Acute hepatic porphyria (AHP) is a rare genetic disorder associated with severe abdominal pain and problems with the central nervous system. It’s a complex disorder, but there are treatment options available. There are also clinical trials for potentially new treatments in which you could participate. Learn about all your options so you’re in-the-know about the latest treatments for AHP.

Hemin injections

In some cases, you may not be getting enough heme to make hemoglobin and carry red blood cells throughout your body. Hemin is a synthetic form of heme that can be injected if your body is producing too many porphyrins. Hemin injections can boost hemoglobin. Injections can also increase myoglobin, which helps maintain your heart and nervous system.

Intravenous hemin

Hemin is also available intravenously. This treatment is usually performed in a hospital setting following an AHP attack. According to the journal Clinical Advances in Hematology and Oncology, patients in the hospital receive up to 4 milligrams per kilogram of body weight over three to four days.

Intravenous hemin may also be used as a preventive measure one to four times per month. Your hematologist may provide the IV at their office.

Intravenous glucose

Getting enough carbohydrates also helps to ensure that red blood cells are functioning. If you have low glucose, a naturally-occurring element in carbohydrates, your doctor may recommend you take glucose intravenously. Milder cases of low blood glucose may be resolved by taking sugar pills.

Phlebotomy

In some cases, hemin treatments can increase your iron levels. Too much iron can trigger attacks. In the case of AHP, a phlebotomy is used to remove excess iron. A phlebotomy involves drawing out your blood to remove harmful elements. Your doctor will need to monitor your iron levels with blood testing to make sure they aren’t too high.

Avoiding triggers

Aside from treating AHP attacks with hemin and glucose, your doctor will also ask you to avoid triggers as part of your treatment plan. Common triggers include:

  • alcohol consumption
  • dieting or fasting
  • excessive iron intake from supplements and food
  • hormone medications
  • infections
  • smoking
  • stress
  • sunlight exposure

Gonadotropin-releasing hormone agonists

The hormone fluctuations during menstruation are common AHP triggers in women. Although fluctuations in hormones are unavoidable, some medications can help if you find your period often triggers your AHP attacks.

Altered sex hormone balance, especially increased progesterone, is associated with AHP attacks. Attacks in women are more frequent in the luteal phase of the menstrual cycle. The luteal phase is the time period after ovulation and before menstruation.

Gonadotropin-releasing hormone agonists can help in this situation. One example is the medication leuprolide acetate (Lupron Depot).

Hospitalization

Hospitalization is a last resort for uncontrollable symptoms of AHP. Your doctor may suggest hospitalization if you experience symptoms such as:

  • breathing difficulties
  • dehydration
  • high blood pressure
  • seizures
  • severe pain
  • vomiting

At the hospital, your doctor will help control these symptoms and monitor you for complications, such as liver damage and kidney failure. Recurring AHP attacks may lead to chronic pain over time.

Exploring clinical trials

Thanks to preventive measures and quick treatments for related attacks, the outlook for AHP has improved over the last few decades. Still, there’s a lot we don’t know about the disorder. Complications like liver and kidney diseases are possible and can lead to shorter life expectancy and reduced quality of life.

When it comes to your treatment plan, consider talking to your doctor about clinical trials for AHP treatments in your area. As a participant, you may be able to try up-and-coming treatments that may help your condition. On a broader scale, you could help other people with AHP, too.
