[Screening and follow-up treatment of 160 046 neonates with congenital adrenal hyperplasia in Ningxia, China].

ABSTRACT

OBJECTIVE: To investigate the incidence of congenital adrenal hyperplasia (CAH) and treatment outcomes in neonates in Ningxia, China. METHODS: The clinical data of CAH screening for 160 046 neonates who were born in midwifery institutions in Ningxia from July 2014 to March 2016 were analyzed. RESULTS: Among the 160 046 neonates who underwent CAH screening, 70 (0.044%) obtained a positive result and 11 were diagnosed with CAH; the incidence rate of CAH was 1/14 550 (0.069‰). Among the 11 neonates diagnosed with CAH, 9 had the salt wasting type (2 died) and 2 had simple virilization. The 9 neonates were given glucocorticoids immediately once diagnosed and all of them achieved good growth and development. CONCLUSIONS: The incidence of neonatal CAH in Ningxia is 1/14 550. It is very necessary to carry out CAH screening in Ningxia, and active treatment can improve the prognosis of neonates with CAH.
