Candidates will be screened with a medical history, physical examination, blood and urine tests and possibly an electrocardiogram (EKG). Blood tests may include HLA typing, a genetic test of immune system markers.\n\nParticipants may undergo the following procedures:\n\n* Blood tests (patients and volunteers)\n* Biopsies The frequency of biopsies for given patients may vary, depending on their specific therapy. Typically, biopsies are done at a single time, or for patients starting a new therapy, biopsies could be performed before starting therapy, during therapy and possibly after completion of therapy.\n* Tonsil biopsies (patients and volunteers) Volunteers will have one tonsil biopsy. Patients will have no more than six tonsil biopsies, with no more than three in a 10-day period. The biopsy is done by an ear, nose and throat specialist as an outpatient procedure. The tonsils are numbed with a local anesthetic, and one to four pieces of tissue are extracted.\n* Lymph node biopsies (patients only) Patients will have no more than four lymph node biopsies, performed no more frequently than once a month. The biopsy is done by a surgeon and may require a 2- to 3-day hospital stay. The skin above the lymph nodes is numbed with a local anesthetic, an incision is made and the tissue is removed. Alternatively, a needle biopsy may be done, in which a small amount of lymph tissue is withdrawn through a special needle injected into the site.\n* Intestinal biopsies (patients and volunteers) Volunteers will have one intestinal biopsy procedure. Patients may have up to six intestinal biopsy procedures, each separated by at least 10 days. This is done by a gastroenterologist as an outpatient procedure. A flexible tube (sigmoidoscope or colonoscope) with a light and special lens at the tip is inserted into the rectum and large bowel. Wire instruments passed through the tube are used to extract small tissue samples.\n* Bronchoalveolar lavage (BAL; patients and volunteers) Volunteers and patients will undergo bronchoscopy in which a flexible tube (bronchoscope) with a light and special lens at the tip is inserted through the nose or mouth into the lungs, and the lining of the lung is sampled by washing the airways with small amounts of saline. The procedure is performed by a pulmonologist or critical care specialist, usually as an outpatient.", "detailedDescription"=>"Examining tissues outside the bloodstream in HIV-infected patients, patients with Idiopathic CD4 lymphopenia (ICL) and, for comparison, HIV-uninfected healthy volunteers (hereafter referred to as healthy volunteers), can provide insights into the pathogenesis of HIV infection and ICL. This protocol will provide a mechanism for sampling tissue sites. A total of 430 HIV-infected patients, 100 ICL patients and 105 healthy volunteers will be enrolled in these studies. To assess changes in viral load and immunological parameters at sites outside the bloodstream during therapy of HIV-infected patients, sequential tonsillar, lymph node, or intestinal biopsies, or bronchoscopy with bronchoalveolar lavage (BAL) will be undertaken during the course of therapy. In a small number of patients, sequential or simultaneous lymph node biopsies will be performed. In addition, uninfected healthy volunteers will be enrolled to have a tonsillar or intestinal biopsy, or bronchoscopy with BAL; this will allow comparison of immunologic parameters in HIVinfected and uninfected tonsillar or intestinal tissues, or BAL fluid. Finally, ICL patients may have tissue sampling to assess lymphocyte distribution and possible function in tissues to better understand the pathogenesis of their lymphopenia. Sequential or simultaneous tissue sampling may occur and longitudinal samples may also be obtained to assess stability in tissue compartments or effect of possible immunomodulatory treatments."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "maximumAge"=>"100 years", "minimumAge"=>"18 years", "samplingMethod"=>"NON_PROBABILITY_SAMPLE", "studyPopulation"=>"This study will include patients already seen in our outpatient clinic, as well as individuals recruited from outside clinics.", "healthyVolunteers"=>true, "eligibilityCriteria"=>"* INCLUSION CRITERIA:\n\nGreater than or equal to 18 years old.\n\nAbility to sign informed consent.\n\nFor women of child-bearing potential, negative result on a serum or urine pregnancy test within 1 week prior to the procedure.\n\nWillingness to allow storage of blood or biopsy samples for possible future use to study HIV/AIDS, related diseases or the immune system; willingness to permit HLA testing.\n\nFOR PATIENTS UNDERGOING BIOPSIES:\n\nNo medical contraindication to tonsillar, lymph node, or intestinal biopsy.\n\nFor tonsillar biopsy, presence of visible tonsillar tissue; for lymph node biopsy, palpable lymph nodes.\n\nNo aspirin or piroxicam (Feldene) for 10 days prior to the procedure; other non steroidal anti-inflammatory drugs (e.g. ibuprofen) must be discontinued the day prior to the procedure.
