ABSTRACT

Objectives@#It is important that inflammatory bowel disease (IBD) patients adhere to their prescribed medication regimens to avoid the repeat exacerbations, complications, or surgeries associated with this disorder. However, there are few studies on medication adherence in patients with IBD, especially in Asian populations. So, we analyzed the factors associated with medication adherence in Korean IBD patients. @*Methods@#Patients who had been diagnosed with Crohn’s disease (CD) or ulcerative colitis (UC) more than 6 months previously and receiving oral medications for IBD were enrolled. Medication adherence was measured using the Medical Adherence Reporting Scale (MARS-5), a self-reported medication adherence measurement tool. @*Results@#Among 207 patients in the final study population, 125 (60.4%) had CD and 134 (64.7%) were men. The mean age was 39.63 years (SD, 13.16 years) and the mean disease duration was 10.09 years (SD, 6.33 years). The mean medication adherence score was 22.46 (SD, 2.86) out of 25, and 181 (87.4%) patients had score of 20 or higher.In multiple linear regression analysis, self-efficacy (β=0.341, P<0.001) and ≥3 dosing per day (β=–0.192 P=0.016) were revealed to be significant factors associated with medication adherence. Additionally, there was a positive correlation between self-efficacy and medication adherence (r=0.312, P<0.001). However, disease related knowledge, depression, and anxiety were not significantly associated with medication adherence. @*Conclusion@#To improve medication adherence among patients with IBD, a reduction in the number of doses per day and an improved self-efficacy will be helpful.

ABSTRACT

Background/Aims@#Data on the immunoprotective status against measles, mumps, rubella, varicella zoster virus (VZV), hepatitis A virus (HAV), and Epstein-Barr virus (EBV) infection in patients with inflammatory bowel disease (IBD) are still lacking. Therefore, we investigated the seropositivity rates for viral infectious diseases and the associated factors in Korean patients with IBD. @*Methods@#In this retrospective cohort study, serum immunoglobulin G antibody positivity rates against measles virus, mumps virus, rubella virus, VZV, HAV, and EBV viral capsid antigen (VCA) were measured in patients with Crohn’s disease or ulcerative colitis (UC) who first visited the IBD clinic. Seropositivity rates and their associated factors were analyzed. @*Results@#Between January 2016 and December 2018, 263 patients were enrolled (male, 167 [67.3%]; UC, 134 [50.9%]). The median age at serological test was 30 years (interquartile range, 22 to 46). The seropositivity rates were 84.0%, 85.2%, 66.5%, 87.4%, 50.0%, and 93.7% for measles, mumps, rubella, VZV, HAV, and EBV, respectively. Younger age at serological test was associated with seronegative status for measles (adjusted odds ratio [aOR], 0.92; 95% confidence interval [CI], 0.88 to 0.96), VZV (aOR, 0.83; 95% CI, 0.74 to 0.93), and HAV (aOR, 0.93; 95% CI, 0.91 to 0.95). Furthermore, IBD type-UC was associated with seronegative status against VZV (aOR, 0.33; 95% CI, 0.11 to 0.99). @*Conclusions@#Seropositivity rates for common viral infectious diseases in Korean patients with IBD were similar to those of the general population. In the younger age group, protective immunity against measles, VZV, and HAV is required, with proper vaccination, as necessary.

ABSTRACT

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.

ABSTRACT

Background/Aims@#Self-expandable metal stents (SEMSs) can be applied to relieve colorectal obstruction secondary to incurable primary colorectal cancer or extracolonic malignancy. We aimed to identify factors associated with clinical success and the reintervention-free survival (RFS) after palliative stenting. @*Methods@#Cases of palliative SEMS placement between 2005 and 2019 were retrieved from the institutional database and reviewed retrospectively. Logistic regression and log-rank testing followed by Cox proportional hazard analyses were performed to investigate the predictors of the clinical success of palliative stenting and factors associated with RFS, respectively. @*Results@#A total of 593 patients underwent palliative stenting for malignant colonic obstruction (MCO). The technical and clinical success rates were 92.9% and 83.5%, respectively. Peritoneal carcinomatosis was a predictor of clinical failure (odds ratio, 0.33; 95% confidence interval [CI], 0.17 to 0.65) in the multivariate analysis. Peritoneal carcinomatosis (hazard ratio [HR], 2.48; 95% CI, 1.69 to 3.64) and stent expansion >90% on day 1 (HR, 1.62; 95% CI, 1.05 to 2.50) were associated with a shorter RFS. Neither clinical success nor RFS was associated with extracolonic malignancy. Re-obstruction, stent migration, and perforation were responsible for most reinterventions after clinically successful palliative stenting. @*Conclusions@#In patients requiring palliative stenting for MCO, peritoneal carcinomatosis was associated with both clinical failure and short RFS. Stent expansion >90% on postprocedural day 1 was another predictor of a short RFS after clinically successful stenting. A large prospective study is warranted to establish factors associated with RFS after successful palliative stenting for MCO.

