The athero-contour: A novel tool for global and rapid assessment of atherogenic parameters. A use case in saroglitazar treatment of MAFLD patients.

BACKGROUND AND AIMS: Comprehensive assessment of pharmacotherapy effects on atherogenic parameters (AP) that influence the risk of cardiovascular disease (CVD) is challenging due to interactions among a large number of parameters that modulate CVD risk. METHODS: We developed an illustrative tool, athero-contour (AC), which incorporates weighted key lipid, lipo- and glycoprotein parameters, to readily illustrate their overall changes following pharmacotherapy. We demonstrate the applicability of AC to assess changes in AP in response to saroglitazar treatment in patients with metabolic associated fatty liver disease (MAFLD) in the EVIDENCES IV study. RESULTS: The baseline AC of saroglitazar and placebo groups was worse than the mean of the general population. After 16-week treatment, AC improved significantly in the saroglitazar group due to alterations in very low-density lipoprotein, triglyceride, and glycoproteins. CONCLUSION: Using AC, we could readily and globally evaluate and visualize changes in AP. AC improved in patients with MAFLD following saroglitazar therapy.

Targeting metabolic-associated fatty liver disease in diabetic kidney disease: A call to action.

Nonalcoholic fatty liver disease or metabolic-associated fatty liver disease (MAFLD) is a common condicion with increasing prevalence and incidence, specially in patients with type 2 diabetes mellitus (T2DM). Both cardiovascular and renal disease are clearly increased in these patients, particularly in those with diabetic nephropathy. In the liver-heart-kidney-metabolic axis, the common pathophysiological basis of MAFLD, cardiovascular disease (CVD), chronic kidney disease (CKD), and T2DM is the same. The clinical relationship between all of them is clear and is multidirectional: MAFLD may precede the development of cardiovascular and renal disease, and may also worsen the prognosis of these complications once developed. In this review we emphasize the importance of targeting MAFLD in Diabetic kidney disease, with the goal of detecting high-risk patients in order to improve their prognosis.

Esteatosis hepática metabólica y nefropatía diabética: una llamada a la acción / Targeting metabolic-associated fatty liver disease in diabetic kidney disease: A call to action

La incidencia y la prevalencia de hígado graso no alcohólico o enfermedad hepática metabólica (EHmet) está en aumento y es mayor en pacientes con diabetes mellitus tipo 2 (DM2). El riesgo cardiovascular y renal está claramente incrementado en estos pacientes, especialmente cuando se desarrolla nefropatía diabética. El eje cardio-reno-hepato-metabólico, conformado por la enfermedad cardiovascular (ECV), la enfermedad renal crónica (ERC), la EHmet y la DM2, tiene una base fisiopatogénica común. La relación clínica entre todos los componentes es inevitable y multidireccional, pudiendo la EHmet preceder al desarrollo de complicaciones cardiovasculares y renales, y también empeorar el pronóstico de las mismas una vez desarrolladas. En esta revisión enfatizamos la importancia de buscar y tratar la EHmet en pacientes con ERC y DM2 con el objetivo de identificar pacientes de mayor riesgo y de mejorar su pronóstico.(AU)

NAFLD and type 2 diabetes: A practical guide for the joint management / Esteatosis hepática metabólica y diabetes mellitus tipo 2: Una guía práctica para el manejo conjunto

Non-alcoholic fatty liver disease (NAFLD) is becoming a major cause of liver disease-related morbidity, as well as mortality. Importantly, NAFLD is considered a mediator of systemic diseases including cardiovascular disease. Its prevalence is expected to increase, mainly due to its close association with obesity and type 2 diabetes mellitus (T2D). In addition, T2D and NAFLD share common pathophysiological mechanisms, and one can lead to or worsen the other. Therefore, a close collaboration between primary care physician, endocrinologists and hepatologists is essential to optimize the management of patients with NAFLD and T2D. Here, we summarize relevant aspects about NAFLD and T2D that all clinician managing these patients should know as well as current therapeutic options for the treatment of T2D associated with NAFLD. (AU)

La esteatosis hepática metabólica (EHmet) se está convirtiendo en una de las causas más importantes de morbimortalidad relacionada con las enfermedades hepáticas. Es importante destacar que la EHmet se considera un mediador de enfermedades sistémicas, incluidas las enfermedades cardiovasculares. Se espera que su prevalencia aumente, principalmente debido a su estrecha relación con la obesidad y la diabetes mellitus tipo 2 (DM2). Además, la DM2 y la EHmet comparten mecanismos fisiopatológicos comunes y una puede provocar o empeorar la otra. Por lo tanto, una estrecha colaboración entre el médico de atención primaria, endocrinólogos y hepatólogos es fundamental para optimizar el manejo de los pacientes con EHmet y DM2. En esta guía resumimos aspectos relevantes sobre EHmet y DM2 que todo médico que maneja a estos pacientes debe conocer, así como las opciones terapéuticas actuales para el tratamiento de DM2 asociada a EHmet.

