Clinical features, management, and prognosis of Bacillus cereus sepsis in premature neonates.

This study aimed to investigate the clinical characteristics, management and prognosis of Bacillus cereus sepsis in premature neonates. The clinical information of 8 premature neonates with B cereus sepsis who were treated in Shanghai Children Hospital from January 2015 to December 2019 was retrospectively collected from the medical records and analyzed. The neurodevelopment related conditions were collected at follow up visits at corrected age of 6 months and 12 months. Five patients developed meningitis, and cerebral magnetic resonance image showed abnormal in 5 patients. After treatment with meropenem and vancomycin, 1 patient died, and 7 patients survived and were smoothly discharged. At follow up visits, 1 patient was diagnosed with hydrocephalus and showed severely delayed neurodevelopment, 2 patients had mild delayed neurodevelopment, and the neurodevelopment was basically normal in remaining 4 patients. B cereus infection can cause severe complications of central nervous system, and affect neurodevelopmental outcome. Antibiotic treatment with meropenem and vancomycin is proven to be effective. Refreshing the central catheters is helpful for the prevention of B cereus sepsis and cerebral magnetic resonance image may be employed for the prognosis assessment.
