RESUMO
PURPOSE: Neurodevelopmental disorders, such as autism spectrum disorder (ASD), have been increasingly associated with eosinophilic gastrointestinal disorders (EGID). However, the relationship between these diseases remains unclear. We performed a systematic review with meta-analysis to address this issue. METHODS: The search was performed according to the PRISMA guidelines using descriptors for ASD and EGIDs from the MEDLINE, Embase, PsycInfo, LILACS, and Web of Science databases. Observational studies with the prevalence of ASD in any EGID were included. The study protocol was registered on the PROSPERO platform under the number CRD42023455177. RESULTS: The total dataset comprised 766,082 participants. The result of the single-arm meta-analysis showed an overall prevalence of ASD in the population with EGID of 21.59% (95% CI: 10.73-38.67). There was an association between EGID and ASD (OR: 3.44; 95% CI: 1.25-2.21), also significant when restricted only to EoE (OR: 3.70; 95% CI: 2.71-5.70). DISCUSSION: Recent studies have implicated the influence of an inadequate epithelial barrier integrity in the pathogenesis of several diseases. The role of this mechanism can be extended to situations beyond allergic reactions, including other conditions with underlying immunological mechanisms. Several diseases are potentially related to the systemic effect of bacterial translocation in tissues with defective epithelial barriers. CONCLUSION: Our meta-analysis provides evidence that supports the consideration of EGID in patients with ASD and ASD in patients with EGID. Despite its limitations, the results should also be validated by future studies, preferably using multicenter prospective designs in populations with low referral bias.

Introducción. La alergia alimentaria y la fibrosis quística (FQ) son patologías complejas que pueden acontecer concomitantemente. Aunque pareciera poco frecuente, durante la práctica clínica se han observado varios casos de presentación simultánea. Dado lo anterior, nace el interés de observar el comportamiento de la alergia alimentaria en los pacientes con FQ vistos en una clínica de referencia para ambas entidades. Objetivo. Determinar la prevalencia de alergia alimentaria en la población de fibrosis quística que asiste a la consulta de gastroenterología pediátrica de la IPS Gastronutriped en Bogotá entre los años 2009 y 2013. Metodología. Se realizó un estudio retrospectivo, en pacientes de ambos géneros de 0 a 18 años de edad con diagnóstico de FQ, atendidos en la Unidad de Gastroenterología, Hepatología y Nutrición Pediátrica -IPS Gastronutriped- entre el 2009 y el 2013, con la revisión de historias clínicas para definir si habían tenido o tenían además, diagnóstico de algún tipo de alergia alimentaria. Resultados. Se documentó que 14,8% (n=4/27) de la población con FQ analizada presentó algún diagnóstico de alergia alimentaria, con variedad en el tipo de expresión clínica. Conclusión. En un paciente con FQ que persiste con síntomas gastrointestinales a pesar de un adecuado tratamiento y adherencia al mismo, es fundamental sospechar otras patologías independientes que al tiempo, comprometan el tracto gastrointestinal.
Introduction: Food allergies and cystic fibrosis (CF) are complex diseases that may occur concomitantly. Although this seems uncommon, several cases of simultaneous presentation have been observed in our clinical practice. Given this, we developed an interest in observing the behavior of food allergies in CF patients seen at a referral clinic for both entities. Objective: The objective of this study was to determine the prevalence of food allergies in cystic fibrosis patients at the outpatient pediatric gastroenterology clinic of Gastronutriped IPS in Bogotá between 2009 and 2013. Methodology: This is a retrospective study of male and female patients diagnosed with CF and treated at the Unit of Gastroenterology, Hepatology and Nutrition of Gastronutriped IPS between 2009 and 2013. Patients ages ranged from newborns to 18 years old. We reviewed their medical records to determine whether they also had been diagnosed with any type of food allergy. Results: We found that 14.8% (n = 4/27) of the CF population analyzed presented diagnoses of food allergy, although the clinical expressions of these allergies varied. Conclusion: When gastrointestinal symptoms persist in patients with CF despite adherence to proper treatment, it is essential to suspect other independent pathologies that may compromise the gastrointestinal tract.
