RESUMO
Exceptional pandemic lockdown measures enabled singular experiments such as analysing the energy consumption of vacant buildings. This paper assesses the impact of the COVID-19 lockdown on the energy use of academic buildings. For this purpose, weather-adjusted energy use was compared before and during the lockdown, including different levels of lockdown restrictions. Results obtained for the 83 academic buildings of Universitat Politècnica de Catalunya - Barcelona Tech (UPC) reveal that the avoided energy consumption amounted to over 4.3 GWh during the post-pandemic year. However, the results indicate that academic buildings were still using approximately 46.9% of their typical energy consumption during strict lockdown. This revelation emphasizes the high environmental burden of buildings, regardless of whether they are occupied.
RESUMO
The current COVID-19 pandemic is caused by the SARS-CoV-2 coronavirus. The initial recognized symptoms were respiratory, sometimes culminating in severe respiratory distress requiring ventilation, and causing death in a percentage of those infected. As time has passed, other symptoms have been recognized. The initial reports of cutaneous manifestations were from Italian dermatologists, probably because Italy was the first European country to be heavily affected by the pandemic. The overall clinical presentation, course and outcome of SARS-CoV-2 infection in children differ from those in adults, as do the cutaneous manifestations of childhood. In this review, we summarize the current knowledge on the cutaneous manifestations of COVID-19 in children after thorough and critical review of articles published in the literature and from the personal experience of a large panel of paediatric dermatologists in Europe. In Part 1, we discussed one of the first and most widespread cutaneous manifestations of COVID-19, chilblain-like lesions. In this part of the review, we describe other manifestations, including erythema multiforme, urticaria and Kawasaki disease-like inflammatory multisystemic syndrome. In Part 3, we discuss the histological findings of COVID-19 manifestations, and the testing and management of infected children for both COVID-19 and any other pre-existing conditions.

OBJECTIVE: Major salivary gland ultrasonography (SGUS) is widely used for the diagnosis of primary Sjögren's syndrome (pSS). Our objective was to assess the contribution of SGUS compared to other items of the 2016 ACR/EULAR pSS classification criteria, based on expert opinion. METHODS: A secure web-based relational database was used by 24 experts from 14 countries to assess 512 realistic vignettes developed from data of patients with suspected pSS. Each vignette provided classification criteria items and information on history, clinical symptoms and SGUS findings. Each expert assessed 64 vignettes, and each vignette was assessed by 3 experts. A diagnosis of pSS was defined according to at least 2 of 3 experts. Validation was performed in the independent French DiapSS cohort of patients with suspected pSS. RESULTS: A criteria-based pSS diagnosis and SGUS findings were independently associated with an expert diagnosis of pSS (P < 0.001). The derived diagnostic weights of individual items in the 2016 ACR/EULAR criteria including SGUS were as follows: anti-SSA, 3; focus score ≥ 1, 3; SGUS score ≥ 2, 1; positive Schirmer's test, 1; dry mouth, 1; and salivary flow rate < 0.1 mL/min, 1. The corrected C statistic area under the curve for the new weighted score was 0.96. Adding SGUS improves the sensitivity from 90.2 % to 95.6% with a quite similar specificity 84.1% versus 82.6%. Results were similar in the DiapSS cohort: adding SGUS improves the sensitivity from 87% to 93%. CONCLUSION: SGUS had similar weight compared to minor items, and its addition improves the performance of the 2016 ACR/EULAR classification criteria.

Sjögren syndrome is a systemic autoimmune disease that principally affects women between the fourth and sixth decades of life who present with sicca symptomatology caused by dryness of the main mucosal surfaces. The clinical spectrum of Sjögren syndrome extends from dryness to systemic involvement. Since 1978, Sjögren syndrome has been closely associated with an enhanced risk of lymphoma, one of the most severe complications a patient may develop. Primary Sjögren syndrome patients have a 10-44-fold greater risk of lymphoma than healthy individuals, higher than that reported for systemic lupus erythematosus and rheumatoid arthritis. The close link between lymphoma and Sjögren syndrome is clearly exemplified by the very specific type of lymphoma arising in Sjögren syndrome patients, mainly low-grade B-cell lymphomas (predominantly a marginal zone histological type) with primary extranodal involvement of the major salivary glands (overwhelmingly parotid), with a primordial role of cryoglobulinemic-related markers (both clinical and immunological). The most recent studies support a higher number of risk factors detected in an individual leads to a higher lymphoma risk. A close follow-up of high-risk groups with longitudinal assessments of all known risk factors, including cryoglobulin-related markers and EULAR Sjögren's syndrome disease activity index measurement in particular, is mandatory.

