The mean age was higher among users of both medications than users of neither (61.2 vs. 54.1, P<0.0001). There was a difference between the groups in terms of gender breakdown (P=0.01), racial breakdown (P=0.04), BMI (P=0.002), presence of diabetes (P<0.0001) and hypertension (P<0.0001). Medication users and non-users did not differ in any other factors. Table 6 shows the association between users of both medications Inhibitors,research,lifescience,medical and colonoscopy findings, adjusted for age, sex, race, BMI, diabetes, hypertension and
smoking or alcohol use. Compared to non-users of either medication, those who used both had an increased risk for having two or more adenomas (OR =2.56, 95% CI: 1.21, 5.39, P=0.01). No associations were seen between any other colonoscopy findings and aspirin use in the total population. In the Hispanic population, compared to non-users of either medication, those who used both had an increased risk for having two or more adenomas (OR =19.04, 95% CI: 1.30, 280.09, P=0.03), adenoma present in the distal colon (OR =5.75, 95% CI:
1.64, 20.21, P=0.01) and Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical largest adenoma in distal colon (OR =5.75, 95% CI: 1.64, 20.21, P=0.01). No other associations were seen in the Hispanic population. Table 5 Demographics of aspirin and statin users and non-users undergoing colonoscopy Table 6 Association between aspirin and statin use and colonoscopy findings in total population and Hispanics Inhibitors,research,lifescience,medical Discussion To our knowledge this is the first study assessing aspirin and statin use in a Hispanic population. We found that statin use was not associated with any colonoscopy findings, though aspirin use increased the risk for two or more adenomas and adenoma in the proximal colon in our total population, but did not see the
same results when restricting the analysis to Hispanics. An increased risk for two or more adenomas was also seen in the total population for users of both statins and aspirin. In Hispanics, use of both medications was associated with two or more adenomas, adenoma present in the distal colon and largest adenoma in distal colon. There have been many trials discussing Inhibitors,research,lifescience,medical the Saracatinib price relationship between aspirin/non-steroidal anti-inflammatory drugs (NSAIDs) and colorectal adenoma/carcinomas in predominant white patient populations. One recent meta-analysis combined four randomized double-blinded placebo trials that evaluated aspirin and prevention of CRA. The results showed that aspirin users had a pooled risk Metalloexopeptidase ratio of 0.83 (95% CI: 0.72, 0.96) for any adenoma, with an absolute risk reduction of 6.7% compared to placebo (6). They concluded that aspirin is effective for the prevention of CRA in patients with a history of these lesions. There have also been studies looking specifically at NSAIDS and colon cancer. Patients taking 200mg BID of Celecoxib had a reduced rate of sporadic CRA (RR: 0.67, 95% CI: 0.59, 0.77), while those taking 400 mg BID also had a reduced risk of sporadic CRA (RR: 0.55, 95% CI: 0.48, 0.64) (7).
