RESUMO

The aim of the study was to evaluate the levels of physical activity in individuals with primary Sjögren's syndrome (PSS) and its relationship to the clinical features of PSS. To this cross-sectional study, self-reported levels of physical activity from 273 PSS patients were measured using the International Physical Activity Questionnaire-short form (IPAQ-SF) and were compared with healthy controls matched for age, sex and body mass index. Fatigue and other clinical aspects of PSS including disease status, dryness, daytime sleepiness, dysautonomia, anxiety and depression were assessed using validated tools. Individuals with PSS had significantly reduced levels of physical activity [median (interquartile range, IQR) 1572 (594-3158) versus 3708 (1732-8255) metabolic equivalent of task (MET) × min/week, p < 0.001], but similar levels of sedentary activity [median (IQR) min 300 (135-375) versus 343 (223-433) (MET) × min/week, p = 0.532] compared to healthy individuals. Differences in physical activity between PSS and controls increased at moderate [median (IQR) 0 (0-480) versus 1560 (570-3900) MET × min/week, p < 0.001] and vigorous intensities [median (IQR) 0 (0-480) versus 480 (0-1920) MET × min/week, p < 0.001]. Correlation analysis revealed a significant association between physical activity and fatigue, orthostatic intolerance, depressive symptoms and quality of life. Sedentary activity did not correlate with fatigue. Stepwise linear regression analysis identified symptoms of depression and daytime sleepiness as independent predictors of levels of physical activity. Physical activity is reduced in people with PSS and is associated with symptoms of depression and daytime sleepiness. Sedentary activity is not increased in PSS. Clinical care teams should explore the clinical utility of targeting low levels of physical activity in PSS.

RESUMO

OBJECTIVE: To identify numbers of participants in the UK Primary Sjögren's Syndrome Registry (UKPSSR) who would fulfil eligibility criteria for previous/current or potential clinical trials in primary SS (pSS) in order to optimize recruitment. METHODS: We did a retrospective analysis of UKPSSR cohort data of 688 participants who had pSS with evaluable data. RESULTS: In relation to previous/current trials, 75.2% fulfilled eligibility for the Belimumab in Subjects with Primary Sjögren's Syndrome study (Belimumab), 41.4% fulfilled eligibility for the Trial of Remicade in primary Sjögren's syndrome study (Infliximab), 35.4% for the Efficacy of Tocilizumab in Primary Sjögren's Syndrome study (Tocilizumab), 31.6% for the Tolerance and Efficacy of Rituximab in Sjögren's Disease study (Rituximab), 26.9% for the Trial of anti-B-cell therapy in pSS study (Rituximab) and 26.6% for the Efficacy and Safety of Abatacept in Patients With Primary Sjögren's Syndrome study (Abatacept). If recent measures of outcome, such as the EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) score ⩾5 (measure of patient symptoms) and the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) score ⩾5 (measure of systemic disease activity) are incorporated into a study design, with requirements for an unstimulated salivary flow >0 and anti-Ro positivity, then the pool of eligible participants is reduced to 14.3%. CONCLUSION: The UKPSSR identified a number of options for trial design, including selection on ESSDAI ⩾5, ESSPRI ⩾5 and serological and other parameters.

RESUMO

OBJECTIVE: This study sets out to investigate the relationship between health status [EuroQol five-dimensions questionnaire (EQ-5D)] in primary SS and three of the European League Against Rheumatism (EULAR) SS outcome measures-the disease activity index (ESSDAI), the patient reported index (ESSPRI) and the sicca score. In particular, the goal was to establish whether there is a relationship between the EULAR outcome measures and quality of life. METHODS: Health status was evaluated using a standardized measure developed by the EuroQol Group-the EQ5D. This permits calculation of two measures of health status: time trade-off (TTO) values and the EQ-5D visual analogue scale (VAS) scores. We used Spearman's rank correlation analysis to investigate the strength of association between health status and three EULAR measures of physician- and patient-reported disease activity in 639 patients from the UK primary SS registry (UKPSSR) cohort. RESULTS: This study demonstrates that the EULAR SS disease-specific outcome measures are significantly correlated with health outcome values (P < 0.001). Higher scores on the ESSDAI, EULAR sicca score and ESSPRI are associated with poorer health states-i.e. lower TTO values and lower VAS scores. While all three are significantly correlated with TTO values and EQ-5D VAS scores, the effect is strongest for the ESSPRI. CONCLUSION: This study provides further evidence supporting the use of ESSDAI, EULAR sicca score and ESSPRI measures in the clinic. We also discuss the need for disease-specific measures of health status and their comparison with standardized health outcome measures.

