Introduction

This is a book about living solid organ donors as patients in their own right. It is premised on the supposition that the field of living donor organ transplantation is ethical, even if some instantiations are not, eg, pre-mortem organ procurement of an imminently dying patient. In this chapter, the objection to living solid organ donation based on the obligation to do no harm is rejected because it ignores the fact that for many living donors, the benefits outweigh the harms. It is argued that the principle of respect for persons permits some living solid organ donation provided that both the donor and the recipient are treated as patients in their own right. This chapter then provides an outline for the rest of the book in which a five-principle living donor ethics framework is developed and applied to various living donor transplant proposals.

Clinical factors associated with severe hypophosphataemia after kidney transplant

Background The mechanism by which hypophosphataemia develops following kidney transplantation remains debated, and limited research is available regarding risk factors. This study aimed to assess the association between recipient and donor variables, and the severity of post-transplantation hypophosphataemia. Methods We performed a single-centre retrospective observational study. We assessed the association between demographic, clinical and biochemical variables and the development of hypophosphataemia. We used linear regression analysis to assess association between these variables and phosphate nadir. Results 87.6% of patients developed hypophosphataemia. Patients developing hypophosphataemia were younger, had a shorter time on renal replacement therapy, were less likely to have had a parathyroidectomy or to experience delayed graft function, were more likely to have received a living donor transplant, from a younger donor. They had higher pre-transplantation calcium levels, and lower alkaline phosphatase levels. Receipt of a living donor transplant, lower donor age, not having had a parathyroidectomy, receiving a transplant during the era of tacrolimus-based immunosuppression, not having delayed graft function, higher pre-transplantation calcium, and higher pre-transplantation phosphate were associated with lower phosphate nadir by multiple linear regression. Conclusions This analysis demonstrates an association between variables relating to better graft function and hypophosphataemia. The links with biochemical measures of mineral-bone disease remain less clear.
