Abstract
INTRODUCTION Biological disease-modifying antirheumatic drugs (bDMARD) have improved the clinical course and quality of life of patients with rheumatoid arthritis (RA). However, some patients failed to respond or have an insufficient response to bDMARD early in the course of the treatment. OBJECTIVES To determine the percentage of RA patients who need to switch due to ineffectiveness in the first year of treatment and to identify specific baseline features as possible predictors of switch due to ineffectiveness in the first year of treatment. MATERIALS AND METHODS An observational retrospective study was conducted with patients with RA that started their first bDMARD. Demographic data, disease characteristics, disease activity data scores, laboratory parameters and treatment at baseline were collected. The proportion of patients who failed to respond and who switched to another bDMARD in the first year of treatment was calculated. RESULTS A total of 437 (364 females, 83.3%) patients with RA were included. The majority of these patients started an anti-TNF-α agent (n=315, 72.1%). Forty-eight (11.0%) patients failed to respond to the bDMARD in the first year of treatment. There were significantly more current or former smokers (p=0.030), with a history of depression (p=0.003) and positive for RF at baseline (p=0.014) in the switch group. In the multivariate analysis, anti-TNF-α agents use (OR 8.3, 95% CI 2.4-28.8, p=0.001), tobacco exposure (OR 2.3, 95% CI 1.1-4.8, p=0.02) and history of depression (OR 3.1, 95% CI 1.3-7.7) seem to predict the need to switch in the first year of treatment due to ineffectiveness. DISCUSSION AND CONCLUSION In our study, tobacco exposure and depression appear to be modifiable risk factors associated with early switching due to ineffectiveness. Addressing these factors in daily clinical practice is crucial to enhance the overall response to therapy and improve the well-being of patients.

Abstract
Biologic therapy involving anti-tumor necrosis factor-α (anti-TNFα) agents has fundamentally changed the management of patients with immune-mediated inflammatory diseases, including rheumatoid arthritis, thus benefiting many patients. Nevertheless, the inability of some patients to achieve low disease activity or clinical remission remains a major concern. To address such concerns, next-generation anti-TNFα agents that differ from the immunoglobulin G-format anti-TNFα agents that have been used to date are being developed using antibody-engineering technology. Their unique design employing novel molecular characteristics affords several advantages, such as early improvement of clinical symptoms, optimization of drug bioavailability, enhancement of tissue penetration, and a reduction in side effects. This holds promise for a new paradigm shift in biologic therapy via the use of next-generation anti-TNFα agents. Ozoralizumab, a next-generation anti-TNFα agent that was recently approved in Japan, comprises a variable region heavy-chain format. It has a completely different structure from conventional therapeutic antibodies, such as a small molecular size, an albumin-binding module, and a unique format that produces an avidity effect. Ozoralizumab exhibited rapid biodistribution into joints, provided attenuation of Fcγ receptor-mediated inflammatory responses, and had a high binding affinity to TNFα in non-clinical studies. In clinical trials, ozoralizumab yielded an early improvement in clinical symptoms, a sustained efficacy for up to 52 weeks, and an acceptable tolerability in patients with rheumatoid arthritis. This review focuses on the results of pre-clinical and clinical trials for ozoralizumab and outlines the progress in next-generation antibody development.

Rheumatoid factor titers, but not Fc fragments, may be strongly associated with drug survival of anti-TNF agents in patients with rheumatoid arthritis. North Clin Istanb 2024; 11:147-157. [PMID: 38757098 PMCID: PMC11095329 DOI: 10.14744/nci.2023.01643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 03/27/2023] [Accepted: 04/24/2023] [Indexed: 05/18/2024] Open
Abstract
OBJECTIVE To investigate the effects of both the Fc fragment in tumor necrosis factor (TNF) inhibitors and rheumatoid factor (RF) titers on treatment survival, disease activity, and laboratory parameters in patients with rheumatoid arthritis (RA). METHODS In this retrospective cohort study, patients with RA who had started any anti-TNF therapy between January 2017 and March 2020 and who had stayed on this treatment for at least six months were included. The data of the patients were compared separately according to continuation or discontinuation of treatment and the presence or absence of Fc portion in the structure of anti-TNFs. Patients who were taking certolizumab pegol (CZP) without the Fc fragment were placed in the "without Fc group" (wo/Fc), while patients who were taking other drugs (adalimumab, etanercept, golimumab, and infliximab) were placed in the "with Fc group" (w/Fc). RESULTS Among the 221 RA patients whose data were available, 52 patients met the inclusion criteria and were included in the study. There was a significant difference in the DAS28-CRP score between wo/Fc group and w/Fc group in the third month of treatment (p=0.012). However, this difference did not persist at the sixth month of treatment (p=0.384). According to the cox-regression results, RF titers were determined to have a significant impact on the drug survival of anti-TNF agents when adjustments were made for the effects of other candidate predictors (Hazard ratio: 1.007 (1.002-1.012), p=0.009). CONCLUSION Our results suggest that compared to the Fc fragment, RF titers were the more important risk factor in survival of anti-TNF drugs.

