Pseudoreflux syndrome-increased periodic breathing during the neonatal period presenting as feeding-related difficulties.
Sixteen infants who presented with symptoms suggestive of gastroesophageal reflux (GER)-associated apnea were evaluated at the Breathing Disorder Center of the Children's Hospital of Philadelphia. These neonates had a history of occasional emesis and an apparent life-threatening event (ALTE) that occurred while awake which was similar to the presentation of a group of infants previously described. Evaluation of the present group of infants however, revealed increased periodic breathing (12.1 +/- 1.8 SEM% of total sleep time) as opposed to the obstructive apnea that was typically seen with GER. Pathologic gastroesophageal reflux could not be diagnosed in relationship to apneic events. Infants who present during the first month of life with symptoms suggestive of GER-associated apnea should have careful evaluation of reflux and respiratory patterns to confirm the correct diagnosis. Because of the similarities of these infants to the GER group, we have called their disorder pseudoreflux.
