OBJECTIVE: The increased survival in Systemic Lupus Erythematosus (SLE) patients implies the development of chronic damage, occurring in up to 50% of cases. Its prevention is a major goal in the SLE management. We aimed at predicting chronic damage in a large monocentric SLE cohort by using neural networks. METHODS: We enrolled 413 SLE patients (M/F 30/383; mean age ± SD 46.3±11.9 years; mean disease duration ± SD 174.6 ± 112.1 months). Chronic damage was assessed by the SLICC/ACR Damage Index (SDI)...

BACKGROUND: Serum immunoglobulin G targeting the astrocyte water channel aquaporin-4 (AQP4) in the central nervous system (CNS) is a biomarker for neuromyelitis optica spectrum disease (NMOSD). Co-existence of NMOSD with systemic lupus erythematosus (SLE) putatively suggests susceptibility to antibody-mediated autoimmune disease. OBJECTIVE: To estimate the prevalence of NMOSD in SLE and investigate the immunogenetic background for an association of NMOSD and SLE...

OBJECTIVES: We aimed to summarize the evidence examining factors that predict differential response to mycophenolate mofetil (MMF) in systemic lupus erythematosus (SLE). METHODS: Systematic searches of randomized clinical trials (RCT) to identify predictors of the effects of MMF (moderators), and cohort studies to explore prognostic factors associated with MMF outcomes (response, relapse, or adverse events) were performed. Two reviewers independently assessed the methodological quality of RCTs using the Cochrane Collaboration risk of bias tool and cohort studies using the QUality In Prognosis Studies tool...

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...

BACKGROUND: Systemic lupus erythematosus (SLE) is a common autoimmune connective tissue disease that mainly harms kidneys, heart, lungs, and nervous system. Effects of surgical stimulus and anesthesia combined with SLE-related pathologies may increase morbidity and mortality. Therefore, we aimed to evaluate the association between SLE (versus none) and postoperative renal, cardiac, and in-hospital mortality complications among patients undergoing major surgeries. METHODS: We obtained censuses of 2009 to 2011 inpatient hospital discharges across 7 states and conducted a retrospective cohort study by using International Classification of Diseases and Injuries, Version 9, diagnosis codes, procedure codes, and present-on-admission indicators...

Introduction/objectives autoantibodies to types I and IV collagen have been described in rheumatic fever and infective endocarditis. We tried to elucidate if an autoimmune response against collagens I and IV exists, associated with heart valve disease in systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). A cohort of 172 patients with SLE (n = 79), primary APS (PAPS, n = 83), and secondary APS (n = 10) were assessed for valvulopathy by transthoracic echocardiograms. Autoantibodies to types I and IV collagen were assessed in patients and 50 controls, setting autoantibody positivity at two standard deviations above the mean antibody level of controls...

OBJECTIVES: Deregulated production of interleukin (IL)-17 and IL-21 contributes to the pathogenesis of autoimmune disorders such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Production of IL-17 and IL-21 can be regulated by ROCK2, one of the two Rho kinases. Increased ROCK activation was previously observed in an SLE cohort. Here, we evaluated ROCK activity in a new SLE cohort, and an RA cohort, and assessed the ability of distinct inhibitors of the ROCK pathway to suppress production of IL-17 and IL-21 by SLE T cells or human Th17 cells...

In spite of the interest for chronic renal diseases (CKD) in pregnancy data on specific diseases is fragmentary; while recent studies analysed the most common glomerulonephritides (GN), none was addressed at GN as a group. The aim of our study was to analyse the main pregnancy-related outcomes in GN patients in a large multicentre cohort. Patients with a diagnosis of GN were selected from the TOCOS cohort (TOCOS: TOrino Cagliari Observational Study): out of 714 singleton deliveries GN was the diagnosis in 126; lupus GN and IgA nephropathy accounted for 37 and 33 cases; 1418 low-risk singleton deliveries followed-up in the same Centers served as controls (non diabetic, non nephropathic, non obese women, without any other known chronic illness; pregnancies after ovodonation or in vitro fertilisation were excluded, if declared)...
