Influence of the timing of biological treatment initiation on Juvenile Idiopathic Arthritis long-term outcomes

BACKGROUND

Juvenile idiopathic arthritis (JIA) treatment is aimed at inducing remission to prevent joint destruction and disability. However, it is unclear what is the long-term impact on health-related outcomes of the timing of biological disease-modifying antirheumatic drug (bDMARD) initiation in JIA. Our aim was to evaluate the long-term impact of the time between JIA onset and the initiation of a bDMARD in achieving clinical remission, on physical disability and health-related quality of life (HRQoL).

METHODS

Adult JIA patients registered in the Rheumatic Diseases Portuguese Register (Reuma.pt) and ever treated with bDMARD were included. Data regarding socio-demographic, JIA-related characteristics, disease activity, physical disability (HAQ-DI), HRQoL (SF-36), and treatments were collected at the last visit. Patients were divided into 3 groups (≤ 2 years, 2-5 years, or > 5 years), according to the time from disease onset to bDMARD initiation. Regression models were obtained considering remission on/off medication, HAQ-DI, SF-36, and joint surgeries as outcomes and time from disease onset to bDMARD start as an independent variable.

RESULTS

Three hundred sixty-one adult JIA patients were evaluated, with a median disease duration of 20.3 years (IQR 12.1; 30.2). 40.4% had active disease, 35.1% were in remission on medication, and 24.4% were in drug-free remission; 71% reported some degree of physical disability. Starting a bDMARD > 5 years after disease onset decreased the chance of achieving remission off medication (OR 0.24; 95% CI 0.06, 0.92; p = 0.038). Patients who started a bDMARD after 5 years of disease onset had a higher HAQ and worse scores in the physical component, vitality, and social function domains of SF-36, and more joint surgeries when compared to an earlier start.

CONCLUSION

Later initiation of bDMARDs in JIA is associated with a greater physical disability, worse HRQoL, and lower chance of drug-free remission in adulthood.

The idiopathic inflammatory myopathies module of the Rheumatic Diseases Portuguese Register

AIMS

To characterise the idiopathic inflammatory myopathies (IIM) module of the Rheumatic Diseases Portuguese Register (Reuma.pt/myositis) and the patients in its cohort.

METHODS

Reuma.pt is a web-based system with standardised patient files gathered in a registry. This was a multicentre open cohort study, including patients registered in Reuma.pt/myositis up to January 2022.

RESULTS

Reuma.pt/myositis was designed to record all relevant data in clinical practice and includes disease-specific diagnosis and classification criteria, clinical manifestations, immunological data, and disease activity scores. Two hundred eighty patients were included, 71.4% female, 89.4% Caucasian, with a median age at diagnosis and disease duration of 48.9 (33.6-59.3) and 5.3 (3.0-9.8) years. Patients were classified as having definite (N=57/118, 48.3%), likely (N=23/118, 19.5%), or possible (N=2/118, 1.7%) IIM by 2017 EULAR/ACR criteria. The most common disease subtypes were dermatomyositis (DM, N=122/280, 43.6%), polymyositis (N=59/280, 21.1%), and myositis in overlap syndromes (N=41/280, 14.6%). The most common symptoms were proximal muscle weakness (N=180/215, 83.7%) and arthralgia (N=127/249, 52.9%), and the most common clinical signs were Gottron's sign (N=75/184, 40.8%) and heliotrope rash (N=101/252, 40.1%). Organ involvement included lung (N=78/230, 33.9%) and heart (N=11/229, 4.8%) involvements. Most patients expressed myositis-specific (MSA, N=158/242, 65.3%) or myositis-associated (MAA, 112/242, 46.3%) antibodies. The most frequent were anti-SSA/SSB (N=70/231, 30.3%), anti-Jo1 (N=56/236, 23.7%), and anti-Mi2 (N=31/212, 14.6%). Most patients had a myopathic pattern on electromyogram (N=101/138, 73.2%), muscle oedema in magnetic resonance (N=33/62, 53.2%), and high CK (N=154/200, 55.0%) and aldolase levels (N=74/135, 54.8%). Cancer was found in 11/127 patients (8.7%), most commonly breast cancer (N=3/11, 27.3%). Most patients with cancer-associated myositis had DM (N=8/11, 72.7%) and expressed MSA (N=6/11) and/or MAA (N=3/11). The most used drugs were glucocorticoids (N=201/280, 71.8%), methotrexate (N=117/280, 41.8%), hydroxychloroquine (N=87/280, 31.1%), azathioprine (N=85/280, 30.4%), and mycophenolate mofetil (N=56/280, 20.0%). At the last follow-up, there was a median MMT8 of 150 (142-150), modified DAS skin of 0 (0-1), global VAS of 10 (0-50) mm, and HAQ of 0.125 (0.000-1.125).

CONCLUSIONS

Reuma.pt/myositis adequately captures the main features of inflammatory myopathies' patients, depicting, in this first report, a heterogeneous population with frequent muscle, joint, skin, and lung involvements.

Effectiveness of biosimilar infliximab CT-P13 compared to originator infliximab in biological-naïve patients with rheumatoid arthritis and axial spondyloarthritis: data from the Portuguese Register

OBJECTIVES

To compare the effectiveness of the infliximab biosimilar CT-P13 with originator infliximab over 24 months of follow-up in biological-naïve patients with rheumatoid arthritis (RA) and axial spondyloarthritis (axSpA).

