Background/Aims
Nutritional status influences quality of life among patients with inflammatory bowel disease (IBD), although there is no clear method to evaluate nutritional status in this setting. Therefore, this study examined whether bioelectrical impedance analysis (BIA) could be used to evaluate the nutritional status of patients with IBD.
Methods
We retrospectively analyzed data from 139 Korean patients with IBD who were treated between November 2018 and November 2019. Patients were categorized as having active or inactive IBD based on the Harvey-Bradshaw index (a score of ≥5 indicates active Crohn’s disease) and the partial Mayo scoring index (a score of ≥2 indicates active ulcerative colitis). BIA results and serum nutritional markers were analyzed according to disease activity.
Results
The mean patient age was 45.11±17.71 years. The study included 47 patients with ulcerative colitis and 92 patients with Crohn’s disease. Relative to the group with active disease (n=72), the group with inactive disease (n=67) had significantly higher values for hemoglobin (P<0.001), total protein (P<0.001), and albumin (P<0.001). Furthermore, the group with inactive disease had higher BIA values for body moisture (P=0.047), muscle mass (P=0.046), skeletal muscle mass (P=0.042), body mass index (P=0.027), and mineral content (P=0.034). Moreover, the serum nutritional markers were positively correlated with the BIA results.
Conclusions
Nutritional markers evaluated using BIA were correlated with serum nutritional markers and inversely correlated with disease activity. Therefore, we suggest that BIA may be a useful tool that can help existing nutritional tests monitor the nutritional status of IBD patients.

IBD
Vitamin D deficiency is associated with disease activity in patients with Crohn’s disease
Kyoung Ho Ko, You Sun Kim, Bo Kyung Lee, Jong Hyun Choi, Yong Moon Woo, Jin Young Kim, Jeong Seop Moon
Intest Res 2019;17(1):70-77.   Published online October 10, 2018

AbstractAbstract PDFPubReaderePub
Background/Aims
Previous data suggest that vitamin D has a significant role in inflammatory bowel disease (IBD). We investigated the incidence of vitamin D deficiency in Korean patients with IBD and the correlation between serum vitamin D level and disease activity.
Methods
We retrospectively analyzed the medical records of patients with IBD whose serum vitamin D levels were checked. Deficiency of 25-hydroxyvitamin D was defined as <20 ng/mL. Disease activity was evaluated using the partial Mayo score for ulcerative colitis (≥2 defined as active disease) and Harvey-Bradshaw index for Crohn’s disease (≥4 defined as active disease).
Results
We enrolled 87 patients with IBD (ulcerative colitis [UC], 45; Crohn’s disease [CD], 42). Among them, 65.5% (57/87) were men, with a mean age of 44.9±15.1 years (range, 18–75 years). The mean duration of disease was 4.7±4.8 years (range, 0.1–17.1 years). Vitamin D deficiency was found in 73.6% (64/87) of patients with IBD. Patients with IBD (mean vitamin D level, 16.3±9.0 ng/mL) showed lower vitamin D level than the healthy control group (mean vitamin D level, 20.4±7.0 ng/mL), with no statistically significant difference (P=0.136). Disease activity was inversely correlated with vitamin D deficiency in patients with CD (P=0.007). However, no correlation was observed in patients with UC (P=0.134).
Conclusions
Approximately 75% of Korean patients with IBD showed vitamin D deficiency state. Vitamin D deficiency is associated with disease activity, particularly in patients with CD.

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

The incidence and severity of Clostridium difficile infection (CDI) have increased worldwide, resulting in a need for rapid and accurate diagnostic methods.

Methods

A retrospective study was conducted to compare CDI diagnosis methods between January 2014 and December 2014. The stool samples, which were obtained in presumptive CDI patients, were compared for their diagnostic accuracy and rapidity, including real-time polymerase chain reaction (PCR) of toxin genes, C. difficile toxin assay, and culture for C. difficile.

