Efficacy of risankizumab across subgroups in patients with active psoriatic arthritis: a post hoc integrated analysis of the phase 3 KEEPsAKE 1 and KEEPsAKE 2 randomized controlled trials

In the KEEPsAKE 1 (NCT03675308) and KEEPsAKE 2 (NCT03671148) phase 3 trials, risankizumab demonstrated greater efficacy compared with placebo in patients with active psoriatic arthritis (PsA). This post hoc integrated analysis evaluated achieving the following efficacy outcomes at weeks 24 and 52 by baseline demographics and clinical characteristics: ≥20%/50%/70% improvement in American College of Rheumatology response criteria (ACR20/50/70), ≥90% improvement in Psoriasis Area and Severity Index, minimal disease activity status, Low Disease Activity status (Disease Activity in Psoriatic Arthritis), and minimal clinically important difference in pain. Baseline demographics and clinical characteristics were similar between risankizumab (n = 707) and placebo (n = 700) groups. Numerically higher ACR20 response rates at week 24 (primary endpoint) were observed among the risankizumab (46.3%−60.1%) vs. placebo (15.5%−36.2%) cohorts, regardless of subgroups. At week 52, consistent proportions of patients randomized to risankizumab achieved ACR20 (48.6%−75.8%) while those initially randomized to placebo and switched to risankizumab experienced an improvement from week 24 (43.7%−63.9%), regardless of subgroups. Similar trends were observed for other efficacy measures assessing rigorous skin response criteria, composite measures of overall disease activity, and PsA-related symptoms. Risankizumab treatment was efficacious among patients with varying demographic and psoriatic disease characteristics through 52 weeks.

Suppression of inflammation in ulcerative colitis rats by avocado and pomegranate

BackgroundPomegranate seed oil (PSO) and avocado seed oil (ASO) are natural polyphenols with established anti-inflammatory activity. PurposeThis study aimed to investigate the molecular mechanisms underlying the therapeutic efficacy of PSO and ASO in experimental ulcerative colitis (UC) with reference to sulfasalazine (SLZ). MethodsEighty male albino rats were divided equally into 8 groups; Normal, PSO, ASO, SLZ, UC-control, (UC+PSO), (UC+ASO) and (UC+SLZ) groups. Colitis was induced by intra-rectal injection of acetic acid. PSO (0.5ml/ 200g), ASO (1ml/ 250g) and SLZ (100mg/kg) were administered orally once/day for 14 days, 24h after colitis induction. Colitis was evaluated by measuring disease activity index (DAI), colon weight/length ratio and histologic inflammatory score. Vascular endothelial growth factor receptor-2 (VEGFR-2), colonic macrophage migration inhibitory factor (MIF), and malondialdehyde (MDA) were determined. Colonic gene expression of TNF-α, VEGF and heme oxygenase-1 (HO-1) were also estimated. ResultsPSO and ASO treatments to UC rats significantly reduced DAI, weight/length ratio, VEGFR-2, and colon histologic inflammatory score versus UC-controls. ASO significantly suppressed MIF levels and TNF-α expression greater than PSO. However, PSO was more significant than ASO in reducing MDA levels and up-regulating HO-1 expression. Both oils significantly down-regulated VEGF expression. The obtained biochemical and histological changes induced by UC were nearly corrected by SLZ. ConclusionThe proved beneficial effect of PSO and ASO as anti-inflammatory, anti-angiogenic, and antioxidant in UC rats could be mediated by suppression of TNF-α, VEGF, and MIF and up-regulation of HO-1.

Serum neurofilament light chain levels as multiple sclerosis biomarker

Cumulative neuroaxonal damage is the main cause of disability in multiple sclerosis (MS), although it may remain clinically silent for many years. In this article, the authors describe their research study measuring serum levels of the neurofilament light chain in patients with MS to assess how they correlated to disease severity and degree of disability in an Egyptian population. They demonstrate how serum levels of the neurofilament light chain are associated with clinical and MRI‐related measures of disease activity, supporting their use as an easily accessible, low cost and non‐invasive biomarker.

Accurate, Robust, and Scalable Machine Abstraction of Mayo Endoscopic Subscores From Colonoscopy Reports.

