Evaluation of Infliximab Effects on Gastrointestinal Bleeding in Crohn's Disease Using Double-Balloon Endoscopy
Tumor necrosis factor α plays an important role in the pathogenesis of Crohn's disease (CD). The effects of infliximab on gastrointestinal bleeding in CD have not yet been fully evaluated. Herein we describe three CD cases who presented with gastrointestinal bleeding and received infliximab treatment. In case 1, double-balloon endoscopy showed a large ulcer with several irregularly shaped ulcers in the terminal ileum; 8 weeks after infliximab administration, complete healing of all lesions was observed. In case 2, double-balloon endoscopy showed linear ulcers and mucosal edema in the jejunum and ileum; 5 weeks after infliximab administration, all lesions were decreased in size and were healed. In case 3, double-balloon endoscopy revealed ulcerations and stenosis in the terminal ileum; 12 weeks after infliximab administration, ulcer healing and an increased diameter of the ileal stenosis were observed. These three cases have been receiving ongoing infliximab maintenance therapy and are currently symptom-free. Infliximab thus appears to be useful for treatment of gastrointestinal bleeding in CD patients
Peripheral Blood CD64 Levels Decrease in Crohn's Disease following Granulocyte and Monocyte Adsorptive Apheresis
Granulocyte and monocyte adsorptive apheresis (GMA) is reportedly useful as induction therapy for Crohn's disease (CD). However, the effects of GMA on CD64 have not been well characterized. We report here our assessment of CD64 expression on neutrophils before and after treatment with GMA in two patients with CD. The severity of CD was assessed with the CD activity index (CDAI). The duration of each GMA session was 60 min at a flow rate of 30 ml/min as per protocol. CD64 expression on neutrophils was measured by analyzing whole blood with a FACScan flow cytometer. In case 1, CD64 levels after each session of GMA tended to decrease compared to pretreatment levels, whereas in case 2, CD64 levels dropped significantly after treatment. The CDAI decreased after GMA in both cases 1 and 2. A significant correlation was noted between CDAI scores and CD64 levels in both cases. In conclusion, GMA reduced blood CD64 levels, which would be an important factor for the decrease of CDAI scores
A CASE OF TRAUMATIC RUPTURE OF A LIVER HEMANGIOMA TREATED BY HEPATECTOMY FOLLOWING TRANSCATHETER ARTERIAL EMBOLIZATION
Usefulness of Double-Balloon Endoscopy in the Postoperative Gastrointestinal Tract
Background. The small intestine has been considered to be a highly difficult organ to visualize in imaging examinations due to its anatomical location compared with the stomach and the colon. In recent years, many imaging modalities have become available, such as CT enterography, MR enterography, capsule endoscopy (CE), and double-balloon endoscopy (DBE). Patients and Methods. DBE was performed in the postoperative intestines of 91 patients (128 DBE examinations) at Iwate Medical University between 2004 and 2010. There were 61 male and 30 female patients, and their mean age was 69.7 years (range: 30–80 years). Results. A total of 124 DBE examinations were performed with endoscope insertion into the reconstructed intestines. The endoscope reached the blind end in 115 of 124 examinations, (92.7%). There were 17 patients with obscure gastrointestinal bleeding in whom 30 DBE examinations were performed. The bleeding site was identified in 12 patients (70.6%). Nine patients underwent endoscopic treatment. Hemostasis was achieved in all patients. Conclusion. DBE is very useful modality for the assessment and application of endotherapy to areas of the small bowel which have been altered by surgery
