SR5599, I'm sorry you have been dealing with Crohn's for such a long time. It seems to me that in the trial you were hoping to get into, they want a person with nothing going on except Crohn's. Had it been that you had been exposed to hep B, but your immune system knocked it out at the time, your antibody would be POSITIVE. This is the case with me. If you had the vaccination series at some point, you should still have the antibody. There may have been some discussion about your having the vaccination series, but it was never given.
If your GI doc is aware of the trial under discussion, you might ask him if you get the hep B series and have the antibody for B, if you would then be eligible for the trial. Or contact whomever you were dealing with regarding the trial.
If you are excluded from the trial, then it would be a matter of waiting longer to see if the med gets approved and will be available to the general public. I realize that this could take years. I understand your frustration. I was hoping to get the new hep C treatment, but just as it became available I was diagnosed with liver cancer and am being listed for transplant--so that's out of the question for now. And transplant does not rid one of the hep C virus.
Discuss your results with your GI doc, as PG suggested, and perhaps start the hep B series.
Best of luck to you!