The Mayo endoscopic subscore (MES) is an important quantitative measure of disease activity in ulcerative colitis. Colonoscopy reports in routine clinical care usually characterize ulcerative colitis disease activity using free text description, limiting their utility for clinical research and quality improvement. We sought to develop algorithms to classify colonoscopy reports according to their MES. We annotated 500 colonoscopy reports from 2 health systems. We trained and evaluated 4 classes of algorithms. Our primary outcome was accuracy in identifying scorable reports (binary) and assigning an MES (ordinal). Secondary outcomes included learning efficiency, generalizability, and fairness. Automated machine learning models achieved 98% and 97% accuracy on the binary and ordinal prediction tasks, outperforming other models. Binary models trained on the University of California, San Francisco data alone maintained accuracy (96%) on validation data from Zuckerberg San Francisco General. When using 80% of the training data, models remained accurate for the binary task (97% [n = 320]) but lost accuracy on the ordinal task (67% [n = 194]). We found no evidence of bias by gender (P = .65) or area deprivation index (P = .80). We derived a highly accurate pair of models capable of classifying reports by their MES and recognizing when to abstain from prediction. Our models were generalizable on outside institution validation. There was no evidence of algorithmic bias. Our methods have the potential to enable retrospective studies of treatment effectiveness, prospective identification of patients meeting study criteria, and quality improvement efforts in inflammatory bowel diseases.

Comparative Effectiveness of Tofacitinib and Adalimumab in Axial Spondyloarthritis: A Real-World Clinical Context Multicenter Study.

Tofacitinib, an oral Janus kinase inhibitor, is a putative choice in the treatment of axial spondyloarthritis (AxSpA). The objective of this study was to compare the effectiveness and tolerability of tofacitinib with adalimumab, in AxSpA, in a real-world clinical setting. In this multicentric medical records review study, adult patients with active AxSpA treated with either tofacitinib 5 mg twice daily or adalimumab 40 mg subcutaneously fortnightly were recruited. Effectiveness was measured with Ankylosing Spondylitis Disease Activity Score (ASDAS) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Drug-cost analysis was calculated with Incremental Cost-Effectiveness Ratio (ICER drug ). Among the 266 patients, 135 were treated with tofacitinib and 131 with adalimumab (follow-up: 6.5 ± 1.6 months). Mean improvement of BASDAI (3.39 ± 0.09 vs. 3.14 ± 1.16, respectively) and that of ASDAS (1.78 ± 0.68 vs. 2.07 ± 2.08, respectively) were comparable between the adalimumab and tofacitinib groups. A higher proportion of patients achieved BASDAI50 response in the second (49.5% vs. 31.6%) and fourth month (83.9% vs. 62.8%) and ASDAS low disease activity in the fourth month (71.6% vs. 47.9%) in the adalimumab group. All disease activity measurements were similar by the sixth month in both groups. A higher proportion of patients in the tofacitinib group than in the adalimumab group required change in therapy (14.8% vs. 7.6%, respectively). ICER drug for adalimumab compared with tofacitinib was US $188.8 per patient in the adalimumab group for each person-month with BASDAI <4. Tofacitinib showed comparable effectiveness with adalimumab in patients with AxSpA at the sixth month, despite lesser response in the initial months, with favorable ICER drug .

Is the patient-perceived impact of psoriatic arthritis a global concept? An international study in 13 Arab countries (TACTIC study).

