Clinical analysis and identification of pediatric patients with colonic ulceration.

BACKGROUND

A wide variety of diseases mimic inflammatory bowel disease (IBD). This study aimed to reduce the misdiagnosis among children with colonic ulcers.

METHODS

Eighty-six pediatric patients with colonic ulcers detected by colonoscopy were enrolled in the retrospective study. Children were divided into different groups according to the final diagnosis. The clinical characteristics, laboratory examinations, endoscopic findings, and histopathological results were compared.

RESULTS

IBD (n = 37) was just responsible for 43% of patients with colonic ulceration. Other diagnosis included autoimmune diseases (n = 9), infectious enteritis (n = 13), gastrointestinal allergy (n = 8), and other diseases (n = 19). Comparing IBD and non-IBD groups, children with IBD had a higher frequency of symptoms like weight loss/failure to thrive (P < 0.001), perianal lesions (P = 0.001), and oral ulcers (P = 0.022), and higher expression levels of platelet (P = 0.006), neutrophil-to-lymphocyte ratio (NLR) (P = 0.001), erythrocyte sedimentation rate (P < 0.001), C-reactive protein (P < 0.001), Immunoglobulin G (P = 0.012), Interleukin-1β (P = 0.003), Interleukin-6 (P = 0.024) and TNF-α (P = 0.026), and a wider ulcer distribution in the lower gastrointestinal tract (LGIT) (P < 0.001). Expression levels of hemoglobin (P < 0.001) and albumin (P = 0.001) were lower in IBD patients. Multivariate analysis showed hemoglobin, NLR, Score of ulceration in LGIT, and pseudopolyps contributing to the diagnosis of pediatric IBD with colonic ulcers.

CONCLUSIONS

We displayed potential indicators to help diagnose pediatric IBD differentiating from other disorders with colonic ulcers more prudently.
