There were no complications related to arthroscopic surgery. All patients achieved confirmed C-reactive protein normalisation within an average of 69.8 days, and there was no recurrence during the follow-up period (mean, 40.2 months; range, 16-60 months). Arthroscopic management for native acute septic arthritis of the hip joint is a safe and effective procedure in adult patients. Arthroscopic management for native acute septic arthritis of the hip joint is a safe and effective procedure in adult patients. The outcome of rheumatoid arthritis (RA) should be determined early. Rapid radiological progression (RRP) is > or = 5 units increase according to the van der Heijde-Sharp score within a year. The risk of RRP can be estimated by a matrix model using non-radiographic indicators, such as C-reactive protein (CRP), rheumatoid factor (RF) and swollen joint count (SJC). A non-interventional, cross-sectional, retrospective study was conducted in eleven Hungarian arthritis centres. We assessed RRP risk in biologic-naïve RA patients with the prevalence of high RRP risk as primary endpoint. RRP was calculated according to this matrix model. As a secondary endpoint, we compared RRP in methotrexate (MTX) responders vs non-responders. We analyzed data from 1356 patients. Mean CRP was 17.7 mg/l, RF was 139.3 IU/ml, mean 28-joint disease activity score (DAS28) was 5.00 and mean SJC was 6.56. Altogether 18.2% of patients had high risk (≥40%) of RRP. RA patients with high RRP risk of RRP (n= 247) had significantly lower age compared to those with RRP < 40% (n= 1109). MTX non-response (OR 16.84), male gender (OR 1.67), erosions at baseline (OR 1.50) and ACPA seropositivity (OR 2.18) were independent predictors of high-risk RRP. Male gender (OR 5.20), ACPA seropositivity (OR 4.67) and erosions (OR 7.98) were independent predictors of high
