Granulocyte and monocyte/macrophage apheresis for the treatment of immune-mediated inflammatory arthropathies: case reports.

Drug therapy of immune-mediated inflammatory arthropathies is not always satisfactory, and there is a risk of adverse events. Granulocyte and monocyte/macrophage apheresis (GMA) is a non-pharmacological therapeutic option that is beneficial and very well tolerated. GMA involves passing blood through a column with cellulose acetate beads to remove increased and activated myeloid lineage cells and improve the cytokine profile. The technique reduces pain and inflammation. We present four clinical reports that illustrate the clinical uses of GMA with the medical device Adacolumn® in patients with different backgrounds and immune-mediated inflammatory arthritis. The results were positive, and no adverse events were reported.