ACR Open Rheumatol 2024; 6:81-90. [PMID: 38058274 PMCID: PMC10867292 DOI: 10.1002/acr2.11630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Revised: 10/13/2023] [Accepted: 10/20/2023] [Indexed: 12/08/2023] Open
Abstract
BACKGROUND Given that autoantibodies to peptidylarginine deiminase 4 (PAD4) are associated with erosive disease in established rheumatoid arthritis (RA), this study was conducted to compare the clinical and prognostic use of anti-PAD4 antibodies in patients with early and established RA. METHODS Sera from patients with early (duration <2 years; n = 422) or established (duration ≥2 years; n = 359) RA from two randomized clinical trials of tofacitinib ± methotrexate compared with adalimumab + MTX or MTX alone were evaluated for the presence of anti-PAD4 and anti-PAD3/4 antibodies at baseline and posttreatment time points. Summary statistics were calculated for demographic, clinical, and serological characteristics, and generalized estimating equations were used to model clinical outcomes by disease duration according to anti-PAD4 status. RESULTS Anti-PAD4 antibodies were present in 22% and 40% of patients with early and established RA, respectively, stable following treatment, and associated with baseline joint damage only in established RA. In early RA, baseline anti-PAD4 antibodies were associated with a greater improvement in disease activity score 28-joint count using C-reactive protein levels after treatment compared with individuals with negative anti-PAD4 (P = 0.049). Tofacitinib ± MTX was more broadly efficacious than MTX alone at improving clinical outcomes in early and established RA, irrespective of anti-PAD4 status (P < 0.05 for all), whereas adalimumab + MTX exhibited differential benefits in achieving disease activity score remission in early RA (P = 0.036) and American College of Rheumatology 20 responses in established RA (P = 0.002). CONCLUSION Differences in prevalence, clinical associations, and treatment-response outcomes according to anti-PAD4 antibody status in early and established RA suggests the existence of a therapeutic window to prevent the accumulation of irreversible joint damage in early patients with RA with anti-PAD4 antibodies.

Abstract
OBJECTIVE Wound healing of oral traumatic ulcers (OTU) is strongly associated with cytokines and inflammatory cells, and the reduction of anti-inflammatory cells, such as lymphocyte B, may interfere with OTU repair. We aimed to evaluate the role of CD20 + cells in the healing process of OTU in rats. DESIGN Wistar male rats were divided into four groups: a control group (treated with 0.1 mL/kg of saline) and three groups treated with anti-CD20 rituximab (RTX) at 2.5, 10, or 40 mg/kg 24 h before OTU production. The animals were weighed (day 0) and euthanized on days 3, 7, 14, and 21 after ulceration. With Blood cells (hematological analysis) and the traumatically induced ulcers were clinically measured. The mucosal samples were histologically (scores 0-4), histochemically (collagen assay (picrosirius)), histomorphometrically (cell counting), and immunohistochemically (CD20+, Tumor Necrosis Factor alpha(TNF-α), Interleukin(IL)- 1β, IL-6 and α-smooth-muscle-actin (α-SMA)) analyzed. ANOVA-1-2-way/Bonferroni, Kruskal-Wallis/Dunn, and correlation analyses were performed (GraphPad Prism 5.0, p < 0.05). RESULTS RTX leads to leukopenia, lymphocytopenia, and neutropenia (p < 0.001), and high doses reduced the OTU area (p = 0.001), impaired histologic scores (p < 0.05), and delayed polymorphonuclear (p < 0.001) and mononuclear (p < 0.001) cells, and total (p = 0.011), type-I (p = 0.008), and type-III (p = 0.021) collagen. CONCLUSION RTX treatment reduced CD20+ cells in OTU (p = 0.001), TNF-α (p = 0.006), and α-SMA (p = 0.022) immunostaining and delayed IL-6 reduction (p = 0.006), with no influence in IL-1β immunostaining. CD20 + cell blockage by RTX reduced cell migration, acute inflammation, and wound healing in OTU.

Abstract
Optimized animal models and effective imaging techniques are exceedingly important to study cranial defects in bone loss due to chronic inflammation. In this study, the assessment procedure on a zebrafish inflammation-type skull defects model was monitored in vivo with spectral-domain optical coherence tomography (SD-OCT), and the efficacy of etidronate disodium in bone regeneration was assessed. An acute skull defect injury model was established in adult zebrafish using a stereotaxic craniotomy device. SD-OCT imaging was performed immediately following the mechanical injury. Both SD-OCT and immunohistochemistry results demonstrated an increase in inflammation-induced skull destruction within 5 days, which was confirmed by pathological experiments.

