Objective: To describe the relationship between biochemical indices and severity of Covid-19 infection in adults with Type 2 Diabetes. Research design & methods: This was a single centre retrospective study conducted in a tertiary care hospital. The data of adults with Type 2 diabetes admitted with covid 19 infection between July 2020 to January 2021 was analysed. Inflammatory markers like C-reactive protein (CRP), serum ferritin and lactate dehydrogenase (LDH) levels were correlated with severity of covid based on the extent of lung involvement in CT Chest and oxygen saturation at the time of admission. The data was compared between patients who improved and those who succumbed to the illness. Results: 411 adults with type 2 diabetes infected with novel Corona virus were included in the study. Among patients with mild lung involvement, 99.4% had mild covid, 0.6% had moderate covid and none had severe covid whereas, in patients with severe lung involvement 84% had severe covid. The mean LDH, ferritin and CRP in survivors was 318.5 IU/L, 403.8 ng/ml, and 42.7 mg/dl respectively whereas in non survivors, the values were 36.4 IU/L, 991.6 ng/ml, and 172.8 mg/dl respectively. Comparison of CT score with disease outcome revealed 88.4% survival with mild against 7.4% with severe lung involvement. Conclusion: The study highlights the importance of evaluation of inflammatory biomarkers in covid patients with type 2 diabetes, which is helpful in prognostication and identification of disease severity. This will be useful in planning the treatment for better outcomes in this population.
