ABSTRACT
Abstract Background Early rheumatoid arthritis (RA) offers an opportunity for better treatment outcomes. In real-life settings, grasping this opportunity might depend on access to specialized care. We evaluated the effects of early versus late assessment by the rheumatologist on the diagnosis, treatment initiation and long-term outcomes of RA under real-life conditions. Methods Adults meeting the ACR/EULAR (2010) or ARA (1987) criteria for RA were included. Structured interviews were conducted. The specialized assessment was deemed "early" when the rheumatologist was the first or second physician consulted after symptoms onset, and "late" when performed afterwards. Delays in RA diagnosis and treatment were inquired. Disease activity (DAS28-CRP) and physical function (HAQ-DI) were evaluated. Student's t, Mann-Whitney U, chi-squared and correlation tests, and multiple linear regression were performed. For sensitivity analysis, a propensity score-matched subsample of early- vs. late-assessed participants was derived based on logistic regression. The study received ethical approval; all participants signed informed consent. Results We included 1057 participants (89.4% female, 56.5% white); mean (SD) age: 56.9 (11.5) years; disease duration: 173.1 (114.5) months. Median (IQR) delays from symptoms onset to both RA diagnosis and initial treatment coincided: 12 (6-36) months, with no significant delay between diagnosis and treatment. Most participants (64.6%) first sought a general practitioner. Notwithstanding, 80.7% had the diagnosis established only by the rheumatologist. Only a minority (28.7%) attained early RA treatment (≤ 6 months of symptoms). Diagnostic and treatment delays were strongly correlated (rho 0.816; p < 0.001). The chances of missing early treatment more than doubled when the assessment by the rheumatologist was belated (OR 2.77; 95% CI: 1.93, 3.97). After long disease duration, late-assessed participants still presented lower chances of remission/low disease activity (OR 0.74; 95% CI: 0.55, 0.99), while the early-assessed ones showed better DAS28-CRP and HAQ-DI scores (difference in means [95% CI]: −0.25 [−0.46, −0.04] and − 0.196 [−0.306, −0.087] respectively). The results in the propensity-score matched subsample confirmed those observed in the original (whole) sample. Conclusions Early diagnosis and treatment initiation in patients with RA was critically dependent on early access to the rheumatologist; late specialized assessment was associated with worse long-term clinical outcomes.
ABSTRACT
Abstract Background Management delays imply worse outcomes in rheumatoid arthritis (RA) and, therefore, should be minimized. We evaluated changes in diagnostic and treatment delays regarding RA in the last decades in Brazil. Methods Adults fulfilling the ACR/EULAR (2010) criteria for RA were assessed. Delays in diagnosis and treatment, and the frequencies of early management initiation within thresholds (windows of opportunity) of 3, 6, and 12 months from symptoms onset were evaluated. The Mann-Kendall trend test, chi-squared tests with Cramer's V effect sizes and analysis of variance were conducted. Results We included 1116 patients: 89.4% female, 56.8% white, mean (SD) age 57.1 (11.5) years. A downward trend was found in diagnostic (tau = - 0.677, p < 0.001) and treatment (tau = - 0.695, p < 0.001) delays from 1990 to 2015. The frequency of early management increased throughout the period, with ascending effect sizes across the 3-, 6-, and 12-month windows (V = 0.120, 0.200 and 0.261, respectively). Despite all improvements, even in recent years (2011-2015) the diagnostic and treatment delays still remained unacceptably high [median (IQR): 8 (4-12) and 11 (5-17) months, respectively], with only 17.2% of the patients treated within the shortest, 3-month window. Conclusion The delays in diagnosis and treatment of RA decreased during the last decades in Brazil. Improvements (effect sizes) were greater at eliminating extreme delays (≥ 12 months) than in attaining really short management windows (≤ 3 months). Very early treatment was still an unrealistic goal for most patients with RA.
