Yes, I'd be VERY surprised if this guy didn't have some other condition associated with this. And yeah, if you look at AIDS deaths, they've pretty much been attributed to anything you could imagine.
There are also some rather common iron storage diseases that are purely genetic. Hemochromacytoma, for instance, is very common in those of northern European descent. Having all that iron available in the body makes it very easy for microbes to form biofilms and hide from your immune system. I wouldn't be surprised if this were implicated, as well.
Eh, hemachromatosis.... sorry. ;)
