RESUMO

To assess the hypothesis if tocilizumab (TCZ) is effective on disease activity, and also its effect in fatigue and other clinical and psychological disease-related factors in patients with rheumatoid arthritis (RA) treated with TCZ.A 24-week, multicenter, prospective, observational study in patients with moderate to severe RA receiving TCZ after failure or intolerance to disease-modifying antirheumatic drugs or tumor necrosis factor-alpha was conducted.Of the 122 patients included, 85 were evaluable for effectiveness (85% female, 51.9 ±â€Š12.5 years, disease duration 8.7 ±â€Š7.4 years). Mean change in C-reactive protein level from baseline to week 12 was -11.2 ±â€Š4.0 (P < .001). Mean Disease Activity Index score (DAS28) decreased from 5.5 ±â€Š1.0 at baseline to 2.7 ±â€Š1.3 (P < .001) at week 24. Mean change in Functional Assessment of Chronic Illness Therapy score was -5.4 ±â€Š11.2 points at week 24. Multiple regression analysis showed that the improvement in DAS28, sleep, and depression explained 56% and 47% of fatigue variance at week 12 and 24, respectively.Tocilizumab is effective in reducing disease activity and results in a clinically significant improvement in fatigue, pain, swollen joint count, morning stiffness, sleepiness, depression, and DAS28; the last 3 were specifically identified as factors explaining fatigue variance with the use of TCZ in RA patients.

RESUMO

BACKGROUND: Recent data suggest that anti-TNF doses can be reduced in ankylosing spondylitis (AS) patients. Some authors even propose withdrawing treatment in patients in clinical remission; however, at present there is no evidence to support this. OBJECTIVE: To assess how long AS patients with persistent clinical remission remained free of flares after anti-TNF withdrawal and to evaluate the effects of treatment reintroduction. We also analyze the characteristics of patients who did not present clinical relapse. METHODS: Multicenter, prospective, observational study of a cohort of patients with active AS who had received infliximab as a first anti-TNF treatment and who presented persistent remission (more than 6 months). We recorded at baseline and every 6-8 weeks over the 12-month period the age, gender, disease duration, peripheral arthritis or enthesitis, HLA-B27 status, BASDAI, CRP, ESR, BASFI, and three visual analogue scales, spine global pain, spinal night time pain, and patient's global assessment. RESULTS: Thirty-six out of 107 patients (34%) presented persistent remission and were included in our study. After treatment withdrawal, 21 of these 36 patients (58%) presented clinical relapse during follow-up. Infliximab therapy was reintroduced and only 52% achieved clinical remission, as they had before the discontinuation of infliximab; in an additional 10%, reintroduction of infliximab was ineffective, obliging us to change the anti-TNF therapy. No clinical or biological factors were associated with the occurrence of relapse during the follow-up. CONCLUSIONS: Two thirds of patients in clinical remission presented clinical relapse shortly after infliximab withdrawal. Although the reintroduction of infliximab treatment was safe, half of the patients did not present the same clinical response that they had achieved prior to treatment withdrawal.

RESUMO

BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that affects multiple organs and systems. B cells have a critical role in the pathogenesis of SLE. Rituximab (RTX) is a drug composed of chimeric monoclonal antibodies against the CD20 protein, producing a depletion of B lymphocytes. OBJECTIVE: To analyze the effectiveness and safety of RTX in patients with SLE in clinical practice. METHODS: Collection of retrospective variables of the medical records of 20 patients with SLE treated with RTX in 2hospitals (Hospital de la Santa Creu i Sant Pau, and Hospital del Mar, in Barcelona, Spain). We evaluated demographic, clinical, serological and treatment variables. RESULTS: There was a statistically significant association in the following variables collected in the study before and after treatment: there was a decrease in the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) (P<.001), erythrocyte sedimentation rate (P=.017), use of glucocorticoids (P=.025) and IgM values (P=.031), as well as an increase in the C4 values (P=.014) after treatment with RTX. A patient with SLE, antiphospholipid syndrome, complex comorbidity and multiorgan lupus involvement died after developing a septic process, months after receiving a single treatment cycle with RTX. CONCLUSIONS: Although RTX currently has no official indication approved for SLE, our data suggest that it may be effective in reducing the activity of the disease and as a steroid-sparing agent, with an acceptable safety profile. However, larger follow-up periods with a greater number of patients are needed to solve the remaining doubts about the use of RTX in SLE.

