Randomized controlled pilot study: effect of carrageenan emulsifier on inflammation and gastrointestinal symptoms in quiescent ulcerative colitis.

ABSTRACT:

Background

Animal models have provided some evidence of the pro-inflammatory effects of the commonly used emulsifier carrageenan. However, the effects of food-grade carrageenan among people with ulcerative colitis (UC) are largely unknown.

Methods

A randomized, placebo-controlled cross-over study comparing high molecular carrageenan and oat-based beta-glucan preparation (placebo) among patients (n = 7) with quiescent UC was performed. Primary endpoint was Simple Clinical Colitis Activity Index (SCCAI) at the end of the treatment (7th day). Secondary analyses included biochemical biomarkers of inflammation, intestinal permeability, detoxification of intestinal lipopolysaccharide (LPS), and gastrointestinal symptoms measured by visual analog scale.

Results

There were no statistically significant differences in SCCAI or any biochemical markers between carrageenan and placebo periods, nor were there any significant differences when comparing either period to baseline. Gastrointestinal symptoms were higher during the placebo period; the sum of all symptoms and borborygmi was statistically significantly higher at the end of the placebo period than at the end of the carrageenan period (20.8 ± 18.6 vs. 13.3 ± 16.4; P = 0.031, and 29.7 ± 28.6 vs. 17.9 ± 23.6; P = 0.016).

Conclusions

Our study suggests that at least short-term usage of food-grade carrageenan is safe among people with UC, but given the limitations of the current study, robust human studies are still urgently needed.

Project description:IntroductionDiscordance between gastrointestinal (GI) symptoms and endoscopic inflammation in patients with ulcerative colitis (UC) is known. However, the correlations between symptoms and endoscopic and histologic (endo-histologic) mucosal healing and remains unknown.MethodsWe performed a secondary analysis of prospectively collected clinical, endoscopic, and histologic data on 254 colonoscopies from 179 unique adults at a tertiary referral center from 2014 to 2021. Spearman's rank was used to assess the correlation between patient reported outcomes and objective assessments of disease activity, as measured by validated instruments: Two-item patient-reported outcome measure (PRO-2) for stool frequency and rectal bleeding, the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) for endoscopic inflammation, and the Geboes score for histologic inflammation. The predictive value of objective assessments of inflammation and clinical symptoms was described using sensitivity, specificity, and positive/negative predictive value.ResultsOne-quarter (28%, 72/254) of cases were in endo-histologic remission; of these, 25% (18/72) report GI symptoms (22% diarrhea; 6% rectal bleeding). Endo-histologically active disease had higher sensitivity (95% rectal bleeding; 87% diarrhea) and negative predictive value (94% rectal bleeding, 78% diarrhea) for clinically active disease compared to active disease on endoscopic (77%) or histologic assessment only (80%). The specificity of endo/histologic inflammation for GI symptoms was < 65%. PRO-2 was positively correlated with endoscopic disease activity (Spearman's rank 0.57, 95% CI 0.54-0.60, p < 0.0001) and histologic disease activity (Spearman's rank 0.49, 0.45-0.53, p < 0.0001).ConclusionOne-quarter of patients with ulcerative colitis in endo-histologic (deep) remission have gastrointestinal symptoms, more commonly with diarrhea than rectal bleeding. Endo-histologic inflammation has high sensitivity (≥ 87%) for diarrhea/rectal bleeding.

Project description:BackgroundUlcerative colitis (UC) is a chronic inflammatory disorder of the colon. Several preclinical studies investigated the beneficial effects of atorvastatin in colitis. Activation of sphingosine 1 phosphate (S1P)/ tumor necrosis factor-alpha (TNF-α)/ interleukin-6 (IL-6) pathways has been confirmed in the pathogenesis of UC and preclinical studies proved the efficacy of atorvastatin on these pathways.AimTo investigate the role of atorvastatin on S1P/TNF-α/IL-6 pathway in UC.MethodsPatients with mild to moderate UC were allocated into two groups in this pilot study. For 6 months, Group 1 (placebo group) received both a placebo and 1 g of mesalamine three times daily (t.i.d.). Group 2, (the atorvastatin group) received atorvastatin 80 mg once daily and 1 g of mesalamine t.i.d. A gastroenterologist evaluated the patients' colitis severity by partial Mayo score index (PMS). Serum IL-6, S1P, TNF-α, nitric oxide (NO), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and fecal calprotectin were measured before and after treatment. Short Form 36 questionnaire (SF-36) was also assessed. A clinical response was defined as a decline in the rectal bleeding sub score of at least one point, and a decrease in PMS of at least two points. Clinical remission was defined as a PMS of less than 2 and the absence of any single sub score greater than 1.Primary outcomeDecreased PMS and improved quality of life.Secondary outcomeChange in the level of measured biomarkers.ResultsCompared to the placebo group (n = 24), the atorvastatin group (n = 23) exhibited a significant decrease in the level of IL-6 (p = 0.001), S1P (p = 0.0001), TNF-α (p = 0.003), NO (p = 0.0001), CRP (p = 0.015), ESR (p = 0.012), PMS (p = 0.013), and fecal calprotectin (p = 0.0003), and improved SF-36 (p = 0.006). In placebo group, the response rate was 83.33% (n = 20/24) for PMS, and the remission rate was 45.83% (n = 11/24). In the atorvastatin group, the response rate was 91.3% (n = 21/23), and the remission rate was 60.8% (n = 14/23) for PMS.ConclusionAtorvastatin could be an adjunctive therapy for patients with UC.Clinical trial registrationhttps://www.clinicaltrials.gov/, Identifier NCT05561062.

Project description:IntroductionUlcerative colitis (UC) and irritable bowel syndrome (IBS) are distressing chronic diseases associated with abdominal pain and altered bowel habits of unknown aetiology. Results from previous studies indicate that, across both diseases, increased levels of illness-related anxiety and dysfunctional symptom expectations contribute to symptom persistence. Thus, comparing both disorders with regard to common and disease-specific factors in the persistence and modification of gastrointestinal symptoms seems justified. Our primary hypothesis is that persistent gastrointestinal symptoms in UC and IBS can be improved by modifying dysfunctional symptom expectations and illness-related anxiety using expectation management strategies.Methods and analysisTo assess the extent to which persistent somatic symptoms are modifiable in adult patients with UC and IBS, we will conduct an observer-blinded, three-arm randomised controlled trial. A total of 117 patients with UC and 117 patients with IBS will be randomised into three groups of equal size: targeted expectation management aiming to reduce illness-related anxiety and dysfunctional symptom expectations in addition to standard care (SC, intervention 1), non-specific supportive treatment in addition to SC (intervention 2) or SC only (control). Both active intervention groups will comprise three individual online consultation sessions and a booster session after 3 months. The primary outcome is baseline to postinterventional change in gastrointestinal symptom severity.Ethics and disseminationThe study was approved by the Ethics Committee of the Hamburg Medical Association (2020-10198-BO-ff). The study will shed light onto the efficacy and mechanisms of action of a targeted expectation management intervention for persistent gastrointestinal symptoms in patients with UC and IBS. Furthermore, the detailed analysis of the complex biopsychosocial mechanisms will allow the further advancement of aetiological models and according evidence-based intervention strategies.Trial registration numberISRCTN30800023.
