Objective. Color Doppler ultrasonography (CDUS) can detect inflammation in the vessel wall.No studies have evaluated the examination of the common carotid artery by CDUS in the diagnostics of giant cell arteritis (GCA). Our aim was to evaluate the combination of CDUS examination of the temporal, axillary, and common carotid arteries in the diagnosis of GCA. Methods. Patients ages >50 years who were referred to our department between April 2010 and October 2012 and suspected to have GCA were consecutively examined. A positive clinical evaluation for GCA 6 months after the first evaluation by 3 rheumatologists was considered as the gold diagnostic standard. All patients underwent CDUS of the temporal, axillary, and common carotid arteries. A biopsy of the temporal artery was performed for most patients. Results. A total of 88 patients were assessed. Forty-six patients were diagnosed to have GCA by the defined gold standard. Forty-eight patients had a positive CDUS of the temporal artery. Forty-six patients diagnosed with GCA had a positive CDUS of the temporal, common carotid, and axillary arteries (100% sensitivity) and 4 patients had a positive CDUS without having GCA (91% specificity). Among the 39 GCA patients that underwent a biopsy, vasculitis was observed in 26 patients (66%), yielding a sensitivity of 67% and a specificity of 95%. Conclusion. CDUS of the common carotid, axillary, and temporal arteries had an excellent sensitivity and high specificity to diagnose GCA. CDUS has the potential to replace biopsy in ordinary clinical care without compromising on sensitivity and specificity.
ObjectiveThe main objective of this study was to compare disease burden in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (ax-SpA).MethodsIn this cross-sectional study, all the RA (1093), PsA (365) and ax-SpA (333) patients who visited the out-patient clinic of the Hospital of Southern Norway Trust during the year 2013 were included; the RA patients all had a RA diagnosis verified by the treating rheumatologist, the PsA patients all fulfilled the ClASsification for Psoriatic ARthritis (CASPAR) criteria and the ax-SpA patients all fulfilled the Assessment of SpondyloArthritis international Society (ASAS) classification criteria for ax-SpA. Patient-reported health status, demographic variables, medications, and composite scores of disease activity were assessed. The main analyses were performed using General Linear Models adjusted for age, sex and multiple comparisons. Correlation analyses were performed using Spearman’s rho.ResultsThe reported pain, joint pain, patient’s global assessment and fatigue were similar in PsA and ax-SpA, but significantly lower in RA. The 28-joint Disease Activity Score (DAS28) (0.3±0.1, p = 0.003), Clinical Disease Activity Index (CDAI) (1.0±0.4, p = 0.028) and Routine Assessment of Patient Index Data 3 (RAPID3) (0.4±0.1, p = 0.004) were all significantly higher in PsA vs. RA. RAPID3 showed moderate to high correlation with DAS28 (rho = 0.521, p<0.001) and CDAI (rho = 0.768, p<0.001) in RA and PsA, and with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) (rho = 0.902, p<0.001) and Bath Ankylosing Spondylitis Functional Index (BASFI) (0.865, p<0.001) in ax-SpA and PsA.ConclusionIn conclusion, patient- reported outcome measures were similar in our population of PsA and ax-SpA patients, but significantly lower for the RA patients. Composite disease activity measures were lower in RA than in PsA and ax-SpA, but the magnitude of these differences was small and probably not of clinical significance. Our study indicates that disease burden in RA, PsA and ax-SpA may be more similar than previously demonstrated.
BackgroundFew studies have investigated prognostic factors for patients with sciatica, especially for patients treated without surgery. The aim of this study was to identify factors associated with non-success after 1 and 2 years of follow-up and to test the prognostic value of surgical treatment for sciatica.MethodsThe study was a prospective multicentre observational study including 466 patients with sciatica and lumbar disc herniation. Potential prognostic factors were sociodemographic characteristics, back pain history, kinesiophobia, emotional distress, pain, comorbidity and clinical examination findings. Study participation did not alter treatment considerations for the patients in the clinics. Patients reported on the questionnaires if surgery of the disc herniation had been performed. Uni- and multivariate logistic regression analyses were used to evaluate factors associated with non-success, defined as Maine–Seattle Back Questionnaire score of ≥5 (0–12) (primary outcome) and Sciatica Bothersomeness Index ≥7 (0–24) (secondary outcome).ResultsRates of non-success were at 1 and 2 years 44% and 39% for the main outcome and 47% and 42% for the secondary outcome. Approximately 1/3 of the patients were treated surgically. For the main outcome variable, in the final multivariate model non-success at 1 year was significantly associated with being male (OR 1.70 [95% CI; 1.06 − 2.73]), smoker (2.06 [1.31 − 3.25]), more back pain (1.0 [1.01 − 1.02]), more comorbid subjective health complaints (1.09 [1.03 − 1.15]), reduced tendon reflex (1.62 [1.03 − 2.56]), and not treated surgically (2.97 [1.75 − 5.04]). Further, factors significantly associated with non-success at 2 years were duration of back problems >; 1 year (1.92 [1.11 − 3.32]), duration of sciatica >; 3 months (2.30 [1.40 − 3.80]), more comorbid subjective health complaints (1.10 [1.03 − 1.17]) and kinesiophobia (1.04 [1.00 − 1.08]). For the secondary outcome variable, in the final multivariate model, more comorbid subjective health complaints, more back pain, muscular weakness at clinical examination, and not treated surgically, were independent prognostic factors for non-success at both 1 and 2 years.ConclusionsThe results indicate that the prognosis for sciatica referred to secondary care is not that good and only slightly better after surgery and that comorbidity should be assessed in patients with sciatica. This calls for a broader assessment of patients with sciatica than the traditional clinical assessment in which mainly the physical symptoms and signs are investigated.
