IPOPI HARD TALKS

A dialogue between Prof Silvia Sánchez-Ramón and Dr Selket Delafontaine

Are SIDs Undiagnosed PIDs?

Join us for the upcoming Hard Talks session to discuss whether secondary immunodeficiencies (SIDs) may actually be undiagnosed primary immunodeficiencies (PIDs).

In this webinar, Dr Selket Delafontaine will explore the clinical overlap between secondary immunodeficiencies (SIDs) and primary immunodeficiencies (PIDs), also known as inborn errors of immunity (IEIs). Drawing on current data and clinical cases, she will highlight the challenges of recognising an underlying PID/IEI in patients whose immunodeficiency may initially appear to be secondary to cancer. Prof Silvia Sánchez-Ramón will enrich the discussion by focusing on the subtle but important clues that can help uncover an underlying PID/IEI in patients with haematological malignancies.

The IPOPI Hard Talks series is designed for clinicians, nurses, and patient group leaders interested in PID diagnosis and clinical management. Featuring interactive discussions and a lively debate between expert speakers, “PID Hard Talks” aims to address the more challenging topics and increase expertise on crucial clinical care issues.

The session will be moderated by Martine Pergent (IPOPI President) and Dr Nizar Mahlaoui (Chair of IPOPI MAP).
