Remote monitoring of rheumatoid arthritis (REMORA): study protocol for a stepped wedge cluster randomized trial and process evaluation of an integrated symptom tracking intervention

BackgroundManagement of rheumatoid arthritis (RA) relies on symptoms reported by patients during infrequent outpatient clinic visits. These reports are often incomplete and inaccurate due to poor recall, leading to suboptimal treatment decisions and outcomes. Asking people to track symptoms in-between visits and integrating the data into clinical pathways may improve this. However, knowledge on how to implement this into practice and its impact on services and outcomes remains scarce in RA. Therefore, we evaluate the comparative effectiveness and cost-effectiveness of integrated symptom tracking in people with RA over and above usual care, while generating insights on factors for successful implementation.MethodsIn this superiority stepped wedge cluster-randomized controlled trial with continuous recruitment short exposure design, 16 rheumatology outpatient departments (clusters) recruit a total of 732 people with active RA. They initially offer clinic visits according to standard of care before switching in pairs to visits with integrated symptom tracking. Clusters switch in randomized order every 3 weeks. Integrated symptom tracking consists of (1) a mobile app for patients to track their symptoms daily and other RA aspects weekly/monthly, and (2) an interactive dashboard visualizing the app data, which healthcare professionals access from their electronic health record system. Clinic visits happen according to usual practice, with tracked symptom data only reviewed during visits. Our primary outcome is a difference in marginal mean disease activity score at 12 ± 3 months between standard of care and integrated symptom tracking, after accounting for baseline values, cluster, and other covariates. Secondary outcomes include patient-reported disease activity, quality of life and quality-adjusted life-years, medication/resource use, consultation and decision-making experience, self-management, and illness perception. We also conduct interviews and observations as part of a parallel process evaluation to gather information on implementation.DiscussionOur trial will generate high-quality evidence of comparative and cost-effectiveness of integrated symptom tracking compared to standard of care in people with RA, with our process evaluation delivering knowledge on successful implementation. This optimizes the chances of integrated symptom tracking being adopted more widely if we find it is (cost-) effective.Trial registrationRegistered 4-Jun-2024 on https://www.isrctn.com/, ISRCTN51539448.Trial open science framework repositoryhttps://osf.io/sj9ha/.

Factors associated with interstitial lung disease in patients with rheumatoid arthritis

Aim: Interstitial lung disease (ILD) is a significant extra-articular manifestation of rheumatoid arthritis (RA). The prevalence and risk factors for ILD in RA exhibit considerable variation. This study aimed to determine the prevalence and factors associated with ILD in Thai patients with RA. Methods: This cross-sectional study enrolled 290 RA patients from the Siriraj Rheumatoid Arthritis Registry between March and December 2022. Patient characteristics, disease activity and functional status were documented. Chest radiography (CXR) was employed for ILD screening, and suspected cases were further evaluated using high-resolution computed tomography (HRCT) and pulmonary function tests. Two radiologists independently analyzed CXR and HRCT images, with any discrepancies resolved by a pulmonologist. Results: Among the 290 patients, the majority were female (89.7%) with mean age (SD) of 58.8 (11.5) years, and the median disease duration was 10 years (range 6–17 years). Patients exhibited low disease activity [mean Disease Activity Score 28-erythrocyte sedimentation rate score (SD) 2.69 (0.90)] and mild functional impairment [median Health Assessment Questionnaire score (range) 0.25 (0–0.63)]. Thirteen patients (4.5%) were diagnosed with ILD via HRCT (RA-ILD), with nonspecific interstitial pneumonia being the predominant ILD pattern (69.2%). Pulmonary function tests showed normal results in most patients, with only 15.5% presenting restrictive ventilatory defects. Age (P = 0.04), breathlessness (P < 0.001), crackles (P < 0.001), and functional impairment (P = 0.02) exhibited significant associations with RA-ILD. Conclusions: ILD is relatively infrequent in Thai patients with RA. However, older age, breathlessness, crackles, and functional impairment should prompt investigations for ILD in RA patients.

Predictors of Drug Retention and Survival Rate of bDMARDs in Rheumatoid Arthritis: A Four-Year Real-Life Tunisian Experience.

