Authors' conclusion

Patients with inflammatory arthritides requiring TNFi therapy use more NSAIDs than matched comparators, and consumption decreased following TNF initiation. Patient-reported measures are not associated with high NSAID use in patients with peripheral arthritis.

Study context

Population
Patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA) in Iceland, 2 years before to 2 years after initiation of a first TNFimatched cohort
Exposure
Patients with inflammatory arthritis initiating a first TNFi vs matched general-population comparators; NSAID use before vs after TNFi initiation
Outcome
NSAID use (filled prescriptions, DDD per year)
Follow-up
2 years before to 2 years after TNFi initiation
Methodological detailsnationwide, matched comparators (5 per patient, on age, sex and calendar time)
  • Nationwide
  • Matched comparators (5 per patient, on age, sex and calendar time)

Further findings

OutcomeValues
NSAID use after TNFi initiationPatients mean 85 DDD per year
axSpA: highest NSAID-use quintile vs other patients, pain (mm), at TNFi initiation (subgroup)Significantly worseHighest NSAID quintile mean 66 (SD 21) mm · Other patients mean 60 (SD 23) mm
axSpA: highest NSAID-use quintile vs other patients, global health (mm), at TNFi initiation (subgroup)Significantly worseHighest NSAID quintile mean 70 (SD 20) mm · Other patients mean 64 (SD 23) mm
axSpA: highest NSAID-use quintile vs other patients, HAQ score, at TNFi initiation (subgroup)Significantly worseHighest NSAID quintile mean 1.21 (SD 0.66) · Other patients mean 1.02 (SD 0.66)
NSAID use after TNFi initiation — Decrease in RA
42%
NSAID use after TNFi initiation — Decrease in PsA
43%
NSAID use after TNFi initiation — Decrease in axSpA
48%

Peripheral arthritis: highest NSAID-use quintile vs other patients (subgroup) · TNFi initiation

No significant differences observed in the groups with peripheral arthritis
