Objective:
To compare low and high MELD scores and investigate whether existing renal dysfunction has an effect on transplant outcome.
Methods:
Data was prospectively collected among 237 liver transplants (216 patients) between March 2003 and March 2009. Patients with cirrhotic disease submitted to transplantation were divided into three groups: MELD > or = 30, MELD < 30, and hepatocellular carcinoma. Renal failure was defined as a +/- 25% decline in estimated glomerular filtration rate as observed 1 week after the transplant. Median MELD scores were 35, 21, and 13 for groups MELD > or = 30, MELD < 30, and hepatocellular carcinoma, respectively.
Results:
Recipients with MELD > or = 30 had more days in Intensive Care Unit, longer hospital stay, and received more blood product transfusions. Moreover, their renal function improved after liver transplant. All other groups presented with impairment of renal function. Mortality was similar in all groups, but renal function was the most important variable associated with morbidity and length of hospital stay.
Conclusion:
High MELD score recipients had an improvement in the glomerular filtration rate after 1 week of liver transplantation.
Insights
High Model for End-Stage Liver Disease (MELD) scores in liver transplant recipients correlate with improved renal function post-transplant. However, these patients experienced longer intensive care unit stays and hospitalizations.
Area of Science:
- Hepatology
- Nephrology
- Transplant Surgery
Background:
- Liver transplantation is a critical treatment for end-stage liver disease.
- Pre-transplant renal function is a significant predictor of post-transplant outcomes.
- The Model for End-Stage Liver Disease (MELD) score is a key determinant for liver transplant allocation.
Purpose of the Study:
- To compare outcomes between liver transplant recipients with low versus high MELD scores.
- To determine the impact of pre-existing renal dysfunction on liver transplant success.
- To evaluate renal function changes after liver transplantation in relation to MELD scores.
Main Methods:
- Prospective data collection from 237 liver transplants (216 patients) between 2003 and 2009.
- Patients categorized into three groups: MELD ≥ 30, MELD < 30, and hepatocellular carcinoma.
- Renal failure defined as a ≥ 25% decline in estimated glomerular filtration rate (eGFR) one week post-transplant.
Main Results:
- High MELD score recipients (≥ 30) showed improved renal function post-transplant.
- These recipients required more ICU days, longer hospital stays, and received more blood transfusions.
- Other groups experienced renal function impairment; mortality was similar across all groups.
- Renal function was the primary factor influencing morbidity and hospital stay duration.
Conclusions:
- Liver transplant recipients with high MELD scores experience improved glomerular filtration rate within one week post-transplantation.
- Despite improved renal function, high MELD score patients face increased short-term resource utilization.
- Renal function post-transplant is a critical determinant of overall patient outcomes and recovery trajectory.
