In order to provide non-invasive, reliable and sensitive laboratory parameters
for the diagnosis of primary biliary cirrhosis (PBC), metabolic technology of
ultraperformance liquid chromatography coupled with quadrupole-time-of-flight
mass spectrometry (UPLC/Q-TOF MS) was used to compare small molecule metabolites
in blood and urine from patients with PBC and healthy controls. We then screened
for bio-markers in the blood and urine of the patients with PBC. Data were
processed by Bruker ProfileAnalysis metabonomic software and imported to SIMCA-P
software, which utilized principal component analysis (PCA) to create models of
patients with PBC and healthy controls. In total, 18 urinary markers were found
and the levels of 11 of these urinary markers were elevated in the patients with
PBC, whereas the levels of the remaining 7 markers were lower in the PBC group
compared to the control group. We also identified 20 blood-based biomarkers in
the patients with PBC and the levels of 9 of these markers were higher in the PBC
group, whereas the levels of the remaining 11 markers were lower in the patients
with PBC compared to the controls. Among these biomarkers, the levels of bile
acids increased with the progression of PBC, while the levels of carnitines, such
as propionyl carnitine and butyryl carnitine, decreased with the progression of
PBC. In conclusion, the findings of the present study suggest that the
circulating levels of bile acids and carnitine are differentially altered in
patients with PBC.
