Aspectos clínicos e epidemiológicos da epidemia de dengue no Recife, PE, em 2002

Abstract

RESUMO ABSTRACTThis paper shows data regarding dengue and hemorrhagic fever of the dengue epidemic in Recife in 2002 and the clinical, laboratorial and necropsy results from the 14 patients who died that year. The sorotype Den-3 was detected in 76.3% of cases. The majority of deaths occurred among men, over 20 years old, on the 11 th day of disease, attended in the private hospitals. The average values of the hematocryt and platelets were 40.7% and 56,313p/mm 3 , respectively. Hepatitis, with high levels of transaminases, occurred in the majority of patients, who generally were anicteric. Of the fourteen deaths, 13 received laboratorial confirmation of the infection. In eight cases death occurred due to hemorrhagic phenomena, however, in the other 6 cases significant bleeding was not identified. Vascular collapse (chock) was present in 12 (85.7%) cases, with or without the association of major bleeding, and was the most important cause of death.

Clinical and epidemiological characterization of dengue hemorrhagic fever cases in northeastern, Brazil

“…The hospital lethality rate due to DHF in Recife was 6.8%, with progression to death in around 11 days after the first symptoms 3 . This was close to the data found in the present study.…”

“…An epidemic in Recife showed that the most frequent location for hemorrhages was the digestive tract, followed by the nose and lungs 3 . The most frequent signs were ascites and pleural and pericardial effusion, with 71.4%, 57.1% and 28.6% respectively 3 .…”

“…The most frequent signs were ascites and pleural and pericardial effusion, with 71.4%, 57.1% and 28.6% respectively 3 . Hypovolemic shock was present in 85.7% of the patients who progressed to death 3 . A study conducted in India showed that the most frequent type of bleeding was gastrointestinal (34.5%), followed by petechiae (23.6%) and pulmonary bleeding (13.6%) 13 .…”

“…Over recent years, research has been conducted in order to present an epidemiological profile of dengue and DHF in certain Brazilian cities [2][3][4] . The State of Ceará, in northeastern Brazil, is one of the most important areas in terms of numbers of reported cases of dengue and DHF 5 .…”

Epidemiologia do dengue no Estado do Rio Grande do Norte, Brasil, 2000 a 2009

“…Taxas elevadas também foram registradas no Estado de Pernambuco 14 e na capital, Recife-PE. 15 Os dados obtidos neste estudo mostram que as maiores incidências de casos de dengue coincidem com a estação chuvosa no Nordeste do Brasil, onde tem-se observado um padrão de sazonalidade da doença. Nos meses de maior precipitação pluvial, de fevereiro a junho, em todos os anos estudados, houve aumento na notificação de casos.…”
