Pompe disease is a rare and progressive genetic disorder that affects the muscles, heart and breathing. The disease is caused by a deficiency in an enzyme called acid alpha-glucosidase (GAA), which leads to the accumulation of a complex carbohydrate called glycogen in the lysosomes of cells. This excess glycogen interferes with normal cellular function and causes cellular damage and death, leading to progressive muscle weakness and wasting, as well as other symptoms such as heart and respiratory problems.
There is currently no cure for Pompe disease, but several Pompe Disease Therapeutic options are available that can help to manage the symptoms and slow the progression of the disease.
Pompe Disease Therapeutic include:
Enzyme replacement therapy (ERT): ERT involves the administration of a recombinant form of the missing GAA enzyme. The enzyme is administered intravenously, typically on a bi-weekly basis, and helps to clear the excess glycogen from cells. This leads to a reduction in cellular damage and improved muscle function, as well as improved heart and respiratory function in some cases.
Substrate reduction therapy (SRT): SRT works by reducing the production of glycogen in the cells. The goal of this therapy is to decrease the amount of glycogen in the lysosomes, which reduces the cellular damage caused by the accumulation of this carbohydrate. SRT is usually administered orally and is typically used in conjunction with ERT.
Gene therapy: Gene therapy aims to replace the missing or defective gene that causes Pompe disease with a functioning copy of the gene. This approach is still in the experimental stages and is not yet widely available, but early results have been promising and have shown improved muscle function and heart and respiratory function in some cases.
Physical therapy and rehabilitation: Physical therapy and rehabilitation are important components of managing Pompe disease. This type of therapy involves exercises and activities to maintain and improve muscle strength, flexibility, and mobility. Rehabilitation may also include the use of assistive devices such as wheelchairs, braces, and oxygen support, as well as the management of heart and respiratory problems.
