Which acute phase reactants are the most decisive ones for the follow-up of COVID-19 patients?
Initial results of acute phase reactants such as C-reactive protein, alanine transaminase, lactate dehydrogenase, D-dimer, procalcitonin, serum ferritin and IL-6 on admission were used to evaluate the severity and predict the mortality. However, dynamic changes of these variables will be more precise in predicting the recovery or progression of COVID-19. Continuing or progressively increasing levels of C-reactive protein, procalcitonin, D-dimer and lactate dehydrogenase were shown to be associated with a high risk of death in severe COVID-19 patients.22,49,92
