What this Trial Is About
This research aims to explore how phytocannabinoids, natural molecules from the cannabis plant, affect the immune system and autophagy in people with chronic immune-mediated inflammatory diseases (IMIDs). These diseases, including rheumatoid arthritis, spondyloarthropathy, psoriatic arthritis, Sjogren's disease, and systemic lupus erythematosus, involve inflammation caused by immune system imbalance. The study focuses on identifying the most effective chemical profiles of phytocannabinoids to influence these inflammatory conditions. The study involves collecting a single 40 mL blood sample from 100 patients with these IMIDs during routine care. Blood cells will be exposed in the lab to different full-spectrum phytocannabinoid extracts, including CBD-dominant with low THC, THC-dominant, balanced THC/CBD, and CBG-dominant extracts. Inflammatory inducers will be used alone and with these extracts, alongside a known anti-inflammatory drug as a control, to assess their effects on immune cell responses. Participants will provide consent and have blood collected once. Researchers will analyze inflammatory markers, cannabinoid receptor expression, and genes related to autophagy and apoptosis in blood cells. The main goal is to understand how different phytocannabinoid mixtures affect the inflammatory profile of immune cells. This cross-sectional study does not involve ongoing treatment or follow-up, focusing instead on lab-based immune response measures.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person) including consent and eligibility verification with a saliva test
Duration - One-time procedure at inclusion
Participants provide an additional 40 mL blood sample during a routine blood test for research purposes. Blood cells from participants are exposed in vitro to various inflammatory inducers and different phytocannabinoid extracts to evaluate biological and immunological effects.
