RESUMEN
Acute virus-associated encephalopathy induces seizures. Serum N-terminal pro-B-type natriuretic peptide (NTproBNP) levels are elevated following febrile and afebrile seizures. However, the role of NTproBNP in acute virus-associated encephalopathy pathology is unknown. We enrolled 10 patients with acute virus-associated encephalopathy and convulsions (E group: 7 boys, 3 girls; median age, 3.10 ± 1.92 years) and 130 patients with febrile seizure (FS group: 80 boys, 50 girls; median age, 3.23 ± 2.44 years). The E group had significantly higher NTproBNP levels (345 ± 141 pg/mL) compared with the FS group (166 ± 228 pg/mL) (P < .0005). Furthermore, subjects with prolonged seizure within the E group had significantly higher NTproBNP levels (303 ± 107 pg/mL) compared with subjects with prolonged seizure within the FS group (134 ± 100 pg/mL) (P < .005). Our findings suggest that serum NTproBNP levels are increased during the acute phase of acute virus-associated encephalopathy associated with convulsion.
