==Overview==
==Overview==
[[Antimicrobial]] therapy is the mainstay of therapy for [[endocarditis]]. [[Empiric therapy|Empiric]] antimicrobial therapy depends on the nature of the [[valve]] (native vs. [[Prosthesis|prosthetic]]) and the onset of [[endocarditis]] following [[valve]] implantation (less than 1 year vs. more than 1 year). In patients with [[endocarditis]], [[Antithrombotic therapy|antithrombotic]] therapy may be administered when needed. The [[prothrombin time]] must be carefully monitored as [[anticoagulant]]s may cause or worsen [[hemorrhage]] in patients with endocarditis. [[Heparin]] administration should be avoided if possible.


[[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.  Empiric antiomicrobial therapy is started once the blood cultures have been collected.

===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 culture]]s, as this delay allows an additional blood cultures without the confounding effect of [[Empirical|empiric]] treatment, which is very important in determining the causing [[pathogens]].<ref>{{Cite book  | last1 = Braunwald | first1 = Eugene | last2 = Bonow | first2 = Robert O. | title = Braunwald's heart disease : a textbook of cardiovascular medicin | date = 2012 | publisher = Saunders | location = Philadelphia | isbn = 978-1-4377-2708-1 | pages =  }}</ref>
* 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.
* 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]]). <ref name="Baddour-2005">{{Cite journal | last1 = Baddour | first1 = LM. | last2 = Wilson | first2 = WR. | last3 = Bayer | first3 = AS. | last4 = Fowler | first4 = VG. | last5 = Bolger | first5 = AF. | last6 = Levison | first6 = ME. | last7 = Ferrieri | first7 = P. | last8 = Gerber | first8 = MA. | last9 = Tani | first9 = LY. | title = Infective endocarditis: diagnosis, antimicrobial therapy, and management of complications: a statement for healthcare professionals from the Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease, Council on Cardiovascular Disease in the Young, and the Councils on Clinical Cardiology, Stroke, and Cardiovascular Surgery and Anesthesia, American Heart Association: endorsed by the Infectious Diseases Society of America. | journal = Circulation | volume = 111 | issue = 23 | pages = e394-434 | month = Jun | year = 2005 | doi = 10.1161/CIRCULATIONAHA.105.165564 | PMID = 15956145 }}</ref>


==Timing of Initiation of Antibiotics==
===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.
* [[Antibiotic]] therapy for the [[subacute]] or indolent disease can be delayed until results of blood cultures are known.

==Duration of Antibiotic Therapy==
===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.

Overview

Antimicrobial therapy is the mainstay of therapy for endocarditis. Empiric antimicrobial therapy depends on the nature of the valve (native vs. prosthetic) and the onset of endocarditis following valve implantation (less than 1 year vs. more than 1 year). In patients with endocarditis, antithrombotic therapy may be administered when needed. The prothrombin time must be carefully monitored as anticoagulants may cause or worsen hemorrhage in patients with endocarditis. Heparin administration should be avoided if possible.

Medical Therapy

Empirical Antibiotic Therapy

Timing of Initiation of Antibiotics

  • Antibiotic therapy for the 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 of 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 are listed below.

Antimicrobial Regimens

  • 1. Culture-negative endocarditis
  • 1.1. Culture-negative, native valve endocarditis
  • 1.2. Culture-negative, prosthetic valve endocarditis (early, ≤ 1 year)
  • 1.3. Culture-negative, prosthetic valve endocarditis (late, > 1 year)
  • 1.4. Culture-negative, prosthetic valve endocarditis (early, ≤ 1 year)
  • 2. Pathogen-directed antimicrobial therapy
  • 2.1. Bartonella
  • 2.1.1. Suspected Bartonella endocarditis
  • 2.1.2 Documented Bartonella endocarditis
  • 2.3. Enterococcus
  • 2.3.1. Endocarditis caused by enterococcal strains susceptible to penicillin, gentamicin, and vancomycin
  • Preferred regimen : Ampicillin 12 g/24h IV q4h for 4–6 weeks OR Penicillin G 18–30 million U/24h IV either continuously or q4h for 4–6 weeks AND Gentamicin 3 mg/kg/24h IV/IM q8h for 4–6 weeks
  • Alternative regimen : Vancomycin 30 mg/kg/24h IV q12h for 6 weeks AND Gentamicin 3 mg/kg/24h IV/IM q8h for 6 weeks
  • Pediatric dose: Vancomycin 40 mg/kg/24h IV q8–12h; Gentamicin 3 mg/kg/24h IV/IM q8h
  • 2.3.2. Endocarditis caused by enterococcal strains susceptible to penicillin, streptomycin, and vancomycin and resistant to gentamicin
  • 2.3.3. Endocarditis caused by enterococcal strains resistant to penicillin and susceptible to aminoglycoside and vancomycin
  • β-Lactamase–producing strain
  • Intrinsic penicillin resistance
  • 2.3.4. Endocarditis caused by enterococcal strains resistant to penicillin, gentamicin, and vancomycin
  • Enterococcus faecium
  • Enterococcus faecalis
  • 2.4. HACEK organisms
