Risk Factors and Psychological Analysis of Chronic Immune Thrombocytopenia in Children

OBJECTIVE: To study the risk factors and psychological changes in children with chronic immune thrombocytopenia (CITP). METHODS: This was a retrospective analysis of 234 children with ITP diagnosed and treated in the Affiliated Hospital of Southwest Medical University from January 2016 to December 2018. The clinical characteristics and related laboratory factors of all patients were collected, and their impact on the chronicity of ITP was analyzed. The Eysenck Personality Questionnaire-Children’s Version (7–15 years old) is a psychological assessment of children with chronic ITP (CITP). RESULTS: Univariate analysis found that the course of the initial diagnosis (χ2 =6.879, P<0.05), the age of onset (χ2 =13.846, P<0.05) and the absolute value of the initial diagnosis of peripheral blood lymphocytes (χ2 =6.436, P<0.05) had statistical differences in the chronicity of ITP in children; a multivariate analysis of the course of the first diagnosis, the age of onset and absolute lymphocyte count (ALC) revealed that ALC is an independent factor in children’s chronic ITP (P<0.05). Compared with normal children, children with CITP had statistical significance in extraversion (t=−3.476, P<0.05); compared with newly diagnosed children, they had statistical significance in extraversion (E) and lying (L) (P<0.05); and there was no statistical difference compared with persistent children (P>0.05). CONCLUSION: The age of onset, the absolute value of lymphocytes at the initial diagnosis, and the course of the initial diagnosis are important for predicting the chronicity of ITP in children. ALC is an independent predictor; children with chronic ITP have psychological problems.
