Several new treatment modalities with different mechanisms of action have been studied in patients with Behçet's syndrome (BS). The aim of the current effort was to update the recommendations in the ...light of these new data under the auspices of the European League Against Rheumatism (EULAR) Standing Committee for Clinical Affairs. A task force was formed that included BS experts from different specialties including internal medicine, rheumatology, ophthalmology, dermatology, neurology, gastroenterology, oral health medicine and vascular surgery, along with a methodologist, a health professional, two patients and two fellows in charge of the systematic literature search. Research questions were determined using a Delphi approach. EULAR standardised operating procedures was used as the framework. Results of the systematic literature review were presented to the task force during a meeting. The former recommendations were modified or new recommendations were formed after thorough discussions followed by voting. The recommendations on the medical management of mucocutaneous, joint, eye, vascular, neurological and gastrointestinal involvement of BS were modified; five overarching principles and a new recommendation about the surgical management of vascular involvement were added. These updated, evidence-based recommendations are intended to help physicians caring for patients with BS. They also attempt to highlight the shortcomings of the available clinical research with the aim of proposing an agenda for further research priorities.
Ultrasonography of temporal arteries is not commonly used in the approach of patients with suspected giant cell arteritis (GCA) in clinical practice. A meta-analysis of primary studies available ...through April 2004 concluded that ultrasonography could indeed be helpful in diagnosing GCA. We specifically re-examined the diagnostic value of the ultrasonography-derived halo sign, a dark hypoechoic circumferential thickening around the artery lumen, indicating vasculitic wall edema, in GCA.
Original, prospective studies in patients with suspected GCA that examined ultrasonography findings of temporal arteries using the ACR 1990 classification criteria for GCA as reference standard, published through 2009, were identified. Only eight studies involving 575 patients, 204 of whom received the final diagnosis of GCA, fulfilled technical quality criteria for ultrasound. Weighted sensitivity and specificity estimates of the halo sign were assessed, their possible heterogeneity was investigated and pooled diagnostic odds ratio was determined.
Unilateral halo sign achieved an overall sensitivity of 68% (95% CI, 0.61-0.74) and specificity of 91% (95% CI, 0.88-0.94) for GCA. The values of inconsistency coefficient (I2) of both sensitivity and specificity of the halo sign, showed significant heterogeneity concerning the results between studies. Pooled diagnostic odds ratio, expressing how much greater the odds of having GCA are for patients with halo sign than for those without, was 34 (95% CI, 8.21-138.23). Diagnostic odds ratio was further increased to 65 (95% CI, 17.86-236.82) when bilateral halo signs were present (sensitivity/specificity of 43% and 100%, respectively). In both cases, it was found that DOR was constant across studies.
Temporal artery edema demonstrated as halo sign should be always looked for in ultrasonography when GCA is suspected. Providing that currently accepted technical quality criteria are fulfilled, halo sign's sensitivity and specificity are comparable to those of autoantibodies used as diagnostic tests in rheumatology. Validation of revised GCA classification criteria which will include the halo sign may be warranted.
Sporadic studies suggest hydroxychloroquine (HCQ) may be effective for thrombosis prevention in patients with primary antiphospholipid syndrome (PAPS) and may lead to antiphospholipid antibody (aPL) ...titer reduction but data from randomized studies are lacking.
We conducted a pilot open-label randomized prospective study aiming to evaluate the safety and efficacy of HCQ for thrombosis prevention in 50 patients with PAPS allocated 1:1 to HCQ plus standard care (systemic anticoagulation and/or antiplatelet therapy) vs. standard care alone, as well as the effect of HCQ on aPL titers of 50 PAPS patients and 15 asymptomatic aPL carriers.
HCQ use plus standard care was associated with lower incidence rate of thrombosis than standard care alone (0.001 vs. 0.007, log-rank p =0.048) over an average 2.6-year follow-up, and a multivariate hazard ratio of 0.09 (95% CI = 0.01–1.26, p = 0.074) after adjusting for the effect of age, sex, traditional cardiovascular risk factors, triple aPL positivity, history of recurrent thrombotic events at baseline, and poor anticoagulation quality (INR levels within therapeutic range for ≤80% of follow-up). No significant difference in safety outcomes was observed between the two groups. Long-term HCQ use was associated with a decrease in aPL titers except for IgM anticardiolipin antibodies, which tended to decrease overtime regardless of treatment allocation.
