dss in dengue

Although intensive efforts have been made to study the early clinical pathophysiology of dengue infection with the objective to identify the potential cause of DHF, results or data that have accumulated from different regions of the world involving studies of different ethnicity groups are inconsistent at present in terms of identifying a unified hypothesis for the pathogenesis of DHF/DSS. The purpose of this review is to identify alternate factors, such as innate immune parameters, hyper-thermal factors, conditioning of neutralizing antibody, concept of vector transmission, and physical status of virus in viremic patients that may play a role in the induction of DHF and DSS, which might have directly or indirectly contributed to the discrepancies that are noted in the literature reported to date. Selon une estimation récente, on compterait 390 millions de cas de dengue par an (intervalle crédible à 95% 284-528 millions), dont 96 millions (67-136 millions) présentent des manifestations cliniques (quelle que soit la gra… As both cell tropism and tissue tropism of DENV are considered major determinants in the pathogenesis of dengue, there is a critical need for adequate tropism assays, animal models, and human autopsy data.

Objective: This study reports clinical manifestations and spectrum of severity of dengue fever (DF), dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS) in adult patients admitted during 2006 outbreak in Karachi. WHO criteria for diagnosis of dengue fever All three of these should be present: 1. DSS, a severe form of dengue infection, is defined as DHF with tachycardia (>100/min), narrow pulse pressure (≤20 mmHg), or hypotension (systolic blood pressure <90 … En plus de la fièvre, des douleurs abdominales et des vomissements, des hémorragies multiples apparaissent sur la peau, les muqueuses et les paroies digestives. The first recorded epidemic of dengue was reported in the late 18thcentury and affected Asia, Africa, and North America. 1996 Dec; 20: 46-50. Figure 2 shows the annual number of reported cases and these numbers clearly indicate the seriousness of the problem in Brazil. The death rate associated with the more severe form DHF/DSS is approximately 5%, predominantly in children under the age of 15. Among these, there are 200,000 to 500,000 cases of potential life-threatening dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS), characterized by thrombocytopenia and increased vascular permeability. More than 2.5 billion … 2007 Sep;30(5-6):329-40. doi: 10.1016/j.cimid.2007.05.010. Fever 2.

More than 50 years of research on dengue … Dengue virus infections may be asymptomatic or may lead to undifferentiated fever; dengue fever (DF) or dengue hemorrhagic fever (DHF) with capillary leakage that may progress to hypovolemic shock; or dengue shock syndrome (DSS), which may be fatal if it is not treated correctly [1, 2]. Compared with non-use, metformin use was associated with a decreased risk of developing severe … Dengue hemorrhagic fever with special emphasis on immunopathogenesis.

Dengue is a spectrum of disease caused by four serotypes of the most prevalent arthropod-borne virus affecting humans today, and its incidence has increased dramatically in the past 50 years. Initial dengue infections maybe asymptomatic or may manifest as a non specific flu-like illness. The common severe syndrome—dengue haemorrhagic fever/dengue shock syndrome (DHF/DSS)—is characterised by sudden vascular permeability generated by cytokines released when T cells attack dengue-infected cells. J Microbiol Immunol Infect. It is the hope that identification of an alternative explanation for the pathogenesis of DHF/DSS will pave the way for the institution of new strategies for the prevention of this complicated disease. Globally, it is estimated that approximate 50 to 100 million new dengue virus infections occur annually. Dengue virus infection has recently taken endemic proportion in India implicating all the four known dengue serotypes. Dengue Hemorrhagic Fever (DHF) is a severe form of dengue fever (DF), which can be life threatening. Thus, the potential mechanisms involved in the pathogenesis of DHF and DSS remain elusive.

Background: Dengue shock syndrome (DSS) is the most severe form of dengue hemorrhagic fever (DHF) and has a high mortality. They may range from subclinical infection to dengue fever, dengue hemorrhagic fever (DHF), and eventually dengue shock syndrome (DSS). Copyright © 2007 Indraprastha Medical Corporation Ltd. The change in disease ecology has resulted in the emergence of dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS) in the region, first with a major epidemic in Cuba, followed by increased occurrence of sporadic cases of DHF/DSS in many countries.