The Psoriatic Arthritis Impact of Disease (PsAID-12) questionnaire, a recommended measure of patient-reported impact for psoriatic arthritis (PsA), was initially developed in Europe and may lack universal validity. Recognizing the need for a culturally appropriate tool for Arab patients, this study aimed to TranslAte, CulTurally adapt, and validate the PsAID in ArabIC (TACTIC). The PsAID-12 was translated into Arabic using a rigorous process of double translation, back-translation, and cognitive debriefing. The Arabic version was then validated through a study conducted in 13 Arab countries in 2022. Participants were consecutive literate adult patients diagnosed with PsA and fulfilling the CASPAR criteria. Collected data included PsAID-12, disease activity, and legacy patient-reported outcomes. Psychometric properties, such as internal consistency, construct validity, and test-retest reliability, were examined. Factors associated with high PsAID-12 total scores (> 4) were explored using multivariable binary logistic regression. A culturally adapted Arabic PsAID-12 questionnaire was achieved with minor rephrasing. The validation study included 554 patients from 13 countries (mean age 45years, 59% females), with a mean PsAID score of 3.86 (SD 2.33). The Arabic PsAID-12 demonstrated excellent internal consistency (Cronbach's α = 0.95), and correlations with other measures ranged from 0.63 to 0.78. Test-retest reliability (N = 138 patients) was substantial (intraclass correlation coefficient, ICC 0.90 [0.86-0.93]; Cohen's kappa 0.80). Factors associated with a high PsAID score were disability (odds ratio, OR 3.15 [2.03-4.89]), depression (OR 1.56 [1.35-1.81]), widespread pain (OR 1.31 [1.12-1.53]), and disease activity (OR 1.29 [1.13-1.47]). Pain and fatigue were identified as the most impactful PsAID-12 domains for PsA patients. The Arabic PsAID is a valid and reliable measure that reflects the priorities of patients with PsA. PsAID scores correlated with disease activity and legacy outcome measures, as expected, indicating PsAID is a consistent measure of PsA impact across cultures. These findings highlight the potential of the Arabic PsAID in improving the care provided to Arabic-speaking patients worldwide.

Impact of Oral, Selective, Allosteric Tyrosine Kinase 2 Inhibitor, Deucravacitinib, on Psoriasis in Patients with Active Psoriatic Arthritis: Results from a Phase 2 Trial

Introduction: Deucravacitinib (DEUC), an oral, selective, allosteric tyrosine kinase 2 inhibitor, is approved in the US, EU, and other countries for treatment of adults with moderate-to-severe plaque psoriasis (PsO) who are candidates for systemic therapy. DEUC was superior to apremilast and placebo (PBO) in two phase 3 trials in patients with moderate to severe PsO. DEUC was efficacious on multiple measures of arthritis severity vs PBO in a phase 2 trial in patients with active psoriatic arthritis (PsA) who had ≥1 PsO lesion (≥2 cm). In patients with body surface area (BSA) involvement ≥3% at baseline (80% of patients in this trial), a greater proportion achieved PASI 75 with DEUC (6 mg QD: 42.4%, P=0.01; 12 mg QD: 59.6%, P&lt;0.0001) vs PBO (20.4%) at Week 16. This analysis evaluated the impact of DEUC on PsO in patients with PsA in the phase 2 trial (NCT03881059).&#x0D; Methods: The phase 2 double-blind PsA trial randomized patients (N=203) 1:1:1 to PBO, DEUC 6 mg once daily (QD), or DEUC 12 mg QD. After Week 16, patients could enroll in an optional, double-blind period until Week 52. DEUC-treated patients achieving minimal disease activity at Week 16 continued DEUC to Week 52. PsO disease activity measurements were assessed.&#x0D; Results: Baseline PsO characteristics were comparable across groups. At Week 16, significant decreases from baseline in mean PASI were observed with DEUC vs PBO in patients with baseline BSA ≥3%-&lt;10% or PASI ≤12 even with very low baseline PASI scores, and also in those with baseline BSA ≥10% and PASI &gt;12. Significant decreases in PASI from baseline were observed with DEUC vs PBO in patients with background csDMARD use (DEUC 6 mg, -4.0 and 12 mg, -4.9 vs PBO, -2.3; both P&lt;0.05) and those without csDMARD use (-3.7 and -4.0 vs -2.5, respectively; both P&lt;0.001). At Week 16, greater proportions of DEUC vs PBO patients achieved PASI ≤1 with baseline BSA ≥3% (DEUC 6 mg: 32.2%; DEUC 12 mg: 44.2%; PBO: 18.5%) and in patients with baseline BSA ≥10% and PASI &gt;12 (23.1%; 28.6%; 0.0%). In patients with baseline BSA ≥3%, decreases in mean PASI at Week 16 were maintained through Week 52 in patients continuing DEUC 6 mg (absolute PASI score, Week 16: 2.39, Week 52: 1.22) and 12 mg (Week 16: 0.64, Week 52: 0.24).&#x0D; Conclusion: DEUC significantly improved PsO in patients with PsA, regardless of baseline PsO severity and background csDMARD use. Improvement was comparable to that observed in the phase 3 POETYK PSO-1 trial.&#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D; &#x0D;

Is Active Synovitis of Metacarpophalangeal Joints a Neuropathic Condition in Rheumatoid Arthritis Patients? Results from an Ultrasound Study of Palmar Digital Nerves.

