Diagnóstico tardio de malária em área endêmica de dengue na extra-Amazônia Brasileira: experiência recente de uma unidade sentinela no estado do Rio de Janeiro

Abstract: INTRODUçãO RESUMOIntrodução: A letalidade da malária na região extra-amazônica é cerca de 80 vezes maior do que na Amazônia, que concentra 99,8% dos casos do país. Em áreas de transmissão de dengue, como o Rio de Janeiro, o atraso no diagnóstico e tratamento da malária dos pacientes com febre, provenientes de áreas endêmicas de malária, pode ser, entre outros fatores, devido à confusão entre o diagnóstico das duas doenças pelos generalistas da rede de assistência médica. Neste trabalho, apresentamos as consequ… Show more

“…According to national statistics, there were three deaths in the region of Campinas during the study period, resulting in a lethality rate that was similar to that of the State of São Paulo. Although the lethality of the cases in Brazil that occurred outside of the Amazon Region in our study differs from previous studies [2,3], in which an 80 to 100 times higher lethality rate was reported, the findings in this study still support the notion that cases in non-endemic areas of Brazil are associated with an augmented risk of complications.…”

“…Therefore, although the clinical outlook for malaria in previously healthy adults living in endemic areas tends to be mild, the absence of immunity and delayed or misdiagnosis (up to 40% [1]) may predispose infected persons to more severe presentations in imported cases of disease. Indeed, the chances of death are 80 to 100 times higher for malaria cases diagnosed outside of endemic areas [1-3]. …”

“…Para Costa et al 20 , os sinais e sintomas da malária são constituídos, principalmente, por uma tríade clássica composta por febre-calafrio-cefaleia. No entanto, Rosas 21 alertou para a familiaridade desses sintomas com outras doenças febris, como dengue, febre de Chikungunya e febre por Zika vírus.…”

“…Despite the circulation of two serotypes (DENV-1 and 2) and the fact that 7 to 11% of the study population were infected by both DENV-1 and 2, no Dengue Hemorrhagic Fever (DHF) case has been reported in the country. The lack of records of occurrence of DHF in Cameroon and in Gabon [11] may be due to the confusion of DHF with clinical malaria by non-specialists medical personnel among other factors [28]. Discussion on the low incidence of DHF in Africa has been quite intense in the literature and African ancestry appeared to be relatively protective for severe forms of dengue but not for classic dengue fever [21], [29].…”
