Abstract
Introduction Rheumatoid arthritis activity is evaluated based on a physical examination of each of the joints. However, the joint examination is not standardized, and the techniques are variable and difficult to reproduce due to disagreements among examiners. Objective To recommend standardized joint examination techniques based on the modified RAND-UCLA appropriateness method. Methods A review of the literature was conducted to determine the items to be included in the joint examination; subsequently, a consensus of rheumatologists was achieved with the modified RAND-UCLA methodology to issue the recommendations. The diagnosis of RA and differential diagnoses were excluded. Results Two hundred fifteen rheumatologists were invited to participate. Five were included in the core group and 26 in the group of clinical experts. Clinical experience ranged between 2 and 25 years (mean 15.6 years; standard deviation 6.3 years). Most rheumatologists participated in all rounds (Round 1: 100%, Round 2: 61%, and Round 3: 61%). Of the 45 statements in the questionnaire assessing the examination techniques, 28 (62%) were retained. In addition, 6 other statements were included during the face-to-face meeting for a total of 34 final statements. Conclusion Physical examination techniques for joints that determine RA activity are heterogeneous and differ markedly in terms of several characteristics. A list of recommendations is proposed as a guide to improve and standardize the method for the physical examination of the joints. This standardization will improve the diagnosis and results for patients with RA and help health caregivers provide better treatment.

Reappraisal of bone scintigraphy as a new tool for the evaluation of disease activity in patients with rheumatoid arthritis. Sci Rep 2021; 11:21809. [PMID: 34750402 PMCID: PMC8575878 DOI: 10.1038/s41598-021-01104-w] [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: 01/23/2021] [Accepted: 10/19/2021] [Indexed: 11/08/2022] Open
Abstract
We aimed to compare the reliability of bone scintigraphy (BS) and fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)-derived parameters in the detection of active arthritis in 28-joint areas and evaluate the reliability of joint counts between BS and clinical assessment in patients with rheumatoid arthritis (RA). We enrolled 106 patients (67 in the development group and 39 in the validation groups) with active RA who underwent BS, 18F-FDG PET/computed tomography (CT), and clinical evaluation of disease activity. We compared the results of BS-derived joint assessment with those of PET-derived and clinical joint assessments. Subsequently we developed a disease activity score (DAS) using BS-positive joints and validated it in an independent group. The number of BS-positive joints in 28-joint areas significantly correlated with the swollen /tender joint counts (SJC/TJC) and PET-derived joint counts. A BS uptake score of 2 (strong positive) was significantly more sensitive compared with a BS uptake score of 1 (weak positive) in detecting a PET-positive joint among the 28-joints. After conducting multivariate analyses including erythrocyte sediment rate (ESR) and patient global assessment (PGA) in addition to BS-derived parameters, BS/DAS was obtained as follows: 0.056 × number of BS-positive joints in 28 joints + 0.012 × ESR + 0.030 × PGA. A significant correlation between BS/DAS and DAS28-ESR was confirmed in the validation group. Strong positive uptake of BS is sensitive and reproducible for the detection of active joints, and can complement the clinical assessment of disease activity in RA.

Abstract
AIMS To examine the effects of a tailored telehealth educational intervention on medication adherence and disease activity in discharged patients with rheumatoid arthritis (RA). DESIGN An un-blinded randomized controlled trial. METHODS A total of 92 eligible patients were recruited from January 2015-December 2015. Participants were randomly assigned to either the intervention (N = 46) or control group (N = 46). The intervention group received four educational sessions delivered through a telephone across a 12-week intervention. The content of the education mainly included: subject's knowledge about disease; treatment goals; the importance of taking medication correctly; side effect management; remembering to take medication. The control group received only standard care including discharge instructions. Outcome measures included medication adherence and disease activity. RESULTS The intervention group had significantly higher medication adherence compared with the control group at 12th and 24th week. There was no significant difference between two groups in disease activity at 12th and 24th week. CONCLUSIONS The telephone-delivered tailored educational intervention effectively improved medication adherence among discharged patients with rheumatoid arthritis. However, no significant benefits of the intervention on disease activity were detected. IMPACT Good medication adherence in rheumatoid arthritis patients contributes to controlling symptom and inflammation, preventing the progressive structural damage. This study demonstrated that the telehealth educational intervention could improve patients' medication adherence but did not have a direct impact on clinical condition in the short-term. The intervention for discharged patients with rheumatoid arthritis can be integrated into the clinical setting by the nursing staff as follow-up care. TRIAL REGISTRATION NUMBER ChiCTR-IPR-14005722.

