Exchange blood transfusion (ET) reportedly improves the outcomes of the patients with severe pertussis accompanied with deadly complications continued to worsen despite intensive therapeutic measures. This study assessed the medical records of 12 patients with severe pertussis requiring ET therapy who were admitted to our medical center. Of the 12 patients requiring ET therapy, 8 survived and 4 died. The independent risk factors for requiring ET therapy in infants with severe pertussis were T ≥ 38.5°C (odds ratio [OR], 11.697; 95% confidence interval [CI], 1.325-262.184; P = .046), C-reactive protein (CRP) >30 mg/L (OR, 62.393; 95% CI, 6.264-2381.773; P = .004), and WBC > 40.0 × 10 9 /L (OR, 68.509; 95% CI, 8.118-1829.695; P = .001). ET therapy worked effectively for our severe pertussis cases. When the severe pertussis patients with T ≥ 38.5°C, CRP >30 mg/L, and WBC > 40.0 × 10 9 /L, ET therapy might be taken into consideration.
