Background: Rheumatoid arthritis is an ailment that has an effect on the lungs in cases of pleural inflammation; it affects the lower as well as upper lung airways. Other effects of the disease can be seen in interstitial lung problems (parenchyma) and pulmonary vasculature. Aim: Evaluating the occurrence of pulmonary manifestations in RA patients was the objective of this study. Methods: An observatory method that was cross-section in nature was employed in this study which was held in the Rheumatology and Medicine department, Jinnah Medical and Dental College Karachi Pakistan for the one-year duration from June 2020 to June 2021. Eighty subjects were included in this study, and all of them underwent a general examination, their medical history was taken into account. Several lab tests were performed on the patients, ESR, BUN, CRP, HRCT, ALT, radiological investigations, and chest X-rays were included. Results: In this study42 percent of patients presented with pulmonary manifestations. About 45.70 percent of the patients presented with abnormalities in the spirometry test, 42.85 percent showed HRCT abnormalities. The HRCT scores vary with age, TJC (Tender Joint Count), ESR, and SJC.FEV, 1 HRCT, and FCV showed a negative correlation among each other. However other variables did not show any statistically significant correlation. Conclusion: RA showed the prevalence of pulmonary affection, and this can be observed in pulmonary and radiological functions. There was an associationof age, pulmonary functions, and ESR.

ObjectivesTo determine whether MRI and conventional (clinical and laboratory) measures of inflammation can predict 3-year radiographic changes measured by the van der Heijde Sharp score in patients with early rheumatoid arthritis (RA).Methods55 patients with RA with disease duration <1 year participated in this 3-year follow-up study. Patients were evaluated at baseline, 3, 6, 12 and 36 months by swollen and tender joint count, disease activity score based on 28-joint count, erythrocyte sedimentation rate (ESR), C reactive protein, MRI measures of synovitis, bone marrow oedema and tenosynovitis of the dominant wrist, as well as conventional x-rays of the hands and wrists.ResultsAll measures of inflammation decreased during the follow-up period. ESR, MRI synovitis and MRI bone marrow oedema were independent predictors of 3-year radiographic progression adjusted for age, sex and anti-citrullinated protein antibodies. The 1-year cumulative measures of MRI synovitis and bone marrow oedema provided an improved explanation of variation (adjusted R2) in radiographic change compared with the baseline MRI values (adjusted R2=0.32 and 0.20 vs 0.11 and 0.04, respectively).ConclusionsBoth baseline and 1-year cumulative measures of MRI synovitis and bone marrow oedema independently predicted 3-year radiographic progression. These results confirm that MRI synovitis and MRI bone marrow oedema precede radiographic progression in patients with early RA.

Background: Rheumatoid Arthritis (RA) is the most common type of chronic inflammatory arthritis with unknown etiology marked by a symmetric, peripheral polyarthritis. Calprotectin also can be used as a biomarker of disease activity in inflammatory arthritis and other autoimmune diseases. Objective: In this study, we evaluated the association between serum calprotectin level and severity of RA activity. Methods: A cross-sectional study was conducted on 44 RA patients with disease flare-up. Serum samples were obtained from all patients to measure calprotectin, ESR, CRP prior to starting the treatment and after treatment period in the remission phase. Based on Disease Activity Score 28 (DAS28), disease activity was calculated. Results: Of 44 RA patients, 9(20.5%) were male and 35(79.5%) were female. The mean age of our cases was 53±1.6 years. Seventeen (38.6%) patients had moderate DAS28 and 27(61.4%) had high DAS28. The average level of calprotectin in the flare-up phase was 347.12±203.60 ng/ml and 188.04±23.58 ng/ml in the remission phase. We did not find any significant association between calprotectin and tender joint count (TJC; P=0.22), swollen joint count (SJC; P=0.87), and general health (GH; P=0.59), whereas significant associations were found between the calprotectin level and ESR (p=0.001) and DAS28 (p=0.02). The average calprotectin level in moderate DAS28 (275.21±217.96 ng/ml) was significantly lower than that in high DAS28 (392.4±183.88 ng/ml) (p=0.05). Conclusion: We showed that the serum level of calprotectin can be a useful and reliable biomarker in RA activity and its severity. It also can predict treatment response.

