Objective: Denguefeveris one of the important tropical disease of public health significance caused by flavivirus. It is a major cause of morbidity and mortality worldwide. Identification of factors associated with severity of dengue can improve the prognosis of the disease.This study tried toassess the factors associated with severity of dengue.Methods: A record based study was conducted in a tertiary care hospital setting in southern India. A total of 550 case files were reviewed to ascertain demographic, clinical and laboratory parameters among confirmed cases of dengue. The severity of dengue was categorized using WHO 2009 classification.Results: Of 550 records reviewed, 449 (81.6%) were classified as non-severe dengue and 101 (18.4%) as severe dengue. Factors associated with severe dengue on univariate analysis were: gender, backache, skin rash, nausea and vomiting, abdominal distension, haemorrhage, breathlessness, oliguria, hepatomegaly, splenomegaly, ascites, leukopenia, hypoproteinemia, and elevated serum alanine transaminase (ALT) >63 IU/L.On multivariate analysis,haemorrhage (OR=11.75, 95%; CI=6.38-21.62), oliguria (OR=4.01, 95%; CI=1.32-12.15), ascites (OR=2.68, 95%; CI=1.19-6.01), ALT>63 IU/L (OR=1.77, 95%; CI=1.01-3.1) and hypoproteinemia (OR=5.57, 95%; CI=2.82-10.98) were found to have significant association with the development of severe dengue.Conclusion: This study indicates thatwhen dengue patients present with bleeding episodes, ascites, oliguria,raised ALT and low serum protein levels, clinicians should be alert to the appearance of severe complications. Early identification of these factors will help clinicians to recognise the severity of dengue illness and enable them to implement appropriate interventions.
