Factors Associated with Remission in Children Presenting with Isolated Thrombocytopenia: A Retrospective Study at Vachira Phuket Hospital
Keywords:
Isolated thrombocytopenia, Remission, Children, Associated factorsAbstract
Background: Most children with isolated thrombocytopenia achieve remission within 12 months. However, approximately 20–25% have persistent thrombocytopenia and progress to chronic immune thrombocytopenia (ITP). Data on factors associated with remission among Thai pediatric patients remain limited.
Objective: To identify factors associated with remission in children younger than 15 years who were initially diagnosed with isolated thrombocytopenia at Vachira Phuket Hospital.
Methods: This retrospective cohort study reviewed the medical records of 90 children younger than 15 years who were initially diagnosed with isolated thrombocytopenia at Vachira Phuket Hospital between 2020 and 2025. Demographic, clinical, and laboratory data were collected. Descriptive statistics were used to summarize the data. Factors associated with remission were analyzed using univariable and multivariable logistic regression analyses. Results are presented as odds ratios (ORs) with 95% confidence intervals (95% CIs).
Results: A total of 90 patients were included. Fifty-four patients (60.0%) achieved remission within 3 months after diagnosis, and an additional 9 patients (10.0%) achieved remission between 3 and 12 months after diagnosis. Twenty-seven patients (30.0%) had persistent thrombocytopenia beyond 12 months. However, two patients with chronic ITP subsequently achieved remission after 12 months. Overall, 65 patients (72.2%) achieved remission, while 25 patients (27.8%) did not achieve remission. Multivariable logistic regression analysis showed that male sex was independently associated with remission (adjusted OR 3.76, 95% CI 1.23–11.46; p=0.020)
Conclusion: Male sex was independently associated with remission in children initially presenting with isolated thrombocytopenia.
