There is marked interindividual variability in trough blood levels of tacrolimus (TRL) following standard dosing. TRL is a substrate for P-glycoprotein (P-gp), the product of the multidrug resistance-1 (MDR1)(ABCB1) gene. P-gp acts as a membrane efflux pump, which affects TRL absorption from the gut. ⋯ TRL daily doses were significantly lower among patients with the 3435 TT genotype at months 1 and 6. At 6 and 12 months after transplantation patients who were homozygous for the ABCB1 3435 CC showed significantly lower dose-adjusted trough TRL concentrations compared with subjects of 3435 TT and CT genotypes. Knowledge of ABCB1 genotype may be useful to adjust the optimal dose of TRL in transplant patients, thereby rapidly achieving target concentrations.

Case Reports
Liver transplantation of a child with child a cirrhosis and severe hepatopulmonary syndrome.
Hepatopulmonary syndrome (HPS) is a clinical state defined by a chronic hepatic disorder, intrapulmonary vascular dilatation, and altered gas exchange resulting in hypoxemia. Cirrhosis of the liver is the most common condition associated with HPS. ⋯ The findings of HPS resolved immediately after OLT. His status is within normal limits at 6 months after liver transplantation.

Early arterial or portal vein thrombosis is a complications that can lead to graft loss and patient death or need of immediate retransplantation. The aim of the study was to assess the incidence, causes, treatment, and outcome of vascular thrombosis after living related donor liver transplantation (LRdLTx). Between 1999 and 2004 71 LRdLTx were performed in children aged from 6 months to 10 years. ⋯ Any risk factors of vascular thrombosis that can be controlled should be avoided after transplantation. Routine posttransplant Doppler examination should be performed at least twice a day within 7 to 14 posttransplant days. Immediate thrombectomy should be always carried out to avoid late complications and even mortality.
