Disease activity and widespread pain are main contributors to patient-reported global health in axial spondyloarthritis: an analysis of 6064 patients. Rheumatol Int 2024:10.1007/s00296-024-05576-7. [PMID: 38597981 DOI: 10.1007/s00296-024-05576-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 03/02/2024] [Indexed: 04/11/2024]
Abstract
Global health (GH) and health-related quality of life are patient priorities in axial spondyloarthritis (axSpA). Our objective was to assess the relative importance of disease-related factors including disease activity, and patient-related factors including comorbidities, to explain GH in axSpA. Post hoc cross-sectional analyses of 4 sets (COMOSPA, PERSPA, COMEDSPA, and DESIR) of patients fulfilling ASAS criteria for axSpA. GH was assessed through the ASAS Health Index (ASAS-HI) or the EuroQoL-5D-3L (EQ-5D). Disease-related factors included disease activity (ASDAS, psoriasis, arthritis, enthesitis, and CRP), disease duration, diagnostic delay, bamboo spine, and treatment. Non-disease-related factors included sociodemographic characteristics, comorbidities and chronic widespread pain. Multivariable logistic and linear regressions and partial variances (R2) were applied to identify independent determinants of GH. In 6064 patients (range 284-2756 across datasets), mean age ranged 38.9-45.8 years, 51-68% were male. GH was generally moderate: median ASAS-HI ranged 5.0-7.0. GH was explained by ASDAS (range of odds ratios, OR, 2.60-4.48) and chronic widespread pain (range of OR 2.19-8.39); other determinants included comorbidities and sociodemographic characteristics. Only 47-57% of the total variance in GH could be explained by the models; disease activity (partial variance, 16-26%) and chronic widespread pain (partial variance 12-15%) were the key contributing variables. A wide range of disease and non-disease-related variables usually collected in studies could only explain 47-57% of the variability in GH. Among these, disease activity and chronic widespread pain were most relevant and of similar magnitude of importance. These findings will be helpful for shared decision-making.

Measuring response to treatment in axial spondyloarthritis using quantitative imaging biomarkers: a prospective observational cohort study. Br J Radiol 2023; 96:20220530. [PMID: 37751217 PMCID: PMC10646635 DOI: 10.1259/bjr.20220530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 09/13/2023] [Accepted: 09/19/2023] [Indexed: 09/27/2023] Open
Abstract
OBJECTIVE Objective assessments of disease activity and response to treatment in axial spondyloarthritis (axSpA) remain a challenge; quantitative imaging biomarkers (QIBs) of inflammation could enhance assessments of disease activity and therapeutic response. We aimed to determine the responsiveness of QIBs obtained from diffusion-weighted imaging (DW-MRI) and chemical shift-encoded MRI (CSE-MRI) using the partially automated Bone Edema and Adiposity Characterisation with Histograms (BEACH) software tool in axSpA patients undergoing biologic therapy. METHODS We conducted a prospective longitudinal cohort study, including 30 patients with axSpA undergoing biologic therapy. Patients were scanned before and after biologic therapy using conventional MRI, DWI and CSE-MRI at 3T. Apparent diffusion coefficient (ADC) and proton density fat fraction (PDFF) were assessed using the BEACH tool (https://github.com/TJPBray/BEACH), and conventional MR images were assessed using established visual scoring methods by expert radiologists. Responsiveness - the ability of the MRI measurements to capture changes in disease occurring as a result of biologic therapy - was assessed using the standardized response mean (SRM). Inter-reader reliability of the ADC and PDFF maps was assessed using Bland-Altman limits of agreement analysis and the intraclass correlation coefficient. RESULTS Responsiveness to therapy was moderate for ADC-based parameters (SRM 0.50) and comparable to established visual scoring methods for bone marrow oedema (SRM 0.53). Interobserver variability was lower for QIBs compared with conventional visual scores methods. CONCLUSIONS QIBs measured using the BEACH tool are sensitive to changes in inflammation in axSpA following biologic therapy, with similar responsiveness and lower interobserver variability to visual scoring by expert radiologists. ADVANCES IN KNOWLEDGE QIBs measured using the partially automated BEACH tool offer an objective measure of response to biologic therapy in axSpA.

Assessment of axial spondyloarthritis activity using a magnetic resonance imaging-based multi-region-of-interest fusion model. Arthritis Res Ther 2023; 25:227. [PMID: 38001465 PMCID: PMC10668377 DOI: 10.1186/s13075-023-03193-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Accepted: 10/13/2023] [Indexed: 11/26/2023] Open
Abstract
BACKGROUND Identifying axial spondyloarthritis (axSpA) activity early and accurately is essential for treating physicians to adjust treatment plans and guide clinical decisions promptly. The current literature is mostly focused on axSpA diagnosis, and there has been thus far, no study that reported the use of a radiomics approach for differentiating axSpA disease activity. In this study, the aim was to develop a radiomics model for differentiating active from non-active axSpA based on fat-suppressed (FS) T2-weighted (T2w) magnetic resonance imaging (MRI) of sacroiliac joints. METHODS This retrospective study included 109 patients diagnosed with non-active axSpA (n = 68) and active axSpA (n = 41); patients were divided into training and testing cohorts at a ratio of 8:2. Radiomics features were extracted from 3.0 T sacroiliac MRI using two different heterogeneous regions of interest (ROIs, Circle and Facet). Various methods were used to select relevant and robust features, and different classifiers were used to build Circle-based, Facet-based, and a fusion prediction model. Their performance was compared using various statistical parameters. p < 0.05 is considered statistically significant. RESULTS For both Circle- and Facet-based models, 2284 radiomics features were extracted. The combined fusion ROI model accurately differentiated between active and non-active axSpA, with high accuracy (0.90 vs.0.81), sensitivity (0.90 vs. 0.75), and specificity (0.90 vs. 0.85) in both training and testing cohorts. CONCLUSION The multi-ROI fusion radiomics model developed in this study differentiated between active and non-active axSpA using sacroiliac FS T2w-MRI. The results suggest MRI-based radiomics of the SIJ can distinguish axSpA activity, which can improve the therapeutic result and patient prognosis. To our knowledge, this is the only study in the literature that used a radiomics approach to determine axSpA activity.

The natural history of chronic widespread pain in patients with axial spondyloarthritis: a cohort study with clinical and self-tracking data. Rheumatology (Oxford) 2023; 62:2444-2452. [PMID: 36469303 DOI: 10.1093/rheumatology/keac679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Accepted: 11/19/2022] [Indexed: 07/20/2023] Open
Abstract
OBJECTIVES This study investigates longitudinal patterns, predictors and long-term impact of pain in axial spondyloarthritis (axSpA), using clinical and self-tracking data. METHODS The presence of multisite pain (MSP), affecting at least six of nine body regions using a Margolis pain drawing, and subsequent chronic widespread pain (CWP), MSP at more than one timepoint, was assessed in a cohort of axSpA patients. Incident MSP (MSP at two consecutive visits or more), intermittent MSP (MSP at two or more non-consecutive visits) and persistent MSP (MSP at each visit) were described. Demographic, clinical and self-tracking measures were compared for the CWP vs non-CWP groups using Students t test, Wilcoxon-Mann-Whitney and χ2 test for normal, non-normal and categorical data, respectively. Predictors of CWP were evaluated using logistic regression modelling. RESULTS A total of 136 patients, mean clinical study duration of 120 weeks (range 27-277 weeks) were included, with sufficient self-tracking data in 97 patients. Sixty-eight (50%) patients reported MSP during at least one clinical visit: eight (6%) incident MSP; 16 (12%) persistent MSP; and 44 (32%) intermittent MSP. Forty-six (34%) of the cohort had CWP. All baseline measures of disease activity, function, quality of life, sleep disturbance, fatigue and overall activity impairment were significant predictors of the development of CWP. BASDAI and BASFI scores were significantly higher in those with CWP and self-tracking data revealed significantly worse pain, fatigue, sleep quality and stress. CONCLUSIONS The development of CWP is predicted by higher levels of disease activity and burden at baseline. It also impacts future disease activity and wellbeing.

