RESUMO
OBJECTIVES: Tocilizumab (TCZ) is the only biologic therapy approved for giant cell arteritis (GCA). There is general agreement on the initial/maintenance dose, duration of TCZ therapy is not well established. In GiACTA trial, after one year on TCZ, most patients had GCA relapse after withdrawal. The aim of this study is to assess the effectiveness and safety of TCZ therapy optimisation in a large unselected series of patients with GCA in a clinical practice scenario. METHODS: We carried out a multicentre study on 471 GCA patients treated with TCZ. Once prolonged remission was achieved (n=231) and based on a decision between patient and physician, TCZ was optimised (n=125). We compared optimised (TCZOPT) and not optimised (TCZNON-OPT) groups. Prolonged remission defined as normalisation of clinical and laboratory data for 6 months. Optimisation was carried out by decreasing TCZ dose and/or increasing dosing interval. RESULTS: We evaluated 231 GCA patients on TCZ in prolonged remission. At TCZ onset, no differences in demographic, clinical, or laboratory data were observed. First TCZ optimisation was performed after a median follow-up of 12[6-17] months. Intravenous TCZ was optimised from 8 to 4mg/kg/4weeks in 44% patients, while subcutaneous TCZ was optimised from 162mg/w to 162mg/every-other-week in 65% cases. At the end of follow-up, prolonged remission (78.2% vs. 84.2%; p=0.29) and relapses (5.6% vs. 10.4%, p=0.177) were similar in TCZOPT vs. TCZNON-OPT. Severe infections were more frequent in TCZNON-OPT (12.9% vs. 6.6%; p=0.009). CONCLUSIONS: TCZ optimisation may be done once complete remission is achieved by reducing dose or increasing dosing interval. This seems to be effective, safe and cost-effective therapeutic scheme.

OBJECTIVES: A potential point of concern among clinicians is whether results derived from the clinical trials can be reasonably applied or generalised to a definable group of patients seen in real world. It can be the case of the GiACTA study that is a phase III randomised controlled trial of tocilizumab (TCZ) in giant cell arteritis (GCA). To address this question, we compared the clinical features and the responses to TCZ from the GiACTA trial patients with those from a series of GCA seen in the daily clinical practice. METHODS: Comparative study of clinical features between patients from the GiACTA trial (overall n=251) and those from a multicentre series of real-world GCA patients undergoing TCZ therapy (n=134). The diagnosis of GCA in the GiACTA trial was established by the ACR modified criteria whereas in the series of real-world patients it was made by using the ACR criteria, a positive biopsy of temporal artery or the presence of imaging techniques consistent with large-vessel vasculitis in individuals who presented cranial symptoms of GCA. GiACTA trial patients received subcutaneous TCZ (162 mg every 1 or 2 weeks) whereas those from the clinical practice series were treated using standard IV dose (8 mg/kg/month) or subcutaneous (162 mg/week). RESULTS: Real-life patients undergoing TCZ were older with longer disease duration and higher values of ESR and had received conventional immunosuppressive therapy (mainly methotrexate) more commonly than those included in the GiACTA trial. Despite clinical differences, TCZ was equally effective in both GiACTA trial and clinical practice patients. However, serious infections were more commonly observed in GCA patients recruited from the clinical practice. CONCLUSIONS: Despite clinical differences with patients recruited in clinical trials, data from real-life patients confirm the efficacy of TCZ in GCA.

OBJECTIVE: Psoriatic arthritis (PsA) is a chronic inflammatory arthritis affecting up to 30% of patients with psoriasis (Ps). To date, most of the known risk loci for PsA are shared with Ps, and identifying disease-specific variation has proven very challenging. The objective of the present study was to identify genetic variation specific for PsA. METHODS: We performed a genome-wide association study in a cohort of 835 patients with PsA and 1558 controls from Spain. Genetic association was tested at the single marker level and at the pathway level. Meta-analysis was performed with a case-control cohort of 2847 individuals from North America. To confirm the specificity of the genetic associations with PsA, we tested the associated variation using a purely cutaneous psoriasis cohort (PsC, n=614) and a rheumatoid arthritis cohort (RA, n=1191). Using network and drug-repurposing analyses, we further investigated the potential of the PsA-specific associations to guide the development of new drugs in PsA. RESULTS: We identified a new PsA risk single-nucleotide polymorphism at B3GNT2 locus (p=1.10e-08). At the pathway level, we found 14 genetic pathways significantly associated with PsA (pFDR<0.05). From these, the glycosaminoglycan (GAG) metabolism pathway was confirmed to be disease-specific after comparing the PsA cohort with the cohorts of patients with PsC and RA. Finally, we identified candidate drug targets in the GAG metabolism pathway as well as new PsA indications for approved drugs. CONCLUSION: These findings provide insights into the biological mechanisms that are specific for PsA and could contribute to develop more effective therapies.