Abstract
A 2021 study described the development and validation of a blood-based precision medicine test called the molecular signature response classifier (MSRC) that uses 23 features to identify rheumatoid arthritis (RA) patients who are likely nonresponders to tumor necrosis factor-α inhibitor (TNFi) therapy. Both the gene expression features and clinical components (sex, body mass index, patient global assessment, and anti-cyclic citrullinated protein) included in the MSRC were statistically significant contributors to MSRC results. In response to continued inquiries on this topic, we write this letter to provide additional insights into the contribution of clinical components to the MSRC on the Network-004 validation cohort.

Abstract
BACKGROUND Clinical remission is the goal in rheumatoid arthritis (RA) management; however, this can be difficult to achieve in several parts of the world. Our objective was to determine predictors of remission and remission/low disease activity (LDA) in RA. METHODS A longitudinal real-setting RA cohort was followed up (January 2016-2020). Predictors examined were sex, age at diagnosis, disease duration, socioeconomic status, tobacco use, rheumatoid factor titer, comorbidities (Charlson index), Simple Disease Activity Index (SDAI) score, disability (Multidimensional Disease Health Assessment Questionnaire), health-related quality of life (Short Form-36 questionnaire), glucocorticoid dose, biological/target synthetic disease-modifying antirheumatic drugs, and conventional DMARD (c-DMARD) use. Univariable and multivariable generalized estimating equation models were done to determine predictors of remission (at a given visit) and sustained remission (2 consecutives visits), using the SDAI definition (0 or <3.3). Similarly, remission/LDA (SDAI <11) predictors were examined. RESULTS Five hundred thirty RA patients included the following: 160 patients (30.2%) achieved remission in at least 1 visit, and 126 patients (23.77%) achieved sustained remission. On the multivariable analysis glucocorticoid dose (odds ratio [OR], 1.060; 95% confidence interval [CI], 1.027-1.094; p = 0.004) and current (OR, 2.293; 95% CI, 1.811-2.903; p < 0.001) or past (OR, 1.383; 95% CI, 1.127-1.698; p = 0.002) use of c-DMARDs predicted remission/LDA in at least 1 visit, whereas the SDAI (OR, 0.951; 95% CI, 0.942-0.959; p < 0.001), Multidimensional Disease Health Assessment Questionnaire (OR, 0.648; 95% CI, 0.549-0.764; p < 0.001), and age at diagnosis (OR, 0.994; 95% CI, 0.990-0.998; p = 0.004) were negative predictors. As to sustained remission/LDA, current (OR, 2.012; 95% CI, 1.458-2.776: p < 0.001) or past (OR, 1.517; 95% CI, 1.155-1.993; p = 0.003) use of c-DMARDs, having a better Short Form-36 questionnaire physical component summary (OR, 1.022; 95% CI, 1.014-1.029; p < 0.001), and older age at diagnosis (OR, 1.013; 95% CI, 1.003-1.022; p = 0.008) predicted it, whereas SDAI (OR, 0.949; 95% CI, 0.933-0.965; p < 0.001) and medium low/low socioeconomic status (OR, 0.674; 95% CI, 0.500-0.909; p = 0.010) were negative predictors. CONCLUSION During follow-up of this real-world RA cohort, c-DMARD use predicted remission and remission/LDA. In contrast, disease activity was a negative predictor.

Abstract
Oral traumatic ulcers (OTU) are common in dental routine, and the control of proinflammatory cytokines, such as the tumor necrosis factor-alpha (TNF-α), may interfere with OTU repair. Our aim was to evaluate the role of TNF-α in the healing process of OTU in rats. Wistar male rats were divided into six groups: a control-group (treated with 0.1 mL/kg of saline) and five groups treated with anti-TNF-α infliximab (INF) at 1, 3, 5, 7, and 10 mg/kg immediately before OTU production. The animals were weighed (day 0) and euthanized on days 1, 3, 7, 14 and 21 after ulceration. The ulcers were clinically measured, and the mucosa samples were histologically (scores 0-4), histochemically (collagen assay (pircrosirius)), histomorphometrically (cell counting), and immunohistochemically (TNF-α, α-smooth-muscle-actin (α-SMA), monocyte-chemoattractive-protein-1 (MCP-1), interleukin-8 (IL-8), and fibroblast-growth-factor (FGF)) analyzed. The Evans blue assay was used to measure the vascular permeability. ANOVA-1-2-way/Bonferroni, Kruskal-Wallis/Dunn, and correlation analyses were performed (GraphPad Prism 5.0, p < 0.05). High doses of INF reduced the OTU area (p = 0.043), body mass loss (p = 0.023), vascular permeability (p < 0.001), and reduced delayed histologic scores (p < 0.05), polymorphonuclear (p < 0.001) and mononuclear (p < 0.001) cells, blood vessel counting (p = 0.006), and total (p < 0.001), type-I (p = 0.018), and type-III (p < 0.001) collagen. INF treatment reduced TNF-α immunostaining and delayed MPC-1, FGF, and α-SMA expression, with little/none influence in IL-8 immunostaining. TNF-α blockage by INF reduced acute inflammation in OTU but delayed cell migration and wound healing.

