In a new preprint (NOT PEER REVIEWED) we continue to explore the challenge of overtreatment in community screening. It seems the benefits of TB treatment far outweigh the harms, especially once we accept that sputum culture is not perfect. Important food for thought. www.medrxiv.org/content/10.1...

For this reason the combination of Xpert CT and a detailed CXR examination seems to be best at identifying those who may relapse post treatment.

Daniel Grint @danieljgrint.bsky.social · 30/09/2025
They may all represent seperate pathways, except smear and CT which intuitively may be related based on sputum. The great benefit of Xpert CT is the automatic readout with no need for reader interpretation. I imagine much of the variability in culture/smear comes from the operator.

Daniel Grint @danieljgrint.bsky.social · 30/09/2025
Correlations between CT, culture and CXR were weak, it's only smear that was reasonably correlated with CT. Smear and culture were weakly correlated with each other (R^2 14%), but neither correlated with CXR (both R^2 <10%).

Hi Gabriele Ultra is worse than Xpert at differentiating between the higher levels of disease severity. The study population was skewed towards a higher degree of disease severity, which may explain the lack of correlation between Ultra and CXR.

I really dislike how science has started calling almost any fancy computational technique AI. 🧪 The framing of this entire article makes it sound like a benevolent AI independently made these drugs. That is *pure fantasy*. Instead: a team of scientists made a machine learning model for a study.

Delighted to see our long-acting injectible ART trial (IMPALA) presented at #IAS2025. 2-monthly injections are non-inferior to daily pill taking and overwhelmingly preferred. Next challenge is expanding access to LA ART; excellent news the WHO has recommended LA CAB+RPV in treatment guidelines.

Daniel Grint @danieljgrint.bsky.social · 17/07/2025
I think you'd probably be right to, assuming there are no potential ill effects. 'Statistical significant' i.e. <0.05 is less of a thing now, but you still have to respect the study design. In this case, they just missed the pre-defined superiority criteria and must report on those lines.
110
Daniel Grint @danieljgrint.bsky.social · 17/07/2025
You don't need a Bayesian analysis to be less rigid in interpreting p- values. You're right the result looks promising, but it requires further study.

Mandating culture/PCR for everyone in a vaccine trial makes sense to me, I didn't realise that wasn't the case. But it could (likely will) end up costing more even if the sample size is lower.

Daniel Grint @danieljgrint.bsky.social · 05/07/2025
Very interesting. In TB treatment trials, it's standard practice to test culture from everyone every few months regardless of symptoms. Consecutive positives define TB relapse without worrying about symptoms. However, this is a big cost driver!!!

Until there is a test for TB infection with higher specificity than IGRA, the use of the non-inferiority trial design for TB vaccine prevention of infection outcomes is not recommended. @richardwhite321.bsky.social @cfmcquaid.bsky.social @reinhouben.bsky.social

Daniel Grint @danieljgrint.bsky.social · 25/06/2025
TB vaccine trials testing a non-inferiority hypothesis with an infection primary outcome must account for the imprecision in the tools used to define infection, otherwise vaccines may be falsely declared non-inferior.
100
Daniel Grint @danieljgrint.bsky.social · 25/06/2025
With only modest departures from perfect specificity in tuberculosis infection markers (95% for both), the risk of falsely declaring a vaccine to be non-inferior to BCG (or any other active control) is substantial.

Optimising the use of currently available treatments through treatment stratification could reduce treatment duration by 2-months for the majority. TB treatment stratification strategies should be prospectively trialled in a phase III RCT. #TBSky

Among the majority who were classified as having limited TB disease at baseline, 4-months of treatment, including rifampicin at 1200mg but no quinolone, was non-inferior to the 6-month standard of care. This study adds to the body of evidence that the majority of people are over-treated for TB.

Daniel Grint @danieljgrint.bsky.social · 13/06/2025
We used baseline TB disease severity markers (Xpert cycle threshold and CXR grading) to define a TB disease phenotype (limited- and extensive-disease). Importantly for programmatic settings, we also show that Xpert CT alone was sufficient at identifying the limited-disease phenotype.
