We aimed to investigate muscle physical properties, strength, mass, physical performance, and the prevalence of sarcopenia in patients with axial spondylarthritis (axSpA) compared to the healthy ...controls (HC).
We performed a cross-sectional study on 54 participants: 27 patients with axSpA and 27 HC, matched by age, gender, and level of physical activity. Muscle physical properties (stiffness, tone and elasticity), muscle strength (five-times sit-to-stand 5STS test), muscle mass, physical performance (measured through gait speed) and sarcopenia were compared between the groups. Linear regression models were conducted allowing adjustment for relevant variables.
Patients with axSpA (mean age 36.5 (SD 7.5) years, 67% males, mean disease duration 6.5 (3.2) years) had no significant difference in segmental muscle stiffness, tone or elasticity, compared with the HC, despite showing a slight numerically higher lower lumbar (L3-L4) stiffness median 246.5 (IQR 230.5-286.5) vs. 232.5 (211.0-293.5), p=0.38. No participants presented sarcopenia. Patients with axSpA, compared to the HC, had lower total strength B=1.88 (95% CI 0.43;3.33), as well as lower strength in the upper (B=-17.02 (-27.33;-6.70) and lower limbs B=-11.14 (-18.25;-4.04), independently of muscle physical properties. Patients had also significantly lower gait speed than the HC B=-0.11 (-0.21;-0.01), adjusted for muscle mass, strength and muscle physical properties.
Young axSpA patients with a relatively short disease duration presented similar segmental muscle physical properties as the HC and had no sarcopenia. Patients with axSpA had reduced physical performance and lower strength compared to the HC, despite normal muscle mass, suggesting a possible muscle dysfunction. Gait characteristics may be a potential biomarker of interest in axSpA.
Compelling evidence supports a treat-to-target (T2T) strategy for optimal outcomes in rheumatoid arthritis (RA). There is limited knowledge regarding the factors that impede implementation of T2T, ...particularly in a setting where adherence to T2T is protocol-specified. We aimed to assess clinical factors that associate with failure to adhere to T2T.
Patients with RA from 10 countries who were starting or changing conventional synthetic disease-modifying antirheumatic drugs and/or starting tumor necrosis factor inhibitors were followed for 2 years. Participating physicians were required per protocol to adhere to the T2T strategy. Factors influencing adherence to T2T low disease activity (T2T-LDA; 44-joint count Disease Activity Score ≤ 2.4) were analyzed in 2 types of binomial generalized estimating equations models: (1) including only baseline features (baseline model); and (2) modeling variables that inherently vary over time as such (longitudinal model).
A total of 571 patients were recruited and 439 (76.9%) completed 2-year followup. Failure of adherence to T2T-LDA was noted in 1765 visits (40.5%). In the baseline multivariable model, a high number of comorbidities (OR 1.10, 95% CI 1.02-1.19), smoking (OR 1.32, 95% CI 1.08-1.63) and high number of tender joints (OR 1.03, 95% CI 1.02-1.04) were independently associated with failure to implement T2T, while anticitrullinated protein antibody/rheumatoid factor positivity (OR 0.63, 95% CI 0.50-0.80) was a significant facilitator of T2T. Results were similar in the longitudinal model.
Lack of adherence to T2T in the RA BIODAM cohort was evident in a substantial proportion despite being a protocol requirement, and this could be predicted by clinical features. Rheumatoid Arthritis (RA) BIODAM cohort; ClinicalTrials.gov: NCT01476956.