Autoantibodies to dense fine speckles 70 (DFS70) are purported to rule out the diagnosis of SLE when they occur in the absence of other SLE-related autoantibodies. This study is the first to report the prevalence of anti-DFS70 in an early, multinational inception SLE cohort and examine demographic, clinical, and autoantibody associations. Patients were enrolled in the Systemic Lupus International Collaborating Clinics (SLICC) inception cohort within 15 months of diagnosis. The association between anti-DFS70 and multiple parameters in 1137 patients was assessed using univariate and multivariate logistic regression. The frequency of anti-DFS70 was 7.1% (95% CI: 5.7-8.8%), while only 1.1% (95% CI: 0.6-1.9%) were monospecific for anti-DFS70. In multivariate analysis, patients with musculoskeletal activity (Odds Ratio (OR) 1.24 [95% CI: 1.10, 1.41]) or with anti-ß2 glycoprotein 1 (OR 2.17 [95% CI: 1.22, 3.87]) were more likely and patients with anti-dsDNA (OR 0.53 [95% CI: 0.31, 0.92]) or anti-SSB/La (OR 0.25 [95% CI: 0.08, 0.81]) were less likely to have anti-DFS70. In this study, the prevalence of anti-DFS70 was higher than the range previously published for adult SLE (7.1 versus 0-2.8%) and was associated with musculoskeletal activity and anti-ß2 glycoprotein 1 autoantibodies. However, 'monospecific' anti-DFS70 autoantibodies were rare (1.1%) and therefore may be helpful to discriminate between ANA-positive healthy individuals and SLE.

OBJECTIVE: To score systemic activity at diagnosis and correlate baseline activity with survival in a large cohort of patients with primary Sjögren syndrome (SS). PATIENTS AND METHODS: We include 1045 consecutive patients who fulfilled the 2002 classification criteria for primary SS. The clinical and immunological characteristics and level of activity (EULAR-SS Disease Activity Index (ESSDAI) scores) were assessed at diagnosis as predictors of death using Cox proportional hazards regression analysis adjusted for age at diagnosis. The risk of death was calculated at diagnosis according to four different predictive models. RESULTS: After a mean follow-up of 117â months, 115 (11%) patients died. The adjusted standardised mortality ratio for the total cohort was 4.66 (95% CI 3.85 to 5.60), and survival rates at 5, 10, 20 and 30â years were 96%, 90%, 81% and 60%, respectively. The main baseline factors associated with overall mortality in the multivariate analysis were male gender, cryoglobulins and low C4 levels. Baseline activity in the constitutional, pulmonary and biological domains was associated with a higher risk of death. High activity in at least one ESSDAI domain (HR 2.14), a baseline ESSDAI score ≥14 (HR 1.85) and more than one laboratory predictive marker (lymphopenia, anti-La, monoclonal gammopathy, low C3, low C4 and/or cryoglobulins) (HR 2.82) were associated with overall mortality; these HRs increased threefold to 10-fold when the analysis was restricted to mortality associated with systemic disease. CONCLUSIONS: Patients with primary SS, who present at diagnosis with high systemic activity (ESSDAI ≥14) and/or predictive immunological markers (especially those with more than one), are at higher risk of death.

Autoimmune congenital heart block (ACHB) is an immune-mediated cardiac disease included among the manifestations collectively referred to as neonatal lupus. The placental transference of maternal Ro/La autoantibodies may damage the conduction tissues during fetal development leading to blocking of signal conduction at the atrioventricular (AV) node in an otherwise structurally normal heart. Irreversible complete AV block is the main cardiac manifestation of ACHB, but some babies may develop endocardial fibroelastosis, valvular insufficiency, and/or frank cardiomyopathies with significantly reduced cardiac function requiring transplant. The severity of ACHB is illustrated by a global mortality rate of 20% and pacemaker rates of at least 64%, often within the first year of life. This review analyses the main complex and/or unusual clinical situations associated with ACHB, including unusual maternal immunological profiles, infrequent maternal autoimmune diseases, cardiac damage unrelated to AV block, fetal invasive management, late complications after birth, risk of congenital heart block (CHB) in ovodonation and in vitro fertilization techniques, the role of maternal features other than autoimmunity, the influence of the birth order or the risk of CHB in twins and triplets.

