NEW YORK (Reuters Health)—Commensal microbes in the gut can activate retina-specific T cells that go on to cause autoimmune uveitis in a mouse model, researchers report. “These findings allow us to understand the biological basis for the disease,” lead author of the study, Dr. Rachel Caspi from National Eye Institute at the NIH in Bethesda,…
Patients Don’t Realize Smoking Worsens Inflammatory Bowel Disease
(Reuters Health)—Doctors know smoking can increase the risk for certain common inflammatory bowel diseases (IBD), but many patients haven’t gotten the message, a new study suggests. Out of 239 patients with two common types of IBD (Crohn’s disease and ulcerative colitis) only half were aware of the smoking risks associated with these conditions. “The take-home…
Catastrophic Antiphospholipid Syndrome with Pulmonary Hemorrhage: A Case Report
Antiphospholipid syndrome (APS) is an autoimmune condition characterized by hypercoagulability often manifested as recurrent thrombosis or pregnancy complications, with persistently circulating antiphospholipid (aPL) antibodies or lupus anticoagulant. Catastrophic APS (CAPS), also known as Asherson syndrome, occurs in less than 1% of cases of APS and involves occlusive microangiopathy in at least three organ systems.1 Case…
Can Systemic Inflammation Influence Mood?
The Friday night press release: When a politician or any public figure needs to disclose unfavorable news, chances are they will release it sometime on a late Friday afternoon or evening, hoping that nobody is paying attention. In fact, this behavior was coined “the take out the trash day” on the television political drama, The…
Biomarkers May Help Differentiate Crohn’s From Colitis
NEW YORK (Reuters Health)—Serum biomarkers can discriminate between Crohn’s disease (CD) and ulcerative colitis (UC), according to Danish and Dutch researchers. “The biomarker assays measure neo-epitopes, which are fragments of extracellular matrix protein degradation,” Joachim Høg Mortensen, a PhD student at Nordic Bioscience in Herlev, Denmark, told Reuters Health by email. “These neo-epitopes are increasingly…
Psoriatic Disease Linked to Higher Risk of Uveitis & Vice Versa
NEW YORK (Reuters Health)—Two classes of inflammatory diseases, uveitis and psoriatic disease, appear linked, as a diagnosis of one increases the risk of developing the other, new research has found. A study of Danish patient registries found nearly triple the rate of uveitis among patients with psoriatic arthritis compared to the general population, and double…
Skin Complications of Anti-TNF Therapy Common in IBD
NEW YORK (Reuters Health)—Dermatologic complications hit about one in five patients with inflammatory bowel disease (IBD) on anti-tumor necrosis factor (anti-TNF) therapy, leading to discontinuation of treatment, a French study finds. Dr. Laurent Peyrin-Biroulet, from University Hospital of Nancy, and colleagues note that dermatological complications of anti-TNF therapy are known to occur frequently in IBD…
Adalimumab Remains Safe, Effective for Psoriasis
NEW YORK (Reuters Health)—In adults with chronic plaque psoriasis, adalimumab (Humira, AbbVie) was generally well tolerated and effective during five years of therapy, according to a new analysis. The interim analysis is from ESPRIT, a 10-year multinational post-marketing registry. “Clinical trials are not the real world,” in part because patients with comorbidities are screened out…
Psoriasis, Psoriatic Arthritis Linked with Arrhythmia
NEW YORK (Reuters Health)—Psoriasis is linked to a higher risk for arrhythmia, independent of classic cardiovascular (CV) risk factors, according to a study from Taiwan. “In my practice, arrhythmia as comorbidity is discussed during patient consultation along with other comorbidities,” said senior author Dr. Tsen-Fang Tsai of the Department of Dermatology at National Taiwan University…
T Cell Exhaustion: A New Strategy for Treating Autoimmune Disease
Researchers in the U.K. have discovered that manipulating T cells to exhaustion in a targeted way may lead to new treatments and predictors for various types of autoimmune diseases…
