An extensive array of compounds has been studied for the treatment of ulcerative colitis (UC). The most frequently used nonbiologic drugs for the oral and intravenous treatment of ulcerative colitis include 5-aminosalicylate (5-ASA) drugs (mesalamine and derivatives), sulfasalazine, and other azo-bonded molecules of 5-ASA, steroids, calcineurin inhibitors (cyclosporine, tacrolimus, and sirolimus), thiopurines (azathioprine, 6-mercaptopurine), and methotrexate, which are already presented in other sections of this book and are thus not considered in this chapter. The therapies presented in this section should be considered as potential alternatives, mostly for mild-to-moderate ulcerative colitis (UC). They are substances mostly used without FDA indications, such as heparin, nicotine, rosiglitazone, and N-acetylcysteine as well as “natural” compounds suggested to have anti-inflammatory or reparative properties, such as aloe vera, curcumin, short-chain fatty acids, and Bowman-Birk inhibitor

INTRODUCTION The high risk of cardiovascular events in smokers requires adequate control of other cardiovascular risk factors (CVRFs) to curtail atherosclerosis progression. However, it is unclear which CVRFs have the most influence on atherosclerosis progression in smokers. METHODS In 260 smokers aged 40-70 included in a smoking cessation trial, we analyzed the association between traditional CVRFs, high-sensitivity C-reactive protein (hs-CRP), smoking cessation and 3-year progression of carotid intima-media thickness (CIMT, assessed by repeated ultrasound measurements) in a longitudinal multivariate model. RESULTS Participants (mean age 52 years, 47% women) had a mean smoking duration of 32 years with a median daily consumption of 20 cigarettes. Baseline CIMT was 1185 μm (95% confidence interval [CI]: 1082-1287) and increased by 93 μm (95% CI: 25-161) and 108 μm (95% CI: 33-183) after 1 and 3 years, respectively. Age, male sex, daily cigarette consumption, systolic blood pressure (SBP), but neither low-density lipoprotein cholesterol nor hs-CRP, were independently associated with baseline CIMT (all P ≤ .05). Baseline SBP, but neither low-density lipoprotein cholesterol nor hs-CRP, was associated with 3-year atherosclerosis progression (P = .01 at 3 years). The higher the SBP at baseline, the steeper was the CIMT increase over 3-year follow-up. We found an increase of 26 μm per each 10-mmHg raise in SBP at 1 year and an increase of 39 μm per each 10 mmHg raise in SBP at 3 years. Due to insufficient statistical power, we could not exclude an effect of smoking abstinence on CIMT progression. CONCLUSION Control of blood pressure may be an important factor to limit atherosclerosis progression in smokers, besides support for smoking cessation. IMPLICATIONS Among 260 smokers aged 40-70 years with a mean smoking duration of 32 years, baseline SBP was associated with atherosclerosis progression over 3 years, as measured by CIMT (P = .01 at 3 years), independently of smoking variables and other CVRFs. The higher the SBP at baseline, the steeper was the CIMT increase over 3-year follow-up. Our findings emphasize the importance of focusing not only on smoking cessation among smokers, but to simultaneously control other CVRFs, particularly blood pressure, in order to prevent future cardiovascular disease.
