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

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/presentations

HHT Health Initiatives for the 21st Century

  • Prevalence in US:

- ? 1:5,000-10,000

- 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
preventable hht related healthcare costs estimated costs per incident

Preventable HHT-related Healthcare CostsEstimated costs per incident

(Data from 18 Years of Yale HHT Center Statistics)

  • Ischemic stroke $400,000
  • Brain abscess $500,000
  • Cerebral hemorrhage $500,000
  • Liver Transplant $315,000
  • Multiple Blood Transfusions $ 24,000 (annually)

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 worldwidewhile advocating for patient access to these Centers.

Advocate for and support those with HHTwhile increasing public, private, and governmental awareness of the disorder.

Engage the scientific and medical communityso 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

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.
