Successful treatment of Henoch-Schönlein purpura-associated hematochezia in a child with hemophilia A: a case report.

A child with hemophilia A developed Henoch-Schönlein purpura (HSP) while receiving coagulation factor VIII replacement therapy.

• The patient was an 8-year-old male with pre-existing hemophilia A.
• HSP was diagnosed during hospitalization while the patient was already on factor VIII replacement therapy.
• There is described to be no causal relationship between hemophilia A and HSP.

Hematochezia developed 6 days after the diagnosis of HSP in this patient with hemophilia A.

• Hematochezia onset occurred 6 days following the HSP diagnosis.
• The hematochezia was attributed to HSP rather than hemophilia A, though hemophilia could not be ignored during treatment.
• Both diseases independently increase the risk of bleeding through different mechanisms.

The HSP-associated hematochezia in the child with hemophilia A was successfully treated with a combination regimen.

• Treatment consisted of coagulation factor VIII replacement, methylprednisolone, and hemostatic drugs.
• The combination approach was necessary because both conditions — HSP and hemophilia A — contributed to bleeding risk.
• The case adds to knowledge about managing HSP-associated hematochezia in the context of a concurrent bleeding disorder.
