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 rs1130864 CRP polymorphism with SLE susceptibility, disease activity, and CRP levels in SLE Brazilian patients. The study enrolled 176 SLE patients and 137 controls...

Autoantibodies against the major acute-phase reactant C-reactive protein (CRP) are frequently found in patients with lupus nephritis. Further defining the autoimmune epitopes on CRP may not only improve patient stratification but also, hint at mechanisms of CRP action. Herein, we show that amino acids 35-47 constitute the major epitope recognized by anti-CRP autoantibodies in patients with lupus nephritis. Notably, the presence of autoantibodies against amino acids 35-47 associated with more severe renal damage and predicted worse outcome...

A 41-year-old female patient was admitted because of febrile jaundice and acute liver failure. The quick and the bilirubin were 21 % and 258 µmol/l, and there was hepatic encephalopathy I°. AST and AP had a maximum of 612 and 215 U/l. Despite a strong left shift in the differential, the CRP had a maximum of 15 mg/l. Because of an atypically presenting systemic lupus erythematosus, she had been treated with Azathioprine, steroids and Tocilizumab until 12 days before admission. The diagnostic workup revealed CMV hepatitis and necrotizing hepatopathy, which was interpreted as toxic hepatitis...

Objectives Childhood-onset systemic lupus erythematosus (cSLE) is a multisystemic autoimmune disease characterized by inflammatory organ damage by means of vasculitis. Pentraxin-3 (PTX3) is expressed locally at the sites of inflammatory processes, predominantly from endothelial cells. In adult studies, PTX3 has shown to be an indicator of active vasculitis both in large-vessel and small-vessel vasculitides, as well as in SLE. Moreover, in SLE it has found to be correlated with disease activity, and with some of the clinical manifestations and laboratory parameters...

Nova Scotia Duck Tolling Retrievers (NSDTRs) are a dog breed often affected by immune-mediated rheumatic disease (IMRD), a disorder characterised by chronic stiffness and joint pain. Most, but not all, dogs with IMRD, have antinuclear antibodies (ANA), which are also commonly present in the autoimmune disease systemic lupus erythematosus (SLE). The clinical and diagnostic findings of IMRD indicate that it is an SLE-related disorder. C-reactive protein (CRP), an acute phase protein, is a quantitative marker of inflammation for many diseases and is used for diagnosing and monitoring systemic inflammation in both humans and dogs...

OBJECTIVE: The interleukin 17 (IL-17) cytokine family is involved in a number of chronic inflammatory diseases. In spite of contradictory findings and a lack of causality in clinical studies, IL-17 inhibition for systemic lupus erythematosus (SLE) has regained attention as a potential therapeutic pathway, after demonstrating disease-modifying capabilities in ankylosing spondylitis. We investigated the clinical associations of interleukin 17 A (IL-17A) in patients with SLE. MATERIAL AND METHODS: A cross-sectional study was performed involving SLE patients (n=102; age: 49 years; 86% female) recruited from a regional registry...

Dysfunctional elimination of cell debris, and the role of opsonins such as pentraxins, is of interest regarding systemic lupus erythematosus (SLE) pathogenesis. Interferon (IFN)-α is typically elevated during SLE flares, and inhibits hepatocyte production of the pentraxin 'C-reactive protein' (CRP), partly explaining the poor correlation between CRP levels and SLE disease activity. The extrahepatically produced 'pentraxin 3' (PTX3) shares waste disposal functions with CRP, but has not been studied extensively in SLE...

Cardiovascular disease is one of the major causes of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Accelerated atherosclerosis is related to traditional (age, hypertension, diabetes mellitus, dyslipidemia, obesity, smoking, and positive family history) and non-traditional, disease-related factors. Traditional risk factors are still more prominent in patients with lupus, as both hypertension and hypercholesterinemia were independently associated with premature atherosclerosis in several SLE cohorts...

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by extensive immune response, including over-activation of T and B cell development of pathogenic autoantibodies, organ damage induced by the formation and deposition of immune complex and the abnormal elevation of type I interferon. Semaphorin5A (Sema5A) is involved essentially in immune cell regulation and is also implicated in the pathogenesis of autoimmune disorders. We aimed to evaluate the role of Sema5A in patients with SLE. Serum levels of Sema5A were tested by enzyme-linked immunosorbent assay (ELISA) in 152 SLE patients and 48 healthy controls...

DNase1l3 is an endonuclease to degrade the chromatin of apoptotic or necrotic cells. Serum DNase1l3 may fulfill the function of clearance of chromatin released into the circulation by dying cells, which can trigger autoimmune responses. To date, it remains unclear whether serum DNase1l3 level associates with the pathogenesis of autoimmune diseases. Sixty-eight patients with dermatomyositis/polymyositis (DM/PM, n = 30), systemic lupus erythematosus (SLE, n = 20) and rheumatoid arthritis (RA, n = 18), as well as 26 healthy blood donors were enrolled in the present study...

Interleukin-34 (IL-34) was initially identified as an alternative ligand for the colony-stimulating factor-1 receptor (CSF-1R) to mediate the biology of mononuclear phagocytic cells. Recently, IL-34 was found to be associated with chronic inflammation, such as in rheumatoid arthritis (RA). Both RA and systemic lupus erythematosus (SLE) are multifactorial autoimmune diseases and are characterized by excessive immune and inflammatory responses. Thus, we investigated whether IL-34 is involved in the pathogenesis of SLE...
