Minimum inhibitory concentration ≤ 0.12 μg/mL.
:† Preferred in most patients >65 y or patients with impairment of 8th cranial nerve function or renal function.
:₳ Pediatric dose should not exceed that of a normal adult.
:‡ 2-wk regimen not intended for patients with known cardiac or extracardiac abscess or for those with creatinine clearance of <20 mL/min, impaired 8th cranial nerve function, or Abiotrophia, Granulicatella, or Gemella spp infection; gentamicin dosage should be adjusted to achieve peak serum concentration of 3-4 μg/mL and trough serum concentration of >1 μg/mL when 3 divided doses are used; nomogram used for single daily dosing.
:¶ Vancomycin therapy recommended only for patients unable to tolerate penicillin or ceftriaxone; vancomycin dosage should be adjusted to obtain peak (1 h after infusion completed) serum concentration of 30–45 μg/mL and a trough concentration range of 10–15 μg/mL
:฿ Other potentially nephrotoxic drugs (eg, nonsteroidal antiinflammatory drugs) should be used with caution in patients receiving gentamicin therapy. Although it is preferred that gentamicin (3 mg/kg) be given as a single daily dose to adult patients with endocarditis due to viridans group streptococci, as a second option, gentamicin can be administered daily in 3 equally divided doses.

*Dosages recommended are for patients with normal renal function.
:† Penicillin or ceftriaxone together with gentamicin has not demonstrated superior cure rates compared with monotherapy with penicillin or ceftriaxone for patients with highly susceptible strain; gentamicin therapy should not be administered to patients with creatinine clearance of <30 mL/min.
:‡ Although it is preferred that gentamicin (3 mg/kg) be given as a single daily dose to adult patients with endocarditis due to viridans group streptococci, as a second option, gentamicin can be administered daily in 3 equally divided doses.

*Patients with endocarditis caused by these strains should be treated in consultation with an infectious diseases specialist.
*Cardiac valve replacement may be necessary for bacteriologic cure.
*Cure with antimicrobial therapy alone may be < 50%
*Severe, usually reversible thrombocytopenia may occur with use of linezolid, especially after 2 wk of therapy.
*Quinupristin-dalfopristin only effective against E faecium and can cause severe myalgias, which may require discontinuation of therapy
*Only small no. of patients have reportedly been treated with imipenem/cilastatin-ampicillin or ceftriaxone + ampicillin.

==Culture Negative Endocarditis==
*Clinical course of infection beside the epidemiological features should be considered upon selecting treatment regimen.

====Patients Who Received Antibiotic Therapy Before the Blood Culture====
*Patients with acute clinical presentations with native valve infection: coverage of S. aureus should be followed as detailed in proven staphylococcal disease.
*Patients with subacute presentation: antibiotic coverage for S. aureus, viridians group streptococci, and enterococci should be considered.
*Antibiotics for HACEK group of organism also should be considered.
*Symptomatic patients with prosthetic valve and culture negative infection within 1 year of valve replacement should receive vancomycin to cover the oxacillin-resistant staphylococci.
*Symptomatic patients with prosthetic valve and culture negative infection within 2 months of valve replacement should also receive cefepime for gram negative bacilli coverage.
*Symptomatic patients with prosthetic valve more than 1 year, the most likely causing organisms are oxacillin-susceptible staphylococci, viridians group streptococci, and enterococci.  Antibiotic coverage for those organisms should be continued for at least 6 weeks.
====Patients with Culture-Negative Endocarditis and Suspected Infection with Uncommon Endocarditis Pathogens====
*Examples of these pathogens include Bartonella species, Chlamydia species, Coxiella burnetii, Brucella species, Legionella species, Tropheryma whippleii, and non-Candida fungi.
*The most common pathogens that have been reported with culture-negative endocarditis are [[Bartonella|Bartonella species]], [[Coxiella burnetii]], and [[Brucella|Brucella species]].
*Antibiotic therapy for these pathogens should include aminoglycosides for at least 2 weeks.
*Therapeutic regimens for Bartonella endocarditis based on the [[Endocarditis causes|epidemiological risk]] and high index of suspicion.

Overview

Blood cultures should be drawn prior to instituting antibiotics to identify the etiologic agent and to determine its antimicrobial susceptibility. Older antibiotics such as penicillin G, ampicillin, nafcillin, cefazolin, gentamycin, ceftriaxone, rifampin and vancomycin are the mainstays of therapy.

Timing of Initiation of Antibiotics

Antibiotic therapy for subacute or indolent disease can be delayed until results of blood cultures are known; in fulminant infection or valvular dysfunction requiring urgent surgical intervention, begin empirical antibiotic therapy promptly after blood cultures have been obtained.

Duration of Antibiotic Therapy

The duration for native valve endocarditis is often 4 weeks. For prosthetic valve endocarditis (including the presence of a valve ring), treatment should be continued for 6 to 8 weeks. For each infective agent, the preferred antimicrobial agent, dose, and duration is listed below.

Empirical Antibiotic Therapy

  • Antibiotic therapy for subacute hemodynamically stable disease, and in those who have received antibiotics recently can be delayed waiting for the results of blood cultures, as this delay allows an additional blood cultures without the confounding effect of empiric treatment, which is very important in determining the causing pathogens.[1]
  • On the other hand, the rapid progression of acute cases necessitates the start of empirical treatment antibiotic therapy once the blood cultures have been collected.
  • Empirical therapy is needed for all likely pathogens, certain antibiotic agents, including aminoglycosides, is preferably avoided for its toxic effects.
  • Clinical course of infection beside the epidemiological features should be considered upon selecting empirical treatment regimen.
  • Consultation with an infectious disease specialist for the selection of one of the antibiotic regimens is recommended (see therapy for culture-negative endocarditis). [2]
