Liver transplantation in oxalosis prior to advanced chronic kidney disease

While curative of the disease, combined kidney and liver transplantation (K/LTx) for primary hyperoxaluria type 1 (PH1) continues to carry with it a risk for patient death of 15-25%, which over time may not differ from that of kidney transplantation alone (KTx). In this editorial, survival data are reviewed as well as the limited data available for kidney graft function, which may favor K/LTx in the short term but is more uncertain in the longer term. The window of opportunity that favors preemptive K/LTx is relatively narrow and is likely even narrower for preemptive isolated LTx. Capability and experience in the medical management of such patients, and the opportunities available, as well as likely patient compliance, so far without supporting data, may be the most important determination of the best strategy for management.
