Background:Upadacitinib (UPA) is an oral Janus kinase inhibitor that has demonstrated efficacy and safety among patients with ankylosing spondylitis (AS) in the phase 2/3 SELECT-AXIS 1 study.1 If identified, early predictors of treatment response may inform treat-to-target strategies and optimize patient outcomes in AS.Objectives:To determine whether baseline (BL) characteristics or early responses predict clinical response at 1 year in UPA-treated patients with AS.Methods:In the double-blind, randomized, placebo (PBO)-controlled SELECT-AXIS 1 study, patients received UPA 15 mg once daily or PBO until Week 14.1 At Week 14, PBO-treated patients switched to UPA 15 mg; patients originally randomized to UPA continued UPA therapy. Data from patients in the PBO and UPA arms were combined based on overall exposure to UPA; in the switch arm, exposure was defined as current visit minus 14 weeks (time of switch). The following outcomes were assessed at 1 year: Ankylosing Spondylitis Disease Activity Score with C-reactive protein (ASDAS[CRP]) inactive disease (ID; <1.3) and low disease activity (LDA; <2.1), Assessment of SpondyloArthritis International Society (ASAS) partial remission (PR), and ≥40% improvement in ASAS criteria (ASAS40) response. The ability of BL characteristics, efficacy at Week 12, and back pain at Week 12 to predict 1-year outcomes was assessed using a univariable logistic regression model generating odds ratios (ORs; 95% confidence intervals). LASSO regression was used to select the best-fitted multivariable model at Week 12 for each outcome measure.Results:Among 187 patients who received or switched to UPA 15 mg, 70 (37.4%), 134 (71.7%), 73 (39.0%), and 131 (70.1%) achieved ASDAS(CRP) ID, ASDAS(CRP) LDA, ASAS PR, and ASAS40, respectively, following 1 year of UPA treatment. No meaningful predictors of 1-year efficacy outcomes were identified based on BL demographics (including disease duration, gender, and human leukocyte antigen B27 status) or BL disease characteristics (including ASDAS, Bath Ankylosing Spondylitis Disease Activity Index, and CRP levels). In univariable analyses, Week 12 responses based on several disease activity measures and patient-reported outcomes (PROs), including reductions (much better improvement [MBI], ≥30/≥50/≥70% reduction, or improvement) in back pain score, along with lower scores for back pain at Week 12, were associated with the achievement of ASDAS(CRP) ID, ASDAS(CRP) LDA, ASAS PR, and ASAS40 at 1 year (Figure 1). In a multivariable analysis, improvement from BL to Week 12 in back pain score consistently predicted several efficacy outcomes at 1 year.Conclusion:In upadacitinib-treated patients with AS, improvement in PROs and reduction in back pain score at 12 weeks predicted clinical outcomes at 1 year.References:[1]van der Heijde D, et al.

Objective.Evaluate safety and efficacy of intravenous (IV) golimumab (GOL) in patients with active ankylosing spondylitis (AS) through 1 year.Methods.A total of 208 patients were randomized to IV infusions of GOL 2 mg/kg (n = 105) at weeks 0, 4, and every 8 weeks thereafter or placebo (n = 103) at weeks 0, 4, and 12, then crossover to GOL at weeks 16, 20, and every 8 weeks thereafter through Week 52. Efficacy was assessed using the Assessment of Spondyloarthritis international Society (ASAS) criteria, the Ankylosing Spondylitis Disease Activity Score (ASDAS), the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and the Bath Ankylosing Spondylitis Functional Index (BASFI). Health-related quality of life was assessed using the AS Quality of Life (ASQoL) index. Efficacy and safety were monitored through Week 52 and Week 60, respectively.Results.The primary endpoint (ASAS20) and all controlled endpoints at Week 16 were achieved. At Week 52, 69.5% and 65.0% of patients in the GOL group and placebo crossover group, respectively, achieved an ASAS20; 56.2% and 51.5% achieved an ASAS40; 56.2% and 55.3% achieved a BASDAI50; 24.8% and 24.3% achieved ASAS partial remission; and 25.7% and 26.2% met ASDAS inactive disease criteria (all last observation carried forward). Mean changes from baseline to Week 52 in BASFI and ASQoL scores were similar between the GOL group and the placebo crossover group (BASFI: −2.7 and −2.6; ASQoL: −5.5 and −5.4). Through Week 60, 55.4% of all GOL-treated patients had ≥ 1 adverse events (AE); 3.4% had ≥ 1 serious AE.Conclusion.Efficacy was maintained through 1 year with IV GOL 2 mg/kg among patients with active AS. AE were consistent with the known safety profile of GOL.

