Successful pregnancies and fatherhood in familial amyloidotic polyneuropathy (FAP Val30Met) patients with liver transplantation

For familial amyloidotic polyneuropathy (FAP) patients, several problems regarding reproduction are present. For males, erectile dysfunction and retrograde ejaculation are well known complications of the disease In addition, the risk of transferring a fatal disease to their offspring is a matter of concern for the patients. For transplanted fertile patients, the risk of side effects of immunosupression therapy causing congenital malformations must be addressed, and for female patients the additional risk of complications during pregnancy and delivery is a case of concern. After delivery, the problem of breast-feeding arises. In the Swedish population of transplanted patients, five successful pregnancies, of which male FAP recipients fathered three, are reported. All patients were on stable immunosuppressive therapy with cyclosporine or tacrolimus and prednisolone. From our experience, successful fatherhood and pregnancy is possible for liver transplanted FAP patients, as it has been reported for patients transplanted for other medical reasons.
