Resolution of inflammatory colitis with pegfilgrastim treatment in a case of severe congenital neutropenia due to glucose 6 phosphatase catalytic subunit-3 deficiency

J Pediatr Hematol Oncol. 2014 Jul;36(5):e316-8. doi: 10.1097/MPH.0000000000000079.


Glucose 6 phosphatase catalytic subunit-3 (G6PC3) deficiency is a heterogenous disorder characterized by severe congenital neutropenia and a variety of extrahematopoietic manifestations. Inflammatory bowel disease like colitis is an uncommon complication of G6PC3 deficiency, described only in adolescent and adults. Herein, we describe inflammatory colitis in a 10-year-old girl with severe congenital neutropenia due to G6PC3 deficiency while she was on a high-dose filgrastim. Switching from filgrastim to (pegylated filgrastim) Pegfilgrastim led to rapid resolution of colitis, weight gain, and decreased infections. Pegfilgrastim seems to be a better remedy for treatment of G6PC3 deficiency complicated with inflammatory bowel disease.
