[Platelet factor 4 levels in full-term newborns undergoing phototherapy].
PF4 levels and platelets counts were studied in a group of 15 term newborn infants before treatment and after 24-48-72 and 96 hours of phototherapy and in a control group of 10 babies. Unlike data found by other AA. in vitro and in preterm infants, our values show only minimal, not statistically significant, differences in PF4 levels and platelets counts between the two groups. The AA. believe that in term infants, with adequate weight for gestational age, proper phototherapy treatment does not cause any change in platelet function, owing to the thicker and more mature skin and to the better bone marrow compensation typical of term versus preterm infants.
