The European Paediatric Network for Haemophilia Management ( PedNet Registry)

Haemophilia is a rare condition where blood doesn’t clot properly, leading to bleeding problems. Because it's so uncommon, it's hard for one hospital alone to gather enough information to understand it fully. This is why the PedNet Registry was created – it’s a big study involving many hospitals across Europe. The main idea is to collect health information from lots of children with haemophilia A or B, all born between 2000 and 2040.

The study wants to learn several key things. For example, it looks at bleeding in newborn babies, and tries to understand why some children develop 'inhibitors.' Inhibitors are like antibodies that can make the usual haemophilia treatment less effective. The study also tracks the long-term health of these children, particularly how their joints are affected over time. By looking at a large group of children, researchers hope to find patterns and factors that influence these important aspects of haemophilia.

It's important to know that this is an 'observational' study. This means your child will not receive any new treatments or interventions specifically for this study. Instead, doctors will simply record information from your child's regular medical care, including details about their diagnosis, treatments, and any bleeding episodes. This information is usually collected anyway as part of their routine check-ups. The aim is to use this de-identified data to create better guidelines and improve care for all children with haemophilia in the future.