RESUMO

OBJECTIVES: EuroQoL-5 dimension (EQ-5D) is a standardised preference-based tool for measurement of health-related quality of life and EQ-5D utility values can be converted to quality-adjusted life years (QALYs) to aid cost-utility analysis. This study aimed to evaluate the EQ-5D utility values of 639 patients with primary Sjögren's syndrome (PSS) in the UK. METHODS: Prospective data collected using a standardised pro forma were compared with UK normative data. Relationships between utility values and the clinical and laboratory features of PSS were explored. RESULTS: The proportion of patients with PSS reporting any problem in mobility, self-care, usual activities, pain/discomfort and anxiety/depression were 42.2%, 16.7%, 56.6%, 80.6% and 49.4%, respectively, compared with 5.4%, 1.6%, 7.9%, 30.2% and 15.7% for the UK general population. The median EQ-5D utility value was 0.691 (IQR 0.587-0.796, range -0.239 to 1.000) with a bimodal distribution. Bivariate correlation analysis revealed significant correlations between EQ-5D utility values and many clinical features of PSS, but most strongly with pain, depression and fatigue (R values>0.5). After adjusting for age and sex differences, multiple regression analysis identified pain and depression as the two most important predictors of EQ-5D utility values, accounting for 48% of the variability. Anxiety, fatigue and body mass index were other statistically significant predictors, but they accounted for <5% in variability. CONCLUSIONS: This is the first report on the EQ-5D utility values of patients with PSS. These patients have significantly impaired utility values compared with the UK general population. EQ-5D utility values are significantly related to pain and depression scores in PSS.

RESUMO

Objectives: To report on fatigue in patients from the United Kingdom primary Sjögren's syndrome (pSS) registry identifying factors associated with fatigue and robust to assignable causes such as comorbidities and medications associated with drowsiness. Methods: From our cohort (n = 608), we identified those with comorbidities associated with fatigue, and those taking medications associated with drowsiness. We constructed dummy variables, permitting the contribution of these potentially assignable causes of fatigue to be assessed. Using multiple regression analysis, we modelled the relationship between Profile of Fatigue and Discomfort physical and mental fatigue scores and potentially related variables. Results: Pain, depression and daytime sleepiness scores were closely associated with both physical and mental fatigue (all p ≤ 0.0001). In addition, dryness was strongly associated with physical fatigue (p ≤ 0.0001). These effects were observed even after adjustment for comorbidities associated with fatigue or medications associated with drowsiness. Conclusions: These findings support further research and clinical interventions targeting pain, dryness, depression and sleep to improve fatigue in patients with pSS.This finding is robust to both the effect of other comorbidities associated with fatigue and medications associated with drowsiness.

