A Case of Systemic Lupus Erythematosus Manifesting First as Mesenteric Vasculitis: Gun Hwa Lee, Chang Soo Eun, June Seok Song, Il Hwan Oh, Suk Hyun Jung, Hye Sun Park, Yong Chul Jun, Ju Hyun Sohn, Dong Soo Han; Intest Res 2012;10(3):305-308.

Abstract PDF: Systemic lupus erythematosus (SLE) is a multisystem inflammatory disease that manifests various symptoms. Mesenteric vasculitis (MV) is one of the serious complications of SLE and carries a high mortality rate. Although MV is the main cause for acute abdominal pain in patients with SLE, it is very rare for the pain to be the first clinical manifestation of the disease. A 34-year old female presented with sudden onset abdominal pain accompanied by small intestinal bowel edema observed on abdominal computed tomography. We performed a diagnostic laparoscopy, as vital signs were becoming unstable and the diffuse abdominal tenderness was worsening rapidly. The examination showed a severe jejunal infarction; thus, the patient underwent a small bowel segmental resection. A histological examination revealed multiple, hemorrhagic, small-vessel vasculitis, and later serologic autoimmune markers were consistent with SLE. We suggest that SLE be considered in the differential diagnosis of young females presenting with an acute abdomen and unexplained enteropathy. A surgical approach such as exploratory laparoscopy could be an option in search for the cause. (Intest Res 2012;10: 0-308)

A Case of Methicillin-Resistant Staphylococcal Enterocolitis with Subsequent Development of Lymphocytic Colitis: Joong Ho Bae, Dong Soo Han, Hye Sun Park, Yil Sik Hyun, Tae Yeob Kim, Chang Soo Eun, Yong Cheol Jeon, Joo Hyun Sohn; Intest Res 2011;9(2):139-143.

Abstract PDF: Staphylococcus aureus (S. aureus) is occasionally a normal inhabitant of the gastrointestinal tract, and rarely considered a cause of enterocolitis. Methicillin-resistant Staphylococcal enterocolitis may cause persistent diarrhea leading to severe complications and even death, without appropriate treatment. Lymphocytic colitis (LC), a subtype of microscopic colitis, is a relatively common cause of chronic watery diarrhea. We report the case of a 73-year-old woman with profuse watery diarrhea caused by methicillin-resistant S. aureus. Soon after treatment of her enterocolitis with vancomycin the patient's general condition and symptoms improved, although the diarrhea persisted. Through colonoscopic biopsy and immunohistochemical staining, overt LC was diagnosed, and prompt therapy with budesonide was initiated. (Intest Res 2011;9:139-143)

A Case of Hepatosplenic T-cell Lymphoma with Colonic Involvement: Ji Young Choi, Hye Sun Park, Dong Soo Han, Jae Hoon Kim, Yil Sik Hyun, Joong Ho Bae, Chang Soo Eun, Young Ha Oh; Intest Res 2011;9(1):51-55. Published online April 30, 2011; DOI: https://doi.org/10.5217/ir.2011.9.1.51

Abstract PDF

Hepatosplenic T-cell lymphoma is a rare histologic type of peripheral T-cell lymphoma that usually presents with hepatosplenomegaly, B-symptoms, and often with rapid and aggressive progression. There have been no previous domestic reports of a hepatosplenic T-cell lymphoma involving the colon. We report a case of a 61-year old man with colonic invasion of a hepatosplenic T-cell lymphoma. He presented the sudden onset of fever accompanied by severe pancytopenia and rapid liver enzyme elevation without evidence of lymphadenopathy. Multiple tiny erosions were noted during colonoscopy. In addition, many immature lymphocytes with vague nucleoli, abundant eosinophilic cytosol, and nuclei of small-to-medium size were seen within the sinusoids on liver biopsy. A similar pattern existed on colonic mucosa obtained from colonoscopic biopsy. Thus, with the aid of such a specific clinical presentation and the results of immunohistochemical staining, we made a definitive diagnosis of hepatosplenic T-cell lymphoma with colonic involvement.

Postinfectious Irritable Bowel Syndrome after Clostridium difficile Infection: Hye Sun Park, Dong Soo Han, Yil Sik Hyun, Joong Ho Bae, Sang Bong Ahn, Hyun Seok Cho, Tae Yeob Kim, Chang Soo Eun, Yong Cheol Jeon, Joo Hyun Sohn; Intest Res 2009;7(2):100-104. Published online December 30, 2009

Abstract PDF: Background/Aims
Post-infectious irritable bowel syndrome (PI-IBS) frequently follows bacterial enterocolitis, and there are various reported incidences and clinical courses according to different pathogens. However, there have rarely been any reports regarding the PI-IBS caused by Clostridium difficile infection (CDI). The aims of this study were to evaluate the incidence and the risk factors for developing IBS following CDI. Methods: We recruited 86 patients with CDI from January 2005 to October 2007 and also we recruited a comparative control group of 86 patients who had no previous history of any gastroenterological disease. The bowel symptoms were prospectively evaluated by phone through a set questionnaire. Results: Of all the CDI patients, a total of 41 patients (47.6%) completed the questionnaires, and IBS developed in 8 patients (19.5%), of which 7 patients (87.5%) were the diarrhea type. A total of 51 patients (59.3%) from the control group completed the questionnaires, of which 4 patients (7.8%) developed IBS. Although there was no statistically significant difference (p=0.099), there was a tendency towards a higher incidence of developing IBS in the CDI patients group, as compared to that of the control group. Comparing the group that developed IBS with the group that didn't among the CDI patients, there were no significantly different factors except for a previous admission history before CDI. Conclusions: The incidence of PI-IBS after CDI was 19.5%, and the IBS was predominantly the diarrhea-type. In the future, a large scale study needs to be conducted in order to evaluate the PI-IBS incidence after CDI and the risk factors that predispose patients to such conditions.
