Background:The use of bone scintigraphy (Sc) in spondyloarthritis (SpA) as a technique for diagnosis, assessment of activity and treatment decision has been questioned by the scientific community. Due to its low cost compared to Magnetic Resonance Imaging - MRI (the gold standard)1, some studies proposed to evaluate Sc’s diagnostic accuracy. These studies have shown that Sc has a low diagnostic sensitivity of 50-55%2. Also, there is a poor correlation between symptoms and scintigraphic uptake3. We aimed to evaluate the use of Sc for management and follow-up of patients with SpA.Objectives:To determine if Sc activity correlates with patients’ complaints (peripheral and axial), inflammatory markers, disease activity scores and whether it influenced physicians’ treatment decisions during the follow-up of the disease.Methods:We performed a retrospective review of all patients at our department with SpA with at least one Sc from 2018 to 2020. The following variables were analyzed: demographic data, spondyloarthropathy subtype (ankylosing, enteropathic, psoriatic and undifferentiated SpA), axial or peripheral pain, Sc findings (inflammatory vs no-inflammatory activity), inflammatory markers (sedimentation rate - ESR and C-Reactive Protein - CRP), disease activity scores within one year since the Sc (Ankylosing Spondylitis Disease Activity Score with Erythrocyte Sedimentation Rate - ASDAS-ESR and Bath Ankylosing Spondylitis Disease Activity Index - BASDAI) and treatment at the time of the Sc (non-steroidal anti-inflammatory drugs, conventional synthetic disease-modifying antirheumatic drugs (DMARDs), target synthetic DMARDs and biologic DMARD. Treatment decisions (escalation, de-escalation or maintenance) in accordance to Sc results were also reviewed.We used the non-parametric Mann-Whitney’s U test for comparisons between ordinal or numerical variables. For correlations between categorical variables we used the Fisher’s exact test and the χ2-independence test. Tests with p < 0.05 were statistically significant.Results:Fifty-five patients were reviewed, 75% women; median age of 48 years. Seventy-one percent had ankylosing SpA, 15% enteropathic SpA, 5% psoriatic SpA, 5% undifferentiated and 4% reactive SpA. Sixty-two percent of the patients had both axial and peripheral pain and 24% only axial complaints. Sixty-two percent of the patients had a Sc with no inflammatory changes, 27% had peripheral and 25% had axial inflammatory changes; 15% had evidence of both peripheral and axial inflammation. For ankylosing SpA, the median ASDAS-ESR was 2.89 and according to the BASDAI, 66% had active disease. The median CRP and ESR in patients with inflammatory vs a normal Sc was not different (p=0.02 vs p=0.36, respectively). Similarly, Sc findings were not correlated with patients’ axial (p=0.10) or peripheral pain (p=1.0), neither with the ASDAS-ESR (p=0.29) or the BASDAI (p=0.29). There was no correlation between inflammatory activity in Sc and the decision to maintain, escalate or de-escalate treatment (p=0.65), including the decision to start a biological DMARD (p=1.0) or to switch between biological DMARDs (p=0.19).Conclusion:There was no correlation between Sc findings and ESR, patients’ complaints, disease activity or treatment decisions. Considering previous research showing a low diagnostic sensitivity, our findings seem to support a limited role of bone Sc for the follow-up and management of patients with seronegative SpA.References:[1]Khmelinskii N, Regel A, Baraliakos X.

