RESUMO

The role of liver X receptors (LXR) in rheumatoid arthritis (RA) remains controversial. We studied the effect of LXR agonists on fibroblast-like synoviocytes (FLS) from RA patients and the K/BxN arthritis model in LXRα and ß double-deficient (Nr1h2/3-/-) mice. Two synthetic LXR agonists, GW3965 and T0901317, were used to activate LXRs and investigate their effects on cell growth, proliferation and matrix metalloproteinases, and chemokine production in cultured FLS from RA patients. The murine model K/BxN serum transfer of inflammatory arthritis in Nr1h2/3-/- animals was used to investigate the role of LXRs on joint inflammation in vivo. LXR agonists inhibited the FLS proliferative capacity in response to TNF, the chemokine-induced migration, the collagenase activity in FLS supernatant and FLS CXCL12 production. In the K/BxN mouse model, Nr1h2/3-/- animals showed aggravated arthritis, histological inflammation, and joint destruction, as well as an increase in synovial metalloproteases and expression of proinflammatory mediators such as IL-1ß and CCL2 in joints compared with wild type animals. Taken together, these data underscore the importance of LXRs in modulating the joint inflammatory response and highlight them as potential therapeutic targets in RA.

RESUMO

The Spanish Society of Rheumatology (SER) brings together the majority of Spain's rheumatologists and, among the many services it offers its members, has a Research Unit (RU). This unit provides methodological support to SER members in clinical and epidemiological research, coordinates and carries out research projects, designs and maintains large patient databases, develops qualitative research projects and produces evidence-based medicine (EBM) documents. Through this last activity, the RU of the SER produces clinical practice guidelines and recommendation documents on topics relevant to rheumatology that meet the most demanding methodological standards. The aim of this article is to describe the management process and methodology followed by the UI of the SER to identify the topics of its EBM documents and how it executes and develops its guidelines and recommendations.

RESUMO

Background: The early identification of patients' profiles most likely to respond to and maintain long-term therapy with a biological drug can have clinical and cost-effectiveness implications. Objectives: To evaluate the utility of an innovative approach for early identification of patient profiles associated with long-term persistence of golimumab, a tumour necrosis factor inhibitor, in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial spondyloarthritis (SpA) under real-world conditions. Design: Retrospective non-interventional database analysis. Methods: Kaplan-Meier curves of golimumab retention over 8 years from the BIOBADASER registry, overall and by indication, were analysed using a novel approach (a two-phase decay model) to identify the point at which the golimumab retention curve shifted from rapid (indicating high golimumab discontinuation rate) to slow decay (low discontinuation rate). Factors associated with golimumab retention at these time points were identified using Cox regression, and retention rates for different patient profiles were calculated. Results: 885 patients were included. The golimumab retention curve shifted from rapid to slow decay at month 10 for the overall population (retention rate: 73.4%), at month 24 for RA patients (retention: 45.0%), and at month 8 for SpA, including axial SpA and PsA (81.6%). Factors associated with golimumab discontinuation at these early points were, overall, similar to those previously identified at year 8 (RA diagnosis, golimumab as second- or third-line of biological therapy, disease activity over the median and treatment with corticosteroids at golimumab initiation, advanced age [in RA], and female gender [in SpA]). Conclusion: With this novel approach, the factors associated with long-term retention were identified in the initial period of rapid discontinuation of golimumab.