METHODS

Biological-naïve patients from the Rheumatic Diseases Portuguese Register (Reuma.pt), with a clinical diagnosis of RA or axSpA, who were starting either the infliximab biosimilar CT-P13 or the originator infliximab after 2014 (date of market entry of CT-P13 in Portugal), were included. Patients on biosimilar and originator were compared regarding different response outcomes at 3 and 6 months, adjusting for age, sex and baseline C-reactive protein (CRP). The main outcome was the change in DAS28-erytrocyte sedimentation rate (ESR) for RA and the ASDAS-CRP for axSpA. Additionally, the effect of infliximab biosimilar vs originator on different response outcomes over 24 months of follow-up was tested with longitudinal generalized estimating equations (GEE) models.

RESULTS

In total, 140 patients were included, 66 (47%) of which with RA. The distribution of patients starting the infliximab biosimilar and the originator was the same between the two diseases (approximately 60% and 40%, respectively). From the 66 patients with RA, 82% were females, mean age was 56 years (SD 11) and mean DAS28-ESR 4.9 (1.3) at baseline. As for the patients with axSpA, 53% were males, mean age was 46 years (13) and mean ASDAS-CRP 3.7 (0.9) at baseline. There were no differences in efficacy between RA patients treated with the infliximab biosimilar and the originator, either at 3 months (∆DAS28-ESR: -0.6 (95% CI -1.3; 0.1) vs -1.2 (-2.0; -0.4)), or at 6 months (∆DAS28-ESR: -0.7 (-1.5; 0.0) vs -1.5 (-2.4; -0.7)). This was also true for patients with axSpA (∆ASDAS-CRP at 3 months: -1.6 (-2.0; -1.1) vs -1.4 (-1.8; -0.9) and at 6 months: -1.5 (-2.0; -1.1) vs -1.1 (-1.5; -0.7)). Results were similar with the longitudinal models over 24 months.

CONCLUSION

There are no differences in effectiveness between the infliximab biosimilar CT-P13 and the infliximab originator in the treatment of biological-naïve patients with active RA and axSpA in clinical practice.

Predictors of cardiac involvement in idiopathic inflammatory myopathies

Objectives

Idiopathic inflammatory myopathies (IIM) are a group of rare disorders that can affect the heart. This work aimed to find predictors of cardiac involvement in IIM.

Methods

Multicenter, open cohort study, including patients registered in the IIM module of the Rheumatic Diseases Portuguese Register (Reuma.pt/Myositis) until January 2022. Patients without cardiac involvement information were excluded. Myo(peri)carditis, dilated cardiomyopathy, conduction abnormalities, and/or premature coronary artery disease were considered.

Results

230 patients were included, 163 (70.9%) of whom were females. Thirteen patients (5.7%) had cardiac involvement. Compared with IIM patients without cardiac involvement, these patients had a lower bilateral manual muscle testing score (MMT) at the peak of muscle weakness [108.0 ± 55.0 vs 147.5 ± 22.0, p=0.008] and more frequently had oesophageal [6/12 (50.0%) vs 33/207 (15.9%), p=0.009] and lung [10/13 (76.9%) vs 68/216 (31.5%), p=0.001] involvements. Anti-SRP antibodies were more commonly identified in patients with cardiac involvement [3/11 (27.3%) vs 9/174 (5.2%), p=0.026]. In the multivariate analysis, positivity for anti-SRP antibodies (OR 104.3, 95% CI: 2.5-4277.8, p=0.014) was a predictor of cardiac involvement, regardless of sex, ethnicity, age at diagnosis, and lung involvement. Sensitivity analysis confirmed these results.

Conclusion

Anti-SRP antibodies were predictors of cardiac involvement in our cohort of IIM patients, irrespective of demographical characteristics and lung involvement. We suggest considering frequent screening for heart involvement in anti-SRP-positive IIM patients.

AB1357 THE BEST CUT-OFF POINT FOR MEDIAN NERVE CROSS SECTIONAL AREA AT THE LEVEL OF PISIFORM BONE

Background

Carpal tunnel syndrome (CTS) is a focal neuropathy caused by compression of the median nerve (MN) at the wrist. Electromyography (EMG) is the gold standard for the diagnosis of CTS. Currently, the ultrasound (US) is frequently used as an initial screening exam by measuring the cross-sectional area (CSA) of the MN. The cut-off point of the CSA at the pisiform bone level to define CTS remains controversial with previous studies reporting values between 6.5mm2 and 15mm2 (1).

Objectives

The aim of this study is to determine the best cut-off point of the CSA for the diagnosis of CTS.

Methods

Cross-sectional study at a Tertiary Rheumatology Department including patients aged ≥ 18 years with symptoms compatible with CTS. Sociodemographic and clinical data, visual analogue scale for pain (VAS), Boston Questionnaire (BQ), and the results of EMG and US performed in each patient were collected. The EMG was performed according to the standardized protocol (sensory conduction velocity, sensory amplitude, distal sensory and motor latency), and the patients were categorized in 4 groups: normal, mild, moderate, and severe. A rheumatologist with expertise in imaging performed all the US evaluations by means of a 6–18-MHz (Siemens ACUSON S 2000) linear array transducer. The largest CSA of the MN was measured at the level of the pisiform bone. Receiver operating characteristic (ROC) curve was used to determine optimal cut-off values of the CSA taking the EMG result as the gold-standard. One-way ANOVA test was used to compare CSA between the 4 EMG groups.

