[Renoprotection. About World Kidney Day]. / Renoprotección. A propósito del Día Mundial del Riñón.

The World Kidney Day was founded in 2003 by doctor Joel D. Kopple, American nephrologist, who in the session in the Congress of the International Federation of Kidney Foundations explained the need to implement the celebration on a day that alludes to this organ, in order to direct preventive actions for kidney disease and raise awareness in the medical community and the general population on the importance of caring for the kidneys. 3 years later, the proposal was accepted and as of 2006 World Kidney Day is celebrated. The diffusion is found throughout the world and in each place there are talks, courses, workshops, cultural activities and even marathons related to the prevention, diagnosis and treatment of kidney disease. Chronic kidney disease (CKD) is a disorder with a chronic, degenerative, and lethal evolution. Managing CKD requires a large amount of human, financial, and infrastructure resources. It impairs the quality of life and negatively affects survival. On the other hand, it leads to dialysis and kidney transplant treatments, which are expensive enough to put any health institution at financial risk, especially those most vulnerable. The main idea of these non-profit international organizations is to promote the well-being and improve the quality of life of people with CKD with and without dialysis, and to promote kidney transplantation as the first treatment option.

El Día Mundial del Riñón se fundó en el año 2003 por el doctor Joel D. Kopple, nefrólogo norteamericano, quien en el pleno del Congreso de la Federación Internacional de Fundaciones Renales expuso la necesidad de implementar la celebración en un día que aludiera a este órgano, con el fin de dirigir acciones de prevención para la enfermedad renal y concientizar a la comunidad médica y a la población en general de la importancia de cuidar los riñones. Tres años después, la propuesta fue aceptada y a partir del 2006 se celebra el Día Mundial del Riñón. La difusión se encuentra en todo el mundo y en cada lugar se desarrollan pláticas, cursos, talleres, actividades culturales y hasta maratones relacionados con la prevención, el diagnóstico y el tratamiento de la enfermedad renal. La enfermedad renal crónica (ERC) es un trastorno de evolución crónica, degenerativa y letal. Su atención demanda gran cantidad de recursos humanos, financieros y de infraestructura. Es una enfermedad que deteriora la calidad de vida y afecta negativamente la supervivencia. Por otra parte, conduce a realizar tratamientos costosos de diálisis y trasplante renal que ponen en riesgo financiero a cualquier institución de salud, sobre todo a aquellas más vulnerables. La idea principal de estos organismos internacionales sin fines de lucro es promover el bienestar y mejorar la calidad de vida de las personas con ERC con y sin diálisis, y promover el trasplante renal como primer opción de tratamiento.

Unmet Needs of CKD in Latin America: A Review from Expert Virtual Working Group.

Chronic kidney disease (CKD) represents a major challenge for Latin American (LatAm) because of its epidemic proportions. Therefore, the current status and knowledge of CKD in Latin America is not clearly understood. Moreover, there is a paucity of epidemiologic studies that makes the comparison across the countries even more difficult. To address these gaps, a virtual kidney expert opinion meeting of 14 key opinion leaders from Argentina, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Guatemala, Mexico, and Panama was held in January 2022 to review and discuss the status of CKD in various LatAm regions. The meeting discussed the following: (i) epidemiology, diagnosis, and treatment of CKD, (ii) detection and prevention programs, (iii) clinical guidelines, (iv) state of public policies about diagnosis and management of chronic kidney disease, and (v) role of innovative therapies in the management of CKD. The expert panel emphasized that efforts should be made to implement timely detection programs and early evaluation of kidney function parameters to prevent the development or progression of CKD. Furthermore, the panel discussed the importance of raising awareness among health care professionals; disseminating knowledge to the authorities, the medical community, and the general population about the kidney and cardiovascular benefits of novel therapies; and the need for timely updating of clinical practice guidelines, regulatory policies, and protocols across the region.

Documento de consenso sobre el uso de iSGLT2 en pacientes con enfermedad renal crónica y diabetes.