(1) Background: Rheumatoid arthritis (RA) is a chronic inflammatory joint disease, primarily characterized by pain. A significant proportion of patients report symptoms suggestive of neuropathic pain. The objectives of this study were to investigate the presence of an increased cross-sectional area (CSA) of the palmar digital nerves by ultrasound in patients with active synovitis of the metacarpophalangeal joints and to identify potential predictors of such an increase. (2) Methods: An ultrasound examination of the clinically most affected hand (from the second to the fifth metacarpophalangeal joint) was performed. The presence of synovitis was scored using a 0-3 semiquantitative method for each joint. The CSA of each pair of palmar digital nerves was measured. (3) Results: A significant correlation was found between the sum of the CSAs of the nerves and the Clinical Disease Activity Index (CDAI) (r = 0.387), as well as with the ultrasonographic grading of synovitis (r = 0.381) both at the patient and the joint level. These two variables, aimed at measuring disease activity, along with male gender, are the only predictors of the CSA of the palmar digital nerves. (4) Conclusions: Synovial inflammation of the metacarpophalangeal joints is, therefore, a condition that can influence the CSA of the palmar digital nerves and may partially explain neuropathic pain in patients with RA.

Longitudinal assessment of disease activity and muscle strength in juvenile dermatomyositis: a multicentre registry study.

To define disease activity measures, muscle strength and functional assessments in new-onset juvenile dermatomyositis (JDM) patients, at disease onset and follow up. A registry was set up in 18 hospitals, enrolling patients over 3-years (2015-2018). Clinical assessments were performed at baseline, and at 6, 12, 18 and 24 months after diagnosis. Disease Activity Score (DAS20), skin and musculoskeletal DAS sub-scales; Manual Muscle Test (MMT8); Childhood Myositis Assessment Scale (CMAS); Childhood Health Assessment Questionnaire disability index (CHAQ_DI 0-3) and 10 cm Visual Analog Scale (VAS) for overall wellbeing scores were compared by Poisson Model and Wald post-test for repeated measures. Ninety-six cases, being 61 (64%) females, median age 10 years had JDM diagnosis and 12 (13%) onset calcinosis. Mean ±SD scores at diagnosis and 6 months intervals for DAS20 (0-20) were 7.8±5, 6.3 ±4.8, 5±4, 4.9 ±5 and 0.5 ±2.3; with significant difference from baseline (p<0.01). Skin DAS subscales were 2.8±3.3, 1.8±2.9, 1,1±2.2, 0.6±1.8, 0.4±1.5. MMT (0-80) 62.6±20.4, 70.2±13.5, 73.3±11, 75.7±7.9 and 74.8±7.8, with significant difference from baseline up to 6 months (p=0.016); CMAS (0-53) 29.5±11.4, 33.1±8.3, 34.2±5.8, 34±6 and 33.3±5.4. CHAQ-DI (0-3) 1±0.9, 0.6±0.7, 0.8±0.8, 1±0.8 and 1±0.3; parents VAS 4.1±2.5, 2±2.1; 1.3±2.8, 4.1±3.1, 1.7±2.2. There was no significant difference for CMAS, CHAQ-DI and parents VAS from baseline up to 24-month assessment. DAS20 scores improved gradually during follow up, MMT8 improved significantly during the first 6 months and CMAS, CHAQ-DI and parents VAS scores had no significant improvement with persistent functional impairment over 2-years.