Results

Fifty patients were included, 90% were female, mean age was 52.1 ± 10.8 years and median duration of symptoms was 28.0 (IQR 23.0-31.0) months. The mean VAS was 4.2 ± 2.9. In the BQ there was a mean symptom severity score of 2.4 ± 0.6 and a mean functional status score of 2.0 ± 0.9. One-way ANOVA showed that mean CSA values were significantly different in the 4 groups of patients. The Ryan-Einot-Gabriel-Welsch post hoc analysis showed that only the mean CSA of patients with severe STC is different from the remaining groups defined by EMG results. The best cut-off point for CSA at the pisiforme bone level for CTS diagnosis was 6.6 mm2 with a sensitivity and specificity of 92.9% and 75.0% (AUC=0.9, P<0.001). The positive and negative predictive values were 95.1% and 66.7%, respectively. For severe CTS diagnosis the best cut-off point for CSA was 12.3mm2 with a sensitivity of 82.4% and a specificity of 72.7% (AUC=0.8, P<0.001). The positive and negative predictive values were 60.9% and 88.9%, respectively.

Conclusion

In our study we found that the best cut-off point of the CSA was 6.6mm2 for distinguishing patients with/without CTS based on EMG alterations, with a high sensitivity and moderate specificity. This is a lower cut-off value than usually used in clinical practice and could be explained by small sample and the greater number of patients with mild and moderate STC on EMG.

POS0496 YOUNG VERSUS LATE-ONSET RHEUMATOID ARTHRITIS: A PROSPECTIVE 12 MONTH-FOLLOW-UP COHORT STUDY IN AN EARLY ARTHRITIS COHORT

Background:

Rheumatoid Arthritis (RA) is a chronic inflammatory arthropathy that can present at any age. Data regarding differences in the clinical course and outcome in Late-Onset Rheumatoid Arthritis (LORA) comparing to Young-Onset RA (YORA) are conflicting. Some studies suggested that LORA may represent a more benign form of RA (1), while others have shown a poorer prognosis in these patients (2,3). Only a few publications have included patients with early disease (3).

Objectives:

To compare demographic and clinical features between LORA and YORA patients, and clinical activity at baseline and after 12 months of initial therapy, in patients with early disease.

Methods:

We conducted a prospective cohort study of 12 months of follow-up based on an early arthritis clinic. Consecutive patients with early RA – less than 12 months duration – fulfilling ACR/EULAR 2010 and/or ACR 1987 RA classification criteria, were included and classified in LORA (disease onset ≥60 years) and YORA groups. Variables were collected from patients’ registries at first appointment after symptoms onset and after 12 months of treatment, according to a treat-to-target strategy. Independent t-test and chi-square test were performed to compare variables between groups.

Results:

We included 72 patients (40 (55.6%) YORA; 32 (44.4%) LORA), mean age at diagnosis 44.9±1.78 and 72.5± 1.34 years, respectively. In LORA group, the symptoms duration at first observation was shorter (17.0±2.26 vs. 23.8±2.45 weeks; p=0.046) and rheumatoid factor (RF)/ anti-citrullinated protein antibodies (ACPA) positivity was lower (28.1% vs 65.0%; p= 0.002; 31.3% vs 72.5%; p<0.001). At baseline, LORA had higher mean number of tender joints (9.76±1.29 vs 6.50±0.67; p=0.021), erythrocyte sedimentation rate (ESR) (45.7±4.98 vs. 29.3±3.74; p=0.011), C-reactive protein (CRP) (4.63±0.91 vs 2.22±0.46; p=0.022) and disease activity using DAS28-3V (5.11±0.28 vs 4.42±0.19; p=0.046), CDAI (33.7±3.39 vs 23.6±2.18; p=0.015) and SDAI (37.4±3.43 vs 26.3±2.57; p=0.015). At the end of follow-up, there were no statistically significant differences between LORA and YORA groups regarding treatment, disease activity and patient-reported outcomes at 12 months (Table 1).

AB0147 OLDER AGE AT ONSET AND NOT DISEASE ACTIVITY IS ASSOCIATED WITH FUNCTIONAL DISABILITY AT RA DIAGNOSIS: RESULTS FROM AN EARLY ARTHRITIS COHORT

Background:

Rheumatoid Arthritis (RA) is a chronic inflammatory arthropathy that potentially leads to loss of function and disability early in the disease course. (1) Optimizing physical function is one of the primary goals of RA treatment (2). Several demographic, psychosocial and clinical factors may influence the impact of RA upon physical capacity, and understanding their relative contribution to disability at disease diagnosis is key to an effective treatment approach.

Objectives:

To evaluate functional disability at the time of disease diagnosis and identify its demographic and clinical correlates in an early RA cohort.

Methods:

We conducted a cross-sectional study based on a Rheumatology centre early arthritis cohort. Consecutive patients with early RA – less than 12 months duration– fulfilling ACR/EULAR 2010 and/or ACR 1987 RA classification criteria, were included. Variables were collected from patients’ registries at the first rheumatology appointment after symptom’s onset. Functional disability was assessed using the Health Assessment Questionnaire- Disability Index (HAQ-DI) (range 0 to 3, higher values indicating greater disability). Independent t-test, one way-ANOVA and Pearson’s correlation coefficient were performed to evaluate differences between groups. Variables with p<0.1 were included in a stepwise multiple linear regression analysis to assess the independent association of variables with the HAQ-DI at baseline.