OBJECTIVES: CPP crystals can be polymorphic (rhomboidal, parallelepiped: R/P), but some look like needles and could be taken as MSU under the bright field microscope. Birefringence of CPP crystals is weaker or absent compared with MSU crystals, but we aim to evaluate whether the grade of birefringence varies regarding the shape of the CPP crystal. METHODS: SF samples from patients with demonstrated acute CPP crystal arthritis were analysed by two observers, using a simple polarized light microscope equipped with two viewing stations. The analysis was performed simultaneously but in a blinded manner. Shape (needles or R/P) and the intensity of birefringence (absent, weak, moderate or MSU-like) were registered. χ2 trend test was used to evaluate the distribution of birefringence regarding the crystal shape. RESULTS: Two-hundred and fifty CPP crystals from 25 SF samples were analysed, well balanced between R/P and needles. The intensity of birefringence significantly differs between R/P or needles in the registries of both observers. R/P most often showed any grade of birefringence compared with needles, while no cases of MSU-like birefringence were found in acicular crystals. Both observers showed high agreement both in crystal shape and in intensity of birefringence. CONCLUSION: CPP crystals birefringence varies according to shape. Needle-shaped CPP crystals did not show strong birefringence, thus reinforcing the value of examining the samples with both ordinary and simple polarized light microscopes in differentiating them from MSU.

The aim of the study is to benchmark the use and attributed importance of well-established prognostic factors in rheumatoid arthritis (RA) in daily clinical practice, and to contrast the use of factors with their ability to predict outcome. Medline was searched (inception-Sep. 2016) for systematic reviews on factors predicting death, disability, structural damage or remission in RA. All factors identified were compiled in a matrix of factors × outcomes, and scoping reviews for each cell were then performed. A survey to 42 rheumatologists randomly selected explored the use of the list of prognostic factors and inquired about the perceived strength of association with poor prognosis. In a second round, participants were exposed to evidence from the matrix and to responses from other participants. Change on perceived strength of association was evaluated. Rheumatologists report using prognostic factors in clinical practice on a daily basis. Very young onset, joint counts at diagnosis, rheumatoid factor, ACPA, and radiographic erosions are used frequently and correctly recognized as strong predictors. Comorbidities and other associated problems, such as obesity, low bone mineral density, cardiovascular disease, or extra-articular manifestations, are perceived as moderately associated to prognosis but, nevertheless, rheumatologists also use them profusely. Genetic and other biomarkers and osteitis by magnetic resonance are less accessible in daily practice and they obtained better results on second round (probably after knowing the strength of association with prognosis). Rheumatologists use widely most prognostic factors with a strong predictive value. However, factors with low evidence of prognostic value are also used and some factors are not used despite good evidence.

