Abstract

Chikungunya (CHIK) has re-emerged as a potential neurotropic virus, with outbreaks recently being reported from many parts of India. The present study was conducted to study the spectrum and outcome of neurological complications in patients of CHIK during the 2016 outbreak in Delhi. A total of 42 cases seropositive for IgM CHIK antibodies by MAC-ELISA and developing neurological complications were enrolled. The male:female ratio was 1:2 (age range = 18–90 years). The neurological manifestations observed were encephalitis (n = 12), bulbar palsy (n = 3), acute disseminated encephalomyelitis (n = 1), cerebellitis (n = 1), myelopathy (n = 1), radiculoneuropathy (n = 3), carpal tunnel syndrome (n = 9) and tremors (n = 1). Ten patients reported worsening of pre-existing neuropathic symptoms of diabetic peripheral neuropathy (n = 4) and carpal tunnel syndrome (n = 6). One patient had aggravation of myasthenia gravis leading to respiratory failure. The majority of patients (n = 32) showed a good outcome; ten had a poor prognosis, out of which four died, all from the encephalitis group, particularly the elderly with co-morbidities.
