BU-COIFIU FANEGO, Raisa et al. Neuron- specific Enolase in two newborns presenting with moderate depression at birth. Rev Cubana Pediatr [online]. 2009, vol.81, n.1, pp. 0-0. ISSN 1561-3119.
INTRODUCTION: Neuron-specific Enolase of is an isoenzyme present in blood stream after a neuronal damage episode. In processes of neonatal hypoxia, these enzymatic values in serum may be altered. The aim of present paper was to study Enolase specific of neuron in the serum of two newborns with low Apgar score and to determine if, during a one year follow-up, such patients presented disorders of psychomotor development. METHODS: We took serum samples at birth and at 72 hours. Levels of Enolase specific of neuron by immunoenzymatic method type ELISA were determined. Each sample was assessed by polymerase chain reaction (PCR) to cytomegalovirus in Wuersburg Institute of Immunology (Germany). Also, we quantified antibodies to IgM and IgG cytomegalovirus in Neurochemistry Institute of Georg August of Goettingen University (Germany). Interesting clinical data of each newborn were collected and after a year, all these patients were cited for a physical examination to evaluate tits neurodevelopment. RESULTS: Enolase figures were increased both at birth and at 72 hours, with IgG anticytomegalovirus antibodies from mother through placenta. At birth there was not presence of this virus. At physical and neurological examination performed at 1 year it was possible to confirm that children evolved adequately until now. CONCLUSIONS: Study must to be prolonged until 3 years of life, and to increase number of study patients, emphasizing on those with an Apgar score lower than 5 at 5 minutes post-birth.