OBJECTIVES: Gout-associated cardiovascular (CV) risk relates to comorbidities and crystal-led inflammation. The aim was to estimate the CV risk by prediction tools in new patients with gout and to assess whether ultrasonographic carotid changes are present in patients without high CV risk. METHODS: Cross-sectional study. Consecutive new patients with crystal-proven gout underwent a structured CV consultation, including CV events, risk factors and two risk prediction tools-the Systematic COronary Evaluation (SCORE) and the Framingham Heart Study (FHS). CV risk was stratified according to current European guidelines. Carotid ultrasound (cUS) was performed in patients with less than very high CV risk. The presence of carotid plaques was studied depending on the SCORE and FHS by the area under the curve (AUC) of receiver operating curves. RESULTS: 237 new patients with gout were recruited. CV stratification by scores showed a predominance of very high (95 patients, 40.1%) and moderate (72 patients, 30.5%) risk levels. cUS was performed in 142 patients, finding atheroma plaques in 66 (46.5%, 95% CI 37.8 to 54.2). Following cUS findings, patients classified as very high risk increased from 40.1% up to 67.9% (161/237 patients). SCORE and FHS predicted moderately (AUC 0.711 and 0.683, respectively) the presence of atheroma plaques at cUS. CONCLUSIONS: The majority of patients presenting with gout may be at very high CV risk, indicating the need for initiating optimal prevention strategies at this stage. Risk prediction tools appear to underestimate the presence of carotid plaque in patients with gout.

OBJECTIVES: To evaluate non-adherence to prescribed subcutaneous biologicals in rheumatoid arthritis (RA) patients in Spain. METHODS: ARCO (Study on Adherence of Rheumatoid Arthritis patients to SubCutaneous and Oral Drugs) was a multicentre, non-interventional retrospective study involving 42 rheumatology clinics from representative hospitals throughout Spain. The primary objective was to assess the percentage of patients (aged ≥18 years with an established RA diagnosis) with non-adherence to prescribed subcutaneous biologicals using clinical records and hospital pharmacy dispensing logs as the primary information sources. Adherence was assessed using the Medication Possession Ratio (MPR). Additionally, patients completed the Morisky-Green Medication Adherence Questionnaire. RESULTS: A total of 364 patients (77.5% females, mean age 54.9 years, median RA duration since diagnosis 7.8 years) were enrolled in ARCO. Non-adherence (MPR ≤80%) was reported in 52/363 evaluable patients (14.3%), and was lower in patients receiving initial monthly drug administration (6.4%) than with weekly (17.4%; p=0.034) or every two weeks (14.4%; p=0.102) administration. By multivariate analysis, non-adherence was positively associated with RA duration above the median and with using induction doses. Monthly administration, compared to weekly administration, was inversely associated with non-adherence. Age, gender, order of administration, and changes in the interval of administration, showed no association with non-adherence. Compared with the MPR, the Morisky-Green questionnaire performed poorly in detecting non-adherence. CONCLUSIONS: Non-adherence to the prescribed subcutaneous biological drug occurred in 14.3% of patients with RA. Patients using the most convenient administration period (i.e. monthly) had better adherence than those using more frequent dosing schedules.

The aim of this study was to explore the variability in hospital admissions of patients with spondyloarthritis (SpA) in Spain, and the centre factors that may influence that variability. Descriptive cross-sectional study, part of the emAR II study, performed in Spain (2009-2010). Health records of patients with a diagnosis of SpA and at least one visit to the rheumatology units within the previous 2 years were reviewed. Variables related to hospital admissions, to the SpA, and to the patient and centre were collected. A multilevel logistic regression analysis of random intercept with non-random slopes was performed to assess variability between centres. From 45 centres, 1168 patients' health records were reviewed. Main SpA forms were ankylosing spondylitis (55.2 %) and psoriatic arthritis (22.2 %). A total of 248 admissions were registered for 196 patients (19.2 %, n = 1020). An adjusted variability of 17.6 % in hospitalizations between centres was noted. The following hospital-related factors showed a significant association with admissions: the total number of admissions of the centre, the existence of electronic admission, and the availability of ultrasound in rheumatology. However, these factors only explained 42.9 % of the inter-centre variability. The risk of a patient with SpA of being admitted could double (median OR 2.09), depending on the hospital where the patient was being managed. Hospital admissions of patients with SpA varied between hospitals due to centre characteristics. Further studies are needed to ascertain which specific factors may be causing the variation, as studied variables explained less than half of the variability.

