Dactylitis in a Patient with Psoriatic Arthritis Treated with Infliximab / 대한내과학회지

ABSTRACT

Dactylitis is a hallmark feature of psoriatic arthritis. It is usually managed with non-steroidal anti-inflammatory drugs and oral corticosteroids. Some cases have been treated successfully with intravenous corticosteroids or some disease-modifying antirheumatic drugs. Recently, inflximab has been reported as an effective treatment for dactylitis that is resistant to conventional treatment. This report describes a 37-year-old man with psoriatic arthritis who had multiple dactylitis on both thumbs and great toes. He was resistant to conventional treatment but was effectively treated with infliximab. This report highlights the effectiveness of infliximab for dactylitis, and the usefulness of blood pool imaging from bone scans as a method for determining treatment response.
