Bring the feet when diagnosing, treating rheumatoid arthritis

Rheumatoid Arthritis (RA) is a painful form of rheumatism which is characterized by infections in the joints and soft tissues. A method known as DAS-28 is often used to gauge the seriousness of the condition. DAS stands for Disease Activity Score. The method involves examining 28 joints in the upper body and checking the knees for pain and swelling. The results are weighted together with the results of laboratory tests and the patient's pain score, which ultimately gives a figure that indicates how active the disease is.

In practice, the feet and ankles of RA patients receive only limited attention. However, problems with the feet and ankles can significantly impact on the patients' mobility, and thus their social lives too. As a result of her research at the University of Twente, rheumatologist Hetty Baan makes the case for the use of a DAS 44, which would also include the feet and ankles. This could improve treatment and prevent unnecessary infections and damage.

Baan also sees the added value in the more frequent use of MRI scans for the purpose of diagnosis and treatment. This method can detect not only damage and infections in the joints, but also any abnormalities in the tendons. In Baan's research, 70 percent of the patients were suffering from abnormal tendons. Baan says that more research is needed to look at how the diagnosis and treatment of foot and ankle problems can be improved further, however.

Hetty Baan carried out her research among 30 outpatients being treated for RA. She investigated whether and in what order they were experiencing problems with their feet. The patients underwent clinical tests and completed questionnaires, a gait analysis was conducted and various forms of medical imaging were carried out (ultra-sound imaging, x-rays and MRI scans).