ABSTRACT

The phosphorous balance is clinically important in increasing the long-term outcomes and preventing complications of end-stage renal disease. Sevelamer is a phosphate binder used widely to regulate hyperphosphatemia. On the other hand, gastrointestinal side effects increase with increasing sevelamer intake. A 29-year-old male with end-stage renal disease of IgA nephropathy on maintenance hemodialysis was admitted for diffuse alveolar bleeding and pneumonia. He presented with a low-grade fever and watery diarrhea tinged with blood. Initially, a Clostridioides difficile-associated diarrhea treatment was started with positive findings of Clostridioides difficile toxin and culture. Despite this, there was no improvement in the symptoms even with the appropriate antibiotic treatment. Computed tomography of the abdomen and pelvis revealed an occlusive mass in the rectum and secondary obstructive changes in the sigmoid colon. The initial suspicion was a malignancy or fungal infection. Sigmoidoscopy with a biopsy identified the mass as a lump of mucous material with the entire lumen covered with exudate. The subsequent histopathology examination revealed a colonic mucosal injury and characteristic ''fish scale"-like sevelamer crystals in the exudate. The diagnosis of a sevelamer-induced rectal ulcer was made. We report this case of a sevelamer-associated rectal ulcer of the sigmoid.

ABSTRACT

In 2020, the novel coronavirus disease 2019 (COVID-19) began to spread worldwide and remains an ongoing medical challenge. This case series reports on the clinical features and characteristics of patients with inflammatory bowel disease (IBD) and confirmed COVID-19 infection. From February 2020 to March 2021, nine patients with IBD had confirmed COVID-19 across four hospitals in Korea. The median age at COVID-19 diagnosis was 42 years. Six patients were male, and seven patients had ulcerative colitis (UC). No patients required oxygen therapy, intensive care unit hospitalizations, or died. The most common symptom was fever, and gastrointestinal (GI) symptoms developed as diarrhea in five patients with UC. Oral steroids were used to combat UC aggravation in two patients. In this case series of nine IBD patients diagnosed with COVID-19 in Korea, the clinical presentation was predominately a mild respiratory tract infection. Most patients with UC developed new GI symptoms including diarrhea.

ABSTRACT

Background/Aims@#Studies on long-term outcomes of adalimumab therapy in non-Caucasian patients with ulcerative colitis (UC) are lacking. @*Methods@#We analyzed long-term outcomes of Korean UC patients treated with adalimumab at the Asan Medical Center, Seoul, Korea. @*Results@#Between July 2013 and October 2018, adalimumab therapy was started in a total of 100 patients with UC (65 males [65.0%]; median age, 39.5 years [interquartile range, 23.3 to 49.8 years]; and median disease duration, 3.0 years [interquartile range, 1.0 to 7.0 years]). The median duration of adalimumab therapy was 13.5 months (interquartile range, 4.0 to 32.0 months). Eight of 100 patients (8.0%) received induction therapy only, four (4.0%) of whom ultimately underwent colectomy. Of 92 patients who received adalimumab maintenance therapy, 30 (30.0%) stopped adalimumab therapy due to loss of response, and one patient (1.0%) was lost to follow-up. Among the 92 patients who received adalimumab maintenance therapy, the cumulative proportions of patients remaining on adalimumab maintenance therapy were 70.0% at 1 year and 48.9% at 5 years. High partial Mayo score after 8 weeks of adalimumab therapy (hazard ratio [HR], 1.217; 95% confidence interval [CI], 1.040 to 1.425; p=0.014) and a history of exposure to two biologic agents before adalimumab therapy (HR, 4.722; CI, 1.033 to 21.586; p=0.045) were predictors of adalimumab discontinuation. @*Conclusions@#Long-term outcomes of adalimumab therapy in Korean UC patients appear to be comparable to those in previously published Western studies. Furthermore, previous exposure to multiple biologic agents before adalimumab therapy and disease activity after 8 weeks of adalimumab therapy were predictors of adalimumab discontinuation.

