Utility of Remote Monitoring in Patients on Automated Peritoneal Dialysis

ABSTRACT Home hemodialysis (HD) and automated peritoneal dialysis (APD) have advantages over HD in hospitals or HD centers. Home therapies are generally less expensive and give patients greater mobility and freedom for work, school, family, and recreational activities. Technological advances have made it possible to complement APD with devices for remote monitoring (RM) of the patient. With them, objective information generated in the APD device is collected and sent to repositories "in the cloud" for analysis or at the time decided by the health team. With APD+RM, it is possible to monitor therapeutic compliance, effective dialysis time, ultrafiltration volumes, inflow and outflow patterns of dialysis fluid, and patient actions to respond to alarms that indicate deviations from the parameters set by the nephrologist. The results of APD+RM show good acceptance by the patient, nephrologists, and nurses, treatment adherence has improved, hospitalizations and technique failure have decreased, and some aspects of quality of life have improved. However, there is a lack of controlled clinical trials that reliably demonstrate lower mortality and comorbidity due to specific causes.

Remote monitoring as a surveillance method in patients on automated peritoneal dialysis for preventing complications and COVID-19 contagion.

BACKGROUND: Due to the health emergency of COVID-19, telemedicine has become more relevant. Remote monitoring conspicuous as a valuable tool for the clinical follow-up of kidney patients, in this case, who are treated with automated peritoneal dialysis. This study aims to describe the use of remote monitoring as a surveillance method in a cohort of patients on automated peritoneal dialysis prevent complications and COVID-19 contagion. METHODS: Study of a cohort of patients who initially participated in a randomized block clinical trial in which the use of Automated Peritoneal Dialysis with Remote Monitoring (APD-RM) was compared with conventional treatment. A descriptive analysis was performed of the rates of infection by COVID-19, the time of incidence until this, mortality, and rates of transfer to hemodialysis. In addition, survival was measured by survival curves. RESULTS: Of the 509 patients, 19 were positive for COVID-19 (incidence rate of 7.0 episodes/100 patient-year), and only six patients recovered from the infection; the death rate was 2.6 % compared to all-cause death of 9.8 %. The most affected group of patients were those over 50 years old, with 71.4 % mortality, in contrast to younger patients infected, with a mortality of 60 %. During the follow-up period, 21 patients were transferred to HD: six due to peritonitis, five due to UF failure, seven due to catheter dysfunction, one due to uremic syndrome, one due to COVID-19, and one by surgical intervention. CONCLUSION: APD-RM patients have a significant advantage over other dialysis therapies because the use of telemedicine not only provides continuity in the patient's clinical treatment but also favors the prevention of COVID-19 infection, the management and prevention of complications inherent to therapy and the preservation of the life of Peritoneal Dialysis patients.

Patient experience in automated peritoneal dialysis with telemedicine monitoring during the COVID-19 pandemic in Mexico: Qualitative study.

AIM: The aim of the study was to understand the experiences of patients on automated peritoneal dialysis (APD) during the period of confinement due to the COVID-19 pandemic. DESIGN: Qualitative exploratory study, phenomenological through semi-structured telephone interview. METHOD: A priori sampling was carried out with patients on APD with remote monitoring and telephone follow-up, in 13 hospitals in Mexico. RESULTS: Twenty-nine informants, mean age 45.41 ± 16.93; 15 women and 14 men. The analysis revealed four categories of analysis: home isolation, clinical follow-up, socioeconomic challenges and infodemic. The experiences of these patients led them to somatize emotions, presenting symptoms such as anxiety, sadness, loneliness, sleep, eating and digestive disorders, situation that sets the tone for future research on telemedicine care models, coping styles, emotional support strategies and socioeconomic impact on patients with chronic home treatments during the pandemic.

Relationship Between the Gut Microbiota and Alzheimer's Disease: A Systematic Review.

