ABSTRACT
BACKGROUND:
The aim of this study was to determine the appropriate body mass index (BMI) in Japanese kidney transplant (KTx) recipients. We analyzed the effects of pre- and post-transplant (Tx) obesity on graft and patient survival, perioperative complications, post-transplant diabetes mellitus (PTDM), and cardiovascular disease (CVD) in Japanese KTx recipients.METHODS:
This retrospective study included 269 recipients who underwent KTx from 2008 through 2020 at Niigata University Hospital. Obesity was defined as a body mass index (BMI) ≥25 kg/m2. We examined the association between pre- and post-Tx obesity and graft survival, patient survival, the incidence of PTDM and CVD, and perioperative surgical complications.RESULTS:
The graft survival rate was lower in the pre-Tx BMI ≥25 kg/m2 group, although there was no significant difference in patient survival. There was no difference in graft and patient survival between the post-Tx BMI ≥25 kg/m2 group and the <25 kg/m2 group. A pre-Tx BMI ≥25 kg/m2 was an independent risk factor for biopsy-proven allograft rejection. New-onset DM after transplantation was significantly more common in the BMI ≥25 kg/m2 group than in the BMI <25 kg/m2 group (36% vs 13%; P = .002). The incidence of CVD was significantly higher in the post-Tx BMI ≥30 kg/m2 group than in the BMI <30 kg/m2 group (50% vs 11%; P = .023). There were no differences in surgical operating time, intraoperative blood loss, or perioperative complications between the obese and non-obese groups.CONCLUSION:
Pre-Tx BMI ≥25 kg/m2 may be a risk factor for allograft rejection and graft loss. Post-Tx BMI should be <25 kg/m2 to reduce the risk for PTDM.