ABSTRACT
Abstract Introduction Although Rheumatoid Arthritis (RA) extra-articular manifestations (ExtRA) occurrence has been decreasing over time, they are still a major mortality risk factor for patients. Objective To determine the prevalence of ExtRA in a large cohort, and its association with demographic and clinical variables. Method Cross-sectional and observational study, based on a multi-centric database from a prospective cohort, in which 11 public rheumatology centres enrolled RA patients (1987 ARA or 2010 ACR-EULAR). Data collection began in 08-2015, using a single online electronic medical record. Continuous variables were compared using Mann-Whit-ney U-test, and Fisher's exact test or chi-square test, as appropriate, were used for categorical variables. The level of significance was set at 5% (p < 0.05). Results 1115 patients were included: 89% women, age [mean ± SD] 58.2 ± 11.5 years, disease duration 14.5 ± 12.2 years, positive Rheumatoid Factor (RF, n = 1108) in 77%, positive anti-cyclic citrullinated peptide (ACPA, n = 477) in 78%. Regarding ExtRA, 334 occurrences were registered in 261 patients, resulting in an overall prevalence of 23.4% in the cohort. The comparison among ExtRA and Non-ExtRA groups shows significant higher age (p < 0.001), disease duration (p < 0.001), RF high titers (p = 0.018), Clinical Disease Activity index (CDAI) (p < 0.001), Disease Activity Index 28 (DAS 28) (p < 0.001), and Health Assessment Questionnaire (HAQ) (p < 0.001) in ExtRA group. Treatment with Azathioprine (p = 0.002), Etanercept (p = 0.049) Glucocorticoids (GC) ('p = 0.002), and non-steroidal anti-inflammatory drugs (NSAIDs) (p < 0.001) were more frequent in ExtRA group. Conclusions ExtRA manifestations still show an expressive occurrence that should not be underestimated. Our findings reinforce that long-term seropositive disease, associated with significant disability and persistent inflammatory activity are the key factors related to ExtRA development.
ABSTRACT
Abstract Objectives: To compare the efficacy and safety of a new formulation of a fixed dose combination of glucosamine sulfate (GS; 1500 mg) and bovine chondroitin sulfate (CS; 1200 mg) versus the reference product (RP) in patients with knee osteoarthritis (OA). Methods: In this multicenter, randomized, single-blind trial, 627 patients with knee osteoarthritis (OA)—Kellgren-Lawrence grades 2 or 3 and mean score ≥ 40 mm in the WOMAC pain subscale—were randomized to receive GS/ CS or the RP for 24 weeks. The primary efficacy endpoint was the absolute change in WOMAC pain subscale score. The secondary endpoints included the following: WOMAC total and subscale scores, overall assessment of the disease by the patient and the investigator, SF-12 score, OMERACT-OARSI response rate to the treatment, and rescue medication use. Results: Mean reductions of WOMAC pain score were - 35.1 (sd = 23.2) mm in the GS/CS group and - 36.5 (sd = 24.9) mm in the RP group. The difference between the adjusted means of both treatments confirmed the noninferiority of GS/CS versus the RP. Improvement was observed in pain, stiffness, physical function and total WOMAC score, as well as in overall OA assessment by the patient and the investigator for both groups. No improvement was observed in SF-12. The rate of OMERACT-OARSI responders was 89.4% in GS/CS group and 87.9% in the RP group. Headache and changes in glucose tolerance were the most frequent treatment-related adverse events. Conclusions: The new formulation of a fixed-dose combination of glucosamine sulfate and bovine chondroitin sulfate was non-inferior to the RP in symptomatic treatment of knee OA, with a high responder rate and good tolerability profile.

