Wooo last OTILT, congrats!

Jeff Pearson @jeffpears0n.bsky.social · Jun 11

Correct! Since AUCs >~650 have been associated with toxicity

Jeff Pearson @jeffpears0n.bsky.social · Jun 10

We did include all MIC comers, but did not collect that data! We today still have no problem targeting an AUC of 400-600 for CoNS even with an MIC of 2, although not based on any great published data

Three new UTI antibiotics active vs. ESBL organisms have been approved by the FDA in the past year alone! Which will make it to market first: pivmecillinam, sulopenem-probenecid, or gepotidacin? #IDsky

The aztreonam-avibactam (Emblaveo) FDA approval Friday flew wayyyy under the radar without the normal FDA alerts or AMDAC review. But AbbVie has the press release (news.abbvie.com/2025-02-07-U...) and the FDA package insert is now available! www.accessdata.fda.gov/drugsatfda_d...

Yes, that’s exactly what we did! Should’ve put that in the methods

Great to see the CACTUS study in print! authors.elsevier.com/c/1kHGc5E-Uo... Ceftaz-avi vs. Ceftol-tazo for MDR Pseudomonas. Tremendous effort by all involved, and thanks to a great leadership team. The PRECEDENT network is cooking up much more, check it out at www.precedentnetwork.com! #IDsky

I'm excited to join the #IDSky 🦋 community! What better way to start than with our study that flew under the radar last month integrating vancomycin AUC monitoring in OPAT, which saw HUGE drops in AKI rates (23% to 6% overall). Safe to say AUC is here to stay! academic.oup.com/ofid/article...

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

Thank you @IDSAInfo for this honor! I'm humbled to become a fellow of IDSA, especially being just 1 of 8 PharmDs recognized with #FIDSA this year. I can't wait to see everyone in LA in October at @IDWeekmtg! #WeAreID

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

Concomitant carbapenem & valproate use is THE most relevant drug interaction I teach residents & students about. In our review, seizures occured in 46% of encounters😱. Avoid this combination at all costs in patients using valproate for seizure control!

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

Alright #IDTwitter, what would you recommend in the situation below? Source control unattainable, infected graft so hoping for short-term acute treatment and long-term suppression. NDM positive Providencia rettgeri

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

Our new study evaluating gentamicin dosing strategies for endocarditis was published in @jac_amr! We saw HUGE rates of nephrotoxicity (~50%) in the divided dosing group. Next research question from our MGB group - time to ditch gent altogether?

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

Catching up on podcasts today, I had the best random back-to-back listening experience! Looking at the pip-tazo breakpoints from two different angles, great discussion in both from @SIDPharm and @ASMicrobiology & #IDTwitter

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

The tixagevimab-cilgavimab (Evusheld) EUA was revoked today by the FDA, marking the end of these #COVID Mab posts from me for the foreseeable future. #IDtwitter

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

ASPE/HHS published a breakdown of oral #COVID19 treatment utilization by state last week - Paxlovid vs. molnupiravir. As I expected, Massachusetts is on the far end of the spectrum favoring Paxlovid... #IDTwitter 1/2

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

The @US_FDA officially withdrew bebtelovimab's EUA this week as variant resistance has surpassed 65%, following in the steps of many #COVID Mabs before it. The only Mab left standing (barely) is Evusheld (79% resistant, but no alternatives) #IDTwitter

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

I also have joined med Mastodon and will likely be moving over to that platform gradually in the coming weeks, come along for the ride! #medmastodon #IDmastodon #IDTwitter

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

I missed last Friday's Tweet, so I added some extra insight in this post. Updated Mab variant table, with expected susceptibility against circulating variants in the second image (per ). We shut down bebtelovimab last week at BWH #IDTwitter #COVID19

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

While not much has changed on my Mab table since the last post, a whole lot has changed with the current #COVID variants. We're now looking at ~27% resistance to bebtelovimab and ~50% resistance to Evusheld. Stay tuned for updates from @NIHCOVIDTxGuide

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

This may need to be a weekly Tweet based on how quickly the #COVID19 Omicron variants are changing. Below is the updated COVID Mabs table, and just as importantly the variant situation right now in the US. Note the variants quickly rising to the top of the list... #IDTwitter

Jeff Pearson @jeffpears0n.bsky.social · Nov 21

Omicron continues its never-ending variant kick! BA.4.6 & BA.2.75 are added below. This will be my last variant table that is all-inconclusive. In order to make more readable going forward it will just be with active(ish) variants and #COVID Mabs #IDTwitter
