Autoimmune Hepatitis

Autoimmune hepatitis is a chronic liver disease where the body’s immune system attacks liver cells, causing inflammation and damage. This can lead to serious health problems if not managed properly.

What is Autoimmune Hepatitis?

Autoimmune hepatitis is a condition where the immune system, which normally defends the body against bacteria and viruses, mistakenly attacks the liver. This results in liver inflammation and, over time, can lead to liver scarring (cirrhosis) and liver failure.

Types of Autoimmune Hepatitis

There are two main types of autoimmune hepatitis:

Type 1 Autoimmune Hepatitis

This is the most common form and can occur at any age. It often affects women and is typically associated with other autoimmune disorders, such as thyroiditis or rheumatoid arthritis.

Type 2 Autoimmune Hepatitis

This type is less common and usually affects children and young adults. It is also more severe and harder to treat compared to Type 1.

Causes of Autoimmune Hepatitis

The exact cause of autoimmune hepatitis is unknown, but it is believed to involve a combination of genetic and environmental factors. Potential triggers include:

---

Symptoms of Autoimmune Hepatitis

Symptoms can vary from mild to severe and might develop slowly or suddenly. Common symptoms include:

---

Diagnosis of Autoimmune Hepatitis

Diagnosing autoimmune hepatitis involves several steps and tests:

Medical History and Physical Examination

Your doctor will start by reviewing your medical history and performing a physical examination to check for signs of liver disease.

Blood Tests

Blood tests are essential to measure liver enzyme levels and to check for antibodies that indicate an autoimmune disorder. Common tests include:

Liver Biopsy

A liver biopsy involves taking a small sample of liver tissue to examine under a microscope. This helps confirm the diagnosis and assess the extent of liver damage.

Stages of Autoimmune Hepatitis

Autoimmune hepatitis progresses through several stages:

Stage 1: Inflammation

In the initial stage, the liver is inflamed but not yet scarred. Symptoms may be mild or absent.

Stage 2: Fibrosis

As inflammation persists, the liver begins to develop scar tissue (fibrosis). Symptoms may become more noticeable.

Stage 3: Cirrhosis

In this stage, extensive scarring disrupts liver function. Symptoms are usually severe, and there is a high risk of liver failure.

Stage 4: Liver Failure

The final stage is liver failure, where the liver can no longer perform its essential functions. This is life-threatening and may require a liver transplant.

Treatment Options for Autoimmune Hepatitis

Treatment aims to reduce liver inflammation, suppress the immune system, and prevent further liver damage. Common treatments include:

Medications

Corticosteroids

Drugs like prednisone are commonly used to reduce inflammation and suppress the immune system.

Immunosuppressants

Medications such as azathioprine or mycophenolate mofetil help reduce the immune system’s attack on the liver.

Liver Transplant

In severe cases where the liver is extensively damaged, a liver transplant may be necessary.

Lifestyle Changes

Making lifestyle changes can help manage symptoms and improve overall health. These include:

Life Expectancy with Autoimmune Hepatitis

With proper treatment, many people with autoimmune hepatitis can lead normal, healthy lives. However, the life expectancy can vary depending on the disease's severity and how well it is managed. Early diagnosis and treatment are crucial for the best outcomes.

Prevention of Autoimmune Hepatitis

While there is no sure way to prevent autoimmune hepatitis, you can take steps to protect your liver and overall health:
