Abstract
AGUERO ECHEVERRIA, Wilson; ARZA FERNANDEZ, Sonia; AGUILAR, Gloria and RIOS GONZALEZ, Carlos. Validity of diagnostic tools in pediatric patients hospitalized with a presumptive diagnosis of dengue in a Reference Hospital in Paraguay. An. Fac. Cienc. Méd. (Asunción) [online]. 2024, vol.57, n.1, pp.26-36. ISSN 1816-8949. https://doi.org/10.18004/anales/2024.057.01.26.
Introduction:
Dengue is the most common arboviral disease in humans. An early and accurate diagnosis of dengue can support the clinical management, surveillance and control of the disease and is essential, therefore in the diagnosis of dengue it is important to have clinical and epidemiological guidelines that allow timely identification and appropriate therapeutic conduct.
Objectives:
To evaluate the validity of diagnostic tools in pediatric patients hospitalized with a presumptive diagnosis of dengue in a Reference Hospital in Paraguay during the years 2012 to 2020.
Materials and methods:
Analytical study of case and control type, observational, longitudinal, retrospective corresponding to pediatric patients (0 to 18 years) admitted to the Reference Hospital of Paraguay from January 2012 to July 2020 with a presumptive diagnosis of dengue at income. A bivariate analysis was performed relating the frequencies of 20 groups of combined diagnostic criteria and 3 isolated diagnostic criteria (WHO 2009, epidemiological link and NS1 antigenemia for dengue) with the gold standard of diagnosis, which was serological conversion.
Results:
342 subjects participated in the study. 44% were school age and 70% were 5 years old or older. 52.76% (191) were male. Malnutrition and overweight were found in 13% and 2%, respectively. The combination of C-reactive protein with thrombocytopenia was found in 0.45% of patients without dengue and in 6% of patients with a final diagnosis of dengue (p=0.004).
Conclusion:
This result provides the alternative of using a simple combination of laboratory tests that can be replicated in emergency rooms and inpatient wards in a first contact with febrile patients with suspected dengue fever.
