Our case and the case of Kanekura et al⁸ suggest that circulating leukocytes may play an important role in the pathogenesis of PG and that GCAP in combination with corticosteroids may be a promising strategy for intractable PG. Furthermore, as has been the case for active UC, GCAP may be a choice for severe pouchitis. An accumulation of data with respect to the effect of GCAP on pouchitis seems to be warranted.

We concluded that combined therapy of GCAP or LCAP and corticosteroids is effective for the treatment of RPGN and lung hemorrhage due to microscopic polyangiitis.
