Intravenous steroids are the first-line therapy for ulcerative colitis (UC) patients who are hospitalised during a severe UC flare-up. In the 40% of patients who don’t respond to steroids, the drugs ciclosporin and infliximab have been found to be efficient in preventing surgery to remove part or all of the colon, but there is a lack of data on the long-term outcomes of using these medications in UC patients. The aim of this study was to assess long-term outcome of patients included in a randomised trial comparing ciclosporin and infliximab. Between 2007 and 2010, 115 patients with UC that did not respond to steroids were randomised to receive ciclosporin or infliximab in association with azathioprine. Patients were followed to January 2015 or death. After a median follow-up of 5.4 years, colectomy-free survival rates at 1 and 5 years were, respectively, 70.9% and 61.5% in patients who received ciclosporin and 69.1% and 65.1% in those who received infliximab. Long-term colectomy-free survival was independent from initial treatment. However, a higher proportion of patients initially treated with ciclosporin needed a new treatment compared with those who received infliximab first. The researchers concluded that these results further confirm a similar efficacy and good safety profiles of both drugs.
Abstract
OBJECTIVE Ciclosporin and infliximab have demonstrated short-term similar efficacy as second-line therapies in patients with acute severe UC (ASUC) refractory to intravenous steroids. The aim of this study was to assess long-term outcome of patients included in a randomised trial comparing ciclosporin and infliximab. DESIGN Between 2007 and 2010, 115 patients with steroid-refractory ASUC were randomised in 29 European centres to receive ciclosporin or infliximab in association with azathioprine. Patients were followed until death or last news up to January 2015. Colectomy-free survival rates at 1 and 5 years and changes in therapy were estimated through Kaplan-Meier method and compared between initial treatment groups through log-rank test. RESULTS After a median follow-up of 5.4 years, colectomy-free survival rates (95% CI) at 1 and 5 years were, respectively, 70.9% (59.2% to 82.6%) and 61.5% (48.7% to 74.2%) in patients who received ciclosporin and 69.1% (56.9% to 81.3%) and 65.1% (52.4% to 77.8%) in those who received infliximab (p=0.97). Cumulative incidence of first infliximab use at 1 and 5 years in patients initially treated with ciclosporin was, respectively, 45.7% (32.6% to 57.9%) and 57.1% (43.0% to 69.0%). Only four patients from the infliximab group were subsequently switched to ciclosporin. Three patients died during the follow-up, none directly related to UC or its treatment. CONCLUSIONS In this cohort of patients with steroid-refractory ASUC initially treated by ciclosporin or infliximab, long-term colectomy-free survival was independent from initial treatment. These long-term results further confirm a similar efficacy and good safety profiles of both drugs and do not favour one drug over the other.

Plain language summary
AndoSanTM is a medicinal mushroom supplement based on Agaricus Blazei Murrill (ABM), but also contains Hericium erinaceus (lion’s mane, 14.7%) and Grifola frondosa (Maitake, 2.9), and contains immune modulatory beta-glucans as well as other bioactive compounds. This single-centre randomised two-armed patient-blinded study was designed to determine whether daily oral intake of AndoSanTM could improve clinical symptoms, fatigue and quality of life in patients with mild to moderate ulcerative colitis (UC). Patients received either AndoSanTM 60ml per day or placebo for 21 days and were evaluated before start of treatment and at day 14 and 21. Outcome measures were a modified Clinical Activity Index (CAI)), the self-reported health-related quality of life (HRQoL), a fatigue questionnaire, blood parameters and faecal calprotectin (a marker for intestinal inflammation). 24 patients in the AndoSanTM arm and 26 in the placebo arm completed the trial and were included in study analysis. Compared with baseline only the patients in the AndoSan™ group reported significant reductions of symptoms, fatigue and quality of life which were significantly better than in the placebo group. There were no significant changes in blood parameters in either group. There was no change in calprotectin in the AndoSanTM group but a significant worsening in the placebo group. No adverse effects were reported. A limitation of the study is that it was only blinded to the patients but not to the investigators. The authors conclude that AndoSan™ may be beneficial as a supplement to conventional medication in patients with mild to moderate UC.
Abstract
BACKGROUND Ingestion of AndoSan™, based on the mushroom Agaricus blazei Murill, has previously been shown to exhibit anti-inflammatory effects because of reduction of pro-inflammatory cytokines in healthy individuals and patients with ulcerative colitis. In this randomized single-blinded placebo controlled study we examined whether intake of AndoSan™ also resulted in clinical effects. METHODS AND FINDINGS 50 patients with symptomatic ulcerative colitis were block-randomized and blinded for oral daily intake of AndoSan™ or placebo for the 21 days' experimental period. The patients reported scores for symptoms, fatigue and health related quality of life (HRQoL) at days 0, 14 and 21. Fecal calprotectin and general blood parameters were also analyzed. In the AndoSan™ group (n = 24) symptoms improved from baseline (day 0) to days 14 and 21, with respective mean scores (95% CI) of 5.88 (4.92-6.83), 4.71 (3.90-5.52) (p = 0.002) and 4.50 (3.70-5.30) (p = 0.001). Corresponding improved mean scores (±SD) for total fatigue were 16.6 (5.59), 14.1 (4.50) (p = 0.001) and 15.1 (4.09) (p = 0.023). These scores in the placebo group (n = 26) were not improved. When comparing the two study groups using mixed model statistics, we found significant better scores for the AndoSan™-patients. HRQoL for dimensions bodily pain, vitality, social functioning and mental health improved in the AndoSan™ group. There were no alterations in general blood samples and fecal calprotectin. CONCLUSIONS Beneficiary effects on symptoms, fatigue and HRQoL from AndoSan™ consumption were demonstrated in this per-protocol study, supporting its use as a supplement to conventional medication for patients with mild to moderate symptoms from ulcerative colitis. The patients did not report any harms or unintended effects of AndoSan™ in this study. TRIAL REGISTRATION ClinicalTrials.gov NCT01496053.
