    Abstract:
    OBJECTIVE: To study the clinical and laboratory features of the mild and severe hand-foot-mouth diseases (HFMD) in Shenzhen in 2008. METHODS: 145 cases were observed in East-Lake Hospital and Shenzhen Children's Hospital. Of the 145 cases, 124 mild cases and 21 severe cases were involved.All the clinical data and laboratory findings were collected and summarized. After collection of the acute and convalescent consecutive stools and peripheral bloods from the patients with HFMDI, EV71 genes were amplified from these samples by RT-PCR. Enterovirus 71 were cultured and isolated using Vero cell line and R&D cell line. RESULTS: The WBC counts and blood glucose levels of the severe cases were significantly elevated, but the ages of the severe ones significantly decreased compared with those of the mild cases (P < 0.05). EV71 genes could be detected by RT-PCR with 35% positive rate in mild cases and 67% in severe cases. The EV71 gene detection rate of the severe cases was significantly increased in contrast to that of the mild ones. The EV71 were isolated and cultured from the stools of 9 patients, one specimens from the dead's stool. Two severe cases died of neurogenic pulmonary edema and brain-stem encephalitis. CONCLUSIONS: EV71 mainly contributes to HFMD and is responsible for death of some severe cases. High fever, less rash, elevated white blood cell counts and blood glucose concentrations as well as age less than 4 years old should be used for prediction of severe cases.
