CRP and alkaline phosphatase measurement: The patients with AP presented a longer hospital stay, necessitated a longer antiviral and corticoid treatment, showed a higher plasmatic glucose, a more pronounced inflammatory syndrome (illustrated by increases in CRP, ESR, and fibrinogen), cytolytic syndrome (higher serum LDH and AST), higher leukocytes and neutrophils values, mild increases in platelets, D-Dimers, potassium, and a more severe lung involvement demonstrated by higher percentages of mixed and interstitial lung lesions (Table 3).
