Ping Zhang, Yanan Cai, Fei Ge, Zunmin Zhu, Kai Sun Department of Hematology, Henan Provincial People’s Hospital, People’s Hospital of Zhengzhou University, Zhengzhou, People’s Republic of ChinaCorrespondence: Kai Sun, Department of Hematology, Henan Provincial People’s Hospital, People’s Hospital of Zhengzhou University, #7 Weiwu Road, Zhengzhou, People’s Republic of China, Email [email protected]: This study aims to investigate the incidence, clinical characteristics, and prognosis of thrombosis in Chinese patients with immune thrombocytopenia (ITP).Methods: This was a single-center, retrospective study of adult patients with ITP at the Henan Provincial People’s Hospital from January 2018 to June 2023.Results: A total of 3216 adult patients with primary ITP were included in the study period, with 25 (0.93%) having thrombotic events. The average age of 25 patients with thrombosis is 62.76± 12.79 years, including 11 males and 14 females. In addition, among the 25 thrombotic events, 19 cases were arterial thrombosis (AT), and 6 cases were venous thrombosis (VT). The incidence of AT is higher than that of VT (P=0.009). There was no obvious difference in clinical characteristics between the two groups. The median platelet count at the time of thrombosis in 25 patients was 35 (23, 52) × 109/L. At the onset of thrombosis, 23 patients (92.0%) had a low PLT (< 100× 109/L). One patient with ischemic stroke died in the hospital due to severe infection.Conclusion: ITP may be considered a bleeding disorder with a high risk of thrombosis, and AT is more common than VT in the Chinese population.Keywords: immune thrombocytopenia, arterial thrombosis, venous thrombosis, platelet, hemorrhagic disease
