Research Summary

Clinical and Laboratory Diagnosis of Heparin-Induced Thrombocytopenia (HIT) in Children: a Prospective Pilot Study

1. To describe an inception cohort consisting of pediatric patients undergoing cardio-pulmonary bypass surgery (CPB) prospectively recruited upon their admission to The Hospital for Sick Children (Sickkids®). Subjects will be investigated prospectively for heparin-induced thrombocytopenia (HIT) by both heparin-PF4 (H-PF4) antibodies detected by enzyme immunoassays (ELISA) and by a confirmatory serotonin-release assay (SRA).

2. To compare the specificities and sensitivities of two ELISA screening assays in children tested for HIT regarding the detection of H-PF4 antibodies; the former laboratory method will be using 3 immunoglobulin (Ig) subclasses (IgA, IgM, and IgG); the latter will be testing only the IgG subclass.

3. To evaluate the potential use of clinical predictive tools previously develop for the investigation of HIT in adults in a pediatric population (i.e., the 4T score and the score developed by Lillo-Le et al for patients post-CPB)

4. To stratify the HIT assay results by patient type (i.e., use of the PELOD clinical severity score), pre-test risk assessment by two previously described clinical scoring system, and correlate these with their respective clinical-laboratory outcomes (incidence of thrombocytopenia, thrombosis, changes in anticoagulation therapy, and mortality).

5. The compare the clinical (thrombosis and mortality rates) and laboratory (thrombocytopenia) outcomes of pediatric patients undergoing CPB with the results of H-PF4 antibodies detected only by ELISA methods.
