Background and purpose: The purpose of this study was to elucidate the association between aseptic meningitis and jolt accentuation of headache (JAH) in adults.
Subjects and method: 87 patients with meningeal irritation (age; 35.6 ± 13.3 years old, 45 males) who were admitted to our hospital from 1st August 2013 to 31st August 2018 were included. The diagnosis was determined according to the following criteria:, aseptic meningitis was defined as cerebrospinal fluids (CSF) pleocytosis with no evidence of bacterial infection, fungal infection or carcinomatous findings; meningism was defined as the absence of CSF pleocytosis. None of these patients had consciousness disturbance and focal neurological abnormalities. The blood and CSF data were reviewed for analysis.
Results: 61 patients were in aseptic meningitis group, 26 patients were in meningism group. Multiple logistic regression analysis showed older age (OR 1.059, 95% Confidence interval (CI) 1.012-1.108, P = 0.013), lower CRP (OR 0.803, 95%CI 0.697-0.925, P = 0.002) and absence of JAH (OR 0.048, 95%CI 0.004-0.554, P = 0.015) were significantly associated with aseptic meningitis. The sensitivity and specificity of JAH in aseptic meningitis were 68.9%, 3.8%.
