RESUMO

OBJECTIVE: The randomised placebo-controlled GLORIA (Glucocorticoid LOw-dose in RheumatoId Arthritis) trial evaluated the benefits and harms of prednisolone 5 mg/day added to standard care for 2 years in patients aged 65+ years with rheumatoid arthritis (RA). Here, we studied disease activity, flares and possible adrenal insufficiency after blinded withdrawal of study medication. METHODS: Per protocol, patients successfully completing the 2-year trial period linearly tapered and stopped blinded study medication in 3 months. We compared changes in disease activity after taper between treatment groups (one-sided testing). Secondary outcomes (two-sided tests) comprised disease flares (DAS28 (Disease Activity Score 28 joints) increase >0.6, open-label glucocorticoids or disease-modifying antirheumatic drug (DMARD) increase/switch after week 4 of tapering) and symptoms/signs of adrenal insufficiency. In a subset of patients from 3 Dutch centres, cortisol and ACTH were measured in spot serum samples after tapering. RESULTS: 191 patients were eligible; 36 met treatment-related flare criteria and were only included in the flare analysis. Mean (SD) DAS28 change at follow-up: 0.2 (1.0) in the prednisolone group (n=76) vs 0.0 (1.2) in placebo (n=79). Adjusted for baseline, the between-group difference in DAS28 increase was 0.16 (95% confidence limit -0.06, p=0.12). Flares occurred in 45% of prednisolone patients compared with 33% in placebo, relative risk (RR) 1.37 (95% CI 0.95 to 1.98; p=0.12). We found no evidence for adrenal insufficiency. CONCLUSIONS: Tapering prednisolone moderately increases disease activity to the levels of the placebo group (mean still at low disease activity levels) and numerically increases the risk of flare without evidence for adrenal insufficiency. This suggests that withdrawal of low-dose prednisolone is feasible and safe after 2 years of administration.

RESUMO

OBJECTIVES: To determine the causes of death and risk factors in systemic sclerosis (SSc). METHODS: Between 2000 and 2011, we examined the death certificates of all French patients with SSc to determine causes of death. Then we examined causes of death and developed a score associated with all-cause mortality from the international European Scleroderma Trials and Research (EUSTAR) database. Candidate prognostic factors were tested by Cox proportional hazards regression model by single variable analysis, followed by a multiple variable model stratified by centres. The bootstrapping technique was used for internal validation. RESULTS: We identified 2719 French certificates of deaths related to SSc, mainly from cardiac (31%) and respiratory (18%) causes, and an increase in SSc-specific mortality over time. Over a median follow-up of 2.3 years, 1072 (9.6%) of 11 193 patients from the EUSTAR sample died, from cardiac disease in 27% and respiratory causes in 17%. By multiple variable analysis, a risk score was developed, which accurately predicted the 3-year mortality, with an area under the curve of 0.82. The 3-year survival of patients in the upper quartile was 53%, in contrast with 98% in the first quartile. CONCLUSION: Combining two complementary and detailed databases enabled the collection of an unprecedented 3700 deaths, revealing the major contribution of the cardiopulmonary system to SSc mortality. We also developed a robust score to risk-stratify these patients and estimate their 3-year survival. With the emergence of new therapies, these important observations should help caregivers plan and refine the monitoring and management to prolong these patients' survival.

RESUMO

Skin involvement in SSc is an important marker of disease activity, severity and prognosis, making the assessment of skin a key issue in SSc clinical research. We reviewed the published data assessing skin involvement in clinical trials and summarized the major conclusions important in SSc clinical research. A systematic literature review identified randomized controlled trials using skin outcomes in SSc. Analysis examined the validity of the different skin measures based on literature findings. Twenty-two randomized controlled trials were found. The average study duration was 10.2 (s.d. 4.5) months, mean (s.d.) sample size 32.4 (32.6) and 26.7 (27.8) in intervention and control arms, respectively. The 17-site modified Rodnan skin score is a fully validated primary outcome measure in diffuse cutaneous SSc. Skin histology seems to be an appropriate method for evaluation of skin thickness. These findings have important implications for clinical trial design targeting skin involvement in SSc.

