Excessive alcohol consumption leads to severe alcoholic hepatitis (sAH) or chronic alcoholic pancreatitis (CAP) only in a subset of patients. We aimed to characterize the intestinal microbiota profiles of alcoholic patients according to the presence and nature of the complications observed: sAH or CAP. Eighty two alcoholic patients were included according to their complications: CAP (N = 24), sAH (N = 13) or no complications (alcoholic controls, AC, N = 45). We analyzed the intestinal microbiota by high-throughput sequencing...

Previous studies have reported that alcohol dehydrogenase (ADH) isoenzymes possess diagnostic value in gastric cancer (GC). However, the prognostic value of ADH isoenzymes in GC remains unclear. The aim of the present study was to identify the prognostic value of ADH genes in patients with GC. The prognostic value of ADH genes was investigated in patients with GC using the Kaplan-Meier plotter tool. Kaplan-Meier plots were used to assess the difference between groups of patients with GC with different prognoses...

Obesity is the pandemic of the 21st century. Obesity comorbidities, including hypertension, dyslipidaemia and glucose intolerance define metabolic syndrome, which increases mortality risk and decreases the quality of life. Compared with lifestyles (diet and physical activity) and pharmacological interventions, bariatric surgery is by far the most effective treatment for obesity and its comorbidities. This minimally invasive surgical treatment is based on an increase of satiety (by hormonal regulation and decreasing stomach volume) or a decrease in nutrient retention (gastric and/or intestinal resection)...

PURPOSE: Chronic pancreatitis (CP) can cause fat or bile acid malabsorption due to exocrine insufficiency. Fat or bile acid malabsorption has been reported to increase the risk of urolithiasis through increased intestinal oxalate absorption. However, no studies have reported an association between CP and urolithiasis. METHODS: We identified 15,848 patients (age: ≥20 years) diagnosed as having CP between 2000 and 2010 from the National Health Insurance Research Database as the study cohort...

Alcohol use disorder (AUD) results in increased intestinal permeability, nutrient malabsorption, and increased risk of colorectal cancer (CRC). Our understanding of the mechanisms underlying these morbidities remains limited because studies to date have relied almost exclusively on short-term heavy/binge drinking rodent models and colonic biopsies/fecal samples collected from AUD subjects with alcoholic liver disease (ALD). Consequently, the dose- and site-dependent impact of chronic alcohol consumption in the absence of overt liver disease remains poorly understood...

Ectopic varices are dilated portosystemic venous collaterals located outside of the gastro-esophageal region. Whereas they are common endoscopic findings in patients with portal hypertension, ectopic variceal bleeding is rather rare and accounts for only 1 to 5 % of all variceal bleedings. The rectum and the duodenum are the most common sites for ectopic varices, but they can be present along the whole intestinal tract and neighborhood. At present, there is no consensus well established on diagnostic workup for ectopic variceal bleeding and their therapeutic strategies...

BACKGROUND: Small intestinal bacterial overgrowth (SIBO) is a condition characterised by symptoms similar to pancreatic exocrine insufficiency (PEI) in chronic pancreatitis patients. SIBO is thought to complicate chronic pancreatitis in up to 92% of cases; however, studies are heterogeneous and protocols non-standardised. SIBO may be determined by measuring lung air-expiration of either hydrogen or methane which are by-products of small bowel bacterial fermentation of intraluminal substrates such as carbohydrates...

Oral administration of insulin increases patient comfort and could improve glycemic control thanks to the hepatic first passage. However, challenges remain. The current approach uses poly (D, lactic-co-glycolic) acid (PLGA) nanoparticles (NPs), an effective drug carrier system with a long acting profile. However, this system presents a bioavailability of less than 20% for insulin encapsulation. In this context, physico-chemical parameters like surface charge could play a critical role in NP uptake by the intestinal barrier...

MetS syndrome (MetS) is a term used to characterize individuals having at least three of the following diseases: obesity, dyslipidemia, hyperglycemia, insulin resistance, hypertension, and non-alcoholic fatty liver disease (NAFLD).  It is widespread and the number of individuals with MetS is increasing.  However, the events leading to the manifestation of MetS are not well understood.  Here, we show that loss of mARV1 in mice results in resistance to acquiring diseases associated with MetS.   Arv1-/- animals fed a high fat diet were resistant to diet-induced obesity, had lower blood cholesterol and triglycerides levels, and retained glucose tolerance and insulin sensitivity...

