Low Alanine Aminotransferase Cut-Off for Predicting Liver Outcomes; A Nationwide Population-Based Longitudinal Cohort Study.

ABSTRACT:

Background and aim

Recent practice guidelines suggest healthy normal alanine aminotransferase (ALT) levels should be less than 30 U/L for males and 19 U/L for females. We tried to validate the prediction power of the "low cut off" for liver related outcomes in the general population.

Methods

A total of 426,013 subjects were followed up for 10 years using the National Health Screening Cohort database. Prediction ability of long term mortality and liver related outcomes between conventional (<40 U/L in men and women) and low (<30 U/L in men and <19 U/L in women) ALT cut-off values were compared.

Results

Both conventional and low ALT cut-offs predicted liver related unfavorable outcomes in Kaplan-Meier analysis. Following adjustment for age, body mass index, smoking, exercise, alcohol consumption, fasting blood glucose, and cholesterol via multivariate Cox regression, abnormal ALT using new 'low ALT cut off' was a significant independent predictor for liver-related mortality, HCC, and decompensated liver events. When the low cut-off criteria were added to the prediction model, the ability to predetect liver-related hard outcomes significantly increased in both men and women (p-values < 0.0001). The C-index values for predicting liver-related adverse events were the same in both ALT cut-offs, after adjusting confounding factors (C index value: 0.73~0.88).

Conclusions

New low ALT cut-off showed good prediction power for liver related unfavorable outcomes.

Project description:Liver cirrhotic predisposes patients to coagulopathy and bleeding. Little is known about outcomes of acute myocardial infarction (AMI) in cirrhotic patients.Data from Taiwan National Health Insurance Research Database during 2001 to 2013 were retrieved for patients admitted with cirrhosis and AMI. We excluded patients with missing information, <20 years old, previous AMI, previous coronary intervention, and liver transplant. Patients were separated into cirrhotic and non-cirrhotic. Primary outcomes included all-cause mortality, recurrent myocardial infarction (MI), major cardiac and cerebrovascular events (MACCE: recurrent MI, revascularization, ischemic stroke, and heart failure), and liver outcomes (hepatic encephalopathy, ascites tapping, spontaneous peritonitis, and esophageal varices bleeding).A total of 3217 cirrhotic patients and 6434 non-cirrhotic patients were analyzed, with a mean follow up of 2.8?±?3.3 years. In cirrhotic patients with AMI, subsequent coronary and cerebrovascular events were lower in comparison to non-cirrhotic patients, with higher all-cause mortality observed from adverse liver related outcomes and bleeding. There were significantly lower cumulative incidence of both recurrent MI and MACCE in cirrhotic patients with AMI compared with non-cirrhotic patients with AMI (hazard ratio [HR] 0.82, confidence interval [CI] 0.71-0.94, P?=?.006 and HR 0.86, 95% CI 0.79-0.92, P?<?.001, respectively). There was significantly higher cumulative incidence of liver related outcome in cirrhotic patients with AMI compared with non-cirrhotic patients with AMI (HR 2.27, 95% CI 2.06-2.51, P?<?.001). And there was significantly higher all-cause mortality in cirrhotic patients with AMI compared with non-cirrhotic patients with AMI (HR 1.30, 95% CI 1.23-1.38, P?<?.001).In cirrhotic cohort with AMI, a decreased in coronary and cerebrovascular events were observed. However, these patients also had higher all-cause mortality due to adverse liver outcomes and bleeding.
