الإجابة: D. CD4 <200 cells/mm3
PJP occurs when the CD4 count falls below 200 cells/µL, which is also the AIDS-defining threshold. That CD4 level is the indication for TMP-SMX prophylaxis.
- Viral load, oral hairy leukoplakia and nonspecific cough/fever are not the indication for PJP prophylaxis.

ليش غلط
Prophylaxis is meant to prevent PJP and is tied to the CD4 count below 200. Dry cough, fever and shortness of breath are what PJP itself looks like once it has started, so they are not the trigger for prophylaxis.

ليش غلط
In the lecture, PJP prophylaxis is tied to the CD4 count (below 200), not to the viral load. A high viral load is not the trigger for TMP-SMX prophylaxis.

PJP occurs when the CD4 count falls below 200, and prophylaxis with trimethoprim/sulfamethoxazole (TMP-SMX) is started at that threshold.
