Antibodies Towards High-Density Lipoprotein Components in Patients with Psoriasis
Paiva-Lopes, MJ; Batuca, J; Gouveia, S; Alves, M; Papoila, AL; Delgado Alves, JPsoriasis is a chronic inflammatory immune disorder associated with an increased risk of atherosclerosis. This increased risk is not fully understood. High-density lipoproteins (HDL) play an important role in the prevention of atherosclerosis and any factors that may hamper HDL function such as anti-HDL antibodies (aHDL) might be associated with an increased cardiovascular risk. We aimed to determine whether an...
ELISA methods comparison for the detection of auto-antibodies against apolipopr...
Frias, MA; Virzi, J; Batuca, J; Alves, JD, et al.BACKGROUND: Autoantibodies against apolipoprotein A1 (anti-apoA1 IgG) have emerged as an independent biomarker for cardiovascular disease and mortality. Across studies, different ELISA methods have been used to measure the level of circulating anti-apoA1 IgG which could lead to substantial result differences between assays. OBJECTIVES: To make a comparative study of available anti-apoA1 IgG detection methods an...

Antibodies against HDL Components in Ischaemic Stroke and Coronary Artery Disease
Batuca, J; Amaral, M; Favas, C; Justino, G; Papoila, A; Ames, P; Alves, JDQuantitative and qualitative defects of high-density lipoprotein (HDL) are important in atherogenesis. In this study, we investigated whether antibodies against HDL components had additional value to conventional cardiovascular risk factors for the diagnosis of ischaemic stroke (IS) and coronary artery disease (CAD). Cross-sectional study was conducted on 53 patients with IS, 51 with CAD and 55 healthy controls...
Extended-release niacin increases anti-apolipoprotein A-I antibodies that block...
Batuca, J; Amaral, M; Favas, C; Paula, F; Ames, P; Papoila, A; Alves, JDExtended-release niacin (ERN) is the most effective agent for increasing high-density lipoprotein-cholesterol (HDL-C). Having previously identified anti-HDL antibodies, we investigated whether ERN affected the antioxidant capacity of HDL and whether ERN was associated with the production of antibodies against HDL (aHDL) and apolipoprotein A-I (aApoA-I). METHODS: Twenty-one patients older than 18 years, with HDL...
Effect of efavirenz on high-density lipoprotein antioxidant properties in HIV-i...
Pereira, S; Batuca, J; Caixas, U; Branco, T; Delgado-Alves, J; Germano, I; Lampreia, F; Monteiro, EWHAT IS ALREADY KNOWN ABOUT THIS SUBJECT: * In previous work, we showed a long-term and concentration-dependent beneficial effect of the non-nucleoside reverse transcriptase inhibitor efavirenz (EFV) on high-density lipoproteins (HDL) in human immunodeficiency virus (HIV)-infected patients. * Furthermore, it has been suggested that instead of the current practice of only measuring HDL-chelesterol values, the ev...
