Osteopathic Approach in Inflammatory Bowel Diseases

Study Overview
=================
Brief Summary
-----------------
Crohn's disease (CD) and ulcerative colitis are bowel disease (IBS) with an autoimmune component believed to affect approximately 1 in 140 Canadians. Despite this high prevalence, more than 30% patients with IBD have to live with recurrent gastrointestinal symptoms that is poorly relieved by allopathic medicine. Numerous studies have shown that the quality of life of individuals with IBS is lower than that of the general population. Since visceral manipulations have been shown to be effective in reducing the main discomforts associated with IBS during clinical interventions, it seems likely that it may provide similar relief to patients with IBD. To our best knowledge, no study has evaluated the impact of osteopathic manual therapy on neuro-immuno-vascular modulation of intestine to reduce IBS symptoms. The aim of this study is to assess the relevance of an osteopathic approach addressing the brain-intestine axis in order to improve symptomatology in subject suffering from IBD by modulating inflammation and vagal tone.

Detailed Description
-----------------
For this study, 10 to 12 participant (18 to 65 years) with Inflammatory Bowel Disease (in remission state) will be recruited to receiving visceral osteopathic therapy. Participant will received four standardized osteopathic session of 45 minutes (1 session every 7 days: week 0, 1, 2 and 3) and a follow up visit at week 4. The osteopathic protocol will specifically address the gut-to-brain neuro-immuno-vascular axis. Global quality of life and severity of IBS-like symptoms will be a assess at week 0, 2 and 4 using three standardized questionnaires. Gut permeability and intestinal inflammation will be assessed at week 0 and 4 by measuring Zonulin (pre-Haptoglobin 2), Histamine and Diamine Oxidase (DO) levels respectively. Vagal tone at the beginning and at the end of each osteopathic session will be evaluate using heart rate variability (HRV) measurements.

| Experimental: Osteopathic manipulation<br>Spinal Mobilisation / Cranial Osteopathy therapy / Circulatory Techniques / Visceral osteopathic therapy | Other: Manual Therapy: osteopathy<br>* Osteopathic protocol applied at week 0, 1, 2 and 3: Spinal mobilisation of L1, L2 and L3 vertebrae to stimulate the arterial supply of mesenteric attachments of the colon and small intestine. Visceral osteopathic therapy to address adhesions/ fixations in the presacral fascia, Toldt fascia, posterior peritoneum and caudal peritoneum. Circulatory techniques to stimulate the celiac plexus, the superior and inferior ganglia. Cranial osteopathy techniques to address the vagus parasympathetic nerves.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean Change from baseline in gut permeability marker | Zonulin (pre-Haptoglobin 2) on dried blood spot will be performed by FLUIDS iQ's analytical testing services (Intestinal iQ™ test kit). Zonulin (Pre-Haptoglobin 2) is a protein found in intestinal cells, with production and release mimicking the effect of certain bacterial toxins on the tight junctions of the small intestine. Zonulin binds to a specific receptor only on the luminal surface of the intestinal epithelia and triggers a cascade of biochemical processes that induces tight junction (TJ) disassembly and a subsequent permeability increase of the intestinal epithelia. The Zonulin range is from 1 to 20 ng/ml. Values between 1 and 6 ng/ml are considered as optimal Values between 6 and 10 ng/ml are considered as borderline Values from 10 to 20 ng/ml are considered as elevated | Week 0 (baseline); Week 4 | 
| Mean Change from baseline in intestinal inflammation markers | Histamine (ng/ml), Diamine Oxidase (DAO) on dried blood spot will be performed by FLUIDS iQ's analytical testing services (Intestinal iQ™ test kit). HISTAMINE Normal reference range: 0.2 to 2.4 ng/ml Below reference range: < 0.2 ng/ml Above reference range: > 2.4 ng/ml DAO Normal reference range: 12.5 to 3.75 ng/ml Below reference range, < 3.75 ng/ml Above reference range, > 12.5 ng/ml | Week 0 (baseline); Week 4 | 
| Mean Change from baseline in vagally mediated Heart Rate Variability (HRV) | The root mean square of successive differences between normal heartbeats (RMSSD) and Heart Rate Variability (HRV) will be recorded using Ultra-Short-Term measurement protocol (1-min resting). HRV and RMSSD will be measured at the start and at the end of each session. *Shaffer F, Ginsberg JP. An Overview of Heart Rate Variability Metrics and Norms.
