RESUMO

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)


Non-alcoholic fatty liver disease or metabolic-associated fatty liver disease (MAFLD) is a common condition with increasing prevalence and incidence, specially in patients with type 2 diabetes mellitus (DM2). 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 DM2 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.(AU)

RESUMO

Background: Inflammasome activation is known to be involved in nonalcoholic steatohepatitis (NASH). Vinpocetine is a derivative of vincamine and is reported to suppress the activation of inflammasome. Methods: This study explored the therapeutical potential of Vinpocetine on NASH. Mice were fed with a choline-deficient (MCD) or chow diet in the presence or absence of Vinpocetine for 8 weeks. H&E staining and biochemical assays were determined to evaluate the hepatic steatosis and fibrosis symptoms. In addition, primary hepatocytes and Kupffer cells were isolated and induced by MCD or lipopolysaccharides/cholesterol crystals with or without Vinpocetine. ELISAs, qPCR, and Western blotting were applied to determine the levels of NASH-related biomarkers in both in vivo mouse model and in vitro cell models. Results: Treatment of Vinpocetine did not cause observable side effects against and MCD-induced cells and mouse NASH model. However, treatment of Vinpocetine ameliorated hepatic steatosis and fibrosis and suppressed the levels of alanine transaminase and aspartate transferase in the mouse NASH model. In addition, treatment of Vinpocetine suppressed the mRNA and protein levels of inflammasome components both in vitro and in vivo. Conclusion: Vinpocetine suppressed NASH in mice by mediating inflammasome components via nuclear factor κB signaling. (AU)


Antecedentes: Se sabe que la activación del inflamasoma está implicada en la esteatohepatitis no alcohólica (EHNA). La vinpocetina es un derivado de la vincamina que, según los informes, suprime la activación del inflamasoma. Métodos: Este estudio exploró el potencial terapéutico de la vinpocetina en la EHNA. Durante 8 semanas se alimentó a ratones con una dieta deficiente en colina (MCD) o con una dieta chow en presencia o ausencia de vinpocetina. Se realizaron tinciones de H&E y ensayos bioquímicos para evaluar los síntomas de esteatosis hepática y fibrosis. Además, se aislaron hepatocitos primarios y células de Kupffer y se indujeron mediante MCD o cristales de lipopolisacáridos/colesterol con o sin vinpocetina. Se aplicaron ELISA, qPCR y Western blotting para determinar los niveles de biomarcadores relacionados con la EHNA tanto en el modelo de ratón in vivo como en los modelos celulares in vitro. Resultados: El tratamiento con vinpocetina no causó efectos secundarios observables contra las células y el modelo de ratón de EHNA inducidos por MCD. Sin embargo, el tratamiento con vinpocetina mejoró la esteatosis hepática y la fibrosis y suprimió los niveles de alanina transaminasa y de aspartato transferasa en el modelo de EHNA de ratón. Además, el tratamiento con vinpocetina suprimió los niveles de ARNm y proteínas de los componentes del inflamasoma tanto in vitro como in vivo. Conclusiones: La vinpocetina suprimió la EHNA en ratones por mediación de los componentes del inflamasoma a través de la señalización del factor nuclear κB. (AU)

RESUMO

Objetivo: Evaluar el efecto hepatoprotector del consumo de Nostoc commune (cushuro) frente al daño inducido por dietas ricas en sacarosa en ratones. Métodos: El estudio tuvo un enfoque cuantitativo, experimental puro con grupo control y post prueba. Se utilizaron 28 ratones macho con un peso promedio de 30 ± 6,2 g y pulverizado de Nostoc commune. Los animales se dividieron en cuatro grupos y recibieron las siguientes dietas durante 50 días: Grupo I: dieta A (sacarosa 10%), grupo II: dieta B (sacarosa 36,5%), grupo III: dieta C (sacarosa 36,5% + cushuro 1%) y grupo IV: dieta D (sacarosa 36,5% + cushuro 3%). Finalmente se extrajo el hígado y se realizó los análisis bioquímicos e histológicos. El estadístico ANOVA se aplicó para los datos simétricos y para los asimétricos, Kruskall-Wallis. Resultados: En los grupos III y IV se observó que los niveles de triglicéridos (p<0.05) disminuyeron y también se observó una mejor conservación a nivel histológico. Conclusión: El consumo de Nostoc commune (cushuro) presenta efecto hepatoprotector expresado en la disminución de triglicéridos y la conservación a nivel histológico frente al daño inducido por dietas ricas en sacarosa en ratones.(AU)


