Metabolic control in type 2 diabetic patients treated with empagliflozin: A case series. / Control metabólico de pacientes diabéticos tipo 2 tratados con empagliflozina: serie de casos.

Background: Type 2 diabetes mellitus is a highly prevalent disease and is associated with increased morbidity and mortality. Due to the low percentage of adequate glycemic control, new strategies for the treatment of type 2 diabetes mellitus have been sought, including sodium-glucose cotransporter type 2 inhibitorss. Objective: To describe the evolution of patients with type 2 diabetes mellitus with insulin requirements treated with empagliflozin at the Peñaflor Hospital. The primary objective was to evaluate the efficacy of the medication regarding glycosylated hemoglobin A1c (HbA1c). The secondary objectives were: 1) achievement of HbA1c equal to or less than 7.5% according to survival analysis. 2) Change in glomerular filtration rate and urinary albumin excretion post treatment. Methods: Review of clinical records of all patients treated with empagliflozin from November 2019 to June 2023. Average follow-up of 19 (16.3 to 40) months. To compare HbA1c values according to follow-up ranges, the paired T test or Wilcoxon test was used. Results: We included 58 patients, 15 men and 43 women (74.1%), with an average age of 58.5 ± 9.2 years, ranging from 35 to 75 years. Baseline HbA1c of 10.3 ± 1.6% and 8.98% ± 2.2 in a follow-up of 18 to 24 months post-treatment, resulted in a decrease of 1.27% (p = 0.002; confidence interval 95%: 0.5 to 2.03). The most common adverse effect was urinary tract infection. Conclusions: Patients with type 2 diabetes mellitus with insulin requirements treated with empagliflozin at the Peñaflor Hospital achieved better glycemic control with few adverse effects.

Introducción: La diabetes mellitus tipo 2 es una enfermedad de alta prevalencia y está asociada a mayor morbimortalidad. Debido al bajo porcentaje de compensación, se han buscado nuevas estrategias de tratamiento farmacológico, como los inhibidores del cotransportador sodio-glucosa tipo 2. Objetivo: Describir la evolución de pacientes diabéticos tipo 2 insulino-requirentes tratados con empagliflozina en el Hospital Peñaflor, ubicado en el sector poniente de la Región Metropolitana, Chile. El objetivo primario fue evaluar la eficacia del medicamento respecto a hemoglobina glicosilada A1c. Los objetivos secundarios fueron registrar el logro de hemoglobina glicosilada A1c igual o menor a 7,5% según análisis de supervivencia. Luego, consignar el cambio en la velocidad de filtración glomerular y en la excreción urinaria de albúmina post tratamiento. Métodos: Revisión de ficha clínica de todos los pacientes tratados con empagliflozina desde noviembre de 2019 a junio de 2023. Media de seguimiento de 19 (de 16,3 a 40) meses. Para comparación entre valores de hemoglobina glicosilada A1c según rangos de seguimiento, se utilizó prueba T de Student de términos pareados o prueba de Wilcoxon. Resultados: Se estudió a 58 pacientes, 15 hombres y 43 mujeres (74,1%). Edad 58,5 ± 9,2 años, rango de 35 a 75 años. Hemoglobina glicosilada A1c basal de 10,3 ± 1,6% y 8,98% ± 2,2 en un rango de seguimiento de 18 a 24 meses post tratamiento, resultando en un descenso de 1,27% (p = 0,002; intervalo de confianza 95%: 0,5 a 2,03). El efecto adverso más frecuente fue infección del tracto urinario. Conclusiones: Los pacientes diabéticos tipo 2 insulino-requirentes tratados con empagliflozina en el Hospital Peñaflor lograron un mejor control glicémico con pocos efectos adversos.

A clinical mutation in glucokinase causing maturity-onset diabetes in the young type 2 increases enzyme activity.

Glucokinase (GCK) is the pancreatic ß-cell glucose sensor, and its kinetics are key to that purpose. A slow transition step, displayed as non-hyperbolic kinetics, and a low affinity for glucose characterize GCK. Mutations in GCK associated with maturity-onset diabetes of the young type 2 (MODY2) previously described reduce the functionality of the human pancreatic ß-cell, leading to diabetic clinical phenotypes. We present a kinetic characterization of the G448D mutation identified in a MODY2 patient, which is one of the first mutations to exhibit increased functionality. This mutant displays increased activity, high affinity for both Mg2+ -ATP and glucose, hyperbolic kinetics and increased phosphorylation potential. Hyperbolic kinetics and assays in the presence of glycerol indicate that G448D lacks the slow transition step crucial for the pancreatic ß-cell glucose sensor function.

