Background:
Studies showed that lncRNA HCP5 was associated with a variety of autoimmune diseases. This study evaluated the diagnostic potential of lncRNA HCP5 for immune thrombocytopenia (ITP) and its prognostic value in predicting disease progression, offering clinical application insights.
Research Design And Methods:
This study analyzed 40 ITP patients and 40 controls. qRT-PCR measured lncRNA HCP5 expression, while flow cytometry quantified Th17/Treg percentages. Pearson correlation assessed HCP5-clinical feature relationships. ROC analysis determined diagnostic potential, and Kaplan-Meier/Cox regression evaluated prognostic significance.
Results:
ITP patients showed decreased platelet counts, Treg percentages, and lncRNA HCP5 levels, but increased Th17%s versus controls. LncRNA HCP5 showed positive correlation with platelets/Tregs but negative with Th17 cells, and was associated with ITP bleeding severity. With a cutoff of 0.825, lncRNA HCP5 had an AUC of 0.979 for ITP diagnosis, sensitivity of 0.900, and specificity of 0.925. Kaplan-Meier analysis showed increased 1-year recurrence with low HCP5 expression, and Cox regression confirmed it as a poor prognostic factor.
Conclusions:
LncRNA HCP5 expression correlated significantly with Treg cell percentage, Th17 cell percentage, and the degree of bleeding in ITP patients. LncRNA HCP5 has high diagnostic and prognostic value for ITP.
