Abstract: O Dengue vem se constituindo em importante problema de saúde pública, particularmente em países tropicais, nos quais as condições ambientais, com altas temperaturas, períodos chuvosos e alta umidade relativa do ar favorecem sua proliferação. Este estudo tem como objetivo identificar o padrão de ocorrência dos óbitos por dengue no estado da Bahia, no período de 2001 a 2009, com a circulação de três sorotipos do Dengue (DENV1, DENV2 e DENV3). Trata-se de um estudo ecológico, de agregados espaço--temporal, com da… Show more

Introduction:The dengue classifi cation proposed by the World Health Organization (WHO) in 2009 is considered more sensitive than the classifi cation proposed by the WHO in 1997. However, no study has assessed the ability of the WHO 2009 classifi cation to identify dengue deaths among autopsied individuals suspected of having dengue. In the present study, we evaluated the ability of the WHO 2009 classifi cation to identify dengue deaths among autopsied individuals suspected of having dengue in Northeast Brazil, where the disease is endemic. Methods: This retrospective study included 121 autopsied individuals suspected of having dengue in Northeast Brazil during the epidemics of 2011 and 2012. All the autopsied individuals included in this study were confi rmed to have dengue based on the fi ndings of laboratory examinations. Results: The median age of the autopsied individuals was 34 years (range, 1 month to 93 years), and 54.5% of the individuals were males. According to the WHO 1997 classifi cation, 9.1% (11/121) of the cases were classifi ed as dengue hemorrhagic fever (DHF) and 3.3% (4/121) as dengue shock syndrome. The remaining 87.6% (106/121) of the cases were classifi ed as dengue with complications. According to the 2009 classifi cation, 100% (121/121) of the cases were classifi ed as severe dengue. The absence of plasma leakage (58.5%) and platelet counts <100,000/mm 3 (47.2%) were the most frequent reasons for the inability to classify cases as DHF. Conclusions: The WHO 2009 classifi cation is more sensitive than the WHO 1997 classifi cation for identifying dengue deaths among autopsied individuals suspected of having dengue.

Severe dengue cases have increased in Brazil since 2001, with the first records in Maranhão dating back to 2002. The aim of this study was to determine the prevalence of severe dengue cases by age group and the possible risk factors. This was a study of secondary data on dengue in residents of São Luís, Maranhão, Brazil, using probable cases notified to the National Mandatory Reporting System (SINAN) from 2002 to 2011. The diagnosis and classification of dengue were based on the Brazilian Ministry of Health criteria: dengue fever (DF), dengue hemorrhagic fever (DHF) and dengue fever with complications (DWC). DHF and DWC were considered severe dengue, and DF was classified as non-severe dengue. A logistic regression analysis was performed with severe dengue as the outcome. During the study period, 1,229 cases of severe dengue were reported; of these, 812 in patients under the age of 15 (66%). Among the risk factors evaluated, age under 15 years old (OR = 3.10, 95% CI = 2.69-3.57, p-value = 0.001) was associated with severe dengue. The prevalence of severe dengue in children under the age of 15 was higher, and only this age group was associated with the occurrence of severe dengue.

Abstract. Dengue remains a problem in Brazil, and a substantial number of cases that progress to death are not diagnosed by health services. We evaluated the impact of a protocol adopted by the Coroner's Office Rocha Furtado (CO-RF) for the detection of unreported deaths from dengue in Brazil. We evaluated prospectively cases of deaths referred to the CO-RF with suspicion of dengue and those referred with other diagnosis in which the pathologists suspected dengue as the cause of death. Biological material was collected from all bodies autopsied, for which the suspected cause of death was dengue, between January 2011 and December 2012. Of the 214 bodies autopsied, 134 (62.6%) tested positive for dengue; of these cases, 121 were classified as dengue according to the World Health Organization's case definition (1997 or 2009, as appropriate). Thus, CO-RF detected 90 deaths from dengue, which were not suspected during disease progression. This CO-RF protocol, through a combined effort of the surveillance and laboratory teams, increased the detection of fatal dengue cases by 5-fold. This is the largest series of autopsies performed in cases of death related to dengue in the world to date.