Abstract
OBJECTIVE Rheumatoid arthritis (RA) is more common in females, and although the cause of RA is unknown, it is characterized by the production of autoantibodies. The aims of this study were to determine whether RA-associated autoantibodies are more often found in females than males and to identify factors that influence the relationship between sex and seropositivity. METHODS Databases were searched and studies of RA (N ≥ 100) were included if they reported proportion of seropositive patients with RA by sex. Metaanalyses and metaregression were conducted using the random-effects model. Covariates regressed were smoking, age, BMI, Health Assessment Questionnaire-Disability Index (HAQ-DI), and the Disease Activity Score in 28 joints (DAS28). RESULTS Eighty-four studies with a total of 141,381 subjects with rheumatoid factor (RF) seropositivity and 95,749 subjects with anticitrullinated protein antibody (ACPA) seropositivity met inclusion criteria. The mean age of participants ranged from 37 to 68 years and the proportion of female subjects ranged from 9% to 92%. Results indicated that females were less likely than males to be seropositive: odds ratio (OR) 0.84 [95% CI 0.77-0.91] for RF and OR 0.88 [95% CI 0.81-0.95] for ACPA. BMI, smoking, mean age, DAS28, and HAQ-DI did not affect the relationship between sex and seropositivity. CONCLUSION Although studies report that females have higher RA disease activity than males and that seropositivity predicts worse outcomes, females were less likely to be seropositive than males.

Differential efficacy of TNF inhibitors with or without the immunoglobulin fragment crystallizable (Fc) portion in rheumatoid arthritis: the ANSWER cohort study. Rheumatol Int 2022; 42:1227-1234.

Abstract
Rheumatoid factor (RF) binds to the fragment crystallizable (Fc) portion of immunoglobulin. It could bind to the Fc portion of anti-TNF inhibitors (TNFi) and attenuate the clinical efficacy. We tried to determine whether the therapeutic efficacy of TNFi with Fc might be lower than that of TNFi without Fc in rheumatoid arthritis (RA) patients with high titres of RF. The Kansai Consortium for Well-being of Rheumatic Disease Patients (ANSWER) cohort is an observational multi-center registry of patients with RA in the Kansai district of Japan. RA patients treated with TNFi were included and divided into two groups based on the structural characteristics between TNFi with Fc (infliximab, adalimumab, golimumab, and etanercept) and TNFi without Fc (certolizumab pegol). Patients were classified into 4 groups according to RF titre quartiles. The sequential disease activity score in 28 joints using erythrocyte sedimentation rate (DAS28-ESR) was compared by Mann-Whitney U test between TNFi with and without Fc in each RF titre group. Multiple linear regression analysis was used to analyze the effect of TNFi without Fc for the change of DAS28-ESR adjusted after potential confounders. A total of 705 RA patients were classified into four groups (RF1; RF 0-15.0 IU/mL, RF2; 15.0-55.0, RF3; 55.0-166, RF4; 166-7555). In RF4, RA patients treated with TNFi without Fc had a significantly lower DAS28-ESR than those treated with TNFi with Fc [3.2 (2.3-4.2) vs. 2.7 (2.0-3.0)] after 12 months. This effect of TNFi without Fc for the change of DAS28-ESR after 12 months treatment retained in multivariate analysis in RF4. TNFi without Fc may be more efficacious than TNFi with Fc in RA patients with high RF titres.