HCQ may represent an effective adjuvant treatment for thrombosis prevention in patients with PAPS, which may be mediated via a reduction in aPL titers. Larger randomized trials are needed in order to corroborate this finding and investigate the thromboprotective role of HCQ in asymptomatic aPL carriers.
•This is the first report of randomized hydroxychloroquine (HCQ) use for thrombosis prevention in primary antiphospholipid syndrome (PAPS)•PAPS patients allocated to HCQ in addition to standard care had lower incidence of thrombosis (1/25 vs 6/25, logrank p=.048)•In multiple cox regression adjusting for potential confounders, the hazard ratio for thrombosis with HCQ was 0.09 (p=.074)•Cumulative exposure to HCQ was associated with downtrending antibody titers in most aPL subtypes over a 3-year follow-up
To identify overall disease course, progression patterns and risk factors predictive for progressive interstitial lung disease (ILD) in patients with systemic sclerosis-associated ILD (SSc-ILD), ...using data from the European Scleroderma Trials And Research (EUSTAR) database over long-term follow-up.
Eligible patients with SSc-ILD were registered in the EUSTAR database and had measurements of forced vital capacity (FVC) at baseline and after 12±3 months. Long-term progressive ILD and progression patterns were assessed in patients with multiple FVC measurements. Potential predictors of ILD progression were analysed using multivariable mixed-effect models.
826 patients with SSc-ILD were included. Over 12±3 months, 219 (27%) showed progressive ILD: either moderate (FVC decline 5% to 10%) or significant (FVC decline >10%). A total of 535 (65%) patients had multiple FVC measurements available over mean 5-year follow-up. In each 12-month period, 23% to 27% of SSc-ILD patients showed progressive ILD, but only a minority of patients showed progression in consecutive periods. Most patients with progressive ILD (58%) had a pattern of slow lung function decline, with more periods of stability/improvement than decline, whereas only 8% showed rapid, continuously declining FVC; 178 (33%) experienced no episode of FVC decline. The strongest predictive factors for FVC decline over 5 years were male sex, higher modified Rodnan skin score and reflux/dysphagia symptoms.
SSc-ILD shows a heterogeneous and variable disease course, and thus monitoring all patients closely is important. Novel treatment concepts, with treatment initiation before FVC decline occurs, should aim for prevention of progression to avoid irreversible organ damage.
Cardiovascular disease (CVD) is the foremost cause of morbidity and deaths in antiphospholipid syndrome (APS), driven by thrombo-inflammation and atherothrombosis mechanisms. Metabolic syndrome ...(MetS) is a proinflammatory and prothrombotic state characterized by increased CVD risk. We aimed to evaluate the prevalence of MetS in APS patients compared to rheumatoid arthritis (RA) and diabetes mellitus (DM) and its associations with clinical and laboratory patient characteristics and vascular ultrasound (US) markers of subclinical atherosclerosis.
We included 414 patients in our study: 138 patients with APS (median age: 44.9 years, females 70%) and matched 1:1 for age and sex RA and DM subjects. Three sets of criteria were used for MetS diagnosis: Joint Interim Statement (JIS), International Diabetes Federation (IDF) and modified National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII). The demographic, clinical and laboratory characteristics of all participants were recorded and carotid and femoral US was performed in patients with APS. Multivariate regression models were applied.
Prevalence of MetS was 23.9%, 23.2%, 20.3% (based on JIS, IDF, modified NCEP-ATPIII criteria, respectively) in APS versus 17.4%, 17.4%, 13% in RA (p=0.181, p=0.231, p=0.106, respectively), and 44.2%, 44.2%, 40.6% in DM patients. In multivariate analysis, patients with systemic lupus erythematosus- related APS had an approximately 2.5-fold higher risk of MetS versus RA patients. MetS in APS was independently associated with arterial thrombosis (Odds ratio 3.5, p=0.030). Odds ratio for MetS was 1.16 for each one unit increase in C-reactive protein levels according to JIS and IDF criteria, and 1.49 and 1.47 for each one unit increase in uric acid levels using the IDF and modified NCEP-ATPIII models, respectively. APS patients with atherosclerotic carotid plaques had 4 to 6.5-fold increased risk of MetS. Odds for MetS were decreased by 26% with an increase in physical activity by one hour per week.
