Despite a considerable placebo effect, the benefits of tandospirone were shown in terms of improvement in abdominal symptom scores.

Background/Aims: A new classification of achalasia using high-resolution manometry (HRM) has recently been suggested. Pneumatic dilatation (PD) is a common treatment for primary achalasia. The usefulness of the new classification and HRM for the treatment and follow-up of patients after PD is unknown. The aim of this study was to evaluate the PD effectiveness and the predictive factors of success in Japanese patients with achalasia using HRM and the new classification of achalasia. Methods: Twenty-five patients were diagnosed with primary achalasia using HRM and treated by PD in our hospital. We evaluated symptom scores and esophageal manometry 6 and 12 months after the first PD. Results: After the first PD treatment, remission occurred in 24 out of 25 (96.0%) patients at 6 months and in 19 out of 25 (76.0%) patients at 12 months. With the new classification of achalasia, the success rates were 83.3, 80.0 and 50% for types I, II and III, respectively, 12 months after PD. The median age of the successful group was significantly greater than that of the failure group (47.1 vs. 37.0 years, p <0.05). The median residual lower esophageal sphincter (LES) pressure 6 months after PD in the successful group was significantly lower than that of the failure group (9.0 vs. 15.5 mm Hg, p <0.05). Conclusion: Good predictors of PD success were old age (>40 years) and residual LES pressures less than 15 mm Hg 6 months after PD.

Background:Helicobacter pylori eradication rates have decreased worldwide. Gastric acid inhibition during treatment is important to eradicate these bacteria successfully. A new potassium-competitive acid blocker, vonoprazan (VPZ), has been shown to achieve high eradication rates in a previous randomized controlled trial. Objective: To determine the efficacy of VPZ for H. pylori eradication. Methods: A total of 874 patients were enrolled; 431 received esomeprazole (EPZ) and 443 received VPZ. First-line regimens contained clarithromycin (CAM) 200 mg b.i.d., amoxicillin 750 mg b.i.d., and either EPZ 20 mg b.i.d. or VPZ 20 mg b.i.d. for 7 days. Metronidazole 250 mg b.i.d. replaced CAM in the second-line regimens. The eradication of H. pylori was assessed by ¹³C-urea breath tests 4-8 weeks after each therapy. Results: The overall first-line eradication rate was 79.9% (341/427) with EPZ vs. 86.3% (377/439) with VPZ (p = 0.019). The second-line eradication rate was 83.3% (45/51) with EPZ vs. 91.1% (41/45) with VPZ (p = 0.900). Conclusion: VPZ was significantly more effective than EPZ for first-line treatment. However, for second-line treatment, there was no significant difference between EPZ and VPZ.

Background and aim: Cytomegalovirus (CMV) exacerbates ulcerative colitis (UC) refractory to immunosuppressive therapies. The conditions under which CMV reactivation occurs in patients with UC, however, is unclear. In addition, the diagnostic and treatment strategies for UC positive for CMV have not been established. Granulocyte and monocyte adsorptive apheresis (GMAA) is natural biological therapy for UC in which the granulocytes/macrophages producing inflammatory cytokines are removed. We investigated the rate of colonic CMV reactivation and the efficacy of GMAA in active UC patients positive for CMV without concomitant corticosteroid (CS) therapy. Methods: Fifty-one active UC patients without concomitant CS therapy were enrolled. Colonic CMV reactivation was examined by real-time polymerase chain reaction (PCR) using biopsy specimen and/or histological examination. All patients were treated with intensive GMAA (twice per week). Rates of clinical remission and mucosal healing were compared between UC patients positive and negative for CMV. Results: Of 51 patients, 15 (29.4%) were diagnosed as CMV positive. The clinical remission rates following intensive GMAA did not differ between UC patients positive and negative for CMV (73.3% vs 69.4%, p = 0.781). Proportion of patients achieving mucosal healing was also similar A v a i l a b l e o n l i n e a t w w w . s c i e n c e d i r e c t . c o m ScienceDirectJournal of Crohn's and Colitis (2013) 7, 803-811 Downloaded from https://academic.oup.com/ecco-jcc/article-abstract/7/10/803/378961 by guest on 07 June 2019 between these two groups. CMV-DNA became negative in all UC patients positive for CMV who achieved clinical remission 1 week after completion of intensive GMAA. Conclusions: Intestinal inflammation might trigger CMV reactivation in a subpopulation of active UC patients without CS treatment. GMAA could be a promising option for active UC positive for CMV.

