Pseudomonas sparing’ antibiotics, is it time to rethink this notion?

Super interesting: Ceftriaxone-R E.coli / K.pneumoniae BSI(n=163) 2022-24
🧬blaCTX-M+:85.3%
🧬 No-blaCTX-M:14.7%
⚠️🔼 No-blaCTX-M ceftriaxone R
⏱ CTX-M+:faster optimal therapy
💡 Molecular testing still useful for ESBL detection→always confirm with AST

Super interesting cUTI case with Klebsiella pneumoniae treated with pip tazo.
Day 1:S to pip tazo
Day 7:R to pip tazo
👉 Classic reminder: heteroresistance can hide in plain sight
Even BMD may fail to detect it reliably
👉 Clinically linked to treatment failure in reported cases

Researchers paid $1.06 billion to five academic publishers from 2015-2018 to publish their papers.

Academic publishers sold the same papers back to researchers for $2 billion.

[Patrick Harris @padstamundo]

@BradSpellberg @ABsteward Couldn’t agree more - we should all be more accepting of how much we don’t know for sure and encourage enrolment into clinical trials where evidence is lacking

[Patrick Harris @padstamundo]

@ABsteward @DrToddLee @ESCMID Steve summed up the current state of things well; MERINO was underpowered but the alarming mortality signal at interim analysis was a whisker off our stopping boundary - so we couldn’t in conscience continue to enrol with equipoise; AST errors with PTZ compounded our concerns

[Patrick Harris @padstamundo]

@JohnGolf_CA @ABsteward @jesusrbano 💯 agree

[John Silver @JohnGolf_CA]

@padstamundo @ABsteward @jesusrbano CEFMEC deserved better than poster hall. 2% vs 5.2% mortality is massive - finally have real carbapenem-sparing options alongside ASTARTÉ.

[Patrick Harris @padstamundo]

@davidantibiotic Other important differences - MERINO included patients with septic shock, PETERPEN used 3h infusions - may have made a difference? PETERPEN also had an overall much higher mortality (14%) ...

[Patrick Harris @padstamundo]

Looking forward to the ESBL RCT session #ESCMIDGlobal2026 - PETERPEN, @MerinoTrial and ASTARTE in a tussle to determine how we should treat ESBL bloodstream infections... great to see more trials tackling this important question and seeking alternatives to carbapenems

[Patrick Harris @padstamundo]

@davidantibiotic discusses the implications from PETERPEN and MERINO.. how do we make sense of the differences? outlines the important of OXA-1 on PTZ MICs... were there differences in the organisms in each trial? https://t.co/ZvzuQ2am3r

[Patrick Harris @padstamundo]

@davidantibiotic We have also analysed MERINO with a win-ratio to explore outcomes beyond mortality alone - still seemed to suggest improved outcomes with meropenem https://t.co/8zN3luwaA4

[Patrick Harris @padstamundo]

#ESCMIDGlobal2026 ASTARTE RCT, temocillin vs carbapenem - was presented last year, now post hoc analysis comparing ertapenem vs meropenem-> prim. endpoint of clinical success; NI shown in overall study; no obvious differences if erta vs mero used, some imbalances however..
