1: Analysis of clinical course and long-term prognosis of surgical and nonsurgical patients with intestinal Behçet's disease.
著者: M Naganuma, Y Iwao, N Inoue, T Hisamatsu, H Imaeda, H Ishii, T Kanai, M Watanabe, T Hibi
雑誌名: Am J Gastroenterol. 2000 Oct;95(10):2848-51. doi: 10.1111/j.1572-0241.2000.03198.x.
Abstract/Text: OBJECTIVE: Much remains unknown about the pathogenesis of intestinal Behçet's disease. The majority of these patients are treated with surgical intervention, although it has been recently reported that a number of medical treatments are sometimes effective. Only few studies, however, have ever been undertaken to analyze the long-term prognosis of this disease. In this study, we analyzed the clinical course and the recurrences after initial therapy in patients with intestinal Behçet's disease.
METHODS: We investigated 20 patients (surgical group, n = 8; nonsurgical group, n = 12) for whom the clinical courses were known for > or = 2 yr (2-23 yr).
RESULTS: The surgical group tended to have higher rates of complications such as ocular and ileal lesions than the nonsurgical group. In the surgical group, 75% of the patients recurred (and were readmitted) within 2 yr, and 37.5% of the patients required reoperation for intestinal obstruction because of ulcer at the anastomosis. The percentage of peripheral CD8+ DR+ lymphocytes in the recurrent group (10.4% +/- 2.5%) was significantly higher than that in the nonrecurrent group (4.3% +/- 1.2%, p < 0.05).
CONCLUSIONS: Our results indicate that more extensive disease involving the ileum and ocular lesions are markers of severity and progression to surgical crisis, and that patients requiring surgery suffer more frequent recurrences. Furthermore, an increased percentage of peripheral CD8+ DR+ lymphocytes may be a risk factor for disease recurrence.

1: Efficacy of infliximab for induction and maintenance of remission in intestinal Behçet's disease.
著者: Makoto Naganuma, Atsushi Sakuraba, Tadakazu Hisamatsu, Hiroki Ochiai, Hirotoshi Hasegawa, Haruhiko Ogata, Yasushi Iwao, Toshifumi Hibi
雑誌名: Inflamm Bowel Dis. 2008 Sep;14(9):1259-64. doi: 10.1002/ibd.20457.
Abstract/Text: BACKGROUND: Intestinal Behçet disease (BD) is characterized by intestinal inflammation with round and oval ulcers associated with gastrointestinal symptoms. Although several cases have been reported that infliximab is effective for induction of remission, the efficacy of infliximab for maintaining remission is unknown.
METHODS: Six cases with fulminant intestinal BD were treated with infliximab. All patients were steroid-dependent and refractory to immunosuppressants; 3 patients were treated with 6-mercaptopurine, 1 patient with azathioprine, 1 patient with cyclosporine A, and 1 patient with methotrexate.
RESULTS: Four patients achieved remission by infliximab and all of these patients maintained remission with scheduled treatments of infliximab, with the longest duration of remission being about 3 years. Another 2 patients with ileal ulceration required surgery; however, 1 patient has maintained remission by scheduled treatment of infliximab for 2 years after surgery.
CONCLUSIONS: Infliximab appears to offer an option for fulminant intestinal BD to induce and maintain remission, although a randomized control trial is needed.

1: Clinical outcomes and prognostic factors for thiopurine maintenance therapy in patients with intestinal Behcet's disease.

雑誌名: Inflamm Bowel Dis. 2012 Apr;18(4):750-7. doi: 10.1002/ibd.21757. Epub 2011 May 25.
Abstract/Text: BACKGROUND: To date, there have been no studies focusing on the efficacy of thiopurine therapy in intestinal Behcet's disease (BD). We conducted this study to investigate clinical outcomes and predictors of clinical relapse in intestinal BD patients receiving thiopurine maintenance therapy.
METHODS: We reviewed the medical records of all patients with intestinal BD who received thiopurine therapy in a single tertiary academic medical center between March 1986 and October 2010. The cumulative probabilities of clinical relapse after remission were calculated using the Kaplan-Meier method. Predictors of clinical relapse were identified by univariate analysis using the log-rank test and by multivariate analysis using Cox proportional hazards regression models.
RESULTS: Of a total of 272 patients with intestinal BD, 67 (24.6%) received their first course of thiopurine therapy at our center. Thirty-nine (58.2%) of the 67 patients constantly received thiopurines for maintaining medically or surgically induced remission. The cumulative relapse rates at 1 year, 2 years, 3 years, and 5 years after remission were 5.8%, 28.7%, 43.7%, and 51.7%, respectively. On multivariate analysis, a younger age (<25 years) at diagnosis and a lower hemoglobin level (<11 g/dL) were independent predictive factors for relapse in intestinal BD patients receiving thiopurine maintenance therapy.
CONCLUSIONS: Thiopurine therapy showed a relatively good effect for maintenance of remission in intestinal BD patients. However, a younger age at diagnosis and a lower hemoglobin level were associated with a poor response to thiopurines, necessitating early adoption of effective alternative therapeutic options in these risk groups.
