The fact that ribes tend to defoliate early here in southeastern NY has never concerned me.  I question whether it's anthracnose at work although I have no specific knowledge on it- only that I assume that once anthracnose has caused defoliation the vascular system would be kaput and all affected canes would be killed, which they are not.
 
I've always assumed that the issue was only that these are cool weather plants as defoliated canes tend to send out small healthy shoots during cool spells.  Anyone with actual information to clarify my assumptions (or contradict them) would be welcome.
