[Combined heart and kidney transplantation in Fabry's disease: Long-term outcomes in two patients]. / Transplantation combinée cœur­rein au cours de la maladie de Fabry : suivi à long terme de deux patients.

INTRODUCTION: Fabry disease is a lysosomal storage disorder linked to an alpha-galactosidase A deficiency that can lead to heart and kidney failure. There is little data about the prognosis of patients who undergo a combined heart and kidney transplantation. CASE REPORTS: Two brothers who were diagnosed with Fabry disease after the age of 30 years underwent a combined heart and kidney transplantation at respectively 49 and 42 years of age because of a severe hypertrophic cardiomyopathy with end stage renal failure. They are alive respectively 4 and 9 years after the transplantation. No recurrence of the disease in the transplanted organs has been found. CONCLUSION: Combined heart and kidney transplantation in Fabry disease is an efficient therapy for the cardiomyopathy and kidney failure. Its prognosis can be good when the patients are carefully selected. However, an early diagnosis is critical in order to avoid a procedure associated with a high perioperative mortality.

[Sirolimus-induced lymphedema in a kidney-transplant recipient: Partial recovery after changeover to tacrolimus]. / Lymphœdème induit par le sirolimus chez une greffée rénale : amélioration après remplacement par le tacrolimus.

BACKGROUND: Lymphedema induced by mTOR inhibitors is a side-effect rarely reported to date. PATIENTS AND METHODS: Long-lasting bilateral lower-limb lymphedema with left predominance developed in a 71-year-old stable renal transplant recipient after 40 months of sirolimus treatment. Although no change in lymphedema was observed after 21 months despite dosage reduced, it improved markedly after changeover to tacrolimus. DISCUSSION: Regardless of the individual drug, mTOR inhibitors can cause lymphedema. This effect may be countered through substitution with tacrolimus. CONCLUSION: Physicians should be aware of lymphedema as a side-effect of mTOR inhibitors. It can be improved by substitution with tacrolimus. However, early withdrawal of mTOR inhibitors is recommended before irreversible lymphedema occurs.
