ABSTRACT

INTRODUCTION@#Cardiovascular morbidity and mortality in end-stage renal failure (ESRF) patients are high. We examined the incidence and predictors of death and acute myocardial infarction (AMI) in ESRF patients on different modalities of dialysis.@*METHOD@#Data were obtained from a population-based database (National Registry Disease Offices) in Singapore. The study cohort comprised all adult patients initiated on dialysis between 2007 and 2012 who were closely followed for the development of death and AMI until September 2014. Cox regression methods were used to identify predictors of death and AMI.@*RESULTS@#Of 5,309 patients, 4,449 were on haemodialysis and 860 on peritoneal dialysis (PD). Mean age of the cohort was 61 (±13) years (44% women), of Chinese (67%), Malay (25%) and Indian (7%) ethnicities. By September 2014, the incidence of all-cause death was 34%; close to a third of the patients died from a cardiovascular cause. Age >60 years and the presence of ischaemic heart disease, diabetes, stroke, peripheral vascular disease and PD were identified as independent predictors of all-cause death. PD patients had lower odds of survival compared to patients on haemodialysis (hazard ratio 1.51, 95% confidence interval 1.35-1.70, P<0.0001). Predictors of AMI in this cohort were older age (>60 years) and the presence of ischaemic heart disease, diabetes, stroke, peripheral vascular disease and current/ex-smokers. There were no significant differences in the incidence of AMI between patients on PD and haemodialysis.@*CONCLUSION@#The short-term incidence of death and AMI remains high in Singapore. Future studies should investigate the benefits of a tighter control of cardiovascular risk factors among ESRF patients on dialysis.

ABSTRACT

Abstract Introduction: Progressive structural changes in the peritoneal membrane occur over the course of treatment in peritoneal dialysis (PD), resulting in an increase in cytokines such as CCL2 and structural changes in peritoneal membrane triggering an increase in CA-125 in dialysate, which reflects a probable local inflammatory process, with possible loss of mesothelial cells. Thus, the current study aimed to evaluate the association between plasma and CCL2 and CA-125 dialysate levels in patients undergoing PD. Methods: Cross-sectional study was conducted with 41 patients undergoing PD. The assessments of CA-125 and CCL2 levels were performed using a capture ELISA. Correlations were estimated using Spearman's correlation and the investigation of the association between the explanatory variables (CCL2) and response variable (CA-125) was done for crude ratio of arithmetic means and adjusted utilizing generalized linear models. Results: A moderate positive correlation was observed between the levels of CA-125 and CCL2 in the dialysate (rho = 0.696). A statistically significant association was found between the levels in the CCL2 and CA-125 dialysate (RoM=1.31; CI = 1.20-1.43), which remained after adjustment for age (RoM = 1.31; CI=1.19-1.44) and for time in months of PD (RoM=1.34, CI=1.22-1.48). Conclusion: The association of CA-125 levels with CCL2 in the dialysate may indicate that the local inflammatory process leads to temporary or definitive changes in peritoneal membrane. A better understanding of this pathogenesis could contribute to the discovery of new inflammatory biomarkers.


Resumo Introdução: Alterações estruturais progressivas na membrana peritoneal ocorrem no decorrer do tratamento em diálise peritoneal (DP), resultando em um aumento de citocinas como CCL2 e alterações estruturais na membrana peritoneal desencadeando um aumento de CA-125 no dialisato, o que reflete um provável processo inflamatório local, com possível perda de células mesoteliais. Assim, o presente estudo teve como objetivo avaliar a associação entre CCL2 e CA-125 no plasma e no dialisato de pacientes submetidos à DP. Métodos: Foi realizado um estudo transversal com 41 pacientes submetidos à DP. As avaliações dos níveis de CA-125 e CCL2 foram realizadas utilizando ELISA de captura. As correlações foram estimadas usando a correlação de Spearman, e a investigação da associação entre as variáveis explicativas (CCL2) e a variável resposta (CA-125) foi feita pela razão bruta das médias aritméticas e ajustada utilizando modelos lineares generalizados. Resultados: Foi observada uma correlação positiva moderada entre os níveis de CA-125 e CCL2 no dialisato (rho = 0,696). Foi encontrada uma associação estatisticamente significativa entre os níveis no dialisato de CCL2 e CA-125 (RoM=1,31; IC = 1,20-1,43), que permaneceu após ajuste por idade (RoM = 1,31; IC=1,19-1,44) e pelo tempo de DP em meses (RoM=1,34, IC=1,22-1,48). Conclusão: A associação dos níveis de CA-125 com CCL2 no dialisato pode indicar que o processo inflamatório local leva a alterações temporárias ou definitivas na membrana peritoneal. Uma melhor compreensão desta patogênese pode contribuir para a descoberta de novos biomarcadores inflamatórios.

