Work disability remains a major problem in rheumatoid arthritis in the 2000s: Data from 32 countries in the QUEST-RA Study

IntroductionWork disability is a major consequence of rheumatoid arthritis (RA), associated not only with traditional disease activity variables, but also more significantly with demographic, functional, occupational, and societal variables. Recent reports suggest that the use of biologic agents offers potential for reduced work disability rates, but the conclusions are based on surrogate disease activity measures derived from studies primarily from Western countries.MethodsThe Quantitative Standard Monitoring of Patients with RA (QUEST-RA) multinational database of 8,039 patients in 86 sites in 32 countries, 16 with high gross domestic product (GDP) (>24K US dollars (USD) per capita) and 16 low-GDP countries (<11K USD), was analyzed for work and disability status at onset and over the course of RA and clinical status of patients who continued working or had stopped working in high-GDP versus low-GDP countries according to all RA Core Data Set measures. Associations of work disability status with RA Core Data Set variables and indices were analyzed using descriptive statistics and regression analyses.ResultsAt the time of first symptoms, 86% of men (range 57%-100% among countries) and 64% (19%-87%) of women <65 years were working. More than one third (37%) of these patients reported subsequent work disability because of RA. Among 1,756 patients whose symptoms had begun during the 2000s, the probabilities of continuing to work were 80% (95% confidence interval (CI) 78%-82%) at 2 years and 68% (95% CI 65%-71%) at 5 years, with similar patterns in high-GDP and low-GDP countries. Patients who continued working versus stopped working had significantly better clinical status for all clinical status measures and patient self-report scores, with similar patterns in high-GDP and low-GDP countries. However, patients who had stopped working in high-GDP countries had better clinical status than patients who continued working in low-GDP countries. The most significant identifier of work disability in all subgroups was Health Assessment Questionnaire (HAQ) functional disability score.ConclusionsWork disability rates remain high among people with RA during this millennium. In low-GDP countries, people remain working with high levels of disability and disease activity. Cultural and economic differences between societies affect work disability as an outcome measure for RA.

OBJETIVO: Elaborar recomendacoes para o manejo da artrite reumatoide (AR) no Brasil, com enfoque no diagnostico e na avaliacao inicial da doenca. METODO: Revisao da literatura e opiniao de especialistas membros da Comissao de AR da Sociedade Brasileira de Reumatologia. RESULTADOS E CONCLUSOES: Foram estabelecidas 10 recomendacoes: 1) O diagnostico da AR deve ser estabelecido considerando-se achados clinicos e exames complementares; 2) Deve-se dedicar especial atencao ao diagnostico diferencial dos casos de artrite; 3) O fator reumatoide (FR) e um teste diagnostico importante, porem com sensibilidade e especificidade limitadas, sobretudo na AR inicial; 4) O anti-CCP (teste para anticorpos antipeptideos citrulinados ciclicos) e um marcador com sensibilidade semelhante a do FR, mas com especificidade superior, sobretudo na fase inicial da doenca; 5) Embora inespecificas, provas de atividade inflamatoria devem ser solicitadas a pacientes com suspeita clinica de AR; 6) A radiografia convencional deve ser empregada para avaliacao de diagnostico e prognostico da doenca. Quando necessario e disponivel, a ultrassonografia e a ressonância magnetica podem ser utilizadas; 7) Podem-se utilizar criterios de classificacao de AR (ACR/EULAR 2010), embora ainda nao validados, como um guia para auxiliar no diagnostico de pacientes com artrite inicial; 8) Deve-se utilizar um dos indices compostos para avaliacao de atividade de doenca; 9) Recomenda-se a utilizacao regular de ao menos um instrumento de avaliacao da capacidade funcional; 10) Deve-se verificar, na avaliacao inicial da doenca, a presenca ou nao de fatores de pior prognostico, como o acometimento poliarticular, FR e/ou anti-CCP em titulos elevados e erosao articular precoce.

Vacinação contra febre amarela em pacientes com diagnósticos de doenças reumáticas, em uso de imunossupressores

Yellow fever is endemic in some countries. The anti-yellow fever vaccine is the only effective means of protection but is contraindicated for immunocompromised patients. The aim of this paper was to report on a case series of rheumatological patients who were using immunosuppressors and were vaccinated against this disease. This was a retrospective study by means of a questionnaire applied to these patients, who were vaccinated 60 days before the investigation. Seventy patients of mean age 46 years were evaluated. Most of them were female (90%). There were cases of rheumatoid arthritis (54), systemic lupus erythematosus (11), spondyloarthropathy (5) and systemic sclerosis (2). The therapeutic schemes included methotrexate (42), corticosteroids (22), sulfasalazine (26), leflunomide (18), cyclophosphamide (3) and immunobiological agents (9). Sixteen patients (22.5%) reported some minor adverse effect. Among the eight patients using immunobiological agents, only one presented a mild adverse effect. Among these patients using immunosuppressors, adverse reactions were no more frequent than among immunocompetent individuals. This is the first study on this topic.

