Abstract

Dengue infection varies from a mild febrile form to more severe disease with plasma leakage, shock, and multiorgan failure. Several serious complications such as cardiomyopathy, encephalopathy, encephalitis, hepatic damage, and neural manifestations cause organ damage in dengue infection. Splenic rupture, a less well known but life-threatening complication, can occur in dengue. The mechanism of splenic rupture in dengue is still unclear. Optimal therapeutic management is required to save the lives of patients with this complication. The objective of this study was to conduct a systematic review of studies documenting the development of spontaneous nontraumatic splenic rupture in patients with dengue infection. In March 2018, a search was conducted systematically in nine electronic databases, in addition to hand- searching. A total of 127 references were exported to Endnote; 47 references remained after removing duplicates. Finally, 16 reports met the inclusion criteria and represented 17 cases. All articles were evaluated and data extracted according to predefined criteria: number of cases, age, sex, severity of dengue disease, days of illness before admission, methods of definitive diagnosis, timing of the event, and management and outcome. A total of 17 individual patients including 13 males and four females were found. Most of the patients were young adults (ranging from 20 to 52 years) and diagnosed with computed tomography scan and managed with splenectomy. Four cases were fatal. Pathological splenic rupture in dengue is a rare, life-threatening condition where timely management can achieve a favorable outcome.