This study aims to investigate the efficacy and tolerance of biologic disease-modifying anti-rheumatic drug (bDMARDs) in the current management of rheumatoid arthritis (RA) by identifying the retention time and survival rate of bDMARDs. We conducted a retrospective cohort study including Tunisian patients initiating bDMARD treatment between 2016 and 2018 whose data were collected from the National Health Insurance Fund (NHIF). The NHIF is the national office which organises and centralises patients under bDMARDs from all over the country. Retention and survival rate of bDMARDs at 48 months were analysed using Kaplan-Meier survival curves and compared using the log-rank test. Survival factor analysis was performed using Cox regression. Three hundred seventy-four patients, aged 55.5±12.5years [20-90], (87.2%women), were included. The mean duration of RA was 11.7±6.7 years [2-41]. The mean disease activity score (DAS)28 at initiation of the first bDMARD was 6.01±0.89 [5.37-6.5]. This first bDMARD induced low disease activity (LDA) in 55% of cases. Remission was observed in 28% of patients. The highest LDA and remission rates were observed with Tocilizumab (70.8% and 33.3% of cases, respectively). LDA and remission were achieved within a mean of 45 weeks [26-88] and 72 weeks [31-117] respectively. The 48-month first-line survival rate was 55.9%. Retention time was 41.7 months, 95%CI [39.47-43.91]. Presence of rheumatoid factors, co-prescription of methotrexate, and good initial therapeutic response were factors influencing better survival of bDMARDs (p<0.01). Glucocorticoid use predicted poorer survival (p<10-3). The first bDMARD was interrupted in 39% of cases. Ineffectiveness was the most common cause of treatment cessation (52.7%). This real-life study of the Tunisian population allowed us to establish the factors that can influence the survival and retention rates of bDMARDs.

The Association of Anti-CCP Positivity with Extra-Articular Manifestations in Patients with Rheumatoid Arthritis

Rheumatoid Arthritis (RA) is an autoimmune inflammatory disorder that primarily affects the joints. Objective: To examine association between anti-cyclic citrullinated peptide and extra-articular manifestation of Rheumatoid arthritis. Methods: It was a descriptive cross-sectional study in the Department of Rheumatology outpatient Khyber Teaching Hospital in Peshawar from 13th April 2023 to 13th September 2023. A descriptive cross-sectional study was conducted on 100 patients diagnosed with rheumatoid arthritis according to ACR/EULAR 2010 criteria at the Rheumatology outpatient department of Khyber teaching hospital in Peshawar from 13th April 2023 to 13th September 2023. Sampling technique was non probability consecutive. Statistical analysis was performed using SPSS version 23.0. Results: Our study involved 100 patients diagnosed with rheumatoid arthritis. Majority of the patients were female (90%) with overall mean age was 42.3 ± 10.06 years. The average duration of the disease was 5.9 years, with a mean RA disease activity score of 2.8. Extra-articular manifestations were observed in 84% of the patients, encompassing various symptoms such as anemia, subcutaneous nodules, episcleritis, and interstitial lung disease. Most patients (94%) tested positive for Rheumatoid Arthritis Factor, while 84% tested positive for anti-CCP antibodies. Our analysis revealed significant associations between the presence of extra-articular manifestations and factors such gender distribution, disease activity score and anti-CCP antibody positivity while no significance was noted for factors such as age, Rheumatoid Arthritis Factor and duration of disease. Conclusions: Our study concludes that anti-CCP was positively associated with the presence of extra-articular manifestation of Rheumatoid Arthritis.

P106 Do high rheumatoid factor titres impact response to tumour necrosis factor inhibitors? Comparison of certolizumab pegol and adalimumab in patients with rheumatoid arthritis and high titres of rheumatoid factor: a post hoc analysis of a phase 4 trial.

