The disease often causes swelling of the fingers and toes. It gets its name from the link between this type of arthritis and a skin condition called psoriasis, which causes redness and scaling. Being able to measure disease activity in psoriatic arthritis allows doctors to see how well medicines are working. There are many different disease activity scores available that look at different parameters. The Disease Activity Index for Psoriatic Arthritis (also known as DAPSA) is one of these and has been developed to include a series of key disease elements. High disease activity generally means that a person\u2019s disease is not well controlled, and may be causing joint damage and pain. Being in low disease activity or remission (no signs of symptoms) is the goal of treatment for psoriatic arthritis.<!--more--><\/p>\n<p><strong>WHAT DID THE AUTHORS HOPE TO FIND?<\/strong><br \/>\nThe authors wanted to be able to work out how they could use the DAPSA to say when people had achieved certain states (such as remission), or to say whether their treatment was working.<\/p>\n<p><strong>WHO WAS STUDIED?<\/strong><br \/>\nThe study looked at 30 people with psoriatic arthritis, as well as data from 425 patients in three trials: the ADEPT, IMPACT, and GO-REVEAL studies, which investigated the efficacy of three different tumour necrosis factor inhibitors called adalimumab, infliximab and golimumab in patients with psoriatic arthritis who had not seen an improvement in their disease with traditional treatments known as disease-modifying antirheumatic drugs (DMARDs) or non-steroidal anti-inflammatory drugs (NSAIDs).<\/p>\n<p><strong>HOW WAS THE STUDY CONDUCTED?<\/strong><br \/>\nThe authors used patient profiles from an observational database. They then carried out a survey among doctors who were experts in joint diseases to sort these 30 patients into one of four groups (remission, low, moderate, or high disease activity) based on how many swollen or tender joints they had, their level of pain, and laboratory measurements of markers in their blood that indicate inflammation. Based on the distribution of the DAPSA results they then defined the cut-offs between groups. The authors then repeated the test without certain elements, and checked against published study data to see how well the DAPSA results agreed with other disease activity states used.<\/p>\n<p><strong>WHAT WERE THE MAIN FINDINGS OF THE STUDY?<\/strong><br \/>\nThe authors found that the DAPSA is a good tool to use for assessing disease activity in psoriatic arthritis, and that it agrees well with other scoring systems. The DAPSA scores were very different for the people in each of the four groups. The authors conclude that DAPSA scores of 4 or less mean a person is in remission. Scores of 4\u201314 suggest low disease activity, 14\u201328 for medium disease activity, and more than 28 means a person has high disease activity. ARE THESE FINDINGS NEW? Yes, up until now definitions of disease activity states and therapeutic response have been missing for the DAPSA.<\/p>\n<p><strong>WHAT ARE THE LIMITATIONS OF THE STUDY?<\/strong><br \/>\nOne limitation is that the study used a small number of patient profiles. However, the authors compared the information with real-life patients from the ADEPT, IMPACT, and GO-REVEAL studies and found similar patterns, which means that the results are reliable, even for this small set of patients.<\/p>\n<p><strong>WHAT DO THE AUTHORS PLAN ON DOING WITH THIS INFORMATION?<\/strong><br \/>\nThe authors plan to repeat the test in large-scale observational studies of people with psoriatic arthritis.<\/p>\n<p><strong>WHAT DOES THIS MEAN FOR ME?<\/strong><br \/>\nIf you have psoriatic arthritis, tools like the DAPSA may help your doctor to assess whether your treatment is working. The DAPSA may also help them to target remission or low disease activity by using a treat-to-target approach.<\/p>\n<p><strong>Disclaimer:<\/strong> This is a summary of a scientific article written by a medical professional (\u201cthe Original Article\u201d).