BACKGROUND: In recent years, scientific research on the gut microbiota and their relationship with some diseases, including neurological ones, has notably increased. As a result of these investigations, the so-called gut-brain axis arises. Despite its influence on the evolution and development of cognitive impairment, the gut-brain axis is little defined and demonstrated. OBJECTIVE: To provide the best scientific evidence available on the relationship between the gut microbiota and Alzheimer's disease. METHOD: Systematic and narrative review of the information generated in the last 5 years in national and international databases, in English and Spanish. RESULTS: Eight observational studies were selected, carried out in humans and, therefore, suitable for inclusion in this review. CONCLUSION: The results of these studies support the hypothesis that there is a relationship between the gut microbiota and cognitive disorders through the gut-brain axis. However, today, there is a substantial lack of human studies, especially clinical trials, which makes it difficult to formulate clinical recommendations on this topic.

Compliance With Biochemical Objectives in Patients on Renal Replacement Therapy Before Kidney Transplantation in Mexico.

OBJECTIVES: The biochemical conditions in which patients arrive before renal transplantation (RT) are rarely evaluated; examples of them are found in the Dialysis Outcomes and Practice Patterns Study (DOPPS). The objective of our study was to ascertain the fulfillment of biochemical goals for patients on renal replacement therapy before RT. MATERIAL AND METHODS: Observational, retrospective study of patients who were on a RT protocol between 2012 and 2017 in 2 RT centers in Mexico. The records of 1188 patients with a history of RT and their lab results before transplantation were analyzed. Anthropometric values including hemoglobin, iron levels, calcium, phosphorus, parathyroid hormone, urea, creatinine, uric acid, and left ventricular ejection fraction were studied. All values were categorized as low, optimal, or high levels. RESULTS: The fulfillment of pretransplant biochemical objectives for elimination of azotemia (urea and creatinine) was achieved in 60% of the patients. Optimal values for calcium were found in 715 (64%) patients and optimal values for albumin were found in 690 (61.8%) patients. In the case of phosphorus, hemoglobin, uric acid, and parathyroid hormone, the optimal values were below 50%. CONCLUSIONS: It is essential to improve compliance with biochemical and clinical objectives for patients on renal replacement therapy (dialysis, hemodialysis) before RT. Only half of the variables were within the optimal range before surgical intervention took place.

Desenlaces obstétricos en mujeres embarazadas con enfermedad renal crónica y factores asociados / Obstetric outcomes in pregnant women with chronic kidney disease and associated factors

Resumen OBJETIVO: Identificar los factores asociados con los desenlaces fetales, maternos y renales en embarazadas con enfermedad renal crónica. MATERIALES Y MÉTODOS: Estudio observacional y prospectivo llevado a cabo en el Hospital de Ginecoobstetricia 4 del IMSS de 2016 a 2018 en pacientes embarazadas con enfermedad renal crónica, con parámetros bioquímicos (creatinina, urea) y desenlaces obstétricos; se excluyeron los casos incompletos. Por el tipo de población se usó estadística no paramétrica con mediana (tendencia central) y rango intercuartilar (dispersión). Para la comparación de medias se utilizó t de Student y Kruskal Wallis; los valores de p < 0.05 se consideraron estadísticamente significativos. Para establecer el riesgo se efectuó análisis bivariado. Se utilizó el programa estadístico SPSS 25. RESULTADOS: Se estudiaron 48 pacientes; de éstas 16 cursaron con preeclampsia. La cesárea fue la vía de finalización del embarazo más común en 32 de los 48 casos. En relación con los recién nacidos: 41 supervivieron, 22 de 41 fueron prematuros, 19 de 41 nacieron a término, 29 de 41 recién nacidos no experimentaron complicaciones. Se registró elevación de la creatinina de 0.28 mg/dL y descenso de la tasa de filtración glomerular de 9.67 mL/min. CONCLUSIONES: Se identificaron 4 factores. La maduración pulmonar y las enfermedades crónico-degenerativas representaron riesgo de prematurez. Los factores contibuyentes para el embarazo de término fueron: no cursar con preeclampsia y no tener eventos de hospitalización o infección. La enfermedad renal crónica influye de forma directa en desenlaces adversos para la madre y el feto; el embarazo influye en mayor deterioro renal.

