Clinical History

24 year old lady presented with complaints of:

  1. Increased duration of menstrual flow, associated with passage of clots for 13days.
  2. Bleeding gums lasting for around 5 days associated with bleeding from lips.
  3. Small red brown colored rashes present all over the body.

Immune thrombocytopenic purpura (ITP), also known as idiopathic thrombocytopenic purpura, is an immune-mediated acquired disease of adults and children characterized by transient or persistent decrease of the platelet count and, depending upon the degree of thrombocytopenia, increased risk of bleeding.[1]  Petechia, purpura, and easy bruising are expected in ITP. Less common are epistaxis, gingival bleeding, and menorrhagia. Uncommon findings are gastrointestinal (GI) bleeding, gross hematuria and intracranial hemorrhage.[2]  

The diagnosis remains one of exclusion, after other thrombocytopenic disorders are ruled out based on history, physical examination, and laboratory evaluation. [3] Diagnosis is by doing Bone marrow study Which shows Giant Megakaryocytes with increased number of Megakaryocytes[4]  

There are many treatment options.

Initial Treatment Prednisone (7-10 days) or Dexamethasone(4 days every 2 weeks for 4 cycles) +  IVIG(2 days) or Anti-D +Platelets(if bleeding)

Relapsed/Persistent ITP Rituximab(iv weekly for 4wks) or Anti-D or IVIG(iv for 2days) or Romiplostim/Eltrombopag  

Persistent/Worsening  ITP Azathioprine/danazol or Cyclosporine or chemotherapy. Splenectomy
