Antidiabéticos orales y trastornos depresivos: ¿riesgo o protección? / Oral antidiabetics and depressive disorders: Risk or protection?

Introducción la diabetes mellitus y los trastornos del estado de ánimo son 2 entidades que se entrelazan entre sí con mecanismos fisiopatológicos en común. Los hipoglucemiantes orales son un pilar fundamental para obtener el control glucémico en los individuos diabéticos y, recientemente, la alta prevalencia de estas 2 patologías en un mismo paciente han hecho que los estudios clínicos se enfoquen en analizar el efecto de los hipoglucemiantes orales en los pacientes con diabetes mellitus tipo 2 y trastorno depresivo. Objetivo realizar una revisión de la literatura disponible sobre la medicación hipoglucemiante en el contexto de los pacientes con diabetes mellitus y trastorno depresivo. Conclusiones si bien los antidiabéticos orales han mostrado tener un efecto antidepresivo en ciertos modelos experimentales, en la práctica clínica la evidencia es escasa, pero llama particularmente la atención el menor riesgo de depresión con ciertos antidiabéticos dejando abierta las posibilidades de futuros estudios con la naturaleza adecuada que permita aclarar el efecto de los hipoglucemiantes orales en la población con diabetes mellitus y trastorno depresivo.

Introduction Diabetes mellitus and mood disorders are two entities that are intertwined with common pathophysiological mechanisms. Oral hypoglycemic agents are a fundamental pillar in obtaining adequate glucose control in diabetic individuals and, recently, the high prevalence of these two pathologies in the same patient have led clinical studies to focus on analyzing the effect of oral hypoglycemic agents in diabetics. patients with type 2 diabetes mellitus and depressive disorder. Objective To carry out a review of the available literature on hypoglycemic medication in the context of patients with diabetes mellitus and depressive disorder. Conclusions Although oral antidiabetics have been shown to have an antidepressant effect in certain experimental models, in clinical practice the evidence is scarce, but the lower risk of depression with certain antidiabetics is particularly noteworthy, leaving open the possibilities of future studies with the adequate nature that allows clarifying the effect of oral hypoglycemic agents in the population with diabetes mellitus and depressive disorder.

Linfadenopatías generalizadas como manifestación inicial de lupus eritematoso sistémico: a propósito de un caso clínico

La presencia de linfadenopatías generalizadas se ha asociado de forma usual con lupus eritematoso sistémico (LES), sin embargo, no es usual encontrar este hallazgo como manifestación inicial de la enfermedad. Existen múltiples diagnósticos diferenciales que incluyen la linfadenitis necrotizante histiocítica de Kikuchi, la enfermedad de Castleman, infecciones y el linfoma cuando se presenta este hallazgo como síntoma inicial de LES. Presentamos el caso de un hombre de 56 años que se presentó con 2 meses de linfadenopatía generalizada sin datos al examen o antecedentes que sugirieran diagnóstico de LES; se sospechó inicialmente linfoma o enfermedad infecciosa y se realizó un estudio exhaustivo incluido biopsia de ganglio cervical. La investigación de laboratorio finalmente reveló leucopenia, proteinuria significativa, ANA y anti-dsDNA positivos e hipocomplementemia, lo que confirma el diagnóstico de enfermedad autoinmune tipo LES. Este caso ilustra la importancia de reconocer esta forma de presentación inusual, dado que se trata de una enfermedad potencialmente fatal.

The presence of generalized lymphadenopathy has usually been associated with systemic lupus erythematosus (SLE), however, it is not usual to find this finding as an initial manifestation of the disease. There are multiple differential diagnoses that include Kikuchi histiocytic necrotizing lymphadenitis, Castleman disease, infections and lymphoma when this finding is presented as an initial symptom of SLE. We present the case of a 56-year-old man who presented with 2 months of generalized lymphadenopathy without examination findings or history suggesting a diagnosis of SLE; Lymphoma or infectious disease was initially suspected and an exhaustive study was performed, including cervical lymph node biopsy. Laboratory investigation finally revealed leukopenia, significant proteinuria, positive ANA, positive anti-dsDNA, and hypocomplementemia, confirming the diagnosis of SLE-type autoimmune disease. This case illustrates the importance of recognizing this unusual presentation, given that it is a potentially fatal disease.

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.

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.

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.

Hemoperfusión con dispositivo CytoSorb en paciente con COVID-19 / Hemoperfusion with the Cytosorb device in a patient with severe COVID-19

Resumen La enfermedad COVID-19 es una enfermedad infecciosa ocasionada por el virus SARS-CoV 2 cuya presentación clínica es muy heterogénea: puede ir desde personas asintomáticas hasta pacientes críticamente enfermos, con tormenta de citoquinas, distrés respiratorio agudo, disfunción de órganos e incluso la muerte. Las terapias actuales para su tratamiento van encaminadas a reducir el impacto de la cascada inflamatoria, y dentro de estas encontramos las tecnologías de hemoadsorción como la membrana CytoSorb. A continuación, presentamos un paciente masculino de 31 años de edad, quien consultó por sintomatología severa de COVID-19 y mostró una evidente mejoría clínica y bioquímica posterior al uso del dispositivo CytoSorb. Este es el único paciente documentado en Colombia al que se le haya realizado terapia de hemoperfusión con este dispositivo en conjunto con terapia de reemplazo renal intermitente prolongada y se hayan registrado desenlaces clínicos favorables.

Abstract The COVID-19 disease is an infectious disease caused by the SARS-CoV 2 virus whose clinical presentation is very heterogeneous: it can range from asymptomatic people to critically ill patients, with cytokine storm, acute respiratory distress, organ dysfunction and even death. Current therapies for its treatment are aimed at reducing the impact of the inflammatory cascade, and within these we find hemoadsorption technologies such as the CytoSorb membrane. Next, we present a 31-year-old male patient, who consulted due to severe symptoms of COVID-19 and showed an evident clinical and biochemical improvement after using the CytoSorb device. This is the only documented patient in Colombia who has undergone haemoperfusion therapy with this device in conjunction with prolonged intermittent renal replacement therapy and favorable clinical outcomes have been recorded.
