Sargramostim for Myeloid Dendritic Cell Deficiency

The overall objective of this project is to study the ability of sargramostim to enhance mDC level and function, including subsequent stimulation of T cell responses, in various human subjects with demonstrated myeloid dendritic cell (mDC) and T cell deficiency. Single center nonrandomized trial with an interrupted time series design involving measures on blood samples from three separate populations before and after administration of sargramostim. The objective is to determine the safety and dose response of sargramostim administration in healthy participants and in patients with chronic kidney disease (CKD) and kidney transplants. Additionally to determine whether reversal of mDC/T cell deficiency by sargramostim results in augmented T cell responses in these three groups.
