Vascular EDS Research

Our Vision
Annabelle’s Challenge is committed to driving person-centred research that transforms the landscape of vascular Ehlers–Danlos Syndrome (vEDS) management. 

Our vision is a future in which the whole vEDS community—people with vEDS, their families, friends, and wider support networks—has a strong voice in research and access to the highest standards of care.

Our Guiding Principle: “Nothing About Us Without Us”
We recognise that individuals and families living with vEDS are the primary experts in their own condition. Our work is grounded in the principle of “Nothing About Us Without Us” (NAWWU): patients, caregivers, family members, clinicians, and researchers collaborate as equal partners in shaping research priorities, interpreting findings, and implementing change. 

This co-production ensures that the issues that matter most to the vEDS community—daily functioning, quality of life, emergency care, pregnancy management, and developing future treatments—remain at the forefront of the research we support. 

With over 600 genetically confirmed patients registered on our database we are uniquely placed to facilitate research and clinical trials.

Our Commitment to Action
• Fund Patient-Centred Research
We invest in high-quality, ethically approved studies that align with the research priorities defined by our community.

• Facilitate Data Sharing and Collaboration
We help build and sustain international vEDS registries, biobanks, and research initiatives—essential foundations for rare disease progress.

• Empower Patients and Families
We provide resources and education to strengthen self-advocacy and ensure meaningful participation in research and care.

• Collaborate Globally
We work with partner charities, academic institutions, clinical teams, and services such as the UK National Diagnostic Service for EDS to foster a unified and effective research landscape.

Our Research Priorities

1. Improving Diagnosis & Management

vEDS is often diagnosed only after a major vascular event. We champion research that enables early, accurate, and non-invasive diagnosis, including studies that guide clinical management and improved long-term care.


2. Understanding the Lived Experience & Quality of Life

We prioritise research that captures the realities of living with vEDS, including daily challenges, psychological impacts, and broader quality-of-life outcomes. We support studies aimed at identifying modifiable factors and developing interventions that enhance wellbeing


3. Optimising Care Pathways & Emergency Preparedness

We support research that helps develop evidence-based, multidisciplinary care pathways, emergency protocols, and surgical decision-making models tailored to the unique tissue fragility associated with vEDS.


4. Developing Novel Therapeutics

We support the development of innovative treatments—from established pharmacological options to emerging regenerative and gene therapies that target the biological root of vEDS.


What we've achieved so far

  • Funded vEDS research projects and programmes. 
  • Funded our first ever scientific research to create a vEDS zebra fish model.
  • Established a PPIE group through our existing steering committee.
  • Facilitated and recruited patients for 17 research projects.
  • Hosted the world's first ever conference for vascular EDS patients and clinicians.
  • Supported 2 x vEDS Clinical Trials.
  • Supported MSc student Genetic Counsellors through Cardiff University. 
  • Collaborated with The EDS Society, EDS Support UK and The Marfan Foundation (VEDS Movement).
  • Implemented our research priorities and governance strategy.
  • Co-funded the creation of one of the largest rarer type EDS research databases in the world with EDS UK and the creation of The NEEDS Study.

Planning Research?

As a community, we believe research should reflect the priorities and lived experiences of people with vEDS and their families.


For all projects where we may be involved—whether through recruitment, co-design, advisory input, or evaluation—we prefer to be engaged from the earliest design phase. Early involvement allows us to work collaboratively with researchers to shape study design, ensure relevance and feasibility and make participation as safe, respectful and meaningful as possible.


If you are planning research involving the vEDS community, please reach out at the earliest stage. We want to collaborate and help make your study the best it can be.


Vascular EDS can take life in an instant. Help us change that.

Annabelle's Challenge & EDS Service Collaboration

A unique collaborative model providing supportive and self-advocacy tools to the rare disease community.


Juliette M. Harris, Jacqui Fish, Jared Griffin, Gemma Hasnaoui, Clare Stacey, Neeti Ghali, Fleur S. van Dijk.


This is a great example of collaborative work of the EDS Service, a highly specialised service commissioned by NHS England and Annabelle's Challenge Vascular EDS Charity including health care professionals, patients, carers and members of the emergency care project team.


The recommendations from this unique collaborative model include eight specific domains of self-advocacy: increasing knowledge of rare disease, taking care of mental well-being, taking care of physical well-being including routine care, the development of good working relationships between patients and health care professionals, information accessibility, emergency preparedness, taking part in education and outreach, and involvement in research and feedback opportunities.


Highlights

  • Having a rare disease presents a unique set of health care challenges.
  • Self-advocacy can help people with a rare disease get their needs met.
  • Empowering health care professionals in rare disease is important.
  • Specialised services are uniquely placed to help people with rare diseases.
  • Collaborations between patients and health care professionals support self-advocacy.

Steering Committee & PPIE Group

Working directly for the charity and the community we serve. 


The steering committee and PPIE group help to shape the future of the charity as it continues to grow providing support, guidance and oversight of progress of all vEDS community based projects including research. The team is made up of volunteers who are directly touched by vascular EDS including patients, parents and carers, they are also supported by genetic counsellors from the NHS EDS National Diagnostic Service.


Our Research Lead is Claire Green, Genetic Counsellor, Sheffield EDS Service.

NEEDS Study

Research funded by Annabelle’s Challenge and EDS UK in 2019 has led to a new 10 year study of rare types of Ehlers-Danlos syndromes (EDS). 

The Natural history Exploration of rare EDS types (the NEEDS study) is led by Dr Fleur van Dijk in collaboration with Dr Neeti Ghali from the National EDS Diagnostic Service at London North West University Healthcare NHS Trust and with other consultants from Great Ormond Street Hospital and St Bartholomew’s Hospital.

The NEEDS study aims to increase knowledge about the clinical and genetic features of children and adults with rare types of EDS by having, amongst other things, a research database. This has the potential to improve the management of the different rare EDS types, to enable the discovery of more genetic causes which might be associated with them and to develop potential for new and improved therapies.