Objective: To evaluate the hepatoprotective effect of theconsumption of Nostoc commune (cushuro) against the da-mage induced by diets rich in sucrose in mice. Methods: The study had a quantitative, pure experimen-tal approach with control group and post test. Twenty-eightmale mice with an average weight of 30 ± 6.2 g and sprayedwith Nostoc commune were used. The animals were dividedinto four groups and received the following diets for 50 days: Group I: diet A (sucrose 10%), group II: diet B (sucrose36.5%), group III: diet C (sucrose 36.5 % + cushuro 1%)and group IV: diet D (sucrose 36.5% + cushuro 3%). Finally,the liver was extracted and biochemical and histologicalanalyzes were performed. The ANOVA statistic was appliedfor symmetric data and Kruskall-Wallis for asymmetric data. Results: In groups III and IV it was observed that thetriglyceride levels (p<0.05) decreased and a better conserva-tion at the histological level was also observed. Conclusion: The consumption of Nostoc commune (cus-huro) has a hepatoprotective effect expressed in the reduction of triglycerides and conservation at the histological levelagainst the damage induced by diets rich in sucrose in mice.(AU)

RESUMO

Fatty liver index (FLI) was developed as a simple and accurate marker of hepatic steatosis. FLI is derived from an algorithm based on body mass index, waist circumference, and levels of triglycerides and gamma-glutamyltransferase, and it is widely used in clinical and epidemiological studies as a screening tool for discriminating between healthy and nonalcoholic fatty liver disease (NAFLD) subjects. However, a systematic review of the literature regarding FLI revealed that this index has more extensive relationships with biochemical and physiological parameters. FLI is associated with key parameters of lipid, protein and carbohydrate metabolism, hormones, vitamins and markers of inflammation, or oxidative stress. FLI can be a predictor or risk factor for a number of metabolic and nonmetabolic diseases and mortality. FLI is also used as an indicator for determining the effects of health-related prevention interventions, medications, and toxic substances on humans. Although in most cases, the exact mechanisms underlying these associations have not been fully elucidated, they are most often assumed to be mediated by insulin resistance, inflammation, and oxidative stress. Thus, FLI may be a promising marker of metabolic health due to its multiple associations with parameters of physiological and pathological processes. In this context, the present review summarizes the data from currently available literature on the associations between FLI and biochemical variables and physiological functions. We believe that this review will be of interest to researchers working in this area and can provide new perspectives and directions for future studies on FLI. (AU)

RESUMO

The global prevalence and incidence of non-alcoholic fatty liver disease (NAFLD) are exhibiting an increasing trend. NAFLD is characterized by a significant accumulation of lipids, though its underlying mechanism is still unknown. Here we report that high-fat diet (HFD) feeding induced hepatic steatosis in mice, which was accompanied by a reduction in the expression and function of hepatic TRPV2. Moreover, conditional knockout of TRPV2 in hepatocytes exacerbated HFD-induced hepatic steatosis. In an in vitro model of NAFLD, TRPV2 regulated lipid accumulation in HepG2 cells, and TRPV2 activation inhibited the expression of the cellular senescence markers p21 and p16, all of which were mediated by AMPK phosphorylation. Finally, we found that administration of probenecid, a TRPV2 agonist, impaired HFD-induced hepatic steatosis and suppressed HFD-induced elevation in p21 and p16. Collectively, our findings imply that hepatic TRPV2 protects against the accumulation of lipids by modulating p21 signalling. (AU)

RESUMO

Objetivo: validación de la prueba diagnóstica Fatty Liver Index (FLI) mediante un diseño transversal. Métodos: se incluyeron pacientes con diagnóstico previo de obesidad y/o diabetes en los que estaría indicado hacer una ecografía para descartar esteatosis. Se les realizó el FLI y la prueba Gold Estándar (ecografía). Tamaño muestral: se incluyeron 135 individuos. Se calculó curva ROC, el área bajo la curva y el punto de corte del FLI para la clasificación como esteatosis. Se estimó sensibilidad, especificidad, los valores predictivos positivos y negativos del FLI. Se utilizó el programa SPSS para el análisis. A todos los pacientes se les entregó una hoja informativa del estudio y se pidió consentimiento informado. Resultados: prevalencia de esteatosis del 60,7%, predominando esteatosis leve y moderada. Hubo relación significativa entre esteatosis y triglicéridos, no así para índice de masa corporal (IMC), gamma-glutamil transferasa (GGT) y perímetro abdominal. La curva ROC del FLI se mostró muy cercana a la línea media, y el área bajo la curva fue 0,666 (0,571-0,759; intervalo de confianza [IC] del 95%), que indica una capacidad predictiva del FLI baja. Considerando un punto de corte de 76 para el FLI, la sensibilidad fue del 75,6%, la especificidad del 50,94%, el valor predictivo positivo (VPP) del 70,45% y el valor predictivo negativo (VPN) del 57,45%. Los coeficientes de probabilidad positivo y negativo fueron 1,53 y 0,49, respectivamente, que indican que el FLI no puede considerarse una buena prueba para el diagnóstico de esteatosis. Conclusiones: el test FLI no predice de forma adecuada qué pacientes con diabetes y/o obesidad tendrían esteatosis asociada. Por ello, no se puede recomendar de forma generalizada el uso del FLI para el diagnóstico de esteatosis ni tampoco para sustituir la ecografía. (AU)


