Introduction. Glucocorticoids (GCs) are commonly prescribed as immunosuppressive agents after kidney transplantation and their most common non-traumatic adverse effect is Avascular Necrosis (AVN) of the femoral head. In this regard, this study aimed to evaluate the glucocorticoid receptor (GR) polymorphisms among kidney transplant recipients and their potential role as a risk factor for the incidence of AVN. Methods. In this study, 99 renal transplant recipients were evaluated for the correlations of GR polymorphisms including N363S (rs6195), BclI (rs41423247), ER22/23EK (rs6189/rs6190), and A3669G (rs6198) with AVN after renal transplantation. Results. Results showed that none of the renal-transplanted patients neither with GC hypersensitive polymorphisms (N363S and BclI) nor with GC-resistant polymorphisms (A3669G and ER22/23EK) developed AVN (P > .05). In addition, the medications of the renal recipients with AVN were significantly different from the nonAVN patients (P < .001). Conclusion. The study results indicate that the GR polymorphisms have no critical roles in the susceptibility to AVN after renal transplantation. However, further studies to confirm the results are recommended.
