PRECIPITATE DEFINITION FOR KIDS SKIN

You may need a stay in the hospital for treatment. During an attack, you may experience dehydration from loss of fluids, breathing problems, seizures or high blood pressure. Acute porphyrias can be life-threatening if an attack isn't promptly treated.Possible complications depend on the form of porphyria: Hormone changes during the menstrual period.Physical stress, such as infections or other illnesses or surgery.Certain medicines, for example, birth control pills, sedatives and barbiturates.This overwhelms the low level of a needed enzyme, setting in motion a process that causes a buildup of porphyrins. When exposed to the trigger, the body's demand for heme production increases.

In addition to genetic risk factors, environmental risk factors may trigger symptoms in porphyria.

Hormones changes during the menstrual period.Viral infections, such as HIV or hepatitis C.Too much iron in the body, often due to a condition called hemochromatosis, which is caused by a gene change.In PCT, certain triggers can cause a buildup of porphyrins that may cause symptoms. Porphyria cutanea tarda (PCT) usually is not passed down in families. This also is the case for most carriers of the changed genes. Just because you inherit a gene or genes that can cause porphyria doesn't mean that you'll have symptoms. Changed genes from both parents (autosomal recessive pattern).A changed gene from one of your parents (autosomal dominant pattern).Most forms of porphyria are caused by a gene change passed down from one or both parents. In acute porphyrias, the buildup affects the nervous system, causing symptoms. When exposed to sunlight, they cause symptoms. In cutaneous porphyrias, porphyrins build up in the skin. Which enzyme is affected determines the type of porphyria. A shortage or change in any of these enzymes causes a buildup of porphyrins. This process involves eight different enzymes that turn porphyrins into heme. Heme is made in the bone marrow and liver. Heme also plays a role in clearing drugs and hormones from the body. Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to all parts of the body. They have a 25% chance of having an affected child with two changed genes.Īll types of porphyria involve a problem making heme. They have a 50% chance of having an unaffected child who also is a carrier. Two carriers have a 25% chance of having an unaffected child with two unaffected genes. Their health is rarely affected because they have only one changed gene. To have an autosomal recessive disorder, you inherit two changed genes, sometimes called mutations. If you have symptoms that could be porphyria, get medical attention. This can make it difficult to know if you're having an attack of porphyria. Many symptoms of porphyria are like those of other, more common conditions.

Repeated exposures can cause thick, leathery skin and scarring. Sun or artificial light exposure quickly results in painful skin burning, irritation and swelling. It's the most common childhood porphyria.

Too much hair growth in affected areas.Įrythropoietic protoporphyria (uh-rith-roe-poi-ET-ik pro-toe-por-FEAR-e-uh), also called EPP, is a rare type of cutaneous porphyria.

Fragile thin skin with changes in skin color.

Blisters on exposed skin, usually the hands, arms and face.

Sudden painful skin redness and swelling.

Sensitivity to the sun and sometimes artificial light, causing burning pain in the skin.

Porphyria cutanea tarda (PCT) is the most common type of all the porphyrias. These forms usually don't affect the nervous system.

Rapid or irregular heartbeats you can feel, called palpitations.Ĭutaneous porphyrias include forms of the disease that cause skin symptoms as a result of sensitivity to sunlight.

Mental changes, such as anxiety, hallucinations or mental confusion.

Muscle pain, tingling, numbness, weakness or paralysis.

Digestive problems, such as constipation, nausea and vomiting.

Severe pain in the belly, chest, legs or back.

Symptoms of acute porphyrias may include: When the symptoms occur they are sometimes called attacks. Intermittent means that the symptoms may go away but return later. The most common form of acute porphyria is called acute intermittent porphyria (AIP). Symptoms appear quickly and can be severe.

Acute porphyriasĪcute porphyrias include forms of the disease that usually cause nervous system symptoms. Some people with a gene change that causes porphyria never have any symptoms. Symptoms also can vary among people with the condition. Symptoms can vary widely by type of porphyria and in how severe the symptoms are.
