Context: Kalaburgi is an endemic area of dengue virus infection. Aims: To study levels and to establish correlation between severity of DVI with serum electrolyte and troponin T. Design: Hospital based prospective study. Methods and materialss: Children between 1 month t-18 years with ELISA IgM positive dengue cases. Statistical analysis used: Data was entered in Microsoft excel sheet and SPSS 20.0 software was used for analysis. Results: Mean age group was 1-5 years (31.9%). 55.55% were male and 44.44% were female. 30 (41.7%) were DF, 14 (19.4%) were DHF and 28 (38.9%) were among DSS group. Fever was the most consistent compliant. Ascites (26.4%), pleural effusion (25%) and cold peripheries (25%) were most common signs. Mean serum sodium was 134.8mEq/L. Mean serum potassium was 3.73mEq/L. Elevated cTnT levels were present in 27.7% cases. Mortality rate was 17.8%. Conclusion: Mild hyponatremia and hypokalemia were common electrolyte disturbances. There was statistically very significant difference in mean serum sodium and serum potassium levels between DF and DSS (p value<0.001), with decreasing serum sodium levels there was an increasingly associated complications. Level of cTnT was highest among DSS followed by DHF and it was within the normal limits among DF cases. There were highest number of mortality among DSS group followed by DHF group and no mortality among DF group.
