METHODS: We reviewed literature from PubMed and Science Direct covering at least one of our objectives from inception to 4th March 2018.
RESULTS: This review represents 6 countries including China, Vietnam, Cambodia, South Korea, Taiwan, and Australia. Fifteen studies with a total of 1043 patients were included. The majority of HFMD cases with neurological complications were reported in China, predominance in boys as compared to girls, with 97% cases under 15 years of age. Meningoencephalitis and brainstem encephalitis contributed 70% of all neurological complications related to HFMD. Human Enterovirus71 genotype C, especially C4a was a causative agent associated with severe complications. Among symptoms, fever, vomiting, myoclonic jerks or seizure, headache, convulsion, and rashes were reported in almost all neurological complications. The common and supportive treatments were the administration of intravenous immunoglobulin and glucocorticoid therapies.
CONCLUSIONS: Early detection and appropriate treatment of severe neurological complications can minimize the risk of adverse health outcomes. Evidence based clinical practice guidelines for early detection and treatment would be significant in the management of these devastating neurological complications.
