Congenital Erythropoietic Porphyria, a skin diseases by inheritance that needs bone marrow transplantation, see its severity
Meaning of porphyria
Porphyrias are basically a group of disease. The problem occurs when there is abnormality in the body in producing porphyrins, a type of chemical. Porphyrins are the crucial chemical to form hemoglobin. Hemoglobin carries oxygen in the red blood cells throughout our body. Hemoglobin is produced by a chain of reactions. The reactions involve conversion of porphyrins to another and in this process a genetic disease occur in the name of “porphyrias”. In the event of a blockage in the chain of reactions, there is a built up of “porphyrin” in the body of the patient, depending on the severity of the blockage. High concentration of porphyrins damages the tissues. Different porphyrias’ accumulations make the severity of porphyrins.

Congenital erythropoietic porphyria and its causes
High levels of porphyrin are found in this condition, known as porphyrinogen, which affect urine bone marrow and blood and become the signs and symptoms.
Does the problem erythropoietic porphyria run through families?
Yes, the carriers of the condition are parent(s). Each of the parents might not have any signs or symptoms of the problem but has the mutation in the genes of either of them. The risk factor is such that 1 out of 4 will carry the 2 abnormal genes from the each parent and develop the health problem. This hereditary condition is termed as ‘autosomal recessive’.
Congenital erythropoietic porphyria & its symptoms
Since the severity of the condition varies, affected people may not have all the conditions together. In many cases, the condition may affect either in early childhood or in the teen agesThe job of platelets is to help blood clots in preventing bleeding and the job of the white cells is to fight all types of infections in the blood. In this condition more risks are caused for infections and bleeding.
• Oosteoporosis that is thinning of bones can also be the symptoms of CEP. The condition is responsible for bone fractures even for minor injuries.
How does congenital erythropoietic porphyria appear to be?
If the blisters are repeatedly occurring, the patient will have bald patches on their scalps and extensive scaring when their skin is exposed to sun. A few patients may have darkening of skin due to the exposure to sun. Some patients may develop excess hair on the back of the hand and on the face.
Diagnosis of CEP
If children (or rare cases of adults) have this problem, the diagnosis is confirmed by measuring the levels of porphyrin in the faeces, urine and blood. All these samples are needed to be kept away from sunlight till they are tested. Changes in the genes are also to be looked for through blood tests.
Pregnant women are not commonly tested for CEP, but exception will be there if there is already a child in the family with the CEP case. In this case cells are taken (for the tests) from the fluids surrounding the baby in the womb (within 3 to 4 months of conception) or from the placenta after the delivery. The test confirms or rejects the cause of CEP due to gene mutation.
Is CEP curable?
Only the bone marrow transplantation is the cure for CEP, as on date. A healthy bone marrow is transplanted from the donor to the person with CEP. If the BMT transplantation is successful, problems like anaemia and photosensitivity will improve, but the previous damages done by the scarring will permanently remain in the skin.
A good match of bone marrow has to be there for the success of the BMT. The procedure of BMT is full of risks. So only those severely affected are considered for this BMT. The donor and the recipient are tested very intensely before the operation, for the best result to come.
The possibility of curing the CEP disease through gene therapy is being extensively researched. The researchers are trying to see the possibilities of correcting the affected person’s abnormal gene. All are keeping their fingers crossed to see the success in the near future. Since mostly the patients are children, the medical problems get attached with the psychological and emotional aspects of the family members, leading to many other unwanted desperations of all the family members of the affected patient(s).