RESUMO

Patients with immune-mediated rheumatic disease-related calcinosis comprise a subgroup at risk of encountering a more severe clinical outcome. Early assessment is pivotal for preventing overall disease progression, as calcinosis is commonly overlooked until several years into the disease and is considered as a 'non-lethal' manifestation. This single-center retrospective study explored the prevalence, clinical associations, and impact on survival of subcutaneous calcinosis in 86 patients with immune-mediated rheumatic diseases (IMRD). Calcinosis predominantly appeared in individuals with longstanding disease, particularly systemic sclerosis (SSc), constituting 74% of cases. Smaller calcinosis lesions (≤1 cm) were associated with interstitial lung disease, musculoskeletal involvement, and digital ulcerations, while larger lesions (≥4 cm) were associated with malignancy, severe peripheral artery disease, and systemic arterial hypertension. The SSc calcinosis subgroup exhibited a higher mean adjusted European Scleroderma Study Group Activity Index score than those without. However, survival rates did not significantly differ between the two groups. Diltiazem was the most commonly used treatment, and while bisphosphonates reduced complications related to calcinosis, complete resolution was not achieved. The findings underscore current limitations in diagnosing, monitoring, and treating calcinosis, emphasizing the need for further research and improved therapeutic strategies to improve patient care and outcomes.

RESUMO

BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory disease of the joints affecting 1% of the world population. It has major impact on patients through disability and associated comorbidities. Current treatment strategies have considerably improved the prognosis, but recent innovations (especially biologic drugs and the new class of so-called "JAK/STAT inhibitors") have important safety issues and are very costly. Glucocorticoids (GCs) are highly effective in RA, and could reduce the need for expensive treatment with biologic agents. However, despite more than 65 years of clinical experience, there is a lack of studies large enough to adequately document the benefit/harm balance. The result is inappropriate treatment strategies, i.e. both under-use and over-use of GCs, and consequently suboptimal treatment of RA. METHODS: The GLORIA study is a pragmatic multicentre, 2-year, randomised, double-blind, clinical trial to assess the safety and effectiveness of a daily dose of 5 mg prednisolone or matching placebo added to standard of care in elderly patients with RA. Eligible participants are diagnosed with RA, have inadequate disease control (disease activity score, DAS28 ≥ 2.6), and are ≥ 65 years. The primary outcome measures are the time-averaged mean value of the DAS28 and the occurrence of serious adverse events or adverse events of special interest. During the trial, change in antirheumatic therapy is permitted as clinically indicated, except for GCs. Cost-effectiveness and cost-utility are secondary outcomes. The main challenge is the interpretation of the trial result with two primary endpoints and the pragmatic trial design that allows co-interventions. Another challenge is the definition of safety and the relative lack of power to detect differences between treatment groups. We have chosen to define safety as the number of patients experiencing at least one serious adverse event. We also specify a decision tree to guide our conclusion on the balance of benefit and harm, and our methodology to combat potential confounding caused by co-interventions. DISCUSSION: Pragmatic trials minimise impact on daily practice and maximise clinical relevance of the results, but analysis and interpretation of the results is challenging. We expect that the results of this trial are of importance for all rheumatologists who treat elderly patients with RA. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02585258 .

RESUMO

AIM: Adalimumab effectiveness on clinical, functional and work-related outcomes was evaluated in patients with active ankylosing spondylitis or psoriatic arthritis treated in routine clinical practice in central-eastern Europe. METHODS: Patients (n = 555) were followed for 12 months. Primary end point was percentage of patients with a treatment response (≥50% decrease from baseline in Bath Ankylosing Spondylitis Disease Activity Index or ≥1.2 point decrease from baseline in Disease Activity Index-28 joint for axial or peripheral symptoms, respectively). Functional status was evaluated by the Bath Ankylosing Spondylitis Functional Index and Health Assessment Questionnaire Disability Index. Working ability was evaluated by the Work Productivity and Activity Impairment Questionnaire - Specific Health Problem. RESULTS: 76.1% of patients with axial symptoms and 83.5% with peripheral symptoms achieved a treatment response. Frequency of extra-articular manifestations decreased. Improvements were observed in functional status and workability. No new safety signals were observed. CONCLUSION: Adalimumab was effective and well tolerated during real-world use in central-eastern Europe.

