Interactions between an individual’s genetic background and their exposure to environmental factors are thought to result in a cascade of immune reactions, ultimately leading to the development of autoimmune diseases such as rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), systemic lupus erythematosus (SLE) and juvenile dermatomyositis.1,2 For example, an environmental factor that conclusively affects susceptibility…
New research links the RNA binding protein Ro60 with SLE pathogenesis and disease-causing inflammation…
The field of rheumatology took center stage when a handful of speakers discussed trends and research during a disease-oriented session of the 2015 Federation of Clinical Immunity Societies (FOCIS 2015) conference held in San Diego in June. Neutrophils in SLE Mariana Kaplan, MD, chief of Systemic Autoimmunity Branch at the National Institute of Arthritis and…
The differences between Caucasian and minority patients with lupus are striking: In almost all aspects of the disease, black, Hispanic and many Asian lupus patients do poorly compared with their white counterparts. Although racial disparities in outcomes in the practice of medicine are widespread, the scope and degree of the differences in lupus is, with…
CHICAGO—With the approval of the Jak inhibitors (i.e., jakinibs) tofacitinib and ruxolitinib—and others being investigated—rheumatologists need to arm themselves with an understanding of these drugs so they can think critically when evaluating them and deciding how to use them, said John O’Shea, MD, chief of the Molecular Immunology and Inflammation Branch of and scientific director…
Patients with systemic lupus erythematosus (SLE) are characterized by high-titer, highly specific, isotype-switched antibodies against DNA and RNA. Patients have both CD4+ T helper (Th) cell- dependent as well as Th cell-independent autoantibody production. Two mouse models of lupus demonstrate T-cell–independent autoantibody production: the pristane model of lupus, as well as in the MRL/lpr mouse…
New research published in May indicates a possible connection between B cells and the occurrence of systemic lupus erythematosus symptoms.
In 1984, I wrote my first prescription for the antimalarial drug, hydroxychloroquine (Plaquenil), for a 28-year-old woman with SLE. She was considerably overweight, with inflammatory arthritis and a photosensitive rash, and I worried that oral corticosteroids would tip her over into diabetes. I presented the case to my attending, Steven Malawista, MD, at the Yale…
New research compares pathogenic immune response in SLE with immune response that contributes to atherosclerotic plaque
Case report highlights important twist to differential diagnosis of neuropsychiatric lupus