Yellow fever revaccination during infliximab therapy

Yellow fever vaccinations in patients receiving immunosuppressive therapy have been shown to be contraindicated due to the increased risk of viscerotropic disease in nonimmunocompetent patients (1). Biologic therapy such as anti–tumor necrosis factor (anti-TNF) has the capacity to block antibody development postvaccination, which is of concern to clinicians (2). Yellow fever vaccination is important in controlling this disease. Immunization of the native population and travelers is advisable in countries where this disease is endemic. Yellow fever vaccination uses a live attenuated virus (17-D strain) that induces low-grade viremia in 50% of the vaccinated people and elicits neutralizing antibody levels in 99% of all the vaccinated individuals (3,4). Recently an outbreak of yellow fever occurred in Brazil and, following a massive advertising campaign by the health authorities in the media, several patients receiving anti-TNF therapy were vaccinated without previously consulting their doctors. In Brazil, yellow fever vaccination is recommended every 10 years for those living in endemic areas. In view of this outbreak, there was a group of patients who had exceeded the 10-year revaccination period, and they demanded yellow fever vaccination in spite of receiving anti-TNF therapy. In this study we describe the clinical observations and laboratory findings of 17 rheumatoid arthritis patients receiving infliximab therapy while receiving the yellow fever vaccination and of paired controls.

The Wnt signaling pathway and rheumatoid arthritis.

The Wnt signaling pathways play a key role in cell renewal, and there are two such pathways. In patients with rheumatoid arthritis (RA), the synovial membrane expresses genes such as Wnt and Fz at higher levels than those observed in patients without RA. The Wnt proteins are glycoproteins that bind to receptors of the Fz family on the cell surface. The Wnt/Fz complex controls tissue formation during embryogenesis, as well as throughout the process of limb development and joint formation. Recent studies have suggested that this signaling pathway plays a role in the pathophysiology of RA. Greater knowledge of the role of the Wnt signaling pathway in RA could improve understanding of the differences in RA clinical presentation and prognosis. Further studies should also focus on Wnt family members as molecular targets in the treatment of RA.

Avaliação prospectiva da qualidade de vida em uma coorte de pacientes com artrite reumatoide inicial

INTRODUCTION Few studies have prospectively assessed the tools used to measure quality of life, both generic and specific, in patients with early rheumatoid arthritis (RA). OBJECTIVE The objective of this study was to characterize a population of patients with early RA (less than 12 months after symptom onset at the time of the diagnosis) prospectively followed for the pattern of responses to questionnaires addressing quality of life, the Health Assessment Questionnaire (HAQ) and Medical Outcomes Study SF-36 Health Survey (SF-36). PATIENTS AND METHODS Forty patients with early RA at the time of diagnosis, treated with a standard treatment regimen, were prospectively followed for 3 years. Demographic and clinical data were recorded, and HAQ and SF-36 questionnaires were applied at baseline and after 3, 6, 12, 18, 24, and 36 months. Paired Student t test and Wilcoxon test were used for comparisons (significance level of 5%). RESULTS The mean age was 45 years, with a prevalence of the female gender (90%). The average score of the initial HAQ was 1.89, with a progressive decline to 0.77 in the third year (P < 0.0001). Most domains of the SF-36 questionnaire presented significant improvement during the three years of follow-up, except for general health and vitality. CONCLUSION In this population of patients with early RA at the time of diagnosis, the results showed significant impact on quality of life at the time of diagnosis, as measured by HAQ and SF-36 questionnaires. The early treatment of RA seems to be associated with improved health-related quality of life reported by patients.

Infliximab Induces Increase in Triglyceride Levels in Psoriatic Arthritis Patients

Objectives. To evaluate lipid profile changes after anti-TNF therapy in patients with psoriatic arthritis (PsA). Methods. Fifteen PsA patients (eight polyarticular, four oligoarticular, two axial, and one mutilating) under infliximab were included. None had dyslipoproteinemia or previous statin use. Total cholesterol (TC) and its fractions, inflammatory markers, and prednisone use were evaluated. Results. The comparisons of lipid levels between baseline and after three months (3M) of anti-TNF therapy showed that there was a significant increase in mean triglycerides (117.8 ± 49.7 versus 140.1 ± 64.1 mg/dL, P = 0.028) and VLDL-c (23.6 ± 10.5 versus 28.4 ± 13.7 mg/dL, P = 0.019) levels. In contrast, there were no differences in the mean TC (P = 0.28), LDL-c (P = 0.42), and HDL-c (P = 0.26) levels. Analysis of the frequencies of each lipid alteration at baseline and at 3M were alike (P > 0.05). Positive correlations were found between VLDL-c and CRP (r = 0.647, P = 0.009) and between triglycerides and CRP (r = 0.604, P = 0.017) levels at 3M. ESR reduction was observed after 3M (P = 0.04). Mean prednisone dose remained stable at beginning and at 3M (P = 0.37). Conclusion. This study demonstrated that anti-TNF may increase TG and VLDL-c levels in PsA patients after three months.

