Objectives: To assess the associations and prognostic value of scleroderma patterns by nailfold videocapillaroscopy (NVC) in patients with systemic sclerosis (SSc) and cutaneous subsets., Methods: At baseline, 1356 SSc patients from the RESCLE registry were compared according to the scleroderma pattern as Late pattern and non-Late pattern, which included Early and Active patterns. Patient characteristics, disease features, survival time and causes of death were analysed., Results: Late pattern was identified in 540 (39.8%), and non-Late pattern in 816 (60.2%) patients (88% women; 987 lcSSc/251 dcSSc). Late pattern was associated to dcSSc (OR=1.96; p<0.001), interstitial lung disease (ILD) (OR=1.29; p=0.031), and scleroderma renal crisis (OR=3.46; p<0.001). Once the cutaneous subset was disregarded in an alternative analysis, both digital ulcers (DU) (OR=1.29; p<0.037) and anti-topoisomerase I antibodies (OR=1.39; p< 0.036) emerged associated with the Late pattern. By cutaneous subsets, associations with Late pattern were: (1) in dcSSc, acro-osteolysis (OR=2.13; p=0.022), and systolic pulmonary artery pressure >40 mmHg by Doppler echocardiogram (OR=2.24; p<0.001); and (2) in lcSSc, ILD (OR=1.38; p=0.028). Survival was reduced in dcSSc with Late pattern compared to non-Late pattern (p=0.049). Risk factors for SSc mortality in multivariate regression Cox analysis were age at diagnosis (HR=1.03; p<0.001), dcSSc (HR=2.48; p<0.001), DU (HR=1.38; p=0.046), ILD (HR=2.81; p<0.001), and pulmonary arterial hypertension (HR=1.99; p<0.001)., Conclusions: SSc patients with Late pattern more frequently present dcSSc and develop more fibrotic and vascular manifestations. Advanced microangiopathy by NVC identifies dcSSc patients at risk of reduced survival due to SSc-related causes.

Aim: Patients with systemic sclerosis (SSc) are at increased risk of cancer, a growing cause of non-SSc-related death among these patients. We analyzed the increased cancer risk among Spanish patients with SSc using standardized incidence ratios (SIRs) and identified independent cancer risk factors in this population., Material and Methods: Spanish Scleroderma Registry data were analyzed to determine the demographic characteristics of patients with SSc, and logistic regression was used to identify cancer risk factors. SIRs with 95% confidence intervals (CIs) relative to the general Spanish population were calculated., Results: Of 1930 patients with SSc, 206 had cancer, most commonly breast, lung, hematological, and colorectal cancers. Patients with SSc had increased risks of overall cancer (SIR 1.48, 95% CI 1.36-1.60; P < 0.001), and of lung (SIR 2.22, 95% CI 1.77-2.73; P < 0.001), breast (SIR 1.31, 95% CI 1.10-1.54; P = 0.003), and hematological (SIR 2.03, 95% CI 1.52-2.62; P < 0.001) cancers. Cancer was associated with older age at SSc onset (odds ratio [OR] 1.22, 95% CI 1.01-1.03; P < 0.001), the presence of primary biliary cholangitis (OR 2.35, 95% CI 1.18-4.68; P = 0.015) and forced vital capacity <70% (OR 1.8, 95% CI 1.24-2.70; P = 0.002). The presence of anticentromere antibodies lowered the risk of cancer (OR 0.66, 95% CI 0.45-0.97; P = 0.036)., Conclusions: Spanish patients with SSc had an increased cancer risk compared with the general population. Some characteristics, including specific autoantibodies, may be related to this increased risk., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest, including any financial, personal, or other relationship within 3 years of beginning this research with a person or organization that could have inappropriately influenced, or be perceived to influence, this work., (Copyright © 2022 The Authors.

Objectives: Left ventricular diastolic dysfunction (LVDD) remains poorly studied in Systemic Sclerosis (SSc). To determine the prevalence and to define factors associated with LVDD and survival in a large cohort of patients with SSc., Methods: An observational study was conducted with data from the multicentre Spanish Scleroderma Registry (RESCLE) to identify factors associated with LVDD and estimate survival., Results: Out of 1517 patients, 319 (21.0%) had LVDD. The subset of sine scleroderma SSc was associated to LVDD (14.7% vs. 10.6%, p =0.048), whilst diffuse cutaneous SSc was more prevalent in non-LVDD (16.0 % vs. 21.2%, p =0.041). Multivariable analysis identified that LVDD was associated with older age at diagnosis of SSc (OR 1.05; 95% CI 1.04 to 1.06), longer time from diagnosis (OR 1.04; 95% CI 1.03 to 1.06), presence of telangiectasia (OR 1.42; 95% CI 1.08 to 1.88), treatment with calcium channel blockers (CCB) (OR 1.51; 95% CI 1.16 to 1.96), and inversely related to angiotensin-converting-enzyme inhibitors (ACEi) use (OR 0.59; 95% CI 0.44 to 0.80). SSc patients with LVDD had increased mortality (23.8 vs. 17.4%, p =0.010) and shortened survival from the first SSc symptom (p =0.040), even though it was not found to be an independent risk factor for death., Conclusions: LVDD is relatively common in SSc patients, and it is associated with worst prognosis, older age, longer time from diagnosis of SSc, presence of telangiectasia and vasodilator treatment., (Copyright © 2022.

