Psoriatic arthritis has been recognized as an auto-immune disease in which there is participation of the cytokine-producing T cells (tumor necrosis factor-alpha). Infliximab is a monoclonal antibody that binds to and inactivates tumor necrosis factor-alpha. Reported is a case of severe psoriatic arthritis which was unresponsive to multiple systemic therapies and treated with an intravenous infusion of infliximab, 5mg/Kg in three hours, in weeks 0,2,6 and 14, associated with a low dose of methotrexate, with an excellent therapeutical response.
