[Normal levels of carboxyterminal propeptide of type I procollagen in the first three months of life].
Serum levels of type I procollagen were measured on 118 samples from cord blood or from healthy infants aging from 1 to 90 days of life. Significant variations (P = 0.001) were noticed in the values of the marker in the whole period under investigation. We observed a decrease of PICP from cord blood to the end of the first day of life with a sharp rise on the 5th day lasting until the 30th day which then became stable till the end of the third month. Our results show a peculiar pattern of PICP levels during the first month of life which has to be taken into account to evaluate normal values of the marker in this period of life.
