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.

Background:Recent developments of targeted treatments such as targeted synthetic DMARDs (tsDMARDs) increase the chances of a sustained low disease activity (LDA) or remission state for patients suffering rheumatoid arthritis (RA). tsDMARDs such as baricitinib, an oral inhibitor of the Janus Kinases (JAK1/JAK2) was recently approved for the treatment of RA with an inadequate response to conventional (cDMARD) and biological (bDMARD) therapy. (1, 2).Objectives:Aim of this study is to analyze the effect of baricitinb on disease activity (DAS28, LDA) in patients with RA in real life, to analyze drug persistance and associate these effects with various baseline characteristics.Methods:All RA patients were seen in our outpatient clinic. If a patient was switched to a baricitinib due to medical reasons, these patients were included in our prospective, observational study which started in April 2017. Clinical scores (SJC/TJC 76/78), composite scores (DAS28), PROs (HAQ-DI; RAID; FACIT), safety parameters (not reported in this abstract) as well as laboratory biomarkers were collected at each visit every three months. Linear mixed effects models for repeated measurements were used to analyze the time course of disease activity, patient reported outcomes and laboratory results. We estimated the probabilities of continued baricitinib treatment and the probabilities of LDA and remission by DAS-28 as well as Boolean remission up to one year using survival analysis and explored their association with disease characteristics using multivariable Cox regression. All patients gave informed consent. The study is approved by the local ethics.Results:95 patients were included and 85 analyzed with available follow-up data until November 2019. Demographics are shown in table 1. Mean follow-up duration after starting baricitinib was 49.3 (28.9) weeks. 51 patients (60%) were on monotherapy. Baricitinib survival (95%CI) was 82% (73% to 91%) at one year. Cumulative number (%probability, 95%CI) of patients that attained DAS-28 LDA at least once up to one year was 67 (92%, 80% to 97%) and the number of patients attaining DAS-28 and Boolean remission were 31 (50%, 34% to 61%) and 12(20%, 9% to 30%) respectively. Median time to DAS-28 LDA was 16 weeks (Figure 1). Cox regression analyses did not show any sufficiently precise association of remission or LDA with age, gender, seropositivity, disease duration, concomitant DMARD use and number of previous bDMARDs. Increasing number of previous bDMARDs was associated with poor baricitinib survival (HR=1.5, 95%CI 1.1 to 2.2) while this association was not robust to adjustment for baseline disease activity. Favorable changes were observed in tender and swollen joint counts, pain-VAS, patient and physician disease assessment scores, RAID, FACIT and the acute phase response.Conclusion:In this prospective observational study, we observed high rates of LDA and DAS-28 remission and significant improvements in disease activity and patient reported outcome measurements over time.References:[1]Keystone EC, Taylor PC, Drescher E, Schlichting DE, Beattie SD, Berclaz PY, et al.

Background:Involving the patients with rheumatoid arthritis (RA) in the assessment of their disease may increase their adherence to treatment, improve the disease outcomes and facilitate the application of telehealth. We previously reported an excellent concordance between the Disease Activity Score (DAS-28) performed by physicians and patients at the baseline visit of this prospective study (1).Objectives:To evaluate the persistence of the concordance between the physician’ and the patient’s assessment of disease activity in RA using DAS-28 after one year.Methods:At the baseline visit, patients with RA from 7 Middle Eastern Arab Countries (MEAC) were briefed about DAS-28 by their rheumatologist during a routine consultation and given smartphone access to a video in Arabic language explaining the performance of DAS-28. At 3, 6 and 12 months (± 3 months), the patients were asked to self-report DAS-28, blinded to the physician’s assessment. Concordance between the continuous DAS-28 at each visit was calculated using paired t-test numerically and the Bland-Altman method graphically. Agreement between physician- and patient-DAS categories (remission, low-, moderate- and high disease activity) was calculated at each visit using weighted kappa for category comparison. Weighted kappa of the different agreements were compared over time using their respective confidence intervals (CIs). Predictive factors of positive concordance between physician and patient-DAS were identified using binary logistic regression.Results:The study included 428 patients over a period of three years (2018 to 2020). The mean age of participants was 49.8 years, 82.5% were females, 44.3% had a university degree and the mean disease duration was 11.4 years.At baseline, the average patient-DAS was higher (4.06 (±1.52)) than the physician-DAS (3.97 (±1.52)). The mean difference was -0.09 [95%CI -0.14; -0.04] and most of the pairs were within the limit of agreement in the Bland-Altman graph, indicating a good concordance, particularly in cases of remission.During the study follow-up, 299 patients consulted for visit 2 (69.9% of the total population), 232 for visit 3 (54.2%) and 199 for visit 4 (46.5%). The weighted kappa was 0.80 [95%CI 0.76;0.85] at visit 1 and 0.79 [95%CI 0.72;0.88] at visit 4 (Figure 1 showing kappa for DAS-28, CDAI and SDAI as well). A minor numerical decrease in kappa was observed over time; however, the CIs were overlapping over the four visits and the agreement was considered stable, remaining in the excellent range. At visit 4, a positive concordance between the physician- and the patient-DAS was associated with the profession (lower in blue collar, p=0.001), the educational level (higher in high school and university, p=0.034) and the baseline physician’s DAS (higher in high disease activity, p=0.46).Conclusion:The agreement between the DAS-28 performed by the physician and by the patient was excellent at baseline and remained stable over one year. A positive concordance was associated with the profession, the educational level and the level of disease activity. The present study can help the rheumatologist make informed decisions about the patients who may be suitable for a remote evaluation of their disease activity, that can be of particular interest in the context of the COVID-19 pandemic.References:[1]Ziade N, Saad S, al Mashaleh M, et al.

