Influence of Social Support, Financial Status, and Lifestyle on the Disparity Between Inflammation and Disability in Rheumatoid Arthritis.

OBJECTIVE: To investigate how social support, financial status, and lifestyle influence the development of excess disability in rheumatoid arthritis (RA). METHODS: Data were obtained from the Étude et Suivi des Polyarthrites Indifférenciées Récentes (ESPOIR) cohort study of people with RA. A previous analysis identified groups with similar inflammation trajectories but markedly different disability over 10 years; those in the higher disability trajectory groups were defined as having "excess disability." Self-reported data regarding contextual factors (social support, financial situation, lifestyle) were obtained from participants, and they completed patient-reported outcome measures (pain, fatigue, anxiety, depression) at baseline. The direct effect of the contextual factors on excess disability and the effect mediated by patient-reported outcome measures were assessed using structural equation models. Findings were validated in 2 independent data sets (Norfolk Arthritis Register [NOAR], Early Rheumatoid Arthritis Network [ERAN]). RESULTS: Of 538 included ESPOIR participants (mean age ± SD 48.3 ± 12.2 years; 79.2% women), 200 participants (37.2%) were in the excess disability group. Less social support (ß = 0.17 [95% confidence interval (95% CI) 0.08, 0.26]), worse financial situation (ß = 0.24 [95% CI 0.14, 0.34]), less exercise (ß = 0.17 [95% CI 0.09-0.25]), and less education (ß = 0.15 [95% CI 0.06, 0.23]) were associated with excess disability group membership; smoking, alcohol consumption, and body mass index were not. Fatigue and depression mediated a small proportion of these effects. Similar results were seen in NOAR and ERAN. CONCLUSION: Greater emphasis is needed on the economic and social contexts of individuals with RA at presentation; these factors might influence disability over the following decade.

Evaluation of the impact of a nurse-led program of patient self-assessment and self-management in axial spondyloarthritis: results of a prospective, multicentre, randomized, controlled trial (COMEDSPA).

OBJECTIVE: To evaluate the impact of a nurse-led program of self-management and self-assessment of disease activity in axial spondyloarthritis. METHODS: Prospective, randomized, controlled, open, 12-month trial (NCT02374749). Participants were consecutive axial spondyloarthritis patients (according to the rheumatologist) and nurses having participated in a 1-day training meeting. The program included self-management: educational video and specific video of graduated, home-based exercises for patients; and self-assessment: video presenting the rationale of tight monitoring of disease activity with composite scores (Ankylosing Spondylitis Disease activity Score, ASDAS/Bath Ankyslosing Spondylitis Disease Activity Index, BASDAI). The nurse trained patients to collect, calculate and report (monthly) ASDAS/BASDAI. Treatment allocation was by random allocation to this program or a comorbidities assessment (not presented here and considered here as the control group). RESULTS: A total of 502 patients (250 and 252 in the active and control groups, respectively) were enrolled (age: 46.7 (12.2) years, male gender: 62.7%, disease duration: 13.7 (11.0) years). After the one-year follow-up period, the adherence to the self-assessment program was considered good (i.e. 79% reported scores >6 times). Despite a lack of statistical significance in the primary outcome (e.g. coping) there was a statistically significant difference in favor of this program for the following variables: change in BASDAI, number and duration of the home exercises in the active group, and physical activity (international physical activity score, IPAQ). CONCLUSION: This study suggests a short-term benefit of a nurse-led program on self-management and self-assessment for disease activity in a young axial spondyloarthritis population in terms of disease activity, exercises and physical activity.

An e-health interactive self-assessment website (Sanoia®) in rheumatoid arthritis. A 12-month randomized controlled trial in 320 patients.

