A recent study in mice examined the role of adenosine A2A receptors in joint health. Researchers specifically found that as extracellular levels of adenosine fall, individuals may become at risk for osteoarthritis…

Effect of Diet & Sodium Intake on Serum Uric Acid
Serum uric acid (UA) is an important factor in the causal pathway for gout. It has also been implicated as a potential risk factor and/or mediator of cardiovascular disease outcomes and mortality in a large number of observational studies. Although many of the clinical trials targeting serum UA reduction have focused on pharmacologic interventions, diet…
Rheumatology Coding Corner Question: Joint Injection with Ultrasound Guidance, No Office Visit
A 66-year-old male patient presents to the office with right knee pain. He was in the office two weeks prior for a follow-up visit of his primary osteoarthritis. He received an injection of hyaluronate sodium in his right knee four months before and states that his knee felt like new. He states that everything was…
When Rheumatologists Are a Patient’s Second or Third Choice for Medical Opinion
Outside Exam Room No. 5, the chart rack was empty, so I assumed my new consult was late. Just in case, I looked back over my shoulder as I passed by the partially open door and glimpsed the lower half of a woman holding a three-ringed binder on her lap. I squinted and took a…
Biochemical Insights into Progeria Syndrome Identify Bisphosphonates, Statins as Possible Candidate Drugs to Halt Aging
Can We Stay Forever Young? May your heart always be joyful And may your song always be sung May you stay forever young Forever Young —Bob Dylan Beneath the rubric of orphan diseases reside some rare conditions and others that are extraordinarily uncommon. These are the diseases that most physicians either never to get to…
Researchers Hone in on Defect in Autophagy that May Underlie Lupus
New research investigates the role of autophagy, specifically the cell digestion process called LC3-associated phagocytosis (LAP), in inflammation and the pathology of systemic lupus erythematosus (SLE). Researchers found that defects in this process result in failure to digest dying cells, which increases inflammatory cytokine production and results in SLE-like disease in mice. Further exposure to dying cells accelerated disease development…
Patients with RA Who Respond to Treatment Experience Increased Cholesterol
New research confirms that patients with rheumatoid arthritis who respond to treatment experience an increase in cholesterol levels, including total cholesterol, LDL-C and HDL-C levels. However, the use of triple therapy may be important for understanding this association and mitigating its risk…
Autoantibodies in Pregnant Woman May Put Infant at Risk for Neonatal Lupus Erythematosus
A recent case study revealed that an infant from a donor egg developed neonatal lupus erythematosus (NLE) and a congenital heart block, which may have been due to the presence of antibodies to Ro and La in the birth mother—not the genetic mother. The results suggest that a gestational mother with a history of autoimmune disease is sufficient to trigger the pathology of NLE…
Patients with Lupus: Plasmacytoid Dendritic Cells Fail to Induce Regulatory B Cells
A recent study found that plasmacytoid dentricitic cells (pDCs) control the differentiation of immature B cells into regulatory B (Breg) cells or plasmablast, depending on the concentration of IFNα. For patients with SLE, researchers found that immune regulatory feedback between pDCs and Breg cells is dysfunctional, with the exception of patients who respond to rituximab…
2015 ACR/ARHP Annual Meeting: Treatments for Transthyretin-Related Amyloidosis Generate Interest from Researchers, Pharmaceuticals
SAN FRANCISCO—Treatment for transthyretin-related amyloidosis (ATTR) is generating more interest from academic researchers and the pharmaceutical industry, with encouraging early results using a multi-pronged therapeutic approach, a researcher said at a review course held before the 2015 ACR/ARHP Annual Meeting. Amyloidoses are a rare and potentially deadly family of diseases in which misfolded protein builds…
