WHO HIV Treatment Guidelines Updated
This just in:
WHO is now recommending that ART be initiated at a higher CD4 threshold of 350 cells/mm3 for all HIV-positive patients, including pregnant women, regardless of symptoms.
Which makes eminent sense, of course. Because if starting HIV therapy might prolong survival in developed countries, why shouldn’t it do the same in the developing world?
In fact, when you consider the higher incidence of TB and invasive bacterial infections in such settings, it could easily be argued — and has been argued — that starting early would net greater survival gains in resource-poor settings than it would here.
Plus, there’s the CIPRAHT001 Study, which proves it.
But there’s more — the new WHO guidelines also urge that countries “phase out” the use of stavudine in favor of less-toxic NRTIs, and that women continue breastfeeding so long as they are also on ART.
Good news all around.

FROM NEJM — Recent Infectious Disease Articles- Scrofuloderma August 29, 2026A 72-year-old man presented with a 2-month history of a painful lump on his neck. Cytologic analysis of fine-needle aspirate was consistent with suppurative lymphadenopathy. The lesion subsequently ulcerated and released purulent discharge.
- Response-Tailored or Standard-Duration Antibiotic Treatment for Infective Endocarditis August 28, 2026Among adults with endocarditis caused by S. aureus, E. faecalis, or streptococcus species, tailored-duration antibiotic therapy led to 13 more days alive without antibiotics than standard therapy, but with a higher incidence of relapse.
- Severe Plasmodium falciparum Malaria August 20, 2026An 82-year-old man was brought to the ED after being “found down.” One week earlier, he had returned from a 1-month visit to Chad. A peripheral-blood smear showed ring-form trophozoites within erythrocytes.
- Case 24-2026: A 74-Year-Old Man with Dyspnea, Proximal Muscle Weakness, and Hypoxemia August 20, 2026A 74-year-old man with myasthenia gravis was evaluated for dyspnea, proximal muscle weakness, hypoxemia, and a painful tongue lesion. Medications included prednisone and mycophenolate mofetil. A diagnosis was made.
- A Regional Measles Outbreak — South Carolina, 2025–2026 August 13, 2026In South Carolina, 997 measles cases occurred in the reported outbreak. In one health care system, 81 cases were identified. Most were in unvaccinated persons; 13 persons were hospitalized, and 2 had measles encephalitis.

Should the guidelines have suggested initiation at < 500 as is expected in the next iteration of US centered guidelines? Although ARVs are limited in many parts of the world should an individual patient be witheld therapy when there is an accumulation of data suggesting 500 (or higher) may be the tipping point? A conundrum in areas where supplies of ARVs are limited perhaps.
CM,
I guess one way of looking at “start at CD4 350” is “start at CD4 > 350.” I realize it’s not exactly the same thing, but since you can’t predict when or if the CD4 will drop, as a pt approaches this threshold (i.e., between 350 and 500), it’s time to get ready to start.
As you know, DHHS guidelines just out as well.