INTRODUCTION: Sanoia is an online interactive electronic e-health platform developed to allow patient self-assessment and self-monitoring. The objective was to assess in rheumatoid arthritis (RA) patients, the efficacy on patient-physician interactions, of giving access to Sanoia. METHODS: In this French, multi-center, 12-months randomized controlled trial (CarNET: NCT02200068), patients with RA and internet access were randomized to: access without incentives to the Sanoia platform after minimal training, or usual care. The primary outcome was the change from baseline in patient-physician interactions, by the patient-reported Perceived Efficacy in Patient-Physician Interactions (PEPPI-5) questionnaire. The number of accesses to Sanoia was recorded and satisfaction with the platform was assessed through a 0-10 numeric rating scale. Analyses were in intention to treat (ITT), on SAS. RESULTS: Of 320 RA patients (159 Sanoia versus 161 usual care), mean (standard deviation) age was 57.0 (12.7) years, mean (SD) disease duration was 14.6 (11.1) years, 216 (67.5%) were taking a biologic and 253 (79.1%) were female. Mean (SD) PEPPI scores at baseline and 12 months were 38.6 (8.2) and 39.2 (8.0) (delta=+0.60 [5.52]) versus 39.7 (7.3) and 38.8 (8.0) (delta=-0.91 [6.08]) in the Sanoia and control group, respectively (P=0.01). Although mean satisfaction with the platform was very high (1.46 [1.52]), 41 patients (25.7%) never accessed Sanoia. CONCLUSION: Giving RA patients access to the interactive Sanoia e-health platform led to a small improvement in patient-perceived patient-physician interactions. A disjunction between patient satisfaction and access to the platform was noted. E-Health platforms are promising in RA.

EULAR recommendations for the management of rheumatoid arthritis with synthetic and biological disease-modifying antirheumatic drugs: 2016 update.

Recent insights in rheumatoid arthritis (RA) necessitated updating the European League Against Rheumatism (EULAR) RA management recommendations. A large international Task Force based decisions on evidence from 3 systematic literature reviews, developing 4 overarching principles and 12 recommendations (vs 3 and 14, respectively, in 2013). The recommendations address conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs) (methotrexate (MTX), leflunomide, sulfasalazine); glucocorticoids (GC); biological (b) DMARDs (tumour necrosis factor (TNF)-inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab), abatacept, rituximab, tocilizumab, clazakizumab, sarilumab and sirukumab and biosimilar (bs) DMARDs) and targeted synthetic (ts) DMARDs (Janus kinase (Jak) inhibitors tofacitinib, baricitinib). Monotherapy, combination therapy, treatment strategies (treat-to-target) and the targets of sustained clinical remission (as defined by the American College of Rheumatology-(ACR)-EULAR Boolean or index criteria) or low disease activity are discussed. Cost aspects were taken into consideration. As first strategy, the Task Force recommends MTX (rapid escalation to 25 mg/week) plus short-term GC, aiming at >50% improvement within 3 and target attainment within 6 months. If this fails stratification is recommended. Without unfavourable prognostic markers, switching to-or adding-another csDMARDs (plus short-term GC) is suggested. In the presence of unfavourable prognostic markers (autoantibodies, high disease activity, early erosions, failure of 2 csDMARDs), any bDMARD (current practice) or Jak-inhibitor should be added to the csDMARD. If this fails, any other bDMARD or tsDMARD is recommended. If a patient is in sustained remission, bDMARDs can be tapered. For each recommendation, levels of evidence and Task Force agreement are provided, both mostly very high. These recommendations intend informing rheumatologists, patients, national rheumatology societies, hospital officials, social security agencies and regulators about EULAR's most recent consensus on the management of RA, aimed at attaining best outcomes with current therapies.

Performance of patient-reported outcomes in the assessment of rheumatoid arthritis disease activity:the experience of the ESPOIR cohort.

OBJECTIVES: Rheumatoid arthritis (RA) activity can be assessed by several outcome measures. The importance of patient-reported outcomes (PROs) has recently been advocated. Our objective was to determine whether patient self-assessment can reflect RA disease activity. METHODS: Data from patients included in the early arthritis ESPOIR cohort and fulfilling 2010 ACR/EULAR criteria for RA at month 12 were used. Data for several PROs (visual analogue scale for fatigue, pain, patient assessment of disease activity; Health Assessment Questionnaire [HAQ]; Medical Outcomes Study Short Form 36 [SF36]; Echelle de Mesure de l'Impact de la polyarthrite Rhumatoïde-court [EMIR-court] and Routine Assessment of Patient Index Data 3 [RAPID3]) were collected and their association with disease activity measured by Disease Activity Score in 28 joints-3 variables (DAS28-3v) was assessed. The association of PROs and disease activity was assessed by explained variance, Pearson correlation and performance of each PRO in differentiating low versus high disease activity states. RESULTS: We evaluated data for 677 patients. Whatever the disease activity, less impaired PROs was associated with the lowest disease activity. All PROs were moderately correlated with RA disease activity. The RAPID3 had the best association with DAS28-3v in determining RA disease activity state (r=0.45-0.55, explained variance 30-45%, sensitivity 69-100% and specificity 55-78%). Global PROs (RAPID3, EMIR-court) had the highest association with disease activity, followed by PROs assessing physical function. CONCLUSIONS: The association of PROs and RA disease activity (DAS28-3v) remains moderate. RAPID3, a global PRO, had the best association with disease activity as compared with other analysed PROs.