OBJECTIVE: The objective of this paper is to evaluate the prevalence and characterize the main epidemiological, clinical and immunological features of annular erythema (AE) in non-Asian patients with primary Sjögren's syndrome (SS). METHODS: We carried out a retrospective study searching for AE in 377 Spanish patients with primary SS fulfilling the 2002 American-European criteria. In addition, we searched PubMed (1994-2012) using the MeSH terms "annular erythema" and "primary Sjögren's syndrome" for additional cases. All cases with AE reported in patients with SS associated with systemic lupus erythematosus were excluded. RESULTS: In our Spanish cohort, we found 35 (9%) patients diagnosed with AE. All were white females, with a mean age of 47 years at diagnosis of AE. AE preceded diagnosis of SS in 27 (77%) patients. Cutaneous AE lesions involved principally the face and upper extremities. All patients reported photosensitivity, with cutaneous flares being reported during the warmest months in 93% of patients. Immunological markers consisted of anti-Ro/La antibodies in 31 (89%) patients. In the literature search, we identified eight additional non-Asian patients with primary SS diagnosed with AE. In comparison with 52 Asian patients, the 43 non-Asian patients with AE related to primary SS were more frequently women (100% vs 78%, p=0.008), and cutaneous lesions were less frequently reported in the face (55% vs 81%, p=0.045) and more frequently in the neck (40% vs 14%, p=0.041). Immunologically, non-Asian patients had a lower frequency of anti-Ro antibodies and a higher frequency of negative Ro/La antibodies, although the differences were not statistically significant. CONCLUSION: AE is not an exclusive cutaneous feature of Asian patients with primary SS. In addition to the characteristic cutaneous expression, AE has a very specific clinical and immunological profile: often presenting before the fulfillment of SS criteria, overwhelmingly associated with anti-Ro antibodies but weakly associated with other immunological markers and the main systemic SS-related features.

OBJECTIVE: To determine the effectiveness of Problem Solving Technique in reducing anxiety and depression, and increased perceived well-being in women family caregivers of chronic patients. DESIGN: A clinical trial FIELD OF STUDY: Health centres in Tarragona, Spain, during 2007-2011. PARTICIPANTS: A sample 122 caregivers of patients in home care programs that met the inclusion criteria, were assigned to intervention or control group according to a simple random process. INTERVENTIONS: In the experimental group, the nurses applied the Problem Solving Technique to the caregiver according to a four-session protocol. The nurses provided the usual care to the caregivers In the control group. One month after intervention, the dependent vriables were measured again in both groups. PRINCIPAL MEASUREMENT: The dependent variables of anxiety and depression were measured using the Goldberg scale, and the emotional well-being variable by the scale of emotional health of the primary caregiver. RESULTS: A statistically significant improvement was detected in the anxiety and depression symptoms, as well as the perceived well-being in the intervention group compared to the control group. CONCLUSIONS: Implementation of the Problem Solving Technique is a useful therapeutic tool for reducing symptoms of distress in family caregivers of chronic patients.

BACKGROUND: To develop preliminary classification criteria for the cryoglobulinaemic syndrome or cryoglobulinaemic vasculitis (CV). METHODS: Study part I developed a questionnaire for CV to be included in the formal, second part (study part II). Positivity of serum cryoglobulins was defined by experts as an essential condition for CV classification. In study part II, a core set of classification items (questionnaire, clinical and laboratory items, as agreed) was tested in three groups of patients and controls-that is, group A (new patients with the CV), group B (controls with serum cryoglobulins but lacking CV) and group C (controls without serum cryoglobulins but with features which can be observed in CV). RESULTS: In study part I (188 cases, 284 controls), a positive response to at least two of three selected questions showed a sensitivity of 81.9% and a specificity of 83.5% for CV. This questionnaire was employed and validated in study part II, which included 272 patients in group A and 228 controls in group B. The final classification criteria for CV, by pooling data from group A and group B, required the positivity of questionnaire plus clinical, questionnaire plus laboratory, or clinical plus laboratory items, or all the three, providing a sensitivity of 88.5% and a specificity of 93.6% for CV. By comparing data in group A versus group C (425 controls), the same classification criteria showed a sensitivity 88.5% and a specificity 97.0% for CV. CONCLUSION: Classification criteria for CV were developed, and now need validation.

