IgE in lupus pathogenesis: Friends or foes?

Systemic lupus erythematosus (SLE) is a complex autoimmune disease involving multiple immunological pathways. Recently, several studies have suggested an implication of Immunoglobulin E (IgE) in the pathophysiology of SLE. In the Lyn-/- and FcγIIB-/-.Yaa lupus mouse models, autoreactive IgE activate basophils, and promote a Th2 environment with, subsequently, production of autoantibodies by plasm...

The prevalence of HLA alleles in a lupus nephritis population.

Systemic lupus erythematosus (SLE) is a severe autoimmune disease that involves multiple organ systems. Lupus nephritis (LN) is a complication of SLE and is associated with poor survival and high morbidity. Many genomic studies have been performed worldwide, and several histocompatibility leukocyte antigen (HLA) loci are linked to lupus susceptibility.

Increased circulating CD4+CXCR5+FoxP3+ follicular regulatory T cells correlated with severity of systemic lupus erythematosus patients.

As one specialized subset of regulatory T cells (Tregs), follicular regulatory T cells (TFR) could suppress follicular helper T cells (TFH) and B cells in germinal centers to maintain immune homeostasis. The unbalance of TFR and TFH cells could result in abnormal germinal center responses and contribute to pathogenesis of autoimmune diseases. However, the role of TFR cells in systemic lupus erythe...

Measuring Disease Damage and its Severity in Childhood-Onset Systemic Lupus Erythematosus.

To describe the frequency and types of disease damage occurring with childhood-onset systemic lupus erythematosus (cSLE) as measured by the 41-item Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI), and to assess the SDI's ability to reflect damage severity.

The correlations of psychological status, quality of life, self-esteem, social support and body image disturbance in Chinese patients with Systemic Lupus Erythematosus.

This study aimed (i) to complement existing research by focusing on body image disturbance issues in Chinese Systemic Lupus Erythematosus (SLE) patients; (ii) to investigate how Chinese patients make sense of disease diagnosis and perceived cultural influences within the context of their SLE. A total of 118 SLE patients underwent standardized laboratory examinations and completed several questionn...

Epratuzumab: reveille or requiem? teachable moments for lupus and sjogren's clinical trials.

The story of how anti TNFs went from bench to bedside in 5 years is an inspirational, satisfying narrative that changed the lives of millions of patients suffering from rheumatoid arthritis and the spondyloarthropathies. Rituximab received approval for ANCA positive vasculitis on the basis of a single study with fewer than 200 subjects. Unfortunately, attempts to obtain approval for drugs for syst...

Efficacy of Epratuzumab, an Anti-CD22 Monoclonal IgG Antibody, in Systemic Lupus Erythematosus Patients with Associated Sjögren's Syndrome: Post-hoc Analyses from the EMBODY Trials.

EMBODY 1 (NCT01262365) and EMBODY 2 (NCT01261793) investigated the efficacy and safety of epratuzumab, a CD22-targeted humanized monoclonal IgG1 antibody, in patients with systemic lupus erythematosus (SLE). The studies showed no significant difference from placebo in primary or secondary clinical outcome measures, but did demonstrate B-cell-specific immunological activity.

Hemostatic Abnormalities in Multiple Myeloma Patients

Background: Multiple myeloma (MM) is a neoplastic plasma cell disorder characterized by clonal proliferation of plasma cells in the bone marrow. Diverse hemostatic abnormalities have been reported in patients with myeloma which predispose to bleeding and also thrombosis. Methods: Complete blood count, biochemical parameters and parameters of hemostasis i.e. platelet count, prothrombin time (PT), a...

Confirmation of Echinococcus canadensis G8 and G10 in Idaho Gray Wolves ( Canis lupus) and Cervids.

  We confirm the presence of Echinococcus canadensis genotypes G8 and G10 in gray wolves ( Canis lupus) and cervids in Idaho. Our results demonstrated that cystic echinococcosis remains a potential public health issue, indicating the need for regular deworming of domestic dogs, who often act as potential bridge hosts.

iRhom2 promotes lupus nephritis through TNF-α and EGFR signaling.

Lupus nephritis (LN) often results in progressive renal dysfunction. The inactive Rhomboid 2 (iRhom2) is a newly identified key regulator of A disintegrin and metalloprotease 17 (ADAM17), whose substrates, such as TNF-α and heparin-binding EGF (HB-EGF), have been implicated in the pathogenesis of chronic kidney disease. Here we demonstrate that deficiency of iRhom2 protects the lupus-prone Fcgr2b...

Lupus miliaris disseminatus faciei.

Lupus miliaris disseminatus faciei is a rare inflammatory dermatosis of unknown etiology that primarily affects young adults. Clinically, it is characterized by an asymptomatic papular eruption mainly involving the central face, typically on and around the eyelids. Characteristic histopathological features include dermal epithelioid cell granulomas with central necrosis and surrounding lymphocytic...

Serum calcification propensity is independently associated with disease activity in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is associated with severe cardiovascular complications. The T50 score is a novel functional blood test quantifying calcification propensity in serum. High calcification propensity (or low T50) is a strong and independent determinant of all-cause mortality in various patient populations.

Glucocorticoid use and factors associated with variability in this use in the Systemic Lupus International Collaborating Clinics Inception Cohort.