RESUMO

OBJECTIVE: To identify the particularities of the clinical phenotype of endothelial dysfunction in a lot of Romanian patients from a reference center and compare it to data reported by international registries. MATERIAL AND METHODS: 51 patients were included in a cross-sectional study. The patients were evaluated for the pattern of disease, main visceral involvement, serum markers of disease. RESULTS: 41.2% patients had history of digital ulcers, 27.45% had pulmonary arterial hypertension; cardiovascular involvement also included: diastolic dysfunction in 31.1% of the patients, global systolic dysfunction in 9.8%, rhythm and conduction disturbances in 19.6%, peripheral vascular disease in 19.6%. Scleroderma renal crisis was identified in 2 patients. CONCLUSION: Vascular complications are a major cause of morbidity and mortality in systemic sclerosis. Earlier therapeutic intervention demands improved screening and diagnosis in all cases.

RESUMO

OBJECTIVE: Vitamin D has pleiotropic effects including immunomodulatory, cardioprotective, and antifibrotic properties and is thus able to modulate the three main links in scleroderma pathogenesis. The aim of the study was to evaluate the level of vitamin D in patients with systemic sclerosis and to analyze the associations between the concentration of vitamin D and the features of systemic sclerosis. MATERIAL AND METHODS: Fifty-one consecutive patients were evaluated for visceral involvement, immunological profile, activity, severity scores, and quality of life. The vitamin D status was evaluated by measuring the 25hydroxy-hydroxyvitamin D serum levels. RESULTS: The mean vitamin D level was 17.06±9.13 ng/dL. Only 9.8% of the patients had optimal vitamin D levels; 66.66% of them had insufficient 25(OH)D levels, while 23.52% had deficient levels. No correlation was found between vitamin D concentration and age, sex, autoantibody profile, extent of skin involvement, or vitamin D supplementation. Vitamin D levels were correlated with the diffusing capacity of the lung for carbon monoxide (p=0.019, r=0.353), diastolic dysfunction (p=0.033, r=-0.318), digital contractures (p=0.036, r=-0.298), and muscle weakness (p=0.015, r=-0.377) and had a trend for negative correlation with pulmonary hypertension (p=0.053, r=-0.29). CONCLUSION: Low levels of vitamin D are very common in systemic sclerosis. Poor vitamin status seems to be related with a more aggressive disease with multivisceral and severe organ involvement, especially pulmonary and cardiac involvement.

RESUMO

AIM: Rheumatoid arthritis (RA) may influence not only abdominal fat, but also whole body adiposity, since it is associated with chronic inflammation and disability. The study aims to evaluate the whole body adiposity of RA patients and to assess potential influences of disease specific measures. METHODS: The study was designed to include Caucasian postmenopausal female RA patients and age-matched postmenopausal female controls. Each subject underwent on the same day clinical examination, laboratory tests, whole body dual X-ray absorptiometry (DXA) composition and physical activity estimation using a self-administered questionnaire. RESULTS: A total of 107 RA women and 104 matched controls were included. Compared to controls, the RA group had less physical activity and a higher prevalence of normal weight obesity. Overfat RA women had a significantly higher toll of inflammation, disease activity, glucocorticoid treatment and sedentary behavior. RA women with inflammation, glucocorticoid treatment and higher disease activity class had higher whole body and trunk adipose tissue indices and higher prevalence of overfat status. Glucocorticoid treatment, inflammation, disease duration and severity correlated with whole body adipose tissue and significantly predicted high adiposity content and overfat phenotypes. CONCLUSIONS: RA disease duration and severity are associated with higher whole body and regional adiposity. Low-dose glucocorticoid treatment seems to contribute to adiposity gain and redistribution. Clinicians may need to assess body composition and physical activity in RA patients in order to fully manage cardiovascular outcomes and quality of life.

