| Popis: | Domino liver transplantation is one possibility to overcome the discrepancy between the small number of liver donors and the long waiting lists. Homozygous familial hypercholesterolemia (FHC) is a genetic disorder of lipoprotein metabolism defined by the absence or small number of functional low-density lipoprotein receptors (LDL-Rs) and the ensuing high levels of serum cholesterol. We report a case of a patient with FHC whose liver was used for domino transplantation in a patient with cirrhosis and hepatocellular carcinoma.The patient diagnosed with FHC received the large part of a split liver. The liver of the patient with FHC was then transplanted into the patient with cirrhosis and hepatocellular carcinoma. Quantification of extrahepatic LDL-R was performed by flow cytometry on monocytes, and the gene expression of LDL-R was assayed by reverse transcriptase-polymerase chain reaction on monocyte-derived macrophages and cultured fibroblasts isolated from the patients.One year after surgery, the donor's serum cholesterol (without treatment) was normal, and the recipient's serum cholesterol (with simvastatin treatment) was slightly increased. Quantification of peripheral LDL-R on monocytes isolated from the patients revealed values of 6.7% in the patient with FHC and 71% in the patient with cirrhosis and hepatocellular carcinoma. The reverse transcriptase-polymerase chain reaction assay revealed the presence of gene expression for LDL-R.Domino transplantation can be efficiently used in a patient with marginal indications for transplantation using a liver from a patient with FHC. The slightly elevated serum cholesterol level in the recipient may be explained by the normal function of extrahepatic LDL-R. |