To assess severity markers and outcomes of patients with systemic sclerosis (SSc) with or without pulmonary arterial hypertension (PAH-SSc/non-PAH-SSc), and the impact of interstitial lung disease (ILD) on PAH-SSc. Non-PAH-SSc patients from the Spanish SSc registry and PAH-SSc patients from the Spanish PAH registry were included. A total of 364 PAH-SSc and 1589 non-PAH-SSc patients were included. PAH-SSc patients had worse NYHA-functional class (NYHA-FC), worse forced vital capacity (FVC) (81.2 ± 20.6% vs 93.6 ± 20.6%, P < 0.001), worse tricuspid annular plane systolic excursion (TAPSE) (17.4 ± 5.2 mm vs 19.9 ± 6.7 mm, P < 0.001), higher incidence of pericardial effusion (30% vs 5.2%, P < 0.001) and similar prevalence of ILD (41.8% vs. 44.9%). In individuals with PAH-SSc, ILD was associated with worse hemodynamics and pulmonary function tests (PFT). Up-front combination therapy was used in 59.8% and 61.7% of patients with and without ILD, respectively. Five-year transplant-free survival rate was 41.1% in PAH-SSc patients and 93.9% in non-PAH-SSc patients (P < 0.001). Global survival of PAH-SSc patients was not affected by ILD regardless its severity. The multivariate survival analysis in PAH-SSc patients confirmed age at diagnosis, worse NYHA-FC, increased PVR, reduced DLCO, and lower management with up-front combination therapy as major risk factors. In conclusion, in PAH-SSc cohort risk of death was greatly increased by clinical, PFT, and hemodynamic factors, whereas it was decreased by up-front combination therapy. Concomitant ILD worsened hemodynamics and PFT in PAH-SSc but not survival regardless of FVC impairment., (© 2022. The Author(s).)

Objectives: To assess the clinical profile of patients with anti-polymyositis/Scl (PM/Scl) antibodies in a cohort of Spanish patients with systemic sclerosis., Methods: From the Spanish Scleroderma Study Group database, we selected patients in whom PM/Scl antibodies had been tested. We compared demographic, clinical, laboratory, and survival data between patients with and without PM/Scl antibodies., Results: Seventy-two of 947 patients (7.6%) tested positive for PM/Scl antibodies. Patients with PM/Scl antibodies presented initially with more puffy fingers and arthralgias but less Raynaud phenomenon. Regarding cumulative manifestations, myositis and arthritis were more prevalent in patients with PM/Scl antibodies, as well as pulmonary fibrosis. On the contrary, patients with PM/Scl antibodies had less pulmonary hypertension. No difference in terms of survival at 5 and 10 years was noticed between the 2 groups., Conclusions: In systemic sclerosis patients from Spain, PM/Scl antibodies are associated with a distinct clinical profile. However, PM/Scl antibodies did not influence survival., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)

Introduction: Endothelin antagonist receptors (ERAs) and phosphodiesterase-5 inhibitors (PDE5i) are beneficial in pulmonary arterial hypertension (PAH) and digital ulcers (DU) and prevent from DU recurrences. Our study aimed to determine the difference in the incidence rate of PAH and scleroderma renal crisis (SRC) in patients with SSc and DU (SSc-DU) under ERAs/PDE5i or without treatment., Methods: We conducted a retrospective cohort study including SSc-DU patients from the Spanish Scleroderma Registry (RESCLE). The primary outcome was the incidence rate of PAH and SRC in patients under ERAs/PDE5i or not., Results: Some 544 patients out of 1817 (29.9%) in the RESCLE database had DU, 221 (40.6%) under ERAs/PDE5i and 323 (59.4%) not. The incidence rate (95% CI) difference between patients under treatment or not under did not reach statistical significance in PAH [-0.1 (-4.8, 4.69), P = 0.988] or in SRC [0.7 (-2.2, 3.7), P = 0.620]. However, the time from the first DU to the diagnosis of SRC was delayed in treated patients [mean (s.d.) 7.6 (5.8) years vs 2.9  (5.3); P = 0.021]. The dcSSc subset was more prevalent in the treatment group (36 vs 26%; P = 0.018), along with anti-topoisomerase I antibodies (34 vs 18%; P < 0.001) and tendon friction rubs (12 vs 6%; P = 0.038), whereas the lcSSc subset was more prevalent in the no-treatment group (57 vs 66%; P = 0.031) along with ACA (37 vs 46%; P = 0.031)., Conclusion: There was no difference in the incidence rate of PAH and SRC between groups. However, treatment with ERAs and/or PDE5i appeared to delay the occurrence of SRC., (© The Author(s) 2020. Published by Oxford University Press on behalf of the British Society for Rheumatology.

A few scores predicting the short-term risk of mortality in Systemic sclerosis (SSc) have been reported to date. Our study aimed to create a predictive 15-year all-cause mortality score at the time of the diagnosis of SSc. The study was based on the Spanish Scleroderma Registry (RESCLE). The cohort was split up in derivation (DC) and validation cohort (VC). A multivariate analysis to detect variables related to all-cause mortality within the first 15 years from SSc diagnosis was performed, assigning points to the rounded beta values to create the score (RESCLESCORE). 1935 SSc patients were included. The variables in the final model were as follows: age at diagnosis (+2 points > 65 years-old), male gender (+1 point), lcSSc subset (-1 point), mode of onset other than Raynaud's (+1 point), cancer (+1 point) and visceral involvement, such as ILD (+1 point), PAH (+1 point), heart (+1 point) and renal involvement (+2 points). Autoantibodies did not achieve statistical significance in the multivariate analysis. The 3 categories of risk to predict 15-year all-cause mortality at the time of diagnosis were as follows: low risk (5% vs. 7%, p = .189), intermediate risk (26.5% vs. 25.5%, p = .911) and high risk (47.8% vs. 59%, p = .316). The AUC was 0.799 (DC) vs. 0.778 (VC) (p = .530). In conclusion, the RESCLESCORE demonstrated an excellent ability to categorize SSc patients at the time of diagnosis in separate 15-year all-cause mortality risk strata at the time of diagnosis., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest.

