Mycophenolate Mofetil As Frontline And Salvage Therapy
Mycophenolate mofetil, a next generation purine antagonist, has been used as a frontline and salvage therapy for autoimmune hepatitis.34 As a frontline treatment in 59 patients treated for 3 to 92 months , mycophenolate mofetil in combination with prednisolone normalized serum ALT and -globulin levels in 88%, induced a partial laboratory improvement in 12%, allowed the withdrawal of corticosteroids in 58%, and induced treatment-ending side effects in 3% .47 Therapy with mycophenolate mofetil and prednisolone can be effective and safe in treatment-naÃ¯ve patients, but comparative clinical trials with standard therapy are necessary to establish its preference.
Mycophenolate mofetil has also been used as a salvage therapy for patients with corticosteroid-refractory liver disease or azathioprine intolerance.34 Composite analysis of the several, small, single center experiences indicates that mycophenolate mofetil can induce improvement of laboratory tests in 45%, facilitate the withdrawal of corticosteroids in 40%, and cause treatment-ending side effects in 15% .34,50 Outcomes can be improved by using the treatment in a selective fashion. Therapy with mycophenolate mofetil has rescued patients who are azathioprine intolerant more commonly than patients who are refractory to conventional corticosteroid treatment ,34,41,45,46,50 whereas children with autoimmune hepatitis and sclerosing cholangitis have not responded.

Protecting your liver goes a long way when it comes to taking control of your health and longevity. So, order the autoimmune hepatitis panel test to address the damaging threats to your troubled immune system.
Blood Tests For Autoimmune Diseases
Diagnosing autoimmune diseases can be a lengthy process: It can take more than five years to accurately diagnose an autoimmune disease. There is no one test that can diagnose all 80 types of autoimmune diseases.
However, some blood tests can show whether there is an inflammatory process going on in your body, which is a characteristic of autoimmune diseases, and help point the way to the correct diagnosis. More specialized tests are available to pinpoint the exact disease.
This article discusses the various blood tests that may be ordered to diagnose an autoimmune disease, how they’re interpreted, and what information each can provide.

Who Should Get Tested For Autoimmune Hepatitis
Those who exhibited symptoms of liver problems will most likely have to take the autoimmune hepatitis test, especially if they are at a higher risk for the condition.
These risk factors include genetics which suggests that if the autoimmune disease runs in your family, you will have to go through lab work.
Also, those who already have an autoimmune disease like rheumatoid arthritis and celiac disease could also develop autoimmune hepatitis.
What Is Autoimmune Hepatitis
The liver is a large organ that sits up under your ribs on the right side of your belly . It helps filter waste from your body, makes bile to help digest food, and stores sugar that your body uses for energy. Autoimmune hepatitis occurs when your bodys infection-fighting system attacks your liver cells. This causes swelling, inflammation and liver damage.
It is a long-term or chronic inflammatory liver disease.
- May occur at any age
- Affects women more than men
- Is often linked to other diseases where the body attacks itself

How Autoimmune Hepatitis Is Diagnosed
Autoimmune hepatitis is an autoimmune disease that occurs when the bodys immune system attacks the liver by mistake. The exact cause is unknown but believed to be due to a combination of genetic and environmental factors.
There is no one test to diagnose autoimmune hepatitis. The diagnostic process usually involves a physical exam, detailed history, lab tests, imaging studies, and a liver biopsy.

Is There A Cure
Not yet. Since we do not know exactly what causes autoimmune hepatitis, we do not yet have a medical cure for the condition. Steroids and other anti-inflammatory drugs can certainly control the inflammation in the majority of cases. However, in certain patients in whom the inflammation continues or who have not been detected and diagnosed until very late in the course, cirrhosis can occur. Cirrhosis is a condition characterized by increased scar tissue that destroys the normal architecture of the liver.
Even if cirrhosis occurs, patients who have a mild disease without active inflammation generally do well and can live many years or decades without problems. If inflammation continues, the cirrhosis usually worsens, eventually reaching a stage called end-stage liver failure. If this stage has been reached, liver transplantation can be used in some patients to successfully treat the condition.

Can An Autoimmune Hepatitis Diagnosis Be Something Else
Some symptoms and lab findings found in autoimmune hepatitis are also common in other chronic conditions. Your medical team will work to rule out any other possible causes for your symptoms. Some diseases to rule out include other types of hepatitis, certain viral infections, and other liver conditions such as cirrhosis and fatty liver disease.
How Is Autoimmune Hepatitis Diagnosed
Your healthcare provider will look at your health history and give you a physical exam.
Some lab blood tests used to diagnose autoimmune hepatitis include:
- Liver function tests. These check for inflammation or damage to your liver.
- Complete blood count or CBC. Looks at the number and types of cells in your blood.
- Coagulation panel. This test looks at how well the clotting proteins are working.
- Electrolyte panel. Checks to see if you have an electrolyte imbalance.
- Autoimmune antibodies. These are used to see if you have autoimmune hepatitis or another liver disease with similar symptoms.
- Other liver tests. These are done to check for other possible types of liver disease.

