Description
Summary:Heparin-induced thrombocytopenia (HIT), a rare complication of heparin therapy, presents with thrombocytopenia. It leads to paradoxical thromboembolism and has high mortality if untreated. It is less recognized, especially in hemodialysis (HD) patients who are frequently exposed to heparin during dialysis because patients with renal failure may have many other causes of thrombocytopenia. We describe the clinical presentation, diagnosis, and treatment of five cases of confirmed HIT in hemodialysis (HD) patients at our center. The initial suspicion was made based on a high 4T score and positive gel card test followed by confirmation using the functional assay with heparin-induced platelet aggregation. These patients were treated according to the recent American Society of Hematology guidelines 2018 for HIT.
