CHICAGO—Caryn A. Libbey, MD, clinical associate professor of medicine at Boston University School of Medicine, described the evolving in our understanding of amyloid at the ACR’s State-of-the-Art Clinical Symposium in April. Amyloidosis is a rare disease that is often underdiagnosed and undertreated. “Even though this disease has been around for 150 years, I still consider it…
New Genetic Loci Identified, Epigenome Explored in Juvenile Idiopathic Arthritis
WASHINGTON, D.C.—Researchers have identified nine new genetic loci linked with juvenile idiopathic arthritis (JIA), along with evidence that at least some of them likely play a functional role, such as cytokine signaling and T cell expression. The findings were presented in an abstract session at the 2016 ACR/ARHP Annual Meeting, which also included a presentation…
Fellows Forum Case Report: Neuromyelitis Optica
Case Presentation The patient was a 42-year-old African American female diagnosed with systemic lupus erythematosus (SLE) based on the findings of polyarthritis, malar and discoid rash, fatigue, positive double-stranded DNA (dsDNA) ribonucleoprotein and Smith antibodies, and low serum complement levels. Her SLE had been well controlled on hydroxychloroquine 400 mg daily, oral methotrexate 25 mg…
Metagenomic Deep Sequencing for Uveitis Enhances Traditional Diagnostic Testing
Throughout their training and practice, physicians become adept at pattern recognition as a means to efficiently connect and synthesize seemingly disparate laboratory, physical exam, and radiologic and historical findings into a coherent theory for what likely ails the patient sitting in front of them. This inductive method of reasoning is necessary because, based on these…
Conformational Flexibility in HLA-B27 Provides Clues to Development of Ankylosing Spondylitis
Understanding how human leukocyte antigen (HLA) class I molecule B27 promotes spondyloarthritis has intrigued researchers for four decades. Although the association between the single gene variant HLA-B27—specifically some of its subtypes—with ankylosing spondylitis (AS) is particularly strong, how HLA-B27 directly influences disease development has not yet been clearly explained, although hypotheses continue to be generated….
