Clinical features and management strategies of Meningitis in adult patients: A hospital based study from Kuwait

Abstract

Introduction: High mortality rate of meningitis has been reported in Kuwait, however, limited data is available describing this disease in adult patients. With this background, we conducted a prospective study on patients admitted with meningitis, with an objective to describe the risk factors, clinical presentation, disease course and outcome; focus given on diagnostic problems and consequent management difficulties.
 Methods: Our team diagnosed, managed and documented hospital records of patients (n=44) admitted with suspected meningitis at a referral hospital during 2010-12. Detailed information was collected regarding clinical presentation, CSF analysis, treatment, hospital course and outcome as per Glasgow Outcome Scale (GOS). Results: Bacterial, viral, and tuberculosis (TB) meningitis were seen in 22.8%, 52.3%, and 15.9% of patients. Clinical features of our cohort were consistent with available literature. Positive identification of organism by culture, gram stain, or antigen test was possible in only 6 patients i.e. Streptococcus pneumonae-(n=3), Streptococcus agalactiae-(n=2), Neisseria meningitides-(n=1). CSF polymerase chain reaction was detected positive for Enterovirus RNA, and Herpes simplex virus DNA for one patient each. Empirical antimicrobial treatment directed against common causative organisms was the mainstay of management of bacterial meningitis. Viral meningitis was managed symptomatically. TB meningitis patients were administered anti-tubercular treatment. As per GOS, 38(85.4%) patients recovered with no neurological deficit. Six patients recovered with mild to moderate deficit. Conclusion: Low positive culture rates and inability to identify pathogens have been a diagnostic challenge faced by our team. Strong clinical suspicion, early empiric antibiotic and dexamethasone therapy perhaps contributed to very good recovery in our study.
