Furthermore, given derangements in the metabolic proteins and enzymatic biomarkers, levels of C-reactive protein (CRP), alanine aminotransferase (ALT), γ-glutamyl transferase (GGT), lactic dehydrogenase (LDH), and procalcitonin (PCT) were significantly lower in delta variant (unvaccinated) patients than those in wild-type infection, whereas some of the others remained comparable or became much higher such as alkaline phosphatase (ALP), creatinine, and creatine phosphokinase (CPK). This evidence concerns the gene PIK3C2A and infection.