RESUMO

OBJECTIVE: The persistence of biologic (b) and targeted synthetic (ts) disease-modifying antirheumatic drugs(DMARDs) in monotherapy versus in combination with conventional synthetic (cs) DMARDs is still a controversial topic in rheumatic diseases. To clarify this issue, the retention of the initial treatment strategy of b/tsDMARD in combination with csDMARD versus monotherapy in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ankylosing spondylitis (AS) patients under real-life conditions was evaluated. Factors associated with maintenance of the initial strategy were analysed. METHODS: Nested cohort study within the Spanish BIOBADASER III registry. Bivariate comparisons and multivariate Cox proportional hazards models were used for the analyses. RESULTS: A total of 2521 patients were included in the study. In the multivariate model, the initial strategy of combination therapy was associated with shorter persistence in patients with RA (hazard ratio [HR] 1.58;95% confidence interval [CI] 1.00-2.50; p = .049), PsA (HR 2.48; 95% CI 1.65-3.72) and AS (HR 16.77; 95% CI 7.37-38.16; p < .001), regardless of sex, time of disease progression, baseline disease activity, glucocorticoid use or type of b/tsDMARD. Overall, the combination strategy was associated with an increased incidence of adverse events (incidence rate ratio [IRR] 1.13; 95% CI 1.05-1.21). CONCLUSIONS: In this real-life study, the strategy of combining a b/tsDMARD with a csDMARD is associated with lower persistence and worse safety profile compared to monotherapy in RA and especially in PsA and AS, suggesting that combination therapy should be rethought as first choice in RA patients, but especially in PsA and AS patients.

RESUMO

OBJECTIVES: Systemic lupus erythematosus (SLE) patients more commonly have insulin resistance (IR) than control subjects. Recent studies have revealed that the complement (C) system is not only a mediator of the immune system but is also related to the pathogenesis of atherosclerosis in the general population. Given that the C alteration is a characteristic of SLE, in the present work we set out to analyse if there is a relationship between the C system and IR in patients with SLE. METHODS: New generation functional assays of the three pathways of the C system were performed in 225 non-diabetic patients with SLE. In addition, the serum levels of inactive (C1q, C2, C3, C4, factor D), activated (C3a) and regulators (C1 inhibitor and factor H) molecules of the C system were evaluated. Insulin and C-peptide serum levels were measured, and insulin resistance and indices of beta cell function were calculated using the homeostatic model assessment (HOMA). Metabolic syndrome criteria fulfillments were applied. Multivariable linear regression analysis was performed to assess the relationship between C system and IR indices and the presence of metabolic syndrome. RESULTS: After adjusting for covariates that included traditional cardiovascular risk factors associated with IR and prednisone, serum C3a and factor H levels were positively related to higher levels of the HOMA2-IR index. Besides, in the multivariable analysis, after adjustment for covariates, serum levels of C1q and C3 associated with a higher odds ratio for the presence of metabolic syndrome. CONCLUSIONS: IR and metabolic syndrome are positively and independently related to higher serum levels of some serum C elements in patients with SLE with a predominant role of the alternative pathway elements.

RESUMO

OBJECTIVE: Women with psoriatic arthritis (PsA) may have reduced tumor necrosis factor inhibitor (TNFi) effectiveness compared to men. We examined sex differences in treatment response and retention rates during 24 months of follow-up among patients with PsA initiating their first TNFi. METHODS: Data from patients with PsA across 13 European Spondyloarthritis Research Collaboration Network registries starting their first TNFi were pooled. Logistic regression was used to analyze the association between sex and treatment response using low disease activity (LDA) according to the Disease Activity Score in 28 joints using the C-reactive protein level (DAS28-CRP) (<3.2) at six months as the primary outcome. Analyses were adjusted for age, country, conventional synthetic disease-modifying antirheumatic drug treatment, and TNFi start year. Retention rates were explored using the Kaplan-Meier estimator. RESULTS: We analyzed the treatment response of 7,679 patients with PsA (50% women) with available data on LDA at six months. At baseline, women and men had similar characteristics, including mean DAS28-CRP (women vs men, 4.4 [SD 1.2] vs 4.2 [SD 1.2]), though patient-reported outcome measures were worse in women. At six months, 64% of women and 78% of men had LDA (relative risk [RR] 0.82; 95% confidence interval [CI] 0.80-0.84). This difference was similar after adjustment (RR 0.83; 95% CI 0.81-0.85). TNFi retention rates were evaluated in 17,842 patients with PsA. Women had significantly lower retention rates than men at all time points (women 79%, 64%, and 50% vs men 88%, 77%, and 64% at 6, 12, and 24 months, respectively). CONCLUSION: Despite comparable disease characteristics at baseline, women with PsA have reduced treatment response and retention rates to their first TNFi, highlighting the need to consider sex differences in PsA research and management.

