Background: Children with spina bifida (SB) are exposed to latex soon after birth during bladder catheterization, rectal disimpaction, and multiple surgical procedures. IgE?mediated latex?allergic reactions have been reported recently in these children. Our study was designed to assess the prevalence of allergic reactions to latex products in a group of Saudi Arabian children with SB in a tertiary care hospital. Methods: Fifty?nine patients, aged 1-20 years, with SB were evaluated by a questionnaire on type of latex reactions; family and personal history of other allergic disorders, such as asthma, rhinitis, and urticaria; type and number of surgical procedures; and frequency of bladder catheterization and manipulation with latex materials. Confirmation of latex sensitivity was measured by skin prick test (SPT), CAP test, and latex skin challenge. Results: Allergy to latex was detected in 25% of the study group. There was a significant variation in allergic reaction by sex (males 42%, females 12%) (P<0.01), use of catheters (yes 38%, no 13%) (P<0.05), and urologic surgery (yes 60%, no 18%) (P<0.01). The number of surgical procedures, age of patient, and V-P shunt were not significantly related to allergic reactions. Conclusions: Our findings support previous studies indicating a high prevalence of latex allergy among SB patients. The CAP test was a more sensitive measure of latex allergy in SB patients than SPT or latex challenge. There was significant correlation with urologic procedures and the use of urethral catheters.