ObjectivesTo investigate the occurrence of sick leave (SL) and the impact of clinical and socioeconomic factors on SL in early axial spondyloarthritis (axSpA).MethodsPatients with a clinical diagnosis of axSpA from the DEvenir des Spondyloarthrites Indifférenciées Récentes (DESIR) cohort with work-related data and up to 5-year follow-up were studied. Incidence, time to first SL and potential role of baseline and time-varying clinical and socioeconomic factors (age, gender, ethnicity, education, job type, marital and parental status) were analysed. Univariable analyses, followed by collinearity and interaction tests, guided subsequent multivariable time-varying Cox survival model building.ResultsIn total, 704 axSpA patients were included (mean (SD) age 33.8 (8.6); 46% men). At baseline, 80% of patients were employed; of these, 5.7% reported being on SL. The incidence of SL among those at risk during the study period (n=620, 88%) was 0.05 (95% CI 0.03 to 0.06) per 1000 days of follow-up. Mean (SD) time to first SL was 806 (595) days (range: 175–2021 days). In multivariable models, male gender (HR 0.41 (95% CI 0.20 to 0.86)) and higher education (HR 0.48 (95% CI 0.24 to 0.95)) were associated with lower hazard of SL, while higher disease activity (HR 1.49 (95% CI 1.04 to 2.13)), older age, smoking and use of tumour necrosis factor inhibitors were associated with higher hazard of SL.ConclusionsIn this early axSpA cohort of young, working-age individuals, male gender and higher education were independently associated with a lower hazard of SL, whereas older age and higher disease activity were associated with higher hazard of SL. The findings suggest a role of socioeconomic factors in adverse work outcomes, alongside active disease.

Background:In the management of chronic arthritis, such as Rheumatoid Arthritis (RA), Ultrasound (US) assessment can provide relevant information about the joint inflammatory status in the diagnostic phase and even more in the monitoring of disease activity and structural damage1,2.Objectives:In this longitudinal study, we aimed to assesse the role of US in predicting the efficacy of JAK-inhibitors (JAKi) in RA patients.Methods:We enrolled RA patients starting baricitinib or tofacitinib. All patients were evaluated at baseline and after 4, 12, 24, 48 weeks. Disease activity was calculated by DAS28CRP. US examination in 22 joints (I–V MCPs and PIPs, wrists) aimed at evaluating inflammatory features (synovial effusion and hypertrophy, power Doppler-PD), through a semi-quantitative scale (0-3). The total US (0-198) and PD (0-66) scores were calculated. We scanned bilateral flexor (I–V fingers of hands) and extensor compartments (1-6) tendons: tenosynovitis was scored as absent/present (0/1), resulting in a total score (0-22).Results:We studied 102 patients (M/F 15/87; median age 59.2 years, IQR 17.75; median disease duration 144 months, IQR 126), 61 treated with baricitinib and 41 with tofacitinib. At baseline, the median total US score was 18 (IQR 19) and the median PD score 2 (4). We observed a significant reduction in both total and PD US scores at all time-points (p<0.0001) (Figure 1). At baseline, 75.4% of patients showed tenosynovitis involving at least one tendon, with a median score of 2 (IQR 3.5) significantly decreasing after 24 weeks (p=0.02). Multivariate analysis, adjusted for baseline DAS28CRP and other concomitant treatments (including glucocorticoids and methotrexate treatment), confirmed the independent association between baseline US (PD and tenosynovitis) scores and the reduction of disease activity at follow-up evaluations.Conclusion:The present study confirmed the early efficacy of JAKi in RA patients by using US evaluation. Furthermore, power doppler and tenosynovitis scores could play a predictive role in response to treatment.References:[1]MUELLER RB, HASLER C, POPP F, et al.

