Is ANA elevated in autoimmune hepatitis?
About 50–75% of AIH patients are ANA-positive (with or without anti-SMA) (24). ANA can also be detected in healthy persons or patients with other liver diseases such as fatty liver disease, drug-induced liver injury (DILI) disease, or viral hepatitis.
Can hepatitis cause a positive ANA?
Background: Serum autoantibodies such as antinuclear antibody (ANA) are frequently detected in patients with chronic hepatitis C virus (HCV) infection, but its relevance is a matter of discussion.
What labs are abnormal with autoimmune hepatitis?
Your doctor will use blood tests to look for evidence of autoimmune hepatitis. Blood tests include tests that check levels of the liver enzymes alanine transaminase (ALT) and aspartate transaminase (AST) and check for autoantibodies such as antinuclear antibody (ANA) and anti-smooth muscle antibody (SMA).
Can a fatty liver cause a positive ANA?
LEARNING POINTS. Up to 30% of patients with non-alcoholic fatty liver disease (NAFLD) may have antinuclear antibodies (ANA).
Is autoimmune hepatitis A form of lupus?
When lupus causes hepatitis, it’s called autoimmune hepatitis. This means that your immune system is attacking your liver. There are 2 types of autoimmune hepatitis: Type 1 is more common, and affects people of all ages.
What causes positive ANA besides autoimmune disease?
Causes of a false-positive ANA include infection, malignancy, and certain medications. Therefore, a positive ANA test does not equal a diagnosis of lupus or any autoimmune or connective tissue disease.
What diseases cause high ANA levels?
Conditions that usually cause a positive ANA test include:
- Systemic lupus erythematosus.
- Sjögren’s syndrome — a disease that causes dry eyes and mouth.
- Scleroderma — a connective tissue disease.
- Rheumatoid arthritis — this causes joint damage, pain, and swelling.
- Polymyositis — a disease that causes muscle weakness.
