Lactate-free AARC ACLF Score (LaFAS) - A Simple Userfriendly Score is the Best Prognostic Marker for Patients with Alcohol Induced ACLF in Western Indian Population in a Nontransplant Resource-limited Setting.

INTRODUCTION

Acute-on-Chronic liver failure (ACLF) is a disease with a distinct spectrum of liver injury, with a rapid downhill course Here we describe three new scores - Albumin Bilirubin Index (ALBI), platelet albumin bilirubin index (PALBI) and Lactate-free AARC ACLF score(LaFAS), in predicting short-term mortality in patients with alcohol induced ACLF when compared to standard validated scores.

METHODS

Consecutive patients diagnosed as alcohol induced ACLF as per the APASL 2014 definition were included in the study. Standard scores - MELD, MELD-Na, Maddreys' discriminant function, CLIF-OF and CLIF-C ACLF scores, APACHE II, ALBI, PALBI and LaFAS were calculated. The endpoints of the study were to predict short term mortality in alcohol induced ACLF patients using ALBI, PALBI and LaFAS and finding the cut-offs of these new scores and comparing it with standard validated scores.

RESULTS

67 patients were studied with 97% being male. Mean age was 45.78 + 8.15 years.44 patients died. The cut-offs, area under the ROC curve; sensitivity and specificity, positive and negative predictive values of the new prognostication scores were, respectively: ALBI (-0.57; 0.948; 90.9% and 82.6%; 77.69% and 93.15%),LaFAS(7; 0.968; 95.5% and 96.7%; 95.075 and 96.99%), PALBI(-0.28; 0.59; 61.4% and 52.2%; 46.13% and 66.98%). LaFAS and ALBI outnumbered the valid prognostic scores in predicting short-term mortality. PALBI underperformed when compared to all other scores.

CONCLUSION

Thus incorporating albumin and bilirubin in a mathematical equation (for ALBI) or combining it with creatinine and grade of hepatic encephalopathy (for LaFAS) would help in prognosticate the patients with ACLF on admission in a resource limited setting thus enabling them to be transferred to a transplant center.
