Elevated Alanine Aminotransferase in Football Players

Authors: Viroj Wiwanitkit, MADA


To the Editor:

I read the recent publication by Selden et al1 with great interest. The abnormalities of laboratory investigation among the football players, who are externally very healthy and correlation to cardiometabolic disorder is of interest. This report can imply the observation of the occult pre-clinical abnormalities among the healthy athletes and address the health screening for all. Focusing on the aberration of alanine aminotransferase, the actual cause is of interest. The alcohol usage, over the counter drug usage, as well as occult viral hepatitis should be clarified. In addition, there are also many possible underlying practices that can be the cause of cardiometabolic disorder, obesity and insulin resistance.
