What this trial studies

This observational study investigates the impact of phytocannabinoids, such as cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC), on the immune response and autophagy in patients with chronic immune-mediated inflammatory diseases. By collecting blood samples as part of routine care, the study aims to explore how these compounds may modulate inflammation and immune function through their interaction with the endocannabinoid system. The research focuses on conditions like rheumatoid arthritis, spondyloarthritis, and inflammatory bowel diseases, assessing the potential therapeutic benefits of phytocannabinoids in these populations.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with confirmed diagnoses of rheumatoid arthritis, spondyloarthritis, psoriatic arthritis, systemic lupus erythematosus, or Sjögren's disease.

Not a fit: Patients currently using high doses of corticosteroids or those consuming CBD or recreational cannabis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide new insights into the use of phytocannabinoids as a treatment option for patients with chronic inflammatory diseases.

How similar studies have performed: While there is emerging evidence supporting the anti-inflammatory effects of phytocannabinoids, this specific approach remains novel and has not been extensively tested in similar studies.