RESUMO

OBJECTIVES: The aim of this study is to compare the long term results of the treatment of anterior instability of the shoulder. MATERIALS AND METHODS: The study included a total of 37 patients diagnosed with anterior instability of the shoulder, on the basis of clinical data (anamnesis, physical examination) and imaging (X-rays, MRI examination), operated in the Department of Orthopedics and Traumatology - Emergency University Hospital Bucharest, Romania, between 2009-2012. They were divided in 3 groups, according to the surgical technique used (open Bankart, arthroscopic Bankart and Bristow procedure), and the results were evaluated at 2 years postoperatively using Rowe and Constant scores. Statistical analysis was performed using one-way ANOVA test. RESULTS: There were no intra- or postoperative complications. No reluxations were recorded. Statistically significant differences (F> Fcrit; p <0.05) of the Constant score were recorded between the three groups on the range of movement variable, especially external rotation, their mean values being higher in the group treated arthroscopically compared to the other two groups. CONCLUSION: Arthroscopic shoulder stabilization surgery gives the best long time results in terms of functional recovery of the shoulder, objectified by Constant and Rowe scores. Data from the literature show a higher rate of recurrence after arthroscopic interventions, suggesting that the indications of this technique still requires further clarifications. It's required a more precise preoperative evaluation, in order to detect any lesions associated with Bankart lesion (bone defects of the anterior rim of glenoid, Hill-Sachs lesion, capsular laxity, rotator cuff tears, long head of biceps injuries). Mastering a surgical techniques is not always enough in order to obtain the best results. The choice of proper surgical technique for each patient, however, can significantly reduce the recurrence rate of shoulder dislocation.

RESUMO

OBJECTIVES: Previous studies of bone tissue in rheumatoid arthritis (RA) using dual X-ray absorptiometry (DXA) concentrated on regions of interest that were used to diagnose osteoporosis. This study aimed to compare the whole body bone tissue (wbBT) of RA patients with healthy subjects and to identify the RA variables which significantly predict wbBT. METHODS: The study was cross-sectionally designed to include postmenopausal RA patients and age-matched healthy female controls. All 107 RA patients and all 104 controls underwent clinical examination, laboratory tests and whole body DXA composition, which recorded total and regional bone indices. Non-parametric standard statistical test and regression models after data normalization were used to assess correlations, associations and differences. RESULTS: Compared to controls, RA patients had significantly lower whole body and regional bone mass (14.9 kg compared to 15.5 kg; p = 0.031). Disease duration (r = -0.402 ; p < 0.001), C-reactive protein (r = -0.279; p = 0.015) and inflammation (2.5% wbBT compared to 2.9%; p = 0.043), radiographic damage (14.3 kg compared to 16.2 kg; p < 0.001), disease activity scores (r = -0.275 ; p = 0.018 for HAQ) are significantly correlated/associated with lower wbBT. Clinical structural damage is associated with lower wbBT and it can significantly predict them (R2 = 0.014; p = 0.001), while glucocorticoid treatment, even in low doses, was associated with lower wbBT percent (2.6% compared to 2.8%; p = 0.045). Treatment with biologics was associated with a lower rate of whole body osteoporosis (0% compared to 22.2%; p = 0.013). CONCLUSIONS: The main associated factors with the generalized bone loss in female RA patients are disease duration and disease activity. Clinical structural damage is the most powerful predictor of the whole body bone loss. These results suggest a general disturbance of skeletal bone metabolism in RA and could explain a greater risk of fragility fractures of non-central sites (e.g. ribs, tibia, ankles etc.) compared to post-menopause osteoporosis.

RESUMO

OBJECTIVE: This longitudinal study aims to determine if statins inhibit the response to rituximab in rheumatoid arthritis (RA) patients. METHODS: 41 patients initiating rituximab were included; 17 patients were exposed to the combination of statins and rituximab. The total cholesterol, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were assessed. The clinical response was evaluated using Disease Activity Score (DAS28) and European League against Rheumatism (EULAR) response at 6 and 18 months. RESULTS: A tendency of increasing in DAS28 was observed in statin-exposed group but the correlation was very weak (at 18 months: r = 0.013, P = 0.952). The statin-exposed status was negatively and very weakly correlated with EULAR response at 6 months (r = -0.073, P = 0.661) and 18 months (r = -0.197, P = 0.244). There was a negative correlation between statin-exposed status and inflammatory markers values (ESR and CRP); however, the correlation was very weak. The use of statin did not influence the cardiovascular risk measured by modified Systematic Coronary Risk Evaluation (mSCORE). CONCLUSIONS: Long-term significant inhibitory effects of statins on rituximab treatment in RA have not been proved using clinical response scores or biologic markers.

