Resumo
Introduction: In the 21st century, Brazil has become the country with the highest number of cases of dengue in the world, with a wide distribution of Aedes aegypti in all regions and simultaneous circulation of the four serotypes. The identification of the four serotypes is confirmed in Goiânia, which is among the municipalities and cities with the highest concentration of reported cases. Objective: To identify clinical and laboratory markers associated with complications and severe forms of dengue in Goiania, from 2001 to 2011. Methods: A case-control study in which the cases are severe forms (DHF and CCD) and the controls are patients with CD. Secondary data from the Information System for Notifiable Diseases (Sinan) was used, Brazilian Ministry of Health. Verification of consistency, checking and data analysis was performed by the SPSS 20.0 program. Results: 3359 patients aged under 15 years were laboratory confirmed as dengue, with 349 cases and 3010 controls. It did not differ by gender. It is noted an increased tendency to severity, over the years (X2 for trend = 19.03, p <0.0001). Regarding age, the greatest risk of severe forms strata was 5-9 years old (OR 2.32, 95% CI 1.28 to 4.03) and 10 to 14 years old (OR 2.08, 95% CI 1.50 to 2.89). Discussion: Abdominal pain, hypotension and hemorrhagic phenomena such as petechiae, epistaxis and gastrointestinal bleeding were significantly associated with severity after logistic regression. Regarding the laboratory tests available, hemoconcentration, thrombocytopenia and tourniquet test had statistically significant association with CCD and HDF. We identified 10 patients with neurological complications, including 2 deaths. Conclusions: detailed clinical assessment and collection of blood counts are strongly suggested for all patients in the pediatric age group. This study contributed to consolidate the classical signs and ordinary laboratories as important instruments in both the diagnosis, the prognosis of children and adolescents with dengue disease.
