Home exercise is considered essential, but patient compliance remains a mystery

BackgroundRegular exercise is essential in the treatment of Ankylosing Spondylitis (AS), as the main goals of the treatment are to reduce pain, restore function, avoid disability and structural deterioration, and improve quality of life (QoL). The purpose of this study is to ascertain whether patients adhere to exercise recommendations and to evaluate the effects of consistent exercise on patients' pain, function, disease activity, mood, and quality of life. Many studies emphasize the need for exercise in treatment of AS, but none reveal whether patients follow prescribed practices and the results of doing so.ResultsExercising group had significantly decreased pain, erythrocyte sedimentation rate and Bath ankylosing spondylitis functional index and Bath ankylosing spondylitis disease activity index (BASDAI) scores (p < 0.05). There was no significant difference between the two groups in morning stiffness, mood, spinal mobility, and QoL parameters (p > 0.05). Regular exercise was positively correlated with physiotherapy history. Regression analysis revealed that with an increase of 1 unit in visual analog scale and BASDAI, regular exercise decreased by 0.087 and 0.116 units, respectively.ConclusionOur study revealed how much the patients considers and follows the recommended exercises and concluded that regular exercise habits should be developed since they offer promising effects in treatment of AS, hence, patients should be educated in this area, and particular exercise routines should be developed to encourage them to exercise.

The Effect of Obesity in Individuals with Ankylosing Spondylitis: A Single Center Cohort Study

Aim: The aim of this study was to compare the disease activity and functional status of individuals with Ankylosing Spondylitis (AS) according to body mass index (BMI). Material and Methods: This study, which was planned as a single-center cohort study, included 437 individuals with AS. Disease activities were evaluated with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and functional levels with the Bath Ankylosing Spondylitis Functional Index (BASFI). Participants were categorized in 3 groups according to BMI data based on the criteria of the World Health Organization: normal weight:20-24.9; overweight: 25-29.9; obese:≥30. One Way Anova Test, Kruskal Wallis Test, Mann Whitney U test and Chi-Square Test were used to compare independent group differences. Linear regression models were used to describe the relationship between BASDAI, BASFI (dependent variables) and BMI categories (independent variables). Univariate regression analyses were performed (only one independent variable in the model). Results: Among 437 patients with AS, 30.2% are normal weight, 39.5% are overweight and 30.2% are obese. Analysis results of data between BMI groups; significant difference was in BASFI (p=0.001) in favor of the obese group. In binary group comparisons for BASFI; there was a significant difference in favor of the obese group between normal and obese (p=0.002) and between overweight and obese (p=0.001). Obese was significantly associated with higher BASFI score compared to the normal weight group without adjustment for covariates (β:-0.37, 95%CI -0.66/-0.08, p=0.006). On the other hand, there was no association between BASDAI and obesity (β:-0.50, 95%CI -1.11/ 1.22, p:0.130). Conclusion: The BMI of Turkish AS individuals in a single center cohort had no effect on disease activity, but obesity had a worse effect on functional level.

Comparative characteristics of axial spondyloarthritis and psoriatic arthritis with axial involvement

Objective – to compare clinical characteristics of patients with axial spondyloarthritis (axSpA)/ankylosing spondylitis (AS) and with axial psoriatic arthritis (axPsA).Subjects and methods. 100 patients were examined: 45 – with axSpA/AS (group 1), 55 – with axPsA (group 2). Patients of group 1 were included according to axSpA/AS criteria, patients of group 2 – according to CASPAR (ClASsification criteria for Psoriatic ARthritis) criteria, and having axial involvement (axPsA). Axial involvement was detected in case of radiologically significant sacroiliitis (bilateral grade ≥2 or unilateral grade ≥3) or active MRI sacroiliitis, or ≥1 syndesmophyte(s) of the cervical and/or lumbar spine. Patients were evaluated for presence of inflammatory back pain (IBP) by ASAS (Assessment of Spondyloarthritis International Society) criteria.Results and discussion. Patients of group 1 were younger (p&lt;0.001), more often HLA-B27 positive (p&lt;0.001), had more IBP (p=0.001). Patients of group 2 had older age (&gt;40 years) at back pain onset (p&lt;0.001), more often peripheral arthritis (p&lt;0.001), dactylitis (p=0.004), and skin psoriasis (p&lt;0.001). Nail psoriasis was found only in group 2 patients (p&lt;0.001). Group 1 patients had more often heel enthesitis (p=0.005). Group 2 patients had worse axial disease activity scores: BASDAI (Bath Ankylosing Spondylitis Disease Activity Index; p=0.006) and ASDAS-СRP (Ankylosing Spondylitis Disease Activity Score with C-reactive protein level determination; р&lt;0.001); and worse patient reported outcomes: BASFI (Bath Ankylosing Spondylitis Functional Index; p=0.004), patients’ pain (p=0.005) and patients’ global assessments (p=0.036). Patients of group 2 had more syndesmophytes of the lumbar (р=0.009) and cervical (р=0.007) spine. Only in group 2 patients, chunky “non-marginal” syndesmophytes were found (in 32.1%), as well as spinal lesions without sacroiliitis (in 20.0%). Patients of group 2 had more joint erosions (р=0.001), osteolysis (р=0.015), juxta-articular bone formation (р&lt;0.001) and joint ankyloses (р=0.02). All patients of group 1 and only 80% of group 2 (р=0.003) met ASAS criteria for axSpA. AxSpA/AS and axPsA seem to be two different diseases. In our cohort of patients, axPsA patients had worse disease status compared to axSp and AS.