BackgroundPatients with inflammatory joint diseases (IJD) have increased risk of cardiovascular disease (CVD). Our aim was to compare CVD risk profiles in patients with IJD, including rheumatoid arthritis (RA), axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) and evaluate the future risk of CVD.MethodsThe prevalence and numbers of major CVD risk factors (CVD-RFs) (hypertension, elevated cholesterol, obesity, smoking, and diabetes mellitus) were estimated in patients with RA, axSpA and PsA. Relative and absolute risk of CVD according to Systematic Coronary Risk Evaluation (SCORE) was calculated.ResultsIn total, 3791 patients were included. CVD was present in 274 patients (7.2%). Of those without established CVD; hypertension and elevated cholesterol were the most frequent CVD-RFs, occurring in 49.8% and 32.8% of patients. Patients with PsA were more often hypertensive and obese. Overall, 73.6% of patients had a minimum of one CVD-RF, which increased from 53.2% among patients aged 30 to <45 years, to 86.2% of patients aged 60 to ≤80 years. Most patients (93.5%) had low/moderate estimated risk of CVD according to SCORE. According to relative risk estimations, 35.2% and 24.7% of patients had two or three times risk or higher, respectively, compared to individuals with no CVD-RFs.ConclusionsIn this nationwide Norwegian project, we have shown for the first time that prevalence and numbers of CVD-RFs were relatively comparable across the three major IJD entities. Furthermore, estimated absolute CVD risk was low, but the relative risk of CVD was markedly high in patients with IJD. Our findings indicate the need for CVD risk assessment in all patients with IJD.Electronic supplementary materialThe online version of this article (doi:10.1186/s13075-017-1358-1) contains supplementary material, which is available to authorized users.
IntroductionIn the new millennium, clinical outcomes in patients with rheumatoid arthritis (RA) have improved. Despite a large number of register data, there is a lack of data reflecting the entire outpatient RA population, and in particular long-term data. The main aim of this study was to explore changes in clinical disease status and treatment in an RA outpatient clinic population monitored with recommended outcome measures over a 10-year period.MethodsStandard data collected included demographic data, erythrocyte sedimentation rate, C-reactive protein, clinical measures of disease activity (Disease Activity Score in 28 joint counts [DAS28], Clinical Disease Activity Index [CDAI], Simplified Disease Activity Index [SDAI] and global assessments) and patient-reported outcomes (measures of physical function, joint pain, fatigue, patient global assessment and morning stiffness). Treatment with disease-modifying antirheumatic drugs (DMARDs) was also recorded, as well as rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA) status.ResultsIn the RA population, the mean age was approximately 64 years and disease duration was 10–12 years. About 70 % were females; approximately 20 % were current smokers; and 65–70 % were positive for RF and ACPA. During follow-up, disease activity improved significantly. When we applied the DAS28, CDAI, SDAI and Boolean criteria for remission, the proportions of patients in remission increased from 21.3 %, 8.1 %, 5.8 % and 3.8 %, respectively, in 2004 to 55.5 %, 31.7 %, 31.8 % and 17.7 %, respectively, in 2013. The proportions of patients with DAS28, CDAI and SDAI low disease activity status were 16.0 %, 34.0 %, and 34.9 %, respectively, in 2004 and 17.8 %, 50.4 % and 50.8 %, respectively, in 2013. A significant improvement in patient-reported outcome was seen only for the full 10-years, but not for the last 4 years, of the study period. The proportion of patients taking synthetic (about 60 %) and biologic (approximately 30 %) DMARDs was stable over the last 4 years of the study period, with no significant change observed, whereas the proportion of patients being treated with prednisolone was reduced significantly from 61 % in 2010 to 54 % in 2013.ConclusionsThe encouraging data we present suggest that the vast majority of patients with RA monitored in outpatient clinics in the new millennium can expect to achieve a status of clinical remission or low disease activity.