ABSTRACT

Abstract Background: Peritoneal dialysis (PD) is gaining track as an efficient/affordable therapy in poor settings. Yet, there is little data regarding differences in quality of life (QoL) of primary caregivers (PCG) of patients in PD and hemodialysis (HD). Aim: To compare the QoL of PCG of patients in PD and HD from an upper middle-income population in a Mexican city. Methods: Cross-sectional study was carried out with PCG of patients in PD (n=42) and HD (n=95) from 4 hospitals (response rate=70.2%). The SF 36-item QoL questionnaire, the Zarit burden interview, and the Goldberg anxiety/depression scale were used. Mean normalized scores for each QoL domain were compared by dialysis type. Adjusted odds were computed using logistic regression to determine the probability of low QoL (<70% of maximum possible score resulting from the added scores of the 8 dimensions). Results: The PD group had higher mean scores for emotional role functioning (+10.6; p=0.04), physical functioning (+9.2; p=0.002), bodily pain (+9.2; p=0.07), social functioning (+5.7; p=0.25), and mental health (+1.3; p=0.71); the HD group had higher scores for physical role functioning (+7.9, p=0.14), general health perception (+6.1; p=0.05), and vitality (+3.3; p=0.36). A non-significant OR was seen in multivariate regression (1.51; 95% CI 0.43-5.31). Zarit scores were similar, but workload levels were lower in the PD group (medium/high: PD 7.2%, HD 14.8%). Anxiety (HD 50.5%, PD 19%; p<0.01) and depression (HD 49.5%, PD 16.7%; p<0.01) were also lower in the PD group. Conclusion: Adjusted analysis showed no differences in the probability of low QoL between the groups. These findings add to the value of PD, and strengthen its importance in resource-limited settings.


Resumo Histórico: A diálise peritoneal (DP) vem ganhando terreno como terapia eficiente/acessível em ambientes pobres. Contudo, há poucos dados sobre diferenças na qualidade de vida (QV) dos cuidadores primários (CP) de pacientes em DP e hemodiálise (HD). Objetivo: Comparar QV dos CP de pacientes em DP e HD de uma cidade mexicana de renda média. Métodos: Estudo transversal com CP de pacientes em DP (n=42) e HD (n=95) de 4 hospitais (taxa resposta=70,2%). Aplicou-se o questionário QV-36 itens, entrevista de sobrecarga de Zarit e escala de ansiedade/depressão Goldberg. Escores médios normalizados para cada domínio de QV foram comparados por tipo de diálise. Probabilidades ajustadas foram calculadas usando regressão logística para determinar a probabilidade de baixa QV (<70% da pontuação máxima possível resultante das pontuações adicionadas das 8 dimensões). Resultados: O grupo DP apresentou escores médios mais altos para aspectos emocionais (+10,6; p=0,04), capacidade funcional (+9,2; p=0,002), dor (+9,2; p=0,07), aspectos sociais (+5,7; p=0,25), saúde mental (+1,3; p=0,71); o grupo HD teve pontuação maior para aspectos físicos (+7,9, p=0,14), estado geral de saúde (+6,1; p=0,05), vitalidade (+3,3; p=0,36). Uma probabilidade não significativa foi observada na regressão multivariada (OR=0,66; 95% IC 0,18-2,31). Os escores de Zarit foram semelhantes, mas os níveis da sobrecarga foram menores na DP (médio/alto: DP 7,2%, HD 14,8%). Ansiedade (50,5% vs 19%; p<0,01) e depressão (49,5% vs 16,7%; p<0,01) foram menores na DP. Conclusão: O risco de baixa QV entre grupos não foi diferente na análise ajustada. Estes achados fortalecem a importância da DP em ambientes com recursos limitados.

