RESUMEN
El síndrome de intestino corto constituye una entidad con alteración en la superficie de absorción y en la funcionalidad del sistema gastrointestinal. En estos pacientes se ha descrito mayor predisposición de alergias alimentarias a la proteína de la leche de vaca y al huevo. Se describen los casos de 2 lactantes menores con síndrome de intestino corto y reacciones alérgicas a fórmulas de aminoácidos libres. En el primer caso la paciente presentó una respuesta no mediada por inmunoglobulina E (IgE) manifestada clínicamente con una colitis eosinofílica, que mejoró con uso de esteroides sistémicos, cambio a otra fórmula elemental. En el segundo caso se presenta una paciente con intolerancia inicial a la leche materna y fórmula extensamente hidrolizada. Con primera fórmula de aminoácidos libres presenta sangrado gastrointestinal y manifestaciones cutáneas, por lo que se hace cambio a otra fórmula de aminoácidos libres con tolerancia transitoria. Subsecuentemente, en el contexto de un cuadro viral no especificado con compromiso respiratorio y gastrointestinal, presenta reacción anafiláctica a la fórmula de aminoácidos libres que venía tolerando previamente, por lo que se hace necesario cambio a dieta modular con tolerancia adecuada. No se encontraron reportes previos en la literatura de reacciones alérgicas a fórmulas elementales a base de aminoácidos, por lo cual se reportan los casos descritos. Aún no hay consenso en cuanto a la fórmula ideal para iniciar la alimentación en los pacientes con intestino corto para evitar sensibilización alergénica.
ABSTRACT
Short bowel syndrome (SBS) is characterized by alterations in the absorption surface and in the functionality of the gastrointestinal system. Patients with SBS are more prone to allergies the protein in cow's milk and eggs. We report two cases of infants with SBS and allergic reactions to amino acid based formulas. In the first case, the patient's response was not IgE-mediated. It manifested clinically with eosinophilic colitis that improved with the use of systemic steroids and a change to another elemental formula. In the second case, the patient initially presented intolerance to breast milk and extensively hydrolyzed formula. After feeding with the first free amino acid formula, the patient developed gastrointestinal bleeding and skin manifestations. Another free amino acid formula was substituted. The patient had transient tolerance to the new formula. Later, in the context of an unspecified viral infection with respiratory and gastrointestinal involvement, the patient presented an anaphylactic reaction to the formula which had previously been tolerated. This necessitated a change to a modular diet which was adequately tolerated. We have presented this case report because no previous reports were found in the literature about allergic reactions to basic amino acid-based formulas. There is still no consensus on the ideal formula for preventing allergic sensitization in patients with SBS.