RESUMO

AIMS: To describe the methodology of REAPSER (Spanish Registry of Recent-onset Psoriatic Arthritis), its strengths and limitations. The aim of this study is to identify prognostic factors for the clinical and radiographic course in a cohort of patients with psoriatic arthritis (PsA) diagnosed within 2years of symptom evolution. METHODS: Multicenter, observational and prospective study (with 2-year follow-up including annual visits). Baseline visit intended to reflect patient situation before the disease course was modified by treatments prescribed in rheumatology departments. Patients were invited to participate consecutively in one of their routine visits to the rheumatologist. 211 patients were included. Following data were collected: sociodemographic variables; employment situation; family history; personal history and comorbidities; anthropometric data; lifestyle; use of healthcare services; clinical situation at the time of PsA diagnosis; joint involvement and spinal pain; pain and overall assessment; enthesitis, dactylitis and uveitis; skin and nail involvement; functional situation and quality of life; radiographic evaluation; analytical determinations; treatment; axial and peripheral flare-ups. CONCLUSIONS: The REAPSER study includes a cohort of patients with recent-onset PsA, before the disease course was modified by disease-modifying antirheumatic drugs prescribed in rheumatology departments. Exhaustive information collected in each visit is expected to be an important data source for future analysis.

RESUMO

Ultrasonography has been rarely used to measure musculoskeletal and joint activity in systemic lupus erythematosus (SLE). The aim of this review is to discuss the utility and reliability of this non-invasive diagnostic tool for the assessment of joint disease in SLE patients. In the last decade, several reports have highlighted the role of ultrasonography for a better evaluation of SLE-related musculoskeletal symptoms. The symptoms have also been associated with worse outcomes in SLE; therefore, it is essential to seek useful and accessible techniques for better understanding of such patients who are insufficiently assessed by standard physical examination.

RESUMO

OBJECTIVES: The aim of this study was to adapt the Systemic Sclerosis Quality of Life Questionnaire (SScQoL) into six European cultures and validate it as a common measure of quality of life in systemic sclerosis (SSc). METHODS: This was a seven-country (Germany, France, Italy, Poland, Spain, Sweden and UK) cross-sectional study. A forward-backward translation process was used to adapt the English SScQoL into target languages. SScQoL was completed by patients with SSc, then data were validated against the Rasch model. To correct local response dependency, items were grouped into the following subscales: function, emotion, sleep, social and pain and reanalysed for fit to the model, unidimensionality and cross-cultural equivalence. RESULTS: The adaptation of the SScQoL was seamless in all countries except Germany. Cross-cultural validation included 1080 patients with a mean age 58.0 years (SD 13.9) and 87% were women. Local dependency was evident in individual country data. Grouping items into testlets corrected the local dependency in most country specific data. Fit to the model, reliability and unidimensionality was achieved in six-country data after cross-cultural adjustment for Italy in the social subscale. The SScQoL was then calibrated into an interval level scale. CONCLUSION: The individual SScQoL items have translated well into five languages and overall, the scale maintained its construct validity, working well as a five-subscale questionnaire. Measures of quality of life in SSc can be directly compared across five countries (France, Poland Spain, Sweden and UK). Data from Italy are also comparable with the other five countries although require an adjustment.

RESUMO

Despite the improvement in the quality of life of patients with SLE due to scientific and technological advances, SLE remains a disease that over the years may produce irreversible damage to patients. Osteoporosis and secondary bone fractures are two of the major causes of irreparable injury in patients with SLE. Vitamin D insufficiency may play a vital role both in reduced bone mineral density (BMD) and in the appearance of fractures, although its mechanisms of action are still unclear. We performed a systematic review of the literature in order to determine the prevalence and predictors of reduced vitamin D plasma levels, bone loss and the presence of fractures in SLE patients. Our review encompassed all English-language publications using Medline and EMBase electronic databases from their inception (1966 and 1980, respectively) to December 2016. We included all intervention studies and observational studies in which vitamin D plasma levels, BMD and bone loss were measured and applied to patients with SLE. Previous studies suggested an increase in bone loss and fracture in patients with SLE compared with general population and although there is a high prevalence of vitamin D insufficiency in the general population, previous studies had demonstrated lower vitamin D levels in patients with SLE compared to age-matched controls. The etiology of reduced bone mass and reduced vitamin D plasma levels in SLE is multifactorial and includes a variety of intrinsic factors related to the disease itself and treatment side effects. SLE patients are at risk for developing these two comorbidities (reduced vitamin D plasma levels and low BMD) and it is therefore essential to study, monitor, prevent and treat bone metabolism disorders in SLE patients.

