Clinico-aetiological Profile of Meningoencephalitis: A Prospective Observational Study in a Tertiary Care Centre, Hubli, Karnataka, India

Introduction: Meningoencephalitis is a syndrome leading to fatality and neurological damages. Worldwide, infection of the central nervous system is the most common cause of meningoencephalitis. In encephalitis, a leptomeningeal involvement along with inflammation of brain parenchyma is invariably present and the clinical symptoms reflect both diffuse and focal cerebral pathology as well as meningitis. Correct immediate diagnosis and introduction of early symptomatic and specific therapy has a dramatic influence upon survival and reduces the extent of permanent brain injury and also has major impact on the outcome. Aim: To study the clinical profile and aetiological causes of meningoencephalitis and also to analyse the mortality and morbidity due to meningoencephalitis in a tertiary care centre. Materials and Methods: It was a prospective observational study conducted between December 2018 to December 2020 in a tertiary care centre, Karnataka Institute of Medical Sciences, Hubali, Karnataka, in which 184 patients of meningoencephalitis who fulfilled inclusion criteria were included. Detailed history and clinical examination was done followed by laboratory investigations, complete hemogram, serum electrolytes, liver function tests, Fundoscopy, Electroencephalography (EEG). Cerebrospinal Fluid (CSF) analysis including CSF culture and Cartridge Based Nucleic Acid Amplification Test (CBNAAT), Computed Tomography (CT)/Magnetic Resonance Imaging (MRI) Brain were also done and results analyzed. Microsoft (MS) Excel and MS word was used to obtain various types of graphs such as bar diagram, pie diagram. Percentages, means were calculated using Statistical Package for Social Sciences (SPSS) statistics software version 22.0. Results: Out of 184 patients majority of patients were in the age group of 31 to 50 years accounting for 85 (46.2%) of cases. Majority of patients were males (n=113) than females (n=71). Tubercular aetiology was found in 51.6%, viral cause in 25%, bacterial cause in 21.2%, fungal cause in 2.17% of patients. Out of 184 patients of meningoencephalitis, 50% patients recovered, 27.17% patients recovered with residual neurological deficit, 11.95% patients died and 10.86% were discharged . Conclusion: Detailed history and clinical examination along with appropriate investigations are necessary to confirm the diagnosis of meningoencephalitis. The Tubercular (TB) Meningitis was common with high morbidity and mortality.