Therapeutic Potential of a Novel Bifidobacterium Identified Through Microbiome Profiling of RA Patients With Different RF Levels. Front Immunol 2021; 12:736196. [PMID: 34867956 PMCID: PMC8634832 DOI: 10.3389/fimmu.2021.736196] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Accepted: 10/08/2021] [Indexed: 02/01/2023] Open
Abstract
The potential therapeutic effects of probiotic bacteria in rheumatoid arthritis (RA) remain controversial. Thus, this study aimed to discover potential therapeutic bacteria based on the relationship between the gut microbiome and rheumatoid factor (RF) in RA. Bacterial genomic DNA was extracted from the fecal samples of 93 RA patients and 16 healthy subjects. Microbiota profiling was conducted through 16S rRNA sequencing and bioinformatics analyses. The effects of Bifidobacterium strains on human peripheral blood mononuclear cells and collagen-induced arthritis (CIA) mice were assessed. Significant differences in gut microbiota composition were observed in patients with different RF levels. The relative abundance of Bifidobacterium and Collinsella was lower in RF-high than in RF-low and RF-negative RA patients, while the relative abundance of Clostridium of Ruminococcaceae family was higher in RF-high than in RF-low and RF-negative patients. Among 10 differentially abundant Bifidobacterium, B. longum RAPO exhibited the strongest ability to inhibit IL-17 secretion. Oral administration of B. longum RAPO in CIA mice, obese CIA, and humanized avatar model significantly reduced RA incidence, arthritis score, inflammation, bone damage, cartilage damage, Th17 cells, and inflammatory cytokine secretion. Additionally, B. longum RAPO significantly inhibited Th17 cells and Th17-related genes—IL-17A, IRF4, RORC, IL-21, and IL-23R—in the PBMCs of rheumatoid arthritis patients. Our findings suggest that B. longum RAPO may alleviate RA by inhibiting the production of IL-17 and other proinflammatory mediators. The safety and efficacy of B. longum RAPO in patients with RA and other autoimmune disorders merit further investigation.

Abstract
Introduction Rheumatoid arthritis (RA) is one of the most commonly encountered autoimmune diseases. Treatment generally includes disease-modifying anti-rheumatic drugs (DMARDs) and/or biological therapy. However, a significant proportion of the patients do not respond to treatment either as a (primary failure) or lose efficacy over time (secondary failure). Several factors are assumed to influence these conditions. Objectives To estimate the prevalence of failure of biological therapy in patients with RA and its causes. Methods A total of 335 RA patients who were diagnosed at a tertiary center in Jeddah, Saudi Arabia, and had a failure after receiving biological therapy were included in this study. Several variables were considered; patient’s socio-demographic data, comorbid conditions, types of biological therapy, the duration of using biological therapy in months, number of biological therapies, allergic reactions, disease activity, and treatment duration. Results Overall the prevalence of failure to biological therapy was 58%; 77% primary failure and 23% secondary failure. Patients with negative rheumatoid factor (RF) (p=0.006), using low-dose steroids, and with a longer disease duration had a significant failure of biological therapy (p=0.023). Conclusion A high percentage of RA patients had a failure of biological therapy. A multicentric trial is recommended to look for additional factors.

Prevalence and relevant factors of positive RF in brucellosis patients with arthralgia. PLoS Negl Trop Dis 2021; 15:e0009749. [PMID: 34543280 PMCID: PMC8452007 DOI: 10.1371/journal.pntd.0009749] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2020] [Accepted: 08/22/2021] [Indexed: 02/03/2023] Open
Abstract
Background Brucellosis is a critical zoonotic disease in the world, it is the non-specific arthralgia that make brucellosis patients easily misdiagnosed as rheumatoid arthritis (RA) in endemic regions. Elevated rheumatoid factor (RF) is an essential indicator of RA, and the RF in brucellosis patients is significantly higher than healthy people. Therefore, this study further explored the distribution of RF and the relevant factors of the RF positivity in brucellosis patients with arthralgia, in order to strengthen the recognition of physicians for brucellosis patients with RF positivity, especially in brucellosis-endemic areas, so as to avoid misdiagnosis and untimely treatment that may lead to malignant outcomes. Methodology and principal findings The medical records of all 572 brucellosis inpatients were collected in the Sixth People’s Hospital of Shenyang, China from 2015 to 2016. After excluding 106 patients without arthralgia, 5 patients who unwilling to perform RF testing and 16 patients with diseases that may affect RF, 445 brucellosis inpatients with arthralgia were involved in this retrospective cross-sectional study. 143 (32.1%) patients with RF >10 IU/ml were classified into the RF positive group, with an average level of 16.5[12.2, 34.7] IU/ml, of which 45 (10.1%) patients were high-positive with RF >30 IU/ml. Multivariate logistic regression model was used to further analyze the relevant factors of the RF positivity and found that age, wrist joint pain and elevated C-reactive protein (CRP) were positively associated with RF positivity, with OR of 1.02 (P = 0.024), 8.94 (P = 0.008) and 1.79 (P = 0.019), respectively. Conclusion The prevalence of positive RF in brucellosis patients with arthralgia was critical, nearly one-third of patients had RF positive. Elderly men brucellosis patients with arthralgia, wrist joint pain and elevated CRP were at high risk of positive RF. It is reminded that physicians should focus on differential diagnosis during clinical diagnosis and treatment, especially in brucellosis-endemic regions. Brucellosis is a highly contagious zoonosis caused by Brucella spp., which compromises to organs and systems, causing non-specific symptoms such as fever, headache, sweating, fatigue, myalgia and arthralgia. Similarly, patients with rheumatoid arthritis (RA) may also have the above non-specific symptoms. It is precisely because of the non-specificity and similarity of symptoms that brucellosis patients were easily misdiagnosed and failed to receive timely treatment, resulting in neurosis, chronic fatigue syndrome, endocarditis and other adverse outcomes. However, rheumatoid factor (RF) is an essential indicator of RA, and the RF in brucellosis patients is significantly higher than healthy people. In order to strengthen the recognition of physicians for brucellosis patients with RF positivity, we conducted this research and found that the prevalence of positive RF in brucellosis patients with arthralgia was common and critical. Elderly men brucellosis patients with arthralgia, wrist joint pain and elevated CRP were at high risk of positive RF. It is reminded that physicians should pay attention to the possibility of brucellosis during clinical diagnosis and treatment, especially in brucellosis-endemic regions, which had certain clinical significance.