Background and Aims: The management of IBD entails the use of various treatments (nutrition, medications, and surgery) in order to induce and maintain remission. The assessment of IBD disease activity is based on a combination of symptoms, clinical findings, imaging, and endoscopic procedures. As in any disease, reliable assessment of disease activity or severity is required in order to plan relevant follow-up, decide on appropriate investigations, determine the best treatment option and subsequently assess response to treatment. It is important for proper documentation, follow-up, assessment of response to treatment and communication, especially in patients with IBD, to talk the same language by using validated and widely used scores for disease activity, endoscopic and radiologic activity, and patient reported outcomes both for clinical practice and research. This review aims to highlight key tools available for the assessment of disease activity or severity in individuals (especially children) with IBD.Methods: A literature search was performed using MEDLINE, Pubmed, and the Cochrane Library with the last search date of August 2020. Tools evaluating disease severity across various aspects (clinical, endoscopic, and radiological) were identified and discussed. Those tools validated and specific for children with IBD were included were available.Results: Over time a number of scoring systems have been developed to quantify clinical, endoscopic and imaging assessments in individuals with IBD. While some are exclusively for children or adults, others appear to have relevance to all age groups. In addition, some tools developed in adult populations are utilized in children, but have not expressly been validated in this age group.Conclusions: Although some available scoring tools are appropriate for children with IBD, others require consideration. The development and use of pediatric-specific tools is relevant and appropriate to optimal care of children and adolescents with IBD.

Objective Depression is common in rheumatoid arthritis (RA) patients, exacerbates disease activity, and may decrease response to first-line disease-modifying antirheumatic drugs. This study aimed to determine if depression affects disease activity among Veterans with early RA prescribed methotrexate (MTX). Methods Participants included Veterans enrolled in the Veterans Affairs Rheumatoid Arthritis registry with early RA (onset < 2 years) prescribed MTX. Depression was assessed at enrollment using International Classification of Diseases codes (296.2-296.39, 300.4, 311). Disease activity was measured using the 28 joint count disease activity score (DAS-28) and other core measures of RA disease activity. Propensity score weights were used to adjust depressed (n=48) and non-depressed (n=220) patients on baseline confounders within imputed datasets. Weighted estimating equations were used to assess standardized mean differences in disease activity between depressed and non-depressed patients at six months and one- and two-years follow-up. Results The analytic sample was composed of 268 Veterans with early RA prescribed MTX who were predominantly male (n=239; 89.2%) and older (62.7 years ± 10.6) than general population RA patients. Adjusted estimates indicated that depression was associated with significantly higher DAS-28 at six months (β=0.345; 95% CI: 0.007, 0.682) but not at one- or two-years follow-up. Also, depression was associated with significantly worse pain at six months (β=0.385; 95% CI: 0.040, 0.730) and one-year (β=0.396; 95% CI: 0.042, 0.750) follow-up. Conclusion In early RA, depression is associated with greater short-term disease activity during MTX treatment, as well as more persistent and severe pain.