Abstract Background/Aims In patients with rheumatoid arthritis (RA), high rheumatoid factor (RF) titres are considered a poor prognostic factor and are associated with higher disease activity, risk of radiographic progression and decreased response to TNF inhibitors (TNFis). Recent data suggests that patients with RA and high RF titre may achieve and maintain greater clinical improvement with TNFis without a crystallisable fragment (Fc) compared to TNFis with an Fc. In this analysis of the EXXELERATE trial, we assessed efficacy outcomes of certolizumab pegol (CZP), a PEGylated Fc-free TNFi, versus adalimumab (ADA; Fc-containing TNFi) in patients with RA and high RF titres. Methods The phase 4 EXXELERATE trial (NCT01500278) compared the efficacy and safety of CZP to ADA. Patients were randomised 1:1 to CZP 200 mg every two weeks (Q2W) plus methotrexate (MTX) or ADA 40 mg Q2W plus MTX. At Week 12 (Wk), patients were classified as responders or non-responders; non-responders were switched to the other TNFi with possible follow-up to Wk104. Here, we report drug plasma concentrations, mean disease activity score (DAS)28-CRP score and proportion of patients achieving low disease activity (LDA; threshold: DAS28-CRP ≤2.7) to Wk104. Results are stratified by RF titre quartile (≤Q3: ≤203 IU/mL; &amp;gt;Q3: &amp;gt;203 IU/mL; measured by Roche Tina-quant®) and reported as observed data. Results Baseline data by RF quartile were available for 453 CZP-randomised patients (≤Q3: n = 334; &amp;gt;Q3: n = 119) and 454 ADA-randomised patients (≤Q3: n = 347; &amp;gt;Q3 n = 107). Baseline characteristics were similar between CZP- and ADA-randomised patients across the RF titre quartiles. At Wk12, 66 CZP-treated patients switched to ADA and 59 ADA-treated patients switched to CZP. At Wk104, mean ADA concentrations were 22.9% lower in patients with RF &amp;gt;Q3 (mean [SD] 4.8 [3.0]) vs those with RF ≤Q3 (6.2 [4.0]); in CZP-treated patients, this difference was smaller (13.0%) in patients with RF &amp;gt;Q3 (23.3 [15.4]) vs those with RF ≤Q3 (26.7 [13.1]). For patients in RF ≤Q3, mean DAS28-CRP scores were similar between CZP- and ADA-treated patients through Wks0-104 (mean [SD] DAS28 at Wk104: 2.48 [1.18] CZP vs 2.49 [1.14] ADA). However, for patients in RF &amp;gt;Q3, mean [SD] DAS28-CRP scores were nominally lower in CZP- vs ADA-treated patients (Wk104: 2.50 [1.18] CZP vs 2.93 [1.22] ADA). A similar pattern was observed for the proportion of patients achieving LDA at Wk104 (≤Q3: 64.8% CZP vs 65.1% ADA; &amp;gt;Q3: 65.7% CZP vs 48.3% ADA). Conclusion CZP-treated patients with RA and high titre RF had similar drug concentrations and clinical responses to patients with RA and low titre RF, a pattern not observed in ADA-treated patients. These data, together with previous reports where CZP showed consistent efficacy irrespective of baseline RF titre, suggest CZP may be a suitable therapy for patients with RA and high RF titre.

Two-year treatment persistence with subcutaneous abatacept in rheumatoid arthritis: results from the French cohort of the ASCORE study.

While multiple studies have investigated treatment persistence rates with intravenous abatacept, limited information is available about real-world treatment continuation with the subcutaneous form. The international ASCORE study described the characteristics and treatment persistence of real-world patients with rheumatoid arthritis (RA) receiving subcutaneous abatacept. This article presents the findings of the French cohort. This was an observational study in French RA patients who initiated subcutaneous abatacept between August 2014 and January 2017. The primary endpoint was treatment maintenance at 2 years, analysed according to the number of previous biologic therapies. Of 546 evaluable patients, 281 (51.5%) were biologic-naive, 265 (48.5%) had experienced failure with 1 (n=134; 24.5%) or ≥2 (n=131; 24.0%) biologic therapies. At enrolment, patients who had experienced failure with ≥1 biologic therapy had more erosions and a longer duration of RA compared with biologic-naive patients, but had comparable mean disease activity scores. Overall, 43.0% of patients (95% confidence interval 38.6-47.2) were still taking subcutaneous abatacept at 2 years, which was comparable with that in other countries participating in ASCORE. The abatacept persistence rate was higher in biologic-naive patients (48.8%) than in those with 1 (40.9%) or ≥2 (32.8%) biologic therapy failures. The main reason for discontinuing abatacept was lack of efficacy (46.6%). In current practice in France, the rate of subcutaneous abatacept persistence at 2 years was comparable with that of the intravenous form. Treatment persistence was higher when abatacept was used as first-line versus later-line biologic therapy.

