Granulocyte and monocyte adsorptive apheresis (GMA) is occasionally introduced as an alternative combination therapy after loss of response to biologics in ulcerative colitis (UC) patients. However, there have been no reports of the concomitant use of vedolizumab (VDZ) and GMA for the initial induction of UC. A 20-year-old man with refractory UC was admitted for recrudescence. VDZ monotherapy had previously been introduced but was ineffective. Therefore, he received scheduled combination of VDZ and GMA and achieved clinical remission. The combination of two different approaches to inhibit the migration of leukocytes into the inflamed tissue led to satisfactory clinical outcomes.

We have reported the first case of using GMA in combination with vedolizumab in a patient with active, steroid-dependent UC with an inadequate response to vedolizumab and previous biologic failure to adalimumab and infliximab, achieving remission in the follow-up. It is believed that the primary consequence of GMA therapy is a selective depletion of certain subsets of myeloid leucocytes, the most relevant of which could be the CD14+ CD16+ DR++phenotype, also known as the proinflammatory monocytes.This selective depletion of circulating leucocytes could enhance the reduction of gut trafficking of leucocytes induced by vedolizumab and modify the concentration of proinflammatory cytokines. In this clinical context, GMA therapy could be a safe, on pharmacological treatment that could help to reduce the inflammatory load, thereby enhancing the effect of biologic drugs.
