BACKGROUND: The combination of thiopurines and partial enteral nutrition (TP/PEN) is a common maintenance therapy for mild-to-moderate Crohn's disease (CD) in pediatric patients. However, no studies have investigated the efficacy of TP/PEN. This study aimed to evaluate the non-relapse and complete mucosal healing rates in pediatric CD patients following treatment with or without TP, in addition to PEN.
METHODS: This retrospective observational study included 39 pediatric patients diagnosed with mild-to-moderate CD. Based on the proposed treatment, the patients were divided into the TP/PEN and PEN-only groups. The primary outcome was the relapse-free rate between the two groups. Relapse was defined as a pediatric Crohn's disease activity index (PCDAI) >12.5, Simple Endoscopic Score-CD (SES-CD) score >7, Lewis score > 135, and/or abnormal C-reactive protein levels (CRP > 0.15 mg/dL). The secondary outcome was complete mucosal healing (SES-CD score 0) at 12-24 months.
RESULTS: Although the difference in non-relapse rate between the two groups was not statistically significant, complete mucosal healing rates were significantly higher in the TP/PEN group than in the PEN-only group. Complete mucosal healing at 12-24 months was achieved in 7/21 (33.3%) and 1/18 (5.5%) patients in the TP/PEN and PEN-only groups, respectively (p < 0.05).
CONCLUSION: Nowadays, more treatment options are available, and TP/PEN remains a viable option for the treatment of mild-to-moderate CD in pediatric patients.
