One case report of aspergillus lumbar spine infection diagnosed by metagenomic next-generation sequencing after renal transplantation and literature review / 中华器官移植杂志

ABSTRACT

Objective:To explore the application and value of metagenomic next-generation sequencing (mNGS) in refractory infection after organ transplantation.Methods:A case report discussed about a patient with lumbar spine infection after kidney transplantation and the relevant literature was reviewed. The recipient was a 63-year-old man with low back pain after kidney transplantation. Lumbar spine magnetic resonance imaging showed lumbar spine infection. Multiple operations plus antibacterial and antituberculosis treatments were ineffective. Before and after treatment, numerous tests of traditional pathogenic microorganisms failed to detect any positive bacteria.Results:The detection of lumbar secretion by mNGS suggested aspergillus infection. The symptoms improved after dosing of voriconazole.Conclusions:The incidence of fungal infection of lumbar spine is low. The imaging manifestations are non-typical so that it is easy to misdiagnose. mNGS helps to timely diagnose and guide treatment. With a review of the literature, mNGS has some application value for some difficult and rare infectious diseases.