Results:

We included 71 patients (63.4% female, mean age 57.2 ±2.01 years). Mean HAQ-DI score was 1.42±0.08. Sociodemographic and clinical variables are described in Table 1. There was a significant difference in HAQ-DI scores between rheumatoid factor (RF) positive (mean 1.24±0.11) and RF negative (1.61±0.113) patients. HAQ-DI was positively weakly correlated with age (r=0.48; p<0.001), CDAI (r=0.43; p=0.038), SDAI (r=0.49; p=0.015), and moderately with DAS28-3V (r=0.60; p<0.001) and DAS28-3V-CRP (r=0.60; p<0.001). The number of tender (r=0.35; p=0.024) and swollen joints (r=0.42; p= 0.005), ESR (r=0.46; p=0.001), CRP (r=0.35; p=0.018), HADS-depression (r=0.46; p=0.023) and educational level (r= -0.48; p=0.002) were also associated with HAQ-DI in univariate analyses. After multivariate regression analysis, age at disease diagnosis (β= 0.022 [95 CI 0.010 to 0.034]; p= 0.001) was the only independent predictor of HAQ-DI (R2= 0.46, p=0.001).

Conclusion:

Older age at disease onset is associated with greater functional impairment at diagnosis, assessed by HAQ-DI, in this cohort of early RA patients, irrespective of disease activity and other clinical variables. This result suggests that older newly diagnosed RA patients may deserve special attention regarding physical function.

Early recognition of patients with arthritis is a crucial opportunity for optimal outcome. The Early Arthritis Clinic (EAC) of our department was created in 2012 to ensure a prompt access of these patients to efficient medical care. Patients may be referred based on a set of clinical criteria with less than 12 months duration and laboratory parameters: arthritis, inflammatory arthralgias, squeeze test, morning stiffness > 30 minutes, rheumatoid factor (RF), erythrocyte sedimentation rate (ESR)>30mm/h and C-reactive-protein>0.5mg/dL (CRP).

Objectives:

To assess the level of agreement between the referring physician and the rheumatologist, regarding the presence of each of the six referral criteria and to identify predictors of inflammatory arthritis.

Methods:

Cross sectional study including patients aged ≥ 18-year-old observed in the EAC between January 2012 and October 2019. Subjects who were referred to the EAC by a rheumatologist and those without available referral letter/medical records from the first visit to the EAC were excluded. Demographic data, provenience, referral criteria (presence/absence) and the final diagnosis [presence or not of an inflammatory rheumatic disease (IRD)] were collected from medical records. For the six referral criteria, the agreement between the referring physician and the rheumatologist was assessed using the Cohen’s Kappa. The presence of each referral criteria was compared between patients with and without an IRD using χ2 tests. Variables with p<0.1 or clinically relevant were included in forward stepwise multivariable logistic regression analysis to identify possible predictors for IRD. The statistical analysis was performed using SPSS® v21 andp<0.05 was considered statistically significant.

Results:

376 patients (70% female; mean age (±SD) 56.3±16.2 years) were included. Most patients were referred from primary care (84%); the remaining 16% include those referred from emergency department and other hospital specialties. We diagnosed an inflammatory arthritis in 62% (n = 232) of the patients. Table 1 shows the level of agreement between the referring physician and the rheumatologist, regarding the presence of the referral criteria.

In univariable analysis (IRD Vs non-IRD), inflammatory arthralgias (74% Vs 93%, p=0.01), squeeze test (24% Vs 55%, p=0.01), morning stiffness (49% Vs 63%, p=0.05), ESR (63% Vs 46%, p=0.01), CRP (62% Vs 48%, p=0.04) were associated to IRD. In multivariable analysis, only ESR (OR 5.0 [95% CI 1.9-13.0], p < 0.05) and inflammatory arthralgias (OR 0.15 [95% CI 0.04-0.52], p < 0.05) remained as predictors of IRD.

Conclusion:

Agreement between the referring physicians and the rheumatologist regarding then presence/absence of the referral criteria was poor in all clinical criteria and fair in laboratory criteria. Elevated ESR was an independent predictor of IRD and the description of inflammatory arthralgias was negatively correlated with IRD. These findings suggest the need to clarify the referral criteria used and to improve education among the physicians referring patients to the EAC.

AB0223 PHYSICIAN’S GLOBAL ASSESSMENT OF DISEASE ACTIVITY IN RHEUMATOID ARTHRITIS IS A RELIABLE AND RESPONSIVE TOOL IN CLINICAL practice

Background:

Physician’s global assessment of disease activity (PhGA) is highly influential upon treatment decisions taken by rheumatologists, surpassing the impact of DAS28. [1, 2]. However, data regarding its psychometric properties are scarce.

Objectives:

To evaluate the reliability and responsiveness of PhGA.