Improvement in patient-reported outcomes after rituximab in rheumatoid arthritis patients: An open-label assessment of 175 patients.

OBJECTIVE: Patient-reported outcomes (PROs) reflect treatment efficacy from the patients' perspective. The objective was to assess PROs improvement with rituximab in rheumatoid arthritis. METHODS: Patients with long-standing rheumatoid arthritis received rituximab 1000mg twice at 2 weeks interval, and were assessed over 6 months. PROs including physical PROs (pain, functional assessment, physical quality of life) and mental or mixed aspects (fatigue, sleep and mental quality of life) were assessed. Standardized response means were calculated. Early improvement in PROs was used to predict EULAR response at 6 months. RESULTS: For the 175 patients (mean age 54.6±10.6 years, mean disease duration 12.9±9.3 years), the plateau of efficacy of rituximab on PROs was reached at week 12, and the effect was more prominent on physical PROs (e.g., pain standardized response means -0.75 [95% confidence interval -0.91; -0.60]), than on sleep (-0.43; [-0.56; -0.29]). It was not possible to accurately predict 6-month EULAR response by early improvement in PROs. CONCLUSION: Rituximab was effective on PROs with an early effect. PROs reflecting physical aspects were more modulated by this biologic than other PROs (fatigue, sleep or mental quality of life). Links between sleep difficulties, fatigue and RA should be further studied.

Repeated anticitrullinated protein antibody and rheumatoid factor assessment is not necessary in early arthritis: results from the ESPOIR cohort.

OBJECTIVE: Presence and levels of anticyclic citrullinated peptide antibodies (anti-CCP) and rheumatoid factor (RF) contribute to the classification and prognosis of rheumatoid arthritis (RA). The objective was to determine the usefulness of repeating anti-CCP/RF measurements during the first 2 years of followup in patients with early arthritis. METHODS: In patients with early undifferentiated arthritis, serial anti-CCP and RF were measured using automated second-generation assays every 6 months for 2 years. Frequencies of seroconversions (from negative to positive or the reverse) and changes in antibody levels during followup were determined. RESULTS: In all, 775 patients, mean (SD) age 48.2 (12.5) years, mean symptom duration 3.4 (1.7) months, 76.6% female, were analyzed; 614 (79.2%) satisfied the American College of Rheumatology/European League Against Rheumatism 2010 classification criteria for RA at baseline. At baseline, respectively for anti-CCP and RF, 318 (41.0%) and 181 (23.4%) patients were positive, of whom 298 (93.7% of the positive) and 111 (61.3% of the positive) were highly positive (above 3 × upper limit of the norm). There were only 12 anti-CCP seroconversions toward the positive (i.e., 2.6% of the anti-CCP-negative), 21 seroconversions toward the negative (6.6% of the anti-CCP-positive), and 8 (1.0%) changes to a higher anti-CCP level category during the 2-year followup; respectively for RF, 27 (4.6%), 95 (52.5%), and 13 (1.7%). CONCLUSION: In this cohort of patients with early arthritis, including in the subset of patients who did not fulfill the RA criteria, antibody status showed little increase over a 2-year period. Repeated measurements of anti-CCP/RF very infrequently offer significant additional information.

Defining erosive disease typical of RA in the light of the ACR/EULAR 2010 criteria for rheumatoid arthritis; results of the data driven phase.

BACKGROUND: According to the 2010 criteria, rheumatoid arthritis (RA) can be classified in the presence of ≥6 points on the criteria or 'typical' erosive disease. RA-specific erosiveness however has not been defined yet. This study reports the results of the data driven phase of a European League Against Rheumatism (EULAR) taskforce aiming to define RA-specific erosiveness. METHODS: Baseline radiographs of hands and feet of 980 Dutch and 811 French early arthritis patients were studied on the number and site of erosive joints. Test characteristics were determined, with the outcome measures being initiation of methotrexate (MTX) therapy or any disease modifying antirheumatic drug (DMARD) therapy within the first year of disease and arthritis persistency over 5 years. Analyses were repeated in the patients with <6 points on the American College of Rheumatology/EULAR 2010 criteria. RESULTS: In both cohorts comparable test characteristics were observed for the outcomes MTX therapy, any DMARD therapy and arthritis persistency. Test characteristics were not influenced by the site of erosiveness. The specificity observed was >50% for ≥1 erosive joint, >80% for ≥3 erosive joints and >90% for ≥5 erosive joints. When analysing the patients not fulfilling the 2010 criteria (n=308 and 149), specificity was >60% for ≥1 erosive joint, >90% for ≥3 erosive joints and >95% for ≥5 erosive joints. Few of these patients fulfilled the radiological criterion; 27-36 patients had ≥3 erosive joints and 13-14 patients had ≥5 erosive joints. CONCLUSIONS: RA-specific erosiveness can be defined with high specificity at several cut-offs for the number of erosive joints in two independent cohorts with multiple different outcomes. The final radiological criterion will be established in the next phase.