RESUMO

OBJECTIVE: To investigate real-world effectiveness of tumor necrosis factor inhibitors (TNFi) in patients with axial spondyloarthritis (axSpA) and the association with 1) treatment line (second and third TNFi-series) and 2) reason for withdrawal from the preceding TNFi (lack of efficacy (LOE) versus adverse events (AE)). METHODS: Prospectively collected routine care data from 12 European registries were pooled. Rates for 12-month drug retention and 6-month remission (Ankylosing Spondylitis Disease Activity Score C-reactive protein inactive disease (ASDAS-ID)) were assessed in second and third TNFi-series and stratified by withdrawal reason. RESULTS: We included 8254 s and 2939 third TNFi-series; 12-month drug retention rates were similar (71%). Six-month ASDAS-ID rates were higher for the second (23%) than third TNFi (16%). Twelve-month drug retention rates for patients withdrawing from the preceding TNFi due to AE versus LOE were similar for the second (68% and 67%) and third TNFi (both 68%), while for the second TNFi, rates were lower in primary than secondary non-responders (LOE < 26 versus ≥26 weeks) (58% versus 71%, p< 0.001). Six-month ASDAS-ID rates for the second TNFi were higher if the withdrawal reason was AE (27%) versus LOE (17%), p< 0.001, while similar for the third TNFi (19% versus 13%, p= 0.20). CONCLUSION: A similar proportion of axSpA patients remained on a second and third TNFi after one year, but with low remission rates for the third TNFi. Remission rates on the second TNFi (but not the third) were higher if the withdrawal reason from the preceding TNFi was AE versus LOE.

RESUMO

Cholesterol efflux capacity (CEC), the ability of high-density lipoprotein (HDL) cholesterol to accept cholesterol from macrophages, has been linked to cardiovascular events. Systemic lupus erythematosus (SLE) is characterized by the consumption of complement (C) proteins and has been associated with an increased risk of cardiovascular disease. CEC is reduced in SLE patients compared to controls. In the present work, our objective was to analyze whether the disruption of C influences CEC in patients with SLE. New-generation functional assays of the three pathways of the C system were performed in 207 patients with SLE. Additionally, serum levels of inactive (C1q, C2, C3, C4, and factor D) and activated (C3a) molecules, and regulators (C1-inhibitor and factor H) of C system were measured. CEC, using an in vitro assay, and lipoprotein serum concentrations were assessed. Multivariable linear regression analysis was performed to assess the relationship between C system and CEC. After full multivariable analysis, the alternative C cascade functional test showed a significant and negative relationship with CEC. This was also the case for C2 and C3, in which the associations were found to be positive and statistically significant, after adjustment for covariates. In conclusion, C system and CEC are interconnected in patients with SLE.

RESUMO

Rheumatoid arthritis (RA) is a chronic inflammatory multisystemic disease of unknown etiology and autoimmune nature that predominantly affects peripheral joints in a symmetrical fashion. Although much progress has been made in understanding the pathophysiology of RA, its etiology remains unknown. Tumor necrosis factor (TNF)-α and interleukin (IL)-6 play the important roles in the pathogenesis and maintenance of inflammation in RA. The presence of anti-citrullinated peptide antibodies aids in the diagnosis in patients with undifferentiated polyarthritis and is associated with a more aggressive RA. The natural history of RA causes joint deformity and disability, as well as reduced life expectancy, both due to increased cardiovascular risk, pulmonary involvement, infections, iatrogenesis or tumors. Early diagnosis and the use of targeted drugs to induce early remission have improved the RA prognosis.

