Non-alcoholic fatty liver disease (NAFLD) is a crucial health problem with a prevalence that is increasing concurrently with the obesity epidemic on a global scale. Steatosis, nonalcoholic steatohepatitis (NASH), hepatocellular carcinoma (HCC), cirrhosis, and advanced fibrosis constitute the disease spectrum covered by NAFLD. NASH-related cirrhosis and HCC is currently the second most common indication for liver transplantation. Although lifestyle modifications, especially weight loss, effectively reduces the liver injury in NASH, adherence in the clinical setting is low. Potential treatments for NASH are still under investigation in phase 2–3 studies. Bariatric surgery can improve metabolic components and cause great weight loss. Therefore, bariatric surgery may reverse the pathological liver changes in NAFLD and NASH patients. However, complications such as liver failure after bariatric surgery can occur. This chapter will give an overview of the benefits and pitfalls of bariatric surgery in patients with NAFLD, liver transplant candidates and post-liver transplant patients.

AbstractSignificant weight loss can modify the progression of Nonalcoholic fatty liver disease (NAFLD) with the most convincing evidence coming from bariatric surgery cohorts. Effective ways to non-invasively characterise NAFLD in these patients has been lacking, with high Fibroscan failure rates reported. We prospectively evaluated the utility of Fibroscan using XL-probe over a two-year period. 190 consecutive patients undergoing bariatric surgery were followed as part of their routine care. All patients had Fibroscan performed on the day of surgery and at follow-up a mean of 13 months (± 6.3) later. The majority of patients were female (82%) with mean age of 42. Fibroscan was successful in 167 (88%) at baseline and 100% at follow up. Patients with a failed Fibroscan had higher body mass index (BMI) and alanine transaminase (ALT), but no difference in FIB-4/NAFLD score. Mean baseline Liver stiffness measurement was 5.1 kPa, with 87% of patients classified as no fibrosis and 4% as advanced fibrosis. Mean baseline controlled attenuation parameter was 291, with 78% having significant steatosis, 56% of which was moderate-severe. Significant fibrosis was associated with higher BMI and HbA1c. Significant steatosis was associated with higher BMI, ALT, triglycerides and insulin resistance. Mean follow up time was 12 months with weight loss of 25.7% and BMI reduction of 10.4 kg/m2. Seventy patients had repeat fibroscan with reductions in steatosis seen in 90% and fibrosis in 67%. Sixty-four percent had complete resolution of steatosis. Fibroscan can be performed reliably in bariatric cohorts and is useful at baseline and follow-up. Significant steatosis, but not fibrosis was seen in this cohort with substantial improvements post-surgery.

AbstractThe obesity epidemic is a growing public health concern that has a severe effect on the health care system with significant morbidity, mortality, and cost. Treatment options for obesity include lifestyle modifications, pharmacotherapy, and bariatric surgery. Newer, less-invasive therapies including endoscopic bariatric procedures have been developed in recent years to fill the treatment gap that exists between noninvasive approaches and surgery. Bariatric artery embolization (BAE) is a novel minimally invasive endovascular procedure that has been developed to treat obesity. Recent evidence has suggested that bariatric embolization is well tolerated and can induce clinically significant weight loss through a hormonally mediated mechanism. This article will review existing preclinical and clinical data, and explore future directions of the endovascular treatment of obesity.

AbstractBackgroundIn the United States, 18.5% of children are obese. Dietary and lifestyle modifications are key, but often ineffective. There are limited approved pediatric pharmacotherapies. The objective of this study was to evaluate current treatment practices for pediatric obesity among members of the Pediatric Endocrine Society (PES, n = 1300) and the Pediatric Obesity Weight Evaluation Registry (POWER, n = 42) consortium.MethodsA 10-question online survey on treatment of children with obesity in clinical practice was conducted.ResultsThe response rates were 19% for PES and 20% for POWER members. The majority were female (65%) and board certified in pediatric endocrinology (81%). Most practitioners saw 5–10 patients with obesity/week and 19% prescribed weight-loss medications. POWER participants were more likely to prescribe weight-loss medications than PES participants (46% vs. 18%, p =  0.02). Metformin was the most commonly prescribed medication. Response to medication was poor. Use of dietary non-pharmacological treatment options was uncommon. Over half of the respondents (56%) referred patients for bariatric surgery and 53% had local access to pediatric bariatric surgery.ConclusionsMetformin was the most common drug prescribed among respondents, but successful weight-loss responses were uncommon. Among practitioners who are using pharmacological interventions, therapeutic strategies vary widely. Targeted research in pharmacologic and surgical treatment for pediatric obesity is urgently needed.

Reduce Life Expectancy

The obesity epidemic, mainly due to lifestyle changes in recent decades, leads to serious comorbidities that reduce life expectancy. This situation is affecting the health policies of many nations around the world. Traditional measures such as diet, physical activity, and drugs are often not enough to achieve weight loss goals and to maintain the results over time. Bariatric surgery (BS) includes various techniques, which favor rapid and sustained weight loss. BS is a useful and, in most cases, the best treatment in severe and complicated obesity. In addition, it has a greater benefit/risk ratio than non-surgical traditional therapies. BS can allow the obese patient to lose weight quickly compared with traditional lifestyle changes, and with a greater probability of maintaining the results. Moreover, BS promotes improvements in metabolic parameters, even diabetes remission, and in the quality of life. These changes can lead to an increase of life expectancy by over 6 years on average. The nutrition of people before and after BS must be the subject of indications from a trained staff, and patients must be followed in the subsequent years to reduce the risk of malnutrition and the associated problems. In particular, it is still debated whether it is necessary to lose weight prior to surgery, a procedure that can facilitate the surgeon’s work reducing the surgical risk, but at the same time, lengthens preparation times increasing the risks associated with concomitant pathologies. Furthermore, preventing nutritional deficiencies prior to the intervention can improve the results and reduce short- and long-term mortality.

Alcoholic Fatty Liver Disease

Introduction; p to 300 million people have the body mass index (BMI) greater than 30 kg/m2. Obesity is the cause of many serious diseases, such as type 2 diabetes, hypertension, and non-alcoholic fatty liver disease (NAFLD). Bariatric surgery is the only effective method of achieving weight loss in patients with morbid obesity. Objectives: The aim of the study was to assess the impact of bariatric surgery on non-alcoholic fatty liver disease in patients operated on due to morbid obesity. Material and Methods: We included 20 patients who were qualified for bariatric procedures based on BMI > 40 kg/ m2 or BMI > 35kg/m2 with the presence of comorbidities. The average body weight in the group was 143.85kg, with an average BMI of 49.16kg/m2. Before the procedure, we evaluated the severity of non-alcoholic fatty liver disease in each patient using the Sheriff-Saadeh ultrasound scale. We also evaluated the levels of liver enzymes. Follow-up evaluation was performed twelve months after surgery. Results: Twelve months after surgery, the average weight was 102.34 kg. The mean %WL was 33.01%, %EWL was 58.8%, and %EBMIL was 61.37%. All patients showed remission of fatty liver disease. Liver damage, evaluated with ultrasound imaging, decreased from an average of 1.85 on the Sheriff-Saadeh scale, before surgery, to 0.15 twelve months after surgery (p < 0.001). As regards liver enzymes, the level of alanine aminotransferase decreased from 64.5 (U/l) to 27.95 (U/l) (p < 0.001), and the level of aspartate aminotransferase decreased from 54.4 (U/l) to 27.2 (U/l). Conclusions: Bariatric procedures not only lead to a significant and lasting weight loss, but they also contribute to the reduction of fatty liver disease and improve liver function.