RESUMO

Introduction. Atherosclerosis and osteoporosis share an age-independent bidirectional correlation. Rheumatoid arthritis (RA) represents a risk factor for both conditions. Objectives. The study aims to evaluate the connection between the estimated cardiovascular risk (CVR) and the loss of bone tissue in RA patients. Methods. The study has a prospective cross-sectional design and it includes female in-patients with RA or without autoimmune diseases; bone tissue was measured using whole body dual X-ray absorptiometry (wbDXA); CVR was estimated using SCORE charts and PROCAM applications. Results. There were 75 RA women and 66 normal women of similar age. The wbDXA bone indices correlate significantly, negatively, and age-independently with the estimated CVR. The whole body bone percent (wbBP) was a significant predictor of estimated CVR, explaining 26% of SCORE variation along with low density lipoprotein (P < 0.001) and 49.7% of PROCAM variation along with glycemia and menopause duration (P < 0.001). Although obese patients had less bone relative to body composition (wbBP), in terms of quantity their bone content was significantly higher than that of nonobese patients. Conclusions. Female patients with RA and female patients with cardiovascular morbidity have a lower whole body bone percent. Obese female individuals have higher whole body bone mass than nonobese patients.

RESUMO

Clinical response in patients with rheumatoid arthritis (RA) treated with biologic agents can be influenced by their pharmacokinetics and immunogenicity. The present study evaluated the concordance between serum drug and antidrug levels as well as the clinical response in RA patients treated with biological agents who experience their first disease exacerbation while being on a stable biologic treatment. 154 RA patients treated with rituximab (RTX), infliximab (IFX), adalimumab (ADL), or etanercept (ETN) were included. DAS28, SDAI, and EULAR response were assessed at baseline and reevaluated at precise time intervals. At the time of their first sign of inadequate response, patients were tested for both serum drug level and antidrug antibodies level. At the next reevaluation, patients retreated with RTX that had detectable drug level had a better EULAR response (P = 0.038) with lower DAS28 and SDAI scores (P = 0.01 and P = 0.03). The same tendency was observed in patients treated with IFX and ETN regarding EULAR response (P = 0.002 and P = 0.023), DAS28 score (P = 0.002 and P = 0.003), and SDAI score (P = 0.001 and P = 0.026). Detectable biologic drug levels correlated with a better clinical response in patients experiencing their first RA inadequate response while being on a stable biologic treatment with RTX, IFX, and ETN.

RESUMO

OBJECTIVES: To determine if mixed connective tissue disease (MCTD) can be considered an independent clinical entity, to compare 3 different classification criteria for MCTD (Kasukawa, Alarcón-Segovia, and Sharp), and to define predictors (clinical features and autoantibodies) of potential evolution toward other connective tissue diseases (CTDs). METHODS: One hundred sixty-one MCTD patients were evaluated retrospectively at the diagnosis and in 2008. They were classified, at the diagnosis, according to the 3 classification criteria of MCTD (Sharp, Alarcón-Segovia, and Kasukawa) and reclassified in 2008 according to their evolution. Statistical analyses were performed to find out predictors (clinical features and autoantibodies) of evolution into other CTDs. RESULTS: After a mean of 7.9 years of disease, 57.9% of patients still satisfied MCTD classification criteria of Kasukawa; 17.3% evolved into systemic sclerosis, 9.1% into systemic lupus erythematosus, 2.5% into rheumatoid arthritis, 11.5% was reclassified as affected by undifferentiated connective tissue disease, and 1.7% as suffering from overlap syndrome. Kasukawa's criteria were more sensitive (75%) in comparison to those of Alarcón-Segovia (73%) and Sharp (42%). The presence of anti-DNA antibodies (P = 0.012) was associated with evolution into systemic lupus erythematosus; hypomotility or dilation of esophagus (P < 0.001); and sclerodactyly (P = 0.034) with evolution into systemic sclerosis. CONCLUSIONS: MCTD is a distinct clinical entity but it is evident that a subgroup of patients may evolve into another CTD during disease progression. Initial clinical features and autoantibodies can be useful to predict disease evolution.