Prediction of clinical events by liver stiffness and chronic kidney disease by NAFLD in patients with type-2 diabetes / Predicción de eventos clínicos por elasticidad hepática y enfermedad renal crónica por EHMet en pacientes con diabetes tipo 2

Background & Aims: Non-alcoholic fatty liver disease (NAFLD) is associated with poorer glycemic control and a higher risk of type-2 diabetes (T2D) complications, extrahepatic and cardiovascular disease (CVD). Our study aim was to evaluate the association between NAFLD, T2D complications, and the development of overall clinical events (OCE) (CV, liver-related, and mortality) in patients with T2D. Methods: Prospective single-center study comprising T2D subjects with no history of CVD and non-T2D matched controls. Patients were selected from the Outpatient Diabetes Clinic of Vall d’Hebron Hospital and related primary care centers. Results: 186 diabetics and 57 controls were included. Amongst T2D, 124/186 subjects had NAFLD (66.6%). T2D-NAFLD subjects showed a heavier metabolic burden and higher median liver stiffness (5.6kPa [4.5–7.3] vs 4.8 [4.2–5.8]; p=0.004) compared to non-NAFLD diabetics. During a median follow-up of 5.6 years, 33 (17.7%) T2D patients developed OCE vs 4 (7.0%) controls (p=0.049). No differences were found for OCE between NAFLD and non-NAFLD diabetics (16.9% vs 19.4%; p=0.68). CV was the most reported outcome and only one liver event occurred. NAFLD diabetics showed more often chronic kidney disease (CKD), whereas T2D complications and subclinical CVD rates were similar. A higher liver stiffness, older age, and male gender were independently associated with OCE amongst the entire T2D population and NAFLD diabetics. Conclusions: NAFLD and liver stiffness were associated with CKD and clinical outcomes in diabetics, respectively. A hepatic evaluation is recommended to identify high-risk T2D patients that would benefit from early referral to specialized care. (AU)

Antecedentes y objetivos: La esteatosis hepática metabólica (EHMet) se asocia con un peor control glucémico y un mayor riesgo de complicaciones de la diabetes tipo 2 (DM2), enfermedad extrahepática y cardiovascular (CV). El objetivo fue evaluar la asociación entre EHMet, complicaciones microvasculares y el desarrollo de eventos clínicos globales (ECG) (CV, hepáticos y mortalidad) en diabéticos. Métodos: Estudio unicéntrico prospectivo que incluye diabéticos sin historia de CV y controles sin DM2. Se seleccionaron pacientes de la consulta de Diabetes del Hospital Vall d’Hebron y centros de atención primaria asociados. Resultados: Se incluyeron 186 diabéticos y 57 controles. Entre los diabéticos, 124/186 presentaron EHMet (66,6%). Los pacientes DM2 con EHMet presentaron mayor carga metabólica y una elasticidad hepática superior (5,6kPa [4,5-7,3] vs. 4,8 [4,2-5,8]; p=0,004) a los diabéticos sin EHMet. Durante una mediana de seguimiento de 5,6 años, 33 (17,7%) diabéticos desarrollaron ECG vs. 4 (7,0%) controles (p=0,049). No hubo diferencias en ECG entre diabéticos con y sin EHMet (16,9% vs. 19,4%; p=0,68). El evento más reportado fue CV y solamente se produjo un evento hepático. La enfermedad renal crónica (ERC) fue más frecuente en diabéticos con EHMet, mientras que los ratios de complicaciones microvasculares y enfermedad CV silente fueron similares. El género masculino, una mayor edad y elasticidad hepática se asociaron de forma independiente a ECG para el total de diabéticos y para aquellos con EHMet. Conclusiones: La EHMet y la elasticidad hepática se asociaron a ERC y eventos clínicos en diabéticos. Se recomienda una evaluación hepática para identificar pacientes diabéticos de riesgo que se beneficiarían de una derivación precoz al especialista. (AU)

Prevalencia de esteatosis hepática no alcohólica en una ciudad española: estudio poblacional / Prevalence of nonalcoholic fatty liver disease in a Spanish town: A population-based study