Background:Interleukin 23 (IL-23) is a pivotal pro-inflammatory cytokine in the Th17/IL-23 axis which became the center of attention in researches during these last decades, especially during spondyloarthritis (1).Objectives:We aimed to study the diagnosis value of IL-23 serum in spondyloarthritis.Methods:We conducted a case-control study, including 144 subjects divided into 2 groups:-G1: 72 patients meeting the Assessment of SpondyloArthritis International Society (ASAS) criteria for spondyloarthritis (SA)-G2: 72 healthy controls matched for age and sex.For each SA patient we collected the following parameters: BASDAI (Bath Ankylosing Spondylitis Disease Activity Index), ASDAS (Ankylosing Spondylitis Disease Activity Score), BASFI (Bath Ankylosing Spondylitis Functional Index), and BASRI (Bath Ankylosing Spondylitis Radiology Index).The IL-23 level was measured using Enzyme-linked immunosorbent assay (ELISA).Erythrocyte Sedimentation rate (ESR) and C-reactive protein (CRP) were also measured.We performed a ROC analysis and computed the air under the curve (AUC) at IL-23 to diagnose SA patients.Statistical analysis was performed using “IBM SPSS Statistics” software version 25.Results:The study included 57 men and 15 women. The mean age was 44.84 ± 13.42 years. The mean age at the onset of the disease was 35.97 ± 12.88 years. The disease duration was 8.54 ± 7.7 years.Seventy-nine per cent of our patients had axial radiographic spondyloarthritis (n=57). Peripheral involvement was found in 45.8% (n=33). Eighteen patients had both axial and peripheral involvement concomitantly. Psoriasis was found in 36.1% of the cases (n=26).The mean BASDAI and ASDAS-CRP were 3.21 ± 1.64 and 3.05 ± 1.51, respectively.The mean was BASFI 3.88 ± 2.69. The mean was BASRI 5.26 ± 4.14.The mean ESR and CRP were 36.74 ± 29.38 mm/hr and 20.45 ± 25.19 mg/dL, respectively.IL-23 level was significantly higher in patients compared to healthy controls (23.1 ± 2.72 pg/mL and 5.02 ± 0.59 pg/mL, respectively, p<0.0001).As shown in Figure 1, the AUC value to distinguish between spondyloarthritis and healthy control was 0.705 (p<0.0001). IL-23 cut-off was 7.96 pg/mL (Sensibility= 69.4%, specificity=98.6%).Figure 1.AUC at IL-23 between SA patients 0.705 (p<0.0001) Nevertheless, no correlation was found between serum IL-23 levels and the following parameters: ESR, CRP, BASDAI, ASDAS-CRP, BASFI and BASRI.Conclusion:As reported to previous studies, our study showed that IL-23 is significantly higher in SA patients (2).Interestingly, IL-23 was able to distinguish between SA patients and healthy controls with a cut-off of 7.96 pg/mL. This finding suggests that IL-23 may be practical for the diagnosis of SA.References:[1]K V, D E.

