Abstract
Background
Zhenzhu Tongluo pills (ZZTL) have been utilized for the treatment of neurobrucellosis (NB) in the Inner Mongolia region of China. However, the specific mechanism underlying the neuroprotective effects of ZZTL in NB remains insufficiently explored. Therefore, this study aimed to analyze the metabolite profiles across different groups to identify potential biomarkers for the diagnosis and treatment of NB.
Methods
LC–MS analysis was used to screen differential metabolites in cerebrospinal fluid (CSF) samples from control subjects, NB patients, and NB patients undergoing ZZTL therapy.
Results
We identified 225 common metabolites across two comparison groups (NB vs. control group and NB + ZZTL vs. NB group). Among these metabolites, 138 were downregulated, and 87 were upregulated in the NB group compared to the control group, while the levels of these metabolites were reversed by ZZTL therapy. Creatinine exhibited the highest VIP score in both comparison groups, with elevated levels observed in CSF samples from NB patients compared to controls; however, its levels were reduced following ZZTL therapy. Additionally, hypoxanthine and uric acids levels were also increased in CSF samples from NB patients, indicating dysregulation of purine metabolism in NB; however, these changes were reversed by ZZTL. Furthermore, pantothenic acid (vitamin B5) and niacinamide (vitamin B3) levels were decreased in CSF samples from NB patients, suggesting a potential link between NB and vitamin B3 and B5 deficiency; however, these changes were reversed by ZZTL.
Conclusion
Collectively, CSF metabolomics may effectively differentiate NB patients from control subjects, providing valuable insights for NB diagnosis and treatment.
期刊介绍:
Rapid Communications in Mass Spectrometry is a journal whose aim is the rapid publication of original research results and ideas on all aspects of the science of gas-phase ions; it covers all the associated scientific disciplines. There is no formal limit on paper length ("rapid" is not synonymous with "brief"), but papers should be of a length that is commensurate with the importance and complexity of the results being reported. Contributions may be theoretical or practical in nature; they may deal with methods, techniques and applications, or with the interpretation of results; they may cover any area in science that depends directly on measurements made upon gaseous ions or that is associated with such measurements.