Methods:

We included two consecutive visits of RA patients followed in a Tertiary Rheumatology Department. Socio-demographic (age and gender) and clinical data were collected including tender (TJ28) and swollen (SJC28) joints in 28 count, C-Reactive Protein (CRP), Erythrocyte Sedimentation Rate (ESR), Disease activity Score (DAS28-3v-CRP, DAS28-3v-ESR, DAS28-4v-CRP, DAS28-4v-ESR), PhGA and Patient Global Assessment of disease Activity (PGA) through a Visual Analogic Scale (VAS) 0-100mm. Changes (Δ) between the two visits were calculated. Only patients without missing data were included. Correlations between ΔPhGA and change of other variables were assessed using Pearson’s correlations. Reliability was evaluated through Intraclass Correlation Coefficient (ICC) between two consecutive appointments in a subgroup of patients with stable disease activity (Δ DAS28-4vESR [-0.6 to 0.6]. An ICC above 0.8 was considered indicative of excellent reliability. Sensitivity to change was assessed in the subgroup of patients who improved their disease activity at least 0.6 on DAS28-4V-ESR, through Standardized Response Mean (SRM). The respective intervals of confidence were obtained through bootstrapping procedures. SRM above 0.8 were considered large. Independent factors associated with ΔPhGA were identified through multivariate linear regression analysis. p<0.05 was considered statistically significant

Results:

121 RA patients (84.3% female and 64.0±12.6 years) were included. Δ PhGA was weakly correlated with ΔCRP (r=0.23), Δ PGA (r=0.31) and Δ pain (r=0.37). Moderate to strong correlations were observed with Δ DAS28-3V-ESR (r=0.55), Δ SJC28 (r=0.56), Δ DAS28-3V-CRP (r=0.58), Δ DAS28-3V-CRP (r=0.60), Δ TJ28 (r=0.62) and Δ DAS28-4V-CRP (r=0.63). ICC between two consecutive visits was 0.7, [95%CI:0.47-0.83] and SRM was -1.01 [95%CI:-1.26-(-0.73)]. In the multivariate regression analysis, ΔSJC28 (β=4.01; 95% CI:3.07 to 4.96) and Δ Pain (β=0.18; 95%CI: 0.07 to 0.28) remained as independent factors associated with ΔPhGA (R2:0.49, p<0.01)

Conclusion:

In this study, PhGA showed a high reliability and sensitivity to change regarding disease activity, in clinical practice. Changes in SJC had the strongest association with change in PhGA scoring, but Δ Pain was also significantly correlated (graph 1).

AB0218 FUNCTIONAL DISABILITY AND PAIN BUT NOT DISEASE ACTIVITY ARE ASSOCIATED WITH POOR HEALTH-RELATED QUALITY OF LIFE IN A COHORT OF RHEUMATOID ARTHRITIS PATIENTS

Background:

Rheumatoid Arthritis (RA) is a systemic autoimmune disease that presents with joint pain and inflammation leading to significant disability and poor health-related quality of life (HRQoL) (1,2). Optimizing long-term HRQoL is the primary goal of disease management in RA (3).

Objectives:

To evaluate HRQoL and identify its influencing clinical and demographic factors in a Portuguese RA population.

Methods:

This is a cross-sectional study including consecutive patients fulfilling the ACR/EULAR 2010 and/or ACR 1987 RA classification criteria, followed at a tertiary Rheumatology Department. Sociodemographic and clinical variables were collected. HRQoL was assessed using the EuroQoL 5-Dimensional Descriptive System (EQ-5D) total score (normal range from -0.496 to 1.000, lower values indicating poorer HRQoL). Independent t-test and Pearson’s correlation coefficient were performed to evaluate EQ-5D differences between groups and examine its relationships with continuous variables, respectively. Variables with p<0.1 in univariate analysis were included in a stepwise multiple linear regression analysis to evaluate the independent association of variables with the EQ-5D score.

Results:

358 RA patients were included (80.20% female, mean age ± SD: 63.22 ± 0.66 years old). Mean EQ5D total score ±SD was 0.48 ± 0.01. Based on EQ-5D domains, 0.60% reported extreme problems with mobility, 3.40% extreme problems with self-care, 2.50% extreme problems with usual activities, 12.0% extreme pain or discomfort, and 7.30% extreme anxiety or depression symptoms (Fig. 1). There was a significant difference in EQ-5D scores between male (M=0.55, SD=0.24) and female gender (M=0.46, SD= 0.27); t (356) = -2.41, p=0.016. EQ-5D was weakly correlated with DAS-28-CRP (r=-0.32; p<0.001), moderately correlated with patient’s global assessment of disease activity (r=-0.54; p<0.001) and pain-visual analogue scale (pain-VAS) scores (r=-0.58; p<0.001) and strongly with Health Assessment Questionnaire (HAQ) score (r=-0.72; p< 0.001). After multivariate analysis, HAQ-score (β=-0.57 [95% CI -0.24 to -0.17]; p<0.001) and pain-VAS ((β=-0.25 [95% CI -0.003 to -0.002]; p<0.001) remained as independent predictors of EQ-5D (R2=0.56, p<0.001).

Conclusion:

Greater functional impairment and pain are associated with poor HRQoL in RA patients, and thus special attention must be given to treatment strategies providing the best patient-centred outcomes.

AB0179 BEYOND DISEASE ACTIVITY, PAIN, “TIME” AND “TIMING” ACCOUNT FOR DISABILITY IN PATIENTS WITH RHEUMATOID ARTHRITIS: RESULTS FROM A REAL-LIFE COHORT

Background:

Patients with rheumatoid arthritis (RA) suffer from joint pain, stiffness and fatigue and are therefore limited in their physical activities. Since functional disability is a major determinant of quality of life in patients with RA, an optimized approach should focus on the maintenance of functional ability.

Objectives:

To evaluate self-reported disability in RA patients and to identify its influencing clinical and demographic factors in a real-life cohort of patients with RA.

