To explore non-steroidal anti-inflammatory drug (NSAID) and analgesic use in early rheumatoid arthritis (eRA) patients with a favourable risk profile initiating methotrexate (MTX) with or without glucocorticoid (GC) bridging.
Patients with eRA (≤1 year) and favourable risk profile (no erosions, negative rheumatoid factor and anticitrullinated protein antibodiesor low disease activity) in the 2-year CareRA trial were randomised to MTX 15 mg with a step-down GC scheme (COBRA Slim), or MTX without oral GCs, Tight-Step-Up (TSU). Used analgesics were recorded, including frequency, start/end date and indication. Chronic intake (≥90 consecutive days in trial) of NSAIDs, acetaminophen, opioids including tramadol and antidepressants for the indication of musculoskeletal (MSK) pain was considered. Treatments were compared using χ
In total, 43 patients were randomised to COBRA Slim and 47 to TSU. At study inclusion, 33/43 (77%) of patients in the COBRA Slim and 32/47 (68%) in the TSU arm had been using analgesics (p=0.5). During the trial, 67 NSAID and analgesics were used for MSK pain in 26/43 (60%) COBRA Slim patients of which 9/43 (21%) daily chronically (DC), while 107 NSAID and analgesics were used in 43/47 (92%) TSU patients, of which 25/47 (53%) DC. The total number of patients on NSAID and analgesics at any time during the study (p<0.01) and chronically (p=0.01) was significantly different between treatment arms. Number of patients on DC NSAIDs was also significantly different (p<0.01) between COBRA Slim 6/43 (14%) and TSU 19/47 (40%).
NCT01172639.
In eRA patients considered to have a favourable prognosis, initial oral GC bridging resulted in lower chronic NSAID and analgesic use.