Objectives: Diffuse cutaneous systemic sclerosis (dcSSc) is associated with anti-topoisomerase (ATA) whereas limited cutaneous (lcSSc) and sine scleroderma (ssSSc) are mainly associated with anti-centromere antibody (ACA). Serodiscordant patients were defined as lcSSc subjects with ATA, dcSSc with ACA, and ssSSc with ATA. The aim of the present study was to compare the clinical manifestations and prognosis between serodiscordant patients and their counterparts (those with lcSSc with ACA, dcSSc with ATA and ssSSc with ACA, respectively)., Methods: From the Spanish Scleroderma Registry we selected those patients for whom skin involvement (dcSSc, lcSSc or ssSSc) was detailed at baseline and last visit and ACA and ATA had been determined. Demographic, clinical characteristics, and survival data were compared according to the antibody status., Results: The whole cohort comprised 901 patients and six mutually exclusive groups were defined: lcSScACA in 511 (57%) patients, lcSScATA group in 87 (10%), dcSScATA group in 172 (19%), dcSScACA group in 21 (2%), ssSScACA group in 92 (10%), and ssSScATA group in 18 (2%) patients, respectively. Interstitial lung disease (ILD) and severe ILD were more frequent in patients with dcSScATA than in those with dcSScACA. Conversely, the prevalence of isolated pulmonary hypertension (without ILD) was higher in those with dcSScACA (15% vs. 2%; p=0.018). No differences were found regarding survival when comparing serodiscordant patients with the seroconcordants patients., Conclusions: In our cohort, the prevalence of serodiscordant SSc patients was low. They differed from their counterparts in some clinical manifestations. The management of patients with SSc should be guided by both serology and cutaneous subtype.

Objective: Monotherapy is an option as first-line therapy for pulmonary arterial hypertension (PAH). However, combination therapy is a beneficial alternative. Our objective was to evaluate the efficacy of monotherapy versus combination therapy in patients with systemic sclerosis (SSc)-associated PAH., Methods: All patients with SSc-associated PAH from the Spanish Scleroderma Registry (RESCLE) were reviewed. Patients were split into 3 groups: monotherapy versus sequential combination versus upfront combination therapy. The primary endpoint was death from any cause at 1, 3, and 5 years from PAH diagnosis., Results: Seventy-six patients (4.2%) out of 1817 had SSc-related PAH. Thirty-four patients (45%) were receiving monotherapy [endothelin receptor antagonist (n = 22; 29%) or phosphodiesterase-5 inhibitors (n = 12; 16%)], 25 (33%) sequential combination, and 17 (22%) upfront combination therapy. A lower forced vital capacity/DLCO in the sequential combination group was reported (2.9 ± 1.1 vs 1.8 ± 0.4 vs 2.3 ± 0.8; p = 0.085) and also a higher mean pulmonary arterial pressure in combination groups (37.2 ± 8.7 mmHg vs 40.8 ± 8.8 vs 46 ± 15.9; p = 0.026) at baseline. Treatment regimen (p = 0.017) and functional class (p = 0.007) were found to be independent predictors of mortality. Sequential combination therapy was found to be an independent protective factor (HR 0.11, 95% CI 0.03-0.51; p = 0.004), while upfront combination therapy showed a trend (HR 0.68, 95% CI 0.23-1.97; p = 0.476). Survival from PAH diagnosis among monotherapy, sequential, and upfront combination groups was 78% versus 95.8% versus 94.1% at 1 year, 40.7% versus 81.5% versus 51.8% at 3 years, and 31.6% versus 56.5% versus 34.5% at 5 years (p = 0.007), respectively. Side effects were not significantly different among groups., Conclusion: Combination sequential therapy improved survival in our cohort.

Objectives: To evaluate the clinical features and survival of patients with positive anti-RNA polymerase III (anti-RNAP III) in a Spanish single centre., Methods: We analysed 221 patients with SSc according to LeRoy and Medsger criteria. Twenty-six patients with positivity for anti-RNAP III antibodies were compared with 195 negative patients. Epidemiological, clinical, immunological features and survival were analysed., Results: In patients with anti-RNAP III positivity diffuse cutaneous SSc (dcSSc) subset was the most prevalent (20, 76.9% vs. 35, 17.9%, p < 0.001), with shorter diagnosis delay (4.11 ± 7.34 years vs. 6.77 ± 9.22 years, p = 0.005). Patients with anti-RNAP III antibodies had higher frequency of arterial hypertension (13, 50% vs. 55, 28.2%, p = 0.024), scleroderma renal crisis (SRC) (3, 11.5% vs. 3, 1.5%, p = 0.023), arthritis (9, 34.6% vs. 35, 17.9%, p = 0.046), tendon friction rubs (4, 15.4% vs. 1, 0.5%, p = 0.001) and contractures (5, 19.2% vs. 10, 5.1%, p = 0.02). There were no differences found in the presence of cancer or in global survival. In the multivariate survival analysis, severe interstitial lung disease (ILD) (HR: 8.61, 95%CI 3.40 - 21.81), pulmonary arterial hypertension (PAH) (HR: 4.05, 95%CI 1.42 - 11.61) and SRC (HR: 17.27, 95%CI 3.36 - 88.97) were the only factors associated with poor prognosis., Conclusions: In this cohort anti-RNAP III antibodies are related with dcSSc subset, shorter diagnostic delay and higher prevalence of musculoskeletal involvement, arterial hypertension and SRC. ILD, PAH and SRC were independent prognostic factors.

