Hepatitis C Support Group
Hepatitis C is a blood-borne viral disease which can cause liver inflammation, fibrosis, cirrhosis and liver cancer. The hepatitis C virus (HCV) is spread by blood-to-blood contact with an infected person's blood. Many people with HCV infection have no symptoms and are unaware of the need to seek treatment. Hepatitis C infects an estimated 150-200 million people worldwide.
There are reasons not to treat the HCV infection before treating the PCT.

PCT is the most treatable of the porphyrias. Treatment seems to be equally effective in familial and non-familial PCT. Factors that tend to activate the disease should be removed. The most widely recommended treatment is a schedule of repeated phlebotomies (removal of blood), with the aim of reducing iron in the liver. This actually reduces iron stores throughout the body. Usually, removal of only 5 to 6 pints of blood (one pint every one to two weeks) is sufficient, which indicates that iron stores are not excessively increased in most PCT patients. The best guides to response are measurements of serum ferritin and plasma porphyrins. Phlebotomies are stopped when the ferritin falls to - ~20ng/ml. Another treatment approach is a regimen of low doses of either chloroquine (125mg twice weekly) or hydroxychloroquine (100mg twice weekly). Usual dosages of these drugs should not be used because they can cause transient but sometimes severe liver damage and worsening of photosensitivity in PCT patients.
I hope this helps, good luck to you & your brother.