Results

A total of 207 cases from 116 patients were enrolled in this study and 117 cases (56.5%) were diagnosed as having CDI. Among the 117 cases, the sensitivities of real-time PCR, C. difficile toxin assay, and culture for C. difficile were 87.2% (102 cases; 95% CI, 80.7%–92.8%), 48.7% (57 cases; 95% CI, 41.0%–59.8%), and 65.0% (76 cases; 95% CI, 60.2%–78.5%), respectively (P<0.005). Notably, 34 cases (29.0%) were diagnosed with CDI by real-time PCR only. The time required to obtain results was 2.27 hours (136.62±82.51 minutes) for real-time PCR, 83.67 hours (5,020.66±3,816.38 minutes) for toxin assay, and 105.79 hours (6,347.68±3,331.46 minutes) for culture (P<0.005), respectively.

Conclusions

We confirmed that real-time PCR of toxin genes is the most effective diagnostic method for accurate and early diagnosis of CDI. It also helps to diagnose hypervirulent CDI, such as ribotype 027 infection.

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

Among the many complications that can occur following therapeutic endoscopy, bleeding is the most serious, which occurs in 1.0-6.1% of all colonoscopic polypectomies. The aim of this study was to identify risk factors of delayed post-polypectomy bleeding (PPB).

Methods

We retrospectively reviewed the data of patients who underwent colonoscopic polypectomy between January 2003 and December 2012. We compared patients who experienced delayed PPB with those who did not. The control-to-patient ratio was 3:1. The clinical data analyzed included polyp size, number, location, and shape, patient' body mass index (BMI), preventive hemostasis, and endoscopist experience.

Results

Of 1,745 patients undergoing colonoscopic polypectomy, 21 (1.2%) experienced significant delayed PPB. We selected 63 age- and sex-matched controls. Multivariate logistic regression analysis showed that polyps >10 mm (odds ratio [OR], 2.605; 95% confidence interval [CI], 1.035-4.528; P=0.049), a pedunculated polyp (OR, 3.517; 95% CI, 1.428-7.176; P=0.045), a polyp located in the right hemicolon (OR, 3.10; 95% CI, 1.291-5.761; P=0.013), and a high BMI (OR, 3.681; 95% CI, 1.876-8.613; P=0.013) were significantly associated with delayed PPB.

Conclusions

Although delayed PPB is a rare event, more caution is needed during colonoscopic polypectomies performed in patients with high BMI or large polyps, pedunculated polyps, or polyps located in the right hemicolon.

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

Antibiotic usage and increasingly aging populations have led to increased incidence of Clostridium difficile infection (CDI) in worldwide. Recent studies in Korea have also reported increasing CDI incidence; however, there have been no reports on the long-term outcomes of CDI. We therefore investigated the long-term clinical outcomes of patients with CDI, including delayed recurrence, associated risk factors and mortality.

Methods

Hospitalized patients diagnosed with CDI at Seoul Paik Hospital between January 2007 and December 2008 were included. Their medical records were retrospectively investigated. 'Delayed recurrence' was defined as a relapse 8 weeks after a successful initial treatment. Multivariate logistic regression analysis was performed to identify risk factors for the delayed recurrence. Kaplan-Meier curves were used to analyze mortality rates.

Results

A total of 120 patients were enrolled; among them, 87 were followed-up for at least 1 year, with a mean follow-up period of 34.1±25.1 months. Delayed recurrence was observed in 17 patients (19.5%), and significant risk factors were age (over 70 years, P=0.049), nasogastric tube insertion (P=0.008), and proton pump inhibitor or H2-blocker treatments (P=0.028). The 12- and 24-month mortality rates were 24.6% and 32.5%, respectively. No deaths were directly attributed to CDI.

Conclusions

Delayed recurrence of CDI was not rare, occurring in 19.5% of the study population. Although CDI-related mortality was not reported, 2-year (32.5%) mortality rate of CDI patients implies that a CDI diagnosis may predict severe morbidity and poor prognosis of the underlying disease.

Intest Res 2014;12(1):74-77.   Published online January 28, 2014

AbstractAbstract PDFPubReader

Nearly 80% of patients with Crohn's disease (CD) require surgical treatment for complications or failure of medical management. We managed a 31-year-old man with CD who presented with a post-operative fistula. The patient had undergone surgery due to multiple strictures and a fistula. However, a new fistula developed that connected to the intraperitoneal abscess. Intravenous antibiotics were started and multiple percutaneous drainage tubes were inserted to treat the abdominal abscess. However, the amount of drainage was consistently high, even one month after the operation. To treat the postoperative fistula, 5 mg/kg of infliximab was started, and the amount of drainage decreased dramatically to less than 10 cc a day. Some studies have reported that infliximab decreases the recurrence of CD after surgery. The effect of infliximab on post-operative fistulas in patients with CD has not been sufficiently studied. Our results indicated that the use of infliximab to treat post-operative fistula should be explored further in future clinical studies.

