Introduction

Management of Crohn’s Disease involves the suppression of inflammation through administration of immunosuppressive drugs. While conventional therapies such as corticosteroids and thiopurines exert a broad effect on the immune system, the advent of biological agents has allowed for selective targeting of cytokines and integrins.

Unfortunately, a third of patients treated with tumour necrosis factor (TNF) antagonists demonstrate a primary non-response, with another third developing either secondary failure or intolerance. These patients will then have a lower chance of responding to treatment with other TNF antagonists or with the integrin antagonist vedolizumab.

Introduction

Inflammatory Bowel Disease (IBD) comprises a heterogeneous group of chronic inflammatory disorders with two main conditions, Crohn’s Disease (CD) and Ulcerative Colitis (UC) [1]. Bile acid malabsorption (BAM) and bile acid diarrhoea (BAD) have been recognised to be a common cause of chronic diarrhoea, and this recognition has led to the initiation of a search for new screening tests (biomarkers). BAM is one of the mechanisms leading to microscopic colitis, a key factor in the pathogenesis of irritable bowel syndrome-diarrhoea, and molecular mechanisms of BAM are found in IBD patients with or without involvement of the terminal ileum. BAM/BAD is more frequently found in CD than in UC, and the obvious aetiology for BAM in CD is either ileal resection or ileal disease [2]. The pathophysiology of diarrhoea in CD is multifactorial but there are two key factors, colonic water and electrolyte absorption, which can be impaired directly by colonic inflammation or indirectly by increased concentrations of bile acids having secretory effects, referred to as BAD [3].

Introduction

There has been a recent shift in Crohn’s Disease (CD) management away from the conventional focus on short-term clinical outcomes and towards the maintenance of long-term remission.  In 2015 the International Organisation for the Study of Inflammatory Bowel Diseases released a consensus statement recommending a treat-to-target approach [1]. The STRIDE initiative recommended pursuing treatment escalation in order to achieve the treatment targets of clinical remission and mucosal healing, with adjunctive use of normal C-reactive protein (CRP) and faecal calprotectin (FC) levels. However, the authors noted that prospective studies would be needed to confirm that achievement of these targets would alter the natural history of disease and improve patients’ quality of life.
