SUMMARY

Anand Padmanabhan, M.B.B.S., Ph.D., has translational research interests in platelet immunology, with a focus on heparin-induced thrombocytopenia (HIT), vaccine-induced immune thrombotic thrombocytopenia (VITT), and thrombosis and thrombocytopenia syndrome (TTS). He also has clinical and research interests in transfusion medicine, including evidence-based use of apheresis, hematologic cell collections and optimization of vascular access to facilitate apheresis.

Heparin-induced thrombocytopenia causes more than five deaths each day in the U.S. Timely and accurate diagnosis can be a challenge, as current testing algorithms frequently lead to both overdiagnosis and delayed diagnosis. Dr. Padmanabhan's research seeks to significantly change the testing paradigm so that early and accurate diagnosis of heparin-induced thrombocytopenia can facilitate timely, appropriate therapy. In addition, he studies novel ways to treat HIT and other anti-PF4 antibody mediated syndromes such as VITT and TTS.

Focus areas

  • Epidemiology. Clarifying heparin-induced thrombocytopenia incidence in various patient populations
  • Pathophysiology. Investigating the biochemical basis of the difference between pathogenic and benign heparin-induced thrombocytopenia antibodies, and evaluating the pathophysiology of antibody-mediated platelet activation
  • Diagnosis. Developing novel technologies and processes to facilitate early and accurate diagnosis of HIT, VITT and TTS
  • Treatment. Investigating new treatments for patients with HIT and other anti-PF4 antibody-mediated syndromes, especially for patients with severe presentations

Significance to patient care

Dr. Padmanabhan's research has led to better ways of diagnosing heparin-induced thrombocytopenia, a disorder in which early diagnosis is critical for appropriate management. He led a research group that first documented the utility of PF4-treated platelets for the detection of pathogenic anti-PF4 antibodies, resulting in the development of a novel assay (PF4-dependent P-selectin Expression Assay).

Dr. Padmanabhan's research has also guided new ways to manage severe heparin-induced thrombocytopenia that is resistant to standard therapies. A better understanding of HIT, VITT and TTS pathophysiology is important in making further improvements in prevention, diagnosis and treatment.

Dr. Padmanabhan led the evidence-based writing group of the American Society for Apheresis that discusses the use of apheresis in numerous disease states. This is of relevance to patients with many organ system diseases and disorders amenable to apheresis therapies.
