Blood exams reported only hyponatremia (132 mEq/L, range 136–146 mEq/L), slightly high levels of C-reactive protein (CRP, 2 mg/dL, range 0–0.7 mg/dL), alteration of D-dimer (3608 ng/mL, range 0–500 ng/mL), significant elevation of procalcitonin level (PCT, 51 microg/L, normal range < 0.5 microg/L) and normal lactates value (1.2 mmol/L) (Table 1). This evidence concerns the gene CRP and Hyponatremia.
