The gut and the liver are the key organs in nutrient absorption and metabolism. Bile acids, drugs, and toxins undergo extensive enterohepatic circulation. Bile acids play a major role in several hepatic and intestinal diseases. Endotoxins deriving from intestinal Gram-negative bacteria are important in the pathogenesis of liver and systemic diseases. Chronic liver diseases can influence gastrointestinal motility, which together with other factors may contribute to bacterial overgrowth and in patients with ascites to an increased risk of spontaneous bacterial peritonitis. Patients with end-stage liver disease frequently develop portal hypertension leading to varices, gastric vascular ectasia, and portal hypertensive gastroenteropathy. Several liver and biliary abnormalities are observed in patients with inflammatory bowel disease (primary sclerosing cholangitis, autoimmune hepatitis, cholelithiasis). The primary defect in hemochromatosis is located in the intestine, causing an inappropriate increase in iron absorption, and the liver is the site of earliest and heaviest iron deposition. Elevated transaminases are observed in many patients with celiac disease, and steatohepatitis frequently develops in patients with jejunoileal bypass and short bowel syndrome. Furthermore, the liver is the primary organ for metastasis of intestinal cancer. Many viral, bacterial, fungal, and parasitic diseases affect the intestine as well as the liver and the biliary tract.

We investigated, in a well-established canine model of human sepsis, the effects of two different techniques of sympathetic blockade during bacterial peritonitis on pain relief, hemodynamics, and survival rate. Twenty-two purpose-bred beagles (12-28 months old, weighing 10-12 kg) were studied. Fourteen animals received an epidural infusion of bupivicaine and morphine, and the other eight received either a celiac plexus block (n = 4) or a sham block (n = 4). Eighteen of the 22 animals received an intraperitoneal challenge of Escherichia coli (1-10 x 10(9) CFU kg(-1) body weight). At comparable doses of intraperitoneal-implanted E. coli (2.5-5 x 10(9) CFU kg(-1) body weight), the addition of sympathetic blockade produced a synergistic decrease in survival times (P = 0.002) and mean left ventricular ejection fraction (P = 0.008), and increase in creatinine levels (P = 0.02). There was also a significant increase in tumor necrosis factor (TNF) levels (P = 0.004) and decrease in blood endotoxin clearance (P = 0.006) associated with sympathetic blockade during sepsis. The celiac plexus-blocked animals had no improvement in pain scores, and subjectively looked clinically worse than animals with sepsis without a celiac plexus block. In contrast, the epidural block was effective in blocking the pain and discomfort associated with low lethality doses of intraperitoneal bacteria reflected by no increase in pain scores compared with animals not receiving bacterial challenge. This study shows that during severe bacterial peritonitis, maintenance of sympathetic tone irrespective of pain relief provided is necessary for clearance of bacterial toxins, control of proinflammatory mediator release, hemodynamic stability, and survival.

Background & aims Celiac disease (CD) is a multisystem disorder triggered by dietary gluten in genetically predisposed individuals that may affect any organ system, including the liver. We evaluated a change in patient model for end-stage liver disease (MELD)-Na and albumin level from the time of celiac disease diagnosis to six months later, after implementing a gluten-free diet. Methods A retrospective study was conducted from January 1, 2006, to June 30, 2018. CD was diagnosed based on celiac antibodies and/or histopathological data. MELD-Na and albumin were calculated at the start of the gluten-free diet and six months later. Additional variables like gender, ethnicity, serum IgA level, serum IgG level, human leukocyte antigen (HLA) type, and markers of end-stage liver disease were collected. Descriptive statistics, including means, were reported with the standard deviation for the continuous variables along with frequencies and percentages for all categorical variables. Results A total of 18 patients (55.6% male) were identified as having both cirrhosis and CD. The mean age at the time of celiac diagnosis was 53.6, and 94.4% were Caucasian. CD was diagnosed using celiac antibodies (100%) and histopathological data (44.4%). Most common celiac antibodies include anti-tissue transglutaminase antibodies (77.8%). End-stage liver disease markers like abdominal ascites (55.6%), variceal bleed (50.0%), acute or chronic kidney injury (16.7%), hepatocellular carcinoma (HCC) (11.1%), hepatic encephalopathy (HE) (50.0%), spontaneous bacterial peritonitis (SBP) (5.6%), and liver transplant (0.0%) were seen. The mean baseline MELD-Na score was 11.8, and albumin was 3.5 at the time of celiac diagnosis and mean MELD-Na was 11.8, and albumin was 3.5 six months after a gluten-free diet. Conclusion It is difficult to conclude any exact relationship between change in MELD-Na score after gluten-free diet, but an improving trend is noted in patients with higher MELD-Na score such as 17 or higher. There is no change or worsening of MELD-Na score in patients with lower MELD-Na score. There was no change in mean MELD-Na and albumin level after gluten-free diet.