RESUMO

OBJECTIVES: We aimed to describe juvenile-onset systemic lupus erythematosus (jSLE) features and to establish its differences compared to adult-onset SLE (aSLE) from a large national database. METHODS: Data from patients (≥4 ACR criteria) included in Spanish Society of Rheumatology Lupus Registry (RELESSER) were analysed. Sociodemographic, clinical, serological, activity, treatment, cumulative damage, comorbidities and severity data were collected. Patients with disease onset <18 years were described and compared to those with disease onset ≥18 years. RESULTS: We reviewed 3,428 aSLE patients (89.6% women) and 484 jSLE patients (89.8% girls), 93% Caucasian (both groups). Mean age at diagnosis was 38.1±14 and 16.6±6.3 years (p<0.001) and mean age at the end of follow-up was 48.8±14.3 and 31.5±30 years (p<0.001), respectively. jSLE showed significantly more clinical (including lymphadenopathy, fever, malar rash, mucosal ulcers, pericarditis, pleuritis, Raynaud's phenomenon, lupus nephritis, recurrent nephritis, histologic nephritis changes, thrombocytopenia, haemolytic anaemia, thrombotic thrombocytopenic purpura, seizures, lupus headache and organic brain syndrome) and immunological (a-dsDNA and a-Sm antibodies, hypocomplementaemia) involvement than did aSLE, except for secondary Sjögren's syndrome, a-Ro antibodies, fibromyalgia and osteoporosis. jSLE also showed more SLE family history, longer diagnosis delay, higher SLEDAI and Katz scores, but lower Charlson scores than aSLE. Several specific domains were more frequently involved in SLICC/ACR DI in jSLE. jSLE patients more frequently underwent all SLE-related treatment and procedures, as well as dialysis and kidney transplantations. CONCLUSIONS: jSLE shares many clinical and serological features with aSLE. However, jSLE patients typically manifested more activity, severity, cumulative damage in certain areas, than their aSLE counterparts.

RESUMO

OBJECTIVES: To assess fibromyalgia (FM) prevalence in a large cohort of primary Sjögren's syndrome patients (pSS) from a National Database. METHODS: Data included in the national retrospective register of pSS patients of the Spanish Society of Rheumatology (SJOGRENSER) were analysed. RESULTS: 437 pSS patients were included and a 14.6% of FM prevalence was found. FM-pSS patients significantly showed more constitutional, fatigue and arthralgia symptoms, splenomegaly, genital, skin and ear involvement and dyslipidaemia (p<0.05), as well as higher ESSPRI and SSDAI scores (p<0.01). Several symptomatic treatments were more frequently used in FM-pSS patients. No differences were observed in laboratory markers, imaging techniques or histologic inflammatory findings. Patients with FM showed statistically more fatigue than pSS without FM. In the multivariate logistic regression analysis several features were associated to pSS-FM patients. CONCLUSIONS: We show data on a reliable prevalence of FM in pSS patients and its multiple associated factors along with the presence of higher disease activity scores than patients who did not show FM. The presence of fatigue, arthralgia, constitutional symptoms and dyslipidaemia were more likely to coexist in pSS-FM patients.

RESUMO

Primary Sjögren syndrome (PSS) is a chronic inflammatory autoimmune disease. Interstitial lung disease (ILD) can be an extraglandular complication. Objective. To evaluate the clinical characteristics of patients diagnosed with PSS with ILD. Methods. Multicentre cohort study with 25 patients diagnosed with PSS and ILD. Data of PSS, prognostic factors, pulmonary involvement variables, complementary tests that suggest a worse diagnosis and treatment given were collected. EULAR index was measured for Sjögren's syndrome. Results. We identified 25 patients. In 15/25 the diagnosis of ILD was done before the diagnosis of PSS. The histopathological patterns found were: 12 NSIP, 5 UIP, 4 OP, 2 LIP. PFRs showed restrictive pattern. The majority of the patients received glucocorticoid therapy, antimalarial or immunosuppressive treatment. Conclusions. Patients affected with PSS must be screened to catch a precocious diagnosis of ILD. The majority of the patients were diagnosed of ILD before being diagnosed of PSS. Multicenter cohorts are increasingly demanded and a multidisciplinary management is needed (AU)


