INTRODUÇÃO: O Lúpus Eritematoso Sistêmico (LES) se caracteriza por períodos de exacerbação e remissão clínica que frequentemente são acompanhados por alterações nos níveis séricos de anticorpos específicos, como o anti-dsDNA, que está presente em 40% dos casos, associado principalmente à atividade renal. Recentemente houve a descrição de duas subpopulações de anticorpos antilipoproteína lipase (anti-LPL) no LES: uma com e a outra sem atividade anti-dsDNA. A possível relação desse último grupo de anticorpos com a atividade inflamatória de doença ainda não foi analisada no LES. OBJETIVOS: Avaliar longitudinalmente a associação dos níveis séricos dos anticorpos anti-LPL com atividade do LES em pacientes com anti-dsDNA persistentemente negativo. PACIENTES E MÉTODOS: Cinco pacientes com LES com anti-dsDNA persistentemente negativo mensurado por ELISA e por imunofluorescência indireta em crithidia luciliae e altos títulos de anti-LPL por ELISA (> 5 desvios-padrão (DP) da média de 20 controles normais) foram selecionados e acompanhados longitudinalmente durante um período mínimo de dois anos. RESULTADOS: Caso 1: Homem, 24 anos com LES desde 2001 apresentou hemorragia alveolar, proteinúria, hipertensão arterial sistêmica...

Tendon rupture has rarely been described in patients with systemic lupus erythematosus. From observation of three cases of Jaccoud`s arthropathy with tendon rupture, and considering that this arthropathy is more related to an inflammatory process of the tendon sheath than to synovitis per se, the intention of this study was to review the cases of tendon rupture in patients with systemic lupus erythematosus, in the hope of determining the frequency of Jaccoud`s arthropathy associated with this complication. Systematic review using MEDLINE, Scielo and LILACS databases (1966 to 2009) and the following keywords: systemic lupus erythematosus, tendon rupture, Jaccoud`s arthropathy. Secondary references were additionally obtained. Additionally, three Brazilian systemic lupus erythematosus patients who developed tendon rupture are described. Only 40 articles obtained fulfilled the previously established criteria. They were all case reports; the number of cases reported was 52 which, together with the three cases presented herein add up to 55 cases. Forty-six patients were women aged between 19 and 71 years, with a mean age of 40.1 +/- 12.4 years, and the average duration of the disease was 10 years. The most frequently observed rupture sites were the patellar and Achilles` tendons. While almost all patients described were on various doses of corticosteroids...

Atherosclerosis is an inflammatory disease, leading to the formation of pro-inflammatory and pro-oxidative lipids that generate an immune response. Several antigens have been shown to activate the immune response and affect the development of atherogenesis. Systemic lupus erythematosus is an autoimmune and inflammatory disease strongly associated with premature development of atherosclerotic plaques. Modulation of the immune system could represent a useful approach to prevent and/or treat atherosclerosis. A vaccination-based approach might be a useful, effective tool in the modern arsenal of cardiovascular therapies and could be used on a large scale at a low cost. In non-systemic lupus erythematosus populations, vaccines against oxidized low-density lipoprotein, beta-2-glycoprotein I, heat shock proteins, lipoproteins, cholesterol, molecules involved in cholesterol metabolism, and other molecules (CD99, vascular endothelial growth factor-receptor, and interleukin-2) have been tested, with promising results. However, there are no studies of vaccination against atherosclerosis in systemic lupus erythematosus.

OBJETIVO: Avaliar a variabilidade da densidade mineral óssea em pacientes com lúpus eritematoso sistêmico, antes do início e após 30 e 60 dias do início de glicocorticoterapia. MATERIAIS E MÉTODOS: Estudo efetuado em 15 mulheres em pré-menopausa com lúpus eritematoso sistêmico encaminhadas para realização de densitometria óssea e que fariam uso de corticosteróides logo após o exame. RESULTADOS: Demonstrou- se que a densidade mineral óssea, em g/cm², na coluna lombar reduziu-se significativamente entre a análise prévia ao uso e a análise em 60 dias de uso da medicação, mas no colo femoral não houve diferença significativa. CONCLUSÃO: Concluiu-se que o uso de corticoterapia em pacientes com lúpus eritematoso sistêmico, em curto prazo, reduz significativamente a densidade mineral óssea na coluna lombar, não somente em longo prazo como descrito anteriormente por outros autores.; OBJECTIVE: To evaluate the bone mineral density variability in patients with systemic lupus erythematosus, before the beginning and at 30 and 60 days from the beginning of glucocorticoid therapy. MATERIALS AND METHODS: Fifteen premenopausal women with systemic lupus erythematosus were referred for bone densitometry before being submitted to glucocorticoid therapy. RESULTS: It was demonstrated that the bone mineral density in g/cm² in the lumbar spine presented a significant decrease in the span between the first analysis previously to the beginning of the glucocorticoid therapy and the third analysis after 60 days under therapy. On the other hand no significant difference was found in the femoral neck. CONCLUSION: The authors conclude that...