Objetivo La esteatosis hepática no alcohólica (EHNA) es la causa más importante de esteatosis hepática e hipertransaminasemia en los países occidentales. El objetivo consistía en determinar la prevalencia de EHNA entre 261025 personas del área de salud pública de Valladolid Este en España. Métodos Se seleccionó al azar a 1800 participantes a partir de una base de datos de tarjetas del sistema sanitario público, que fueron representativos de la mayor parte de la población. En todos los pacientes se realizó una historia clínica, medición de parámetros antropométricos, ecografía abdominal y análisis de sangre para descartar hepatopatía. También se calculó la puntuación FLI en todos los casos. Resultados Cuatrocientos cuarenta y ocho participantes aceptaron participar en el estudio. La prevalencia de EHNA en nuestro estudio fue del 22,3% (18,5-26,2%). La prevalencia fue máxima entre los 50 y los 70 años, y se incrementó con la edad (p <0,006). No hubo diferencias significativas en cuanto al sexo (p=0,338). La mediana del índice de masa corporal fue de 27,2 y la EHNA se relacionó con el peso (p <0,001) y el perímetro abdominal (p <0,001). El análisis de regresión logística reveló que una γ-GT inferior a 26 UI/ml, un índice de masa corporal superior a 31 y una puntuación HOMA-IR superior a 2,54 fueron factores predictivos independientes de EHNA en la muestra. El diagnóstico de EHNA se correspondió con una puntuación FLI elevada en el 88% de los casos. Conclusiones De acuerdo con otros estudios epidemiológicos, la prevalencia de EHNA es muy alta. Un estudio completo con consulta clínica, estudios de imagen y análisis de sangre en todos los pacientes permite determinar la prevalencia de EHNA en la población (AU)

Objective Nonalcoholic fatty liver disease (NAFLD) is western countries’ most important cause of hepatic steatosis and hypertransaminasemia. The objective was to evaluate the prevalence of NAFLD among 261,025 people in the East Valladolid public healthcare area in Spain. Methods We randomly selected 1800 participants from a public healthcare system card database, representing most of the population. We performed a medical record, measurement of anthropometric parameters, abdominal ultrasound, and blood tests to rule out hepatic disease in all patients. We calculated the FLI score in all patients. Results Four hundred and forty-eight participants agreed to participate in the study. The prevalence of nonalcoholic fatty liver disease in our study was 22.3% [18.5–26.2%]. Prevalence was highest between 50 and 70 years, increasing with age (p < 0.006). There were no significant differences in sex (p = 0.338). The median body mass index was 27.2, and NAFLD was related to the weight (p < 0.001) and abdominal perimeter (p < 0.001). Logistic regression analysis showed GGT lower than 26UI/ml, body mass index higher than 31, and HOMA IR greater than 2.54 as independent factors to predict NAFLD in the sample. NAFLD diagnosis matched with an elevated FLI score in 88% of cases. Conclusion According to other epidemiological studies, NAFLD's prevalence is very high. A complete study with a clinical consultation, image studies, and blood tests in all patients allows us to assess the prevalence of NAFLD in the population (AU)

Prevalence of metabolic associated fatty liver disease (MAFLD) in patients with gallstone disease. Study on a cohort of cases in South-Southeastern Mexico.

INTRODUCTION: Metabolic (dysfunction) associated fatty liver disease (MAFLD) and gallstone disease are entities that share similar risk factors. Numerous publications confirm their elevated frequency, but few studies have considered their prevalence and possible association. AIMS: To determine the prevalence of MAFLD in patients with gallstone disease and the usefulness of liver biopsy for diagnosing the liver disease. MATERIALS AND METHODS: A prospective study was conducted on patients that underwent laparoscopic cholecystectomy, in whom liver biopsy was performed. VARIABLES ANALYZED: Anthropometric characteristics, biochemical profile, conventional ultrasound, risk factors, and histopathologic study of the liver biopsy. STATISTICAL ANALYSIS: Descriptive statistics were carried out for the quantitative variables and the Student's t test and multivariate analysis through binary logistic regression were employed for the continuous variables, utilizing IBM-SPSS, 25.0 (Windows) software. RESULTS: A total of 136 patients were classified into 2 groups: 40 (29.41%) with normal liver and 96 (70.59%) with MAFLD. Of the 136 patients, 71 patients (52.21%) corresponded to hepatic steatosis, 21 (15.44%) to steatohepatitis, and 4 (2.94%) to cirrhosis. Perisinusoidal inflammation was found in 39 cases (28.68%) and fibrosis was found in 10 (7.35%). The risk factors for both groups were age, diabetes, high blood pressure, and obesity. Glucose, triglyceride, and aminotransferase levels were significantly higher in the MAFLD group and conventional ultrasound demonstrated moderate concordance for its detection. DISCUSSION AND CONCLUSIONS: The results confirmed the elevated frequency of MAFLD associated with gallstone disease, justifying liver biopsy during cholecystectomy for diagnosing MAFLD.