Serum Proteins And Immunoglobulins
An immunoglobulin G -predominant polyclonal hypergammaglobulinemia is a common finding in patients with untreated autoimmune hepatitis. Gamma globulin values typically range from 3 to 4 g/dL and frequently are as high as 5-6 g/dL. Cases of hyperviscosity syndrome secondary to high IgG levels have been reported. Autoimmune hepatitis is an unlikely diagnosis in patients who have acute hepatitis without hypergammaglobulinemia.
The gamma globulin or the IgG level may be followed on a regular basis as a marker of disease responsiveness to therapy.
Patients with autoimmune hepatitis type 2 commonly have partial IgA deficiency.
Diagnosing Autoimmune Hepatitis In Children
The liver is a large organ in the abdomen that performs many important tasks: It removes toxins from the blood, makes substances that aid in digestion and blood clotting, and stores vitamins and minerals needed throughout the body.
Hepatitis refers to any inflammation of the liver. Autoimmune hepatitis occurs when the immune system, which normally protects the body from infection, attacks healthy cells in the liver, causing chronic inflammation. Without treatment, this inflammation can cause scarring in the liver, known as cirrhosis, and ultimately, liver failure.
Doctors at Hassenfeld Childrens Hospital at NYU Langone have extensive experience in diagnosing and treating autoimmune hepatitis in children.

Autoimmune Hepatitis & How It Is Diagnosed
Falk: What on earth is autoimmune hepatitis? What do those words really mean?
Darling: Autoimmune hepatitis is a chronic liver disease. It can affect any aged patient, any ethnicity, it can affect either sex, usually has a female-to-male predominance of about 3:1. Hepatitis just means inflammation of the liver.
Falk: Remind me again, what does the liver do?
Darling: The liver does a lot of important things. For one, it metabolizes nutrients from the gut, it makes bile which helps you digest fats, it makes a lot of important proteins, specificallyall of your clotting factors except for one, and proteins that help fluids stay in the right spaces. It also detoxifies certain drugs or medications.
Falk: When you inflame a liver, just like when you inflame any other organ, the suffix is -it is the liver is the hepatic system, so hepatitis which is inflammation of the liver from any number of causes.
Darling: Absolutely. The liver is made up of liver cells or hepatocytes, and its made up of small and large bile ducts, and for the most part it implies that this is inflammation of the liver cells themselves, the hepatocytes. It is usually manifested as elevated liver enzymes, so AST, ALTthese are blood tests and it is reflective of turnover of liver cells.
Falk: The liver can be affected by a number of factors. One can get hepatitis from alcohol, one can get hepatitis from a number of drugs, one can get hepatitis from certain viruses. Whats the most common of those entities?
How To Prepare For Your First Appointment With A Hepatologist
Think through the questions that the doctor may ask you. Schedule some time to sit down and take notes before the appointment. Write down each of your symptoms and how long they have been going on. Think about any family members who have a history of liver disease or autoimmune conditions, and write them down as well. Finally, create a list of all of the medications, vitamins, and supplements you are currently taking.

Revised Original Diagnostic Scoring System Of The Iaihg
The revised original scoring system is a comprehensive template that evaluates 13 clinical categories and renders 27 possible grades .19 This comprehensive scoring system was originally developed as a research tool by which to ensure the homogeneity of patient populations in clinical studies.139 It has emerged subsequently as a template by which to ensure the systematic evaluation of patients, and it can serve as a mechanism by which to bolster clinical judgment.21,140 The scoring system can accommodate deficiencies or inconsistencies in the clinical presentation and support the diagnosis in difficult cases by rendering a composite score before and after corticosteroid treatment.
Calcineurin Inhibitors As Frontline And Salvage Therapies
Cyclosporine has been used successfully as a frontline agent in children and adults with autoimmune hepatitis,36,274,275 but the only randomized clinical trial involving 39 patients has indicated equivalency rather than superiority of cyclosporine therapy to standard combination therapy .51 In the absence of clear advantages that outweigh the risks of treatment and its expense, frontline therapy with cyclosporine cannot be justified.49 Similarly, tacrolimus has also had success as a frontline treatment in 21 patients who improved their serum ALT and AST levels after 3 months.35 The cytopenia and nephrotoxicity that developed in these patients were not treatment-ending, but validation of this regimen by randomized clinical trial has not emerged after 20 years.
Treatment with the calcineurin inhibitors is commonly indefinite, and it requires experience to ensure careful monitoring and appropriate dose adjustment. Cyclosporine has been administered in doses of 2 to 5 mg/kg body weight with dose adjustments to achieve trough levels of 100 to 300 ng/mL,34,36,49 and tacrolimus has been administered at a starting dose of 0.5 to 1 mg daily and increased to 1 to 3 mg twice daily as tolerated to achieve a serum level of 3 ng/mL .34,35,38,49,276,279

Dos And Donts In Managing Autoimmune Hepatitis:
- DO remember that monitoring of your condition is important. Report any new symptoms to your health care provider promptly.
- DO call your health care provider if you notice skin color changes, side effects from medicines, joint pains, or abdominal swelling.
- DONT ignore drug side effects, such as weight gain, anxiety, confusion, thinning of bones , thinning of the hair and skin, diabetes, high blood pressure, and cataracts.
- DONT use alcohol. It may further damage your liver.

