Liver transplantation waiting list
Patients waiting for liver transplantation with chronic end staged liver disease
The only current definitive treatment for end-stage liver disease is transplantation. Due to the scarcity of organs available, the correct prioritization of patients for liver transplantation has a crucial importance. Nowadays, patients are ranked according to severity of liver disease, measured by the MELD score. This index is only derived from objective measures (serum concentration of bilirubin, creatinine and INR). Hepatic encephalopathy (HE) is a serious and progressive disorder in patients with end-stage liver disease. The severity of HE has prognostic implications in those waiting for liver transplantation. However, the prognosis of HE is independent and not correlated to the MELD score. Hepatic encephalopathy triggers multiple changes in brain magnetic resonance imaging (MRI) providing an objective way to evaluate it. Also electroencephalogram and neuropsychological evaluation might increase mortality prediction.
Adding the information provided by MRI, electroencephalogram and neuropsychological evaluation to the MELD score model might increase the prediction of mortality. Increase mortality's prediction has a fundamental importance because in organ allocation.
We will evaluate the predictive value of these variables in predicting mortality of those patients waiting for liver transplantation.
