Rheumatoid Arthritis: Clinical-Laboratory and Ultrasound Parallels

Purpose. To establish the relationship of serum adiponectin and leptin with clinical data, serological parameters, disease activity, results of ultrasound examination of the musculoskeletal system and X-ray damage of joints in rheumatoid arthritis patients.Materials and methods. The article presents a comparative characteristic of adipokine levels among 64 women diagnosed with rheumatoid arthritis (group I) and 30 healthy women (group II). The dependence of adipokine levels on clinical, laboratory, ultrasound and radiological changes was revealed in patients with rheumatoid arthritis.Results. The concentration adiponectin level was significantly higher in rheumatoid arthritis patients compared to the control group (p <0.0001) and had significant correlations with radiological changes in the joints (r=0.40; p <0.001) and the intake duration of methotrexate (r=0.4; p <0.001) and glucocorticosteroids (r=0.3; p <0.05). The level of leptin in the blood serum of women with rheumatoid arthritis and healthy individuals was approximately the same. However, there were positive correlations between the level of leptin and of the tender joint count (r=0.5; p <0.0001), the levels of C-reactive protein (r=0.3; p <0.05) and interleukin-17 (r=0.3; p <0.05), the index Disease Activity Score 28 (r=0.4; p <0.001) and increased blood flow during Doppler imaging (r=0.4; p <0.001).Conclusion. Thus, patients with rheumatoid arthritis have a significant increase in the level of adiponectin compared to the health group, which is associated with pronounced destructive changes in the joints and the intake duration of methotrexate and glucocorticosteroids. However, a positive relationship between the indicators of disease activity and the presence of a Doppler signal is observed only in leptin.

Background:Disease modifying anti-rheumatic drugs (DMARD) can provide an unbalanced effect on individual components of the inflammatory process, which in some cases leads to an insufficiently correct assessment of the patient’s status when using composite activity indices [1].Objectives:To compare the results of the rituximab (RTX) efficacy assessment in patients with rheumatoid arthritis (RA) using different composite indices of disease activity.Methods:Patients with active RA observed in 23 medical centers of the Russian Federation were included. They were randomized into 2 groups in a 2:1 ratio. In the main group methotrexate (MTX) was prescribed at 15 mg per week and RTX infusions 600 mg on days 1 and 15. Patients in the control group received MTX 15 mg per week and placebo on days 1 and 15. If after 15 weeks 20% reduction of tender joint count (TJC) and swollen joint count (SJC) was not achieved, another DMARD was prescribed.Results:159 RA patients (131 women and 18 men) were included. The mean age of patients was 51.4±11.8 years, the median duration of RA – 2.8 [0.6; 5.8] years. At baseline DAS28, SDAI and CDAI in all cases assessed disease activity as high. 6 months after RTX administration DAS28 showed remission in 9%, low, moderate and high activity activity in 7%, 47% and 37% of cases, SDAI – in 7%, 12%, 34% and 47%, CDAI – in 7%, 11%, 30% and 52%, respectively. In the control group remission, low, moderate and high activity by DAS28 were revealed in 2%, 2%, 38% and 58%, by SDAI – in 2%, 4%, 35%, 59%, by CDAI – in 2%, 6%, 29%, 63% of patients respectively. After 6 months, in patients achieved the treatment target (remission or low activity) according to DAS28, SJC in 12 cases was 0, in 3 – 1 and in 1 – 2. TJC was 0 in 9 cases and in 7 patients ranged from 1 to 14. The level of C-reactive protein (CRP) in 14 cases was within the normal range and in 2 – increased. Erythrocyte sedimentation rate (ESR) was normal in all cases. SDAI after 6 months showed the target activity in 18 patients treated with RTX. In 12 of them the SJC was 0, in 4 – 1 and in 2 – 2. In 9 cases TJC was 0, in the rest patients it varied from 2 to 5. The level of CRP was normal in 15 patients, ESR – in all patients. CDAI met the target activity in 17 patients. In 12 of them, SJC was 0, in 3 – 1, in 2 – 2. The level of CRP was normal in 14, ESR – in all patients.Conclusion:Assessment of RTX efficacy with DAS28, SDAI, and CDAI in RA provided comparable number of patients who achieved remission or low disease activity 6 months after administration of the drug. The groups of patients who reached this target level of activity by DAS28, SDAI, and CDAI did not have significant differences in the values of main measures characterizing residual inflammatory activity, including SJC, TJC, ESR, and CRP.References:[1]Bastida C, Soy D, Ruiz-Esquide V, Sanmartí R, et al.