OBJECTIVE: To determine the serum levels of interferon alpha in childhood-onset systemic lupus erythematosus patients, their first-degree relatives and healthy controls and to evaluate the associations between serum interferon alpha and disease activity, laboratory findings and treatment features. METHODS: We screened consecutive childhood-onset systemic lupus erythematosus patients in a longitudinal cohort at the pediatric rheumatology unit of the State University of Campinas between 2009 and 2010. All patients demonstrated disease onset before the age of 16. Disease status was assessed according to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). Interferon alpha levels were measured using an enzyme-linked immunoabsorbent assay. RESULTS: We included 57 childhood-onset systemic lupus erythematosus patients (mean age 17.33 +/- 4.50), 64 first-degree relatives (mean age 39.95 +/- 5.66), and 57 healthy (mean age 19.30 +/- 4.97) controls. Serum interferon alpha levels were significantly increased in childhood-onset systemic lupus erythematosus patients compared to their first-degree relatives and healthy controls. Interferon alpha levels were significantly increased in patients with positive dsDNA antibodies...

Objective: To define the pattern of disease expression and to gain better understanding in patients with juvenile onset systemic lupus erythematosus (SLE) in Portugal. Methods: The features of unselected patients with systemic lupus erythematosus who had disease onset before the age of 18 years were retrospectively analysed in three Portuguese centres with Pediatric Rheumatology Clinic over a 24-year period (1987-2011). Demographic, clinical and laboratory manifestations, therapy and outcome were assessed. Results: A cohort of 56 patients with a mean age at di- sease onset of 12.6±4.04 years (mean±1SD) (range, 1.0- -17.0 years) and a mean period of follow-up of 5.5±5.4 years. Forty six (82.1%) patients were female. The most common disease manifestations were musculoskeletal (87.5%), mucocutaneous (80.3%) and haematological abnormalities (75%). Lupus nephritis was diagnosed in 46.4% of patients and consisted of glomerular ne - phritis in all cases. Neuropsychiatric manifestations occurred in 21.4% but severe central nervous system complications were uncommon, as brain infarcts and organic brain syndrome in 4 (7.1%) patients. Antinuclear antibodies and anti-double stranded DNA were positive in most patients in (98.2% and 71.4% respec- tively)...

The aim of the present study was to identify the risk factors for ovarian failure in patients with systemic lupus erythematosus. Seventy-one women aged 17 to 45 years with systemic lupus erythematosus were studied. Patients were interviewed and their medical records reviewed. Demographic characteristics, clinical and serologic profiles, and menstrual and obstetric histories were recorded. Disease activity was measured by the systemic lupus erythematosus disease activity index. Serum FSH, LH, estradiol, progesterone, TSH, prolactin, and antimicrosomal and antithyroglobulin antibodies were measured. Patients who developed ovarian failure were compared to those who did not. Ovarian failure occurred in 11 patients (15.5%) and nine had premature menopause (11.3%). Cyclophosphamide administration and older patient age were found to be associated with ovarian failure. The cumulative cyclophosphamide dose was significantly higher in patients with ovarian failure than in those without this condition (18.9 vs 9.1 g; P = 0.04). The relative risk for ovarian failure in patients with cumulative cyclophosphamide dose higher than 10 g was 3.2. TSH levels were high in 100% of patients with ovarian failure who had received pulse cyclophosphamide. Ovarian failure...

OBJECTIVE: The goal of the present study was to estimate the risk ratio of herpes zoster among systemic lupus erythematosus patients after disease onset compared with a cohort of patients without systemic lupus erythematosus over a three-year period. METHODS: A nationwide population-based cohort study using the National Health Insurance Research Database identified 10,337 new cases of systemic lupus erythematosus as the study cohort. In addition, 62,022 patients without systemic lupus erythematosus, who were matched for age, gender, and date of systemic lupus erythematosus diagnosis, were used as the comparison cohort. These cohorts were followed-up for three years. A Cox proportional hazard regression was performed to estimate the risk ratio of herpes zoster, with adjustments for age, gender, level of insurance, urbanization level, geographic region, comorbid medical conditions, average daily dosage of corticosteroids, and the use of immune-modulation agents. RESULTS: Compared to patients without systemic lupus erythematosus, the crude risk ratio and adjusted risk ratio of herpes zoster among systemic lupus erythematosus patients were 7.37 (95% confidence interval 6.75-8.04) and 2.45 (95% confidence interval 1.77-3.40), respectively.

