AIM: To clarify the impact of cytomegalovirus (CMV) activation and antiviral therapy based on CMV antigen status on the long-term clinical course of ulcerative colitis (UC) patients. METHODS: UC patients with flare-up were divided into CMV-positive and -negative groups according to the CMV antigenemia assay. The main treatment strategy provided for the patients in the CMV-positive group comprised a dose reduction of corticosteroids and administration of ganciclovir. RESULTS: The median number of days to initial remission was significantly greater for the patients in the CMV-positive group (21 d vs 16 d, P = 0.009). However, the relapse rate after remission and colectomy rate during more than 30 mo of observation did not differ between the two groups. Multivariate analysis revealed that administration of ganciclovir was the only independent factor for avoiding colectomy in patients of the CMV-positive group. CONCLUSION: CMV antigen status did not significantly affect the long-term prognosis in UC patients under treatment with appropriate antiviral therapy.

OBJECTIVE: Although the serum C-reactive protein (CRP) level may, to some extent, predict the disease activity in patients with Crohn's disease (CD), it is not always elevated during periods of disease activity. This study aimed to identify factors predicting the presence of active intestinal lesions in CD patients without an elevated CRP level. METHODS: CD patients in whom the presence or absence of active intestinal lesions was evaluated using endoscopic and/or radiologic modalities were divided into two groups based on a negative (<3 mg/L) or positive (≥3 mg/L) CRP level. The correlations between the presence of active intestinal lesions and various clinical variables, including the Crohn's Disease Activity Index (CDAI), leukocyte and platelet counts and hemoglobin, serum albumin and CRP levels, were determined in the CRP-negative patients. RESULTS: Of the 128 patients examined, 70 had a negative CRP status, approximately half of whom had active intestinal lesions. The multivariate analysis revealed a CDAI of >100 and platelet count of >33×10(4)/μL to be significant predictive factors for the presence of active lesions in the CRP-negative patients [CDAI >100, odds ratio (OR) =5.55; 95% confidence interval (CI), 1.80-18.74, platelet count >33×10(4)/μL, OR =5.94; 95% CI, 1.34-28.87]. The sensitivity of fulfillment of either criterion for the presence of active intestinal lesions was 83%, while the specificity of fulfillment of both criteria was 94%. CONCLUSION: A relatively low CDAI and platelet count were identified as predictive markers of the presence of active intestinal lesions in CRP-negative CD patients. These results suggest that symptoms and laboratory data should be evaluated very carefully in such patients.

BACKGROUND: Although hyoscine butyl bromide (HB) and glucagon (GL) are often used as antispasmodic drugs during esophagogastroduodenoscopy (EGD), these agents may cause adverse effects. Recently, it was reported that peppermint oil solution (PO) was very effective and had few side effects. AIM: We clarified the efficacy and usefulness of PO as an antispasmodic during upper endoscopy, especially for elderly patients. METHODS: This study was a non-randomized prospective study. The antispasmodic score (1-5, where 5 represents no spasm) was defined according to the degree of spasms of the antrum and difficulty of biopsy. We compared the antispasmodic scores between non-elderly patients (younger than 70) and elderly patients (70 years old or older) according to the antispasmodic agent. RESULTS: A total of 8,269 (Group PO: HB: GL: NO (no antispasmodic) = 1,893: 6,063: 157: 156) EGD procedures were performed. There was no significant difference in the antispasmodic score between Group PO (mean score ± standard deviation: 4.025 ± 0.925) and Group HB (4.063 ± 0.887). Among the non-elderly patients, those in Group PO (n = 599, 3.923 ± 0.935) had a worse antispasmodic score than those in Group HB (n = 4,583, 4.062 ± 0.876, P < 0.001). However, among the elderly patients, those in Group PO (n = 1,294, 4.073 ± 0.917) had similar scores to those in Group HB (n = 1,480, 4.064 ± 0.921, P = 0.83), and significantly better scores than those in Group GL (n = 69, 3.797 ± 0.933, P < 0.05). CONCLUSION: Peppermint oil was useful as an antispasmodic during EGD, especially for elderly patients.
