Effect of the bilateral hip bone density measurement on clinical practice in elderly subjects

Objectives: The aim of this study was to determine whether the addition of the measurement of bilateral hip bone mineral density (BMD) has an impact on indications for osteoporosis (OP) treatment in community-dwelling elderly individuals, based on criteria from the National Osteoporosis Foundation (NOF). Methods: In total, 605 consecutive community-dwelling elderly individuals who were 65 years and older were evaluated. Dual energy X-ray absorptiometry was used to determine the lowest T-score in the lumbar spine + unilateral hip, the bilateral hips, and the lumbar spine + bilateral hips. Risk factors associated with the lowest T-score in these three conditions were applied to indicate treatment in accordance with NOF criteria. McNemar`s test was used to assess the difference of adding bilateral hip BMD measurements. Results: There was a significant difference in the frequency of pharmacological indication using NOF criteria together with the lowest T-score for the three tests (72.8% for lumbar spine + bilateral hips and 71.2% for lumbar spine + unilateral hip; p=0.002). A higher frequency of treatment indication was also observed for lumbar spine + unilateral hip (71.2%) compared to bilateral hips (61.1%) (p<0.001). The discrepancies in treatment appeared to be more evident in women when analyzed by gender distribution. Conclusion: Our finding supports the theory that evaluation of the bilateral hips with the lumbar spine seems to be more sensitive measure for identifying patients with an osteoporosis treatment indication. Furthermore, despite the well-known artifact in the lumbar spine, this site should not be excluded when determining the indication for OP treatment in elderly people. (C) 2009 Elsevier Ireland Ltd.

Juvenile systemic lupus erythematosus and dermatomyositis associated with urticarial vasculitis syndrome: a unique presentation

To report a case of triple association of juvenile systemic lupus erythematosus (SLE), juvenile dermatomyositis and urticarial vasculitis as well as a review of the relevant literature. A 12-year-old male patient diagnosed with overlap syndrome between SLE and juvenile dermatomyositis since 2004 evolved with erythematous plaques, which were compatible with an urticarial rash. Clinical, laboratory and histopathological findings indicated a diagnosis of urticarial vasculitis. The patient previously had a C1q deficiency. Using the established treatment with methylprednisolone (1 g/day for 3 days), increasing doses of deflazacort and introduction of a dapsone, as well as mycophenolate mofetil regimen, with the suspension of azathioprine resulted in complete resolution of skin lesions. Urticarial vasculitis can present in various diseases. In SLE, presentation of urticarial vasculitis in children is rarely found. The triple association of juvenile-onset SLE, juvenile dermatomyositis and urticarial vasculitis is unusual, and this is the first case described in literature.Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ) [300559/2009-7, 300665/2009-1]Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq)Wilhelm Agricola Federico FoundationWilhelm Agricola Federico Foundatio

Fluctuation of Anti-Endothelial Cell Antibody Titers in Mixed Connective Tissue Disease

Background: Antibodies directed against endothelial cell surface antigens have been described in many disorders and have been associated with disease activity. Since the most prominent histopathologic feature in mixed connective tissue disease (MCTD) is the widespread and unique proliferative vascular lesion, our aim was to evaluate the frequency of anti-endothelial cell antibodies (AECA) in this condition. Objectives: To evaluate the frequency of AECA in this disease and assess its clinical and laboratory associations. Methods: Seventy-three sera from 35 patients with MCTD (Kasukawa's criteria), collected during a 7 year period, were tested for immunoglobulins G and M (IgG and IgM) AECA by cellular ELISA, using HUVEC (human umbilical vein endothelial cells). Sera from 37 patients with systemic lupus erythematosus (SLE), 22 with systemic sclerosis (SSc) and 36 sera from normal healthy individuals were used as controls. A cellular ELISA using HeLa cells was also performed as a laboratory control method. Results: IgG-AECA was detected in 77% of MCTD patients, 54% of SLE patients, 36% of SSc patients and 6% of normal controls. In MCTD, IgG-AECA was associated with vasculitic manifestations, disease activity and lymphopenia, and was also a predictor of constant disease activity. Immunosuppressive drugs were shown to reduce IgG-AECA titers. Since antibodies directed to HeLa cell surface were negative, AECA was apparently unrelated to common epitopes present on epithelial cell lines. Conclusions: AECA are present in a large proportion of patients with MCTD and these antibodies decrease after immunosuppressive treatment.

