Integrative Medicine Treatment Options Approach for Porphyria

Porphyria, a group of rare genetic disorders affecting the nervous system and skin, has been a challenge for practitioners and patients alike. The condition affects the body's molecular machinery for making heme, a component of hemoglobin, resulting in the accumulation of porphyrins, compounds that can be toxic in excess amounts. It is estimated that less than 200,000 people are afflicted by these disorders in the United States. However, with its wide array of symptoms and varying degrees of severity, managing and treating porphyria calls for a comprehensive and innovative approach, one that is provided by integrative medicine.


What is Porphyria?

Porphyria represents not one but a collection of eight distinct genetic disorders, each with its own unique characteristics and manifestations. The shared feature across all these variations is the abnormal build-up of porphyrins or their precursor substances within the body. These chemicals, though naturally occurring, do not typically gather in large amounts. The specific chemical build-up varies with each type of porphyria.

The term "porphyrin" and "porphyria" draw their roots from the Greek word porphyrus, translating to purple. This naming can be attributed to the reddish-purple color of the urine in some individuals suffering from porphyria, a result of the excess porphyrins and related compounds. This urine tends to darken upon light exposure. Porphyrias are generally categorized into "acute" and "cutaneous" types, depending on the primary manifestations (1,2).

Acute Porphyrias

The acute variants of porphyria, which include Acute Intermittent Porphyria (AIP), Hereditary Coproporphyria (HCP), Variegate Porphyria (VP), and δ-aminolevulinic acid dehydratase (ALAD) Porphyria (ADP), are characterized by severe, episodic attacks. Though these genetic conditions are rare, with estimates indicating a prevalence of about 1 in 10,000 among Europeans, they span across all races and ethnicities. Interestingly, a large proportion of mutation carriers remain asymptomatic, with only a minority experiencing acute episodes (2). 

Cutaneous Porphyrias

Cutaneous porphyrias primarily affect the skin, causing fragility and blistering in sun-exposed areas. This can lead to infection, scarring, changes in skin coloring, and increased hair growth. Among the cutaneous porphyrias are congenital erythropoietic porphyria (CEP), hepatoerythropoietic porphyria (HEP), erythropoietic protoporphyria (EPP), and porphyria cutanea tarda (PCT). Two forms, hereditary coproporphyria and variegate porphyria, can manifest both acute and cutaneous symptoms, with acute episodes involving a range of symptoms from abdominal pain and digestive issues to muscle weakness, seizures, fever, and mental disturbances (1,2).

What Causes Porphyria?

Porphyria is fundamentally rooted in a disruption of the heme synthesis pathway, a complex, multi-step process and plays an essential role in oxygen transport in our bodies. If any stage of this process is obstructed, an accumulation of intermediary chemicals, porphyrins or porphyrin precursors, occurs. This excessive buildup results from the lack of a specific enzyme needed for heme synthesis, with each type of porphyria representing a different deficiency (2).

Our bodies produce heme under the instructions of a set of specific genes, including ALAD, ALAS2, CPOX, FECH, HMBS, PPOX, UROD, and UROS. Mutations in these genes could result in reduced enzymatic activity, thereby limiting heme production and leading to an abnormal buildup of porphyrins and porphyrin precursors in the liver and other organs. This accumulation can lead to distinct manifestations of porphyria, with cutaneous forms arising from the interaction of these substances with sunlight in the skin, and acute forms resulting from damage to the nervous system (1,3). 

Importantly, during a porphyria attack, metabolic changes can occur that affect the kidneys and the body's hydration and salt levels. Sodium and hydration regulation is therefore essential in the management of porphyria and can be influenced by dietary adjustments. Hence, maintaining optimal sodium intake and hydration status form a vital part of the prevention and management of porphyria attacks.

Risk Factors For Porphyrias

Porphyria's manifestation can be attributed to both genetic and environmental risk factors. Exposure to certain triggers can increase the body's demand for heme production. This surge might overwhelm the limited availability of a required enzyme, initiating a process that leads to a porphyrin buildup. Such triggers encompass exposure to sunlight, certain medications (including birth control pills, sedatives, and barbiturates), illicit or recreational drugs, dieting or fasting, smoking, physical stress (like infections, other illnesses, or surgery), emotional stress, alcohol consumption, and hormonal shifts during menstruation (3,4). 

In the context of genetic predisposition, one is more susceptible to porphyria if a parent has the disorder due to the inheritance of genetic mutations. A different scenario unfolds in the case of porphyria cutanea tarda (PCT), which can be activated when an acquired dormant disease, like hepatitis C or HIV, becomes active. This activation can lead to an enzyme deficiency needed for heme production, subsequently resulting in PCT. Specific factors that might spark PCT mirror the above, and include smoking, alcohol consumption, HIV, chronic hepatitis C, excessive iron levels in the body, estrogen-containing medications, and genetic alterations due to hemochromatosis (a condition leading to excessive iron absorption) (3,4). 