In Pregnancy

Abstract Background/Aims In rheumatoid arthritis (RA), musculoskeletal ultrasound (MSK-US) has greater sensitivity for the detection of active disease than clinical assessment using the DAS28 score, which is prone to false elevation by a spuriously high tender joint count (TJC) and/or visual analogue score (VAS) from non-RA causes. Thus, DAS28 may correlate poorly with MSK-US findings. In pregnancy, standardised disease activity of RA comprises calculation of the modified DAS28(3)CRP score, with removal of the VAS and ESR, both of which are confounded by pregnancy, and replacement with CRP; however, it is unknown whether non-specific musculoskeletal pain and/or peripheral oedema in (especially late) pregnancy might contribute to the TJC or swollen joint count (SJC) respectively and thus render this adapted score less reliable. Therefore, we conducted this study of pregnant RA patients and controls to assess the ability of the DAS28(3)CRP to detect disease activity compared with MSK-US. Methods Pregnant RA patients were recruited from the UCLH obstetric rheumatology clinic from September 2018 to March 2020. Patients underwent clinical assessment with DAS28(3)CRP and MSK-US longitudinally through pregnancy/post-partum. A control group of age-matched non-pregnant female RA patients was recruited from general rheumatology clinics and had equivalent assessments. MSK-US was undertaken using a Logiq S8. The standard protocol comprised 22-joint assessment of hands (dorsal longitudinal and transverse views of wrists, metacarpophalangeal and proximal interphalangeal joints). Quantification of Power Doppler (PD) signal was made as per the Outcome Measures in Rheumatoid Arthritis Clinical Trials (OMERACT) US definitions. PD scores were calculated as mean scores of all joints scanned. Statistical correlations were performed in SPSS using Spearman’s rank coefficient as data were non-normally distributed. Results A total of 45 MSK-US scans of pregnant/postpartum RA patients (N = 24, mean age 34.5+-3.6) were performed and compared to a control group of non-pregnant RA patients, who were scanned once each (N = 18, mean age 32.3+-5.2; p = 0.12). In the second (T2) and third trimester (T3) and the postpartum (PP), there was a significant positive correlation between DAS28(3)CRP and PD score (T2, ρ = 0.87 (p < 0.01); T3, ρ = 0.76 (p < 0.01); PP, ρ = 0.68 (p = 0.03)). Interestingly, each of these were stronger correlations than the equivalent comparison in non-pregnant RA patients (ρ = 0.51 (p = 0.03)). TJC also significantly positively correlated with PD score in each trimester of pregnancy and postpartum, but not in non-pregnant patients; difference between correlation coefficients was statistically significant for each trimester (T1, p < 0.01; T2, p = 0.05; T3, p = 0.05). Conclusion Interestingly, we found that that DAS28(3)CRP correlates better with PD signal on MSK-US in pregnancy than in non-pregnancy. Specifically, there was significantly better correlation of the TJC with PD score. It is unclear why non-inflammatory contributors to the TJC may be less prominent in pregnancy and further investigation is warranted. Disclosure C.

The aim of the work was to study the relationship between the body mass index (BMI) in longstanding rheumatoid arthritis (RA) and RA disease activity and functional indices. This study included 105 RA patients. For all patients, we recorded the presence of erosions on radiographs, the presence of subcutaneous nodules (SCN), the 28-tender joint count (TJC), 28-swollen joint count (SJC) scores, the visual analogue scale (VAS), physicians’ global assessments (PhGA), the erythrocyte sedimentation rate (ESR), and the rheumatoid factor (RF). The disease activity index (DAS28) and BMI were calculated and current treatment was recorded. Patients were divided into two groups: group I: BMI 25. Group I included 32 (30.5%) patients, whereas group II included 73 (69.5%) patients. There were statistically significant differences between the two groups regarding each of the following: SJC (p=0.006), erosions (p=0.006), DAS28 (p=0.016) and PhGA (p=0.007). All were higher in group I (underweight and normal) than in group II (overweight and obese). No statistically significant differences emerged regarding age (p=0.11), smoking (p=0.69), disease duration (p=0.46), TJC (p=0.14), SCN (p=1.00), HAQ (p=0.26), VAS (p=0.16), ESR (p=0.25), RF (p=0.54) and steroid cumulative dose (p=0.08). Low BMI in longstanding RA patients may indicate more active and erosive disease and it may be considered as a poor prognostic factor.

