Abstract

BACKGROUND: Inflammatory bowel disease (IBD) causes fatigue, pain and faecal urgency/incontinence symptoms. Identifying symptom profile subgroups and related psychological correlates might enable earlier intervention and more effective tailored treatment pathways.

METHODS: This study was nested within a randomised controlled trial of a digital symptom intervention for people with IBD (n=780). Latent profile analysis (LPA) was conducted on pre-randomisation baseline measures of fatigue, pain, and faecal incontinence. Multinominal logistic regression examined associations between profile membership and clinical, demographic and psychological factors.

RESULTS: LPA determined a three-profile model: Moderate (50%), High (40%) and Severe symptoms (10%). Diagnosis and faecal calprotectin were not associated with profile membership, but female gender, comorbidity, time since diagnosis and IBS-type symptoms were associated with High and Severe symptoms profiles. Depression, anxiety, negative symptom perceptions, all-or-nothing and avoidance behaviours significantly increased the relative risk of High and Severe symptoms profile membership.

CONCLUSIONS: Many participants experienced symptoms even when deemed to be in clinical remission. After controlling for clinical, inflammatory, and demographic factors, the relative risk of High or Severe symptom profile membership was associated with potentially modifiable cognitive behavioural factors. These factors were also associated with IBS-type symptoms. Recognising the potential impact of cognitive behavioural factors in exacerbating symptoms can lead to earlier identification of patients who require support and allows treatment plans to be tailored more precisely. The findings from this study promote a more integrated approach to IBD management, combining medical treatment with cognitive behavioural interventions to enhance patient care and improve outcomes.