Depression and liver disease are closely associated. Every third patient with liver cirrhosis or hepatitis shows depressive symptoms. On the other hand, every third patient with depressive disorder develops an alcohol disorder at some point during his / her life. A crucial link between depression and hepatic disease seems to be inflammatory processes in which the microbiome and increased intestinal permeability of the intestine play a pivotal role. Depression as well as liver disease, alcohol consumption, stress, and aging processes disturb the delicate balance of intestinal microbiota resulting in increased intestinal permeability...

BACKGROUND: Cigarette smoking is the greatest preventable cause of morbidity and premature mortality in the United States. Approved pharmacological treatments for smoking cessation are marginally effective, underscoring the need for improved pharmacotherapies. A novel approach might use glucagon-like peptide-1 (GLP-1) agonists, which reduce alcohol and drug use in preclinical studies. GLP-1 is produced in the intestinal L-cells and in the hindbrain. The peptide maintains glucose homeostasis and reduces food intake...

BACKGROUND & AIMS: Binge alcohol causes gut leakiness, contributing to increased endotoxemia and inflammatory liver injury, although the molecular mechanisms are still elusive. This study was aimed at investigating the roles of apoptosis of enterocytes and nitration followed by degradation of intestinal tight junction (TJ) and adherent junction (AJ) proteins in binge alcohol-induced gut leakiness. METHODS: The levels of intestinal (ileum) junctional complex proteins, oxidative stress markers and apoptosis-related proteins in rodents, T84 colonic cells and autopsied human ileums were determined by immunoblot, immunoprecipitation, immunofluorescence, and mass-spectral analyses...

Excess alcohol consumption can lead to alcoholic liver disease. Fibroblast growth factor 21 (FGF21) is a metabolic regulator with multiple physiologic functions. Previous study demonstrated that FGF21 deficiency exacerbated alcohol-induced liver injury and exogenous FGF21 administration protected liver from chronic alcohol-induced injury. In this study, we aimed to explore the role of FGF21 in alcohol metabolism in mice. FGF21 knockout (KO) mice and the wild time (WT) control mice were divided into two groups and fasted for 24 h followed by a bonus of alcohol treatment at a dose of 5 g/kg body weight via gavage...

BACKGROUND: The association of alcohol intake with the incidence of Barrett's esophagus (BE) has been inconsistent. Although hiatal hernia and male sex are well-known risk factors of BE, its effect on the association of alcohol intake with the incidence of BE remains unknown. AIM: To investigate whether the influence of alcohol intake on the occurrence of BE might differ depending on male sex and presence of hiatal hernia. METHODS: We utilized a database of 8031 patients that underwent upper endoscopy for health screening in a prospective, multicenter, cohort study (the Upper Gastro Intestinal Disease study)...

Cytochromes are expressed in many different tissues of the human body. They are found mostly in intestinal and hepatic tissues. Cytochromes P450 (CYPs) are enzymes that oxidize substances using iron and are able to metabolize a large variety of xenobiotic substances. CYP enzymes are linked to a wide array of reactions including and O-dealkylation, S-oxidation, epoxidation, and hydroxylation. The activity of the typical P450 cytochrome is influenced by a variety of factors, such as genus, environment, disease state, herbicide, alcohol, and herbal medications...

Adverse fluctuations in the distribution of the intestinal microbiome cohort has been associated with the onset of intra- and extra-intestinal inflammatory conditions, like the metabolic syndrome (MetS) and it's hepatic manifestation, non-alcoholic fatty liver disease (NAFLD). The intestinal microbial community of obese compared to lean subjects has been shown to undergo configurational shifts in various genera, including but not limited to increased abundances of Prevotella, Escherichia, Peptoniphilus , and Parabacteroides and decreased levels of Bifidobacteria, Roseburia , and Eubacteria genera...

BACKGROUND: At a group level, hangover severity during the day has been described to follow an inverted U-shaped curve, with gradually increasing severity scores that, after reaching a peak, gradually decrease towards zero. The aim of the current study was to examine if and how individual drinkers' hangover severity scores vary during the day. METHODS: Data from a survey (Penning et al. 2012) in which N=732 drinkers reported on their latest alcohol hangover were re-analysed...