Introduction. Genetic markers are significant predictive factors in the assessment of therapeutic response of rheumatoid arthritis (RA) to biological medication. Objective. The aim of the study was to determinate the association of TNF-? -308 G/A polymorphism with a high RA activity and its predictive value in therapeutic response after 12 months of treatment with Etanercept. Methods. The study enrolled 132 patients with RA treated with Methotrexate (MTX) and 58 control subjects. The -308 TNF polymorphism was examined using the polymerase chain reaction - restriction fragment length polymorphism (PCR- RFLP). The patients were divided into two groups: group A with A/A and A/G genotype and group G with G/G genotype. After 12 months, beside MTX, Etanercept was introduced in 36 patients. We compared clinical activity among the groups at the beginning and after one year of therapy by using DAS28 SE (Disease activity score with sedimentation). Results. There was no significant difference found in the distribution of G and A allele in the RA group compared to the control group. A significantly higher disease activity was noticed in A compared to the G group (DAS28 SE: 6.31 to 5.81; p<0.05). The patients with A allele kept the majority of the disease activity even after a year of study (DAS28 SE: 5.25 to 3.89). After a year of MTX and Etanercept therapy, a significantly larger proportion of patients in the G group displayed a good clinical response to treatment compared to the A group (81.5% to 25%; p<0.05). The average change of DAS28 SE in G group was 2.24, while in the A group DAS 28 reduction was significantly lower (1.17; p=0.005). Conclusion. There was no significant difference in the frequency of A in the patients with RA compared to healthy subjects. The presence of A allele is associated with more serious clinical presentation of the disease and lower therapeutic response to Etanercept.

Background:During rheumatoid arthritis (RA), initiating conventional synthetic Disease Modifying Anti-Rheumatic Drug (csDMARD) at the early stages of the disease is a mandatory condition to achieve DMARD-free sustained remission (1). Limited data studying the relationship between RA treatment delay and disease activity are available.Objectives:The aim of this study was to assess the impact of csDMARD initiation delay during RA on disease activity.Methods:This is a cross-sectional study including patients with RA (ACR/EULAR criteria).Delays were collected from patients’ interview and were represented respectively by D1, D2 and D3. D1 stands for the lag time separating the first RA symptom onset and rheumatologist consultation. D2 stands for the lag time separating the first RA symptom onset and RA diagnosis. D3 stands for lag time separating the first RA symptom onset and csDMARD initiation. Disease activity was evaluated by: Visual Analogue Scale for pain (VAS), number of tender joints, number of swollen joints, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and Disease Activity Score28 (DAS28).The data were analyzed with descriptive statistics, Student’s t test, chi (2) test, and Spearman correlation using the SPSS statistical package. A p value < 0.05 was considered significant.Results:The study included 100 RA patients (86 women and 14 men), with a mean age of 56.5 ± 12.4 years. The mean age at the onset of RA was 47.5 ± 12.4 years. Median D1, D2 and D3 were respectively 12 months [0-242], 15.7 months [2-252] and 18 months [2-270].Methotrextate was prescribed in 86% of cases. At RA diagnosis, the median values for the following parameters were: VAS 80 [30-100], number of tender joints 10[0-28], number of swollen joints 5 [0-17], ESR 43mm/hour [6-133], CRP 14.1 mg/l [1-120], DAS28 (ESR) 5.22 [2-7.52] and DAS28 (CRP) 4.6 [1-6.93]. After one year of follow-up, the median parameters of the disease activity were respectively: VAS 60 [0-100], number of tender joints 6[0-28], number of swollen joints 2 [0-22], ESR 32 mm/hour [2-106], CRP 7.5 mg/l [1.2-94], DAS28 (ESR) 4.1 [1.4-7.1] and DAS28 (CRP) 3.7 [1.68-6.22]. Significant positive correlation was found between delays in csDMARD initiation and DAS28 (CRP) scores over the first year (p=0.02, r=0.29).Conclusion:In this study, delays in treatment were associated with higher DAS28 (CRP) scores after one year of follow-up. Our results suggest that early identification and treatment of RA leads to improved outcomes and even improved rates of drug-free remission.References:[1]Van Nies JA, Krabben A, Schoones JW, et al.

