Comparison of Gut Microbiota, Inflammation and Symptoms Following Allogeneic HSCT

This study will recruit 40 (20 with cGVHD and 20 without cGVHD) adults from the Bone Marrow Transplant Program at University of Florida Health Shands Cancer Hospital. After signing informed consent, participants will fill out questionnaires and have a blood sample collected from a vein in the arm. Participants will be given a stool collection kit with instruction and will return the sample via the mail. Data will be collected and securely stored in a system used by the cancer center for research. Descriptive statistics will be used to report individual, clinical factors, and symptoms. Knowledge gained from this study will provide preliminary data for future longitudinal studies to examine biological pathways for the development, severity and/or duration of cGVHD and symptom outcomes in individuals following allo-HSCT impacting quality of life.