Abstract Background: Rheumatoid arthritis (RA) is a common autoimmune systemic inflammatory disease. In addition to joint involvement, RA patients frequently have other comorbidities, such as cardiovascular diseases. Drugs used for RA treatment may increase or decrease the risk of a cardiovascular event. This study aims to analyze cardiovascular risk comorbidities in patients with RA and the correlation with the use of anti-rheumatic drugs. Methods: Cross-sectional study conducted based on the real-life rheumatoid arthritis study database - REAL, a prospective observational cohort study. Associations between the use of anti-rheumatic drugs and the presence of comorbidities were represented by their prevalence ratio and evaluated using the Chi-square or Fisher's Exact tests. Results: We assessed 1116 patients, 89.4% women, mean age of 55.15 years and predominance of seropositive disease. 63.3% had some cardiovascular comorbidity, predominantly hypertension (49.9%). The use of glucocorticoids was observed in 47.4% of patients and there was a significant tendency of lower use of these drugs in the presence of dyslipidemia (PR: 0.790; p = 0.007). We observed that the presence of cardiovascular comorbidities was associated with higher use of bDMARDs (PR:1.147; p = 0.003). Conclusions: The presence of cardiovascular risk comorbidities was confirmed to be higher in RA patients. Different treatment strategies using less glucocorticoids in the presence of dyslipidemia and more common use of bDMARDs in patients with cardiovascular comorbidities suggest that rheumatologists are aware of the potential influence of the DMARDs in the risk of cardiovascular event. Reinforcing these results, we highlight the need for a better baseline assessment to guide the choice of anti-rheumatic drugs in RA patients who have comorbidities.
ABSTRACT
Abstract Background: In Brazil, socioeconomic differences in the incidence of rheumatoid arthritis (RA) have been demonstrated, which are important in the formulation of hypotheses regarding the association between environmental factors, lifestyle and the risk of disease development. This study examines how the socioeconomic condition of the patient with RA in Brazil, assessed according to social class, educational level, employment situation and use of caregivers, affects the times between the beginning of symptoms and diagnosis and the beginning of the use of disease-modifying antirheumatic drugs, as well as the presence of erosive disease and functional status. Methods: This work is part of a multicentric study called REAL - Rheumatoid Arthritis in Real Life in Brazil, which is a prospective observational cohort study. Results: As described in the REAL study, we included a total of 1115 patients. It was noted that patients with an educational classification of up to second grade incomplete presented with erosion percentages above those with a higher grade complete. Patients with caregivers presented a higher percentage of erosion than patients without caregivers. We verified that patients from economic classes above B2 presented fewer occurrences of erosion than those from classes C2, D-E. We also analyzed the average time differences from the beginning of symptoms and diagnosis and the beginning of treatment, according to academic level, erosion and economic classification. Patients with first grade complete showed an HAQ-DI averages higher than those with second grade complete. The patients who had employment showed lower HAQ-DI averages than patients who were not employed. The patients with erosion showed an HAQ-DI value higher than those without erosion. Patients with caregivers showed an HAQ-DI average higher than that of without caregivers. Conclusion: This study showed that the therapeutic window of RA is not being reached, and therefore we should have a policy to expand and ensure access to public health for all patients, especially those with lower levels of education and income. Trial registration: This study was approved by the National Commission of Ethics in Research.(AU)

Abstract Background: Last decades witnessed great technological advances in rheumatoid arthritis (RA) management, but their implementation in clinical practice might prove difficult. Despite the efficacy demonstrated in controlled trials this information needs to be confirmed by real life data. This study assessed real-life treatment among RA patients. Methods: REAL study included Brazilian RA patients from eleven centers. Interview and medical records were performed. Continuous variables were compared using Student's t or Mann-Whitney and categorical variables were assessed with chi-square or Fisher's exact tests. Results: 1115 patients were included, women 89.5%. Median age 56.6 years, disease duration 152.5 months; 78.7% were rheumatoid fator positive; 55.2% had erosive disease; DAS28 (disease activity index-28 joints) = 3.5, HAQ (health assessment questionnaire) =0.875. The median duration of symptoms until the start of first DMARD was 12 months. A total of 529 (47.2%) patients used corticosteroids; 1022 (90.8%) were on conventional synthetic (cs) DMARDs and 406 (36.1%) on biological (b) DMARDs. Methotrexate (MTX) was the most frequent csDMARD: 748 (66.5%) patients, followed by leflunomide (LFN), used by 381 (33.9%) of patients. MTX was associated to LFN in 142 (12.6%) patients. Only five (0.4%) patients used triple therapy (MTX + hydroxychloroquine + sulfasalazine) or sulfasalazine in monotherapy. Conclusions: Despite advances in therapeutic resources, roughly half RA patients failed achieve T2T goals and 55.2% developed erosive disease. The frequent use of corticosteroids and delay in initiating DMARDs were demonstrated. Issues concerning timely access to medical care are crucial for effective management.(AU)

Abstract Osteoporosis is the leading cause of fractures in the population older than 50 years. This silent disease affects primarily postmenopausal women and the elderly, and the morbidity and mortality rates are high. The main goal of treating osteoporosis is the prevention of fractures. The identification of populations at risk through early diagnosis and treatment is essential. The last Brazilian guideline for the treatment of postmenopausal osteoporosis was elaborated in 2002. Since then, new strategies for diagnosis and risk stratification have been developed, and drugs with novel action mechanisms have been added to the therapeutic arsenal. The Osteoporosis and Osteometabolic Diseases Committee of the Brazilian Society of Rheumatology, in conjunction with the Brazilian Medical Association and other Societies, has developed this update of the guidelines for the treatment of postmenopausal osteoporosis according to the best scientific evidence available. This update is intended for professionals in many medical and health specialties involved in the treatment of osteoporosis, for physicians in general and for health-related organizations.