[Clinical value of high frequency ultrasound in the diagnosis of hip joint involvement in patients with ankylosing spondylitis].

To analyze the correlation between hip joint musculoskeletal ultrasound score and ankylosing spondylitis (AS) disease activity, as well as to investigate the value of high frequency ultrasound in the assessment of hip joint involvement in AS. The clinical data of 244 patients with AS who were treated in the rheumatology department of from March 2019 to March 2022 were retrospectively analyzed. Among them, there 174 males and 70 females, aged from 19 to 58 years old with an average of (34.22±9.49) years old;the disease duration of AS patients ranged from 8 months to 26 years, with an average of (13.68±4.04) years.The 244 patients were divided into disease group (83 cases) and control group (161 cases) based in the presence of hip joint involuement. According to the the disease activity, patients in the disease group were further categorezed into active phase (45 cases) and stable phase (38 cases). The ultrasound scores of patients in the active and stable phases of the disease group and the control group were compared. Relevant factors of hip joint involvement in AS patients were analyzed, and analyze the correlation between ultrasound score and Bath ankylosing spondylitis disease activity score index(BASDAI), Bath ankylosing spondylitis functional index(BASFI), visual analogue score of pain (VAS), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and the correlation between hip joint capsule score and tendon attachment end score and BASDAI, BASFI, VAS, CRP and ESR. The hip joint capsule score(3.06±1.12), femoral head score(1.45±0.43), tendon attachment end score(3.28±1.30) and total ultrasound score(6.65±2.31) of the disease group were higher than those of the control group(1.51±0.48)、(0.66±0.27)、(1.61±0.53)、(3.81±1.44)scores (P<0.05). Multifactor Logstic regression analysis showed that the course of disease, hip joint capsule score and total ultrasound score were independent risk factors for hip involvement in AS patients.The hip capsule score (3.65±1.22)and total ultrasound score(8.28±2.33) in the active phase of the disease group were higher than those in the stable phase (2.48±1.04)、( 6.82±1.96)scores(P<0.05). The hip joint capsule score and total ultrasonic score of AS patients were positively correlated with BASDAI, BASFI, VAS, CRP, and ESR (P<0.05, P<0.01).The score of tendon attachment end was positively correlated with CRP (P<0.05). The score of joint capsule effusion in AS patients was positively correlated with BASDAI, BASFI and VAS (P<0.05, P<0.01). The synovial blood flow score was positively correlated with BASDAI, VAS, CRP and ESR (P<0.05, P<0.01). The synovial thickening score was positively correlated with BASDAI, BASFI, VAS, CRP and ESR (P<0.05, P<0.01). There was no correlation between the score of tendon attachment end and BASDAI, BASFI, VAS, CRP and ESR. There is a correlation between hip joint ultrasonic score of hip joint and clinical indexes in AS patients.Hip joint capsule score and total ultrasonic score were independent risk factors for hip involvement in AS patients. High frequency ultrasound exhibits clinical value in the diagnosis of hip joint involvement in AS patients.

E074 Clinical features, disease activity and functional outcome of juvenile-onset, adult-onset and late-onset ankylosing spondylitis: a cross sectional study from India

Abstract Background/Aims Ankylosing spondylitis (AS) or radiographic axial spondyloarthritis (axial SpA) is reported to present with peripheral arthritis, less spinal symptoms, and more radiographic damage in juvenile onset (age at onset ≤16 years) as compared to adult-onset AS(age at onset &amp;lt;45 years). Functional outcome has varied depending on the population studied. In this cross-sectional study we compared clinical features, disease activity, and functional outcome among juvenile-onset AS (JoAS), adult-onset AS(AoAS), late-onset AS (LoAS). Methods Consenting patients fulfilling either the ASAS classification for axial SpA or 1984 modified New York criteria attending SpA clinic were included between May and June 2022. Data was collected by direct patient interview and clinical examination. Data collected: Clinical features, treatment, current disease activity by Bath AS disease activity index (BASDAI), current functional outcome by the Bath Ankylosing Spondylitis Functional Index (BASFI). Disease activity, functional outcome were compared among JoAS, AoAS, and LoAS. Study protocol was approved by the IEC. Results Of 73 patients (61 male), mean age 39.1±12.8 years, 10 (13.7%) were JoAS, 56 (76.7%) and 7 (9.6%) were AoAS and LoAS respectively. Only 30%, 59%, and 57% patients in JoAS, AoAS, and LoAS respectively were employed. There were no differences in the clinical presentation, namely back pain, neck pain, hip involvement, uveitis, and enthesitis among the three groups (Table 1). Majority received conventional-synthetic-DMARDs; only 2(20)%, 8(14.3), and 1(14.3) in the JoAS, AoAS, and LoAS group respectively had ever received TNF-inhibitors. Majority patients in all the groups had active disease (BASDAI&amp;gt;4 and ASDAS&amp;gt;1.3) and there was also no difference in the disease activity (at enrolment) between the groups. All patients with JoAS were positive for HLA-B27. Mean BASFI was not different between the groups, but poor functional outcome (BASFI &amp;gt;6) was observed in 5/10 (50%), 28/56 (50%), 5/9 (71.4%) patients of JoAS, AoAS, and LoAS respectively. Conclusion In a study involving a homogeneous cohort of Indian AS, there were no marked differences in clinical features, disease activity between JoAS, AoAS, and LoAS. Majority patients have poor functional outcomes which could be a direct effect of poor disease control due to lack of access to TNF inhibitors. Disclosure K. Modadugu: None. M.M. Thabah: None.