RESUMO

It was suggested that the immune system plays an important role at least in the amplification of the main elements in systemic sclerosis (SSc), an autoimmune disease with an incompletely elucidated pathogenesis. Elucidation of the mechanisms involved in the interaction between T and B cells, major players of the immune system, could contribute to a better understanding of some of clinical and pathological manifestations of SSc. Recently, abnormalities in Semaphorin 4D (Sema4D/CD100) or CD72, two contrareceptors involved in T and B cells cooperation, were associated with autoimmunity. Therefore, we investigated CD100 and CD72 expression level on T and B cells in attempting to establish their role in SSc pathogenesis. The results revealed augmented percentages of CD100(high) T and B cells, significantly increased expression of CD100 on CD4(+) T cells and frequently detectable levels of soluble CD100 in SSc patient sera compared to healthy donors. In SSc, CD100 dysregulations were associated with anti-Scl70 antibodies production, disease type, thickening of skin, disease duration, or with active inflammation processes. In consequence, dysregulations in CD100 expression and release could play a role in SSc development and/or maintenance.

RESUMO

BACKGROUND: Immunological abnormalities in rheumatoid arthritis (RA) imply several antibodies, among which anti-cyclic cytrullinated peptide antibodies (anti-CCP) have the highest sensitivity and specificity. Their diagnostic and prognostic value in RA is well known, although their value as markers of the disease activity has not been established yet. OBJECTIVES: The aim of this study is to evaluate the correlation between anti-CCP antibodies and RA activity which eventually leads to the best treatment of choice. PATIENTS AND METHODS: 217 consecutive patients hospitalized in the Department of Internal Medicine and Rheumatology, "Sf Maria" Clinical Hospital between 01.01-31.06 2007 were retrospectively studied. They were divided into two groups: group A-111 patients with RA (ACR criteria fulfilled) and group B-106 patients with other rheumatic diseases. The following parameters taken out of the patients files were studied: parameters of the clinical activity of disease (C reactive protein, fibrinogen), rheumatoid factor (RF) and anti-CCP antibodies. Disease activity score (DAS) using 4 variables (number of tender joints, number of swollen joints, erythrocyte sedimentation rate and assessement of the disease activity) was also studied. Data were processed with SPSS program using linear functions, Pearson correlation coefficient and Hi2 test of interdependency. RESULTS: The sensitivity of anti-CCP antibodies in patients with RA was 56.75%. The specificity of anti-CCP antibodies in patients with RA was 90.56%. Low seric levels of anti-CCP antibodies were also found in patients without RA, but with other conditions like: osteoarthritis, viral polyarthritis, infectious myositis and Still disease; moderate to high seric levels were found in patients with psoriatic arthritis. Significant correlations were found between anti-CCP antibodies and DAS (r = 0.437), between anti-CCP and fibrinogen (r = 0.32) between anti-CCP antibodies and C reactive protein (r = 0.237) as well as between anti-CCP and RF (r = 0.38). CONCLUSIONS: Anti-CCP antibodies are highly specific but moderately sensitive for RA, their highest frequencies and seric levels being found in seropositive RA. Anti-CCP can be used in patients with RA not only as a diagnostic marker but also as a reliable test for assessing the activity of the disease.

RESUMO

Sjögren's Syndrome (SS) is one of the most frequent autoimmune disorders, which affects approximately 1% of the population. It occurs in patients of all ages, but especially females during the fourth and fifth decades of life with a female/male ratio of 9:1. The main target of this disease are the exocrine glands that are infiltrated progressively by lymphocytes and finally destroyed, leading to decreased exocrine secretion. Thus primary SS is usually defined as xerophtalmia (dry eye) and xerostomia (dry mouth) accompanied in 60% of cases by parotid swelling [1]. The most serious complication of Sjögren's Syndrome is the high risk of the occurrence of non-Hodgkin's Lymphoma.