La enfermedad renal crónica (ERC) del paciente diabético es frecuentemente una consecuencia directa de la diabetes mellitus (DM) de larga evolución y se la conoce como nefropatía diabética. En México cerca del 50% de los pacientes en terapia sustitutiva de la función renal tienen ERC por DM, y este porcentaje podría aumentar en los próximos años. Nuevas opciones terapéuticas, combinadas con cambios en el estilo de vida, han mejorado el control de la glucemia y pueden contribuir sustancialmente a retrasar la aparición o la progresión a estadios avanzados de la ERC. Las sociedades científicas internacionales han elaborado guías clínicas para el diagnóstico y manejo de la nefropatía diabética, sin embargo, en algunos puntos estas recomendaciones no se adaptan a la realidad mexicana. Se presentan las conclusiones de un consenso realizado por especialistas mexicanos sobre diabetes y ERC, con especial énfasis en el uso de los inhibidores del cotransportador de sodio-glucosa.Chronic kidney disease (CKD) in the diabetic patient is mainly a consequence of long-term diabetes mellitus itself. In Mexico approximately 50% of patients on dialysis are diabetics and this will could increase in the coming years. New therapeutic options available, combined with lifestyle changes, have improved glycemic control and may contribute to delay the onset as well as the progression of CKD. International scientific societies have developed clinical guidelines for the diagnosis and management of CKD in diabetics, although in some points, these recommendations are not adapted to the Mexican reality. We hereby present the conclusions of the consensus reached by Mexican specialists on diabetic nephropathy.

Latin American Expert Consensus for Comprehensive Management of Type 2 Diabetes from a Metabolic-Cardio-Renal Perspective for the Primary Care Physician.

Growing scientific evidence from studies on type 2 diabetes (T2D) has recently led to a better understanding of the associated metabolic-cardio-renal risks. The large amount of available information makes it essential to have a practical guide that summarizes the recommendations for the initial management of patients with T2D, integrating different aspects of endocrinology, cardiology, and nephrology. The expert consensus presented here does not attempt to summarize all the evidence in this regard but rather attempts to define practical summary recommendations for the primary care physician to improve the clinical prognosis and management of patients with T2D, while ensuring economic sustainability of health systems, beyond glycemic control.

La disminución de triyodotironina se asocia con la elevación del péptido natriurético cerebral N-terminal y con la mortalidad en pacientes en diálisis / Low triiodothyronine is associated with elevation of N-terminal pro-brain natriuretic peptide (NT-proBNP) and mortality in dialysis patients

Antecedentes: La disminución de hormonas tiroideas (HT) y el daño miocárdico son frecuentes en pacientes en diálisis y están asociados con la mortalidad. Sin embargo, poco se conoce de la importancia de las HT como factor de daño miocárdico, como se ha descrito en las enfermedades tiroideas primarias. El objetivo de este estudio fue explorar si existe interacción entre la disminución de triyodotironina total (tT3) y los marcadores de daño miocárdico y la relación de esta interacción entre ambos con la mortalidad, para establecer si el daño cardiovascular es el vínculo entre la disminución de HT y el riesgo de muerte en pacientes con ERC en diálisis. Material y métodos: Se estudiaron los niveles plasmáticos de HT, de marcadores de nutrición, inflamación y de daño al miocardio en 296 pacientes en diálisis peritoneal o en hemodiálisis, a los que se vigiló por 16 meses para conocer la asociación de las variables bioquímicas con la mortalidad. Resultados: En el 45% de los pacientes se encontró tT3 disminuida, lo cual tuvo correlación inversa con la proteína C reactiva (PCR) y con el NT-proBNP y directa con la albúmina y la transferrina. La diabetes, la PCR y la tT3 fueron factores de riesgo para la mortalidad por cualquier causa y la PCR, el NT-proBNP y la tT3 para mortalidad cardiovascular. Conclusiones: Los niveles bajos de tT3 son frecuentes en pacientes en diálisis, se asocian con inflamación, desnutrición y daño miocárdico: este último puede ser el vínculo entre la disminución de HT y la mortalidad por cualquier causa y la mortalidad cardiovascular (AU)

