A unique case of human Zika virus infection in association with severe liver injury and coagulation disorders.

ABSATRCT: Zika virus (ZIKV) has caused major concern globally due to its rapid dissemination and close association with microcephaly in children and Gullian-Barr syndrome in adults. In this study, we identified a patient returned from Cambodia who experienced high fever, chill and myalgia. Lab tests discovered sign of severe liver injury including significantly elevated serum transaminases' level, decreased serum albumin level, and markedly increased levels of lactic dehydrogenase, alpha-hydroxybutyric dehydrogenase and creatine kinase in serum. Moreover, severe thrombocytopenia and altered blood levels of fibrinogen and fibrinogen degradation product were also observed, indicating the existence of clotting disorders. A ZIKV strain clustered into the Asian lineage was isolated from the patient's serum. When inoculated into suckling mice, this virus significantly retarded mouse body-weight gain and caused 70% mortality. Our results demonstrate a close association between ZIKV and severe liver injury and coagulation disorders and suggest that clinicians should be aware of compatible symptoms in patients and manage them accordingly.
