Values are mean ± SD (range). ALT = alanine aminotransferase; CRP = C-reactive protein; ESR = erythrocyte sedimentation rate. Reference ranges: leukocytes = 3.0–10.0 × 103/µL; neutrophils = 2.0–7.5 × 103/µL; lymphocytes = 1.5–4.0 × 103/µL; hemoglobin = 11.5–15.5 g/dL; bilirubin = 0–20.0 mg/dL; ALT = 10–35 IU/L; albumin = 34–50 g/L; sodium = 135–145 mmol/L; CRP = 0–5.0 mg/L; ESR = 1–20 mm/hr.
