Essays on hepatoerythropoietic porphyria

Some people with porphyria-causing gene mutations have latent porphyria, meaning they have no symptoms of the disorder. Symptoms of cutaneous porphyrias include oversensitivity to sunlight blisters on exposed areas of the skin itching and swelling on exposed areas of the skin Symptoms of acute porphyrias include pain in the abdomen—the area between the chest and hips pain in the chest, limbs, or back nausea and vomiting constipation—a condition in which an adult has fewer than three bowel movements a week or a child has fewer than two bowel movements a week, depending on the person urinary retention—the inability to empty the bladder completely confusion hallucinations seizures and muscle weakness Symptoms of acute porphyrias can develop over hours or days and last for days or weeks.

These symptoms can come and go over time, while symptoms of cutaneous porphyrias tend to be more continuous. Porphyria symptoms can vary widely in severity. A health care provider diagnoses porphyria with blood, urine, and stool tests.

A blood test involves drawing blood and sending the sample to a lab for analysis. For Essays on hepatoerythropoietic porphyria and stool tests, the patient collects a sample of urine or stool in a special container.

A health care provider tests the samples in the office or sends them to a lab for analysis. High levels of porphyrins or porphyrin precursors in blood, urine, or stool indicate porphyria.

A health care provider may also recommend DNA testing of a blood sample to look for known gene mutations that cause porphyrias. Treatment for porphyria depends on the type of porphyria the person has and the severity of the symptoms.

A patient receives heme intravenously once a day for 4 days. Glucose loading involves giving a patient a glucose solution by mouth or intravenously. Heme is usually more effective and is the treatment of choice unless symptoms are mild.

In rare instances, if symptoms are severe, a health care provider will recommend liver transplantation to treat acute porphyria. In liver transplantation, a surgeon removes a diseased or an injured liver and replaces it with a healthy, whole liver or a segment of a liver from another person, called a donor.

A patient has liver transplantation surgery in a hospital under general anesthesia. Liver transplantation can cure liver failure. Cutaneous Porphyrias The most important step a person can take to treat a cutaneous porphyria is to avoid sunlight as much as possible.

Other cutaneous porphyrias are treated as follows: A health care provider treats porphyria cutanea tarda by removing factors that tend to activate the disease and by performing repeated therapeutic phlebotomies to reduce iron in the liver.

Therapeutic phlebotomy is the removal of about a pint of blood from a vein in the arm. A technician performs the procedure at a blood donation center, such as a hospital, clinic, or bloodmobile.

A patient does not require anesthesia. Another treatment approach is low-dose hydroxychloroquine tablets to reduce porphyrins in the liver.

People with erythropoietic protoporphyria may be given beta-carotene or cysteine to improve sunlight tolerance, though these medications do not lower porphyrin levels.

Experts recommend hepatitis A and B vaccines and avoiding alcohol to prevent protoporphyric liver failure. A health care provider may use liver transplantation or a combination of medications to treat people who develop liver failure.

Unfortunately, liver transplantation does not correct the primary defect, which is the continuous overproduction of protoporphyria by bone marrow.

Successful bone marrow transplantations may successfully cure erythropoietic protoporphyria. A health care provider only considers bone marrow transplantation if the disease is severe and leading to secondary liver disease. Congenital erythropoietic porphyria and hepatoerythropoietic porphyria.

People with congenital erythropoietic porphyria or hepatoerythropoietic porphyria may need surgery to remove the spleen or blood transfusions to treat anemia.May 01,  · This collection includes essays by and interviews with more than 30 film-makers, both classic and contemporary, on the subjects of their major interests and procedures in making films.

The directors are: Louis Lumiere, Cecil Hepworth, Edwin S. Porter, Mack Sennett, David W. Griffith, Robert Flaherty, Charles Chaplin, Eric von Stroheim, Dziga. Hepatoerythropoietic porphyria (HEP) is associated with a marked deficiency in the activity of uroporphyrinogen decarboxylase. It differs from familial PCT where there is only about a 50% reduction and it can be considered to be a homozygous variant of familial PCT.

Porphyria's Lover - Robert Browning. TASK: Choose a poem in which at least part you found disturbing. Explain what disturbs you and discuss to what extent you find the poem effective in its purpose.

In “Porphyria’s Lover”, Robert Browning dramatically builds intensity and exhibits the decline in the situation’s stability to express the impending doom of the characters’ love.

Hepatoerythropoietic Porphyria (HEP) is a very rare form of hepatic porphyria that manifests as a skin condition.

In this condition, the skin is severely sensitive to light, which often presents as blistering, scarring, and severe disfigurement.

Cutaneous porphyrias include congenital erythropoietic porphyria, erythropoietic protoporphyria, hepatoerythropoietic porphyria, and porphyria cutanea tarda. Other types of porphyria, called acute porphyrias, primarily affect the nervous system.