Resumo A osteoporose é a principal causa de fraturas na população acima de 50 anos. É uma doença silenciosa que afeta especialmente as mulheres na pós-menopausa e idosos e tem elevada taxa de morbimortalidade. O principal objetivo do tratamento da osteoporose é a prevenção das fraturas. A identificação dessa população de risco através do diagnóstico e tratamento precoces é de fundamental importância. A última diretriz brasileira para tratamento da osteoporose em mulheres na pós-menopausa foi elaborada em 2002. Desde então foram desenvolvidas novas estratégias de diagnóstico da osteoporose, bem como fármacos com novos mecanismos de ação foram adicionados ao arsenal terapêutico. A Comissão de Osteoporose e Doenças Osteometabólicas da Sociedade Brasileira de Reumatologia em conjunto com a Associação Médica Brasileira e sociedades afins desenvolveu esta atualização da diretriz do tratamento da osteoporose em mulheres na pós-menopausa de acordo com as melhores evidências científicas disponíveis. Esta atualização é destinada aos profissionais das várias especialidades médicas e da área da saúde envolvidos no tratamento da osteoporose, médicos em geral e organizações relacionadas à saúde.

Os glicocorticoides (GC) são prescritos por praticamente todas as especialidades médicas, e cerca de 0,5% da população geral do Reino Unido utiliza esses medicamentos. Com o aumento da sobrevida dos pacientes com doenças reumatológicas, a morbidade secundária ao uso dessa medicação representa um aspecto importante que deve ser considerado no manejo de nossos pacientes. As incidências de fraturas vertebrais e não vertebrais são elevadas, variando de 30%-50% em pessoas que usam GC por mais de três meses. Assim, a osteoporose e as fraturas por fragilidade devem ser prevenidas e tratadas em todos os pacientes que iniciarão ou que já estejam em uso desses esteroides. Diversas recomendações elaboradas por várias sociedades internacionais têm sido descritas na literatura, porém não há consenso entre elas. Recentemente, o Americam College of Rheumatology publicou novas recomendações, porém elas são fundamentadas na FRAX (WHO Fracture Risk Assessment Tool) para analisar o risco de cada indivíduo e, dessa maneira, não podem ser completamente utilizadas pela população brasileira. Dessa forma, a Comissão de Osteoporose e Doenças Osteometabólicas da Sociedade Brasileira de Reumatologia, em conjunto com a Associação Médica Brasileira e a Associação Brasileira de Medicina Física e Reabilitação, implementou as diretrizes brasileiras de osteoporose induzida por glicocorticoide (OPIG), baseando-se na melhor evidência científica disponível e/ou experiência de experts. DESCRIÇÃO DO MÉTODO DE COLETA DE EVIDÊNCIA: A revisão bibliográfica de artigos científicos desta diretriz foi realizada na base de dados MEDLINE. A busca de evidência partiu de cenários clínicos reais, e utilizou as seguintes palavras-chave (MeSH terms): Osteoporosis, Osteoporosis/chemically induced*= (Glucocorticoids= Adrenal Cortex Hormones, Steroids), Glucocorticoids, Glucocorticoids/administration and dosage, Glucocorticoids/therapeutic use, Glucocorticoids/adverse effects, Prednisone/adverse effects, Dose-Response Relationship, Drug, Bone Density/drug effects, Bone Density Conservation Agents/pharmacological action, Osteoporosis/ prevention&control, Calcium, Vitamin D, Vitamin D deficiency, Calcitriol, Receptors, Calcitriol; 1-hydroxycholecalciferol, Hydroxycholecalciferols, 25-Hydroxyvitamin D3 1-alpha-hydroxylase OR Steroid Hydroxylases, Prevention and Control, Spinal fractures/prevention & control, Fractures, Spontaneous, Lumbar Vertebrae/injuries, Lifestyle, Alcohol Drinking, Smoking OR tobacco use disorder, Movement, Resistance Training, Exercise Therapy, Bone density OR Bone and Bones, Dual-Energy X-Ray Absorptiometry OR Absorptiometry Photon OR DXA, Densitometry, Radiography, (Diphosphonates Alendronate OR Risedronate Pamidronate OR