The Immature Reticulocyte Fraction As an Aid in the Diagnosis and Prognosis of Parvovirus B19 Infection in Sickle Cell Disease

ConclusionsOur data confirms that amongst a cohort of complicated patients with SCD and other causes for reticulocytopenia, the IRF is highly specific for detecting the severe aplasia caused by B19 infection in this group. This additional data may be useful in better triaging patients with SCD and reticulocytopenia and potentially in improving utilization of the more expensive B19 diagnostic testing. Furthermore our study suggests that an increasing IRF predicts reticulocyte recovery in reticulocytopenic patients with SCD and could have utility in clinical decision making such as whether to transfuse packed red blood cells or whether they can be safely discharged from the hospital.DisclosuresLambert: Amgen: Membership on an entity's Board of Directors or advisory committees; Sysmex: Consultancy; Bayer: Membership on an entity's Board of Directors or advisory committees; Novartis: Membership on an entity's Board of Directors or advisory committees; Educational Concepts in Medicine: Consultancy; Summus: Consultancy; Rigel: Consultancy; Shionogi: Consultancy; CSL: Consultancy.
