[Clinical characteristics of pediatric hemorrhagic fever with renal syndrome].

Objective: To study the clinical characteristics of pediatric hemorrhagic fever with renal syndrome (HFRS), and to improve its understanding so as to reduce the misdiagnosis.

Methods: A retrospective analysis was performed on the clinical data of 26 children with HFRS between January 2009 and December 2012.

Results: The age of disease onset was mainly distributed between 7 and 14 years (23 cases, 88%), and the male-to-female ratio was 1.89:l. The clinical manifestations of pediatric HFRS varied. The early symptoms resembled those of a cold, and in the course of HFRS, most patients developed digestive symptoms such as vomiting and abdominal pain. The laboratory examinations usually implicated platelet changes, and the imaging examinations revealed polyserous effusions. The prominent complication was myocardial injury.

Conclusions: Pediatric HFRS mainly occurs in school-age children, more commonly in males. HFRS does not have typical clinical manifestations or symptoms, so it should be distinguished from cold or appendicitis at the early stage. When applying the fluid replacement therapy, the cardiac function should be carefully monitored in case of heart failure.