Coexistence of fibromyalgia syndrome and inflammatory rheumatic diseases, and autonomic cardiovascular system involvement in fibromyalgia syndrome. Clin Rheumatol 2023; 42:645-652. [PMID: 36151442 DOI: 10.1007/s10067-022-06385-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Revised: 09/16/2022] [Accepted: 09/20/2022] [Indexed: 11/03/2022]
Abstract
The spectrum of symptoms represented by fibromyalgia syndrome (FMS) has a profound effect on daily activities and impairs the quality of life. A considerable proportion of patients with inflammatory rheumatic diseases (IRDs) fulfill the FMS criteria, which can complicate the diagnosis, treatment, and follow-ups of IRD. In addition, the coexistence of FMS may cause unnecessary laboratory and radiological assessments. Several mechanisms have been proposed that may have a role in the etiopathogenesis of FMS, one of which is autonomic dysregulation. In studies evaluating cardiac autonomic dysfunction based on heart rate variability (HRV), there has been found to be a decrease in HRV and dominance of the sympathetic nervous system. Autonomic reactivity reflects modulations of several functions to overcome the existing state and conditions. Blunted autonomic reactivity has been found in some FMS patients, which makes it difficult for these patients to respond appropriately to unexpected stress sources that occur during daily living activities. Baroreceptor signals have an inhibitory influence on the central nervous system, and these impulses cause pain suppression. From this perspective, there are studies that have suggested the involvement of diminished baroreflex sensitivity in the etiology of FMS. The risk of endothelial dysfunction and increased arterial stiffness have been shown to occur in FMS patients due to autonomic dysfunction, sympathetic nervous system dominance, chronic stress, and pain. There is also evidence linking FMS with the risk of atrial and ventricular arrhythmias. Considering all these cardiovascular autonomic dysfunctions, tests that can confirm abnormalities should be performed when suspicion arises. There is a need for specific pharmacological and non-pharmacological treatment alternatives to be identified for subgroups of patients with cardiovascular system abnormalities. Key points • The frequency of FMS accompanying inflammatory rheumatic diseases is considerable and this coexistence leads to troubles in evaluating treatment response and determining appropriate medical treatment options in inflammatory rheumatic diseases. • Various cardiovascular autonomic abnormalities have been described in FMS patients. Among these, the most emphasized are autonomic dysfunction, the disruption of the balance between the sympathetic-parasympathetic nervous systems, blunted autonomic reactivity to acute stress, changes in baroreflex sensitivity, increased arterial stiffness, and electrophysiological alterations. • Autonomic cardiovascular dysfunction may be involved in the complex etiopathogenesis of the fibromyalgia syndrome and may trigger at least some symptoms.

Neuropathic pain in axial spondyloarthropathy is underdiagnosed and a confounding factor in biologic drug-switching decision: a cross-sectional study. Clin Rheumatol 2023; 42:1275-1284. [PMID: 36746834 DOI: 10.1007/s10067-023-06531-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 01/25/2023] [Accepted: 01/28/2023] [Indexed: 02/08/2023]
Abstract
OBJECTIVES The aim of this study was to evaluate the relationship between the presence of neuropathic pain (NeP), disease activity scores and biologic drug-switching decisions in the subjects with axial spondyloarthritis (axSpA) receiving biologic treatment. METHODS PainDETECT Questionnaire was used to evaluate the presence of NeP in the patients with axSpA aged ≥18 years who had been receiving biologic treatment for at least 6 months. The relationships between disease activity scores, inflammatory markers, life quality index, biologic drug-switching decisions and the presence of NeP were analyzed. RESULTS A total number of 175 patients with axSpA [ankylosing spondylitis (AS) (n:150) and non-radiographic axSpA (nr-axSpA) (n:25)] were enrolled in the study. NeP was detected in 41.7% of the patients and it was more common in females than in males (p:0.009). PainDETECT scores were positively correlated with disease activity scores, but they were not correlated with inflammatory marker levels. NeP was found to be significantly more common in whom the biologics had been switched 3 or more times (p:0.007). PainDETECT scores were higher and NeP was more prevalent (p:0.028) in the patients for whom drug-switching decisions had been made due to primary or secondary unresponsiveness. CONCLUSION NeP is more common than estimated in the patients with axSpA and current disease activity scores are insufficient to make a distinction between NeP and inflammatory pain. NeP is a confounding factor in the evaluation of treatment response to biologic agents. In the subjects with AS and nr-axSpA with primary or secondary treatment unresponsiveness, the presence of NeP must be considered before biologic drug-switching decisions. Key Points • Neuropathic pain (NeP) is common in subjects with AxSpA treated with multiple biologic agents. • Current disease activity scores for AxSpA are insufficient to make a differentiation between NeP and inflammatory pain. • NeP is a confounding factor in the evaluation of treatment response to biologic agents. • Patients with AxSpA should be re-evaluated in terms of the presence of neuropathic pain before making biologic drug-switching decisions.

Nonradiographic axial spondyloarthritis: expanding the spectrum of an old disease: A narrative review. Medicine (Baltimore) 2022; 101:e29063. [PMID: 35475794 PMCID: PMC9276084 DOI: 10.1097/md.0000000000029063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Accepted: 02/24/2022] [Indexed: 01/04/2023] Open
Abstract
Nonradiographic axial spondyloarthritis (nr-axSpA) represents a distinct phenotype within the spectrum of axial spondyloarthritis (axSpA), which is characterized by a range of clinical manifestations. Despite a high disease burden that is comparable to ankylosing spondylitis (also known as radiographic axSpA), there is an unmet need to recognize and effectively manage patients with active nr-axSpA.A targeted literature search was conducted in OVID (MEDLINE and Embase databases) to identify articles on nr-axSpA, including its definition, demographics, epidemiology, burden, diagnosis, clinical presentation, and treatment guidelines.The lack of adequate epidemiological data and incomplete understanding of nr-axSpA among rheumatologists and nonrheumatologists contributes to delayed referrals and diagnosis. This delay results in a substantial burden on patients, physically and psychologically, and the healthcare system. Targeted therapies, such as biologics, including inhibitors of tumor necrosis factor or interleukin-17A, have been approved and utilized for the management of nr-axSpA, and other novel therapeutics with different mechanisms of action are in development. Raising awareness among US internists regarding the prevalence of nr-axSpA, disease burden, clinical presentation, diagnostic tools, and available treatments is important for improved disease management.Future clinical investigations focusing on the development of markers that aid early diagnosis and predict treatment response may also improve the management of nr-axSpA. This review provides an overview of nr-axSpA with the aim of raising awareness of the disease among US internists, with an overarching goal to contribute toward the improved recognition and timely referral of these patients to rheumatologists for diagnosis and management.

Abstract
OBJECTIVES This study aimed to compare the demographic characteristics, disease activity, functional status, and quality of life between patients with axial spondyloarthritis and fibromyalgia and patients with axial spondyloarthritis without fibromyalgia. METHODS We searched MEDLINE via PubMed, Cochrane, Scopus, and Embase databases, from the earliest available indexing date to March 30, 2019, for comparative studies evaluating fibromyalgia in patients with axial spondyloarthritis. Two authors extracted data independently, and all discrepancies were resolved through consensus. RESULTS Seven comparative studies were identified. No statistically significant differences were observed in terms of age, levels of inflammatory markers, and prevalence of extra-articular manifestations such as uveitis, psoriasis, and inflammatory bowel disease between patients with Axial spondyloarthritis fibromyalgia and those without it. Sex ratios (female to male) were approximately 3:2 and 1:3 in patients with and without fibromyalgia, respectively. The ratios concerning human leukocyte antigen B27-positive patients with and without fibromyalgia were 45.1% and 65.6%, respectively. Patients with fibromyalgia had significantly higher Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Functional Index, and Ankylosing Spondylitis Quality of Life scores. CONCLUSIONS Our meta-analysis showed that patients with Axial spondyloarthritis fibromyalgia had considerably higher pain severity, disease activity, and worse quality of life than patients without fibromyalgia. The sex ratios (female to male) were approximately 3:2 and 1:3, and ratios for human leukocyte antigen B27-positive patients were 45.1% and 65.6% in patients with and without fibromyalgia, respectively. Further well-designed studies are needed to substantiate our results.