propanolamines OR Ibandronate OR Zoledronic acid, Teriparatide OR PTH 1-34, Men AND premenopause, pregnancy, pregnancy outcome maternal, fetus, lactation, breast-feeding, teratogens, Children (6-12 anos), adolescence (13-18 anos). GRAU DE RECOMENDAÇÃO E FORÇA DE EVIDÊNCIA: A) Estudos experimentais e observacionais de melhor consistência; B) Estudos experimentais e observacionais de menor consistência; C) Relatos de casos (estudos não controlados); D) Opinião desprovida de avaliação crítica, com base em consensos, estudos fisiológicos ou modelos animais. OBJETIVO: Estabelecer as diretrizes para a prevenção e o tratamento da OPIG.
Glucocorticoids (GC) are used in almost all medical specialties, and approximately 0.5% of the general population of the United Kingdom receives those medications. With the increased survival of patients with rheumatological diseases, morbidity secondary to the use of those medications represents an important aspect of the management of our patients. The incidences of vertebral and non-vertebral fractures are elevated, ranging from 30% to 50% of the individuals on GC for over three months. Thus, osteoporosis and frailty fractures should be prevented and treated in all patients initiating or already on GC. There are several recommendations on this topic elaborated by several international societies, but consensus still lacks. Recently, the American College of Rheumatology has published new recommendations, but they are based on the WHO Fracture Risk Assessment Tool (FRAX®) to evaluate the risk for each individual, and, thus, cannot be completely used for the Brazilian population. Thus, the Committee for Osteoporosis and Bone Metabolic Disorders of the Brazilian Society of Rheumatology, along with the Brazilian Medical Association and the Brazilian Association of Physical Medicine and Rehabilitation, has elaborated the Brazilian Guidelines for Glucocorticoid-Induced Osteoporosis (GIO), based on the better available scientific evidence and/or expert experience. METHOD OF EVIDENCE COLLECTION: The bibliographic review of scientific articles of this guideline was performed in the MEDLINE database. The search for evidence was based on real clinical scenarios, and used the following keywords (MeSH terms): Osteoporosis, Osteoporosis/ chemically induced*= (Glucocorticoids= Adrenal Cortex Hormones, Steroids), Glucocorticoids, Glucocorticoids/administration and dosage, Glucocorticoids/therapeutic use, Glucocorticoids/adverse effects, Prednisone/adverse effects, Dose-Response Relationship, Drug, Bone Density/drug effects, Bone Density Conservation Agents/pharmacological action, Osteoporosis/prevention & control, Calcium, Vitamin D, Vitamin D deficiency, Calcitriol, Receptors, Calcitriol; 1-hydroxycholecalciferol, Hydroxycholecalciferols, 25-Hydroxyvitamin D3 1-alpha-hydroxylase OR Steroid Hydroxylases, Prevention and Control, Spinal fractures/prevention & control, Fractures, Spontaneous, Lumbar Vertebrae/injuries, Lifestyle, Alcohol Drinking, Smoking OR tobacco use disorder, Movement, Resistance Training, Exercise Therapy, Bone density OR Bone and Bones, Dual-Energy X-Ray Absorptiometry OR Absorptiometry Photon OR DXA, Densitometry, Radiography, (Diphosphonates Alendronate OR Risedronate Pamidronate OR propanolamines OR Ibandronate OR Zoledronic acid, Teriparatide OR PTH 1-34, Men AND premenopause, pregnancy, pregnancy outcome maternal, fetus, lactation, breast-feeding, teratogens, Children (6-12 years), adolescence (13-18 years). GRADE OF RECOMMENDATION AND LEVEL OF EVIDENCE: A) Data derived from more consistent experimental and observational studies; B) Data derived from less consistent experimental and observational studies; C) Case reports (uncontrolled studies); D) Expert opinion without explicit critical appraisal, or based on consensus, physiological studies or animal models. OBJECTIVE: To establish guidelines for the prevention and treatment of GIO.

