RESUMO

Background: Early prediction of severe dengue could significantly assist patient triage and case management. Methods: We prospectively investigated 7563 children with ≤3 days of fever recruited in the outpatient departments of 6 hospitals in southern Vietnam between 2010 and 2013. The primary endpoint of interest was severe dengue (2009 World Health Organization Guidelines), and predefined risk variables were collected at the time of enrollment to enable prognostic model development. Results: The analysis population comprised 7544 patients, of whom 2060 (27.3%) had laboratory-confirmed dengue; nested among these were 117 (1.5%) severe cases. In the multivariate logistic model, a history of vomiting, lower platelet count, elevated aspartate aminotransferase (AST) level, positivity in the nonstructural protein 1 (NS1) rapid test, and viremia magnitude were all independently associated with severe dengue. The final prognostic model (Early Severe Dengue Identifier [ESDI]) included history of vomiting, platelet count, AST level. and NS1 rapid test status. Conclusions: The ESDI had acceptable performance features (area under the curve = 0.95, sensitivity 87% (95% confidence interval [CI], 80%-92%), specificity 88% (95% CI, 87%-89%), positive predictive value 10% (95% CI, 9%-12%), and negative predictive value of 99% (95% CI, 98%-100%) in the population of all 7563 enrolled children. A score chart, for routine clinical use, was derived from the prognostic model and could improve triage and management of children presenting with fever in dengue-endemic areas.

RESUMO

From June 2001 to June 2003, at HCM city Children Hospital N01 and Tien Giang General Hospital, 320 cases of Dengue hemorrhagy were studied prospectively. All cases were dignosed definitely by serology IgM-ELISA HI reaction. Logistic regression analysis showed the related factors for prolonging the dengue hemorrhagic fever shock: age 5-9 years old, fever episode, gastrointestinal hemorrhagy, liver failure, hypoglycemia, hyponatrimia, metabolic acidosis, blood coagulation disturbance, delay of diagnosis, no-accuracy treatment, no proper follow up, tremble with perfusion.
