Stress and the Risk of Incident Inflammatory Arthritis

A prospective analysis of newly diagnosed, inflammatory arthritis (IA) patients suggests that perceived distress (stress) increases the odds of incident IA.

Data was drawn from the Studies of the Etiologies of Rheumatoid Arthritis (SERA) dataset that include people without IA who were recruited if they were a first degree relative of a RA proband or screened positive for anti‐cyclic citrullinated peptide autoantibody (ACPA). IA was defined as having at least 1 joint consistent with rheumatoid arthritis (RA)‐like synovitis based on exam. Perceived stress was assessed using the Perceived Stress Scale‐14 (PSS) in which scores can range from 0 to 56 and a higher score indicates greater perceived stress. 

In this cohort the mean total PSS score was 20.4.

A one‐point increase in the perceived distress score was significantly associated with a 10 percent increase in the risk of IA (adjusted HR: 1.10; 95%CI: 1.02, 1.19).

Total PSS and self‐efficacy were not associated with IA risk (adjusted HR: 1.05 (95%CI: 0.99, 1.10) and 1.04 (95%CI: 0.91, 1.18), respectively.

More studies are needed to confirm whether stress (a modifiable risk factor?) is associated with an increased risk of inflammatory arthritis.

MRI in the Diagnosis and Management of Polymyalgia Rheumatica

Polymyalgia rheumatica (PMR) is a common condition seen by both primary care and in the rheumatology office.

Many cases of PMR are extremely straightforward for a trained rheumatologist — with easy to recognize joint pain and stiffness in the shoulder and hip girdles, elevated inflammatory markers, and a rapid response to moderate doses of prednisone (15-20mg).

It has been a wonderful year for autoinflammatory diseases at the ACR Annual Meeting.

I attended my first ACR Annual Meeting in 2011 in Chicago. In that meeting, there were 29 abstracts on autoinflammatory diseases and there were no sessions exclusively focusing on that topic*.