Abstract
OBJECTIVES In axial spondyloarthritis (axSpA), switching between multiple biologic or targeted synthetic (b/ts-) DMARDs might indicate difficult-to-treat disease. We aimed to explore the occurrence of multiple switching in routine care axSpA patients using various definitions, and to identify associated clinical characteristics upon start of first b/tsDMARD (baseline). METHODS Observational cohort study including patients with axSpA starting a first-ever b/tsDMARD 2009-2018 based on data from five biologic registries (Denmark/Sweden/Finland/Norway/Iceland). Comorbidities and extra-articular manifestations were identified through linkage to national registries. Multi-switching was defined in overlapping categories according to b/tsDMARD treatment history: treatment with ≥3 b/tsDMARDs, ≥4 or ≥ 5 b/tsDMARDs during follow-up. We explored the cumulative incidence of patients becoming multi-switchers with ≥3 b/tsDMARDs stratified by calendar-period (2009-11/2012-13/2014-15/2016-2018). In the subgroup of patients starting a first b/tsDMARD 2009-2015, baseline characteristics associated with multi-switching (within 3 years' follow-up) were explored using multiple logistic regression analyses. RESULTS Among 8,398 patients included, 6,056 patients (63% male, median age 42 years) started a first b/tsDMARD 2009-2015, whereof proportions treated with ≥3, ≥4 or ≥ 5 b/tsDMARDs within 3 years' follow-up were 8%, 3%, 1%, respectively.Calendar-period did not affect the cumulative incidence of multi-switching.Baseline characteristics associated with multi-switching (≥3 b/tsDMARDs) were female gender, shorter disease duration, higher patient global score, comorbidities, and having psoriasis but not uveitis. CONCLUSION In this large Nordic observational cohort of axSpA patients, multiple switching was frequent with no apparent time-trend. Clinical associated factors included gender, but also previous comorbidities and extraarticular manifestations illustrating the ongoing challenge of treating this patient group.

Abstract
BACKGROUND Fibromyalgia (FM) is common among patients with ankylosing spondylitis (AS), and its coexistence is believed to interfere with the measurement of patient-reported outcomes of disease activity and function in AS because of overlapping symptoms between the 2 diseases. This can confound clinical assessment and treatment decisions. AIMS The aim of this study was to assess the relationship between the Fibromyalgia Symptom Scale (FSS) and its components, the Widespread Pain Index (WPI), and System Severity Scale with measures of disease activity, function, and patient-reported outcomes in AS. METHODS We recruited 63 AS patients (aged ≥18 years) meeting the modified New York criteria, and Bath Ankylosing Spondylitis Disease Activity Index, Ankylosing Spondylitis Disease Activity Score-C-Reactive Protein, Routine Assessment of Patient Index Data 3, and Bath Ankylosing Spondylitis Functional Index questionnaires were administered to them. The presence of FM was determined using validated 2010 American College of Rheumatology diagnostic criteria for FM. RESULTS Twenty-eight of 63 patients (44.4%) with AS and FM had higher disease activity and greater impairment of functional ability compared with AS patients without FM. Using multiple linear regression estimates, there was no significant relationship of FSS scores with Bath Ankylosing Spondylitis Disease Activity Index (p = 0.36), Routine Assessment of Patient Index Data 3 (p = 0.50), Ankylosing Spondylitis Disease Activity Score-C-Reactive Protein (p = 0.24), Bath Ankylosing Spondylitis Functional Index (p = 0.42) scores, or erythrocyte sedimentation rate (p = 0.82) and C-reactive protein (p = 0.75). CONCLUSIONS Despite a high prevalence of FM in our patients with the diagnosis of AS, there was no relationship between FSS and measures of disease activity or function in AS, suggesting that FSS and its components could be a useful tool to assess FM in AS patients. Also, FM impairs functional ability in patients with AS.

Fibromyalgia and Associated Disorders: From Pain to Chronic Suffering, From Subjective Hypersensitivity to Hypersensitivity Syndrome. Front Med (Lausanne) 2021; 8:666914.

Abstract
The concept of fibromyalgia has progressed to achieve a certain consensus regarding the definition of the condition. We summarize what is known in 2020, be it in terms of diagnosis, with the criteria that have changed over the years, or at the level of the psychological profile, via the notions of "catastrophizing" and "coping" and post-traumatic syndrome. The importance of fatigue and sleep disorders is underlined, with the chronological sequence of post-traumatic syndrome, chronic fatigue, and then amplification of the pain and the onset of multiple associated symptoms. The etiopathogenic debate has been enriched thanks to neuro-imaging data to discover the start of the central neurological signature. The many associated symptoms are reanalyzed in the context of so-called sister conditions which form sometimes more or less separate entities, such as chronic fatigue syndrome or restless legs syndrome for example. What these conditions have in common is hypersensitivity, not just to pain, but also to all exteroceptive stimuli, from deep sensitivity in the neuro-vegetative system, the sense organs and certain functions of the central nervous system, to the psychological aspects and sleep control. In summary, it is possible to define fibromyalgia as a cognitive disorder of cortical integration of chronic pain, with amplification of painful and sensory nociception, decrease in the threshold for the perception of pain, and persistence of a stimulus that maintains the process in chronicity. Fibromyalgia is part of a group of chronic hypersensitivity syndromes of central origin, with a very wide range of means of expression.

Abstract
Fibromyalgia syndrome (FMS) is common in patients of psoriatic arthritis (PsA), but the magnitude of its impact is uncertain. This cross-sectional study evaluated the impact of FMS on health-related quality of life (HRQoL) and disease activity in PsA. Adults classified with PsA (CASPAR criteria) at the rheumatology and dermatology outpatient clinics of PGIMER, Chandigarh, India between January 2014 and June 2015 were recruited. All patients were assessed for FMS using the 2010 ACR criteria. Health-related quality of life was assessed using PROMIS-HAQ, HAQ-pain, HAQ-health and revised fibromyalgia impact questionnaire (FIQR). Disease activity measures (SJC, TJC, BASDAI, enthesitis, dactylitis, PASI) and PROMIS-HAQ were correlated with measures of FMS [FIQR, symptom severity scale (SSS) score and widespread pain index (WPI)]. Multivariate regression analyses were used to identify predictors of PROMIS-HAQ and FMS. Out of 106 PsA patients screened, 102 [50 (49%) females; mean age 43.8 (12.4) years] were included. 19 (18.3%) had FMS. Patients of PsA with FMS had significantly (p < 0.05) higher TJC (14 vs 7), SJC (10 vs 5), BASDAI (6.1 vs 4.1) and enthesitis (53 vs 33%), but no difference in dactylitis, severity of skin disease and disease duration. A significant positive correlation of measures of FMS (FIQR, SSS and WPI) with SJC, TJC and BASDAI was noted. PROMIS-HAQ, HAQ-pain and HAQ-health were significantly worse (p < 0.001) in patients of PsA with coexisting FMS. Presence of FMS was found to be an independent predictor of worse PROMIS-HAQ. Female gender and higher TJC independently predicted presence of FMS. To conclude, FMS is an important contributor towards poor HRQoL in patients of PsA and is associated with higher values of joint disease activity measures.

Abstract
Objective Whether comorbidities influence disease activity assessment in axial SpA (axSpA) is unclear. Comorbidities inflate DAS28 in rheumatoid arthritis through the patient global score. We examined whether axSpA disease activity measures are differentially affected, and whether comorbidities inflate the AS disease activity score (ASDAS) through the patient global component. Methods We used baseline data from the British Society for Rheumatology Biologics Register for AS, including 14 physician diagnosed comorbidities. Linear models were used to compare disease activity (BASDAI, spinal pain, ASDAS) and ESR/CRP according to comorbidity count, adjusted for age, gender, BMI, smoking, socioeconomic status, and education. The same models were used to examine whether the patient global score was associated with comorbidities, additionally adjusting for other ASDAS components. Results The number of participants eligible for analysis was 2043 (67% male, mean age 49 years); 44% had at least one comorbidity. Each additional comorbidity was associated with higher BASDAI by 0.40 units (95% CI: 0.27, 0.52) and spinal pain by 0.53 (95% CI: 0.37, 0.68). Effect size for ASDAS (0.09 units; 95% CI: 0.03, 0.15) was not clinically significant. ESR and CRP were not associated with comorbidity count. Depression, heart failure and peptic ulcer were consistently associated with higher disease activity measures, but not CRP/ESR. Patient global was associated with comorbidity count, but not independently of other ASDAS components (P = 0.75). Conclusion Comorbidities were associated with higher patient reported disease activity in axSpA. Clinicians should be mindful of the potential impact of comorbidities on patient reported outcome measures and consider additionally collecting ASDAS when comorbidities are present.