Symptoms of Porphyrias

Porphyria encompasses rare genetic disorders with varying, often misleading symptoms that differ based on the type and individual. Some carriers of the porphyria gene change never exhibit symptoms. Here are the specifics of some types (2,3):

Acute Intermittent Porphyria (AIP): Mostly manifests as abdominal pain, limb discomfort, weakness, vomiting, confusion, and occasionally psychosis. Episodes or 'attacks' may last hours or days, marked by elevated porphyrin precursors PBG and ALA. Sun sensitivity isn't typical.

Variegate Porphyria (VP): Presents skin lesions, light sensitivity, skin fragility, and potentially acute porphyria-like episodes.

Hereditary Coproporphyria (HCP): Features sun sensitivity with usually mild skin disease, with fewer symptoms exhibited in most affected individuals.

Erythropoietic Protoporphyria (EPP): Characterized by light sensitivity and burning upon sun exposure, which usually subsides within a day. Chronic skin lesions and liver dysfunction can occur.

Porphyria Cutanea Tarda (PCT): Displays skin abnormalities similar to VP, such as skin fragility, scarring, blistering, and increased facial hair growth.

Congenital Erythropoietic Porphyria (CEP): A rare type, manifesting soon after birth with dark urine, sunlight-induced blistering, and possibly fluorescent teeth and increased hair growth.

ALA-D Porphyria (ADP): Symptoms arise from nervous system and/or skin effects, including severe abdominal pain, nausea, rapid heart rate, elevated blood pressure, confusion or seizures, and urinary ALA excretion.

Complications of Acute Porphyrias

Acute porphyrias can lead to life-threatening complications if not promptly treated. Common complications during an attack include dehydration from fluid loss, breathing difficulties, seizures, and high blood pressure. Some cases might require hospitalization for treatment. Recurrent acute attacks may lead to long-term complications such as persistent pain, chronic kidney failure, liver damage, or even liver cancer. Erythropoietic porphyria can potentially cause liver failure, necessitating a liver transplant for survival. Furthermore, certain types of acute porphyrias may lead to muscle weakness, which can be life-threatening if it affects the respiratory muscles, thus necessitating hospitalization (3,4).

Complications of Cutaneous Porphyrias

Cutaneous porphyrias can cause permanent skin damage, and the skin blisters may become infected. Healing skin after symptoms may change in appearance and color, become fragile, heal slowly, or leave scars. Furthermore, cutaneous porphyrias may increase the risk of liver damage or liver cancer (3). 

Differential Diagnosis For Porphyria

Accurately diagnosing porphyria is essential to its management. In many cases, this can be challenging due to its similarity to other diseases and low prevalence.

Differential Diagnosis of Acute Porphyrias

Acute porphyrias, a group of rare diseases that affect the liver, often show symptoms that are very similar to other health conditions. These symptoms might include stomach pain, nervous system issues, mental health symptoms, seizures, and liver problems. Because of this, doctors might first think that the patient is dealing with a completely different health issue. For instance, the nerve-related symptoms in acute porphyria can look a lot like Guillain-Barré syndrome, a condition where the body's immune system attacks the nerves. In addition, brain scans of patients with acute porphyria can sometimes look similar to a condition called posterior reversible encephalopathy syndrome, which can cause headaches, seizures, and changes in vision. Adding to this, certain psychiatric disorders can present similarly to acute porphyrias. Symptoms such as feelings of anxiousness, shifts in mood, changes in behavior, and certain personality traits, along with psychosis, can all be associated with porphyria. In some instances, patients with acute porphyria may be initially misdiagnosed with conditions such as bipolar disorder due to the overlap in symptoms. Because of these similarities, doctors need to test specifically for porphyria to make sure they have the right diagnosis.  

Differential Diagnosis of Cutaneous Porphyrias

Cutaneous porphyrias are a group of diseases that primarily cause skin problems due to sunlight sensitivity. When a patient has symptoms that might suggest cutaneous porphyria, doctors have to consider a number of other diseases that can look very similar. For example, a few different types of porphyrias can cause skin problems and also have high levels of certain chemicals called porphyrins in the body. Each of these diseases has a slightly different pattern of these chemicals in the body, which can help doctors make the correct diagnosis. Furthermore, there are other diseases not related to porphyria that can cause blistering on the skin. Although these conditions may look similar on the outside, these diseases don't cause an increase in porphyrins in the body. Additionally, some skin conditions, such as dermatitis herpetiformis, epidermolysis bullosa, and pemphigus vulgaris, can cause blistering on the skin, much like cutaneous porphyrias. However, these skin disorders do not increase the levels of porphyrins in the body. Therefore, testing the levels of these chemicals can help doctors distinguish between these conditions and cutaneous porphyrias.

How is Porphyria Diagnosed?

