Case 116 – Update 3!

Thank you for everyone’s contributions.

Due to his history of renal disease and renal transplant it is important that we consider these as potential secondary causes of polycythaemia. However, taking a thorough history and review of previous blood results has identified that he has been polycythaemic for the past 3 years which preceded his renal issues. It is important to note that we can’t exclude post transplant polycythaemia as a contributing cause. There was nil else on his history which was indicative of another secondary cause.

We now have the outstanding blood results that you have all requested:

Erythropoietin: Low

JAK2 V617F: Present


  1. What is the main cause of his polycythaemia and how what would your management be for this patient?
  2. What is the management of post-transplant polycythaemia and would you institute it in this case?