El síndrome de Sjögren primario (SSP) es una enfermedad inflamatoria autoinmune. La enfermedad pulmonar intersticial (EPI) puede ser una complicación extraglandular. Objetivo. Evaluar las características clínicas de los pacientes diagnosticados de SSP con EPI. Métodos. Estudio de cohortes multicéntrico con 25 pacientes diagnosticados de SSP y EPI. Se recopilaron datos propios del SSP, factores pronóstico, variables de medida de la afectación pulmonar, pruebas complementarias que sugieren un peor pronóstico, así como el tratamiento recibido. Se calculó el índice EULAR para el síndrome de Sjögren. Resultados. Se identificaron 25 pacientes. Quince de ellos fueron diagnosticados de EPI antes que de SSP. Los patrones histopatológicos encontrados fueron 12 con neumonía intersticial inespecífica, 5 con neumonía intersticial común, 4 con neumonía organizada, 2 con neumonía intersticial linfocítica. Las pruebas de función respiratoria mostraron un patrón restrictivo. La mayoría de los pacientes recibió un tratamiento con glucocorticoides, antipalúdicos o inmunodepresores. Conclusiones. Los pacientes afectados por SSP deben ser sometidos a pruebas para detectar un diagnóstico precoz de EPI. La mayoría de los pacientes fueron diagnosticados de EPI antes que de SSP. Los estudios de cohortes multicéntricos son cada vez más demandados y se precisa una gestión multidisciplinar (AU)

RESUMO

Objetivo. Analizar el retraso diagnóstico y terapéutico en pacientes con AR de reciente comienzo en 19 centros de Catalunya. Métodos. Encuesta epidemiológica en 183 pacientes en que se cuantificaron los tiempos en relación con el retraso diagnostico midiendo: 1) aparición del primer síntoma hasta la primera visita a Reumatología; 2) desde la derivación hasta la primera visita de Reumatología; 3) entre aparición del primer síntoma hasta el diagnóstico, y 4) entre aparición del primer síntoma hasta el inicio del primer FAME. Se definió la existencia de 6 dispositivos asistenciales diferenciados. Resultados. El tiempo medio desde el inicio de los síntomas hasta la instauración de un FAME en pacientes con AR en Catalunya es muy largo (11 meses). Pacientes atendidos en dispositivos como consultas de AR, consultas especializadas en atención primaria y sobre todo en consultas de artritis de inicio son tratados de manera más temprana con FAME. Conclusión. La existencia de determinados dispositivos asistenciales es fundamental para mejorar la atención precoz en la AR (AU)


Objective. Diagnosis and therapy of patients with early onset rheumatoid arthritis (RA) is influenced by accessibility to specialized care devices. We attempted to analyze the impact of their availability. Methods. We analyzed time related to diagnosis delay measuring: 1) Time from first clinical symptoms to the first visit with the Rheumatologist; 2) Time from referral to the first visit of Rheumatology; 3) Time between first symptom until final diagnosis; 4) time between first symptom until the initiation of the first disease-modifying antirheumatic drug (DMARD). The presence of these 6 rheumatology devices was defined: 1) early arthritis monographic clinics, 2) RA monographic clinics, 3) Mechanisms for fast programming, 4) Algorithms for referral from primary care (PC), 5) rheumatology consultation services in PC and 6) consulting services in PC. Results. The mean time from onset of symptoms to diagnosis or the establishment of a DMARD in RA patients in Catalonia is very long (11 months). Patients seen in rheumatology devices such as RA monographic clinics, rheumatology consultation in PC and specially in early arthritis clinics are treated early with DMARDs. Conclusion. the existence of monographic clinics or consulting in primary care centers is essential to improve early care of RA patients (AU)

RESUMO

It has been previously reported that vitamin D deficiency is more prevalent among SLE patients than in the general population. We sought to determine the prevalence of vitamin D insufficiency and deficiency and their related factors, its relationship to SLE symptoms and disease activity on a group of supplemented and non-supplemented female SLE patients from the Mediterranean region. We performed a cross-sectional study including female SLE patients who regularly attended the outpatient Lupus Unit at Parc de Salut Mar-IMAS in Barcelona, from January 2012 to May 2014. Collected data were sociodemographics, vitamin D supplementation, fatigue degree visual analog scale, pharmacological treatment, main SLE serological markers, indexes, scales and plasma levels of 25-hydroxyvitamin D. One hundred and two consecutive female SLE patients were included. Vitamin D overall insufficiency and deficiency were exhibited by 46 and 22.5 % of patients, respectively. Vitamin D insufficiency was found in 50 % of supplemented and 60 % of non-supplemented patients. Among non-supplemented female SLE patients, it was found that patients with vitamin D insufficiency showed more fatigue (p = 0.009) and received more oral corticosteroids (p = 0.02) than those with normal levels. Patients with vitamin D insufficiency (supplemented and non-supplemented) received more oral corticosteroids than those without insufficiency (p = 0.008). Vitamin D insufficiency is highly prevalent among female SLE patients, even in southern regions. Non-supplemented female SLE patients showed more fatigue and received more oral corticosteroids than those with normal levels of vitamin D. These data were not found in supplemented patients although having a high prevalence of vitamin D insufficiency (up to 50 %). Further studies with longer follow-up and larger population are needed to confirm our observations.