Autoimmune disease and multiple autoantibodies in 42 patients with RASopathies

The association of RASopathies [Noonan syndrome (NS) and Noonan-related syndromes] and autoimmune disorders has been reported sporadically. However, a concomitant evaluation of autoimmune diseases and an assessment of multiple autoantibodies in a large population of patients with molecularly confirmed RASopathy have not been performed. The clinical and laboratory features were analyzed in 42 RASopathy patients, the majority of whom had NS and five individuals had Noonan-related disorders. The following autoantibodies were measured: Anti-nuclear antibodies, anti-double stranded DNA, anti-SS-A/Ro, anti-SS-B/La, anti-Sm, anti-RNP, anti-Scl-70, anti-Jo-1, anti-ribosomal P, IgG and IgM anticardiolipin (aCL), thyroid, anti-smooth muscle, anti-endomysial (AE), anti-liver cytosolic protein type 1 (LC1), anti-parietal cell (APC), anti-mitochondrial (AM) antibodies, anti-liver-kidney microsome type 1 antibodies (LKM-1), and lupus anticoagulant. Six patients (14%) fulfilled the clinical criteria for autoimmune diseases [systemic lupus erythematous, polyendocrinopathy (autoimmune thyroiditis and celiac disease), primary antiphospholipid syndrome (PAPS), autoimmune hepatitis, vitiligo, and autoimmune thyroiditis]. Autoimmune antibodies were observed in 52% of the patients. Remarkably, three (7%) of the patients had specific gastrointestinal and liver autoantibodies without clinical findings. Autoimmune diseases and autoantibodies were frequently present in patients with RASopathies. Until a final conclusion of the real incidence of autoimmunity in Rasopathy is drawn, the physicians should be alerted to the possibility of this association and the need for a fast diagnosis, proper referral to a specialist and ultimately, adequate treatment.

Brazilian biologic registry: BiobadaBrasil implementation process and preliminary results

OBJETIVOS: O presente estudo teve por objetivo descrever o processo de implementação de um registro nacional em um país em desenvolvimento (Brasil) e relatar os principais resultados preliminares do registro BiobadaBrasil. MATERAL E MÉTODOS: Através de um acordo com a PANLAR, o protocolo Biobadaser foi utilizado como modelo para a implementação de um novo registro no nosso país. Durante os dois primeiros anos desse esforço, o protocolo original foi adaptado, traduzido e apresentado a todos os reumatologistas brasileiros. Durante dez meses, dados de 1.037 pacientes (750 tratados com biológicos e 287 controles) de 15 centros foram coletados. RESULTADOS: A maioria dos pacientes tinha artrite reumatoide (AR) (n = 723). Infliximabe foi o agente anti-TNF mais usado, e a exposição total a biológicos foi 2.101 pacientes-ano. A razão mais comum para suspensão da droga foi ineficiência ou perda de efetividade (50%), e 30% dos pacientes interromperam o tratamento devido a eventos adversos. Três casos de tuberculose foram observados no grupo biológico, representando maior incidência do que aquela da população brasileira geral. Infecções foram observadas em 23% dos pacientes do grupo biológico, sendo o trato respiratório superior o local mais comumente afetado. Apenas um caso de hanseníase tuberculoide foi observado. Nenhuma morte nem malignidade atribuível ao efeito dos medicamentos foi observada até fevereiro de 2010. CONCLUSÕES: A implementação do registro foi bem sucedida. Embora recente, o registro BiobadaBrasil já forneceu importantes dados.OBJECTIVES: The present study aimed at describing the implementation process of a national registry in a developing country (Brazil) and at reporting the main preliminary results of the BiobadaBrasil registry. MATERIAL AND METHODS: Through a PANLAR agreement, the Biobadaser protocol was used as a model for implementing the new registry in our country. During the first two years of this effort, the original protocol was adapted, translated, and presented to all Brazilian rheumatologists. For ten months, data of 1,037 patients (750 subjects treated with biological drugs and 287 control subjects) from 15 centers were collected. RESULTS: Most patients had rheumatoid arthritis (RA) (n = 723). Infliximab was the most frequently used anti-TNF agent, and the total exposure to biologic drugs was 2,101 patient-years. The most common reason for interrupting drug use was lack or loss of efficacy (50%), while 30% withdrew from the treatment arm due to adverse events. Three cases of tuberculosis were observed in the biologic group, with an incidence higher than that of the general Brazilian population. Infections were observed in 23% of the biologic group, and the upper respiratory tract was the most commonly affected site. Only one case of tuberculoid leprosy was observed. No deaths or malignancies attributed to drug effects were observed as of February 2010. CONCLUSIONS: The implementation of the BiobadaBrasil registry was successful, and, although recent, the registry has provided important data.Sociedade Brasileira de Reumatologi
