Clinical Guideline of Medical and Pediatric Complications after Kidney Transplantation

17

Post-Kidney Transplant Hypertension • BP should be less than 130/80 mmHg in kidney transplant recipients

with CKDT (grade B) • First line anti-hypersensitive drugs should be ACE-I and/or ARB

(grade B)

(Evidence IVa)

New Onset Diabetes Mellitus After Kidney Transplantation(NODAT)

!!!• NODAT is mainly caused by immunosuppressive agents,

such as steroid and CNI (tacrolimus and cyclosporine) !• Minimization or withdrawal of steroid and Monitoring of

blood level of CNI are critically important. !

• NODAT should be managed by a team (transplant physician, endocrinologist for DM, staff Ns, and Dietitian)

FBS < 130mg/dLBS 2hrs after meal < 180mg/dL

HbA1c < 6.5%

NODAT and DM

21

(Evidence IVa)

The risks of Ischemic heart disease are 2.78 times (male) and 5.4 times (female) in kidney Tx recipients with DM, compared to those without DM.

Patient survival is worse in recipients with NODAT than those without NODAT

(Evidence IVa)

Dyslipidemia• LDL-C <120mg/dl !

• LDL-C < 100mg/dl (recipients with CVD) !

• Dyslipidemia should be treated with improvement of life style and then medicine. !

• Statin is first line medicine.

Graft Survival in Non-obese and Obese Transplant Recipients

26

• 56 patients had deceased donor kidney transplantation with 28 pairs.

!• one kidney from the pair into

an obese patient • the other kidney into a non-

obese patient.