Introduction: Our objective was to evaluate the pulmonary hypertension (PH) data for Spanish patients with systemic sclerosis (SSc), define the PH types and determine the associated factors., Method: Descriptive study of PH-related data from the multicentre RESCLE registry. Estimated systolic pulmonary artery pressure (esPAP), measured via echocardiogram was considered elevated if ≥ 35 mmHg. Left heart disease (LHD) and interstitial lung disease (ILD) were identified. When performed, data from right heart catheterisation (RHC) were collected., Results: esPAP was elevated in 350 of 808 patients (43.3%). One hundred and forty-four patients (17.8%) were considered to have PH (88 via RHC and the rest due to elevated esPAP along with evidence of significant LHD or ILD): PAH 3.7%, secondary to ILD 8.3%, secondary to LHD 2.8% and unclassified 3%. Prevalence of elevated esPAP was greater in diffuse SSc (dSSc) than in limited scleroderma (lSSc) (50.5 vs. 42.2%, p 0.046). In the group with elevated esPAP, a lower prevalence of anti-centromere antibodies (41.9% vs. 52.3%, p 0.006) and a greater prevalence of anti-topoisomerase-1 antibodies (ATA) (25.1% vs. 18.6%, p 0.04) were observed compared to the group with normal esPAP. Patients with elevated esPAP had a lower rate of digital ulcers (50.6% vs. 60.2%, p 0.007) and esophageal involvement (83.6% vs. 88.7%, p 0.07) and higher rate of renal crisis (4.6% vs. 1.8%, p 0.066)., Conclusions: Prevalence of PAH was lower than expected (3.7%). Probability of having elevated esPAP was higher among patients with dSSc and among those with ATA.

Background: To determine whether lung involvement is related to microvascular perturbations, nailfold videocapillaroscopy (NVC) was performed in patients with systemic sclerosis (SSc)., Methods: A cross-sectional study was consecutively accomplished in 152 SSc patients. NVC, a pulmonary function test and echocardiography were undergone within a 3-month period. Finally, 134 patients with at least eight NVC (200× magnification) images were selected for quantitative and qualitative examinations., Results: Patients with interstitial lung disease presented lower median capillary density (4.86/mm vs 5.88/mm, p = 0.005) and higher median of neoangiogenesis (0.56/mm vs 0.31/mm, p = 0.005). A higher quantity of neoangiogenesis capillaries was found in patients with pulmonary arterial hypertension (0.70/mm vs 0.33/mm, p = 0.008). Multivariate linear regression analysis established a correlation between neoangiogenesis and decreased forced vital capacity (FVC) (p < 0.001): for each capillary with neoangiogenesis visualized on average per 1 mm, FVC was 7.3% reduced. In qualitative NVC, a late pattern as defined by Cutolo was also associated with lower FVC (p = 0.018). The number of giant capillaries was associated with reduced diffusion capacity of the lung for carbon monoxide (DLCO) (p = 0.016); for each giant capillary per 1 mm, DLCO was 11.8% diminished., Conclusions: A good correlation was observed between distinctive quantitative and qualitative NVC features with lung functional parameters such as FVC and DLCO. It is suggested that vasculopathy could play a role in SSc lung involvement.

Objective: To assess the prevalence and causes of hepatobiliary involvement (HBI) in systemic sclerosis (SSc), to investigate the clinical characteristics and prognosis of SSc patients with HBI (SSc-HBI) and without HBI (SSc-non-HBI), and to compare both groups according to the cutaneous SSc subsets., Methods: In all, 1572 SSc patients were collected in the RESCLE registry up to January 2015, and all hepatobiliary disturbances were recorded. We investigated the HBI-related characteristics and survival from the entire SSc cohort and according to the following cutaneous subsets: diffuse cutaneous SSc (dcSSc), limited cutaneous SSc (lcSSc), and SSc sine scleroderma (ssSSc)., Results: Out of 1572, 118 (7.5%) patients had HBI. Primary biliary cholangitis (PBC) was largely the main cause (n = 67, 4.3%), followed by autoimmune hepatitis (n = 19, 1.2%), and anti-mitochondrial negative PBC (n = 6, 0.4%). Other causes of HBI were as follows: secondary liver diseases (n = 11, 0.7%), SSc-related HBI (n = 7, 0.4%), nodular regenerative hyperplasia (n = 3, 0.2%), liver cirrhosis (n = 3, 0.2%), and HBI of unknown origin (n = 2, 0.1%). In multivariate analysis, HBI was independently associated to lesser risk of dcSSc (5.1% vs. 24.4%), and higher frequency of calcinosis (26% vs. 18%), left ventricular diastolic dysfunction (46% vs. 27%), sicca syndrome (51% vs. 29%), and anti-centromere antibodies (ACA, 73% vs. 44%). According to the cutaneous subsets, HBI was associated (1) in lcSSc, to longer time from SSc onset to diagnosis (10.8 ± 12.5 vs. 7.2 ± 9.3 years), sicca syndrome (54% vs. 33%), and ACA (80% vs. 56%); (2) in ssSSc, to sicca syndrome (44% vs. 19%), and (3) in dcSSc, no associations were found. HBI was the cause of death in 2.3% patients but the cumulative survival according to the presence or absence of HBI showed no differences., Conclusions: HBI prevalence in SSc is 7.5% and dcSSc is the least involved subset. PBC is the main cause of HBI. Patients with SSc-HBI exhibited specific clinical and immunologic profile. Survival is similar for SSc patients with HBI., (Copyright © 2017 Elsevier Inc.

The objective of the study is to determine the importance of the mode of onset as prognostic factor in systemic sclerosis (SSc). Data were collected from the Spanish Scleroderma Registry (RESCLE), a nationwide retrospective multicenter database created in 2006. As first symptom, we included Raynaud's phenomenon (RP), cutaneous sclerosis, arthralgia/arthritis, puffy hands, interstitial lung disease (ILD), pulmonary arterial hypertension (PAH), and digestive hypomotility. A total of 1625 patients were recruited. One thousand three hundred forty-two patients (83%) presented with RP as first symptom and 283 patients (17%) did not. Survival from first symptom in those patients with RP mode of onset was higher at any time than those with onset as non-Raynaud's phenomenon: 97 vs. 90% at 5 years, 93 vs. 82% at 10 years, 83 vs. 62% at 20 years, and 71 vs. 50% at 30 years (p < 0.001). In multivariate analysis, factors related to mortality were older age at onset, male gender, dcSSc subset, ILD, PAH, scleroderma renal crisis (SRC), heart involvement, and the mode of onset with non-Raynaud's phenomenon, especially in the form of puffy hands or pulmonary involvement. The mode of onset should be considered an independent prognostic factor in systemic sclerosis and, in particular, patients who initially present with non-Raynaud's phenomenon may be considered of poor prognosis.

