Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: The way the body heals and protects itself from getting sick is called the immune response. Some people with weak immune systems get sick often or get rashes and skin infections. Researchers want to find out how the immune system and skin problems are related so they can help these people. Objective: To learn about how immune response and skin healing are related to each other. Eligibility: People ages 18-65 with hyper IgE syndrome or Job syndrome or people ages 7-65 with chronic granulomatous disease. Healthy volunteers ages 18 65 are also needed. Design: Participants will be screened with: Medical history Physical exam Possible urine tests Participants will have 1 to 3 visits within about a week. Visits will include the following: Participants will have a wells device strapped to the inside of the forearm. It will suction the skin and pull the top layer away to form 8 blisters. The skin over the blisters and the liquid inside will be collected. Participants will have up to 4 skin biopsies. A sharp tool will remove a small plug of skin from the forearm. Participants may have blood and urine tests. The skin on participants skin will be rubbed with a cotton swab. Some participants will have an overnight visit. They will have the blister device placed back on the arm. The wells will be lined up over the blister wounds. The wells will be filled with either saline or the participant s blood serum. The device will be covered and left on the arm for up to 24 hours. Doctors will periodically remove some liquid from the wells.
