Brief Summary
The purpose of this study is to examine the gut bacteria, levels of peripheral blood inflammation markers, and symptoms in patients with and without chronic graft-versus-host disease (cGVHD) following allogeneic hematopoietic stem cell transplant (allo-HSCT). The hypothesis is that individuals with cGVHD will have lower levels of microbial diversity, higher levels of inflammatory metabolites in stool and peripheral measures, and higher levels of symptoms than individuals without cGVHD.

Outcome Measures
Primary Outcomes (3)
Plasma levels of inflammatory markers (cytokines and CRP) of individuals post allogeneic HSCT
Cytokines will be analyzed using a multiplex assay by Millipore Company. Compared to the traditional enzyme-linked immunosorbant assays (ELISA), the multiplex is comparable and more sensitive to lower concentration levels of cytokines than the ELISA. One laser identifies a specific bead and another laser identifies the reported antibody associated with the bead-bound cytokine. One hundred beads for each of the 17 cytokines in every sample are assayed and a mean cytokine binding for the sample is determined. The manufacturer reports that the assay accurately measures cytokine values in a range of 1-2500pg/ml. Serum CRP will be measured using the ALPCO's (American Laboratory Products Company) high-sensitivity CRP assay which uses latex particle enhanced immunoturbidimetry for quantitative CRP determination.
Day 1
Diversity and levels of fecal microbes of individuals post allogeneic HSCT
Fecal microbial DNA will be extracted from between 50-200 mg of fecal material. The 16S ribosomal gene (V4 region) of each sample will be amplified using a barcoding system to allow multiplexing with the Illumina MiSeq system. We will use UNIFRAC algorithm to evaluate the null hypothesis that the structure of the microbial community is insensitive to cGVHD and symptoms of cGVHD. Differences in taxa are implicated by our high throughput sequencing methods will be confirmed by other techniques including culturing (where appropriate) and qPCR with taxa-specific primers.

Eligibility Criteria
20 allo-Hematopoietic Stem Cell Transplantation (HSCT) recipients with chronic graft-versus-host disease (cGVHD) and 20 allo-Hematopoietic Stem Cell Transplantation (HSCT) recipients without chronic graft-versus-host disease (cGVHD)
You may qualify if:
- Group 1: Adults (\> 18 years of age) within 3 months to 3 years of receiving allogeneic hematopoietic stem cell transplant (allo-HSCT) diagnosed with cGVHD;
- Group 2: Adults (\> 18 years of age) within 3 months to 3 years of receiving allo-HSCT without a diagnosis of cGVHD; and
- All participants must be able and willing to complete paper and pencil questionnaires, provide a blood and stool sample, and be able to give informed consent.
You may not qualify if:
- Diagnosed with a significant secondary inflammatory disease such as multiple sclerosis, Crohn's disease, rheumatoid arthritis or secondary cancer;
- History of a major psychological disorder requiring psychotropic medications or initiation of antidepressants within 30 days of enrollment;
- Incarcerated or pregnant; or
- Any other condition that in the opinion of the principal investigator (PI) may compromise study participation will not be eligible for participation in this study.
