Let's learn about the Alglucosidase alfa vaccine for Pompe Disease?

Our body is, to be precise, a very complex, amazing machine. For everything in this machine to function properly, a special type of protein called 'enzymes' is essential. Imagine, sometimes due to genetic reasons, a certain enzyme may not be produced in a person's body or may be produced in a small amount. Pompe Disease is a rare but serious disease that occurs in this way. Today we are going to talk about a special treatment that is given to control this disease, that is, a vaccine called Alglucosidase alfa.

What is Alglucosidase alfa?

Simply put, Alglucosidase alfa is an external injection of the enzyme that is deficient in the body of a person with Pompe disease. This is like bringing in an outside person to do a certain job when an employee is absent. This treatment method is called Enzyme Replacement Therapy (ERT) in medical science.

The most important thing to remember here is that this is not a cure for the disease. However, this treatment can control symptoms, reduce muscle weakness, and significantly improve the patient's quality of life. This drug can be found in the market under brand names such as `Lumizyme` or `Myozyme`.

Things you need to tell your doctor before taking this medicine

Before starting any specific treatment, it is very important to inform your doctor about your complete health history. The more complete your doctor has of your health, the safer and more successful the treatment will be. So, if any of the following apply to you, be sure to mention it.

  • Heart disease: If you have any heart disease or heart-related problems.
  • Respiratory distress: If you have a lung condition or any difficulty breathing.
  • Allergies: If you have any allergies to anything, you should definitely tell us. Especially:
  • If you have previously had an allergic reaction to this medicine or any of its ingredients, such as mannitol.
  • If you have an allergy to hamster or rat proteins (this is important because these are used in the production of some medications).
  • If you have an allergy to any other medicine, food, preservatives or dyes.
  • Pregnancy: If you are currently pregnant, or are trying to get pregnant in the near future.
  • If you are a breastfeeding mother: If you are a mother who is breastfeeding a child.

How is this treatment given?

This medicine is not a pill to swallow, nor is it an injection that can be given at home.

Alglucosidase alfa is an intravenous infusion (IVI). Simply put, it is administered in the same way as a saline solution.

This treatment is only given in a hospital or specialized clinic, under the close supervision of doctors and nursing staff . They will constantly monitor your heart rate, blood pressure, and breathing during the treatment.

Do you give this to small children?

Yes, this treatment can be prescribed even for babies as young as one month old. However, only a pediatrician can make the decision. There are special precautions that must be followed when giving this treatment to a child.

What to do if you overdose?

This is given in a hospital setting, so the chances of this happening are very low. However, if you think you have taken too much of this medicine, inform the medical staff immediately. In an emergency, you can call the National Poisons Information Centre at the Colombo National Hospital . Or you should go to the nearest Emergency Treatment Unit (ETU) .

What if I miss the treatment?

It is very important to attend your scheduled appointment. If for some reason you are unable to attend, do not skip it, but call your doctor or hospital immediately to arrange another date and time.
