The leading causes of death in dengue patients are shock, bleeding, and acute liver injury. We describe the clinical features of patients who died of dengue and discuss the therapeutic challenges and pitfalls of complicated dengue.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>This retrospective study was done in the intensive care unit (MICU) of the National Hospital of Sri Lanka over 30\u00a0months between 2021 and 2023. All patients who died of serologically confirmed dengue were incorporated.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Of the 1722 ICU admissions, 44 (2.6%) patients were treated for dengue\u2014of them, 11 (25.0%) died. Two patients were excluded as their deaths were not directly linked to dengue. Six were females. The average age was 40.2\u00a0years. The leading causes of death included shock (<jats:italic>n<\/jats:italic>\u2009=\u20095), acute liver failure (<jats:italic>n<\/jats:italic>\u2009=\u20096), intracranial bleeding (<jats:italic>n<\/jats:italic>\u2009=\u20092), and pulmonary embolism (<jats:italic>n<\/jats:italic>\u2009=\u20091). Patient 1 had concomitant leakage and bleeding, which did not respond to fluids or blood products. He developed fluid overload and acute liver failure (ALF) and died of multiorgan dysfunction. Patients 2\u20135 were in shock for a prolonged period due to leakage\u2009\u00b1\u2009bleeding. Patients 2\u20135 developed ALF and lactic acidosis followed by multiorgan dysfunction. Patient 8 developed acute hepatitis and ALF without preceding shock. The patient was treated with immunosuppressants for myasthenia gravis. Patients 6 and 7 experienced intracranial bleeding. Patient 9 died of pulmonary embolism after prolonged ventilation for dengue encephalitis.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Prolonged shock, fluid overload and acute liver failure were common causes of dengue related deaths, in our study. Fluid overload occurred when vigorous crystalloid resuscitation was continued in patients who were poorly responding. A prompt switch to colloids or blood could have prevented overload. Patients who were in shock for a prolonged period become unresponsive to fluid resuscitation. How to manage dengue in patients who take anti-inflammatory drugs, immunomodulators, or antiplatelets is not known. Balancing the bleeding risk of dengue in patients predisposed to bleeding or thrombosis is a challenge.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s41182-024-00661-w","type":"journal-article","created":{"date-parts":[[2024,11,29]],"date-time":"2024-11-29T03:53:03Z","timestamp":1732852383000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Nine fatal cases of dengue: a case series from an intensive care unit in Sri Lanka"],"prefix":"10.1186","volume":"52","author":[{"given":"Pramith","family":"Ruwanpathirana","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harindri","family":"Athukorala","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thamalee","family":"Palliyaguru","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Praveen","family":"Weeratunga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dilshan","family":"Priyankara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,11,29]]},"reference":[{"key":"661_CR1","unstructured":"Dengue- Global situation. https:\/\/www.who.int\/emergencies\/disease-outbreak-news\/item\/2023-DON498.