Nonsteroidal antiinflammatory drug intake according to the Assessment of SpondyloArthritis International Society Score in clinical trials evaluating tumor necrosis factor blockers: example of etanercept in advanced ankylosing spondylitis.

OBJECTIVE: To evaluate the interest of the Assessment of SpondyloArthritis international Society (ASAS) nonsteroidal antiinflammatory drug (NSAID) score as a quality indicator and a potential outcome measure in clinical studies. METHODS: We used data from patients with active, advanced, axial ankylosing spondylitis refractory to NSAIDs. The study design was a 12-week, randomized, placebo-controlled period followed by a 12-week open-label extension. The ASAS-NSAID score was collected during 3 periods of interest (i.e., the 12 weeks preceding baseline, the 12 weeks of the placebo-controlled trial, and the 12 weeks of the open-label trial). RESULTS: For the 82 enrolled patients, the mean ± SD ASAS-NSAID score at baseline was similar between the 2 groups: 93 ± 76 and 74 ± 54 in the etanercept and placebo groups, respectively. There was no significant change in the ASAS-NSAID score during the first part of the trial, as recommended by the protocol. There was a statistically significant decrease in the ASAS-NSAID score during the second part of the trial with a relevant effect size (-0.56) in the placebo to etanercept group. CONCLUSION: This study confirms the feasibility and simplicity of the ASAS-NSAID score and suggests that such a score be integrated in all studies in spondylarthritis either to check the quality of the observed data (i.e., intergroup baseline characteristics) or to evaluate the NSAID-sparing effect of other therapies.

Rheumatoid arthritis of the hand: monitoring with a simplified MR imaging scoring method--preliminary assessment.

PURPOSE: To assess a simplified scoring method (Simplified Rheumatoid Arthritis Magnetic Resonance Imaging Score [SAMIS]) developed to shorten interpretation time, while retaining both correlation with Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS) and same or better intra- and interreader reliability. MATERIALS AND METHODS: Ethics board approval and written patient consent were obtained. The study was HIPAA compliant. Thirty-eight patients with rheumatoid arthritis and 20 patients with no or early unclassified arthritis underwent magnetic resonance imaging of both wrists and hands. RAMRIS was used to evaluate erosions (scale, 0-10), edema (scale, 0-3), and synovitis (scale, 0-3). SAMIS assessed only one hand and was based on the radiographic Simple Erosion Narrowing Score, thus reducing the number of study areas from 116 to 36. Erosions were scored with a scale from 1 to 10. Edema and synovitis were, respectively, scored with scales from 0 to 1 and 0 to 2. SAMIS correlation with RAMRIS was tested by using the Spearman test. Last, the intra- and interobserver reproducibility of both scores were calculated. RESULTS: SAMIS was closely correlated with RAMRIS for the entire series (r = 0.91, 0.79, and 0.94, respectively, for erosion, edema, and synovitis), as well as in patients with rheumatoid arthritis (r = 0.93, 0.81, and 0.92) and those with no or unclassified arthritis (r = 0.83, 0.73, and 0.94). The time needed to assess examination results with RAMRIS ranged from 5 to 20 minutes (13 minutes +/- 3.90 [standard deviation]), whereas it ranged from 2 to 7 minutes (5 minutes +/- 1.45) with SAMIS. For each of the three features (erosion, edema, and synovitis), intraobserver agreement (RAMRIS: kappa = 0.67, 0.94, 0.81, respectively; SAMIS: kappa = 0.66, 1.0, 0.91) and interobserver agreement (RAMRIS: kappa = 0.61, 0.58, 0.74, respectively; SAMIS: kappa = 0.59, 0.81, 0.81) were good to excellent. CONCLUSION: This simplified reproducible scoring scheme could be used to monitor joint damage in rheumatoid arthritis. (c) RSNA, 2010.

