Bone marrow suppression

[1] Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine.

This condition can rapidly lead to life-threatening infection, as the body cannot produce leukocytes in response to invading bacteria and viruses, as well as leading to anaemia due to a lack of red blood cells and spontaneous severe bleeding due to deficiency of platelets.

Parvovirus B19 inhibits erythropoiesis by lytically infecting RBC precursors in the bone marrow and is associated with a number of different diseases ranging from benign to severe.

[6] Bone marrow suppression due to azathioprine can be treated by changing to another medication such as mycophenolate mofetil (for organ transplants) or other disease-modifying drugs in rheumatoid arthritis or Crohn's disease.

[10] Trilaciclib (COSELA), a CDK4/6 inhibitor, is administered before chemotherapy in small cell lung cancer to control chemotherapy-induced myelosuppression.
