Resumo

JUSTIFICATIVA E OBJETIVOS: O número de pacientes alérgicos ao látex vem aumentando significativamente. É essencial reconhecê-los para preve nir e aplicar o tratamento adequado. O objetivo do estudo foi avaliar a prevalência de alergia ao látex em pacientes com mielomeningocele. MATERIAIS E MÉTODOS: Foram avaliados, retrospectivamente, os prontuários médicos de pacientes com diagnóstico de mielomeningocele no período de janeiro de 2002 a dezembro de 2007. Os pacientes foram agrupados em alérgicos e não alérgicos. A comparação dos grupos em relação ao gênero foi feita pelo teste do Qui-quadrado, pelo teste t de Student em relação à idade, e o teste de Mann-Whitney para comparação entre os grupos em relação as manifestações clínicas de alergia, número de procedimentos sob anestesia, de internações hospitalares e de cateterizações vesicais. RESULTADOS: O número médio de procedimentos sob anestesia foi de 7 no grupo com alergia e 4 no grupo sem alergia, sendo esta diferença estatisticamente significante (p = 0,028). O número médio de internações hospitalares foi de 4,5 no grupo com alergia e 3,4 no grupo sem alergia e a média de cateterização vesical foi 24,5 nos alérgicos e 21,7 nos não alérgicos. CONCLUSÕES: Os pacientes portadores de mielomeningocele submetidos a múltiplos procedimentos sob anestesia apresentam alto risco de desenvolvimento de sinais clínicos de alergia ao látex. Há necessidade de que pacientes com diagnóstico de mielomeningocele sejam submetidos exclusivamente a procedimentos latex-free, evitando o alto risco de sensibilização e suas complicações. Testes específicos para avaliação da sensibilização, marcadores genéticos e relação látex-fruta poderão contribuir para melhor entendimento dos fatores de risco relacionados à alergia ao látex e formas de prevenção

Abstract

BACKGROUND AND OBJECTIVES: The number of patients allergic to latex has increased significantly. It is crucial to recognize the cases in order to prevent and apply adequate treatment. The objective of this study was to evaluate the prevalence of allergy to latex in meningomyelocele patients. MATERIALS AND METHODS: A retrospective evaluation of medical records of patients with meningomyelocele diagnosis from January 2002 to December 2007 was conducted. Patients were grouped into allergics and non-allergics. The comparison of groups for gender was made by the Chi-Squared test, the Student's t test was used to compare age, and Mann-Whitney test was used to compare groups for clinical manifestations of allergy, number of procedures under anesthesia, hospital admissions and vesical catheterizations. RESULTS: The mean number of procedures under anesthesia was 7 in the group with allergy and 4 in the group without allergy; this difference was statistically significant (p = 0.028). The mean number of hospital admissions was 4.5 in the group with allergy and 3.4 in group without allergy and mean vesical catheterization was 24.5 in allergic patients and 21.7 in non allergic ones. CONCLUSIONS: Meningomyelocele patients undergoing multiple procedures under anesthesia have high risk of developing clinical signals of allergy to latex. It is necessary that patients with meningomyelocele diagnosis should undergo exclusively latex-free procedures, avoiding high risk of sensitization and its complications. Specific tests to evaluate sensitization, genetic markers and latex-fruit relationship may contribute to a better understanding of risk factors related to allergy to latex and ways to prevent it
