Lithium and the living kidney donor: Science or stigma?

Nearly 10 000 people are removed from the kidney transplant waiting list each year either due to becoming too ill for transplant or due to death. Live donor kidney transplant (LDKT) provides superior outcomes and survival benefit relative to deceased donor transplant, but the number of LDKT has decreased over the past few years. Therefore, it is of paramount importance that transplant centers employ evaluation processes that safely maximize LDKT. Decisions about donor candidacy should be based on the best available data, rather than on processes prone to bias. Here, we examine the common practice of declining potential donors based solely on treatment with lithium. We conclude that the risk of endstage renal disease related to lithium treatment is comparable to other generally accepted risks in LDKT. We present this viewpoint to specifically challenge the carte blanche exclusion of individuals taking lithium and highlight the importance of using the best available data relevant to any risk factor, rather than relying on biases, when evaluating potential living kidney donors.

Nearly 10,000 people are removed from the kidney transplant waiting list each year due to illness or death. Live donor kidney transplant (LDKT) provides better outcomes and survival benefit, but the number of LDKT has decreased in recent years. It is important to use the best available data and avoid biases when evaluating potential living kidney donors.
