What we do
About our project
Background information
Pompe disease is the first inherited muscle disease for which a disease-specific treatment has been developed: the deficient enzyme can be intravenously supplied through enzyme-replacement therapy (ERT) with alglucosidase alfa.
Overall aim
Our aim is to investigate the long-term effects of enzyme-replacement therapy in children and adults with Pompe disease, and to define predictive factors for a favorable outcome.
Research method
All patients known with Pompe disease at our Center are followed through a standardized follow-up protocol.
We focus on the long-term effects of enzyme-replacement therapy on: muscle strength, muscle function, pulmonary function, cardiac function, hearing, speech development, cognitive development, quality of life and functioning in activities of daily living and participation (self-reported questionnaires).
At present, approximately 180 patients take part.
Desirable outcome
By detailed investigation of the long-term effects we hope to find factors important for the response to enzyme treatment. This will help to implement ‘personalized’ treatment, and aid in the search for (better) future treatment modalities.
