Impact of physicians' adherence to treat-to-target strategy on outcomes in early rheumatoid arthritis in the NEO-RACo trial.

OBJECTIVES: It is well recognized that medication adherence of rheumatoid arthritis (RA) patients is often poor. As less attention has been paid to physicians' adherence to targeted treatment, we aimed to investigate how it affects outcomes in aggressively treated early RA patients. METHOD: In the new Finnish RA Combination Therapy (NEO-RACo) trial, 99 patients with early active RA were treated, targeting remission, with a combination of methotrexate, sulfasalazine, hydroxychloroquine, and low-dose prednisolone for 2 years, and randomized to receive infliximab or placebo for the initial 6 months. After 2 years, therapy was unrestricted while remission was still targeted. Patients were divided into tertiles by physicians' adherence to treat-to-target, which was evaluated with a scoring system during the initial 2 years. After 5 years of follow-up, the between-tertile differences in remission rates, 28-joint Disease Activity Score (DAS28) levels, radiological changes, cumulative days off work, and the use of anti-rheumatic medication were assessed. RESULTS: Follow-up data were available for 93 patients. Physicians' good adherence was associated with improved remission rates at 2-4 years and lower DAS28 levels throughout the follow-up. In a multivariable model, physicians' adherence was the most important predictor of remission at 3 months and 2 years (p < 0.001 for both). Between 2 and 5 years, biologics were used more often in the tertile of low adherence compared with the other two groups (p = 0.024). No significant differences were observed in radiological progression and cumulative days off work. CONCLUSIONS: Physicians' good adherence is associated with improved remission rates and lesser use of biologics in early RA.

Cost of Finnish statutory inpatient rehabilitation and its impact on functional and work capacity of patients with early rheumatoid arthritis: experience from the FIN-RACo trial.

OBJECTIVE: To explore the cost of the statutory inpatient rehabilitation system in Finland and its impact on the functional and work capacity of patients with early rheumatoid arthritis (RA). METHODS: In the Finnish Rheumatoid Arthritis Combination-Therapy trial (FIN-RACo), 195 patients with recent-onset RA, 162 of them available for the work force, were randomly assigned to two different drug treatment strategies for 2 years. Otherwise, the patients received routine multidisciplinary care and, if their functional or work capacity was endangered, were referred to inpatient rehabilitation. After a 5-year follow-up, data on rehabilitation, sick leave, and RA-related disability pensions were obtained from official registers. RESULTS: Of the 162 patients, 49 (30%) underwent inpatient rehabilitation at an average cost of EURO5400. The rehabilitated patients more often worked in white-collar jobs and had more pain and a worse Health Assessment Questionnaire (HAQ) score (1.0 vs. 0.78; p = 0.01) at baseline. Their HAQ scores remained higher throughout follow-up (p<0.001); no change appeared over inpatient periods [mean 0.01; 95% confidence interval (CI) -0.13 to 0.16]. No independent impact of rehabilitation on the HAQ score emerged in an adjusted generalized estimating equations (GEE) model (p = 0.55). Nor did any improvement in work capacity appear: average lost productivity (human capital approach) per patient-year was EURO10 155 (95% CI 6994-14 196) before and EUR 12 839 (95% CI 8589-19 139) after the start of rehabilitation. CONCLUSION: For patients with recent-onset RA, the Finnish statutory inpatient rehabilitation system had no positive impact on either functional or work capacity during the first few years, despite its considerable cost.

Classic disease modifying anti-rheumatic drugs (DMARDs) in combination with infliximab. The Finnish experience.

To assess the performance of infliximab in a clinical setting, 364 rheumatoid arthritis (RA) patients from the National Register of Biological Treatment in Finland (ROB-FIN) were analysed. Corticosteroid usage and dose diminished (p<0.05 and 0.001, respectively) in patients on infliximab, of whom 51% also used one, 28% two and 16% three other concomitant DMARDs. A 34% of the RA patients used methotrexate+/-corticosteroids without any other DMARD. Methotrexate was most frequently used with sulphasalazine and/or hydroxychloroquine. Non-methotrexate patients most frequently used leflunomide or azathioprine combined with corticosteroids. The clinical effect of these combinations was similar to that of infliximab with methotrexate alone. The results indicate that infliximab can be used together with other DMARDs than methotrexate alone, quite according to the philosophy of the combination drug therapy, as the effectiveness is as good as or even slightly better than that of methotrexate and infliximab.

Predictors of productivity loss in early rheumatoid arthritis: a 5 year follow up study.

OBJECTIVE: To explore baseline risk factors for productivity loss and work disability over 5 years in patients with early, active RA. PATIENTS AND METHODS: In the FIN-RACo trial, 195 patients with recent onset RA were randomised to receive either a combination of DMARDs with prednisolone or a single DMARD for 2 years. At baseline, 162 patients were working or available for work. After 5 years' follow up, data on sick leave and retirement were obtained from social insurance registers or case records. The cumulative duration of sick leaves and RA related disability pensions was counted for each patient. To analyse predictors of productivity loss, the patients were divided into four groups according to duration of work disability per patient year. RESULTS: Patient's and physician's global assessment of RA severity > or =50 and HAQ score > or =1.0 were risk factors for extension of productivity loss (OR (95% (CI) 1.77 (1.00 to 3.16), 1.85 (1.03 to 3.32), and 1.78 (1.01 to 3.14), respectively). Additional risk factors were low education level (2.40 (1.18 to 4.88)) and older age (1.03 (1.00 to 1.06)); combination treatment was a protective factor (0.59 (0.35 to 0.99)). CONCLUSION: At baseline, the risk of future productivity loss is best predicted by education level, age, global assessments of RA severity, and HAQ score.

Comparison of combination therapy with single-drug therapy in early rheumatoid arthritis: a randomised trial. FIN-RACo trial group.

BACKGROUND: The treatment of rheumatoid arthritis should aim at clinical remission. This multicentre, randomised trial with 2-year follow-up sought evidence on the efficacy and tolerability of combination therapy (sulphasalazine, methotrexate, hydroxychloroquine, and prednisolone) compared with treatment with a single disease-modifying antirheumatic drug, with or without prednisolone, in the treatment of early rheumatoid arthritis. METHODS: 199 patients were randomly assigned to two treatment groups. 195 started the treatment (97 received combination and 98 single drug therapy). Single-drug therapy in all patients started with sulphasalazine; in 51 patients methotrexate was later substituted. Oral prednisolone was required by 63 patients. The primary outcome measure was induction of remission. Analyses were intention to treat. FINDINGS: 87 patients in the combination group and 91 in the single-therapy group completed the trial. After a year, remission was achieved in 24 of 97 patients with combination therapy, and 11 of 98 with single-drug therapy (p=0.011). The remission frequencies at 2 years were 36 of 97 and 18 of 98 (p=0.003). Clinical improvement (American College of Rheumatology criteria of 50% clinical response) was achieved after 1 year in 68 (75%) patients with combination therapy, and in 56 (60%) using single-drug therapy (p=0.028), while at the 2-year visit 69 and 57 respectively (71% vs 58%, p=0.058) had clinically improved. The frequencies of adverse events were similar in both treatment groups. INTERPRETATION: Combination therapy was better and not more hazardous than single treatment in induction of remission in early rheumatoid arthritis. The combination strategy as an initial therapy seems to increase the efficacy of the treatment in at least a proportion of patients with early rheumatoid arthritis.
