Abstract
BACKGROUND: New-onset diabetes after transplantation (NODAT) is a serious complication which runs the risk of infections, morbidity and mortality. OBJECTIVE: To evaluate M235T and T174M polymorphisms of angiotensinogen gene along with some demographic and clinical factors including age; sex; body mass index (BMI); model for end-stage liver disease (MELD) score; prednisolone, mycophenolate mofetil and tacrolimus dose; and serum level in NODAT among liver recipients. METHODS: In this study 115 patients (53 with and 62 without NODAT) who had no history of diabetes before the transplantation were investigated. Furthermore, 80 randomly selected apparently healthy people (no transplantation) were used as the control group. Two angiotensinogen polymorphisms (M235T and T174M) were studied using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). RESULTS: Patients included 68 (59.1%) females and 47 (40.9%) males; they had a mean±SD age of 37.4±16.9 years. The M allele frequency was 55.7% (n=128) in M235T and 20.0% (n=46) in T174M polymorphisms. Binary logistic regression analysis confirmed that age (p=0.005), prednisolone dose (p<0.001) and mutated M235T polymorphism (p=0.003) were independent risk factors. CONCLUSION: Presence of M235T T allele may significantly (p<0.001) increase the NODAT risk, and increase the likelihood of developing end-stage liver disease (p=0.003). T174M T allele had a significantly (p=0.007) higher frequency in NODAT group.