P168 The impact of psoriatic arthritis on quality of life and lifestyle: a systematic review

Abstract Background/Aims Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects adults of all ages. It is common for patients to experience a wide variety of physical and psychological problems. The objective of this systematic review was to determine how PsA impacts a person's quality of life (QoL). Methods A systematic literature search of CENTRAL, CINAHL, AMED, EMBASE, Global Health, MEDLINE and PsycINFO databases was conducted on 28th May 2021. Title, abstract and whole text screening, and data extraction were completed by two independent authors. The primary outcomes of this study were PsA activity and severity, impact of PsA on lifestyle and QoL. As per the protocol (PROSPERO CRD42021257395), studies which reported at least one of these primary outcomes were included. The quality assessment was conducted using the Joanna Briggs Institute Critical Appraisal criteria. Results Of the 20,316 papers identified by the search strategy, 42 papers which reported on at least one of the study primary outcomes were included in the review. 38 studies reported on PsA activity and severity, 26 on impact of PsA on lifestyle and 23 on QoL. 7 different measures were used to assess impact of PsA on lifestyle, including Health Assessment Questionnaire (HAQ) (n = 13), modified HAQs (n = 10), PsA impact of disease measure (n = 2), functional capacity ACR (n = 1), functional assessment of chronic illness therapy (n = 1), Bath ankylosing spondylitis functional index (n = 1) and a patient-directed question (n = 1). 13 papers reported an average HAQ score between 0.13 and 1.3 for PsA participants. Two studies which reported HAQ disability index compared PsA participants to other groups. Thus, the impact of disease on lifestyle is worse for PsA compared to psoriasis, rheumatoid arthritis and healthy controls, psoriasis. DAPSA and PASI were the most used disease activity scores in addition to various patient-reported outcomes. The average DAPSA was 15.5, suggesting that the majority of PsA patients have moderate disease activity. Although the average PASI (skin) score showed mild disease among the PsA (3.82) group, a high PASI score was associated with late/never minimal disease activity and obesity. 8 different measures were used to assess QoL, including Psoriatic Arthritis Quality of Life (n = 6, average), EQ-5D (n = 4), EQ-3D (n = 1), DLQI (n = 7), SF-36 (n = 3), SF-12 (n = 1), WHOQOL-BREF (n = 2), PSQI (n = 1), Rosenberg Self-Esteem Scale (n = 1) and Psoriasis disability index (n = 1). Except for QoL for skin (DLQI), PsA was associated with worse outcomes in all these measures, in comparison with spondylarthritis, healthy control and psoriasis only groups. Conclusion PsA significantly affects a patient's life and health-related QoL. The degree of activity and severity of the disease have a substantial impact. Therefore, for patients with high disease activity, specific management plans should be discussed and facilitated to maintain their mobility and functional abilities. Disclosure L. James: None. R.

Effectiveness of risankizumab for the treatment of psoriatic arthritis: a multicenter, real-world study.

IL-23 inhibitors were recently approved for the treatment of skin psoriasis and psoriatic arthritis (PsA). Risankizumab, a humanized monoclonal antibody that specifically binds the p19 subunit of IL-23, has proven effective on PsA in two randomized controlled trials. To date, only a few real-world data are available on this topic. Our study aimed to prospectively evaluate the effectiveness of risankizumab in patients with PsA in a real-world setting. For this purpose, both rheumatologic and dermatologic assessments were performed at baseline and after 28-40 weeks of continuous risankizumab administration. Moreover, joint and entheses ultrasound assessment was performed at the mentioned time points. The rheumatologic assessment was carried out by means of the following scores: (i) clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA); (ii) Leeds Enthesitis Index (LEI); (iii) Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and (iii) Bath Ankylosing Spondylitis Functional Index (BASFI). The degree of skin involvement was measured by both the Psoriasis Area and Severity Index (PASI) and Physician Global Assessment (PGA). Quality of life was assessed by the Health Assessment Questionnaire (HAQ) and Dermatology Life Quality Index (DLQI). Ultrasound assessment of joints and entheses was performed on the basis of the EULAR-OMERACT score. After treatment, cDAPSA decreased from a mean value of 12.9 ± 7.6 to 7.0 ± 6.1 (P < 0.001), and the median PD score significantly decreased from baseline (3; range 1-8) to TP1 (1; range 0-7) (P < 0.001). PASI score also decreased from 8.4 ± 4.9 to 0.3 ± 0.5 (P < 0.001), and PGA from 3.1 ± 1.0 to 0.4 ± 0.5 (P < 0.001). We can conclude that risankizumab led to substantial improvement in both skin and joint involvement.