ABSTRACT

Background/Aims@#We aimed to investigate the proportion of and risk factors for residual cancer and/or lymph node metastasis after surgery was performed because of high-risk pathological features in endoscopic resection specimen of suspected superficial submucosal colorectal cancer (SSMC). @*Methods@#We reviewed medical records of 497 patients (58.8 ± 9.8 years, 331 males) undergoing endoscopic resection of suspected SSMC. High-risk pathological features included: deep submucosal cancer invasion ≥ 1,000 μm; positive lymphovascular and/or perineural invasion; poorly differentiated adenocarcinoma; and positive resection margin. We investigated the occurrence of additional surgery and residual cancer and/or lymph node involvement in the surgical specimen. @*Results@#En bloc resection was performed in 447 patients (89.9%). High-risk pathological features were detected in 372 patients (74.8%). Additional surgery was performed in 336 of 372 patients with high-risk pathological features. Of these, 47 surgical specimens (14.0%) showed residual cancer and/or lymph node metastasis. Piecemeal resection was more common in those with residual cancer and/or lymph node involvement than those without (9/47 [19.1%] vs. 24/289 [8.3%], P= 0.032). Positive resection margin was also significantly associated with positive residual cancer and/or lymph node involvement. As the number of high-risk pathological features increased, the risk of regional lymph node metastasis increased proportionally (P= 0.002). @*Conclusions@#High-risk pathological features were frequently detected after endoscopic resection of suspected SSMC while residual cancer and/or lymph node metastasis were not commonly present in the additional surgical specimen. Further optimized strategy for proper endoscopic management of suspected SSMC is necessary.

ABSTRACT

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.

ABSTRACT

BACKGROUND/AIMS: Previous studies from Korea have described chronic intestinal pseudo-obstruction (CIPO) patients with transition zone (TZ) in the colon. In this study, we evaluated the pathological characteristics and their association with long-term outcomes in Korean colonic pseudo-obstruction (CPO) patients with TZ. METHODS: We enrolled 39 CPO patients who were refractory to medical treatment and underwent colectomy between November 1989 and April 2016 (median age at symptoms onset: 45 [interquartile range, 29–57] years, males 46.2%). The TZ was defined as a colonic segment connecting a proximally dilated and distally non-dilated segment. Detailed pathologic analysis was performed. RESULTS: Among the 39 patients, 37 (94.9%) presented with TZ and 2 (5.1%) showed no definitive TZ. Median ganglion cell density in the TZ adjusted for the colonic circumference was significantly decreased compared to that in proximal dilated and distal non-dilated segments in TZ (+) patients (9.2 vs 254.3 and 150.5, P < 0.001). Among the TZ (+) patients, 6 showed additional pathologic findings including eosinophilic ganglionitis (n = 2), ulcers with combined cytomegalovirus infection (n = 2), diffuse ischemic changes (n = 1), and heterotropic myenteric plexus (n = 1). During follow-up (median, 61 months), 32 (82.1%) TZ (+) patients recovered without symptom recurrence after surgery. The presence of pathological features other than hypoganglionosis was an independent predictor of symptom recurrence after surgery (P = 0.046). CONCLUSIONS: Hypoganglionosis can be identified in the TZ of most Korean CPO patients. Detection of other pathological features in addition to TZ-associated hypoganglionosis was associated with poor post-operative outcomes.

ABSTRACT

BACKGROUND/AIMS: This study compared the efficacy, compliance, and safety of bowel preparation between sodium picosulfate with magnesium citrate (SPMC) and oral sulfate solution (OSS). METHODS: A prospective randomized multicenter study was performed. Split preparation methods were performed in both groups; the SPMC group, 2 sachets on the day before, and 1 sachet on the day of the procedure, the OSS group, half of the OSS with 1 L of water on both the day before and the day of the procedure. The adenoma detection rate (ADR), adequacy of bowel preparation using the Boston Bowel Preparation Scale (BBPS) score, patient satisfaction on a visual analog scale (VAS), and safety were compared between the 2 groups. RESULTS: This study analyzed 229 patients (121 in the SPMC group and 108 in the OSS group). ADR showed no differences between 2 groups (51.7% vs. 41.7%, P>0.05). The mean total BBPS score (7.95 vs. 8.11, P>0.05) and adequate bowel preparation rate (94.9% vs. 96.3%, P>0.05) were similar between the 2 groups. The mean VAS score for taste (7.62 vs. 6.87, P=0.006) was significantly higher in the SPMC group than in the OSS group. There were no significant differences in any other safety variables between the 2 groups except nausea symptom (36.1% vs. 20.3%, P=0.008). CONCLUSIONS: Bowel preparation for colonoscopy using low volume OSS and SPMC yielded similar ADRs and levels of efficacy. SPMC had higher levels of satisfaction for taste and feeling than did OSS.

