Objective. The aim of this study was to examine the occurrence of repair in a cohort of conventionally treated patients with early rheumatoid arthritis over 8 years.

Methods. There were 395 patients included in the BARFOT study having radiographs of hands and feet at inclusion, and at 1, 2, 5, and 8 years, which were chronologically scored for erosions by the Sharp/van der Heijde method. An erosion with repair was defined as an erosion that has become partially or totally filled, with or without sclerosis.

Results. Erosions with repair were observed in 64 patients (16%) at 1 year, 113 (29%) at 2 years, 142 (36%) at 5 years, and 200 (51%) at 8 years. At the 1-year visit, 13% of the patients with at least 1 new erosion showed repair versus 3% of the patients with no new erosions (p = 0.001). At 2, 5, and 8 years the corresponding figures were 22% and 6%, 28% and 8%, and 39% and 11%, respectively (all p = 0.001). The sum of all repaired erosions correlated strongly with the sum of all erosions and with the sum of all erosion scores (ρ = 0.79 and 0.77). Presence of rheumatoid factor (RF) and anticyclic citrullinated peptide antibodies (anti-CCP) was significantly associated with both new erosions and repair.

Conclusion. Repair was more common than previously described. The frequency of repair increased over time and was associated with the number of erosions. RF- and anti-CCP–positivity, patient age, and presence of erosions at baseline were independent predictors of repair.