OBJETIVOS: Este estudo visou à análise das manifestações da esclerose sistêmica (ES), com ênfase na pesquisa dos autoanticorpos e de suas correlações clínicas, na população de pacientes em acompanhamento no ambulatório de ES do Hospital de Clínicas da Universidade Federal do Paraná. METODOLOGIA: Realizou-se um estudo transversal com 96 pacientes em acompanhamento no ambulatório de ES do hospital, entre setembro de 2007 e setembro de 2009. RESULTADOS: A maioria dos pacientes era do sexo feminino, com idade entre a quarta e quinta décadas e tempo de doença com mediana de 10 anos. A forma cutânea limitada de ES foi a mais prevalente. Na análise dos autoanticorpos, o anticorpo anticentromérico (ACA) associou-se a ES forma limitada, idade mais avançada ao diagnóstico, maior tempo de doença, intervalo maior entre o surgimento do fenômeno de Raynaud (FRy) e o primeiro sintoma não FRy, maior prevalência de hipertensão arterial sistêmica (HAS) e de bloqueios de condução cardíaca. O anticorpo antitopoisomerase-1 (antitopo-1, previamente denominado anti-Scl-70) foi mais comum na forma difusa da ES, na presença de doença ativa e de úlceras digitais. O anticorpo anti-RNA polimerase III (antipol III) correlacionou-se com a forma difusa de ES, presença de doença ativa e sinovite. CONCLUSÕES: Este estudo vem ressaltar e ratificar o papel relevante dos autoanticorpos na avaliação dos pacientes com ES, sendo possível correlacionar o perfil autoimune dessa população com manifestações específicas da doença.
OBJECTIVES: To assess the manifestations of systemic sclerosis (SSc), with an emphasis on the analysis of autoantibodies and their clinical correlations, in a population of patients followed up at the SSc Outpatient Clinics of the Hospital de Clínicas of the Universidade Federal do Paraná. METHODOLOGY: Cross-sectional study with 96 patients followed up at the SSc Outpatient Clinics of the hospital between September 2007 and September 2009. RESULTS: Most patients were of the female sex, in their forties or fifties, and the median time of disease was ten years. The limited cutaneous form of SSc was more prevalent. The analysis of the autoantibodies showed the association of anticentromere antibody (ACA) with the following: the limited form of SSc; more advanced age at the time of diagnosis; longer disease time; longer interval between the appearance of the Raynaud's phenomenon (RyP) and the first non-RyP symptom; systemic arterial hypertension (SAH); and cardiac conduction blocks. The antitopoisomerase-1 antibody (ATA-1, previously called anti-Scl-70) was more common in the presence of the diffuse form of SSc, active disease, and digital ulcers. The anti-RNA polymerase III antibody (anti-Pol III) correlated with the diffuse form of SSc, disease activity, and synovitis. CONCLUSIONS: This study emphasizes and confirms the important role of autoantibodies in assessing patients with SSc, allowing the correlation between the autoimmune profile of patients with SSc and specific manifestations of the disease.

