ABSTRACT

Introducción. La obesidad infantil puede causar hiperlipidemia y esteatosis hepática y complicaciones crónicas. Nuestro objetivo fue evaluar la relación entre el espesor de la grasa subcutánea abdominal (GSA) y la esteatosis hepática, las transaminasas y los lípidos séricos en niños obesos.Población y métodos. Estudio retrospectivo en niños (4-18 años) que acudieron a los consultorios externos. Se evaluaron las asociaciones entre el espesor de la GSA mediante ecografía y la esteatosis hepática, alanina aminotransferasa (ALT), aspartato aminotransferasa (AST) y el perfil lipídico sérico.Resultados. Se identificaron 95 niños con esteatosis hepática; el grado 1 fue el más frecuente (73,6 %, n: 70), seguido del grado 2 (21,1 %) y del 3 (5,3 %). El espesor medio (en mm) de la GSA de línea media y flancos fue 38,48 ± 11,53 y 20,91 ± 8,00 en grado 1; 41,23 ± 10,03 y 19,84 ± 6,75 en grado 2, y 63,12 ± 12,08 y 23,22 ± 5,92 en grado 3, respectivamente. El espesor de la GSA de línea media y flancos se correlacionó positivamente con triglicéridos en grado 3; el espesor de la GSA de línea media se correlacionó con el índice de masa corporal, colesterol total, colesterol LDL y AST (r: 0,9; p: 0,037; r: 0,648; p: 0,001; r: 0,387; p: 0,001; r: 0,406; p: 0,001; r: 0,463; p: 0,001; respectivamente) en grado 1.Conclusión. El espesor de la GSA mediante ecografía puede predecir hiperlipidemia en niños obesos con esteatosis hepática de grado 3 e hipercolesterolemia en grado 1.


Introduction. Childhood obesity can cause hyperlipidemia and hepatic steatosis at early age and chronic disease complications in adult life. We aimed to evaluate the relationship between abdominal subcutaneous fat thickness (ASFT) and hepatic steatosis, serum lipid and transaminase levels in obese children.Population and methods. A retrospective study was conducted with children (aged 4-18 years) who presented to outpatient clinic due to obesity. Associations between ASFT as assessed by ultrasonography (US) and hepatic steatosis, alanine transaminase (ALT), aspartate transaminase (AST) and serum lipid profile were evaluated.Results. We identified 95 children, all of which were diagnosed as having hepatic steatosis; the most common type was grade 1 (73.6 %, n: 70), followed by grade 2 (21.1 %) and grade 3 (5.3 %). The mean values of midline and flank ASFT were measured as 38.48 ± 11.53 mm and 20.91 ± 8.00 mm in grade 1; 41.23 ± 10.03 and 19.84 ± 6.75 in grade 2 and 63.12 ± 12.08 and 23.22 ± 5.92 in grade 3 hepatic steatosis, respectively. Midline and flank ASFT correlated positively with triglycerides in grade 3 steatosis, while midline ASFT correlated with body mass index, total cholesterol, low-density lipoprotein cholesterol, and AST (r: 0.9; p: 0.037; r: 0.648, p: 0.001; r: 0.387, p: 0.001; r: 0.406, p: 0.001, r: 0.463, p: 0.001; respectively) in grade 1 steatosis.Conclusion. ASFT as assessed by US may be of predictive value for hyperlipidemia in grade 3 and for hypercholesterolemia in grade 1 hepatic steatosis in obese children.

