Ethnicity Influences Risk of Inflammatory Bowel Disease (IBD)-Associated Colon Cancer: A Cross-sectional Analysis of Dysplasia Prevalence and Risk Factors in Hispanics and Non-Hispanic Whites With IBD.

ABSTRACT:

Background

Inflammatory bowel disease (IBD) is an emerging disease in Hispanics. In this study, we examine the prevalence of IBD-related colon dysplasia (IBD-dys) in Hispanics versus non-Hispanic whites (NHWs) and compare differences in established clinical and environmental risk factors.

Methods

We performed a cross-sectional analysis on adult Hispanics and NHWs with IBD who met criteria for colorectal cancer surveillance and were followed at our center between 2008 and 2018. Clinical variables and IBD phenotype were recorded. Lifestyle IBD-dys risk factors were examined, including smoking and lack of physical activity. Using multivariable regression, we compared the prevalence of IBD-dys in Hispanics versus NHW, using relevant covariates. Receiver operating characteristic and area under the curve were performed to find the best fitting model.

Results

A total of 445 IBD patients were included (148 Hispanics and 297 NHWs). IBD phenotype was similar between groups, except that Hispanics had shorter disease duration, a lower frequency of Crohn's disease-related complications, and lower reported use of steroids. Frequency of surveillance colonoscopies was similar between Hispanics and NHW. There were no differences in median body mass index between Hispanics and NHW [26.5 (IQR 6.0) vs 25.0 (IQR 6.0), P = 0.40]. Hispanics were less likely than NHW to consume alcohol but smoking history was similar between groups. Three out of 148 Hispanic patients had IBD-dys (2.02%) compared to 29 out of 297 NHWs (9.76%). Adjusting for disease duration, primary sclerosing cholangitis, family history of colon cancer, and smoking, Hispanics had a lower prevalence of IBD-dys compared to NHW [OR_adjusted = 0.207 (95% CI 0.046-0.938), P = 0.008].

Conclusions

Hispanics with IBD undergoing surveillance had a lower prevalence of IBD-dys than their NHW counterparts, despite similar risk factors. Future studies should examine dietary and microbial factors that may explain differences in risk.

Project description:BackgroundHypertension is a significant risk factor for intracerebral hemorrhage (ICH). Although ethnic/racial disparities related to hypertension and ICH have been reported, these previous studies were limited by a lack of Hispanics and inadequate power to analyze by ICH location. In the current study, while overcoming these prior limitations, we investigated whether there was variation by ethnicity/race of treated and untreated hypertension as risk factors for ICH.MethodsThe ERICH study (Ethnic/Racial Variations of Intracerebral Hemorrhage) is a prospective, multicenter, case-control study of ICH among whites, blacks, and Hispanics. Cases were enrolled from 42 recruitment sites. Controls matched to cases 1:1 by age (±5 years), sex, ethnicity/race, and metropolitan area were identified by random-digit dialing. Subjects were interviewed to determine history of hypertension and use of antihypertensive medications. Cases and controls within ethnic groups were compared by using conditional logistic regression. Multivariable conditional logistic regression models were computed for ICH as an overall group and separately for the location subcategories deep, lobar, and infratentorial (brainstem/cerebellar).ResultsNine hundred fifty-eight white, 880 black, and 766 Hispanic ICH patients were enrolled. For ICH cases, untreated hypertension was higher in blacks (43.6%, P<0.0001) and Hispanics (46.9%, P<0.0001) versus whites (32.7%). In multivariable analyses adjusted for alcohol use, anticoagulation, hypercholesterolemia, education, and medical insurance status, treated hypertension was a significant risk factor across all locations of ICH in whites (odds ratio [OR], 1.57; 95% confidence interval [CI], 1.24-1.98; P<0.0001), blacks (OR, 3.02; 95% CI, 2.16-4.22; P<0.0001), and Hispanics (OR, 2.50; 95% CI, 1.73-3.62; P<0.0001). Untreated hypertension was a substantially greater risk factor for all 3 racial/ethnic groups across all locations of ICH: whites (OR, 8.79; 95% CI, 5.66-13.66; P<0.0001), blacks (OR, 12.46; 95% CI, 8.08-19.20; P<0.0001), and Hispanics (OR, 10.95; 95% CI, 6.58-18.23; P<0.0001). There was an interaction between race/ethnicity and ICH risk (P<0.0001).ConclusionsUntreated hypertension confers a greater ICH risk in blacks and Hispanics relative to whites across all anatomic locations of ICH. Accelerated research efforts are needed to improve overall hypertension treatment rates and to monitor the impact of such efforts on racial/ethnic disparities in stroke.Clinical trial registrationURL: http://www.clinicaltrials.gov.
