The Dilemma of Persistent Irritable Bowel Syndrome Symptoms in Patients with Quiescent Inflammatory Bowel Disease

Review article: A practical approach to persistent gastrointestinal symptoms in inflammatory bowel disease in remission

BACKGROUND

Persistent gastrointestinal symptoms are prevalent in adult patients with inflammatory bowel disease (IBD), even when endoscopic remission is reached. These symptoms can have profound negative effects on the quality of life of affected patients and can be difficult to treat. They may be caused by IBD-related complications or comorbid disorders, but they can also be explained by irritable bowel syndrome (IBS)-like symptoms.

AIMS

To provide a practical step-by-step guide to diagnose and treat persistent gastrointestinal symptoms in patients with IBD in remission via a personalised approach.

METHODS

We scrutinised relevant literature on causes, diagnostics and treatment of persistent gastrointestinal symptoms (abdominal pain or discomfort, bloating, abdominal distension, diarrhoea, constipation and faecal incontinence) in patients with IBD in remission.

RESULTS

A graphical practical guide for several steps in diagnosing, identifying potential triggers and adequate treatment of persistent gastrointestinal symptoms in IBD in remission is provided based on supporting literature. The first part of this review focuses on the diagnostic and treatment approaches for potential IBD-related complications and comorbidities. The second part describes the approach to IBS-like symptoms in IBD in remission.

CONCLUSIONS

Persistent gastrointestinal symptoms in IBD in remission can be traced back to potential pathophysiological mechanisms in individual patients and can be treated adequately. For both IBD-related complications and comorbidities and IBS-like symptoms in IBD in remission, pharmacological, dietary, lifestyle or psychological treatments can be effective. A systematic and personalised approach is required to reduce the burden for patients, healthcare systems, and society.

Bone Marrow Mesenchymal Stem Cells (BMSC) Carried with miR-338 Improve BMSC Homing in Intestinal Mucosa of Inflammatory Bowel Disease (IBD) Rats Through Increasing C-X-C Chemokine Receptor Type 4 (CXCR-4)

This study assessed whether bone marrow mesenchymal stem cells (BMSC) carried with miR-338 improve its homing in intestinal mucosa of IBD rats. Fifty SD rats were equally and randomly assigned into control set, model set, miR-338 set, CXCR-4 Inhibitor set and positive control set followed by analysis of miR-338 expression, body weight, DAI grade, pathological changes of distal colonic tissue, ultra-microstructure of intestinal epithelium, level of IL-8, IL-10, TGF-β1, VEGF, and CXCR4, as well as the relation between miR-338 and CXCR-4. miR-338 in decorated BMSC was significantly upregulated. Body weight in model set and CXCR-4 Inhibitor set was lowest followed by miR-338 set and positive control set. However, opposite results were obtained for DAI grade. IL-8 level was highest and IL-10 was lowest in model set and CXCR-4 Inhibitor set. The BMSC carried with miR-338 exerted recovery action on the intestinal mucosa of IBD rats and inhibited the activity of inflammatory cells. In conclusion, BMSC carried with miR-338 develops recovery action on the intestinal mucosa of IBD rats possibly through regulation of CXCR4, indicating that miR-338 might be a target for the treatment of IBD.
