RESUMEN
METHODS: This study reviewed the medical records of patients from the REMICAM cohort, a multicentric longitudinal study carried out in patients with IIM, followed up between 1980 and 2014 in 12 hospitals in Madrid, Spain. Patients with definite or probable JPM, JDM, adult DM, and adult PM according to the modified Bohan and Peter criteria were selected. We compared the characteristics between JDM and JPM, and between JIIM and adult IIM. RESULTS: Eighty-six juvenile patients (75 JDMs and 11 JPMs) and 283 adult patients (133 DMs and 150 PMs) were included. Compared with patients with JDM, patients with JPM were older at diagnosis, had more fever and arthritis, and were less frequently treated with disease-modifying antirheumatic drugs (these differences were not statistically significant). Compared with patients with adult DM, those with JDM presented more frequently with calcinosis (33.8% vs 6.9%, p < 0.0001) and had less severe infections (4.3% vs 23.4%, p < 0.0001), malignancies (1.3% vs 25.6%, p < 0.0001), and mortality (3.5% vs 33%, p < 0.0001). Patients with JDM were treated less frequently with azathioprine (10.8% vs 44.7%, p < 0.0001). CONCLUSIONS: Our findings confirm that JIIMs are a heterogeneous group of diseases with relevant differences compared with adult IIMs.

OBJECTIVES: To describe differences in clinical presentation between men and women in a large group of patients with early (<3 years' duration) systemic sclerosis (SSc) according to disease subsets. METHODS: A cross-sectional analysis of the prospective EULAR Scleroderma Trial and Research database (EUSTAR) was performed. Patients fulfilling preliminary ACR 1980 classification criteria for SSc, with less than 3 years from the first non-Raynaud's symptom at first entry, were selected. A group of patients with less than 3 years from the first SSc symptom, including Raynaud's phenomenon, was also analysed. SSc related variables, including antibodies, SSc subsets, disease activity and organ involvement were included. Descriptive and bivariate analyses were performed. RESULTS: A total of 1,027 patients were included, 90% Caucasian, 80% women, and 40% with diffuse cutaneous disease. In early stages of SSc, men showed more frequently than women active disease, diffuse cutaneous subset, anti-Scl-70 antibodies, elevated acute phase reactants, muscular and pulmonary involvement. Differences between men and women were confirmed in the limited, but not in the diffuse SSc subset. The results were similar when 650 patients with less than three years from the first SSc symptom, including Raynaud's phenomenon, were analysed. CONCLUSIONS: In early stages of SSc, men present signs and symptoms of more severe disease. In the limited disease subset, men might appear with clinical features and organ involvement similar to those of the diffuse subgroup. In clinical practice, the identification of such differences might help to select the appropriate management for each particular patient.

OBJECTIVE: To analyze the performance of the 1980 ACR and new 2013 ACR/EULAR criteria for systemic sclerosis (SSc) in cutaneous SSc (lcSSc) patients, especially those affected by lcSSc and pulmonary arterial hypertension (PAH). METHODS: All patients with a clinical lcSSc diagnosis from a prospective observational SSc cohort were included. Sociodemographic and disease-related variables were collected, and PAH confirmed by right heart catheterization (RHC). Performance of the 2013 and 1980 SSc criteria was analyzed in terms of clinical diagnosis. Descriptive and between-group analyses were performed as to the fulfillment of criterion sets, including comparison of survival. RESULTS: Overall, 321 patients were included, 63% of whom fulfilled the 1980 ACR and 93% the 2013 ACR/EULAR criteria. Agreement between both criteria sets proved poor (κ = 0.23). LcSSC patients fulfilling both criterion sets were significantly younger at diagnosis, whilst presenting organ involvement, calcinosis, fingertip digital ulcers, and pitting scars more frequently than those who met the 2013 criteria only. Patients who fulfilled the 2013 but not the 1980 criteria presented a higher degree of ACA positivity and PAH. Nearly 12% of patients developed PAH. Patients who did not meet the 1980 criteria were affected by a milder disease from but demonstrated higher pulmonary vascular resistance and lower cardiac index than those fulfilling both criterion sets. Whereas patients with PAH met the 2013 criteria, only 47% fulfilled the 1980 criteria. Regardless of criterion set fulfillment, high mortality was observed in PAH patients, with no significant between-patient difference based on criterion set. CONCLUSION: The new 2013 ARC/EULAR criteria prove more accurate than the former 1980 ACR criteria in identifying and differentiating patients with lcSSc, especially those with associated PAH. Since PAH exhibits a better prognosis if treated early, all SSc patients should undergo PAH screening.

