Systemic lupus erythematosus (SLE) is associated with dyslipidemia, atherosclerosis, and cardiovascular disease. In this study, we investigated the presence of dyslipidemia in Brazilian SLE patients by evaluating their lipid profile and immune status, including the production of autoantibodies and cytokines involved in atherogenesis. Ninety-four female SLE patients participated in this study and, based on their lipid profile, were classified as dyslipidemic or not. All were tested for antinuclear antibodies (ANAs), antiphospholipid antibodies, and autoantibodies to extractable nuclear antigens and double-stranded DNA. Serum levels of apolipoproteins A and B, C3, C4, and C-reactive protein were measured, as well as serum levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α, and IL-10. Lupus activity was scored according to the Systemic Lupus Erythematosus Disease Activity Index 2000. Sixty-nine patients (73.4%) had dyslipidemia, and the remaining 25 patients (26.6%) were non-dyslipidemic. Lupus activity was correlated with non-high-density lipoprotein cholesterol and triglyceride (TG) levels (non-HDL-C, r = 0.34 and p = 0.0043 and r = 0.46 and p < 0.0001, respectively). Atherogenic indexes apolipoprotein B/apolipoprotein A and TG:HDL-C ratios were higher in dyslipidemic women, and TG:HDL was correlated with disease activity (r = 0.40, p = 0.0007). IL-6, TNF-α, and IL-10 levels were similar between groups; however, a positive correlation between IL-6 and CRP levels was only observed in the group with dyslipidemia (r = 0.55, p < 0.0001). Female Brazilian SLE patients present a high prevalence of dyslipidemia and exhibit a higher risk of cardiovascular diseases as compared with female SLE patients without dyslipidemia and healthy individuals.

Our results suggest that neither prolactin nor ferritin is involved with the extra-hepatic manifestation of autoimmunity observed in HCV carriers.

The aim of this study was to evaluate the effects of Passiflora edulis f. flavicarpa Degener (yellow passion) juice on the lipid profile and oxidative stress status of Wistar rats. Adult male Wistar rats were divided in two groups (n = 8 animals per group): the control group, which received water, and the treated group, which was given P. edulis juice (1,000 mg/kg). Both groups received by gavage treatment twice a day for 28 days. The treated group showed an increased high-density lipoproteincholesterol level and decreased low-density lipoprotein-cholesterol and free fatty acid levels compared with the control group. Levels of triglycerides and and very low-density lipoprotein-cholesterol, superoxide dismutase activity, and total glutathione concentration were not statistically different between the two groups, but the thiobarbituric acid-reactive substances concentration (indicating lipid peroxidation) decreased in the treated group. These findings suggests that P. edulis juice in the experimental conditions used showed beneficial effects on lipid profile and improved lipid peroxidation in Wistar rats.

Jaccoud's arthropathy (JA) is a condition characterized clinically by 'reversible' joint deformities along with an absence of articular erosions on a plain radiograph. The main clinical entity associated with JA is systemic lupus erythematosus (SLE) with a prevalence of around 5 %. The aim of the present study was to compare the inflammatory markers including cytokine levels in blood of SLE patients with and without JA. Patients with diagnosis of SLE as defined by ACR criteria were screened and divided in two groups, one with JA and one control group without JA. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), complement C3 and C4 levels antinuclear antibodies (ANA), anti-dsDNA antibodies and serum levels of IL-2, IL-6, IL-10, IL-21, IL-22 and TNF-α were determined in all patients. Eighty female patients with SLE, 18 (22.5 %) with JA and 62 (77.5 %) without JA, were included in this study. JA patients had higher disease duration (p = 0.008), ESR (p < 0.001), CRP level (p = 0.002), ANA titer (p < 0.001) and dsDNA antibody level (p = 0.009). The serum levels of IL-2, IL-10, IL-21, IL-22 and TNF-α were not significantly different between the two groups (p > 0.05), but the level of IL-6 was higher in JA group (p < 0.001). The serum level of IL-6 might have a correlation with JA secondary to SLE.

ResumoEste artigo objetiva analisar trabalhos publicados sobre o modelo UTAUT nos anais dos três principais eventos brasileiros da área de Gestão de Tecnologia da Informação (CONTECSI, ENANPAD e ENADI), no período de 2011 a 2015. Pretende contribuir para um maior aprofundamento acerca da compreensão, por meio da teoria, da intenção comportamental no sentido da aceitação e uso de tecnologia da informação (TI), especialmente em um contexto cujo impacto da TI na vida das pessoas é crescente e dinâmico. Foi realizada a indexação dos anais dos três eventos citados, no período proposto, através do software Copernic Desktop Search (versão 5.1.0), realizando, posteriormente, uma filtragem pelo termo "utaut". Os resultados evidenciam que a produção de artigos sobre UTAUT no Brasil nas referidas condições aponta para uma maior utilização nas áreas de educação e comércio, apresentando, ainda, combinação com outras teorias e modelos como forma de atender os objetivos propostos pelos autores. (CONTECSI, ENANPAD and ENADI) Palavras-chave: Adoção de Tecnologia da Informação; UTAUT; produção científica. Abstract This paper aims to analyze published works about the UTAUT model in the annals of the three main Brazilian events in the area of Information Technology Management

Anti-neutrophil cytoplasmic antibodies (ANCA) are autoantibodies directed to intracellular components of neutrophils and are present in several vasculitic syndromes. Recently, these autoantibodies have been described in other autoimmune disorders as well as in infectious diseases such as tuberculosis (TB). As there are some clinical similarities between TB and granulomatosis with polyangiitis, we searched for ANCA in a group of patients with proven TB. Patients with TB confirmed by chest X-ray and sputum bacilloscopy either before or within 30 days after beginning treatment were included in this study. Anti-MPO and anti-PR3 antibodies were studied using well-standardized ELISA kits (INOVA Diagnostics, Inc.). ANCA were also investigated by indirect immunofluorescence (IIF). Fifty TB patients (26 females, mean age 47.34 ± 17 years) were enrolled in the present study. No patient tested positive for ANCA by IIF, or anti-MPO or anti-PR3 antibodies by ELISA. Although previous studies have shown the presence of ANCA in some infectious diseases, the findings of the present study demonstrated the absence of such antibodies in TB. The discrepancy in the prevalence of ANCA in TB among different studies may be attributed to methodological factors and/or the genetic background of the studied populations.

We investigated in Brazilian women with SLE the prevalence and levels of high avidity (HA) dsDNA antibodies and tested their correlation with lupus activity and biomarkers of renal disease. We also compared these correlations to those observed with total dsDNA antibodies and antibodies against nucleosome (ANuA). Autoantibodies were detected by ELISA, while C3 and C4 levels were determined by nephelometry. Urine protein/creatinine ratio was determined, and lupus activity was measured by SLEDAI-2K. The prevalence of total and HA dsDNA antibodies was similar to but lower than that verified for ANuA. The levels of the three types of antibodies were correlated, but the correlation was more significant between HA dsDNA antibodies and ANuA. High avidity dsDNA antibodies correlated positively with ESR and SLEDAI and inversely with C3 and C4. Similar correlations were observed for ANuA levels, whereas total dsDNA antibodies only correlated with SLEDAI and C3. The levels of HA dsDNA antibodies were higher in patients with proteinuria, but their levels of total dsDNA antibodies and ANuA were unaltered. High avidity dsDNA antibodies can be found in high prevalence in Brazilian women with SLE and are important biomarkers of active disease and kidney dysfunction.
