Abstract
OBJECTIVE: To explore the reasonable and effective enteral nutrition regimen for children with abdominal Henoch-Schönlein purpura (HSP). METHODS: A retrospective analysis was performed on the medical data of children with abdominal HSP who were hospitalized from August 2013 to August 2018. According to the starting time of enteral nutrition after abdominal pain relief, the children were divided into three groups: < 24 hours (n=68), 24-48 hours (n=64), and 48-72 hours (n=60). According to the type of enteral nutrition, they were divided into another three groups:amino acid-based formula (n=53), extensively hydrolyzed lactoprotein formula (n=67), and normal diet (n=72). The recurrence rate of clinical symptoms and degree of satisfaction among family members were compared between groups. Based on the retrospective analysis, 166 children with abdominal HSP were enrolled in a prospective study. They were given extensively hydrolyzed lactoprotein formula after abdominal pain relief. According to the feeding time after abdominal pain relief, they were divided into three groups: < 24 hours (n=52), 24-48 hours (n=59), and 48-72 hours (n=55). The three groups were compared in terms of the recurrence rates of abdominal pain, rash, and hematochezia, the rate of use of parenteral nutrition and intravenous steroids, and the incidence rate of weight loss at discharge. RESULTS: The retrospective analysis showed that the children who were given extensively hydrolyzed lactoprotein formula for enteral nutrition at 24-48 hours after abdominal pain relief had a lower recurrence rate of clinical symptoms and the highest degree of satisfaction among their family members (P < 0.0167). The prospective study showed that the children who were given extensively hydrolyzed lactoprotein formula for enteral nutrition at 24-48 hours after abdominal pain relief had lower recurrence rates of rash and abdominal pain, a lower rate of use of parenteral nutrition, and a lower incidence rate of weight loss at discharge (P < 0.05). CONCLUSIONS: It is reasonable and effective to start the feeding with extensively hydrolyzed lactoprotein formula at 24-48 hours after abdominal pain relief in children with abdominal HSP.