Objectives: To evaluate the clinical characteristics of patients with interstitial lung disease (ILD) in the setting of a large cohort of systemic sclerosis (SSc) patients, and to analyse the differences according to the SSc subtype (following the modification of classification criteria of the American College of Rheumatology for SSc proposed by LeRoy and Medsger), factors are associated with moderate-to-severe impairment of lung function, as well as mortality and causes of death., Methods: A descriptive study was performed, using the available data from the Spanish Scleroderma Study Group., Results: Twenty-one referral centers participated in the registry. By April 2014, 1374 patients with SSc had been enrolled, and 595 of whom (43%) had ILD: 316 (53%) with limited cutaneous SSc (lcSSc), 240 (40%) with diffuse cutaneous SSc (dcSSc), and 39 (7%) with SSc sine scleroderma (ssSSc). ILD in the lcSSc and the ssSSc subsets tended to develop later, and showed a less impaired forced vital capacity (FVC) and a ground glass pattern on high-resolution computed tomography (HRCT) less frequently, compared with the dcSSc subset. Factors related to an FVC < 70% of predicted in the multivariate analysis were: dcSSc, positivity to anti-topoisomerase I antibodies, a ground glass pattern on HCRT, an active nailfold capillaroscopy pattern, lower DLco, older age at symptoms onset, and longer time between symptoms onset and ILD diagnosis. Finally, SSc-associated mortality and ILD-related mortality were highest in dcSSc patients, whereas that related to pulmonary arterial hypertension was highest in those with lcSSc-associated ILD., Conclusions: Our study indicates that ILD constitutes a remarkable complication of SSc with significant morbidity and mortality, which should be borne in mind in all three subgroups (lcSSc, dcSSc, and ssSSc).

Objectives: The low overall prevalence of systemic sclerosis (SSc) and the low proportion of male patients have resulted in a scarcity of studies assessing sex differences in Ssc patients, and contradictory results have often been show among those studies that have been performed., Methods: A prospective study was conducted with the Spanish RESCLE register to analyse the influence of gender on survival of SSc patients., Results: In total, 1506 SSc patients (1341 women, 165 men) were recruited from 21 centres. Older age at onset (OR 1.02), shorter time from onset to diagnosis (OR 0.96), smoking (OR 2.57), interstitial lung disease (ILD) (OR 1.58), less predisposition to sicca syndrome and to antinuclear antibody positivity (OR 0.29 and 0.43, respectively), and higher compliance with the ACR 1980 criteria (OR 1.79) were independently associated with the male sex. During follow-up, 30.4% of men versus 14.6% of women died (p<0.001). Survival at 10 years from the onset of symptoms was 75.3% for men and 92.9% for women (p<0.001), and the difference remained after selecting only SSc-related deaths (85.6% vs. 96.1%, p<0.001). The mortality predictive factors were diffuse SSc (OR 2.26), ILD (OR 1.82), digital ulcers (OR 1.38), tendon friction rubs (OR 1.74), male sex (OR 1.53), increased age at onset (OR 1.13) and isolated PH (considering only deaths from diagnosis), both in the overall (OR 3.63) and female cohorts (OR 3.97). The same risk factors were observed in the male cohort, except for isolated PH and ILD., Conclusions: The present study confirms the existence of epidemiological, clinical, laboratory and prognostic gender differences in systemic sclerosis patients.

Objectives: According to the existence of subclinical organ involvement pre-scleroderma should be divided into two subsets: very early and early disease. Pre-scleroderma patients included in the Spanish Scleroderma Registry (RESCLE) Cohort were reclassified into subsets. Differences were evaluated and the risk of progression to definite systemic sclerosis was estimated., Methods: The characteristics of very early and early SSc patients were compared. A logistic regression model was used to determine the risk factors of progression., Results: 1632 patients were included, 36 (2.2%) in the very early subset and 111 (6.8%) in the early subset. There were no differences in sex, age at disease onset, duration of Raynaud's phenomenon, antinuclear antibodies or capillaroscopic findings. Three (8.3%) very early SSc patients evolved to definite SSc, 2 (5.6%) of them meeting the ACR/EULAR 2013 criteria, unlike 31 (28%) early SSc patients, 20 (24%) of them meeting the criteria (p=0.034). Digestive involvement was an independent risk factor of progression (OR 17; 95% CI, 6.1-47.2)., Conclusions: The classification of early forms of scleroderma identifies patients with different prognostic risk of progression. The evolution to definite SSc is more frequent in early than in very early SSc patients. Digestive involvement is a risk factor of progression. An active assessment of organ damage in preclinical stages allows a correct classification and risk stratification, with implications for monitoring and treatment., (Copyright © 2017 Elsevier B.V.

