Conclusion
This study revealed that HCQ was associated with increased platelet
counts in children with chronic ITP. We did not find interaction effect
of ANA level on the treatment efficacy of HCQ. Meanwhile, some side
effects were also observed, indicating that weighting the advantages and
disadvantages when planning to introduce it are of importance. Before
using HCQ as a proposed therapy for children with ITP, it is necessary
to identify its appropriate population and explore drug monitoring
methods.
