Preclinical models have provided important insights into the pathogenesis of OA and potential pathways for therapeutic intervention, including adenosine. Ticagrelor and clopidogrel are both used in patients with coronary artery disease, but only ticagrelor increases extracellular adenosine levels. In this study, treatment with ticagrelor was associated with a 29% lower risk of developing OA than treatment with clopidogrel over five years of follow-up.
Gout: The State of the Science
In light of the release of the ACR’s new gout guideline, it’s not surprising that 50 abstracts of studies on various aspects of gout were accepted at ACR Convergence 2020. Here, we highlight just a few:
Commensal Cross-Reactive T & B Cells Trigger Autoimmunity
Researchers are finding that antigens from the microbiota may play a role in the development of autoimmunity.
FDA Approves Golimumab for Patients with pJIA & Psoriatic Arthritis
The FDA has approved golimumab for the treatment of pediatric patients with active polyarticular juvenile idiopathic arthritis or active psoriatic arthritis…
Duke Researchers Create a Type 1, Type 2 Lupus Disease Model
A new disease model for lupus tackles issues with fatigue and other serious conditions that, although quite common among patients, get less attention because they fall outside classic symptoms associated with inflammation, a debilitating force behind systemic lupus erythematosus (SLE). The model features subtypes to categorize two main groups of symptoms into type 1, typically…
Hand Pain Depends on More Than Osteoarthritis Severity & Psych Profile
Pain is the main reason patients with osteoarthritis (OA) seek medical help because of the substantial burden it imposes and its impact on quality of life. Pain can actually change the way the central nervous system works. This central sensitization results in more pain with less provocation. And according to results from an observational study…
Race As a Risk Factor for Sjögrens Syndrome
A new study in Arthritis Care & Research highlights potential differences in incidence, the presentation of prominent symptoms and laboratory findings in African Americans and Native Americans with Sjögren’s syndrome compared with white populations. Native Americans appear to be at higher risk of the disease, although they often display fewer of the classic symptoms. Importantly,…
Researchers Seek ANCA-Associated Vasculitis Subtype Markers
New research on complement activation in anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis underscores its important role in the pathogenesis of this disease, an autoimmune condition defined by inflammation of small- and medium-caliber blood vessels.1 ANCA testing is commonly performed to help diagnose granulomatosis with polyangiitis and microscopic polyangiitis, both of which are forms of ANCA-associated…
A New Frailty Index Aids Lupus Assessment
A recently developed frailty index may be a valuable way to quantify vulnerability in patients with systemic lupus erythematosus (SLE), according to a study published in Arthritis & Rheumatology.1 When evaluating SLE, physicians consider a patient’s disease activity, organ damage and health-related quality of life. The Systemic Lupus International Collaborating Clinics (SLICC)/ACR Damage Index (SDI)…
Case Report: A 40-Year-Old Man with Vasculitic Neuropathy
Ironically, chronic exposure to minocycline has also been associated with a variety of autoimmune syndromes, including drug-induced lupus, autoimmune hepatitis, serum sickness and vasculitis.1 Minocycline is associated with an 8.5-fold increased risk of drug-induced lupus.2 Minocycline and nitrofurantoin are implicated in 90% of cases of drug-induced autoimmune hepatitis.3 Minocycline-induced vasculitis is much less common and,…
