Developed By Patients, For Patients

The MPN Journal was created by John Hoogland, Dolf van den Berg, and Remco van Haaren — all MPN patients themselves. Their personal experience with the daily challenges of living with a Myeloproliferative Neoplasm (MPN) inspired them to develop this unique tool to support others on a similar journey.

Designed with ease of use in mind, the MPN Journal is a multilingual platform available in Danish, Dutch, English, Finnish, French, German, Italian, Norwegian, Portugese, Spanish and Swedish. It's fully web-based, meaning you can access it from any device — smartphone, tablet, or computer — without the need to download an app. Whether you're at home or on the go, your journal is always at your fingertips.

By using the MPN Journal, you not only gain valuable insights and control over your own health, but you also become part of a global community dedicated to improving MPN care and outcomes around the world.
