Down-titration, or discontinuing infliximab, has proven to be feasible in RA patients. Therefore, our local treatment protocol includes tapering infliximab dose. This observational study describes the prevalence of successful down-titration in daily clinical practice and its effect on costs and quality of life (QoL).MethodsInfliximab was down-titrated with 25% of the original dose (3 mg/kg) every 8–12 weeks without interval change until discontinuation or flare in all RA patients with stable low 28-joint disease activity score (DAS28) and stable treatment for >6 months. During 1 year DAS28, RA medication, outpatient clinic visits, RA related absenteeism and EuroQoL5D (European QoL questionnaire, EQ5D) were documented. Prevalence of successful down-titration and changes in DAS28, QoL and costs were described.ResultsIn 16% (95% CI 6 to 26) and 45% (95% CI 31 to 59), respectively, infliximab could be discontinued or down-titrated. Mean infliximab dose decreased significantly from 224 mg (95% CI 212 to 236 mg) at start, to 130 mg (95% CI 105 to 154 mg) after 1 year. Median DAS28 increased from 2.5 (p25–75=2.0–2.9) to 2.8 (2.2–3.6) (p=0.002). Extra corticosteroids were given in 8% of the visits. Disease modifying antirheumatic drugs were seldom changed. There was no statistical difference in QoL after down-titration. Mean reduction in the costs was €3474 (95% CI 2457 to 4492) per patient.ConclusionIn the majority of patients with stable low DAS28 and stable treatment, infliximab can be down-titrated or discontinued, which results in a considerable reduction in costs without influencing QoL.

Abstract Objectives An efficient pharmacological response to MTX treatment in RA patients relies on the retention and accumulation of intracellular MTX-polyglutamates catalysed by the enzyme folylpolyglutamate synthetase (FPGS). We recently identified a partial retention of FPGS intron 8 (8PR) as a prominent splice variant conferring FPGS dysfunction and decreased MTX polyglutamylation in acute lymphoblastic leukaemia. Here, we explored the association between FPGS 8PR levels and lack of MTX responsiveness in RA patients. Methods Thirty-six patients undergoing MTX treatment were enrolled from the Combinatie behandeling Reumatoide Artritis (COBRA)-light trial. RNA was isolated from blood samples at baseline, 13 weeks and 26 weeks of therapy, from patients in either COBRA-light (n = 21) or COBRA (n = 15) treatment arms. RT-qPCR analysis was used to assess RNA levels of FPGS 8PR over wild-type FPGS (8WT). Results In the COBRA-light treatment arm, higher baseline ratios of 8PR/8WT were significantly associated with higher 44-joint disease activity score (DAS44) at 13 and 26 weeks. Higher baseline ratios of 8PR/8WT also trended towards not obtaining low disease activity (DAS <1.6) and becoming a EULAR non-responder at 13 and 26 weeks. In the COBRA-treatment arm, a significant association was observed between high baseline 8PR/8WT ratios and higher DAS44 score at 26 weeks. Higher 8PR/8WT ratios were associated with non-response at week 26 based on both low disease activity and EULAR criteria. Conclusion This study is the first to associate alterations in FPGS pre-mRNA splicing levels with reduced responsiveness to MTX treatment in RA patients. Trial registration ISRCTN55552928.

Objective.To evaluate the intensity of xerostomia and hyposalivation in subjects with rheumatoid arthritis (RA) as well as the effects of these conditions on functional incapacity and disease activity.Methods.The study sample comprised 236 individuals of both sexes who had RA. All the individuals were submitted to clinical evaluation and unstimulated sialometry. Functional capacity was determined by using the Health Assessment Questionnaire (HAQ), xerostomia was assessed using the Xerostomia Inventory, and disease activity was evaluated with the 28-joint Disease Activity Score (DAS28). The effect of Sjögren syndrome (SS) was analyzed, and the sample was divided into 2 groups: RA (191 subjects) and RA/SS (45 subjects).Results.The Xerostomia Inventory showed positive and significant correlation with fatigue (r = 0.243; p < 0.0001), number of painful joints (r = 0.218; p = 0.001), HAQ (r = 0.279; p < 0.0001), and DAS28 (r = 0.156; p < 0.0001). On regression analysis, both xerostomia (OR 3.89, 95% CI 1.84–8.23, p < 0.001) and DAS28 (for severe disease activity: OR 13.26, 95% CI 3.15–55.79, p < 0.001) showed influence on functional incapacity. Forty-five individuals (19.1%) presented with secondary SS, and having this diagnosis was not associated with disease activity or functional capacity.Conclusion.Xerostomia demonstrated an adverse effect on quality of life of subjects with RA, being associated with a reduction in functional capacity. In this clinical setting, xerostomia can be monitored as a marker of worse clinical evolution.

