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.\n\nThis 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 severity.\n\nAbdominal ultrasonography will be performed to characterize gastrointestinal alterations and determine their correlation with biochemical markers of gut leakage and clinical severity. In addition, study team will analyze the gut bacteriome from stool\u002F rectal swab of these patients to explore whether dengue infection induces compositional changes in intestinal microbiota and whether such alterations are linked to gut leakage or disease progression.",[26,27,28,29,30,31],"Dengue","Dengue Hemorrhagic Fever","Intestinal Disease","Ascites","Dengue With Warning Signs","Gut Microbiome","NOT_YET_RECRUITING","2026-06-08",{"date":35,"type":36},"2026-06-10","ACTUAL",{"date":38,"type":22},"2026-07-01",{"date":40,"type":22},"2028-01-31",{"name":42,"class":43},"University of Oxford","OTHER"]