TREATMENT, DISEASE CONTROL, QUALITY OF LIFE AND PSYCHOLOGICAL STATUS IN PATIENTS WITH ANKYLOSING SPONDYLITIS DURING THE COVID-19 PANDEMIC

Introduction. The coronavirus disease (COVID-19) pandemic has the potential to impact disease activity and psychological well-being in people with rheumatic diseases. This study aimed to compare ankylosing spondylitis (AS) patients with and without COVID-19 history in terms of treatment, disease control, quality of life and psychological status by providing a cross-sectional look at treatment, disease control, quality of life and psychological status in patients with AS during the COVID-19 pandemic.&#x0D; Methods. The study included 74 AS patients, in two groups based on COVID-19 history. Demographic data and clinical characteristics were recorded. Treatment, disease control, functional status, and quality of life were evaluated using Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Functional Index (BASFI), and impact of COVID-19 on quality-of-life scales. Psychological status was assessed using the Beck Depression Inventory, Beck Hopelessness Scale, and COVID-19 anxiety scale.&#x0D; Results. Of the 74 patients diagnosed with AS, 44 were female and 34 were male. The mean age was 47.3 years. In total, 35 patients (47.3%) had COVID-19. We found that the group without COVID-19 had significantly higher levels of hypothyroidism than the other group (p = 0.008). The BASFI value was significantly higher in the COVID-19 group (p = 0.031). The group with COVID-19 had a substantially higher rate of continuing non-anti-rheumatic drug use than the other group (p = 0.02).&#x0D; Conclusion. During COVID-19 pandemic period, the majority of patients continued their medication, so treatment and disease control were not negatively affected. Having COVID-19 did not cause a significant difference psychologically.

The thiol/disulfide balance is shifted towards oxidation in psoriatic arthritis compared to controls and is associated with higher disease activity.

This study was designed to compare thiol/disulfide and ischemia-modified albumin (IMA) levels between psoriatic arthritis (PsA) and healthy controls and evaluate the correlation between these molecules and the disease activity scores used in PsA. A total of 63 PsA patients and 49 healthy volunteers were included in the study. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), modified disease activity score 28 (DAS28), and Bath Ankylosing Spondylitis Functional Index (BASFI) scores were used as disease activity indices for PsA patients. Calculations of native thiol (-SH), disulfide (-SS), and total thiol (-SH+-SS) molecules were made by the automatic spectrophotometric method, and the albumin cobalt binding test was used to measure IMA levels. In the PsA group, -SS/-SH and -SS/(-SH+-SS) levels were higher and -SH/(-SH+-SS) levels were lower than in controls. In the linear regression analysis, a significant correlation relationship was detected between DAS28-erythrocyte sedimentation rate (ESR) and -SS/(-SH+-SS) (β = 0.795, CI 95%, 0.196-1.395; P = .010), -SH/(-SH+-SS) (β = -0.475, CI 95%, 0.114-0.836; P = .010) and IMA (β = 3.932, CI 95%, 0.859-7.005; P = .013). Additionally, a significant correlation was detected between IMA and BASDAI and BASFI. In PsA, thiol/disulfide homeostasis has shifted in favor of disulfide as an oxidative indicator. Serum thiol/disulfide levels are correlated with PsA disease activity indices.

