Systemic lupus erythematous is a multi-organ autoimmune disease in which the patient has "lost" self- tolerance and developed immune-complexes containing self-antigen that cause disease through tissue inflammation and multi-organ damage. Patients often have unpredictable flares in symptoms with poorly identified triggers. However, it has been suggested in other literature that exogenous exposures, including ingested beef, cigarette smoke, UV radiation, metal-complexing agents, and infections can contribute to exacerbations and improvements in SLE symptoms...

C1q collagen-like region (CLR) engaging and activating the LAIR-1 inhibitory immunoreceptor represents a non-complement mechanism for maintaining immune quiescence. Given the binding promiscuity of C1q's globular region (gC1q), we hypothesized that C1q concurrently associates with distinct inhibitory immunoreceptors to produce C1q-mediated modulatory networking. Like LAIR-1, CD33 inhibitory immunoreceptors are highly expressed on monocytes. Binding CD33 restricts cell activation/differentiation; however, natural ligands for CD33 remain elusive...

TREX1/DNASE III, the most abundant 3'-5' DNA exonuclease in mammalian cells, is tail-anchored on the endoplasmic reticulum (ER). Mutations at the N-terminus affecting TREX1 DNase activity are associated with autoimmune and inflammatory conditions such as Aicardi-Goutières syndrome (AGS). Mutations in the C-terminus of TREX1 cause loss of localization to the ER and dysregulation of oligosacchryltransferase (OST) activity, and are associated with retinal vasculopathy with cerebral leukodystrophy (RVCL) and in some cases with systemic lupus erythematosus (SLE)...

Podocytopathy in systemic lupus erythematosus is characterised by diffuse foot process effacement without significant peripheral capillary wall immune deposits as seen on electron microscopy. Lupus podocytopathy falls outside the scope of the current International Society of Nephrology and the Renal Pathology Society classification of lupus nephritis. We present a case of relapsing podocytopathy with nephrotic syndrome occurring simultaneously with two extra-renal and serological disease flares, which makes it likely that podocytopathy was related to systemic lupus erythematosus activity...

BACKGROUND: Periodontitis results from the interaction between a subgingival biofilm and host immune response. Changes in biofilm composition are thought to disrupt homeostasis between the host and subgingival bacteria resulting in periodontal damage. Chronic systemic inflammatory disorders have been shown to affect the subgingival microbiota and clinical periodontal status. However, this relationship has not been examined in subjects with systemic lupus erythematosus (SLE). The objective of our study was to investigate the influence of SLE on the subgingival microbiota and its connection with periodontal disease and SLE activity...

BACKGROUND: Systemic lupus erythematosus (SLE) is associated with significant impairment of health-related quality of life (HR-QoL). Recently, meeting a definition of a lupus low disease activity state (LLDAS), analogous to low disease activity in rheumatoid arthritis, was preliminarily validated as associated with protection from damage accrual. The LLDAS definition has not been previously evaluated for association with patient-reported outcomes. The objective of this study was to determine whether LLDAS is associated with better HR-QoL, and examine predictors of HR-QoL, in a large multiethnic, multinational cohort of patients with SLE...

Systemic lupus erythematosus (SLE) is a complex disease targeting multiple organs as a result of overactivation of the type I interferon (IFN) system, a feature currently being targeted by multiple biologic therapies against IFN-α. We have identified an estrogen-regulated microRNA, miR-302d, whose expression is decreased in SLE patient monocytes and identify its target as interferon regulatory factor (IRF)-9, a critical component of the transcriptional complex that regulates expression of interferon-stimulated genes (ISGs)...

BACKGROUND: Cut-off values for results interpretation of lupus anticoagulant (LA) detection are poorly investigated. AIMS: (i) To assess whether results from healthy donors were normally distributed and (ii) the between-laboratories differences of cut-off values for screening, mixing and LA confirmation when calculated as 99(th) or 95(th) centiles, and (iii) to assess their impact on LA detection-rate. METHODS: Each of 11 labs using one of the 3 widely-used commercial platforms for LA detection was asked to collect plasmas from 120 healthy donors and to perform screening, mixing and LA confirmation with two methods (activated partial thromboplastin time [APTT]- and dilute Russell viper venom [dRVV]-derived)...

Hydroxychloroquine (HCQ) is known as one of the most fascinating synthetic antimalarial drugs during the last 50 years. It is currently among the most commonly employed medicines for the clinical treatment of rheumatic diseases, especially systemic lupus erythematosus and rheumatoid arthritis. In related mechanism studies, it has been found that HCQ possesses various immunomodulatory and anti-inflammatory activities. In addition, the effects of HCQ on anti-platelet, metabolic pathways, and antineoplasticity have also been disclosed in more recent studies...

Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune disease predominantly affecting women of childbearing age. New classification criteria for SLE have greater sensitivity and therefore improve the diagnostic certainty for some patients, especially those who may previously have been labelled as having undifferentiated symptoms. Uncontrolled disease activity leads to irreversible end-organ damage, which in turn increases the risk of premature death; early and sustained control of disease activity can usually be achieved by conventional immunosuppressant therapy...

OBJECTIVE AND AIM: A significant incidence of systemic lupus erythematosus (SLE), the severity of lupus nephritis and varying responses to treatment rationalize the search for novel biomarkers of disease activity. The aim of the study was to assess whether antibodies against monomeric C reactive protein (anti-mCRP) are associated with the presence of lupus nephritis, correlate with disease activity, and whether they can serve to evaluate a response to treatment. METHODS: The study involved 74 patients with lupus nephritis, 29 patients with systemic lupus without renal involvement and 31 patients with primary glomerulonephritis; the control group included 31 healthy volunteers...

Systemic lupus erythematosus (SLE) is a polygenic pathological disorder which involves multiple organs. Self-specific B cells play a main role in the lupus pathogenesis by generating autoantibodies as well as by serving as important autoantigen-presenting cells. Autoreactive T lymphocytes, on the other hand, are responsible for B cell activation and proliferation, and cytokine production. Therefore, both factors promote the idea that a down-modulation of activated self-reactive T and B cells involved in the pathogenic immune response is a reasonable approach for SLE therapy...

Interleukin-1 receptor-associated kinase (IRAK) 4 mediates host defense against infections. As an active kinase, IRAK4 elicits full spectra of myeloid differentiation primary response protein (MyD) 88-dependent responses, while kinase-inactive IRAK4 induces a subset of cytokines and negative regulators whose expression is not regulated by mRNA stability. IRAK4 kinase activity is critical for resistance against Streptococcus pneumonia, but its involvement in autoimmunity is incompletely understood. In this study, we determined the role of IRAK4 kinase activity in murine lupus...
