Impact of age to ferritin and neutrophil-lymphocyte ratio as biomarkers for intensive care requirement and mortality risk in COVID-19 patients in Makassar, Indonesia.
Inflammation plays a substantial role in COVID-19 pathophysiology. Ferritin and neutrophil-lymphocyte ratio (NLR) are significant prognostic biomarkers used in COVID-19 patients, although they are affected by other factors such as comorbidities and age. Aging changes the immune system through immunosenescence and inflammaging; however, there are limited number of studies evaluating its effect on ferritin and NLR as part of the complete assessment for intensive care requirement and mortality risk. ⋯ Age significantly multiplied clinical endpoints in low-risk group patients but not in high-risk group patients. The combination of ferritin and NLR had a better predictive value for intensive care requirement and mortality risk. However, age strongly affects clinical outcome in low-risk groups of both ferritin and NLR groups; hence, it should be considered as an early predictive factor of COVID-19 disease progression.