EULAR recommendations for the management of rheumatoid arthritis with synthetic and biological disease-modifying antirheumatic drugs.

Treatment of rheumatoid arthritis (RA) may differ among rheumatologists and currently, clear and consensual international recommendations on RA treatment are not available. In this paper recommendations for the treatment of RA with synthetic and biological disease-modifying antirheumatic drugs (DMARDs) and glucocorticoids (GCs) that also account for strategic algorithms and deal with economic aspects, are described. The recommendations are based on evidence from five systematic literature reviews (SLRs) performed for synthetic DMARDs, biological DMARDs, GCs, treatment strategies and economic issues. The SLR-derived evidence was discussed and summarised as an expert opinion in the course of a Delphi-like process. Levels of evidence, strength of recommendations and levels of agreement were derived. Fifteen recommendations were developed covering an area from general aspects such as remission/low disease activity as treatment aim via the preference for methotrexate monotherapy with or without GCs vis-à-vis combination of synthetic DMARDs to the use of biological agents mainly in patients for whom synthetic DMARDs and tumour necrosis factor inhibitors had failed. Cost effectiveness of the treatments was additionally examined. These recommendations are intended to inform rheumatologists, patients and other stakeholders about a European consensus on the management of RA with DMARDs and GCs as well as strategies to reach optimal outcomes of RA, based on evidence and expert opinion.

Non-drug treatment (excluding surgery) in rheumatoid arthritis: clinical practice guidelines.

OBJECTIVES: Because drugs do not halt joint destruction in rheumatoid arthritis (RA), non-drug treatments are an important adjunct to drug treatment. Establishing rules governing their use is difficult because treatment is multidisciplinary, complex, and difficult to assess. The aims of these guidelines were to (a) establish the indications for physical therapies and for educational, psychological, and other non-drug interventions, (b) address social welfare, occupational, and organizational issues. METHODS: A systematic literature search (MEDLINE, EMBASE, CINAHL, Pascal, Cochrane Library, HTA database) (1985-2006) was completed with information obtained from specialty societies and the grey literature. A review of the studies meeting inclusion criteria, with evidence levels, was used by a multidisciplinary working group (18 experts) to draft guidelines. Consensus was reached when evidence was lacking on key topics. The draft guidelines were scored by 60 peer reviewers, amended when necessary, and then validated by the HAS Board. RESULTS: Of the 1819 articles retrieved, 817 were analysed and 382 cited in the report. Low-power randomized clinical trials constituted the highest level of evidence. Grade B guidelines (intermediate evidence level) concerned aerobic activities, dynamic muscular strengthening, and therapeutic patient education. Grade C (low evidence level) concerned use of rest orthoses or assistive devices, balneotherapy and spa therapy, self-exercise programmes, and conventional physiotherapy. Professional agreement (no scientific evidence) was reached for orthotic insoles and footwear, chiropody care, thermotherapy, acupuncture, psychological support, occupational adjustments, and referral to social workers. CONCLUSION: Aerobic activities, dynamic muscular reinforcement, and therapeutic patient education are valuable in non-drug management of RA.

Choice of second-line disease-modifying antirheumatic drugs after failure of methotrexate therapy for rheumatoid arthritis: a decision tree for clinical practice based on rheumatologists' preferences.

OBJECTIVE: To survey rheumatologists' preferences for the choice of a second-line disease-modifying antirheumatic drug (DMARD) after inadequate response with methotrexate (MTX) therapy in rheumatoid arthritis (RA). METHODS: Thirty-six rheumatologists stated their preferences for RA treatment after inadequate response with MTX therapy (optimal dose at least 6 months). From the initial scenario, we derived 54 vignettes varying by rheumatoid factor or anti-cyclic citrullinated peptide antibody presence, swollen joint count, Disease Activity Score in 28 joints, and structural damage. Respondents stated their preference among 5 therapeutic options: MTX continuation, switch to another conventional DMARD, addition of another conventional DMARD, addition of anakinra, or addition of a tumor necrosis factor (TNF) blocker. Presentation by pairs yielded 10 combinations of strategies for each variant, totaling 540 vignettes; participants evaluated a random sample of 180 vignettes. Determinants of each top-ranked option were analyzed by logistic regression. The compilation of these data served to define a therapeutic algorithm. RESULTS: The responses of 33 rheumatologists were analyzable. Therapeutic preferences corresponded to the top-ranked options. For patients with mild or moderately active RA, either a switch or step-up strategy to another conventional DMARD was top ranked. TNF blockers were preferred for RA patients with high disease activity or progressive structural damage. On the basis of these preferences, we developed a simple decision tree for use in daily clinical practice. CONCLUSION: Our simple, easy-to-use decision tree developed from rheumatologists' preferences for therapy after failure of MTX therapy in RA treatment may guide rheumatologists in daily practice to choose a second-line DMARD.

