ICAAC 2015 Facts and Figures
Q: What did* ICAAC stand for?
A: Interscience Conference on Antimicrobial Agents and Chemotherapy
*Last ICAAC, as we all know it
![Page 8: ICAAC 2015 Selection](https://reader036.vdocument.in/reader036/viewer/2022070515/58779bc41a28ab0f778b6fc9/html5/thumbnails/8.jpg)
ICAAC was the main ASM* conference:
• ASM + 40.000 members: one the largest (if not the largest) scientific
societies
• Multidisciplinary: Microbiologist, Infectious Diseases specialists,
PharmD and pharmacologists, biologists….
• Attendees:
ICAAC 2015 Facts and Figures
*ASM: American Society for Microbiology
ICAAC was losing appeal as compared w/ its previously back-to-back competitors:
ECCMID y IDSA
• 2015 ≈ 5,000 • 2014 ≈ 6,000
• 2013: 5400 (126 españoles)
• Traditionally: +10,000

ICAAC 2015 Facts and Figures • Medical Conference (especially ID) business model is
coming to an end- Regulatory limitations to the relationship healthcare industry and healthcare professionals…
- Antibiotics are not the most profitable drugs
- Information flows much much faster than some years ago
• but some are still trying to kill a goose that lays golden eggs
$250 early-bird ratePictures at conference forbidden (to enhance business)
- High registration price + Extras -6 hour-pre-ICAAC course: $375)
- Video scam: Slides/video library not included (as opposed to ECCMID)

Bloodstream infectionsErtapenem vs Other Carbapenems for the Treatment of Bloodstream Infections Due to Extended-spectrum β-lactamase-producing Enterobacteriaceae: A Multinational Pre-registered Cohort Study
• Multinational retrospective cohort (12 countries; 37 hospitals) • Patients with monomicrobial BSI due to ESBL-E (2004-2012)
Therapy Clinical cure/improvement
30-day mortality
Early empiric therapyErtapenem (32) vs other (163)
90.6% vs 75.4%1.87 (0.24-20.08)
3.1% vs 23.3%0.27 (0.02-4.03)
Targeted therapyErtapenem (205) vs other (504)
89.8% vs 82.6%1.04(0.44-2.50)
9.3% vs 17.1%0.93 (0.43-2.03)
“These results reinforce the idea that ertapenem should be considered an alternative to other carbapenems for treating such infections”
![Page 27: ICAAC 2015 Selection](https://reader036.vdocument.in/reader036/viewer/2022070515/58779bc41a28ab0f778b6fc9/html5/thumbnails/27.jpg)
Bloodstream infections(C-178) Is Ertapenem as Efficacious as Other Carbapenems for Infections Due to ESBL-producing Enterobacteriaceae in All Subgroups of Patients?
• Sensitivity analyses using multivariate logistic regression, propensity score and CART analyses were performed in different subpopulations (30-d mortality)
• Sensitivity analysis favors other carbapenems in patients with septic shock/severe sepsis (HR: 3.10; 95% CI: 0.86-11.20)
• In patients receiving ertapenem, renal failure was a protective factor for 30-day mortality (mortality, 0 vs 27.8%;p=0.08)
• Caution is needed when using ertapenem in cases of severe sepsis/septic shock in BSI due to ESBL-E
Conclusions
• The fact that renal failure have a protective effect for mortality in these patients might be due to increased ertapenem exposure in this population
