CRP and acute kidney injury: White cell count (12.6 x109/L), C-reactive protein (257 mg/L), and lactate (2.9 mmol/L) were elevated suggesting an infective or inflammatory process, and the renal profile revealed a stage three acute kidney injury (AKI; creatinine 456 μmol/L), hyperosmolar hyponatremia (serum sodium 106 mmol/L; 127 mmol/L when corrected for hyperglycemia), and hyperkalemia (potassium 6.2 mmol/L). Liver function tests (LFTs) were unremarkable, but lipase was elevated (659 IU/L).
