Early Treatment Equals Better Results for Rheumatoid Arthritis
Alan Mozes writing for Healthday reported treating rheumatoid arthritis early may make for better outcomes, a new study suggests.
Patients who were treated within six months of developing the first signs of the autoimmune disease did better in the long run and were less likely to suffer early death, British researchers found.
The findings stem from an analysis of more than 600 patients who were initially diagnosed with rheumatoid arthritis (RA) between 1990 and 1994. They were tracked for over 20 years.
Over the study time frame, investigators assessed key symptoms of RA, such as swollen and/or tender joints, and indications of disability. All deaths were also noted.
The research team found that patients who started treatment for RA within the first half-year after the first symptoms surfaced tended to have no greater levels of disability over a 20-year period than patients who required no treatment.
Comment: It is critical to be aggressive with this disease.

Pedometers increase activity and decrease fatigue in rheumatoid arthritis patients
Wiley writing for Eureka Alert reported providing pedometers, with and without providing step targets, to individuals with rheumatoid arthritis increased activity levels and decreased fatigue in a recent study.
In control patients who did not receive pedometers, average daily steps declined and there was no significant change in fatigue.The findings are important because fatigue can have a significant impact on quality of life for individuals with rheumatoid arthritis, but effective and feasible treatments are limited.
“Because rheumatoid arthritis medications have only small effects on fatigue, it’s important for patients to have other ways to manage their fatigue,” said Dr. Patricia Katz, lead author of the Arthritis Care & Research study. “These results suggest that something as simple as increasing physical activity by walking can help.”
Study Shows Potential for Early Diagnosis of Arthritis
Pat Anson writing for Pain News Network reported a new study by British researchers has demonstrated the potential for an experimental blood test that can diagnose arthritis in its earliest stages. Such a test could lead to earlier treatment of osteoarthritis (OA) and rheumatoid arthritis (RA), years before joint damage and physical symptoms begin.
Researchers at Warwick Medical School recruited 225 people with early or advanced OA, RA or another inflammatory joint disease, along with a control group of healthy volunteers with no joint problems. Their blood and fluid from affected knee joints were then analyzed with mass spectrometry.
The test found patterns in blood plasma amino acids that were damaged by oxygen, nitrogen and sugar molecules. The damage was highest in the blood samples of patients with OA or RA, and markedly lower in the blood of healthy volunteers — giving researchers identifiable biomarkers that could be used for an early diagnosis.
“This is a big step forward for early-stage detection of arthritis that will help start treatment early and prevent painful and debilitating disease,” said Naila Rabbani, PhD, of Warwick Medical School. “Damage to proteins in the arthritic joint have been known for many years but this is the first time it has been exploited for early-stage diagnosis.
“For the first time we measured small fragments from damaged proteins that leak from the joint into blood. The combination of changes in oxidised, nitrated and sugar-modified amino acids in blood enabled early stage detection and classification of arthritis – osteoarthritis, rheumatoid arthritis or other self-resolving inflammatory joint disease.”

Rheumatoid Arthritis Effectively Diagnosed And Treated With Biodegradable Nanoparticles In Early Study
Dr. Patricia Inacio writing in Rheumatoid Arthritis News reported biodegradable polymer nanoparticles (BNPs), tiny particles made of a biodegradable polymer, appear to be quite useful for the early detection and for long-term, effective treatment of rheumatoid arthritis (RA) with minimal side effects, according to a study presented at the recent. These particles, once coated with a molecule that specifically targets inflamed joint tissues, ensure a high degree of efficacy in delivering both diagnostic probes and drugs to arthritic joints.
Dr. Paolo Macor, the study’s lead investigator from the Department of Life Sciences, University of Trieste, Italy said “There is a need to develop a new tool to enable early diagnosis, and also to develop tissue-specific agents able to reduce systemic side effects. This would increase the potency of drugs with lower doses, and also potentially reduce the cost of treatment,” Dr. Macor said.
Comment: Exciting and I look forward to hearing more.
A pair of recent studies look in an interesting place to find commonality among rheumatoid arthritis sufferers:
Ryan Black writing for MD reported on a study published in Genome Medicine from the Mayo clinic. Veena Taneja, Ph D of the Mayo Clinic’s Center for Immunized Medicine said they sought to find a biomarker in the form of gut microbiota. Examining fecal samples of (human) RA patients and their first-degree relatives, the researchers noticed that an abundance of collinsella in the gut was linked to increased RA symptoms.
To test this, they administered collinsella to “humanized” mice, and found that “Mice given [Collinsella aerofaciens] developed arthritis with increased incidence and severity compared with non-treated mice (100 % incidence in treated vs 62.5 % in untreated, P = 0.068).” Their findings indicate that collinsella may be a predictive biomarker for RA in humans.