RESUMO

This is the first report comparing EULAR and national treatment recommendations for PsA patients across Europe, and the first this decade to compare ASAS-EULAR and national treatment recommendations in axSpA patients. An electronic survey was completed from October 2021-April 2022 by rheumatologists in 15 European countries. One and four countries followed all EULAR and ASAS-EULAR recommendations, respectively. Five countries had no national treatment recommendations for PsA and/or axSpA, but followed other regulations. In several countries, national treatment recommendations predated the most recent EULAR/ASAS-EULAR recommendations. Entry criteria for starting biologic/targeted synthetic disease-modifying anti-rheumatic drugs varied considerably. In several countries, for PsA patients with significant skin involvement, interleukin-17 inhibitors were not given preference. The positioning of Janus Kinase inhibitors differed and Phosphodiesterase-4 inhibitors were not in use/reimbursed in most countries. This study may motivate European countries to update their national treatment recommendations, to align them better with the latest international recommendations.

RESUMO

BACKGROUND: In patients with rheumatic diseases, the use of biological (b) or targeted synthetic (ts) disease-modifying antirheumatic drugs (DMARDs) after discontinuation of tumor necrosis factor inhibitors (TNFi) is known to be effective. However, data on the use of TNFi after discontinuation of non-TNFi bDMARDs or tsDMARDs (non-TNFi) are scarce. This study assessed the 4-years golimumab retention in patients with rheumatic diseases when used after discontinuation of non-TNFi. METHODS: Adults with rheumatoid arthritis (RA; n = 72), psoriatic arthritis (PsA; n = 30) or axial spondyloarthritis (axSpA; n = 23) who initiated golimumab after discontinuation of non-TNFi from the Spanish registry of biological drugs (BIOBADASER) were analyzed retrospectively. The retention rate (drug survival or persistence) of golimumab up to 4 years was evaluated. RESULTS: The golimumab retention rate was 60.7% (51.4-68.8) at year 1, 45.9% (36.0-55.2) at year 2, 39.9% (29.8-49.7) at year 3 and 33.4% (23.0-44.2) at year 4. Retention rates did not differ significantly whether golimumab was used as second, third, or fourth/subsequent line of therapy (p log-rank = 0.462). Golimumab retention rates were higher in axSpA or PsA patients than in RA patients (p log-rank = 0.002). When golimumab was administered as third or fourth/subsequent line, the 4-years retention rate after discontinuation of non-TNFi was similar to that after discontinuation of TNFi. CONCLUSION: In patients who discontinued non-TNFi, most of whom received golimumab as third/subsequent line of therapy, one-third of patients remained on golimumab at year 4. Retention rates were higher in patients with axSpA and PsA than in those with RA.

RESUMO

Background: To date a complete characterization of the components of the complement (C) pathways (CLassical, LEctin and ALternative) in patients with systemic lupus erythematosus (SLE) has not been performed. We aimed to assess the function of these three C cascades through functional assays and the measurement of individual C proteins. We then studied how they relate to clinical characteristics. Methods: New generation functional assays of the three pathways of the C system were assessed in 284 patients with SLE. Linear regression analysis was performed to study the relationship between the activity, severity, and damage of the disease and C system. Results: Lower values of the functional tests AL and LE were more frequent than those of the CL pathway. Clinical activity was not related to inferior values of C routes functional assays. The presence of increased DNA binding was negatively linked to all three C pathways and products, except for C1-inh and C3a which were positively related. Disease damage revealed a consistent positive, rather than a negative, relationship with pathways and C elements. Anti-ribosomes and anti-nucleosomes were the autoantibodies that showed a greater relationship with C activation, mainly due to the LE and CL pathways. Regarding antiphospholipid antibodies, the most related with C activation were IgG anti-ß2GP, predominantly involving the AL pathway. Conclusion: Not only the CL route, but also the AL and LE are related to SLE features. C expression patterns are linked to disease profiles. While accrual damage was associated with higher functional tests of C pathways, anti-DNA, anti-ribosomes and anti-nucleosomes antibodies, were the ones that showed a higher relationship with C activation, mainly due to the LE and CL pathways.