OBJECTIVE: To examine change in health-related quality of life in association with clinical outcomes of neuropsychiatric events in systemic lupus erythematosus (SLE). METHODS: An international study evaluated newly diagnosed SLE patients for neuropsychiatric events attributed to SLE and non-SLE causes. The outcome of events was determined by a physician-completed seven-point scale and compared with patient-completed Short Form 36 (SF-36) health survey questionnaires. Statistical analysis used linear mixed-effects regression models with patient-specific random effects. RESULTS: 274 patients (92% female; 68% Caucasian), from a cohort of 1400, had one or more neuropsychiatric event in which the interval between assessments was 12.3 ± 2 months. The overall difference in change between visits in mental component summary (MCS) scores of the SF-36 was significant (p<0.0001) following adjustments for gender, ethnicity, centre and previous score. A consistent improvement in neuropsychiatric status (N=295) was associated with an increase in the mean (SD) adjusted MCS score of 3.66 (0.89) in SF-36 scores. Between paired visits when the neuropsychiatric status consistently deteriorated (N=30), the adjusted MCS score decreased by 4.00 (1.96). For the physical component summary scores the corresponding changes were +1.73 (0.71) and -0.62 (1.58) (p<0.05), respectively. Changes in SF-36 subscales were in the same direction (p<0.05; with the exception of role physical). Sensitivity analyses confirmed these findings. Adjustment for age, education, medications, SLE disease activity, organ damage, disease duration, attribution and characteristics of neuropsychiatric events did not substantially alter the results. CONCLUSION: Changes in SF-36 summary and subscale scores, in particular those related to mental health, are strongly associated with the clinical outcome of neuropsychiatric events in SLE patients.

OBJECTIVE: Neuropsychiatric events occur unpredictably in systemic lupus erythematosus (SLE) and most biomarker associations remain to be prospectively validated. This study examined a disease inception cohort of 1047 SLE patients to determine which autoantibodies at enrolment predicted subsequent neuropsychiatric events. METHODS: Patients with a recent SLE diagnosis were assessed prospectively for up to 10 years for neuropsychiatric events using the American College of Rheumatology case definitions. Decision rules of graded stringency determined whether neuropsychiatric events were attributable to SLE. Associations between the first neuropsychiatric event and baseline autoantibodies (lupus anticoagulant (LA), anticardiolipin, anti-ß(2) glycoprotein-I, anti-ribosomal P and anti-NR2 glutamate receptor) were tested by Cox proportional hazards regression. RESULTS: Disease duration at enrolment was 5.4 ± 4.2 months, follow-up was 3.6 ± 2.6 years. Patients were 89.1% female with mean (±SD) age 35.2 ± 13.7 years. 495/1047 (47.3%) developed one or more neuropsychiatric event (total 917 events). Neuropsychiatric events attributed to SLE were 15.4% (model A) and 28.2% (model B). At enrolment 21.9% of patients had LA, 13.4% anticardiolipin, 15.1% anti-ß(2) glycoprotein-I, 9.2% anti-ribosomal P and 13.7% anti-NR2 antibodies. LA at baseline was associated with subsequent intracranial thrombosis (total n=22) attributed to SLE (model B) (HR 2.54, 95% CI 1.08 to 5.94). Anti-ribosomal P antibody was associated with subsequent psychosis (total n=14) attributed to SLE (model B) (HR 3.92, 95% CI 1.23 to 12.5, p=0.02). Other autoantibodies did not predict neuropsychiatric events. CONCLUSION: In a prospective study of 1047 recently diagnosed SLE patients, LA and anti-ribosomal P antibodies are associated with an increased future risk of intracranial thrombosis and lupus psychosis, respectively.

AIMS: This study evaluated the impact of cinacalcet on arterial stiffness, determined by pulse wave velocity (PWV), in patients with chronic renal disease and secondary hyperparathyroidism (SHPT). PATIENTS AND METHODS: This prospective, observational study included, SHPT patients with chronic renal disease on dialysis undergoing cinacalcet treatment with a follow-up of 12 months. RESULTS: 21 patients, 62% males, with a mean age of 51.3 years (± 18.0) were included. Cinacalcet was given for at least a year with a mean daily dose of 35 mg (range 30-60 mg). Aortic PWV significantly decreased after 12 months of cinacalcet treatment (9.35 ± 1.83 m/sg vs. 8.66 ± 1.86 m/sg; p = 0.030). Additionally, there was a notable reduction trend in the left ventricular mass index (166.6 ± 39.4 g/m² vs. 156.1 ± 31.8 g/m²), although it did not achieve statistical significance (p = 0.063). Alkaline phosphatase and PTH were significantly decreased during the study. However, serum calcium, phosphorus and blood pressure remained stable. CONCLUSION: The results of this study support the possibility that cinacalcet reduces arterial stiffness of SHPT patients with chronic renal disease after 12 months of treatment. Prospective, randomized clinical trials are needed to confirm these preliminary findings.

