You might want to check out the Hepatitis C and TTP support groups on this website, Yahoo, Multiply, *************.com, etc...
I think this forum is more for other gastro issues. You may find more info at these other support group sites.
I've had chronic ttp (3 episodes, 1988,92,97) and a splenectomy. I did the treatment w/Ribavarin and IntronA for 48 weeks about 10 yrs ago...then tried the Peg/Riba combo twice for a couple of months but had to stop because of side effects and depression.
It did not affect my TTP at all...didn't have a reoccurence of the TTP so I wouldn't worry about it. How many times have you had the TTP? It's a nasty disorder...I got the Hepc in 1988 from the blood products since they weren't testing for it then...
You should be ok.
