Dear All,
IDSA (Infectious Diseases Society of America) have today released an eagerly awaited new guidance document on treating infections due to resistant Gram-negative bacteria (link).
8 Apr 2021 update: IDSA have published an updated version of this document. It excellent to see IDSA working steadily to provide up-to-the-minute advice!
24 Nov 2021 update: IDSA have maintained their concept of incremental edits to this guidance by releasing the next version of their guidance!
The thing that makes this document unusual is that it is an expert guidance rather than a formal guideline. Although there is value in formal guidelines that carefully review all data using a GRADE (Grading of Recommendations Assessment, Development, and Evaluation) framework, such guidelines take a long time to create and are only updated infrequently.
Based on a recognition that lack of timely guideline updates meant that inferior colistin-based regimens were being used reasonably commonly, a discussion of guidelines ensued during the 18-19 Nov 2019 FDA-IDSA-NIH-Pew Workshop on “Enhancing Antibacterial Trials In The US” (link to a newsletter on a report from Alan Carr showing continued use of colistin, link to a newsletter with yet more data on the toxicity of colistin, link to a newsletter about the 18-19 Nov meeting).
At that meeting, we concluded there was a need for a living guidance document that included the sort of thing that one peer would tell another about approaches to difficult situations. The idea was that the treating physician must respond to the situation at hand based on available knowledge and that having insights from such a document would be infinitely better than the haphazard data you might find if you went to the library and searched to find the available tidbits.
So, we now have this first-ever guidance document from IDSA on treatment of resistant Gram-negatives. Authored by a well-respected group of authors (Tamma, Aitken, Bonomo, Mathers, van Duin, and Clancy) that includes both adult and pediatric specialists, the introduction makes clear the special character of this document:
- “IDSA acknowledged that the ability to address rapidly evolving topics such as AMR was limited by prolonged timelines needed to generate new or updated clinical practice guidelines.
- “As an alternative and complement to comprehensive clinical practice guidelines, IDSA endorsed developing more narrowly focused guidance documents for the treatment of specific infectious processes.
- “Guidance documents will address specific clinical questions for difficult-to-manage infections that are not covered by present guidelines.
- “The documents will be prepared by a small team of experts based on a comprehensive (but not necessarily systematic) review of the literature. Additionally, such guidance documents will not include a formal grading of the evidence, unlike IDSA guidelines, which utilize the GRADE framework.
- “Over time, guidance documents may be transitioned to a GRADE format. Content will be disseminated on multiple platforms and updated as new data emerge.“
So, this is exactly what we wanted … up-to-date advice from experts who have reviewed the known and then tackled the hard questions that arise about the unknown. The document takes a Q&A format and works serially through topics around ESBL-producing Enterobacterales, CRE, and DTR Pseudomonas aeruginosa (link to a newsletter about these acronyms; be sure to take time to refresh your understanding of the important new idea of DTR, Difficult-to-Treat Resistance). In the Q&A, I would draw your attention to Question 6 in the section on CRE:
- Q: “What is the role of polymyxins for the treatment of infections caused by CRE?”
- A: “Polymyxin B and colistin should be avoided for the treatment of infections caused by CRE. Colistin can be considered as a last resort for uncomplicated CRE cystitis.”
With thanks to IDSA and the expert authors: Here’s to seeing this guidance improve outcomes for our patients by moving the community away from colistin in favor of better products!
All best wishes, –jr

Upcoming meetings of interest to the AMR community:
- (it’s over now, but you can still watch it!) 24-28 Aug 2020 BEAM Alliance-sponsored AMR Conference. Go here to access the recorded sessions. This was a very, very good meeting! In particular, please note these two sessions from the final day … both are free on YouTube:
- “Spotlight on UK | The Investor Action on AMR” (link). Chaired by Louise Norton-Smith (Head of Global AMR Strategy & Delivery, UK Dept of Health) with a key note by Dame Sally Davies (UK Special Envoy on AMR) in which we learn why we should #SaveTheLobster (see notes in this newsletter).
