عنوان انگلیسی Etiology, clinical findings and laboratory parameters in neonates with acute bacterial meningitis
چکیده انگلیسی مقاله Background and Objectives: Neonatal meningitis is one of the most important and serious neonatal infections with a high mortality and morbidity rate. The present study aimed to investigate the causes, clinical signs, laboratory parameters and mortality rates in newborns with bacterial meningitis. Materials and Methods: This cross-sectional study was performed on 468 neonates aged 2-28 days admitted to NICU in Ghaem Hospital Mashhad, Iran by available sampling method during 2009-2018. Meningitis was confirmed according to positive results of CSF culture and clinical feature. By using researcher-made questionnaire, neonate's individual data including cardiopulmonary resuscitation, the Apgar score of the first and fifth minutes, gestational age, birth weight, clinical symptoms and laboratory data such as ESR, WBC and positive culture of CSF were studied. Results: Among 468 newborn suspected to infection, lumbar Puncture (LP) was performed for 233 cases (50%). Of 233 neonates, 148 neonates (63.5%) had negative results for CSF culture and 85 cases (36.5%) had positive CSF culture. 94% of cases with meningitis were born premature. Blood culture had positive results in 80% of infants with late-onset meningitis and negative in 20%. The most common clinical findings were respiratory symptoms (94%). Klebsiella pneumoniae and Entrobacter aerugenes were the most common microorganisms of meningitis. Gestational disorders were observed in 55.3% of newborns with meningitis. C-Reactive Protein (CRP) of neonates with meningitis was twice higher than normal cases, and leukocytes and proteins in the CSF in neonates with meningitis were higher than healthy ones. Finally, 36% of neonates with meningitis died in our study. For analyzing the relationships between variables, independent t-test was used after controlling the normality, and Chi-square was used for analyzing the relationship of variables with nominal scale. Conclusion: The most common pathogens of meningitis were Klebsiella pneumoniae and Enterobacter aerogenes. Respiratory symptoms were the most common clinical signs, and laboratory symptoms included increased CRP, increased leukocytes and proteins in CSF.
