류마티스관절염 환자의 혈청 내 항GPI 항체의 임상적 의의
변유미 ( Yu Mi Byeon ),김상현 ( Sang Hyon Kim ),박성환 ( Sung Hwan Park ) 대한류마티스학회 2007 대한류마티스학회지 Vol.14 No.4
Objective: Anti-glucose-6-phosphate isomerase (GPI) antibody (Ab) is known to be arthritogenic in K/BxN mice. Anti-GPI Ab is present in some patients with rheumatoid arthritis (RA), but their clinical manifestations are not clearly elucidated. The purpose of this study was to evaluate whether GPI serves as a specific autoantigen in patients with RA and to investigate the relationship of anti-GPI Ab with clinical parameters of RA. Methods: Sera were collected from 54 patients with RA, 15 patients with osteoarthritis (OA) and 28 healthy controls. The samples were tested by enzyme-linked immunosorbent assay (ELISA) using human recombinant GPI as antigen. Patients with RA were classified according to rheumatoid factor (RF) positivity, the presence of RA shared epitope (SE), the presence of extraarticular manifestations, and evidence of bony erosive changes. Results: Serum levels of anti-GPI Ab were higher in patients with RA than controls (1599.46±1022.48 versus 344.82±223.16 AU, p<0.001), and the levels of patients with OA were also higher than controls (1161.47±917.44 versus 344.82±223.16 AU, p<0.01). In RA, there were no significant difference in anti-GPI Ab levels according to RF positivity, the presence of RA SE, the presence of extraarticular manifestations, and evidence of bony erosive changes. Conclusion: Our results suggest that anti-GPI Ab may not be RA specific Ab and not related to the severity of RA.

구토 후 발생한 토혈을 주소로 내원한 환자에서 좌측 늑막 삼출 동반 시 식도 파열의 가능성을 고려하여 흉수 천자 및 지속적인 흉부 단순 촬영의 추적관찰이 필요하며 식도 파열이 배제된 후 환자의 생체 징후 및 토혈 양을 파악하여 내시경 검사 시기를 신중히 결정하는 것이 좋을 것으로 생각된다. 본 증례는 토혈을 주소로 내원하여 Mallory-Weiss 증후군 의심 하에 내시경을 통한 치료 시행 후 추적 관찰에 의해 진단된 Boerhaave 증후군을 경험하였기에 보고하는 바이다. Boerhaave's syndrome is a spontaneous perforation of the esophagus most commonly resulting from a sudden increase in intraesophageal pressure combined with negative intrathoracic pressure caused by straining or vomiting. Surgery should generally be performed within 24 hours because mortality approached 30 to 50 percent in which surgery was delayed. Therefore, early diagnosis and prompt surgical repair are critical for survival. We have experienced a case of Boerhaave's syndrome in a patient presenting with hematemesis with left pleural effusion without any signs or symptoms of pneumomediastinum or pneumothorax.

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening syndrome characterized by the classic pentad of clinical features that includes microangiopathic hemolytic anemia, thrombocytopenia, neurologic abnormalities, fever, and renal dysfunction. Early diagnosis and utilization of plasmapheresis can improve the survival rates of patients with TTP. TTP rarely may be seen in association with autoimmune disease such as systemic lupus erythematous (SLE). We report here a 42-year-old female who was presented with severe digital gangrenes, microangiopathic hemolytic anemia, thrombocytopenia, neurologic abnormalities, fever, and renal dysfunction. Her condition responded to combined therapy with high dose steroid, immunosuppressants, and plasmapheresis therapy.

제 1형 신경섬유종증 환자에서 발생한 위장관 간질종양 1예

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

간경변 환자에서 Oro-cecal Transit Time의 측정
원경준,이준,변유미,조민근,조주연,서정균,김영대,박찬국,김만우 朝鮮大學校 附設 醫學硏究所 2008 The Medical Journal of Chosun University Vol.33 No.2
Background: Neurotransmitter like substances in the gut have been proposed to contribute to the overall portal systemic encephalopathy (PSE). The source of the ammonia in patients with PSE is mainly the small bowel, as a result of the conversion of glutamine in the diet to glutamate and ammonia. PSE is highly responsive to changes in diet, to antibiotic therapy and to ingestion of nondigestible disaccharides such as lactulose. This study was performed to evaluate the relationship between PSE and oro-cecal transit time. In addition, performed to evaluate the effect of severity, cause, complications of liver cirrhosis on oro-cecal transit time. Methods: Between August 2006 and February 2007, 48 cirrhotic patients consecutively was enrolled in study their oro-cecal transit time after informed consent was obtained. A non-invasive hydrogen breath test was used to study oro-cecal transit time (OCTT). Result: The OCTT were delayed in cirrhotic patients with PSE compared without PSE (123.3 ± 42.7 min vs 170.0 ± 58.3 min, p<0.05). OCTT tended to prolongate further as the damage in the liver got worse, nevertheless the result was statistically meaningless (p<0.111). Neither presence of ascites or cause of PSE had any influence on gastrointestinal transit. Conclusions: Cirrhotic patients with PSE have more delayed OCTT than without PSE. Further research is needed to find out the relationship between OCTT and severity of liver cirrhosis.

아메바성 대장염과 연관된 Henoch-Scho¨nlein Purpura 1예
장재현,원경준,이준,변유미,이재광,김영훈,박찬국,김만우 朝鮮大學校 附設 醫學硏究所 2006 The Medical Journal of Chosun University Vol.31 No.3
Henoch-SchonIein purpura is a common form of vasculitis primarily involving the skin, the gastrointestinal tract, the joints, the kidneys, and the nervous system. The etiological investigations are essential, because triggering factors are found in approximately half the patients such as viral, bacterial and parasitic infections, drugs, toxins, systemic diseases and cancer. But it's the correlation between Henoch-SchonIein purpura and Entamoeba histolytica has been rarely reported. We report a 29-years-old woman with Henoch-SchoIein purpura complicated by the lower gastrointestinal bleeding caused by the amoebic colitis. She complained of cramping abdominal pain, lower extremity purpura and hematochezia. Cysts and trophozoites of Entamoeba histolytica were detected in her stool. Skin biopsy demonstrated the leukocytoclastic vasculitis. She was administered metronidazole 1,500㎎ a day for the treatment of amebic colitis. Her hematochezia was improved, but the abdominal pain and purpura were not. The subsequent corticosteroid therapy improved her symptoms.
