Background Prognosis of rheumatoid arthritis (RA) should be assessed early during the disease course. Rapid radiological progression (RRP) has been defined as a ≥% unit increase in van der Heijde-Sharp score within a year. The matrix risk model has been developed by Vastesaeger et al in 2009. This tool calculates RRP based on non-radiographic indicators such as baseline CRP, RF and swollen joint count.

Objectives We wished to test the matrix prediction model int he very first Hungarian cohort study.

Methods In this non-interventional, cross-sectional retrospective study carried out in 11 Hungarian arthritis centres, we assessed high risk (≥40%) of RRP in biologic-naive RA patients with active disease. In order to obtain a representative sample, patients were selected from each centre by a random technique. RRP was calculated according to the matrix model described by Vastesaeger et al. As a secondary endpoint, we compared methotrexate (MTX) responders vs non-responders with respect to RRP.

Results We screened data of 1843 RA patients. Finally, data obtained from 1356 patients could be used for RRP prediction and MTX responsiveness. The mean age of patients was 55.5 years, 84.7% were women. The mean disease duration was 8.4 years. At the time of the assessment, mean CRP was 17.7 mg/l, RF was 139,3 IU/ml, mean DAS28 was 5.00 and mean swollen joint count was 6.56. High risk ((≥40%) of RRP could be determined in 18.2% of patients. Among continuous variables other than those used for calculation of RRP risk, RA patients with the risk of RRP≥40% (n=247) had significantly lower age than those with RRP<40% (n=1109) (53.33±12.31 vs 56.02±13.50 years; p=0.001). With respect to binary variables, the risk of RRP≥40% was significantly associated with non-response to MTX (OR: 17.82), male gender (OR: 1.53), ACPA positivity (OR: 2.11), the presence of erosions (OR: 1.37) and current smoking (OR: 1.66). Binary logistic regression analysis revealed that MTX non-response (OR: 16.84), male gender (OR: 1.67) and ACPA positivity (OR: 2.18) were independent predictors of high-risk RRP (≥40%). With regards to MTX responsiveness, binary logistic regression analysis confirmed that both male gender (OR: 5.20) and the presence of erosions (OR: 7.98) were independent predictors of high RRP risk in the MTX responder subpopulation.

Conclusions In the first bioloigc-naive Hungarian RA cohort assessed for RRP, RRP occurs in almost one-fifth of the patients. These patients differ from others in various clinical and serological parameters. RRP has also been associated with non-response to MTX.
