True, when there is an infection, it is more stress on the body and sugars tend to creep up. I hope they get good control over those sugars, I know it's hard when your body is going through so much. Maybe when the infection gets better, so will the sugars. I too take lantus but not that much, just 10 units and coverage, but with infection I too notice that I need more insulin. You hang in there, hopefully you are out soon!
