title: Serum creatine kinase BB as predictor of periventricular haemorrhage in preterm infants.
abstract: Serum creatine kinase BB (CK-BB) determinations were performed daily in 49 newborn infants of less than 34 weeks gestation to evaluate its usefulness in predicting the occurrence of periventricular-intraventricular haemorrhage (PIVH). Using ultrasound PIVH was detected in 20 infants (41%); five grade I, seven grade II, two grade III, six grade IV (grading according to Papile et al.). Infants who developed severe PIVH (grade IV) during the study period had significantly higher serum CK-BB activities immediately after birth when compared with infants who developed less severe haemorrhages (grades I, II and II) or no PIVH. We postulate that these high serum enzyme activities are caused by perinatal brain cell damage which is an important antecedent of severe PIVH. Therefore, serum CK-BB activities at birth can be used as predictor of severe PIVH.