Abordaje común del paciente con psoriasis y riesgo de esteatosis hepática metabólica: recomendaciones de un grupo de expertos multidisciplinar / Common Approach to Metabolic-Associated Fatty Liver Disease in Patients With Psoriasis: Consensus-Based Recommendations From a Multidisciplinary Group of Experts

En los últimos años se están haciendo notables esfuerzos para entender la relación existente entre la psoriasis y la esteatosis hepática metabólica (EHmet). No solo se presenta este trastorno en pacientes psoriásicos con una mayor prevalencia, sino que además se acompaña de una mayor gravedad. Con este precedente, se evidencia la necesidad de establecer un protocolo de abordaje precoz de la enfermedad hepática en los pacientes con psoriasis. Asimismo, es de especial relevancia la evaluación de riesgo y beneficio en referencia al uso de tratamientos con potencial hepatotóxico. En el presente manuscrito se exponen las recomendaciones de un panel de expertos en dermatología y hepatología para el cribado, diagnóstico, monitorización y criterios de derivación en pacientes con psoriasis, en caso de sospecha de esteatosis hepática metabólica (AU)

Recent years have seen concerted efforts to understand the relation between psoriasis and metabolic-associated fatty liver disease (MAFLD). Not only is MALFD diagnosed more often in patients with psoriasis, but its clinical course is also more aggressive. A common approach is therefore needed to enable early detection of liver disease coincident with psoriasis. Especially important is an analysis of risks and benefits of potentially hepatotoxic treatments. This consensus paper presents the recommendations of a group of experts in dermatology and hepatology regarding screening for MALFD as well as criteria for monitoring patients and referring them to hepatologists when liver disease is suspected (AU)

NAFLD and type 2 diabetes: A practical guide for the joint management.

Non-alcoholic fatty liver disease (NAFLD) is becoming a major cause of liver disease-related morbidity, as well as mortality. Importantly, NAFLD is considered a mediator of systemic diseases including cardiovascular disease. Its prevalence is expected to increase, mainly due to its close association with obesity and type 2 diabetes mellitus (T2D). In addition, T2D and NAFLD share common pathophysiological mechanisms, and one can lead to or worsen the other. Therefore, a close collaboration between primary care physician, endocrinologists and hepatologists is essential to optimize the management of patients with NAFLD and T2D. Here, we summarize relevant aspects about NAFLD and T2D that all clinician managing these patients should know as well as current therapeutic options for the treatment of T2D associated with NAFLD.

Prediction of clinical events by liver stiffness and chronic kidney disease by NAFLD in patients with type-2 diabetes.

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is associated with poorer glycemic control and a higher risk of type-2 diabetes (T2D) complications, extrahepatic and cardiovascular disease (CVD). Our study aim was to evaluate the association between NAFLD, T2D complications, and the development of overall clinical events (OCE) (CV, liver-related, and mortality) in patients with T2D. METHODS: Prospective single-center study comprising T2D subjects with no history of CVD and non-T2D matched controls. Patients were selected from the Outpatient Diabetes Clinic of Vall d'Hebron Hospital and related primary care centers. RESULTS: 186 diabetics and 57 controls were included. Amongst T2D, 124/186 subjects had NAFLD (66.6%). T2D-NAFLD subjects showed a heavier metabolic burden and higher median liver stiffness (5.6kPa [4.5-7.3] vs 4.8 [4.2-5.8]; p=0.004) compared to non-NAFLD diabetics.

Changes in indications for outpatient percutaneous liver biopsy over 5 years: from hepatitis C to fatty liver disease / Cambios en las indicaciones de la biopsia hepática percutánea ambulatoria durante 5 años: de hepatitis C a enfermedad del hígado graso

Introduction: Although the use of non-invasive methods for assessment of liver fibrosis has reduced the need for biopsy, the diagnosis of liver damage still requires histological evaluation in many patients. We aim to describe the indications for percutaneous liver biopsy (PLB) and the rate of complications in an outpatient setting over 5 years. Methods: This observational, single-center, and retrospective study included patients submitted to real-time ultrasound (US)-guided biopsies from 2015 to 2019. We collected age, gender, coagulation tests, comorbidities, and the number of needle passes. The association between the variables and complications was evaluated using the generalized estimating equations method. Results: We analyzed 532 biopsies in 524 patients (55.3% male) with a median age of 49 years (range 13–74y). An average of 130.3 biopsies per year were performed in the first 3 years of the study versus 70.5 in the other 2y. The main indications were hepatitis C virus (HCV) infection (47.0%), autoimmune and cholestatic liver diseases (12.6%), and metabolic dysfunction-associated fatty liver disease (MAFLD) (12.1%). The number of HCV-related biopsies had a remarkable reduction, while MAFLD-related procedures have progressively raised over time. Around 54% of the patients reported pain, which was significantly associated with females (p=0.0143). Serious complications occurred in 11 patients (2.1%) and hospital admission was necessary in 10 cases (1.9%). No patient required surgical approach and there were no deaths. No significant association was found between the studied variables and biopsy-related complications. Conclusion: The indications for PLB in an outpatient setting have changed from HCV to MAFLD over the years. This procedure is safe and has a low rate of serious complications, but new strategies to prevent the pain are still needed, especially for females.(AU)

