Correlation Analysis of TSB Level and Globus Pallidus-Related Metabolite Indexes of Proton Magnetic Resonance Spectroscopy in the Newborn with Neonatal Jaundice. (4th July 2022) - Liu, Chaoyan
Abstract : Objective . To investigate the correlation between serum total serum bilirubin (TSB) levels and globus pallidus-related metabolic indexes of proton magnetic resonance spectroscopy (1H-MRS) in the newborn with neonatal jaundice. Methods . 50 children with neonatal jaundice admitted to our hospital from January 2019 to January 2021 were recruited and assigned to a mild condition group (TSB < 221 μ mol/L, n = 16), a moderate condition group (221 μ mol/L ≤ TSB < 3 42 μ mol/L, n = 18), and a severe condition group (342 μ mol/L ≤ TSB < 428 μ mol/L, n = 16) based on peak TSB. The differences in globus pallidus-related metabolic indexes of 1H-MRS between the groups were compared and their correlation with TSB levels was analyzed. Results . The three groups had comparable N-acetylaspartic acid (NAA)/creatine (Cr), choline (Cho)/Cr, lactic acid (Lac)/Cr, and ml/Cr levels (P > 0.05 ), while there were statistical differences in glutamine (Glx)/Cr levels (P < 0.05 ). The severe condition group showed the highest levels of neuron-specific enolase (NSE), creatine kinase-MB (CK-MB), and troponin (cTnl), followed by the moderate group, and then the mild group (P < 0.05 ). The TSB level is positively correlated with the 1H-MRS metabolic index Glx/Cr. Conclusions . The serum TSB level is correlated with the 1H-MRS metabolic index Glx/Cr in the newborn with neonatal jaundice, and the levels of TSB and Glx/Cr provide a reference for the diagnosis of bilirubin encephalopathy.
