Scrub Typhus Associated with Guillain-Barré Syndrome (GBS).

Scrub typhus is a vector-borne disease caused by Orientia tsutsugamushi. Clinical manifestations generally occur due to vasculitis and inflammation and can have variable degrees of systemic involvement. Meningoencephalitis and cerebellitis are well-known neurological manifestations of scrub typhus, but the occurrence of Guillain-Barré syndrome is extremely rare. The authors report a 7-y-old boy who developed fever followed by rapidly progressive ascending quadriparesis with areflexia and whose etiological workup revealed positive IgM scrub typhus antibody, as well as, a high OXK titer (1:80). Nerve-conduction studies in all four limbs were suggestive of demyelinating neuropathy. He showed complete recovery after treatment with intravenous immunoglobulin (2 g/kg) and azithromycin.
