Metagenomic next-generation sequencing for detection of pathogens in children with hematological diseases complicated with infection
Objective
Infection is one of the most common causes of death in children with hematological diseases. Here, we aim to investigate the value of metagenomic next-generation sequencing (mNGS) in the detection of causative pathogens in children with hematological diseases.
Methods
In this retrospective study, specimens from children with hematological diseases, who were admitted to Sun Yat-Sen University between June 2019 and September 2021, were collected for culture and mNGS.
Results
A total of 67 pediatric patients were enrolled, and 96 specimens were collected. The positive rate of mNGS was significantly higher than that of culture (57.2% vs 12.5%, P < 0.01). The concordance (90.9%, 10/11) between the positive results of the two methods was high. mNGS detected more cases with Pneumocystis jeroveci, Aspergillus flavus, viruses, and some rare pathogens than culture. Mixed infections were detected by mNGS in 16 cases. Clinical anti-infective treatment was adjusted according to the results of mNGS, the conditions of most patients improved.
Conclusion
Compared to culture, mNGS shows great advantages in diagnosing bacterial, fungal, viral, and mixed infections in children with hematologic diseases, positively impacting clinical care. mNGS can be used as a complement to culture for pathogen detection.