Navigating the Factors Affecting Functional impairment in Spondyloarthritis

Objectives: To assess the predictive factors of functional impairment in SpA patients assessed with BASFI (Bath Ankylosing Spondylitis Functional Index) and LI (Lequesne Index). Methods: We conducted a retrospective study that included SpA patients. Socio-demographics and disease-related data were reported (data collection spread over four months from August 2019 to November 2019). Disease activity was assessed using the Bath Ankylosing Spondylitis-Global score (BASG-s) and the Bath Ankylosing Spondylitis disease activity Index (BASDAI). The spinal mobility was evaluated by The Bath Ankylosing Spondylitis Metrology Index (BASMI). Structural progression was evaluated with The Bath Ankylosing Spondylitis Radiologic Index (BASRI) and modified Stoke ankylosing spondylitis spine score (mSASSS). We conducted a multivariate analysis to search for predictive factors associated with BASFI and LI. Significance was accepted for a p &lt; 0.05 for all statistical tests. Results: Two hundred and sixty-three patients were included. Mean age of the patients was 38.9 ±12.7 years, sex-ratio=2.7. Mean age of onset of SpA was 27.6 ± 10.8. Disease duration was 11.3 ±9.5 years. Occupation was significantly associated with BASFI score and LI. A significant functional impact was significantly correlated with a long duration of the disease. The two scores were correlated with a limitation of spinal mobility (BASMI), a greater disease activity (BASDAI and ESR) and a greater impact of the disease on health status (BASG-s). Significant functional impairment was also correlated with structural impairment: mSASSS, BASRI and sacroiliitis grade. The variables independently related to BASFI were the mSASSS score and the BASDAI. The variables independently related to LI were the profession (unemployed subjects had higher scores), mSASSS score, and the BASMI. Conclusion: Occupation, disease activity, mobility and structural progression predicted functional impairment in Tunisian SpA patients.&#x0D; Keywords: Spondyloarthritis; North Africa; Function; Impairment.

Can serum granulocyte-macrophage colony-stimulating factor and CCL17 levels be a marker of disease activation in spondyloarthritis?

Objectives: The aim of this cross-sectional study was to investigate if serum levels of granulocytemacrophage colony-stimulating factor (GM-CSF) and CC chemokine ligand 17 (CCL17) correlate with disease activity in axial spondyloarthritis (axSpA) and peripheral spondyloarthritis (pSpA) patients. Patients and methods: The cross-sectional study was conducted with 80 individuals (48 females, 32 males; mean age: 47.7±11.5) between March 2021 and September 2021. Of the participants, 20 were axSpA, 20 were pSpA, and 20 were active rheumatoid arthritis patients, and the remaining 20 were healthy controls. Age, sex, body mass index, disease duration, comorbid diseases, smoking status, medical treatments, C-reactive protein (CRP) level and human leukocyte antigen B27 (HLA-B27) positivity were recorded. Serum GM-CSF and CCL17 levels were analyzed by ELISA. Ankylosing Spondylitis Disease Activity Score with CRP (ASDAS-CRP) was used to evaluate the disease activity of patients with spondyloarthritis. Functional status of spondyloarthritis patients was evaluated by Bath Ankylosing Spondylitis Functional Index (BASFI). Results: While the serum GM-CSF levels were similar in the axSpA and pSpA groups, they were significantly higher than the healthy control group (p=0.021 and p=0.009, respectively). There was a significant correlation between GM-CSF levels and ASDAS-CRP (r=0.545, p=0.013) and BASFI (r=0.546, p=0.013) in the axSpA group. In active axSpA patients, the cut-off value for GM-CSF was 15.89 pg/mL (sensitivity 50%, specificity 100%). No differences were detected in serum CCL17 levels among the groups. Conclusion: The results suggest that serum GM-CSF levels may be used as a new marker for the evaluation of disease activity in axSpA, and GM-CSF might be a therapeutic target.

The relationship between clinical parameters and ultrasonographic enthesitis assessment in patients with spondyloarthritis

Objectives: The study aimed to evaluate the role of ultrasonographic assessment of enthesitis in patients with spondyloarthritis (SpA) in terms of disease activity, functionality, and quality of life. Patients and methods: Ninety SpA patients (57 males, 33 females; mean age: 37.5±9.7 years; range, 18 to 60 years) were included in cross-sectional study between November 2016 and January 2017. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Ankylosing Spondylitis Disease Activity Score (ASDAS), Bath Ankylosing Spondylitis Functional Index (BASFI), Short Form-12 (SF-12), and Ankylosing Spondylitis Quality of Life (ASQoL) were utilized for clinical evaluation. The clinical evaluation of enthesitis was performed with the Spondyloarthritis Research Consortium of Canada (SPARCC) and Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) via an algometer calibrated to 4 kg/cm2 of pressure. Ultrasound evaluation was performed according to Madrid Sonographic Enthesitis Index (MASEI). A total of 2,610 entheseal sites were examined clinically, and 1,080 were assessed ultrasonographically. Results: A significant proportion of enthesitis (463/1,080) was detected on ultrasonographic evaluation but not with clinical enthesitis score (MASES and SPARCC). Although ultrasonographic entheseal evaluation detected enthesitis in at least one enthesis of all patients, 35 of the patients had no enthesitis with clinical examination. The sites most frequently involved in the entheses were the proximal patellar tendon and Achilles tendon. The MASEI score did not correlate with the MASES, SPARCC, BASDAI, SF-12, and ASQoL but moderately correlated with the C-reactive protein (CRP) level (r=0.348), ASDAS-CRP (r=0.294), and BASFI score (r=0.244). Conclusion: The association of ultrasonography scores with CRP levels and ASDAS-CRP indicates that ultrasonography is effective in detecting inflammation. The MASEI score weakly correlates with functionality but not with quality of life. Ultrasonographic evaluation is invaluable and merits to be incorporated into SpA disease scoring system.

