ABSTRACT

Objective To analyze the clinical characteristics and perinatal outcomes of listeriosis during pregnancy. Methods From July 2010 to April 2017, 70 131 women delivered in West China Second University Hospital.Nineteen cases were confirmed as listeriosis.The clinical symptoms,laboratory results,pathogens,placenta pathology and perinatal outcomes were analyzed retrospectively. Results The median age of the 19 cases was 29.7 (19.0-42.0) years old. The median time before diagnosis was 4.8 (0.5-19.0) days. The main clinical symptoms at first visits were high fever (17/19), increased white blood cells (18/19), abdominal pain (12/19). Listeria was found in samples of mother′s blood (11/19), vaginal secretions(15/19),placenta(1/19),neonatal blood(4/19),neonatal phlegm(5/19)and neonatal ear secretions (1/19),respectively.Inflammation of placenta was identified in all 19 cases.Among the 19 cases,1 was gradeⅠ chorioamnionitis,4 was grade Ⅱ,5 was grade Ⅲand 9 was grade Ⅵ. Only 4 newborn survived after therapy,and others suffered perinatal death,including 8 cases of intrauterine death,3 cases of miscarriage and 6 cases of treatment failure. Conclusions Listeriosis has characteristics of acute onset, quick development and high morbidity during pregnancy. The empiric use of antibiotics might not cover listeria. The understanding of listeriosis should be improved.