Food-Related Quality of Life and Its Predictors in Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) is associated with dietary restrictions and food- and drink-driven daily life limitations. Food-related quality of life (FR-QoL) is still an under-addressed issue in IBD. We aimed to study determinants of FR-QoL in an IBD cohort, namely objective measures of disease activity. A cross-sectional case-control study was conducted in a Tertiary Hospital, including adult patients with IBD (cases) and blood donors or subjects referred for colorectal polypectomies (controls). Participants answered an anonymous multimodal questionnaire including sociodemographic and clinical data, the validated FR-QoL-29, and the SIBDQ tools. Patients' disease activity was previously assessed by a physician using symptom-based scores and biomarkers (Harvey-Bradshaw index, partial Mayo score, fecal calprotectin). A total of 239 patients with IBD and 126 controls were included. Patients with active disease had poorer FR-QoL than patients in remission (80.0 [56.0-99.0] vs. 103.5 [81.0-129.9], p < 0.001). Still, patients with IBD had significantly lower FR-QoL compared with controls (99.0 [76.0-126.0] vs. 126.0 [102.8-143.0], p < 0.001), irrespective of disease activity. FR-QoL correlated with health-related quality of life, measured by SIBDQ (r = 0.490, p < 0.001), and was significantly impaired by patients' depressive humor (84.0 [61.0-112.0] vs. 108.0 [88.0-130.5], p < 0.001). Globally, FR-QoL compromise was mostly related to persistent worries about food, concerns about food-related symptoms, and life disruption due to eating and drinking. Patients with IBD showed significant FR-QoL impairment, irrespective of disease type and activity. Related psychosocial factors, such as the patient's affective status and fear around eating, warrant a need for a multidisciplinary approach to IBD, including tailored nutritional counseling.

Methotrexate treatment strategies for rheumatoid arthritis: a scoping review on doses and administration routes

BackgroundTo describe the evidence of methotrexate (MTX) initiation strategies in patients with rheumatoid arthritis (RA) and, in the case of non-responders, analyse the efficacy and safety of route and dose optimisation.MethodsWe conducted a comprehensive scoping review of randomised controlled trials according to PRISMA Scoping Reviews Checklist and the framework proposed by Arksey and O’Malley. PubMed, EMBASE, and Cochrane were searched without language restriction, and hand searches of relevant articles were examined.ResultsWe identified 1,367 potentially eligible studies, of which 12 were selected based on the titles and abstracts and then on the full-length articles. In naïve-MTX patients, a linear dose-response relationship for starting dose was found between 5 mg/m2/week (7.5–10 mg/week) and 10 mg/m2/week (15–22 mg/week), without toxicity correlation. A higher initial dose of MTX (25 mg vs. 15 mg) was more effective, resulting in fewer dose increases due to ineffectiveness and more dose reductions due to higher remission rates. There was also a trend towards increased gastrointestinal toxicity. Comparing different routes of administration of MTX, subcutaneous MTX showed a statistically higher ACR20 response (85%) in comparison with oral MTX (77%) (p < 0.05). The clinical efficacy and safety of accelerated and conventional start MTX regimens were comparable between 7.5 and 15 mg with a 2,5 mg dose increase every two weeks. In RA patients who have failed the initial treatment with MTX, the stepwise increase in MTX doses is associated with a higher ACR20 response and sustained remission rate than other strategies. In MTX non-responders, optimisation to SC MTX was associated with improvements in ACR20 and ACR50 rates with similar toxicity between groups. In the early RA patients subgroup, SC MTX showed higher ACR20 response rates than oral MTX, and intensive oral methods have a much higher sustained remission rate, shorter mean time to remission, and better clinical disease activity measures than conventional treatments.ConclusionsHigher starting doses of MTX and initial subcutaneous MTX made better performance in improving the ACR20 response, although the clinical effectiveness and safety of other MTX start regimens are comparable. This scoping review provides evidence in support of optimising MTX treatment in terms of route and dose prior to concluding that MTX treatment in RA patients has failed.

Long-term efficacy of a 2-year MRI treat-to-target strategy on disease activity and radiographic progression in patients with rheumatoid arthritis in clinical remission: 5-year follow-up of the IMAGINE-RA randomised trial

ObjectiveTo investigate whether a 2-year MRI treat-to-target strategy targeting the absence of osteitis combined with clinical remission, compared with a conventional treat-to-target strategy targeting clinical remission only (IMAGINE-rheumatoid arthritis (RA)...

Hormonal Contraceptives Reduce Active Symptomatic Disease but May Increase Intestinal Inflammation in IBD.