Vatari Guggulu, Hingvashtaka Churna, and Brihat Saindhavadya Taila in the management of rheumatoid arthritis: An open-label, prospective, single-arm multi-center study

Abstract Background: Despite significant advances in the diagnosis and treatment of rheumatoid arthritis (RA), the clinical outcomes remain unsatisfactory in a significant proportion of patients. Ayurveda management for RA (Amavata) has shown promising clinical outcomes in routine clinical practice and as per published research studies. Objective: The study was designed to assess the therapeutic effect and safety of Ayurveda interventions, Vatari Guggulu (VG), Hingvashtaka Churna (HC), and Brihat Saindhavadya Taila (BS) in the management of RA. Materials and Methods: An open-label, prospective, single-arm multicenter study was conducted at Ayurveda Research Institutes in Patna, Bhubaneswar, and Guwahati with a sample size of 180 participants. Patients of any gender aged 20–60 years with clinically diagnosed RA as per the revised American College of Rheumatology criteria and willing to provide written informed consent to participate in the study were included in the study. Ayurveda interventions, VG, HC, and BS, were administered to the study participants for 12 weeks, with a follow-up at four weeks without intervention. The primary outcome measure was a change in the Disease Activity Score-28 (DAS28) from baseline. The other outcome measures included change in the Indian Health Assessment Questionnaire Disability Index score (HAQ-DI), changes in the acute phase reactants (erythrocyte sedimentation rate [ESR] and C-reactive protein [CRP]), and change in the quality of life parameters (assessed through the SF-36 questionnaire). Results: A total of 180 participants were enrolled in the study, and data of 179 participants were considered for the final analysis. A statistically significant difference was observed in the outcome parameters, such as a mean change in the DAS28 score, HAQ-DI score, SF-36 score, and ESR and CRP levels (P &lt; 0.001) after 12 weeks of treatment. The mean DAS28 score changed from 6.50 ± 0.790 at baseline to 4.21 ± 1.286 on week 16 follow-up (P &lt; 0.001). No participant withdrew from the study due to adverse events. The trial interventions were well-tolerated and safe. Conclusion: The study outcomes provide preliminary evidence of the safety and potential benefits of the Ayurveda interventions in the management of RA. Further, randomized controlled studies may be planned to generate robust evidence on the therapeutic potential of these interventions so that they can be recommended for use in routine clinical practice. Trial registration: CTRI/2014/12/005242.

Evaluation of insulin resistance in rheumatoid arthritis in Eastern India

Background: Increase in insulin resistance predisposes to cardiovascular disease. Studies from various parts of world show increase prevalence of IR in rheumatoid arthritis (RA) but there is little data from India. Aims and Objectives: To evaluate the prevalence of IR in RA and after 6 months of treatment with disease-modifying antirheumatic drugs. Materials and Methods: This hospital-based longitudinal observational study was done between July 2018 and June 2019 in the Division of Rheumatology, Department of General Medicine, S.S. Hospital, BHU, in treatment-naive RA patients with age ≥18 years. Exclusion criteria were known diabetes, preexisting dyslipidemias, or any other chronic illness. Detailed history and examination were done. Fasting glucose and fasting insulin were done to calculate the homeostatic model for assessment of IR (HOMA IR). Results: The most common age group in our study was 31–40 years (38%). The mean age of onset of disease was 39.5 years. Female-to-male ratio was 5.25:1. The mean duration of illness was 3 years with baseline mean disease activity score (DAS) 28 score 6.2698 ± 1.07437. Baseline mean cholesterol level, triglyceride, high-density lipoprotein, low-density lipoprotein, and very low-density lipoprotein were 169.40 ± 33.802 mg/dL, 164.42 ± 91.585 mg/dL, 47.66 ± 11.825 mg/dL, 99.88 ± 27.059 mg/dL, and 34.42 ± 19.186 mg/dL, respectively. Baseline fasting blood glucose levels, fasting insulin levels, and HOMA IR were 99.40 ± 20.761 mg/dL, 11.84770 ± 4.351550 m IU/L,and 2.905 ± 1.2272, respectively. After treatment of 6 months, lipid profile, fasting insulin, and HOMA IR improved significantly. However, there was no significant correlation found between IR and disease activity before and after treatment. Conclusion: The patients of RA are at higher risk of IR and dyslipidemia and early diagnosis with the initiation of treatment for RA can reverse the IR in RA patients.

Impact of telemedicine on disease activity assessment: A case-crossover study nested within a cohort of patients with systemic lupus erythematosus.

