Hydroxyurea helps convert the normal hemoglobin to fetal hemoglobin, which is a special type of hemoglobin that is immune to sickling. It may also result in the overproduction of white blood cells and platelets..  |  While incidences of thrombosis and acute myeloid leukemia were stable over time, mortality and myelofibrosis varied depending on follow-up duration.

Hydroxyurea is commonly used in these disorders for its cytoreductive properties; however, the effect of this treatment on proteinuria or kidney function remains unclear in cases of myeloproliferative disorder–associated FSGS. To date, the median duration response in those treated with the JAK inhibitor has still not been reached, according to updated data presented at the 2017 ASH annual meeting.
