10. Plans and Follow up
Explained that we are investigating her thrombocytopenia to look for-
Either a bone marrow disorder or an immune mediated process.
As symptoms are currently bruising, she is fine to go away on her holiday to France tomorrow return and have a bone marrow test on 20th September, 2016
To be seen back in clinic in 6 weeks' time with the results of the investigations.

26. 15th November 2016

27. Admitted 1/12/16
Admitted with a platelet count of 7 and a 2 day history of epistaxis.
No recent symptoms suggestive of infection. This is on a background of newly diagnosed ITP/?lupus cytopenia
Not responding to prednisolone. She has recently been started on azathioprine (completed 2 weeks at admission).
Admitted for platelet transfusion and IV Immunoglobulins. .

28. platelet count increased to 22 after 24 hours, however, Hb had dropped further and received 1 unit of blood transfusion
platelets were hours after immunoglobulin treatment.
Initiated eltrombopag 25 mg OD

29. Haematology review 21st December 2016
No bleeding
Tapering prednisolone to 5mg
Still on AZATHIOPRINE 75mg
Eltrombopag 50mg for 2 weeks
PLT 10
Discussed option of Rituximab

30. 5th January 2016 PLT 7, HB 77 Admitted for 1st dose of Rituxamab 1gm
Had 2 units of RCC
Eltrombopag continued
AZATHIOPRINE STOPPED

31. Haematology 11th January 2016
PLT 8, HB 87, wcc 1.5, neut 0.82, lymp .70
Eltrombopag 50 mg continued
Tranexamic Acid continued

32. 19th January 2017 HB 66 , WCC* 1.8 , neut 0.87, PLT 9
Had 1 pool PLT, 2 RCC
2nd dose of RITUXMAB 1g

Nose bleeding
Transfused 1 pool platelets
Long discussion with patient
Next line o try Romoplostin (SC TPO agonist)
Response 15% may be
Wait few more weeks?
?delay response from Rituximab
Second opinion?

34. 9th February 2017

35. What next?
Ask a friend?

36. 10th February 2017 Reviewed at UCLH Under went second marrow
Repeat re staging bloods
Impression
Likely to be bone marrow failure secondary to multiple antibodies or strong immune destruction

37. Bone marrow 10thFebruaryX10

38. Bone marrow X60

39. Diagnosis?

40. Strong immune mediated peripheral destructions of all 3 cell lines

41. started MMF 1gm BD 15th February Remain pancytopenic on 7th March 2017
HB 77 WCC 1.2 Neutrophils 0.5, PLT 7
Ds DNA now negative

42. CT CNAP

43. What next? And ideas ITP most unlikely here
Peripheral destruction Secondary to multiple antibodies
But LOW HB with DAT negative
Bone marrow failure?
But her marrow was hyperactive 5 months ago
Might needs combinations of drugs?
MMF/Cyclophospahmide/Vincristine?
Pasmapheresis?
ASCT?
CT CNAP?
TCR to exclude T Cell lymphoma?
PNH screen?

44. Learning point
Immune cytopenia can be frightening for patient and the physicians
Only in refractory ITP with bleeding mortality is about 30 % yearly
Every effort should be taken to reach a diagnosis
Try combinations
Ask a friend early