Porphyria is diagnosed using a variety of laboratory tests, including blood, urine, and stool tests, depending on the type of porphyria suspected. When acute hepatic porphyria is suspected due to abdominal and neurological symptoms, the primary screening tests are urinary porphobilinogen (PBG) and aminolevulinic acid (ALA). If cutaneous symptoms suggest porphyria, a plasma porphyrin assay is typically used. These initial screening tests may be followed by more extensive testing, including urinary, fecal, and red blood cell porphyrins if abnormal results are observed (1,4,7).

DNA testing, or genetic testing, is used to identify specific Porphyria-causing gene mutations and is considered the "gold standard" in diagnosising genetic disorders. This form of testing can confirm a diagnosis of porphyria even in individuals not currently presenting symptoms, as it can detect more than 97% of disease-causing mutations. Once a mutation is identified, other family members can be tested as well to determine if they have inherited the porphyria causing gene, providing critical information for management and prevention of disease complications (1).

Functional Medicine Labs That Can Help Individualize Treatment For Patients With Porphyria Diagnosis?

Functional medicine labs offer a variety of tests that can help tailor treatment to patients, allowing providers to optimize management strategies.

Metabolic Testing for Porphyria

The Access Medical Labs Comprehensive Metabolic Panel is a test that checks various markers in the body. Testing this can help keep an eye on the factors that may change during a porphyria attack, such as salt and waste product levels, which can suggest dehydration or problems with the kidneys. It also checks for signs that your liver may be involved, which is common in porphyria.

Hormone and Stress Testing for Porphyria

The DUTCH Complete Dried Urine test is a special test that checks how your body is dealing with stress and the levels of different hormones in your body. This is important because stress and hormonal changes can affect porphyria. Some women with porphyria may even have more attacks linked to their menstrual cycles. This test can help identify these patterns and help find ways to manage these recurrent attacks. This can provide insight into how the body is coping with stress, which can be a factor in living with chronic diseases like porphyria.


Integrative Medicine Treatment for Porphyria

Integrative treatment for porphyria emphasizes a holistic approach that combines diet, lifestyle, and protective measures to manage the condition. Diet is paramount as it plays a key role in the management of the disease. Regular intake of balanced meals containing carbohydrates, protein, fruits, vegetables, and minimal fats can help stabilize the disease. Of particular importance is maintaining adequate hydration and proper sodium intake to help manage metabolic changes during porphyria attacks. People with acute forms of porphyria, like AIP, HCP, VP, and ALAD Porphyria, should avoid low-calorie diets or prolonged periods without food, as these could trigger attacks. Maintaining a desirable body weight through regular meals and avoiding alcohol, which can exacerbate symptoms, is also advised (14,15).

Nutritional challenges such as nausea and constipation commonly experienced by acute patients can be managed with strategic meal planning and natural remedies. Consuming small meals every few hours, staying hydrated, and focusing on easily digestible foods like carbohydrates are recommended during episodes of nausea. To alleviate constipation, strategies such as regular intake of high fiber foods and maintaining a hydration routine are advised (14,15).

In terms of lifestyle, a significant emphasis is placed on maintaining emotional well-being, as emotional stress has been linked to the precipitation of acute intermittent porphyria. Patients are encouraged to find ways to manage stress and address underlying mental health conditions, such as anxiety or depression, that may arise due to the complexities of managing a long-term health condition. Skin safety and protection from sunlight is also essential for patients with skin porphyrias to prevent skin problems associated with sun exposure. Some ways to protect yourself include using sunscreen, wearing protective clothing, and applying window films to filter out UV (19). 

Those with acute porphyria variants, including AIP, VP, ADP, and HCP, should exercise caution with medications, as numerous drugs can trigger acute attacks. This caution, however, does not apply to individuals with PCT, EPP, XLEPP, or CEP. It is imperative to consult with healthcare professionals when considering any medication or treatment. This applies not only to prescribed drugs but also to over-the-counter medications, tonics, and even herbal remedies, as some of these have been known to induce attacks. Unless the safety of a herbal remedy is guaranteed, it's recommended to avoid them altogether. A list of safe medications was compiled by the UK Porphyria Medicines Information Service (UKPMIS), which the Welsh Medicines Information Centre manages. They created this list for easy reference, ensuring that those with acute porphyria variants have a reliable guide to medicines that won't trigger their conditions (20). 



In summary, porphyria is a rare genetic disorder that affects the nervous system and skin, manifesting in two primary forms, acute and cutaneous porphyrias. Factors such as genetics, lifestyle, and diet can influence its development. Integrative medicine treatments for porphyria prioritize a holistic approach, incorporating personalized lab insights, lifestyle modifications, and dietary adjustments. By leveraging the tools of functional medicine, practitioners can tailor treatment strategies for porphyria patients, mitigating symptoms, preventing complications, and enhancing overall health. This comprehensive approach underscores the importance of personalized care in managing rare genetic disorders like porphyria.