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.

Background:N-terminal pro-brain natriuretic peptide (NT-proBNP) is a recognized predictor of congestive heart failure (CHF) and cardiovascular death. Rheumatoid arthritis (RA) patients (pts) were shown to have higher NT-proBNP concentrations than in general population, but it remains unclear, whether NT-proBNP levels are related to RA duration, activity or treatment.Objectives:To investigate the effect of interleukin 6 receptor inhibitor - tocilizumab (TCZ) and JAK inhibitor - tofacitinib (TOFA) on NT-proBNP levels in RA pts during a 12-month (m) follow-up period.Methods:The study enrolled 60pts (50women/10men) with the lack of efficacy/resistance and/or intolerance of basic anti-inflammatory drugs (DMARDs); median age was 55[42;61] years, median disease duration 55[29;120]m, with moderate to high activity (DAS28-5,1[4,6;6,1], serum positivity for rheumatoid factor (RF)(85%)/ anti-cyclic citrullinated peptide antibodies (ACCP)(80%). The study did not include RA pts with CHF and clinically overt cardiovascular disease (CVD). Twenty nine RA pts received TCZ(8mg/kg) every 4 weeks: 61% received TCZ in combination with methotrexate (MTX), 35% - with low-dose glucocorticoids (GCs). Thirty one RA pts were prescribed oral TOFA at 5 mg BID with dose escalation to 10 mg BID in 8 (26%)pts. TOFA was used in combination with MTX in 90% pts, with GCs – in 29% pts. Pts treated with TCZ and TOFA were comparable in terms of age, sex, body mass index. RA activity rates (DAS28, SDAI, ESR, CRP) were higher in pts on TCZ -therapy compared with pts treated with TOFA. Echocardiography data and NT-proBNP levels using electrochemiluminescence method Elecsys proBNP II (Roche Diagnostics, Switzerland) were obtained at baseline and after 12m.Results:Significant positive changes in major disease activity, clinical and laboratory parameters were found in RA pts after 12 m of TCZ infusion and TOFA intake: remission (DAS28<2,6) was achieved in 54% and 39% pts, low activity levels (DAS28<3,2) – in 46% and 51% pts, respectively.The NT-proBNP levels were significantly higher in RA pts than in the control group (median 69,1 (37,9;105,8) pg/mL vs 55,3 (36,6;67,3) pg/mL,p<0.05).Six pts (10%) (three in each pts group) had NT-proBNP levels over 125pg/ml, but were asymptomatic and had unremarkable echocardiography.There was a good correlation between NT-proBNP level at baseline with age (r=0,55,p<0,001), SDAI (r=0,5, h=0,01), ACCP (r=0,23,p=0,01).Decrease of median NT-proBNP levels was documented after 12m of TCZ therapy (81,5[43,0;102,0]vs41,6[25,4;64,2]pg/ml (p<0,01) and after 12m TOFA therapy (66,1[30,5;105,0]vs16,8 [5,0;81,0]pg/ml,p=0,001).After 12m of TCZ correlations of ΔNT-proBNP were established with ΔESR (R=0,43;p<0,05], ΔСRP (R=0,46;p<0,05], ΔEe left ventricle (LV) (r=0,88,p=0,03).In the group of pts treated with TOFA ΔNT-proBNP level significantly correlated with the percentage change in DAS 28 (r=0,41,p=0,038), there was no direct correlation with changes in the parameters of the LV diastolic function.Conclusion:TCZ and TOFA treatment for 12 m reduced NT-proBNP levels in RA pts without clinically manifest CVD and CHF. Falling NT-proBNP concentrations are associated with positive dynamics of RA activity (DAS 28) and inflammatory markers (CRP, ESR), therefore allowing to suggest that increased NT-proBNP levels should be considered as a component of disease activity. Correlation between ΔNT-proBNP and ΔEeLF may be indicative as possible impact of these biomarkers on the LV diastolic function’s development in RA pts.Disclosure of Interests:None declared

