Azathioprine immune hypersensitivity reaction is a rare adverse effect that has been reported in the literature relatively infrequently; however, the clinical presentation can often mimic sepsis [1, 2].
In the context of allergic reactions, Th1 polarization with priming of antigen-specific CD4+ T cells and CD8+ cells occurs in the background of Th1 cytokines including interleukin-2 (IL-2) and interferon-[gamma] (IFN-[gamma]), leading to recruitment and activation of eosinophils and monocytes/ macrophages that together with the primed T lymphocytes, generate a T cell-mediated delayed immune hypersensitivity reaction [1].
