HHT Health Initiatives for the 21st
Century Purpose of the Conference
  • Bring together individuals from a broad range of
    disciplines to work to
  • 1. increase awareness of HHT in the United
    States
  • 2. develop a plan to
  • - improve early recognition and intervention
  • - improve clinical outcomes of persons with
    HHT
  • Ultimate goals
  • reduce health and economic impact of HHT
  • enhance quality of life of persons with HHT

What is Hereditary Hemorrhagic Telangiectasia?
HHT Health Initiatives for the 21st Century
  • Complex genetic (autosomal dominant) blood vessel
    disorder
  • Defect in development of some blood vessels
    (capillaries), forming
  • telangiectases
  • arteriovenous malformations or fistulas (AVM /
    AVF)
  • other vascular lesions
  • Wide range of clinical manifestations/presentation
    s

5
Why spend time, energy and resources on HHT?
HHT Health Initiatives for the 21st Century
  • Prevalence in US
  • - ? 15,000-10,000
  • - Up to 75,000 Americans may have HHT
  • Variable clinical presentation and health care
    provider awareness makes diagnosis of HHT
    challenging
  • Most serious complications (including death in
    10-20 of persons with HHT) can be prevented by
    screening and treatment using successful
    approaches and techniques

HHT Foundation International
Mission to find a cure for HHT while saving the
lives and improving the well-being of individuals
and families affected by HHT. To achieve this
mission, the HHT Foundation will Fund research
to find better treatments and a cure. Educate
families and physicians about HHT so that
awareness of crucial diagnosis and available
treatments prevents needless disability and
death. Provide linkages between people affected
by HHT. Collaborate with multidisciplinary HHT
Treatment Centers worldwide while advocating for
patient access to these Centers. Advocate for
and support those with HHT while increasing
public, private, and governmental awareness of
the disorder. Engage the scientific and medical
community so that talented individuals dedicate
efforts toward advances in HHT screening,
diagnosis, treatment, and research.

HHT Language Reported by House and Senate
Appropriations Committee- FY 2008
  • H.R. 3043, The Labor, HHS., Education and Related
    Agencies Appropriation Bill
  • Encourages the CDC to establish an HHT resource
    center to increase identification of people with
    HHT, and increase knowledge, education and
    outreach of this largely preventable
    life-threatening condition. The Committee
    encourages CDC to provide information on
    effective evidence-based interventions and
    treatments to prevent premature death in the HHT
    population, improve outcomes and the quality of
    life for people living with HHT by creating a
    database to collect and analyze data, support
    epidemiology studies, provide surveillance, and
    train health care professionals.
  • S. 1710, The Labor, HHS., Education and Related
    Agencies Appropriation Bill
  • The Committee is aware of interest in the
    establishment of a Hereditary Hemorrhagic
    Telangiectasia National Resource Center. The
    Committee encourages the CDC to examine carefully
    proposals to establish such a center.

Despite efforts to date, many persons with HHT
remain undiagnosed and experience significant
morbidity and mortality