Methods:

Cross-sectional study of consecutive patients with RA fulfilling the ACR/EULAR 2010 and/or ACR 1987 RA classification criteria, followed in a Portuguese tertiary care centre. Variables collected included socio-demographic and clinical variables (disease duration; time from symptoms onset to diagnosis, classified as short (≤ 2 years) and long (> 2 years); time of diagnosis, categorised as <2000, 2000-2009, ≥2010); DAS28-CRP-3V and its individual components; pain assessed through visual analogue scale (0-100 mm) and self-perception of anxiety/ depression through EQ5D dimension 5. Disability was assessed through Health Assessment Questionnaire (HAQ) score and categorised as none-to-mild (<1) or moderate-to-severe (1-3). Comparison between groups was assessed through chi-square or T-student test, as adequate. Variables with p<0.1 and others clinically relevant in the researcher’s perspective were included in a multivariable logistic regression model. Previously to the analysis, all the assumptions were verified. Given the implementation of new strategies regarding diagnosis and treatment of RA in the last decade, a subgroup analysis was performed for patients with diagnosis performed after 2010).

Results:

A total of 251 patients were included (78.9% female, aged 62.0±12.1 years, disease duration 16.7±11.2 years), with a mean DAS28-CRP-3V of 2.24 ±0.87, with 65.3% being in remission or low disease activity. The mean HAQ score was 1.2±0.8. Over half of the patients (56.2%) reported moderate-to-severe disability. In the univariate analysis, moderate-to-severe disability was more frequent in female patients (60.6% vs 39.6%, p<0,006), in patients with moderate-to-severe self-perception of anxiety/depressive symptoms (67.2% vs 44.2%, p<0.001) and in patients with diagnosis before the year 2000, 2000-2009 than ≥2010 (71.4% vs 63.1% vs 36.7%; p< 0.001). In addition, patients with moderate-to-severe disability tended to be older (65.05 vs 57.98, p<0,001), to have longer disease duration (20.07 vs 12.39, p <0.001), to report more pain (VAS 58.08 vs 28.62, p<0.001) and to have higher disease activity (2.48 vs 1.95, p=0.001). In the multivariable analysis, pain (OR=1.04; 95%CI 1.03-1.06, p<0.001), disease activity (OR=1.51; 95%CI 1.01-2.26, p=0.049), and time of diagnosis (OR=0.553, 95%CI 0.38 -0.81, p=0.002) remained as independent factors associated with moderate-to-severe disability (R2: 0.40, p<0,001). In the subgroup of patients diagnosed after 2010, a longer time to diagnosis (>2 years) (OR=7.97, 95%CI 1.88-34.06; p=0.005) and pain (OR=1.05, 95%CI 1.03-1.08; p<0,001) remained as independent factors (R2= 0.44, p=<0.001).

Conclusion:

Functional disability remains a major problem in our patients with RA, despite clinical remission. Beyond non-modifiable factors, disease activity and pain are associated with higher disability. Moreover, in the subgroup of patients diagnosed after 2010 a long time to diagnosis was the major predictor of disability. However, a large variance of the reported functional disability remains unexplained. Hence, other factors should be properly evaluated in our patients in order to achieve a more holistic approach aiming at reducing functional disability.

AB0749 COMPARING PATIENT-PHYSICIAN DISCORDANCE IN RA AND PsA PATIENTS

Background:

Patient global Assessment (PGA) of disease activity is considered a key patient reported outcome in Rheumatoid Arthritis (RA) and Psoriatic Arthritis (PsA), both being included in combined indices of disease activity. However, patients and physicians frequently disagree in their assessment.

Objectives:

This study aimed at comparing the degree of this discrepancy and its determinants in RA and PsA.

Methods:

Cross sectional study including 100 patients with RA (ACR/EULAR 2010 criteria) and 100 patients with PsA with predominant peripheral joint involvement (CASPAR criteria), aged ≥18 years, randomly selected from the electronic registry Reuma.pt. Data were collected from the most recent rheumatology visit during the last year: sociodemographic data, disease duration (years), tender and swollen joint counts 0-28 (TJC and SJC), disease activity (DAS28 3V-PCR), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), patient’s pain assessment, PGA and physician global assessment (PhGA). The discrepancy between patients and physicians (ΔPPhGA) was defined as PGA minus PhGA, and a difference > |20mm| was taken as “discordance”. Categorical variables are presented as proportions and continuous variables as mean (±SD). Patient and clinical characteristics were compared between patients with RA and PsA using t- test and χ2 test, as adequate. Variables with p<0.05 or clinically relevant were included in multivariable logistic regression analysis to identify correlates for ΔPPhGA in the whole sample. A p≤0.05 was considered statistically significant.

Results:

Compared to PsA, patients with RA were more often female (90% Vs 49%,p< 0.05), older (66.7 ± 10.7 Vs 58.3 ± 12.2 years,p< 0.05) and had a shorter disease duration (18.2 ± 9.8 Vs 19.9 ± 9.7 years,p= 0.202). Regarding disease activity, the RA and PsA groups were comparable: DAS28 3V-PCR (2.3 ± 0.9 Vs 2.4 ± 1.0,p= 0.34). Patients with RA had a higher mean ΔPPhGA (30.4 ± 30.6 Vs 25.4 ± 27.5,p< 0.05), and were more frequently discordant to the physician (69% Vs 51%,p< 0.05). In univariable analysis, having RA, higher patient’s pain assessment and higher ESR were associated to patient-physician discordance. In multivariable analysis, only patient’s pain assessment (OR 1.04 [95% CI 1.03-1.06], p = 0.00) and TJC (OR 0.82 [95% CI 0.68-0.97], p = 0.02) remained as predictors of discordance.

