BACKGROUND/AIMS: Inflammatory bowel disease (IBD) is a chronic disease of the gastrointestinal tract, whose etiologies are still unknown. This study was performed to evaluate the humoral immune response in terms of B cell functions in selected IBD patients. METHODS: Eighteen pediatric patients with IBD, including 12 cases of ulcerative colitis (UC) and six with Crohn disease (CD), were enrolled in this study. The pneumococcal vaccine was injected in all patients, and the IgG antibody level to the polysaccharide antigen was measured before and 4 weeks after injection. The B cell switch-recombination process was evaluated. RESULTS: Five patients with IBD (three CD and two UC) had defects in B cell switching, which was significantly higher than in controls (p=0.05). Ten patients had a specific antibody deficiency and exhibited a higher frequency of bacterial infection than the healthy group. The mean increased level of IgG after vaccination was lower in IBD patients (82.9+/-32.5 microg/mL vs 219.8+/-59.0 microg/mL; p=0.001). Among the patients who had an insufficient response, no significant difference in the number of switched memory B-cell was observed. CONCLUSIONS: A defect in B lymphocyte switching was observed in pediatric IBD patients, and especially in those patients with CD. Owing to an increased risk of bacterial infections in those patients with antibody production defects, pneumococcal vaccination could be recommended. However, not all patients can benefit from the vaccination, and several may require other prophylactic methods.

OBJECTIVETo reveal the efficacy on early postoperative inflammatory small bowel obstruction (EPISBO) treated with electroacupuncture and acupuncture separately and make the comparison of the efficacy difference.

METHODSThrough retrospective analysis, 459 cases of EPISBO were divided into an electroacupuncture group (355 cases) and an acupuncture group (104 cases). Based on routine treatment, Zusanli (ST 36), Shangjuxu (ST 37), Taichong (LR 3), Gongsun (SP 4) and Xuanzhong (GB 39) were selected in either group, but stimulated with electroacupuncture and acupuncture separately, once per day, for 30 min each time.

RESULTSAll of 459 cases were cured. The average days of curative achievement in electroacupuncture group were less apparently than those in acupuncture group (13.5 +/- 7.5 vs. 20.8 +/- 6.5, P < 0.05). The days of curative achievement in either group were less significantly than those treated with parenteral nutrition and medication recorded in literatures (32.0 +/- 7.0, both P < 0.05).

CONCLUSIONEither electroacupuncture or acupuncture achieves a significant efficacy on EPISBO, but the efficacy of electroacupuncture is better than that of acupuncture.
