Predictors of dengue-related mortality in young adults in a tertiary care centre in north India

Background: Outbreaks of dengue fever cause widespread mortality. There is a paucity of studies on predictors of morbidity and mortality in dengue. This observational study was performed to study the factors predicting adverse outcomes caused due to dengue fever thereby optimally manage the patient's to reduce mortality. Methods: The study included a 1-year retrospective and 1-year prospective period were clinical, laboratory and outcome data of patients between 18–30 years of age, having serology proven (NS1/dengue IgM) dengue fever were recorded and analysed. Results: Out of 418 patients, 404 (96.64%) recovered and 14 (3.35%) expired, resulting in a 3.35% mortality rate. Platelet count did not determine the outcome in dengue patients. The shock factor was present in 45 (11.1%) patients who recovered and 10 out of 14 patients who expired (71.4%), P value was statistically significant. Mean value of SGOT and SGPT in dengue patients who expired were 2865.43 and 1510.07 IU/L, respectively, which were significantly higher than the mean values of SGOT and SGPT in those who survived. Bleeding was present in 39 (9.7%) patients who recovered. Out of the 14 expired patients, bleeding was present in 5 (35.7%) which is statistically significant. Hence, on multivariate logistics analysis, bleeding, a higher SGOT and SGPT value and shock were found to be significant risk factors for mortality in dengue fever patients. Conclusion: Bleeding, shock and raised SGOT and SGPT levels were identified as predictors of adverse outcomes and mortality in dengue fever. Timely identification of these risk factors and active management is important to reduce dengue-related mortality.
