Abstract
Introduction

Variceal upper gastrointestinal bleeding is a common cause of decompensation in patients with liver cirrhosis. While mortality data, which are from 10 to 15%, are available, there are no validated scales to predict in-hospital mortality in this patient population.

Objective

To determine whether the MELD-Lactate (MELD-LA) level is associated with in-hospital mortality in patients with chronic liver disease who are admitted for variceal bleeding.

Material and methods

A prospective, observational, and analytical study was conducted that included 120 patients. The MELD-LA cut-off point was obtained, and in-hospital mortality was obtained using conventional prognostic scales that had the highest sensitivity and specificity for comparison purposes. Additionally, a survival analysis was performed using the MELD-LA cut-off point obtained.

Results

In our cohort, 6 (5.0%) patients died during hospitalization. Patients who died had a mean MELD-LA value of 20.0 (±4.97) as opposed to those who did not die, 13.62 (±3.29), (p<0.001). The MELD-LA cut-off point of >14.0, with a sensitivity of 100%, a specificity of 71.0%, a positive predictive value of 15.4%, a negative predictive value of 100.0%, and an AUC (area under the curve) of 0.886, was most well correlated with higher in-hospital mortality. Survival was 71.1% in patients with MELD-LA levels>14.0 versus 100.0% in those with lower levels (p=0.001) during hospitalization.

Conclusion

The measurement of MELD-LA at admission seems to be a good complementary marker for the evaluation and prognosis of in-hospital mortality in patients with liver cirrhosis, and variceal upper gastrointestinal bleeding.

Resumen
Introducción

El sangrado de tubo digestivo alto variceal es una causa frecuente de descompensación en pacientes con cirrosis hepática. La mortalidad estimada en estos pacientes es del 10-15%, y a la fecha no se cuenta con escalas validadas para predecir la mortalidad a corto plazo.

Objetivo

Determinar si el nivel de MELD-lactato (MELD-LA) medido durante la admisión hospitalaria se asocia con mayor mortalidad intrahospitalaria en pacientes con hepatopatía crónica que ingresan por sangrado de tubo digestivo alto variceal.

Material y métodos

Se realizó un estudio prospectivo, observacional y analítico que incluyó 120 pacientes. Se obtuvo el punto de corte de MELD-LA sérico y de las escalas pronósticas convencionales que predecían con mayor sensibilidad y especificidad la mortalidad intrahospitalaria. Además, se realizó un análisis de supervivencia utilizando el punto de corte de MELD-LA.

Resultados

Seis (5,0%) pacientes fallecieron durante la hospitalización. Los pacientes que fallecieron tuvieron un valor medio de MELD-LA de 20,0 (±4,97), frente a 13,62 (±3,29) de los que no murieron (p<0,001). El punto de corte para MELD-LA que mejor se correlacionó con mortalidad intrahospitalaria fue>14,0, con una sensibilidad del 100%, una especificidad del 71,0%, un valor predictivo positivo del 15,4%, un valor predictivo negativo del 100,0% y un área bajo la curva de 0,886. La supervivencia durante la hospitalización fue del 71,1% en pacientes con niveles de MELD-LA>14,0 frente al 100,0% en aquellos con niveles menores (p=0,001).

Conclusión

La medición de MELD-LA al ingreso parece ser un buen marcador complementario para la evaluación y pronóstico de mortalidad intrahospitalaria en los pacientes con cirrosis hepática y sangrado de tubo digestivo alto variceal.
