One immune count and several prevention questions
A fictional person beginning HIV care has an immune count that raises concern for opportunistic disease. The trainee copies a single prophylaxis threshold onto PJP, toxoplasmosis and disseminated MAC, then assumes that every positive antigen test can be managed without further investigation. The actual record has not yet supplied organism-specific serology, effective-ART timing, symptoms or the relevant CNS assessment. The supervising clinician asks the trainee to separate primary prophylaxis, treatment of established disease and the consequences of immune recovery. The case intentionally does not give a complete diagnosis or ask for a drug dose. It tests the need for disease-specific reasoning rather than a universal low-count prescription.
1. Why is the copied threshold approach unsafe?
Read the worked answer
Different infections use different risk and treatment conditions, and effective ART or a suspected established infection can change the question.
2. Which distinctions should be made first?
Read the worked answer
Identify the organism, whether the aim is prevention or treatment, the relevant clinical and test findings, and whether CNS disease or another condition changes timing and management.