Introducción: Aunque el uso de métodos no invasivos para evaluar la fibrosis hepática ha reducido la necesidad de una biopsia, el diagnóstico de daño hepático aún requiere una evaluación histológica en muchos pacientes. Nuestro objetivo es describir las indicaciones de la biopsia hepática percutánea ambulatoria y la tasa de complicaciones durante cinco años. Métodos: Este estudio observacional, retrospectivo y unicéntrico incluyó pacientes sometidos a biopsias guiadas por ecografía en tiempo real desde 2015 hasta 2019. Recogimos información sobre edad, sexo, pruebas de coagulación, comorbilidades y número de pasadas de aguja. La asociación entre variables y complicaciones se evaluó mediante el método de ecuaciones de estimación generalizada. Resultados: Analizamos 532 biopsias en 524 pacientes (55,3% hombres) con una edad media de 49 años (rango de 13 a 74 años). Se realizó una media de 130,3 biopsias por año en los primeros tres años del estudio frente a 70,5 en los otros dos años. Las principales indicaciones fueron la infección por el virus de la hepatitis C (HCV) (47,0%), las enfermedades hepáticas autoinmunes y colestásicas (12,6%) y la enfermedad del hígado graso asociada a disfunción metabólica (MAFLD) (12,1%). El número de biopsias relacionadas con la HCV tuvo una reducción notable, mientras que los procedimientos relacionados con MAFLD han aumentado progresivamente con el tiempo. Alrededor del 54% de los pacientes informaron dolor, que se asoció significativamente con las mujeres (p = 0,0143). Se produjeron complicaciones graves en 11 pacientes (2,1%) y el ingreso hospitalario fue necesario en 10 casos (1,9%). Ningún paciente requirió abordaje quirúrgico y no hubo muertes. No se encontró asociación significativa entre las variables estudiadas y las complicaciones relacionadas con la biopsia. Conclusión: Las indicaciones para la biopsia hepática percutánea ambulatoria han cambiado de HCV a MAFLD con el pasar de los años.(AU)

Prevalence of non-alcoholic fatty liver disease (NAFLD) in a cohort of patients with type 2 diabetes: the PHIGNA-DM2 study.

Introduction: Background: type 2 diabetes (T2D) is a risk factor for nonalcoholic fatty liver disease (NAFLD). Objective: to evaluate the prevalence of NAFLD in a cohort of patients with T2D. Methods: an observational, descriptive study performed between May 2018 and December 2019 at the Endocrinology and Nutrition Unit. The χ² test was performed for qualitative variables and a non-parametric test for the comparison of medians of quantitative variables. Steatosis degree was defined by the coefficient attenuated parameter (CAP): (S0: < 248 dB/m; S1: 248-268 dB/m; S2: 268-288 dB/m; S3: > 288 dB/m) or stiffness: F0-F1: < 8 kPa; F2: 8-10 kPa; F3: 10-15 kPa; F4: > 15 kPa, using transient elastography (TE) (FibroScan®). A univariate analysis was performed and subsequently a multivariate analysis with statistically significant variables used to study the predictive factors of intense steatosis and advanced fibrosis. Results: n = 104 patients with T2D; 84 (80.7 %) were obese. TE demonstrated advanced fibrosis in 20 % and intense steatosis (S3) in more than 50 %. Lower total bilirubin (OR: 0.028; 95 % CI: (0.002-0.337); p = 0.005) was found to be an independent factor for S3 steatosis in the multivariate analysis. BMI ((OR: 1.497; 95 % CI: (1.102-2.034); p = 0.01)) was a predictive factor for advanced fibrosis in a multivariate analysis. Conclusions: NAFLD-associated intense steatosis and NAFLD-associated fibrosis were commonly found in patients with T2DM and obesity. Diabetic patients should be screened for liver disease as one more target organ.