Objective: Digital ulcers (DU) are the most common vascular complication of systemic sclerosis (SSc). We compared the characteristics between patients with prior or current DU with those never affected and evaluated whether a history of DU may be a predictor of vascular, organ involvement, and/or death in patients with SSc., Methods: Data from SSc patients with or without prior or current DU were collected by 19 referral centers in an ongoing registry of Spanish SSc patients, named Registro de ESCLErodermia (RESCLE). Demographics, organ involvement, autoimmunity features, nailfold capillary pattern, survival time, and causes of death were analyzed to identify DU related characteristics and survival of the entire series and according to the following cutaneous subsets-diffuse cutaneous SSc (dcSSc), limited cutaneous SSc (lcSSc), and SSc sine scleroderma (ssSSc)., Results: Out of 1326, 552 patients enrolled in the RESCLE registry had prior or current DU, 88% were women, the mean age was 50 ± 16 years, and the mean disease duration from first SSc symptom was 7.6 ± 9.6 years. Many significant differences were observed in the univariate analysis between patients with and without prior/current DU. Multivariate analysis identified that history of prior/current DU in patients with SSc was independently associated to younger age at SSc diagnosis, diffuse cutaneous SSc, peripheral vascular manifestations such Raynaud's phenomenon, telangiectasia, and acro-osteolysis but no other vascular features such as pulmonary arterial hypertension or scleroderma renal crisis. DU was also associated to calcinosis cutis, interstitial lung disease, as well as worse survival. Multivariate analysis performed in the cutaneous subsets showed that prior/current DU were independently associated: (1) in dcSSc, to younger age at SSc diagnosis, presence of telangiectasia and calcinosis and rarely a non-SSc pattern on nailfold capillaroscopy; (2) in lcSSc, to younger age at SSc diagnosis, presence of Raynaud's phenomenon as well as calcinosis cutis, interstitial lung disease, and higher incidence of death from all causes; and (3) in ssSSc, to younger age at first SSc symptom and greater incidence of death from all causes., Conclusions: Digital ulcers develop in patients with SSc younger at diagnosis, mainly in patients with dcSSc and lcSSc, and they are associated to other peripheral vascular manifestations such as Raynaud's phenomenon, telangiectasia, and acro-osteolysis but also to calcinosis, and interstitial lung disease. History of DU in SSc leads to worse survival, also noticeable for lcSSc and ssSSc subsets but not for dcSSc patients., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Background and Objectives: Primary biliary cirrhosis (PBC) is associated to any systemic autoimmune disease (SAD), in particular systemic sclerosis (SSc). To investigate the prevalence of SAD in a cohort of patients with PBC, specifically the prevalence of SSc and its clinical subtypes, and determining the clinical and biological profile of patients with associated PBC and SSc., Methods: Observational study of 62 patients with PBC following a protocol that included an anamnesis and physical examination to detect the presence of SAD as well as a nailfold capillaroscopy and an immunological study with specific SSc autoantibodies. A comparative analysis was conducted between patients with isolated PBC and patients with PBC and an associated SAD., Results: SAD was associated to PBC in 22 patients (35,4%), and SSc was the most frequent illness, identified in 13 cases (21%). Five patients (8%) without previous diagnosis of SAD fulfilled pre-scleroderma criteria, according to LeRoy and Medsger criteria. The presence of anticentromere antibodies (54,5% vs. 5%, P<.001) was the unique immunological determination identified more frequently in patients with PBC-SAD. The SSc suggestive capillary pattern was visualized in 11 patients (20,4%), mainly the slow pattern. No factors associated with greater morbi-mortality were identified in the PBC-SAD group., Conclusions: It does exist a subgroup of patients with PBC and clinical-biological features suggestive of an SAD, which advise a protocolized study to detect early the association to an SAD., (Copyright © 2015 Elsevier España, S.L.U.

Objective: To compare American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria for systemic sclerosis (SSc) with previous American Rheumatology Association (ARA) criteria., Methods: This was a cross-sectional multicenter study comparing sensitivity of both criteria in the cutaneous subsets in the Spanish scleroderma registry (RESCLE) cohort., Results: In 1222 patients with SSc, the most prevalent items were Raynaud phenomenon (95%), skin thickening (91%), and abnormal capillaroscopy (89%). ARA criteria classified as SSc 63.5% of all patients, and 63%, 100%, 11.2%, and 0% in the limited, diffuse, sine, and pre-SSc subsets, respectively. ACR/EULAR criteria classified 87.5% of all patients and 98.5%, 100%, 41.8%, and 15.9% in the same subsets, respectively., Conclusion: ACR/EULAR criteria are more sensitive than ARA criteria, especially in limited, sine, and pre-SSc subsets.

Systemic sclerosis (SSc) is a rare, multisystem disease showing a large individual variability in disease progression and prognosis. In the present study, we assess survival, causes of death, and risk factors of mortality in a large series of Spanish SSc patients. Consecutive SSc patients fulfilling criteria of the classification by LeRoy were recruited in the survey. Kaplan-Meier and Cox proportional-hazards models were used to analyze survival and to identify predictors of mortality. Among 879 consecutive patients, 138 (15.7%) deaths were registered. Seventy-six out of 138 (55%) deceased patients were due to causes attributed to SSc, and pulmonary hypertension (PH) was the leading cause in 23 (16.6%) patients. Survival rates were 96%, 93%, 83%, and 73% at 5, 10, 20, and 30 years after the first symptom, respectively. Survival rates for diffuse cutaneous SSc (dcSSc) and limited cutaneous SSc were 91%, 86%, 64%, and 39%; and 97%, 95%, 85%, and 81% at 5, 10, 20, and 30 years, respectively (log-rank: 67.63, P < 0.0001). The dcSSc subset, male sex, age at disease onset older than 65 years, digital ulcers, interstitial lung disease (ILD), PH, heart involvement, scleroderma renal crisis (SRC), presence of antitopoisomerase I and absence of anticentromere antibodies, and active capillaroscopic pattern showed reduced survival rate. In a multivariate analysis, older age at disease onset, dcSSc, ILD, PH, and SRC were independent risk factors for mortality. In the present study involving a large cohort of SSc patients, a high prevalence of disease-related causes of death was demonstrated. Older age at disease onset, dcSSc, ILD, PH, and SRC were identified as independent prognostic factors.