The state of bone mineral density in men with ankylosing spondylitis and its relationship with the course of the disease.

The aim of the study was to study the structural and functional state of bone tissue in men with ankylosing spondylitis (AS) and to assess its relationship with the course of the disease. A study was conducted with the participation of 105 men with AS aged from 22 to 59 years (average age was 40.7 ±0.8 years) with a duration of the disease of 8.7 ±0.5 years and 29 persons of the control group. Disease activity and the degree of functional limitations were determined by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Ankylosing Spondylitis Activity Score correlated with C-reactive protein (ASDAS-CRP) and the Bath Ankylosing Spondylitis Functional Index (BASFI). Laboratory examination included determination of C-reactive protein (CRP). Bone mineral density (BMD) of the lumbar spine and femoral neck was determined by the method of dual-energy X-ray absorptiometry on the Hologic Discovery Wi device (S/N 87227). In men with AS, a decrease in BMD (according to the Z-score and T-score) was found in 41.9%, while the percentage of patients with osteoporosis at the level of the femoral neck and lower back was 16.7%. Development of osteoproliferative changes was observed in 42 (40%) patients. Bone mass loss was associated with high activity of the inflammatory process according to ASDAS, BASDAI (r = -0.39, -0.65), and CRP (r = -0.28, -0.38) and low functional capacity according to BASFI (r = -0.27, -0.59), while syndesmophytosis had a reliable association with the age of the patients, the duration of the disease and low functional capacity. Low-energy fractures occurred in 11.4% of men with AS. The presence of fractures was associated with high disease activity (ASDAS, BASDAI, CRP) and was not related to the age of the patients or duration of the disease. A decrease in BMD and the development of fractures were closely associated with high activity of the inflammatory process and low functional capacity, while syndesmophytosis was related to the age of patients and the duration of the disease.

Flare prediction after tapering the dose of tumour necrosis factor inhibitors in patients with axial spondyloarthritis: A nationwide cohort study.

To develop a model for predicting flares after tapering the dose of tumour necrosis factor inhibitors (TNFi) in patients with axial spondyloarthritis (axSpA). Data were obtained from the Korean College of Rheumatology Biologics and Targeted Therapy Registry. In total, 526 patients who received the standard-dose TNFi for at least 1 year and tapered their dose were included in the derivation cohort. The main outcome was a flare occurrence defined as an Ankylosing Spondylitis Disease Activity Score with C-reactive protein (ASDAS-CRP) score of ≥ 2.1 after 1 year of TNFi tapering. The final prediction model was validated using an independent cohort. Among 526 patients, 127 (24.1%) experienced flares. The final prediction model included negative human leucocyte antigen B27 (β = 1.088), inflammatory back pain (β = 1.072), psoriasis (β = 1.567), family history of SpA (β = 0.623), diabetes mellitus (β = 1.092), TNFi tapering by ≥ 50% of the standard-dose (β = 0.435), ASDAS-CRP at tapering (β = 1.029), and Bath Ankylosing Spondylitis Functional Index score at tapering (β = 0.194) as covariates. It showed an excellent discrimination performance (AUC = 0.828). According to the predictive risk, patients were classified into three groups (low-, intermediate-, and high-risk). The probabilities of flares in these groups were 4.5%, 18.1%, and 61.8%, respectively. The performance of the model in the validation cohort was also comparable. The established prediction model accurately predicted the risk of flares after TNFi dose tapering in patients with axSpA using eight simple clinical parameters, which could be helpful to select appropriate patients for tapering their TNFi without flare in daily clinical practice.

This study aimed to clinically and ultrasonographically evaluate enthesitis in patients with spondyloarthritis (SpA) and to determine enthesitis response to anti-tumor necrosis factor (TNF) treatment. Thirty-one SpA patients (22 males, 9 females; mean age: 39.4±10.9 years; range, 22 to 60 years) who started anti-TNF treatment due to their high disease activity were included in the cross-sectional prospective study between May 2017 and January 2018. Ankylosing Spondylitis Disease Activity Score, Bath Ankylosing Spondylitis Disease Activity Index, Ankylosing Spondylitis Quality of Life Questionnaire, Bath Ankylosing Spondylitis Functional Index, and Bath Ankylosing Spondylitis Metrology Index were recorded. Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) and Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Score were utilized for clinical enthesitis evaluation. Patients were ultrasonographically evaluated in accordance with the Madrid Sonographic Enthesitis Index (MASEI) by a blinded sonographer. Patients were clinically and ultrasonographically assessed at baseline and in the third month after the treatment. In the initial evaluation, 24 (77.42%) of the patients had clinical enthesitis, and 30 (96.77%) of the patients had ultrasonographic enthesitis. After anti-TNF treatment, MASES, SPARCC, MASEI-structure, MASEI-thickness, MASEI-bursitis, MASEI-Doppler, MASEI-inflammatory, and MASEI-total scores significantly decreased (p<0.05). There was no significant change in MASEI-damage, MASEI-erosion, and MASEI-calcification scores following the therapy (p>0.05). Anti-TNF treatment may improve clinical and ultrasonographic enthesitis, particularly inflammatory changes. Erosions and calcifications may not ameliorate after three months of anti-TNF treatment.

