Oral or IV Iron: Follow up from a previous #nephjc chat

A few months ago, we discussed this trial from Rajiv Agarwal and his team from Indiana, which found increased serious adverse vents with IV iron, in CKD patients. The latest issue of Kidney International now has some interesting correspondence, with two critical letters, and a substantive reply from Rajiv Agarwal.

Among the criticism is one from Iain Macdougall and Simon Rogers, questioning the methodology - and why these results are different from the FIND-CKD trial (free PMC link), which did test a different IV iron formulation (iron carboxymaltose in FIND-CKD, iron sucrose in REVOKE), against a lower dose of oral iron. The reply from Dr Agarwal is worth reading in full, but this table highlights the details.