Abstract
The conceptual paradigm of axial spondyloarthritis (axSpA) has evolved and now comprises an expanded spectrum that includes more females and patients with little or no radiographic changes in sacroiliitis or syndesmophyte formation in the spine.1 This broadened paradigm is often, but not always, characterized by an inflammatory magnetic resonance imaging (MRI) signature.

Reduction in movement-evoked pain and fatigue during initial 30-minute transcutaneous electrical nerve stimulation treatment predicts transcutaneous electrical nerve stimulation responders in women with fibromyalgia. Pain 2021; 162:1545-1555. [PMID: 33230010 PMCID: PMC8049882 DOI: 10.1097/j.pain.0000000000002144] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Accepted: 11/02/2020] [Indexed: 11/26/2022]
Abstract
ABSTRACT We previously showed that 1 month of transcutaneous electrical nerve stimulation (TENS) reduces movement-evoked pain and fatigue in women with fibromyalgia (FM). Using data from this study (Fibromyalgia Activity Study with TENS [FAST]), we performed a responder analysis to identify predictors of clinical improvement in pain and fatigue with TENS, validated these models using receiver operator characteristic, and determined number needed to treat and number needed to harm. Participants were randomly assigned to active-TENS (2-125 Hz; highest-tolerable intensity), placebo-TENS, or no-TENS for 1 month. At the end of the randomized phase, placebo-TENS and no-TENS groups received active-TENS for 1 month. The predictor model was developed using data from the randomized phase for the active-TENS group (n = 103) and validated using data from placebo-TENS and no-TENS groups after active-TENS for 1 month (n = 155). Participant characteristics, initial response to TENS for pain and fatigue, sleep, psychological factors, and function were screened for association with changes in pain or fatigue using a logistic regression model. Predictors of clinical improvement in pain were initial response to pain and widespread pain index (area under the curve was 0.80; 95% confidence interval: 0.73-0.87). Predictors of clinical improvement in fatigue were marital status, sleep impairment, and initial response to TENS (area under the curve was 0.67; 95% confidence interval: 0.58-0.75). Number needed to treat for pain and fatigue ranged between 3.3 and 5.3. Number needed to harm ranged from 20 to 100 for minor TENS-related adverse events. The response to an initial 30-minute TENS treatment predicts who responds to longer-term TENS use in women with FM, making this a clinically useful procedure. Number needed to treat and number needed to harm suggest that TENS is effective and safe for managing pain and fatigue in FM.

Abstract
Inflammatory back pain is characteristic of spondyloarthritis (SpA); however, this pain may not respond to treatment with NSAIDs or biologics. Pain is multifactorial and a combination of mechanical and inflammatory factors. A growing body of literature examines the impact of emotions on pain in SpA; many patients with this condition suffer from depression and fibromyalgia. Advanced imaging techniques can investigate the interplay of various brain networks in pain perception. Animal models have helped understand the interplay between the immune and nervous systems in pain generation and have highlighted differences in pain perception between the sexes.

The changing states of fibromyalgia in patients with axial spondyloarthritis: results from the British Society of Rheumatology Biologics Register for Ankylosing Spondylitis. Rheumatology (Oxford) 2021; 60:4121-4129. [PMID: 34469570 PMCID: PMC8409995 DOI: 10.1093/rheumatology/keaa888] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 11/14/2020] [Indexed: 12/16/2022] Open
Abstract
Objectives To identify factors associated with FM development and recovery in patients with axial SpA (axSpA). Methods The British Society of Rheumatology Biologics Register for Ankylosing Spondylitis (BSRBR-AS) recruited patients with axSpA from 83 centres in a prospective study. FM was diagnosed using the self-reported Fibromyalgia Survey Diagnostic Criteria from 2015. Measures of axSpA disease activity and clinical findings were recorded at regular intervals. We identified predictors for FM development and recovery between yearly visits using uni- and multivariable logistic regression models. Results A total of 801 participants, 247 (30.8%) female, had two or more visits and were eligible for inclusion. A total of 686 participants did not have FM at baseline, of whom 45 had developed FM at follow-up, while 115 participants had FM at baseline, of whom 77 had recovered at follow-up. A high baseline BASDAI score [odds ratio (OR) 1.27 (95% CI 1.08, 1.49)] and Widespread Pain Index (WPI) [OR 1.14 (95% CI 1.02, 1.28)] were significantly associated with FM development in the final multivariable model. A low baseline BASFI score [OR 0.68 (95% CI 0.53, 0.86)] and WPI [OR 0.84 (95% CI 0.720, 0.97)] and starting a TNF inhibitor [OR 3.86 (95% CI 1.54, 9.71)] were significantly associated with FM recovery. Conclusion High levels of disease activity and the presence of widespread pain is associated with the development of FM in patients with axSpA, while low levels of the same variables and starting a TNF inhibitor are associated with recovery from FM. The presence of comorbid FM should be considered in patients with persistent high axSpA disease activity and widespread pain.

Abstract
Objective The aim was to assess the feasibility and acceptability of a telephone-based cognitive behaviour therapy (tCBT) intervention for individuals with axial SpA (axSpA), with and without co-morbid FM, and to measure the change in patient-reported health outcomes. Methods A convenience sample of individuals recruited from British Society for Rheumatology Biologics Registry for AS (BSRBR-AS) sites were offered a course of tCBT (framed as coaching). Patient-reported outcomes were measured at baseline and on course completion. Semi-structured qualitative interviews assessed intervention acceptability. Thematic analysis was informed by the theoretical framework of acceptability. Results Forty-two participants attended for initial assessment. Those completing at least one tCBT session (n = 28) were younger, more likely to meet classification criteria for FM (57 vs 29%) and reported higher disease activity. Modest improvements were reported across a range of disease activity and wider health measures, with 62% of patients self-rating their health as improved (median 13 weeks post-intervention). Twenty-six participants were interviewed (including six who discontinued after initial assessment). tCBT was widely acceptable, offering a personalized approach. Despite low or unclear expectations, participants described improved sleep and psychological well-being and gained new skills to support self-management. Reasons for non-uptake of tCBT centred on lack of perceived need and fit with individual value systems. Many felt that tCBT would be most useful closer to diagnosis. Conclusion Higher uptake among axSpA patients with co-morbid FM suggests that these individuals have additional needs. The findings are helpful in identifying patients most likely to engage with and benefit from tCBT and to maximize participation.

Comorbid pain in axial spondyloarthritis, including fibromyalgia. Ther Adv Musculoskelet Dis 2020; 12:1759720X20966123.

Abstract
The main symptom in patients with axial spondyloarthritis (axSpA) is inflammatory back pain, caused principally by inflammation of the sacroiliac joints and the spine. However, not all back pain in patients with axSpA is related to active inflammation: other types of pain can occur in these patients, and may be related to structural damage (e.g. ankylosis), degenerative changes, vertebral fractures or comorbid fibromyalgia, which are not uncommon in these patients. Structural damage and ankylosis may lead to a biomechanical stress, which can lead to chronic mechanical pain; and degenerative changes of the spine may also exist in patients with axSpA also leading to mechanical pain. Osteoporosis is more prevalent in axSpA patients than in the general population, and vertebral fractures may result in acute bone pain, which can persist for several months. Fibromyalgia, which is also more prevalent in patients with chronic inflammatory diseases (including axSpA), presents with widespread pain which can mimic entheseal pain. A correct diagnosis of the origin of the pain is crucial, since treatments and management may differ considerably. Recognizing these causes of pain may be a challenge in clinical practice, especially for fibromyalgia, which can coexist with axSpA and may have a significant impact on biologic drug response. In this review, we provide an update of the most common causes of pain other than inflammatory back pain in axSpA patients, and we discuss the latest management options for such causes.