RESUMO

BACKGROUND: Heterogeneity is a major obstacle to developing effective treatments for patients with primary Sjögren's syndrome. We aimed to develop a robust method for stratification, exploiting heterogeneity in patient-reported symptoms, and to relate these differences to pathobiology and therapeutic response. METHODS: We did hierarchical cluster analysis using five common symptoms associated with primary Sjögren's syndrome (pain, fatigue, dryness, anxiety, and depression), followed by multinomial logistic regression to identify subgroups in the UK Primary Sjögren's Syndrome Registry (UKPSSR). We assessed clinical and biological differences between these subgroups, including transcriptional differences in peripheral blood. Patients from two independent validation cohorts in Norway and France were used to confirm patient stratification. Data from two phase 3 clinical trials were similarly stratified to assess the differences between subgroups in treatment response to hydroxychloroquine and rituximab. FINDINGS: In the UKPSSR cohort (n=608), we identified four subgroups: Low symptom burden (LSB), high symptom burden (HSB), dryness dominant with fatigue (DDF), and pain dominant with fatigue (PDF). Significant differences in peripheral blood lymphocyte counts, anti-SSA and anti-SSB antibody positivity, as well as serum IgG, κ-free light chain, ß2-microglobulin, and CXCL13 concentrations were observed between these subgroups, along with differentially expressed transcriptomic modules in peripheral blood. Similar findings were observed in the independent validation cohorts (n=396). Reanalysis of trial data stratifying patients into these subgroups suggested a treatment effect with hydroxychloroquine in the HSB subgroup and with rituximab in the DDF subgroup compared with placebo. INTERPRETATION: Stratification on the basis of patient-reported symptoms of patients with primary Sjögren's syndrome revealed distinct pathobiological endotypes with distinct responses to immunomodulatory treatments. Our data have important implications for clinical management, trial design, and therapeutic development. Similar stratification approaches might be useful for patients with other chronic immune-mediated diseases.

RESUMO

OBJECTIVES: To assess the use of the Clinical EULAR Sjögren's Syndrome Disease Activity Index (ClinESSDAI), a version of the ESSDAI without the biological domain, for assessing potential eligibility and outcomes for clinical trials in patients with primary Sjögren's syndrome (pSS), according to the new ACR-EULAR classification criteria, from the UK Primary Sjögren's Syndrome Registry (UKPSSR). METHODS: A total of 665 patients from the UKPSSR cohort were analysed at their time of inclusion in the registry. ESSDAI and ClinESSDAI were calculated for each patient. RESULTS: For different disease activity index cut-off values, more potentially eligible participants were found when ClinESSDAI was used than with ESSDAI. The distribution of patients according to defined disease activity levels did not differ statistically (chi2 p = 0.57) between ESSDAI and ClinESSDAI for moderate disease activity (score ≥5 and <14; ESSDAI 36.4%; ClinESSDA 36.5%) or high disease activity (score ≥14; ESSDAI 5.4%; ClinESSDAI 6.8%). We did not find significant differences between the indexes in terms of activity levels for individual domains, with the exception of the articular domain. We found a good level of agreement between both indexes, and a positive correlation between lymphadenopathy and glandular domains with the use of either index and with different cut-off values. With the use of ClinESSDAI, the minimal clinically important improvement value was more often achievable with a one grade improvement of a single domain than with ESSDAI. We observed similar results when using the new ACR-EULAR classification criteria or the previously used American-European Consensus Group (AECG) classification criteria for pSS. CONCLUSIONS: In the UKPSSR population, the use of ClinESSDAI instead of ESSDAI did not lead to significant changes in score distribution, potential eligibility or outcome measurement in trials, or in routine care when immunological tests are not available. These results need to be confirmed in other cohorts and with longitudinal data.

RESUMO

OBJECTIVE: To develop a novel method for capturing the discrepancy between objective tests and subjective dryness symptoms (a sensitivity scale) and to explore predictors of dryness sensitivity. METHODS: Archive data from the UK Primary Sjögren's Syndrome Registry (n = 688) were used. Patients were classified on a scale from -5 (stoical) to +5 (sensitive) depending on the degree of discrepancy between their objective and subjective symptoms classes. Sensitivity scores were correlated with demographic variables, disease-related factors, and symptoms of pain, fatigue, anxiety, and depression. RESULTS: Patients were on average relatively stoical for both types of dryness symptoms (mean ± SD ocular dryness -0.42 ± 2.2 and -1.24 ± 1.6 oral dryness). Twenty-seven percent of patients were classified as sensitive to ocular dryness and 9% to oral dryness. Hierarchical regression analyses identified the strongest predictor of ocular dryness sensitivity to be self-reported pain and that of oral dryness sensitivity to be self-reported fatigue. CONCLUSION: Ocular and oral dryness sensitivity can be classified on a continuous scale. The 2 symptom types are predicted by different variables. A large number of factors remain to be explored that may impact symptom sensitivity in primary Sjögren's syndrome, and the proposed method could be used to identify relatively sensitive and stoical patients for future studies.

