Treatment of paediatric ulcerative colitis (UC) unresponsive to conventional treatment constitutes a challenge. The finding of new secure, steroid-sparing and long acting treatments for these cases are mandatory. We report our experience with a long-term therapeutic strategy with Adacolumn in a chronically active paediatric UC patient (9 year-old boy) with the aim of achieving stabilization and ameliorating symptoms, permitting a successful switch to AZA monotherapy. These two aspects have been achieved without reappearance of rectal bleeding after oral mesalamine suppression. But the most interesting and promising finding is the confirmation of GMA apheresis effect on mucosal healing after prolonged treatment: maintenance treatment with Adacolumn has been effective in achieving a complete endoscopic and histological remission.

This case shows the utility of prolonged Adacolumn treatment in chronically active UC patients.

Granulocytapheresis (GCAP) has produced efficacy in adult patients with ulcerative colitis (UC) by adsorbing activated granulocytes and monocytes/macrophages. We retrospectively investigated efficacy and safety of GCAP in pediatric patients with active UC. Twelve steroid-refractory children (12.2 +/- 3.1 years old) were treated with GCAP, one session/week for 5-10 consecutive weeks. In 8 patients, clinical symptoms improved after two GCAP sessions. Normal body temperature, stool frequency, and disappearance of blood in stool were seen after 24.3 +/- 11.5 days. The endoscopic grade improved from 2.6 +/- 0.3 to 0.4 +/- 0.2. One patient who initially responded, developed bloody diarrhea later and 2 cases remained unchanged. The dose of steroid was tapered during GCAP therapy by 50%. No serious adverse effects were noted. Four of 8 cases relapsed 3.5 +/- 2.2 months after the last GCAP while on maintenance therapy, the other 4 were in remission up to 22.8 +/- 18.1 months. In conclusion, GCAP appears to be effective and well tolerated in children with steroid-refractory UC.
