| 1 | Immunoglobulin G4-related gastrointestinal diseases, are they immunoglobulin G4-related diseases?显示文摘In immunoglobulin G4(IgG4)-related disease(RD),organ enlargement or nodular lesions consisting of abundant infiltration of lymphocytes and IgG4-positive plasma cells and fibrosis are seen in various organs.Although infiltration of many IgG4-positive plasma cells is detected in the gastric and colonic mucosa and major duodenal papilla of patients with autoimmune pancreatitis,it cannot be diagnosed as a gastrointestinal lesion involved in IgG4-RD,because none of the following is observed in these lesions:a mass-like formation;dense fibrosis;or obliterative phlebitis.Based on our review of the literature,there appear to be two types of IgG4-related gastrointestinal disease.One is a gastrointestinal lesion showing marked thickening of the wall of the esophagus and stomach,consisting of dense fibrosis with abundant infiltration of IgG4-positive plasma cells,which usually show submucosal spreading.The other is an IgG4-related pseudotumor occurring in gastrointestinal regions such as the stomach,colon,and major duodenal papilla,showing polypoid or mass-like lesions.Most solitary IgG4-related gastrointestinal lesions that are not associated with other IgG4-RD appear to be difficult to diagnose.It is of utmost importance to rule out malignancy.However,these lesions may respond to steroid therapy.To avoid unnecessary resection,IgG4-related gastrointestinal diseases should be considered in the differential diagnosis. | Satomi Koizumi Terumi Kamisawa Sawako Kuruma Taku Tabata Kazuro Chiba Susumu Iwasaki Yuka Endo Go Kuwata Koichi Koizumi Tooru Shimosegawa Kazuichi Okazaki Tsutomu Chiba | 2013 | World Journal of Gastroenterology2013，19，35： | 12 |
| 2 | Pegylated interferon plus ribavirin for genotype Ib chronic hepatitis C in Japan显示文摘AIM:To evaluate the efficacy of pegylated interferon α-2b(peg-IFNα-2b) plus ribavirin(RBV) therapy in Japanese patients with chronic hepatitis C(CHC) genotype Ib and a high viral load.METHODS:One hundred and twenty CHC patients(58.3% male) who received peg-IFNα-2b plus RBV therapy for 48 wk were enrolled.Sustained virological response(SVR) and clinical parameters were evaluated.RESULTS:One hundred(83.3%) of 120 patients completed 48 wk of treatment.53 patients(44.3%) achieved SVR.Early virological response(EVR) and end of treatment response(ETR) rates were 50% and 73.3%,respectively.The clinical parameters(SVR vs non-SVR) associated with SVR,ALT(108.4 IU/L vs 74.5 IU/L,P = 0.063),EVR(76.4% vs 16.4%,P < 0.0001),adherence to peg-IFN(≥ 80% of planned dose) at week 12(48.1% vs 13.6%,P = 0.00036),adherence to peg-IFN at week 48(54.7% vs 16.2%,P < 0.0001) and adherence to RBV at week 48(56.1% vs 32.1%,P = 0.0102) were determined using univariate analysis,and EVR and adherence to peg-IFN at week 48 were determined using multivariate analysis.In the older patient group(> 56 years),SVR in females was significantly lower than that in males(17% vs 50%,P = 0.0262).EVR and adherence to Peg-IFN were demonstrated to be the main factors associated with SVR.CONCLUSION:Peg-IFNα-2b plus RBV combination therapy demonstrated good tolerability in Japanese patients with CHC and resulted in a SVR rate of 44.3%.Treatment of elderly female patients is still challenging and maintenance of adherence to peg-IFNα-2b is important in improving the SVR rate. | Takayuki Kogure Yoshiyuki Ueno Koji Fukushima Futoshi Nagasaki Yasuteru Kondo Jun Inoue Yasunori Matsuda Eiji Kakazu Takeshi Yamamoto Hiroyoshi Onodera Yutaka Miyazaki Hiromasa Okamoto Takehiro Akahane Tomoo Kobayashi Yutaka Mano Takao Iwasaki Motoyasu Ishii Tooru Shimosegawa | 2008 | World Journal of Gastroenterology2008，14，47： | 7 |
| 3 | Fulminant hepatic failure in a case of autoimmune hepatitis in hepatitis C during peg-interferon-alpha 2b plus ribavirin treatment显示文摘A 27-year-old Caucasian female with hepatitis C virus (HCV) infection treated with interferon (IFN) who developed severe autoimmune hepatitis (AIH) is described. The infecting viral strain was of genotype Ib and the pre-treatment HCV viral load was at a high level. The patient was treated with pegylated IFN-alpha 2b and ribavirin,and her HCV-RNA became negative at wk 12,but after that she developed fulminant hepatic failure. The patient recovered after steroid pulse therapy consisting of methylprednisolone 1000 mg/d for three days which was administered twice. A needle liver biopsy revealed the typical pathological findings of AIH. | Takayuki Kogure Yoshiyuki Ueno Koji Fukushima Futoshi Nagasaki Jun Inoue Eiji Kakazu Yasunori Matsuda Osamu Kido Yu Nakagome Osamu Kimura Noriyuki Obara Yuta Wakui Takao Iwasaki Tooru Shimosegawa | 2007 | World Journal of Gastroenterology2007，13，32： | 5 |

| 5 | Liver cell adenoma showing sequential alteration of radiological findings suggestive of well-differentiated hepatocellular carcinoma显示文摘A liver tumor 35 mm in diameter was found incidentally in a 40-year-old woman who had no history of liver diseases or the use of oral contraceptives.Radiological diagnostics showed the typical findings of liver cell adenoma(LCA).Dynamic computed tomography revealed that the tumor showed a homogenous enhancement in the arterial phase and almost the same enhancement as the surrounding liver parenchyma in the delayed phase.The tumor was found to contain fat on magnetic resonance imaging.A benign fat containing liver tumor was suggested.However,radiological findings altered,which caused us to suspect that a welldifferentiated hepatocellular carcinoma(HCC)containing fat was becoming dedifferentiated.Partial hepatectomy was performed and the pathological findings showed the typical findings of LCA.This case was an extremely rare LCA,which had no background of risk for LCA and developed the sequential alteration of the radiological findings to suspect well-differentiated HCC. | Takayuki Kogure Yoshiyuki Ueno Satoshi Sekiguchi Kazuyuki Ishida Takehiko Igarashi Yuta Wakui Takao Iwasaki Tooru Shimosegawa | 2009 | World Journal of Gastroenterology2009，15，10： | 0 |