ABSTRACT

BACKGROUND/AIMS: α-Synucleinopathy in the brain is the neuropathological hallmark of Parkinson’s disease (PD). However, the functional impact of α-synucleinopathy in the enteric nervous system remains unknown. We aim to evaluate the association between gastrointestinal (GI) dysfunction and α-synuclein (αSYN) pathology in the stomach and colon of PD patients and controls, as well as to investigate the association between the αSYN pathology in GI tract and future PD risk. METHODS: A total of 35 PD patients and 52 neurologically intact subjects were enrolled in this study. Endoscopic biopsies were performed, and then immunohistochemical staining for αSYN was performed. All subjects completed the validated Rome III questionnaire for the assessment of GI symptoms. The association between GI symptoms and the αSYN pathology in GI mucosa was evaluated. Incident PD cases were assessed during a median follow-up of 46 months. RESULTS: The proportion of self-reported constipation and functional constipation through the Rome III questionnaire was significantly higher in PD patients than in controls (P 0.05). No incident PD cases were diagnosed during study period. CONCLUSIONS: Our present study suggests that the deposition of αSYN in the mucosal enteric nervous system may not be reflected by functional impairment of the affected segment of the gut.

ABSTRACT

BACKGROUND: We investigated the incidence of active tuberculosis among patients with inflammatory bowel disease (IBD) treated with tumor necrosis factor (TNF) inhibitors, with or without latent tuberculosis infection (LTBI). METHODS: The study was performed at a Korean tertiary referral center between January 2011 and June 2017. In total, 740 patients with IBD who underwent LTBI screening tests and were followed-up for ≥ 1 year after TNF inhibitor treatment initiation were enrolled. LTBI was detected on the basis of tuberculin skin test results, interferon-gamma release assay results, chest X-ray findings, and previous tuberculosis treatment history. The patients were classified into LTBI (n = 84) or non-LTBI (n = 656) group. The risk of developing tuberculosis in each group was assessed on the basis of standardized incidence ratio (SIR) and 95% confidence interval (CI) for active tuberculosis. RESULTS: Mean patient age was 33.1 years, and patients with Crohn's disease were predominant (80.7%). Within 1 year after the initiation of TNF inhibitor treatment, 1 patient in the LTBI group (1/84; 1.2%) and 7 patients in the non-LTBI group (7/656; 1.1%) developed active tuberculosis. The overall 1-year incidence of tuberculosis among the patients was significantly higher than that among the general population (SIR, 14.0; 95% CI, 7.0–28.0), and SIR was not affected by LTBI status (LTBI group: 14.5, 95% CI, 2.0–102.6; non-LTBI group: 14.0, 95% CI, 6.7–29.4). CONCLUSION: Patients with IBD undergoing TNF inhibitor treatment showed a higher 1-year incidence of tuberculosis than the general population irrespective of LTBI status.

ABSTRACT

Patients with inflammatory bowel disease (IBD) have been reported to have an increased risk of thromboembolism. Cerebral venous thrombosis (CVT) is a rare but serious extraintestinal manifestation of IBD. Due to its highly variable manifestation and low incidence, CVT is not usually readily recognized by physicians. Herein, we report a case of a 35-year-old male presenting with CVT associated with ulcerative colitis (UC). The patient was admitted with chief complaints of bloody diarrhea that had started 3 days prior. Sigmoidoscopy showed hyperemic and edematous mucosa, friability, and shallow ulcers from the sigmoid colon to the rectum suggestive of IBD. Three days later, the patient started complaining of a headache, and gradually developed a decreased level of consciousness. Magnetic resonance imaging of the brain revealed CVT with hemorrhagic infarctions. An angiogram was obtained to evaluate the extent of CVT, and anticoagulation therapy was initiated with intravenous heparin. During hospitalization, he was diagnosed with UC and treated with 5-aminosalicylic acid. After discharge, the patient was recovered without neurological deficit, and remission of UC was also obtained. The presence of headache or acute worsening of neurological status in a patient with IBD should alert the health professionals about the possibility of CVT.

