The recent analysis of data included in the Stockholm TNFα Follow- Up (STURE) registry showed that the concomitant use of methotrexate (MTX) with etanercept (ETN), adalimumab or infliximab was associated with long-term drug survival of anti-tumour necrosis factor (TNF) agents in patients with psoriatic arthritis (PsA).1 The positive effect of MTX was primarily linked to fewer drop-outs due to adverse events.1 This analysis did not consider each anti-TNF drug subgroup. For this reason we determined the cumulative probability of taking ETN with or without MTX in a large cohort of patients.

We prospectively studied 82 patients, admitted to our rheumatological unit since 2001, affected by PsA, classified …