Introducción: Antecedentes: la diabetes de tipo 2 (DM2) es un factor de riesgo para la enfermedad del hígado graso no alcohólico (EHGNA). Objetivo: evaluar la prevalencia de la EHGNA en una cohorte de pacientes con DM2. Métodos: estudio descriptivo observacional realizado entre mayo de 2018 y diciembre de 2019 en la Unidad de Endocrinología y Nutrición. Se realizó una prueba de χ² para las variables cualitativas y una prueba no paramétrica para la comparación de medianas de variables cuantitativas. El grado de esteatosis se definió mediante el parámetro coeficiente atenuado (CAP): (S0: < 248 dB/m; S1: 248-288 dB/m; S2: 268-288 dB/m; S3: > 288 dB/m) o rigidez: F0-F1: < 8 kPa; F2: 8-10 kPa; F3: 10-15 kPa; F4: > 15 kPa, usando la elastografía transitoria (TE) (FibroScan®). Se realizó un análisis univariante y posteriormente un análisis multivariante con las variables estadísticamente significativas para estudiar los factores predictivos de esteatosis intensa y fibrosis avanzada. Resultados: n = 104 pacientes con DM2; 84 (80,7 %) eran obesos. La TE demostró fibrosis avanzada en el 20 % y esteatosis intensa (S3) en más del 50 %. Los niveles disminuidos de bilirrubina total (OR: 0.028; 95 % CI: (0.002-0.337); p = 0.005) se encontraron como factores independientes para la esteatosis S3 en el analisis multivariable. El IMC (OR: 1.497; 95 % CI: (1.102-2.034); p = 0.01) fue un factor predictivo de fibrosis avanzada. Conclusiones: la esteatosis intensa asociada a EHGNA y la fibrosis asociada a EHGNA se encontraron comúnmente en pacientes con DM2 y obesidad.

Background: type 2 diabetes (T2D) is a risk factor for nonalcoholic fatty liver disease (NAFLD). Objective: to evaluate the prevalence of NAFLD in a cohort of patients with T2D. Methods: an observational, descriptive study performed between May 2018 and December 2019 at the Endocrinology and Nutrition Unit. The χ² test was performed for qualitative variables and a non-parametric test for the comparison of medians of quantitative variables. Steatosis degree was defined by the coefficient attenuated parameter (CAP): (S0: < 248 dB/m; S1: 248-268 dB/m; S2: 268-288 dB/m; S3: > 288 dB/m) or stiffness: F0-F1: < 8 kPa; F2: 8-10 kPa; F3: 10-15 kPa; F4: > 15 kPa, using transient elastography (TE) (FibroScan®). A univariate analysis was performed and subsequently a multivariate analysis with statistically significant variables used to study the predictive factors of intense steatosis and advanced fibrosis. Results: n = 104 patients with T2D; 84 (80.7 %) were obese. TE demonstrated advanced fibrosis in 20 % and intense steatosis (S3) in more than 50 %. Lower total bilirubin (OR: 0.028; 95 % CI: [0.002-0.337]; p = 0.005) was found to be an independent factor for S3 steatosis in the multivariate analysis. BMI (OR: 1.497; 95 % CI: [1.102-2.034]; p = 0.01) was a predictive factor for advanced fibrosis in a multivariate analysis. Conclusions: NAFLD-associated intense steatosis and NAFLD-associated fibrosis were commonly found in patients with T2DM and obesity. Diabetic patients should be screened for liver disease as one more target organ. (AU)

Antecedentes: la diabetes de tipo 2 (DM2) es un factor de riesgo para la enfermedad del hígado graso no alcohólico (EHGNA). Objetivo: evaluar la prevalencia de la EHGNA en una cohorte de pacientes con DM2. Métodos: estudio descriptivo observacional realizado entre mayo de 2018 y diciembre de 2019 en la Unidad de Endocrinología y Nutrición. Se realizó una prueba de χ² para las variables cualitativas y una prueba no paramétrica para la comparación de medianas de variables cuantitativas. El grado de esteatosis se definió mediante el parámetro coeficiente atenuado (CAP): (S0: < 248 dB/m; S1: 248-288 dB/m; S2: 268-288 dB/m; S3: > 288 dB/m) o rigidez: F0-F1: < 8 kPa; F2: 8-10 kPa; F3: 10-15 kPa; F4: > 15 kPa, usando la elastografía transitoria (TE) (FibroScan®). Se realizó un análisis univariante y posteriormente un análisis multivariante con las variables estadísticamente significativas para estudiar los factores predictivos de esteatosis intensa y fibrosis avanzada. Resultados: n = 104 pacientes con DM2; 84 (80,7 %) eran obesos. La TE demostró fibrosis avanzada en el 20 % y esteatosis intensa (S3) en más del 50 %. Los niveles disminuidos de bilirrubina total (OR: 0.028; 95 % CI: (0.002-0.337); p = 0.005) se encontraron como factores independientes para la esteatosis S3 en el analisis multivariable. El IMC (OR: 1.497; 95 % CI: (1.102-2.034); p = 0.01) fue un factor predictivo de fibrosis avanzada. Conclusiones: la esteatosis intensa asociada a EHGNA y la fibrosis asociada a EHGNA se encontraron comúnmente en pacientes con DM2 y obesidad. Los pacientes diabéticos deben someterse a pruebas de detección de enfermedad hepática como un órgano diana más. (AU)

