Abstract:
Objective:To evaluate the quality of tandem mass spectrometry (MSMS) screening for neonatal inherited metabolic diseases in Zhejiang Province from 2009 to 2021.
Methods:The data pertaining to MSMS screening for neonatal inherited metabolic diseases in Zhejiang Province from 2009 to 2021 were collected from the database created by Zhejiang Provincial Center for Neonatal Disease Screening. The percentage of MSMS screening, percentage of recall of suspected screening-positive infants and incidence of neonatal inherited metabolic diseases were analyzed retrospectively to evaluate the quality of MSMS screening for inherited metabolic diseases.
Results:A total of 4 706 916 newborns were screened among 8 297 039 live births by MSMS in Zhejiang Province from 2009 to 2021, and the percentage of MSMS screening increased from 5.48% to 97.54%, with a mean percentage of 56.73%. Of 46 838 suspected screening-positive infants, 45 527 infants were recalled, and the percentage of recall increased from 94.57% to 98.62%, with a mean percentage of 97.20%. A total of 1 038 infants were definitively diagnosed with inherited metabolic diseases in Zhejiang Province from 2009 to 2021, with an overall incidence rate of 1/4 535, and the incidence rates of amino acid metabolic disorder, fatty acid oxidation metabolic disorder and organic acid metabolic disorder were 1/11 767, 1/13 763 and 1\15 902, respectively. Of the 11 cities in Zhejiang Province, the highest percentage of tandem mass spectrometry screening for inherited metabolic diseases was found in Hangzhou City (83.01%), and the highest percentage of recall of suspected screening-positive infants was se en in Zhoushan City (99.08%).
Conclusions:A high percentage of MSMS screening for neonatal inherited metabolic diseases was observed in Zhejiang Province from 2009 to 2021; however, there was a region-specific percentage of screening, and the recall of suspected screening-positive infants remains to be improved.
