Is protocol liver biopsy the only examination that can detect mid-term graft fibrosis after pediatric liver transplantation?
PLB at two years after LT is an unnecessary examination, because the serum ALT level reflects portal inflammation. In addition, immunosuppressive therapy should be modulated to maintain the ALT concentration at a level less than 20 IU/L. PLB at five years is an excellent examination for the detection of early reversible graft fibrosis because no serum markers reflect this finding.
The BBB was impaired around watershed areas by 25°C HCA for 1 hour according to both macroscopic and microscopic data. An increase in permeability of the BBB may be both a sign and a mechanism of brain damage.
