Aging, Geriatric Syndromes and Clonal Hematopoiesis
April 23, 2024 updated by: Washington University School of Medicine
In this study the investigators will incorporate a wide range of clinical variables associated with aging and cardiovascular disease to determine whether they are associated with mutation status independent of chronologic age.
Clinically, aging can be operationalized using geriatric assessment, which entails a comprehensive multi-dimensional assessment of the health of an older adult, including measures of comorbidity, polypharmacy, functional status, cognition, depression, falls, social activities and social support.
Given that aging is heterogeneous, geriatric assessment allows greater specificity for aging than chronological age alone.

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.
Eligibility Criteria
Ages Eligible for Study
50 years and older (Adult, Older Adult)
Accepts Healthy Volunteers
Yes
Sampling Method
Non-Probability Sample
Study Population
Participants seen in Washington University School of Medicine clinics.
Description
Inclusion Criteria:
- At least 50 years of age.
- Able to understand written and spoken English.
- Able to understand and willing to sign an IRB-approved written informed consent document (or that of a legally authorized representative, if applicable for the trauma cohort)
Exclusion Criteria:
- Inability or unwillingness to complete health questionnaire.
- History of a recent (<30 days) acute viral illness.
- Current cancer diagnosis and currently receiving chemotherapy or undergoing radiation therapy. A prior history of cancer is allowed if the participant completed therapy > 1 year prior to enrollment; participants with a prior diagnosis of cancer will be asked to sign a release of information for the research team to obtain records regarding their prior cancer treatment.
- Current use of drugs that cause DNA damage (e.g. Cytoxan, azathioprine, etc.) for the treatment of a non-malignant disease.
- Vulnerable populations (e.g. prisoners).
- Known infection with Hepatitis B or C, HTLV, or HIV.
Additional exclusion for optional bone marrow aspirate/biopsy substudy:
- Use of medications for anticoagulation or "blood thinning" including warfarin, low molecular weight heparins (enoxaparin, daltaparin) or direct-acting oral anticoagulants (dabigatran, rivaroxaban, apixaban, edoxaban or betrixaban)
- allergy to lidocaine or other local anesthetics.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Background mutation rate in hematopoietic stem cells from older adults regardless of a prior cancer diagnosis as measured by the number and frequency of hematopoietic-specific mutations
Time Frame: Estimated to be 10 years
|
-The investigators will sequence the coding region of some or all of the genes in an individual's blood cells and compare results to their matched mouth cells to define hematopoietic-specific mutations.
The number of hematopoietic-specific mutations per individual and the frequency of individuals with mutations will be measured.
|
Estimated to be 10 years
|
Presence or absence of geriatric syndromes as measured by hematopoietic stem cell mutations
Time Frame: Estimated to be 10 years
|
-The presence or absence of geriatric syndromes will be correlated with the mutation status of individuals.
|
Estimated to be 10 years
|
Determine the natural history of mutations in older adults with clonal hematopoiesis as measured by risk to develop blood cancer/geriatric syndrome/illness/cardiovascular disease
Time Frame: Estimated to be 10 years
|
-Individuals with mutations will be followed longitudinally to monitor the fraction of hematopoietic cells with mutations, the functional consequences of mutations in their blood cells, and the risk of developing a blood cancer, geriatric syndrome, cardiovascular disease, or other illness.
|
Estimated to be 10 years
|
Presence or absence of cardiovascular disease as measured by hematopoietic stem call mutations
Time Frame: Estimated to be 10 years
|
Estimated to be 10 years
|
|
Determine whether expansion of clonal hematopoiesis (CH) occurs following acute trauma
Time Frame: Estimated to be 10 years
|
-Measures change in variant allele fraction
|
