Bizarre appearance of chronic cutaneous lupus erythematosus of face mimicking factitial dermatitis.

Old dermatological wisdom says that syphilis and lupus are great imitators. Cutaneous manifestations of lupus erythematosus (LE) are usually characteristic, however, some patients may present with a less typical clinical picture. Correct diagnosis of cutaneous lupus erythematosus (CLE) requires a high level of clinical suspicion and understanding of broad differential diagnosis. Early lesions of C...

Factors associated with adverse pregnancy outcomes in women with systematic lupus erythematosus.

The aim of this prospective study was to determine clinical factors associated with adverse pregnancy outcomes in women with systematic lupus erythematosus (SLE). Fifty-six pregnancies from 46 women with SLE were enrolled. Risk factors for pregnancy loss, premature delivery, hypertensive disorders of pregnancy (HDP), and light-for-date neonate (LFD), were evaluated. Univariate and multivariate log...

Nephrotic syndrome due to lupus-like glomerulonephritis in an HIV-positive patient.

Lupus nephritis, a well-known complication in systemic lupus erythematosus, is characterised by a proliferative glomerulonephritis or membranous nephropathy along with a full-house immunofluorescence pattern on renal biopsy. There are very few exceptions in which similar histopathological findings are present, but case reports show that an increasing number of HIV-positive patients (mostly black A...

Short-term efficacy and safety of rituximab therapy in refractory systemic lupus erythematosus: results from the British Isles Lupus Assessment Group Biologics Register.

To describe the baseline characteristics of SLE patients requiring biologic therapy in the UK and to explore short term efficacy and infection rates associated with rituximab (RTX) use.

Recent developments in systemic lupus erythematosus pathogenesis and applications for therapy.

Systemic lupus erythematosus (SLE) pathogenesis is complex. Aberrancies of immune function that previously were described but not well understood are now becoming better characterized, in part through recognition of monogenic cases of lupus-like disease.

Abnormal B-cell development in Systemic Lupus Erythematosus: what the genetics tell us.

Systemic Lupus Erythematosus (SLE) is an autoimmune disease characterised by B-cell dysfunction, production of autoantibodies directed towards cellular and nuclear components and tissue damage caused by immune complex deposition and inflammation. It largely affects women in the 3rd and 4th decades of life and is associated with significant morbidity and mortality. In healthy individuals, B-cells w...

Extensively reorganized systemic lymph nodes provide a feasible environment for self-reactivity in lupus-prone NZB/NZW F1 mice.

Lymphadenopathy is a frequently observed symptom in systemic lupus erythematosus, although the immunological role of lymph nodes (LNs) in systemic autoimmunity remains largely unknown. Here, we performed comprehensive and systematic analyses of LNs in lupus-prone NZB × NZW F1 (BWF1) mice, demonstrating extensive tissue reorganization of the systemic LNs with follicular expansion, hyper germinal c...

A Population-based Study of Perinatal Infection Risk in Women with and without Systemic Lupus Erythematosus and their Infants.

Increased risk of adverse birth outcomes is well described in women with systemic lupus erythematosus (SLE), but risk of maternal or infant infection in the peripartum period has not been well studied. We conducted a population-based cohort study of infection risk in women with and without SLE and their infants.

High Health Care Utilization Preceding Diagnosis of Systemic Lupus Erythematosus in Youth.

Childhood-onset systemic lupus erythematosus (SLE) is associated with high risk for organ damage, which may be mitigated by early diagnosis and treatment. We characterized health care utilization for youth in the year preceding SLE diagnosis compared to controls.

Neonatal Lupus - Case series of a tertiary hospital.

Neonatal lupus (NL) is a very rare condition with an estimated incidence of 1 in 20.000 pregnancies. It is caused by the transplacental passage of autoantibodies anti-Ro/SSA, antiSa/SSB antibodies and/or anti-U1 RNP antibodies into the fetal circulation. The mother may be completely asymptomatic or have a known inflammatory rheumatic disease, such as Sjögren syndrome (SS) or Systemic Lupus Erythe...

Lupus nephritis progression in FcγRIIB-/-yaa mice is associated with early development of glomerular electron dense deposits and loss of renal DNase I in severe disease.

