RECRUITING

Immune Cell Response to Stimuli

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This study will investigate the response of immune cells (neutrophils, monocytes) to various signals in the test tube to determine how they sense the signals in the body and what substances they produce in response to them. It will determine how the cells may, under certain circumstances, contribute to inflammation, and will measure substances in the blood plasma (the liquid, non-cellular part of the blood) that might stimulate white blood cells, in order to understand how the blood responds to possible disease-related conditions. Healthy normal volunteers 18 years of age and older who weigh at least 110 pounds may be eligible for this study. Participants give about 320 milliliters (mL) of blood (about 1 1/3 cups) or less at each donation. They donate no more than once every 8 weeks and no more than six times a year. On some occasions, less than 320 mL of blood may be drawn. The collected blood is separated into its components and specific cells are exposed to substances to examine their response.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:18 Years to 65 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:Yes
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * Normal, healthy adult donors as judged by screening questionnaire
  2. * Nonpregnant
  3. * Weighing at least 110 lbs
  4. * 18-65 years of age
  5. * HIV negative (proof required every 6 months we will conduct test)\*
  6. * Hepatitis B surface antigen and hepatitis C serology negative (checked every 6 months we will conduct test)\*
  7. * The rationale for HIV and hepatitis viral testing is that chronic viral infection may alter and possibly invalidate our experimental results. HIV and hepatitis results will be confidentially obtained. Testing will be contracted to an external certified laboratory and will be paid for by the study group. Results will be available only to the study doctor/PI (Fessler), the study coordinator, the CRU Director (Garantziotis, LAI), and the donor, with the few caveats that follow
  1. * Hematocrit less than 34% for women or less than 36% for men, or greater than 56% for either gender.
  2. * Patients will be informed of disqualifying vital signs and hematocrit values and advised by trained staff, as appropriate, to seek assistance from their physician.
