A 14-year-old girl is referred to your office for fatigue and arthralgias. While you’re obtaining her past medical history, she divulges that she has had four episodes of bilateral parotitis, each lasting two weeks. An otolaryngologist evaluated her. She lacked sicca symptoms, had a normal complete blood count (CBC), normal inflammatory markers and a negative…
Progress on Preventing Immune-Related Adverse Events
ATLANTA—One of the hottest topics in medicine is the emerging field of cancer immunotherapy. However, immune-related adverse events (irAEs) are associated with the therapy, and when things go wrong, they can go very, very wrong, said Ryan Sullivan, MD, during the 2019 ACR/ARP Annual Meeting in November. “The guiding principle of cancer immunotherapy is [that]…
Study Says Sjögren’s Patients Have a High Specificity for a Novel Antibody
An antibody previously un-recognized in patients with Sjögren’s syndrome may shed new light on the pathophysiology of one of the most troubling and disabling symptoms in many of these patients. Investigators at Johns Hopkins University, Baltimore, found the anti-calponin 3 antibody had a high specificity for Sjögren’s syndrome, particularly among patients with neuropathies.1 “There is…
Phase 2 Results for Mavrilimumab Are In
Recent data showing sustained, long-term safety and efficacy of mavrilimumab for the treatment of rheumatoid arthritis (RA) confirm and build on prior evidence from phase 2 studies of the potential for this new agent for the treatment of RA. Mavrilimumab is a human monoclonal antibody that blocks a proinflammatory cytokine involved in RA pathogenesis—granulocyte-macrophage colony-stimulating…
Biomarkers for Knee OA
Knee osteoarthritis (OA) accounts for more than 80% of OA disease burden and has doubled in prevalence in the mid-20th century in the U.S. when compared with people who lived during early industrial era (1800s to early 1900s).1 Currently, the diagnostic and treatment armamentaria are limited. Disease progression is measured by joint space narrowing on…
Psoriatic Arthritis Research Continues Hunt for Biomarkers
AMSTERDAM—Molecular signatures in synovial tissue that can be gathered through biopsies are a largely untapped resource that could help guide treatment for rheumatic conditions, an expert said at the EULAR: Annual European Congress of Rheumatology. “I’m convinced that looking into synovial tissue provides us with tools to not only understand mechanisms of disease in rheumatoid…
Case Illustrates the Difficulty Diagnosing Granulomatosis with Polyangiitis
Granulomatosis with polyangiitis (GPA) was first described in the British Medical Journal in 1897 by Scottish otolaryngologist Peter McBride.1 GPA is a relatively rare, systemic necrotizing vasculitis that can make diagnosis challenging. The incidence has been estimated anywhere between two and 12 cases per million.2 GPA mainly affects adults between the ages of 45 and…
Rheumatoid Arthritis May Confer Higher Cardiac & Infection Risks
NEW YORK (Reuters Health)—Patients with rheumatoid arthritis (RA) are at increased risk of serious infections, myocardial infarction (MI) and coronary heart disease (CHD), an analysis of Medicare claims data suggests. “Higher disease activity as measured by a panel of biomarkers was associated with higher rates of hospitalized infections, MI and CHD events. These findings add…
CCL2 Cytokine Serves as Biomarker in Interstitial Lung Disease
A recent prospective, observational cohort study of potential clinical biomarkers for progression to interstitial lung disease (ILD) in patients with early systemic sclerosis (SSc) found that higher levels of CCL2 circulating in their plasma predicted both faster ILD progression and poorer survival rates than in those with lower levels.1 CCL2, also known as monocyte chemoattractant…
Potential Biomarker for APS Identified
New research examines the role of factor Xa in the pathology of antiphospholipid syndrome (APS) and systemic lupus erythematosus-associated APS. Researchers found that FXa stimulation was mediated by protease-activated receptors and enhanced by IgG from FXa reactive antibody positive patients, which may make IgG FXa reactivity a novel biomarker for future research…
