Study Finds Mood Interventions Can Improve Inflammatory Biomarkers in Inflammatory Bowel Disease

Reading Time: 2 minutes

A new meta-analysis has revealed that interventions targeting mood disorders can lead to significant reductions in inflammatory biomarkers in individuals with inflammatory bowel disease (IBD). The study, conducted by researchers from King’s College London, underscores the potential of psychological therapies to enhance the physical health of IBD patients by addressing mental health issues such as depression and anxiety. The findings were published in the journal eBioMedicine.

Inflammatory bowel disease, which includes Crohn’s disease and ulcerative colitis, is characterised by chronic inflammation of the gastrointestinal tract. This condition often leads to debilitating physical symptoms and poses significant psychosocial challenges, with high rates of depression and anxiety among sufferers. The connection between mental health and IBD symptom severity has been previously observed, but the specific impact of mood interventions on inflammation has remained unclear.

The meta-analysis, which included 28 randomised controlled trials with a total of 1,789 participants, aimed to fill this gap by evaluating the effect of mood-targeting interventions on inflammatory biomarkers such as C-Reactive Protein (CRP) and faecal calprotectin. These biomarkers are critical indicators of disease activity in IBD.

The findings revealed that interventions designed to improve mood had a small but statistically significant effect on reducing biomarkers of inflammation. The overall effect size was –0.35 for inflammatory biomarkers and –0.50 for mood outcomes, indicating moderate improvements in mood and small reductions in inflammation. Specifically, psychological therapies demonstrated a greater impact on reducing inflammatory biomarkers compared to other interventions like exercise or antidepressants.

For instance, interventions showed an effect size of –0.19 for faecal calprotectin and –0.29 for CRP, both statistically significant reductions. These results suggest that improvements in mood may directly influence the immune system and reduce inflammation through psychoneuroimmunological pathways.

The study highlights the importance of integrating mental health support with conventional medical treatments for IBD. Psychological therapies, particularly those that effectively improve mood, could serve as a complementary strategy to reduce inflammation and improve overall disease outcomes. This holistic approach may not only enhance the quality of life for patients but also reduce healthcare costs associated with IBD management.

The findings support the integration of mental and physical healthcare in the treatment of IBD. Psychological interventions that effectively improve mood have the potential to reduce inflammation and improve disease outcomes, offering a more comprehensive approach to patient care.

Despite the promising results, the study acknowledges the need for further research to understand the underlying mechanisms that link mood improvements with reduced inflammation. Future studies should investigate the specific biological or behavioural pathways that mediate these effects and identify which psychological constructs are most influential.

Additionally, the study calls for more research to determine the optimal timing and types of interventions that are most effective in managing both the mental and physical aspects of IBD. Understanding these factors could lead to more tailored and effective treatment plans for patients.
