Conditions
Summary
Background: \- The immune system is made up of special cells, tissues, and organs that fight infections. Problems with this system may lead to frequent, severe, or unusual fungal infections. These infections are often difficult to treat. Researchers want to collect blood and tissue samples from people who have unusual, persistent or severe fungal infections or immune problems that increase the risk of these infections. Objectives: \- To collect medical information and samples for a long-term study of people with immune system problems that lead to fungal infections. Eligibility: * People with a history of fungal infections caused by immune system problems. * Parents, children, and siblings of this group. * Healthy volunteers not related to the first two groups. Design: * This long-term study may last for up to 25 years. Those in the study may need to provide new information about every 6 months. The procedures for each person may vary with the particular diagnosis and the extent of fungal infection. Healthy volunteers may have only one or two visits. * At the first visit, those in the study will have a full medical history and physical exam. They will also provide blood. * Research procedures may include the following: * Saliva, urine or stool testing * Mouthwash collection for DNA testing * Collection of cheek cells, nail clippings, or vaginal fluid * Tests of leftover tissue or body fluid from previous medical procedures * Skin or oral mucous membrane biopsy * Collection of white blood cells * Followup visits will involve a physical exam and updated medical history. Blood, saliva, urine, or nail clipping samples may be taken for ongoing studies. Any additional tests or exams required by the study doctors may also be done. * Participants may withdraw from the study pool at any time.

Exclusion Criteria16
- Patients:
- A patient will not be eligible if he/she has any of the following:
- Any condition which, in the investigator's opinion, may interfere with the evaluation of a co-existing abnormality of immunity that is the subject of study under this protocol.
- Any condition which, in the investigator's opinion, places the patient at undue risk by participating in the study.
- Unwillingness to undergo testing or procedures associated with this protocol.
- Patient Relatives:
- A genetically related relative will not be eligible for this study if he/she has any condition which, in the investigator's opinion, may interfere with the evaluation of an immune system abnormality that is the subject of study under this protocol.
- Healthy Volunteers:
- A healthy volunteer will not be eligible if he/she has any of the following:
- HIV infection.
- History of recurrent or severe infections.
- History of an underlying malignancy or receipt of cancer chemotherapy within the past 5 years
- Receipt of systemic corticosteroids or other systemic immunosuppressants or immunomodulators within the past 30 days
- Pregnancy or lactating
- History of heart, lung, kidney disease, or bleeding disorders.
- Any condition which, in the investigator's opinion, may interfere with the comparison of clinical specimens against those obtained from affected subjects.