OBJECTIVE: To describe the variability in rheumatology visits and referrals to other medical specialties of patients with spondyloarthritis (SpA) and to explore factors that may influence such variability. METHODS: Nation-wide cross-sectional study performed in 2009-2010. Randomly selected records of patients with a diagnosis of SpA and at least one visit to a rheumatology unit within the previous 2 years were audited. The rates of rheumatology visits and of referrals to other medical specialties were estimated-total and between centres-in the study period. Multilevel regression was used to analyse factors associated with variability and to adjust for clinical and patient characteristics. RESULTS: 1168 patients' records (45 centres) were reviewed, mainly ankylosing spondylitis (55.2 %) and psoriatic arthritis (22.2 %). The patients had incurred in 5908 visits to rheumatology clinics (rate 254 per 100 patient-years), 4307 visits to other medical specialties (19.6 % were referrals from rheumatology), and 775 visits to specialised nurse clinics. An adjusted variability in frequenting rheumatology clinics of 15.7 % between centres was observed. This was partially explained by the number of faculties and trainees. The adjusted intercentre variability for referrals to other specialties was 12.3 %, and it was associated with urban settings, number of procedures, and existence of SpA dedicated clinics; the probability of a patient with SpA of being referred to other specialist may increase up to 25 % depending on the treating centre. CONCLUSION: Frequenting rheumatology clinics and referrals to other specialists significantly varies between centres, after adjustment by patient characteristics.

OBJECTIVE: Copy number variants (CNVs) have been associated with the risk to develop multiple autoimmune diseases. Our objective was to identify CNVs associated with the risk to develop psoriatic arthritis (PsA) using a genome-wide analysis approach. METHODS: A total of 835 patients with PsA and 1498 healthy controls were genotyped for CNVs using the Illumina HumanHap610 BeadChip genotyping platform. Genomic CNVs were characterised using CNstream analysis software and analysed for association using the χ(2) test. The most significant genomic CNV associations with PsA risk were independently tested in a validation sample of 1133 patients with PsA and 1831 healthy controls. In order to test for the specificity of the variants with PsA aetiology, we also analysed the association to a cohort of 822 patients with purely cutaneous psoriasis (PsC). RESULTS: A total of 165 common CNVs were identified in the genome-wide analysis. We found a highly significant association of an intergenic deletion between ADAMTS9 and MAGI1 genes on chromosome 3p14.1 (p=0.00014). Using the independent patient and control cohort, we validated the association between ADAMTS9-MAGI1 deletion and PsA risk (p=0.032). Using next-generation sequencing, we characterised the 26 kb associated deletion. Finally, analysing the PsC cohort we found a lower frequency of the deletion compared with the PsA cohort (p=0.0088) and a similar frequency to that of healthy controls (p>0.3). CONCLUSIONS: The present genome-wide scan for CNVs associated with PsA risk has identified a new deletion associated with disease risk and which is also differential from PsC risk.

OBJECTIVE: The aim of this study was to establish guidelines for the optimization of biologic therapies for health professionals involved in the management of patients with RA, AS and PsA. METHODS: Recommendations were established via consensus by a panel of experts in rheumatology and hospital pharmacy, based on analysis of available scientific evidence obtained from four systematic reviews and on the clinical experience of panellists. The Delphi method was used to evaluate these recommendations, both between panellists and among a wider group of rheumatologists. RESULTS: Previous concepts concerning better management of RA, AS and PsA were reviewed and, more specifically, guidelines for the optimization of biologic therapies used to treat these diseases were formulated. Recommendations were made with the aim of establishing a plan for when and how to taper biologic treatment in patients with these diseases. CONCLUSION: The recommendations established herein aim not only to provide advice on how to improve the risk:benefit ratio and efficiency of such treatments, but also to reduce variability in daily clinical practice in the use of biologic therapies for rheumatic diseases.

