The Efficacy of Short-Term Bridging Strategies With High- and Low-Dose Prednisolone on Radiographic and Clinical Outcomes in Active Early Rheumatoid Arthritis: A Double-Blind, Randomized, Placebo-Controlled Trial.

OBJECTIVE: In active early rheumatoid arthritis (RA), glucocorticoids are often used for bridging, due to the delayed action of methotrexate. This study was undertaken to compare the effect of 3 bridging strategies, including high-dose and low-dose prednisolone, on radiographic and clinical outcomes. METHODS: Adult RA patients from 1 rheumatology hospital and 23 rheumatology practices who presented with moderate/high disease activity were randomized (1:1:1) to receive 60 mg prednisolone (high-dose prednisolone [HDP]) or 10 mg prednisolone (low-dose prednisolone [LDP]) daily (tapered to 0 mg within 12 weeks) or placebo. The 12-week intervention period was followed by 40 weeks of therapy at the physicians' discretion. The primary outcome measure was radiographic change at 1 year measured using the total modified Sharp/van der Heijde score (SHS). Disease activity was assessed with the Disease Activity Score in 28 joints using the erythrocyte sedimentation rate (DAS28-ESR). RESULTS: Of 395 randomized patients (HDP, n = 132; LDP, n = 131; placebo, n = 132), 375 (95%) remained in the modified intention-to-treat analysis. Mean ± SD changes in SHS scores in the 3 groups after 1 year were comparable: mean ± SD 1.0 ± 2.0 units in the HDP group, 1.1 ± 2.2 units in the LDP group, and 1.1 ± 1.5 units in the placebo group. The primary analysis showed no superiority of HDP compared to placebo (estimated difference of the mean change -0.04 [95% confidence interval (95% CI) -0.5, 0.4]). At week 12, the mean DAS28-ESR differed: -0.6 (95% CI -1.0, -0.2) for HDP versus placebo; -0.8 (95% CI -1.2, -0.5) for LDP versus placebo. At week 52, there was no significant difference in DAS28-ESR between the 3 groups (range 2.6-2.8). Serious adverse events occurred similarly often. CONCLUSION: Short-term glucocorticoid bridging therapy at a high dose showed no benefit with regard to progression of radiographic damage at 1 year.

Efficiency of treatment with non-steroidal anti-inflammatory drugs according to current recommendations in patients with radiographic and non-radiographic axial spondyloarthritis.

OBJECTIVE: NSAIDs are first-line therapy in axial SpA (axSpA). The proportion of patients responding to NSAIDs and differences between AS and non-radiographic axSpA (nr-axSpA) in this regard have not been studied in detail to date. The aim of this study was to examine the proportion of patients with AS and nr-axSpA responding to NSAIDs according to current treatment recommendations. METHODS: Consecutive anti-TNF-naïve patients with nr-axSpA and AS (n = 50 each) were included if their BASDAI score was ⩾4 without having received maximal NSAID doses. In case of a BASDAI score ⩾4 1 week later, another NSAID was prescribed. For the next 3 weeks, continuous intake of maximal doses was recommended but patients could reduce doses in case of intolerance or improvement. MRI of the SI joints was performed at baseline and week 4. RESULTS: All outcomes except for CRP and MRI scores improved significantly after 4 weeks of NSAIDs, with no difference between axSpA subgroups. An Assessment of SpondyloArthritis international Society 40% (ASAS40) response and partial remission rates were 35 and 16% at week 4, respectively. At the same time point, a BASDAI score ⩾4 was still present in 44% of patients, 30% of which had reduced NSAID doses, partly due to intolerance (38%). Only 13% of all patients had continuously taken NSAIDs at the maximal dosage, but there was no difference in the efficacy outcome compared with those who had taken reduced doses. CONCLUSION: AS and nr-axSpA patients had similar response rates to NSAIDs while objective signs of inflammation did not change over 4 weeks. Only a minority of patients was willing to take maximal doses of NSAIDs, and ⩾40% patients remained candidates for TNF blockers. These results may influence future trial designs.
