Porphyria – Diagnosis and Treatment

ByJanis Updated

Diagnosis

Diagnosing porphyria can be challenging because symptoms like abdominal pain, chest pain, muscle weakness, or neurological signs often look similar to other conditions.

Health professionals use specific laboratory tests to identify the disorder and its type.

Main diagnostic steps include:

  • Blood, Urine, or Stool Tests: These tests measure levels of porphyrins and related chemicals that are part of the heme biosynthetic pathway.
  • Genetic Analysis: This process finds inherited enzyme deficiencies or determines if acute intermittent porphyria (AIP), porphyria cutanea tarda (PCT), variegate porphyria, or hereditary coproporphyria is present.
  • Family Assessment: Clinicians may offer genetic counseling and testing to family members, especially if inherited forms are suspected.

If there is a family history or unexplained symptoms related to metabolic disorders or hemoglobin production, testing becomes especially important.

Treatment

Steering Clear of Known Triggers

People with porphyria need to watch out for certain situations and substances that can make their symptoms worse. They should work closely with a healthcare provider to get a clear list of medicines and supplements to avoid.

Some drugs, herbal remedies, and even over-the-counter products may cause attacks.

Other key steps include not smoking, limiting alcohol use, and avoiding illegal drugs. Fasting and strict diets with very low calories are risky, too, since they can bring on symptoms.

For those with skin problems, reducing sun exposure is important. They should use protective clothing, window filters indoors, and sunscreen that physically blocks light, like those with zinc oxide.

A high SPF should be used for different amounts of sun time:

Sun Exposure Recommended SPF
Short/limited SPF 30+
Long/outdoors SPF 50+

Treating infections quickly, managing stress, and planning with a doctor—especially for women with premenstrual attacks—are all part of daily care.

Treating Sudden Porphyria Episodes

Acute porphyria symptoms can appear suddenly and may be severe. Patients may need immediate care at a hospital. Several treatments can help:

  • Hemin Injections: Doctors use hemin to lower the amount of porphyrins in the body and ease symptoms during an attack.
  • Glucose: Medical staff may provide sugar through an IV or by mouth, depending on the patient’s condition. Increasing carbohydrate intake can also help lessen attacks.
  • Hospital Treatment: Some attacks cause pain, vomiting, dehydration, or trouble breathing, so a hospital stay may be necessary to control symptoms.

Doctors may also prescribe a liver-directed RNA interference therapy for some adults with acute hepatic porphyria.

This type of treatment reduces the liver’s production of porphyrins, potentially decreasing the frequency of attacks. Patients should discuss the risks and benefits with their healthcare provider.

Managing Skin-Related Porphyrias

Cutaneous porphyrias mainly affect the skin, so patients should avoid sunlight. They should use sun-protective clothing and sunscreen, and avoid being outdoors during peak sunlight hours.

Lowering the body’s porphyrin levels also helps:

  • Phlebotomy (Blood Removal): Doctors remove blood at regular times to lower iron and reduce porphyrin buildup.
  • Medicine: Doctors may sometimes use antimalarial agents to help the body eliminate excess porphyrins. These medications are generally considered when therapeutic phlebotomy (blood removal) is not an option. Treatment should be carefully monitored, as dosing needs to be precise to avoid adverse effects.
  • Vitamin D Supplements: People avoiding sunlight may need extra vitamin D.

For erythropoietic protoporphyria (EPP), some treatments are more specific to light sensitivity. High doses of beta-carotene, a dietary antioxidant, may help protect the skin by increasing tolerance to sunlight.

In some cases, melanocortin receptor agonist implants are used to gradually increase melanin levels, providing additional photoprotection.

Patients should consult with their healthcare provider to weigh the benefits and discuss potential side effects or safety considerations.

Everyday Tips and Self-Care

People living with porphyria can reduce symptoms by taking steps at home and in daily life. Common steps include:

  • Learning about what might set off their symptoms, such as certain medicines, stress, or sunlight exposure.
  • Sharing information about their porphyria with all healthcare providers so treatments and surgeries can take it into account.
  • Wearing a medical alert bracelet or necklace that mentions porphyria for safety.
Self-Care Step Reason
Avoiding direct sunlight Prevents skin flare-ups
Managing mental stress Lowers risk of symptom triggers
Notifying providers Helps prevent harmful treatments

Getting Ready for Your Doctor Visit

Steps You Can Take Beforehand

Getting organized before a medical appointment helps make the visit more productive. Here are a few things to do ahead of time:

  • List all symptoms. Write down anything unusual, even if it seems unrelated.
  • Collect photos of rashes. Bring clear photos if any skin problems have appeared, especially if they are not visible during your visit.
  • Note important events. Jot down major personal changes or recent stresses, as these might connect to your symptoms.
  • Bring all medications. Make a list or take a photo of all medicines, supplements, herbs, and vitamins you are using. Remember to include the exact doses.
  • Prepare questions. Write down anything you want to ask. Possible questions include:
    • What could be causing these symptoms?
    • Are there other likely reasons?
    • What tests will I need?
    • What are my treatment options?
    • If there are alternatives, what are they?
    • How should I handle another health problem along with this one?
    • Are there any restrictions I should follow?
    • Is genetic testing necessary? Should my family get tested as well?

Use this table to keep track:

What to Bring Details
Symptom List Unusual feelings, rashes, timing
Medication/Supplement List Names and doses
Key Personal Info Stress, lifestyle changes
Questions Ask about causes, tests, and treatment
Photos Pictures of any skin changes

Questions Your Health Provider May Ask

During the appointment, the doctor may ask for details on your symptoms and family history. Typical questions include:

  • When did the symptoms start?
  • Are the symptoms always there or do they come and go?
  • Is there anything that helps or makes symptoms worse?
  • Does anyone else in your family have similar issues?