AbstractAbstract PDF
Ulcerative colitis (UC) is one of the chronic inflammatory bowel diseases (IBD), characterized by a diffuse mucosal inflammation limited to the colon. Complications of UC include stricture, colorectal cancer, and toxic colitis. UC patients rarely present with a stenosis or fistula, and strictures develop in less than 5% of patients with UC. We present a patient with UC, accompanied by unusual complications that involved not only a stricture but also a fistula and abscess. A 49-year-old female was presented with a left flank pain and fever that had begun two weeks before admission. She had received a diagnosis of UC 20 years ago and had it treated for 2 years in a local hospital. However, she arbitrarily stopped visiting the hospital and relied on home remedies. An abdominopelvic CT scan revealed luminal narrowing and extra-peritoneal fistula formation in the descending colon. Fistula was connected with a subcutaneous abscess in the left flank. She had undergone total colectomy and ileo-anal anastomosis. On the pathologic exam, the long standing UC with severe stenosis was observed without malignant change. It cannot be emphasized enough that a correct therapeutic approach and an appropriate follow-up schedule are very important for patients with UC. (Intest Res 2012;10:388-391)

Clinical Significance of Erosive or Ulcerative Lesions Isolated in Terminal Ileum
Sun Ok Kwon, You Sun Kim, Myoung Ki Oh, Sun Young Kim, In Hye Cha, Seong Yeon Jeong, Joo Yeon Cho, Jin Nam Kim, Jeong Seop Moon
Intest Res 2012;10(4):350-356.   Published online October 31, 2012
DOI: https://doi.org/10.5217/ir.2012.10.4.350
AbstractAbstract PDF
Background/Aims
Although terminal ileal erosive or ulcerative lesions are frequently observed on colonoscopic examination, their clinical significance are unclear. We evaluated clinical course and significance of isolated terminal ileal erosive or ulcerative lesions. Methods: We retrospectively analyzed clinical features, number, size and histologic findings of 186 patients with isolated terminal ileal erosive or ulcerative lesions on colonoscopic examination from December 2003 to February 2012. Results: The indications for colonoscopy included screening for colorectal cancer or surveillance in 122 patients (65.6%), evaluations for symptoms in 64 patients (34.4%). Of the 186 patients, 170 underwent biopsy at the terminal ileal lesions. Histologic findings were mostly non-specific chronic inflammation except two cases of Crohn's disease, one case of cytomegalovirus ileitis, and one case of intestinal tuberculosis. Forty six patients underwent follow-up colonoscopy and the mean duration was 17.8±14.2 months (range, 1-64 months). Of those who showed non-specific ileitis (44 patients), 35 (79.5%) showed resolution of lesions without specific treatment. In the remaining 9 (20.5%) patients, lesions were continued and two patients were diagnosed as Crohn's disease and Behcet's ileitis, respectively. There were no significant differences in the duration of follow-up, presence of symptoms, number and size of terminal ileal lesions between the patients who resolved and not resolved. Conclusions: Most isolated terminal ileal erosive or ulcerative lesions reveal non-specific histological findings and have a propensity to resolve without treatment. However, in small portions of patients, isolated terminal ileal lesions need careful attention because it is possible to be early inflammatory bowel diseases. (Intest Res 2012;10:350-356)