ABSTRACT

Resumen Introducción. La lipodistrofia congénita generalizada (LCG) es un síndrome genético autosómico recesivo extremadamente raro que se caracteriza por ausencia generalizada de tejido adiposo, deficiencia en la producción de hormonas como la leptina y complicaciones metabólicas potencialmente serias como diabetes mellitus tipo 2 (DM2), esteatohepatitis e hipertrigliceridemia. Presentación del caso. Paciente femenina de 17 años con un diagnóstico tardío de LCG y con diabetes mellitus (erróneamente clasificada como tipo I), hipertrigliceridemia severa e infecciones a repetición. Luego de introducir metformina y un inhibidor del SGLT2 en el manejo de la paciente, se logró un adecuado control metabólico. Conclusión. Con frecuencia, el desconocimiento de algunas enfermedades huérfanas lleva a diagnósticos erróneos y, por tanto, a tratamientos inadecuados que en algunos casos pueden empeorar la condición clínica de los pacientes. Por lo anterior, en el caso de la LCG, es necesario que la comunidad médica tenga una mejor comprensión de sus aspectos diagnósticos y terapéuticos para brindar un diagnóstico y tratamiento oportunos.


Abstract Introduction: Generalized congenital lipodystrophy (GDL) is an extremely rare autosomal recessive genetic syndrome characterized by generalized absence of adipose tissue, deficient production of hormones such as leptin, and potentially serious metabolic complications such as type 2 diabetes mellitus (DM2), steatohepatitis and hypertriglyceridemia. Case presentation: This is the case of a 17-year-old female patient with a late diagnosis of GDL and with diabetes mellitus (erroneously classified as type 1), severe hypertriglyceridemia and recurrent infections. Adequate metabolic control was achieved after the introduction of metformin and an SGLT2 inhibitor. Conclusion: Lack of knowledge about some orphan diseases usually leads to misdiagnosis and, therefore, to inadequate treatments that may worsen the clinical condition of patients. Therefore, in the case of GDL, the medical community should have a better understanding of its diagnostic and therapeutic aspects in order to provide timely diagnosis and treatment.

ABSTRACT

ABSTRACT Fat infiltration in the pancreas is called pancreatic steatosis and it has several synonyms such as pancreatic lipomatosis, non-alcoholic fatty pancreatic disease, lipomatous pseudohypertrophy, fatty replacement, fatty pancreas and fatty infiltration. Pancreatic steatosis describes a disease ranging from infiltration of fat in the pancreas to pancreatic inflammation, and development of pancreatic fibrosis. There are multiple aetiologies of this condition, such as metabolic syndrome, alcohol intake, viral infections, toxins, congenital syndromes, etc. Pancreatic steatosis is usually diagnosed by trans-abdominal ultrasound, computed tomography scan and magnetic resonance imaging. Fatty infiltration in pancreas may lead to pancreatitis, diabetes mellitus and may be a predisposing cause of pancreatic cancer. Now a day, pancreatic steatosis is a common incidental finding during abdominal ultrasonography for other reasons and is a new challenge in Gastroenterology. But there is no guideline for pancreatic steatosis till now. In this review article, we are trying to give an overall idea (aetiologies, diagnosis, management, clinical significances) on pancreatic steatosis.


RESUMO A infiltração de gordura no pâncreas é chamada de esteatose pancreática ou lipomatose pancreática e tem vários sinônimos tais como: doença pancreática gordurosa não alcoólica, pseudo hipertrofia lipomatosa, reposição gordurosa, pâncreas gorduroso e infiltração gordurosa. A esteatose pancreática descreve uma doença que vai desde a infiltração de gordura no pâncreas até a inflamação pancreática com o desenvolvimento de fibrose pancreática. Existem múltiplas causas dessa condição, como síndrome metabólica, ingestão de álcool, infecções virais, toxinas, síndromes congênitas, etc. A esteatose pancreática é geralmente diagnosticada por ultrassom trans-abdominal, tomografia computadorizada ou ressonância magnética. A infiltração gordurosa no pâncreas pode levar à pancreatite e pode ser uma causa predisponente ao câncer de pâncreas. Hoje em dia, a fibrose pancreática é um achado incidental comum durante a ultrassonografia abdominal realizada por outras razões e é um novo desafio na Gastroenterologia. Mas não há diretriz para esteatose pancreática até agora. Neste artigo de revisão, objetivamos dar uma ideia geral sobre esteatose pancreática.