Guidelines for the drug treatment of rheumatoid arthritis.

Description of evidence collection method A literature review of the scientific articles referenced in these guidelines was conducted with the MEDLINE database. The evidence search was based on real clinical scenarios, and the following keywords (MeSH terms) were used: Arthritis, Rheumatoid, Therapy (early OR late OR later OR time factors OR delay), Prognosis, Remission, Steroids, Anti-Inflammatory Agents, Non-Steroidal, NSAIDs, Diclofenac, Ibuprofen, Indomethacin, Piroxicam, COX-2, Celecoxib, Etoricoxib, Disease-modifying antirheumatic drug OR DMARD, Methotrexate, Gold sodium, Leflunomide, Sulfasalazine, Hydroxychloroquine, Tumor Necrosis Factor-alpha, Adalimumab, Certolizumab, Etanercept, Infliximab, Golimumab, Rituximab, Tocilizumab and Abatacept. Grades of recommendation and strength of evidence A: Most consistent experimental and observational studies. B: Less consistent experimental and observational studies. C: Case reports (uncontrolled studies). D. Opinion that is not substantiated by critical evaluation, based on consensus, physiological studies or animal models. Objective These guidelines aim to provide recommendations for the treatment of rheumatoid arthritis in Brazil. Although North American and European guidelines for the treatment of rheumatoid arthritis have been recently published, it is important to review the subject with regard to specific aspects of Brazilian reality. Thus, the ultimate purpose of the establishment of consensus guidelines for the treatment of rheumatoid arthritis in Brazil is to provide an orientation and foundation for Brazilian rheumatologists with evidence from scientific studies and the experience of a committee of experts on the subject. Thus, therapeutic approaches to rheumatoid arthritis within the Brazilian socioeconomic context will be standardized, while physician autonomy will be maintained with regard to the indication/ selection of available treatment options. As knowledge in this scientific field progresses rapidly, we suggest biannual updates to these guidelines.

Laboratory characteristics of a cohort of patients with early rheumatoid arthritis

INTRODUCTION/OBJECTIVE To characterize a population of patients with early rheumatoid arthritis (RA) according to laboratory aspects, comparing it with other similar cohorts. METHODS Data presented are part of a prospective incident cohort study that evaluated 65 patients with early RA, followed for 36 months from the diagnosis at Early Rheumatoid Arthritis Clinic of Hospital Universitário de Brasília (HUB). We recorded demographics, clinical, and laboratory data relevant to the cohort initial assessment, including red blood cells, evidence of inflammatory activity, and presence of autoantibodies (rheumatoid factor (RF)), cyclic citrullinated peptide antibodies (anti-CCP), and antivimentin citrullinated (anti-Sa). RESULTS There was a preponderance of female (86%) with mean age of 45.6 years. Twelve patients (18.46%) had laboratory diagnosis of anemia (hemoglobin < 12 g / dL). Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were above the reference value for 51 (78.46%) and 46 (70.76%) patients, respectively. Thirty-two patients (49.23%) were positive for at least one of the RF isotypes, and 28 patients (43.07%) were positive for IgA RF, 19 (29.23%) for IgG, and 32 ( 49.23%) for IgM RF, respectively; 34 patients (52.30%) were positive for at least one of the techniques used in investigation of anti-CCP (CCP2, or CCP3, or CCP3.1), while 9 (13,85%) were positive for anti-Sa. CONCLUSIONS The laboratory characteristics of patients enrolled in this Brazilian cohort are similar in many respects to those of North-American, European, and Latin-American cohorts previously published.

Frequency of sexual dysfunction in women with rheumatic diseases.

OBJECTIVE To assess the prevalence of sexual dysfunction in women followed up at the Rheumatology Outpatient Clinic of the Hospital Universitário de Brasília and of the Hospital das Clínicas da Universidade de São Paulo with the following rheumatic diseases: systemic lupus erythematosus; rheumatoid arthritis; systemic sclerosis; antiphospholipid antibody syndrome; and fibromyalgia. METHODS The Female Sexual Function Index (FSfi), obtained by applying a 19-item questionnaire that assesses six domains (sexual desire, arousal, vaginal lubrication, orgasm, sexual satisfaction and pain), was used. RESULTS This study assessed 163 patients. The mean age was 40.4 years. The prevalence of sexual dysfunction was 18.4%, but 24.2% of the patients reported no sexual activity over the past 4 weeks. Patients with fibromyalgia and systemic sclerosis had the highest sexual dysfunction index (33%). Excluding patients with no sexual activity, the sexual dysfunction rate reaches 24.2%. CONCLUSION The prevalence of sexual dysfunction found in this study was lower than that reported in the literature. However, 24.2% of the patients interviewed reported no sexual activity over the past 4 weeks, which might have contributed to the low sexual dysfunction index found.
