About

Patients with inflammatory rheumatism very often have residual pain that is not easily relieved by conventional treatments. They can then use non-drug methods, such as physiotherapy, hypnosis or even cannabis.

The aim of this study is to assess the percentage of patients who use cannabis to better relieve their pain or anxiety in chronic inflammatory rheumatism.

Full description

Thanks to a better understanding of the pathophysiological mechanisms of inflammatory rheumatism, rheumatology has known for several decades a growth in its therapeutic arsenal (csDMARDs, bDMARDs, tDMARDs). rheumatism control has thus been optimized.

however, patients very often keep pain, anxiety, residual fatigue, poorly controlled by our conventional therapies. patients then turn to non-drug therapies, among which the use of cannabis.

endocannabinoids have an analgesic and anti-inflammatory action recognized in pre-clinical trials. however, investigators currently lack the data to authorize its use in clinical rheumatology.

the aim of this study is to determine the prevalence of cannabis users in patients with rheumatoid arthritis, ankylosing spondyloarthritis or psoriatic arthritis in our unit. as a second intention, investigators will refine the consumption characteristics. Investigators will also look for possible risk factors for consumption (sensitivity to pain, catastrophism, standard of living, anxiety, depression, rheumatic activity and quality of life).
