This study found no difference in objective stress (cortisol) between inflammatory bowel disease (IBD) relapse and remission. However, pro-inflammatory cytokines IL-6 and IL-8 were higher during relapse, suggesting a link between inflammation and IBD activity.
Area of Science:
- Gastroenterology
- Immunology
- Psychoneuroendocrinology
Background:
- The relationship between stress and inflammatory bowel disease (IBD) course requires further investigation.
- Existing research lacks clarity on subjective versus objective stress and stress levels during IBD relapse versus remission.
Purpose of the Study:
- To investigate patients' stress levels during active IBD relapse and remission.
- To compare subjective and objective stress measurements in IBD patients.
Main Methods:
- Twenty-three active IBD patients provided saliva and blood samples for cortisol and cytokine analysis.
- Patients completed the Short Health Scale (SHS) and Perceived Stress Scale (PSS) questionnaires.
- Measurements were taken during relapse and remission, with disease activity confirmed by endoscopy and fecal calprotectin.
Main Results:
- No significant difference in salivary cortisol or PSS scores between relapse and remission.
- Significantly lower levels of inflammatory cytokines IL-6 and IL-8 were observed during remission compared to active disease (p < 0.05 and p < 0.001, respectively).
Conclusions:
- Patients with IBD reported low to moderate perceived stress during both active disease and remission.
- Elevated pro-inflammatory cytokines (IL-6, IL-8) were found during IBD relapse, but objective stress markers (cortisol) did not differ.
- Further research is necessary to elucidate the stress-IBD association and its impact on patients.

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
