By means of consecutive pancreatic stimulation, we have investigated the presence of changes of pancreatic function in alcoholic patients, with and without alcoholic liver disease, in order to detect functional alterations and possible association of hepatic and pancreatic disease. The patients were 49 chronic alcoholics (8 patients without liver disease, 11 hepatic steatosis, 9 alcoholic hepatitis and 21 alcoholic cirrhosis) and 15 non alcoholic subjects (8 normal controls and 7 cases of non alcoholic cirrhosis). In all the cases two consecutive stimulations were carried out: first with secretin and cholecystokinin (CCK) and second with CCK alone. The total volume and concentration as well as the output of bicarbonate, trypsin, amylase and total proteins were measured in the duodenal juice. Patients with alcoholic cirrhosis had larger volumes of duodenal juice and lower concentrations of bicarbonate, enzymes and proteins. There was also a tendency to larger volume and lower bicarbonate concentration as the hepatic lesion was more severe. Bicarbonate output was significatively higher in patients with alcoholic cirrhosis but for the remaining parameters the outputs were similar in all the groups. In conclusion, the alterations in pancreatic function parallel the severity of the liver disease. None of the patients had changes consistent with chronic pancreatitis.

Carbonic anhydrases are a family of enzymes that catalyze the reversible condensation of water and carbon dioxide to carbonic acid, which spontaneously dissociates to bicarbonate. Carbonic anhydrase III (Car3) is nutritionally regulated at both the mRNA and protein level. It is highly enriched in tissues that synthesize and/or store fat: liver, white adipose tissue, brown adipose tissue, and skeletal muscle. Previous characterization of Car3 knockout mice focused on mice fed standard diets, not high-fat diets that significantly alter the tissues that highly express Car3. We observed lower protein levels of Car3 in high-fat diet fed mice treated with niclosamide, a drug published to improve fatty liver symptoms in mice. However, it is unknown if Car3 is simply a biomarker reflecting lipid accumulation or whether it has a functional role in regulating lipid metabolism. We focused our in vitro studies toward metabolic pathways that require bicarbonate. To further determine the role of Car3 in metabolism, we measured de novo fatty acid synthesis with in vitro radiolabeled experiments and examined metabolic biomarkers in Car3 knockout and wild type mice fed high-fat diet. Specifically, we analyzed body weight, body composition, metabolic rate, insulin resistance, serum and tissue triglycerides. Our results indicate that Car3 is not required for de novo lipogenesis, and Car3 knockout mice fed high-fat diet do not have significant differences in responses to various diets to wild type mice.

New evidence suggests that low serum Vitamin D may cause nonalcoholic fatty liver disease (NAFLD). Hypovitaminosis D is associated with the severity and incidence of NAFLD. The objective of this study was to conduct a systematic review on randomized controlled trials (RCTs) assessing the effect of Vitamin D on serum metabolic profile among NAFLD patients. Databases including PubMed, Institute for Scientific Information Web of Science, Scopus, and Google Scholar were searched up to November 2016. RCTs which studied Vitamin D effect on metabolic profiles and liver function, and conducted among adults were included. Six articles were eligible to be considered in this systematic review. According to the result, Vitamin D supplementation might improve lipid profile and inflammatory mediators when compared with placebo. No article indicated significant effect of Vitamin D on liver enzymes except one article which revealed that Vitamin D together with calcium carbonate can reduce liver enzymes. Vitamin D supplementation may not improve anthropometric measures and glycemic index variables among patients with NAFLD. Vitamin D supplement might improve NAFLD symptoms, especially inflammatory mediators. More RCTs in different parts of world with different forms and doses of Vitamin D are necessary.

The role of non-alcoholic fatty liver disease (NAFLD) as a potential independent cardiovascular disease (CVD) risk factor has recently gained considerable attention because CVD is the common cause of death in NAFLD patients. We aimed to estimate the effects of vitamin D supplementation alone or in combination with calcium on atherogenic indices, liver function tests, and grade of disease in patients with NAFLD. One-hundred twenty NAFLD patients were randomized in a double-blind, placebo-controlled clinical trial as follows: D (1000 IU vitamin D), CaD (500 mg as calcium carbonate plus 1000 IU vitamin D) or P (placebo), once daily with meals over 12 weeks. Adjusted for all the baseline measures, reduction in serum ALT, AST, LDL-C/HDL-C, TC/HDL-C, and non-HDL-C were significantly higher in the CaD compared with the P group (p < 0.001, p = 0.03, p < 0.001, p < 0.001, p < 0.001 and p < 0.001, respectively). Also, mean difference of serum ALT, LDL-C/HDL-C, TC/HDL-C, and TG/HDL-C were significantly higher in the CaD than D group (p < 0.001, p = 0.006, p < 0.001 and p = 0.03, respectively). Serum non-HDL-C was marginally decreased in the CaD compared with the D group (p = 0.06). With considering the BMI changes as covariate, reduction in the grade of fatty liver was significantly higher in the CaD and D groups than the P (p < 0.001). The present study suggests that supplemental calcium combined with vitamin D, but not vitamin D alone, may reduce serum atherogenic indices, liver function tests, and grade of disease in patients with NAFLD.
