Abstract:

Objective

To investigate the pathogens types and distribution features among pediatric patients with hand, foot and mouth diseases (HFMD) in Beijing Ditan Hospital, Capital Medical University in 2016, which were combined with clinical data, inorder to furtherly study the characteristics of different types of pathogens infection, and to provide guidance for the diagnosis and treatment of HFMD.

Methods

The throat swabs or fecal samples of 137 patients in Division of Pediatrics in 2016 were collected. Virus RNA was tested by real-time fluorescence quantitative (RT-PCR) kits with universal enterovirus (EV) primers, Coxsackievirus A16 (CoxA16)-specific primers and enterovirus 71 (EV71)-specific primers.

Results

The positive rate of EV71 in 137 cases with HFMD in 2016 was the highest (40.88%). Patients with HFMD mainly concentrated in 6-8 months (62.04%) among children of 1-2 years old (32.12%). The most severe cases were in EV71 positive patients, and the number of hospitalisation days were significantly more than those of CoxA16, non-EV71, non-CoxA16 enteroviruses positive patients. The clinical data of patients showed the most common clinical symptoms of HFMD patients were fever (96.35%); rash/herpes appeared in the hand (93.43%), foot (88.32%), mouth/throat (75.91%) hip (53.28%) and irritable (41.61%). Non-EV71, non-CoxA16 enteroviruses positive patients got a more extensive range of skin rashes than EV71 positive patients. The maximum body temperature of non-EV71, non-CoxA16 enteroviruses positive patients was higher than patients infected EV71 or CoxA16. And EV71 positive patients with encephalitis most easily.

Conclusions

The main prevalent type in 2016 was EV71 which was most likely to develop into severe HFMD. In recent years, the increasing number of cases with non-EV71, non-CoxA16 enteroviruses positive should be paid more attention to prevent new outbreaks.
