, according to a new study.
“IBD is a distressing condition, and current medication that reduces inflammation is expensive and can have side effects,” said Natasha Seaton, first author and a PhD student at the Institute of Psychiatry, Psychology and Neuroscience (IoPPN) at King’s College London.
“Our study showed that interventions that treat mental health reduce levels of inflammation in the body,” she said. “This indicates that mood interventions could be a valuable tool in our approach to help those with IBD.”
The study was published online in eBioMedicine.
Analyzing Mood Interventions
Ms. Seaton and colleagues conducted a systematic review and meta-analysis of randomized controlled trials in adults with IBD that measured inflammatory biomarker levels and tested a mood intervention, including those aimed at reducing depression, anxiety, stress, or distress or improving emotional well-being.
Looking at data from 28 randomized controlled trials with 1789 participants, the research team evaluated whether mood interventions affected IBD inflammation, particularly IBD indicators such as C-reactive protein and fecal calprotectin, and other general inflammatory biomarkers.
The researchers found mood interventions significantly reduced levels of inflammatory biomarkers, compared with controls, corresponding to an 18% reduction in inflammatory biomarkers.
Psychological therapies had the best outcomes related to IBD inflammation, compared with antidepressants or exercise. These therapies included cognitive behavioral therapy, acceptance and commitment therapy, and mindfulness-based stress reduction.
Individual analyses of IBD-specific inflammatory markers found small but statistically significant reductions in C-reactive protein and fecal calprotectin after a mood intervention. This could mean mood treatments have positive effects on both inflammation and disease-specific biomarkers, the authors wrote.
In addition, interventions that had a larger positive effect on mood had a greater effect in reducing inflammatory biomarkers. This suggests that a better mood could reduce IBD inflammation, they noted.
“We know stress-related feelings can increase inflammation, and the findings suggest that by improving mood, we can reduce this type of inflammation,” said Valeria Mondelli, MD, PhD, clinical professor of psychoneuroimmunology at King’s IoPPN.

“This adds to the growing body of research demonstrating the role of inflammation in mental health and suggests that interventions working to improve mood could also have direct physical effects on levels of inflammation,” she said. “However, more research is needed to understand exact mechanisms in IBD.”
Cost Benefit
Many IBD interventions and medications can be expensive for patients, have significant negative side effects, and have a lower long-term treatment response, the authors noted. Mood interventions, whether psychological therapy or medication, could potentially reduce costs and improve both mood and inflammation.
Previous studies have indicated that psychosocial factors, as well as mood disorders such as anxiety and depression, affect IBD symptom severity and progression, the authors wrote. However, researchers still need to understand the mechanisms behind this connection, including gut-brain dynamics.
Future research should focus on interventions that have been effective at improving mood in patients with IBD, assess inflammation and disease activity at numerous timepoints, and include potential variables related to illness self-management, the authors wrote.
In addition, implementation of mood interventions for IBD management may require better continuity of care and healthcare integration.
“Integrated mental health support, alongside pharmacological treatments, may offer a more holistic approach to IBD care, potentially leading to reduced disease and healthcare costs,” said Rona Moss-Morris, PhD, senior author and professor of psychology at King’s IoPPN.

Medications taken to reduce inflammation can be costly compared with psychological therapies, she said. “Given this, including psychological interventions, such as cost-effective digital interventions, within IBD management might reduce the need for anti-inflammatory medication, resulting in an overall cost benefit.”
