[Acute polyradiculoneuropathy after Chlamydia pneumoniae infection].

A 36-year-old woman presented acute polyradiculoneuropathy following Chlamydia pneumoniae infection. Although electrophysiologic studies were normal, clinical features were typical of Guillain-Barré syndrome (GBS). Anti-ganglioside GM1 antibodies were positive. Two other cases of GBS following Chlamydia pneumoniae infection have been reported, but no specific feature emerges. Outcome was good in our patient after intravenous globulin then antibiotic therapy. Our case supports the notion that Chlamydia pneumoniae infection can induce GBS. The association is probably underestimated.
