Porphyria Cutanea Tarda

Porphyria Cutanea Tarda is the common porphyria form, resulting in skin blistering, caused by sunlight.

The disease happens around the world and in the only type of porphyria that is not hereditary. A hepatic porphyria happens when one liver’s enzyme called uroporphyrinogen Porphyria Cutanea Tardadecarboxylase, which is needed for heme synthesis, becomes inactivated. Porphyria Cutanea Tarda may be caused by hepatitis C virus, iron, estrogens, and alcohol. Sometimes, this disorder happens in individual with HIV( human immunodeficiency virus).

Although, Porphyria Cutanea Tarda (hepatic porphyria) is not hereditary, in some cases, the uroporphyrinogen decarboxylase enzyme deficiency inherited from 1 parent, makes an individual susceptible to progress such disorder. In this case, it is called termed familial porphyria cutanea tarda.

The symptoms of the Porphyria Cutanea Tarda include blisters on sun-exposed parts such as face, arms, and the back of the hands. The skin, mostly on the hands, is also sensitive to mild trauma. Scarring and crusting follow the blister and take a long time to heal. Skin injury happens because produced liver’s porphyrin is delivered by the person’s blood plasma to the skin. Face hair growth can increase. The person’s liver is commonly somewhat injured, at times partially, because of excessive alcohol use or infections with hepatitis C virus. Liver cancer and cirrhosis may develop over years.

To diagnose the disorder, the physician tests stool, urine, and blood plasma for porphyrins. The porphyrins levels in Porphyria Cutanea Tarda are higher in the stool and urine. Such disorder is the most readily treated form of porphyria. Most widely recommended procedure is Phlebotomy, where a pint of blood is removed every one to two weeks. It makes the person become slightly iron deficient. The liver porphyrins levels and blood plasma fall slowly and the person’s skin is improving and eventially becoming completely normal. Generally, only 5 to 6 phlebotomies are required; if too many performed, anemia may develop. More phlebotomies are required only if the Porphyria Cutanea Tarda recurring. Using low doses of Hydroxychloroquine or Chloroquene is also helpful. Such medications remove excessive porphyrins amounts from the patient’s liver. However, too high doses of such drugs result in extremely rapid porphyrins removal, causing liver damage and temporary worsening of the Porphyria Cutanea Tarda. Avoiding alcohol is very essential.
