Rheumatoid factor (RF) is one of the best known serological markers in rheumatology – development of the test dates back into the 1940ies. Since this time the toolkit of serological diagnostic tests for rheumatoid arthritis (RA) has been complemented by the more specific anti-citrullinated protein antibody (ACPA) tests. However, none of the various ACPA tests has completly replaced RF until now.
The jigsaw puzzle of rheumatoid arthritis classification
In contrast, the significance of RF has been further substantiated with the definition of the 2010 ACR criteria for classification of RA. Moreover, recent studies have shown the potential of RF as a contributor to disease pathogenesis.
In rheumatoid arthritis, standard heart disease risk tools underrate danger!
Patients suffering from rheumatoid arthritis, or RA for short, are at higher risk for heart disease. Among experts that’s a matter of common knowledge (fortunately and increasingly that is basic knowledge among patients, too!).

On a less positive note, commonly used heart disease risk assessment tools seem to be inadequate for estimating the risk of cardiovascular disease danger faced by RA patients. That is what a brand-new study found.
In this blog article I summarise the main results of the research done at Mayo Clinic in Rochester, Minnesota (USA). The study is entitled Usefulness of Risk Scores to Estimate the Risk of Cardiovascular Disease in Patients With Rheumatoid Arthritis, and it has been published online on 20th April 2012 in The American Journal of Cardiology.
Heart disease risk in RA: More accurate assessment tools needed
The study estimated the accuracy of the Framingham and Reynolds risk scores, two tools commonly used by physicians for assessing patients’ heart disease danger. The scientists found that these two assessment tools substantially underrated cardiovascular disease danger both in women and men suffering from rheumatoid arthritis. In particular, that happens in older patients. Interestingly enough, it also happens in people who test positive for rheumatoid factors. (more…)
Research Update: Prognosis of Outcomes for Rheumatoid Arthritis – What are the Risk Factors?
In the past, it has only been possible to explain some of the joint damage caused by rheumatoid arthritis (RA) based on known risk factors. In order to improve treatment for RA, future approaches to treatment will increasingly need to be tailored to individual patients and individually configured.
Personalized medicine in RA treatment
The goal is to develop individual treatments tailored to the needs of the individual patient, “personalized medicine” for rheumatoid arthritis diagnosis and treament (for more on the subject of personalized medicine, refer to the background article Early Detection and Personalised Medicine – What Biomarkers Tell Us on our rheumachec homepage).

Duroux-Richard I, Jorgensen C, Apparailly F. miRNAs and rheumatoid arthritis – promising novel biomarkers. Swiss Med Wkly. 2011 Mar 18;141:w13175 – doi: 10.4414/smw.2011.13175 – Free full text available! – Today, the most challenging issue in the field of rheumatoid arthritis is the identification of biomarkers for early disease diagnosis and for prediction drug response. micro(mi)-RNAs certainly represent an realistic option for optimal diagnosis an disease treatment.

According to a recently published study anti-MCV could be a better test for diagnosing RA than anti-CCP2
Rapid intensive treatment may prevent patients with rheumatoid arthritis (RA) from developing severe health damages and improve their state of health and quality of life. Therefore, early reliable diagnosis is a prerequisite. At present, the most helpful biomarkers to achieve this goal are antibodies against citrullinated proteins (ACPA) that can be detected in the blood of RA patients. (more…)
ACPA in rheumatism diagnostics: new and highly promising biomarkers for rheumatoid arthritis
The diagnosis and treatment of rheumatoid arthritis (RA) have made tremendous progress in the last few years. Experts are even suggesting that a paradigm shift has occurred in the field of rheumatology.
According to rheumatologists, this radical change can be seen in the completely new rheumatoid arthritis medications that have resulted in entirely new treatment options. Again and again, the paradigm shift in rheumatology is attributed to the new possibilities in rheumatoid arthritis diagnostics. Modern RA diagnostics are said to make it increasingly possible for rheumatologists to objectively determine the activity level of RA and thus to predict the progression of this autoimmune disease.

Our Point-of-Care-Test rheumachec for Diagnosing Rheumatoid Arthritis – a Highly Accessed Research Article in Arthritis Research & Therapy!
Several days ago, a colleague pointed out to me a publication in the journal Arthritis Research & Therapy that came about largely through collaboration with scientists at ORGENTEC Diagnostika. Needless to say that this article was already familiar to me – already before its initial online publication in the summer of this year, I had read excerpts from it and extensively discussed the work and the results of this evaluation study with co-workers and clients.

Biomarkers are the key to prevention and early detection of disease …
… of this I am convinced. And I am firmly convinced that laboratory diagnostics and the use of biomarkers will have a critical effect on the medicine of tomorrow.
Why am I so sure of this? It has already been demonstrated that biomarkers can be used to optimize treatment for individual patients with diabetes. In the future, individualized medicine (also sometimes called “personalized medicine”) will not only significantly increase the efficiency of treatment; it will also greatly improve prevention and early detection. Today it is already possible to carry out a diagnosis in the symptom-free phase of a disease by using biomarkers. This is of great benefit to the patients who receive early and targeted treatment.

In the September issues of their journals Arthritis and Rheumatism and Annals of the Rheumatic Diseases the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) present a new set of criteria for the classification of rheumatoid arthritis (RA).
Why do wee need “new” criteria for the classification of RA?
The 1987 ACR criteria have been criticised for their lack of sensitivity, especially in early disease. They rather describe the symptoms of fully developed late-stage RA. During the past decade, RA treatment has undergone dramatic changes (more…)
New ACR/EULAR 2010 Classification Criteria for Rheumatoid Arthritis (RA)
European and American rheumatologists have established new criteria for the classification of rheumatoid arthritis (RA). The Revised Classification Criteria for Rheumatoid Arthritis will appear in the September issue of Arthritis & Rheumatism; they can also be viewed online or as a free download at the ACR homepage (accessed 23/08/2010).