To analyze the clinical characteristics and outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with sarcoidosis from a large multicenter cohort from Southern Europe and to identify the risk factors associated with a more complicated infection. We searched for patients with sarcoidosis presenting with SARS-CoV-2 infection (defined according to the European Centre for Disease Prevention and Control guidelines) among those included in the SarcoGEAS Registry, a nationwide, multicenter registry of patients fulfilling the American Thoracic Society/European Respiratory Society/World Association of Sarcoidosis and Other Granulomatous Disorders 1999 classification criteria for sarcoidosis. A 2:1 age-sex-matched subset of patients with sarcoidosis without SARS-CoV-2 infection was selected as control population. Forty-five patients with SARS-CoV-2 infection were identified (28 women, mean age 55 years). Thirty-six patients presented a symptomatic SARS-CoV-2 infection and 14 were hospitalized (12 required supplemental oxygen, 2 intensive care unit admission and 1 mechanical ventilation). Four patients died due to progressive respiratory failure. Patients who required hospital admission had an older mean age (64.9 vs. 51.0 years, p = 0.006), a higher frequency of baseline comorbidities including cardiovascular disease (64% vs. 23%, p = 0.016), diabetes mellitus (43% vs. 13%, p = 0.049) and chronic liver/kidney diseases (36% vs. 0%, p = 0.002) and presented more frequently fever (79% vs. 35%, p = 0.011) and dyspnea (50% vs. 3%, p = 0.001) in comparison with patients managed at home. Age- and sex-adjusted multivariate analysis identified the age at diagnosis of SARS-Cov-2 infection as the only independent variable associated with hospitalization (adjusted odds ratio 1.18, 95% conficence interval 1.04-1.35). A baseline moderate/severe pulmonary impairment in function tests was associated with a higher rate of hospitalization but the difference was not statistically significant (50% vs. 23%, p = 0.219). A close monitoring of SARS-CoV-2 infection in elderly patients with sarcoidosis, especially in those with baseline cardiopulmonary diseases and chronic liver or renal failure, is recommended. The low frequency of severe pulmonary involvement in patients with sarcoidosis from Southern Europe may explain the weak prognostic role of baseline lung impairment in our study, in contrast to studies from other geographical areas.

BACKGROUND: Antimalarial drugs (AMs), chloroquine (CQ) and hydroxychloroquine (HCQ), are frequently withdrawn in patients with lupus with either severe or remitting disease. However, additional effects beyond immunomodulation have been recently described. The aim of the present work was to analyse all the published evidence of the beneficial and adverse effects of AM therapy in systemic lupus erythematosus (SLE). METHODS: A systematic review of the English literature between 1982 and 2007 was conducted using the MEDLINE and EMBASE databases. Randomised controlled trials (RCTs) and observational studies were selected. Case reports were excluded except for toxicity reports. The GRADE system was used to analyse the quality of the evidence. RESULTS: A total of 95 articles were included in the systematic review. High levels of evidence were found that AMs prevent lupus flares and increase long-term survival of patients with SLE; moderate evidence of protection against irreversible organ damage, thrombosis and bone mass loss. Toxicity related to AMs is infrequent, mild and usually reversible, with HCQ having a safer profile. In pregnant women, high levels of evidence were found that AMs, particularly HCQ, decrease lupus activity without harming the baby. By contrast, evidence supporting an effect on severe lupus activity, lipid levels and subclinical atherosclerosis was weak. Individual papers suggest effects in preventing the evolution from SLE-like to full-blown SLE, influencing vitamin D levels and protecting patients with lupus against cancer. CONCLUSIONS: Given the broad spectrum of beneficial effects and the safety profile, HCQ should be given to most patients with SLE during the whole course of the disease, irrespective of its severity, and be continued during pregnancy.

