Intestinal failure (IF) represents a wider spectrum of diseases where intestinal homeostasis has been disrupted.Abstract: CONCLUSION: Our finding supports the importance of NOD2 in the maintenance of intestinal immune homeostasis and may be important to a variety of intestinal stressors. 2012 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.Abstract: METHODS: One hundred ninety-two consecutive patients with IF and 103 healthy controls were genotyped for the three most common NOD2 polymorphisms. Genotypes were compared between the groups and were related to the entities causing IF.Abstract: RESULTS: A high percentage (26%) of patients had at least one of the three most common NOD2 polymorphisms, while only a 4.8% of healthy controls had a mutant genotype. In patients with IF, specific mutations for the 702W, 908R and 1007fs alleles were 11, 5 and 12.5%, respectively, compared with 0.9% (P=0.0003), 1.9% (P=0.1) and 1.9% (P=0.001) in the control group. If we consider patients with any cause of IF other than CD, the percentage is still as high as 18.8%, with specific mutation frequencies of 7.6% (702W; P=0.01), 5.8% (908R; P=0.1) and 8.2% (1007fs; P=0.002). We could not establish an association between a NOD2 mutant genotype with any other specific clinical condition other than CD.
