ACR Convergence 2020—In May 2020, the ACR published its updated guideline for the management of gout.1 It followed on the heels of a 2017 gout guideline published by the American College of Physicians.2 Although the guidelines provide similar recommendations on the treatment of acute gout, they differ importantly in the use of uric acid-lowering therapy…

Study: DPP4 Inhibitors Yield Promise for Systemic Sclerosis Treatment
A recent paper in Arthritis & Rheumatology opens up the possibility of a new research avenue to treat systemic sclerosis: dipeptidyl peptidase 4 (DPP4) inhibitors, a previously approved therapy for type 2 diabetes.1 Work in mouse models and on skin samples from systemic sclerosis patients suggests these drugs pose a promising area of future translational…
What’s the Role of Epstein-Barr Virus Reactivation in Lupus Development?
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….
A Look Back at Pirquet & Schick’s Influential Serum Sickness Study
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…
Case Report: A COVID-19 Mimic
A 67–year-old white woman with primary Raynaud’s phenomenon presented following a week of progressively worsening shortness of breath, dry cough and generalized malaise. An avid tennis player, she first noticed dyspnea while playing, but a few days later grew short of breath even at rest. She went to an urgent care center, where a computed…
Case Report: What’s Causing This Severe Case of Rhabdomyolysis?
Rhabdomyolysis is a clinical syndrome characterized by muscle tissue necrosis and release of intramuscular components into the circulation. Typical manifestations include muscle pain and myoglobinuria, causing dark urine. Serum creatinine kinase (CK) enzyme levels are usually markedly elevated. Severity can range from muscle enzyme elevation in the serum of an otherwise asymptomatic patient to extremely…
The Problem with Peer Review
I should have paid more attention in medical school. If I had, I might have remembered enough about basic pathophysiology to know why everyone was suddenly pulling their patients off of lisinopril. For those of you who need a quick primer: When the pressure in the renal artery drops, the kidney secretes renin. Working together,…
Abaloparatide vs. Alendronate for Osteoporosis
In a clinical trial, researchers compared the efficacy of abaloparatide with alendronate in reducing the risk of fracture among postmenopausal women with osteoporosis. The findings suggest initial treatment with abaloparatide may result in greater vertebral fracture reduction than alendronate…
Lupus Nephritis: Understanding the Paradigm for Treatment
ACR BEYOND LIVE—Among patients with systemic lupus erythematosus (SLE), lupus nephritis remains one of the leading causes of mortality, and patients with both SLE and end-stage renal disease demonstrate standardized mortality ratios higher than 60 times that of patients with SLE who have normal kidney function.1 Although the ACR Guidelines for Screening, Treatment, and Management…