Abstract
OBJECTIVE Clinical joint count assessment is important for detecting synovitis but its reliability is a subject of controversy. This study was undertaken to assess the correlation of positron emission tomography (PET)-derived parameters in 68 joints with disease activity and to compare the reliability of joint counts between PET with computed tomography (CT) and clinical assessment in patients with rheumatoid arthritis (RA). METHODS We enrolled 91 patients with active RA (69 in a development group and 22 in a validation group) who underwent concurrent 18 F-fluorodeoxyglucose (18 F-FDG)-PET-CT and clinical disease activity evaluation. PET-derived parameters were compared with disease activity assessed using clinical joint count parameters. A Disease Activity Score (DAS) using counts of PET-positive joints was developed, and then validation studies were performed in an independent group. RESULTS The number of PET-positive joints (of 28 and 68 joints) was significantly correlated with the swollen joint count (SJC) and tender joint count (TJC) and the DAS in 28 joints using the erythrocyte sedimentation rate (DAS28-ESR). Intraobserver and interobserver reliability of PET for the affected joint counts were excellent. Interobserver reliability between nuclear medicine physicians and rheumatologists was good for the SJC and TJC in both 28 joints and 68 joints. After multivariate analyses, including ESR and patient's global assessment of disease activity (PtGA) in addition to PET-derived parameters, the PET/DAS was derived as (0.063 × number of PET-positive joints in 28 joints) + (0.011 × ESR) + (0.030 × PtGA). A significant correlation between the PET/DAS and the DAS28-ESR was confirmed in the validation group (P < 0.001). CONCLUSION PET-CT could serve as a sensitive and reliable method in the evaluation of disease activity in RA patients, and may be applicable as a research tool, particularly in clinical trials.

Abstract
To summarize evidence concerning the articular examination needed to determine rheumatoid arthritis (RA) activity (follow-up or control) via a systematic review. A search of Medline, Embase, Lilacs, SciELO, the Web of Science, the National Technical Reports Library, and the reference lists of relevant studies through March 2017 was conducted using a systematic methodology to identify studies of patients with RA older than 18 years in which a detailed description of the physical examination or a description of the components of the articular examination was provided. Of 8322 references, 74 studies were included according to the selection criteria, and 6 references were ultimately included at the end of the review. Most of the included studies (n = 5) were associated with a moderate risk of bias. There was great variability among the studies and the articular examination methods used. Some studies presented the examination with a complete specification of the technique (n = 2), the consensus of rheumatologists (n = 2), or training through audiovisual materials and face-to-face courses (n = 2), but none of the studies explicitly showed the technique by which the physical examination was performed. Despite the importance of the clinical evaluation and physical examination of patients with RA for diagnosis, prognosis, clinimetrics, and follow-up, evidence concerning how to perform the articular examination is scarce.

Abstract
BACKGROUND Joint counts are central to the assessment of rheumatoid arthritis (RA) but reliability is an issue. OBJECTIVES To evaluate the reliability and agreement of joint counts (intra-observer and inter-observer) by health care professionals (physicians, nurses, and metrologists) and patients in RA, and the impact of training and standardization on joint count reliability through a systematic literature review. METHODS Articles reporting joint count reliability or agreement in RA in PubMed, EMBase, and the Cochrane library between 1960 and 2012 were selected. Data were extracted regarding tender joint counts (TJCs) and swollen joint counts (SJCs) derived by physicians, metrologists, or patients for intra-observer and inter-observer reliability. In addition, methods and effects of training or standardization were extracted. Statistics expressing reliability such as intraclass correlation coefficients (ICCs) were extracted. Data analysis was primarily descriptive due to high heterogeneity. RESULTS Twenty-eight studies on health care professionals (HCP) and 20 studies on patients were included. Intra-observer reliability for TJCs and SJCs was good for HCPs and patients (range of ICC: 0.49-0.98). Inter-observer reliability between HCPs for TJCs was higher than for SJCs (range of ICC: 0.64-0.88 vs. 0.29-0.98). Patient inter-observer reliability with HCPs as comparators was better for TJCs (range of ICC: 0.31-0.91) compared to SJCs (0.16-0.64). Nine studies (7 with HCPs and 2 with patients) evaluated consensus or training, with improvement in reliability of TJCs but conflicting evidence for SJCs. CONCLUSION Intra- and inter-observer reliability was high for TJCs for HCPs and patients: among all groups, reliability was better for TJCs than SJCs. Inter-observer reliability of SJCs was poorer for patients than HCPs. Data were inconclusive regarding the potential for training to improve SJC reliability. Overall, the results support further evaluation for patient-reported joint counts as an outcome measure.