OBJECTIVES: Hydroxychloroquine is an antimalarial agent that has been used in systemic lupus erythematosus and rheumatoid arthritis treatment for many years. Recently, novel mechanisms of action have been proposed, thereby broadening the therapeutic perspective of this medication. The purpose of this study was to evaluate the immunomodulatory activity of hydroxychloroquine in T helper 17 (Th17) cytokines in healthy individuals and patients. METHODS: Eighteen female patients with systemic lupus erythematosus (mean age 39.0±12.9 years) and 13 female patients with rheumatoid arthritis (mean age 51.5±7.7 years) were recruited from Universidade Federal de Pernambuco-Brazil. The patients were included after fulfilling four classification criteria for systemic lupus erythematosus or rheumatoid arthritis from the American College of Rheumatology. After being stimulated with phorbol 12-myristate 13-acetate and ionomycin in the absence or presence of different concentrations of hydroxychloroquine, the interleukin 6, 17 and 22 levels were quantified with an enzyme-linked immunosorbent assay in culture supernatants of peripheral blood mononuclear cells from healthy individuals and patients. RESULTS: We demonstrated that in peripheral blood mononuclear cells from healthy volunteers and in systemic lupus erythematosus and rheumatoid arthritis patients...

OBJECTIVES: To determine the serum interleukin-17 (IL-17) levels in childhood-onset systemic lupus erythematosus patients and to evaluate the association between IL-17 and clinical manifestations, disease activity, laboratory findings and treatment. METHODS: We included 67 consecutive childhood-onset systemic lupus erythematosus patients [61 women; median age 18 years (range 11-31)], 55 first-degree relatives [50 women; median age 40 years (range 29-52)] and 47 age- and sex-matched healthy controls [42 women; median age 19 years (range 6-30)]. The childhood-onset systemic lupus erythematosus patients were assessed for clinical and laboratory systemic lupus erythematosus manifestations, disease activity [Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)], cumulative damage [Systemic Lupus International Collaborating Clinics/American College of Rheumatology (ACR) Damage Index] and current drug use. Serum IL-17 levels were measured by an enzyme-linked immunosorbent assay using commercial kits. RESULTS: The median serum IL-17 level was 36.3 (range 17.36-105.92) pg/mL in childhood-onset systemic lupus erythematosus patients and 29.47 (15.16-62.17) pg/mL in healthy controls (p=0.009). We observed an association between serum IL-17 levels and active nephritis (p=0.01) and migraines (p=0.03). Serum IL-17 levels were not associated with disease activity (p=0.32)...

OBJECTIVE: The aim of this study was to assess the IgE serum levels in juvenile systemic lupus erythematosus patients and to evaluate possible associations with clinical and laboratory features, disease activity and tissue damage. METHODS: The IgE serum concentrations in 69 consecutive juvenile systemic lupus erythematosus patients were determined by nephelometry. IgG, IgM and IgA concentrations were measured by immunoturbidimetry. All patients were negative for intestinal parasites. Statistical analysis methods included the Mann-Whitney, chi-square and Fisher's exact tests, as well as the Spearman rank correlation coefficient. RESULTS: Increased IgE concentrations above 100 IU/mL were observed in 31/69 (45%) juvenile systemic lupus erythematosus patients. The mean IgE concentration was 442.0 +/- 163.4 IU/ml (range 3.5- 9936.0 IU/ml). Fifteen of the 69 patients had atopic disease, nine patients had severe sepsis and 56 patients presented with nephritis. The mean IgE level in 54 juvenile systemic lupus erythematosus patients without atopic manifestations was 271.6 +/- 699.5 IU/ml, and only nine of the 31 (29%) patients with high IgE levels had atopic disease. The IgE levels did not statistically differ with respect to the presence of atopic disease...

