Porphyria is a group of disorders that can affect your nerves or skin. While there is no cure for porphyria, treatments are available to help manage your symptoms. In this article, we'll explore the causes, symptoms, diagnosis, and treatment options for porphyria to help you better understand this condition.
Porphyria is caused by a problem with how your body makes a substance called heme. Heme is a crucial component of hemoglobin, the protein in your blood that carries oxygen from your lungs to the rest of your body. When your body doesn't have enough of certain enzymes involved in the heme-making process, porphyrins (chemicals that help make heme) can build up, leading to porphyria.
Most types of porphyria are inherited, meaning one or both of your parents pass a mutated gene to you that leads to the disease. However, some types of porphyria, such as porphyria cutanea tarda, can be triggered by certain conditions or actions, including:
Drinking alcohol
Estrogen use by women
Hepatitis C
HIV
Smoking
The symptoms of porphyria vary depending on the type you have. There are two main categories of porphyria: acute porphyria, which affects the nervous system, and cutaneous porphyria, which affects the skin.
Acute porphyria symptoms can develop quickly and last for days or weeks. These symptoms may include:
Severe abdominal pain
Chest pain
Faster heart rate and higher blood pressure
Limb and back pain
Muscle weakness
Tingling and loss of sensation
Cramping
Vomiting and constipation
Cutaneous porphyria symptoms occur when your skin is exposed to sunlight. The most commonly affected areas include the face, hands, forearms, ears, and neck. Symptoms may include:
Blisters
Itching
Swelling
Pain
Increased hair growth
Skin darkening and thickening
Diagnosing porphyria can be challenging because its symptoms are similar to those of other diseases. If your doctor suspects you have porphyria, they may order blood, urine, and stool tests. These tests are most effective when performed during or around the time of a symptomatic outbreak. Your doctor may also recommend genetic testing, as porphyria often runs in families.
Treatment for porphyria depends on the type you have and the severity of your symptoms. For acute porphyria, hospitalization may be necessary during an outbreak. Treatment may include pain management, anti-nausea medication, and the administration of glucose or hemin injections.
For cutaneous porphyria, treatment options may include:
Regular blood removal (phlebotomy) to lower iron levels in the liver
Low doses of antimalarial drugs, such as chloroquine or hydroxychloroquine
Avoiding triggers that cause outbreaks
Treating underlying conditions, such as HIV or hepatitis C
Managing porphyria often requires a team of healthcare professionals, including hematologists, dermatologists, hepatologists, and genetic counselors. The American Porphyria Foundation (APF) can help you find a specialist in your area.
Porphyria is a chronic condition, meaning symptoms may come and go throughout your life. By avoiding triggers and working closely with your healthcare team, you can manage your symptoms and prevent complications. Remember, everyone's experience with porphyria is different, and treatments can help you feel better and maintain your quality of life.
If you have porphyria, it's essential to reach out to family and friends for emotional support and practical help when needed. Joining a support group, such as those offered by the American Porphyria Foundation, can provide valuable information and connect you with others who understand what you're going through.
