Overview
What Is Autoimmune Hepatitis?
Autoimmune hepatitis is a long-term liver disease in which the immune system mistakenly attacks healthy liver cells. This immune attack causes inflammation that can gradually lead to liver scarring if it is not treated. Autoimmune hepatitis may develop at any age and can affect people of any sex. It is not contagious, so it cannot spread from one person to another.
Symptoms
Autoimmune Hepatitis Symptoms
Autoimmune hepatitis symptoms can range from mild to severe, and some people have few or no symptoms at first. Symptoms may appear gradually or begin suddenly when liver inflammation becomes active. The severity of symptoms does not always show how much inflammation or scarring is present.
- Ongoing tiredness or fatigue
- Yellowing of the skin or eyes (jaundice)
- Dark-colored urine
- Pale or clay-colored stools
- Itchy skin (pruritus)
- Pain or discomfort in the upper right abdomen
- Nausea or loss of appetite
- Joint pain (arthralgia)
- Skin rash
- Unexplained weight loss
Seek prompt care
Symptoms that should not be ignored
Sudden worsening jaundice, confusion, severe vomiting, or unusual bleeding needs urgent medical attention. These symptoms may signal serious liver dysfunction and should not be watched at home.
Causes
What Causes Autoimmune Hepatitis?
The exact cause of autoimmune hepatitis is not known. A person may have genetic susceptibility that makes the immune system more likely to misidentify liver cells as harmful, with environmental exposures, infections, or certain medicines possibly acting as triggers. These factors do not mean that someone caused the disease through their actions. Autoimmune hepatitis is not a contagious infection and cannot be acquired through ordinary contact with another person.
| Condition | How it develops | Contagious? |
|---|---|---|
| Autoimmune hepatitis | The immune system mistakenly attacks liver tissue; the exact trigger is often unknown. | No |
| Viral hepatitis | A hepatitis virus infects and inflames the liver. | Some types can spread, depending on the virus and route of exposure. |
| Alcohol-related liver disease | Repeated heavy alcohol exposure damages liver cells over time. | No |
Risk Factors
Risk Factors for Autoimmune Hepatitis
Risk factors are characteristics associated with a higher likelihood of autoimmune hepatitis, but they do not prove that someone will develop it. Many people with this autoimmune liver disease have no identifiable risk factor. A healthcare professional must consider the complete medical history rather than relying on one association.
- Being female is associated with a higher likelihood of autoimmune hepatitis.
- A family history of autoimmune disease may indicate inherited susceptibility.
- Having another autoimmune condition, such as thyroid disease, rheumatoid arthritis, or inflammatory bowel disease, may increase risk.
- The disease can occur at any age, including childhood, adulthood, and later life.
- Some people develop autoimmune hepatitis during younger adulthood, while others develop it after age 40.
- A personal history of immune-system disorders may be associated with autoimmune hepatitis.
Complications
Complications of Autoimmune Hepatitis
Untreated or poorly controlled inflammation can cause fibrosis, which is a buildup of scar tissue, and may eventually lead to cirrhosis. Effective treatment can reduce inflammation and lower the risk of progression. The disease itself and its complications are separate from possible side effects of medicines used to control it.
- Cirrhosis, or advanced permanent scarring of the liver.
- Portal hypertension, which is increased pressure in the vein leading to the liver.
- Ascites, or a buildup of fluid in the abdomen.
- Gastrointestinal bleeding from enlarged veins or other effects of portal hypertension.
- Liver failure, in which the liver can no longer perform essential functions adequately.
- A higher risk of liver cancer, particularly when cirrhosis is present.
Diagnosis
How Autoimmune Hepatitis Is Diagnosed
No single test proves that a person has autoimmune hepatitis. Clinicians first consider and exclude other causes of liver inflammation, including viral hepatitis, medication-related injury, metabolic disease, and other liver conditions. Diagnosis combines the medical history, symptoms, examination, blood tests, imaging, and sometimes a liver biopsy.
- Liver enzyme and liver function tests help show inflammation and how well the liver is working.
- An immunoglobulin G test may show increased levels that support an autoimmune process.
- Autoantibody testing may include antinuclear antibodies (ANA) and smooth muscle antibodies (SMA).
- Viral hepatitis testing helps exclude infectious causes of liver inflammation.
- Liver imaging, such as ultrasound or another scan, evaluates the liver and nearby structures.
- A liver biopsy may be used when the diagnosis remains uncertain or to assess inflammation and scarring.
What Autoimmune Hepatitis Laboratory Results Can Show
Autoimmune hepatitis antibodies and liver-test patterns can support a diagnosis, but they cannot establish it by themselves. Results must be interpreted alongside symptoms, examination findings, imaging, and other possible causes of liver injury. An autoimmune hepatitis ICD-10 code is an administrative classification used for records and billing, not a laboratory result or a substitute for diagnosis.
Treatment & Management
Autoimmune Hepatitis Treatment and Management
Autoimmune hepatitis treatment aims to quiet the immune attack, reduce inflammation, normalize liver tests, prevent scarring, and maintain remission. Treatment is individualized according to disease severity, other health conditions, pregnancy considerations, medication tolerance, and response to therapy. Long-term follow-up is usually needed because inflammation can return when treatment is reduced or stopped.
INITIAL TREATMENT
Corticosteroids such as prednisone, and in selected cases budesonide, are used to reduce active liver inflammation. The goal is to improve symptoms and liver tests while limiting further liver injury.
LONG-TERM MANAGEMENT
Steroid-sparing medicines such as azathioprine, or other alternatives when appropriate, may help maintain remission or reduce steroid exposure. Regular laboratory monitoring, adherence, and early discussion of side effects help prevent relapse.
Medication safety
Use treatment only under specialist guidance
Do not start, stop, or taper prednisone or another corticosteroid without medical guidance. Clinicians may monitor bone health, blood glucose, blood pressure, infection risk, weight, and other medication effects during treatment.
People with severe disease, an inadequate response to medicines, or advanced liver failure may need referral to a liver specialist and consideration of additional immune-suppressing treatment. Liver transplantation may be considered when liver failure cannot be controlled or when advanced cirrhosis causes serious complications. A hepatologist can help coordinate medication changes, monitoring, and transplant evaluation when needed.
Outlook and Prognosis
Outlook and Prognosis for Autoimmune Hepatitis
Autoimmune hepatitis is usually manageable rather than quickly curable. Many people can achieve remission when inflammation is diagnosed early and controlled with treatment, although some need long-term medicine and monitoring. Outcomes are generally better before advanced scarring or liver failure develops. The autoimmune liver disease life expectancy of an individual depends on treatment response, adherence, liver damage, and complications.
Treatment response
How well liver inflammation responds to therapy
Medication adherence
Taking treatment and attending recommended monitoring
Liver scarring
The amount of fibrosis or cirrhosis present
Complications
Whether portal hypertension, liver failure, or other problems develop
When Should You See a Doctor
When Should You See a Doctor?
Contact a healthcare professional about persistent fatigue, jaundice, dark urine, pale stools, unexplained itching, abdominal swelling, or abnormal liver tests. Evaluation is especially important if you have another autoimmune condition or take medicines or supplements that may affect the liver. These symptoms do not prove autoimmune hepatitis, but they deserve appropriate testing.
Get urgent medical help
Possible signs of serious liver problems
Seek urgent care for confusion, extreme sleepiness, vomiting blood, black stools, severe abdominal swelling, rapidly worsening jaundice, or fainting. These can be warning signs of serious liver dysfunction or internal bleeding.