Intest Res 2008;6(2):110-115.   Published online December 30, 2008
AbstractAbstract PDF
Background/Aims
Although colonic diverticular disease is less common in Koreans than in Western people, its incidence has been on the increase in Korea. We investigated the clinical characteristics and related complications of colonic diverticular disease in Koreans. Methods: We retrospectively reviewed the medical records of 9,006 patients who underwent colonoscopy at the Seoul Paik hospital between July 2002 and January 2008. Results: Of the 9,006 patients, there were 654 cases (7.3%) of colonic diverticulosis (472 men, 182 women). The mean age of the patients was 54.6±12.0 years. The right colon was involved in 535 cases, the left colon was involved in 86 cases and both the left and right colon was involved in 33 cases. Among the patients, a single diverticulum was seen in 253 cases and two or more diverticuli were seen in 401 cases. Related complications were diverticulitis (11 cases, 1.7%) and diverticular bleeding (3 cases, 0.5%). Conclusions: The incidence of colonic diverticular disease in Korea shows an increasing trend. Colonic diverticular lesions are frequently found in the right colon. (Intest Res 2008;6:110-115)

Clinical Value of Endoscopic Resection of Large Colonic PolypsUsing a Detachable Snare
Jin Gook Huh, You Sun Kim, Sun Ok Kwon, Won Cheol Jang, Kyung Sun Ok, Tae Yeob Jeong, Soo Hyung Rye, Jung Hwan Lee, Jeong Seop Moon
Intest Res 2007;5(2):151-157.   Published online December 30, 2007
AbstractAbstract PDF
Background/Aims
A large colonic polyp is a challenge for endoscopists due to the risk of serious hemorrhage, perforation or incomplete resection. We examined whether endoscopic resection of large polyps using a detachable snare is a feasible and safe procedure. We also examined the sizes of a polyp that could be removed. Methods: We retrospectively reviewed 65 cases of endoscopic resection of large colonic polyps using a detachable snare. Results: The sizes of the polyps included 3.5 cm (n=3), 3.0 to 3.4 cm (n=8), 2.0 to 2.9 cm (n=16) and 1.0 to 1.9 cm (n=38). The mean polyp size was 1.8 cm. The pathologic diagnoses of the resected polyps included 20 adenocarcinomas (30.8%), 38 adenomas (58.5%), three hyperplastic polyps, two inflammatory polyps, one hamartomatous polyp and one lymphangioma. The complete resection rate was 98.5% (64/65). There were no complications such as perforation, delayed bleeding or the need for additional surgery. Six complications of immediate bleeding (9.2%) developed after resection, but the bleeding was easily controlled by endoscopic treatment. Conclusions: According to our study, endoscopic resection of large polyps using a detachable snare can reduce not only complications of bleeding but also incomplete resection. Therefore, polyp size alone is rarely a contraindication to the endoscopic resection of a colonic polyp. (Intest Res 2007;5:151-157)

Comparative Value of Sigmoidoscopy and Stool Cytotoxin-A Assay for Diagnosis of Pseudomembranous Colitis
Jin Kwang Lee, Joo Yeon Cho, You Sun Kim, Seong Eun Kim, Soo Hyung Ryu, Jung Whan Lee, Jeong Seop Moon
Intest Res 2005;3(1):61-67.   Published online June 30, 2005
AbstractAbstract PDF
Background/Aims
Stool cytotoxin-A assay has been used clinically and commonly for diagnosis of C. difficile associated diarrhea (CDAD). However, the incidence and severity of CDAD show increasing tendency with frequent use of antibiotics, rapid diagnosis is required for severe CDAD. Therefore, we compared diagnostic value of sigmoidoscopy with that of stool cytotoxin-A assay for diagnosis of pseudomembranous colitis (PMC). Methods: During the period from April 2004 to April 2005, a total of 28 cases of suspected CDAD were analyzed prospectively. Both flexible sigmoidoscopy and enzyme immunoassay for stool cytotoxin-A assay were performed and compared with diagnostic yield. The clinical manifestation and used antibiotics were analyzed. Results: The PMC was developed frequently in old age and had clinical symptoms such as diarrhea, abdominal pain and mild fever. The diagnostic yield of stool cytotoxin-A assay was 36.8% while the sigmoidoscopy was 73.6% without significance. With the stool cytotoxin-A assay, the diagnosis for CDAD including PMC was delayed to mean 4.7 days. Conclusions: With increasing use of antibiotics, the incidence and severity of CDAD were increasing. The rapid diagnosis by sigmoidoscopy is more helpful to management of severe CDAD such as PMC than stool cytotoxin-A assay. (Intest Res 2005;3:61-67)
