First I'd like to say Thank You for taking your time to answer our questions, as I know you must be very busy! My question is.......both me and my husband have HCV and his is much more advanced than mine, as he has "beginning stages" of cirrhosis. He was told a year ago he had Protienuria, but the numbers were down in the 900 range. Now his numbers are up over 2,000 and he needs a kidney cat scan and possible biopsy of the kidneys in the near future. Is this a common illness related to HCV patients? The only way this was described to us is that his kidneys are "leaking" and that when he urinates, he urinates the "Good protien" and the "Bad protien". He is 47 years old and had just finished up a year of Interferon, as a responder who has since relapsed shortly afterstopping treatment. He had sores on both forearms and on the legs that have not come back yet thank God! I was just hoping to get a better explanation of this kidney problem. I hope I've given enough info and hope that you can understand what I'm asking here! Thank you again,
 

One very common scenario here is the development of cryoglobulinemia, a condition that can be due to chronic HCV infection. it can cause kidney damage and cause leakage of protein in the urine. if he has relapsed HCV disease, you may need to think strongly about going back on interferon treatment, but you need to consult with your doctor about this, since this must be done carefully if you have cirrhosis.
