A case series of post-infectious chikungunya myeloradiculoneuropathy

Chikungunya fever is an arboviral illness transmitted by mosquito bite of Aedes aegypti and Aedes albopictus caused by chikungunya virus (CHIKV). It is an RNA virus belonging to the genus Alphavirus and family Togaviridae. We present a case series of three patients with chikungunya illness developing para/post-infectious myeloradiculoneuropathy.These patients developed neurological symptoms in the form of bilateral lower limb weakness with sensory and bowel disturbance after the recovery from the initial acute episode of chikungunya fever. Clinical examination findings suggested myeloradiculoneuropathy with normal Magnetic Resonance Imaging of the Spine, with the nerve conduction study showing sensorimotor axonal polyneuropathy. All the patients were treated with 1 g of methylprednisolone once a day for five days, and case 2 was given intravenous immunoglobulin also. In the follow-up, cases 1 and 2 were entirely recovered without recurrence, and case 3 didn't show improvement in one month.