FcγRIIB-/-yaa mice develop severe lupus glomerulonephritis due to lack of an inhibitory immune cell receptor combined with a Y-chromosome linked autoimmune accelerator mutation. In the present study, we have investigated nephritis development and progression in FcγRIIB-/-yaa mice to find shared features with NZB/NZW F1 lupus prone mice and human disease. We sacrificed 25 male FcγRIIB-/-yaa mice...

Cytokine and autoantibody clusters interaction in systemic lupus erythematosus.

Evidence supports the existence of different subphenotypes in systemic lupus erythematosus (SLE) and the pivotal role of cytokines and autoantibodies, which interact in a highly complex network. Thus, understanding how these complex nonlinear processes are connected and observed in real-life settings is a major challenge. Cluster approaches may assist in the identification of these subphenotypes, ...

The IL-21-mTOR axis blocks treg differentiation and function by suppression of autophagy in patients with systemic lupus erythematosus.

The mechanistic target of rapamycin (mTOR) has become a therapeutic target in systemic lupus erythematosus (SLE). mTOR regulates normal T-cell lineage specification, including development of regulatory cells (Tregs). Therefore, we investigated whether mTOR is activated within Tregs and causes their depletion and dysfunction in patients with SLE.

Peer-to-peer mentoring for African American women with lupus: A feasibility pilot.

To examine the feasibility and potential benefits of peer mentoring to improve the disease self-management and quality of life of individuals with systemic lupus erythematosus (SLE).

Lupus Nephritis: Persistent Challenges, New Approaches.

Editorial commentary for Dhakal: Heart failure in systemic lupus erythematosus: A problem to address.

Disease trends over time and CD4(+)CCR5(+) T-cells expansion predict carotid atherosclerosis development in patients with systemic lupus erythematosus.

Patients with Systemic Lupus Erythematosus (SLE) present increased cardiovascular mortality compared to the general population. Few studies have assessed the long-term development and progression of carotid atherosclerotic plaque in SLE patients. Our aim was to investigate the association of clinical and laboratory markers of disease activity and classical cardiovascular risk factors (CVRF) with c...

Characterization and classification of lupus patients based on plasma thermograms.

Plasma thermograms (thermal stability profiles of blood plasma) are being utilized as a new diagnostic approach for clinical assessment. In this study, we investigated the ability of plasma thermograms to classify systemic lupus erythematosus (SLE) patients versus non SLE controls using a sample of 300 SLE and 300 control subjects from the Lupus Family Registry and Repository. Additionally, we eva...

Chloroquine Autophagic Inhibition Rebalances Th17/Treg-Mediated Immunity and Ameliorates Systemic Lupus Erythematosus.

Imbalanced cellular immunity is critical to the pathogenesis of systemic lupus erythematosus (SLE). Recently, autophagy has emerged as a key homeostatic mechanism in T lymphocytes. This study was conducted to explore the impact of autophagy on the Th17/ regulatory T (Treg) immune imbalance in SLE.

Profiling analysis of circulating microRNA in peripheral blood of patients with class IV lupus nephritis.

Renal involvement in Systemic Lupus Erythematous (SLE) patients is one of the leading causes of morbidity and a significant contributor to mortality. It's estimated that nearly 50% of SLE individuals develop kidney disease in the first year of the diagnosis. Class IV lupus nephritis (LN-IV) is the class of lupus nephritis most common in Colombian patients with SLE. Altered miRNAs expression levels...

The perspectives of medical specialists from different disciplines on the management of systemic lupus erythematosus: an interview study.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease that can affect multiple organ systems, with specialists from many disciplines often involved, which may lead to inconsistent care. We aimed to describe the attitudes and perspectives of specialists from different medical disciplines on the management of people with SLE.

Safety, pharmacokinetics and pharmacodynamics of single rising doses of BI 655064, an antagonistic anti-CD40 antibody in healthy subjects: a potential novel treatment for autoimmune diseases.

The CD40-CD40L pathway is a promising treatment target for autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus and lupus nephritis. The safety, pharmacokinetics and pharmacodynamics of BI 655064, a novel humanised antagonistic anti-CD40 monoclonal antibody, were investigated in this first-in-human trial.

Asthma in children of mothers with systemic lupus erythematosus and the role of preterm birth.

Systemic lupus erythematosus (SLE) and asthma share inheritable IgE-related pathophysiology, but the association between maternal SLE and asthma in the offspring has not been explored. Our aim was to investigate the association between maternal SLE during pregnancy and childhood asthma and examine the role of preterm birth as a mediator of the association using Swedish register data.