Abstract Background/Aims  Axial spondyloarthritis (axSpA) is a chronic rheumatic condition, characterised by inflammatory back pain - often associated with impaired function and mobility, sleep disturbance, fatigue, and reduced quality of life. Despite the vast advances in pharmacological treatments for axSpA over the last few decades, physical activity and rehabilitation remain vital for effective disease management. At the Royal National Hospital for Rheumatic Diseases in Bath (RNHRD), the 2-week inpatient axSpA rehabilitation programme has been integral to axSpA care since the 1970’s. Prior research has demonstrated significant short-term improvements in spinal mobility (BASMI), function (BASFI) and disease activity (BASDAI) following course attendance. However, the long-term outcomes are yet to be evaluated in this unique cohort. Methods  Since the early 1990’s, clinical measures of spinal mobility, function and disease activity have been routinely collected at the RNHRD at all clinical appointments through administration of the BASMI, BASFI and BASDAI, respectively. Dates of attending the axSpA course and standard clinical and treatment follow-up data were also collected. Multiple linear regression models were used to investigate the impact of course attendance on final reported BASMI, BASDAI and BASFI scores (final score=most recent). Length of follow-up was defined as time between first and last recorded BASMI. Results  Of the 203 patients within the Bath SPARC200 cohort, 77.8% (158/203) had attended at least one rehabilitation course throughout follow-up. 70.0% (140/203) of patients were male. The mean duration of follow-up was 13.5 years (range 0-35 years); 28.1% (57/203) of individuals with 20+ years of follow-up. Course attendance (yes versus no) significantly reduced final BASMI score by 0.84 (p = 0.001, 95%CI -1.31 to -0.37) and final BASDAI score by 0.74 (p = 0.018, 95%CI -1.34 to -0.13). Although course attendance reduced final BASFI by 0.45 (95%CI -1.17 to 0.28), this relationship did not reach significance (p = 0.225). Whilst minimally clinically important difference (MCID) is, to our knowledge, yet to be defined for BASMI, MCIDs were achieved long-term for both BASDAI and BASFI - defined by van der Heijde and colleagues in 2016 as 0.7 and 0.4 for BASDAI and BASFI, respectively. Conclusion  These results provide novel evidence to support the integral role of education, physical activity and rehabilitation in the management of axSpA. Future work should investigate additional outcomes of critical importance to patients and clinicians, such as fatigue, quality of life and work productivity. Furthermore, a greater understanding of the factors that confound these outcomes may provide insights into those patients who may most benefit from attending a 2-week rehabilitation course. In addition to facilitating identification of those patients who may require additional clinical support. Disclosure  R. Barnett: None. A. McGrogan: None. M. Young: None. C. Cavill: None. M.

Background:Standardization of clinical practice has been proven to be effective in management of chronic diseases. This is particularly true at the time where the concept of treat to target is becoming more and more important in the field of axial spondyloarthritis (ax-SpA).Objectives:To propose a list of variables to be collected at the time of the diagnosis and over the follow-up of patients with axial spondyloarthritis (ax-SpA) for an optimal management in daily practice.Methods:The process comprised (1) the evaluation of the interest of 51 variables proposed for the assessment of axSpA via a systematic literature research, (2) a consensus process involving 78 hospital-based or office-based rheumatologists, considering the collection of the variable in a 4 grade scale from ”potentially useful” to “mandatory”, (3) a consensus on optimal timeline for periodic assessment of the selected variables on a 5 grade scale from “at each visit” to “never to be re-collected”.Results:The systematic literature research retrieved a total of 14,133 abstracts, of which 213 were included in the final qualitative synthesis. Concerning the data to be collected at the time of the diagnosis and during follow-up, we proposed to differentiate the results based on a) the way of collection of the variables (e.g. questionnaires by the patient, interview by the physician, physical examination, investigations) b) the usefulness these variables in daily practice based on the opinion of the rheumatologists ” c) the optimal timeline between 2 evaluations of the variable based on the opinion of the rheumatologists. In the initial systematic review, symptoms of heart failure history of inflammatory bowel disease, psoriasis or uveitis, patient global visual analogic scale, spine radiographs, modified Schöber test, coxo-femoral rotations, swollen joint count, urine strip test, BASDAI and ASDAS global scores were considered very useful and nocturnal back pain/morning stiffness, sacro-iliac joints radiographs and CRP were considered mandatory (Figure 1). Timeline between 2 evaluations of variables to collect in the periodic review are summarized inFigure 2.Figure 1.Core sets of items to collect and report in the systematic review in axial spondyloarthritis management in daily practice ASDAS=Ankylosing Spondylitis Disease Activity Score, BASDAI=Bath Ankylosing Spondylitis Disease Activity Index, BASFI=Bath Ankylosing Spondylitis Functionnal Index, BASMI=Bath Ankylosing Spondylitis Metrology Index, CRP=C Reactive Protein, CT=computerized tomography, FIRST=Fibromyalgia Rapid Screening Tool, HLA=Human Leukocyte Antigen, MRI=Magnetic resonance imaging, PET=positron emission tomography.Figure 2.Periodic review timeline of variables to collectASDAS=Ankylosing Spondylitis Disease Activity Score, BASDAI=Bath Ankylosing Spondylitis Disease Activity Index, Spondylitis Metrology Index, CRP=C Reactive Protein, IBD = inflammatory bowel diseases, PRO = Patient Reported OutcomesConclusion:Using an evidence-based and an expert consensus approaches, this initiative defined a core set of variables to be collected and reported at the time of the diagnosis and during follow-up of patients with ax-SpA in daily practice.Acknowledgments:this study has been conducted in two parts: the first one (evidence-based) was conducted thanks to a support from Abbvie France.

