What CD4 count is indicative of a well-managed HIV patient, in addition to having low viral copies?

1. CD4 count of 100

2. CD4 count undetectable

3. CD4 count of 500

4. CD4 count of 50

The correct answer is: CD4 count of 500

A CD4 count of 500 is indicative of a well-managed HIV patient, reflecting a strong immune system and effective treatment. This level suggests that the antiretroviral therapy (ART) is working well, allowing the body's immune system to recover and maintain its function. Patients with a CD4 count at this level typically have a reduced risk of opportunistic infections, which is a critical aspect of managing HIV effectively. A higher CD4 count indicates that the immune system is relatively healthy, assuming that the patient also has low viral load, which is crucial for preventing disease progression and maintaining overall health. In contrast, a CD4 count of 100 or 50 would indicate significant immune compromise and a higher risk for opportunistic infections, which is not characteristic of a well-managed patient. An undetectable CD4 count is not a viable measure, as CD4 cells are a type of T-cell and their counts can be measured numerically; they cannot be 'undetectable' in the same way as viral load. Therefore, a CD4 count of 500 alongside low viral copies presents the best picture of effective HIV management.
