G-protein coupled receptor 120 (GPR120) is a G-protein-coupled receptor whose endogenous ligands have been identified as long-chain fatty acids. Recently, it has been shown that GPR120 expression in human adipose tissue is higher in obese than in lean individuals. Interestingly, a GPR120 deficient mouse model presents an unfavorable phenotype when fed a high-fat diet with obesity, glucose intolerance and fatty liver, characteristics also found in type 2 diabetes (T2D). M...
OBJECTIVES: I. Determine the effectiveness of oral bile acid therapy with cholic acid, chenodeoxycholic acid, and ursodeoxycholic acid in patients with peroxisomal disorders involving impaired primary bile acid synthesis. II. Determine whether suppression of synthesis of atypical bile acids and enrichment of bile acid pool with this regimen is effective in treating this patient population and improving quality of life.
The purpose of this study is to determine whether the bile acid circulation is changed after gastric bypass surgery. Further, to account for how the changed anatomy of the gut influences how the bile acid and food is mixed in the gut and how this is associated with the changes in gut hormone release after the surgery. Our hypothesis is that bile acid reabsorption from the gut is increased as animal models suggest so and bile acid blood concentration increases after surgery.
Agonistic activation of fat metabolite responsive G-protein-coupled receptors (GPCR) has been linked to improved glucose metabolism through increased glucose-stimulated-insulin-secreting (GSIS) and incretin release, improved insulin sensitivity and reduced low grade inflammation. In vitro studies have demonstrated that pinolenic acid (20% of pine nut oil) is a potent dual agonist of two GPCRs: free fatty acid receptor-1 (FFA1, formerly GPR40) and free fatty acid receptor-4 (FFA...
The purpose of this study is to evaluate the effect of bariatric surgery in bile acid homeostasis and its interrelationship with the metabolic changes induced by the surgery. This study contemplates the following hypothesis: - Bariatric Surgery induce a new study state in bile acid homeostasis with higher bile acid synthesis in association with increased bile acid content. - The major effects of bariatric surgery on bile acid synthesis and is observed one month ...
The primary purpose of the study is to evaluate the therapeutic efficacy and safety of cholic acid in subjects with identified inborn errors of bile acid synthesis.
The purpose of this study is to examine the efffects of bile acid and bile acids sequestrants on GLP-1 secretion, in patients after Roux-en-Y gastric bypass.
This study aims to identify the safety and tolerability of bile acid supplementation in patients with progressive Multiple Sclerosis (MS). Participants will also be assessed for an impact of the bile acid on their immune system and gut microbiome. Half of the participants will receive the bile acid tauroursodeoxycholic acid (TUDCA) and half will receive placebo. The investigators believe participants who take TUDCA will have normalization of blood bile acid levels, a normalizat...
Many patients suffer from chronic diarrhoea after surgical treatment for cancer in the right side of the colon. The investigators' main hypothesis is that colon cancer patients with chronic diarrhoea have a higher risk of bile acid malabsorption compared with colon cancer patients without diarrhoea. The investigators also expect that a part of the cases of bile acid malabsorption is caused by underlying bacterial overgrowth in the small bowel. The investigators a...
The purpose of this study is to determine whether LJN452 improves the symptoms of bile acid diarrhea and to assess its safety and tolerability profile in patients with primary bile acid diarrhea (pBAD) to guide decision-making regarding further clinical development in this indication.
The purpose of this study is to examine the effects of bile acid and bile acids sequestrants on GLP-1 Secretion, during a meal, in patients after Roux-en-Y gastric bypass.
The purpose of this study is to evaluate the impact of different ligands of GPR 119 (a G protein-coupled receptor in the intestine) on the secretion of the incretin hormones, GLP-1 and GIP.