ABSTRACT

BACKGROUND: We evaluated the association of visceral-to-subcutaneous fat ratio (VSR) with nonalcoholic fatty liver disease (NAFLD) and advanced fibrosis degree based on noninvasive serum fibrosis markers in the general population with NAFLD.METHODS: This is a cross-sectional study, in 7,465 Korean adults who underwent health screening examinations. NAFLD was defined as fatty liver detected on ultrasonography, and visceral and subcutaneous abdominal fat was measured using computed tomography. We predicted fibrosis based on the fibrosis-4 (FIB-4) score and aspartate aminotransferase-to-platelet ratio index (APRI) and categorized the risk for advanced fibrosis as low, indeterminate, or high.RESULTS: The multivariable-adjusted prevalence ratios for indeterminate to high risk of advanced fibrosis based on FIB-4, determined by comparing the second, third, and fourth quartiles with the first quartile of VSR, were 3.38 (95% confidence interval [CI], 0.64 to 17.97), 9.41 (95% CI, 1.97 to 45.01), and 19.34 (95% CI, 4.06 to 92.18), respectively. The multivariable-adjusted prevalence ratios for intermediate to high degree of fibrosis according to APRI also increased across VSR quartiles (5.04 [95% CI, 2.65 to 9.59], 7.51 [95% CI, 3.91 to 14.42], and 19.55 [95% CI, 9.97 to 38.34], respectively). High VSR was more strongly associated with the prevalence of NAFLD in nonobese subjects than in obese subjects, and the associations between VSR and intermediate to high probability of advanced fibrosis in NAFLD were stronger in obese subjects than in nonobese subjects.CONCLUSION: High VSR values predicted increased NAFLD risk and advanced fibrosis risk with NAFLD, and the predictive value of VSR for indeterminate to high risk of advanced fibrosis was higher in obese subjects than in nonobese subjects.

ABSTRACT

A boy, aged 66 days, was admitted to the hospital due to subcutaneous nodules for 46 days and abdominal distension for 10 days. The main clinical manifestations were loss of adipose tissue, subcutaneous nodules, insulin-resistant diabetes, hypertriglyceridemia, and hepatic steatosis. The boy was diagnosed with congenital generalized lipodystrophy type 1 (CGL1). His condition was improved after administration of middle-chain fatty acid formula milk and insulin injection or oral metformin. Gene testing revealed a homozygous mutation, c.646A>T, in the AGPAT2 gene, and both his parents were carriers of this mutation. This case of CGL1 has the youngest age of onset ever reported in China and multiple subcutaneous nodules as the initial symptom.

ABSTRACT

Ceramides are minor components of the hepatic lipidome that have major effects on liver function. These products of lipid and protein metabolism accumulate when the energy needs of the hepatocyte have been met and its storage capacity is full, such that free fatty acids start to couple to the sphingoid backbone rather than the glycerol moiety that is the scaffold for glycerolipids (e.g., triglycerides) or the carnitine moiety that shunts them into mitochondria. As ceramides accrue, they initiate actions that protect cells from acute increases in detergent-like fatty acids; for example, they alter cellular substrate preference from glucose to lipids and they enhance triglyceride storage. When prolonged, these ceramide actions cause insulin resistance and hepatic steatosis, 2 of the underlying drivers of cardiometabolic diseases. Herein the author discusses the mechanisms linking ceramides to the development of insulin resistance, hepatosteatosis and resultant cardiometabolic disorders.

