Hello Tatty,
We do suspect that your immune system still plays a role but it’s small. The evidence suggestive of this includes past treatment failures (Peg/Riba) being harder to treat and VL > 6 million treatment naive GT1 needing 12 rather than 8 weeks.
That said the cure rates for HIV positive people don’t seem to be reduced.
So in short nobody really knows what the impact of cyclosporin might be. Optimists would say none, pessimists would say a lot.
What is useful is an observation from both Egypt (unpublished) and the USA (published) that notes in the Egyptian case that a 4 log drop by the end of week 1 indicates 12 weeks will work, and in the US case that being detectable at week 4 reduces a 92% SVR in GT1 patients on Harvoni by 8-10%.
So if you are undetectable I would suggest being happy and leaving things as planned with 12 weeks treatment. In NOT undetectable then consider extending the duration by 4 or more weeks.
.
I’ll phone Wednesday and find out if my results are back, with fingers tightly crossed in the mean time.