RESUMO

Musculoskeletal conditions are common in general practice, but clinicians express poor self confidence in dealing with them. Training in general practice relies on clinical exposure to a range of presentations in order to gain competence. It has been suggested that trainees are exposed to a different case mix from qualified general practices (GPs), due to seeing more minor illness and less chronic disease and that this may be responsible in part for their subsequent lack of confidence. The aims of this study were to analyse the case mix of musculoskeletal conditions encountered by general practice trainees and to compare this to the overall population consulting behaviour. This is a prospective observational study. Thirteen general practices in North East England were recruited. Musculoskeletal disorders encountered by 13 GP trainees (7 junior and 6 senior) were prospectively recorded using a handheld diary. Disorders were classified according to working diagnosis or body region if diagnosis was unclear. Musculoskeletal (MSK) disorders comprised 17 % of consultations, and the distribution of diagnoses of these was in proportion to epidemiological studies of MSK disorders in the UK as they present in primary care. Back pain was the most frequent label with 141 (29 %) consultations with a further 43 (9 %) for neck pain. Inflammatory arthritis accounted for the same number 43 (9 %). Individual joint problems were 115 (24 %) with knee being most common. A specific diagnosis was more likely to be applied when symptoms were more distal and less likely when axial. Trainees are exposed to the same spectrum of MSK disorders as are present in the population as a whole. Case mix does not appear to be a significant factor in low confidence levels in dealing with MSK disorders.

RESUMO

OBJECTIVES: This article reports relationships between serum cytokine levels and patient-reported levels of fatigue, in the chronic immunological condition primary Sjögren's syndrome (pSS). METHODS: Blood levels of 24 cytokines were measured in 159 patients with pSS from the United Kingdom Primary Sjögren's Syndrome Registry and 28 healthy non-fatigued controls. Differences between cytokines in cases and controls were evaluated using Wilcoxon test. Patient-reported scores for fatigue were evaluated, classified according to severity and compared with cytokine levels using analysis of variance. Logistic regression was used to determine the most important predictors of fatigue levels. RESULTS: 14 cytokines were significantly higher in patients with pSS (n=159) compared to non-fatigued healthy controls (n=28). While serum levels were elevated in patients with pSS compared to healthy controls, unexpectedly, the levels of 4 proinflammatory cytokines-interferon-γ-induced protein-10 (IP-10) (p=0.019), tumour necrosis factor-α (p=0.046), lymphotoxin-α (p=0.034) and interferon-γ (IFN-γ) (p=0.022)-were inversely related to patient-reported levels of fatigue. A regression model predicting fatigue levels in pSS based on cytokine levels, disease-specific and clinical parameters, as well as anxiety, pain and depression, revealed IP-10, IFN-γ (both inversely), pain and depression (both positively) as the most important predictors of fatigue. This model correctly predicts fatigue levels with reasonable (67%) accuracy. CONCLUSIONS: Cytokines, pain and depression appear to be the most powerful predictors of fatigue in pSS. Our data challenge the notion that proinflammatory cytokines directly mediate fatigue in chronic immunological conditions. Instead, we hypothesise that mechanisms regulating inflammatory responses may be important.

