Clinical features of capillary bronchitis related to bordetella pertussis

Abstract

Pertussis infection can mimick the clinical manifestations of lower airway infection, while the symptoms and signs in some cases are like Bronchiolitis. The paper carried out retrospective analysis of infant pertussis bordetella infected cases admitted by the Respiratory Dept. of Tianjin Children's Hospital for “capillary bronchitis” from Sept. 2015 to Feb. 2016. It analyzed its clinical features, radiological features, laboratory characteristics and outcome through comparing the capillary bronchitis cases induced by the non-bordetella pertussis. 26 cases of patients infected with bordetella pertussis were included in the group, 15 male patients and 11 female patients, aging from 40 days to 11 months. Comparing with non-pertussis infected cases, the capillary bronchitis induced by pertussis presents spasmodic cough, vomiting after cough, apnea suspension and lymphocythemia and obvious prolong of LOS. However the clinical symptom score is decreased and the duration of breathing is shorter. The follow-up visit detects that the recurrent number of respiratory symptoms of pertussis infected children is higher than that of non-pertussis infected children. The clinical symptoms of patients with capillary bronchitis infected by bordetella pertussis are not typical and are susceptible to be ignored. The duration of respiratory symptoms is longer and susceptible for recurrence.