Background:Musculoskeletal Ultrasonography (MSUS) is now a widely used tool for monitoring of rheumatoid arthritis (RA). Although there are many proposed sets of composite scores, a fixed set of joints may not be an ideal tool to assess a disease like RA, which affects many joints and tendons in different presentations. In previous study (1) U9 score was proven to be correlated with disease activity parameters.Objectives:To determine whether US assessment using U9 score is useful for monitoring response to treatment for RA or not?Methods:A prospective, multicenter study were conducted in period from July 2019 to December 2019. All recruited RA patients were subjected to: Disease activity assessment by clinical disease activity indices (CDAI and DAS28 ESR). Functional status assessment by (HAQ) and ultrasonographic assessment using U9 score which include 8 joints (bilateral wrists,2ndMCP,3RDMCP and knees) plus most clinically affected joint or tendon (one joint or one tendon). Most clinically affected joints from 48 joints. Any affected tendons could be choosing. All targeted joints were evaluated according to EULAR guidlines and by EULAR/ OMERACT combined score (0-3). Targeted tendons were scored (0-3).All patients received their treatment (biologic and non biologic DMARDs) according to the decision of the treating physicians. No specific therapy is needed. CDAI and DAS28 ESR, HAQ and U9 score were repeated after 3 months to detect the response to change after receiving the therapy.Results:One hundred and forty patients (23.6% were male) with mean age 39.26±11.30 were recruited from 4 tertiary referral university hospitals.There was a significant difference (<0.001) between the first and second visits as regards clinical, laboratory and ultrasonographic parameters. DAS 28 decreased form (5.29±1.21) to (3.95±0.99), ESR decreased from (42.12±15.24) to (26.84±12.32), HAQ2 improved from (0.652±0.350) to (0.510±0.237) and U9 total US score decreased from (13.56±5.18) to (8.02±4.28).There was significant correlation between U9 ultrasonographic score and clinical parameters at both visits (table 1).Table 1.correlation between U9 ultrasonographic score and clinical parameters.U9 at 1stvisitU9 at 2ndvisitDAS-28Pearson Correlation(P value)0.806<0.0010.790<0.001CDAIPearson Correlation(P value)0.787<0.0010.773<0.001HAQPearson Correlation(P value)0.431<0.0010.317<0.001We found that the most suitable cut-off value of U9 score to predict high disease activity was 11.5 (sensitivity 85.7% and specificity 80.6%), cut off value for moderate disease activity was 5.5(sensitivity 83.2% and specificity 88%) and cut off value for low disease activity was 3.5 (sensitivity of 83.3% and specificity 57.1%).

Assessment Of Disease Activity

Background:Valid assessment of disease activity leads to improvement of long-term outcomes in patients with inflammatory arthritis (1). Optical spectral transmission (OST) is a modern diagnostic tool able to assess the blood-specific absorption of light transmitted through a tissue, promising quantification of inflammation in the finger and wrist joints of patients with rheumatoid arthritis (RA) (commercial device: HandScan – Demcon/Hemics, The Netherlands) (2). Even though an increasing number of studies have evaluated diagnostic value of this new technology in RA patients (2,3), no data exist regarding psoriatic arthritis (PsA).Objectives:To examine for the first time the diagnostic value of OST in detecting inflammation in patients with PsA and to evaluate its relationship with disease activity markers and various epidemiological and anthropometric patient characteristics.Methods:OST-Measurements were performed in a group of PsA patients and a group of healthy controls. The difference between OST in the two groups was statistically examined and relationships of OST with clinical (tender / swollen joint counts, disease activity on a visual analogue scale) and serological disease activity markers were evaluated. Moreover, joint ultrasound (US) examinations were performed in a subgroup of PsA patients and OST associations with a Power Doppler- and a Grey Scale-US score were examined. Finally, relationships of OST with various anthropometric and epidemiologic parameters (BMI, hand-size, gender, age) were assessed.Results:We recruited 49 PsA patients [65.3% female; mean age 53.3 years (± 11.8 SD)] and 114 control subjects [77.2% female; mean age 46 years (± 12.8 SD)]. OST was statistically significantly higher in the patient group, compared to the control group [14.95 (12.04 - 17.18, IQR) vs. 10.31 (7.84 – 13.79, IQR); p<0.001]. OST correlated moderately-strongly with both examined US scores (Power Doppler-score: r = 0.5; p = 0.026 and Grey Scale-score: r = 0.52; p = 0.028). Moreover, OST showed a moderate, statistically significant association with C-reactive protein (CRP) (r = 0,298; p = 0,037). Finally, males had significantly higher OST values than females and OST associated moderately-weakly with body mass index (BMI) in the control group (rho = 0.24; p< 0.001).Conclusion:This is the first report of a possible diagnostic value of OST in patients with PsA. OST correlated with ultrasound and serological activity markers and may thus prove to be a useful tool of disease activity assessment, next to well established diagnostic modalities, such as the joint US. Correlations of OST with patient characteristics implicate the need to take also anthropometric and epidemiological patient characteristics into account when interprenting OST results in order to avoid confounding.References:[1]Katchamart W, et al.

