Spectrum of Neurological Outcomes in Diphtheria: A Case Series.

Diphtheria is an acute infectious disease caused by the exotoxin produced by Corynebacterium diphtheriae, a gram positive bacteria. It has propensity to affect mainly cardiac muscle and nervous system. To study the percentage, spectrum of patients with various neurological complications and the pattern of recovery in followed up confirmed cases of diphtheria. Single centre prospective analysis of neurological complications in diphtheria patients from June 2019 to September 2020 at SMS Medical College and hospital,Jaipur. In this study, 60 cases were included. Immunised cases were 60% (36 out of 60 cases) whereas unimmunised constituted the rest 40% (24 out of 60 cases). Neurological complications were observed in 15% of the cases (9 out of 60). Isolated palatal palsy was the most common complication (4 out of 9 cases, 44.44%), succeeded by lower limb LMN palsies (2 out of 9 cases, 22.22%) with unilateral facial nerve palsy, bilateral abductor palsy and paralytic ileus constituting the rest (1 out of 9 cases each, 11.11% each). Onset of complications ranged from 10 to 36 days whereas recovery was complete and without any residual sequelae between 60 to 240 days. Our study concluded that neurological complications form a sizeable portion of post diptheritic complications and carries good prognosis, hence timely diagnosis and differentiation from other neuropathies is a pre requisite for rational management and contact tracing.
