- Brief Summary
The purpose of this study is to assess the effectiveness of a supplement with natural Mastiha on Inflammatory Bowel Diseases (IBD). U.S. Food and Drug Administration has classified Mastiha as GRAS. Previous research demonstrates Mastiha's safety, as well as anti-inflammatory, antimicrobial and antioxidant properties. In addition, the European Medicine Agency has recently recognized Mastiha as a natural medicine and classified it to the category of traditional herbal medicines in diarrhea problems, mild dyspeptic disorders, skin inflammation and healing (EMA/HMPC/46758/2015). Since IBD is a chronic disease characterized by inflammation and oxidative stress and based on previous small-scale studies, the present study aims at demonstrating the effectiveness of this supplement adjunct to the conservative treatment of IBD.
To this end, confirmed IBD patients, with distinguished Ulcerative Colitis (UC) and Crohn's Disease (CD) will be enrolled based on certain inclusion and exclusion criteria. The staff of the study will provide detailed information regarding the aims, the methods, anticipated benefits and potential hazards of the study and all patients will receive the Patient Information Leaflet (PIL). Ample time (48 hours) will be provided in order to decide whether they want to participate in the protocol. Each patient agreeing to participate will sign an Informed Consent document and the staff will explain to patients that they are under no obligation to enter the trial and that they can withdraw at any time during the trial, without having to give a reason. A copy of the signed Informed Consent will be given to the participant.
100 IBD patients will be allocated to either Mastiha or placebo group. The Mastiha group will receive natural Mastiha supplement at a dose of 2.8 g daily while placebo group will receive respectively placebo. The intervention will last 3 months for patients in relapse and 6 months for patients in remission. They will receive all the supplements they will consume during the intervention at the start of the trial. Both groups will continue their medical treatment, which must be unaltered throughout the trial. Additionally, all patients will receive standard nutritional advice by dieticians and will be encouraged to report any adverse effects they may experience during the intervention. The trial will be blinded in all implicated persons; neither the staff of the trial nor the patients will be aware of which kind intervention they receive.
Patients are assessed after randomisation according to the following tools:
* Medical history
* Dietary history
* Harvey \& Bradshaw Activity Index Assessment
* Mayo Activity Index assessment
* Anthropometric data measurement: body weight (kg), height (cm), Body Mass Index (kg/m2)
* Inflammatory Bowel Disease Questionnaire
* DNA isolation from whole blood.
* Biochemical measurements: Complete blood count, albumin, lipid profile, glucose, electrolytes, liver enzymes, amylase, fibrinogen.
* Evaluation of inflammation in serum samples. Circulating serum levels of IL-6, IL-8, IL-17A, IL-17F, IL-18, IL-21, IL-22, TL1A, TGF-β, ICAM-1, MADCAM-1 and E-selectin are measured), in all active CD and UC patients. Inflammatory markers are also estimated in stool samples: calprotectin, lactoferrin and lysozyme,
* Oxidative stress assessment in serum/plasma samples. Oxidised LDL, serum oxidisability and F2-isoprostanes are quantified.
* Detection of metabolites and complete metabolomic profile in plasma samples.
* Stool samples collection for the assessment of gut microbiota in active patients.
* Genetic and epigenetic profile
Subsequent assessments: There is a biweekly telephone contact with the patients to monitor compliance and side effects. At the end of the intervention each subject undergoes the baseline assessment.

Group Intervention Description Mastiha Mastiha This arm of patients will receive natural Mastiha supplements at the dosage of 2.8g daily. Patients with active disease will be administered with supplements for 3 months, whereas patients in remission will be administered with supplements for 6 months. Placebo Placebo This arm of patients will receive placebo . Patients with active disease will be administered with placebo for 3 months, whereas patients in remission will be administered with placebo for 6 months.
- Primary Outcome Measures
Name Time Method Inflammatory Bowel Disease Questionnaire (IBDQ) Change in IBDQ will be assessed at 3 months from baseline in active IBD patients and at 6 months in inactive IBD patients. Data will be presented through study completion, an average of 1 year.
- Secondary Outcome Measures
Name Time Method Objective symptoms questionnaire (rectal bleeding and stool frequency, visible blood in faeces and urgency). Change in objective symptoms will be assessed at 3 months from baseline in active IBD patients and at 6 months in inactive IBD patients. Data will be presented through study completion, an average of 1 year. C-reactive protein (CRP) Change in CRP will be assessed at 3 months from baseline in active IBD patients and at 6 months in inactive IBD patients. Data will be presented through study completion, an average of 1 year. Subjective symptoms questionnaire (physician rating of disease activity) Change in subjective symptoms will be assessed at 3 months from baseline in active IBD patients and at 6 months in inactive IBD patients. Data will be presented through study completion, an average of 1 year. Lab inflammatory biomarkers through sandwich Elisa assays. Change in lab inflammatory biomarkers will be assessed at 3 months from baseline in active IBD patients and at 6 months in inactive IBD patients. Data will be presented through study completion, an average of 1 year.