ObjectivesTo define fatigue trajectories in patients with rheumatoid arthritis (RA) who initiate biological DMARD (bDMARD) treatment, and explore baseline predictors for a trajectory of continued fatigue.MethodsOne-hundred and eighty-four patients with RA initiating bDMARDs were assessed at 0, 1, 2, 3, 6 and 12 months. Swollen and tender joint counts, patient reported outcomes (PROMs), blood samples and ultrasound examinations were collected at each time point. Fatigue was assessed by the fatigue Numeric Rating Scale (0–10) from the Rheumatoid Arthritis Impact of Disease (RAID) questionnaire. Clinically significant fatigue was predefined as fatigue ≥4. Three trajectories of interest were defined according to level of RAID fatigue: no fatigue (≤3 at 5/6 visits), improved fatigue (≥4 at start, but ≤3 at follow-up) and continued fatigue (≥4 at 5/6 visits). Baseline variables were compared between groups by bivariate analyses, and logistic regression models were used to explore baseline predictors of continued vs improved fatigue.ResultsThe majority of patients starting bDMARD therapy followed one of three fatigue trajectories, (no fatigue; n=61, improved; n=33 and continued fatigue; n=53). Patients with continued fatigue were more likely to be anti–citrullinated protein antibody and/or rheumatoid factor positive and had higher baseline PROMs compared to the other groups, while there were no differences between the groups for variables of inflammation including. Patient global, tender joint count and anxiety were predictors for the continued fatigue trajectory.DiscussionA trajectory of continued fatigue was determined by PROMs and not by inflammatory RA disease activity.

Background:The therapeutic aim for rheumatoid arthritis (RA) is to control disease activity and prevent radiographic progression. Various clinical scores are utilized to describe disease activity in RA patients. The DAS28 score can define states of low disease activity (LDA) and remission. Despite achieving LDA or remission, radiographic progression may nevertheless occur. However, the rates and frequency of this occurrence have not been analyzed in detail.Objectives:To describe the frequency and rate of radiographic progression in patients with persistent LDA or remission.Methods:Analysis of RA patients from the SCQM cohort. Persistent LDA or remission were defined as DAS 28 ≤3.2 or <2.6 respectively, at two subsequent follow up time points in the database. We included patients with at least two sets of radiographs within these intervals of LDA and/or remission. Radiographic progression was measured with the Ratingen-score (range 0-190), which describes joint erosions numerically. Repair was defined as an improvement in the Ratingen score >5 points/year and progression as >2 or >5 points change in the Ratingen score within one year.Results:Among 10’141 RA patients, 4’342 episodes of remission occurred in 3’927 patients with 1’776 sets of X rays available within these episodes. Similarly, 8’136 episodes of LDA in 6’765 patients and 2’358 sets of X rays were present within these intervals. For patients in LDA or remission, rates of repair were 5.5% and 4.8%, respectively, while for radiographic progression >5 points in the Ratingen score/year were 10.3% in both groups and for >2 points change of Ratingen score/year were 27.7 and 25.4%, respectively).No differences for demographic factors or measures of disease activity, rheumatoid factor or ACPA were found comparing patients with radiographic progression or non-progression despite LDA or remission at the beginning of the episode of LDA and/or remission.Interestingly, 42.9% of patients in LDA with progression of >5 points in the Ratingen score/year were current smokers vs 29.4% among the non-progressors (X2 = 6.55, p = 0.01). This significant difference vanished when the cut-off for radiographic progression was set at >2 points yearly change in Ratingen score or in patients in remission.Conclusion:Radiographic progression despite LDA or remission are more frequent than expected. No differences in radiographic progression were found comparing LDA and remission suggesting that the goal of LDA is appropriate. Smoking seems to be an independent risk factor for radiographic progression despite LDA. Why the effect of smoking could was not demonstrated in patients in remission, remains unclear.Disclosure of Interests:Lena Brandt: None declared, Hendrik Schulze-Koops: None declared, Thomas Hügle Consultant of: GSK, Abbvie, Pfizer, Jansen, Novartis, Eli Lilly., Michael J.

Tender Joint Counts

Objective.Patient self-report outcomes and physician-performed joint counts are important measures of disease activity and treatment response. This metaanalysis examines the degree of concordance in joint counts between trained assessors and patients with rheumatoid arthritis (RA).Methods.Studies eligible for inclusion met the following criteria: English language; compared patient with trained assessor joint counts; peer-reviewed; and RA diagnosis determined by board-certified or board-eligible specialist or met 1987 American College of Rheumatology criteria. We searched PubMed and Embase to identify articles between 1966 and January 1, 2008. We compared measures of correlation between patients and assessors for either tender/painful or swollen joint counts. We used metaanalysis methods to calculate summary correlation estimates.Results.We retrieved 462 articles and 18 were included. Self-report joint counts were obtained by a text and/or mannequin (picture) format. The summary estimates for the Pearson correlation coefficients for tender joint counts were 0.61 (0.47 lower, 0.75 upper) and for swollen joint counts 0.44 (0.15, 0.73). Summary results for the Spearman correlation coefficients were 0.60 (0.30, 0.90) for tender joint counts and 0.54 (0.35, 0.73) for swollen joint counts.Conclusion.A self-report tender joint count has moderate to marked correlation with those performed by a trained assessor. In contrast, swollen joint counts demonstrate lower levels of correlation. Future research should explore whether integrating self-report tender joint counts into routine care can improve efficiency and quality of care, while directly involving patients in assessment of RA disease activity.

