Treatment of psychological co-morbidities in common gastrointestinal and hepatologic disorders

Abstract

Anxiety and depressive disorders frequently coexist with gastrointestinal and hepatologic conditions. Despite their high prevalence, approach to treating these co-morbidities is not always straightforward. This paper aims to review the current literature into etiology of psychological co-morbidities and their treatment in three conditions commonly encountered at gastroenterology outpatient clinics, namely inflammatory bowel disease (IBD), irritable bowel syndrome (IBS) and chronic hepatitis C (HepC). The paper demonstrates that although psychotherapy (and cognitive-behavioural therapy in particular) has been established as an effective treatment in IBS, more studies are needed in HepC and IBD. Antidepressants have been recognized as an effective treatment for psychological and somatic symptoms in IBS and for depression in HepC, but good quality studies in IBD are lacking despite the promising preliminary findings from animal models and case studies. Further studies in this area are needed.
