Diet and Meal Timing in Patients With Non-Alcoholic Fatty Liver Disease: A Pilot Study
Non-Alcoholic Fatty Liver DiseaseThis study will assess the impact of time-restricted eating (8 hours of eating each day) with standard of care lifestyle recommendations (hypocaloric, Mediterranean diet and 30 minutes of exercise on at least 5 days/week) on the degree of fat in the liver as measured by magnetic resonance imaging.
The Availability of the Enhanced Liver Fibrosis (ELF) Test Affects the Rate of Diagnosis of Nonalcoholic...
Fatty LiverNAFLDBackground: During the hepatology evaluation, vibration-controlled transient elastography (VCTE) is often used as a clinical decision aid to target high-risk patients for liver biopsy. The enhanced liver fibrosis (ELF) test is expected to be approved in the US. We tested the hypothesis that making the ELF results available to the treating hepatologist will result in more appropriate and targeted use of liver biopsy in patients with elevated liver enzymes or fatty liver, and will result in more cases of advanced fibrosis/cirrhosis being diagnosed. Methods: During the hepatology evaluation for elevated liver enzymes or fatty liver at the University of Kansas Medical Center, the hepatologists (8 total) make a clinical decision on whether patients shall receive VCTE. At the end of the clinic visit, patients were enrolled and randomized to receiving an ELF test. Patients with liver biopsy within the last five years or decompensated cirrhosis were excluded. The primary outcome is the rate of a diagnosis of F3-4 fibrosis based on liver biopsy or clinical diagnosis of cirrhosis with the initiation of hepatocellular carcinoma surveillance. Four hundred fifty patients are to be enrolled over two years.
Biometabolic Outcomes After Weight Loss Surgery: An Individualized Approach
ObesityMorbid2 moreVariable outcomes after weight loss surgery are likely attributable to complex, poorly understood mechanisms. Due to the significant impact that morbid obesity has on a patient's health, successful management of obesity and its related comorbid medical conditions is important and thus necessitates continued improved therapies for treating obesity. Although the mechanisms of weight loss after surgical intervention are poorly understood, improved understanding of molecular and metabolic changes that occur after weight loss surgery may offer the ability to provide targeted precision therapy for patients with morbid obesity undergoing surgical therapy. In this proposal, the investigators will combine a clinical trial whereby modifications to the gold-standard for weight loss surgery, the gastric bypass, are evaluated while simultaneously measuring molecular and metabolic changes that occur in response to these weight loss procedures. Through creating variable lengths of bypass intestine after gastric bypass, the investigators will be able to determine the effect of malabsorption on clinical outcomes and mechanisms involved in weight loss after gastric bypass. The investigators will also use two control groups. One will be a surgical weight loss control group and consist of patients undergoing a laparoscopic sleeve gastrectomy, a non-intestinal bypass procedure. The other group will consist of patients having non-surgical weight loss therapy. To asses metabolic changes that occur in response to surgical weight therapy and specifically intestinal bypass and malabsorption, the investigators will examine changes in the gut microbiome and plasma gut enteroendocrine hormones. To evaluate molecular pathways that are impacted as a result of gastric bypass and malabsorption, the investigators will measure circulating microRNAs (miRNAs) in the blood. Measurement of miRNAs will provide data on an easily measurable molecular marker for each treatment group. This is a first step in translational exploration of mechanisms of weight loss after surgery by evaluating both clinical and molecular/metabolic outcomes and begin an explorative process towards creating an individualized approach to improving outcomes after weight loss surgery.
Mechanism of Serum PRL in the Development of MAFLD
Type2 DiabetesFatty Liver2 moreMetabolic associated fatty liver disease (MAFLD) has currently reached a worldwide epidemic. Serum PRL levels within or outside physiological range have been found to affect metabolic homeostasis differently. However, the relationship between serum PRL and MAFLD among diabetic patients is unclear. The investigators aimed to explore the association between serum PRL and the risk of MAFLD in patients with type 2 diabetes (T2DM).
The Effect of Vegetarian Diet on Patients With Metabolic Associated Fatty Liver Disease
Metabolism and Nutrition DisorderLiver Diseases3 moreIn this study, 18-60 years old patients with metabolic associated fatty liver disease(MAFLD) will be recruited to test the intervention effect of vegetarian diet. This randomized clinical trial randomized individuals to a healthy vegetarian diet or a healthy omnivorous diet for 24 weeks. At the baseline and after the 24week intervention, the clinical manifestations of MAFLD, obesity levels, indices for glucose and lipid metabolism parameters, results of questionnaire and fecal samples will be collected and analyzed.