Among women of reproductive age with inflammatory bowel disease (IBD), we aimed to assess the relationship of hormonal contraceptives (HCs) with IBD-related symptoms, and intestinal inflammation. A nested cohort of women in the longitudinal Manitoba Living with IBD Study, ages 18 to 49, were followed for 1 year, with bi-weekly online surveys. This included a validated measure of disease activity; IBD Symptom Inventory (IBDSI), and stool samples obtained at 3 time-points for assessment of fecal calprotectin (FCAL). Use of HC included oral and vaginal intrauterine devices. Logistic regression analysis was used to assess the association between HC and IBD-related symptoms (IBDSI>14 for Crohn disease, >13 for ulcerative colitis), or inflammation (FCAL>250ug/g) at any measurement point in the study. Of 71 women, 17 (24%) reported taking HC in the 1 year period. Adjusting for age, disease type, disease duration, and smoking status, the odds of having increased IBD-related symptoms (IBDSI) during the year were lower for women using HC compared with women not using HC [adjusted odds ratio 0.16, 95% CI, 0.02-0.90]. Conversely, women using HC were more likely to have inflammation during the year [adjusted odds ratio 5.7, 95% CI, 1.23-43.6]. HC use among women with IBD was associated with a lower likelihood of IBD-related symptoms but a higher likelihood of experiencing intestinal inflammation (FCAL>250ug/g) over 1 year. Further work is needed to examine this dichotomous result, potentially examining aspects such as duration of HC use, and the types of HC.

ALOX5 drives the pyroptosis of CD4+ T cells and tissue inflammation in rheumatoid arthritis.

Pyroptosis, an inflammatory form of programmed cell death, is linked to the pathology of rheumatoid arthritis (RA). Here, we investigated the molecular mechanism underlying pyroptosis in T cells isolated from patients with RA. Compared with healthy individuals, patients with RA had more pyroptotic CD4+ T cells in blood and synovia, which correlated with clinical measures of disease activity. Moreover, the mRNA expression and protein abundance of arachidonate 5-lipoxygenase (ALOX5), which converts arachidonic acid to leukotriene A4 (LTA4), were increased in CD4+ T cells from patients with RA and, among patients with RA, were lowest in those in clinical remission. Knockdown or pharmacological inhibition of ALOX5 suppressed CD4+ T cell pyroptosis and improved symptoms in two rodent models of RA. Mechanistically, the increase in ALOX5 activity in RA CD4+ T cells enhanced the production of the LTA4 derivative LTB4, which stimulated Ca2+ influx through ORAI3 channels, leading to the activation of NLRP3 inflammasomes and pyroptosis. Our findings reveal a role for ALOX5 in RA and provide a molecular basis for further exploring the clinical utility of ALOX5 inhibition in RA and for using ALOX5 as a biomarker to distinguish active disease and remission in RA.

Pain is Common in Myositis and Associated with Disease Activity.

Understanding pain in myositis remains challenging. This study aimed to assess patient-reported pain and its correlation with myositis core set measures (CSMs), patient-reported outcomes (PROs), and functional measures. Fifty subjects underwent baseline, 3-month, and 6-month assessments, evaluating myositis CSMs, functional measures, and patient-reported outcomes. Pain was measured using three methods: (1) a 10-cm Visual Analogue Scale (VAS), (2) pain score from the HAQ-DI, and (3) SF-36 (Short Form survey) pain questions. Correlations between disease activity measures and pain were examined at baseline, and changes in both were assessed at 6 months, along with longitudinal change of pain. The change in pain was also correlated with the published 2016 ACR/EULAR myositis response criteria, physician/patient's assessment of change. Nearly half of patients (45%) reported moderate to severe pain in all 3 pain scales, with higher severity of pain in PM/NM subset. At baseline, pain severity showed a strong correlation with most CSMs, PROs and functional outcomes in all the 3 pain scales and similar trends were noted for change in pain at the 6 months. On longitudinal analysis, the physical function scores and fatigue showed strong correlation with pain. Pain improved in myositis patients with improvement in disease activity over time. Pain is common in myositis and is associated with multiple measures of disease activity, PROs, and functional outcomes in myositis. Most importantly pain improves with improvement in disease activity. SF-36 pain questions have good psychometric properties.

How to Monitor Disease Activity of Axial Spondyloarthritis in Clinical Practice.

