Risk factors for latex sensitization in children with spina bifida.
BACKGROUND: Children with spina bifida represent the major risk group for latex sensitization.Purpose: To determine the prevalence of latex sensitization in these children and to identify risk factors. MATERIAL AND METHODS: We studied 57 patients with spina bifida. The mean age was 5.6 years and the male/female ratio was 0.8/1. In all patients a questionnaire, skin prick test (SPT) with latex (UCB-Stallergènes, Lofarma and ALK-Abelló), common aeroallergens and fruits (UCB-Stallergènes) and serum determination of total IgE (AlaSTAT) were performed. RESULTS: The prevalence of latex sensitization was 30 %; only two sensitized children (12 %) had symptoms after exposure. Risk factors for latex sensitization were age >/= 5 years (p = 0.008; OR = 6.0; 95 % CI = 1.7-22.1), having at least four previous surgical interventions (p < 0.0001; OR = 18.5; 95 % CI = 3.6-94.8), having undergone surgery in the first 3 months of life (p = 0.008; OR = 5.4; 95 % CI = 0.7-29.2) and total serum IgE >/= 44 IU/ml (p = 0.03; OR = 3.8; 95 %CI = 1.1-13.1). Multiple logistic regression analysis showed that only a history of four or more surgical interventions (p < 0.0001; OR = 26.3; 95 %CI = 2.9-234.2) and total serum IgE >/= 44 IU/ml (p = 0.02; OR = 8.6; 95 % CI = 1.4-53.4) were independently associated with latex sensitization. Sex, family and personal allergic history, hydrocephalus with ventriculoperitoneal shunt, cystourethrograms, intermittent bladder catheterization and atopy were not related to latex sensitization. CONCLUSIONS: In children with spina bifida, significant and independent risk factors identified for latex sensitization were multiple interventions and higher levels of total serum IgE. A prospective study will clarify the clinical evolution of assymptomatic children sensitized to latex.[1]References
