OBJECTIVE: To understand the etiology, clinical prognosis and risk factors of adult community-acquired acute bacterial meningitis (ABM) and provide the evidence for clinical diagnosis and treatment.
METHODS: We performed a retrospective study of 181 clinically diagnosed hospitalized patients with community-acquired adult ABM from Jan.2010 to Jan.2018. The patients were categorized as non-elderly (16≤age<65 years old, n=156 ) and elderly (age≥65 years old, n=25) group. The etiology, clinical features, prognosis and risk factors of the two groups were compared.
RESULTS: Sixty-four of 181 patients (35.4%) had pathogens detected. The most common pathogens were Streptococcus pneumoniae (17.9%), Listeria monocytogenes (13.4%) and Klebsiella pneumoniae (10.5%). The mortality of the elderly group was higher than that of the non-elderly group (P<0.05). Univariate analysis showed that there was a significant difference between the elderly group and the non-elderly group in the incidence of hypertension, hypokalemia, pulmonary infection, ear-nose-throat ( ENT) infection, cerebrospinal fluid (CSF) protein concentration, head CT abnormalities and mortality. Logistic regression analysis showed that pulmonary infection and temperature ≥38.5 ℃ were independent risk factors for poor prognosis in the non-elderly group. CSF pressure ≥200 mmH2O was a independent risk factors for poor prognosis in the elderly group.
CONCLUSION: The pathogens that cause acute bacterial meningitis in adult community are mainly Streptococcus pneumoniae, Listeria monocytogenes and Klebsiella pneumoniae.Pulmonary infection and temperature ≥38.5 ℃ are independent risk factors of poor prognosis in the non-elderly patients, as CSF pressure ≥200 mmH2O a independent risk factor in the elderly patients.
