Experiencia en hemodiálisis domiciliaria en España / Spanish home hemodialysis experience

Resumen Antecedentes: existe actualmente un interés creciente, a nivel mundial, por las posibilidades que ofrece la hemodiálisis domiciliaria, la cual se encuentra más extendida en países del norte de Europa, Canadá, Reino Unido, Estados Unidos, Australia y Nueva Zelanda. En España, ha crecido de manera muy lenta, excepto en determinadas regiones como la provincia de Castellón, donde hemos puesto especial interés en la expansión de las técnicas dialíticas domiciliarias. Objetivo: describir la experiencia en el programa de hemodiálisis domiciliaria del Hospital General de Castellón. Metodología: estudio descriptivo de los pacientes incluidos en el programa de hemodiálisis domiciliaria del Hospital General de Castellón, desde su inicio en enero del 2008 hasta diciembre del 2017. Resultados: en su conjunto, entrenamos a 41 pacientes, de los que 36 llegaron a hemodializarse en casa (régimen corto-diario). La edad de los pacientes era 58,3±13,4 años; y el índice de Charlson, 4,1±1,6. 62 % de los pacientes eran hombres, 25,6 % padecían diabetes mellitus; 15,4 % tenían diagnóstico de insuficiencia cardíaca y 32 % eran portadores de fístula de hemodiálisis. El 38,5 % de los pacientes en edad laboral estaba activo. Obtuvimos una supervivencia técnica considerando el evento muerte+fallo técnico, censurando el trasplante, del 79,4 % al año, 75,2 % a los 2 años y 42,1 % a los 5 años. En el análisis univariante, resultaron determinantes la edad, la presencia de diabetes mellitus y la presencia de insuficiencia cardíaca. En el análisis multivariante, solo se mantuvo la insuficiencia cardíaca. Las reducciones semanales de fósforo y beta-2-microglobulina fueron significativamente mayores con hemodiálisis corta diaria, en comparación con la hemodiafiltración on-line. La hemodiafiltración on-line fue superior en la reducción semanal a partir de los 17 800 daltons para la mioglobina. Conclusiones: la hemodiálisis domiciliaria es una técnica posible que ofrece al paciente una adecuada reinserción sociolaboral, buenos niveles de reducción semanal de toxinas urémicas y una aceptable supervivencia técnica en el tiempo.

Abstract Background: There is currently a growing interest, worldwide, for the possibilities offered by home hemodialysis, which is more widespread in northern European countries, Canada, the United Kingdom, the United States, Australia and New Zealand. In Spain, it has grown very slowly, except in certain regions such as the province of Castellón, where we have placed special interest in the expansion of home dialysis techniques. Objective: To describe the experience in the Home Hemodialysis program of the Hospital General de Castellón. Methodology: Descriptive study of the patients included in the home hemodialysis program of the Hospital General de Castellón, from its beginning in January 2008 to December 2017. Results: As a whole, we trained 41 patients, of whom 36 came to hemodialysis at home (short-day regimen). Age 58,3±13,4 years, Charlson index 4,1±1,6, 62 % men, 25,6 % with diabetes mellitus, 15,4 % with diagnosis of heart failure, 32 % with hemodialysis fistula, 38,5 % of working-age patients were active. We obtained a technical survival considering the event death+technical failure, censoring transplant of 79,4 % a year, 75,2 % at 2 years and 42,1 % at 5 years, resulting determinants of the event in the univariate analysis: age, presence of diabetes mellitus and presence of heart failure, and only heart failure in the multivariate. The weekly reductions of phosphorus and beta-2-microglobulin were significantly greater with daily short hemodialysis with respect to on-line haemodiafiltration. Being the on-line hemodiafiltration superior in the weekly reduction from the 17800 daltons of myoglobin. Conclusions: Home hemodialysis is a possible technique that offers the patient an adequate social-labor reintegration with good levels of weekly reduction of uraemic toxins and an acceptable technical survival over time.

Comparison of technical survival between Tenckhoff double-cuffed straight catheter and swan-neck curled tip catheter in peritoneal dialysis / 中华肾脏病杂志

objective To compare the technical survival between Tenckhoff double-cuffed straight catheter (TC)and swan-neck curled tip catheter (SNC) in peritoneal dialysis (PD). Methods Clinical data of 208 patients received PD in the Peritoneal Dialysis Center of Peking Union Medical College Hospital from January 1999 to December 2007 were analyzed retrospectively. All the patients were divided into two groups according to indwelling catheter. Technical survival and complications associated with the catheter between two groups were compared. Results Demographics and basic information were similar in both groups. The exit-site infection (ESI) rates of TC and SNC were 22.1% and 19.8% (P=0.786), and peritonitis rates of TC and SNC were 31.1% and 22.1% (P=0.159), which were slightly lower in SNC group, but the difference was not significant. Removal of the catheter was found in 27 (13.0%)patients, including 17 cases in TC group (13.9%) and 10 cases in SNC group (11.6%)(P=0.680).The median survival times of catheter in TC group and SNC group were 25 months and 22 months respectively without significant difference (P=0.103). Conclusions There are no significant differences of ESI rate, peritonitis rate and catheter survival between these two catheters in PD. The expensive swan-neck catheter offers no additional advantage. Doctors should choose the catheter according to the economic status of patients.

Comparative Study of Renal Replacement Therapy in Korean Diabetic End-Stage Renal Disease Patients: a Single Center Study

The number of diabetic ESRD patients has increased and death rates of diabetic patients on hemodialysis (HD), peritoneal dialysis (PD) and renal transplantation (RT) have remained higher than the death rate of non-diabetic patients. An attempt was made to compare the clinical characteristics, patients' cumulative survival, and technical survival among the three groups retrospectively according to the mode of renal replacement therapy (RRT), and to analyze the risk factors associated with mortality. A total of 229 diabetic ESRD patients diagnosed between 1986 and 1995 at the Severance Hospital who began dialysis or who underwent a kidney transplant were included and their medical charts were reviewed. Hypertension was the most common co-morbid disease in all study groups. The prevalence of cardiovascular disease was the only co-morbid condition that was significantly different among the three groups, which was highest in the PD group (24.4%) and lowest in the RT group (8%). In the analysis of a patient's cumulative survival rate not adjusted for age and sex, the RT group had the highest survival rate, and the cumulative survival rate of the HD and PD group were similar. The 5-year survival rate of the patients treated with HD, PD and RT was 28.8%, 19.8%, and 72.0%, respectively. No differences were observed in the patient's cumulative survival rate between the HD and PD patients even when it was adjusted for age. When adjusted for age, sex and risk factors, the relative death rate of the RT group was significantly lower in male patients younger than 60 years of age. With the exception of male patients younger than 60 years of age, the PD group showed a slightly lower relative death rate although it was not significant. The multiple Cox regression analysis of patient survival showed that age, serum albumin, BUN, mean hospital days, the presence of cardiovascular disease at the initiation of RRT were associated with mortality. The analysis of the technique survival rate revealed a better result in the HD group compared to PD group, but a limitation in being able to investigate the AVF function disturbed the accuracy of the analysis of technical survival rate. In conclusion, the survival rate between the PD and HD patients was not different and the RT group had the best survival rate. Therefore, kidney transplantation in diabetic ESRD patients should be considered positively if no other contraindicated condition for RT exit.
