A large, international team of rheumatologists, geneticists, hematologists and other researchers has discovered a severe inflammatory syndrome linked to an acquired genetic mutation in the bone marrow of older men. The X-linked syndrome, they found, is caused by a somatic mutation in myeloid stem cells that hobbles the master regulator of a pathway tasked with…
In this large placebo-controlled trial, Sparks et al. examined the predictors and severity of pulmonary adverse events (AEs) in patients taking low-dose MTX. The researchers found that low-dose MTX increased the risk of pulmonary AEs, including possible pneumonitis.

COVID-19 isn’t the only viral infection on the rise across the globe, so is chikungunya, which can cause arthritis-like symptoms and may lead to long-term joint pain.
A strong association between Epstein-Barr virus (EBV) infections and systemic lupus erythematosus (SLE) has been known since the 1970s. Although the etiology of SLE is not fully established, multiple genetic factors and polymorphisms in genes involved in the immune system have been implicated, with environmental factors also contributing to the development of this complex condition….
Case Presentation History of present illness A 66-year-old white woman presented with unexplained, recurrent episodes of high fever, abdominal pain, rash and arthralgias occurring over the previous three years. During typical episodes, the patient experienced flu-like symptoms, followed by fever, abdominal pain and non-bloody diarrhea without tenesmus. Her temperatures were 101–103ºF, with chills lasting up…
In 1905, two pediatricians in Vienna, Austria, published Serum Sickness, a detailed 120-page monograph that was the first to carefully characterize the syndrome.1 The work would go on to become a classic, ultimately helping illuminate many important questions in immunology. Antitoxin Serum Treatments In the late 19th century, researchers were working to develop lifesaving antitoxins…
ACR CONVERGENCE 2020—At the ACR’s fully virtual annual meeting on Saturday, Nov. 7, Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases (NIAID) since 1984, delivered a special lecture on COVID-19, from virology to therapy to vaccine development. Novel Coronavirus, Familiar Vectors When Chinese physicians first reported infections by what…
ACR CONVERGENCE 2020—Among the many ways in which the COVID-19 pandemic has changed the face of modern medicine is the emergence of multisystem inflammatory syndrome in children (MIS-C), a rare but serious condition that shares many features of Kawasaki disease (KD). With this topic in mind, leading pediatric experts from around the world came together…
The COVID-19 global pandemic has disrupted rheumatology clinics and practices all over the world. In the U.S., many providers have used telemedicine to expand access to care for their patients while managing in-person visits. Brett Smith, DO, who practices at the Blount Memorial Physicians Group, East Tennessee Children’s Hospital, Knoxville, spoke with The Rheumatologist about…
