Hyperuricosuria is a condition in which there are high levels of uric acid in urine. It occurs in 15 - 20% of people (mostly men) with calcium oxalate stones. Urate, the salt formed from uric acid, creates the center of a crystal (nidus), around which calcium oxalate crystals form and grow.
Other causes of elevated liver enzymes may include: 1  Alcoholic hepatitis (severe liver inflammation caused by excessive alcohol consumption) 2  Autoimmune hepatitis (liver inflammation caused by an autoimmune disorder)  Celiac disease (small intestine damage caused by gluten)
10 Causes of Elevated Liver Enzymes. Elevated liver enzymes are a marker of inflammation or damage to liver cells. Inflamed or injured liver cells cause the liver enzymes alanine transaminase (ALT) and aspartate transaminase (AST) to leak into the bloodstream. Mild elevations of ALT and AST are commonly discovered in individuals with no symptoms during routine blood work.