Background: Low thyroid hormone (TH) levels and myocardial damage are common in dialysis patients and are associated with mortality. However, little is known about the role of THs on myocardial damage as has been described in primary thyroid diseases. The aim of this study was to explore the potential relationship between low total triiodothyronine (total T3) and biomarkers of myocardial damage and the effect of their interaction on mortality, to ascertain if cardiovascular damage is the link between low THs and the risk of death in dialysis patients with CKD. Material and methods: TH plasma levels, nutritional markers, inflammation and myocardial damage were studied in 296 patients undergoing peritoneal dialysis or haemodialysis, who were followed up for 16 months to ascertain the association between biochemical variables and mortality. Results: Low total T3 levels were found in 45% of patients, which was inversely correlated with C-reactive protein (CRP) and NT-proBNP, and directly correlated with albumin and transferrin. Diabetes, CRP and total T3 were risk factors for all-cause mortality, and CRP, NT-proBNP and total T3 for cardiovascular mortality. Conclusions: Low total T3 levels are common in dialysis patients and are associated with inflammation, malnutrition and myocardial damage. The latter may be the link between low THs and all-cause and cardiovascular mortality (AU)

[Current status of alternative therapies renal function at the Instituto Mexicano del Seguro Social]. / Estado actual de las terapias sustitutivas de la función renal en el Instituto Mexicano del Seguro Social.

BACKGROUND: The IMSS performs systematically the data updating of patients with renal replacement therapy (RRT) by an electronic record management referred as: Census patients with Chronical Renal Failure (CIRC) which aims to meet the prevalence of patients with chronic renal failure and the behavior of RRTat the IMSS. METHODS: A retrospective study includes 212 secondary hospitals with dialysis programs, with both pediatric and adult patients. CIRC data obtained from January to December 2014, number and nominal bonds of peritoneal dialysis (PD) and hemodialysis (HD). Prevalence of patients and therapies by delegation, distribution by gender and age, cause of kidney disease, morbidity and mortality were identified. RESULTS: 55,101 patients, of whom 29,924 were male (54 %) and 25,177 women (46 %), mean age was 62.1 years (rng: 4-90); 20,387 were pensioners (36.9 %). The causes of renal failure were: diabetes 29,054 (52.7 %), hypertension 18,975 (34.4 %), chronic glomerulopathies 3,951 (7.2 %), polycystic kidneys 1,142 (2.1 %), congenital 875 (1.6 %) and other 1,104 (2 %). HD was given in 41 % of patients, and the remaining 59 % DP; the annual cost was 5,608,290,622 pesos. CONCLUSIONS: The increased prevalence of diabetes mellitus and hypertension affect the onset of RRT, which show a catastrophic financial outlook for the Institute.

Introducción: el IMSS realiza de manera sistemática la actualización de datos de los pacientes en terapias sustitutivas de la función renal (TSFR) mediante un registro electrónico denominado: Censo de administración de pacientes con Insuficiencia Renal Crónica (CIRC), cuyo objetivo es conocer la prevalencia de pacientes con insuficiencia renal crónica y el comportamiento de las TSFR en el IMSS. Métodos: estudio retrospectivo, incluye 212 hospitales de segundo nivel con programas de diálisis, pacientes pediátricos y adultos. Datos obtenidos del CIRC de enero a diciembre de 2014, cédulas numeral y nominal de diálisis peritoneal (DP) y hemodiálisis (HD). Se identifica prevalencia de pacientes y terapias por delegación, distribución por género y edad, causa de la enfermedad renal, la morbilidad y mortalidad. Resultados: 55 101 pacientes, de los cuales fueron 29 924 masculinos (54 %) y 25 177 femeninos (46 %); edad promedio 62.1 años (rng: 4 a 90); pensionados 20 387 (36.9 %). Las causas de la insuficiencia renal fueron: diabetes 29 054 (52.7 %), hipertensión arterial 18 975 (34.4%), glomerulopatías crónicas 3951 (7.2 %), riñones poliquísticos 1142 (2.1 %), congénitos 875 (1.6 %), y otras 1104 (2 %). La HD se otorgó en 41 % de los pacientes y la DP al 59 % restante; el costo anual fue de 5 608 290 622 pesos. Conclusiones: la prevalencia incrementada de diabetes mellitus e hipertensión arterial repercuten en el inicio de una TSFR, las cuales muestran un panorama financiero catastrófico para el Instituto.

