The purpose of this study is to see if taking two nutritional supplements, zinc and SAMe (S-adenosylmethionine), can improve lung health and immune function in persons with HIV. You are being asked to volunteer because you have HIV (Human Immunodeficiency Virus) and you take anti-retroviral therapy (ART) medications.

There will be up to eleven study visits and three telephone visits. All study procedures are for research purposes. All study subjects will receive the nutritional supplements zinc and SAMe.

During the study you will be asked to answer questions about your alcohol use and smoking history. You will have exhaled breath tests, blood draws, physical exams, and bronchoscopies. Your medical records will be reviewed during the study. If you are a woman of childbearing age, a urine pregnancy test will be done at each study visit.

Treatment: The nutritional supplements zinc and SAMe will be given to you by the study team at visit 2. You will be asked to take the tablets once a day.

If you experience upset stomach, abdominal cramps, diarrhea, or other uncomfortable side effects, we will reduce the amount of the nutritional supplements. If you are unable to tolerate the nutritional supplements, you will be withdrawn from the research study.

Visits 3, 4, and 5 -Telephone Contact: You will receive a telephone call at one, two, and three weeks after visit 2 to ask you how you are tolerating the study supplements. If you are experiencing side effects such as upset stomach, abdominal cramps, or diarrhea, we will instruct you to decrease the dose of the supplements.

If your exhaled breath test is at goal at visit 6, you will continue to take the dietary supplements for one year from this point forward. If your exhaled breath test is not at goal at visit 6, you will be asked to return for visit 7. If your exhaled breath test is at goal at visit 7, you will continue to take the dietary supplements for one year from this point forward.
