ART initiation timing — DTM&H MCQ

Correct answer: E — Initiate immediately (same day if possible)

The correct answer is E, initiate immediately (same day if possible). Since the WHO treat-all policy, all people living with HIV are eligible to start antiretroviral therapy regardless of CD4 count, clinical stage, or age, and this asymptomatic man with no TB symptoms and a CD4 of 320 has no clinical contraindication to rapid start. WHO guidance, which underpins Malawian and DTMH-relevant practice, defines rapid initiation as within seven days of diagnosis, with same-day initiation offered once active TB and cryptococcal meningitis have been clinically excluded. Same-day start improves linkage and retention in care without compromising safety when the patient is clinically well and motivated. There is no CD4 threshold or viral load gate, and TB preventive therapy (IPT) is given alongside, not before, ART. Why the other options are wrong: C. Defer until CD4 below 200: This reflects outdated CD4-staged eligibility criteria abandoned once treat-all was adopted; waiting risks disease progression and loss to follow-up. D. Start only if viral load exceeds 100,000: Viral load is used for monitoring response and adherence, not as an eligibility gate for starting ART under current policy. B. Defer until CD4 below 350: This was the pre-2015 threshold-based approach; current guidance removed all CD4 thresholds for treatment eligibility. A. Start after 6 months of IPT first: Isoniazid preventive therapy is given concurrently with ART, not as a prerequisite delaying initiation; sequencing it first would unnecessarily postpone treatment and increase attrition risk. Key point: Under WHO treat-all policy, ART eligibility is universal regardless of CD4 count or viral load, and same-day initiation should be offered once TB and cryptococcal meningitis have been excluded clinically.