Sarcoidosis is a systemic inflammatory disorder characterized by “noncaseating granulomas.” It primarily affects the lungs, but multiple other organs can be involved. Sarcoidosis has been increasingly reported in association with cancer. It can precede, follow or occur at the same time as the diagnosis of cancer. We report a case of sarcoidosis that was diagnosed concomitantly with colon cancer, highlighting the diagnostic dilemma of sarcoidosis vs. cancer metastasis, the relationship between the two, and the value of PET scan in follow-up and monitoring of disease activity.

Abstract Background The objective of this study is to assess the degree of parietal involvement with ultrasound and see how they influence the prognosis according to the findings. Methods It was defined as ‘parietal healing’ the normalisation of ultrasound findings in a previously affected segment (parietal thickness less than 3 mm and absence of parietal hyperaemia). Therefore, patients with absence of ultrasound activity but without reaching parietal healing were considered to be those without significant inflammatory signs (parietal thickness &lt;4.5 mm and absence of hyperaemia or other inflammatory data) but who had not ‘normalised’ the previously affected segment. Results A total of 111 patients without ultrasound inflammatory activity were included. It was studied whether normalisation of parameters in a previously affected segment, i.e. parietal healing gave a better prognosis during follow-up. It was detected that 74 patients achieved ‘parietal healing’ and this subgroup of patients generally had a flare in 12% of cases (9/74 patients) compared with 27% of cases (10/37) among patients without parietal healing, these differences were statistically significant (p = 0.05). Similar, it was identified that among patients without ultrasound activity who had a subsequent outbreak during follow-up, the median survival was lower (1,09 years) in patients without parietal healing vs. those with parietal healing (1.4 years), the differences reaching statistical significance (p = 0.03). Likewise, during the follow-up, it was objectived, by means of survival analysis, that the evolution of patients without ultrasound activity was more favourable in those with ‘parietal healing’ with remission 95% vs. 90% at first year, 89% vs. 81% at 2 years and 85% vs. 66% at 3 years of follow-up. The results are outlined in Figure 1. Conclusion To conclude, detecting parietal healing by ultrasound improves prognosis by decreasing the number of outbreaks and increasing the median survival until outbreaks occur.