Background:According to international recommendations, the Ankylosing Spondylitis Disease Activity Score (ASDAS) is the preferred score for assessing disease activity in axial spondyloarthritis (axSpA) [1]. However, routine determination of C-reactive protein (CRP) to calculate ASDAS values takes hours to days. This limits the use of ASDAS in clinical routine and clinical trials and hinders the implementation of treat-to-target approaches in axSpA. Whereas quick quantitative CRP (qCRP) tests allow CRP assessment within a few minutes. In a pilot project the performance of qCRP-based ASDAS assessment (ASDAS-qCRP) was already investigated in a single center study of 50 newly diagnosed, bDMARD-naïve axSpA patients with promising results [2].Objectives:To validate the ASDAS-qCRP in a prospective, multicenter study of axSpA patients in a typical axSpA cohort with an appropriate sample size.Methods:The study was conducted in five centers in Germany. Consecutive adult (≥ 18 years) axSpA patients were included. In addition to a rheumatological assessment, including patient reported outcomes (PROs), routine CRP and erythrocyte sedimentation rate (ESR) were measured in the local labs. Additionally, a qCRP testing with the „QuikRead go instrument“ (Aidian Oy, Finland) was performed at the study center (measurement range 0.5 - 200 mg/l for hematocrit concentrations of 40 – 45%). Statistical analysis included descriptive statistics, cross tabulation and weighted Cohen´s kappa comparing disease activity categories, Bland-Altman plots and intraclass correlation coefficient (ICC) for ASDAS-CRP and ASDAS-qCRP.Results:In this study 251 axSpA patients were included between January and September 2020 (mean age: 38.4 years; mean disease duration: 6.2 years, 159 patients (63.3%) were male, 211 (84.1%) HLA-B27 positive and 195 (77.7%) were classified as radiographic axSpA). 143 patients (57.0%) were treated with bDMARDs. CRP and qCRP showed mean values of 2.12 and 2.17 mg/l, respectively. With the ASDAS-qCRP, 242 patients (96.4%) were assigned to the same disease activity category as compared to the ASDAS based on the conventional lab CRP measurement (Table 1). Weighted Cohen´s kappa was 0.966 (95%CI: 0.943; 0.988). ICC for ASDAS-CRP- and ASDAS-qCRP-values was 0.997 (95%CI: 0.994; 0.999). The agreement of ASDAS-qCRP and ASDAS-CRP is shown in a Bland-Altman plot (Figure 1).Table 1.Disease activity categories by ASDAS-qCRP vs. ASDAS-CRPASDAS-qCRP (n = 251)Inactive Disease(< 1.3)Low Disease Activity (1.3 - < 2.1)High Disease Activity (2.1 - 3.5)Very high Disease Activity (> 3.5)ASDAS-CRPInactive Disease(< 1.3)56 (22.3%)2 (0.8%)Low Disease Activity (1.3 - < 2.1)62 (24.7%)7 (2.8%)High Disease Activity (2.1 - 3.5)97 (38.6%)Very high Disease Activity (> 3.5)27 (10.8%)The fields highlighted in red indicate that disease activity categories do not match.ASDAS = Ankylosing Spondylitis Disease Activity Score, CRP = C-reactive protein, qCRP = quick quantitative CRPConclusion:The ASDAS-qCRP and ASDAS-CRP showed an almost perfect agreement on the assignment to disease activity categories (96%) with the important advantage of time. With ASDAS-qCRP, rheumatologists could base their clinical decision-making on a disease activity measurement by using a composite score immediately. ASDAS-qCRP, therefore, can be integrated in clinical routine and clinical trials in the future and may facilitate implementation of the treat-to-target concept in axial SpA.References:[1]Smolen JS, et al.

