Protein-energy wasting (PEW) and poor health-related quality of life (HRQoL) are independently associated with morbi-mortality in continuous ambulatory peritoneal dialysis (CAPD). PEW may reduce HRQoL; however, we hypothesized HRQoL is affected differentially by PEW degrees or by individual criteria of nutritional status. AIM: To evaluate HRQoL according to PEW severity and nutritional status indicators in CAPD. This is a cross-sectional study in 151 patients. Subjective global assessment (SGA) was employed, and nutritional status classified as normal, mild-moderate PEW, and severe PEW. HRQoL was evaluated using Kidney Disease Quality of Life Short Form™, including physical (PCS), mental (MCS) and kidney disease (KDCS) components, and their subscales. Dietary intake, anthropometric and biochemical variables were measured. Forty-six percent of patients were well-nourished, 44% had mild-moderate PEW, and 10% severe PEW. Compared with well-nourished patients, those with mild-moderate (p=0.06) and severe (p=0.005) PEW had lower HRQoL score [68 (52-75), 55 (45-72), 46 (43-58), respectively]. PCS, MCS, and KDCS and their subscales had lower values as PEW was more severe. Patients with obesity and hypoalbuminemia had significantly lower HRQoL overall and component scores than their counterparts. Dietary intake was not associated with quality of life. In multivariate analysis obesity, PEW (by SGA), hypoalbuminemia, and low educational level predicted poor HRQoL (χ2 58.2, p

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.Qualitative exploratory study, phenomenological through semi-structured telephone interview.A priori sampling was carried out with patients on APD with remote monitoring and telephone follow-up, in 13 hospitals in Mexico.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.

To determine the evolution, associated factors and the outcomes of transplanted people one year after the evolution of a cohort in Mexico.Kidney transplant cohort from 2013 to 2017 in Mexico. 1118 patients were analyzed. Five outcomes were studied: overall survival, kidney graft, patient survival, delayed function, and acute dysfunction. Kaplan-Meier was used for kidney graft survival. For risk, bivariate and multivariate analyzes were performed with a significant value of p0.05.Of the 1118 kidney transplant patients, 57 (5.09%) had kidney graft loss, 52 (4.65%) died during the one-year follow-up; survival of the patient of 95.35% and of the graft 90.25%.The risk factors for the outcomes were transplantation from a deceased donor, recipient over 50 years of age and use of polyclonal agents. Infections and age are related to the death of the patient.Determinar la funcionalidad del injerto renal a 1 año en una cohorte retrospectiva en México.Cohorte de trasplante renal de 2013 a 2017 en México.

Para la supervivencia del injerto renal se usó Kaplan-Meier. Para el riesgo se realizó análisis bivariado y multivariado con valor significativo p0.05.De los 1118 pacientes con trasplante renal, 57 (5.09%) tuvieron pérdida del injerto, 52 (4.65 %) fallecieron durante el año de seguimiento; la supervivencia del paciente fue del 95.35% y la supervivencia del injerto fue del 90.25%.Los factores de riesgo para los desenlaces fueron trasplante de donante fallecido, receptor mayor de 50 años y uso de agentes policlonales. Las infecciones y la edad están relacionadas con la muerte del paciente.

There are very few data on analytical biomarker levels in children with congenital heart disease (CHD) before and after cardiopulmonary bypass surgery. We conducted a preliminary study in the Pediatric Hospital of Medical Center IMSS Mexico, to evaluate plasma levels of endothelin-1 (ET-1) and circulating endothelial progenitor cells (CPEC) before and after correction surgery. 56 patients were included: 41 with CHD that required CPB and 15 controls with surgery other than CPB, which were stratified by age (infants, preschool-age-children, and school-age-children). Samples of peripheral blood were taken 24h before and 48h after surgery, cytokine levels (TNF/IL-1β/IL-6/IL-8/IL-10 and IL-12p70) and brachial-artery-flow-mediated dilation (BAFMD) were explored too. Demographic and clinical data were collected. BAFMD was evaluated by-Doppler-ultrasound, the percentage (%) and absolute number (N) of CPEC [CEC and EPC], ET-1 and cytokines concentrations were measured by flow-cytometry, radioimmunoassay and a Bead-Array-cytometric-system, respectively. The% and N of CEC[CD34 + / CD146 + / VEGFR2 + / CD133−] increased in infants versus their control group; and EPC[CD34 + / CD146 + / VEGFR2 + / CD133 +] were higher in the control group of infants versus patients. ET-1 levels were higher in patients than in controls (p = 0.002). N-CEC showed differences between 24 and 48 hours; BAFMD in CPB-preschool at 24H and 48H showed a significant difference. Higher levels of IL-6 and IL-8 were detected in CPB-school-age at 48H. This pilot study observed a significant increase in the levels of CEC and ET-1. To validate these data, subsequent studies should increase the sample size.