RESUMO

BACKGROUND: Fatigue is a debilitating condition with a significant impact on patients' quality of life. Fatigue is frequently reported by patients suffering from primary Sjögren's Syndrome (pSS), a chronic autoimmune condition characterised by dryness of the eyes and the mouth. However, although fatigue is common in pSS, it does not manifest in all sufferers, providing an excellent model with which to explore the potential underpinning biological mechanisms. METHODS: Whole blood samples from 133 fully-phenotyped pSS patients stratified for the presence of fatigue, collected by the UK primary Sjögren's Syndrome Registry, were used for whole genome microarray. The resulting data were analysed both on a gene by gene basis and using pre-defined groups of genes. Finally, gene set enrichment analysis (GSEA) was used as a feature selection technique for input into a support vector machine (SVM) classifier. Classification was assessed using area under curve (AUC) of receiver operator characteristic and standard error of Wilcoxon statistic, SE(W). RESULTS: Although no genes were individually found to be associated with fatigue, 19 metabolic pathways were enriched in the high fatigue patient group using GSEA. Analysis revealed that these enrichments arose from the presence of a subset of 55 genes. A radial kernel SVM classifier with this subset of genes as input displayed significantly improved performance over classifiers using all pathway genes as input. The classifiers had AUCs of 0.866 (SE(W) 0.002) and 0.525 (SE(W) 0.006), respectively. CONCLUSIONS: Systematic analysis of gene expression data from pSS patients discordant for fatigue identified 55 genes which are predictive of fatigue level using SVM classification. This list represents the first step in understanding the underlying pathophysiological mechanisms of fatigue in patients with pSS.

RESUMO

BACKGROUND: Night pain is a significant problem for many patients with rheumatoid arthritis (RA), but clinicians often overlook it. This study aimed to explore the issue of night pain among patients with RA both at home and in the hospital setting. METHODS: This was a qualitative study involving in-depth interviews among 8 hospital inpatients with established RA. Each interview was recorded, transcribed, and underwent framework analysis. RESULTS: The following themes were identified: Night pain in RA is a significant problem both at home and in hospital. All patients had established routines that they used in the home setting when disturbed by night pain. This often included getting out of bed and walking around, making hot drinks, and/or taking extra painkillers. These activities were often curtailed in the hospital setting for fear of disturbing other patients or the nurses. The effect of disturbed sleep and night pain on other people, be it partners or family members at home or patients and nurses in the hospital, was raised by all interviewees. CONCLUSION: Night pain in particular appears harder to control in the hospital setting than at home, and some of this may stem from lack of a tailored routine and fears of disturbing others. Information could be provided when patients are first admitted to the ward. This could describe or orient patients to the facilities available, which may be beneficial in the management of night pain. Further work on identifying influences upon night pain needs to be undertaken.

RESUMO

OBJECTIVE: Objective structured clinical examination (OSCE) is a key part of medical student assessment. Currently, assessment is performed by medical examiners in situ. Our objective was to determine whether assessment by videotaped OSCE is as reliable as live OSCE assessment. METHODS: Participants were 95 undergraduate medical students attending their musculoskeletal week at Freeman Hospital, Newcastle (UK). Student performance on OSCE stations for shoulder or knee examinations was assessed by experienced rheumatologists. The stations were also videotaped and scored by a rheumatologist independently. The examinations consisted of a 14-item checklist and a global rating scale (GRS). RESULTS: Mean values for the shoulder OSCE checklist were 17.9 by live assessment and 17.4 by video (n = 50), and 20.9 and 20.0 for live and video knee assessment, respectively (n = 45). Intraclass correlation coefficients for shoulder and knee checklists were 0.55 and 0.58, respectively, indicating moderate reliability between live and video scores for the OSCE checklists. GRS scores were less reliable than checklist scores. There was 84% agreement in the classification of examination grades between live and video checklist scores for the shoulder and 87% agreement for the knee (kappa = 0.43 and 0.51, respectively; P < 0.001). CONCLUSION: Video OSCE has the potential to be reliable and offers some advantages over live OSCE including more efficient use of examiners' time, increased fairness, and better monitoring of standards across various schools/sites. However, further work is needed to support our findings and to implement and evaluate the quality assurance issues identified in this work before justifiable recommendations can be made.

