[Clinical Application of Two Bleeding Scoring Scales in Children with Primary Immune Thrombocytopenia].

Objective: To explore the clinical application value of the Bleeding Scoring Scales (2019 Pediatric ITP Scale) in the diagnosis and treatment of children with primary immune thrombocytopenia (ITP).

Methods: A total of 422 children with ITP were evaluated with the 2019 Pediatric ITP Scale and the 2013 ITP-BAT and their clinical data were analyzed. The correlation between the two bleeding scoring scales and disease stage, platelet count was analysed, the evaluation time, consistency of the two bleeding scoring scales was compared, and the correlation of the two methods. The changes of platelet count and the score of 2019 Pediatric ITP Scale before treatment and after treatment at 48 h and one week were analyzed to detect responsiveness of the 2019 Pediatric ITP Scale.

Results: The score of the 2019 Pediatric ITP Scale was mainly one point and two points, the corresponding bleeding was skin and mucosal bleeding.404 patients (95.7%) had bleeding manifestations, including 249 patients of skin bleeding (59.0%), 144 patients of mucosal bleeding (34.1%), and 11 patients of organ bleeding (2.6%), of which 2 patients were severe bleeding. The two bleeding scoring scales were both negatively correlated with platelet counts in children with ITP (r _s=-0.5032, r _s=-0.6084) and no correlation with the stage of pediatric ITP(P ＞0.05). The 2019 Pediatric ITP Scale had good consistency with the 2013 ITP-BAT (r _s=0.7638). The average time required for the 2019 Pediatric ITP Scale was 88.64 (40-181) seconds, which was lower than that required for the 2013 ITP-BAT 104.12 (47-285) seconds (Z =17.792, P < 0.001). The 2019 Pediatric ITP Scale can well reflect the treatment of pediatric ITP. There were statistically significant differences in platelet count before treatment and after treatment at 48 h and one week among steroid group, IVIG group and steroid combined with IVIG group ( P < 0.05). There were also statistically significant differences in the score of the 2019 Pediatric ITP Scale before treatment and after treatment at one week among the three groups ( P < 0.05).

Conclusion: The 2019 Pediatric ITP Scale has good consistency and sensitivity in clinical application, and it takes less time to complete than the 2013 ITP-BAT, this scale can be used as an effective tool for disease assessment and efficacy determination in pediatric primary immune thrombocytopenia.
