Pulmonary complications of ulcerative colitis are relatively uncommon and may present as a variety of disorders. Ulcerative colitis-related interstitial lung disease is extremely rare. There are a few case reports of nonspecific interstitial pneumonia in ulcerative colitis worldwide but none in Korea. We report a patient with ulcerative colitis related biopsy-proven nonspecific interstitial pneumonia, who responded to prednisolone (1 mg/kg) and mesalazine therapy.

Ulcerative colitis is a disease that causes inflammation in the mucosal or submucosal layer of the colon. Previous studies have reported that obesity increases the prevalence of ulcerative colitis and aggravates the progression. This study was therefore undertaken to investigate whether curcumin inhibits the progression of ulcerative colitis caused by obesity. Mice were bred on a high-fat diet to induce obesity, and curcumin was administered with the high-fat diet to confirm the anti-inflammatory effect. To induce ulcerative colitis, dextran sulfate sodium (DSS) was administered orally, and clinical symptoms of colitis were subsequently observed. For histological evaluation of curcumin, the colon, liver and abdominal fat tissue samples were prepared and analyzed by hematoxylin and eosin (H&E) and Alcian blue-periodic acid-Schiff (PAS) staining. Our results confirm that consumption of curcumin resulted in decreasing the score of the disease activity index, and inhibited shortening of the colon length. In addition, inflammatory cell infiltration and mucosal damage were inhibited in the colon tissue of ulcerative colitis exacerbated by obesity. We further confirmed that exposure to curcumin significantly reduced the steatosis area of the liver and adipocytes of abdominal fat. In conclusion, we believe that curcumin can be applied as a therapeutic agent to treat ulcerative colitis, by inhibiting the progression of colitis caused by obesity.

Paeoniae Radix has been used as a traditional medicine for various diseases including hepatic disease. However, the inhibitory effect of Paeoniae Radix on intestinal inflammation has not been fully understood yet. The aim of this study was to evaluate the effect of Paeoniae Radix on colitis induced by dextran sulfate sodium in mice. To investigate the protective effects of Paeoniae Radix, the colitis mice were induced by drinking water containing 5% dextran sulfate sodium for 7 days. Mice were randomized into groups receiving Paeoniae Radix (100 mg/kg), sulfasalazine (150 mg/kg) as a positive control, or water as a negative control. We evaluated the effects of Paeoniae Radix on clinical signs induced by dextran sulfate sodium, measuring weight loss, colon length, and disease activity index. Additionally, to find a possible explanation for the anti-inflammatory effects of Paeoniae Radix, we evaluated the effects of Paeoniae Radix on the interleukin-6 and cyclooxygenase-2 levels in colitis tissue. The results indicated that mice treated with dextran sulfate sodium showed measurable clinical signs, including weight loss and reduced colon length. However, Paeoniae Radix treatment significantly improved the weight loss and disease activity index as clinical symptoms. Moreover, Paeoniae Radix inhibited the interleukin-6 and cyclooxygenase-2 expression levels in colon tissues treated with dextran sulfate sodium. Taken together, the findings of this study suggest that Paeoniae Radix may be useful for treating intestinal inflammation, including ulcerative colitis.

Extracolonic manifestations which occur in approximately 10~20% of patients with ulcerative colitis most commonly affect joints, skin, liver and eyes. In contrast, pulmonary involvement in ulcerative colitis is very rare. However, a variety of respiratory disorders has been associated with ulcerative colitis, including pulmonary vasculitis, bronchiectasis, chronic bronchitis, interstitial fibrosis, pleural effusion. Since the first observation of pulmonary involvement in ulcerative colitis by Kraft in 1976, a few cases have been reported, and probably no such case have been reported in Korea yet. Here we report an experience concerning 56 year-old man interstitial lung disease in ulcerative colitis, who was diagnosed by clinical, radiographic, endoscopic, histologic findings.

Patients with inflammatory bowel disease are known to have hypercoagulability and an increased risk for venous thromboembolism. The deep veins of the lower extremities and the pulmonary veins are the most common sites of thrombosis in ulcerative colitis. However, hepatic vein thrombosis (Budd-Chiari syndrome) is a very rare extra-intestinal complication of ulcerative colitis in children. We describe a case of hepatic vein thrombosis in a 15-year-old girl with ulcerative colitis who presented with abdominal pain and hematochezia. Doppler ultrasonography and an abdominal CT scan revealed the characteristic filling defects caused by large thrombi in both hepatic veins. These lesions were successfully treated with conventional management for ulcerative colitis and anticoagulation therapy.

