How to Recognize and Manage Symptoms
Fabry disease is a rare genetic condition that affects how the body breaks down certain fats. Over time, these fats build up in the cells, which can damage blood vessels, the heart, kidneys and other organs. While there is no permanent cure yet, several treatments can help slow the progression of the disease, reduce symptoms and improve quality of life. Managing Fabry disease usually involves a combination of medications, therapies and lifestyle changes. Let's look at common treatment options for Fabry disease to ask your doctor about.
1. Enzyme Replacement Therapy
One of the most common treatments for Fabry disease is enzyme replacement therapy, often called ERT. People with Fabry disease either produce little or no alpha-galactosidase A, the enzyme needed to break down certain fats. ERT provides patients with a man-made version of this enzyme through intravenous infusions.
These infusions are usually given every two weeks in a clinic, hospital or sometimes at home with medical supervision. ERT can help reduce pain, slow the progression of kidney and heart problems and increase energy levels. However, it may not reverse damage that has already occurred, which is why starting treatment early is so important.
2. Oral Chaperone Therapy
Another option for some patients is oral chaperone therapy. Instead of replacing the enzyme, this treatment works by helping stabilize the patient’s own enzyme so it can function more effectively. The medication used, called migalastat (brand name Galafold), is taken by mouth and is much more convenient for patients who qualify.
However, this therapy only works for individuals with specific types of genetic mutations, known as “amenable” mutations, which must be confirmed with genetic testing. For those who can take it, chaperone therapy offers a less invasive way to manage the disease and avoid regular infusions.
3. Medications for Symptom Management
Even with ERT or chaperone therapy, many people with Fabry disease still need additional medications to manage their symptoms. Nerve pain is a common problem, and it is often treated with drugs such as gabapentin, carbamazepine or certain antidepressants that also help control nerve-related discomfort.
Protecting the kidneys is another important goal of treatment, and medications like ACE inhibitors or ARBs are frequently prescribed to reduce strain on the kidneys and slow the development of kidney failure. Heart complications are also common in Fabry disease, so patients may need drugs to control blood pressure, regulate abnormal heart rhythms or treat early signs of heart failure.
In more severe cases, devices such as pacemakers or defibrillators may be necessary. Doctors may also prescribe blood thinners to reduce the risk of stroke, which is higher in people with Fabry disease.
4. Dialysis and Kidney Transplant
If kidney damage becomes severe, some patients may eventually need dialysis or a kidney transplant. Dialysis involves using a machine to filter waste from the blood when the kidneys can no longer do the job. A transplant replaces the damaged kidney with a healthy one, and this can significantly improve both survival and quality of life for patients who have reached advanced kidney failure.
While these treatments do not address the underlying cause of Fabry disease, they can extend life and improve overall health outcomes.
5. Lifestyle Changes
Lifestyle adjustments can also make a meaningful difference in managing Fabry disease. Eating a healthy diet that is low in salt helps protect both the kidneys and the heart. Staying well hydrated is equally important, as dehydration can worsen symptoms.
Exercise should be part of daily life, but patients need to be careful not to push themselves too hard, especially if their heart is affected. Light to moderate activities, such as walking, swimming or yoga are often safe and beneficial.
Many people also find that avoiding extreme heat or cold helps reduce nerve pain and other discomfort.
Because Fabry disease is a lifelong condition, taking care of emotional well-being is just as important as physical health. Counseling, mental health therapy or joining support groups can provide encouragement and reduce feelings of isolation.
6. Regular Checkups
Managing Fabry disease requires ongoing monitoring by a team of specialists. Patients may need regular visits with a kidney doctor, a cardiologist and a neurologist to address the different aspects of the condition. Genetic counseling can also be useful for family planning and to help relatives understand their own risks.
By staying on top of medical checkups, patients and their doctors can catch complications early and adjust treatments before major problems occur.
7. New and Emerging Treatments
Research into Fabry disease is ongoing, and several promising therapies are under development. Gene therapy is being studied as a way to provide patients with a healthy copy of the faulty gene so they can produce their own enzyme.
Another area of research is substrate reduction therapy, which focuses on lowering the amount of harmful fat that builds up in the body. While these treatments are not yet widely available, they offer hope for better long-term management in the future.
Symptoms to Watch For
Early recognition is important, since starting treatment sooner can prevent serious damage. Symptoms to look out for include:
- Burning or tingling pain in hands and feet.
- Skin rashes called angiokeratomas (small, dark red spots).
- Reduced sweating.
- Stomach pain or digestive issues.
- Hearing loss or ringing in the ears.
- Episodes of dizziness or fainting.
- Kidney problems, such as protein in the urine or swelling in legs and feet.
- Shortness of breath, chest pain or irregular heartbeat.
Fabry disease can be challenging, but with modern treatments and supportive care, patients can manage symptoms and live fuller lives. From enzyme replacement and oral therapies to lifestyle adjustments and new research, there are more options than ever before. If you or a loved one has Fabry disease, regular monitoring and early treatment are key to staying as healthy as possible.