Aim: Validation of the FLI (Fatty Liver Index) diagnostic test by means of a cross-sectional design. Methods: Patients with a prior diagnosis of obesity and/or diabetes in whom an ultrasound would be indicated to rule out steatosis were included. The FLI and the Gold Standard test (ultrasound) were performed. Sample size: 135 individuals were included. ROC curve, area under the curve and the FLI threshold for classification as steatosis were all calculated. Sensitivity, specificity and the positive and negative predictive values for FLI were estimated. The SPSS programme was used for the analysis. All patients were given a study information sheet and informed consent was requested. Results: Prevalence of steatosis of 60.7%, with mild and moderate steatosis predominating. There was a statistically significant relationship between steatosis and triglycerides, but not for BMI (body mass index), GGT (gamma-glutamyl transferase) and abdominal perimeter. The FLI ROC curve was very close to the midline, and the area under the curve was 0.666. This reveals a low predictive capacity for FLI. Considering a threshold of 76 for the FLI, the sensitivity, specificity, positive and negative predictive values (PPV and NPV) were 75.6%, 50.94%, 70.45% and 57.45%, respectively. The Positive and Negative Likelihood Ratios were 1.53 and 0.49, respectively. This reveals that FLI cannot be deemed a good test to diagnose steatosis. Conclusions: The Fatty Liver Index test does not adequately predict patients with diabetes and/or obesity who would have associated steatosis. Therefore, the use of FLI to diagnose steatosis or to replace ultrasound cannot be recommended in general. (AU)

RESUMO

Objetivos: Describir la prevalencia de la enfermedad del hígado graso no alcohólico (EHGNA), la asociación entre el índice de fibrosis hepática 4 (FIB4) y los hallazgos en la ecografía y las características clínicas de los pacientes con artritis psoriásica. Material y métodos: Estudio transversal observacional de todos los pacientes con artritis psoriásica vistos de forma consecutiva en consulta desde el 01/01/2020 hasta el 30/11/2020. Resultados: De los 90 pacientes estudiados, la prevalencia de EHGNA fue del 56,67%. EL FIB4 presenta asociación con la ecografía (p=0,030), la ausencia de entesitis (p=0,036) y la mayor duración de la enfermedad (Rho 0,213, p=0,042). También con la presencia de hipertensión (p=0,027) y el consumo de alcohol (p=0,021). Sin embargo, el tratamiento biológico puede considerarse como un factor protector (p=0,005). El FIB4 actúa como predictor de EHGNA con una sensibilidad del 69,2% y una especificidad del 70,4%. Conclusiones: La prevalencia de EHGNA fue superior a la población general. El índice FIB4 puede ser una herramienta válida en el cribado de EHGNA en nuestra práctica clínica diaria.(AU)


Objectives: To describe the prevalence of non-alcoholic fatty liver disease (NAFLD), the association between Liver fibrosis 4 score (FIB4) and ultrasound findings, and the clinical characteristics of psoriatic arthritis patients. Material and methods: We carried out an observational cross-sectional study of patients seen in the outpatient clinic from January 1st, 2020, to November 30th, 2020, with psoriatic arthritis. Results: Of the 90 patients studied, the prevalence of NAFLD was 56.67%. FIB4 presents an association with ultrasound findings (p=.030), the absence of enthesitis (p=.036), and longer duration of disease (Rho .213 p=.042). It also presents an association with hypertension (p=.027) and alcohol consumption (p=.021). However, biological treatment can be considered as a protective factor (p=.005). FIB4 acts as a NAFLD predictor with 69.2% sensitivity and 70.4% specificity.Conclusion: The prevalence of NAFLD was higher in our sample than in the standard population. FIB4 index may be useful in screening for silent liver damage in psoriatic arthritis in clinical practice.(AU)

