What are porphyrias Rovich

Introduction

Porphyrias are uncommon diseases that mostly affect the skin or nervous system. These conditions are typically hereditary, which means they are caused by gene changes passed down from parents to offspring.

Porphyria occurs when cells in your body fail to convert chemicals called porphyrins and porphyrin precursors into heme, the material that gives blood its red hue. These substances cause sickness when they accumulate in your body. Porphyrins or porphyrin precursors may accumulate in the liver or bone marrow depending on the type of porphyria you have. Bone marrow is the spongy tissue found inside the majority of your bones.

What are the different types of porphyria?
Porphyrias are commonly classified as either acute or cutaneous porphyrias, depending on whether they affect the nerve system or the skin.

Porphyrias acute
The nerve system is affected by four forms of acute porphyrias. Two of these categories can also have an impact on the skin. Acute porphyria symptoms appear over hours or days and linger for days or weeks.

Table 1. Types of acute porphyria

Porphyrias of the skin

Porphyrias are extremely prevalent.

Porphyrias are uncommon disorders. According to studies, the total number of people affected by porphyrias in the United States is less than 200,000.

Acute intermittent porphyria is the most common kind of acute porphyria.

Porphyria cutanea tarda is the most frequent type of cutaneous porphyria, as well as the most prevalent type of porphyria generally, affecting 5 to 10 persons out of every 100,000.

The most prevalent type of porphyria in children is erythropoietic protoporphyria, a cutaneous porphyria.

Who is more prone to developing porphyria?

Acute porphyria is more common in women than in men and usually begins between the ages of 15 and 45.

Porphyria cutanea tarda is a kind of cutaneous porphyria that most commonly affects men over the age of 40. Symptoms of various kinds of cutaneous porphyria commonly occur in childhood.

What are the consequences of porphyrias?

Different forms of porphyrias can cause a variety of issues.

Problems with the liver

Several forms of porphyrias can harm the liver. Acute porphyria raises the likelihood of developing liver cancer. Porphyria cutanea tarda can cause liver damage and raise the risk of developing cirrhosis and liver cancer. Some persons with protoporphyria suffer liver damage and cirrhosis, and up to 5% of those with the disease experience liver failure.

Bile transfers excess porphyrins from the liver to the gallbladder in persons with protoporphyria, which can result in porphyrin gallstones.

Anemia

Severe anemia can be caused by two forms of cutaneous porphyria: congenital erythropoietic porphyria and, less commonly, hepatoerythropoietic porphyria. These disorders can also cause the spleen to expand, which can exacerbate anemia.

Hypertension and kidney issues

Acute porphyria patients are more likely to develop high blood pressure and chronic renal disease, which can lead to kidney failure.

What are the signs and symptoms of porphyrias?

Porphyrias acute

Acute porphyria symptoms can be moderate or severe, lasting days or weeks. The occurrence of symptoms is referred to as an attack. Without prompt treatment, the symptoms of an attack can worsen and potentially be fatal. Symptoms could include

• Abnormalities with movement-controlling nerves, which can result in muscle weakness, paralysis, and breathing difficulties
• Urinary symptoms include dark or reddish-brown urine, urinary retention, and incontinence.
• When exposed to sunlight, patients with variegate porphyria or hereditary coproporphyria develop skin blisters.
• abdominal, back, or arm and leg discomfort
• Constipation, nausea, and vomiting are examples of digestive symptoms.
• Anxiety, confusion, hallucinations, and convulsions are examples of mental alterations.

Most patients with acute porphyria only have one or two bouts in their lifetime. About 3 to 5% of persons diagnosed with acute porphyria after one attack will have four or more attacks in a year.

Female sex hormones, particularly progesterone, certain drugs, a reduced carbohydrate intake, consuming alcohol, and smoking are all risk factors for acute porphyria attacks or make them worse.

Porphyrias of the skin

Areas of skin exposed to sunlight in patients with porphyria cutanea tarda, congenital erythropoietic porphyria, or hepatoerythropoietic porphyria may develop symptoms such as

blisters weak skin that is easily harmed and slow to heal blister or wound infection scars or changes in skin color
Protoporphyrias, including erythropoietic protoporphyria and x-linked protoporphyria, do not generally create blisters. Instead, sun-exposed skin may exhibit symptoms such as

Pain, burning, stinging, or tingling, as well as redness and swelling.
