Aim: To analyze the clinical features and course of and to define the risk factors for bacterial meningitis in children.
Material and methods: Retrospective study of 100 cases of bacterial meningitis in patients aged 0-18 years admitted to the Iasi Infectious Diseases Hospital between 2005 and 2010.
Results: We found a clear prevalence in male children (58%) from rural area (67%), with the highest incidence in the age group 2-5 years. A significant percentage of patients (43%) had previous hospitalization, condition which is known as predisposing factor for bacterial meningitis, the most common being ear infections (20%) and height and weight deficit (9%). 71% of patients were admitted within the first 48 h. The most common onset clinical manifestations were fever (84%), vomiting (70%), signs of meningeal irritation (59%), somnolence (23%), loss of appetite (19%), and coma in 5% of patients. In 36% of cases CSF was opalescent with moderate pleocytosis (35%); in 29% of patients CSF albumin level ranged between 0.7-1.0 g, the majority presenting normal glycorahia (71%). In only 21% of cases the microbial agent was identified (pneumococcal and meningococcal etiology, 8% and 6%, respectively). The course was generally favorable, and mortality rate was low (5%). Complications occurred in 3% of patients consisting in hydrocephalus and brain abscess.
Conclusions: Bacterial meningitis remains a disease with potentially severe course. Clinical onset, most commonly atypical in children, requires differential diagnosis at the time of admission in order to initiate the most appropriate antibiotic therapy.
