Insulin and the kidneys: a contemporary view on the molecular basis.

Insulin is a hormone that is composed of 51 amino acids and structurally organized as a hexamer comprising three heterodimers. Insulin is the central hormone involved in the control of glucose and lipid metabolism, aiding in processes such as body homeostasis and cell growth. Insulin is synthesized as a large preprohormone and has a leader sequence or signal peptide that appears to be responsible for transport to the endoplasmic reticulum membranes. The interaction of insulin with the kidneys is a dynamic and multicenter process, as it acts in multiple sites throughout the nephron. Insulin acts on a range of tissues, from the glomerulus to the renal tubule, by modulating different functions such as glomerular filtration, gluconeogenesis, natriuresis, glucose uptake, regulation of ion transport, and the prevention of apoptosis. On the other hand, there is sufficient evidence showing the insulin receptor's involvement in renal functions and its responsibility for the regulation of glucose homeostasis, which enables us to understand its contribution to the insulin resistance phenomenon and its association with the progression of diabetic kidney disease.

Utilidad del citoquímico urinario en cuidados intensivos, una herramienta olvidada

El sedimento urinario es una herramienta utilizada hace tantos años para caracterizar manifestaciones renales de enfermedades primarias y secundarias, que es necesario realizar una estandarización y aprender a interpretar el mismo. En los pacientes ingresados a la unidad de cuidados intensivos, muchas veces no se realiza, o hay que tener en cuenta varios factores para su interpretación debido al estado hemodinámico del paciente a la filtración glomerular, la excreción tubular, la reabsorción de agua y los solutos además del equilibrio acido-base, los cuales pueden variar significativamente en pacientes en estado crítico con diferentes condiciones fisiopatológicas. Se presenta una revisión de las condiciones para la interpretación del urianálisis.

A urinary sediment is a tool used for years to characterize renal manifestations of primary and secondary diseases, which requires standardization and learning to interpret it. In patients admitted to the intensive care unit, it is often not performed, or several factors must be taken into account for its interpretation due to the patient's hemodynamic status, glomerular filtration, tubular excretion, water reabsorption, and solutes. In addition to the acid-base balance, which can vary significantly in critically ill patients with different pathophysiological conditions? A review of the conditions for the interpretation of urinalysis is presented.

Novel Biomarkers of Diabetic Kidney Disease.

Diabetic kidney disease (DKD) is a highly prevalent condition worldwide. It represents one of the most common complications arising from diabetes mellitus (DM) and is the leading cause of end-stage kidney disease (ESKD). Its development involves three fundamental components: the hemodynamic, metabolic, and inflammatory axes. Clinically, persistent albuminuria in association with a progressive decline in glomerular filtration rate (GFR) defines this disease. However, as these alterations are not specific to DKD, there is a need to discuss novel biomarkers arising from its pathogenesis which may aid in the diagnosis, follow-up, therapeutic response, and prognosis of the disease.

Bloqueo del eje renina angiontensina aldosterona (RAAS) en la enfermedad renal diabética. Más allá del control de la hipertensión arterial / Renin angiotensin aldosterone system (RAAS) and its suppression in diabetic kidney disease. Control of arterial hypertension and beyond

La enfermedad renal diabética (ERD) es una comorbilidad con alta prevalencia a nivel mundial, siendo una de las complicaciones más frecuentes de la diabetes mellitus (DM). La ERD se relaciona con complicaciones cardiovasculares y progresión de la enfermedad renal crónica (ERC), por ello la identificación de factores modificables, como el control de la presión arterial, es uno de los pilares más importantes en el manejo integral. En esta revisión hacemos un recorrido sobre el papel de la hipertensión y el bloqueo del eje renina angiotensina aldosterona (RAAS) en el curso de la ERD y las estrategias terapéuticas orientadas a la reducción de la presión arterial (PA), el bloqueo RAAS y el impacto en resultados renales y cardiovasculares. El objetivo de este artículo es hacer una revisión de las intervenciones más importantes que actúan bloqueando el eje renina angiotensina aldosterona (RAAS) y determinar si estas medidas en los pacientes con ERD, solo tienen impacto en el control de la presión arterial o si también son estrategias de nefro y cardio-protección. Conclusión: La ERD es una de las complicaciones más frecuentes de la diabetes mellitus (DM). El control de la PA sigue siendo un pilar fundamental para lograr estos objetivos. Los bloqueadores del RAAS (iECAS y BRAs) son los antihipertensivos de elección con efecto terapéutico por el bloqueo RAAS y esto les permite tener además del control de la PA, efectos nefroprotectores y cardioprotectores importantes en pacientes con ERD, sobre todo cuando hay la presencia de albuminuria. Evaluamos que además de los inhibidores de la enzima convertidora de angiotensina (iECAs) y los bloqueadores del receptor de angiotensina (BRAs), vienen tomando importancia los antagonistas selectivos del receptor mineralocorticoide (ARM) como Finerenona.

