Background

NODAT (New onset Diabetes after Transplant) is associated with multiple complications in liver transplant recipients which has to be diagnosed and treated early to prevent graft failure, cardiovascular morbidity and mortality. With improvement in the care of liver transplant recipients, post-transplant survival has significantly increased. With improved survival, incidence of chronic rejection, Diabetes, Hypertension, Dyslipidemia, etc. complications incidence also increasing.

Aims and Objectives

To know the incidence and predictors of NODAT.

Methodology

This was a prospective study of non-Diabetic recipients who underwent Liver Transplantation at Yashoda Hospital, Secunderabad from January 2020 to May 2021. The follow-up duration was 6 months. Total 65 patients were enrolled after excluding recipients who were &lt;18 years of age, were already having diabetes, whose survival was less than 6 months of transplantation and who were not of an Indian origin. All the relevant clinical and biochemical data were collected. Appropriate statistical tests were applied to compare NODAT and Non-diabetes groups (recipients who did not develop diabetes after liver transplantation) to know the predictors of NODAT. Diagnosis of NODAT was be established by the standard ADA guidelines using Fasting blood sugar (FBS), Post prandial blood sugar(PPBS) or HbA1C. Diagnosis of NODAT required the presence of one of the four parameters: (i) fasting blood glucose levels ≥ 126 mg/dL on two occasions OR (ii) Insulin therapy requirement for &gt;= 30 days OR (iii) oral hypoglycemic agent use for ≥ 30 consecutive days OR (iv) HbA1c ≥ 6.5. Transient NODAT was defined as the resolution of hyperglycemia within 6 months of transplantation.

Results

Total incidence of NODAT in our study was 29.2%. Among them 47.36% were transient NODAT and 52.67% were persistent NODAT. Factors significantly associated with occurrence of NODAT were: Type of Transplant (Living donor liver transplant v/s Deceased donor liver transplant), Presence of Impaired fasting glucose (IFG), presence of post-operative hyperglycemia, lower pre-transplant Magnesium & Immediate post-operative Magnesium level, lower post-operative Albumin, higher trough Tacrolimus level at 3 Months, higher Tacrolimus and steroid dose at 3 months. Factors for which association with NODAT could not be found were: Age, Hepatitis C cirrhosis, alcoholic cirrhosis, pre-transplant BMI, baseline MELD score, pre-transplant FBS, donor age, donor gender, donor BMI, donor FBS & Hba1c, donor CT LAI (Liver Attenuation Index, L-S) value, Steroid dose at discharge, immediate post-op trough Tacrolimus level and use of Everolimus.

CONCLUSION: NODAT is the significant entity to be addressed. A robust strategy should be in place for the screening of NODAT. Lower Magnesium levels, presence of pre-transplant IFG and post-operative hyperglycemia give an early opportunity for detection of NODAT. Minimizing Tacrolimus level and steroid dose could be an effective strategy for the prevention of NODAT.