RESUMO

INTRODUCTION: Tocilizumab (TCZ) treatment is associated with dyslipidaemia, including a rise in triglycerides through a mechanism poorly understood. Three molecules play key roles in the regulation of triglyceride metabolism: apolipoprotein C-III (ApoC-III), angiopoietin-like protein 4(ANGPLT4) and lipoprotein lipase (LPL). The aim of this work was to analyse whether the changes in triglycerides shown by TCZ-treated RA patients could stem from the dysregulation that can occur in these regulatory molecules. METHODS: Twenty-seven RA patients included in the TOCRIVAR study who received TCZ (8 mg/kg IV/q4w) were evaluated at baseline and at Weeks 12, 24 and 52 of treatment. ANGPTL4, ApoC-III and LPL, a complete lipid profile and RA disease activity, were analysed at baseline and at each visit. Multivariable linear mixed models were performed to study changes over time in lipids and regulatory molecules. RESULTS: After 24 weeks of TCZ treatment, HDL cholesterol, apolipoprotein A1 and triglycerides increased, whereas lipoprotein (a) decreased significantly from baseline values. However, 1 year after TCZ, no significant differences in lipid pattern were observed with respect to baseline. Serum ANGPTL4 and Apo-CIII levels decreased gradually over time, both being significantly lower than baseline values at Week 52. LPL concentration did not change significantly during TCZ treatment. Remarkably, the elevation of triglycerides at Week 24 maintained its statistical significance after adjusting for the changes in ApoC-III, ANGPTL4 and LPL. CONCLUSION: In TCZ-treated RA patients basal serum levels of ANGPLT4 and ApoC-III, but not LPL, decreased significantly. However, the elevation of triglycerides after TCZ was not related to changes in these regulatory molecules.

RESUMO

OBJECTIVE: To investigate the influence of COVID-19 vaccination on disease activity in rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients under targeted therapies. PATIENTS AND METHODS: 1765 vaccinated patients COVID-19, 1178 (66.7%) with RA and 587 (33.3%) with PsA from the COVID-19 registry in patients with rheumatic diseases (COVIDSER) project, were included. Demographics, disease characteristics, Disease Activity Score in 28 joints (DAS28) and targeted treatments were collected. DAS28-based flare rates and categorised disease activity distribution prevaccination and post vaccination were analysed by log-linear regression and contingency analyses, respectively. The influence of vaccination on DAS28 variation as a continuous measure was evaluated using a random coefficient model. RESULTS: The distribution of categorised disease activity and flare rates was not significantly modified by vaccination. Log-linear regression showed no significant changes in the rate of flares in the 6-month period after vaccination compared with the same period prior to vaccination in neither patients with RA nor patients with PsA. When DAS28 variations were analysed using random coefficient models, no significant variations in disease activity were detected after vaccination for both groups of patients. However, patients with RA treated with Janus kinase inhibitors (JAK-i) (1) and interleukin-6 inhibitor (IL-6-i) experienced a worsening of disease activity (1.436±0.531, p=0.007, and 1.201±0.550, p=0.029, respectively) in comparison with those treated with tumour necrosis factor inhibitor (TNF-i). Similarly, patients with PsA treated with interleukin-12/23 inhibitor (IL-12/23-i) showed a worsening of disease activity (4.476±1.906, p=0.019) compared with those treated with TNF-i. CONCLUSION: COVID-19 vaccination was not associated with increased rate of flares in patients with RA and PsA. However, a potential increase in disease activity in patients with RA treated with JAK-i and IL-6-i and in patients with PsA treated with IL-12/23-i warrants further investigation.

