Título

Changes in body mass index and outcomes after kidney transplantation: a single centre, retrospective, observational study

Introdução

The aim of this study was to describe the changes in body mass index (BMI) after kidney transplantation and assess how this influences long-term outcomes.

Material e Método

Data were collected for all kidney transplant recipients between January 2007 and July 2016. Changes in BMI over the post-transplant period were modelled using a generalised estimating equation. The change in BMI from pre-transplantation to six months was then calculated for each patient. These were categorised into three groups: stable BMI (a change of ±1.5 kg/m2), BMI reduction and BMI increase (changes of >1.5 kg/m2), between which a range of outcomes were compared.

Resultados

Data was available for 1,344 patients, who had a geometric mean pre-transplant BMI of 27.3 kg/m2. This declined significantly (P0.05).

Discussão e Conclusões

Our data demonstrates that BMI significantly reduces in the first month after kidney transplantation, before increasing to pre-transplant levels at 3-5 years. Furthermore, patients with decreasing BMI at six-months have impaired graft function in the long-term. These observations conflict with the existing literature and warrant further investigation
