Latex allergy is an IgE-mediated immediate hypersensitivity response to natural rubber latex ( NRL ) protein with a variety of clinical signs ranging from contact urticaria , angioedema , asthma , and anaphylaxis . Anaphylaxis : Immediate hypersensitivity response to antigenic challenge , mediated by IgE and mast cells . This process may possibly be integral in developing the new immune system.The high frequency of eosinophilia suggests an allergic basis , leading some authors to suggest that ETN may be an immediate hypersensitivity reaction to a substance passed from the mother transplacentally ; however , convincing support is lacking for this theory.No responsible exotoxin , allergen , component of sebum , or infectious agent has been linked credibly to ETN.Medications administered to newborns and the mode of feeding have no effect on incidence.Other proposed theories include a transient adjustment reaction of the skin to mechanical or thermal stimulation or an acute graft-versus-host reaction induced by the maternal-fetal transfer of lymphocytes before or during delivery.Risk factors include birth in hot , wet climates , being fed on a mixed diet or milk powder substitute , and being born via vaginal delivery .