RESUMO

INTRODUCTION: Glucocorticoids are associated with serious side effects related to dosing and time of use. Unfortunately, there is no standard method for determining glucocorticoid exposure, especially in patients undergoing long-term treatment. OBJECTIVE: The aim of this work was to create a free and easy-to-use web application to calculate, in a systematic way, the total cumulative dose of corticosteroids. METHODS: The total cumulative dose is calculated as the sum of all periods of treatment with different doses of corticosteroids, and is expressed as the equivalent dose of prednisone in mg. Glucocorticoid doses during periods in which the available information is missing or incomplete are estimated by systematic assumptions. RESULTS: A simulation exercise using standard patterns of steroid use in polymyalgia rheumatica, and giant cell arteritis showed that even when the period of no information reached 50% of the time, the accuracy of the calculator had a mean absolute percentage error (MAPE)<7%. CONCLUSION: This tool simplifies and standardizes the glucocorticoids cumulative dose calculation, thereby minimizing bias in the assessment of glucocorticoid cumulative dose.

RESUMO

INTRODUCTION AND OBJECTIVES: Despite the evidence, there are doubts about the positioning of apremilast in the psoriatic arthritis (PsA) treatment algorithm. The objective of this project was to collect the scientific evidence and the experience of a group of rheumatologists who are experts in the management of PsA with apremilast in clinical practice in Spain. MATERIAL AND METHODS: A scientific committee made up of 6 experts proposed 5 clinical scenarios where the evidence on the use of apremilast in PsA was controversial: (i) Efficacy in peripheral PsA; (ii) Efficacy in enthesitis and dactylitis; (iii) Efficacy in PsA with skin involvement; (iv) Comorbidities; and (v) Apremilast safety. After this, a panel of 17 rheumatologists with expertise in PsA management discussed these scenarios and generated a questionnaire with 50 questions and 156 items following the Delphi methodology. This questionnaire was anonymously answered by the panel. RESULTS: After 2 voting rounds, the panel of experts reached consensus in 93 of the 156 items raised (59.6%) (67 in agreement and 26 in disagreement). The degree of consensus was 53.3% in the area of "Efficacy in peripheral PsA"; 60.0% in "Efficacy in enthesitis and dactylitis"; 50.0% in "Efficacy in PsA with skin involvement"; 57.1% in "Management of comorbidities in patients with PsA"; and 67.3% in "Implications of safety in the use of apremilast". CONCLUSIONS: The structured opinion of the experts complements the available evidence and contributes to the establishment of consensual guidelines for the use of apremilast in PsA.

RESUMO

AIM: To assess the golimumab retention rate during up to 8 years of follow up, and any associated factors. METHODS: Retrospective analysis of the BIOBADASER (Spanish registry of biological drugs) database, assessing all adults who had ever started golimumab >6 months before the analysis for an approved indication (rheumatoid arthritis [RA], axial spondyloarthritis [SpA] or psoriatic arthritis [PsA]). RESULTS: Among 885 patients (RA 267, axial SpA 370, PsA 248) receiving 944 cycles of golimumab, the retention rate of golimumab was 71.1% (95% confidence interval: 68.0-73.9) at year 1% and 37.7% (95% CI: 33.3-42.1) at year 7 and at year 8. Retention was higher when golimumab was used as the first biological drug (81.7% at year 1, 49.9% at year 7, p < 0.001). In Cox regression analysis, factors associated with golimumab retention included use as first-line therapy (hazard ratio [HR] for discontinuation 1.52 for second- and 1.79 for third/later-line vs. first-line), use in axial SpA or PsA rather than RA (HR for axial SpA vs. RA 0.59, for PsA vs. Rheumatoid arthritis 0.67), and treatment with concomitant methotrexate (HR 0.67). Factors associated with golimumab discontinuation were corticosteroid use (HR 1.46) and disease activity above median (HR 1.29) at golimumab initiation. CONCLUSION: Based on this retrospective analysis of the BIOBADASER registry, nearly two-fifths (37.7%) of adult rheumatology patients initiating golimumab will remain on treatment for 8 years, with a higher probability of retention in axial SpA or PsA indications and when golimumab is used as first biologic.

