Abstract Background Granulocyte and monocyte adsorptive apheresis (GMA) is widely used as a remission induction therapy for active ulcerative colitis (UC) patients. However, there are no available biomarkers for predicting the clinical outcome of GMA. We investigated the utility of Fecal calprotectin (FC) as a biomarker for predicting the clinical outcome during GMA therapy in active UC patients. Methods In this multicenter prospective observation study, all patients received 10 sessions of GMA, twice a week, for 5 consecutive weeks. FC was measured at entry, one week, two weeks, and at the end of GMA. Colonoscopy was performed at entry and after GMA. The clinical activity was assessed based on the partial Mayo score when FC was measured. Clinical remission (CR) was defined as a partial Mayo score of ≤ 2 and endoscopic remission (ER) was defined as Mayo endoscopic subscore of either 0 or 1. We analyzed the relationships between the clinical outcome (CR and ER) and the change in FC concentration. Result Twenty-six patients were included in this study. The overall CR and ER rates were 50.0% and 19.2%, respectively. After GMA, the median FC concentration in patients with ER was significantly lower than that in patients without ER (469 mg/kg vs. 3107 mg/kg, p = 0.03). When the cut-off value of FC concentration was set at 1150 mg/kg for assessing ER after GMA, the sensitivity and specificity were 0.8 and 0.81, respectively. The FC concentration had significantly decreased by one week. An ROC analysis demonstrated that the reduction rate of FC (ΔFC) at 1 week was the most accurate predictor of CR at the end of GMA (AUC = 0.852, P = 0.002). When the cut-off value of ΔFC was set at ≤ 40% at 1 week for predicting CR at the end of GMA, the sensitivity and specificity were 76.9% and 84.6%, respectively. Conclusion We evaluated the utility of FC as a biomarker for assessing ER after GMA and predicting CR in the early phase during GMA in patients with active UC. Our findings will benefit patients with active UC by allowing them to avoid unnecessary invasive procedures and will help establish new strategies for GMA.

Steroid Refractory

Background/Aims. Antitumor necrosis factor antibodies and calcineurin inhibitors have shown good therapeutic efficacy for steroid-refractory ulcerative colitis (UC). Although some studies have compared the efficacy of infliximab (IFX) and cyclosporin A, there are no published studies comparing IFX and tacrolimus (Tac). This study aimed to compare therapeutic efficacies between IFX- and Tac-based strategies for steroid-refractory UC.Methods. Between July 2009 and August 2013, 95 patients with steroid-refractory UC received either IFX(n=48)or Tac(n=47)in our hospital. In the IFX group, the patients continued to receive maintenance treatment with IFX. In the Tac group, patients discontinued Tac treatment up to 3 months and subsequently received thiopurine. We retrospectively compared the therapeutic outcomes between the groups.Results. There was no significant difference in the colectomy-free rate, clinical remission rate, and clinical response rate at 2 months between the groups. However, relapse-free survival was significantly higher in the IFX group than in the Tac group (p<0.001; log-rank test). The proportions of serious adverse events did not differ between the groups.Conclusion.The findings of our study showed that IFX and Tac have similar short-term therapeutic efficacy for steroid-refractory UC. Maintenance treatment with IFX, however, yields better long-term outcomes than Tac-thiopurine bridging treatment.

Histological Remission

Current conception of deep remission in patients with ulcerative colitis (UC) consists of clinical remission, endoscopic mucosal healing and normalization of laboratory markers. Histological remission should not be used as a primary end point for therapeutic efficacy, but instead should be considered as a marker of deep remission. The main goal of UC treatment should be focused on endoscopic healing of colon mucosa, decrease of inflammation activity, prolonged remission, absence of disease recurrence, and also histologic remission. Nevertheless, the term histologic remission has not yet been fully validated and no histologic indexes have been standardized. We need single unified definition for remission, based on multicentral studies analysis. One of important challenge is restoration of normal colon mucosal and results of multiple studies showed contradictory tests for assessing histologic remission, thus remaining an issue for further discussion.

Abstract Background Granulocyte and monocyte adsorptive apheresis (GMA) has been used for therapy of steroid-dependent/refractory ulcerative colitis (UC). The aim of this study was to investigate the effectiveness of GMA in UC patients not receiving steroids. Methods We conducted a single-arm, open-label, and multicenter prospective clinical trial. UC patients who had insufficient responses to 5-aminosalicylic acid received GMA twice a week for 5 weeks. Results The response rate of all patients was 58.2% (39/67). Of the 39 patients who achieved a response, 74.4% achieved endoscopically confirmed mucosal healing. Conclusions GMA shows effectiveness in inducing remission in UC patients not receiving steroid.
