Comparison of Concordance of Peptic Ulcer Disease, Non-Adenomatous Intestinal Polyp, and Gallstone Disease in Korean Monozygotic and Dizygotic Twins: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph191912708. [PMID: 36232007 PMCID: PMC9566074 DOI: 10.3390/ijerph191912708] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 09/26/2022] [Accepted: 10/01/2022] [Indexed: 06/01/2023]
Abstract
Epidemiological studies have suggested the role of multiple genetic and environmental factors in the development of non-neoplastic gastrointestinal (GI) diseases; however, little information is available on these factors in the Korean population. Therefore, this cross-sectional study explored the effect of these factors by analyzing the concordance of several benign GI disorders in 525 monozygotic twins compared to that in 122 dizygotic twins aged >20 years from the Healthy Twin Study data of the Korean Genome and Epidemiology Study (2005-2014). Chi-square test, Wilcoxon rank-sum, and binomial and multinomial logistic regression models were used for statistical analysis. There was lack of concordance of gastric/duodenal ulcers and cholelithiasis/cholangitis between monozygotic twins compared to that in dizygotic twins, suggesting that environmental factors may mediate those concordant disease expressions in monozygotic twins. The concordance of intestinal polyps in monozygotic twins was 32% lower than that in dizygotic twins (p = 0.028), indicating that the effect of genetic factors on the risk for intestinal polyp development may be low. In conclusion, the lack or low concordance of several benign GI diseases between monozygotic and dizygotic twin groups suggests the relative importance of environmental factors, indicating that these are preventable diseases.

Abstract
BACKGROUND Nasal polyposis is a common disease of which little is currently known. Recent studies have shown up-regulation of several proangiogenic factors. The aim of this study was to assess and quantify how much angiogenesis occurs in nasal polyps and therefore whether angiogenesis is involved in the etiology of polyposis. METHODS Biopsy specimens of polyp tissue and inferior turbinate (IT) were taken from patients undergoing polypectomy and compared with IT samples from control patients. Five patients were used per study group. Biopsy specimens were either stained with a fluorescent lectin for confocal microscopy or snap frozen and sectioned for histology for the examination of multiple measures of angiogenesis. RESULTS No significant differences in capillary density, capillary-associated proliferation, capillary surface density, or capillary volume density were seen between the three study groups, and the regression of surface density versus volume density described a linear relationship. Polyp samples showed increases in capillary diameter and interstitial proliferation. CONCLUSION These results show no active angiogenesis occurring in the polyp or changes in capillary bed architecture, although capillaries seem more edematous in the polyp. As the capillary supply increases in line with the physiological needs of the growing polyp, we conclude that angiogenesis is not a driving force in the etiology of nasal polyposis.
