| Popis: | Creatine kinase isoenzyme BB was determined in cerebrospinal fluid (CSF) in 79 preterm neonates using an original enzyme-linked immunosorbent assay. The criterion for inclusion was an Apgar score of 7 or less at 5 min of life. Neurological examination was performed on day 2 and day 5 of life. CSF was obtained on the same days. Lumbar puncture was performed on 41 of these babies on day 2 and in 39 on day 5 of life (one baby underwent lumbar puncture twice). All babies had clinical features of hypoxic-ischemic encephalopathy (HIF) which was classified according to Sarnat and Sarnat. The control group consisted of 90 asphyxiated term babies and 30 adults without CNS pathology. The concentration of CK-BB in cerebrospinal fluid (meanSD) was significantly higher (p < 0.0005) in preterm (168.0 2) than in term babies (29.0 3.1) and healthy adults (5.3 1.2). Our results demonstrate the possibility of using the classification system of Sarnat and Sarnat for assessment of the severity of brain damage not only in term, but also in preterm babies. Neonates with HIE stages II and III showed markedly higher CK-BB values than those with HIE I on day 2 (p < 0.025) and day 5 (p < 0.05) of life. CK-BB values were markedly higher in preterm babies with none of some primitive responses (head turning, Babkin's reflex, palmar grasp). The mean concentration of CK-BB was higher in neonates with retarded psychomotor development compared with those with normal development (p < 0.05) on day 3, and after 6 and 9 months. At 12 months of age no significant difference in median CK-BB concentration was detected between neonates with normal and developmental disturbances.Asphyxia, cerebrospinal fluid, creatine kinase BB isoenzyme, hypoxic-ischemic encephalopathy, neonates |