Enfermedades hepáticas y su relación con hiperglicemia / The relationship between liver diseases and hyperglycemia

La Diabetes Mellitus tipo 2 (DM2) y las enfermedades crónicas del hígado(ECH), definida para esta revisión como cualquier alteración funcional o estructural de este órgano, desde inflamación hasta fibrosis, son patologías que frecuentemente se asocian, y su coexistencia se relaciona con peor pronóstico y mayores complicaciones de ambas entidades. El objetivo de este artículo es describir la relación entre hiperglicemia y enfermedades del hígado, sus procesos fisiopatológicos comunes y tratamiento, distinguiendo las patologías más relevantes, entre ellas la Diabetes Hepatogénica (DH), la enfermedad hepática por Virus Hepatitis C (VHC) y la Enfermedad Hepática Grasa No Alcohólica (EHGNA). La DH es aquella diagnosticada en pacientes con cirrosis asociada a insuficiencia hepática, sin antecedentes previos de alteración de la glicemia. En la actualidad el diagnóstico se realiza en etapas tardías de la enfermedad. El VHC tiene un efecto diabetogénico conocido. Algunas terapias antivirales usadas para VHC evidencian mejoría de las alteraciones metabólicas al lograr respuestas virológicas sostenidas. En DM2, la EHGNA es frecuente, con mayor incidencia de fibrosis, hepatocarcinoma (HCC) y riesgo cardiovascular (RCV). Es necesario realizar una pesquisa e intervención precoz de EHGNA a los pacientes con DM2. En el manejo de éstos, la baja de peso ha demostrado ser efectiva en el control glicémico y en la mejoría histológica. Dentro de las terapias antidiabéticas, además del uso de metformina, debería considerarse aquellas que han demostrado a la fecha beneficios en EHGNA, como son tiazolidinedionas (pioglitazona) y/o análogos de GLP-1 (liraglutide) y optimizar el control de otros factores de RCV.

Type 2 Diabetes Mellitus (DM2) and chronic liver diseases (CLD) defined in this revision as any functional or structural alteration in the organ, covering from inflammation to fibrosis, are pathologies that are frequently associated, and when found together are related to worse prognosis and higher complications in both conditions. The objective of this article is to describe the relationship between hyperglycemia and liver diseases, their common physio-pathological processes and treatments, identifying the most important pathologies, including Hepatogenic Diabetes (HD), Hepatitis C Virus (HCV) liver disease and Non-Alcoholic Fatty Liver Disease (NAFLD). Hepatogenic diabetes (HD) is diagnosed in patients with liver failure associated to cirrhosis with no previous record of impaired glycemia. Currently, diagnosis is made during the late stages of the disease. Hepatitis C virus (HCV) has a known diabetogenic effect. Some antiviral therapies used for HCV show improvement in metabolic alterations by achieving sustained virological responses. Non-alcoholic fatty liver disease (NAFLD) in DM2 patients is common, presenting higher risk for fibrosis, hepatocellular carcinoma (HCC) and increased cardiovascular risk (CVR). Early screening and interventions for NAFLD in DM patients are necessary. Weight loss has been shown to be effective in glycemic control and histological improvement. Anti-diabetic therapies, in addition to the use of metformin, should consider therapies that have shown benefits for managing NAFLD, such as thiazolidinedione (pioglitazones) and/or aGLP-1 (Liraglutide), and optimally controlling other cardiovascular risk (CVR) factors.

Conclusion: Degludec in T1D patients showed to reduce fasting glycemia and HbA1c, and lower number of hypoglycemia.

[Second Consensus of the Chilean Society of Endocrinology and Diabetes about insulin resistance]. / II Consenso de la Sociedad Chilena de Endocrinología y Diabetes sobre resistencia a la insulina.

Insulin resistance is a prevalent condition commonly associated with unhealthy lifestyles. It affects several metabolic pathways, increasing risk of abnormalities at different organ levels. Thus, diverse medical specialties should be involved in its diagnosis and treatment. With the purpose of unifying criteria about this condition, a scientific-based consensus was elaborated. A questionnaire including the most important topics such as cardio-metabolic risk, non-alcoholic fatty liver disease and polycystic ovary syndrome, was designed and sent to national experts. When no agreement among them was achieved, the Delphi methodology was applied. The main conclusions reached are that clinical findings are critical for the diagnosis of insulin resistance, not being necessary blood testing. Acquisition of a healthy lifestyle is the most important therapeutic tool. Insulin-sensitizing drugs should be prescribed to individuals at high risk of disease according to clinically validated outcomes. There are specific recommendations for pregnant women, children, adolescents and older people.

