Colistin is nephrotoxic / Antibiotic stewardship knowledge gaps / Fire extinguisher video

Dear All, To start your week, we have three tidbits for consideration.

First, results from a trial entitled “Colistin versus meropenem in the empirical treatment of ventilator-associated pneumonia (Magic Bullet study): an investigator-driven, open-label, randomized, noninferiority controlled trial” have been published (Critical Care 23:383, 2019, link). Cisneros et al. sought to enroll 496 subjects into this trial but terminated the study due to excessive nephrotoxicity in the colistin arm after enrolling only 232 subjects. Mortality in the two arms was similar at 23-25% but rates of renal failure (40/120, 33.3% for colistin versus 21/112, 18.8% for meropenem; p = 0.012) and renal replacement therapy (11/120, 9.1%, versus 2/112, 1.8%; p = 0.015) were such that that the trial’s Data Safety Monitoring Board recommended early study termination. These data reinforce the need for guidelines (link) to move the community away from colistin and into use of the newer generation agents.

Second, we have a very thoughtful paper entitled “Research Needs in Antibiotic Stewardship” by Morris et al. in Infection Control and Hospital Epidemiology 2019;40(12):1334-43 (link, but article is behind a paywall; a related press release gives a good summary, link). Many of the themes in this paper are similar to those discussed at the 18-19 Nov 2019 FDA-IDSA-NIH-Pew workshop (same link as cited just above regarding guidelines): we lack data to define optimal antibiotic prescribing practices and we don’t know how to best implement good stewardship in diverse settings. Good research on optimal use would encourage use of the best antibiotics (e.g., NOT colistin!) and hence be a win-win for the entire community.

 

Finally, the DRIVE-AB/IMI team have turned one of my favorite metaphors into a 60-second video. Antibiotics are indeed the #FireExtinguishersOfMedicine!

Cheers!  –jr

In Praise of Non-Inferiority

Dear All (wonkish but intended for everybody to read and absorb): There’s been a lot of recent discussion about “lessons learned from COVID-19.” Indeed, there are many valuable points: global cooperation, preparedness, supply chains, and so forth. As an example, I note the 17 Sep 2020 communique from the G20 Health Ministers (link): it was heavily

FDA and EMA regulatory updates / Fireside chat during the 4th AMR Conference

Dear All (lots and lots of wonkish detail here, be sure your blood caffeine level is adequate!), During the 24-28 Aug 2020 BEAM Alliance-sponsored AMR Conference (go here or see below my signature for more), I had the opportunity on 27 August to chat with Sumati Nambiar (FDA) and Marco Cavaleri (EMA) about ongoing regulatory activities. The

Treating resistant Gram-negatives: IDSA provides pragmatic expert advice

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). 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

New antibiotics are not being registered or sold in Europe in a timely manner

Dear All (and with thanks to Kevin for leading the charge on this newsletter), While listening to last week’s BEAM-sponsored AMR Conference (really a wonderful conference, thank you Team BEAM, go here to listen to the sessions), we tumbled onto a really, really disturbing trend: New antibiotics are not being registered or sold in Europe in
