Infections associated with chemotherapy
Patients with leukemia are treated with chemotherapeutic agents, but using these carry out a series of risks, including certain types of infection. For example, treatment with doxorubicin and other anthracyclines induce cellular death in blood cells and may reduce the neutrophil count. Alkylating agents like cyclophosphamide prevents DNA repair in leukemic cells, but also in normal cells. This leads to a higher incidence of pyogenic infections (staphylococcus aureus, streptococcus infections, Klebsiella, and others).
As you can see, leukemia is a very complex disease that should not be taken lightly. Even treatment for leukemia may lead to the development of leukemia rash and leukemia infections. Thus, it is usually administered under a hospital setting, and patients are isolated with many precautions to prevent infections by opportunist agents. All of these measures are not excessive. They are fundamental for the recovery of the patient and his prognosis.
