Comparative StudyUltrasound assessment of enthesis thickening in psoriatic arthritis patients treated with adalimumab compared to methotrexate.
The objective of the study was to combine ultrasonographic (US) with clinical findings for comparing the effect of adalimumab (ADA) to methotrexate (MTX) on the thickness of tendons and enthesis in psoriatic arthritis (PsA) patients. Forty-three consecutive PsA patients were examined at baseline and after 6 and 12 weeks of treatment with ADA or MTX. The US assessment included thickness measurement of the extensor (ET) and flexor tendons (FT) of the second and third finger of both hands, plantar aponeurosis (PA) and the Achilles tendon (AT) bilaterally. ⋯ ADA patients showed a trend towards a better response to treatment compared to MTX patients that reach significance at week 6 of treatment for the thickness of left AT (p = 0.04), left PA (p = 0.03), the number of TJ (p = 0.0136), PAI (p = 0.0028), and PDAI (p = 0.029). ADA treatment for PsA compared to MTX significantly improved signs of DA and several US parameters. US assessment of enthesis can be an additional useful tool in the monitoring of psoriatic enthesopathy.