ABSTRACT

Introducción: los pacientes con enfermedad renal crónica (ERC), y en específico los que tienen tratamiento renal sustitutivo (TRS), se ven afectados en su ciclo circadiano y en su calidad del sueño. Objetivo: evaluar la calidad del sueño de los pacientes con enfermedad renal crónica que acuden al servicio de Nefrología de una unidad médica de segundo nivel de atención. Metodología: estudio comparativo en pacientes con ERC del servicio de Nefrología, clasificados en tres grupos, dos de ellos en terapia de reemplazo renal (diálisis peritoneal y hemodiálisis) y uno sin terapia de reemplazo renal (prediálisis). Para la calidad del sueño se utilizó la escala de Pittsburgh, se incluyeron datos sociodemográficos y parámetros bioquímicos. Los datos se analizaron median- te comparación de frecuencias con Chi cuadrada, medias con t de Student y ANOVA de un factor. Resultados: se formaron tres grupos: hemodiálisis (n = 75), diálisis peritoneal (n = 58) y prediálisis (n = 71). La edad media fue de 53.5 años; la calidad subjetiva del sueño fue buena en el 48% del total y en el 54.9% de los pacientes en prediálisis (p < 0.05). Al aplicar la escala de Pittsburgh, el 80.4% del total y el 84.5% de los pacientes en diálisis reportaron una calidad de sueño mala. De las siete dimensiones evaluadas, dos fueron diferentes en los tres grupos (p < 0.05). Conclusiones: la percepción del paciente sobre la calidad del sueño habitualmente se sobreestima, lo que indica una adaptación a un sueño ineficiente. Debido a las características de estos pacientes es importante mantener un control de sus parámetros bioquímicos, que también tienen un impacto en la calidad del sueño.


Introduction: In patients with chronic kidney disease (CKD) and specifically with renal replacement therapy (RRT), their circadian cycle and consequently their sleep quality are affected. Objective: To evaluate the quality of sleep in patients with chronic kidney disease attends at the nephrology service. Methods: Comparative study in patients with chronic kidney disease from the nephrology service classified into three groups, two of them had renal replacement therapy (peritoneal dialysis and hemodialysis) and one without renal replacement therapy (predialysis). For the quality of sleep we used the Pittsburgh Scale, sociodemographic data and biochemical parameters were included. Comparison of frequencies with chi-square, means with Student's t and Anova of one factor. Results: Three groups were formed: hemodialysis (n = 75), peritoneal dialysis (n = 58) and predialysis (n = 71). The mean age was 53.5 years; the subjective quality of sleep was "good" in 48.0% of the total and in 54.9% of predialysis patients (p <0.05). When applying the Pittsburgh scale, 80.4% of the total and 84.5 of the dialysis patients reported a "poor" quality of sleep. Of the seven dimensions evaluated, two were different in the three groups (p < 0.05) Conclusions: The patient's perception of the quality of sleep is regularly overestimated, which indicates an adaptation to this dream habit. Due to the characteristics of these patients, it is important to keep a check on their biochemical parameters, which also have an impact on the quality of sleep.

ABSTRACT

Abstract The coronavirus (Sars-Cov-2) pandemic raised the need for social distance to reduce its spread. Chronic kidney disease patients on renal replacement therapy are especially susceptible to developing the most severe form of COVID-19, and, at the same time, require regular medical and multidisciplinary periodic follow-up. On an emergency basis, Brazil's professional regulatory bodies authorized telehealth assistance, which made possible to migrate from face-to-face to distance appointments in health services across the country, when necessary. This article's main objective is to describe the process of developing and implementing telehealth for monitoring renal transplant patients and patients on peritoneal dialysis during the COVID-19 pandemic.


