Variegate Porphyria

Variegate porphyria (VP) is an inherited malady of porphyrin-heme metabolism developing from mutations of the gene encoding the enzyme protoporphyrinogen oxidase. As a consequence, protoporphyrin is accumulated in the tissues and there is increased excretion of protoporphyrin and coproporphyrin in the stools. Significations of VP in any given individual may include cutaneous photosensitivity, systemic symptoms arising from neurologic dysfunction, or both. Haeme is a vital molecule for all of the body's organs. It is a constituent of haemoglobin, the molecule which carries oxygen in the blood.

Severe invasions usually begin in adulthood and cause abdominal pain, vomiting, diarrhoea, and constipation. These hallmarks and symptoms are triggered by nongenetic factors such as certain drugs, dieting or fasting, certain hormones, and stress. Areas of skin revealed to the sun develop severe blistering, scarring, changes in pigmentation, and increased hair growth. In such cases, the signs and symptoms are normally more acute than those initiating later in life. In summation to the health complications described above, children with this disorder may have mental retardation and grow more slowly than other children.

Variegate porphyria is a kind of porphyria which can have acute (serious but generally not long-lasting) symptoms along with symptoms which affect the skin. The imperfect gene is located on chromosome number 1 and is inherited in an autosomal dominant fashion. It is comparatively common in the white African population of South Africa.

The neurovisceral exigences give symptoms similar to those of patients suffering from AIP, while the photodermatitis shows the typical findings of the standard nonspecific form of skin sensitivity to solar radiation. The precipitating factors are also alike to those of AIP although some experts feel that the severe attacks of VP are not associated to menstrual cycles. There are increased porphyrins in the urine with coproporphyrins excreted in excessive of uroporphyrins.

Many people who are asymptomatic bearears of the abnormal gene will systematically have negative laboratory tests. The enzyme PPO is not found in red cells and is technically very complicated to measure. The treatment of the neurovisceral attacks is same to that used in AIP, including the superintendence of hematin. If both parents carry the abnormal gene so that the patient is homozygous, the disease will observed in early childhood and be rather severe.

Symptoms of Variegate Porphiyria

Some Symptoms of Variegate Porphiyria :

• Abdominal and/or back pain
• Urine of "some" patients is a purple-red color.
• Mood swings
• Increased hyperactivity
• Nausea and or vomiting
• Constipation (at times)

Treatment of Variegate Porphiyria

Here is list of the methods for treating Variegate Porphiyria :

• Treatment of the consistent symptoms of variegate porphyria is tantamount for that acute intermittent porphyria.
• Skin lesions are conducted in a similar way to those of porphyria cutanea tarda patients.