Abstract OBJECTIVE: To know the factors associated with fetal, maternal and renal outcomes in known pregnant women with chronic kidney disease. MATERIALS AND METHODS: An observational, prospective study at the IMSS Hospital of Gynecobstetrics No. 4 from 2016 to 2018 of pregnant women with chronic kidney disease with biochemical parameters (creatinine, urea) and obstetric outcomes; Incomplete cases were excluded. For the type of population, non-parametric statistics were used with median (central tendency), interquartile range (dispersion), for the comparison of means, a student's "t" was used, with a significance of p < 0.05 and Kruskal Wallis. To establish risk, a bivariate analysis is performed. SPSS 25 statistical program. RESULTS: The obstetric results obtained were: 16/48 of the women with preeclampsia, caesarean section was the most common resolution in 32/48 cases. In relation to newborns, 41 survived, 22/41 with prematurity, 19/41 were full term, 29/41 newborns without complications. There was an elevation of 0.28 mg/dL creatinine and a decrease in the glomerular filtration rate of 9.67 mL/min. CONCLUSIONS: 4 factors were identified. Pulmonary maturation and chronic-degenerative diseases represented a risk for prematurity; Two influential factors for the termination of pregnancy were: not taking preeclampsia and having no hospitalization and/or infection events. chronic kidney disease directly influences both maternal and fetal adverse outcomes, and pregnancy also has an influence on greater renal impairment.

Alelos HLA más comunes y asociados con riesgo o protección en enfermedad renal crónica de etiología no determinada.

INTRODUCTION: Chronic kidney disease accounts for part of overall health expenditure; a potential etiology is related to variations, absence or presence of some human leukocyte antigen (HLA) alleles. METHOD: An analysis of HLA reports of 1965 kidney recipients with no determined etiology, and 1361 kidney donors was performed. It was carried out with Luminex based in cell flow fluorometry for the A, B, DRB1 and DQA loci. An analysis was performed with contingency tables in order to determine the odds ratio (OR) and confidence intervals (CI). Quantitative analysis was also carried out. RESULTS: Of the 101 alleles found, 13 showed association, 7 with risk for chronic kidney disease, with the most significant being HLA-DR17 with an OR of 3.91 (95 % CI = 2.96-5.17) and the one with the highest significance for protection being HLA-DR9, with an OR of 0.043 (95 % CI = 0.005-0.3224). CONCLUSIONS: It is necessary to understand that kidney diseases can be associated with yet unknown immune processes, where the association of the absence or presence of any allele should be known.

INTRODUCCIÓN: La enfermedad renal crónica representa parte del gasto en salud en general; una potencial etiología es la relacionada con variaciones, ausencia o presencia de algunos alelos del human leucocyte antigen (HLA). MÉTODO: Se realizó el análisis de 1965 reportes de HLA sin etiología determinada y de 1361 donadores renales. Se llevó a cabo tecnología Luminex con base en fluorimetría de flujo celular para los locus A, B, DRB1 y DQA. Se realizó análisis con tablas de contingencia para determinar razón de momios (RM) e intervalos de confianza (IC). Se efectuó análisis cuantitativo. RESULTADOS: De 101 alelos encontrados, 13 presentaron asociación, siete con riesgo para enfermedad renal crónica, de los cuales el más significativo fue HLA-DR17, con RM = 3.91 (IC 95 % = 2.96-5.17), y el de mayor significación de protección fue HLA-DR9, con RM = 0.043 (IC 95 % = 0.005-0.3224). CONCLUSIONES: Es necesario entender que las enfermedades renales pueden estar ligadas a procesos inmunológicos, en los que se tiene que conocer la asociación de la ausencia o presencia de algún alelo.