OBJECTIVES: I. To Evaluate the therapeutic efficacy of cholic acid during provision of compassionate treatment to patients with identified inborn errors of bile acid synthesis and metabolism II. To assess the safety and tolerability of cholic acid
It is unknown whether the bile acid pathway is altered in obesity. This study is designed to compare obesity and health to determine if the bile acid pathway differs depending on health state.
Bile acid malabsorption (BAM), a common cause of diarrhoea, affects 1 million people in the UK, but is often misdiagnosed as irritable bowel syndrome or goes unrecognised in patients with inflammatory bowel disease. The SeHCAT (seleno-tauro-homocholic acid) test is currently the only diagnostic test for BAM, but it is not widely available and it is also time consuming, expensive and involves exposure to radioactivity. Some clinicians give a course of blind or empirical treatme...
To assess the bile acid composition of cystic bile and serum pharmaco¬kinetics after a 3-week treatment with UDCA and to correlate pharmacokinetic parameters of UDCA in bile and serum during steady state.
The investigational drug, Obeticholic Acid (OCA) is a modified bile acid. Bile acids are used by the body to help with digestion. It is hypothesized that regular treatment with OCA will improve liver function in persons with Primary Biliary Cirrhosis (PBC).
In this study, investigators will investigate the microbiota of bile in common bile duct stone participants. Three key questions are of concern. The first one is whether there is bacteriria in bile in participants without common bile duct stone. The second one is whether the microbiota of bile is similar with that of gut mucosa in common bile duct stone participants. The third one is whether the bacteria in bile of common bile participants with intact papillar is the same as th...
The expression of transporters involved in bile acid homeostasis is differentially regulated during obstructive cholestasis. Bile acids are also substrates of the drug efflux transporter breast cancer resistance protein (BCRP) that is highly expressed in the human intestine. Therefore we intend to analyze whether intestinal BCRP expression could be altered during cholestasis.
Comparing the effect of Liraglutide on bile acid malabsorption, with colesevelam
This project will compare the amount of bile acids and their kinetics in overweight and obese people with normal glucose metabolism, impaired glucose tolerance and frank type 2 diabetes. We hypothesize that bile acids will behave differently in these groups. We will also explore the effects of Colesevelam HCl, a medicine that lowers LDL cholesterol by binding bile acids, on bile acids in those groups. We hypothesize the drug may have different actions on bile acids in subjec...
Increasing rates of highly malignant hepatocellular carcinoma (HCC) and biliary tract cancers (GBTC) observed in Western populations may be related to obesogenic lifestyle factors and their metabolic consequences, such as metabolic syndrome (MetS), inflammation and altered production of bile acids (BA). Such lifestyle behaviours may induce changes in the gut microflora which in turn affect BA profiles, increasing their carcinogenicity. Some elevated BA may be oncogenic in expos...
The purpose of this study is to determine how people with high triglycerides metabolize and absorb bile acids, compounds made in the body from cholesterol. This project has two objectives: A) To define the mechanism of impaired bile acid absorption in hypertriglyceridemia (specifically we will determine if the active or passive component of absorption is abnormal) and B) to determine the contribution of an alternative pathway of bile acid synthesis which begins with 27-hydro...
Accumulating evidence suggests that bile acids in our intestines may constitute essential components in the complex mechanisms regulating gut hormone secretion and glucose homeostasis. Thus, it is likely that modification of the enterohepatic circulation of bile acids can lead to changes in gut hormone secretion and consequently affect glucose homeostasis. The current study is a human interventional randomized controlled cross-over study including four study days for eac...
OCAPUSH (EudraCT 2014-002313-33) is a double-blind placebo-controlled parallel-arms study of the effects of obeticholic acid on farnesoid X receptor expression in jejunum and on gut microbiota in morbidly obese patients and healthy volunteers. Obeticholic acid (OCA, 6-ethyl-chenodeoxycholic acid, INT-747) is a semi-synthetic derivative of the major human bile acid chenodeoxycholic acid and will be administered orally at a dose of 25 mg/day during three weeks to 20 morbidly obes...