Resultados: el sexo predominante en la tensión arterial sistólica fue el femenino con un 44.9 % en estadio prehipertensión, mientras que el masculino fue el sexo predominante en presión arterial diastólica con un 49.1 %. Se evidenció que los individuos con IMC del percentil 90 se encontraban en estadio prehipertensión en el percentil. El perfil lipídico (colesterol, HDL, LDL, triglicéridos) y las transaminasas (SGOT y SGPT) mostraron relación con niveles tensionales elevados con predominio en la TAD. Los valores elevados de glicemia presentan relación con las cifras aumentadas de la tensión arterial sistólica. Conclusión: el estudio mostró que existe una relación entre la esteatosis hepática no alcohólica y el riesgo de desarrollar hipertensión arterial. Presentando relación estadísticamente significativa entre los niveles tensionales elevados y el perfil bioquímico estudiado, así como al IMC de los pacientes evaluados en la investigación

Introduction: Nonalcoholic fatty liver disease (NAFLD) is a multifactorial disorder whose risks factors can be attributed to obesity, sedentary lifestyle and a genetic component. Objective: To evaluate blood pressure levels in children and adolescent aged 5-18 years old with hepatic steatosis using ultrasound at the Dr. Arturo Grullón Regional University Hospital. Methods and Techniques: A descriptive cross-sectional study of primary source were carried out. The sample of the study consisted in 106 participants. Abdominal ultrasono-graphy was performed to determine the presence of hepatic steatosis and systolic and diastolic blood pressure, BMI, height and laboratory tests were measured. Chi square was used in the statistical analysis of the data. Results: The predominant sex in systolic blood pressure was female with 44.9% in prehypertension stage, while male was the predominant sex in diastolic blood pressure with 49.1%. It was evidenced that individuals with BMI ≥90thpercentile were in the prehypertensive stage at the percentile. The lipid profile (cholesterol, HDL-C, LDL-C, triglycerides) and transaminases (SGOT ad SGPT) showed a relationship with high blood pressure levels with a predo-minance in DBP. Elevated glucose levels are related to an increase in systolic blood pressure. Conclusion: The study showed that there is a relationship between nonalcoholic fatty liver disease and the risk of developing high blood pressure. Presenting a statistically significant relationship between the elevated blood pres-sure levels and the biochemical profile studied, as well the BMI of the patients evaluated in this research

El ácido bempedoico como activador PPAR alfa: Nuevas perspectivas para el tratamiento de la esteatosis hepática en un modelo experimental de rata hembra / Bempedoic acid as a PPAR alfa activator: new perspectives for hepatic steatosis treatment in a female rat experimental model

INTRODUCCIÓN: La enfermedad del hígado graso no alcohólico cursa, en sus fases iniciales, con hipertrigliceridemia y acúmulo de lípidos en el hígado (esteatosis hepática). El ácido bempedoico es un inhibidor de la ATP:citrato liasa que promueve una inhibición dual de la síntesis de colesterol y ácidos grasos. Sin embargo, no se ha investigado su efecto en la prevención/tratamiento de la esteatosis hepática y la hipertrigliceridemia. El objetivo de nuestro trabajo ha sido elucidar si el ácido bempedoico, mediante un mecanismo diferente/alternativo a la inhibición de la ATP:citrato liasa, revierte estas alteraciones metabólicas. DISEÑO EXPERIMENTAL: El estudio se realizó con un modelo animal de rata Sprague-Dawley hembra alimentada, durante 3 meses, con una dieta rica en grasa saturada suplementada con fructosa al 10% (p/v) en el agua de bebida. Se administró, durante el último mes, ácido bempedoico (30mg/kg/día) a un grupo de animales. Se analizaron parámetros zoométricos, se realizaron valoraciones plasmáticas, de expresión génica y proteica en muestras de hígado y se determinó la actividad de unión PPAR-PPRE. RESULTADOS: Nuestro modelo de intervención dietética desarrolló esteatosis hepática e hipertrigliceridemia. A pesar de un aumento en la ingesta calórica total, no se observó un incremento de peso corporal de los animales. La administración de ácido bempedoico redujo significativamente la esteatosis hepática y promovió una marcada hipertrofia de los hepatocitos. Se observó un incremento del 66% en el peso del hígado de los animales tratados con el fármaco, que no se acompañó de modificaciones en los marcadores de inflamación, estrés oxidativo o estrés de retículo endoplasmático. El ácido bempedoico activó el receptor nuclear activado por proliferadores peroxisómicos (PPARα) y sus genes diana.

