ABSTRACT
Rationale: Guillain Barre syndrome (GBS) is an acute neurological illness leading to quadriparesis with respiratory involvement. It can be triggered by infections, vaccinations, surgery, trauma, transplantation and drugs. Anti-rabies cell culture vaccines introduced to overcome the high rate of neurological complications associated with tissue based rabies vaccine, can be very rarely associated with GBS. Patient concerns: A 50-year-old female presented with acute severe upper back pain evolving into pure motor quadriparesis following administration of human diploid cell vaccine for rabies. Diagnosis: Acute motor axonal neuropathy variant of GBS following anti-rabies human diploid cell vaccine. Interventions: Intravenous high dose steroids. Outcomes: Patient recovered completely within 1 month. Lessons: Although anti-rabies cell culture vaccines are highly immunogenic and safe, they are rarely associated with GBS. Clinicians should be aware of this link because prompt diagnosis and treatment can result in complete recovery and avoid complications.
