Dengue-induced Acute Kidney Injury (DAKI): A Neglected and Fatal Complication of Dengue Viral Infection--A Systematic Review

J Coll Physicians Surg Pak. 2015 Nov;25(11):828-34.


Dengue Viral Infection (DVI) imperils an estimated 2.5 billion people living in tropical and subtropical regions. World Health Organization (2011) guidelines also classified dengue as 'Expanded Dengue Syndrome' to incorporate wide spectrum of unusual manifestations of dengue infection affecting various organ systems - including liver, kidney, heart and brain. Renal involvements are least appreciated area of dengue infection, therefore, we systematically reviewed studies describing renal disorders in dengue infection, with emphasis on Acute Kidney Injury (AKI). The purpose of current review is to underscore clinicians’attention to this neglected intricacy of DVI. It suggests that dengue induced renal involvements vary from glomerulonephritis, nephrotic range proteinuria and AKI. We observed great disparity in incidence of AKI among dengue patients, based upon criteria used to define AKI. AKI among dengue patients was found to be associated with significant morbidity, mortality and longer hospitalization, adding financial burden to patients and healthcare system. Additionally, we identified several predictors of AKI in dengue patients including old age, obesity, severe dengue infection and concurrent bacterial or viral infection. Direct viral injury and deposition of antigen-antibody complex in glomerulus were found to be possible causes of renal disorders in dengue infection. Prior knowledge of clinico-laboratory characteristics and risk factors with early detection of AKI by using appropriate criteria would not only reduce morbidity and mortality but also decrease burden to patients and healthcare system.