The two main types of inflammatory bowel disease (IBD) are Crohn's disease and ulcerative colitis. Currently, when IBD is suspected, CT enterography is widely used as an initial imaging test because it can evaluate both the bowel wall and the outside of the bowel, helping to differentiate IBD from other diseases. When IBD is suspected, it is necessary to distinguish between Crohn's disease and ulcerative colitis. In most cases this is not difficult; however, in some cases, it is difficult and such cases are called IBD-unclassified. CT findings are often non-specific for ulcerative colitis, making it difficult to differentiate it from other diseases using imaging alone. In contrast, characteristic CT findings for Crohn's disease are often helpful in diagnosis, although diseases, such as tuberculous enteritis can mimic Crohn's disease. Recently, mutations in the gene encoding a prostaglandin transporter called SLCO2A1 have been discovered as the cause of the disease in some patients with multiple ulcers and strictures, similar to Crohn's disease. Therefore, genetic testing is being used to make a differential diagnosis.

Purpose: Colitis is a condition associated with a spectrum of altered morphologic changes and cellular adhesion. E-cadherin plays a key role in the establishment and maintenance of epithelial tissue structure and cell-cell adhesion. The purpose of this study is to evaluate E-cadherin expression in colonic epithelium of various colitis in children. Methods: The expressions of E-cadherin were examined in 39 cases of colonic mucosal biopsy specimen using immunohistochemical staining. When more than 50 percent of cells exhibited uniformly the same intensity and pattern of immunostaining as the adjacent normal mucosa, the antigen expression was considered normal. Abnormal expression was defined when less than 50 percent of cells stained, when cells showed a heterogeneously weak or altered distribution, or when complete absence of staining was observed. Results: Fifteen cases with non-specific colitis (38.5%), 7 cases of with Crohn's disease (17.9%), 5 cases of infectious colitis and milk protein sensitive proctocolitis (12.8%), 3 cases of ulcerative colitis (7.7%), 2 cases of Henoch-Schonlein purpura colitis (5.1%), one case of Behcet's disease and ischemic colitis (2.6%) were included in this study. E-cadherin expression was decreased in all kinds of colitis. Reduced expression of E-cadherin was observed in 77 percent of cases. E-cadherin was weaker or no expression in reparative epithelium and "ulcer associated cell lineage". Conclusion: Altered expression of E-cadherin occurs during mucosal inflammation in any kinds of colitis. These changes may be involved in promoting cell migration during epithelial restitution of the gastrointestinal mucosa.

Objectives: This study analyzes domestic research trends on herbal medicine treatments for ulcerative colitis (UC) by examining 28 selected domestic papers using the Oriental Medicine Advanced Searching System (OASIS) as the main search source. Methods: A total of 28 domestic papers were selected on the OASIS platform as the main search source using the keywords "(궤양성 대장염) or (궤양성 대장병)" and "(한약) or (한의학)". Results: There were 11 case report studies and 17 case-control studies published from 2002 to 2022. All the case-control studies only dealt with mice and did not include human subjects. The most common pathologies were damp heat and Changpung. Hwangryunhaedok-tang was the most frequently prescribed herbal formula, and Coptidis Rhizoma was the most commonly used herb across all studies. The results showed that many studies demonstrated the significant effects of herbal treatment. Conclusion: Herbal medicine may exhibit therapeutic effects on various aspects of UC. However, evidence-based studies, such as clinical trials involving human subjects, are needed.

Autoimmune hepatitis (AIH), primary sclerosing cholangitis (PSC), and primary biliary cirrhosis (PBC) are chronic autoimmune liver diseases. Overlap syndrome is defined as a condition in which the clinical, biochemical, and histological features of these autoimmune diseases are overlapped. Thus, it is difficult to appreciate overlap syndrome as an actual diagnostic entity. Only a few cases of the overlap syndrome of AIH and PSC have been reported, especially in children. Moreover, PSC is known to be the most frequent liver disorder associated with inflammatory bowel diseases such as ulcerative colitis. We report one case of AIH-PSC overlap syndrome in a child who was diagnosed as having ulcerative colitis.

Intractable ulcerating enterocolitis is an uncommon inflammatory bowel disease syndrome of neonatal onset first described in 1991. Intractable ulcerating enterocolitis usually presents in the neonate with a mouth ulceration and the subsequent development of perianal disease and colitis. In this case report, an infant, 18 days from birth, with ulcerative lesion on hard palate for systemic differential diagnosis about oral lesion is referred from the department depiatrics. At that time, there is no abnormality, except oral lesion-like Aphthous ulcer. The patient was discharged from pediatrics, but returned to the hospital 3weeks later with blood diarrhea. As a result of endoscopy, there were large ulcerating lesions and the patient was diagnosed intractable ulcerating enterocolitis. Early recognition of Intractable ulcerating enterocolitis appears to be beneficial because colectomy, as opposed to immunosuppression, appears to be effective in controlling disease symptoms and progression. Most of the infants who were affected intractable ulcerating enterocolitis were normal at birth and oral manifestation appeared earlier than others. So, it is very meaningful for dentists to know about Intractable ulcerating enterocolitis.