Health assessment questionnaire score is the best predictor of 5-year quality of life in early rheumatoid arthritis.

OBJECTIVE: To evaluate and determine prognostic factors of 5-year quality of life in patients with early rheumatoid arthritis (RA). METHODS: A cohort of 191 patients with RA and disease duration < 1 year was prospectively followed over 5 years. The outcome measure was quality of life as assessed by the Arthritis Impact Measurement Scales 2 (AIMS2). Univariate analysis, then stepwise multiple logistic regression, was used to find independent baseline prognostic variables. RESULTS: After accounting for death, loss of followup, and missing data, 158 patients (82.72%) were included in the analysis. The mean AIMS2 physical, symptom, psychological, social interaction, and work scores after 5 years were 1.6 (range 0-6.88), 4.0 (0-10), 3.48 (0-9.22), 4.06 (0-8.69), and 1.87 (0-8.13), respectively. The AIMS2 physical component was significantly correlated with Health Assessment Questionnaire (HAQ) score at 5 years. Logistic regression analysis revealed that the baseline values able to predict the 5-year physical, psychological, symptom, social interaction, and work status were, respectively: HAQ score and erythrocyte sedimentation rate (ESR), body mass index (BMI), HAQ; erosion score and sex, HAQ; ESR and anti-perinuclear antibody; matrix metalloproteinase-3 (MMP3) level, joint space narrowing, and tender joint scores; HAQ score and age. CONCLUSION: The multidimensional structure of the AIMS2 allowed us to assess the 5-year health-related quality of life in early RA. Using this instrument as an outcome variable, prognostic factors were selected and varied widely depending on the evaluated domain. The baseline HAQ score was the best predictive factor of 4 of the 5 domains of the AIMS2.

Predictive factors of 5-year health assessment questionnaire disability in early rheumatoid arthritis.

OBJECTIVE: To determine prognostic factors of disability in early rheumatoid arthritis (RA) and to investigate the radiological and functional course of the disease. METHODS: A total of 191 patients with early RA (diagnosed for less than one year) according to American College of Rheumatology criteria were followed prospectively for 5 years. At baseline and at endpoint, Stanford Health Assessment Questionnaire (HAQ) scores and radiological scores (Sharp's score modified by van der Heijde) were performed. Correlations between numerous baseline data and HAQ score at endpoint were analyzed, using nonparametric tests. A multilinear regression model was performed to select independent prognostic factors of HAQ disability. RESULTS: During the 5-year followup, mean HAQ decreased from 1.3 (+/- 0.7) to 0.6 (+/- 0.6). There were 98 (65.3%) patients with a score > 1 point at baseline, but only 46 (27.4%) after 3 years and 34 (21.8%) after 5 years. Moreover, 90% of the patients had an improvement of the disability score. Final HAQ disability was associated with baseline values of HAQ score, Pain, Ritchie index, tender joint count, Disease Activity Score, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and erosion. Multivariate analysis selected baseline HAQ score, Ritchie index, ESR, CRP, and presence of erosion as independent prognostic factors of HAQ disability. The probability cutoff in the logistic model was selected to minimize the sum of false positive and false negative values: negative predictive value = 92.71%, positive predictive value = 46.15%, p = 0.408. Sex, age, IgM and IgA rheumatoid factors, other tested autoantibodies, and HLA class II genes did not contribute significantly to prediction of the disability after 5 years. At baseline, mean scores were 3.6 units (+/- 7.7) for total radiological score, 1.7 (+/- 4.5) for erosion score, and 1.9 (+/- 3.7) for joint space narrowing score. After 5 years, they were 17.9 +/- 22.3, 6.9 +/- 9.5, and 11.0 +/- 15.4, respectively. No erosion was present at the start in 58.0% of patients, compared to 24.2% and 22.4% at 3 and 5 years. Global radiographic progression concerned 87 patients (55.8%) during the 5 years. CONCLUSION: During the first 5 years of RA, radiological damage increased progressively in half of the patients, whereas HAQ disability improved in most of them during the same period of time and could be predicted by baseline values of HAQ score, Ritchie index, ESR, CRP, and presence (or absence) of erosion.
