Clinical risk factors for dengue shock syndrome in children
Abstract
Background Dengue shock syndrome (DSS) is a seriouscomplication of dengue hemorrhagic fever (DHF) which may
cause death in more than 50% cases if not treated properly and
promptly. Clinical, viral, and epidemiological risk factors
determine the occurrence of DSS. Identifying risk factors for the
development of shock in patients with DHF can increase the
awareness of clinicians to perform a close monitoring.
Objective To determine the clinical risk factors for DSS.
Methods This case control study was conducted on DHF and
DSS patients admitted to the Department of Child Health,
Medical School, University of Padjadjaran, Dr. Hasan Sadikin
Hospital Bandung from January 2004 to December 2005. The
subjects were patients aged less than 14 years who fulfilled WHO
criteria (1997). The exclusion criteria were history of asthma,
diabetes mellitus, sickle cell anemia, typhoid, sepsis, and measles.
The risk factors for DSS were analyzed using chi-square test,
calculation of odds ratio, and logistic regression analysis.
Results Of 1,404 patients with suspected DHF, 600 met the study
criteria; 200 patients of DSS and 400 patients of DHF as control
group were identified. Univariate analysis showed that there was
association between DSS and age 5-9 years (OR=1.67, 95%CI
1.08;2.58), overweight (OR=1.88, 95%CI 1.22;2.90), vomiting
(OR=1.44, 95%CI 1.02;2.04), abdominal pain (OR=2.07,
95%CI 1.46;2.92), and severe bleeding (OR=13.6, 95%CI
5.96;31.03). By logistic regression analysis, it was found that age
5-9 years (OR=1.62, 95%CI=1.03–2.53), overweight (OR=1.97,
95%CI=1.29–3.08), and persistent abdominal pain (OR=2.08,
95%CI =1.44–2.99) were independent risk factors for DSS.
Conclusion Age 5-9 years, overweight, and persistent abdominal
pain are the risk factors for DSS.
