Leukemia patients may require which type of prophylaxis due to immunosuppression?

• A. Prophylactic antibiotics
• B. Exclusive prophylactic antifungals
• C. No prophylaxis is needed
• D. Prophylactic antivirals only

Answer: (A)

When chemotherapy causes neutropenia, the body's defenses against bacteria drop sharply and mucosal barriers can be damaged, allowing bacteria to invade more easily. Because bacterial infections are the most immediate and common danger in this setting, giving prophylactic antibiotics helps prevent fever and serious infections during the high-risk neutropenic period. Fluoroquinolone-type antibiotics are commonly used for this purpose in many guidelines, reducing infection-related complications.

Antifungal prophylaxis is important when the risk of fungal infection is high or when neutropenia is prolonged, but it does not address the broad bacterial threats seen early in immunosuppressed patients. antiviral prophylaxis is useful for specific viral risks in certain patients, but by itself it doesn’t cover the prevalent bacterial infections. No prophylaxis would leave patients vulnerably exposed to infections during neutropenia.
