RESUMO
Neurological involvement in the form of meningitis or meningoencephalitis, although well documented in scrub typhus, has not been extensively studied in the pediatric population. We report the clinical and laboratory profile of 96 children with scrub typhus and compared those with and without meningitis. Twenty seven (28%) children had clinical and laboratory evidence of meningitis. The most frequent presenting features were fever (100%), meningeal signs (66.6%), nausea and vomiting (56.3%), seizures (55.5%) and altered sensorium (51.8%). The children with meningitis presented early and had significantly lower respiratory and renal impairments when compared with the non-meningitis group. Cerebrospinal fluid (CSF) analysis revealed elevated total leukocyte count (86.73 ± 94.50 cells/mm(3)), mononuclear pleocytosis (lymphocyte percentage of 76.85 ± 15.86), elevated proteins (108.33 ± 52.63 mg%) and normal CSF glucose (64.18 ± 15.92 mg%). We conclude that meningitis is a common and early complication of childhood scrub typhus. The CSF reveals a lymphocytic pleocytosis, raised proteins and a normal glucose level. These children respond promptly to appropriate antibiotics as do children without meningitis.
