The Use of Gabexate Mesylate and Ulinastatin for the Prevention of Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis

BACKGROUND/AIMS: Acute pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography (ERCP). Only a few pharmacologic agents have been shown to have potential efficacy for the prophylactic treatment of post-ERCP pancreatitis (PEP). The aim of this study was to determine whether prophylactic gabexate and ulinastatin can decrease the incidence of PEP. METHODS: From January 2005 to April 2010, 1,679 patients undergoing ERCP treatment were consecutively enrolled in the study. After selective exclusion, a total of 1,480 patients were included in the analysis. The patients were separated into 3 groups according to the prophylactic administration of gabexate (593 patients), ulinastatin (229 patients), or saline solution (658 patients) and analyzed retrospectively. The primary outcome measurements were the incidence of pancreatitis and hyperamylasemia. RESULTS: PEP occurred in 21 of the 593 (3.5%) patients who received gabexate, 16 of the 229 (7.0%) patients who received ulinastatin, and 48 of the 658 (7.3%) patients who received a saline solution. The incidence of PEP was significantly different between the gabexate and ulinastatin or saline solution groups (p<0.05). CONCLUSIONS: Gabexate prophylaxis is effective in preventing PEP. However, there is no difference in the beneficial effects of the prophylactic administration of ulinastatin and a saline solution.

A Case of Barium Appendicitis after a Small Bowel Series / 대한소화기내시경학회지

Barium appendicitis is a rare complication that occurs due to barium retention in the appendix after a barium study. It is believed that retained barium in the appendix forms a barium-coated fecalith and causes barium appendicitis. A 19-year-old man visited the hospital due to melena. He underwent an endoscopy and a colonoscopy but no bleeding focus was discovered. Next, a small bowel series was performed to confirm the absence of small bowel bleeding. Two weeks later, he felt right lower quadrant pain in his abdomen and developed a fever. A blood test revealed an elevated white blood cell count. A plain abdominal radiograph indicated retained barium in the appendix. A computed tomography scan revealed a dilated barium filled appendix. Thus, the pain was thought to caused by barium retention in the appendix that precipitated acute appendicitis. He underwent an appendectomy and healed well without complications.

Polymorphism of IL-1beta; IL-1Ra, TNF-alpha Cytokine Genes in Korean Patients with Glomerulonephritis / 대한신장학회잡지

BACKGOUND: Recently it has been reported that several cytokine gene polymorphisms regulate cytokine production and play an important role in immune and inflammatory response. We evaluated IL-1beta IL-1Ra, and TNF-alpha gene polymorphism in patients with primary glomerulonephritis to determine the association between cytokine polymorphism and disease susceptibility. METHODS: In this study, we enrolled 118 patients with primary glomerulonephritis and healthy 300 persons who had visited the health screening center. We analyzed -511C/T polymorphism of IL-1beta tandem repeats polymorphism in intron 2 of IL-1Ra and -308G/A polymorphism of TNF-alpha We classified primary glomerulonephritis according to pathologic finding and clinical diagnosis. RESULTS: There were no differences with IL-1betaand TNF-alpha gene polymorphism between patient and control group. The carriage of IL1RN*2 was significantly associated with an increased risk of primary glomerulonephritis (patients:control=12.75:5.4%, p<0.01). IL1RN*2 was significantly frequent in patients with membranous GN or minimal change disease (p<0.05). When we classified glomerulonephritis according to clinical diagnosis, IL1RN*2 carriage rate was higher in patients with nephrotic syndrome and RPGN or acute nephritic syndrome than patients with asymptomatic urinary abnormalities (p<0.05). IL-1beta(TT) genotype was more prevalent in acute glomerulonephritis (68.4%) than asymptomatic urinary abnormalities or other glomerulonephritis. TNF2 carriage rate showed a lower tendency in patients with asymptomatic urinary abnormalities. CONCLUSION: IL1RN*2 is significantly associated with an increased risk of development of primary glomerulonephritis. We suggest cytokine gene polymorphism is also related to clinical manifestations of glumerulonephritis.