Arterite de Takayasu (AT) é uma doença rara caracterizada por vasculite dos grandes vasos, principalmente aorta e seus ramos. A inflamação vascular leva a irregularidades na parede do vaso, causando estenoses e aneurismas. O envolvimento da artéria pulmonar (AP) é freqüente na AT. Apesar disso, o desenvolvimento de hipertensão arterial pulmonar (HAP) é menos comum, alterando o tratamento e o prognóstico dos pacientes. Descrevemos um caso de uma paciente com AT com estenoses múltiplas em artérias pulmonares, HAP e doença cerebrovascular, além de revisão de literatura sobre o assunto.
Takayasu arteritis (TA) is a rare illness characterized by vasculitis of great vessels, mainly of aorta and its branches. The vascular inflammation leads to irregularities of the vessel wall causing stenosis and aneurysms. The pulmonary artery (PA) involvement is frequent in TA. Despite this, the development of pulmonary arterial hypertension is less common, modifying the treatment and the prognosis of the patients. We describe a case of a patient with TA with multiple stenosis in pulmonary arteries, pulmonary arterial hypertension and cerebrovascular disease, as well as review of the literature on the subject.

Introdução: A osteoartrose (OA) é uma doença idiopática, multífatorial, caracteriza- da por uma lenta e progressiva degradação da cartilagem articular. Objetivo: Avaliar a eficácia e segurança dos insaponificáveis de abacate e soja (IAS) no tratamento de pacientes com osteoartrose sintomática (OA) do joelho e do quadril. Métodos: Foram incluídos 231 pacientes de ambos os sexos, com idade entre 45 e 75 anos, que apresentavam osteoartrose sintomática de joelho e/ou quadril confirmadas, clínica e radiologicamente, pelos Critérios do Colégio Americano de Reumatologia. Entraram em um estudo aberto, não randomizado, multicentrico, controlado, com um período de tratamento de seis meses. Um intervalo de 15 dias (Washout) para drogas antiinflamatórias não esteroidais (AINEs) precedeu o estudo. A eficácia foi julgada de acordo com: 1) índice Funcional de Lequesne (IFL); e 2) dor na Escala Visual Analógica (EVA; escala de 100 mm)" íngestão de AINElanalgésícos e escore de incapacidade total (pela EVA de 100 mm). Resultados: 231 pacientes receberam os IAS. Os dados de todos os pacientes encontravam-se disponíveis para avaliação no mês 6. A média +/- SEM no escore do IFL diminuiu de 11,88+/-0,24 para 6,84 +/- 0,29 no final de 6 meses (p < 0,001). A dor diminuiu de 6,65+/- 0, 11 mm para 3,21 +/- 0,17 mm (p < 0, 00 1). O consumo de A INES diminuiu de 1,95 +/- 0,10 para 0,67 +/- 0,14 (p <0,001) ao final de 6 meses. A taxa de sucesso foi de 42,3por cento no grupo de IAS ao final de 6 meses. A incapacidade funcional total foi signifícativamente reduzida no grupo IAS. A tolerância foi de boa a excelente para a maioria dos pacientes. Conclusão: Os IAS, neste estudo aberto, controlado e multícêntrico, mostrou ser seguro e eficaz, no controle sintomático da osteoartrose de quadril e de joelho. Estudos mais prolongados, com metodologias mais avançadas, na procura de desvendar seus mecanismos de ação ainda são necessários

Objetivo: investigar se o aumento de produtos de ativação do complemento estão associados com a atividade e as manifestações clínicas da doença em pacientes com lúpus eritematoso sistêmico (LES). Comparações com outros marcadores convencionais do complemento e do processo inflamatório foram realizadas. Métodos: as concentrações plasmáticas de SC5b-9, C3a desArg, C1rs-C1 Inibidor e C3b(Bb)P foram determinadas através de ELISA. Os níveis de C3 e C4 foram avaliados através de turbidimetria e a velocidade de hemossedimentação (VHS) e mucoproteínas (MP), de acordo com técnicas-padrão. Foram estudados 41 pacientes com LES, que apresentavam os seguintes graus de atividade da doença: sem atividade (n = 10), com atividade leve (n = 15) e com atividade moderada ou grave (n = 16). Resultados: todos os parâmetros, exceto C3 e C3b(Bb)P, mostraram uma associação estatisticamente significante com a atividade da doença. As concentrações de SC5b-9, C3adesArg, C4, CH50, VHS e MP mostraram diferenças significativas entre os pacientes sem atividade clínica e aqueles com atividade moderada/ grave. Embora nenhum parâmetro tenha sido capaz de diferenciar pacientes com atividade leve daqueles sem atividade, SC5b-9, C3adesArg, C4, VHS e MP apresentaram diferenças significativas entre os pacientes com atividade leve e moderada/ grave. Dentre os parâmetros estudados, a concentração de SC5b-9 mostrou resultados mais significativos, quando associado à gravidade da doença (p 0,0005). Conclusões: os resultados sugerem que produtos de ativação do complemento, particularmente SC5b-9, são marcadores mais sensíveis na avaliação da atividade do LES do que marcadores convencionais, e que técnicas mais modernas para avaliação do complemento são recomendadas no monitoramento do paciente com LES.

