What is Genomic Medicine?
• DNA & RNA Testing: – Personalized Medicine
• An Accepted Standard of Care• Applications
– Sensitivity to Adverse Drug Reactions– Inherited Diseases & Syndromes– Cancer Diagnosis– Infectious Disease
Clinical & Research Genomics Core
The Concept
The same technologies used for clinically required DNA testing in the clinical laboratory are made available to support research in a single core laboratory facility.
• Clinical Laboratory directly meeting requirements of Veterans Healthcare
• CLIA Certified Laboratory for Research• Collaborative• Translational
Clinical & Research Genomics Core
Organization
• Start-up Grant from Office of Research and Development
• Clinical testing supported by clinical funds• Research supported by grant funds
Clinical & Research Genomics Core
Support
• FISH: Fluorescent in situ Hybridization• PCR, DNA Sequencing• Genotyping by Microarray Hybridization
Clinical & Research Genomics Core
Technologies
Current Testing CapabilitiesUrovysion:
A sensitive method for diagnosis of bladder cancer and early detection of recurrences.
Current Testing Capabilities
• Predicting Optimum Drug Dosage– Cytochrome P450’s:
• CYP 2C9, 2D6, 2C19, 3A4, 3A5
– Others:• VKORC1, UGT1A1
“Here’s my sequence . . .”
Current Testing Capabilities
• Prediction of Tumor Response to Therapy– K-ras Mutation Detection– Microsatellite Instability
• Diagnosis of leukemia and lymphoma– Gene Rearrangement Assays
• Risk factors for coagulation disorders– Factor V Leiden– Prothrombin G20210A
The Research Core
• Collaborative efforts to support a wide variety of research projects.
• Examples:– Evaluating Clinical Utility of Genetic Testing in
Warfarin Dosing– Pharmacogenomic assay validation– Neurotransmitter expression in PTSD model– Testing genomic markers of risk for mental health
disorders
• Too Little Thrombosis• Too Much Bleeding• Complications cause 43,000
ED visits/year in USA.• Wide variation in dose
requirements
Example: Warfarin Dosing
Warfarin Dosing: Clinical & Research Challenges
• Implement genetic testing data into Warfarin dosing decisions.
Clinical:
• Does genetic testing reduce the incidence of adverse reactions?
• Are there genetic markers of adverse reactions specific for minority populations?
Research:
Warfarin: Collaborations
• Clinical Staff• Pharmacy• ACOS Research• ACOS Informatics• Anticoagulation Research Lab
Warfarin: Accomplishments• Assay Development
– 3 well established markers
– 11 markers seen in minority groups
• Educational Activities• Software evaluations
– Incorporating genetic data into dosing– Interface with Electronic Medical Record
• Research Collaboration
Benefits to Veterans
• Tests already in use to support cancer diagnostics, clotting risk, Warfarin sensitivity.
• Reduced costs for clinical tests• Fewer days in the hospital• Fewer serious adverse drug reactions• More effective cancer treatments• Disease Prevention: Knowing the risk

HIV Research: Improving Veterans’ Lives
• A Veteran Participating in HIV Research– 42-year old man who presents to the AEC with swollen
lymph nodes, fever and fatigue and is offered HIV testing– After receiving positive test results in Yellow Team he is
escorted to ID Clinic and provided crisis management and further medical assessment
– His primary care is transferred to ID and during a regular visit, he is invited to participate in a randomized treatment trial for antiretroviral naïve volunteers
– He declines, but he is introduced to research team members and the informed consent process, and learns how research is integrated in and complementary to HIV primary care
HIV Research: Improving Veterans’ Lives
– Patient declines participation in the randomized trial but accepts an invitation to attend a meeting of the ID Clinic research advisory board
– Patient’s interest in clinical trials increases as he learns more about treatment regimens, protocol development, informed consent, volunteer recruitment and retention strategies, and opportunities for veterans to collaborate with scientists in the VA protocol development process
– When an observational, non-interventional trial becomes available at the site, he joins the study
– Over time, patient’s interest in HIV science propels him to become a leader of the ID Clinic research advisory board and a prominent HIV treatment activist in multiple networks in DC and the nation
Veterans Living with HIV
• Largest single provider of direct HIV care in the United States
• Approximately 23,000 true unique patients with HIV infection

Type of HIV Research
• Research is an integral part of the VA’s efforts to improve the diagnosis, treatment and prevention of HIV infection
• HIV Treatment Research• Optimizing clinical management of
HIV/AIDS, including co-infections and other HIV-related conditions
Major Collaborations• VA Cooperative Studies• Centers for Disease Control
– Tuberculosis Trials Consortium• National Institutes of Health
– Community Programs for Clinical Research on AIDS (CPCRA)
– International Network for Strategic Initiatives in Global HIV Trials (INSIGHT)
– HIV Prevention Trials Network (HPTN)– AIDS Clinical Trials Group (ACTG)

NIH Warns AIDS Patients Against Stopping Therapy
Study Finds People Who Forgo Continuous Treatment More Likely to Develop Other Illnesses or Die
A13
By
DAVID BROWN
Washington Post Staff Writer
People infected with the AIDS virus who periodically interrupt their drug treatment run a higher risk of falling ill and dying of both AIDS and other diseases compared with people who stay on the
medicines.
That is the conclusion of the largest and most expensive AIDS treatment study ever conducted….
Selected Publications on Non‐AIDS Events
How HIV Research Improves Veterans’ Lives
• Death Sentence Survival• Despair Hope/Optimism• Quantity and Quality of life• Thriving
– Achieving sobriety– Acquiring housing– Pursuing higher education/training/career advancement– Maintaining stronger Relationships– Addressing other health issues (smoking, obesity, etc)– Pursuing dreams, aspirations and a future
How HIV Research Improves Veterans’ Lives
• Altruism• Mental Health - "a state of well-being in which the
individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to his or her community”
• High Acceptance of Research Participation/Repeat Volunteers
• Enhances primary care• Advocacy
How HIV Research Shapes Healthcare Delivery
• Expanded treatment options• Increasing complexity• Outpatient management• Shorter hospitalizations • Development of a chronic disease
management paradigm for lifelong care of HIV infection
Impact on International Scope and Next Steps
• Emphasis on earlier intervention• Improve early detection of HIV infection• Expand and simplify HIV testing• Prevention education programs associated
with relevant VA programs: drug treatment programs, homeless programs, counseling programs, domiciliary facilities, STD programs and primary care clinics
HIV Research: Improving Veterans’ Lives
Many, many thanks to our nation’s veterans for
volunteering to participate in HIV research studies

Questions• Does fitness reduce mortality risk
(improve survival) in veterans with DM? • Is fitness effective if DM co-exists with
other risk factors? • Is it effective in both young and older
diabetics?• Are the health benefits similar for African-
Americans and Caucasians?

Question 4
Does fitness have similar beneficial effects for African-Americans
and Caucasians?
An intriguing finding of some studies is that African-American diabetics exhibit
significantly lower exercise capacity than do Caucasian diabetics.

Summary of Our Findings
• Increased fitness is associated with reduced risk of mortality for all diabetics regardless of age, risk factors or race.
• Mortality rates were lower by at least 40% and up to 70% in some cases, for Moderate and High-Fit diabetic veterans
• The risk was reduced by 17% for every one unit increase in the level of fitness.
