Not a lot. They are grown prolifically because they are such a successful species. They can get Honey fungus or Coryneum canker as well as suffer some die back from aphids, but so do many trees. Generally they are trouble free.
Leylandii (now called x Cupressocyparis leylandii) don't trim back very well though and have to be kept on top of annually to keep in shape. Thuja are more tolerant of pruning and are a similar tree choice for hedging.
The greatest Leylandii pest is the one who plants it along a neighbour's boundary and lets it achieve its full height! Which for interest's sake is 120ft x 15ft! Why aren't they licensed?
Hope this is of some help.

Only problem is neighbours!
Be considerate.
