Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research study is to create a clinical database and bio-repository. To do this, we will obtain blood, urine, saliva, and stool samples (e.g., biological samples) and personal health information from you to use in future research studies related to alcoholic hepatitis or other diseases. Part of your blood sample will be used to extract your DNA. DNA is the genetic material that gives us unique characteristics. We are doing this research study because we are trying to find out more about how and why illnesses related to alcoholic hepatitis or other diseases occur in people. To do this, we will study the biological samples and personal health information from healthy and sick people.

A "biological sample" is usually blood, but can be any body fluid. "Personal Health Information" includes such items as your name, age, gender, race, and/or your medical information. It can also include data from measurements and tests that you had while participating in another research study or that were done during the course of your regular medical care or doctor visits.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

What should I know about this research?

* Someone will explain this research to you.
* Taking part in this research is voluntary. Whether you take part is up to you.
* If you don't take part, it won't be held against you.
* You can take part now and later drop out, and it won't be held against you
* If you don't understand, ask questions.
* Ask all the questions you want before you decide.

How long will I be in this research? We expect that your taking part in this research will last up to 6 months, after the 6 months we will look in your medical records every 180 days for up to five years.

Why is this research being done? The purpose of this research is to create a clinical database and bio-repository to study alcoholic hepatitis.

What happens to me if I agree to take part in this research? If you decide to take part in this research study, the general procedures include: 1) allowing the investigators to review your medical records, 2) answering questions about you and your health, 3) completing questionnaires about alcohol use, 4) having a physical exam and blood drawn, and 5) providing urine and stool samples.

Could being in this research hurt me? The most important risks or discomforts that you may expect from taking part in this research include mild pain from blood draws and a small chance for a loss of confidentiality (e.g., unauthorized users gain access to sensitive and protected data about you).

Will being in this research benefit me? It is not expected that you will personally benefit from this research. Possible benefits to others may include understanding specific health conditions in patients with alcoholic hepatitis or other diseases.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. A clinical diagnosis of alcoholic hepatitis as defined by the NIAAA pan-consortia for AH:

1. Onset of jaundice (defined as serum total bilirubin \>3 mg/dL) within the prior 8 weeks to screening visit
2. Regular consumption of alcohol with an intake of \> 40 gm daily or \>280gm weekly on average for women and \> 60 gm daily or \>420gm weekly on average for men for 6 months or more, with less than 8 weeks of abstinence before onset of jaundice
3. AST \> 50 IU/l
4. AST:ALT \> 1.5 and both values \< 400 IU/l
5. and/or histological evidence of AH\*
2. Serum total bilirubin \>3 mg/dL
3. Subject or guardian ability to understand and willingness to provide written consent
4. Age greater or equal to 21 years
5. Re-enrolment of an alcoholic hepatitis donor is permissible up to 4 times if the donor presents with a new episode of alcoholic hepatitis 24 weeks or longer after the most recent enrolment in the study

1. History of chronic alcohol consumption sufficient to cause liver damage. Generally, this is considered to be \>40 g/day or \>280g/week on average for women and \>60 g/day or \>420 g/week on average for men, for 6 months or more. Judgement about chronic alcohol consumption will be made by the site investigator.
2. Subject or guardian ability to understand and willingness to provide written consent
3. Age greater or equal to 21 years

1. AUDIT-C scores of \<4 for men and \<3 for women (signifying no alcohol misuse)
2. Abstinent (consumption of less than one standard drink/week) during the 6 months prior to enrolment
3. Ability to understand and willingness to provide written consent.
4. Age greater or equal to 21 years

Exclusion Criteria

1. Liver disease significantly caused by hemochromatosis, autoimmune liver disease, Wilson disease, and acute viral hepatitis (NOTE: The presence of chronic hepatitis C, hepatitis B, HIV, or stage 1 (one lesion \<2 cm) HCC is not exclusion to participation)
2. Pregnant or breast feeding
3. Received liver transplant
4. Based on the judgment of the investigator, subject is not capable of understanding or complying with the study requirements

1. Past evidence of alcoholic liver disease, defined as a bilirubin \> 2.0 mg/dL, an AST \> 1.5 ULN, and any hospital admission for liver disease, or the presence of esophageal varices or ascites (at any time in the past)
2. Liver disease significantly caused by hemochromatosis, autoimmune liver disease, Wilson disease, NAFLD, and acute viral hepatitis (NOTE: The presence of chronic hepatitis C, hepatitis B, or HIV is not exclusion to participation.)
