Neutrophil extracellular traps-associated markers are elevated in patients with systemic lupus erythematosus

AbstractNeutrophil extracellular traps (NETs) are the main source of autoantigens in systemic lupus erythematosus (SLE). The aim of this study was to evaluate the clinical importance of NETs-associated markers in SLE. We compared NETs-associated markers in SLE patients (n = 111) with healthy controls (n = 50). Moreover, in 35 patients with drug-naïve SLE (n = 35), we investigated correlation between NETs-associated markers [DNase I concentration, myeloperoxidase (MPO) activity, anti-MPO antibodies, cell-free DNA (cfDNA), NETolytic activity] with serological parameters [anti-dsDNA antibodies, C3, C4 and B-cell activating factor (BAFF) levels] and d isease activity measured by modified SLE Disease Activity Index (M-SLEDAI-2K). In comparison with healthy controls, SLE patients had higher cfDNA, MPO activity, anti-MPO antibodies (p

ParikhMembranous lupus nephritis (MLN) (Class V lupus nephritis [LN]) is a distinct form of LN defined by the presence of subepithelial immune complex deposits seen on kidney biopsy. MLN is often associated with the nephrotic syndrome. The histology of MLN closely resembles that of idiopathic (primary) membranous nephropathy (pMN). However, MLN typically has abundant mesangial deposits that are absent in primary membranous nephropathy. The clinical presentation, management, and prognosis of MLN d...

ChakravartyLupus nephritis is the most common organ-threatening manifestation of systemic lupus erythematosus, affecting more than one-third of patients. Induction of remission and maintenance of relapse-free disease have been and continue to be a critical focus of investigation. Because the need for renal replacement therapy in those with an insufficient response to therapy is associated with significantly increased morbidity and mortality, providers and patients are willing to accept moderate...

Here we review the diagnosis and management of occlusive renal vascular lesions due to APS and other TMAs, with a focus on patients with SLE and lupus nephritis. The presence of a thrombotic event, unexplained hypertension, thrombocytopenia, or hemolytic anemia should prompt considerat...

However, in rare instances, systemic lupus erythematosus patients with nephrotic syndrome have kidney biopsy findings of normal glomeruli or focal segmental glomerulosclerosis lesions, with or without...

Several LN classifications have been devised in an effort to inform treatment decision and predict prognosis, and these are being further updated. In this review, we will examine the role of diagnostic as well as repeat kidney biopsy in the management of LN, including the pot...

PowellLupus nephritis (LN) occurs in up to 60% of SLE patients, and is a leading cause of disability and death. Current treatment of LN consists of a combination of high dose corticosteroids that non-specifically decrease inflammation and cytotoxic medications that reduce auto-antibody production. That combination of therapy is associated with significant side effects while remission rates remain inadequate. Since the introduction of biologics into the pharmacological armamentarium, there has be...

Unfortunately, treatments for LN have not changed over the past 15 years. Despite continued efforts to elucidate the pathogenesis of LN, no new drugs have yet replaced the standard-of-care regimens of cyclophosphamide or mycophenolate mofetil plus high-dose corticosteroids. The significant limitations o...

These hormonal and immunologic changes may affect disease activity in systemic lupus erythematosus. Conversely, lupus nephritis and its complications may adversely impact pregnancy. Systemic lupus erythematosus increases the risk of pre-eclampsia and its complications, including preterm birth and intrauterine growth restriction. Comorbiditie...

Although the incidence rates of ESKD from LN stopped rising in recent years, racial disparities in waiting time, pre-emptive kidney transplant, and transplant outcomes still exist. Patients with LN who progress to ESKD tend to be female, of African ancestry, and young. Kidney transplantation is safe in this population and associated with a substantial survival benefit, prima...