Disease Activity Measures

Background:Progressive rheumatoid arthritis (RA) is responsible for joint damage causing disabilities with no agreement on which disease measures best predict radiographic progressionObjectives:We aimed to determine which disease activity measures including disease activity score (DAS), modified (M) DAS28 (CRP), clinical disease activity index (CDAI), and health assessment questionnaire disability index (HAQ-DI) best predict rapid radiographic progression (RRP) in early RA patients at baseline (BL) and 3 months.Methods:PREMIER data, a 2-year, multicenter, double-blind active comparator–controlled study with methotrexate (MTX) naïve RA patients and active disease <3 years, were used. Only patients in the MTX arm were analyzed. RRP was defined as change in modified total Sharp (mTSS) > 3.5 at month 12. Logistic regression analysis assessed impact of measures at BL and 3 months on RRP at 12 months. Best cut-off points of M-DAS28(CRP) was also estimated using area under the receiver operating characteristic curve.Results:149 patients were included: female (n=113; 75.8%), positive RF (n=127; 85.2%), mean (SD) age 52.9 (13.3) years, disease duration 0.8 (0.9) year, DAS28(CRP) 6.3 (0.9). After adjusting for potential confounders, only M-DAS28(CRP) at BL (adjOR=3.29; 95% CI: 1.70-6.36) and 3 months (adjOR=2.56; 95% CI: 1.43-4.56) strongly predicted RRP at 12 months. M-DAS28(CRP) 4.5 and 2.6 at BL and 3 months maximized sensitivity and specificity for prediction of RRP.Conclusion:M-DAS28(CRP) was a stronger predictor at BL and 3 months for RRP compared with other disease activity measures. Removing tender joint count and patient global assessment from DAS28(CRP) improves prediction of RRP.References:[1] Breedveld FC, Weisman MH, Kavanaugh AF, Cohen SB, Pavelka K, van Vollenhoven R, et al.

Radiographic Changes

Objectives: This study was undertaken as an attempt to assess radiographic temporomandibular joint (TMJ) changes in relation to rheumatoid factor (RF), anticitrullinated protein (ACCP) antibodies and disease activity score 28 (DAS28) in rheumatoid arthritis (RA) patients to find the best predictor of rheumatoid affection of the TMJ with the ultimate goal of maintaining TMJ function and preventing joint damage. Methods: 20 Rheumatoid Arthritis patients as well as 20 volunteers were included in this study. RA group were assessed for RF, ACCP, DAS28. Both groups were assessed by CBCT for TMJ dimensions and radiographic osteoarthritic changes. All data were statistically analyzed. Results: Rheumatoid Arthritis group showed significantly less condylar height and more radiographic osteoarthritic changes than the control group. RF showed no significant correlation with either TMJ measurements or TMJ radiographic osteoarthritic changes. ACCP showed significant inverse correlation with condylar height and anteroposterior (AP) dimensions, but non-significant relation with mediolateral dimension and radiographic osteoarthritic changes. DAS28 showed significant inverse correlation with condylar AP and mediolateral dimensions. It also showed significant correlation with flattening of the TMJ condylar head and flattening of the articular fossa. Patients with high and moderate disease activity showed significantly smaller AP TMJ dimension than patients with low disease activity. Disease activity showed statistically significant direct correlation with all osteoarthritic changes except for erosions of the glenoid fossa and condyle. Conclusion: Disease Activity Score28 score and disease activity are strong indicators of TMJ affection in RA patients when compared to RF and ACCP. ACCP is a better indicator of changes in condylar measurements than TMJ osteoarthritic changes. While RF is the least efficient indicator of TMJ involvement in RA patients.

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.
