Efficacy of hypothermia therapy in patients with acute encephalopathy with biphasic seizures and late reduced diffusion

Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is characterized by biphasic seizures and impaired consciousness. The efficacy of hypothermia/normothermia therapy in patients with AESD has rarely been reported on. We enrolled 15 patients with AESD admitted to Yamaguchi...

Zusammenfassung:Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is characterized by biphasic seizures and impaired consciousness. The efficacy of hypothermia/normothermia therapy in patients with AESD has rarely been reported on. We enrolled 15 patients with AESD admitted to Yamaguchi University Hospital and Yamaguchi-ken Saiseikai Shimonoseki General Hospital between 2005 and 2019 and retrospectively evaluated the long-term efficacy of hypothermia therapy compared to that of non-hypothermia therapy. We compared the long-term sequelae of patients with AESD treated with or without hypothermia therapy. We used the Pediatric Cerebral Performance Category (PCPC) scale and intelligence tests including the Wechsler Intelligence Scale for Children, Tanaka-Binet Intelligence Scale, and Enjoji Infantile Developmental Scale to evaluate neurological sequelae and mental disability. The preventive effect of hypothermia therapy was assessed based on the development of post-encephalopathic epilepsy (PEE). There was no significant between-group difference in the PCPC score (p = 0.53). The subjects with severe mental disability in the hypothermia therapy group were 0 (0%), while those in the non-hypothermia group were 2 (29%); however, the difference was not significant. Notably, there were no patients with onset of PEE in the hypothermia therapy group, while there were 4 (57.1%) in the non-hypothermia group (p = 0.03). Our study suggests that hypothermia therapy may be effective in the long-term sequelae of AESD in terms of preventing the development of PEE. We propose that hypothermia therapy could contribute to improve the quality of life in these patients by preventing the subsequent onset of PEE.
