Adherence to Asacol once daily versus divided regimen for maintenance therapy in ulcerative colitis: a prospective, multicenter, randomized study: Soo-Kyung Park, Sang Hyun Park, Chang Soo Eun, Geom Seog Seo, Jong Pil Im, Tae Oh Kim, Dong-Il Park; Intest Res 2019;17(3):349-356. Published online February 8, 2019; DOI: https://doi.org/10.5217/ir.2018.00064

Background/Aims
A once-daily (OD) regimen of 5-aminosalicylic acid (5-ASA) was easier to comply with than a divided daily (DD) regimen, and that treatment efficacy for ulcerative colitis (UC) was not affected by the dosing regimen. This study evaluated treatment adherence of OD and DD dosing in the Korean UC patients.
Methods
This study was a prospective, multicenter, randomized trial. UC patients were enrolled who have been in remission for more than 3 months. Patients were randomly assigned to the OD or DD group in a 1:1 ratio. The primary endpoint was adherence rate measured by tablet counts and self-reported adherence rate at 3, 6, 9, and 12 months. The relapse rate was measured at 1 year.
Results
Data from the 180 patients who were randomized were analyzed. Both self-reported adherence rate and adherence rate measured by tablet counts were not different at every points, including 1 year. The patients’ satisfaction of the OD group was higher than that of the DD group (P<0.001). At 1 year, 91.2% and 95.5% of patients in the OD group and DD group had maintained clinical remission, respectively (P=0.37).
Conclusions
The adherence rates were not different between the OD group and DD group. The patients’ satisfaction was higher in the OD group than in the DD group. 5-ASA OD dosing might have the same effect as DD for the maintenance of UC remission.

<b>Background/Aims</b><br/>

The purpose of this study was to evaluate the clinicopathologic characteristics of colon cancers detected at the SOK Sokpeynhan Internal Medical Network, a nationwide system of primary health care institutions.

Methods

We analyzed 579 colon cancer patients diagnosed using colonoscopy at the SOK network from January 2011 through December 2012. Cancers from the rectum to the splenic flexure were classified as left colon cancer. Patients over 65 were classified as senior.

Results

The mean age (±SD) of subjects was 60.9±10.5 years and 61.1% were men. More than one quarter (28.2%) of patients were asymptomatic. The prevalence of left colon cancer was higher (77.9%) than that for right colon cancer. The most frequent macroscopic and histologic types were depressed (58.9%) and moderately differentiated adenocarcinoma (52.2%), respectively. Asymptomatic subjects displayed protruding or well differentiated adenocarcinoma, while symptomatic patients were more likely to display depressed or moderately differentiated adenocarcinoma (P<0.05). The mean age of the right colon cancer group was higher than that for the left colon cancer group (P<0.05). Among symptomatic patients, the most frequent symptoms were bloody stool for patients with left colon cancer and abdominal discomfort for patients with right colon cancer (P<0.05). The prevalence of depressed cancer was higher in older subjects as compared to younger subjects (P<0.05). The prevalence of right colon cancer tended to increase with age, although this difference did not achieve statistical significance (P>0.05).

Conclusions

Study results indicated an increase of colon cancer amongst younger demographics in recent years. The effectiveness of colonoscopy screening was also evident, as asymptomatic patients demonstrated frequent findings of well differentiated adenocarcinomas. Study results also suggested a need for closer examination of older patients, as right colon cancer tended to increase with age.

Usefulness of C-reactive Protein Level before and during Antimycobacterial Therapy in the Differential Diagnosis between Crohn's Disease and Intestinal Tuberculosis: Sang Hyun Park, Suk-Kyun Yang, Seung-Jae Myung, Jeong-Sik Byeon, Byongduk Ye, Seunghyun Kwon, Benjamin Kim, Soon Man Yoon, Mi Young Do, Do Hoon Kim, Sai-Hui Kim, Jin Ho Kim; Intest Res 2007;5(1):19-25.

Abstract PDF: Background/Aims
Crohn's disease (CD) and intestinal tuberculosis (TB) are chronic inflammatory bowel disorders that are difficult to differentiate. Therefore, a therapeutic trial of antimycobacterial drugs is often used to differentiate CD from TB. This study aimed to evaluate the usefulness of C-reactive protein (CRP) level before or during antimycobacterial therapy to differentiate CD from TB. Methods: A total of 26 CD patients and 52 TB patients who received antimycobacterial therapy at the Asan Medical Center were included. CRP levels before or during antimycobacterial therapy were compared between CD and TB patients. A positive response to antimycobacterial therapy was defined as the decrease of CRP level below 50% of its baseline value. Results: The baseline CRP level was normal in only 1 of 26 CD patients (3.8%), while it was in 26 of 52 TB patients (50%). The rate of positive response to antimycobacterial therapy was significantly different between CD and TB patients whose baseline CRP level was abnormal: 28.0% (7/25) vs 88.5% (23/26) in 2 weeks, 34.8% (8/23) vs 84.6% (22/26) in 4 weeks, and 43.5% (10/23) vs 92.3% (24/26) in 8 weeks of antimycobacterial therapy. The rate of normalization in CRP level was also significantly different between the two groups: 0% (0/25) vs 73.1% (19/26) in 2 weeks, 13.0% (3/23) vs 69.2% (18/26) in 4 weeks, and 8.7% (2/23) vs 80.8% (21/26) in 8 weeks of antimycobacterial therapy. Conclusions: The CRP level before and during antimycobacterial therapy may be used as a supplementary tool in the differential diagnosis between CD and TB patients. (Intest Res 2007;5:19-25)