Background:Axial spondyloarthritis (ax-SpA) is a chronic rheumatic disease that mainly affects men. However, the female form of ax-SpA remains insufficiently studied.Objectives:The aim of this study was to determine the clinical characteristics, the disease activity and the functional impact of female ax-SpA in comparison with male ax-SpA.Methods:This is a retrospective study including patients diagnosed with ax-SpA fulfilling the criteria of the Assessment of SpondyloArthritis international Society (ASAS) 2009.Clinical parameters, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Bath ankylosing spondylitis disease activity index (BASDAI) and Bath ankylosing spondylitis functional index (BASFI) were compared between groups of female and male ax-SpA.Results:Two hundred ax-SpA patients were included with 31% of female (n=62) and a mean age of 43,3 ± 11,2 years.The mean age at onset of symptoms was 31,8 ± 8,9 years for women and 25,3 ± 9,1 years for men (p <0,0001). The mean age at diagnosis was 36,4 ± 9,6 years for women and 31,7 ± 10,4 years for men (p = 0,003). Ax-SpA with juvenile onset was noted in 1,7% of women and 12,1% of men (p = 0,02). Male ax-SpA were significantly more smokers (46.8% vs 5.4%; p <0.001). The mean duration of morning stiffness was 11,3 ± 9,2 minutes for women versus 21,6 ± 19,3 minutes for men (p = 0,005).The mean ESR was 42,4 ± 29,8 mm for women and 28,3 ± 23,4 mm for men (p = 0,001). Radiographic sacroiliitis was present in 69,3% of women versus 84,7% of men (p = 0,01). The use of anti-TNF alpha was less frequent in women (29% vs 48,5%; p = 0,01).Our study didn’t found a statistically significant difference in peripheral manifestations, extraarticular manifestations, CRP, BASDAI and BASFI between the two groups.Conclusion:Female ax-SpA seems to have a better prognosis than male with older age in disease onset, less inflammation, less radiographic sacroiliitis and less use of biological treatments.References:[1]Rusman T, et al.

Objective: Assessment of ankylosing spondylitis activity patterns during pregnancy using BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) and ASDAS-CRP (Ankylosing Spondylitis Disease Activity Score — C-Reactive Protein) disease activity indices.Materials and methods. The prospective study included 36 pregnant women with AS (modified New York AS criteria, 1984). Patients’ mean age was 31.6±4.8 years, mean age at AS onset was 21.8±10.9, and disease duration 134.9±89.3 months. The control group included 30 healthy pregnant women with no history of back pain and arthritis, their mean age was 28.2±4.5 years. In the I trimester of pregnancy 10 (33.3%) As patients experienced back pain, while in the III trimester already 15 (50%) had back pain. Throughout pregnancy, the intensity of back pain in the I, II и III trimesters based on numeric scale was on average 1.9±0.9; 2.1±1.1 and 2.1±0.8. BASDAI and ASDAS-CRP were used to measure disease activity on gestational Weeks 10–11, 20–21 and 31–32. The time of conception BASDAI score was assessed retrospectively at the 1st visit.Results and discussion. BASDAI mean values at the time of conception and I, II и III trimesters of pregnancy were: 2.3±1.9; 2.8±1.72 (p<0,05 vs month of conception); 3.2±1.9 and 3.3±2.1 respectively. Mean ASDAS-CRP in the I, II и III trimesters were 1.9±0.7; 2.3±0.9 and 2.2±0,8 respectively. There was a trend to CRP increase in the II and III trimesters vs the I: median CRP values in the I, II and III trimesters were 5.7 [1.6; 6.2], 8.0 [2.1; 9.6] and 7.9 [2.0; 9.2] mg/L, respectively. Percentages of patients with high disease activity based on BASDAI scores in the I, II and III trimesters were 30.6; 34.3 and 34.3%; based on ASDAS-CRP — 36.1; 57.5 and 53%, respectively. Throughout pregnancy, BASDAI scores were lower in the control group than in AS patients (p<0.01). However, no differences were found when comparing BASDAI values of AS patients and healthy women with back pain during pregnancy. The level of fatigue did not differ between pregnant women with AS (median 