Analysis of the intronic single nucleotide polymorphism rs#466452 of the nephrin gene in patients with diabetic nephropathy.

We present the analysis of an intronic polymorphism of the nephrin gene and its relationship to the development of diabetic nephropathy in a study of diabetes type 1 and type 2 patients. The frequency of the single nucleotide polymorphism rs#466452 in the nephrin gene was determined in 231 patients and control subjects. The C/T status of the polymorphism was assessed using restriction enzyme digestions and the nephrin transcript from a kidney biopsy was examined. Association between the polymorphism and clinical parameters was evaluated using multivariate correspondence analysis. A bioinformatics analysis of the single nucleotide polymorphism rs#466452 suggested the appearance of a splicing enhancer sequence in intron 24 of the nephrin gene and a modification of proteins that bind to this sequence. However, no change in the splicing of a nephrin transcript from a renal biopsy was found. No association was found between the polymorphism and diabetes or degree of renal damage in diabetes type 1 or 2 patients. The single nucleotide polymorphism rs#466452 of the nephrin gene seems to be neutral in relation to diabetes and the development of diabetic nephropathy, and does not affect the splicing of a nephrin transcript, in spite of a splicing enhancer site.

[Cystatin C and adiponectin in diabetics with and without coronary artery disease]. / Cistatina C y adiponectina en pacientes diabéticos tipo 2 coronarios y no coronarios.

BACKGROUND: Patients with type 2 diabetes have a high incidence of coronary artery disease, which is even higher among those with renal failure. A serum level of cystatin C are used to assess renal function and is a potential cardiovascular risk factor. Adiponectin is an anti-atherogenic factor. AIM: To measure cystatin C and adiponectin in type 2 diabetic patients with and without coronary artery disease. MATERIAL AND METHODS: Nine diabetic patients with coronary artery disease aged 76+/- 10 years, 20 diabetics without coronary artery disease aged 61 +/-5 years and 20 non diabetic subjects aged 57+/-10 years, were studied. RESULTS: Serum levels of cystatin C (mg/L) were 1.5 (range 0.89-219), 0.81 (range 0.71-1.08) and 0.68 mg/L (range 055-0.75) in diabetics with and without coronary artery disease and controls, respectively (p <0.0001). No differences in adiponectin between groups and no association between cystatin C and adiponectin, were observed. No association between both parameters and body mass index orglycosilated hemoglobin Ale was observed. Cystatin C had a positive correlation with serum creatinine (r =0.57 p <0.001). CONCLUSIONS: Diabetics with coronary artery disease have higher levels of cystatin C, that are closely correlated with serum creatinine levels.

A pilot study on genetic variation in purine-rich elements in the nephrin gene promoter in type 2 diabetic patients.

Diabetic nephropathy (DN) is one of the major complications of type 2 diabetes and is associated with coronary disease. Nephrin, a protein mainly expressed in glomeruli, is decreased in DN and other kidney diseases. Since insulin levels are misregulated in type 2 diabetes, a possible connection between DN and its decreased nephrin expression could be the presence of regulatory elements responsive to insulin in the nephrin gene (NPHS1) promoter region. In this work, using bioinformatic tools, we identified a purine-rich GAGA element in the nephrin gene promoter and conducted a genomic study in search of the presence of polymorphisms in this element and its possible association with DN in type 2 diabetic patients. We amplified and sequenced a 514 bp promoter region of 100 individuals and found no genetic variants in the purine-rich GAGA-box of the nephrin gene promoter between groups of patients with diabetes type 2 with and without renal and coronary complications, control patients without diabetes and healthy controls.

[Asymptomatic bacteriuria in type 2 diabetics women ]. / Bacteriología urinaria asintomática en mujeres diabéticas tipo 2.

BACKGROUND: Urinary tract infection (UTI) is frequent among diabetics, especially women. It may be preceded by asymptomatic bacteriuria. AIM: To study the frequency of asymptomatic bacteriuria in type 2 diabetic women. PATIENTS AND METHODS: Fifty women with type 2 diabetes and 50 non diabetic women were studied. In aseptic conditions, morning midstream urine specimens were obtained for microbiological analysis. The test was repeated in similar conditions during consecutive days. Urine samples were cultured in blood agar, Mac Conkey agar and CPS ID 2. Colony forming units were counted. Asymptomatic bacteriuria was defined as the presence of 100,000 or more colony forming units per ml. Leukocyturia was also quantified. RESULTS: There was microbial growth in 40% of samples from diabetic women and 6% of samples from controls (p < 0.01). Asymptomatic bacteriuria was present in 32% of diabetics and 4% of controls (p < 0.01). E Coli was the most frequently isolated strain, in 55% of patients and 100% of controls. Klebsiella pneumoniae was isolated in 10% of diabetics, coagulase negative Staphylococcus in 10%, Enterococcus spp in 10% and Pseudomonas aeruginosa in 5%. Leukocyturia of more than 10 cells per field, was present in 80% of diabetic women with positive culture. Women with positive cultures had a longer lasting diabetes than those with negative cultures. There was no association between urine microbiological results and glycosilated hemoglobin, fasting blood glucose, chronic complications of diabetes and treatment received. CONCLUSIONS: This study shows a high prevalence of asymptomatic bacteriuria among diabetic women.

