This is a longitudinal natural history study of Infantile Pompe disease. The investigators will regularly collect and review medical information regarding the diagnosis of Pompe disease, response to enzyme replacement (ERT) using alglucosidase alfa (Lumizyme/Myozyme) and response to immunosuppressive therapy in cases at risk for developing or those who have developed high and sustained antibodies to ERT. To follow the long-term outcomes, we will collect medical records including but not limited to the diagnosis, clinical parameters, assessments for clinical monitoring, and laboratory values including antibody testing results.
Infantile-onset Pompe disease is an inherited disorder caused by lack of or defect in the enzyme acid alpha-glucosidase (GAA). GAA enzyme deficiency causes glycogen to build up and damage cells throughout the body, especially in the heart and muscles, which is normally diagnosed within the first months of life. Current treatment for Pompe disease involves enzyme replacement therapy (ERT) using the drug alglucosidase alfa (Lumizyme/Myozyme), which provides a form of the GAA enzyme to replace the enzyme that is missing or not working properly in the patient's blood.
In this study, the investigators will learn about the patient's ability to tolerate ERT. Cross-Reactive Immunological Material (CRIM) is a measurement of natural GAA production and an important factor that affects how patients respond to ERT. Children who produce some natural GAA are classified as CRIM-positive, while children who do not produce any natural GAA are classified as CRIM-negative. Children who are CRIM-positive generally tolerate ERT well. But, children who are CRIM-negative, and some children classified as CRIM-positive, have a poor response to ERT due to complications from an immune response against the drug. Treatments are currently being developed to stop this immune response and prevent complications from ERT.
This is a longitudinal natural history study of Infantile Pompe disease. The investigators will regularly collect and review medical information regarding the diagnosis of Pompe disease, response to enzyme replacement (ERT) using alglucosidase alfa (Lumizyme/Myozyme) and response to immunosuppressive therapy in cases at risk for developing or those who have developed high and sustained antibodies to ERT.

|---|---|---|
| Clinical response to enzyme replacement therapy (ERT) using alglucosidase alfa (Myozyme) | Medical records will be tracked until the patient reaches the age of 18 years to follow clinical response to ERT. This will allow us to gain an understanding of CRIM status in relation to clinical outcomes and development for these subjects. | Up to 18 years |
| Measure | Description | Time Frame |
|---|---|---|
| Response to Immune Tolerance Induction (ITI) | Medical records will be tracked until the patient reaches the age of 18 years to follow clinical response to Immune Tolerance Induction (ITI) for patients who are CRIM- or CRIM+ with high antibody titers. This will allow us to increase our understanding of the history of Pompe disease in relation to treatment interventions and the role of high antibody titers in terms of patient outcome in order to develop strategies to ameliorate the immune response and other factors that may affect response to ERT. |
