Marked transient alkaline phosphatemia following pediatric liver transplantation.
An isolated marked transient rise in serum alkaline phosphatase levels in otherwise healthy children is a well-documented occurrence. However, in children undergoing liver transplantation, elevated alkaline phosphatase values raise the possibility of biliary obstruction, rejection, or both. During a 6-year period, 6 of 278 children undergoing liver transplantation exhibited a similar phenomenon as an isolated abnormality. None had rejection, biliary obstruction, or other allograft dysfunction during a long follow-up. Eventually and without intervention, the alkaline phosphatase levels returned to normal. These instructive cases suggest that caution be used in advocating invasive procedures if elevated alkaline phosphatase levels are an isolated abnormality, and close observation with noninvasive testing is recommended.
