What are the differences in the antimicrobial regimens?

AHA ESCEmpirical antibiotic

epidemiological factors

(“case by case basis”)

Defined for NVIE &

PVE, CA-IE & N/NN HCA

IE

VGS/S. gallolyticus IE No differences

ESC also recommends Amoxicillin

E. faecalis IE No differences

ESC also recommends Amoxicillin and Gentamicin is given QD

Staphylococcal NV IE No differences for MSSA and MRSA. Vancomycin first choice

for MRSA. ESC recommends as alternative trimethoprim–

sulfamethoxazole + clindamycin. Gentamicin QD/BID

Staphylococcal PVE No differences for MSSA and MRSA. Vancomycin first choice

for MRSA. ESC recommends Gentamicin QD/BID

Alternative as first line treatment for MSSA or

MRSA native valve endocarditis (ESC Guidelines)

• Rationale– High morbi-mortality for S. aureus endocarditis with current treatment guidelines

– Toxins ?

– One single center experience (‘letter’, n=31)

• Limitations– Two RCT found that TMP/SMZ is less effective than vancomycin for S. aureus BSI

– Clindamycin also inferior to vancomycin for BSI (RCT)

– Hematotoxicity associated with 6 weeks of high doses TMP/SMZ

– No evidence for any role of toxins in S. aureus endocarditis

PATHOGENESIS

Experimental Endocarditis Model

• Introduction






• No gentamicin for MSSA NA IE … but daptomycin?

• Role of rifampin – The ARREST Trial = No role !

• Better therapies for susceptible GP cocci

• Better therapies for MDR GP cocci

• New strategies: IV – Oral De-escalation (several RCT)

• Role of new antibiotics: Dalbavancin for OPAT,

Tedizolid for sequential oral therapy.

• Optimal treatment for HACEK, ABI/GRA, Fungal,

Whipple, Q fever and Bartonella IE

What are the problems when we are

treating MSSA/MRSA IE with Vancomycin?

- Poor bactericidal activity

- Poor diffusion within the vegetations

- Vancomycin MIC issues (AUC/MIC PD target)

- hVISA strains

- Tolerance

- … Renal toxicity

→ High rate of failures

• Introduction






• There are several differences between 2015 AHA and ESC Guidelines

regarding the recommend antibiotic regimens and their posology.

• In addition, the ID experts do not follow these recommendations,

especially with regard to staphylococcal endocarditis in NV and PVE

and NBC-IE.

• In the next few years, the role of daptomycin in combination and

dalbavancin (OPAT) should be defined, as well as the best

antimicrobial therapy for E. faecalis IE and whether the sequential IV -

oral de-escalation antimicrobial treatment is possible in IE.

• To change the guidelines, clinical trials and multicenter cohort studies

with a large number of patients will be necessary.
