AbstractFainting syncopal events are caused by a transient functional neuronal paralysis. Reflex syncope happens for brainstem involving mediated by peripherical afferents. Sometimes gastroesophageal reflux (GER) has been implicated in the development of obstructive apnea. Gastroesophageal reflux, despite the absence of a clinical history of vomiting and regurgitation, is observed in a significant proportion of infants presenting with ALTE (Apparent Life Threatening Event): an episode characterized by some combination of apnea, color change, marked change in muscle tone, choking or gagging. Though a cause-and-effect relationship between GER and the development of ALTE remains to be established a possible direct relationship between oesophageal acidification and the onset of alterations in cardiopulmonary function and impairment of consciousness can be hypothesized. We refer the case of two female infants that developed recurrent ALTE(s) characterized by paleness, change in muscle tone and loss of consciousness. The infants resulted affected respectively by a mild and severe gastroesophageal reflux (score: 40, > 50); in one case an episode of GER was recorded by the intraoesophageal pH-monitoring during a syncopal episode. The treatment with antiacid drugs was effectual and the infants did not present ALTE(s). The cases presented are in favour of a routine search of gastroesophageal reflux in infants presenting with one or recurrent ALTE(s). The identification of these infants will permitt to develop a correct strategy of treatment.
