Show moreOBJECTIVE: Only 31% of Dutch rheumatoid arthritis (RA)-patients visit a rheumatologist within 12 weeks after symptom onset; this is mainly due to delay at the level of the general practitioner (GP). In order to reduce delay of GPs in identifying early arthritis, we initiated an Early Arthritis Recognition Clinic (EARC). METHODS: EARCs were initiated at the Leiden and Groningen University Medical Centers. At this EARC, patients filled in a questionnaire about their symptoms, followed by a short visit with only a full joint examination by an experienced rheumatologist. If arthritis was present the patient got an appointment the same week at the regular outpatient clinic. The main outcome parameter was the GP-delay; the secondary outcome parameter was the total delay. In both centres, patients included in early arthritis clinics that had arrived via regular referrals served as control group. RESULTS: Four hundred patients visited the Leiden EARC and 212 patients the Groningen EARC. Arthritis was detected in 42% and 49% respectively. The median GP-delay for these arthritis patients was 2.0 (0.4-7.3) and 2.0 (0.4-10.0) weeks and the median total delay 8.6 (3.6-22.3) and 10.6 (3.1-30.8) weeks respectively. At these two clinics 59% and 51% of all arthritis patients and 65% and 53% of the patients that were subsequently diagnosed with undifferentiated arthritis or RA were seen within 12 weeks after symptom onset. In the Leiden and Groningen control groups that arrived via regular referrals, only 32% and 38% were seen within 12 weeks time. CONCLUSIONS: The EARC increased the early identification of arthritis and RA. Show less

Show moreObjective. To determine the prevalence of large-joint damage and the association with small-joint damage in patients with RA after 8 years of low DAS (≤2.4)-targeted treatment with different treatment strategies.Methods. Radiological data of 290 patients participating in the BeSt study, a randomized trial comparing initial monotherapy and initial combination therapy strategies, were used. Radiographs of large joints were scored using the Larsen score and of the small joints using the Sharp-van der Heijde score. With multivariate logistic regression analysis, an association between total damage of the small joints and of the large joints was investigated.Results. After 8 years of treatment, damage was observed in 12% of shoulders, 10% of elbows, 26% of wrists, 13% of hips, 18% of knees and 7% of the ankles. Damage in one or more large joints was found in 64% of patients, with a median score of 1. No difference was found between initial monotherapy or combination therapy strategies. There was a significant association between damage progression in small joints and damage to one or more large joints (OR 1.02; 95% CI 1.00-1.04).Conclusion. After 8 years of DAS-targeted treatment in early RA patients, large-joint damage was found in 64% of patients and was associated with small-joint damage. Continued DAS-targeted treatment is probably more important in damage suppression than initial treatment strategy. Patients with more damage to hands and feet also have more damage to the large joints. Show less
OBJECTIVE: To evaluate the contribution of joint space narrowing (JSN) and erosions in general and in four different joint groups in relation to physical disability in rheumatoid arthritis (RA).... Show moreOBJECTIVE: To evaluate the contribution of joint space narrowing (JSN) and erosions in general and in four different joint groups in relation to physical disability in rheumatoid arthritis (RA). METHODS: 5-year follow-up data from the Behandel Strategieën (BeSt) trial were used, where 508 patients with recent onset RA were treated aiming at a disease activity score ≤2.4. Joint damage was assessed annually and scored according to the Sharp-van der Heijde method. Physical disability was measured 3-monthly with the Health Assessment Questionnaire (HAQ). Generalised Estimating Equations analyses were performed to assess the relationship between the HAQ and JSN scores and erosions scores, separately and in joint groups. RESULTS: Overall, damage scores were low, and neither total JSN nor erosions showed a significant effect on HAQ (β=0.001 95% CI -0.003 to 0.004 and β=0.002 95% CI -0.001 to 0.006, respectively). Of the total damage scores per joint group, damage in the wrist shows a trend for association with physical disability displaying the largest effect size (β=0.005 95% CI 0.000 to 0.011). Also in the analysis with erosions per joint group, the wrist was most strongly related with physical functioning (β=0.016 95% CI 0.003 to 0.029); in the analysis with JSN per joint group no joint group was significantly related to the HAQ. Analysis of all erosion and narrowing scores per joint group in one model reveals only erosions in the wrist to be independently associated with impaired physical functioning (β=0.017 95% CI 0.003 to 0.030). CONCLUSIONS: Joint damage in the wrist, erosions more than JSN, is associated with impaired physical functioning even in patients with early RA with limited overall damage after 5 years tightly controlled treatment.