Background:Ankylosing Spondylitis Disease Activity Score (ASDAS) is a composite index measuring disease activity in axial spondyloarthritis (axSpA). It includes questions from the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Patient Global Assessment (PGA), and inflammation biomarkers. However, ASDAS calculation is not always possible because PGA is sometimes not collected.Objectives:To develop an alternative ASDAS to be used in research settings when PGA is unavailable.Methods:Longitudinal data from 4 axSpA cohorts and 2 RCTs were combined. Observations were randomly split in a development (N=1026) and a validation cohort (N=1059). Substitutes of PGA by BASDAI total score, single or combined individual BASDAI questions, and a constant value, were considered. In the development cohort, conversion factors for each substitute were defined by Generalized Estimating Equations. Validation was performed in the validation cohort according to the OMERACT filter, taking into consideration: 1) Truth (agreement with original-ASDAS in the continuous score, by intraclass correlation coefficient -ICC- and in disease activity states, by weighted kappa) 2) Discrimination (standardized mean difference –SMD- of ASDAS scores between high/low disease activity states defined by external anchors e.g Patient Acceptable Symptom State –PASS-; agreement -kappa- in the % of patients reaching ASDAS improvement criteria according to alternative vs. original formulae) 3) Feasibility.Results:Taking all psychometric properties into account and comparing the different formulae (Table), alternative-ASDAS using BASDAI total as PGA replacement proved to be: 1) truthful (agreement with original-ASDAS: ICC=0.98, kappa=0.90); 2) discriminative: it could discriminate between high/low disease activity states (e.g. scores between PASS no/yes: SMD=1.37 versus original-ASDAS SMD=1.43) and was sensitive to change (agreement with original-ASDAS in major improvement/clinically important improvement criteria: kappa=0.93/0.88; 3) feasible (BASDAI total often available; conversion coefficient≈1).Table.Psychometric properties of alternative ASDAS formulaeConclusion:Alternative-ASDAS using BASDAI total score as PGA replacement is the most truthful, discriminative and feasible instrument. This index enables ASDAS calculation in existing cohorts without PGA.Disclosure of Interests:Augusta Ortolan: None declared, Sofia Ramiro: None declared, Floris A. van Gaalen: None declared, Tore K.

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.

The efficiency of glucocorticoid (GC) therapy for systemic lupus erythematosus (SLE) is beyond question and is confirmed by the experience gained over many decades of their use. However, there are many problems with prolonged GC use, even in its low and medium doses. In particular, the development of GC-associated irreversible organ damages significantly worsens prognosis and causes a decrease in quality of life and social adaptation and a substantial increase in treatment costs. On the other hand, the current capabilities of early diagnosis, pathogenetic therapy, and monitoring in many patients with SLE allow for maintaining low disease activity and remission, the conditions in which the feasibility of further GC treatment can and should be decided. The paper gives the data available in the literature and the authors’ own studies on the possibility and prospects of GC withdrawal in SLE patients in a stage of low disease activity and remission.

AimsTo determine whether the proportion of time systemic lupus erythematosus patients achieve remission/low disease activity state (LDAS) is associated with a better quality of life (QoL).Patients and methodsPatients from a well-established multiethnic, multicentre US cohort were included: remission: Systemic Lupus Activity Measure (SLAM) score=0, prednisone≤5 mg/day and no immunosuppressants); LDAS not in remission, SLAM score≤3, prednisone≤7.5 mg/day, no immunosuppressants; the combined proportion of time patients were in these states was the independent variable. The endpoints were the Physical and Mental Components Summary measures (PCS and MCS, respectively) and the individual subscales of the Short Form (SF)-36 at the last visit. Linear regression was used to estimate the association between the proportion of follow-up time in remission/LDAS and the SF-36 measures with and without adjustment for possible confounders.ResultsFour hundred and eighty-three patients were included. The per cent of time on remission/LDAS was associated with better QoL after adjusting for potential confounders; for the PCS the parameter estimate was 9.47 (p<0.0001), for the MCS 5.89 (p=0.0027), and for the subscales they ranged between 7.51 (p=0.0495) for mental health and 31.79 (p<0.0001) for role physical.ConclusionsThe per cent of time lupus patients stay on remission/LDAS is associated with a better QoL as measured by SF-36.
