Dengue infections are imposing an increasing global burden of disease, particularly in tropical countries such as Bangladesh. The World Health Organization (WHO) has identified Dengue virus as a priority pathogen for the development of medical counter measures because of the high risk of it causing a Public Health Emergency of Intenational Concern (PHEIC). Warning signs for severe dengue, associated with mortality, include gastrointestinal features including abdominal pain, vomiting, and diarrhoea. Multiple alterations may occur in in the gastrointestinal tract that could lead to damaging of the gastrointestinal wall and gut leakage, the translocation of gut metabolites into the bloodstream. Study team hypothesize that gut leakage initiates inflammatory processes underlying the further development of severe dengue, including features associated with plasma leakage. This study aims to investigate intestinal barrier dysfunction (gut leakage) in dengue infection by detecting the translocation of gut-derived bacteria and their products (Lipopolysaccharides, LPS binding protein, sCD14, I-Fatty Acid Binding Protein) into the bloodstream. Study team will recruit hospitalized adult dengue patients (18 years and older) presenting with warning signs or severe disease in a tertiary care public hospital at Chattogram, Bangladesh. Circulating biomarkers indicative of gut permeability and microbial translocation will be measured to assess their presence and association with disease severi…
