ABSTRACT
Background Dengue infections caused by the four antigenically distinct dengue virus serotypes (DENV1, DENV2, DENV3, DENV4) of the family Flaviviridae are the most major arboviral diseases in humans in terms of geographic spread, morbidity, and mortality. Objective: The study was conducted to assess serum lactate in cases of dengue and correlate it with severity in dengue infection. Methodology: A prospective observational study was carried out among indoor patients admitted to the general medicine department of the tertiary care hospital SMIMER Surat. The study's duration was 15 to 18 months. Result: our study found out of total 154 cases; majority of cases were belonged from 83(53.90%) cases were from less than 30 years. male was contributed 96 (62.34%), majority of cases had duration of fever 39(25.32%), 66 (42.66%) case had high LDH, comparison of serum lactate dehydrogenase with severity of dengue mean lactate dehydrogenase of dengue without severity was mean was 148.45 and SD 11.81, while in severe dengue mean serum lactate dehydrogenase 388.23 and SD 99.47 with p value 0.001 which was statically significant. Conclusion According to this study, it is preferable to monitor serial lactate levels as opposed to using a single lactate number.