RESUMO

Introduction: metabolic syndrome comprises a combination of diabetes, high blood pressure, and obesity, and metabolic associated fatty liver disease (MAFLD) is associated with it. Objective: to evaluate the effect of supplementation with S-adenosyl-L-methionine + N-acetylcysteine + thioctic acid + vitamin B6 (MetioNac®) for 3 months on lipidic and biochemical parameters in subjects with metabolic syndrome and at risk of MAFLD. The reduction in body weight and the oxidative stress markers malondialdehyde (MDA) and superoxide dismutase (SOD) were also evaluated. Methods: patients with metabolic syndrome, at risk of MAFLD (FIB-4 < 1.30), and with an indication for weight reduction were recruited (n = 15). Control group followed a semipersonalized Mediterranean diet (MD) for weight reduction, according to the recommendations of the Spanish Society for the Study of Obesity (SEEDO). Experimental group, in addition to the MD, took three capsules of MetioNac® supplement per day. Results: compared with the control group, subjects taking MetioNac® showed significant (p < 0.05) reductions in the levels of TG and VLDL-c, as well as in total cholesterol, LDL-c, and glucose levels. They also showed increased levels of HDL-c. Levels of AST and ALT decreased after the intervention with MetioNac®, but this decrease did not reach statistical significance. Weight loss was observed in both groups. Conclusion: supplementation with MetioNac® may be protective against hyperlipidemia, insulin resistance, and overweight among metabolic syndrome patients. Further studies on this issue are needed in a larger population.(AU)


Introducción: el síndrome metabólico se define como una combinación de diabetes, hipertensión arterial y obesidad, que se asocia con laenfermedad del hígado graso asociada a disfunción metabólica.Objetivo: evaluar el efecto de la suplementación con S-adenosil-L-metionina + N-acetilcisteína + ácido tióctico + vitamina B6 (MetioNac®)durante 3 meses sobre parámetros lipídicos y bioquímicos en sujetos con síndrome metabólico y en riesgo de enfermedad del hígado grasoasociada a disfunción metabólica. También se evaluaron la reducción del peso corporal y los marcadores de estrés oxidativo malondialdehído(MDA) y superóxido dismutasa (SOD).Métodos: se reclutaron pacientes con síndrome metabólico, riesgo de enfermedad del hígado graso asociada a disfunción metabólica (FIB-4 < 1,30) y con indicación de reducción de peso (n = 15). El grupo control siguió una dieta mediterránea (DM) semipersonalizada para la reducciónde peso, de acuerdo con las recomendaciones de la Sociedad Española para el Estudio de la Obesidad (SEEDO). El grupo intervención, ademásde la DM, tomó tres cápsulas diarias de MetioNac®.Resultados: en comparación con el grupo de control, los sujetos que tomaron MetioNac® mostraron reducciones significativas (p < 0.05) en losniveles de TG y VLDL-c, así como en los niveles de colesterol total, LDL-c y glucosa. También mostraron niveles elevados de HDL-c. Los nivelesde AST y ALT disminuyeron después de la intervención con MetioNac®, pero esta disminución no fue estadísticamente significativa. También seobservó una pérdida de peso en ambos grupos.Conclusión: la suplementación con MetioNac® puede proteger contra la hiperlipidemia, la insulinorresistencia y el sobrepeso en pacientes consíndrome metabólico. Sin embargo, es necesario realizar más estudios y seleccionar un mayor número de participantes.(AU)

RESUMO

FUNDAMENTOS: La enfermedad hepática grasa asociada a disfunción metabólica (MAFLD) es una enfermedad poco considerada,que ha recibido atención debido al número de casos en países como México, donde ocupa el 4º lugar mundial de incidencia. La MAFLDse desarrolla en personas con sobrepeso u obesidad y se caracteriza por la acumulación de triglicéridos en el hígado, donde puedeevolucionar hacia carcinoma hepatocelular. Se ha observado que la MAFLD depende de la genética y del estilo de vida. Tomando encuenta la alta prevalencia de MAFLD en la población hispana, nos enfocamos en este trabajo en estudiar la prevalencia y características relacionadas con esta enfermedad en pacientes mexicanos. MÉTODOS: En este estudio se incluyeron 572 pacientes con sobrepeso u obesidad, a los cuales se les realizó un análisis de cribadomediante el índice de hígado graso (IHG), se analizaron parámetros clínicos, demográficos y comorbilidades. Se obtuvieron frecuenciasde las variables y se analizaron los datos mediante chi cuadrado o exacta de Fisher, razón de momios (OR) y regresión logística binaria. RESULTADOS: Se obtuvo una prevalencia del 37% de MAFLD, donde la historia familiar de obesidad, el uso de paracetamol, así comoel consumo de carbohidratos y grasas fueron factores de riesgo para su desarrollo. Se encontró que la hipertensión arterial, la obesidadvisceral y la hipertrigliceridemia también estaban asociados al desarrollo de la MAFLD. Por otro lado, el ejercicio fue un factor protector. CONCLUSIONES: Nuestros resultados ponen de manifiesto la necesidad de realizar estudios relacionados con las causalidades dela MAFLD en los pacientes mexicanos, principalmente en el uso del paracetamol.(AU)


