ESID EHA SIOPE Focused Symposium 2025
``The Interplay of Immunology & Haematology``

800 clinical experts, researchers, early careers, and other HCPs came together in Vienna to elevate the care and outcomes of their immunodeficiency, haematology and cancer patients. They tackled questions such as:

When should we screen our primary immunodeficiency, haematology or oncology patients for underlying or additional risks?

How best should we treat oncology/haematology patients with an underlying primary ID or secondary ID?

How can we better coordinate with colleagues in other fields to improve care?

Thank you to everyone who engaged on the interplay at the ESID EHA SIOPE Focused Symposium in Vienna, on 18-20 November 2025.

3 Societies, 1 Mission

The intersection between immunodeficiencies, haematologic conditions, and oncology has become ever more apparent. As we witness increasing complexity in patient diagnoses and treatments, the need for a collaborative, multidisciplinary approach is more critical than ever, as each of our specialties offers unique insights that contribute to improving diagnosis, treatment, and management strategies.

By putting our patient in the centre and working across disciplines we can build a future where they receive the optimal healthcare.

Explore the pathophysiological and clinical interplay between these fields.

Hear the latest ideas and expand multidisciplinary research.

Discuss and collaborate on new methods for improving patient care.