Diabetic kidney disease (DKD) is a comorbidity with a high worldwide prevalence, and one of the most frequent complications of diabetes mellitus (DM). CKD is related to cardiovascular complications and the progression of chronic kidney disease (CKD), therefore the identification of modifiable factors, such as blood pressure control, is one of the most important pillars in comprehensive management. In this review, we will analyze the role of hypertension and the renin-angiotensin-aldosterone system (RAAS) and its suppression in the course of CKD, and therapeutic strategies aimed at reducing blood pressure (BP), RAAS blockade, and the impact on renal and cardiovascular outcomes. The objective of this article is to review the most important interventions that act by blocking the renin-angiotensin-aldosterone system (RAAS) and to determine if these measures in patients with CKD only have an impact on blood pressure control or if they are also nephron and cardio-protective strategies. Conclusion: DKD is one of the most frequent complications of diabetes mellitus (DM). BP control continues to be a fundamental pillar to achieve these objectives. RAAS blockers (iECAS and ARBs) are the first-line antihypertensive with a therapeutic effect due to RAAS blockade and this allows them to have, in addition to BP control, important nephroprotective and cardioprotective effects in patients with CKD, especially when there is albuminuria. We evaluated that in addition to angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), selective mineralocorticoid receptor antagonists (MRA) such as Finerenone are gaining importance.

Critically Ill Patients with Renal Hyperfiltration: Optimizing Antibiotic Dose.

Renal hyperfiltration (RHF) is a prevalent phenomenon in critically ill patients characterized by augmented renal clearance (ARC) and increased of elimination of renally eliminated medications. Multiple risk factors had been described and potential mechanisms may contribute to the occurrence of this condition. RHF and ARC are associated with the risk of suboptimal exposure to antibiotics increasing the risk of treatment failure and unfavorable patient outcomes. The current review discusses the available evidence related to the RHF phenomenon, including definition, epidemiology, risk factors, pathophysiology, pharmacokinetic variability, and considerations for optimizing the dosage of antibiotics in critically ill patients.

Enfermedad renal diabética: puesta al día / Update on diabetic kidney disease

Introducción: La Diabetes Mellitus (DM) es una enfermedad inflamatoria sistémica de alta prevalencia e incidencia a nivel mundial. Dentro de las complicaciones crónicas, la enfermedad renal diabética es una de las más frecuentes y que marca el pronóstico. Objetivos: El objetivo de este artículo es hacer una revisión actualizada de la enfermedad renal diabética, a la luz de los cambios en los paradigmas que se han generado en los últimos años con respecto a sus nuevas definiciones, el papel de la inflamación en su desarrollo, la gestión del riesgo cardiovascular y los nuevos tratamientos. La enfermedad renal diabética puede presentarse en aproximadamente el 30-50% de la población con diabetes mellitus tipo 1 o 2 alrededor del mundo. En la patogénesis y progresión de esta condición se distinguen tres ejes fundamentales el hemodinámico, metabólico e inflamatorio. Es importante siempre hacer gestión del riesgo cardiovascular. El diagnóstico se debe hacer con el cálculo de la tasa de filtrado glomerular y la relación albuminuria / creatinuria en muestra ocasional. Los objetivos en el tratamiento deben ser: el control metabólico, reducir o enlentecer la progresión de la enfermedad renal y disminuir los desenlaces cardiovasculares. Conclusión: El tratamiento de la ERD debe ser holístico, desde intervenciones no farmacológicas, como la modificación de los estilos de vida, hasta los nuevos medicamentos como el uso de inhibidores SGLT-2, Agonistas del receptor GLP-1 y el uso antagonistas selectivos del receptor mineralocorticoide como finerenona. El futuro es promisorio.

