HIV

17 cases on ART timing and regimen selection, PrEP and PEP, drug interactions, resistance-guided salvage therapy, and opportunistic-infection prophylaxis and IRIS management — choose a case below to open its full multi-voice debate.

Infectious DiseaseHIV
ART Timing in TB/HIV Coinfection: Racing the CD4 Count

A CD4 count of 38 and a five-day-old TB diagnosis put the team on a clock most trial evidence has already read for this exact number -- the disagreement is about how much lead time his lungs deserve first.

Case 0001
Infectious DiseaseHIV
Cryptococcal Meningitis: The Trial That Says Wait

For most opportunistic infections, earlier antiretroviral therapy saves lives. Cryptococcal meningitis is the one place a randomized trial found the opposite, and the team has to decide how literally to read it.

Case 0002
Infectious DiseaseHIV
Acute PCP: The Same Question, the Opposite Answer

The same ART-timing question that argues for waiting in cryptococcal meningitis argues for moving quickly here — a direct, deliberate contrast built on the same underlying trial logic landing in opposite places.

Case 0003
Infectious DiseaseHIV
A Two-Drug Regimen, Right at the Edge of the Trial That Approved It

A viral load of 720,000 sits well past the exact number that kept patients like him out of the trial establishing two-drug ART as a first-line option — the question is how much that exclusion should actually govern his regimen.

Case 0004
Infectious DiseaseHIV
Long-Acting Injectable Therapy, Stacked Against Her Own History

A decade of perfect suppression argues for trusting her with a simpler regimen. A resistance test from the very beginning of that decade argues the opposite, and neither fact cancels the other out.

Case 0005
Infectious DiseaseHIV
PrEP That Doesn't Depend on Remembering

His oral PrEP keeps lapsing for the same reason most people's does — daily life gets in the way — and an injection every two months promises to remove that problem. It also introduces a different one, further out, that daily pills never carried.

Case 0006
Infectious DiseaseHIV
Post-Exposure Prophylaxis, Sixty Hours Late

A needlestick with visible blood and an unknown source isn't the borderline case the old two-drug-versus-three-drug debate was built for — the real question tonight is whether sixty hours is still soon enough to matter.

Case 0007
Infectious DiseaseHIV
Twenty Years of Vivid Dreams

Twenty years of tolerated side effects is its own kind of evidence that something should change — the complication is that the one record that would make the switch straightforward predates his clinic's electronic chart by a decade.

Case 0008
Infectious DiseaseHIV
Three New Drugs, Thirty Years of Resistance to Work Around

Three genuinely novel agents, each active by a different mechanism than the resistance sitting in his chart, and no head-to-head trial to settle which combination actually fits a patient whose treatment history predates all three of them.

Case 0009
Infectious DiseaseHIV
Five Weeks Pregnant, and the Data That Finally Caught Up

The dolutegravir-pregnancy controversy that once made headlines has moved substantially since 2018 — the harder question now is how much residual caution five weeks of gestation still deserves, not whether the original alarm was fully justified.

Case 0010
Infectious DiseaseHIV
Choosing a Statin Around a Drug That Blocks Most of Them

Every statin option interacts with ritonavir to some degree — the real decision is which interaction is most predictable and most manageable, not which one to pretend doesn't exist.

Case 0011
Infectious DiseaseHIV
Stopping a Pill That's Been Working Fine

His CD4 count clears the discontinuation threshold today, comfortably. Whether it has done so for the length of time the guideline actually asks for depends on how one dip four months ago gets read.

Case 0012
Infectious DiseaseHIV
Undetectable Without Ever Taking a Pill

Seventeen years without a single antiretroviral dose and an undetectable viral load the whole time is either a reason to leave well enough alone, or exactly the kind of unusual biology the team can't yet fully explain — and that uncertainty cuts both ways.

Case 0013
Infectious DiseaseHIV
The Swelling Is Real, and So Is What Happens If ART Stops

Everyone in the room agrees the inflammation is real and worsening. What's contested is whether treating it around a continued, working antiretroviral regimen is still the safer path, or whether his imaging has already crossed into territory that argues for pulling ART back.

Case 0014
Infectious DiseaseHIV
A Kidney Number That Rules Out the Easy Answer

His declining kidney function makes his current regimen a poor long-term fit — but each realistic alternative carries a different organ-specific risk of its own, and neither is clearly the safer trade.

Case 0015
Infectious DiseaseHIV
Acute HIV, and the Case for Starting Before the Ink Is Dry

Every day of delay plausibly lets the viral reservoir seed further and gives him more time to disengage from care before treatment starts — the counterargument is that treating blind, before knowing his resistance profile, carries its own real cost.

Case 0016
Infectious DiseaseHIV
Twice a Year, Against Once Every Two Months

Both options in front of her are genuinely excellent by historical PrEP standards — the real disagreement is whether the newer drug's larger efficacy number should outweigh the older one's much longer track record, and whether either question matters as much as what her insurance will actually cover.