The utilisation of telemedicine has been rapidly growing among patients with rheumatic diseases, especially following the corona virus disease 2019 pandemic. Ease and convenience appear to dominate the reasons for this growth. However, the effects of this approach in patients with systemic lupus erythematosus (SLE) are yet to be revealed. In this study, we examined the effect of telemedicine on disease activity assessment and damage scores in patients with SLE. This case-crossover study was nested within a national prospective cohort of patients with SLE in Saudi Arabia. Patients with SLE were included if they fulfilled the Systemic Lupus International Collaborating Clinics classification criteria between March 2020 and March 2021 and were assessed at three time points with 3 months between assessments, according to the standardised protocol of this cohort. Telemedicine was conducted for the first evaluation, while in-person assessments were used at the second and third visits. The primary outcome was the difference in the SLE disease activity index 2000 (SLEDAI-2K) score. The primary analysis was conducted using the repeated measure model and adjusted for potential confounders, including demographics, medications, and changes in steroid doses. Several sensitivity analyses were conducted to mitigate selection and time-varying confounders. A total of 92 participants were included in this study. Most patients were females (88%), with a mean (±standard deviation [SD]) age of 36 (±13) years. The mean (±SD) disease activity scores at baseline were as follows: SLEDAI-2K, 5 (±5); SLE responder index, 3.8 (±3.5); Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index, 1 (±1). The mean difference in SLEDAI-2K score was -1.641 (95% confidence interval -2.773 to -0.510, p = 0.005*) between telemedicine and follow-up visits. The results were consistent in all sensitivity analyses. We found that telemedicine assessment was associated with a much higher disease activity score than subsequent assessments, which may suggest an overestimation of disease activity and later assessment accuracy. Cautious adoption has been suggested for SLE patients with active disease.

Body mass index does not affect response of rituximab in patients with rheumatoid arthritis: results from the TURKBİO registry.

Adipose tissue produces several inflammatory mediators. Thus, obesity affects the disease course and the responses to the antirheumatic agents in inflammatory diseases. The aim of the study was to determine whether the body mass index (BMI) is involved in the response to rituximab in rheumatoid arthritis (RA). This multicenter retrospective study included 206 RA patients who received rituximab from the Turkish Biologic (TURKBIO) registry between 2011 and the end of May 2017. Demographic and clinical data including age, sex, disease type, disease duration, and previous or current treatment with disease-modifying antirheumatic drugs (DMARDs) and biological drug durations are stored in the database. Patients with a BMI ≥30 kg/m2 were classified as obese, and patients with a BMI <30 kg/m2 were classified as nonobese. Kaplan-Meier survival analysis was performed to estimate the drug survival. The subgroups were compared using the log-rank test. The mean BMI of 206 patients included in the study was 27.05 (17.2-43.4) kg/m2. There were 59 (28.6%) patients in the obese group and 147 (71.4%) patients in the nonobese group. The mean age, female percentage, and baseline disease activity score 28 (DAS28) were higher in the obese group than in the nonobese group. However, the ΔDAS28 at both 6 and 12 months were not significantly different between the groups (p = 0.785 and p = 0.512, respectively). Patient pain Visual Analogue Scale (VAS), patient fatigue VAS, and patient global VAS scores were also significantly higher at baseline in the obese group (p = 0.003, p = 0.006, and p = 0.006, respectively). However, no significant difference was found in terms of changes in patient pain VAS, patient fatigue VAS, patient global VAS and physician global VAS scores at 6 and 12 months compared to those at baseline. Rituximab treatment was ongoing for 71.2% of the obese and 63.3% of the nonobese patients (p = 0.279). The median drug survival duration was 77 months in the obese group and 62 months in the nonobese group (p = 0.053). The estimated drug survival rates for rituximab were not statistically significantly different in the obese and nonobese groups. Rituximab-related side effects were also similar between the groups. In obese and nonobese patients with RA, rituximab treatment exhibits similar side effects and similar long-term efficacy. These results suggest that obesity does not alter drug survival for rituximab and response rates, in RA and rituximab may be a favorable treatment agent in patients with RA and obesity.

