Background/Aims Fecal S100A12 (FS) and serum S100A12 (SS) have been reported as novel biomarkers that accurately reflect intestinal inflammation. We evaluated if FS and SS in comparison to fecal calprotectin (FC) are associated with poor future outcomes in clinically quiescent Crohn’s disease (CD) patients.
Methods We prospectively enrolled 49 CD patients in clinical remission (Crohn’s Disease Activity Index [CDAI] < 150 for the past 6 months). Patients were followed for a median period of 4.4 years (interquartile range [IQR], 4.3–4.5). The following outcomes were evaluated: clinical relapse, CD-related hospitalization, step-up of medical treatment, and CD-related intestinal resection. Cox proportional-hazard regression model was constructed to assess the association of baseline markers with time-to-event outcomes.
Results The median levels of baseline FS, FC, and SS were 0.042 mg/kg (IQR, 0.005–0.179), 486.8 mg/kg (IQR, 203.5–886.8) and 1,398.2 ng/mL (IQR, 791.8–2,759.9), respectively. FS correlated with FC (r = 0.689), erythrocyte sedimentation rate (r = 0.524), C-reactive protein (r = 0.499), and albumin (r = –0.446), but not with CDAI (r = 0.045). Interestingly, increased FS (top quartile) was associated with a 4.9-fold increased rate of future CD-related hospitalization (P= 0.009) and a 2.8-fold increased rate of step-up of medical treatment (P= 0.032), whereas increased FC and SS were not. These findings remained significant after adjusting for age, sex, disease duration, current smoking, C-reactive protein, serum albumin, CDAI, and FC, individually.
Conclusions In this pilot study, increased FS and not FC or SS, was significantly associated with increased rates of future CD-related hospitalization and step-up of medical treatment among CD patients in clinical remission.

Background/Aims The use of complementary and alternative medicine (CAM) is a global phenomenon, including inflammatory bowel disease (IBD) patients. We aimed to assess the change in prevalence and patterns of CAM use, and attitudes towards CAM over an 8-year time interval (2006 vs. 2014) among IBD patients in Korea.
Methods A total of 221 IBD patients (CD=142, UC=79) were asked to complete a questionnaire regarding CAM at two time points: at enrollment (2006) and 8 years later (2014/2015).
Results The proportion of patients ever using CAM increased significantly from 60.2% in 2006 to 79.6% in 2014 (P<0.001), while the proportion of current CAM users increased slightly (35.7% to 38.0%, P=0.635); 21.7% used CAM consistently at both time points. The proportion of patients who felt CAM was less effective (P<0.001) and more expensive (P=0.04) than conventional treatments increased over time. Also, the proportion among ever CAM users who perceived a positive effect from CAM significantly decreased in 2014 compared to 2006 (P=0.004). Higher education (adjusted odds ratio [aOR], 2.10), prior side effects to conventional therapies (aOR, 2.23), and prior use of corticosteroids (aOR, 2.51) were associated with CAM use. Interestingly, use of CAM before IBD diagnosis (aOR, 2.73) was significantly associated with consistent CAM use.
Conclusions Although the attitudes toward CAM have become less favorable, the majority of IBD patients have experienced CAM with an overall increase of current CAM users over time. Moreover, more than half of current CAM users used CAM consistently over time.
