Many bacteria live in the gut. The gut is the tube that moves food from the mouth through the stomach to the intestines. Heavy alcohol use disturbs these bacteria. There is evidence that the bacteria in the gut may affect anxiety and depression. Researchers want to learn more about these bacteria in order to better treat diseases such as alcohol dependence.
Objective:
To identify the different bacteria that live in the mouth and gut. Also, to learn if these bacteria change as a person goes through alcohol detoxification.
Eligibility:
People ages 18 and older who:
-Enrolled in screening protocol 14-AA-0181
-Are going through detoxification treatment at the Clinical Center
Design:
Participants will have physical exams.
Participants will answer questions about:
-Anxiety and depression
-Alcohol use
-Sleep
-Abdominal and oral health
-Diet
Participants will keep a regular record of their diet.
Participants will have breath alcohol analysis 4 times per day.
Participants will provide stool and oral specimens at most once a day for the first week. Then, they will provide them once a week while they are at the Clinical Center.
-For the oral specimen: A small brush rubs the tongue. They may not eat, drink, or perform oral care within 2 hours of collection.
-For the stool specimen: They will receive a container that fits in the toilet. They will let the nurse know right away when the sample is ready.
Participants will have a dental visit. This consists of an oral exam and oral health assessment. The dentist may recommend a cleaning or dental X-rays.
