What is the treatment for erythropoietic protoporphyria? There is no cure for EPP. Lifelong photosensitivity is the main problem. Once the pain has started, pain relief can be difficult to achieve.
How do you prevent EPP?
Treatment. The most important treatment for patients with EPP is sun protection. Avoiding or limiting sunlight exposure, as well as any exposure to some forms of fluorescent light, is the best way to prevent and control symptoms.
When was erythropoietic Protoporphyria discovered?
Erythropoietic protoporphyria (EPP) is a type of erythropoietic porphyria and is the most common porphyria found in children. EPP was first clearly defined in 1961 by I.A.
How many people in the US have erythropoietic Protoporphyria?
Erythropoietic Protoporphyria affects males and females in equal numbers. It is estimated that the disorder occurs in about 1 in about 74,300 individuals.
Is Protoporphyria recessive or dominant?
Mode of Inheritance
Erythropoietic protoporphyria (EPP) is inherited in an autosomal recessive manner.
What is the material EPP?
Expanded Polypropylene (EPP) is a highly versatile closed-cell bead foam that provides a unique range of properties, including outstanding energy absorption, multiple impact resistance, thermal insulation, buoyancy, water and chemical resistance, exceptionally high strength to weight ratio and 100% recyclability.
Is Protoporphyria dominant?
X-linked protoporphyria is caused by mutations of the ALAS2 gene and is inherited in an X-linked dominant pattern. Males often develop a severe form of the disorder while females may not develop any symptoms (asymptomatic) or can develop a form as severe as that seen in males.
What are the different types of porphyria?
The specific names of the eight types of porphyrias are:
- Delta-aminolevulinate-dehydratase deficiency porphyria.
- Acute intermittent porphyria.
- Hereditary coproporphyria.
- Variegate porphyria.
- Congenital erythropoietic porphyria.
- Porphyria cutanea tarda.
- Hepatoerythropoitic porphyria.
- Erythropoietic protoporphyria.
What disease can you not be in the sun?
People who have an extreme sensitivity to sunlight are born with a rare disease known as xeroderma pigmentosum (XP). They must take extreme measures to protect their skin from ultraviolet (UV) light. Anything that emits UV light, including the sun and some lightbulbs, can damage their skin.
What is hepatic porphyria?
Hepatic porphyrias are those in which the enzyme deficiency occurs in the liver. Hepatic porphyrias include acute intermittent porphyria (AIP), variegate porphyria (VP), aminolevulinic acid dehydratase deficiency porphyria (ALAD), hereditary coproporphyria (HCP), and porphyria cutanea tarda (PCT).
Is being a vampire genetic?
Dana-Farber/Boston Children’s researchers and collaborators have identified a genetic mutation that may be responsible for vampire folklore. Summary: A newly discovered genetic mutation triggers erythropoietic protoporphyria (EPP).
How do you test for erythropoietic Protoporphyria?
The diagnosis is made upon finding increased levels of the protoporphyrin in the plasma or red blood cells in both EPP and XLP. Genetic testing is useful to confirm the diagnosis. Patients with EPP and XLP may also have mild anemia (low blood counts). In many cases, this may be due to low iron stores.
Does porphyria cause anemia?
Anemia. Two types of cutaneous porphyria, congenital erythropoietic porphyria and, less commonly, hepatoerythropoietic porphyria, may cause severe anemia. These diseases may also cause the spleen to become enlarged, which can make anemia worse.
What causes congenital porphyria?
Erythropoietic porphyria is caused by autosomal recessive inheritance of genes that encode abnormal uroporphyrinogen III synthase (UROS) enzyme protein. The resultant deficient activity of this enzyme leads to hemolytic anemia, cutaneous photosensitivity, and their complications.
What triggers porphyria attacks?
What triggers a porphyria attack? 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.
Is porphyria a mental illness?
Porphyria is important in psychiatry as it may present with only psychiatric symptoms; it may masquerade as a psychosis and the patient may be treated as a schizophrenic person for years; the only manifestation may be histrionic personality disorder which may not receive much attention.
What part of the body does porphyria affect?
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.
Is EPP foam plastic?
Expanded Polypropylene (EPP) is expanded PP. So what is polypropylene (PP)? Polypropylene is a kind of hemicrystalline thermoplastic plastics. Most commercial polypropylene is isotactic and has an intermediate level of crystallinity between that of low-density polyethylene and high-density polyethylene.
What are foam rollers made out of?
When it comes to material, a foam roller can be made of a polyethylene foam, which is softer but can warp over time, or an EVA foam that tends to be denser and a bit more durable. There are also rollers that have reinforced plastic cores to help maintain density and increase their durability.
Does EPP foam absorb water?
5. Resistance to Water/ Moisture: The chemical structure of expanded polyethylene foam makes it almost impermeable. EPE therefore does not absorb water or allow it to pass through.
Is porphyria an autoimmune disease?
The aetiology of porphyria cutanea tarda (PCT) has not been elucidated, but the possibility of an autoimmune mechanism has been proposed. We report a case of an unknown clinical combination of PCT with autoimmune hypothyroidism, alopecia universalis and vitiligo with thyroid and parietal cell circulating antibodies.
Why is porphyria called the vampire disease?
Porphyria cutanea tarda (PCT) is a type of porphyria or blood disorder that affects the skin. PCT is one of the most common types of porphyria. It’s sometimes referred to colloquially as vampire disease. That’s because people with this condition often experience symptoms following exposure to sunlight.
Can people with porphyria have kids?
Almost without exception, female patients with porphyria (of any sort) have normal pregnancies and deliver healthy babies without experiencing acute attacks. However, pregnancy is associated with increased levels of hormones such as progesterone which potentially may aggravate porphyria.