Objective: to compare the impact of continuous or on-demand use of nonsteroidal anti-inflammatory drugs (NSAIDs) on the activity and radiographic progression of early axial spondyloarthritis (axSpA).Subjects and methods. The investigation enrolled patients from the early spondyloarthritis cohort who met the 2009 Assessment of Spondyloarthritis International Society (ASAS) criteria for axSpA. This analysis included 68 patients who had been followed up for at least 24 months. The mean age at the time of inclusion in the investigation was 28.5±5.8 years; the mean disease duration was 24.1±15.4 months; 63 (92.6%) patients were HLA-B27-positive. The patients were divided into two groups: 1) 35 patients used NSAIDs at maximum therapeutic doses continuously during the follow-up period; 2) 33 patients received these drugs on-demand, depending on the presence and severity of back pain.Results and discussion. After 2-year follow-up, the median stage of radiographic sacroiliitis (SI) in Group 1 was unchanged and remained equal to 4; that in Group 2 in this period significantly increased from 3 to 4 scores (p < 0.05). At baseline, the patient groups did not differ in C-reactive protein (CRP) levels, the Ankylosing Spondylitis Disease Activity Score (ASDAS-CRP), and the Bath Ankylosing Spondylitis Functional Index (BASFI); however, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) was higher in Group 1 (p < 0.05). The number of patients with active SI, as evidenced by magnetic resonance imaging (MRI), and the degree of its severity did not differ significantly between groups. After 2 years, all the patients retained low disease activity according to ASDAS-CRP, BASDAI, and CRP levels; and these measures did not differ significantly between groups either; the BASFI became higher in Group 1. MRI findings indicated that the number of patients with active SI decreased, but no differences were found between the groups.Conclusion. In patients with early axSpA, the continuous intake of NSAIDs can slow radiographic progression to a greater extent than their on-demand use.

The evolution of axial spondyloarthritis (axSpA) and the transition of its nonradiographic to radiographic stage, when ankylosing spondylitis (AS) can be diagnosed, concern many researchers. To clarify this issue, an active search for predictors of the progression of this disease is underway; special cohort studies are being conducted.Objective: to analyze two-year changes in the magnetic resonance imaging (MRI) signs of sacroiliac joint (SIJ) inflammation and disease activity in patients with axSpA who form a Moscow CoRSAr cohort (a Cohort of early SpondylArthritis) and the role of these indicators in the progression of sacroiliitis.Subjects and methods. The investigation enrolled 68 CoRSAr cohort patients followed up for two years. All the patients underwent pelvic radiography and SIJ MRI at inclusion in the cohort and then every year. At inclusion in the cohort, nonradiographic axSpA was present in 28 patients, and AS was in 40. Disease activity was determined by BASDAI and ASDAS-CRP. The progression of sacroiliitis was assessed by the total scores of radiographic sacroiliitis.Results and discussion. The patients' age at inclusion in the cohort averaged 28.5±5.8 years, with a mean disease duration of 24.1±15.4 months and a male proportion of 51.5%; the HLA-B27-positive patients were 92.6%. At two years, 39% of the patients with nonradiographic axSpA went to the AS group. 24-month sacroiliitis progression was observed in 40% of the patients. Disease activity had little impact on the progression of sacroiliitis.Conclusion. Over two years, almost 40% of patients with axSpA showed an increase in the radiographic stage of sacroiliitis in the CoRSar cohort; this progression was primarily associated with the foci of osteitis according to MRI and correlated little with the activity of the disease.

Abstract Objectives The aim of the study was to assess the role of MR Enterography (MRE) in the diagnosis and follow-up of children with Crohn’s disease (CD) and to correlate disease activity indices with known MRE features of active disease. Methods This was a retrospective study including 24 patients (median age 11 years, 17 males) with clinically and histologically proven CD who underwent MRE. Two previously validated MRE scores—Magnetic Resonance Enterography Global Score (MEGS) and CD MRI index (CDMI)—were calculated. A correlative analysis was made between the Pediatric Crohn’s Disease Activity Index (PCDAI) score and MRE scores as well as individually with each MR variable. Comparison of both the MR scores was made between patients with different disease activity. Results MEGS and PCDAI scores showed strong positive correlation (r = 0.724, p = < 0.001); CDMI and PCDAI scores showed moderate positive correlation (r = 0.661, p = 0.0004). There was statistically significant difference in the MR scores between patients grouped by clinical activity. Among individual MR variables, mural thickness and enhancement best predicted the disease activity. Conclusions MRE-based scores and findings correlate with clinical activity in pediatric CD. Thereby, MRE can be considered a valuable tool in the management of CD, predicting disease activity and offering a potential alternative to endoscopy in monitoring patients during follow-up.