ACPA Status Correlates with Differential Immune Profile in Patients with Rheumatoid Arthritis. Cells 2021; 10:cells10030647.

Abstract
Rheumatoid arthritis (RA) is a progressive erosive autoimmune disease that affects 1% of the world population. Anti-citrullinated protein autoantibodies (ACPA) are routinely used for the diagnosis of RA, however 20–30% of patients are ACPA negative. ACPA status is a delineator of RA disease endotypes with similar clinical manifestation but potentially different pathophysiology. Profiling of key peripheral blood and synovial tissue immune populations including B cells, T follicular helper (Tfh) cells and CD4 T cell proinflammatory cytokine responses could elucidate the underlying immunological mechanisms involved and inform a treat to target approach for both ACPA-positive and ACPA-negative RA. Detailed high dimensionality flow cytometric analysis with supervised and unsupervised algorithm analysis revealed unique RA patient peripheral blood B cell and Tfh cell profiles. Synovial tissue single cell analysis of B cell subpopulation distribution was similar between ACPA− and ACPA+ RA patients, highlighting a key role for specific B cell subsets in both disease endotypes. Interestingly, synovial tissue single cell analysis of CD4 T cell proinflammatory cytokine production was markedly different between ACPA− and APCA+ RA patients. RNAseq analysis of RA patient synovial tissue highlighted disease endotype specific gene signatures. ACPA status associates with unique immune profile signatures that reinforce the need for a treat to target approach for both endotypes of RA.

Abstract
Background/aim To assess the real-life efficacy, retention rate, and safety data of tofacitinib in rheumatoid arthritis (RA) patients. Materials and methods We analyzed all patients registered in the HURBİO database who received at least 1 dose of tofacitinib. Patients who received at least one dose were included in retention analysis; patients with at least 1 control visit were included in efficacy and safety analysis. Factors predicting good response at the last follow-up visit were analyzed by logistic regression analysis. Drug retention rates were calculated using the Kaplan–Meier method and predictors of drug retention were determined by Cox proportional hazard model. Adverse events, reasons for switching, and discontinuation were also determined. Results Two hundred and forty-seven (210, 85.0% female) patients were included in the study. The median duration of tofacitinib treatment was 10.2 (20.2) [med, (IQR)] months. Two hundred and four (82.6%) patients were included in safety and efficacy analysis; 45.6% of patients were in low-disease activity (LDA) state (DAS28-CRP ≤ 3.2). Predictors of LDA were being biologic-naïve [aOR 2.53 (1.31–4.88); 95% CI] and RF negativity [aOR 2.14 (1.12–4.07); 95% CI]. At 1 year, the overall tofacitinib retention rate was 63.9% with no relevant predicting factor. Response and retention rates of tofacitinib were similar in patients with and without concomitant csDMARDs. Treatment failure was the most common cause of discontinuation. The most common infectious and laboratory adverse events were herpes zoster infection (3.9 per 100 patient-years) and elevation in ALT (x3UNL: 9.7 per 100 patient-years), respectively. Conclusion Tofacitinib is effective as monotherapy or in combination with csDMARDs. It is a well-tolerated treatment option in Turkish RA patients.