5[3; 7] and 5[3; 6]) and healthy controls (5[3; 8] and 5[4; 6]) in the I and II trimesters, while in the III trimester, fatigue in healthy pregnant women (6[4; 8]) was more pronounced than in AS patients (5[3; 6], p=0.01). Throughout pregnancy, the intensity of back pain in AS patients and healthy pregnant women with back pain did not differ (p<0.05). Median pain intensity in the I, II and III trimesters was 3[2; 4]; 4[3; 5]; 3[2; 6] and 2,5[1; 4]; 3[2; 7]; 4[2; 6], respectively. A high (rs ≥0,7) correlation of all BASDAI components with the index itself in each trimester of pregnancy, except for joint pain in the month of conception, and in the I and III trimesters was established in the group of pregnant women with AS. The control group had quite high correlation (rs >0.7) of fatigue severity with the BASDAI index in the I and II trimesters of pregnancy and moderate correlation (rs >0.53) in the III trimester; as wells as moderate (rs >0.5-0.69) correlation between back pain and BASDAIConclusion. A trend towards increasing AS activity based on BASDAI and ASDAS-CRP scores and CRP levels was established for the first half of pregnancy. Later in pregnancy these increased values failed to return to normal until the end of gestation. The percentage of AS patients with highto-moderate disease activity throughout pregnancy was lower based on BASDAI score vs based on ASDAS-CRP. Some BASDAI components (fatigue and back pain) reflect not only the activity of AS, but also changes associated with physiological pregnancy. The BASDAI index requires adaptation for use in pregnancy

ABSTRACT Intestinal bacterial dysbiosis has been increasingly linked to ankylosing spondylitis (AS), which is a prototypic and best studied subtype of spondyloarthritis (SpA). Fungi and bacteria coexist in the human gut and interact with each other. Although they have been shown to contribute actively to health or disease, no studies have investigated whether the fungal microbiota in AS patients is perturbed. In this study, fecal samples from 22 AS patients, with clinical and radiographic assessments, and 16 healthy controls (HCs) were collected to systematically characterize the gut microbiota and mycobiota in AS patients by 16S rRNA gene- and ITS2-based DNA sequencing. Our results showed that the microbiota of AS patients was characterized by increased abundance of Proteobacteria and decreased Bacteroidetes, which was contributed by enrichment of Escherichia-Shigella, Veillonella, Lachnospiraceae NK4A136 group, and reduction of Prevotella strain 9, Megamona, and Fusobacterium. The gut mycobiota of AS patients was characterized by higher levels of Ascomycota, especially the class of Dothideomycetes, and decreased abundance of Basidiomycota, which was mainly contributed by the decease of Agaricales. Compared to HCs, decreased ITS2/16S biodiversity ratios and altered bacterial-fungal interkingdom networks were observed in AS patients. Compared with nonsteroidal anti-inflammatory drugs (NSAIDs), treating AS patients with biological agents induced obvious changes in the gut mycobiota, and this result was highly associated with disease activity indexes, including AS disease activity index (ASDAS) C-reactive protein (asCRP), erythrocyte sedimentation rate (ESR), and Bath AS disease activity index (BASDAI). In addition, altered mycobiota in AS patients was also found associated with the degree of radiographic damage. IMPORTANCE The human gut is colonized by diverse fungi (mycobiota), and fungi have long been suspected in the pathogenesis of SpA. Our study unraveled a disease-specific interkingdom network alteration in AS, suggesting that fungi, or the interkingdom interactions between bacteria and fungi, may play an essential role in AS development. However, our study is limited by sample size, and in-depth mechanism studies and additional large-scale investigations characterizing the gut mycobiome in AS patients are needed to form a foundation for research into the relationship between mycobiota dysbiosis and AS development.