Objetivos - Analisar a variabilidade genética dos componentes C3 e BF do sistema complemento em pacientes brasileiros portadores de lúpus eritematoso sistêmico (LES) e as possíveis associações entre suas formas alotípicas e determinadas manifestações clínicas e laboratoriais da doença. Pacientes e métodos - O estudo foi realizado em 95 pacientes portadores de LES (88 mulheres e 7 homens, com variação etária de 14 a 57 anos, média de 30,18 anos), segundo os critérios de classificação do Colégio Americano de Reumatologia, e em 89 controles sadios. Os alótipos de C3 e de BF foram detectados no soro dos pacientes e controles através de eletroforese de alta voltagem em gel agarose, seguido de imunofixação com anticorpo específico. Resultados - Os alótipos de C3 e BF observados no presente estudo foram: C3S, C3F, C3SF, C3SS05 e BFS, BFF, BFSSF, BFSF1, BFSF075, BFSS07, BFF1. Os resultados obtidos demonstrarem aumento do alótipo BFF nos pacientes, quando comparados com os controles normais (p= 0,055; RR = 2,87); para os demais alótipos, não houve diferença signifiante quanto à sua distribuição. Menor frequência do alótipo BFS foi observada nos pacientes que apresentaram manifestações neurológicas, em relação aos que não as tiveram (p=0,059); RR = 0,28). Também nos pacientes que apresentaram serosites, observou-se frequência diminuída dos alótipos C3S e BFS, quando comparados com os que naõ apresentaram esta manifestação durante o curso da doença (p=0,036 para C3 e p=0,021 para BF; RR = 0,38 para ambos). Conclusões - A frequência diminuída de BFS nos pacientes com manifestações neurológicas e de C3S e BFS nos que apresentaram serosites no curso da doença sugere associação negativa e possível papel protetor desses alótipos no desenvolvimento dessas manifestações clínicas no LES. Os achados aqui descritos sugerem que a variabilidade genetica das proteínas C3 e BF do sistema complemento pode estar relacionada com o mecanismo etiopatogênico e com a expressão clínica do LES em pacientes brasileiros

Objetivo: Analisar os resultados da artroplastia total de joelho em pacientes portadores de artrite reumatóide, tratados no Serviço Integrado de Reumato-Ortopedia (SIRO) do Hospital de Clínicas da Universidade Federal do Paraná, em Curitiba. Métodos: Foi realizado estudo retrospectivo, no período de julho de 1985 a abril de 1991, em 16 pacientes portadores de artrite reumatóide. A idade média dos pacientes no momento da operaçao foi de 41,3 anos. O tempo de seguimento pós-operatório foi de no mínimo dois anos e no máximo de sete anos e oito meses (média de três anos e 11 meses). Resultados: Na última avaliaçao, 23 joelhos (92 por cento) tiveram resultado classificado como bom, um (4 por cento) regular e um (4 por cento) mau. Houve caso de soltura asséptica da prótese que necessitou reoperaçao para troca dos componentes. Conclusao: O principal efeito da operaçao foi o alívio da dor dos pacientes. A artroplastia total de joelho em pacientes reumatóides, apesar da baixa idade em que foi indicada e da fragilidade óssea típica deste grupo de pacientes, mostrou alta percentagem de bons resultados, com tempo de seguimento pós-operatório médio de três anos e 11 meses
