Background. The evolution and association between body composition and glucose haemostasis after kidney transplantation has not been elucidated.
Methods. We investigated 150 consecutive patients without suspected diabetes 8-10 weeks after kidney transplantation and subsequently after one year. Oral glucose-tolerance tests and dual-energy x-ray absorptiometry (DXA) scans were performed. Body mass composition including VAT assessments were measured from DXA scans with a novel validated software.
Insulin levels in plasma were measured and resistance indexes (HOMA-IR) and insulin release indexes (HOMA-ß) were calculated.
Results. Median body weight increased from 74,5 to 76,9 kg (P<0.001) and total fat mass increased from 22,4kg to 25,0kg to (P<0.001) whereas bone mass and visceral fat mass remained unchanged (P <0.638 and P<0.13, respectively). Glucose metabolism improved after one year despite an increase in body fat and BMI . At baseline 13% of patients had PTDM, 19% had IGT and 68% had NGT. After one year 9% of patients had PTDM, 11% had IGT and 80% NGT. Insulin resistance index, HOMA-IR and insulin release index, HOMA-ß index remained unchanged.We addressed demographic and other baseline data that were potentially associated with a normal glucose tolerance after one year in a multivariate model. VAT percentage of fat <5% (HR=3.1, P=0.013), prednisolone dose <10 mg day (HR 3.9, P=0.013), age in the lower quartile (HR 3.2, P=0.047), and HOMA-IR index in lower quartile (HR=3.0, P= 0.04) were significant factors for prediction of normal glucose tolerance after one year. Body weight, BMI, sex, tacrolimus concentration, HOMA-ß index, use of live donor and preemptive transplantation were not significant predictors.
Conclusions. The body composition of non-diabetes kidney transplant recipients is changed during the first year with weight gain due to increased fat mass without a change in lean body mass. However, visceral fat content is not increased and glucose metabolism is generally improved.
