BACKGROUND: Meningitis is a life threatening central nervous system infection that is prevalent worldwide. Many studies have been conducted on bacterial meningitis, but the information is inadequate on the other types of meningitis, especially prevalent in India. Regional information regarding trends, in terms of etiology and microbiological susceptibility, are essential for timely and adequate management of meningitis. AIMS: The present study was undertaken to evaluate the changing epidemiology of meningitis by reviewing the causative agents, the available laboratory methods for making the etiological diagnosis, the risk factors and the clinical outcomes, and the management of meningitis in our patient population. MATERIALS AND METHODS: It is an observational study conducted at a tertiary care centre. A structured data form was designed to collect the information from the medical records and charts of medical investigations of the patients. Details regarding etiological agents, prevalence of clinical features and management were recorded and interpreted. RESULTS: A total of 147 patients suspected to be having meningitis were included. The common types of meningitis in our study were aseptic (39%), tuberculous (28%), pyogenic (28%), fungal (3%) and others (2%). The classical triad of headache with fever, neck stiffness, and altered mental sensorium was seen in 26% patients, and 83% had at least 2 out of these 4 symptoms. The incidence of seizures was found to be 63% in the presence of aseptic meningitis. Significant clinical improvement was seen in 89% of the patients suffering from aseptic meningitis. CONCLUSIONS: Aseptic meningitis was found to be the predominant type among all different varieties of meningitis. An increased incidence of meningitis was seen in patients with diabetes mellitus. The incidence of seizures was high in viral/aseptic meningitis. The empirical treatment given in most of the cases was ceftriaxone. Isolation of the culpable organisms was possible in a very few cases due to the usage of empirical antibiotics prior to the performance of the lumbar puncture for the diagnostic analysis of the cerebrospinal fluid.
