Abstract
- OBJECTIVES:Hispanics are the fastest growing minority in the United States, yet few studies have examined the phenotypes of inflammatory bowel disease (IBD) in this population. No studies compare IBD presentation between foreign and US-born Hispanics. Our aim was to compare phenotypic characteristics of IBD between Hispanics and non-Hispanic Whites (NHWs), as well as between US-born and foreign-born Hispanics.METHODS:We retrospectively identified cohorts of adult IBD patients from 1998 to 2009 and compared ethnic variation in phenotype, including disease type (Crohn's disease or ulcerative colitis (UC)), extra-intestinal manifestations (EIMs), Montreal classification, surgeries, hospitalizations, and medication prescription.RESULTS:A total of 325 patients were included; 208 were Hispanics. Foreign-born Hispanics, accounting for 68% of the total, were diagnosed at an older age than US-born Hispanics and NHWs (45 vs. 25 and 27, respectively, P<0.05). Foreign-born Hispanics manifested more UC than US-born Hispanics or NHWs (59.9% vs. 41% and 28.2%, respectively, P<0.05). No difference was noted in the prevalence of EIMs between Hispanics and NHWs. More upper gastrointestinal tract Crohn's was observed in NHWs (12.5% vs. 3.9%, P<0.05). The incidence density rate of IBD-related surgeries in NHWs was higher than in Hispanics (22.9 vs. 7.3 surgeries/100 person-years, P<0.01, hazard ratio: 0.3, 95% confidence interval: 0.14-0.5). Hispanic patients had fewer prescriptions for biologics and immunomodulators than NHWs (22.2% vs. 55.6%, P<0.01 and 35.7% vs. 53.8%, P<0.01, respectively).CONCLUSIONS:This study demonstrates differences in IBD presentation among NHW, US-born Hispanic, and foreign-born Hispanic groups. Further investigation to identify environmental and genetic differences between ethnic groups affected by IBD is warranted. [ABSTRACT FROM AUTHOR]