ABSTRACT

Like other bodily materials, lipids such as plasma triacylglycerol, cholesterols, and free fatty acids are in a dynamic state of constant turnover (i.e., synthesis, breakdown, oxidation, and/or conversion to other compounds) as essential processes for achieving dynamic homeostasis in the body. However, dysregulation of lipid turnover can lead to clinical conditions such as obesity, fatty liver disease, and dyslipidemia. Assessment of “snap-shot” information on lipid metabolism (e.g., tissue contents of lipids, abundance of mRNA and protein and/or signaling molecules) are often used in clinical and research settings, and can help to understand one's health and disease status. However, such “snapshots” do not provide critical information on dynamic nature of lipid metabolism, and therefore may miss “true” origin of the dysregulation implicated in related diseases. In this regard, stable isotope tracer methodology can provide the in vivo kinetic information of lipid metabolism. Combining with “static” information, knowledge of lipid kinetics can enable the acquisition of in depth understanding of lipid metabolism in relation to various health and disease status. This in turn facilitates the development of effective therapeutic approaches (e.g., exercise, nutrition, and/or drugs). In this review we will discuss 1) the importance of obtaining kinetic information for a better understanding of lipid metabolism, 2) basic principles of stable isotope tracer methodologies that enable exploration of “lipid kinetics” in vivo, and 3) quantification of some aspects of lipid kinetics in vivo with numerical examples.

ABSTRACT

ABSTRACT Objective To investigate the effects of sericin extracted from silkworm Bombyx mori cocoon on morphophysiological parameters in mice with obesity induced by high-fat diet. Methods Male C57Bl6 mice aged 9 weeks were allocated to one of two groups - Control and Obese, and fed a standard or high-fat diet for 10 weeks, respectively. Mice were then further subdivided into four groups with seven mice each, as follows: Control, Control-Sericin, Obese, and Obese-Sericin. The standard or high fat diet was given for 4 more weeks; sericin (1,000mg/kg body weight) was given orally to mice in the Control-Sericin and Obese-Sericin Groups during this period. Weight gain, food intake, fecal weight, fecal lipid content, gut motility and glucose tolerance were monitored. At the end of experimental period, plasma was collected for biochemical analysis. Samples of white adipose tissue, liver and jejunum were collected and processed for light microscopy analysis; liver fragments were used for lipid content determination. Results Obese mice experienced significantly greater weight gain and fat accumulation and had higher total cholesterol and glucose levels compared to controls. Retroperitoneal and periepididymal adipocyte hypertrophy, development of hepatic steatosis, increased cholesterol and triglyceride levels and morphometric changes in the jejunal wall were observed. Conclusion Physiological changes induced by obesity were not fully reverted by sericin; however, sericin treatment restored jejunal morphometry and increased lipid excretion in feces in obese mice, suggesting potential anti-obesity effects.


RESUMO Objetivo Investigar os efeitos da sericina extraída de casulos de Bombyx mori na morfofisiologia de camundongos com obesidade induzida por dieta hiperlipídica. Métodos Camundongos machos C57Bl6, com 9 semanas de idade, foram distribuídos em Grupos Controle e Obeso, que receberam ração padrão para roedores ou dieta hiperlipídica por 10 semanas, respectivamente. Posteriormente, os animais foram redistribuídos em quatro grupos, com sete animais cada: Controle, Controle-Sericina, Obeso e Obeso-Sericina. Os animais permaneceram recebendo ração padrão ou hiperlipídica por 4 semanas, período no qual a sericina foi administrada oralmente na dose de 1.000mg/kg de massa corporal aos Grupos Controle-Sericina e Obeso-Sericina. Parâmetros fisiológicos, como ganho de peso, consumo alimentar, peso das fezes em análise de lipídios fecais, motilidade intestinal e tolerância à glicose foram monitorados. Ao término do experimento, o plasma foi coletado para dosagens bioquímicas e fragmentos de tecido adiposo branco; fígado e jejuno foram processados para análises histológicas, e amostras hepáticas foram usadas para determinação lipídica. Resultados Camundongos obesos apresentaram ganho de peso e acúmulo de gordura significativamente maior que os controles, aumento do colesterol total e glicemia. Houve hipertrofia dos adipócitos retroperitoneais e periepididimais, instalação de esteatose e aumento do colesterol e triglicerídeos hepáticos, bem como alteração morfométrica da parede jejunal. Conclusão O tratamento com sericina não reverteu todas as alterações fisiológicas promovidas pela obesidade, mas restaurou a morfometria jejunal e aumentou a quantidade de lipídios eliminados nas fezes dos camundongos obesos, apresentando-se como potencial tratamento para a obesidade.