ABSTRACT

BACKGROUND/AIMS: The clinical outcomes of angiography and transcatheter arterial embolization (TAE) for acute gastrointestinal bleeding (GIB) have not been completely assessed, especially according to bleeding sites. This study aimed to assess the efficacy of angiography and safety of TAE in acute GIB. METHODS: This was a retrospective study evaluating the records of 321 patients with acute GIB who underwent angiography with or without TAE. Targeted TAE was conducted in 134 patients, in whom angiography showed bleeding sources. Prophylactic TAE was performed in 29 patients when the bleeding source was not detected but a specific vessel was strongly suspected by other examinations. The rate of technical success, clinical success, and complications were analyzed. RESULTS: The detection rate of bleeding source via angiography was 50.8% (163/321), which was not different according to the bleeding sites. The detection rate was higher if the probable bleeding source had already been found by another investigation (59.7% vs. 35.8%, p<0.001). TAE sites were upper GIB in 67, mid GIB in 74, and lower GIB in 22. The technical success rate was 99.3% (133/134), and the clinical success rate was 63.0% (104/163). The prophylactic embolization group showed lower clinical success rate than the targeted embolization group (44.8% vs. 67.9%, p=0.06). The TAE-related complication rate was 12.9% (21/163). Ischemia and/or infarction was more common after TAE for mid and lower GIB than for upper GIB (15.6% vs. 3.0%, p=0.007). CONCLUSIONS: Angiography with or without TAE was an effective method for acute GIB. Targeted embolization should be performed if possible given that it has a higher clinical success rate.

ABSTRACT

BACKGROUND/AIMS: The reported rates of current smoking at the time of Crohn’s disease (CD) diagnosis tend to be low in East Asian studies. However, we hypothesized that East Asian patients may be reluctant to disclose their smoking history, likely because of the influence of the Confucian culture. METHODS: We prospectively re-evaluated the smoking status at diagnosis in 1,437 Korean CD patients whose smoking status had been reported in our previous study. RESULTS: After re-evaluation, the current smokers at diagnosis increased from 388 patients (27.0%) to 445 patients (31.0%), indicating that 12.8% (57 of 445 patients) of the current smokers at diagnosis did not disclose their smoking status at their initial evaluation. The proportion of current smokers at diagnosis who had initially concealed their smoking status was significantly higher among the female patients (29.7%, 11/37) compared with the male patients (11.3%, 46/408) (p18 years old at diagnosis (8.6%, 35/406) (p<0.001). CONCLUSIONS: Subgroups of Korean CD patients, particularly young patients and female patients, are reluctant to disclose their smoking history. Therefore, the suggestion that smoking is not a risk factor for the development of CD in East Asians should be made with caution.

ABSTRACT

BACKGROUND/AIMS: Endoscopic resection is the first-line treatment for rectal neuroendocrine tumors (NETs) measuring < 1 cm and those between 1 and 2 cm in size. However, conventional endoscopic resection cannot achieve complete resection in all cases. We aimed to analyze clinical outcomes of precut endoscopic mucosal resection (EMR-P) used for the management of rectal NET. METHODS: EMR-P was used to treat rectal NET in 72 patients at a single tertiary center between 2011 and 2015. Both, circumferential precutting and EMR were performed with the same snare device in all patients. Demographics, procedural details, and histopathological features were reviewed for all cases. RESULTS: Mean size of the tumor measured endoscopically was 6.8±2.8 mm. En bloc and complete resection was achieved in 71 (98.6%) and 67 patients (93.1%), respectively. The mean time required for resection was 9.0±5.6 min. Immediate and delayed bleeding developed in six (8.3%) and 4 patients (5.6%), respectively. Immediate bleeding observed during EMR-P was associated with the risk of delayed bleeding. CONCLUSIONS: Both, the en bloc and complete resection rates of EMR-P in the treatment of rectal NETs using the same snare for precutting and EMR were noted to be high. The procedure was short and safe. EMR-P may be a good treatment choice for the management of rectal NETs.
