|Brief Title ICMJE||Detection and Characterization of Host Defense Defects|
|Official Title ICMJE||Detection and Characterization of Host Defense Defects|
This study will: 1) determine the biochemical and genetic causes of inherited immune diseases affecting phagocytes (white blood cells that defend against bacterial and fungal infections); and 2) try to develop better ways to diagnose and treat patients with these diseases, and to prevent, diagnose and treat their infections.
Patients with chronic granulomatous disease (CGD), hyper immunoglobulin-E recurrent infection syndrome (HIE or Job s syndrome), chronic and cyclic neutropenia, Chediak-Higashi syndrome (CHS), leukocyte adhesion deficiency (LAD), and disseminated mycobacterial infections, and their family members, may be eligible for this study. Normal volunteers between the 18 and 70 years of age will also be enrolled.
All participants will donate 1 to 3 ounces (2 to 6 tablespoons) of blood at a time, but no more than 1 pint (32 tablespoons) for adults and one-half teaspoon per pound of body weight for children over a 6-week period. They will also have DNA studies to try to identify genetic factors related to inherited immune disorders. In addition,
This protocol is designed to evaluate selected patients with documented recurrent or unusual infections and their family members for clinical and in vitro correlates of immune abnormalities. It will also allow long term follow up of patients with host defense defects and permit us to periodically obtain blood, urine, saliva, skin, stool and vaginal specimens or wound drainage from such patients or their family members for medically indicated purposes and research studies related to understanding the genetic and biochemical bases of these diseases. This protocol may help provide patients and materials for the development of therapies for these diseases.

|Eligibility Criteria ICMJE||
Patients known to have or suspected of having an immune defect significantly or primarily involving the phagocytes will be eligible for enrollment, as well as their blood relatives. Such syndromes include but are not limited to those listed above. There will be no limit as age, sex, race or disability. Normal volunteers will be healthy adults between the age of 18 and 70 years and of either sex.
Subjects enrolled will be able to provide informed consent for themselves or if they lack the capacity to provide informed consent, the study team will comply with MAS 87-4.
The presence of an acquired abnormality which leads to immune defects, such as HIV, cytotoxic chemotherapy or malignancy could be grounds for possible exclusion if, in the opinion of the investigator, the presence of such disease process interfered with evaluation.
Subjects with dementia that impairs obtaining informed consent are excluded unless there is an appropriate surrogate (legal guardian or durable power of attorney who is willing to provide consent).