Monotreatment With Conventional Antirheumatic Drugs or Glucocorticoids in Rheumatoid Arthritis

This is the first network meta-analysis to assess outcomes associated with multiple conventional synthetic disease-modifying antirheumatic drugs and glucocorticoid. To analyze clinical outcomes after treatment with conventional synthetic disease-modifying antirheumatic drugs and glucocorticoid among patients with rheumatoid arthritis. With no time restraint, English language articles were searched in MEDLINE, Embase, Cochrane Central, ClinicalTrials.gov, and reference lists of relevant meta-analyses until September 15, 2022. Four reviewers in pairs of 2 independently included controlled studies randomizing patients with rheumatoid arthritis to mono-conventional synthetic disease-modifying antirheumatic drugs, glucocorticoid, placebo, or nonactive treatment that recorded at least 1 outcome of tender joint count, swollen joint count, erythrocyte sedimentation rate, and C-reactive protein level. Of 1098 assessed articles, 130 articles (132 interventions) were included. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline, and data quality was assessed by the Cochrane risk of bias tool RoB 2. Data were extracted by a single author and checked independently by 2 authors. Data were analyzed using a random effect model, and data analysis was conducted from June 2021 to February 2023. A protocol with hypothesis and study plan was registered before data recording. The most complete of recorded outcomes (tender joint count) was used as primary outcome, with imputations based on other outcomes to obtain a full analysis of all studies. Absolute change adjusted for baseline disease activity was assessed. A total of 29 interventions in 275 treatment groups among 132 randomized clinical trials (mean [range], 71.0% [27.0% to 100%] females in studies; mean [range] of ages in studies, 53 [36 to 70] years) were identified, which included 13 260 patients with rheumatoid arthritis. The mean (range) duration of RA was 79 (2 to 243) months, and the mean (range) disease activity score was 6.3 (4.0 to 8.8). Compared with placebo, oral methotrexate was associated with a reduced tender joint count by 5.18 joints (95% credible interval [CrI], 4.07 to 6.28 joints). Compared with methotrexate, glucocorticoid (-2.54 joints; 95% CrI, -5.16 to 0.08 joints) and remaining drugs except cyclophosphamide (6.08 joints; 95% CrI, 0.44 to 11.66 joints) were associated with similar or lower tender joint counts. This study's results support the present role of methotrexate as the primary reference conventional synthetic disease-modifying antirheumatic drug.

Should complete B cell depletion be maintained in patients treated long-term with rituximab for rheumatoid arthritis?

To determine whether persistent complete B cell (BC) depletion was associated with a better clinical response in rheumatoid arthritis (RA) patients long-term treated with rituximab (RTX). We conducted a retrospective study including RA patients admitted for a new infusion between 2019 and 2021. The primary endpoint was the comparison of the mean disease activity score based on 28 joints (DAS28)-CRP at each of the four last infusion visits between patients with persistent complete BC depletion (mean CD19 counts <18/µl at each of the last four visits) or without persistent complete BC depletion (mean CD19 counts of the last four visits ≥18/µl). Secondary endpoints included DAS28, pain/fatigue visual analogue scale, CRP, gammaglobulins and the frequency of self-reported RA flares. Of the 126 patients in maintenance therapy with RTX [exposure period: 76 (5) months, 14 (7) infusions received], 43 (34%) had persistent complete BC depletion at each of the four last infusions. The mean DAS28-CRP calculated at each of the four last infusion visits did not significantly differ according to persistence or not of complete BC depletion. This result remained unchanged after adjusting for antibody status, number of previous therapies, number of RTX infusion and cumulative RTX dose. All secondary outcomes were also not significantly different between the two groups. Maintaining complete BC depletion does not appear to be a therapeutic target to achieve in RA patients in long-term maintenance therapy with RTX. There is a limited benefit of monitoring CD19 in RA patients long-term treated with RTX and having achieved low disease activity/remission.

Relationship between Mean Platelet Volume and Disease Activity Score in Patients Presenting with Rheumatoid Arthritis

Background: Rheumatoid arthritis (RA) is a chronic inflammatory disorder characterized by the presence of joint inflammation, joint pain, and the progressive deterioration of synovial joints. As a consequence, individuals have physical impairment and an increased susceptibility to premature death. Objective: In order to determine the correlation between mean platelet volume and disease activity score in individuals diagnosed with rheumatoid arthritis. Study Design: Cross sectional study design. Settings: Department of Rheumatology Sheikh Zayed Hospital, Lahore Pakistan. Duration: 6th October 2021 to 5th April 2022. Methods: In this research, 140 participants of varying genders, aged between 20 and 70 years, were included, all of whom were diagnosed with rheumatoid arthritis. To evaluate disease activity, the researchers utilized the Disease Activity Score (DAS-28), and the mean platelet volume (MPV) was measured through routine complete blood examination. Results: The patient cohort spanned from 20 to 70 years old, with an average age of 45.85 ± 12.24 years. Among them, 33 (23.6%) were male, and 107 (76.4%) were female, resulting in a female-to-male ratio of 3.2:1. The duration of rheumatoid arthritis varied from 6 to 72 months, averaging 38.36 ± 16.93 months. Patients' DAS-28 scores ranged from 2.6 to 10.0, with a mean of 5.52 ± 2.10, while their mean platelet volume (MPV) ranged from 6.5 fl to 13.5 fl, with an average of 9.99 ± 1.98 fl. Conclusion: There was significantly strong negative correlation between disease activity score and mean platelet volume in patients suffering from rheumatoid arthritis across all age and gender groups.

