ABSTRACT
Objective@#To analyze the clinical features of death cases of dengue fever and the causes of their deaths.@*Methods@#The clinical data and death reports of nine death cases of dengue fever in Guangdong Province from June 23, 2014 to September 10, 2019 were retrospectively analyzed. All of nine cases were positive for serum dengue virus RNA as confirmed by reverse transcription polymerase chain reaction, and some of the virus strains were serotyped.@*Results@#The median age of the nine patients was 57.5 (range: 18-80) years. Among them, six patients were females; eight patients were local cases and one was imported case; all of nine cases occurred in September and October. The median time from onset to visit hospital and diagnosis was three and four days, respectively. Three of the nine patients had underlying diseases. All of nine cases had fever, including three with double-peak fever. Eight of the cases had three or more severe dengue fever warning indexes before admission. Three cases had severe bleeding upon admission, one case had shock, and six cases had organ failure. Three cases underwent invasive examination, including arterial puncture catheterization, endoscopic titanium clip hemostasis, and percutaneous transluminal coronary angiography. Two cases developed malignant arrhythmia and one had massive hemorrhage of subcutaneous soft tissue after operation. The death cases included four cases of cardiogenic shock and fatal arrhythmia, three cases of encephalitis and encephalopathy, one case of refractory shock, and one case of acute liver failure. Among the six cases that underwent serological typing, four were identified as dengue virus type 1 (DEN-1) and two were DEN-2.@*Conclusions@#Severe organ failure is the major cause of dengue fever-related death, especially fulminant myocarditis, and DEN-1 is most common. Early diagnosis and treatment, and avoidance of invasive procedures can effectively reduce the mortality rate of the severe dengue fever patients.
