Refractory severe idiopathic thrombocytopenia and treatment challenges.

Unlabelled: Refractory idiopathic thrombocytopenia (ITP) is a disease that does not respond to or relapses after splenectomy, requires treatment to reduce the risk of clinically significant bleeding, and is a challenging case to treat.

Presentation Of The Case: A 39-year-old male with a history of chronic ITP presented with a platelet count of 1000/µl and prostatitis. He was started on Ciprofloxacin and started intravenous immunoglobulin along with intravenous methylprednisolone. Then Rituximab was started on day fourth. Since his platelet remained 0/µl, Mycophenolate mofetil (Cellcept) was started on day 14th. Next, a dose of Romiplostim on day 19th was given. Eltrombopag (Promacta) and Tavlesse were started on day 23th and platelets rose to 96×10/µl on day 26th and then 418×10/µl.

Discussion: Normally, refractory ITP patients who do not respond to first-line treatments require a combination therapy of one to two medicines of the second line, like thrombopoietin receptor agonists. However, this patient's thrombocytopenia neither responded to first-line treatment nor second-line treatment with Promacta/Romiplostin plus immunosuppressives or Tavlesse.

Conclusion: Refractory ITP, who has not responded to first-line and second-line treatments, requires treatment with a combination of all first-line and second-line treatments. Furthermore, Promacta, Tavlesse, and Romiplostim have a big role to play in helping the patient.