Differences between men and women with nonradiographic axial spondyloarthritis: clinical characteristics and treatment effectiveness in a real-life prospective cohort. Arthritis Res Ther 2020; 22:233.

Abstract
BACKGROUND Sex differences with regard to clinical manifestations and response to tumor necrosis factor inhibitors (TNFi) have been delineated for the radiographic form of axial spondyloarthritis (axSpA). More limited evidence for a differential effectiveness of treatment in genders exists for the nonradiographic disease state (nr-axSpA). The aim of the study was to compare demographics, clinical parameters, and response to TNFi in women versus men with nr-axSpA. METHODS We compared disease characteristics of 264 women and 231 men with nr-axSpA at inclusion in the prospective Swiss Clinical Quality Management Cohort. Response to a first TNFi was assessed in 85 women and 78 men without diagnosed co-morbid fibromyalgia. The primary outcome was the proportion of patients achieving the 40% improvement in the Assessment of SpondyloArthritis international Society criteria (ASAS40) at 1 year. Additional response outcomes were evaluated as secondary outcomes. Patients having discontinued TNFi were considered non-responders. Logistic regression analyses were adjusted for baseline differences, which might potentially mediate the effect of sex on treatment response. RESULTS Compared to men, women had a longer diagnostic delay, a higher level of perceived disease activity, and more enthesitis and were in a lower percentage HLA-B27 positive. An ASAS40 response was achieved by 17% of women and 38% of men (OR 0.34; 95% CI 0.12, 0.93; p = 0.02). A significantly lower response rate in women was confirmed in the adjusted analysis (OR 0.19; 95% CI 0.05, 0.62; p = 0.009) as well as for the other outcomes assessed. CONCLUSION Despite only few sex differences in patient characteristics in nr-axSpA, response rates to TNFi are significantly lower in women than in men.

Abstract
BACKGROUND/OBJECTIVE This study aims to assess the coexistence of fibromyalgia syndrome (FMS) and impact of possible FMS on disease activity in patients with psoriatic arthritis (PsA) and rheumatoid arthritis (RA). METHODS A total of 126 patients, aged 18-65 years old, who were being followed up with PsA (n = 64) and RA (n = 62) diagnoses were included. The Fibromyalgia Rapid Screening Tool (FiRST) was administered for screening FMS. Patients were divided according to the presence of FMS; PsA patients with FMS, patients with PsA without FMS, patients with both RA and FMS and patients with RA without FMS. Disease Activity Score 28 (DAS28) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were recorded. RESULTS FMS was detected in 26.5% of the patients with PsA and 17.7% of the patients with RA (p = .04). A statistically significant higher DAS28 and BASDAI scores were found in patients with FMS (p < .05). There was statistically significant correlation between FiRST with DAS28 and BASDAI scores (p < .001, p = .03, respectively) in PsA patients. No significant correlation was found between FiRST score with age, disease duration, CRP and DAS28 in patients with RA (p > .05). CONCLUSION The patients with concomitant FMS had higher disease activity parameters (DAS28 and BASDAI) than those without FMS.

Abstract
Fibromyalgia (FM) is known a common painful syndrome and its frequency is increased in inflammatory rheumatic diseases. We aimed to assess FM frequency in axial spondyloarthritis (AxSpA) patients and age- and sex-matched healthy controls with the 2011 ACR FM criteria. We evaluated the association between receiving biologic disease-modifying antirheumatoid drugs (bDMARD) and presence of FM. 127 patients with Ax-SpA and 73 age- and sex-matched controls were included. Individuals were assessed according to modified 2011 ACR diagnostic criteria for FM. The pain was evaluated by visual analog scale (VAS). Disease activity was assessed by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Ankylosing Spondylitis Disease Activation Score (ASDAS). Spinal limitation, quality of life, and functionality were assessed. Drug therapies were noted. AxSpA and control group had similar FM rates. 43 (33.9%) patients in AxSpA group and 22 (30.1%) patients in control group had FM diagnosis (p = 0.589). Age, gender, BMI, and CRP values were similar in the AxSpA patients with and without FM, while global VAS and ASDAS scores were higher in patients with FM. Biologic DMARD use was higher in the AxSpA patients with FM; however, the difference was not statistically significant. In conclusion, FM frequency does not increase in AxSpA patients as compared to healthy controls. FM awareness is one of the key points to determine the appropriate treatment due to the influence on disease activity.

Abstract
Comorbid fibromyalgia, in axial spondyloarthritis (axSpA) has been shown to influence disease activity and function, and quality of life. Although several papers exist, there is no comprehensive and robust systematic review to determine the prevalence of fibromyalgia in this patient group. Thus, the aim of the current study was to provide a definitive estimate of prevalence of fibromyalgia in axSpA, and in axSpA sub-classifications. A systematic literature search was conducted in Ovid MEDLINE, EMBASE, Evidence Based Medicine (EBM), and Cochrane Library, updated to April 2020, combining keywords and relevant MeSH headings, to identify papers reporting the prevalence of fibromyalgia in axSpA, or data from which this could be computed. This was then combined in a meta-analysis with data from the Scotland Registry for Ankylosing Spondylitis (SIRAS), a national axSpA register in Scotland. Data was pooled using random or fixed effects models where heterogeneity was greater or lesser than 75%. From 3401 manuscripts initially identified, 15 papers were included in the final review, plus SIRAS, giving data from 16 separate sources. The prevalence of fibromyalgia, among a total of 5214 patients, was 16.4% (95% CI 12.3–20.5%). Prevalence varied with axSpA sub-classification: ankylosing spondylitis: 13.8% (9.1–18.6%); MRI positive non-radiographic axSpA 20.3% (6.5–34.1%); and ‘clinical’ disease: 11.1% (6.0–16.2%). Overall, around 1 in 6 patients with axSpA also meet criteria for fibromyalgia. While estimates from individual studies vary, comorbid fibromyalgia represents a considerable burden across all sub-classifications of axSpA. This emphasises that focusing management solely on inflammatory disease in this patient group is unlikely to yield optimal improvements in quality of life.

Abstract
Fibromyalgia is one of the numerous comorbidities that may accompany inflammatory rheumatic diseases. Concomitant fibromyalgia in inflammatory rheumatic conditions can interfere with symptomatology, disease activity and overall management plan. The aim of the present narrative review article was to discuss the current evidence on (i) the prevalence/frequency of comorbid fibromyalgia in inflammatory rheumatic conditions, (ii) the role of fibromyalgia on disease activity, (iii) the impact of concomitant fibromyalgia on biological disease-modifying antirheumatic treatment outcomes and (iv) potential effectiveness of biological disease-modifying antirheumatic drugs on fibromyalgia-related symptoms among patients with inflammatory rheumatic diseases. A literature search was conducted through PubMed/MEDLINE Cochrane and Web of Science databases by using relevant keywords and their combinations. Studies representing different geographical areas of the world revealed that frequency rates of fibromyalgia are higher in inflammatory rheumatic diseases than those in the general population. Comorbid fibromyalgia interferes not only with the disease activity scores but also with the treatment outcomes and management plan. Further evidence is warranted in order to determine the potential benefits of biological disease-modifying antirheumatic drugs on fibromyalgia-related symptoms in patients with inflammatory rheumatic diseases.