Objectives: To compare a cohort of patients with systemic sclerosis sine scleroderma (ssSSc) vs. patients with limited cutaneous systemic sclerosis (lcSSc)., Methods: Forty-five patients with ssSSc and 186 patients with lcSSc were investigated. Demographic, clinical and immunologic features and survival were compared., Results: There were no significant differences between ssSSc and lcSSc in gender, age at onset and interval between onset and diagnosis. ssSSc patients fulfilled the ACR criteria for SSc less than lcSSc patients (13%/77%, p<0.0001). There were no significant differences in articular involvement, myopathy, tendon friction rubs and gastrointestinal, pulmonary, cardiac and renal involvements. There was a trend to higher prevalence of pulmonary arterial hypertension (PAH) in ssSSc patients (29%/19%) but not reach significant difference. The prevalence of antinuclear and anticentromere antibodies and slow capilaroscopic pattern was similar. Sicca syndrome (13%/30%; p=0.024), digital ulcers (16%/50%; p<0.0001), calcinosis (11%/26%; p=0.047) and acroosteolysis (0% /10%; p=0.028) were more frequently in lcSSc. Survival at 5, 10, and 15 yr was not different in ssSSc and lcSSc patients (100%/98%, 100%/98%, and 92%/89%, respectively)., Conclusions: ssSSc and lcSSc patients share demographic, clinical and immunologic features. Survival is also similar in both groups. Differences are mainly due to peripheral vascular manifestations. However, despite great similarities, we believe that ssSSc patients should be considered as a different subset in order to avoid misdiagnosis. ssSSc patients should be truly differentiated from early SSc using sensitive and specific studies looking for any asymptomatic organ involvement.

Objective: To investigate the incidence of clinical and immunological characteristics of a large cohort of Spanish patients with scleroderma (SSc) and identifying factors associated with particular organ manifestations assessed by a nationwide cross-sectional analysis., Methods: We classified SSc patients in 4 subsets using a modification of LeRoy and Medsger classification that included: "prescleroderma" (pre-SSc), limited cutaneous SSc (lcSSc), diffuse cutaneous SSc (dcSSc), and SSc sine scleroderma (ssSSc). Fourteen Spanish centers participated in patient recruitment. On January 2008, the database included 916 consecutive Spanish SSc patients, 801 women (87.4%) and 115 men (12.6%), all of whom fulfilled the classification criteria proposed by LeRoy and Medsger. Epidemiological, clinical, and laboratory data were collected according to a standard protocol. Mean age at diagnosis was 51.2 ± 15.1 years and mean age at disease onset was 44.9.0 ± 15.8 years. lcSSc was the most frequent subset (61.8%) followed by dcSSc (26.5%), ssSSc (7.5%), and preSSc (4%) subsets. Gender ratios were as follows: dcSSc subset, 200 women and 43 men (4.7:1); lcSSc subset, 503 women and 63 men (ratio 7.9:1), and ssSSc subset, 62 women and 7 men (ratio 8.9:1). Digital ulcers, interstitial lung disease (ILD), musculoeskeletal and esophageal involvement, and scleroderma renal crisis were more frequent in dcSSc than lcSSc and ssSSc subsets. The incidence of pulmonary arterial hypertension assessed by echocardiography was similar in all subsets but mean estimated systolic pulmonary arterial pressure was higher in ssSSc than in lcSSc subset (47.3 ± 23.9 mm Hg vs 39.6 ± 19.2 mm Hg; P < 0.03). Cardiac involvement was identified more frequently in ssSSc than in dcSSc and lcSSc subsets (49.3% vs 32.5% and 31.1%, respectively; P = 0.015 and P = 0.004 for both comparisons). Acro-osteolysis (8.2% vs 2.4%, P = 0.049), calcinosis (19.8% vs 7.2%, P < 0.05), and sicca syndrome (37.5% vs 14.5%, P < 0.0001) were more frequent in lcSSc than in ssSSc subsets. The frequency of clinical manifestations related to the presence of anticentromere antibodies or antitopoisomerase I antibodies was very similar to that identified in patients categorized to lcSSc and dcSSc, respectively. However, in multivariate studies, the ranking of the variables according to their overall explanatory effect on the model showed that the contributory effect of the antibody status was not greater than that of the clinical categorization into lcSSc and dcSSc for the majority of disease manifestations, but, in important manifestations, as ILD, absence of anticentromere antibodies was an independent predictor factor., Conclusions: The classification of SSc into dcSSc, lcSSc, and ssSSc subsets is the one that most closely reflects the natural history of the disease, as they presented clear clinical differences. The immunological profile helps to define important visceral alteration as ILD. Finally, to improve early diagnosis of SSc, patients with preSSc should be considered both to trace the true evolution of the disease and to define which patients could benefit from therapeutic measures able to prevent the appearance of visceral involvements., (Copyright © 2012 Elsevier Inc.

This study aims to determine the effectiveness of mycophenolate sodium (MS) in patients with scleroderma (SSc)-related interstitial lung disease (ILD). In a prospective observational study, we evaluated 14 consecutive SSc-ILD patients who were treated with MS for 12 months. The effect of MS on lung function was examined by using longitudinal data analytic methods. Wilcoxon rank-sum tests were used to examine the forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and diffusing capacity of the lung for carbon monoxide (DLCO) by pulmonary function testing. As a group, the median values for FVC, FEV1 and DLCO did not change significantly after 12 months of MS therapy and fulfilled the definition of stable disease by the American Thoracic Society. Individually, after 12 months of treatment, 6 out of 14 patients showed a pulmonary improvement defined as an increase of more than 10% in FVC, and 5 out of 14 patients remained stable. By contrast, the median FVC had declined a non-significant 7.2% from the previous 12 months before MS initiation. No significant drug adverse effects were registered. These prospective data suggest that MS is a safe and well-tolerated therapy for SSc-ILD patients, and it is capable of preventing functional pulmonary deterioration.