Abstract
Composite disease activity scores are frequently used in daily practice as tools for treatment decisions in patients with rheumatoid arthritis (RA). If reliable, patient-reported disease activity may be time saving in the busy clinic. The objective was to examine the test-retest reliability of the Disease Activity Score 28 CRP (DAS28-CRP) with four variables (4v) and three variables (3v), the Simplified Disease Activity Index (SDAI) and the Clinical Disease Activity Index (CDAI) when based on patient self-assessment of tender and swollen joints and to examine the agreement between these scores and physician-derived scores. Thirty out-clinic RA patients with stable disease were included. A joint count was performed two times 1 week apart by the patient and by an experienced physician. Test-retest reliability was expressed as the least significant difference (LSD), as the LSD in percent of the mean score (%LSD) and as intra-individual coefficients of variation (CVi). Mean scores based on physician vs. patient joint counts (visit 1) were: DAS28-CRP(4v) 3.5 ± 1.0 vs. 3.6 ± 1.1 (not significant (NS)), DAS28-CRP(3v) 3.4 ± 0.9 vs. 3.5 ± 0.9 (NS), SDAI 14.2 ± 9.4 vs.14.1 ± 9.4 (NS) and CDAI 13.4 ± 9.3 vs. 13.3 ± 9.4 (NS). The LSDs (%LSD) for duplicate assessments of patient-derived scores (visit 2 vs. 1) were: DAS28-CRP(4v) 0.8 (23.2), DAS28-CRP(3v) 0.9 (25.2), SDAI 8.3 (59.9) and CDAI 8.4 (63.8). Similar LSDs were found for differences between duplicate assessments of physician-derived scores and for differences between physician and patient-derived scores. CVis for SDAI and CDAI were significantly higher than for DAS28-CRP(4v) and DAS28-CRP(3v) (p < 0.005). Patient- and physician-derived scores agreed closely on group level. On the individual level, the LSDs between patient- and physician-derived scores were considerable but corresponded to both patient and physician intra-observer LSDs. Thus, scores based on patient-performed joint counts may be an alternative to traditional physician-derived scores in patients with stable disease.

Abstract
OBJECTIVE Synovitis assessment through evaluation of swollen joints is integral in steering treatment decisions in rheumatoid arthritis (RA). However, there is high inter-observer variation. The objective was to assess if a short collegiate consensus would improve swollen joint agreement between rheumatologists and whether this was affected by experience. METHODS Eighteen rheumatologists from French university rheumatology units participated in three 30 minutes rounds over a half day meeting evaluating joint counts of RA patients in small groups, followed by short consensus discussions. Agreement was evaluated at the end of each round as follows: (i) global agreement of swollen joints (ii) swollen joint agreement according to level of experience of the rheumatologist (iii) swollen joint count and (iv) agreement of disease activity state according to the Disease Activity Score (DAS28). Agreement was calculated using percentage agreement and kappa. RESULTS Global agreement of swollen joints failed to improve (kappa 0.50 to 0.52) at the joint level. Agreement between seniors did not improve but agreement between newly qualified rheumatologists and their senior peer, which was initially poor (kappa 0.28), improved significantly (to 0.54) at the end of the consensus exercises. Concordance of DAS28 activity states improved from 71% to 87%. CONCLUSION Consensus exercises for swollen joint assessment is worthwhile and may potentially improve agreement between clinicians in clinical synovitis and disease activity state, benefit was mostly observed in newly qualified rheumatologists.

Abstract
Frequent monitoring of rheumatoid arthritis (RA) patients enables timely treatment adjustments and improved outcomes. Currently this is not feasible due to a shortage of rheumatologists. An optical spectral transmission device is presented for objective assessment of joint inflammation in RA patients, while improving diagnostic accuracy and clinical workflow. A cross-sectional, nonrandomized observational study was performed with this device. In the study, 77 proximal interphalangeal (PIP) joints in 67 patients have been analyzed. Inflammation of these PIP joints was also assessed by a rheumatologist with a score varying from 1 (not inflamed) to 5 (severely inflamed). Out of 77 measurements, 27 were performed in moderate to strongly inflamed PIP joints. Comparison between the clinical assessment and an optical measurement showed a correlation coefficient r=0.63, p<0.001, 95% CI [0.47, 0.75], and a ROC curve (AUC=0.88) that shows a relative good specificity and sensitivity. Optical spectral transmission measurements in a single joint correlate with clinical assessment of joint inflammation, and therefore might be useful in monitoring joint inflammation in RA patients.

Abstract
Developments in the understanding of the pathogenesis of rheumatoid arthritis (RA) and the introduction of targeted biologic therapies have greatly advanced the management of RA in clinical practice. The management of RA is now aimed at achieving remission, to prevent joint damage and disability. In particular, a critical period early in disease is recognised, in which early aggressive treatment with disease-modifying therapy is advocated. Although a state of remission is the ideal, this chapter discusses the difficulties which may arise in achieving this goal in patients with established disease. The evidence for best management, aimed at achieving clinical remission in established disease, is reviewed. The consequences of incomplete control of chronic inflammation in established disease, including pain, disability and co-morbidities (such as cardiovascular disease and osteoporosis), also pose a significant clinical challenge. The rationale for a multidisciplinary team approach in reducing the associated morbidity and mortality of the disease are examined.
