Granulocyte and monocyte adsorption apheresis (GMA) is an extracorporeal circulation therapy that removes activated granulocytes and monocytes, which can be easily introduced in clinics and hospitals where hemodialysis is performed. Its safety profile  allows for its administration without screening and for its concomitant use with other therapies, indicating that GMA can be a good additional option for GPP treatment. However, the evidence for its efficacy and safety is limited because of the rarity of GPP. Furthermore, its immediate impact on GPP has not been assessed yet. Therefore, we report our real-world experience of 14 patients with GPP treated with GMA after systemic treatment.GMA can be administered with other systemic therapies, including biologics and conventional therapy (objective A). Furthermore, its good safety profile allows GMA administration to a wide range of patients, including elderly patients and those with complications, possible active infection, or malignancy (objectives B and C). Moreover, our study revealed an immediate significant improvement in BT, accompanied by slight decreases in the WBC count and CRP level, indicating that GMA contributes to the rapid suppression of acute inflammation in patients with GPP.