OBJECTIVE: to investigate the occurrence and relative risk of incident malignancy in patients with rheumatic diseases and previous malignancies treated with biologic and targeted synthetic DMARDs (b/tsDMARDs). METHODS: Cohort study of patients included in BIOBADASER 3.0 up to 2021, treated with b/tsDMARDs and history of a previous malignancy. Incident cancer was defined as any cancer (new primary, local recurrence or metastases) during the drug exposure. Incidence rate ratios of cancer per 1,000 patients-year (PY) and 95 % confidence interval (CI) were estimated. Rates of incident cancer in tsDMARDs and other bDMARDs versus TNFi were compared. RESULTS: A total of 352 patients from over 9,129 patients recorded in BIOBADASER 3.0 had a history of a previous malignancy. Overall, there were 47 incident malignancies (28 solid cancers, 18 non-melanoma skin cancers and 1 melanoma). The overall rate of incident malignancy was 47.4 (95 % CI 35.6-63.1) events/1,000 PY, ranging between 24.5 events/1000 PY in the anti-CD20 group to 93 events/1000 PY in the anti-CTLA-4 group. We did not find differences in the adjusted rate of incident cancer in patients exposed to JAKi [0.5 (95 % CI 0.2-1.7)], anti-CD20 [0.4(95 % CI 0.1-1)], or anti-IL6 [1.1(95 % CI 0.5-2.4)], anti-CTLA-4 [1.5 (95 % CI 0.7-3.1) or anti-IL17 [0.7 (95 % CI 0.2-2.4) versus TNFi therapy. CONCLUSIONS: We did not find differences in the risk of incident cancer in patients with rheumatic diseases and a previous malignancy between TNFi and other b/tsDMARDs. While incident cancers in our cohort were limited, our data is reassuring, awaiting validation in future studies.

OBJECTIVE: Aortitis in Giant Cell Arteritis (GCA-aortitis) is a frequent complication that may lead to aneurysms. Tocilizumab (TCZ) was approved in GCA, but the efficacy in GCA-aortitis and aneurysms has not been analyzed to date. Our aim was to assess the effectiveness and safety of TCZ in a wide series of GCA-aortitis and aneurysms. METHODS: Multicentre observational study with GCA-aortitis treated with TCZ. GCA was diagnosed by: a) ACR criteria, b) temporal artery biopsy, and/or c) imaging techniques. Aortitis was diagnosed mainly by PET/CT. Main outcomes were EULAR and imaging remission. Others were clinical remission, analytical normalization, corticosteroid-sparing effect, and the prevention and improvement of aneurysms. RESULTS: 196 patients with GCA-aortitis treated with TCZ. After 6 months, 72.2% reached EULAR remission but only 12% an imaging remission; increasing up-to 81.4% and 31.8%, respectively, at 24 months. A rapid clinical remission, ESR and CRP normalization was observed in 47.4%, 84.3% and 55.6%, at 1 month, increasing to 89.6%, 85.3% and 80.3% at 24 months, respectively. Aneurysms were present in 10 (5%) patients. Five of them required early surgery, while 3 others enlarged. No patient on TCZ therapy developed aneurysms during follow-up. CONCLUSION: In patients with GCA-aortitis treated with TCZ, a rapid and maintained clinical and analytical improvement was observed. However, there was an uncoupling between clinical and EULAR remission with imaging remission.
RESUMO
OBJECTIVE: To assess organ damage, with emphasis on the cardiovascular system, over the different stages of the disease in a large SLE cohort. METHODS: Multicentre, longitudinal study of a cohort of 4219 patients with SLE enrolled in the Spanish Society of Rheumatology Lupus Registry. Organ damage was ascertained using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). We longitudinally analysed SDI (globally and for each domain) over time only in the 1274 patients whose dates of damage events had been recorded. RESULTS: During the first year after diagnosis of SLE, 20% of the 1274 patients presented with new damage manifestations. At years 2 and 3, new damage was recorded in 11% and 9% of patients. The annual percentage of patients with new damage after year 5 decreased to 5%. In the first year with the disease, most damage was accumulated in the musculoskeletal, neuropsychiatric and renal systems; in later stages, most damage was in the musculoskeletal, ocular and cardiovascular systems. Considering 'cerebrovascular accident' and 'claudication for 6 months' as cardiovascular items, the cardiovascular system was the second most affected system during the early stages of SLE, with 19% of the patients who presented with damage affected at first year after diagnosis. During the late stages, 20-25% of the patients presenting with new damage did so in this modified cardiovascular domain of the SDI. CONCLUSIONS: New damage occurs mainly during the first year following diagnosis of SLE. Cardiovascular damage is relevant in both the early and the late stages of the disease. Strategies to prevent cardiovascular damage should be implemented early after diagnosis of SLE.