Tratamiento de la hipertensión arterial en presencia de enfermedad renal crónica / Treatment of hypertension in CKD patient

La mejoría en la sobrevida también ofrece una mayor posibilidad de padecer enfermedades crónicas degenerativas entre las que destacan la diabetes mellitus y la hipertensión arterial (HTA). La enfermedad renal crónica (ERC) actualmente constituye una pandemia y la HTA está presente en prácticamente todos los estadios de la ERC, el descontrol hipertensivo y la necesidad de ingerir más fármacos para obtener valores tensionales adecuados se hace más evidente a medida que progresa el estadio de la enfermedad. El enfermo renal presenta HTA de difícil control, en él se conjugan la activación adrenérgica, activación del sistema nervioso renina angiotensina aldosterona, la retención hídrica y mecanismos vasculares. El tratamiento antihipertensivo vigente en presencia de daño renal se enfoca a disminuir las cifras de presión arterial, disminuir el riesgo cardiovascular y brindar renoprotección, los antagonistas de receptores de angiotensina han demostrado ser la terapia farmacológica de elección independientemente de la enfermedad subyacente y del grado de proteinuria, la combinación con IECA no resulta en un mayor beneficio y si en efectos adversos graves como hipercalemia, inclusive potencialmente letales que incluyen síndrome de muerte súbita. El tratamiento de la HTA en la ERC deberá ir más allá de sólo la reducción de cifras de presión arterial, al considerar que en estos pacientes el riesgo cardiovascular se encuentra muy incrementado y el enlentecimiento de la progresión del daño renal es imperativo.

Improvement in survival involves a greater possibility of developing chronic degenerative diseases among which diabetes mellitus and hypertension stand out. Chronic kidney disease (CKD) is now a pandemic and hypertension is present in virtually all stages of CKD, the uncontrolled hypertension and the need to ingest more drugs to have adequate blood pressure values becomes more evident as disease stage progresses. Renal patients have high blood pressure difficult to control, and combine adrenergic activation, activation of the renin angiotensin aldosterone nervous system, water retention and vascular mechanisms. Current antihyperten-sive treatment when kidney damage is present focuses on reducing blood pressure, reducing cardiovascular risk and providing renoprotection; angiotensin receptor antagonists have been proven to be the pharmacological therapy of choice regardless of the underlying disease and the degree of proteinuria, the combination with ACEI does not result in a greater benefit but do produce serious adverse effects such as hyperkalemia, and even potentially lethal damage, including sudden death syndrome. Treatment of hypertension in CKD must go beyond just reducing blood pressure, considering that cardiovascular risk is greatly increased in these patients and that slowing the progression of kidney damage is imperative.

Reaching targets for mineral metabolism clinical practice guidelines and its impact on outcomes among Mexican chronic dialysis patients.

