Purpose:
To investigate the relationship of IgE-mediated allergy and complicated appendicitis (CA) and overall prognosis.
Methods:
We retrospectively analyzed a consecutive series of patients with acute appendicitis (AA) who received appendectomy at Beijing Children's Hospital between July 1, 2018 and June 30, 2020. Patients were classified into two groups, with or without IgE-mediated allergies. Logistic regression adjusting for age, duration of symptoms, WBC count, neutrophil count, C-reactive protein (CRP), Appendicolith and presence of allergy was used to evaluate the association between CA and IgE-mediated allergy.
Results:
In total, 1156 patients were included. 162 (14.0%) of the patients had IgE-mediated allergy while 994 (86.0%) did not. Children with allergies had a decreased chance of developing CA after adjustment for age, duration of symptoms, WBC count, Neutrophil count, CRP, and appendicolith present rate (adjusted OR = 0.582, 0.364-0.929, P = 0.023). There were no significant differences in operative time, length of hospital stay (LOS), readmission, or adhesive intestinal obstruction rate between allergy and non-allergy patients.
Conclusions:
IgE-mediated allergy is related to a reduction risk of CA in the pediatric population and may not affect the prognosis of patients received appendectomy.

Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
