Publication type: Case Reports

Minimal doses of i.v. anti-D for ITP are not exempt from the risk of intravascular hemolysis, a rare potentially severe short-lived post-infusion complication. We report here on an elderly woman with chronic pancytopenia and splenomegaly in whom bleeding manifestations ceased after i.v. anti-Rh(D) immunoglobulin minidoses replaced long-term conventional treatment for immune thrombocytopenic purpura. Anti-Rh(D) infusions, that had been well tolerated for eight years, became the main culprit in triggering of disproportionate hemolysis. In spite of in crescendo complication, the anti-Rh(D) immunoglobulin schedule was maintained for another six months. With no further treatment, the patient's health remains stable 20 months later.