Abstract
OBJECTIVES To examine how comorbidities cluster in axial spondyloarthritis (axSpA) and whether these clusters are associated with quality of life, global health and other outcome measures. METHODS We conducted a cross-sectional study of consecutive patients meeting ASAS criteria for axSpA in Liverpool, UK. Outcome measures included quality of life (EQ5D), global health and disease activity (BASDAI). We used hierarchical cluster analysis to group patients according to 38 pre-specified comorbidities. In multivariable linear models, the associations between distinct comorbidity clusters and each outcome measure were compared, using axSpA patients with no comorbidities as the reference group. Analyses were adjusted for age, gender, symptom duration, BMI, deprivation, NSAID-use and smoking. RESULTS We studied 419 patients (69% male, mean age 46 years). 255 patients (61%) had at least one comorbidity, among whom the median number was 1 (range 1-6). Common comorbidities were hypertension (19%) and depression (16%). Of 15 clusters identified, the most prevalent clusters were hypertension-coronary heart disease and depression-anxiety. Compared with patients with no comorbidities, the fibromyalgia-irritable bowel syndrome cluster was associated with adverse patient-reported outcome measures; these patients reported 1.5-unit poorer global health (95%CI 0.01, 2.9), reduced quality of life (0.25-unit lower EQ5D; 95%CI -0.37, -0.12) and 1.8-unit higher BASDAI (95% CI 0.4, 3.3). Similar effect estimates were found for patients in the depression-anxiety cluster. CONCLUSION Comorbidity is common among axSpA patients. The two most common comorbidities were hypertension and depression. Patients in the depression-anxiety and fibromyalgia-IBS clusters reported poorer health and increased axSpA severity.

Abstract
OBJECTIVE The effects of smoking on disease manifestations in axial SpA are inadequately described. Utilizing a large and well-characterized cohort, we investigated the association between smoking and extra-axial manifestations, and smoking and disease severity measures. METHODS Baseline data from the British Society for Rheumatology Biologics Register for Ankylosing Spondylitis were explored. Our analyses focused on extra-axial manifestations and other disease severity measures, including scales for fatigue, sleep, anxiety and depression. Logistic and linear models were used to quantify associations between disease characteristics according to smoking status (current/ex/never) and quantity (heavy/light), adjusting for age, gender, BMI, education, deprivation, comorbidities, symptom duration and alcohol status. RESULTS A total of 2031 participants were eligible for the current analysis (68% male, mean age 49 years). Of these, 24% were current and 32% ex-smokers. When compared with non-smokers, current smokers had lower odds of uveitis [OR 0.7, 95% CI 0.5-0.9] and higher odds of psoriasis (ORadj 1.6, 95% CI 1.1-2.3). Ex- and current smokers had incrementally more severe disease than never smokers, with higher BASDAI (β = 0.3, 95% CI 0.1-0.6; β = 0.9, 95% CI 0.6-1.2) and BASFI (β = 0.5, 95% CI 0.2-0.8; β = 1.3, 95% CI 1.0-1.6); similar associations were observed for fatigue, sleep, anxiety and depression. CONCLUSION In this large cross-sectional study, we observed that smoking is independently associated with an adverse disease profile in axial SpA, including worse fatigue, sleep, anxiety and depression, and higher odds of psoriasis. The paradoxical association between current smoking and reduced odds of uveitis is interesting and warrants further investigation.

Abstract
Objectives This study aims to determine the incidence of fibromyalgia (FM) in female patients with Behçet's disease (BD) and to investigate whether disease activity changes in the presence of FM in female patients with BD. Patients and methods This cross-sectional study included 72 female patients with BD (mean age 39.7±10.5 years; range, 22 to 74 years) between June 2018 and February 2019. The frequency of FM was evaluated according to the American College of Rheumatology alternative criteria. Active clinical features and BD activity were evaluated with the Behçet's disease activity form (BDCAF). Results The prevalence of FM was 29.2% in the BD patients. BD clinical activity index, patients' perceptions of disease activity and clinicians' overall perceptions of disease activity scores were significantly higher in BD patients with FM (p=0.003, p<0.001 and p=0.025, respectively). The active clinical features of BD were not different between the groups except for genital ulcer. The prevalence of active genital ulcers was higher in BD patients with FM than in BD patients without FM (38.1% vs. 13.7%, respectively). Conclusion Disease activity is higher in female BD patients with FM than those without FM. High disease activity in female BD patients with FM may be associated with the presence of genital ulcers.

Abstract
Non-radiographic axial spondyloarthritis (nr-axSpA) is a recently described form of axial inflammatory arthritis that has not caused substantial erosive damage to the sacroiliac joints. Nr-axSpA is associated with significant impairment in quality of life and, in a proportion of patients, it can evolve into ankylosing spondylitis (AS, also termed radiographic axSpA). The identification in the clinic of nr-axSpA has been made possible by advances in magnetic resonance imaging (MRI). Classification criteria for nr-axSpA have been proposed but there remains discussion in the international community regarding this. Studies are ongoing to further define the classification and diagnosis of nr-axSpA. There is much further research required regarding the optimal use of MRI in nr-axSpA, including distinguishing sacroiliac MRI changes in the normal population and the definition of a positive MRI in spinal disease. Non-steroidal anti-inflammatory drugs and physiotherapy are the core first-line therapy for nr-axSpA. Tumour necrosis factor inhibitors also play a very important role in treatment of patients with active nr-axSpA who do not respond to first-line therapy. Agents directed at interleukin-17, interleukin-23 and Janus kinase inhibitors are proving effective in AS with ongoing and planned studies in nr-axSpA. A great deal of active research is being undertaken in classification, imaging and therapy in nr-axSpA and so the future for improving the lives of patients with nr-axSpA is promising.

Influence of co-morbid fibromyalgia on disease activity measures and response to tumour necrosis factor inhibitors in axial spondyloarthritis: results from a UK national register. Rheumatology (Oxford) 2019; 57:1982-1990. [PMID: 30053166 PMCID: PMC6199528 DOI: 10.1093/rheumatology/key206] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2018] [Indexed: 12/17/2022] Open
Abstract
Objective To quantify the extent to which co-morbid FM is associated with higher disease activity, worse quality of life (QoL) and poorer response to TNF inhibitors (TNFis) in patients with axial SpA. Methods A prospective study recruiting across 83 centres in the UK. Clinical information and patient-reported measures were available, including 2011 criteria for FM. Multivariable linear regression was used to model the effect of meeting the FM criteria on disease activity, QoL and response to TNFis. Results A total of 1757 participants were eligible for analyses, of whom 22.1% met criteria for FM. Those with co-morbid FM criteria had higher disease activity [BASDAI average difference FM+ − FM− 1.04 (95% CI 0.75, 1.33)] and worse QoL [Ankylosing Spondylitis Quality of Life score difference 1.42 (95% CI 0.88, 1.96)] after adjusting for demographic, clinical and lifestyle factors. Among 291 participants who commenced biologic therapy, BASDAI scores in those with co-morbid FM were 2.0 higher at baseline but decreased to 1.1 higher at 12 months. There was no significant difference in the likelihood of meeting Assessment of SpondyloArthritis international Society 20 criteria at 12 months. Less improvement in disease activity and QoL over 3 months of TNFi therapy was most strongly related to high scores on the FM criteria symptom severity scale component. Conclusion Fulfilling criteria for FM has a modest impact on the assessment of axial SpA disease activity and QoL and does not significantly influence response to biologic therapy. Those with a high symptom severity scale on FM assessment may benefit from additional specific management for FM.

AxSpA patients who also meet criteria for fibromyalgia: identifying distinct patient clusters using data from a UK national register (BSRBR-AS). BMC Rheumatol 2019; 3:19. [PMID: 31143851 PMCID: PMC6532149 DOI: 10.1186/s41927-019-0066-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Accepted: 04/25/2019] [Indexed: 12/22/2022] Open
Abstract
Background Around 1 in 8 patients with axial spondyloarthritis (axSpA) also meet criteria for fibromyalgia and such patients have considerable unmet need. Identifying effective therapy is important but to what extent fibromyalgia-like symptoms relate to axSpA disease severity has not been established. The aim of the current analysis was to determine whether distinct clusters of axSpA patients exist and if so to determine a) whether they differ in terms of prevalence of fibromyalgia and b) the features of patients in clusters with high prevalence. Methods The British Society for Rheumatology Biologics Register (BSRBR-AS) recruited axSpA patients from 83 centres 2012-2017. Clinical data, and information from patients was collected (including research criteria for fibromyalgia). Cluster analysis was undertaken using split samples for development and validation both in the whole population and the sub-group which met fibromyalgia criteria. Results One thousand three hundred thirty-eight participants were included of whom 23% met research criteria for fibromyalgia. Four clusters were identified. Two exhibited very high disease activity, one which was primarily axial (n = 347) and a smaller cluster (n = 32) with axial and peripheral disease, and in both groups more than half of members met criteria for fibromyalgia. The remaining two clusters (n = 437, n = 462) had overall less severe disease however the one which showed greater disease activity and poorer quality of life had a higher proportion meeting fibromyalgia criteria (16% v. 4%). Within those meeting fibromyalgia criteria there were three clusters. The two main groups were defined by level of symptom severity with a smaller third cluster noted to have high average swollen and tender joint counts and high levels of comorbidity. Conclusions The major feature defining clusters with a high proportion of persons meeting criteria for fibromyalgia is high axSpA disease activity although clusters with features of fibromyalgia in the absence of high disease activity also show moderately high prevalence. Management may be most successful with pharmacologic therapy to target inflammation but enhanced by the concurrent use of non-pharmacologic therapy in such patients.