Raynaud's phenomenon is a frequent reason for seeking of medical attention, since it affects 3-5% of the population. It is characterized by sudden, transient and recurrent episodes of pallor and/or digital cyanosis, after exposure to cold or stressful situations. No known underlying illness is identified in over 80% of cases and consequently these cases are classified as primary Raynaud's phenomenon. Connective tissue diseases, particularly systemic sclerosis, are the main causes of the phenomenon. Once a complete clinical and physical evaluation rule out other causes, a nailfold capillaroscopy and antinuclear antibodies determination are the most useful adjunctive tests. Mild Raynaud's phenomenon can be managed almost exclusively with conservative non-pharmacological lifestyle modifications. However, if a patient develops a severe vascular condition a suitable vasodilator treatment is needed. When critical digital ischemia develops, intravenous treatment with prostaglandin analogues and surgery may be useful.

Objective: Interstitial lung disease (ILD) frequently complicates systemic sclerosis (SSc). Cyclophosphamide (CYC) is a promising immunosuppressive therapy for SSc-related ILD. Our objective was to investigate the effectiveness of an intravenous CYC (iv CYC) pulse regime in SSc-related ILD during treatment and thereafter., Methods: In a prospective observational study ten consecutive patients with SSc-related ILD were treated with iv CYC in a pulse regime lasting from 6 to 24 months. Clinical status, pulmonary functional testing (PFT) and high resolution computed tomography (HRCT) of the chest were evaluated at enrolment and 6, 12 and 24 months thereafter. After treatment withdrawal, patients were followed up every 6 months with PFT and chest HRCT to monitor lung disease., Results: Clinical improvement was apparent in 8 out of 10 patients. The median values of forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and diffusion lung capacity for carbon monoxide (DLCO) as well as ground-glass pattern on HRCT did not change significantly after 6, 12 and 24 months of therapy. The follow-up continued in 8 out of 10 patients after treatment withdrawal for a median of 26.5 months (range: 12-48 months). The final median FVC was 54.5% of predicted value (interquartile range, IQR= 31.6%-94%). Only one patient suffered a FVC deterioration greater than 10%, even though less than 160 ml. The final median DLCO was 68% of predicted value (IQR=38.3-83.6%). Only 2 patients who developed pulmonary arterial hypertension deteriorated their DLCO values of more than 15%., Conclusions: An iv CYC pulse regimen over 24 months may stabilize pulmonary activity in patients with SSc-related ILD during the course of treatment and for a median of 26.5 months thereafter.

Introduction: Our main aim with this study is to establish the epidemiologic and clinical features, treatment response and complications of a group composed of 55 patients with biopsy proven temporal arteritis in a local hospital., Material and Methods: Retrospective study based on clinical records revision of patients diagnosed of giant cell arteritis (GCA) made by temporal artery biopsy between 1989 and 2001., Results: The approximated annual incidence of GCA in our area is 4.1 cases per 100,000 persons over the age of 50. The mean age at diagnostic was 74 years and the 78,2% were women. The most common symptom at diagnostic was headache (81.5%) followed by systemic manifestations (74.1%) and later we found jaw claudication (32,7%), visual impairment (30.2%), isquemic manifestations (17%). Polymyalgia rheumatica was associated to GCA in 49.1% of cases. The temporal artery explorations was abnormal in the 76.9% of patients. The mean initial dose of corticoids was 69 mg prednisone per day, with a half dose reduction time of .5 months. In spite of that, 24,1% of patients relapsed during the first year. The 38% of patients did some complications during the corticosteroid treatment. The ESR was lower 50 mm in 12.7% of patients; it was anaemia in the 37.7% and thrombocytosis in 32,1%. In these last patients we detected a relation between thrombocytosis and specific visual impairment., Conclusions: The incidence of GCA in our area is low. The results of our series aren't different from others publicated before in clinical manifestations, there is a prevalence of female sex and there is a relation between specific visual impairment and the presence of thrombocytosis.

The novel antipsychotic olanzapine has structural and pharmacological properties similar to clozapine. Until recently, no haematological toxicity has been reported with olanzapine use and it was expected to be a safer alternative. The authors report a case of agranulocytosis induced by olanzapine and reviewed the 11 cases reported in the literature.

Glomerulonephritis is a rare complication of Q fever and is usually associated with the chronic form of disease, i.e., infectious endocarditis. We describe a 31-year-old man with a self-limited acute febrile illness due to Coxiella burnetii infection who had acute renal failure secondary to mesangioproliferative glomerulonephritis. Antibodies to phospholipids were detected and suggested the diagnosis of Q fever in this case.

Transverse myelitis is one of the most serious neurological complications occurring in the course of systemic lupus erythematosus. We describe two lupus patients, with transverse myelitis, one of whom had associated optic neuritis. In both, magnetic resonance imaging of the spinal cord showed an abnormal signal. In one case a good response to steroid and immunosuppressive therapy was observed; the other case failed to improve despite the therapy applied.

Cholesterol embolism is a rare but serious complication of heart catheterization. We report a patient in whom cholesterol embolization syndrome developed after coronary angioplasty complicated by an acute myocardial infarction which was treated with streptokinase and heparin. The clinical outcome was satisfactory. Cholesterol embolism occurrence might have been precipitated in this patient by thrombolytic and anticoagulant therapy.

Both Raynaud's phenomenon and the presence of antinuclear antibodies are uncommon features of malignant disease and the association of both with a malignancy extremely rare. The case is reported of a 78 year old woman who presented with Raynaud's phenomenon and positive antinuclear antibodies related to adenocarcinoma of unknown primary site.