Graft Dysfunction After Liver Transplantation
Autoimmune hepatitis can recur or develop de novo after liver transplantation, and it should be considered in all transplanted patients with graft dysfunction .108113 The frequency of recurrence ranges from 8% to 68%, depending in part on the performance of liver tissue examinations by protocol or by clinical indication.113118 Autoimmune hepatitis recurs in 8% to 12% after 1 year and 36% to 68% after 5 years .113,119122De novo autoimmune hepatitis occurs in 1% to 7% of patients 1 month to 9 years after transplantation for nonautoimmune liver disease.108,120,123125
Diagnostic criteria for recurrent or de novo autoimmune hepatitis after liver transplantation have not been codified.113 Most patients have hypergammaglobulinemia, increased serum levels of IgG, conventional autoantibodies, and interface hepatitis with or without portal plasma cell infiltration.119,126,127 Adults with de novo autoimmune hepatitis may develop antibodies against glutathione-S-transferase T1 .128 Recurrent and de novo autoimmune hepatitis are variably responsive to conventional corticosteroid therapy cirrhosis develops in as many as 60% graft loss is possible and retransplantation is required in 8% to 50%.113

Autoimmune Hepatitis Causes And Risk Factors
Doctors aren’t sure exactly what causes your immune system to turn against your liver. Your genes may have something to do with it, since AIH can run in families.
But genes aren’t the whole story. Something you come into contact with may trigger your genes to set autoimmune hepatitis in motion. This could include:
- Medicines such as statins and hydralazine or antibiotics like nitrofurantoin and minocycline
- Infections such as viral hepatitis, herpes, Epstein-Barr, and measles
What Are The Treatments Of Autoimmune Hepatitis
The treatment plan usually differs from patient to patient. Every patient reacts differently to the line of treatment. Doctors do not recommend any treatment until there are any visible symptoms. Treatment starts if symptoms can be seen or the blood test reports are bad.
- In order to subside the inflammation of liver cells, the most common drug used is a corticosteroid named Prednisone. A higher dose of Prednisone is prescribed, and the dosage is lowered along the course of treatment. Another drug called Azathioprine or Purinethol, also a corticosteroid, would be added to the line of treatment after lowering the dose of Prednisone.
- The alternative treatment to Azathioprine is Cyclosporine and Tacrolimus. People may have side effects because they are under steroid medication, such as weak bones, high blood sugar levels, and increased urge to eat, leading to increased weight, eye problems, anxiety, and depression.
- After treatment of about three years, the majority of the patientâs symptoms and blood tests are under the normal range. Few doctors recommend immunosuppressants for life, or else recurrence rates are really high. Few others recommend that patients can stop medication after the symptoms have subsided and blood reports are normal, but the patient has been continuously being observed by their doctor, and their medication would start again once there is a relapse.

Is It Contagious Or Hereditary
It is absolutely not contagious. It is generally not considered an inherited disease but a tendency to autoimmune diseases may run in some families. That is, children of patients with autoimmune hepatitis may be at slightly increased risk of developing autoimmune diseases of the thyroid or liver or arthritis. The risk, however, is only slightly greater than the normal population and thus genetic counselling is not necessary.
Search For A Clinical Trial
Clinical trials are research studies that test how well new medical approaches work in people. Before an experimental treatment can be tested on human subjects in a clinical trial, it must have shown benefit in laboratory testing or animal research studies. The most promising treatments are then moved into clinical trials, with the goal of identifying new ways to safely and effectively prevent, screen for, diagnose, or treat a disease.
Speak with your doctor about the ongoing progress and results of these trials to get the most up-to-date information on new treatments. Participating in a clinical trial is a great way to contribute to curing, preventing and treating liver disease and its complications.
Start your search here to find clinical trials that need people like you.

What Is The Prognosis For Patients Who Have Autoimmune Hepatitis
If autoimmune hepatitis is diagnosed early, and treated with the proper medication, the liver may begin to heal and will be able to make healthy cells again to replace the inflamed and scarred cells. The patients symptoms will ease and the liver may begin to work normally.
The patient will need to be monitored and managed for the rest of his or her life, even if he or she is feeling better and liver function has improved. In many cases, the patient will need to be on medication for the rest of his or her life.

How Do Doctors Treat The Complications Of Autoimmune Hepatitis
If autoimmune hepatitis leads to cirrhosis, doctors can treat health problems and complications related to cirrhosis with medicines, surgery, and other medical procedures. If you have cirrhosis, you have a greater chance of developing liver cancer. Your doctor may order an ultrasound or other types of imaging tests to check for liver cancer.

Why Did I Get Autoimmune Hepatitis
Autoimmune hepatitis is rare. It can happen at any age, and affects more women than men.
We dont know why some people develop autoimmune hepatitis. Like other autoimmune conditions, its thought it might be triggered by an infection or certain medicines. It is likely that some people inherit an increased chance of getting autoimmune hepatitis.