Resumo A pandemia do coronavírus (Sars-CoV-2) trouxe a necessidade do isolamento social para a diminuição de sua propagação. Pacientes renais crônicos em terapia renal substitutiva são especialmente suscetíveis a desenvolverem a forma mais grave da covid-19, e, ao mesmo tempo, necessitam de acompanhamento médico e multidisciplinar regular com consultas periódicas. Em caráter emergencial, órgãos regulatórios profissionais brasileiros passaram a autorizar o atendimento da equipe de saúde por meio da teleconsulta, o que tornou possível a migração das consultas presenciais para consultas a distância nos serviços de saúde em todo o país, quando necessário. O principal objetivo deste artigo foi descrever o processo de desenvolvimento e implementação da teleorientação para acompanhamento de pacientes transplantados renais e em diálise peritoneal de um serviço de Joinville, SC, durante a pandemia de covid-19.

ABSTRACT

Introducción: en México 130 000 personas viven con enfermedad renal crónica (ERC). Las afecciones cardiacas son los problemas clínicos más frecuentes; 45% de las muertes de pacientes en terapia sustitutiva tienen un origen cardiaco. Objetivo: identificar la probabilidad de presentar falla cardiaca aguda (FCA) en pacientes con ERC en el Servicio de Urgencias Adultos de un hospital de segundo nivel. Material y métodos: estudio de casos (111) y controles (103). Los casos se definieron como pacientes con ERC ingresados a Urgencias por FCA comparados con controles, pacientes con ERC que ingresaron por otro diagnóstico diferente. Se realizó regresión logística binaria y se determinaron razones de momios (RM) e intervalos de confianza al 95% (IC 95%). Un valor de p ˂ 0.05 fue significativo. Resultados: la hipertensión arterial (RM 7.12, IC 95% 2.3-22.06, p = 0.01), el uso de 3 o más antihipertensivos (RM, 2.903, IC 95% 1.19-7.11, p = 0.02), empleo de inhibidores de la enzima convertidora de angiotensina (IECA) (RM 4.25, IC 95% 1.78-10.09, p = 0.01), antagonistas de los receptores de angiotensina-II (ARA-II) (RM 2.41, IC 95% 1.19-4.89, p = 0.014), diuréticos (RM 42.87, IC 95% 9.02-203.63, p = 0.00), diálisis peritoneal (RM 2.48, IC 95% 1.25-4.81, p = 0.009) y hemodiálisis (RM 0.40, IC 95% 0.20-0.79, p = 0.009) tuvieron significación estadística. Conclusiones: los pacientes con ERC con hipertension arterial, empleo de IECA, ARA-II, diuréticos y en dialisis peritoneal, tuvieron mayor probabilidad de presentar falla cardiaca aguda, mientras que los pacientes que se encontraban en hemodiálisis tuvieron menor probabilidad.


Background: In Mexico 130,000 people live with chronic kidney disease (CKD). Heart conditions are the most frequent clinical problems; 45% of the deaths of patients in replacement therapy have a cardiac origin. Objective: To identify the probability of presenting acute heart failure (AHF) in patients with CKD in the Adult Emer- gency Department (AED) of a second-level hospital. Material and methods: Case-control study with 111 cases and 103 controls. Cases were defined as patients with CKD admitted to AED for AHF compared with controls: patients with CKD who were admitted for a different diagnosis. Binary logistic regression was performed and odds ratio (OR) and 95% confidence intervals (95% CI) were determined. A value of p ˂ 0.05 was considered significant. Results: Arterial hypertension (OR 7.12, 95% CI 2.3-22.06, p = 0.01), the use of 3 or more antihypertensive drugs (OR 2.903, 95% CI 1.19-7.11, p = 0.02), the use of inhibitors of angiotensin converting enzyme (ACE inhibitors) (OR 4.25, 95% CI 1.78-10.09, p = 0.01), angiotensin II receptor blockers (ARBs) (OR 2.41, 95% CI 1.19-4.89, p = 0.014), diuretics (OR 42.87, 95% CI 9.02-203.63, p = 0.00), peritoneal dialysis (OR 2.48, 95% CI 1.25-4.81, p = 0.009) and hemodialysis (OR 0.40, 95% CI 0.20-0.79, p = 0.009) had statistical significance. Conclusions: CKD patients with arterial hypertension, use of ACE inhibitors, ARBs, diuretics and peritoneal dialysis were more likely to present AHF, while patients who were on hemodialysis were less likely to presenting it.