ObjectivesTo estimate the national prevalence of rheumatic and musculoskeletal diseases (RMDs) in the adult Portuguese population and to determine their impact on health-related quality of life ...(HRQoL), physical function, anxiety and depression.MethodsEpiReumaPt is a national health survey with a three-stage approach. First, 10 661 adult participants were randomly selected. Trained interviewers undertook structured face-to-face questionnaires that included screening for RMDs and assessments of health-related quality of life, physical function, anxiety and depression. Second, positive screenings for ≥1 RMD plus 20% negative screenings were invited to be evaluated by a rheumatologist. Finally, three rheumatologists revised all the information and confirmed the diagnoses according to validated criteria. Estimates were computed as weighted proportions, taking the sampling design into account.ResultsThe disease-specific prevalence rates (and 95% CIs) of RMDs in the adult Portuguese population were: low back pain, 26.4% (23.3% to 29.5%); periarticular disease, 15.8% (13.5% to 18.0%); knee osteoarthritis (OA), 12.4% (11.0% to 13.8%); osteoporosis, 10.2% (9.0% to 11.3%); hand OA, 8.7% (7.5% to 9.9%); hip OA, 2.9% (2.3% to 3.6%); fibromyalgia, 1.7% (1.1% to 2.1%); spondyloarthritis, 1.6% (1.2% to 2.1%); gout, 1.3% (1.0% to 1.6%); rheumatoid arthritis, 0.7% (0.5% to 0.9%); systemic lupus erythaematosus, 0.1% (0.1% to 0.2%) and polymyalgia rheumatica, 0.1% (0.0% to 0.2%). After multivariable adjustment, participants with RMDs had significantly lower EQ5D scores (β=−0.09; p<0.001) and higher HAQ scores (β=0.13; p<0.001) than participants without RMDs. RMDs were also significantly associated with the presence of anxiety symptoms (OR=3.5; p=0.006).ConclusionsRMDs are highly prevalent in Portugal and are associated not only with significant physical function and mental health impairment but also with poor HRQoL, leading to more health resource consumption. The EpiReumaPt study emphasises the burden of RMDs in Portugal and the need to increase RMD awareness, being a strong argument to encourage policymakers to increase the amount of resources allocated to the treatment of rheumatic patients.
To establish the predictive validity of the Assessment of SpondyloArthritis international Society (ASAS) spondyloarthritis (SpA) classification criteria.
22 centres (N=909 patients) from the initial ...29 ASAS centres (N=975) participated in the ASAS-cohort follow-up study. Patients had either chronic (>3 months) back pain of unknown origin and age of onset below 45 years (N=658) or peripheral arthritis and/or enthesitis and/or dactylitis (N=251). At follow-up, information was obtained at a clinic visit or by telephone. The positive predictive value (PPV) of the baseline classification by the ASAS criteria was calculated using rheumatologist's diagnosis at follow-up as external standard.
In total, 564 patients were assessed at follow-up (345 visits; 219 telephone) with a mean follow-up of 4.4 years (range: 1.9; 6.8) and 70.2% received a SpA diagnosis by the rheumatologist. 335 patients fulfilled the axial SpA (axSpA) or peripheral SpA (pSpA) criteria at baseline and of these, 309 were diagnosed SpA after follow-up (PPV SpA criteria: 92.2%). The PPV of the axSpA and pSpA criteria was 93.3% and 89.5%, respectively. The PPV for the 'clinical arm only' was 88.0% and for the 'clinical arm'±'imaging arm' 96.0%, for the 'imaging arm only' 86.2% and for the 'imaging arm'+/-'clinical arm' 94.7%. A series of sensitivity analyses yielded similar results (range: 85.1-98.2%).
The PPV of the axSpA and pSpA criteria to forecast an expert's diagnosis of 'SpA' after more than 4 years is excellent. The 'imaging arm' and 'clinical arm' of the axSpA criteria have similar predictive validity and are truly complementary.
Objective
To assess whether using ultrasound (US) in addition to clinical information versus only clinical information in a treat-to-target (T2T) strategy leads to more clinical remission and to less ...radiographic progression in RA.
Methods
Patients with RA from the 2-year prospective BIODAM cohort were included. Clinical and US data (US7-score) were collected every 3 months and hands and feet radiographs every 6 months. At each visit, it was decided whether patients were treated according to the clinical definition of T2T with DAS44 remission as benchmark (T2T-DAS44). T2T-DAS44 was correctly applied if: (i) DAS44 remission had been achieved or (ii) if not, treatment was intensified. A T2T strategy also considering US data (T2T-DAS44-US) was correctly applied if: (i) both DAS44 and US remission (synovitis-score < 2, Doppler-score = 0) were present; or (ii) if not, treatment was intensified. The effect of T2T-DAS44-US on attaining clinical remission and on change in Sharp-van der Heijde score compared to T2T-DAS44 was analysed.
