RESUMEN
OBJECTIVE: SSc is a severe, heterogeneous multi-organ disease where population-based estimates on phenotypic spectrum, overall disease burden and societal impact are largely missing. Here the objective was to provide the first-ever complete national-level data on phenotype and major organ afflictions in SSc. METHODS: A stepwise strategy was applied to find and characterize every SSc patient resident in Norway from 2000 to 2012. First we identified every case in the country registered with an International Classification of Diseases, Tenth Revision code for SSc (M34). Next we manually reviewed all cases coded as M34 to determine whether they met the 1980 ACR and/or 2013 ACR/EULAR classification criteria for SSc and could be included in the Norwegian SSc cohort (Nor-SSc). Finally, all disease features from SSc onset to study end were reviewed. RESULTS: The Nor-SSc cohort included 815 SSc patients. The mean age at diagnosis was 53 years, with 84% females and 77% limited cutaneous SSc. The estimated incidence increased from 4 per million in 2000 to 13 per million in 2012. We identified high cumulative frequencies of internal organ involvement, coexistence of multiple organ afflictions across disease subsets and autoantibody status and stable frequencies of pulmonary arterial hypertension across haemodynamic definitions, but indications of referral-related differences in pulmonary hypertension detection rates across the study area. CONCLUSION: This nationwide cohort study provides new, unbiased evidence for a high disease burden in SSc patients of Caucasian descent and indicates the existence of hurdles preventing equality of assessment across the SSc population.

Rationale: Interstitial lung disease (ILD) represents a major challenge in systemic sclerosis (SSc), but there are no precise, population-based data on its overall impact, limiting opportunities for screening and management strategies.Objectives: Evaluate impact of ILD in a unique, nationwide, population-based SSc cohort.Methods: ILD was assessed prospectively in the Norwegian SSc (Nor-SSc) cohort, including all 815 patients with SSc resident in the country from 2000 to 2012. Lung high-resolution computed tomography (HRCT) scans were available for fibrosis quantification at baseline (n = 650, 80%) and follow-up. Pulmonary function tests were assessed at baseline (n = 703, 86%) and follow-up. Vital status and standardized mortality ratios (SMRs) were estimated at study end (2018) in the 630 incident Nor-SSc cases and 15 individually matched control subjects. Cumulative survival rates were computed.Measurements and Main Results: At baseline, 50% of the subjects with SSc (n = 324) had ILD by HRCT and 46% displayed pulmonary function declines consistent with ILD progression. Mortality correlated with extent of lung fibrosis as SMR increased from 2.2 with no fibrosis to 8.0 with greater than 25% fibrosis. SMR was inversely related to baseline FVC% and increased at all FVC levels below 100%. In patients with normal-range baseline FVC (80-100%), the 5- and 10-year survival rates correlated with presence or absence of lung fibrosis, being 83% and 80%, respectively, with no fibrosis and 69% and 56%, respectively, with lung fibrosis (P = 0.03).Conclusions: The mere presence of ILD at baseline appears to affect outcome in SSc, suggesting that all patients with SSc should undergo a baseline pulmonary function test and lung HRCT screening to diagnose ILD early and tailor further management.

OBJECTIVES: Patients with inflammatory joint diseases (IJD) have an increased risk of cardiovascular disease (CVD). Our goal was to examine indications for, and use of, lipid-lowering therapy (LLT) and antihypertensive treatment (AntiHT) in patients with IJD. Furthermore, to investigate the frequency of low-density lipoprotein cholesterol (LDL-c) and blood pressure (BP) goal attainment among IJD patients. METHODS: The cohort was derived from the NOrwegian Collaboration on Atherosclerosis in patients with Rheumatic joint diseases (NOCAR). Indications for AntiHT were: systolic/diastolic BPâ¯≥â¯140/90â¯mmâ¯Hg, self-reported hypertension or AntiHT. CVD risk was estimated by the systematic coronary risk evaluation (SCORE) algorithm. LDL-c goals were <2.6â¯mmol/L in case of diabetes, total cholesterolâ¯>â¯8â¯mmol/L or a SCORE estimateâ¯≥â¯5%, and <1.8â¯mmol/L for those with established CVD or SCOREâ¯≥â¯10%. Comparisons across IJD entities were performed using age and sex adjusted logistic regression. RESULTS: In total, 2277 patients (rheumatoid arthritis: 1376, axial spondyloarthritis: 474, psoriatic arthritis: 427) were included. LLT and AntiHT were indicated in 36.1% and 52.6% of the patients, of whom 37.6% and 47.0% were untreated, respectively. LDL-c and BP targets were obtained in 26.2% and 26.3%, respectively. Guideline recommended treatment and/or corresponding treatment targets were not initiated or obtained in approximately 50%. Rheumatoid arthritis patients were particularly likely to be undertreated with LLT, whereas hypertension undertreatment was most common in psoriatic arthritis. CONCLUSIONS: Inadequate CVD prevention encompasses all the three major IJD entities. The unmet need for CVD preventive measures is not only prevalent in RA, but exists across all the major IJD entities.

