Abstract:
Objective:To study the clinical characteristics of purulent meningitis complicated with hydrocephalus in neonates, and to analyze the risk factors of the disease.Methods:Neonates diagnosed with purulent meningitis complicated with hydrocephalus who hospitalized in the department of neonatology of the Second Affiliated Hospital of Wenzhou Medical University from January 2002 to August 2021 were selected as the case group. Neonates with positive pathogen cultures but no hydrocephalus during the same period were assigned by random number table method as the control group. The ratio of the control group and the case group was 2 ∶1. The clinical data such as bacteria distribution, cranial imaging, therapy and prognosis were compared between the two groups. The risk factors for hydrocephalus were predicted. Statistical analysis was conducted using chi-square test and multiple logistic regression analysis.Results:There were 33 cases in the case group and 66 cases in the control group. A total of 27 cases had confirmed pathogen results, of which 20 cases (74.1%) were Gram-negative bacteria and seven cases (25.9%) were Gram-positive bacteria. The time of diagnosis for hydrocephalus were 13.0(5.5, 28.5) days after the onset. Twenty-six cases received non-surgical treatment, while seven cases received surgery. The cure rate of case group was 42.4%(14/33), which was lower than that of control group (72.7%, 48/66), and the difference was statistically significant ( χ2=8.63, P=0.003). Univariate analysis showed that the incidences of protein>3 g/L in cerebrospinal fluid, glucose<2 mmol/L in cerebrospinal fluid, convulsions, central respiratory failure, intracranial hemorrhage and encephalomalacia in the case group were all higher than those in the control group, with statistical significance ( χ2=19.72, 12.04, 19.04, 5.73, 11.85 and 17.48, respectively, all P<0.050). Multivariate logistic regression analysis showed that convulsions (odds ratio ( OR)=4.476, 95% confidence interval ( CI) 1.091 to 18.363, P=0.037), intracranial hemorrhage ( OR=8.031, 95% CI 1.894 to 34.059, P=0.005) and encephalomalacia ( OR=35.189, 95% CI 2.954 to 419.150, P=0.005) were risk factors for neonatal purulent meningitis complicated with hydrocephalus. Conclusions:Gram-negative bacteria are common pathogen of neonatal purulent meningitis complicated with hydrocephalus. Convulsions, intracranial hemorrhage and encephalomalacia are important predictors for neonatal purulent meningitis complicated with hydrocephalus.
