Abstract
In both the earlier waves of COVID-19 variants, severe and fatal respiratory disease like acute respiratory distress syndrome (ARDS) became more fatal in population with comorbid conditions. Therefore, early identication of severe COVID-19 is very important for individual's precise management, including antiviral, oxygen support and intensive care unit (ICU) management. First case of COVID-19 got reported in the medical record of India on 30th January 2020 in a student who had returned from Wuhan, China. In 2020 and 2021 it was found that individuals with increased serum ferritin and LDH level landed up with severe and very severe COVID-19 if not treated timely and correctly. So correlation between S. Ferritin and LDH in 1st and 2nd wave was required to evaluate the condition of patients who remained admitted in critical care unit with or without comorbid conditions. This is hospital based cross- sectional observational study on 50-50 (total-100) critically ill patients admitted during 2020 and 2021 respectively. We found that In 2020 during the 1st wave serum LDH and serum Ferritin levels were signicantly high with the mean value of 481.65 U/L and 532.56 ng/ml respectively and in 2021 during 2nd wave serum LDH and serum Ferritin levels were again signicantly high with the mean value of 488.43 U/L and 667.27 ng/ml respectively. In 2020 patients with comorbid conditions showed S. LDH and Ferritin mean value of 543.47 U/L and 582.63 ng/ml respectively and in 2021 during 2nd wave it showed S.LDH and Ferritin levels mean value of 672.72 U/L and 727.38 ng/ml respectively. Both inammatory markers were signicantly more increased in the critically ill patients who presented with co-morbidities. This study will provide improved condence to health workers working in remote areas and COVID-19 hospitals in predicting transfer of COVID-19 patients to tertiary care hospitals for critical care management at the earliest.