Treatment guided by periodic and quantitative data assessment results in better outcomes compared to using clinical gestalt. While validated generic as well as specific disease activity measures for axial spondyloarthritis (axSpA) are available, there is vast scope to improve their actual utilization in routine clinical practice. In this review, we discuss available disease activity measures for axSpA, describe results from the survey conducted among general rheumatologists as well as Spondyloarthritis Research and Treatment Network (SPARTAN) members about disease activity measurement in daily practice, and discuss ways to improve axSpA disease activity using technological advances. We also discuss the definitions of active disease and target for the treatment of axSpA. The 2019 American College of Rheumatology (ACR)/Spondylitis Association of America (SAA)/Spondyloarthritis Research and Treatment Network (SPARTAN) axSpA treatment guidelines conditionally recommend the regular monitoring of disease activity using a validated measure such as Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) or Ankylosing Spondylitis Disease Severity Index (ASDAS). Assessment of Spondyloarthritis International Society (ASAS)-European Alliance of Associations for Rheumatology (EULAR) guidelines recommend ASDAS as the most appropriate instrument for the assessment of disease activity, preferably calculated using C-reactive protein (CRP). ASAS has selected a core set of variables which were updated recently and have been endorsed by the Outcome Measures in Rheumatology Clinical Trials (OMERACT) group in order to bring homogeneity in assessment of axSpA. In a recent study, Patient-Reported Outcomes Measurement Information System (PROMIS®) measures were able to discriminate inactive, moderate, and high-very high ASDAS activity groups. A newly developed semi-objective index P4 (pain, physical function, patient global, and physician global) correlates well with BASDAI and ASDAS in axSpA and can also be used for other rheumatic diseases in busy clinical practices. Regular disease activity monitoring is critical for long-term management of axSpA and shared decision-making. The integration of electronic health records and smart devices provides a great opportunity to capture patient-reported data. Automated capture of electronic patient-reported outcome measures (ePROMs) is a highly efficient way and results in consistent regular monitoring and may improve the long-term outcomes. While currently used measures focus only on musculoskeletal symptoms of axSpA, a composite disease activity measure that can also incorporate extra-articular manifestations may provide a better assessment of disease activity.

Development of a novel clinimetric tool: PAtient Reported Disease Activity Index in Rheumatoid Arthritis (PARDAI-RA) by PANLAR, for the assessment of patients living with rheumatoid arthritis.

Clinical experience has shown that a single measure is not sufficient to assess disease activity in rheumatoid arthritis (RA). Various clinimetric tools are necessary to address the many clinical situations that can arise. In order to develop a comprehensive measurement tool, the Pan American League of Associations for Rheumatology searched for the most frequent measures of disease activity applied in RA by means of a semi-systematic review of the available literature. We found that the most frequently reported measures of disease activity were the 28-joint Disease Activity Score, C-reactive protein, and the erythrocyte sedimentation rate, followed by patient-reported measures of pain and stiffness and many other composite indices and patient-reported outcome measures. The most frequent physician-reported sign of disease was the swollen joint count, and the most frequently self-reported feature was the increase in disease activity or flares. In this article, we present a new clinimetric tool developed based on expert consensus and on data retrieved from our search. Disease activity can be better assessed by combining various data sources, such as clinical, laboratory, and self-reported outcomes. These variables were included in our novel clinimetric tool. Key Points • The goal of treatment of RA is to achieve the best possible control of inflammation, or even remission; therefore, disease management should include systematic and regular evaluation of inflammation and health status. • Clinimetric tools evaluate a series of variables (e.g., symptoms, functional capacity, disease severity, quality of life, disease progression) and can reveal substantial prognostic and therapeutic differences between patients. • Our clinimetric tool, which is based on a combination of data (e.g., clinical variables, laboratory results, PROMs), can play a relevant role in patient assessment and care.

Safety and Efficacy of Various Doses of Tofacitinib among Patients with Active Seronegative Spondyloarthritides – A Retrospective Observational Study

Introduction: Seronegative spondyloarthritides (SpA) are a family of various joint disorders that classically include ankylosing spondylitis (AS), psoriatic arthritis (PsA), inflammatory bowel disease (IBD) associated arthritis, reactive arthritis (formerly Reiter syndrome; ReA), and undifferentiated SpA. Treatment goals for SpA are reducing symptoms, decreasing complications associated with the disease, and reducing functional limitations. Aim of the study: The purpose of this study is to find efficacy and safety of various doses of Tofacitinib, an oral Janus kinase inhibitor, compared with placebo in different stages of the treatment in patients with active Seronegative Spondyloarthritides. Methods: This retrospective observational study was carried out in the Popular Medical College Hospital, Bangladesh.