Profile of HLA-B27-positive enthesitis/spondylitis-related arthritis in Senegal, West Africa

BackgroundEnthesitis/spondylitis-related arthritis (ERA) is a type of juvenile idiopathic arthritis (JIA) frequently associated with HLA-B27. In sub-Saharan Africa, HLA-B27-positive ERA hasn’t been the subject of a specific study.ObjectivesWe aimed to describe the clinical features, disease activity, functional disability and treatment of HLA-B27-positive ERA at diagnosis in Senegal and compare the findings to other populations.MethodsWe conducted a retrospective study by reviewing the medical records of patients diagnosed with ERA with an age of symptom onset < 18 years according to the 2019 PRINTO provisional criteria for ERA from January 2012 to December 2022. We collected demographic, clinical, paraclinical and therapeutic data. Disease activity score was assessed by Ankylosing Spondylitis Disease Activity Score (ASDAS) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Functional disability was assessed using Bath Ankylosing Spondylitis Functional Index (BASFI).ResultsA total of 31 patients with HLA-B27-positive ERA were included. Twenty of 31 (64.5%) were males. Twenty-seven (87%) were Fula (ethnicity). The median age at symptom onset and at diagnosis was 12 years and 19 years, respectively. Seven patients had a family history of Spondyloarthritis. Peripheral arthritis and enthesitis were the most common presenting features at disease onset. Peripheral arthritis was present in 29 (93.5%) and located in the lower limbs in 27/29 (93.1%) patients. Heel enthesitis was present in 26 (83.8%) patients. Axial involvement was present in 27 (87%) patients, dominated by low back pain and sacroiliac pain/ buttock pain in 24 (88.8%) and 22 (81.5%) patients, respectively. Seven (22.5%) patients had anterior uveitis. The ESR and CRP were elevated in 65.5% and 57.1% of cases, respectively. On imaging, sacroiliitis was found in 22 patients. The mean BASDAI was 5.5/10 (77.2% of patients had a high active disease; BASDAI ≥ 4/10). The mean ASDAS-ESR/CRP was 3.8. The mean BASFI was 5.4/10 (80% of patients had high functional disability; BASFI ≥ 4/10). Twenty-seven (87%) patients were treated with methotrexate and non-steroidal anti-inflammatory drugs. After 6 months of treatment, mean BASDAI was 3/10 and mean BASFI was 2.5/10.ConclusionIn our study, HLA-B27-positive ERA was found in our Senegalese cohort mainly in adolescents of the Fula ethnic group. 22 (70.9%) patients developed ankylosing spondylitis at adulthood. The disease was very active at the time of diagnosis with significant functional disability. Treatment was mainly based on methotrexate and NAISDs.

Effectiveness and safety of BCD180, anti-TRBV9&lt;sup&gt;+&lt;/sup&gt; T-lymphocytes monoclonal antibody in patients with active radiographic axial spondyloarthritis: 36-week results of double-blind randomized placebo-controlled phase II clinical study ELEFTA

The aim – to evaluate the clinical effectiveness, safety, pharmacokinetics, pharmacodynamics, and immunogenicity of seniprutug (BCD-180) in patients with radiographic active axial spondyloarthritis (r-axSpA, or ankylosing spondylitis).Subjects and methods. 260 patients with active r-axSpA and inadequate response to nonsteroidal anti-inflammatory drugs (NSAIDs) were randomized into three groups: seniprutug (BCD-180) at doses of 5 mg/kg or 7 mg/kg, or placebo. BCD-180 was administered on weeks 0–12–36. Patients in the placebo group were switched to BCD-180 at a dose of 5 mg/kg at week 24 and continued therapy at week 36. The primary endpoint was the proportion of patients achieving 40% improvement by Assessment in Spondyloarthritis International Society scale (ASAS40) at week 24. Secondary endpoints were proportion achieving ASAS20/40, improvement of 5 out of 6 criteria of ASAS (ASAS5/6), ASAS partial remission, clinically important improvement in ASDAS-CRP (Ankylosing Spondylitis Disease Activity Score with C-reactive protein) (ASDAS-CII) and major improvement in ASDAS-CRP (ASDAS-MI). The dynamics of the disease activity status according to ASDAS-CRP, the BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) and BASFI (Bath Ankylosing Spondylitis Functional Index) indices, as well as the dynamics of laboratory markers (C-reactive protein anderythrocyte sedimentation rate (ESR)) were analyzed. Safety was assessed by the frequency and profile of adverse events (AEs) and adverse reactions (ARs).Results. The proportion of patients achieving ASAS40 at week 24 with seniprutug (BCD-180) at the dose of 7 mg/kg and 5 mg/kg was 51.4% and 40.8%, respectively, compared with 24% in the placebo group (p=0.0012 and p=0.0417, respectively). Analysis of secondary endpoints showed that in patients with r-axSpA, BCD-180 at both study doses was significantly superior to placebo at week 24 in the following measures: decrease in the proportion of subjects with very high disease activity (ASDAS-CRP&gt;3.5) achieving ASDAS-CII, ASAS20, ASAS5/6. A statistically significant decrease in the ASDAS-CRP, BASDAI, BASFI indices, as well as the concentration of CRP and ESR were demonstrated. Tolerability of seniprutug therapy was assessed as acceptable. Infusion reactions were the most common observed adverse events, the vast majority of which were mild to moderate in severity according to CTCAE 5.0 (Common Terminology Criteria for Adverse Events) and developed predominantly during the first administration. The proportion of patients with binding antibodies was 5.1%. However, no neutralizing antibodies were detected.Conclusion. Seniprutug (BCD-180) demonstrated superiority over placebo in clinical efficacy with a favorable safety profile and low immunogenicity as a treatment of r-axSpA.