Results
A total of 1016 visits of 128 patients were included. T2T-DAS44 was correctly followed in 24% of visits and T2T-DAS44-US in 41%. DAS44 < 1.6 was achieved in 39% of visits. Compared to T2T-DAS44, using the T2T-DAS44-US strategy resulted in a 41% lower likelihood of DAS44 remission OR (95% CI): 0.59 (0.40;0.87) and had no effect on radiographic progression β(95% CI): 0.11 (− 0.16;0.39) assessed at various intervals up to 12 months later.
Conclusion
Our results do not suggest a benefit of using the US7-score in addition to clinical information as a T2T benchmark compared to clinical information alone.
Key Points
•
Ultrasound has a valuable role in diagnostic evaluation of rheumatoid arthritis, but it is unclear whether adding ultrasound to the clinical assessment in a treat-to-target (T2T) strategy leads to more patients achieving remission and reduction in radiographic progression.
•
Our data from a real-world study demonstrated that adding information from ultrasound to the clinical assessment in a T2T strategy led to a lower rather than a higher likelihood of obtaining clinical remission as compared to using only clinical assessment.
•
Our data demonstrated that adding ultrasound data to a T2T strategy based only on clinical assessment did not offer additional protection against radiographic progression in patients with RA.
•
Adding US to a T2T strategy based on clinical assessment led to far more treatment intensifications (with consequences for costs and exposure to adverse events) without yielding a meaningful clinical benefit.
To evaluate the performance of the referral strategy (RS) for SpA of a nationwide epidemiological study (EpiReumaPt), as compared with previously proposed RSs.
EpiReumaPt was a three-stage national ...epidemiologic study. In phase one, 10 661 adult participants were randomly selected and screened for rheumatic and musculoskeletal diseases. In the second phase, positive screenings for ⩾1 rheumatic and musculoskeletal disease plus 20% negative screenings were assessed by a rheumatologist. Finally, three rheumatologists revised all the information and defined the final diagnosis. All participants from phase two were included. Thirteen RS were tested against the SpA diagnosis using several metrics, including sensitivity, specificity, the post-test probability of SpA given a positive RS (positive predictive value) and given a negative RS (1 - negative predictive value).
From the total 3877 participants, 92 received a SpA diagnosis weighted national prevalence: 1.6% (95% confidence interval: 1.2, 2.1). Modified versions of the Assessment of SpondyloArthritis international Society-RS and EpiReumaPt-RS were the most sensitive (85% and 72%, respectively) and yielded the lowest post-test probabilities of SpA if negative (0.6% and 0.7%, respectively). Considering the national prevalence (pre-test probability) of SpA (1.6%), a negative screening by these two RSs decreased the probability of SpA substantially (Assessment of SpondyloArthritis international Society: -63%; EpiReumaPt: -56%). Other RSs performed less well in reducing disease probability (range: -6.3%; -37.5%). Overall, the probability of SpA given a positive RS was small (positive predictive value range: 2.2%; 7.6%) and the EpiReumaPt RS yielded the best balance between sensitivity and positive predictive value.
The proposed EpiReumaPt RS performed the best as a screening tool for SpA in patients from the general population when laboratory and imaging data were not available.
Abstract
Objective
To compare the performance of different spinal radiographic damage scoring methods in patients with early axial spondyloarthritis (axSpA).
Methods
Five-year spinal radiographs from ...the DESIR cohort were scored by three readers (averaged) for the calculation of the Stoke AS Spine Score (SASSS), modified Stoke Ankylosing Spondylitis Spine Score (mSASSS), Radiographic AS Spinal Score (RASSS), BASRI-spine and BASRI-total, and following the OMERACT filter, scores were compared according to truth, discrimination (reliability and sensitivity to change) and feasibility. The proportion of patients with a net change > smallest detectable change and >1 was calculated. The proportion of total variance explained by the patient (true variance) was calculated for the change scores as a measure of reliability, using analysis of variance.