ABSTRACT

A obesidade infantil é uma epidemia mundial. São várias as comorbidades associadas à obesidade, destacando-se a doença hepática gordurosa não alcoólica (DHGNA), um termo abrangente que envolve desde a esteatose hepatocelular simples até quadros mais avançados de esteato-hepatite, fibrose e cirrose hepática. Atualmente, é a segunda maior causa de transplante hepático em adultos nos Estados Unidos, com potencial de se tornar a primeira nas próximas décadas. Associado a este panorama, ainda existe o desafio do diagnóstico, uma vez que os critérios clínicos e laboratoriais ainda são controversos, especialmente em crianças. A biópsia é o padrão ouro, entretanto é um procedimento invasivo e sujeito a riscos. Por isso, a dosagem de enzimas hepáticas e a ultrassonografia abdominal são utilizadas para triagem e avaliação, apesar de suas limitações. O tratamento de DHGNA deve obrigatoriamente incluir a abordagem da obesidade. Por isso, os pilares do tratamento envolvem a mudança do estilo de vida e dos hábitos alimentares. Embora a eficácia de várias medicações venha sendo estudada, a alimentação saudável e a atividade física permanecem como a mais importante estratégia de prevenção e tratamento da DHGNA na infância e adolescência. A equipe multidisciplinar deve, junto ao paciente e a família, construir uma rotina de hábitos alimentares e atividades físicas adequadas para cada caso. (AU)


Childhood obesity is a worldwide epidemic. There are several comorbidities associated with obesity, including non-alcoholic fatty liver disease (NAFLD), a wide term that ranges from a hepatocellular steatosis to more advanced steatohepatitis, fibrosis and liver cirrhosis. This is the second major cause of liver transplant in adults in the United States, with the potential to become the first one in the next few decades. Associated with this scenario, the challenge of diagnosis still exists, since screening is still controversial, especially in children. Biopsy is the gold standard, but it is an invasive and risky procedure. Therefore liver enzymes and abdominal ultrasound are used for screening and assessment although their limitations. Treatment of NAFLD should involve an approach to obesity with focus in lifestyle intervention and healthy diet. While the efficacy of several medications has been investigated in children, healthy diet and physical activity remain the only prevention and treatment strategies for paediatric NAFLD. A multidisciplinary team should, together with the patient and a family, build a routine of healthy eating and physical activities (AU)

ABSTRACT

Abstract Background: In view of the increased global prevalence of cardiovascular and hepatic diseases, the diet lipid content and its relationship with the accumulation of fat in hepatocytes have been investigated as key factors in preventing these diseases. Objective: To evaluate the metabolic effects of a high-lard diet supplemented or not with cholesterol on a modified dyslipidemia model. Methods: We divided 24 adult male Wistar rats into three groups: standard diet (STD - 4% lipids), high-lard diet (HLD - 21% lard), and high-lard and high-cholesterol diet (HL/HCD - 20% lard, 1% cholesterol, 0.1% cholic acid). After six weeks of treatment, blood and liver were collected for biochemical (serum lipid profile and liver enzymes) and morphological analyses. Statistical analysis included one-way analysis of variance (ANOVA), followed by Tukey test for mean comparisons, and a 5% probability was considered statistically significant. Results: Animals fed HL/HCD showed increased total cholesterol, triacylglycerol, LDL-c, non-HDL-c, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) serum levels compared to those fed STD. In addition, the HL/HCD animals presented higher relative liver weight, with moderate macrovesicular hepatic steatosis and inflammatory infiltrate. Conclusion: A high-fat diet with lard (20%) and cholesterol (1%) triggered dyslipidemia with severe liver damage in rats in a shorter experimental time than the previously reported models. The high-lard diet without supplementation of cholesterol led to body weight gain, but not to dyslipidemia.