Outcomes in rheumatoid arthritis patients treated with abatacept: a UK multi-centre observational study. BMC Rheumatol 2021; 5:3. [PMID: 33536080 PMCID: PMC7857859 DOI: 10.1186/s41927-020-00173-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Accepted: 12/22/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Rheumatoid arthritis (RA) is an inflammatory autoimmune disease that causes chronic synovitis, resulting in progressive joint destruction and functional disability and affects approximately 400,000 people in the UK. This real-world study aimed to describe the characteristics, treatment patterns and clinical outcomes of patients who received abatacept in UK clinical practice. METHODS This was a multi-centre, retrospective, observational study of patients with RA treated with abatacept at four UK centres between 01 January 2013 and 31 December 2017. Data were collected from medical records of each patient from the index date (date of first bDMARD initiation) until the most recent visit, death or end of study (31 December 2017). RESULTS In total, 213 patients were included in the study. Patients received up to eight lines of therapy (LOTs). Treatment with abatacept, or any other bDMARD, was associated with reductions in DAS28-ESR and DAS28-CRP scores at 6 and 12 months. The distribution of EULAR responses (good/moderate/no response) tended to be more favourable for patients when receiving abatacept than when receiving other bDMARDs (22.8%/41.3%/35.9% versus 16.6%/41.4%/42.1% at 6 months, and 27.9%/36.1%/36.1% versus 21.2%/34.5%/44.2% at 12 months). Patients receiving abatacept at LOT1 (n = 68) spent significantly longer on treatment compared with patients receiving other bDMARDs (53.4 vs. 17.4 months; p< 0.01); a similar trend was observed for LOT2. Among patients who discontinued after 6 months, a greater proportion experienced infection requiring antibiotics when receiving other bDMARDs compared to those receiving abatacept. CONCLUSIONS RA patients who received bDMARDs, including abatacept, experienced reduced disease activity. When receiving abatacept as first or second line of therapy, patients persisted with treatment significantly longer than those receiving other bDMARDs.

Abstract
Objective We aimed to develop a scoring model to predict a low disease activity (LDA) in elderly rheumatoid arthritis (RA) patients initially treated with biological disease-modifying antirheumatic drugs (bDMARDs). Methods This retrospective cohort study included 82 elderly RA patients who initially received bDMARDs. The outcome was an LDA after bDMARDs initiation. We developed a predictive formula for an LDA using a multivariate analysis, the accuracy of which was assessed by the area under the curve (AUC) of the receiver operating characteristic curves; the scoring model was developed using the formula. For each factor, approximate odds ratios were scored as an integer, divided into three groups based on the distribution of these scores. In addition, the scoring model accuracy was assessed. Results The mean age was 73.5±6.0 years old, and 86.6% were women. An LDA was achieved in 43 patients (52.4%). The predictive formula for an LDA was prepared using six factors selected for the multivariable analysis: the neutrophil-to-lymphocyte ratio (NLR), anemia, the 28-joint disease activity score with erythrocyte sedimentation rate (DAS28-ESR), serum level of matrix metalloproteinase-3 (MMP-3), diabetes mellitus (DM), and rheumatoid factor (RF). The AUC for the formula was 0.829 (95% confidence interval, 0.729-0.930). The odds ratios of the six factors were scored (DAS28-ESR and serum MMP-3=1 point, NLR, anemia, DM, and RF=2 points) and divided into three groups (≤4, 5-7, and ≥8). The high-score group (≥8) achieved a positive predictive value of 83%. Conclusion The scoring model accurately predicted an LDA in elderly RA patients initially treated with bDMARDs.

Abstract
Abstract
Background
Rheumatoid arthritis (RA) is characterized by presence of localized and generalized osteoporosis. The mechanism of decreased bone mass is complex and multifactorial, a possible mechanism behind increased bone loss in RA is upregulation of sclerostin. The aim of this work was to evaluate serum sclerostin level in RA patients and its relation with bone mineral density (BMD) and disease activity.
Results
Serum sclerostin level in RA patients was significantly higher than the controls (p < 0.001). Osteopenia and osteoporosis were more prevalent in RA patients (22.5% and 7.5% respectively) compared to controls (15% and 2.5% respectively) (p = 0.006). Serum sclerostin level was significantly correlated with tender joint count (p = 0.014), swollen joint count (p = 0.036), erythrocytes sedimentation rate (p = 0.010), C reactive protein serum level (p = 0.025), disease activity score (DAS) 28-ESR (p = 0.018), DAS28-CRP (p = 0.005), and radiological modified Sharp erosion score (p = 0.049). The correlation of serum sclerostin level in RA patients with BMD and with T-score in all sites revealed an inverse relationship with p values insignificant.
Conclusion
Serum sclerostin is a major player in bone metabolism as a negative regulator of bone growth through inhibition of Wnt signaling that is largely influenced by the disease activity. Controlling the disease activity is a major factor for prevention of local as well as generalized osteoporosis and is essential for the reparative local and systemic bone health.