Terapia nutricional en el control de las dislipidemias / Nutritional therapy in dyslipidemia control

Se estudió la eficacia de la terapia nutricional exclusiva sobre el perfil lipídico en pacientes dislipidémicos. A 43 individuos con dislipidemia mixta y a 29 con hipercolesterolemia aislada, se les indicó la fase 2 de la recomendación del National Cholesterol Education Program: 30 por ciento de las calorías como lípidos (<75 por ciento como grasas saturadas, 10 por ciento de poliinsaturadas y 13 por ciento de monoinsaturadas); ingesta de colesterol (200 mg/día). Al control (2 a 4 meses) se observó una disminución significativa del colesterol y triglicéridos; en un 20 por ciento se logró la normalización de estos parámetros. El 25 por ciento de los pacientes aumentó el colesterol y los triglicéridos (NS). Tanto los hombres como las mujeres con HDL en cifras de riesgo elevaron sus niveles (p < 0.01); las LDL disminuyeron significativamente en los hombres con dislipidemia mixta y en las mujeres con hipercolesterolemia aislada. Las tasas de riesgo colesterol/HDL y LDL/HDL no se modificaron. En un 35 por ciento de los sujetos los menores niveles de colesterol se asociaron a una reducción de las HDL, pero sin alcanzar tasas de riesgo. La dieta disminuyó la correlación negativa entre triglicéridos y HDL que presentaban los pacientes al ingreso. La terapia nutricional exclusiva es efectiva en modificar el perfil lipídico de los dislipidémicos; sin embargo, es necesario agregar otras medidas no farmacológicas (ejercicio, supresión del tabaco) y farmacológicos para obtener una real disminución de las tasas de riesgo cardiovascular

Prevalencia de hipertensión arterial y nefropatía en pacientes con diabetes mellitus no insulinodependientes / Prevalence of arterial hypertension and nephropathy in patients with non-insulindependent diabetes mellitus

La prevalencia de hipertensión arterial en la población de pacientes diabéticos estudiada fue de 53,6 por ciento , superior a la encontrada en otros estudios, sin diferencias de sexo. La edad promedio de diagnóstico de hipertensión arterial en esta población es de 57 años, siendo, en promedio 6 años posterior al diagnóstico de la DMNID. La frecuencia de hipertensión arterial se mantiene constante en 50 por ciento hasta los 20 años de evolución de la DMNID con un aumento posterior a mayor de edad. La prevalencia de hipertensión arterial aumenta cuando hay mal control metabólico ee IMC más altos. Las prevalencia de nefropatía en lapoblación de pacientes diabéticos fue de 14,4 por ciento . No se encontró asociación entre control metabólico y nefropatía, ni entre esta última e hipertensión arterial

El clamp glicémico: método para evaluar la sensibilidad tisular a la insulina / Glycemic clamp: a method to assess tissue sensitivity to insulin

La medición de la sensibilidad tisular a la insulina, requiere de un valor cuantitativo que relacione la concentración plasmática de la hormona con algún proceso metabólico dependiente de la insulina cuantificable. Se han desarrollado diversos sistemas para la determinación de los efectos in vivo inducidos por cambios conocidos en los niveles de insulina plasmática, siendo uno de ellos el clamp glicémico-insulínico. Esta técnica es una aplicación del principio de retroalimentación negativa al sistema que regula la concentración plasmática de glucosa, y se basa en mantener una glicemia constante mediante administración endovenosa continua de glucosa según las necesidades, mientras se perfunde insulina a dosis fijas. La tasa de infusión de glucosa es la medida más exacta de la sensibilidad a la insulina y en el estado estable, es equivalente al promedio de la tasa de captación de glucosa, corrigiendo las pérdidas urinarias. Los clamps de glucosa han encontrado una gran aplicación práctica, en estudios que tienden a determinar la acción antidiabética de las drogas hipoglicemiantes orales sobre la función beta-celular y la sensibilidad a la insulina
