The analysis revealed within the Journal of Infection investigated using metagenomic next-generation sequencing (mNGS) in diagnosing bloodstream infections (BSIs) for immunocompromised hematology sufferers. Hematology sufferers are extremely inclined to BSIs, which might have extreme penalties resembling septic shock, multiple-organ failure, disseminated intravascular coagulation, and even loss of life. An correct and fast microbiological prognosis of BSI is due to this fact important for the management of the an infection.

Within the examine, performed between January 2019 and December 2020 at Tongji Hospital with the participation of BGI Genomics researcher Wenqian Zhang, peripheral blood samples had been collected from 256 immunocompromised hematology sufferers suspected of BSI, and each mNGS and standard microbiological exams (CMTs) had been carried out. BSI prognosis was confirmed in 189 out of 256 sufferers (73.8%). The detection fee of mNGS was considerably increased than that of CMTs, with mNGS figuring out 187 an infection instances and CMTs figuring out 81. Outcomes point out mNGS outperformed CMT in detecting bloodstream infections.

Micro organism had been detected in 17 sufferers (6.6%), fungi in 15 sufferers (5.9%), uncommon pathogens in 4 sufferers (1.6%), and a number of species in 55 sufferers (21.5%).

Primarily based on mNGS outcomes, viral an infection was essentially the most frequent BSI, recognized in 96 out of 256 sufferers (37.5%). The 5 most typical causative viruses had been CMV (31.3%), EBV (14.8%), HSV1 (11.7%), BK virus (11.7%) and HHV6B (9.4%).

The outcomes additionally confirmed that it was extra possible for sufferers who had undergone hematopoietic stem cell transplantation (HSCT), than those that had not, to be contaminated by BK virus and HHV6B.

Total, the examine highlights the potential of mNGS as a strong software for the speedy and correct prognosis of BSIs in immunocompromised hematology sufferers, permitting for well timed and efficient therapy.
