Is porphyria an autoimmune disease?

Acute intermittent porphyria (AIP) is a rare metabolic disorder that is characterized by partial deficiency of the enzyme hydroxymethylbilane synthase (also known as porphobilinogen deaminase). This enzyme deficiency can result in the accumulation of porphyrin precursors in the body.

What drugs cause porphyria?

Does porphyria make you crave blood?

Individuals with congenital erythropoietic porphyria do not crave blood. The enzyme (hematin) necessary to alleviate symptoms is not absorbed intact on oral ingestion, and drinking blood would have no beneficial effect on the sufferer.

Why is porphyria called the vampire disease?

Historically, porphyria has attracted attention as the “vampire disease”. Its symptoms include sensitivity to sunlight and discolouration of the urine. In fact, porphyrias represent a varied group of rare metabolic disorders, characterized broadly into cutaneous and acute forms.

Can porphyria cause weight gain?

“Unfortunately, because of the therapeutic high carbohydrate intake, patients with hepatic porphyrias are prone to weight gain. Losing excess weight is very difficult for some of these patients because of fasting-induced acute attacks.

Why does porphyria cause abdominal pain?

Abdominal pain in the acute porphyric attack has no specific characteristics. It is caused by autonomic nerve dysfunction and frequently is accompanied by nausea, vomiting, and constipation.

How does porphyria affect the body?

Porphyria occurs when the body cannot convert compounds called ‘porphyrins’ into heme. While all tissues have heme, those that use it the most are the red blood cells, liver and bone marrow. Porphyria can affect the skin, nervous system and gastrointestinal system. More women than men are affected by porphyria.

What does a porphyria attack feel like?

The most commonly reported debilitating symptoms are diffuse severe pain affecting the abdomen, back, or limbs; other common attack signs and symptoms include nausea and vomiting, constipation, hypertension, motor weakness, insomnia, or anxiety [1–3, 5].

How do you diagnose porphyria?

Measurement of porphobilinogen, a porphyrin precursor, in urine is the most important test for diagnosing an acute neurological porphyria (AIP, VP or HCP). Measurement of porphyrins in urine and red blood cells is used to detect and diagnose porphyrias that affect the skin (PCT is by far the most common).

Is Porphyria a mental illness?

Acute intermittent porphyria mimics a variety of commonly occurring disorders and thus poses a diagnostic quagmire. Psychiatric manifestations include hysteria, anxiety, depression, phobias, psychosis, organic disorders, agitation, delirium, and altered consciousness ranging from somnolence to coma.

Can porphyria cause elevated liver enzymes?

As reported by Ohtani et al., there have been reports of acute intermittent porphyria causing a mild increase of the liver enzymes and others that report an elevation of transaminases associated with abdominal pain [6, 7].

What can trigger porphyria?

Porphyria can be triggered by drugs (barbiturates, tranquilizers, birth control pills, sedatives), chemicals, fasting, smoking, drinking alcohol, infections, emotional and physical stress, menstrual hormones, and exposure to the sun. Attacks of porphyria can develop over hours or days and last for days or weeks.

Where is porphyria most common?

Acute intermittent porphyria is the most common form of acute porphyria in most countries. It may occur more frequently in northern European countries, such as Sweden, and in the United Kingdom. Another form of the disorder, hereditary coproporphyria, has been reported mostly in Europe and North America.

Does porphyria cause blue urine?

In some cases, porphyrin is excreted in the urine, giving it a purple hue. In rare cases, like George’s, urine is blue. Acute porphyria can seriously affect the nervous system. Symptoms include hallucinations, delirium, insomnia, anxiety and even paranoia.

Can porphyria be cured?

Porphyria is usually inherited — one or both parents pass along an abnormal gene to their child. Although porphyria can’t be cured, certain lifestyle changes to avoid triggering symptoms may help you manage it. Treatment for symptoms depends on the type of porphyria you have.

What is the life expectancy of someone with porphyria?

This depends on the type of porphyria and the severity of symptoms. Most patients with an acute porphyria will not have symptoms or may have only one attack. These patients can live a normal life, particularly if they avoid triggering factors.

Does drinking blood help porphyria?

Interestingly, the heme pigment is robust enough to survive digestion, and is absorbed from the intestine (even though the protein parts of hemoglobin are broken down). This means that, in principle, it is possible to relieve the symptoms of porphyria by drinking blood–another possible link with the vampire stories.

How do you stop a porphyria attack?

Avoiding triggers may include:Not using medications known to trigger acute attacks. … Not using alcohol or recreational drugs.Avoiding fasting and dieting that involves severe calorie restriction.Not smoking.Taking certain hormones to prevent premenstrual attacks.Minimizing sun exposure.More items…•