Introduction: Diabetes mellitus (DM) is a systemic inflammatory disease of high prevalence and incidence worldwide. Among the chronic complications, diabetic kidney disease is one of the most frequent and determines the prognosis. Objectives: The objective of this article is to make an updated review of diabetic kidney disease, in light of the changes in the paradigms that have been generated in recent years concerning to the new definitions, the role of inflammation-causing disease, cardiovascular risk management, and the new treatments. Diabetic kidney disease can present in approximately 30-50% of the population with diabetes mellitus type 1 or 2 around the world. In the pathogenesis and progression of this condition, three fundamental axes are distinguished: the hemodynamic, the metabolic, and the inflammatory. It is important to manage cardiovascular risk. The diagnosis must be made by calculating the glomerular filtration rate and the albuminuria/creatinuria ratio in a random urine sample. The objectives of the treatment should be: metabolic control, reduce or slow the progression of kidney disease and improve cardiovascular outcomes. Conclusion: The treatment of diabetic kidney disease should be holistic, from non-pharmacological interventions, such as lifestyle changes, to new medications such as the use of SGLT-2 inhibitors, GLP-1 receptor agonists, and the use of selective mineralocorticoid receptor antagonists such as finerenone. The future is promising.

Molecular Mechanisms of Diabetic Kidney Disease.

The inflammatory component of diabetic kidney disease has become of great interest in recent years, with genetic and epigenetic variants playing a fundamental role in the initiation and progression of the disease. Cells of the innate immune system play a major role in the pathogenesis of diabetic kidney disease, with a lesser contribution from the adaptive immune cells. Other components such as the complement system also play a role, as well as specific cytokines and chemokines. The inflammatory component of diabetic kidney disease is of great interest and is an active research field, with the hope to find potential innovative therapeutic targets.

Prevalence of Chronic Infection by Hepatitis C Virus in Asymptomatic Population With Risk Factors in Cartagena, Colombia.

Introduction: Infection by the hepatitis C virus (HCV) is an important cause of chronic liver disease, considered a public health problem worldwide with high morbidity and mortality due to limited access to diagnostic tests in developing countries. Only a small percentage know their infection status and receive timely treatment. It is critical to make diagnostic tests for HCV infection accessible and to provide timely treatment, which not only reduces the spread of infection but also stops the progression of HCV disease without symptoms. Objective: To determine the prevalence of chronic infection by HCV in patients with risk factors by using rapid tests in Cartagena, Colombia, and describe their epidemiological characteristics. Methodology: A cross-sectional descriptive observational study was carried out on asymptomatic adults with risk factors for HCV infection in the city of Cartagena between December 2017 and November 2019. A rapid immunochromatographic test was performed to detect antibodies, characterizing the population. Results: In total, 1,023 patients were identified who met the inclusion criteria, 58.5% women and 41.4% men, obtaining nine positive results, confirming chronic infection with viral load for HCV, finding seven cases of genotype 1b and two genotype 1a. Conclusion: In our study, a prevalence of hepatitis C infection of 0.9% was found in asymptomatic individuals with risk factors, which allows us to deduce that the active search for cases in risk groups constitutes a pillar for the identification of the disease, the initiation of antiviral therapy, and decreased morbidity and mortality.

Atypical hemolytic uremic syndrome in the Colombian Caribbean: its particular characteristics.

INTRODUCTION: Atypical hemolytic uremic syndrome (aHUS) is a rare and genetically mediated systemic disease most often caused by uncontrolled and chronic complement activation that leads to systemic thrombotic microangiopathy, renal and extra-renal damage. MATERIALS AND METHODS: This is descriptive, retrospective and multicenter study, which reports demographic, clinical, laboratory, and genetic characteristics, as well as their treatment response and outcome of 20 aHUS patients diagnosed between 2014 and 2018. RESULTS: Most patients were female adults (75%) and 30% were associated to pregnancy/postpartum, 15% to autoimmune disease, and 65% to infections. Gastrointestinal involvement (75%) was the most frequent extra-renal organ damage. Antenatal mortality and mortality rate were 5% and 10%, respectively. 25% of the patients progressed to end-stage renal disease. In 4/8 of patients treated within 1 week of presentation, eculizumab treatment restored multi-organ function after 4 weeks of treatment. CFH (37%) and CFI (25%) mutations were the most frequent. CONCLUSION: This is the first series of aHUS cases of Colombian Caribbean region which reports the clinical and epidemiological characteristics of this condition in this region.

Dipeptidyl Peptidase-4 Inhibitors and Diabetic Kidney Disease: A Narrative Review.