BACKGROUND: Metabolic dysfunction-associated fatty liver disease (MAFLD) is a poor attended disease, which has gained at-tention due the elevated number of cases in countries as Mexico, where the incidence is the number 4 th globally. MAFLD developsin obese or overweighted individuals and is characterized by triglycerides accumulation in the liver, this condition can develop tohepatocellular carcinoma. It has been observed that MAFLD depends on the genetics and lifestyle. Due to the high prevalence of thisdisease among Hispanic population, we focused on this study in the characteristics and prevalence of MAFLD in Mexican patients. METHODS: In this study were included 572 overweighted and obese patients, who underwent a screening analysis using the fatty liverindex (IHG), clinical parameters were analysed, demographic and comorbidities. Frequency of variables were obtained, and the data wereanalysed by Chi-square test or Fisher test, odd ratio (OR) and binary logistic regression. RESULTS: A MALFD prevalence of 37% were obtained, where the history of familiar obesity, paracetamol usage, carbohydrate andfat intake are shown to be risk factors. It was found that high blood pressure, central obesity and hypertriglyceridemia were alsoassociated to the MAFLD development. On the other hand, physical exercise was a protector factor. CONCLUSIONS: Our results show the necessity to study the MAFLD causalities in Mexican patients, focused on the paracetamol intake.(AU)

RESUMO

Lysosomal acid lipase (LAL) deficiency is a rare, autosomal recessive disease caused by mutations in the LIPA gene, which produces cholesteryl ester and triglyceride accumulation predominantly in hepatocytes, adrenal glands, and gastrointestinal tract. We describe two new cases occurring in siblings, aged 5 and 7 years, who presented with hepatomegaly, dyslipidemia, and abnormal liver function. Percutaneous liver biopsy revealed portal inflammation, hypertrophic Kupffer cells with a foamy appearance and microvesicular steatosis with fibrosis. Immunostaining for lysosomal markers, cathepsin D and LAMP1 reflected the lysosomal nature of the lipid vacuoles. After enzymatic confirmation, enzyme replacement therapy was initiated for both siblings. Follow-up transaminase levels and lipid profiles showed a notable decrease in AST and ALT and a slight increase in HDL cholesterol. It is crucial to increase awareness of this rare condition among clinicians and pathologists. The expression of lysosomal markers around the lipid vacuoles might help diagnose LAL deficiency in pediatric patients.(AU)


La deficiencia de lipasa ácida lisosomal (LAL) es una enfermedad autosómica recesiva inusual, causada por mutaciones en el gen LIPA, que genera acumulación de éster de colesterol y triglicéridos predominantemente en hepatocitos, glándulas suprarrenales y tracto gastrointestinal. Describimos 2 casos adicionales que ocurrieron en 2 hermanos, de 5 y 7 años, que presentaron hepatomegalia, dislipidemia y función hepática anormal. La biopsia hepática percutánea reveló inflamación portal leve, células de Kupffer hipertróficas, con un aspecto espumoso y esteatosis microvesicular difusa con fibrosis. La inmunotinción de marcadores lisosomales, catepsina D y LAMP1, reflejó la naturaleza lisosomal de las vacuolas lipídicas. Después de la confirmación enzimática, ambos hermanos iniciaron terapia de reemplazo enzimático. Los niveles de transaminasas y los perfiles lipídicos de seguimiento mostraron una disminución notoria en AST y ALT y un ligero aumento en el colesterol HDL. Es crucial aumentar la conciencia de esta inusual condición entre médicos y patólogos. La expresión de marcadores lisosomales alrededor de las vacuolas lipídicas podría ayudar a diagnosticar la deficiencia de LAL en pacientes pediátricos.(AU)

RESUMO

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)
