Objective To examine the serum levels of degraded monosaccharides in children with Henoch-Sch?nlein purpura (HSP) and to study the clinical significance of degraded monosaccharides in HSP. Methods A prospective analysis was performed on 132 children who were diagnosed with HSP from September 2019 to January 2022, and 132 healthy children were enrolled as the control group. High-performance liquid chromatography was used to determine the content of degraded monosaccharides in serum in both groups. The receiver operating characteristic (ROC) curve was used to evaluate the efficiency of degraded monosaccharides for the diagnosis of HSP. Results Compared with the control group, the HSP group had significantly higher serum levels of mannose, glucosamine, aminogalactose, and galactose (P<0.001). The four degraded monosaccharides had an area under the ROC curve of 0.919, 0.913, 0.832, and 0.932 respectively for the diagnosis of HSP (P<0.05). Conclusions Children with HSP have higher serum levels of mannose, glucosamine, aminogalactose, and galactose than the healthy population. The levels of degraded monosaccharides may have an important value for the diagnosis of HSP.
