The Carenity community

Carenity is an online community that connects patients with chronic conditions (including rare diseases) and their loved ones.

The CDCN is currently working with Carenity to create and unite a European community around Castleman disease. Together, we are building the first patient-centered network in Europe which connects people affected by Castleman disease.

The aim of this community is to provide patients and their families with support in difficult times, a way to share their experiences and hopes, as well as access to articles and testimonials related to Castleman disease.

Join Carenity!

Carenity is available worldwide with dedicated platforms in France, USA, United-Kingdom, Spain, Italy and Germany.

Ambassador Program

For patients and loved ones diagnosed with Castleman disease, the diagnostic journey and the battle against this disease can be overwhelming and leave you feeling alone in this fight. This journey is complicated by the lack of knowledge that exists with this disease. As you continue your battle with Castleman disease, consider connecting with other patients or loved ones who have been through this and can offer support and guidance as you begin to navigate through this rare disease. We hope to help patients and loved ones obtain the most up to date information on Castleman disease, and access to all available resources and support.

The CDCN Patient Ambassador can assist patients in:

  • Answering questions about Castleman disease and diagnosis
  • Sharing information on treatment guidelines
  • Providing expert physician referrals
  • Connecting patients with other Castleman disease patients and loved ones
  • Offering support and guidance
  • Being available to talk to someone who has shared a similar experience