Background:Assessment of disease activity and quality of life are one of the main indicators for determining the effectiveness of treatment with disease-modifying antirheumatic drugs. In recent years, a new group has entered the market - target synthetic DMARDS, which prove their effectiveness in treating RA comparable to that of biological products.Objectives:The aim of this study is to evaluate the disease activity and quality of life of patients with rheumatoid arthritis (RA) treated with biological agents in comparison with Tofacitinib (real life data from Bulgarian population) and determine whether or not the benefits of different therapies were sustained over a follow up period of 1 year.Methods:164 patients were selected with a mean age 55.34 ± 16SD years, meeting the 1987 ACR and /or ACR/ EULAR (2010) classification criteria for Rheumatoid arthritis (RA). Patients were arranged according to treatment regimens: Tocilizumab (TCL) 30 patients, Certolizumab (CZP) 16, Golimumab (GOL) 22, Etanercept (ETN) 20, Adalimumab (ADA) 20, Rituximab (RTX) 16, Infliximab (INF) 20, Tofacitinib (TOF) 20. Disease activity and quality of life was the primary concern. Independent joint assessor evaluated 28 joints on baseline, 6th and 12th month’s thereafter. CRP was used to measure the inflammatory process.DAS28-CRP, clinical disease activity index (CDAI) and simplified disease activity index (SDAI)were calculated. On baseline all of the patients’ groups had severe disease activity (mean DAS28-CRP > 5.2, mean CDAI > 22, mean SDAI > 26. The quality of life was evaluated via EQ-5D.All of the patients were on stable therapy according to the inclusion criteria, and didn’t interrupt any of the medications including biological or target synthetic treatment.Results:Significant clinical improvement and statistically significant reduction in disease activity were observed in patients treated with bDMARDS and tsDMARDS within 6 months (p <0.005) of treatment and after 12 months of follow-up (p=0.039). The mean value of DAS28-CRP after one year follow up showed an non-inferior effect of Tofacitnib (3.04± 0.81) in comparison to biological treatment (TCL: 3.07 ± 0.73; CZP: 3.06 ± 0.65; GOL: 2.49 ± 0.76; ETN: 2.85 ± 0.55; ADA: 3.15 ± 0.82; RTX: 2.90 ± 0.70; INF: 3.14; ± 0.61; TOF: 3.04± 0.81). An improvement was also observed for the 6 to 12 months of follow-up as we did not detect a significant difference in the activity of the disease assessed by CDAI among the different drug groups.The mean values showing the change of the SDAI over the study period also outline comparable profiles. All of the treatment groups achieved a rapid reduction in disease activity that continued to decrease through the 6 and 12 months period, respectively, as supported by changes in SDAI.The quality of life evaluated with EQ-5D revealed significant improvement on the 6-th month of follow up as well as after 12th month (p<0.005) without significant difference between the observed groups.Conclusion:Real-life data show that patients on biological treatment as well as those on Tofacitinib therapy achieve a significant decrease in disease activity after one year of follow-up. This gives us reason to accept the importance of non-inferior effect of jak-inhibitors and their place in treatment of Rheumatoid arthritis.Disclosure of Interests:Vladimira Boyadzhieva: None declared, Nikolay Stoilov: None declared, Ekaterina Kurteva: None declared, Rumen Stoilov Grant/research support from: R-Pharm

Background:The clinical effectiveness of a patient-reported outcome (PRO) based telehealth intervention offered to rheumatoid arthritis (RA) patients with low disease activity or remission has previously been reported1. The TeRA study showed that PRO-based telehealth follow-up in RA achieved similar disease control as conventional outpatient follow-up among patients with low disease activity or remission. The degree of disease control did not differ between telehealth follow-up offered by rheumatologists or rheumatology nurses.Objectives:To compare the cost-effectiveness of PRO–based telehealth follow-up to patients with RA performed by rheumatologists or rheumatology nurses with conventional outpatient follow-up.Methods:A total of 294 patients were randomized (1:1:1) to either PRO-based telehealth follow-up carried out by a nurse (PRO-TN) or a rheumatologist (PRO-TR), or conventional outpatient follow-up by physicians. Quality of life (EQ-5D) was measured at baseline and at follow-up after one year. The primary outcome was a change in the Disease Activity Score, C-reactive Protetin in 28 joints (DAS-28, CRP).The focus in the health economic evaluation was on the relation between costs and EQ-5D in the period between one year prior to and one year after the intervention. All costs were measured at the individual level and consisted of: intervention costs, health and social care costs, and productivity costs. All cost data were retrieved from Danish population-based registers. Incremental cost-effectiveness rates (ICERs) were calculated on the basis of a comparison of the development in costs and effects in the two intervention groups (separately and combined) with the control group. Bootstrap with 10,000 replications were used to access significance.Results:The difference in health and social care costs during the intervention period compared to the year before were €1,072, - €50 and €519 for the control group, the PRO-TR group and the PRO-TN respectively. Hence, the change in health and social care costs was lower for both intervention groups. The PRO-TR group had a small decrease and it was significantly lower than for the control group (p=0.0027). The difference between health and social care costs in the PRO-TN group compared to the control group was only borderline significant (p=0.067). No statistically significant differences were found in QALY’s between the three groups, all three groups experienced minor, non-significant, declines in QALY over the intervention period. ICER’s were not statistically significant but below known threshold values for the PRO-RN group (ICER=€17,121).Conclusion:It is difficult to obtain statistically significant results for cost-effectiveness in small samples. However, the results point towards a possible cost-saving impact of PRO interventions in patients with low disease activity or remission. The study was unable to conclude if PRO-TR or PRO-TN were most cost-effective. Other relevant considerations, like patient satisfaction or organisational issues, should determine the way of organizing RA disease management in these patients.References:[1]de Thurah A, Stengaard-Pedersen K, Axelsen M, et al.