Periodontal health status, Porphyromonas gingivalis and anti-cyclic citrullinated peptide antibodies among rheumatoid arthritis patients

Porphyromonas gingivalis (P. gingivalis) is the primary periodontal pathogen involved in protein citrullination, which triggers the production of anti-cyclic citrullinated peptide (anti-CCP) antibodies, exacerbating rheumatoid arthritis (RA). This study aims to evaluate the amount of P. gingivalis and its association with anti-CCP antibodies in RA patients with periodontitis. This cross-sectional study involves 100 RA patients with a mean age of 52.36 (SD 13.90) years. Smokers and patients with other uncontrolled systemic diseases were excluded. Disease Activity Score-28 (DAS-28) was used to determine RA disease severity. Periodontal parameters were examined to determine periodontal status. Subsequently, plaque samples were collected from the subgingival periodontal pocket for assessment of P. gingivalis bacterial load using the loop-mediated isothermal amplification method. Blood samples (5 ml) were obtained from all participants to analyse anti-CCP antibody levels. Data was analysed by using SPSS version 24.0. Most participants were female (85.0%) and had low RA disease severity (62%). The mean RA disease duration was 7.77 (SD 6.3) years, with a mean DAS-28 of 3.17 (SD 1.0). Forty-seven per cent of participants had periodontitis, but all periodontal parameters were not associated with RA disease activity (P = 0.38). P. gingivalis bacterial load ranged from 10 to 109 copies/μl. Fifty-five per cent of the collected samples showed positive anti-CCP antibody levels, but no significant association was observed with the P. gingivalis bacterial load (P = 0.58). Considering the study's limitations, although periodontitis is prevalent among RA patients, there is a lack of association between P. gingivalis bacterial load and anti-CCP antibody levels, which should be investigated further.

Impacts of the 2019 pandemic of severe acute respiratory syndrome–coronavirus 2 on the quality of life of patients with inflammatory rheumatic diseases

Purpose: The aim of this study was to assess the impact of the SARS-CoV-2 pandemic and protective measures on the QoL of patients with inflammatory rheumatic diseases (IRDs) who received treatment at the Department of Rheumatology at the University Medical Centre Maribor (UCM-MB).&#x0D; Methods: A questionnaire was sent to IRD patients who visited a rheumatology outpatient clinic or were contacted by phone or virtually at least once between February 1, 2020 and May 30, 2021. The questionnaires were included if returned to UCM-MB by January 1, 2022 and were completed correctly and in full.&#x0D; Results: Of the 125 patients who met the inclusion criteria, 57 (45.6%) had no cancelled rheumatology appointments, 52 (41.6%) had one, 15 (12.0%) had two, and one patient (0.8%) had three. The most preferred mode of communication was in-person meetings with a rheumatologist (89%) and the least was a video call (1%). Only 2% of patients had problems obtaining medication during the pandemic, but none reported consequences with disease status. More than half (58%) of patients agreed with the restrictions during the pandemic and 5% stated the restrictions should be terminated. Most (70%) patients were vaccinated against SARS-CoV-2 and 21% reported SARS-CoV-2 infection. The mean disease activity score (DAS-28) was 3.100 ± 1.292 (rheumatoid arthritis, 3.252 ± 1.209; psoriatic arthritis, 2.927 ± 1.376; p = 0.274; t = 1.101).&#x0D; Conclusion: The pandemic and associated protective measures had deleterious effects on the QoL of IRD patients.

