Single-needle (SN) apheresis may be safe and effective and may reduce patient burden during UC treatment. Nevertheless, further comparative studies are needed.

GMA was an effective treatment for corticosteroid-naïve patients and the efficacy sustained longer in those not receiving immunomodulators during GMA. GMA fulfills the notion that apheresis is to induce disease remission by removing from the body factors known to perpetuate disease. In therapeutic settings, these findings should help better decision making and avoid futile use of medical resources.

The effect of GMA with concomitant PSL (Prednisolone) and that of GMA without PSL were not different, and GMA was effective irrespective of PSL administration. The present study showed that GMA had efficacy and led many UC patients treated by PSL to be steroid free with no safety concern in the real world, although there is the possibility of recruitment bias due to the retrospective nature of the study.

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.
