Adsorptive granulocyte and monocyte apheresis (GMA) is an extracorporeal treatment that selectively removes activated myeloid lineage leukocytes from peripheral blood. This technique consists of a column with cellulose acetate beads as absorptive leukocytapheresis carriers, and was initially used to treat ulcerative colitis. A literature search was conducted to extract recently published studies about the clinical efficacy of GMA in patients with different skin disorders, reporting information on demographics, clinical symptoms, treatment and clinical course. Dermatological diseases, in which GMA has been performed, include generalized pustular psoriasis, pyoderma gangrenosum, palmoplantar pustular psoriasis, Behcet’s disease, Sweet’s syndrome, adult-onset Still’s disease, impetigo herpetiformis, reactive arthritis, acne and hidradenitis suppurativa syndrome, cutaneous allergic vasculitis and systemic lupus erythematosus. In most patients, GMA was started after the failure of conventional therapeutic options and it was helpful in the majority of cases. Based on the information summarized, GMA could be considered a valid non-pharmacological treatment option for patients with several dermatological conditions, which are difficult to treat with other pharmacological preparations.

Granulocyte and monocyte adsorption apheresis for cutaneous allergic vasculitis
Cutaneous allergic vasculitis (CAV) is characterized clinically by purpuric patches with secondary ulcerations, and histologically by leukocytoclastic vasculitis with neutrophil infiltrates. Granulocyte and monocyte adsorption apheresis (GCAP) is an extracorporeal apheresis instrument using a column containing cellulose acetate beads designed to remove pathogenic granulocytes. Here we report our assessment of the efficacy of GCAP for recurrent leg ulcers in a 49-year-old woman with CAV. She underwent five GCAP treatments at one-week intervals. In each treatment session, 1800 mL of blood was processed. Her leg ulcers responded well and her white blood cell and neutrophil counts and the expression level of CD11b/CD18, a marker for activated neutrophils, on her peripheral neutrophils were reduced from 7500/microL to 6500/microL, 4350/microL to 3315/microL, and 64.9 MFI (mean fluorescence intensity) to 27.0 MFI (normal controls: 10.5 +/- 1.2 MFI) by GCAP, respectively. These results suggest that GCAP is useful for skin disorders with leucocytoclastic vasculitis.