Anemia and Low Body Mass Index in Axial Spondyloarthritis: Results from ChinaSpA, the Chinese Spondyloarthritis Registry.

Anemia and malnutrition are recognized indicators of suboptimal physical condition in chronic inflammatory diseases. This study aimed to examine the association between anemia, low body mass index (BMI), and clinical outcomes in axial spondyloarthritis (axSpA). This cross-sectional analysis utilized data from the multicenter ChinaSpA cohort. A total of 4146 participants with axSpA were categorized into four groups based on BMI and hemoglobin levels: those with both anemia and low BMI, those with anemia only, those with low BMI only, and those with neither condition. Logistic regression analyses were performed to analyze the association between anemia, low BMI, inflammation status, functional impairment, and disease activity. Anemia was present in 13.94%, low BMI in 11.99%, and both conditions in 2.15% of axSpA participants. Those with both anemia and low BMI showed significantly higher levels of inflammation (hypersensitive C-reactive protein [hsCRP] 30.60mg/L vs. 8.44mg/L), functional impairment (Bath Ankylosing Spondylitis Functional Index [BASFI] 3.80 vs. 2.10), and disease activity (Bath Ankylosing Spondylitis Disease Activity Index [BASDAI] 4.52 ± 2.04 vs. 3.67 ± 2.21; Ankylosing Spondylitis Disease Activity Score calculated with C-reactive protein [ASDAS_CRP] 3.51 ± 1.10 vs. 2.62 ± 1.21) compared to those without these conditions. After adjusting for sex and age, significant associations were observed between elevated hsCRP levels and the presence of low BMI (odds ratio [OR] 1.44, 95%CI 1.17-1.78), anemia (OR 1.91, 95%CI 1.56-2.32), and their concurrent presence (OR 3.59, 95%CI 2.22-5.80). Similarly, increased BASFI was significantly associated with low BMI (OR 1.57, 95%CI 1.25-1.97), anemia (OR 1.47, 95%CI 1.19-1.80), and their combination (OR 3.11, 95%CI 2.02-4.78). All-cause anemia and low BMI are prevalent complications in patients with axSpA, exhibiting a significant correlation with elevated inflammation status and functional impairment. The simultaneous occurrence of anemia and low BMI particularly exacerbates clinical outcomes, emphasizing the critical role of comprehensive nutritional assessment and management in the therapeutic strategy for axSpA.

Fatigue Assessment Using FACIT-F Scale in Spondyloarthropathy Patients and its Correlation with BASDAI and BASFI Scores.

To measure fatigue in axial spondyloarthropathy patients and find its correlation with the disease activity measures. Cross-sectional, descriptive study. Place and Duration of the Study: Rheumatology Unit, Federal Government Polyclinic Hospital, from November 2021 to May 2022. This study included 45 patients fulfilling the ASAS criteria for spondyloarthropathy. Bathankylosing spondylitis disease activity (BASDAI), Bath ankylosing spondylitis functional index (BASFI), and functional assessment of chronic illness therapy- fatigue (FACIT-F) scores were measured for each patient. In this study, there were 9 (20%) female patients and 36 (80%) male patients. There were 39 (86.7%) patients who had ankylosing spondylitis, 4 (8.9%) had axial spondyloarthropathy with peripheral arthritis and 2 (4.4%) had enthesitis-related juvenile idiopathic arthritis. The mean duration of the disease was 5.45 ± 4.19 years. Active disease with a BASDAI score of ≥4 was found in 16 (35.6%) patients while 29 (64.4%) had a BASDAI score <4. Severe fatigue with a FACIT-F score of <30 was found in 31 (68.9%) of the patients while less fatigue with FACIT-F score >30 was found in 14 (31.1%). The mean BASFI score of the cohort was 3.23 ± 2.01. Spearman's rho correlation analysis showed a significant strong correlation between the FACIT-F score, BASDAI and BASFI scores (p<0.001). Patients with active disease and higher BASFI scores had a lower FACIT-F score suggesting more fatigue, thus correlating with the disease activity.