OBJECTIVES: To explore the prevalence and clinical associations of elevated systolic pulmonary artery pressure (sPAP), measured by Transthoracic Doppler-echocardiography (TTE) in patients with early systemic sclerosis (SSc). METHODS: A cross-sectional analysis of the prospective EULAR Scleroderma Trial and Research (EUSTAR) database was performed. SSc patients with <3 years from the first non-Raynaud's phenomenon (RP) symptom at baseline EUSTAR visit, were selected. Elevated sPAP was defined as sPAP>40 mmHg on baseline TTE. First visit SSc related variables, including disease subsets, antibodies and visceral involvement, were examined. RESULTS: From 1,188 patients, 81% were women. Mean (SD) age at first non-RP symptom was 50 (14) years, 55% had limited cutaneous SSc (lcSSc) and 42% active disease. Elevated sPAP was found in 17% of patients, both lcSSc and diffuse cutaneous SSc (dcSSc). In lcSSc, older age at first non-RP symptom, ACA positivity, joint contractures, restrictive defect and lower DLCO, were independently associated with elevated sPAP. In dcSSc, older age at first non-RP symptom, longer time between RP onset and first non-RP symptom, digital ulcers, cardiac blocks, and proteinuria were associated with elevated sPAP. CONCLUSIONS: The prevalence of elevated sPAP on TTE in early SSc patients is considerable. Association with cardiac, lung and renal involvement suggests that, although some patients might have pulmonary arterial hypertension, others may present pulmonary hypertension secondary to lung or heart involvement. Our findings emphasize the need to consider right heart catheterisation in selected early SSc patients with PH suspicion, to clearly determine the cause of PH.

OBJECTIVE: To evaluate the validity of different spondyloarthritis (SpA) features included in the Berlin diagnostic algorithm and the Assessment of SpondyloArthritis international Society (ASAS) classification criteria in an early SpA cohort. METHODS: This was a longitudinal multicenter study including patients from the ESPeranza program cohort who were suspected to have SpA. Subjects were ≤45 years old, and SpA symptom duration was 3-24 months. Patients with axial SpA symptoms were selected and categorized according to diagnosis (yes/no) of axial SpA. Descriptive analysis was performed, and the sensitivity, specificity, predictive value, and likelihood ratio (LR) of each feature were calculated. RESULTS: Of 775 patients suspected to have SpA, 665 had predominantly axial symptoms and 516 of these patients were diagnosed with axial SpA. The most useful SpA features were sacroiliitis on magnetic resonance imaging (positive LR 6.6) or radiograph (positive LR 31.1) and peripheral arthritis (positive LR 8.9). The features with the lowest diagnostic utility were a family history of SpA (positive LR 1.5) and good response to nonsteroidal antiinflammatory drugs (positive LR 1.6). Inflammatory back pain (IBP; according to ASAS criteria) was described in only 27% of SpA patients, with a positive LR of 2.3. HLA-B27 positivity was present in 245 (48%), and the positive LR was 2.8. CONCLUSION: The diagnostic value of SpA features in patients with early axial SpA seems to be different than in patients with longstanding disease. Chronic back pain is better than IBP as an entry point to the diagnostic algorithm. Sacroiliitis on imaging is very important for early diagnosis, while the use of HLA-B27 status as a key factor is questionable.