BACKGROUND: Fibromyalgia syndrome (FM) is a systemic disease of unknown etiology, which can cause widespread musculoskeletal pain. In patients with rheumatoid arthritis (RA), FM can cause an additional symptom burden, which can affect some variables on the RA disease activity score 28 (DAS28), a tool that evaluates 28 joints in RA patients. OBJECTIVE: Compare the results of four different versions of the DAS28 and the parameters used to determine disease activity scores in RA patients with and without FM, and determine whether there are treatment differences between RA patients with and without FM. DESIGN: Retrospective, cross-sectional. SETTING: Tertiary hospital. PATIENTS AND METHODS: We identified patients diagnosed with RA between 1 September 2016 and 1 February 2020 and identified patients with and without FM. MAIN OUTCOME MEASURES: Differences between variables in the DAS28 calculations (tender joint count [TJC], patient global assessment [PGA], and others), between patients with and without FM, and differences between patients with and without FM who were using or not using biological agents. SAMPLE SIZE: 381, including 322 females (84.5%). RESULTS: The frequency of FM in RA patients was 25.7% (89 females, 24.6%). In RA patients with FM, the TJC and PGA median values were significantly higher than in patients without FM ( P <.05). The use of corticosteroids and biological therapy in patients with FM was more frequent than in patients without FM ( P <.05). Compared to patients without FM, patients with FM switched treatment more often because of non-response to treatment ( P =.01) Median values of the DAS28 scores (calculated by four different versions of the instrument) in RA patients with FM were higher than in patients without FM ( P <.05). CONCLUSION: The presence of FM in RA patients may affect the subjective variables in different versions of DAS28 scores, causing the disease activity to score higher on the instrument, erroneously indicating worse disease than is actually present. LIMITATIONS: A single center, retrospective study. CONFLICTS OF INTEREST: None.

Abstract Background Monocytes as precursors of osteoclasts in rheumatoid arthritis (RA) are well demonstrated, while monocyte subsets in osteoclast formation are still controversial. Tyro3 tyrosine kinase (Tyro3TK) is a member of the receptor tyrosine kinase family involved in immune homeostasis, the role of which in osteoclast differentiation was reported recently. This study aimed to compare the osteoclastic capacity of CD14+CD16+ and CD14+CD16− monocytes in RA and determine the potential involvement of Tyro3TK in their osteoclastogenesis. Methods Osteoclasts were induced from CD14+CD16+ and CD14+CD16− monocyte subsets isolated from healthy control (HC) and RA patients in vitro and evaluated by tartrate-resistant acid phosphatase (TRAP) staining. Then, the expression of Tyro3TK on CD14+CD16+ and CD14+CD16− monocyte subsets in the peripheral blood of RA, osteoarthritis (OA) patients, and HC were evaluated by flow cytometry and qPCR, and their correlation with RA patient clinical and immunological features was analyzed. The role of Tyro3TK in CD14+CD16− monocyte-mediated osteoclastogenesis was further investigated by osteoclast differentiation assay with Tyro3TK blockade. Results The results revealed that CD14+CD16− monocytes were the primary source of osteoclasts. Compared with HC and OA patients, the expression of Tyro3TK on CD14+CD16− monocytes in RA patients was significantly upregulated and positively correlated with the disease manifestations, such as IgM level, tender joint count, and the disease activity score. Moreover, anti-Tyro3TK antibody could inhibit Gas6-mediated osteoclast differentiation from CD14+CD16− monocytes in a dose-dependent manner. Conclusions These findings indicate that elevated Tyro3TK on CD14+CD16− monocytes serves as a critical signal for osteoclast differentiation in RA.

