Case report: Metagenomics next-generation sequencing in the diagnosis of septic shock due to Fusobacterium necrophorum in a 6-year-old child

Abstract

Fusobacterium necrophorum (F. necrophorum) infection is rare in pediatrics. In addition, the detection time of F. necrophorum by blood culture is long, and the positive rate is low. Infection with F. necrophorum bacilli usually follows rapid disease progression, resulting in high mortality. In previous reports of F. necrophorum-related cases, the most dangerous moment of the disease occurred after the appearance of Lemierre's syndrome. We report an atypical case of a 6-year-old female patient who developed septic shock within 24 h of admission due to F. necrophorum infection in the absence of Lemierre's syndrome. F. necrophorum was identified in a blood sample by metagenomics next-generation sequencing (mNGS) but not by standard blood culture. The patient was finally cured and discharged after receiving timely and effective targeted anti-infection treatment. In the present case study, it was observed that the heightened virulence and invasiveness of F. necrophorum contribute significantly to its role as a primary pathogen in pediatric septic shock. This can precipitate hemodynamic instability and multiple organ failure, even in the absence of Lemierre's syndrome. The use of mNGS can deeply and rapidly identify infectious pathogens, guide the use of targeted antibiotics, and greatly improve the survival rate of patients.

Keywords: Fusobacterium necrophorum; case report; children; metagenomics next-generation sequencing; sepsis.

Chest CT in the clinical course of the patient: (A) Multiple small patchy hyperdense shadows and nodular shadows in both lungs (the day of admission). (B) The laryngeal–pharyngeal area was slightly narrow (red arrow, the day of admission). (C) Patchy hyperdense shadows were absorbed, and nodule shadows were significantly reduced (the 14th day of admission). (D) No evidence of internal jugular vein thrombophlebitis or abscess, the morphology of the laryngeal pharyngeal area returned to normal (red arrow, the 14th day of admission).

In the Others section, the total number of sequences was 2,642 reads and the percent was 99.21%, including Prevotella, Acinetobacter, Stenotrophomonas, and Neisseria (the human reads were removed).