Abstract
Introduction We describe the journey to diagnosis of ankylosing spondylitis (AS) from the patient perspective and examine differences in this journey by sex. Methods US adults aged ≥ 18 years with a self-reported AS diagnosis were recruited online through CreakyJoints, a patient support community, and ArthritisPower, a patient research registry. Respondents completed a web-based survey on sociodemographics, disease burden, and diagnosis history. Results were stratified by sex and time to diagnosis using two-sample t tests and χ2 tests, respectively, to observe differences across the groups; P < 0.05 was considered statistically significant. Results Among 235 respondents, 174 (74.0%) were female. Mean (SD) ages of female and male respondents were 48.6 (10.6) and 53.1 (10.3) years, respectively. From the time respondents began seeking medical attention, 87 were diagnosed within ≤ 1 year, 71 in 2–9 years, and 77 after ≥ 10 years. Symptoms that led respondents to seek treatment were back pain (73.2%) and joint pain (63.8%); fatigue and difficulty sleeping were more common among respondents with longer times to diagnosis. During the diagnosis process, men with AS tended to receive quicker AS diagnosis compared with women. Overall, commonly reported initial diagnoses among respondents with longer time to AS diagnosis included back problems and psychosomatic disorders. Significantly more women reported misdiagnoses of fibromyalgia (20.7 vs. 6.6%) and psychosomatic disorders (40.8 vs. 23.0%) compared with men. Conclusions Diagnosis delays and misdiagnoses were common among respondents with AS. Increasing awareness about AS among referring providers may minimize diagnosis delay.

Abstract
OBJECTIVE To investigate the distribution of whole-body magnetic resonance imaging (WB-MRI) inflammatory lesions of peripheral joints and entheses, and their response to adalimumab (ADA) treatment and agreement with clinical measures of disease activity in patients with axial spondyloarthritis (axSpA). METHODS Explorative analysis of an investigator-initiated randomized controlled trial of ADA. WB-MRI was performed at weeks 0, 6, 24, and 48. Detailed analyses of WB-MRI lesions in peripheral joints and entheses were performed, including agreement with clinical measures of disease activity. RESULTS WB-MRI inflammatory lesions were most frequently observed in the acromioclavicular, metatarsophalangeal, and wrist joints (> 10% of joints), and at the greater trochanter, calcaneal insertion of the Achilles tendon, and ischial tuberosity (> 15% of entheses). Inflammation resolved in ≥ 2/3 of involved sternoclavicular, metacarpophalangeal, first carpometacarpal, hip, and tarsometatarsal joints, and pubic symphyses and medial femoral condyles. In contrast, inflammation resolved in ≤ 1/6 of involved acromioclavicular joints, knee joints, and supraspinatus tendon insertions at humerus. Tenderness of joints and entheses agreed poorly with WB-MRI inflammation (κ < 0.40). Joint tenderness resolved more frequently in MRI-positive than MRI-negative joints (8/13, 62% vs 9/34, 26%) after 6 weeks of active treatment. CONCLUSION Inflammatory lesions of peripheral joints and entheses in patients with predominantly axSpA, and changes therein, can be mapped using WB-MRI, and it may contribute to differentiate between inflammatory and noninflammatory joint tenderness.

Abstract
An emerging trend in the medical literature, including the Rheumatology literature, is that of accumulating large, multicentric, multi-national data based on registries of patients seen in real life situations. Such real-world evidence (RWE) may help provide valuable insights into the long-term outcomes of disease in unselected patients seen in daily practice, including patients belonging to vulnerable populations such as extremes of age, during pregnancy and lactation. Evidences gathered from real life practice settings can help understand drug prescription patterns, including adherence to treatment guidelines, cost-effectiveness of therapy, and real-life long-term outcomes, and adverse effects of treatment with particular medications. Registry-based data also helps analyze comorbidities in patients with rheumatic diseases, and their impact on quality of life, morbidity and mortality. Traditionally, a randomized controlled trial (RCT), or systematic reviews of multiple, homogenous RCTs, have been considered the cornerstone of evidence-based medicine, and RWE does, at times, provide differing viewpoints from the results of particular drugs in clinical trial settings. Therefore, in the present day, it is prudent to consider the complementary nature of information derived from RWE to that obtained from rigorous, clinical trial settings. Future guidelines for disease management may consider it relevant to include information from RWE in addition to that available from clinical trials, to help devise management guidelines that are harmonious with routine practice settings.

Uncovering the heterogeneity of disease impact in axial spondyloarthritis: bivariate trajectories of disease activity and quality of life. RMD Open 2018; 4:e000755. [PMID: 30487997 PMCID: PMC6241970 DOI: 10.1136/rmdopen-2018-000755] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Revised: 10/22/2018] [Accepted: 10/23/2018] [Indexed: 12/11/2022] Open
Abstract
Objective The goal of managing axial spondyloarthritis (axSpA) is to improve and maintain patients' health-related quality of life (HRQoL), mainly through targeting towards low disease activity. Here, we aim to gain insight into the joint evolution of HRQoL and disease activity by identifying and characterising latent subgroups of patients with longstanding disease displaying similar trajectories throughout 8 years of follow-up. Methods Data from Outcome in Ankylosing Spondylitis (AS) International Study (n=161) and Groningen Leeuwarden AS cohort (n=264) were used. Biennially, HRQoL was assessed by AS Quality of Life (ASQoL) and disease activity by AS Disease Activity Score-C reactive protein (ASDAS-CRP). Bivariate trajectories of these outcomes were estimated by group-based trajectory modelling. Next, trajectories were profiled by comparing the latent groups with respect to baseline factors using analysis of variance and χ² test. Results Five bivariate trajectories were distinguished, in which ASQoL and ASDAS-CRP were tightly linked: (t1) low impact of disease; (t2) moderate impact; (t3) high impact with major improvement; (t4) high impact with some improvement; (t5) very high impact. Profiling revealed, for example, that (t1) was characterised by male gender and Human Leucocyte Antigen B27 positivity; (t3) by younger age, shorter symptom duration and biological intake and (t5) by the highest proportion of females. Conclusions We identified five bivariate trajectories of HRQoL and disease activity demonstrating a clear mutual relationship. The profiles revealed that both individual-related and disease-related features define the type of disease course in respect to HRQoL and disease activity in axSpA. This may provide clinicians insight into the differences among patients and help in the management of the disease.

The Impact of Fibromyalgia in Spondyloarthritis: From Classification Criteria to Outcome Measures. Front Med (Lausanne) 2018; 5:290.

Abstract
The term spondyloarthritis (SpA) encompasses a broad clinical spectrum characterized by chronic inflammatory conditions affecting the sacroiliac joints, the spine but also peripheral joints and tendons and being additionally associated with the involvement of organs, such as bowel, eye and skin (1). Musculoskeletal pain is a key symptom in SpA. However, although low back pain and/or joint pain are characteristic for SpA, undifferentiated pain at different enthesial sites may also be a concomitant or even the first clinical presentation in some patients (2). In addition, fatigue is another important symptom often reported by patients with SpA, which substantially affects the quality of life (QoL) (3). Fibromyalgia (FM) is the most common diagnosis in patients complaining of chronic diffuse pain with fatigue and may occur alone or in association with chronic inflammatory diseases (4). The prevalence of FM ranges from 2 to 8% in the general population and it can reach up to over 50% in patients with other rheumatic and musculoskeletal diseases (RMDs) (5-7). FM has been identified as the most disabling RMD, based on the patients' perception that their medical condition is not properly recognized (8). This is also due to the poor knowledge about its pathogenesis, and therefore the lack of reliable biomarkers reveals a major unmet need requiring to be addressed in further research studies. Over the last decade, an increasing body of evidence described the impact of FM in SpA highlighting the pitfalls for correct classification, appropriate differential diagnosis and assessment of outcome measures in both conditions. The purpose of this review is to provide an overview of currently available data with regard to the coexistence and reciprocal features of FM and SpA.