Objective.We compared variations among Canadian provinces in rheumatoid arthritis (RA) initiating anti-tumor necrosis factor (TNF) therapy.Methods.Data were obtained from the Optimization of Humira trial (OH) and from the Ontario Biologics Research Initiative (OBRI). Baseline characteristics were compared between regions: Ontario (ON), Quebec (QC), and other provinces (OTH). We compared Ontario OH to OBRI patients who were initiating anti-TNF therapy.Results.In 300 OH patients, mean age was 54.8 years (13.3). There were 151 (50.3%) ON patients, 57 from QC (19%), and 92 from OTH (30.7%). Regional differences were seen in the number of disease-modifying antirheumatic drugs (DMARD) ever taken (ON: 3.8 ± 1.4, QC: 3.1 ± 1.1, OTH: 3.3 ± 1.4; p < 0.001); swollen joint count (SJC; ON: 10.9 ± 5.9, QC: 9.0 ± 4.4, OTH: 11.3 ± 5.6; p = 0.033); tender joint count (TJC; ON: 12.2 ± 7.5, QC: 10.3 ± 5.7, OTH: 14.4 ± 7.6; p = 0.003); 28-joint Disease Activity Score (DAS28; ON: 5.8 ± 1.2, QC: 5.6 ± 1.0, OTH: 6.0 ± 1.1; p = 0.076); and Health Assessment Questionnaire (ON: 1.4 ± 0.7, QC: 1.7 ± 0.7, OTH: 1.5 ± 0.7; p = 0.060). DMARD-ever use differed: methotrexate (ON: 94.7%, QC: 93%, OTH: 84.8%; p = 0.025); leflunomide (ON: 74.8%, QC: 21.1%, OTH: 51.1%; p < 0.001); sulfasalazine (ON: 51%, QC: 38.6%, OTH: 25%; p < 0.001); myochrysine (ON: 9.3%, QC: 0%, OTH: 15.2%; p = 0.008); and hydroxychloroquine (ON: 67.5%, QC: 86%, OTH: 66.3%; p = 0.018). In comparison to ON OH patients, 95 OBRI patients initiating first anti-TNF had lower SJC (p = 0.017), TJC (p = 0.008), and DAS28 (p = 0.05).Conclusion.In Quebec, where access to anti-TNF is less restrictive, patients had lower SJC and TJC. ON used more DMARD, especially leflunomide, as mandated by the provincial government. Both provincial funding criteria and prescribing habits may contribute to differences. Canadian rheumatologists may vary in treatment decisions, but patients generally have similar DAS28 when initiating anti-TNF therapy.

ObjectiveAntifibrillar collagen type II (anti-CII) antibody-positive patients with rheumatoid arthritis (RA) have early but not late signs of increased inflammation and joint erosions. We wanted to replicate this in a large RA cohort, and to relate to human leukocyte antigen (HLA)-DRB1* alleles.MethodsAnti-CII and anti-cyclic citrullinated peptide (CCP)2 were measured at baseline in 773 patients with RA from the Swedish Epidemiological Investigation in Rheumatoid Arthritis (EIRA) study with clinical follow-up data from the Swedish Rheumatology Quality Register (SRQ) registry, and 1476 with HLA-DRB1* information. Comparisons were done concerning C reactive protein (CRP), erythrocyte sedimentation rate (ESR), tender joint count (TJC), swollen joint count (SJC), Disease Activity Score encompassing 28 joints based on ESR (DAS28), DAS28CRP, pain-Visual Analogue Scale (VAS), global-VAS and Health Assessment Questionnaire Score (HAQ) at eight occasions during 5 years, and association with HLA-DRB1* alleles.ResultsAnti-CII associated with elevated CRP, ESR, SJC, DAS28 and DAS28CRP at diagnosis and up to 6 months, whereas anti-CCP2 associated with SJC and DAS28 from 6 months to 5 years, but not earlier. The anti-CII-associated phenotype was strong, and predominated in anti-CII/anti-CCP2 double-positive patients. Anti-CII was associated with improvements in CRP, ESR, SJC, TJC and DAS28, whereas anti-CCP2 was associated with deteriorations in SJC and DAS28 over time. Anti-CII-positive patients achieved European League Against Rheumatism good or moderate response more often than negative patients. Anti-CII was positively associated with HLA-DRB1*01 and HLA-DRB1*03, with significant interaction, and double-positive individuals had >14 times higher mean anti-CII levels than HLA double negatives. Whereas smoking was associated with elevated anti-CCP2 levels, smokers had lower anti-CII levels.ConclusionsAnti-CII seropositive RA represents a distinct phenotype, in many respects representing the converse to the clinical, genetic and smoking associations described for anticitrullinated protein peptide autoantibodies. Although not diagnostically useful, early anti-CII determinations predict favourable inflammatory outcome in RA.
