Predictors of hemorrhagic manifestations in dengue: A prospective observational study from the Hadoti region of Rajasthan

Abstract

Objective: To study the laboratory and clinical predictors of hemorrhagic manifestations in dengue virus-infected patients. Methods: This was a single-center hospital-based prospective observational study. 200 Dengue seropositive patients were included in the study. A detailed clinical examination was done and comprehensive laboratory investigations were done. These parameters were compared between patients with and without hemorrhagic manifestations. Results: Out of the 200 patients, 47 (23.5%) had bleeding. 64.5% Patients were males and 76.0% were under the age of 40 years. The most common presenting symptoms were fever (100.0%) followed by myalgia (77.0%), nausea and vomiting (56.0%). Leukocytosis, neutrophilia, thrombocytopenia, hyperbilirubinemia, transaminitis, decreased serum albumins, and raised D-dimer can serve as hematological, biochemical, and coagulation predictors of hemorrhagic manifestations for dengue. Conclusions: Dengue is a tropical infection with various complications. Bleeding complications are one of them. Laboratory parameters like white blood cells, platelets, bilirubin level, liver enzymes, and D-dimer can help to identify patients at risk for bleeding. Early identification and appropriate management can save a lot of resources and lives.
