Hep C variant mitigates HIV?

Researchers in Iowa have identified a virus related to Hep C that appears to sheild its victims from the effects of HIV.

…after about six years, the effect of the virus was dramatic. Survival for men who were continuously infected by GBV-C was 75 per cent compared with only 39 per cent for men with no evidence of infection. But the men who faired worst were those who "lost" their GBV-C infection sometime in the first six years – only 16 per cent survived.