Aortic-brachial stiffness mismatch as potential marker of subclinical arterial damage in patients with rheumatoid arthritis

Aortic-brachial stiffness mismatch is a potential new marker of a subclinical vascular damage that has never been studied in patients with rheumatic diseases. The aim of the study was to assess the frequency of arterial stiffness mismatch in rheumatoid arthritis (RA) and to evaluate its clinical associations. Materials and Methods. The study group included 85 patients with RA (males 22.4 %, aged 59.7 ± 14.3 years, hypertension in 65 %, mean disease activity score (DAS-28 (C-reactive protein) 3.7 ± 1.1), and the control group included 40 subjects matched by gender, age and risk factors. The study methods included measurements of clinical and ambulatory brachial and aortic blood pressure (BP) (BPLab-Vasotens), arterial stiffness parameters parameters (applanation tonometry, SphygmoCorAtCor), cardio-ankle vascular index (VaSera) and cardio-vascular risk assessments using the SCORE, American College of Cardiology/American Heart Association (ACC/AHA) 2013 pooled cohort equations and QRisk2 scoring systems. The arterial stiffness gradient was calculated as a ratio between carotid-femoral (cf) and carotid-radial (cr) pulse wave velocity, and its elevation of ≥ 1 was considered as arterial stiffness mismatch. A p-value of 0.05 was considered significant. Results and Discussion. The mean stiffness gradient in RA patients without and with hypertension was 1.1 ± 0.1 and 1.4 ± 0.4, respectively (р 0.001); in controls, 0.99 ± 0.2 and 1.3 ± 0.3, respectively (р 0.001). The frequency of stiffness mismatch in the RA group was significantly higher compared to the controls in the whole study population (88.2 % vs 65 % (р = 0.002)) and in both normotensive and hypertensive subgroups (76.7 % vs 43.8 % (p = 0.03), and 94.5 % vs 79.2 % (p = 0.04), respectively). The same trend was observed in the subgroups with normal carotid-femoral pulse wave velocity: arterial stiffness mismatch was present in 82.1 % of RA patients vs. 51.9 % control subjects (p = 0.004). The stiffness gradient was associated with age (r = 0.63), hypertension duration (r = 0.56), cardio-vascular risk by the ACC/AHA 2013 (r = 0.69) and Qrisk2 (r = 0.7) scoring systems, nocturnal aortic systolic BP (r = 0.53), cardio-ankle vascular index (r = 0.60) and diurnal index of brachial systolic BP (r = -0.4). Significant differences in stiffness gradient values were observed in the subgroups based on elevation of aortic systolic BP and pulse wave velocity above individual reference values, aortic pulse pressure 50 mmHg, cardio-ankle vascular index 9, presence of high cardio-vascular risk, masked and nocturnal hypertension, and non-dipping. Conclusion. Patients with RA are characterized by higher frequency of arterial stiffness mismatch compared to controls, irrespective of the history of hypertension or the values of carotid-femoral pulse wave velocity. Arterial stiffness mismatch is associated with unfavorable 24-h BP profile, higher frequency of nocturnal hypertension and cardio-vascular risk.

Screening of silent myocardial ischaemia using a stress test in rheumatoid arthritis patients: Association with traditional risk factors and disease activity.

We aimed to screen the presence of silent myocardial ischaemia, in established rheumatoid arthritis (RA) patients, using a stress test then to evaluate its association with the disease activity and the cardiovascular (CV) risk factors and Heartscore. It is a transversal study in a rheumatologic centre in Tunisia. One hundred three RA patients, asymptomatic for CV diseases, were submitted to a stress test. Demographic data, CV risk factors and disease characteristics were assessed and risk factors of silent myocardial ischaemia in RA patients were identified. There were 103 patients (sex-ratio=0.3) with a mean age of 53±10years. The evaluation of the disease activity showed that the mean Disease Activity Score in 28 joints C-reactive protein, Clinical Disease Activity Index and Simplified Disease Activity Index were 3.9±1.38, 17.17±11.4 and 33.39±26, respectively. The ischaemic ratio (CT/HDL) revealed that 42% of patients had a moderate to high myocardial ischaemic risk. HeartSCORE was high in 35% of cases. A silent myocardial ischaemia in the stress test was found in 11 patients (10.6%) and was associated with male sex (p=0.03), advanced age (p=0.04), erosive character (p=0.05), the advanced age of the RA diagnosis (p=0.01) and the ischaemic ratio (p=0.05). No relationship was found with the majority of traditional CV risk factors nor with disease activity variables. Our results corroborated the hypothesis that the stress test could reveal subclinical CV dysfunction and supported the utility of the Heartscore as a screening tool.
