Clinical features for 89 deaths of hand, foot and mouth disease in Guangxi, China, 2014.

OBJECTIVES

The aim of this study is to summarize the risk factors of severe Hand, foot and mouth disease (HFMD) and explore the clinical characteristics of pulmonary edema (PE) and non-PE in the deceased patients with HFMD.

METHODS

We identified 89 HFMD deaths which were separated into the PE group or non-PE group. Next, patients were divided based on their initial admission to hospitals as stage 1, 2, 3, or 4; at this point, their clinical manifestations were compared.

RESULTS

There were 87 cases in the PE group, and 2 cases in the non-PE group. In the PE group, the difference in median time for patients at different stages from onset to symptoms, showed no significant difference (p>0.05). The etiology was detected as a positive rate for enterovirus 71 (EV71) of 89.19%, which showed a more severe course than other etiologies. The white blood cell (WBC) counts, lymphocyte (LYM) counts and creatine kinase MB (CK-MB) counts of patients admitted in different stages increased significantly with severity (p<0.05).

CONCLUSIONS

There may be two clinical subtypes, mostly PE and rarely non-PE, in the deceased patients with HMFD. EV71 and risk factors such as an increased WBC count are associated with a severe course of HMFD.
