Serological testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies may play a critical role in the management of the worldwide health crisis. Such testing may reveal key information for epidemiology, convalescent plasma therapies and vaccine development. However, the situation is complex, and much is unknown. Although such testing may ultimately be used to…

Live Herpes Zoster Vaccine Fails to Provide Long-Term Protection in RA Patients on Tofacitinib
(Reuters Health)—The live herpes zoster vaccine does not provide reliable long-term protection in rheumatoid arthritis (RA) patients taking tofacitinib, a recent study suggests. Current ACR guidelines conditionally recommend that patients with RA who are 50 years and older be vaccinated against herpes zoster prior to starting therapy with the Janus kinase (JAK) inhibitor tofacitinib or…
Chikungunya Virus Vaccine Shows Promise in Early Clinical Trial
NEW YORK (Reuters Health)—A new chikungunya virus-like-particle vaccine appears to be safe and immunogenic, according to results from a phase 2 trial. “The phase 2 safety, tolerability and immunogenicity were similar to the data seen in an earlier phase 1 study,” Grace L. Chen, MD, of the National Institutes of Health Vaccine Research Center, Bethesda,…
Not All Rheumatoid Factor-Positive Tests Mean RA
Angioimmunoblastic T cell lymphoma (AITL) is an aggressive, peripheral T cell, non-Hodgkin’s lymphoma with an incidence of 0.05 cases per 100,000 person-years in the U.S., and it typically manifests in adults older than 60 years.1,2 AITL was previously known as angioimmunoblastic lymphadenopathy with dysproteinemia, immunoblastic lymphadenopathy or lymphogranulomatosis X, due to the hypothesis that the…
As Lyme Disease Spreads Across the U.S., Stay Alert for Fatal Lyme Carditis
The reach of Lyme disease is expanding across the U.S., and cases may be under-reported. A recent CDC case report describes the experiences of two patients with fatal cases of Lyme carditis…
Study Implicates Epstein-Barr Virus in 7 Autoimmune Diseases
The identification of specific transcription factors linked to the Epstein-Barr virus (EBV) provides new information on the molecular mechanisms underlying the link between EBV and autoimmune disease. A recently published study, “Transcription Factors Operate Across Disease Loci, with EBNA2 Implicated in Autoimmunity,” co-led by John B. Harley, MD, PhD; Leah C. Kottyan, PhD; and Matthew…
Case Report: Diagnosing, Treating Hepatitis B-Linked Polyarteritis Nodosa
Hepatitis B virus (HBV) associated polyarteritis nodosa (PAN) is an increasingly rare vasculitis in developed countries due to advances in HBV vaccination and antiviral therapy. However, the condition does persist, and rheumatologists should consider it when evaluating vasculitis cases. Below, we discuss a case that illustrates the varied clinical presentations PAN can encompass. A high…
The Role of Autoreactive B Cells in Rheumatoid Arthritis
The body uses B cells to produce antibodies that can fight off infection by invading antigens and bacteria. But in rheumatoid arthritis (RA), the immune system produces autoantibodies that work against the body’s proteins to attack joint tissues. Researchers believe this process is helped along by autoreactive B cells that live in bone matter and…
Shingles Vaccine Not the Only Immunization Linked with Gout Flare
NEW YORK (Reuters Health)—The recombinant shingles vaccine (RZV) is associated with an increased risk of gout flare, and a new study suggests other vaccines may trigger flares as well, researchers say. “Our findings are novel because for the first time, we have identified a trigger for gout flares that presumably acts through [an inflammatory] pathway,…
Rheumatology Drugs at a Glance, Part 3: Rheumatoid Arthritis
Over the past few years, biosimilars and other new drugs have been introduced to treat rheumatic illnesses. Some of the conditions we treat have numerous drug options, others have few or only off-label options. This series, “Rheumatology Drugs at a Glance,” provides streamlined information on the administration of biologic, biosimilar and small molecule inhibitor drugs…