RESUMO

Abstract Background In patients with rheumatic diseases, the use of biological (b) or targeted synthetic (ts) disease-modifying antirheumatic drugs (DMARDs) after discontinuation of tumor necrosis factor inhibitors (TNFi) is known to be effective. However, data on the use of TNFi after discontinuation of non-TNFi bDMARDs or tsDMARDs (non-TNFi) are scarce. This study assessed the 4-years golimumab retention in patients with rheumatic diseases when used after discontinuation of non-TNFi. Methods Adults with rheumatoid arthritis (RA; n = 72), psoriatic arthritis (PsA; n = 30) or axial spondyloarthritis (axSpA; n = 23) who initiated golimumab after discontinuation of non-TNFi from the Spanish registry of biological drugs (BIOBADASER) were analyzed retrospectively. The retention rate (drug survival or persistence) of golimumab up to 4 years was evaluated. Results The golimumab retention rate was 60.7% (51.4-68.8) at year 1, 45.9% (36.0-55.2) at year 2, 39.9% (29.8-49.7) at year 3 and 33.4% (23.0-44.2) at year 4. Retention rates did not differ significantly whether golimumab was used as second, third, or fourth/subsequent line of therapy (p log-rank = 0.462). Golimumab retention rates were higher in axSpA or PsA patients than in RA patients (p log-rank = 0.002). When golimumab was administered as third or fourth/subsequent line, the 4-years retention rate after discontinuation of non-TNFi was similar to that after discontinuation of TNFi. Conclusion In patients who discontinued non-TNFi, most of whom received golimumab as third/subsequent line of therapy, one-third of patients remained on golimumab at year 4. Retention rates were higher in patients with axSpA and PsA than in those with RA.

RESUMO

Systemic sclerosis (SSc) is an autoimmune disease that affects skin and multiple internal organs. TGF-ß, a central trigger of cutaneous fibrosis, activates fibroblasts with the involvement of the stress-inducible chaperone heat shock protein 90 isoform α (Hsp90α). Available evidence supports overexpression and secretion of Hsp90α as a feature in profibrotic pathological conditions. The aim of this work is to investigate the expression and function of Hsp90α in experimental models of skin fibrosis such as human fibroblasts, C57BL/6 mice, and in human SSc. For this purpose, we generated a new experimental model based on doxorubicin administration with improved characteristics with respect to the bleomycin model. We visualized disease progression in vivo by fluorescence imaging. In this work, we obtained Hsp90α mRNA overexpression in human skin fibroblasts, in bleomycin- and doxorubicin-induced mouse fibrotic skin, and in lungs of bleomycin- and doxorubicin-treated mice. Hsp90α-deficient mice showed significantly decreased skin thickness compared with wild-type mice in both animal models. In SSc patients, serum Hsp90α levels were increased in patients with lung involvement and in patients with the diffuse form of SSc (dSSc) compared with patients with the limited form of SSc. The serum Hsp90α levels of patients dSSc were correlated with the Rodnan score and the forced vital capacity variable. These results provide new supportive evidence of the contribution of the Hsp90α isoform in the development of skin fibrosis. In SSc, these results indicated that higher serum levels were associated with dSSc and lung fibrosis.

RESUMO

OBJECTIVES: To determine the number of rheumatologists per 100,000 inhabitants working in public or private centres in Spain as a whole, and by Autonomous Community and their distribution by age and sex. MATERIAL AND METHOD: Cross-sectional study based on the information contained in the database of the Spanish Society of Rheumatology. Quality control was performed by contact (e-mail and telephone call) with the heads of the clinical services of each of the hospitals (public and private). The information analysed was the age, sex and place of work of active rheumatologists in February 2020. The rates of rheumatologists per 100,000 inhabitants were calculated from population data from the National Institute of Statistics. RESULTS: The rate of rheumatology specialists per 100,000 inhabitants in Spain was estimated at 2.17. The percentage of women was 59.7%, with a higher female/male ratio at younger ages. The lowest proportion of specialists per 100,000 inhabitants was in the community of Valencia (1.6), and the highest in Cantabria (3.2). CONCLUSIONS: Variations were found in the rate of rheumatologists per 100,000 inhabitants among the Autonomous Communities. The distribution by age and sex showed a tendency towards female rheumatologists, especially in the younger age strata.
