Patients with 21-hydroxyase deficiency (21-OHD) usually do not present clinical symptoms other than female ambiguous genitalia and skin pigmentation at birth. However, we have found a case of neonatal transient tachypnea with spontaneous pneumomediastinum in a neonate with 21-OHD at birth. The purpose of this study was to investigate the occurrence of neonatal respiratory disorders in 21-OHD patients. From April 1989 to March 2009, 478,337 Japanese newborns were screened for congenital adrenal hyperplasia in Niigata prefecture. Among these newborns, 26 patients were diagnosed as having 21-OHD. We investigated the presence of neonatal respiratory disorders based on the retrospective medical records of 24 full-term patients with 21-OHD. Three of the 24 patients (12.5%) had neonatal acute respiratory disorders. Neonatal transient tachypnea developed in all patients with only oxygenation for two or three days after birth. Chest X-rays showed spontaneous pneumothorax or pneumomediastinum in two patients. In conclusion, 21-OHD patients may present with acute respiratory disorders, especially transient tachypnea with spontaneous pneumothorax, at birth. In cases of delivering mothers having other children with 21-OHD, newborns require attention regarding neonatal respiratory disorders if a prenatal diagnosis has not been performed.