Diabetic kidney disease is one of the most frequent complications in patients with diabetes mellitus and affects morbidity and mortality. The recent therapies include oral hypoglycemic drugs that, in addition to optimizing glycemic control and reducing the risk of hypoglycemia, may affect the development and progression of diabetic kidney disease; these novel therapies include inhibitors of the enzyme dipeptidyl peptidase 4 (DPP-4), a group of oral hypoglycemic therapeutic agents that act at the level of the incretin system. DPP-4 inhibitors show additional pleiotropic effects in in vitro models, reducing inflammation, fibrosis, and oxidative damage, further suggesting potential kidney protective effects. Although existing trials suggest a possible benefit in the progression of diabetic kidney disease, further studies are needed to demonstrate kidney-specific benefits of DPP-4 inhibitors.

Enfermedad por neumococo: desafíos actuales en los pacientes con enfermedad renal crónica y diabetes mellitus

La enfermedad por neumococo se defino como cualquier infección causada por la bacteria Streptococcus pneumoniae; esta se denomina invasiva cuando el aislamiento de este microorganismo se confirma en sitios corporales que son normalmente estériles, tales como la sangre y el líquido cefalorraquídeo, y no invasiva cuando la infección se produce en sitio corporales que normalmente no son estériles. La enfermedad renal crónica y la diabetes mellitus son factores de riesgo importantes para el desarrollo de enfermedad neumocócica debido a su estado de inmunosupresión, por lo que la vacunación antineumocócica es una medida preventiva fundamental en los pacientes que padecen estas condiciones.

Pneumococcal disease is defined as any infection caused by the bacteria Streptococcus pneumoniae; it is called invasive when the isolation of this microorganism is confirmed in sites of the body that are normally sterile, such as blood and cerebrospinal fluid, and non-invasive when the infection occurs in sites of the body that are normally non-sterile. Chronic kidney disease and diabetes mellitus are important risk factors for the development of pneumococcal disease due to their status of immunosuppression;therefore, anti-pneumococcal vaccination is a fundamental preventive measure in patients who suffer from these conditions.

Proteoma urinario en la enfermedad renal diabética. Estado del arte

La enfermedad renal diabética (ERD) es la principal complicación microvascular de los pacientes con diabetes mellitus; esta es una entidad que genera un aumento significativo en la mortalidad de origen cardiovascular de este grupo de pacientes, aunque su diagnóstico temprano impacta de forma significativa en la evolución a enfermedad renal terminal y, por lo tanto, en la mortalidad. La detección de albuminuria en la orina y el deterioro de la tasa de filtración glomerular estimada son las principales técnicas diagnósticas que se utilizan en la práctica clínica para establecer la presencia de ERD; sin embargo, estas tienen limitaciones y por lo tanto es importante resaltar que el daño renal suele ser irreversible una vez están presentes. Durante los últimos años, numerosos estudios se han enfocado en detectar nuevos biomarcadores para detectar ERD y es aquí donde aparece como nueva herramienta la proteómica urinaria, una tecnología emergente que permite identificar en una muestra de orina proteínas que sugieren la presencia de esta enfermedad de manera temprana. Asimismo, el descubrimiento de biomarcadores basados en proteómicos representa una estrategia novedosa para mejorar el diagnóstico, pronóstico y tratamiento de la nefropatía diabética; sin embargo, los enfoques basados en la proteómica aún no están disponibles en la mayoría de los laboratorios de química clínica.

Diabetic kidney disease (DKD) is the main microvascular complication in patients with diabetes mellitus; it is an entity that generates a significant increase in mortality of cardiovascular origin in this group of patients, although its early diagnosis has a significant impact on the evolution to end-stage kidney disease and, therefore, on mortality. The detection of albuminuria in urine and the deterioration of the estimated glomerular filtration rate are the main diagnostic techniques that are used in clinical practice to establish the presence of DKD; however, they have limitations and therefore it is important to note that kidney damage is usually irreversible once they are present. Over the last few years, numerous studies have focused on the discovery of new biomarkers to detect DKD and this is where the urinary proteomics appears as a new tool, an emerging technology that allows the identification of proteins in a urine sample that strongly suggest the early presence of this disease. Likewise, the discovery of proteomic-based biomarkers represents a novel strategy to improve the diagnosis, prognosis and treatment of diabetic nephropathy; however, proteomics-based approaches are not yet available in the majority of clinical chemistry laboratories.
