Gastroesophageal Reflux Disease and Sudden Infant Death: Mechanisms behind an Under-Recognized Association

We present 4 cases of sudden infant death in which we believe that gastroesophageal reflux (GOR) was a contributory, if not a causative, factor. Two of our patients had documented GOR reflux disease during life, and all 4 cases showed histologic evidence of GOR. No other cause of death was identified in any of the patients. Gastroesophageal reflux can cause sudden death in a vulnerable infant during a critical period of development through failure of “autoresuscitation” mechanisms.