Conclusion:

Despite comparable disease activity scores in RA and PsA patients, RA patients tend to have a worst self-perception of their disease activity compared to their physician´s. Patient’s pain assessment and TJC were the only predictors of patient-physician discordance, irrespective of the disease.

THU0111 PHYSICIAN’S GLOBAL ASSESSMENT OF DISEASE ACTIVITY IN RHEUMATOID ARTHRITIS: WHAT DO WE REALLY MEAN?

Background:

Physician’s global assessment of disease activity (PhGA) is included in some scores of disease activity and, demonstrably, plays a major role upon treatment decisions in rheumatoid arthritis (RA) [1, 2, 3]. Therefore, understanding the reasons underlying the physician´s assessment is crucial.

Objectives:

To understand the reasons underlying the physician´s assessment.

Methods:

Cross-sectional study, including consecutive RA patients followed in a Tertiary Rheumatology Department. Socio-demographic (age and gender) and clinical data were collected through a standardized protocol, including 28 tender (TJ28) and swollen (SJC28) joints count, C-Reactive Protein (CRP), Erythrocyte Sedimentation Rate (ESR), Disease activity Score (DAS28-4v-CRP and DAS28-4v-ESR), PhGA and Patient Global Assessment of disease Activity (PGA) through a Visual Analogic Scale (VAS) 0-100mm, Health Assessment Questionnaire (HAQ), European Quality of Life-5 Dimensions (EQ-5D) and Hospital Anxiety and Depression Scale (HADS). Correlation between PhGA and other continuous variables was evaluated through Pearson´s Correlation Coefficient and variables with p<0.05 in univariate analysis were included in multivariable linear regression (stepwise model).

Results:

392 RA patients (80.6% female, 65.3±12.6 years) were included. PhGA was weakly correlated with CRP (r=0.23), TJC28 (r=0.35), PGA (r=0.26), HAQ (r=0.31) and EQ5D (r=-0.21). Moderate correlations were observed with SJC28 (r=0.45) and DAS-4V-CRP (r=0.48). In multivariable analysis, SJC28 (β=4.14, 95%CI:3.16-5.12), CRP (β=0.22; 95%CI: 0.02-0.03), HAQ (β=4.46, 95%CI:1.50-7.42) and PGA (β=0.08; 95%CI:0.00-0.16) remained as independent correlates of PhGA (R2=0.27, p<0,05).

Conclusion:

In this study, PhGA was associated with SJC28, CRP, HAQ and PGA, suggesting that physicians adopt a comprehensive reading of the disease into account. However, a large proportion of the variance of PhGA remains unexplained. Given its driving role in treatment decisions, the need to standardize and better understand PhGA seems to deserve a closer attention.

FRI0229 THE IMPACT OF SYSTEMIC SCLEROSIS ON BODY IMAGE PATIENTS

Background:

Satisfaction with body image has a major impact in quality of life. Systemic sclerosis (SSc) is a can result in disfiguring physical changes.

Objectives:

Our aim was to determine the impact of systemic sclerosis on body image using the Satisfaction with Appearance Scale (SWAP). (1)

Methods:

Cross-sectional study including patients satisfying the 2013 American College of Rheumatology criteria for SSc diagnosis, aged ≥ 18 years, treated in a tertiary Rheumatology Department. Demographic and clinical data were collected from Reuma.pt and clinical records. All patients provided informed consent and fulfilled SWAP questionnaire, which consists of 14 questions in 4 subscales: satisfaction with facial appearance, satisfaction with non-facial appearance, social discomfort due to appearance and perceived social impact of appearance. Patients rate each item on a numerical rating scale from 1 (strongly disagree) to 7 (strongly agree). Scores for the facial and non-facial appearance range from 0-24 and scores for the social discomfort and perceived social impact subscales range from 0-18. Total SWAP score can range from 0-84 and higher values indicate greater dissatisfaction with appearance and poorer body image. A descriptive analysis was used to summarize demographic and clinical data; categorical variables were described using frequencies; and continuous data using mean and standard deviation. Correlation between variables [Rodnan, age, disease duration, Hospital Anxiety and Depression Scale (HADS) and Short Form Health Survey (SF36)] and SWAP score was tested with Pearson or Spearman coefficient, as appropriated. Scores of SWAP and its subscales in preclinical, limited and diffuse forms of SSc were compared using ANOVA test. Analyses were performed with SPSS Statistics, V.21 andp<0.05 was considered statistically significant.

Results:

We enrolled 38 patients, 84.2% (n=32) female, with mean age 60.3±14.5 years and mean disease duration 13.3±6.5 years. All but one were caucasian. Fifty percent (n=19) had a limited form, 26.3% (n=10) had preclinical scleroderma and 23.7% (n=9) had a diffuse form of SSc. Regarding the autoantibody profile: 63.2% (n=24) had anti-centromere antibodies, 28.9% (n=11) had anti-Scl-70 antibodies, 5.3% (n=2) had anti-PM antibodies and 2.6% (n=1) had no positive antibodies. The median of Rodnan scores was 4 (IQR 0-9). The total mean SWAP score was 44.8±12.5 with worse results at “Satisfaction with facial appearance” subscale (mean score 14.4±6.1). There is no statistically significant difference in the SWAP score (or its subscales) between the three diagnosis subtypes. No statistically significant correlation was found between the total and subscale SWAP scores and any of the continuous variables considered and no statistically significant difference was found between the different forms of SSc.