MetS is present in approximately one-fourth of APS patients at a comparable prevalence to that observed in patients with RA. MetS in APS is associated with arterial thrombosis, cardiovascular risk biomarkers, physical activity, and subclinical atherosclerosis, supporting its role in cardiovascular risk stratification and management in APS.
Objective Off-label use of anti-tumor necrosis factor (TNF) agents for Behçet's disease (BD) is increasing. We evaluated published data on their efficacy and safety for patients with unmet medical ...needs due to severe disease manifestations, including ocular, gastrointestinal, and central nervous system involvement. Methods Peer-reviewed articles on anti-TNF agents for BD appearing in Medline/PubMed through March 2010 were identified using the appropriate indexing terms. Results We found 88, 12, and 13 primary articles from 20 countries on infliximab, etanercept, and adalimumab, reporting on 325, 37, and 28 patients, respectively. All patients were inadequately controlled with, or intolerant to, other immunosuppressive regimens, including interferon; 20 patients received more than 1 anti-TNF agent. In the only randomized placebo-controlled trial, 4-week administration of etanercept was effective in suppressing most of the mucocutaneous manifestations. In 16 open prospective studies evaluating the effect of repetitive infliximab injections (174 patients in total, men:women = 3:1, median follow-up = 16.2 months), sustained organ-specific, clinical responses were evident in 90%, 89%, 100%, and 91% of patients with resistant mucocutaneous, ocular, gastrointestinal, and central nervous system involvement, respectively. Combination of infliximab with azathioprine and/or cyclosporine-A appeared superior to monotherapy for sustained ocular remission. However, due to the fact that necessary data were lacking, formal estimation of anti-TNF treatment effect on the disease activity indexes for different organ involvement was not possible. Conclusions Although more controlled data are needed, there is enough published experience to suggest that TNF blockade represents an important therapeutic advancement for patients with severe and resistant, or intolerant, to standard immunosuppressive regimens BD.
Abstract
Objectives
Cardiac magnetic resonance imaging (CMRI) is increasingly used to evaluate cardiac involvement in SSc. We assessed changes, including inflammatory and/or fibrotic myocardial ...lesions detected by CMRI, following therapeutic interventions for SSc-associated symptomatic myocarditis.
Methods
In this retrospective study, myocarditis was diagnosed by CMRI (2018 revised Lake Louise criteria) in 14 diffuse and 4 limited SSc patients 16/18 women, age 56 years (s.d. 11), disease duration 8 years (s.d. 11), 17/18 with lung involvement with cardiac symptoms and abnormal findings on echocardiography (4/18) and/or in 24-hour Holter monitoring (12/14). CMRI was repeated after 8 months (s.d. 3) following administration of cyclophosphamide (n = 11, combined with corticosteroids in 3 and rituximab in 1), mycophenolate (n = 1), tocilizumab (n = 1), methotrexate/corticosteroids (n = 2), corticosteroids (n = 1) or autologous stem cell transplantation (n = 2).
Results
Functional cardiac improvement was evident by increases in left by 5.8% (s.d. 7.8), P = 0.006 and right ventricular ejection fraction by 4.5% (s.d. 11.4), P = 0.085 in the second CMRI compared with the first. Notably, late gadolinium enhancement, currently considered to denote replacement fibrosis, decreased by 3.1% (s.d. 3.8; P = 0.003), resolving in six patients. Markers of myocardial oedema, namely T2 ratio and T2 mapping, decreased by 0.27 (s.d. 0.40; P = 0.013) and 6.0 (s.d. 7; P = 0.025), respectively. Conversely, both T1 mapping, considered to reflect acute oedema and diffuse fibrosis, and extracellular volume fraction, reflecting diffuse fibrosis, remained unchanged.
Conclusions
CMRI may distinguish between reversible inflammatory/fibrotic and irreversible fibrotic lesions in SSc patients with active myocarditis, confirming the unique nature of primary cardiac involvement in SSc. Whether, and how, CMRI should be used to monitor treatment effects in SSc-associated myocarditis warrants further study.