Show moreObjective: Personalized treatment depends on the treatment goals. Current prediction models to guide initial treatment choices focus on radiological damage progression. However, for some patients this outcome is less relevant, whereas short-term functional ability is relevant to all. Do these various treatment goals share the same predictors? Methods: Data for 497 patients from the Dutch Behandel Strategieen (BeSt) study of treatment strategies for early rheumatoid arthritis (RA), randomized to initial monotherapy or combination therapy, were used. Predictors of short-term functional disability [Health Assessment Questionnaire (HAQ) score ≥ 1 after 3 months of treatment] were identified with logistic regression analyses. Predicted risks of a HAQ score ≥ 1 were determined for each treatment group and for each subpopulation. Results: At baseline, 76% of patients had a HAQ score ≥ 1 (mean 1.7 ± 0.5). After 3 months of treatment this score was achieved by 40% (mean HAQ score 1.5 ± 0.5). Baseline HAQ score, pain, the Ritchie Articular Index (RAI), and treatment group were significant independent predictors for a HAQ score ≥ 1; the presence of rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibodies, and baseline radiological damage were not. With cut-offs of 35% and 60%, the risk of a HAQ score ≥ 1 was high for 47% and low for 20% of the patients treated with initial monotherapy. Risks were markedly reduced in the combination therapy groups, also in unfavourable risk profiles. Conclusion: In recent-onset active RA, baseline HAQ score, pain, and initial treatment are predictors for a HAQ score ≥ 1 after 3 months. Known predictors of radiological damage were not predictive of short-term functional disability. The choice of the best initial treatment thus depends on the relevance of various outcome measures for an individual patient. Show less

Show moreOBJECTIVE: Anticitrullinated protein antibodies (ACPAs) are suggested to identify different subsets of patients with rheumatoid arthritis (RA). The authors compared the clinical and radiological responses to Disease Activity Score (DAS)-steered treatment in patients with RA positive or RA negative for ACPA.METHODS: In the BehandelStrategieën (BeSt) study, 508 patients with recent-onset RA were randomised to four treatment strategies aimed at a DAS ≤2.4. Risks of damage progression and (drug-free) remission in 8 years were compared for ACPA-positive and ACPA-negative patients using logistic regression analysis. Functional ability and DAS components over time were compared using linear mixed models.RESULTS: DAS reduction was achieved similarly in ACPA-positive and ACPA-negative patients in all treatment strategy groups, with a similar need to adjust treatment because of inadequate response. Functional ability and remission rates were not different for ACPA-positive and ACPA-negative patients. ACPA-positive patients had more radiological damage progression, especially after initial monotherapy. They had a lower chance of achieving (persistent) drug-free remission.CONCLUSION: Clinical response to treatment was similar in ACPA-positive and ACPA-negative patients. However, more ACPA-positive patients, especially those treated with initial monotherapy, had significant radiological damage progression, indicating that methotrexate monotherapy and DAS- (≤2.4) steered treatment might be insufficient to adequately suppress joint damage progression in these patients.

Show moreObjective To compare nine disease activity indices and the new American College of Rheumatology (ACR)/European League against Rheumatism (EULAR) remission criteria in rheumatoid arthritis (RA) and to relate these to physical function and joint damage progression. Methods Five-year data from the BeSt study were used, a randomised clinical trial comparing four treatment strategies in 508 patients with recent-onset RA. Every three months disease activity was assessed with nine indices (Disease Activity Score (DAS), DAS-C reactive proteine (DAS-CRP), Disease Activity Score in 28 joints (DAS-28), DAS28-CRP, Simplified Disease Activity Index (SDAI), Clinical Disease Activity Index (CDAI) and three DAS versions with adjusted tender joint scores) and categorized into remission, low, moderate and high disease activity (LDA, MDA, HDA). In addition, the recent ACR/EULAR clinical trial and practice remission was assessed 3-monthly with 28 and 68/66 joint counts. For each index, Generalized Estimating Equations analyses were performed to relate disease activity levels and the absence/presence of remission to 3-monthly assessments of physical functioning and annual radiological progression. Results From the composite indices, CDAI and SDAI were the most stringent definitions of remission and classified more patients as LDA. DAS28 and DAS28-CRP had the highest proportions of remission and MDA and a smaller proportion of LDA. ACR/EULAR remission percentages were comparable to CDAI/SDAI: remission percentages. The variant including CRP and 68/66 joint counts was the most stringent. For all indices, higher levels of disease activity were associated with decreased physical functioning and more radiological damage progression. Despite differences in classification between the indices, no major differences in relation to the two outcomes were observed. Conclusion The associations of nine composite indices and ACR/EULAR remission criteria with functional status and joint damage progression showed high accordance, whereas the proportions of patients classified in the disease activity levels differed.