OBJECTIVE: To analyze the frequency of human leukocyte antigens class II-DR in children and adolescents with systemic lupus erythematosus. PATIENTS AND METHODS: Fifty-fiveBrazilian systemic lupus erythematosus children and adolescents and 308 healthy individuals were studied. Gender, race, and age of onset of systemic lupus erythematosus were recorded. The human leukocyte antigens typing of class II-DR was carried out by polymerase chain reaction amplification with sequence-specific primers (PCR-SSP). Data were analyzed statistically using the chi square test with Yates' correction, Fisher's exact test, and Bonferroni's correction. RESULTS: Human leukocyte antigen-DR 15 was the most frequently detected antigen in this group of children and adolescents, and it also occurred more frequently in the female group, in children with onset of systemic lupus erythematosus between 0 and 9 years and between 10 to 14 years, and in the Black race group, but these associations were not statistically significants. CONCLUSION: In this group of children and adolescents with a high degree of racial admixture, we could not verify a significant association between human leukocyte antigens class II-DR and systemic lupus erythematosus.

OBJETIVO: Analisar a freqüência dos antígenos de histocompatibilidade leucocitária de classe II-DR em crianças e adolescentes com o lúpus eritematoso sistêmico. PACIENTES E MÉTODOS: Cinqüenta e cinco crianças e adolescentes lúpicos brasileiros e 308 indivíduos sadios foram estudados. Os sexos, os grupos étnicos e as idades de início da doença foram anotados. A tipagem de histocompatibilidade leucocitária de classe II-DR foi realizada pela reação de polimerase em cadeia com amplificação de sondas de seqüência específica (PCR-SSP). Na análise estatística foram utilizados o teste de qui-quadrado com correção de Yates, o teste exato de Fisher e a correção de Bonferroni. RESULTADOS: A histocompatibilidade leucocitária-DR15 foi a mais freqüente neste grupo de crianças e adolescentes, sendo também mais freqüente nas mulheres, nas crianças com idade de início da doença entre zero e nove anos e entre 10 e 14 anos e nas crianças de raça negra, mas estas correlações não foram estatisticamente significativas. CONCLUSÃO: Neste grupo de crianças e adolescentes com alto grau de miscigenação não pudemos observar associação significativa entre os antígenos de histocompatibilidade leucocitária de classe II-DR e o lúpus eritematoso sistêmico.; OBJECTIVE: To analyze the frequency of human leukocyte antigens class II-DR in children and adolescents with systemic lupus erythematosus. PATIENTS AND METHODS: Fifty-fiveBrazilian systemic lupus erythematosus children and adolescents and 308 healthy individuals were studied. Gender...

OBJETIVO: Investigara freqüência e o comportamento dos anticorpos antifosfolípides em 57 crianças e adolescentes com lúpus eritematoso sistêmico. MÉTODOS: A técnica laboratorial para a pesquisa do anticorpo anticardiolipina foi ELISA e para a pesquisa do anticorpo anticoagulante lúpico foram seguidas as recomendações internacionais. A pesquisa dos anticorpos antifosfolípides foi realizada em soros estocados (média de 5,3 amostras por paciente durante o período de seguimento de em média 3 anos e 7 meses) e em soros coletados no período de janeiro de 1997 à novembro de 1998 (média de 2,5 amostras por paciente em um período de dois anos). RESULTADOS: A freqüência dos anticorpos antifosfolípides (anticorpo anticardiolipina e anticoagulante lúpico) foi semelhante nos soros coletados prospectivamente e nos soros estocados (estudo retrospectivo): 63,2% e 75,4% respectivamente. A positividade destes anticorpos flutuou durante o seguimento e não esteve associado a nenhum parâmetro clínico e laboratorial do lúpus eritematoso sistêmico, incluindo auto-anticorpos e também atividade e/ou gravidade da doença. CONCLUSÕES: A freqüência dos anticorpos antifosfolípides em crianças e adolescentes com lúpus eritematoso sistêmico foi semelhante à observada em adultos. A positividade dos anticorpos flutuou durante o seguimento dos pacientes e não foi evidenciada associação com parâmetros clínicos e/ou laboratoriais da doença.; OBJECTIVE: To investigate the frequencies and behavior of antiphospholipid antibodies in 57 children and adolescents with systemic lupus erythematosus. METHODS: Anticardiolipin antibodies were investigated by ELISA and lupus anticoagulant antibodies by the international tests recommended. The antiphospholipid antibodies analyses were performed in frozen samples (mean of 5.3 samples per patient obtained during a mean follow-up period of 3 years and 7 months) and on blood samples collected between January 1997 and November 1998 (mean of 2.5 samples per patient during a 2-year follow-up period). RESULTS: The frequencies of antiphospholipid antibodies (anticardiolipin and lupus anticoagulant) were similar in the samples collected prospectively and in the frozen samples (retrospective study): 63.2% and 75.4% respectively. Positivity for these antibodies fluctuated during the follow-up period and was not associated with any clinical or laboratory parameters of lupus erythematosus...
