Research project moves one step closer to personalized treatment of rheumatic diseases

When a patient is diagnosed with rheumatoid arthritis, psoriatic arthritis or spondyloarthritis, prescribing the correct type of medicine is a case of trial and error. It is simply not possible to predict which medication will work for the individual patient, and it is therefore a matter of trying the different treatment options: glucocorticoids, low dose chemotherapeutic drugs or newer biological drugs. Until now! A new research project from Aarhus University and Aarhus University Hospital in Denmark suggest that it is the composition of cells in the joint of the individual patient which determines whether the medicine is effective or not. The researcher behind the study, published in the journal of the American College of Rheumatology ( ACR Open ), is medical doctor and PhD Tue Wenzel Kragstrup from the Department of Biomedicine at Aarhus University and the Department of Rheumatology at Aarhus University Hospital. So far, we've examined the effect of nine drugs in three different in vitro models. We can see that the effect of a given drug depends on the cell compositions. This leads us to hope that the immunological cells and inflammatory signaling molecules in the joint of each individual patient will be able to predict the most effective treatment." Tue Wenzel Kragstrup, Department of Biomedicine at Aarhus University The study's in vitro models consist of cell cultures isolated from joint fluids aspirated from the joints of patients with severe arthritis as part of the treatment at Aarhus University Hospital. The researchers then used the diseased cells from the joint fluid to examine the effects of different types of medicine, explains Tue Wenzel Kragstrup's colleague, Ph.D. student Morten Aagaard Nielsen from the Department og Biomedicine, who is first author of the article. "As far as we know, this is the first description of a direct association between the composition of the immune system cells and the effect of medication," Morten Aagaard Nielsen says.
