We studied the prevalence of latex-specific IgE among the children in
our myelomeningocele clinic and several groups of controls using skin
tests, a commercially available ELISA and an in-house RAST, Thirty-nin
e of 83 (47%) children with myelomeningocele had antibodies directed a
gainst latex as did 6 of 40 (15.7%) chronically ill controls, 4 of 105
(3.8%) medical controls and 2 of 75 (2.7%) well controls. Within each
study group the likelihood of a positive skin test increased with the
number of operations the subject had undergone. Children with myelome
ningocele were much more likely to have antibodies to latex than were
chronically ill controls with similar surgical histories. A retrospect
ive chart review of 18 years and a total of 646 operations disclosed o
nly one episode of intraoperative anaphylaxis which appeared to be rel
ated to latex within our study group.
