Stepwise diet management in pediatric gastrointestinal graft versus host disease

Area of Science:

• Gastroenterology
• Hematology
• Pediatric Oncology

Background:

• Gastrointestinal graft-versus-host disease (GI-GVHD) is a significant complication following stem-cell transplantation (SCT).
• Gut injury during pre-SCT conditioning therapy initiates inflammatory processes crucial to GI-GVHD development.

Purpose of the Study:

• To evaluate the efficacy of a stepwise diet management strategy for acute GI-GVHD in pediatric SCT patients.
• To assess the impact of nutritional support on GI-GVHD recovery and patient outcomes.

Main Methods:

• Retrospective review of medical records for pediatric patients undergoing SCT between April 2010 and June 2013.
• Implementation of a stepwise upgrade diet including total parenteral nutrition (TPN) and minimal enteral nutrition (MEN) for patients with grade III-IV acute GI-GVHD.
• MEN consisted of 1-2 ml/kg/day of standard pediatric enteral formula or special meat soup.

Main Results:

• Seven out of 105 SCT patients developed grade III-IV acute GI-GVHD.
• All patients receiving TPN and MEN showed improvement in GI-GVHD.
• Recovery to a normal diet ranged from 10 to 30 days, with no significant change in body weight.

Conclusions:

• Stepwise diet management, incorporating TPN and MEN, is an effective strategy for treating severe acute GI-GVHD in pediatric SCT recipients.
• This nutritional intervention facilitates rapid improvement of GI-GVHD symptoms and supports recovery without adverse effects on body weight.