BACKGROUND AND AIMS: An increasing number of studies have been published concerning meeting targets of clinical guidelines for different aspects of the diagnosis and treatment of patients with end-stage renal disease. Most of these studies have shown that guideline recommendations are not always satisfied, and results outside target limits have been associated with high rates of mortality and morbidity. The objective of this study was to analyze the frequency of reaching mineral and bone metabolism-related guideline targets and its impact on clinical outcomes in Mexican chronic dialysis patients. METHODS: A cohort of prevalent peritoneal dialysis (PD) and hemodialysis (HD) patients were analyzed at baseline and followed for at least 16 months. Patients were on continuous ambulatory peritoneal dialysis (CAPD), automated peritoneal dialysis (APD), and HD and contracted HD modalities where patients received HD sessions outside institution facilities. RESULTS: We studied 753 patients. The percentage of patients within target limits for phosphorus was 35%, for calcium 32%, and for PTH 12%. The most frequent pattern was hyperphosphatamia, hypercalcemia, and low PTH. This was even more frequent in CAPD patients, probably due to the high percentage of diabetic patients. Hypercalcemia was found as an independent risk factor for mortality. CONCLUSIONS: The most important results suggest that guideline recommendations are not usually satisfied and that hypercalcemia, in addition to other traditional risk factors, is associated with high mortality rates. The study also detected some opportunities to improve the quality of treatment by reducing the calcium content of dialysis solutions and reducing the use of calcium carbonate as a phosphate binder.

[Pharmacological differences between inhibitor drugs of the renin-angiotensin aldosterone system]. / Inhibidores del sistema renina-angiotensina-aldosterona. Diferencias farmacológicas.

The activation of the renin-angiotensin-aldosterone cascade is a mechanism that generates high blood pressure. The structure has been identified and can be blocked through specific enzymatic pathways or receptors. We have a diversity of medications that act on this system. It is useful to develop the skill in clinical practice for selecting a drug from a wide variety. Renin-angiotensin system inhibitors share many pharmacological and pharmacokinetic characteristics but not all them are equivalent. Knowledge based on scientific evidence allows the clinician to choose the ideal drug for each patient.

La consulta de enfermería, propuesta de mejora en los programas de diálisis peritoneal / The nursing interview, apropossal for improving the peritoneal dialisis program

Resumen

La consultoría de enfermería (CE) en los programas de diálisis peritoneal (DP) es una herramienta indispensable en la práctica diaria, el papel de la enfermera en diálisis juega un papel determinante en el éxito de los programas y en la permanencia de los pacientes que requieren de estas terapias. La actuación del profesional de enfermería con un enfoque holístico es fundamental en coordinación y coparticipación con el equipo multidisciplinario. La CE basa sus acciones en procesos sistematizados y planificados, sustentados en el conocimiento científico y legal en donde el objetivo principal es promover la cultura del autocuidado con la participación del paciente de manera efectiva, segura y eficaz.

NT-proBNP, fluid volume overload and dialysis modality are independent predictors of mortality in ESRD patients.

BACKGROUND: N-terminal fragment of B-type natriuretic peptide (NT-proBNP) is a marker of both fluid volume overload and myocardial damage, and it has been useful as a predictor of mortality in patients with end-stage renal disease (ESRD). It has been suggested that continuous ambulatory peritoneal dialysis (CAPD), automated peritoneal dialysis (APD) and haemodialysis (HD) may have different effects on fluid volume and blood pressure control; however, whether the independent predictive value of NT-proBNP for mortality is preserved when analysed in conjunction with fluid overload and dialysis modality is not clear. METHODS: A prospective multicentre cohort of 753 prevalent adult patients on CAPD, APD and HD was followed up for 16 months. Plasmatic levels of NT-proBNP, extracellular fluid volume/total body water ratio (ECFv/TBW) and traditional clinical and biochemical markers for cardiovascular damage risk were measured, and their role as predictors of all-cause and cardiovascular mortality was analysed. RESULTS: NT-proBNP level, ECFv/TBW and other cardiovascular damage risk factors were not evenly distributed among the different dialysis modalities. NT-proBNP levels and ECFv/TBW were correlated with several inflammation, malnutrition and myocardial damage markers. Multivariate analysis showed that NT-proBNP levels and ECFv/TBW were predictors of both all-cause and cardiovascular mortality, independently of dialysis modality and the presence of other known clinical and biochemical risk factors. CONCLUSIONS: NT-proBNP is a reliable predictor of death risk independently of the effect of dialysis modality on fluid volume control, and the presence of other clinical and biochemical markers recognized as risk factors for all-cause and cardiovascular mortality. NT-pro-BNP is a good predictor of mortality independently of fluid volume overload and dialysis modality.
