Keep up-to-date on the latest rheumatoid arthritis (RA) research with our brief research summaries.
Vitamin D Deficiency Associated with Neuropathic Pain
People with RA who suffer from neuropathic pain – or, understandably, are trying to avoid it – may do well to have their vitamin D levels checked. A study examined neuropathic pain indicators as well as blood samples of 93 patients with RA. The researchers found the prevalence of neuropathic pain was almost six times higher in patients with serum vitamin D levels below 20 nanograms per milliliter (ng/mL) than in patients with vitamin D levels ≥ 30 ng/mL. Anything below 20 ng/mL is considered a deficiency.

Children born to mothers with rheumatoid arthritis (RA) appear to have an increased risk of RA and two other chronic health problems, according to a study published online recently in Arthritis Care & Research, although the number of children affected is still small. The findings are based on data for all children born in Denmark over a nearly 25-year period.

We asked our readers and followers this question: “What was the most unexpected side effect of your rheumatoid arthritis or RA treatment?” Here are their answers.

People with rheumatoid arthritis (RA) have roughly twice the risk of healthy older adults of developing shingles, a virus related to chickenpox that causes pain and a blistering rash.
Most adults have been exposed to varicella zoster virus, which causes chickenpox. This virus is never completely cleared from our bodies, but lies quietly in spinal nerve cells. If it’s reactivated it causes shingles, explains rheumatologist Jeffrey Curtis, MD, professor medicine at the University of Alabama at Birmingham. The reactivated virus is called herpes zoster or shingles.

Thanks to earlier diagnosis and more effective treatments, joint deformities in people with rheumatoid arthritis (RA) are becoming less frequent and severe.
What Causes Joint Deformities in RA?
In a joint affected by RA, inflammatory cells of the immune system gather in the lining of the joint (called synovium), forming a fibrous layer of abnormal tissue (called pannus). The pannus releases substances that quicken bone erosion, cartilage destruction and damage to the surrounding ligaments. The involved joints lose their shape and alignment, resulting in deformities. Severe deformities lead to loss of joint function and the need for joint replacement surgery.

Generally, patients with rheumatoid arthritis (RA) have higher levels of inflammation in their bodies, which can affect other organs and tissues besides the joints. In fact, people with RA have up to twice the risk of heart disease and development of heart failure (especially if they test positive for rheumatoid factor, or RF) than the general population, according to a 2013 Mayo Clinic study published in the American Heart Journal.

Early studies show an implanted device that sends electrical signals to the brain via the vagus nerve has potential as a new therapy for rheumatoid arthritis (RA).

The fatigue that often accompanies rheumatoid arthritis (RA) can be as distressing and disabling as the pain – and often harder to treat. RA-related fatigue has been associated with molecules called cytokines that promote inflammation, such as tumor necrosis factor (TNF), and the use of biologics that block TNF have been shown to somewhat reduce fatigue. But a new study published online in the journal Rheumatology quantifies just how stubborn RA-related fatigue is – even when the disease itself is well controlled with an anti-TNF medication – and characterizes which patients are most likely to beat it.

If you have a few – or a lot – of pounds to lose, you know that carrying excess weight around can stress your painful or fragile joints. But research shows that the mechanical effects of weight are just part of the problem.
Fat itself releases chemicals including tumor necrosis factor-α (TNF-α) and interleukin-1 (IL-1) that promote inflammation. These chemicals may not only increase the risk of developing some forms of arthritis, but they may also increase arthritis severity or make it harder to control.
In fact a study presented at the 2015 annual meeting of the American College of Rheumatology found that for people with early rheumatoid arthritis (RA), being overweight or obese can reduce the chance of achieving sustained remission.

People with rheumatoid arthritis (RA) are likely to have a much better quality of life today than they did two decades ago. Researchers in the Netherlands observed more than 1,100 patients diagnosed with RA between 1990 and 2011. They attribute the gains to earlier diagnosis, more aggressive medications and a greater emphasis on overall well-being. Their findings were published in Arthritis Care & Research in 2014.
Lead author Cecile Overman, a postdoctoral researcher at Utrecht University in the Netherlands, says she and her colleagues wanted to determine if improved treatments over the last 20 years led to better physical and psychological health for RA patients.
