title: The long-term impact of liver transplantation on kidney function in familial amyloidotic polyneuropathy patients.
abstract: The aim of the study is to evaluate the long-term kidney function after liver transplantation (LTx) in familial amyloidotic polyneuropathy (FAP) Portuguese type patients and compare the findings with patients transplanted for chronic liver disease of other origin. We analysed the medical records of 32 FAP patients who underwent transplantation between 1990 and 1999 with a follow-up of more than 1 year after LTx. The control group consisted of 61 patients who had undergone LTx for chronic liver disease. Kidney function was measured by the glomerular filtration rate (GFR), serum creatinine and urea. There were no differences between the groups in creatinine and urea levels during the follow-up. However, during the first year after transplantation, the increase in creatinine and urea was significantly higher in the control group (P < 0.01). The decline in GFR after transplantation was also more pronounced in the controls (P < 0.01). Initially after LTx, kidney function deteriorated in both FAP and control patients, but the deterioration was more pronounced in the controls. The decline of the FAP patients' kidney function after LTx was not more pronounced than that observed in control patients, although many FAP patients' kidney function was impaired before the procedure, suggesting that LTx may halt the progression of kidney damage caused by amyloid deposition.
