United European Gastroenterology (UEG) and European Society for Neurogastroenterology and Motility (ESNM) consensus on gastroparesis
Full text linkBACKGROUND: Gastroparesis is a condition characterized by epigastric symptoms and delayed gastric emptying (GE) rate in the absence of any mechanical obstruction. The condition is challenging in clinical practice by the lack of guidance concerning diagnosis and management of gastroparesis. METHODS: A Delphi consensus was undertaken by 40 experts from 19 European countries who conducted a literature summary and voting process on 89 statements. Quality of evidence was evaluated using grading of recommendations assessment, development, and evaluation criteria. Consensus (defined as ≥80% agreement) was reached for 25 statements. RESULTS: The European consensus defined gastroparesis as the presence of symptoms associated with delayed GE in the absence of mechanical obstruction. Nausea and vomiting were identified as cardinal symptoms, with often coexisting postprandial distress syndrome symptoms of dyspepsia. The true epidemiology of gastroparesis is not known in detail, but diabetes, gastric surgery, certain neurological and connective tissue diseases, and the use of certain drugs recognized as risk factors. While the panel agreed that severely impaired gastric motor function is present in these patients, there was no consensus on underlying pathophysiology. The panel agreed that an upper endoscopy and a GE test are required for diagnosis. Only dietary therapy, dopamine-2 antagonists and 5-HT4 receptor agonists were considered appropriate therapies, in addition to nutritional support in case of severe weight loss. No consensus was reached on the use of proton pump inhibitors, other classes of antiemetics or prokinetics, neuromodulators, complimentary, psychological, or more invasive therapies. Finally, there was consensus that gastroparesis adversely impacts on quality of life and healthcare costs and that the long-term prognosis of gastroparesis depends on the cause. CONCLUSIONS AND INFERENCES: A multinational group of European experts summarized the current state of consensus on definition, symptom characteristics, pathophysiology, diagnosis, and management of gastroparesis

DIETARY METHODS USING LACTOBACILLUS PARACASEI SUBSP. PARACASEI F19 AS NAPE-PLD GENE CARRIER FOR PRODUCING ON DEMAND PEA OR OEA AND RELATIVE BIOLOGICAL DIETARY COMPOSITIONS THEREOF
Full text linkMethod enabling to modulate and customize the production of active lipids involved in exerting an antagonistic action to local inflammation and in modulating the mast cell reactivity, comprising the administering to an host the probiotic Lactobacillus paracasei subsp. Paracasei F19, genetically modified with a nucleotide vector comprising a nucleic acid encoding the human N-acyl-phosphatidylethanolamine phospholipase D (NAPE-PLD), in association with lipid substrates and precursors, to influence the enzymatic reactions of said probiotic agent in the host. The method is useful in the treatment of inflammatory bowel disorder and in the treatment of metabolic syndrome and for controlling of obesity
Nicotinamide methylation and hepatic energy reserve: a study by liver perfusion in vitro.
No full textAbstract: Background/Aims: The synthesis of pyridine nucleotides from nicotinamide requires adenosine triphosphate. In man when exogenous nicotinamide is poorly utilized in this synthesis, the excess follows a dissipative metabolic pathway and is excreted in urine as N-methylnicotinamide. In human cirrhosis N-methylnicotinamide serum levels are higher than normal, in basal condition and after nicotinamide oral load, The aim of this study was to verify N-methylnicotinamide production in relation to hepatic content of adenosine triphosphate during in vitro perfusion of rat liver, in normal conditions and after adenosine triphosphate depletion by metabolic stress.
Methods: ''Stress'' was obtained by pre-washing with saline for 15 min before the perfusion with nutritive medium.
Results: The adenosine triphosphate decrease in the stressed liver was 38% after pre-washing with saline and 80% at the end of nutritive perfusion, In control liver the corresponding decreases were 1% after pre-washing with nutritive medium and 65% at the end of perfusion with the same medium, The total nicotinamide adenine dinucleotide decreases were 44% and 56% in the stressed liver, and 19% and 52% in the control liver, The output levels of N-methylnicotinamide at 90 min of rat liver nutritive perfusion were 31.50+/-4.72 nmol/g for normal liver and 66.40+/-13.17 for stressed liver (p<0.001). Liver adenosine triphosphate was inversely related to N-methylnicotinamide production (r=0.93; p<0.001).
Conclusions: These data suggest that nicotinamide methylation may be enhanced when there is hepatic adenosine triphosphate decrease and energy failure induced by hypoxia or metabolic stress, similar to that obtained in vitro by saline washing before perfusion with nutritive medium, This study shows that the evaluation of N-methylnicotinamide production in man (before and after nicotinamide load) might be useful to explore the energy state of diseased live