BackgroundEarly induction with biologics can reduce complications in patients with Crohn’s disease (CD) and improve their quality of life. The safety of biologics, however, is uncertain. Granulocyte and monocyte adsorptive apheresis (GMAA) is a natural biologic therapy that selectively removes granulocytes and monocytes/macrophages and has few severe adverse effects. The effects of GMAA on patients with early-diagnosed CD are unclear. We investigated the effects of GMAA combined with thiopurines on patients with early-diagnosed CD.MethodsTwenty-two corticosteroid- and biologic-naïve patients with active early-diagnosed CD were treated with intensive GMAA (twice per week) combined with thiopurines administration. Active early-diagnosed CD was defined as follows: (i) within 2years after diagnosis of CD, (ii) with no history of both surgical treatment and endoscopic dilation therapy, and (iii) Crohn’s Disease Activity Index (CDAI) was higher than 200. We investigated the ratios of clinical remission defined as CDAI was less than or equal to 150 at 2, 4, 6 and 52weeks and mucosal healing defined as a Simplified Endoscopic Activity Score for Crohn’s Disease (SES-CD) as 0 at 6 and 52weeks. Adverse events were recorded at each visit.ResultsThe ratios of clinical remission at 2, 4, and 6 weeks were 6 of 22 (27.2%), 12 of 22 (54.5%), and 17 of 22 (77.2%), respectively. At 52 weeks, 18 of 21 patients (81.8%) were in clinical remission. The ratios of mucosal healing at 6 and 52 weeks were 5 of 22 (22.7%) and 11 of 22 (50%), respectively. The difference in the mucosal healing ratio was significant between 6 and 52 weeks (p = 0.044). No serious adverse effects were observed during this study.ConclusionsCombination therapy with intensive GMAA and thiopurines administration rapidly induced high remission in patients with active early-diagnosed CD without serious adverse effect. Mucosal healing was observed in 50.0% of enrolled patients. This combination therapy might be a rational option for patients with early-diagnosed CD.

Background: Cytomegalovirus (CMV) infection exacerbates ulcerative colitis (UC) refractory to immunosuppressive therapies (IMT). However, the underlying UC remained active in some UC patients, despite the fact that CMV-DNA in colonic mucosa became negative after antiviral therapy. Therefore, new therapeutic strategies for UC patients concomitant with CMV infection in mucosa are required. Aims: The aim of this study was to evaluate the effect and safety of granulocyte-monocyte adsorption apheresis (GMA) in UC patients positive for CMV infection after antiviral therapy. Methods: From October 2003 to December 2008, 64 patients with UC refractory to IMT, including steroids and immunomodulators, were enrolled in this retrospective, observational, multicenter study, which was reviewed and approved by the Institutional Review Board of Kyoto University. CMV infection was investigated by 3 methods (histologic examination, CMV antigenemia, and polymerase chain reaction). We investigated the clinical outcomes of GMA and IMT after 2 weeks of treatment with ganciclovir. Results: Thirty-one (48.4%) of 64 patients with UC refractory to IMT were positive for CMV. Of the 31 patients, 4 (12.9%) underwent colectomy. Twenty-seven patients (87.1%) underwent antiviral therapy. Of those 27 patients, 7 achieved remission following antiviral therapy alone. Of the remaining 20 patients who did not achieve remission despite the disappearance of CMV-DNA, 11 and 9 patients were treated with additional GMA (GMA group) and IMT (IMT group), respectively. Of 11 patients (GMA group), 9 achieved remission and 2 underwent colectomy. Out of the remaining 9 patients (IMT group), 4 achieved remission and 5 underwent colectomy. CMV-DNA was not detected in 11 patients after GMA, but it was detected again in all 5 patients of the IMT group who underwent colectomy. The total colectomy rate in UC patients positive for CMV was 35.5% (11/31). In addition, colectomy-free survival in the CMV relapse (+) group was estimated to be 12.9% at 65 months, while that in the CMV relapse (–) group was estimated to be 100% at 60 months. Conclusion: The colectomy ratio tends to be high in refractory UC patients with recurrent CMV reactivation or infection. Therefore, GMA might be a safe and effective treatment for UC patients positive for CMV because it does not induce CMV reactivation.
