This study sought to determine the prevalence of significant liver disease in those subjects with serum alanine aminotransferase levels in the range between the current and the newly suggested upper limit of normal (termed the delta range). The files of the previous study subjects (who underwent at least one alanine aminotransferase measurement in 2002 and followed to 2012) were reviewed for a diagnosis of chronic liver disease; aspartate aminotransferase/platelet ratio index, FIB-4 and alanine aminotransferase/aspartate aminotransferase ratio were used to evaluate liver fibrosis. The prevalence of significant liver disease, by diagnoses and fibrosis scores was compared between subjects with alanine aminotransferase levels in the delta range (men, 42-45 IU/L; women, 26-34 IU/L) and in the newly suggested normal range (men, 15-42 IU/L; women, 10-26 IU/L). The cohort included 49,634 subjects (41% male, mean age 83±6 years) of whom 2022 were diagnosed with chronic liver disease including 366 with cirrhosis. Compared to subjects with alanine aminotransferase levels in the newly suggested normal range, subjects with alanine aminotransferase levels in the delta range had a significantly higher rate of chronic liver disease (men, 15.3% vs. 4.9%; women, 7.8% vs. 3.3%) and of cirrhosis specifically (men, 4.2% vs. 0.9%; women, 1.5% vs. 0.4%) and also had higher mean fibrosis scores (P <0.001 for all). Lowering the current upper limit of normal of serum alanine aminotransferase may help to identify elderly patients at risk of significant liver disease.

Liver biopsy is the reference method for antiviral therapy decision making in chronic hepatitis B (CHB) when alanine aminotransferase (ALT) is less than two times of upper limit of normal (
The association of serum liver enzyme levels with all-cause mortality in individuals without hepatitis B virus or hepatitis C virus infection is inconsistent. We aimed to investigate all-cause and non...
Does turmeric/curcumin supplementation improve serum alanine aminotransferase and aspartate aminotransferase levels in patients with nonalcoholic fatty liver disease? A systematic review and meta-analysis of randomized controlled trials.
We performed a meta-analysis to evaluate the efficacy of turmeric/curcumin supplementation on serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in patients with nonalcoholic fa...
Chronic liver inflammation caused by chronic hepatitis B virus (CHB) infection leads to liver cirrhosis and hepatocellular carcinoma. Recently, the role of alanine aminotransferase (ALT) as a predicto...
It was recently reported that lactate acts as a metabolic mediator and rises in the diabetic state, but the physiological effects are as yet poorly understood. The objective of the current study was t...
Patients with chronic hepatitis C with persistently normal alanine aminotransferase (ALT) levels have been generally excluded from treatment, because the strong conviction that normal ALT ...
Laboratory change induced by common bile duct (CBD) stone is in general observed as the higher elevation of alkaline phosphatase (ALP) and gamma-glutamyl transpeptideas (ɤ-GT), in compari...
The aim of this study was to assess the lipid-lowering activity and safety of a dietary supplement containing monacolin K, L-arginine, coenzyme Q10 and ascorbic acid (vitamin C). Twenty b...

Severe inability of the LIVER to perform its normal metabolic functions, as evidenced by severe JAUNDICE and abnormal serum levels of AMMONIA; BILIRUBIN; ALKALINE PHOSPHATASE; ASPARTATE AMINOTRANSFERASE; LACTATE DEHYDROGENASES; and albumin/globulin ratio. (Blakiston's Gould Medical Dictionary, 4th ed)
An inherited autosomal dominant trait characterized by abnormally elevated levels of total serum THYROXINE; (T4) in euthyroid patients with abnormal SERUM ALBUMIN that binds T4 with enhanced affinity. The serum levels of free T4, free T3, and TSH are normal. It is one of several T4 abnormalities produced by non-thyroid disorder. This condition is due to mutations of the ALB gene on CHROMOSOME 4.
