Detection and Characterization of Host Defense Defects Clinical Trials References presented on Clinical Trials Search is not intended to be a substitute for proven healthcare advice, trips or professional assistance by using a real medical. We aren't mDs. Always confer with your physician about Detection and Characterization of Host Defense Defects conditions. Clinical Trials Search.org is a website devoted to listing clinical research studies in human subjects. Detection and Characterization of Host Defense Defects Clinical research trials and Detection and Characterization of Host Defense Defects medical trials take place in hundreds of localities across the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the effectualness of new does drugs. The purpose of the studies / projects is to solve specific human health questions. Clinical trials are a popular way for physicians, government agencies, and private sector companies to discover treatments for all sorts of conditions, such as Detection and Characterization of Host Defense Defects. Detection and Characterization of Host Defense Defects Clinical Trials and other clinical trials permit volunteers to access healthcare treatment choices before they are available to the general public. Some times the subjects recieve professional assistance for without cost, and every now and again they are compensated for their time. Sometimes there is a cost for a Detection and Characterization of Host Defense Defects clinical trial. Subjects often receive the most expert healthcare possible for their Detection and Characterization of Host Defense Defects condition. Risks are a reality, nevertheless, and could include additional or frequent dr. calls, healthcare dangers (perhaps life-jeopardising), and/or the treatment being ineffective. Trials are federally governed with stern guidelines to protect clinical trials subjects.

Detection and Characterization of Host Defense Defects
For Condition: Immunologic Deficiency Syndrome,Infection
Status: Recruiting
Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID) ,
Synopsis: 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, - Patients will have a personal and family medical history, physical examination and other procedures, which may include various blood tests; urinalysis; saliva collection; imaging studies such as chest X-ray, computed tomography (CT) or magnetic resonance imaging (MRI); and lung function studies, dental examination or eye examinations, if medically indicated. Patients who have draining wounds will have fluid collected from these wounds for biochemical study. Tissues removed as part of medical care, such as pieces of lung, liver, or teeth, or biopsies of these tissues will be studied. Patients who have an immune problem that investigators wish to study further will be asked to return to NIH for follow-up visits at irregular intervals, but at least every 6 months. The visits will include an updated medical history, examination directed at the particular medical problem related to the immune disorder, follow-up of abnormal tests or treatment, and collection of blood, saliva, urine, or wound fluid for study. Patients with a severe bacterial infection may receive treatment with a drug called meropenem, given at a maximum dose of up to 2 grams every 8 hours. - Family members will have a medical history, saliva or urine collection, and chest X-ray or other imaging study, if medically indicated. - Normal volunteers who have had tissue biopsies or pieces of tissue removed as part of medical care, such as pieces of lung, liver, or teeth, will have these tissues studied.
Details: 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, 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:
Study Type: Observational, Natural History
Minimum Age/Maximum Age: /
Genders: Both
Protocol Entry Criteria: INCLUSION CRITERIA: 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 chronic granulomatous disease (CGD), Hyper immunoglobulin-E recurrent infection syndrome (HIE or Job's syndrome), chronic and cyclic neutropenia, Chediak-Higashi syndrome (CHS), leucocyte adhesion deficiency (LAD), and disseminated mycobacterial infections. There will be no limit as to age, sex, race or disability. Normal volunteers will be healthy adults between the age of 18 and 70 years and of either sex. EXCLUSION CRITERIA: 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 interferes with evaluation.
