ABSTRACT
INTRODUCTION: Granulocyte and monocyte adsorption apheresis (GMA) is usually performed weekly for refractory skin diseases, such as generalized pustular psoriasis and psoriatic arthritis (PsA). METHODS: Four patients with PsA who were refractory to previous treatments were enrolled. They received five or ten sessions of GMA. We assessed the clinical conditions of each patient and laboratory findings before and after GMA. RESULTS: GMA was effective in plaque-type skin eruptions in all four patients with PsA. It was also effective in joint symptoms in three patients with PsA with mild symptoms, but was ineffective in one patient with severe joint symptoms. CONCLUSION: GMA may be recommended to PsA patients with skin eruptions and mild joint symptoms.
