Introduction: 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.