RESUMO

OBJECTIVE: To evaluate the performance of biochemical and traditional markers in predicting radiographic progression in rheumatoid arthritis (RA). METHODS: One hundred thirty-two patients with early RA were treated with nonbiologic therapies for 2 years and studied longitudinally. Genomic DNA was analyzed for presence of the shared epitope. Levels of matrix metalloproteinases (matrix metalloproteinase 1 [MMP-1], MMP-13, and MMP-3), tissue inhibitor of metalloproteinases 1 (TIMP-1), and cartilage oligomeric matrix protein (COMP) were assessed in serially obtained serum samples. The presence of pyridinoline (Pyr), deoxypyridinoline, glycosylated Pyr (Glc-Gal-Pyr), and C-telopeptide of type II collagen (CTX-II) was assessed in urine samples. Radiographs obtained at entry and at 2 years were evaluated using the modified Larsen score. RESULTS: Baseline and 2-year radiographs were available from 118 patients. Larsen scores worsened during the 2 years in 50 patients, while 68 patients had no radiographic progression. Levels of a variety of biochemical markers, i.e., MMP-3, CTX-II, COMP, TIMP-1, Pyr, and Glc-Gal-Pyr, correlated significantly with radiographic progression at entry and longitudinally as assessed by area under the curve (AUC). By multivariate analysis, a model including MMP-3 and CTX-II was identified as providing the best prediction of radiographic progression at entry (predictive accuracy by receiver operating characteristic [ROC] AUC = 0.76 [95% confidence interval 0.66-0.85]), while a combination of MMP-3, CTX-II, and swollen joint count formed the best longitudinal AUC model (predictive accuracy by ROC AUC = 0.81 [95% confidence interval 0.73-0.89]). Patient-reported measures (Health Assessment Questionnaire, pain scores) were of limited use. In a subset of 50 patients who were treated with methotrexate (MTX) during the followup period, median serum MMP-3 levels decreased after the initiation of MTX therapy (P = 0.0003). CONCLUSION: These results indicate that biochemical markers are useful predictors of radiographic progression in RA and that serum MMP-3 levels decrease significantly with MTX therapy. Multivariate models that include MMP-3 and CTX-II perform better than existing traditional markers in predicting radiographic outcome in RA.

RESUMO

CONTEXT: Self-assessment promotes reflective practice, helps students identify gaps in their learning and is used in curricular evaluations. Currently, there is a dearth of validated self-assessment tools in rheumatology. We present a new musculoskeletal self-assessment tool (MSAT) that allows students to assess their confidence in their skills in and knowledge of knee and shoulder examination. OBJECTIVES: We aimed to validate the 15-item MSAT, addressing its construct validity, internal consistency, responsiveness, repeatability and relationship with competence. METHODS: Participants were 241 Year 3 students in Newcastle upon Tyne and 113 Year 3 students at University College London, who were starting their musculoskeletal skills placement. Factor analysis explored the construct validity of the MSAT; Cronbach's alpha assessed its internal consistency; standardised response mean (SRM) evaluated its responsiveness, and test-retest, before and after a pathology lecture, assessed its repeatability. Its relationship with competence was explored by evaluating its correlation with shoulder and knee objective structured clinical examinations (OSCEs). Results The MSAT was valid in distinguishing the 5 domains it intended to measure: clinical examination of the knee; clinical examination of the shoulder; clinical anatomy of the knee and shoulder; history taking, and generic musculoskeletal anatomical and clinical terms. It was internally consistent (alpha = 0.93), responsive (SRM 0.6 in Newcastle and 2.2 in London) and repeatable (intraclass correlation coefficient 0.97). Correlations between MSAT scores and OSCE scores were weak (r < 0.2). CONCLUSIONS: The MSAT has strong psychometric properties, thereby offering a valid approach to evaluating the self-assessment of confidence in examination skills by students. Confidence does not necessarily reflect competence; future research should clarify what underpins confidence.

RESUMO

The aim of this study was to explore which regional musculoskeletal examination skills medical students should learn and be examined on. A qualitative research study was undertaken, and six focus groups were formed involving 36 consultants from four chosen specialties. The feeling was that greater emphasis should be placed on the functional assessment of a patient. Students should be able to discern through examination what the patient can and cannot do with his/her affected limb/joint. It was felt that many of the traditional eponymously named special tests (e.g.Thomas' test, Trendelenburg's test) should be dispensed with along with traditional descriptions such as varus, valgus, swan neck and Boutonniere deformities. It was felt these were often a cause of confusion for medical undergraduates. A broad view and diversity in opinions was detected with differences between specialties. The strongest theme to emerge by far was the desire to simplify and standardize the regional examination as much as possible.
