Intra-articular glucocorticoid injections should not be neglected in the remission targeted treatment of early rheumatoid arthritis: a post hoc analysis from the NEO-RACo trial.

OBJECTIVES: To study the effects of neglecting intra-articular glucocorticoid injections (IAGCIs) into swollen joints in early rheumatoid arthritis (RA). METHODS: Ninety-nine patients with early, DMARD naive RA were treated, aiming at remission, with methotrexate, sulfasalazine, hydroxychloroquine, low-dose oral prednisolone and, when needed, IAGCIs for 2 years, and randomised to receive infliximab or placebo from weeks 4 to 26. During each of the 15 study visits, patients were scored retrospectively 0.2-0.4 points (depending on the number of non-injected joints) if IAGCIs to all swollen joints were not given. Patients were divided into tertiles by their cumulative scores for neglected injections (CSNI) over 24 months. 28-joint disease activity score (DAS28) area under the curve (AUC) between 0-24 months, remission rates, changes in quality of life, and radiological changes during the follow-up were assessed. Trends across tertiles of CSNI were tested with generalised linear models. RESULTS: Higher CSNI was associated with lower strict remission rates (p=0.005), and lower quality of life (p=0.004) at 24 months, and higher DAS28 AUC (p<0.001) during the follow-up. At 24 months, DAS28 remission rates were 90%, 93% and 76% (p=0.081), and strict remission rates were 74%, 77% and 39% by tertiles of CSNI. No significant differences were observed in radiological progression (p=0.089). IAGCIs were well tolerated. CONCLUSIONS: Neglecting IAGCIs into swollen joints is associated with lower remission rates, higher disease activity, and lower quality of life. Hence, IAGCIs should be used as an integral part of the targeted treatment of early RA.

Do the 2010 ACR/EULAR or ACR 1987 classification criteria predict erosive disease in early arthritis?

BACKGROUND: The new 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria for rheumatoid arthritis (RA) aim at earlier diagnosis of RA compared to the 1987 ACR criteria. OBJECTIVE: To evaluate the ability of the 2010 ACR/EULAR and the 1987 ACR classification criteria to predict radiographic progression after 10 years of follow-up. METHODS: All early arthritis patients referred to Central Hospital in Jyväskylä from 1997 to 1999 (cases with peripheral joint synovitis, other specific diseases excluded) were included in this 10-year follow-up study. Radiographs of hands and feet were analysed according to Larsen on a scale of 0-100. RESULTS: At 10 years, 58% of the patients had an erosive disease (defined as Larsen ≥2 in at least one joint). The discriminative power of the 2010 ACR/EULAR and the 1987 ACR criteria (erosive disease at 10 years) were comparable, with area under the curve 0.72 (95% CI 0.65 to 0.79) (2010 ACR/EULAR criteria) and 0.65 (95% CI 0.58 to 0.72) (1987 ACR criteria). The respective sensitivities and specificities were 0.87 and 0.70, and 0.44 and 0.47. At 10 years, median (IQR) Larsen score was 6 (0, 15) among patients who had fulfilled both sets of criteria, 2 (0, 8) in those who met the 2010 ACR/EULAR and did not meet the ACR 1987 criteria, 0 (0, 5) in those who met ACR 1987 criteria but did not meet 2010 ACR/EULAR criteria, and 0 (0, 2) among patients who did not fulfil either of the criteria. The percentage of patients with erosions was 69%, 64%, 32% and 26%, respectively. CONCLUSIONS: The ability of the 2010 ACR/EULAR and 1987 ACR classification criteria to identify erosive disease in early arthritis is low. The discriminative power of the 2010 ACR/EULAR criteria of erosiveness in 10 years is slightly better than that of the 1987 ACR criteria.

Infliximab for 6 months added on combination therapy in early rheumatoid arthritis: 2-year results from an investigator-initiated, randomised, double-blind, placebo-controlled study (the NEO-RACo Study).

OBJECTIVE: Early treatment of patients with rheumatoid arthritis (RA) with combination treatment starting with methotrexate, sulfasalazine, hydroxychloroquine and prednisolone (FIN-RACo strategy) is superior to monotherapy. A study was undertaken to determine whether infliximab (INFL) added to intensified FIN-RACo treatment for the initial 6 months improves the 2-year outcome. METHODS: 99 patients with early untreated active RA were enrolled in an investigator-initiated, randomised, double-blind, multicentre, parallel-group trial. Primary outcomes were remission and radiological changes at 2 years. All patients started with FIN-RACo. In addition, they were randomised to receive INFL or placebo (Pla) from weeks 4 to 26. RESULTS: At 24 months, 66% and 53%, respectively, of the patients in the FIN-RACo+INFL and FIN-RACo+Pla groups were in remission according to the modified American College of Rheumatology (ACR) criteria (p=0.19), 26% and 10% were in sustained modified ACR remission (p=0.042) and 82% in both groups were in remission by 28-joint disease activity score (not significant). Mean changes in the total Sharp-van der Heijde score were 0.2 and 1.4, respectively (p=0.0058). CONCLUSIONS: Most patients with early active RA achieve clinical remission and develop negligible joint damage with the intensified FIN-RACo regimen. Adding INFL for the first 6 months delays radiological progression.

Rheumatoid atlantoaxial subluxation can be prevented by intensive use of traditional disease modifying antirheumatic drugs.

OBJECTIVE: To evaluate the 5-year incidence of cervical spine disorders in patients with early rheumatoid arthritis (RA) treated by 2 different disease modifying antirheumatic drug (DMARD) strategies. METHODS: In a national, multicenter, prospective FIN-RACo-trial, a cohort of 199 patients with early, clinically active RA was randomly assigned to treatment with a combination of 3 DMARD and prednisolone (Combi group) or with a single DMARD (Single group) with or without prednisolone, aiming to induce remission. After 2 years, the DMARD therapy was unrestricted. Lateral view cervical spine radiographs during full flexion and extension were taken at the 5-year followup visits. The presence of anterior atlantoaxial subluxation (aAAS), atlantoaxial impaction (AAI), and subaxial subluxation (SAS) was assessed in the 149 patients with radiographs available (80 Single and 69 Combi). RESULTS: At the 5-year visits, aAAS, AAI, and SAS were found in 13 (9%), 6 (4%), and 9 (6%) patients, respectively. The corresponding Single/Combi group ratios were 11/2, 5/1, and 5/4. Of the baseline data, only poor physical function [Health Assessment Questionnaire (HAQ); p = 0.024] and Single treatment strategy (p = 0.019) were significantly associated with aAAS. Worse HAQ scores and Disease Activity Score 28 values were found in patients who developed aAAS during the 5-year followup. CONCLUSION: RA patients with sustained clinical disease activity and poor HAQ are at increased risk of developing aAAS. The development of aAAS during the first 5 years of RA was rare among the patients treated with a combination of DMARD for at least 2 years from the diagnosis. Intensive treatment with traditional DMARD prevents or retards the development of aAAS in patients with recent-onset RA.
