Validation of biochemical scores for liver steatosis before and one year after sleeve gastrectomy

Over the past 10 years bariatric surgeons have embraced our role in not only producing sustained and long-term weight loss, but more importantly we have embraced our role in improving metabolic conditions such as Non-Alcoholic Fatty Liver Disease (NAFLD). With obesity increasing worldwide we have seen a concomitant increase in patients with the progression of NAFLD to nonalcoholic steatohepatitis (NASH) and ultimately cirrhosis [1]. Although we have more and more evidence of remission of NAFLD and NASH, liver biopsy remains the gold standard for tracking regression and remission.

Recent studies have identified a genetic variant rs641738 near two genes encoding membrane boundO-acyltransferase domain-containing 7 (MBOAT7) and transmembrane channel-like 4 (TMC4) that associate with increased risk of non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), alcohol-related cirrhosis, and liver fibrosis in those infected with viral hepatitis1-7. Based on hepatic expression quantitative trait loci analysis it has been suggested thatMBOAT7 loss of function promotes liver disease progression1-7, but this has never been formally tested. Here we show thatMboat7 loss, but notTmc4, in mi...

CONCLUSION: Despite some limitations of our study, such as the small number of patients, and the use of two different methods of evaluation (biopsy and elastography), the data obtained allow us to conclude that of the 39 evaluated cases, 33% (13) presented progression of fibrosis and the total group of 50 patients, 42% had cirrhosis or died due to liver disease. The presence of NASH on hepatic biopsy did not prove to be, in our study, a predictive of the evolution of hepatic fibrosis in the patients.RESUMO CONTEXTO: A doen ça hepática gordurosa não alcoólica vem sendo diagnosticada com frequ&eci...

Non-alcoholic fatty liver disease (NAFLD) is a growing challenge to global public health. It is defined as the increased accumulation of hepatic triglyceride (>5%) in the absence of excessive alcohol consumption or other causes of liver disease. The NAFLD spectrum encompasses steatosis (non-alcoholic fatty liver, NAFL) and non-alcoholic steatohepatitis (NASH), an inflammatory form of the condition marked by the presence of hepatocyte damage and progressive fibrosis that may lead to cirrhosis.[1,2] Although NAFLD may occur in patients with normal weight, it is closely associated with the presence of the metabolic syndrom...

Non-alcoholic fatty liver disease (NAFLD) has emerged as one of the leading liver diseases worldwide. NAFLD is characterised by hepatic steatosis and may progress to an inflammatory condition termed non-alcoholic steatohepatitis, (NASH), liver cirrhosis and hepatocellular carcinoma. It became evident in the last years that NAFLD pathophysiology is complex and involves diverse immunological and metabolic pathways. An association between intestinal signals (e.g. derived from the gut microbiota) and the development of obesity and its metabolic consequences such as NAFLD are increasingly recognized. Preclinical studies have sh...

NAFLD—which can develop into liver fibrosis, nonalcoholic steatohepatosis, cirrhosis, and hepatocellular carcinoma—is defined as an excess accumulation of fat caused by abnormal lipid metabolism and excessive reactive oxygen species (ROS) generation in hepatocytes. Recently, we reported that Peroxiredoxin 5 (Prx5) plays an essential role i...

Abstract Non-Alcoholic Fatty Liver Disease (NAFLD), the most common liver disease, is characterized by accumulation of fat (>5% of the liver tissue), in the absence of alcohol abuse or other chronic liver diseases. Its prevalence is increasing because of obesity, metabolic syndrome or Type 2 Diabetes Mellitus (T2DM). NAFLD can cause liver inflammation and progress to Non-Alcoholic Steatohepatitis (NASH), fibrosis, cirrhosis or Hepatocellular Cancer (HCC). Nevertheless, Cardiovascular Disease (CVD) is the most common cause of morbidity and mortality in NAFLD/NASH patients. Current guidelines suggest the use of p...

Fatty liver disease is characterized by a series of pathological conditions ranging from hepatic lipid accumulation (steatosis), to hepatocyte degeneration (ballooning), inflammation (steatohepatitis) and, eventually, cirrhosis and hepatocellular carcinoma [1,2]. Fatty liver disease may be the result of long-term excessive ethanol consumption, (alcoholic liver disease), or of visceral obesity and metabolic syndrome without ethanol consumption, leading to nonalcoholic fatty liver disease (NAFLD) which can evolve to nonalcoholic steatohepatitis (NASH) [3].

The prevalence of non-alcoholic fatty liver disease (NAFLD) has been increasing rapidly and at the forefront of worldwide concern. Characterized by excessive fat accumulation in the liver, NAFLD regularly coexists with metabolic disorders, including type 2 diabetes, obesity, and cardiovascular disease. It has been well established that the presence of NAFLD increases the incidence of type 2 diabetes, while diabetes aggravates NAFLD to more severe forms of steatohepatitis, cirrhosis, and hepatocellular carcinoma. However, recent progress on the genotype/phenotype relationships in NAFLD patients indicates the development of ...