Abstract
OBJECTIVE To investigate whether axial spondyloarthritis (axSpA) patients with extremely poor patient-reported outcomes (PROs) at start of first tumour necrosis factor inhibitor (TNFi) treatment have poorer treatment response and shorter treatment retention than other patients. METHOD This observational cohort study was based on the nationwide DANBIO registry. Patients with axSpA who started first TNFi during 2011-2016 were stratified according to baseline Bath Ankylosing Spondylitis Disease Activity Index (BASDAI ≥ 0.0 to ≤ 4.0, > 4.0 to ≤ 5.0, > 5.0 to ≤ 6.0, > 6.0 to ≤ 7.0, > 7.0 to ≤ 8.0, > 8.0 to ≤ 9.0, and > 9.0 to ≤ 10.0). An extremely poor BASDAI was defined as BASDAI > 9.0 to ≤ 10.0. Treatment responses after 6 months [≥ 50% improvement from baseline BASDAI (BASDAI50), ≥ 40% improvement in Assessment of SpondyloArthritis international Society (ASAS40) response, and ASAS partial remission] in patients with extremely poor PROs were compared with other patients by chi-squared tests, and retention rates by log-rank tests. Similar analyses were done for Bath Ankylosing Spondylitis Functional Index (BASFI), pain score, and patient global score. RESULTS The study included 1396 patients (median age 39 years, 60% men). Patients with extremely poor baseline BASDAI [63 patients (5%)] were more often women, ever smokers, and human leucocyte antigen-B27 negative, and had higher body mass index. Response rates were poorer in patients with extremely poor BASDAI vs remaining patients (BASDAI50 19% and 41%, respectively, p < 0.001; ASAS40 16% and 35%, p = 0.002; ASAS partial remission 6% and 22%, p < 0.001). Patients with extremely poor BASDAI had lower 1 year treatment retention (51% and 68%, p < 0.001). Largely similar results were found for patients with extremely poor BASFI, pain score, and patient global score. CONCLUSION Patients who reported an unusually large symptom burden at baseline had poor response rates and low retention rate. In such cases, competing causes of pain should carefully be taken into account when considering treatment with TNFi.

Abstract
Objectives This systematic review and meta-analysis will describe the prevalence of concomitant FM in adults with inflammatory arthritis and quantify the impact of FM on DAS. Methods Cochrane library, MEDLINE, Psychinfo, PubMed, Scopus and Web of Science were searched using key terms and predefined exclusion criteria. As appropriate, proportional and pairwise meta-analysis methods were used to pool results. Results Forty articles were identified. In RA the prevalence of FM ranged from 4.9 to 52.4% (21% pooled). In axSpA the range was 4.11–25.2% (13% pooled in AS only). In PsA the range was 9.6–27.2% (18% pooled). The presence of concomitant FM was related to higher DAS in patients with RA and AS (DAS28 mean difference 1.24, 95% CI: 1.10, 1.37 in RA; BASDAI mean difference 2.22, 95% CI: 1.86, 2.58 in AS). Concomitant FM was also associated with higher DAS in existing PsA studies. Self-reported, rather than objective, components of DAS appear to be raised in the presence of FM (e.g. tender joint count and Visual Analogue Scale (VAS) pain scores). Conclusion FM is common in RA, AxSpA and PsA. Comorbid FM appears to amplify DAS and could therefore influence management of these rheumatic conditions.

Abstract
Background Depression is common among patients with axial spondyloarthritis (axSpA), but reports of its prevalence are highly variable. We performed a systematic review to (i) describe the prevalence of depression in axSpA, (ii) compare its prevalence between axSpA, ankylosing spondylitis (AS) and non-radiographic axSpA (nr-axSpA) cohorts, and (iii) compare disease activity and functional impairment between those with and without depression. Methods We searched Medline, PubMed, Web of Science, PsycINFO, CINAHL Plus, the Cochrane library and conference abstracts of the European League Against Rheumatism, British Society for Rheumatology and American College of Rheumatology using a predefined protocol in accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Meta-analysis was performed using quality-effects model. Results Fifteen original articles and one abstract were included for analysis; 14 studies described AS cohorts and two nr-axSpA. Three screening criteria and one diagnostic criterion were used to define depression. Prevalence ranged from 11 to 64% depending on criteria and thresholds used. Pooled prevalence of at least moderate depression was 15% using the Hospital Anxiety and Depression Scale (HADS) threshold of ≥ 11. The prevalence of depression was similar between axSpA, AS and nr-axSpA cohorts. Patients with depression had significantly worse disease activity, including higher BASDAI by 1.4 units (95% CI 1.0 to 1.9), ASDAS by 0.5 units (95% CI 0.3 to 0.7) and ESR by 3.5 mm/h (95% CI 0.6 to 6.4). They also had greater functional impairment with higher BASFI and BASMI by 1.2 units (95% CI 0.6 to 1.8) and 0.6 units (95% CI 0.3 to 0.8), respectively. Mean age of each study cohort inversely correlated with depression prevalence. Conclusions Depression is common among axSpA patients and is associated with more severe disease activity and functional impairment. Identifying and managing depression should form part of their holistic care. Further longitudinal studies are needed to explore the impact of depression on treatment outcomes and axSpA treatment on symptoms of depression.

Abstract
OBJECTIVE To update French Society for Rheumatology recommendations about the management in clinical practice of patients with spondyloarthritis (SpA). SpA is considered across the range of clinical phenotypes (axial, peripheral, and entheseal) and concomitant manifestations. Psoriatic arthritis is included among the SpA phenotypes. METHODS According to the standard procedure advocated by the EULAR for developing recommendations, we first reviewed the literature published since the previous version of the recommendations issued in June 2013. A task force used the results to develop practice guidelines, which were then revised and graded using AGREE II. RESULTS Four general principles and 15 recommendations were developed. The first four recommendations deal with treatment goals and general considerations (assessment tools and comorbidities). Recommendations 5 and 6 are on non-pharmacological treatments. Recommendation 7 is about nonsteroidal anti-inflammatory drugs, which are the cornerstone of the treatment, and recommendations 8 to 10 are on analgesics, glucocorticoid therapy, and conventional disease-modifying antirheumatic drugs. Biologics are the focus of recommendations 11 through 14, which deal with newly introduced drug classes, including their indications (active disease despite conventional therapy and, for nonradiographic axial SpA, objective evidence of inflammation) and monitoring, and with patient management in the event of treatment failure or disease remission. Finally, recommendation 15 is about surgical treatments. CONCLUSION This update incorporates recent data into a smaller number of more simply formulated recommendations, with the goal of facilitating their use for guiding the management of patients with SpA.

Abstract
Fibromyalgia (FM) is difficult to diagnose and manage chronic pain condition whose symptoms have no clear pathophysiological cause, although it is thought that patient hypersensitivity to a range of stimuli may give rise to mechanical hyperalgesia as a result of altered central nociceptive processing. The 1990 American College of Rheumatology (ACR) classification criteria, which have been widely used in clinical practice, require the existence of chronic widespread pain (CWP) for >3months, and the presence of at least 11 out of 18 specified tender points upon digital palpation, although this latter criterion has long been criticised. The newer 2010 ACR diagnostic criteria state that FM can be defined as CWP associated with somatic symptoms, and recommend the use of a widespread pain index and a scale to rate symptom severity. A modified version of the 2010 criteria removed the physician assessment of the extent of somatic symptoms and replaced it by a summary score of three self-reported symptoms, thus making it easier to use while maintaining its sensitivity. This review discusses the advantages and limitations of all of these criteria.
