Neonatal allergy
Joint Event on 13th International Conference on Pediatric Gastroenterology Hepatology & Nutrition & 3rd International Conference on Digestive and Metabolic Diseases
An allergy is an immune malfunction whereby a person's body is hypersensitized to react immunologically to typically
non-immunogenic substances. Allergies affect people from the early stages of their life and continue until their late adult
ages. The allergic march refers to the natural history of allergic or atopic manifestations characterized by a typical sequence
of clinical symptoms and conditions appearing during childhood and persisting for several years. The neonate is born with
a distinct immune system that is biased against the production of T-helper cell 1 (Th1) cytokines; which may guard against
rejection of the foreign fetus by the mothers immune system. There are many risk factors that increase the incidence of
neonatal allergies. Neonatal allergies could present by different non-specific symptoms and signs. Food proteins demonstrated
to cross the placenta and can be detected in amniotic fluid. Exposure to small quantities of food antigens from mothers diet
thought to tolerize the fetus, by means of IgG1 and IgG3, within a protected environment. Neonates may develop allergy to
cows milk proteins present in mothers milk or in hydrolyzed cows milk infant formulas which can be assessed by intestinal
permeability measurements. The allergy to cow milk protein may progress from dermatitis or hives to vomiting & wheeze to
Asthma and Anaphylaxis. Neonatal latex allergy could appear in neonates in NICU undergoing multiple surgical procedures
esp. myelomeningocoele. Various reactions to latex may persist chronically or precipitously develop into hypotension and
anaphylaxis. Prevention of natal allergy can be done through following different steps.