Resumo Fundamento: Tendo em vista o aumento da prevalência global de doenças cardiovasculares e hepáticas, o conteúdo lipídico da dieta e sua relação com o acúmulo de gordura nos hepatócitos têm sido investigados como fatores-chave na prevenção dessas doenças. Objetivo: Avaliar os efeitos metabólicos de uma dieta rica em banha suplementada com colesterol ou não, em um modelo modificado de dislipidemia. Métodos: Foram divididos 24 ratos Wistar machos adultos em três grupos: dieta padrão (DP - 4% de lipídios), dieta rica em banha (DRB - 21% de banha) e dieta rica em banha e colesterol (DRB/RC - 20% de banha, 1% de colesterol e 0,1% de ácido cólico). Após seis semanas de tratamento, o sangue e o fígado foram coletados para análises bioquímicas (perfil lipídico sérico e enzimas hepáticas) e morfológicas. A análise estatística incluiu análise de variância unidirecional (ANOVA), seguida do teste de Tukey para comparações de médias. Uma probabilidade de 5% foi considerada estatisticamente significativa. Resultados: Animais alimentados com DRB/RC apresentaram um aumento nos níveis séricos de colesterol total, triacilglicerol, LDL-c, não-HDL-c, alanina aminotransferase (ALT) e aspartato aminotransferase (AST) em comparação com aqueles alimentados com DP. Além disso, os animais tratados com DRB/RC apresentaram um peso relativo do fígado maior, com esteatose hepática macrovesicular moderada e infiltrado inflamatório. Conclusão: Uma dieta rica em gordura com banha (20%) e colesterol (1%) desencadeou dislipidemia com danos graves ao fígado em ratos em um tempo experimental menor do que os modelos previamente relatados. A dieta rica em banha sem suplementação de colesterol levou ao ganho de peso corporal, mas não à dislipidemia.

ABSTRACT

One of the key functions of the hepatobiliary system is bile formation. Aquaporins (AQPs) are likely to play a role in water transport that is essential for appropriate hepatobiliary tract function. The increasing prevalence of fatty liver parallels the rise of obesity and its complications over the past several decades. In this paper, general morphology observation, histopathology and AQP1 immunohistochemical expression were observed in livers of the high-fat diet (HFD) rats. For the liver of HFD rats, immunolight microscopy revealed weak labeling of AQP1 on the surface of central veins and liver sinusoid compared with the normal diet (ND) rats. It was suggested that bile secreted by the liver of HFD rats was maybe abnormal, thereby causing abnormalities in the composition and secretion of bile. However, the deeper understanding of mechanisms involved to the fatty liver is still unclear, in particular AQPs in the liver of obesity, additional studies would be required to study the signalling cascades involved in these processes.


Una de las funciones clave del sistema hepatobiliar es la formación de bilis. Es probable que las acuaporinas (AQP) desempeñen un papel en el transporte de agua que es esencial para la función apropiada del tracto hepatobiliar. En las últimas décadas, la creciente prevalencia de hígado graso es paralela al aumento de la obesidad y sus complicaciones. En este trabajo, se identificaron características morfológicas generales, histopatología y expresión inmunohistoquímica de AQP1 en hígados de ratas con dieta rica en grasas (DRG). En el hígado de ratas con DRG, la expresión inmunohistoquímica determinó un marcaje débil de AQP1 en la superficie de las venas centrales y del sinusoide hepático en comparación con las ratas de dieta normal (DN). Se sugirió que la bilis secretada por el hígado de ratas con DRG era tal vez anormal, lo que causaba anomalías en la composición y secreción de la bilis. Sin embargo, se necesita un conocimiento mayor de los mecanismos involucrados en el hígado graso, en particular de las AQP y se requieren estudios adicionales para determinar las cascadas de señalización involucradas en estos procesos.

