Which preventive measures should be taught to reduce opportunistic infections other than Pneumocystis jirovecii pneumonia (PJP) in people living with HIV?

• A. Vaccinations as appropriate, prophylaxis for toxoplasma if CD4 < 100, MAC prophylaxis if CD4 < 50, avoid raw or undercooked foods and unpasteurized products
• B. Vaccinations only
• C. Prophylaxis for toxoplasma only
• D. Avoid all vaccines and dietary restrictions

Answer: (A)

The main idea is that preventing opportunistic infections in people living with HIV relies on three integrated strategies: up-to-date, appropriate vaccinations; targeted prophylaxis based on how suppressed the immune system is (CD4 count); and safe-food practices to limit exposure to common pathogens. Vaccinations help prevent infections that vaccines can stop, such as influenza and pneumococcus, as well as other vaccines like hepatitis B or HPV as indicated. When the CD4 count drops to certain thresholds, specific prophylaxis is recommended to guard against particular opportunistic organisms; for example, toxoplasma prophylaxis is advised when CD4 is under 100, typically using TMP-SMX, and MAC prophylaxis is advised when CD4 is under 50, often with azithromycin or clarithromycin. Dietary precautions, such as avoiding raw or undercooked meats and unpasteurized dairy products, reduce the risk of ingesting pathogens like toxoplasma and Listeria. Put together, these measures address opportunistic infections beyond Pneumocystis jirovecii pneumonia by strengthening defenses through vaccination, preventing exposure with prophylaxis when needed, and minimizing ingestion of high-risk foods.