Conclusion:

We found no significant differences between preclinical, limited or diffused SS. SWAP scores were not significantly correlated with the total Rodnan score, age or disease duration. Contrary to our expectations SWAP did not show any relationship with depression, anxiety (HADS) or quality of Life (SF-36) However, our sample is too small to support definite conclusions. Further studies assessing body image in SSc and its impact in quality of life are warranted to support the holistic care of these patients.

SAT0029 PATIENT-PHYSICIAN DISCORDANCE IN ASSESSMENT OF DISEASE ACTIVITY IN RHEUMATOID ARTHRITIS

Background:

In rheumatoid arthritis (RA), global disease activity is commonly assessed, from the patient’s and the physician’s perspective, through a 100mm VAS. Previous studies have commonly shown a considerable discrepancy between the patient’s and physician’s assessment.

Objectives:

This study aimed evaluating patient-physician discordance in the assessment of disease activity and to explore its determinants.

Methods:

Cross sectional study including RA patients (ACR/EULAR 2010 classification criteria), aged ≥ 18 years, followed in a single tertiary centre. Data were collected from the most recent evaluation including sociodemographic features, disease duration (years), disease activity (DAS 28 3V-PCR), tender and swollen joint count 0-28 (TJC and SJC), VAS-pain-patient, patient and physician global assessment (PGA and PhGA respectively), erythrocyte sedimentation rate (ESR), C-reactive protein (CPR), Health assessment questionnaire (HAQ) and EuroQol five-dimension scale (EQ5D). The discrepancy between patients and physicians (ΔPPhGA) was defined as PGA minus PhGA, and a difference > |20mm| was considered as “discordant”. A descriptive analysis was performed and variables described as proportions or means (+/- SD), as adequate. Correlation between ΔPPhGA and other variables was assessed through Pearson’s correlation and comparison between groups through t-test. Variables with p<0.05 or otherwise considered clinically relevant were included in multiple linear regression analysis to identify predictors for ΔPPhGA. A p≤0.05 was considered statistically significant.

Results:

In total, 467 patients with RA were included (81.2% female; mean age 63.9% ± 12.2 years). PGA and PhGA were discordant in 61.7% of the cases, the patient scoring higher than the physician in 95% of these cases. The proportion of concordance increased (p< 0.01) when considering only patients in remission (DAS 28 3V <2.6), (Graph 1). ΔPPhGA was moderately correlated with VAS-pain-patient (r = 0.59) and weakly correlated with SJC (r = -0.12), HAQ (r= 0.27), EQ5D (r = -0.28) and age (r = 0.21); all p<0.01. In multivariate analysis, VAS-pain-patient (β 0.74, 95% CI 0.62-0.88, p=0.00) and TJC (β 0.16, 95% CI 0.45-0.48, p=0.02) remained associated with a higher ΔPPhGA.

Conclusion:

Our study confirmed that a significant discrepancy between patients and physicians in the assessment of global disease activity is frequent in clinical practice, probably due to valorization of different parameters. This was much less pronounced among patients in remission. Higher VAS-pain-patient and TJC were independent predictors of greater discrepancy between patients and physician’s assessment.

Adherence to the recommended prevention strategies before and after a hip fragility fracture: what makes us go blind?

OBJECTIVES

Our main objective was to evaluate the percentage of patients under anti-osteoporotic treatment (OT) at the time of hip fracture (HF) and one and four years after the HF event. We compared these results with the percentage of patients who should be under treatment at all three stages, according to the recently published Portuguese cost-effectiveness recommendations (PCER) for OT. Data regarding occurrence of new fragility fractures and mortality were also determined, one and four years after the HF event. Our secondary objective was to evaluate characteristics of patients associated with OT at the time of hip fracture..

Patients hospitalized due to HF between May 1st and October 31st of 2013 in a single tertiary hospital, were selected for this study. Data regarding demographic, clinical features (including the clinical risk factors for fracture considered by FRAX®), level of independence in daily activities (Katz index), comorbidity (Charlson index) and OT were recorded at the time of the HF. The subsequent risk of fracture was estimated for each patient with FRAX® (without mineral bone density). Mortality and the percentage of patients receiving an OT prescription and suffering a new osteoporotic fracture, at one and four years after the HF event, were established.

RESULTS

One hundred and thirty patients were included, with a mean age of 81.6±8.6 years. At the time of the HF only 28(21.5%) of the patients were receiving some form of OT. According to PCER, 115(88.5%) of these patients should be undergoing treatment according to FRAX® estimated risk, 30(23.1%) based on previous fractures and 119(91.5%) based on either criteria. The score of comorbidities was negatively associated with the prescription of OT at baseline (OR=0.17 [0.05-0.53], p=0.011) while the level of independence in daily activities was associated with higher probability of being treated (OR=3.20 [1.30-7.89], p=0.003). At one year after the HF, 39/130(30%) of patients had died. Although, according to PCER, all the remaining patients should be under OT based on the history of HF, only 11/91(12.1%) had received an OT prescription and 5/91(5.5%) suffered a new osteoporotic fracture during this period. At four years after the HF, 65/130 (50%) of patients had died. Only 6 of the remaining 65 (9.2%) were receiving an OT prescription and 9/65(13.8%) had suffered an additional fractured.

CONCLUSIONS

Similar to other countries, the percentage of patients receiving OT at the time and especially after a HF is extremely low. Risk estimations with FRAX® and application of current PCER should allow clinicians to introduce appropriate primary and secondary preventive measures. Comorbidities and dependence seem to be important reasons for this undertreatment.