ABSTRACT

This study evaluated the relationships between anthropometric, dietary, motivational, and psychosocial variables among children and adolescents with overweight and non-alcoholic fatty liver disease (NAFLD). We evaluated 45 participants (6-17 years) in anthropometric terms, nutritional consumption, motivation for treatment, and family psychosocial risk by using statistical analyses (Student's t-Test or Chi-Square). It was detected that 37.8% of the families had a high psychosocial risk, 82.2% were obese, 33.3% with NAFLD, high motivation (93.3%), but low adherence to treatment (2.4%). Participants with NAFLD presented higher psychosocial risk, significantly greater obesity severity, waist and neck circumference, and Body Mass Index. They reported lower adherence to treatment, high carbohydrate consumption, ultra-processed products, high energy density, and low fiber, with poor nutritional quality. Interventions should consider the motivation for treatment and psychosocial risks, especially in cases with NAFLD.


Este estudo analisou as relações entre variáveis antropométricas, dietéticas, motivacionais e psicossociais em crianças e adolescentes com excesso de peso e esteatose hepática não alcoólica (EHNA). Avaliou-se 45 pacientes (6-17 anos) em termos antropométricos, de consumo nutricional, motivação para o tratamento e risco psicossocial familiar, com análises estatísticas (Teste t de Student ou Qui-Quadrado). Observou-se que 37,8% das famílias tinham alto risco psicossocial, 82,2% da amostra estavam obesos, 33,3% com EHNA, alta motivação (93,3%), mas uma baixa adesão ao tratamento (2,4%). Os participantes com EHNA apresentaram maior risco psicossocial, significativamente maior gravidade da obesidade, circunferência da cintura e pescoço, e Índice de Massa Corporal. Eles relataram menor adesão ao tratamento, alto consumo de carboidratos, produtos ultraprocessados, de alta densidade energética e com baixa quantidade de fibras, com pior qualidade nutricional. As intervenções devem considerar a motivação para o tratamento e os riscos psicossociais, especialmente nos casos com EHNA.

ABSTRACT

Resumen: El hígado graso agudo del embarazo es una de las alteraciones hepáticas con mayor mortalidad (cerca del 18%) presentes en la gestación, aunque es una patología poco frecuente: 1 de cada 7000 a 16.000 embarazos presenta muchas complicaciones y requiere un manejo inmediato para evitar la muerte de la gestante o del feto; sin embargo esta patología se puede enmascarar con la preeclampsia, que es otra patología hepática de mayor frecuencia, lo cual retrasa el manejo y aumenta el número de complicaciones. El objetivo de este artículo es realizar una búsqueda bibliográfica acerca del hígado graso agudo del embarazo e identificar los factores similares entre esta patología y la preeclampsia severa para lograr hacer un diagnóstico y manejo oportunos. Para ello se realizó una búsqueda sistemática en las bases de datos, PubMed, Science Direct, Medline, Embase, en junio de 2017; además, se seleccionaron artículos originales, reportes de casos y artículos de revisión, publicados en los últimos diez años.


Abstract: Acute fatty liver of pregnancy (AFLP) is one of the liver disorders with the highest mortality rate (about 18%) during pregnancy, although it is rare: 1 in 7,000 to 16,000 pregnancies has many complications and requires immediate treatment to avoid the death of the pregnant woman or the fetus. However, this pathology can be masked by preeclampsia, which is another more frequent liver disease. This delays treatment and increases the number of complications. The aim of this article is to conduct a bibliographic search about AFLP and identify similar factors between this pathology and severe preeclampsia to make a diagnosis and provide treatment in a timely manner. For this, a systematic search was carried out in databases (PubMed, Science Direct, Medline, Embase) in June 2017. In addition, original articles, case reports, and review articles published in the last ten years were selected.


