“…Immunosuppressive agents, antihypertensive agents (angiotensin-converting enzyme inhibitors, e.g., angiotensin-converting enzyme; angiotensin-receptor blockers, e.g., ARB), iron deficiency, hemolysis, and malignant tumors also result in anemia. Among infections, parvovirus B19 causes post-transplantation pure red cell aplasia [256]. Among immunosuppressive agents, inhibitors of nucleic acid synthesis (e.g., mycophenolate mofetil, azathioprine, mizoribine) are particular causes of bone marrow suppression throughout the post-transplant course [247].…”