OBJECTIVE: To determine mortality and causes of death in a multinational inception cohort of subjects with systemic sclerosis (SSc). METHODS: We quantified mortality as standardized mortality ratio (SMR), years of life lost, and percentage mortality in the first decade of disease. The inception cohort comprised subjects recruited within 4 years of disease onset. For comparison, we used a prevalent cohort, which included all subjects irrespective of disease duration at recruitment. We determined a single primary cause of death (SSc related or non-SSc related) using a standardized case report form, and we evaluated predictors of mortality using multivariable Cox regression. RESULTS: In the inception cohort of 1,070 subjects, there were 140 deaths (13%) over a median follow-up of 3.0 years (interquartile range 1.0-5.1 years), with a pooled SMR of 4.06 (95% confidence interval [95% CI] 3.39-4.85), up to 22.4 years of life lost in women and up to 26.0 years of life lost in men, and mortality in the diffuse disease subtype of 24.2% at 8 years. In the prevalent cohort of 3,218 subjects, the pooled SMR was lower at 3.39 (95% CI 3.06-3.71). In the inception cohort, 62.1% of the primary causes of death were SSc related. Malignancy, sepsis, cerebrovascular disease, and ischemic heart disease were the most common non-SSc-related causes of death. Predictors of early mortality included male sex, older age at disease onset, diffuse disease subtype, pulmonary arterial hypertension, and renal crisis. CONCLUSION: Early mortality in SSc is substantial, and prevalent cohorts underestimate mortality in SSc by failing to capture early deaths, particularly in men and those with diffuse disease.

OBJECTIVE: To validate the 2013 ACR/EULAR classification criteria for systemic sclerosis (SSc) in patients from a capillaroscopy clinic. METHODS: All patients attended in a capillaroscopy clinic were included. Sociodemographic and SSc-related variables were collected. Using as gold standard for SSc the clinical judgement, the performance (sensitivity, specificity, predictive values, and likelihood ratios) of the 2013 ACR/EULAR criteria were analyzed. Receiver operating characteristic (ROC) curve and the area under the curve (AUC) were calculated for the global score and individual items, and the best cutoffs were obtained. RESULTS: We included 327 patients (84% women, mean age at capillaroscopy 48 years). Main reasons for capillaroscopy referral were Raynaud's phenomenon (39%) and SSc evaluation (27%). The most frequent final clinical diagnosis were SSc (32.4%) and primary Raynaud's phenomenon (25.7%). The 2013 ACR/EULAR SSc classification criteria were met by 116 patients (35.5%). Sensitivity and specificity of the new criteria were 98.1% and 94.6%, respectively, and positive and negative predictive values were 89.7% and 99.1%. The individual variables with the best sensitivity were Raynaud's phenomenon (99.1%) and abnormal nailfold capillaries (81.1%). All the individual variables, except Raynaud's phenomenon, puffy fingers and sclerodactily showed high specificity values, over 90%. The best cutoffs of the total score were ≥8, ≥9, and ≥10, and the AUC = 0.993. CONCLUSIONS: We validated the new ACR/EULAR classification criteria for SSc in unselected patients from a capillaroscopy clinic. Global score and individual items included in the new criteria show high diagnostic accuracy and discriminatory capacity.

OBJECTIVE: To analyze the causes of death, survival, and risk factors for mortality in a large series of Spanish systemic sclerosis (SSc) patients followed over the last 25 years in a tertiary care university hospital. METHODS: Demographic, clinical, and outcome data from all SSc patients followed in the rheumatology department were included in a database created in 1989. ANOVA, Kruskal-Wallis, or chi(2) tests were used to identify differences among groups; Kaplan-Meier analysis was used to estimate survival, and Cox proportional hazards regression analysis was used to identify factors associated with mortality. RESULTS: A total of 204 patients were included, of whom 182 (89%) were women. Mean age at diagnosis was 49 +/- 17 years, and mean follow-up was 8 years. Over 1635 patient-years, 36 of 44 deaths were attributable to SSc: 28 related to cardiorespiratory involvement, 4 to peripheral vascular disease, 3 to gastrointestinal, and 1 to renal involvement. The main SSc-unrelated causes of death were malignancy (3 cases) and infections (2 cases). Survival rates from disease onset were 85, 75, and 55% at 5, 10, and 20 years, respectively, with poorer survival in patients with renal disease and pulmonary hypertension (PH). Independent prognostic factors for mortality were older age at diagnosis, diffuse skin involvement, proteinuria, PH, and elevated erythrocyte sedimentation rate. CONCLUSIONS: Ten-year survival is over 70% in Spanish SSc patients. The main causes of death are lung and cardiac involvement, and to a lesser extent, peripheral vascular disease and coexisting malignancy. Diffuse subset, proteinuria, PH, elevated erythrocyte sedimentation rate and older age at diagnosis are the main risk factors for mortality.