OBJECTIVE: The European League Against Rheumatism recommends implementing cardiovascular disease (CVD) risk assessments for patients with inflammatory joint diseases (IJDs) into clinical practice. Our goal was to design a structured programme for CVD risk assessments to be implemented into routine rheumatology outpatient clinic visits. METHODS: The NOrwegian Collaboration on Atherosclerosis in patients with Rheumatic joint diseases (NOCAR) started in April 2014 as a quality assurance project including 11 Norwegian rheumatology clinics. CVD risk factors were recorded by adding lipids to routine laboratory tests, self-reporting of CVD risk factors and blood pressure measurements along with the clinical joint examination. The patients' CVD risks, calculated by the European CVD risk equation SCORE, were evaluated by the rheumatologist. Patients with high or very high CVD risk were referred to their primary care physician for initiation of CVD preventive measures. RESULTS: Data collection (autumn 2015) showed that five of the NOCAR centres had implemented CVD risk assessments. There were 8789 patients eligible for CVD risk evaluation (rheumatoid arthritis (RA), 4483; ankylosing spondylitis (AS), 1663; psoriatic arthritis (PsA), 1928; unspecified and other forms of spondyloarthropathies (SpA), 715) of whom 41.4 % received a CVD risk assessment (RA, 44.7%; AS, 43.4%; PsA, 36.3%; SpA, 30.6%). Considerable differences existed in the proportions of patients receiving CVD risk evaluations across the NOCAR centres. CONCLUSION: Patients with IJD represent a patient group with a high CVD burden that seldom undergoes CVD risk assessments. The NOCAR project lifted the offer of CVD risk evaluation to over 40% in this high-risk patient population.
RESUMEN
OBJECTIVE: The European guidelines on cardiovascular disease (CVD) prevention advise use of relative risk and risk age algorithms for estimating CVD risk in patients with low estimated absolute risk. Patients with inflammatory joint diseases (IJD) are associated with increased risk of CVD. We aimed to estimate relative risk and risk age across IJD entities and evaluate the agreement between 'cardiovascular risk age' and 'vascular age models'. METHODS: Using cross-sectional data from a nationwide project on CVD risk assessment in IJD, risk age estimations were performed in patients with low/moderate absolute risk of fatal CVD. Risk age was calculated according to the cardiovascular risk age and vascular age model, and risk age estimations were compared using regression analysis and calculating percentage of risk age estimations differing ≥5years. RESULTS: Relative risk was increased in 53% and 20% had three times or higher risk compared to individuals with optimal CVD risk factor levels. Furthermore, 20-42% had a risk age ≥5years higher than their actual age, according to the specific risk age model. There were only minor differences between IJD entities regarding relative risk and risk age. Discrepancies ≥5years in estimated risk age were observed in 14-43% of patients. The largest observed difference in calculated risk age was 24years. CONCLUSION: In patients with low estimated absolute risk, estimation of relative CVD risk and risk age may identify additional patients at need of intensive CVD preventive efforts. However, there is a substantial discrepancy between the risk age models.

BACKGROUND: Patients with inflammatory joint diseases (IJD) have increased risk of cardiovascular disease (CVD). Our aim was to compare CVD risk profiles in patients with IJD, including rheumatoid arthritis (RA), axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) and evaluate the future risk of CVD. METHODS: The prevalence and numbers of major CVD risk factors (CVD-RFs) (hypertension, elevated cholesterol, obesity, smoking, and diabetes mellitus) were estimated in patients with RA, axSpA and PsA. Relative and absolute risk of CVD according to Systematic Coronary Risk Evaluation (SCORE) was calculated. RESULTS: In total, 3791 patients were included. CVD was present in 274 patients (7.2%). Of those without established CVD; hypertension and elevated cholesterol were the most frequent CVD-RFs, occurring in 49.8% and 32.8% of patients. Patients with PsA were more often hypertensive and obese. Overall, 73.6% of patients had a minimum of one CVD-RF, which increased from 53.2% among patients aged 30 to <45 years, to 86.2% of patients aged 60 to ≤80 years. Most patients (93.5%) had low/moderate estimated risk of CVD according to SCORE. According to relative risk estimations, 35.2% and 24.7% of patients had two or three times risk or higher, respectively, compared to individuals with no CVD-RFs. CONCLUSIONS: In this nationwide Norwegian project, we have shown for the first time that prevalence and numbers of CVD-RFs were relatively comparable across the three major IJD entities. Furthermore, estimated absolute CVD risk was low, but the relative risk of CVD was markedly high in patients with IJD. Our findings indicate the need for CVD risk assessment in all patients with IJD.