NAC- NAFLD And Cushing
Cushing SyndromeFatty Liver DiseaseCushing's Syndrome is a rare disease resulting from prolonged exposure to high levels of circulating cortisol. Clinical manifestations are variable but many patients present a metabolic syndrome (abdominal obesity, insulin resistance, dyslipidemia, hypertension). With regard to the liver, experimental data have shown that excess cortisol leads in an increase in lipogenesis and a reduction in the oxidation of fatty acids. This, in association with an accumulation of visceral adipose tissue and deregulation of adipokines, may contribute to the development of hepatic steatosis in animals. However, few data is available in humans with only one study of 50 patients with Cushing's syndrome estimating the prevalence of hepatic steatosis at 20%. NAFLD (Non-Alcoholic Fatty Liver Disease), is defined as the presence of hepatic steatosis in the absence of secondary causes of intrahepatic fat accumulation. It is a heterogeneous disease ranging from simple liver steatosis, whose prognosis is generally considered to be benign, to inflammation (NASH, Non-Alcoholic Steato-Hepatitis) which may progress to fibrosis, cirrhosis and an increased risk of hepatocellular carcinoma. The prognosis for NAFLD is mainly related to the severity of hepatic fibrosis. In Cushing's syndrome, normalization of cortisol production is the most effective strategy to improve co-morbidities associated with hypercortisolism. However, some of these complications, especially the metabolic co morbidities, could not be completely reversible and no data is available about resolution of hepatic steatosis.
Effect of Canagliflozin on Liver Inflammation Damage in Type 2 Diabetes Patients With Nonalcoholic...
Type 2 Diabetes Mellitus With ComplicationType 2 diabetes mellitus (T2DM) is always accompanied with nonalcoholic fatty liver disease (NAFLD).This prospective study was designed to reveal the potential clinical application and underlying mechanisms of canagliflozin in the treatment of type 2 diabetes combined with nonalcoholic fatty liver disease.
Effect of NNRTI or INSTI on Nonalcoholic Steatosis in HIV/AIDS Patients
Nonalcoholic Fatty Liver DiseaseNonalcoholic Steatohepatitis2 moreIdentifying patients at risk of NAFLD(Nonalcoholic fatty liver disease), especially severe disease with NASH(nonalcoholic steatohepatitis) and fibrosis, is critical. Prevalence of NAFLD in PLWH(People Living With HIV) evaluated by different imaging techniques including US (ultrasonography), elastography, CT(computed tomography ), and magnetic resonance varies from 13% to 58.6% in all published studies. In previous studies, the effect of ART(Anti-Retroviral Therapy) on NAFLD was limited. A cross-sectional analysis found that INSTI(Integrase strand transfer inhibitor) was associated with a higher prevalence of steatosis in AIDS (acquired immunodeficiency syndrome) patients. However, it is not clear whether there is a difference in the degree of nonalcoholic steatosis between AIDS patients receiving NNRTI(non-nucleoside reverse transcriptase inhibitors). Therefore, the investigators plan to conduct a prospective study to assess whether there is any difference in the degree of nonalcoholic steatosis and fibrosis between Chinese HIV(human immunodeficiency virus)/AIDS patients after initial treatment with NNRTI or INSTI, or switching from NNRTI to INSTI.
Predicting Outcomes in Nonalcoholic Steatohepatitis With Advanced Fibrosis
Nonalcoholic SteatohepatitisNonalcoholic Steatohepatitis (NASH) is a condition with increased amount of fat, inflammation and scarring in the liver. In compensated cirrhosis, the liver is coping with this damage and maintaining its important functions. Decompensation occurs when the liver becomes unable to perform all of its functions adequately. Variceal hemorrhage (bleeding from abnormal vessels in the liver called varices), Ascites (abnormal build-up of fluid in the abdomen), and Encephalopathy (brain confusion as a result of the liver not being able to get rid of toxic substances) are three symptoms of liver decompensation. The purpose of this research study is to investigate better ways to routinely monitor the condition of patients with NASH with compensated cirrhosis and to better pinpoint the development of decompensation in the livers of these patients.
Identification and Characterization of NAFLD in Turkey
Non-Alcoholic Fatty Liver DiseaseLiver Diseases3 moreNon-alcoholic fatty liver disease (NAFLD) is with 25% the most prevalent liver disorder in Western society and is associated with overweight, obesity, metabolic syndrome (MetS), type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVD). NAFLD is defined by a hepatic fat accumulation of more than 5% in the absence of classical causes of steatogenesis (e.g. alcohol and steatogenic drugs). It represents a broad spectrum of clinical entities from steatosis to advanced liver disease with hepatic failure. Most of the patients have simple steatosis, however in about 15-30% non-alcoholic steatohepatitis (NASH) develops, which leads to an overall increase in morbidity and mortality due to the progression to fibrosis, cirrhosis and hepatocellular carcinoma (HCC). Patients with NAFLD have no or few, mainly specific symptoms; and generally there is a silent progression of simple steatosis to NASH and in the end liver-related morbidity and mortality. Despite the clinical importance and the potential impact on healthcare resources, the majority of NAFLD patients are currently not detected due to the lack of non-invasive methods to diagnose NAFLD. To date, the prevalance of NAFLD in Turkey among subjects at risk, and its relation to common comorbidities such as obesity, T2DM and CVD is not clear. Therefore, identification of NAFLD patients in this cohort will give information on the prevalence in the group of uncomplicated overweight and obesity and those with concomitant cardiometabolic diseases. By early detecting these patients at risk to develop progressive liver diseases and extrahepatic manifestations, it will be possible to intervene and improve health. Within this context, this study aims to detect prevalence of NAFLD among risk groups. Also, the risk factors related to NAFLD etiology and progression, such as overweight, obesity, T2DM, CVD, diet and physical activity will be studied to have a better understanding of their presumed causal relationship with NAFLD.
