The aims of the present study were to report the frequency of metabolic syndrome in systemic lupus erythematosus (SLE); to verify differences in inflammatory biomarkers and oxidative stress in SLE patients with or without metabolic syndrome; and to assess which metabolic syndrome components are associated with oxidative stress and disease activity. The(More)
OBJECTIVE The aim of the present study was to assess oxidative stress and iron metabolism in systemic lupus erythematosus (SLE) patients with and without insulin resistance (IR). METHOD This study included 236 subjects (125 controls and 111 SLE patients). Patients with SLE were divided in two groups: with (n = 72) or without (n = 39) IR. RESULTS SLE(More)
OBJECTIVES To determine whether disease activity verified by laboratorial parameters is associated with a higher frequency of hypertension in patients with systemic lupus erythematosus (SLE) without renal impairment and to investigate factors that could influence this hypertension. METHOD This study included 102 controls, 70 patients with inactive SLE,(More)
OBJECTIVES Although vitamin D deficiency can change liver injury progression in patients with hepatitis C virus (HCV), the main molecular mechanisms involved are largely unknown. The first aim of this study was to evaluate the association between oxidative stress and hypovitaminosis D in patients with HCV. The second aim was to verify whether oxidative(More)
The aims of the present study were to evaluate biomarkers of oxidative and nitrosative stress in systemic lupus erythematosus (SLE) patients, in particular products of DNA/RNA oxidative damage and their correlation with disease activity. This study included 188 controls and 203 patients; 153 with inactive SLE (SLEDAI < 6) and 50 with active SLE (SLEDAI ≥ 6)(More)
Oxidative stress exerts an important role on the pathophysiological mechanisms of systemic lupus erythematosus (SLE). This study investigated oxidative stress in patients with SLE and its correlation with disease activity, corticosteroid therapy, and liver function biomarkers. The study included 58 patients with SLE and 105 healthy volunteers. Patients(More)
Metabolic syndrome (MS) is a multifactorial disease involving inflammatory activity and endothelial dysfunction. The aim of the present study was to evaluate the relationship between the changes in lipoperoxidation, in immunological and biochemical parameters and nitric oxide metabolite (NOx) levels in MS patients. Fifty patients with MS (4 males/46(More)
The T rare allele of +1444CT (rs1130864) polymorphism of C-reactive protein (CRP) has been associated with increased CRP levels in some inflammatory conditions, but its role on systemic lupus erythematosus (SLE) susceptibility and on CRP levels in SLE patients remains uncertain. The objective of the study was to evaluate the association between the(More)