Resumo: O fígado gorduroso agudo da gestação é uma das alterações hepáticas com mais mortalidade (cerca de 18 %) presentes na gravidez, embora seja uma patologia pouco frequente: 1 de cada 7.000 a 16.000 gestações apresenta muitas complicações e requer uma ação imediata para evitar a morte da gestante ou do feto. Contudo, essa patologia pode ser camuflada com a pré-eclâmpsia, que é outra patologia hepática de maior frequência, o que atrasa seu tratamento e aumenta o número de complicações. Nesse sentido, o objetivo deste estudo é realizar uma busca bibliográfica sobre o fígado gorduroso agudo da gestação e identificar os fatores semelhantes entre ele e a pré-eclâmpsia grave para poder fazer um diagnóstico e tratamento oportunos. Para isso, foi realizada uma busca sistemática nas bases de dados, PubMed, Science Direct, Medline, Embase, em junho de 2017, das quais foram selecionados artigos originais, relatos de caso e artigos de revisão, publicados nos últimos dez anos.

ABSTRACT

Introduction : La stéatose hépatique (SH) est un facteur aggravant de l'évolution des hépatites vi-rales chroniques. Le but de ce travail était d'étudier la prévalence et les facteurs associés à la stéa-tose hépatique chez les patients suivis pour hépatites virales. Matériel et méthode: Il s'agissait d'une étude observationnelle de type rétrospectif sur la période du 1er Janvier 2010 au 31 Décembre 2016. Résultats : Sur 440 patients suivis pour hépatite virale B (HVB) et/ou C (HVC), 339 avaient des don-nées échographiques exploitables. La prévalence de la SH était de 10,6%.Il n'y avait pas de diffé-rence significative entre les porteurs de l'HVB (10.2%) et ceux de l'HVC (11.6%), p=0,69. Le diabète (20%), l'hypertension artérielle (18,7%), et les patients ne consommant pas d'alcool (12,4%), sem-blaient plus atteints par la SH mais de façon non significative. La SH était associée à l'obésité(OR=7,36 [2,89-18,73], p<0,001), et au sexe féminin (OR= 2,56 [1,27-5,16], p= 0,008). Conclusion: L'obésité et le sexe féminin représentaient les facteurs de risque trouvés pour la SHdans cette étude

ABSTRACT

Objective To understand the prevalence and metabolic abnormalities of fatty liver disease among adults in Mianyang City,Sichuan Province,and to analyze their influencing factors.Methods Totally 294 603 adults aged 18 years and older were enrolled by using a multi-stage stratified random sampling method in Mianyang City from November 1,2014 to September 30,2015.Fatty liver was diagnosed by abdominal ultrasound.The general demographic characteristics,smoking history,drinking history,and history of chronic disease were collected through questionnaires.Meanwhile,10 217 subjects were randomly selected for biochemical tests[fasting plasma gluose(FPG),triacylglycerol(TG),total cholesterol(TC),and alanine aminotransferase(ALT)].Results Of these 294 603 subjects,17 105(5.81%)had fatty liver.After having been age-adjusted based on the results of the sixth national census in 2010,the standardized prevalence was 5.32%.The prevalence was significantly higher in males(6.76%;standardized prevalence:7.24%)than in females(5.09%;standardized prevalence:4.08%)(=365.814,<0.001)。The prevalence of fatty liver disease was significantly higher in people with current smokers(8.52%)/ex-smokers(8.89%),occasional alcohol users(6.79%)/regular alcohol users(10.51%)/daily alcohol users(10.62%),and patients with hypertension(12.14%)/diabetes(15.19%)/coronary heart disease(10.22%)than those without corresponding characteristics(all <0.001).Abnormal increase in body mass index,diastolic blood pressure,FPG,TG,TC,and ALT were risk factors for fatty liver in Logistic regression model.Conclusions The prevalence of fatty liver in adults is relatively low in Mianyang City.Patients with fatty liver usually have varying degrees of abnormal increase in blood lipids,blood glucose,blood pressure,and ALT.Healthy lifestyles and comprehensively assessment of metabolic status are conducive to the prevention and treatment of fatty liver and extrahepatic complications.