OBJECTIVES: To determine the frequency, accrual, attribution and outcome of neuropsychiatric (NP) events and impact on quality of life over 3 years in a large inception cohort of patients with systemic lupus erythematosus (SLE). METHODS: The study was conducted by the Systemic Lupus International Collaborating Clinics. Patients were enrolled within 15 months of SLE diagnosis. NP events were identified using the American College of Rheumatology case definitions, and decision rules were derived to determine the proportion of NP disease attributable to SLE. The outcome of NP events was recorded and patient-perceived impact determined by the SF-36. RESULTS: 1206 patients (89.6% female) with a mean (+/-SD) age of 34.5+/-13.2 years were included in the study. The mean disease duration at enrollment was 5.4+/-4.2 months. Over a mean follow-up of 1.9+/-1.2 years, 486/1206 (40.3%) patients had > or =1 NP events, which were attributed to SLE in 13.0-23.6% of patients using two a priori decision rules. The frequency of individual NP events varied from 47.1% (headache) to 0% (myasthenia gravis). The outcome was significantly better for those NP events attributed to SLE, especially if they occurred within 1.5 years of the diagnosis of SLE. Patients with NP events, regardless of attribution, had significantly lower summary scores for both mental and physical health over the study. CONCLUSIONS: NP events in patients with SLE are of variable frequency, most commonly present early in the disease course and adversely impact patients' quality of life over time. Events attributed to non-SLE causes are more common than those due to SLE, although the latter have a more favourable outcome.

Background Lupus erythematosus (LE) is a chronic, autoimmune disease resulting from an interaction of genetic, environmental and hormonal factors and characterized by a spectrum of clinical forms with variable evolution from a localized cutaneous form to a life-threatening systemic form. Objective To analyse and compare the prevalence and characteristics of the main clinical and immunological manifestations of subacute cutaneous LE (SCLE) and chronic CLE (CCLE). Methods A total of 270 patients with CLE (112 patients with SCLE and 158 patients with CCLE) were studied retrospectively. The clinical and serological characteristics of all the patients were collected in a chart review. Results The patients with SCLE had a higher prevalence of annular and papulosquamous lesions, Raynaud phenomenon, mucous membrane ulcers, malar rashes, photosensitivity, vasculitis and a lower frequency of discoid lesions and alopecia compared with patients with CCLE. Patients with SCLE had a higher prevalence of arthralgias (P < 0.001), xerophthalmia (P = 0.045), arthritis (P < 0.001), nephropathy (P = 0.003) and systemic LE (SLE) (P < 0.001) compared with patients with CCLE. Patients with SCLE also had a higher frequency of laboratory and serological abnormalities than patients with CCLE. Generalized discoid LE (DLE) was associated with a higher prevalence of photosensitivity (P < 0.001), panniculitis (P = 0.009) and SLE (P = 0.003) than localized DLE. In patients with SCLE and those with CCLE, photosensitivity, arthralgias, arthritis, nephropathy and xerophthalmia were associated with SLE. In patients with SCLE, significant correlations existed between clinical and immunological data. Conclusions In our series, differences in the expression of CCLE and SCLE were found with respect to the distribution and type of lesions, systemic features and immunological findings.

We evaluated the prevalence and clinical significance of cardiovascular risk factors in a large series of patients with primary Sjögren's syndrome (SS), focusing on the possible association with clinical and immunological SS features, the therapies administered, and the impact on cardiovascular disease. The study cohort included 312 patients fulfilling the 2002 classification criteria for primary SS, consecutively evaluated and followed in our department between 1984 and 2009. The control group consisted of 312 age- and sex-matched patients without systemic autoimmune diseases followed during the study period in a primary care centre. In comparison with the age- and sex-matched control group, patients with primary SS showed a higher frequency of diabetes mellitus (27% versus 13%, p < 0.001) and hypertriglyceridaemia (22% versus 15%, p = 0.023), and a lower frequency of hypertension (30% versus 46%, p < 0.001) and smoking (19% versus 31%, p < 0.001). The adjusted, multivariate analysis showed that SS patients with at least three cardiovascular risk factors had a higher mean age at SS diagnosis (p < 0.001), a higher frequency of liver involvement (p = 0.01) and central nervous system involvement (p = 0.001), higher mean levels of C-reactive protein (CRP, p = 0.001), a lower percentage of circulating gamma globulins (p = 0.001), and had received corticosteroids more frequently (p = 0.003) in comparison with patients without cardiovascular risk factors. Patients who had received corticosteroids showed a higher frequency of hypertension (37% versus 25%, p = 0.032), diabetes mellitus (37% versus 21%, p = 0.002), and hypertriglyceridaemia (33% versus 15%, p < 0.001). Patients with primary SS showed a twofold higher prevalence of diabetes mellitus and a 1.5-fold higher prevalence of hypertriglyceridaemia in comparison with primary care patients. Corticosteroid use was closely associated with cardiovascular risk factors. These results suggest that cardiovascular risk factors should be taken into account in the management of patients with primary SS and show the importance of recognizing and controlling both traditional and SS-related modifiable risk factors.
