Guillian-Barre Syndrome after Preceding Shingles

Guillain-Barre Syndrome (GBS) has been known to be preceded by various infections such as Campylobacter jejuni, cytomegalovirus, and so on. We have experienced a case of GBS after a preceding herpes zoster, which was complicated by GBS, which is rare. Some circumstantial and experimental clues suggest a possible causal relationship between those two. Here we report the case along with a literature review.
