Drought can also have significant impacts on the economy. For example, in the first year of a severe drought from 2007 to 2009, the U.S. Southeast lost over $1.3 billion due to destruction of major crops such as corn, wheat, soybeans, cotton, and hay.
Less common causes include Î±1-antitrypsin deficiency, autoimmune hepatitis, and Wilson disease. Extrahepatic conditions (e.g., thyroid disorders, celiac disease, hemolysis, muscle disorders) can also cause elevated liver transaminase levels.
Tumors affecting the gall bladder, liver or bile ducts could be responsible for elevated levels. An allergic reaction to the blood received during a transfusion can also cause the levels of bilirubin to rise in adults. Cirrhosis of the liver is another reason for elevated bilirubin levels.
