The growth hormone/IGF-1 axis is a risk factor for long-term kidney allograft failure.

ABSTRACT: INTRODUCTIONMaladaptive hypertrophy, podocyte stress, and depletion contribute to kidney function decline. Although insulin-like growth factor 1 (IGF-1) plays a key role in early hypertrophic responses in the single kidney state, its impact on kidney transplant (KTx) outcomes remains uncertain. This report tests the hypothesis that early IGF-1 exposure reduces KTx survival. METHODSPopulation datasets compared incident death-censored graft failure (DCGF) rates by age at KTx (n = 366,404) with IGF-1 levels by age (n = 15,014). A clinical study of 216 KTx recipients evaluated the association of IGF-1 exposure with DCGF and secondary outcomes of proteinuria and biopsy-proven acute rejection. IGF-1 exposure was modeled using pre-KTx IGF-1 levels and donor kidney dose estimated from the donor/re