Abstract
To retrospectively evaluate initial tumor necrosis factor inhibitor (TNFi) failure patients for clinical predictors of response to a 2nd TNFi in our 4282 rheumatoid arthritis (RA) patient database.A cross-sectional retrospective manual chart review of the electronic health record (EHR) was performed on 322 "real world" RA patients who were prescribed 2 TNFis. Response to TNFi was determined by the treating provider who had real time Clinical Disease Activity Index (CDAI) scores to inform treatment decisions. Age, gender, body mass index (BMI), insurance provider, duration of disease, cyclic citrullinated peptide antibody (CCP) and rheumatoid factor (RF) positivity, concomitant disease modifying anti-rheumatic drug therapy, length of time between diagnosis and start of 1st and 2nd TNFi, transient efficacy of 1st TNFi (defined as response to TNFi at 3 months but later lost response), and reason for discontinuation of 1st TNFi were analyzed. A multivariable logistic regression model was used to model response to a 2nd TNFi.Response proportions to the 2nd TNFi were greater in females (161/223, 72.2% response female vs 41/75, 54.7% male, P < .01), those who began their 1st TNFi within 3 months of their RA diagnosis, and in RF+ patients (123/170, 72.4% response seropositive vs 66/110, 60.0% seronegative, P < .03). The higher female response rate was independent of age, BMI, and seropositivity.In RA patients who failed an initial TNFi, female patients and patients with RF+ were more likely to have a clinical response to a 2nd TNFi. In the absence of these predictors, stronger consideration for choosing a biologic with an alternative mechanism of action might be given when the 1st TNFi fails.

Abstract
Rheumatoid arthritis (RA), caused by the abnormal recognition of human joint cells by autoimmune antibodies, remains the world’s most prevalent autoimmune disease, with over five million people affected and as much as 4% of the population at risk of RA. To prevent rapid disease development, hormonal and anti-inflammatory therapies require fast and reliable RA diagnosis. However, difficulty in detecting early specific biomarkers for RA means that it is unclear when treatment needs to begin. Here, we combined synthesis of citrullinated peptide epitopes with molecular diagnostics to verify a new specific biomarker for early RA diagnosis and flare prediction. A fibrinogen-derived 21-amino-acid-long citrullinated peptide showed high reactivity toward autoantibodies in RA samples. Additionally, the level of antibodies to this epitope was elevated prior to flares. In contrast, other citrullinated protein variants had lower reactivity and poorer sensitivity to disease activity. In conclusion, fibrinogen-derived epitope E2 subjected to citrullination facilitated a reliable RA diagnosis with a strong correlation to disease activity. This is of a high value for the diagnosis and management of RA patients who respond poorly to treatment.

Predictors of good response to conventional synthetic DMARDs in early seronegative rheumatoid arthritis: data from the ESPOIR cohort. Arthritis Res Ther 2019; 21:243. [PMID: 31730497 PMCID: PMC6858774 DOI: 10.1186/s13075-019-2020-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2019] [Accepted: 10/01/2019] [Indexed: 12/21/2022] Open
Abstract
Background and objective Early seronegative rheumatoid arthritis (RA) is considered a specific entity, especially regarding diagnostic issues and prognosis. Little is known about its potentially different initial clinical presentation and outcome. We aimed to determine predictors of good response to conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) in seronegative RA patients with early inflammatory arthritis. Patients and methods Patients from the ESPOIR cohort with early inflammatory arthritis fulfilling the 2010 ACR/EULAR classification criteria for RA despite negativity for both rheumatoid factor and anti-CCP antibodies. The primary endpoint was a good or moderate EULAR response assessed after 1 year of follow-up, given at least 3 months of treatment with a csDMARD. Secondary objectives were to compare the early therapeutic response to methotrexate (MTX) and leflunomide (LEF) versus other csDMARDs (hydroxychloroquine, sulfasalazine) and to identify factors associated with functional disability (Health Assessment Questionnaire-Disability Index [HAQ-DI] > 0.5 at 1 year) and structural progression (van der Heijde-modified total Sharp score > 1 and > 5 points at 1 year). Logistic regression analysis was used to determine independent predictors of outcomes. Results One hundred seventy-two patients were analyzed. Overall, 98/172 (57%) patients received MTX during the first year of follow-up. A good or moderate EULAR response at 1 year was associated with early use of csDMARDs (i.e., within 3 months after the first joint swelling) on univariate and multivariable analysis (odds ratio = 2.41 [95% confidence interval 1.07–5.42], p = 0.03). Response rates were not affected by other classical prognostic factors (i.e., baseline DAS28). Presence of erosions at baseline was associated with Sharp score progression > 1 point and > 5 points (both p = 0.03) at 1 year. HAQ-DI ≥ 1 at inclusion and active smoking were significantly associated with HAQ-DI > 0.5 at 1 year. Conclusion Our results suggest that delay in initiation of csDMARD more than baseline clinical, biological, or imaging features predominantly affects the outcome in early seronegative RA. These findings confirm that the usual therapeutic concepts in RA (early treatment, tight control, and treat-to-target) should be applied similarly to both seropositive and seronegative disease forms.