End-stage renal disease (ESRD) patients have an elevated risk of cardiovascular (CV) complications including acute myocardial infarction (AMI); endothelial dysfunction and accumulation of uremic toxins have been associated with such CV-events. To explore which molecular pathways are involved in this CV-complication and the effects of the uremic serum on gene expression, an endothelial dysfunction model was studied through microarrays and pathway analysis. mRNA was isolated of human coronary arterial endothelial cells (HCAEC) primary cultures supplemented with 20% uremic serum from two groups of patients, USI: ESRD-patients; UCI: ESRD-AMI-patients. Affymetrix GeneChip® microarray and the LIMMA-package (Linear Models for Microarray Data) of the Bioconductor sofware17 was implemented to identify relevant DEGs between the two groups of uremic patients. Protein-protein interaction networks and pathway analysis were made to analyze the interaction and expression tendency of differentially expressed genes. 100 differentially expressed genes were identified from two data sets triggered by uremic state using bioinformatics, from 16,607. After in a new cohort, 30 genes were overexpressed in UCI group, which we identified 500 ontological genetic terms and one KEGG-pathway with p < 0.05. The metabolic pathway significantly represented was the MAPK signaling pathway. Network analysis showed six genes (PTGS2, SELE, ICAM1, HMOX1, EGR1, and TLR2) that represent potential markers for ESRD with AMI, as an approximation to their underlying mechanisms. The results obtained suggest that uremic toxins in patients with ESRD can alter HCAEC and modify the gene expression profile, which could have an impact on the development of cardiovascular complications in these patients.

BACKGROUND The presence of acute renal injury has been associated with increased cardiovascular morbidity and mortality (sudden death and arrhythmias). OBJECTIVE To know the frequency of heart rhythm disorders documented by Holter in patients in need of intermittent hemodialysis due to acute renal injury. MATERIAL AND METHODS A prospective observational study was conducted including patients with a diagnosis of acute renal injury who received intermittent hemodialysis; demographic, clinical and laboratory data were collected from 28 patients. Monitoring was carried out through Holter before, during and after the hemodialysis session. Nonparametric statistics were used, with a significant value of p < 0.05. Risks were established with logistic regression. RESULTS There was a significant difference in supraventricular extra systoles (82.1% vs. 57.1%), ventricular extra systoles (26.7% vs. 3.6%), and supraventricular tachycardia (6.7% vs. 3.6%). The rest of the rhythm alterations without significance. CONCLUSIONS Intermittent hemodialysis is a factor associated with the appearance of heart rhythm disorders. The death of patients with acute renal injury and substitution was related to ventricular extra systole detected by transhemodialysis Holter.

espanolIntroduccion: La enfermedad renal cronica representa parte del gasto en salud en general; una potencial etiologia es la relacionada con variaciones, ausencia o presencia de algunos alelos del human leucocyte antigen (HLA). Metodo: Se realizo el analisis de 1965 reportes de HLA sin etiologia determinada y de 1361 donadores renales. Se llevo a cabo tecnologia Luminex con base en fluorimetria de flujo celular para los locus A, B, DRB1 y DQA. Se realizo analisis con tablas de contingencia para determinar razon de momios (RM) e intervalos de confianza (IC). Se efectuo analisis cuantitativo. Resultados: De 101 alelos encontrados, 13 presentaron asociacion, siete con riesgo para enfermedad renal cronica, de los cuales el mas significativo fue HLA-DR17, con RM = 3.91 (IC 95 % = 2.96-5.17), y el de mayor significacion de proteccion 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 inmunologicos, en los que se tiene que conocer la asociacion de la ausencia o presencia de algun alelo. EnglishIntroduction: 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.
