Spondyloarthritis & psoriatic arthritis

The association between cigarette smoking and radiographic progression in Psoriatic Arthritis

Semin Arthritis RheumPublished Prospective cohort study

Authors' conclusion

Cigarette smoking does not appear to be significantly associated with the progression of joint damage in PsA.

Study context

Population
Patients with psoriatic arthritis (PsA) from an observational cohort (54.9% male; mean age 44.9 years)308 missing smoking data
Participants
1,736 patients
Exposure
Current or past smoking vs non-smoking
  • Non-smokersn = 906reference
  • Past smokersn = 211
  • Current smokersn = 311
Outcome
Change in radiographic joint damage (modified Steinbrocker score)
Methodological detailsobservational cohort, linear mixed models

Observational data: associations, not effects.

Further findings

Factors associated with increased joint damage (multivariable model)

Longer duration between first and last radiographs, higher baseline modified Steinbrocker score and csDMARD use significantly associated with increased joint damage
