Investigation of Allergen Sensitization in Newborn Babies Diagnosed With Necrotizing Enterocolitis. (AlisNEC)

实验性的：NEC Study Group

Neonates diagnosed with Necrotizing enterocolitis during the neonatal period who are eveluated for allergens sensitization

诊断测试：skin prick test

Skin Prick Test Procedure:

The SPT was performed when patients were free of acute health problems, and medications that could affect test results had been discontinued. A histamine solution (10 mg/mL, ALK-Abelló®, Canada) was used as a positive control, and 0.9% sodium chloride was used as a negative control. The test was performed on the volar surface of the forearm, and results were read after 20 minutes. A wheal ≥3 mm greater than the negative control, with erythema, was considered positive (Heinzerling L, et al. Clin Transl Allergy 2013;3:3).

Sensitization to aeroallergens, including house dust mites (Dermatophagoides farinae, Dermatophagoides pteronyssinus), grass pollen mix, tree pollen mix, mold mix, cat epithelium, dog epithelium, and cockroach extract (ALK-Abelló®, Canada), was assessed. Sensitization to food allergens (cow's milk, egg, wheat, nuts, fish, and soy) was also evaluated using commercial extracts (ALK-Abelló®, Canada).

The effect of necrotizing enterocolitis development in premature infants on response to allergens.

The primary objective of this study was to compare the positivity rates on skin prick tests for airway allergens or food allergens in premature infants who developed NEC and those who did not, between the ages of 12 and 24 months.
