Clinical study on serum changes of homocysteine, folate and vitamin B12 in different clinical indexes of neonatal hypoxic ischemic encephalopathy / 天津医药

ABSTRACT

Objective To determine the correlation between high serum levels of homocysteine (Hcy), low folate and vitamin B12 levels and the clinical index of neonatal hypoxic ischemic encephalopathy (HIE), providing the reference for the diagnosis and treatment of neonatal patients with HIE. Methods Totally 94 cases of neonatal patients with HIE (32 mild, 40 moderate, and 22 severe) treated by Tianjin children’s hospital from April 2010 to April 2011 were enrolled. The control group was 20 cases of neonatal patients with neonatal swallowing syndrome at the same period. The serum levels of Hcy, folate and vitamin B12 were compared between four groups. Results There were significant differences in serum levels of Hcy, folate and vitamin B12 between four groups (P<0.05). Compared with the control group, there was higher level of Hcy and lower levels of folate and vitamin B12 in HIE groups. The Hcy levels increased with the deterioration of HIE in three HIE groups. The serum level of vitamin B12 was significantly lower in severe group than that in moderate group (P<0.05). Conclusion The serum Hcy level has certain reference value in tassessment of the severity of HIE. The supplementation of folate and vitamin B12 may play an active role in the process of the treatment in neonatal patients with HIE.