Objective.The aim of this study was to evaluate rate and predictive factors of loss of remission and disease flare in patients with axial spondyloarthritis (axSpA) receiving antitumor necrosis factor (anti-TNF) treatment.Methods.In this retrospective multicenter study, patients with axSpA, according to the Assessment of Spondyloarthritis international Society (ASAS) criteria, treated with adalimumab, etanercept, or infliximab with a minimum followup of 12 months and satisfying the ASAS partial remission criteria and/or Ankylosing Spondylitis Disease Activity Score (ASDAS) inactive disease were studied. Disease flare was defined as a Bath Ankylosing Spondylitis Disease Activity Index score > 4.5 or ASDAS score > 2.5 on at least 1 occasion.Results.One hundred seventy-four patients with axSpA were studied. After a median [interquartile range (IQR)] followup of 4 years (2–6), 37 patients (21.2%) experienced a loss of remission and 28 (16.1% of the whole study group) a disease flare. Median (IQR) duration of remission in patients who lost this status was 1 year (0.625–2). Higher median erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) values, continuous nonsteroidal antiinflammatory drug (NSAID) use, and an ASDAS-CRP ≥ 0.8 during the remission period were significantly associated with both loss of remission and disease flare. At the multivariate analysis, continuous NSAID intake (OR 4.05, 95% CI 1.4–11.74, p = 0.010) and ESR > 15 (OR 2.90, 95% CI 1.23–6.82, p = 0.015) were the only factors predictive of disease reactivation.Conclusion.In this study, loss of remission and disease flares occurred, respectively, in about 21% and 16% of the patients with axSpA who achieved a state of remission while receiving anti-TNF therapy. Residual disease activity was associated with disease reactivation.

Background: The aim of this study was to assess the serum chitotriosidase (ChT) and neopterin levels in patients with ankylosing spondylitis (AS) and to evaluate whether serum ChT and neopterin levels are related to disease activity. Methods: A total of 86 patients with AS were included in the study. Patients were divided into two groups based on Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores: The active AS patients group included 40 patients who had a BASDAI score ⩾4. The inactive AS patients group included 46 patients who had a BASDAI score <4. We compared the serum level of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), ChT and neopterin between the two groups. Results: Active AS patients had significantly higher ESR, CRP, serum ChT and neopterin levels compared with the inactive AS patients group ( p < 0.05). Positive correlations were found between serum ChT levels and ESR ( r = 0.87, p = 0.005), and CRP levels ( r = 0.86, p = 0.006). Also, there was a positive significant correlation between serum ChT levels and BASDAI scores ( r = 0.67, p = 0.03). No correlation was found between serum neopterin levels and the BASDAI scores, ESR, and CRP levels ( p > 0.05). Higher disease activity (BASDAI score ⩾4) was found to be associated with ChT ( p = 0.012) in the multiple logistic regression analysis. Conclusion: The present study emphasized that serum ChT levels can be useful in the determination of the disease activity of AS patients.

The C-reactive protein to prealbumin ratio (CPR) and fibrinogen to prealbumin ratio (FPR) in serum are two emerging biomarkers. The purpose of this study is to explore the relationship between these two markers and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Ankylosing Spondylitis Disease Activity Scores (ASDAS). A total of 163 patients with AS and 120 healthy examinees were included in this study. The t-test and Mann-Whitney U ranking test were used to analyze the differences between groups. The spearman-test was used to analyze the correlation between erythrocyte sedimentation rate (ESR), c-reactive protein (CRP), fibrinogen (Fib), prealbumin (PAlb), CPR, FPR, and AS disease activity in the test group. We generated the receiver operating characteristic curves (ROC) of CPR and FPR and determined the discriminating ability by calculating the area under the curve (AUC). Compared with the healthy group, ESR ( p < 0.001), CRP ( p < 0.001), Fib ( p < 0.001), CPR ( p < 0.001), and FPR ( p < 0.001) of AS patients were significantly increased, while PAlb was significantly reduced. CPR and FPR were more correlated to ASDAS-CRP. CPR was positively correlated with CRP, ESR, BASDAI, and ASDAS-CRP in AS patients ( r = 0.959, p < 0.001, r = 0.717, p < 0.001, r = 0.704, p < 0.001, r = 0.763, p < 0.001). FPR was positively correlated with CRP, ESR BASDAI, and ASDAS-CRP in AS patients ( r = 0.779, p < 0.001, r = 0709, p < 0.001, r = 0.551, p < 0.001, r = 0.763, p < 0.001). ROC showed that the AUC levels of CPR and FPR were high (AUC = 0.952 and AUC = 0.893). CPR and FPR are two promising new biological indicators for assessing disease activity in AS patients.
