Objective: Describe the outcome of a Malaysian cohort of children with acute necrotising encephalopathy (ANE). Method: Retrospective study of children with ANE seen at University of Malaya Medical Centre from 2014 to 2019. All clinical details including ANE-severity score (ANE-SS), immunomodulation treatment and neurodevelopmental long-term outcome were collected. Results: Thirteen patients had ANE and brainstem death occurred in 5. In 10 patients (77%) viruses were isolated contributing to ANE: 8 influenza virus, 1 acute dengue infection, and 1 acute varicella zoster infection. The ANE-SS ranged 2-7: 9 were high risk and 4 were medium risk. Among the 8 survivors; 1 was lost to follow-up. Follow-up duration was 1-6 years (median 2.2). At followup among the 4 high-risk ANE-SS: 2 who were in a vegetative state, 1 remained unchanged and 1 improved to severe disability; the other 2 with severe disability improved to moderate and mild disability respectively. At follow-up all 3 medium-risk ANE-SS improved: 2 with severe disability improved to moderate and mild disability respectively, while 1 in a vegetative state improved to severe disability. Early treatment with immunomodulation did not affect outcome. Conclusion: Our ANE series reiterates that ANE is a serious cause of encephalopathy with mortality of 38.5%. All survivors were in a vegetative state or had severe disability at discharge. Most of the survivors made a degree of recovery but good recovery was seen in 2. Follow-up of at least 12 months is recommended for accurate prognostication. Dengue virus infection needs to be considered in dengue endemic areas.