INTRODUCTION: In its initial stages, nonalcoholic fatty liver disease presents hypertriglyceridemia and accumulation of lipids in the liver (hepatic steatosis). Bempedoic acid is an ATP:citrate lyase inhibitor that promotes a dual inhibition of the synthesis of cholesterol and fatty acids. However, its effect in the prevention / treatment of hepatic steatosis and hypertriglyceridemia has not been investigated. The aim of our work has been to elucidate whether bempedoic acid, through a mechanism other than ATP:citrate lyase inhibition, reverses these metabolic alterations. EXPERIMENTAL DESIGN: The study was carried out in female Sprague-Dawley rats fed, for three months, with a high fat diet supplemented with fructose (10% w/v) in drinking water. During the last month, bempedoic acid (30mg/kg/day) was administered to a group of animals. Zoometric and plasmatic parameters were analyzed, gene and protein expression analysis were performed in liver samples and PPAR-PPRE binding activity was determined. RESULTS: Our interventional model developed hepatic steatosis and hypertriglyceridemia. Despite an increase in total caloric intake, there was no increase in body weight of the animals. The administration of bempedoic acid significantly reduced hepatic steatosis and promoted a marked hepatocyte hypertrophy. There was a 66% increase in the liver weight of the animals treated with the drug that was not accompanied by modifications in the markers of inflammation, oxidative stress, or endoplasmic reticulum stress. Bempedoic acid activated the peroxisome proliferator activated nuclear receptor (PPARα) and its target genes.

Potencial efecto terapéutico de los polifenoles obtenidos de la cáscara de granada en la esteatosis hepática

RESUMEN Antecedentes: La enfermedad por hígado graso no alcohólico (EHGNA) tiene una elevada prevalencia a nivel mundial, y puede ir desde la esteatosis simple hasta hepatocarcinoma. Su origen es multifactorial, siendo la dieta poco saludable un factor clave en su patogenia y progresión. Los polifenoles son antioxidantes que han mostrado beneficios en el tratamiento de la EHGNA. Una fuente emergente de estos compuestos son los residuos agroindustriales, entre ellos, la cáscara de granada. La cáscara de granada tiene un alto contenido de polifenoles, específicamente de elagitaninos. Su extracto fenólico (extracto de cáscara de granada; ECG) ha mostrado efectos promisorios a nivel metabólico. Sin embargo, su uso presenta algunas limitantes que deben ser consideradas antes de recomendar su ingesta mediante alimentos funcionales o nutracéuticos para prevención o tratamiento de EHGNA. Objetivo: Discutir a partir de datos obtenidos en estudios in vitro y modelos animales, el potencial terapéutico de los polifenoles obtenidos de la cáscara de granada para prevención y tratamiento de la EHGNA. Metodología: Se realizó una búsqueda bibliográfica en bases de datos PubMed y Web of Science (2015 a la fecha) de estudios en modelos de esteatosis hepática in vitro y en animales, además de ensayos clínicos relacionados. Conclusión: Existen datos promisorios sobre el uso del ECG en alteraciones metabólicas propias de la EHGNA y esteatosis hepática, principalmente a nivel de perfil lipídico. Se deben discutir las dosis y formas de administración, con el fin de mejorar su estabilidad y biodisponibilidad. Se requieren ensayos clínicos controlados que confirmen los efectos en humanos.

ABSTRACT Background: Nonalcoholic fatty liver disease (NAFLD) has a high prevalence worldwide and can range from simple steatosis to hepatocarcinoma. Its causes are multifactorial, with an unhealthy diet being a key factor in its pathogenesis and progression. Polyphenols are antioxidants that have shown benefits in treating NAFLD. An emerging source of these compounds is agro-industrial by-products, including pomegranate peels. Pomegranate peels are high in polyphenols, specifically ellagitannins. Its polyphenolic extract (PPE) has shown promising metabolic benefits. However, its use has some limitations that must be considered before recommending its intake through functional foods or nutraceuticals to prevent or treat NAFLD. Objective: This article aims to discuss, using results from in vitro studies and animal models, the therapeutic potential of polyphenols obtained from pomegranate peels to prevent and treat NAFLD. Methods: A bibliographic search was carried out in PubMed and Web of Science databases (2015 to date) of in vitro and animal model studies of hepatic steatosis, in addition to related clinical trials. Conclusion: There are promising data on the use of PPE in metabolic disorders typical of NAFLD and hepatic steatosis, mainly improving lipid profile. Doses and vehicles of administration should be discussed to improve stability and bioavailability. Controlled clinical trials are required to confirm the effects in humans.
