Renal dysfunction is common in LT candidates; however, predicting post-LT renal recovery is sometimes difficult. Kidney biopsy is helpful in identifying reversible renal injury but is associated with significant risks.
Aim: identify non-invasive method to predict post-LT renal recovery.
Methods:129 LT candidates with renal dysfunction of unknown cause (defined as iothalamate GFR <40 ml/min) and/or proteinuria underwent percutaneous kidney biopsy at time of LT evaluation. Patients with ≥30% interstitial fibrosis (IF) and/or ≥30-40% glomerulosclerosis (GS) were listed for simultaneous liver-kidney transplantation (SLK) while patients with lesser degrees of IF/GS were listed for LT alone. Prior to kidney biopsy, 24-hr urine protein and sodium excretions along with systolic and diastolic blood pressures (SBP and DBP, respectively) were measured. The use of anti-hypertensive medications other than diuretics was recorded.
Results: 73 (57%) patients were listed for LT and 56 were listed for SLK. Table 1 lists the clinical and histological findings of the 2 groups.
|Listed for LT n=73||Listed for SLK n=56||P|
|% Hepatitis C||41||44||0.4|
|% previous LT||17||29||0.3|
|% Diabetes mellitus||22||25||0.1|
|% on BP medications||9||27||0.01|
|Iothalamate GFR (ml/min)||30±17||26±11||0.1|
|% dialysis at biopsy||16||14||0.7|
|24-hr urine protein (mg/d)*||56 (0-5406)||135 (0-5604)||0.2|
|24-hr urine sodium (mEq/d)*||57 (0-289)||76 (0-238)||0.3|
