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)
According to the Mayo Clinic and the Johns Hopkins Children's Center, causes of elevated liver enzymes in children include viral infections and overdose of certain medications. If your child is obese or has a diet high in fatty foods, elevated liver enzymes may result and are an indication of fatty liver disease.
