Research has identified a subset of T cells, peripheral helper (TPH) cells, which may promote pathological B cell responses and antibody production in patients with seropositive RA. TPH cells also express chemokine receptors, enabling them to infiltrate inflamed parts of the body and stimulate B cells to produce antibodies…
(Reuters Health)—A web-based program of exercise and coping skills training improves both function and pain in arthritic knees, a new study suggests. This kind of online therapy can greatly improve access to effective, nonsurgical and non-drug relief for people with osteoarthritis of the knee, researchers say. “Osteoarthritis is a leading cause of chronic knee pain…
NEW YORK (Reuters Health)—Fluctuations in the gut microbiome over time could underlie inflammatory bowel disease (IBD), including Crohn’s and ulcerative colitis, researchers suggest. “Both the state and the dynamics of the human gut microbiome in healthy individuals are highly personalized. Although cross-sectional studies have revealed dysbiosis of the gut microbiome in IBD, little is known…
NEW YORK (Reuters Health)—An adherent-invasive E. coli pathotype present in the bowel may contribute to the development of Crohn’s disease-associated spondyloarthritis, researchers say. “Clinical symptoms, including extra-intestinal manifestations, in Crohn’s disease offer a portal into the microbial, immune, and genetic mechanisms underlying disease pathogenesis,” Dr. Randy S. Longman from Weill Cornell Medical College in New…
NEW YORK (Reuters Health)—Intraocular vancomycin may lead to potentially blinding hemorrhagic occlusive retinal vasculitis (HORV), a new study suggests. “The importance of this study was to present in a number of patients overwhelming evidence that rarely, intraocular vancomycin is associated with sight-threatening retinal vascular occlusion,” says lead author Dr. Andre J. Witkin of Tufts Medical…
(Reuters Health)—Women with weaker thigh muscles may be more likely to develop knee osteoarthritis, a recent study suggests. Women with lower knee extensor strength were 47 percent more likely to develop knee arthritis than women who had stronger knee extensors, the study found. Weakness in the knee flexor muscles was associated with 41 percent greater…
WASHINGTON, D.C.—As treatments for rheumatoid arthritis (RA) improve, some related conditions that used to be common in patients with RA are not seen very often anymore, but they still exist and physicians need to know how to identify them. Speaking to attendees at the ACR/ARHP Annual Meeting talk titled Rheumatoid Arthritis—A Case-Based Approach to Selected…
Erdheim-Chester disease (ECD) is a rare, non-Langerhan’s cell histiocytosis characterized by tissue infiltration of CD68-positive and CD1a-negative foamy histiocytes.1 ECD was discovered as a lipid granulomatosis in 1930 by Jakob Erdheim and his pupil, William Chester, and approximately 500 cases have been described to date.1 ECD has a heterogeneous course and prognosis ranging from an…
Guselkumab Improves Active Psoriatic Arthritis New research has revealed that patients with active psoriatic arthritis (PsA) and ≥3% body area of plaque psoriasis benefit from treatment with a human monoclonal antibody known as guselkumab (GUS). GUS is specific for the p19 subunit of interleukin 23 (IL-23). Patients in the Phase 2 clinical trial experienced significant…
WASHINGTON, D.C.—What do treating hand osteoarthritis (OA) in the primary care setting, high financial strain and risk of depression in patients with lupus, prolonged sitting and cardiovascular disease, and sex-specific treatment after total hip arthroplasty have in common? They were all topics presented during a session titled ARHP I: Exemplary Abstracts at the 2016 ACR/ARHP…