Results
In total 699 patients were included. Five-year net changes > smallest detectable change (>1) were: RASSS 17% (17%), mSASSS 12% (12%), BASRI-spine and BASRI-total 12% (9%), SASSS 11% (11%). The mSASSS and the RASSS performed the best in terms of capturing the signal (positive change) related to noise (negative change). The proportion of variance explained by the patient was highest for the mSASSS and RASSS (85% for both 5-year progression scores vs 50-55% for other methods). The proportion of patient variance in the thoracic segment of the RASSS was unsatisfactory (46% for progression).
Conclusion
The existing scoring methods to assess spinal radiographic damage performed well in early phases of axSpA. The mSASSS and RASSS captured most change. There was no clear gain in additionally scoring the thoracic spine for the RASSS. The mSASSS remains the most sensitive and valid scoring method in axSpA, including early phases of the disease.
Hypereosinophilia is unusual in rheumatoid arthritis (RA), but can occur in severe long-lasting disease, especially in patients with extra-articular manifestations and high titers of rheumatoid ...factor (RF). The association of RA and hypereosinophilic syndrome (HES) remains yet poorly known. We present a case of a 46 years old woman with long-standing untreated RA, that presented to emergency department with severe symptoms of constrictive pericarditis with cardiac tamponade and bilateral pleural effusion, that progressed to cardiac arrest, associated to symmetrical polyarthritis and pruritic erythematous skin papules. She was submitted to urgent pericardial drainage and partial pericardiotomy. Laboratory analyses revealed hypereosinophilia, and elevated inflammatory parameters and immunoglobulin E. The histological study of the pericardium showed results consistent with inflammatory fibrinous pericarditis. Taking into account the presence of some characteristics that are usually present in cases of reactive HES instead of idiopathic HES, and after an intensive diagnostic study, that could rule out other potential causes of secondary HES, the diagnosis of HES associated with RA was made. She started glucocorticoids during hospitalization and methotrexate 15mg per week at the first outpatient rheumatology visit. After 12 weeks of treatment, we considered that she was in clinical and analytical remission, consistently maintaining that after a complete tapering of glucocorticoids. This case illustrates that clinicians should be aware that HES (including severe life-threatening cases) can occur in patients with RA, especially in cases of long-lasting disease with high titters of RF and without treatment, even in the absence of extra-articular features.
To estimate the disease specific prevalence of undiagnosed rheumatic and musculoskeletal diseases (RMDs) in Portugal and determine if people with undiagnosed RMDs have worse quality of life, physical ...function and higher health resources consumption, than people without RMDs.
A subgroup analysis of EpiReumaPt was made that included all participants≥18 years evaluated by a rheumatologist. Participants were stratified into three groups: undiagnosed RMDs; previously diagnosed RMDs; non-RMDs. A descriptive analysis of the three groups was performed. To estimate the prevalence of undiagnosed RMDs, weighted proportion were computed considering the sample design. The three groups were compared (Undiagnosed RMDs vs non-RMDs; Previously diagnosed RMDs vs non-RMDs) for health related quality of life (HRQoL) (EQ5D), physical function (HAQ), mental health (HADS) and health resources consumption. The effect of being undiagnosed for these outcomes was assessed in multivariable models adjusted for age, gender, geographical region and years of education (reference: non-RMD).
A total of 3877 participants were included. The prevalence of undiagnosed RMDs was 29%. Compared to participants without RMDs, undiagnosed participants had lower HRQoL (EQ-5D: β (95% CI)=-0.07 (-0.103,-0.043)) and physical function (HAQ: β (95% CI)=0.10 (0.05, 0.15)), more anxiety (OR (95% CI)=2.3 (1.4, 3.7)) and depression symptoms (OR (95% CI)=1.4 (0.8, 2.4)). Undiagnosed RMDs participants were more likely to visit an orthopedist (OR (95% CI)=2.0 (1.1, 3.5)) and had a higher number of orthopedic appointments (IRR (95% CI)=2.5 (1.3, 4.9)) than participants without RMDs.
Patients with undiagnosed RMDs are frequent in Portugal, have worse HRQoL, physical function and mental health than people without RMDs. Undiagnosed patients are nonetheless consumers of health resources and tend to seek help from specialties other than rheumatology. Increasing the awareness of RMDs might promote their early identification and treatment leading to both personal and societal benefits.
