Sharp Healthcare System Treatment Guidelines for Skin Infections Take-Home Points 1) Most skin infections are caused by Staph and Strep -Anaerobic and gram negative coverage (i.e. Anaerobic bacteria are the predominant flora in the normal human skin and mucous membranes and are, therefore, a common cause of endogenous infections. Anaerobic coverage is indicated in a variety of infectious processes, including but not limited to aspiration pneumonia, intra-abdominal infection, gynecologic infection, and ... or a combination of cefepime plus metronidazole. coverage for Enterococcus or Pseudomonas. If cultures become positive for Gram positive cocci in chains substitute daptomycin 6 mg/kg IV daily for the vancomycin. Metronidazole has been associated with neurotoxicity and may be co-administered with cefepime to provide additional anaerobic coverage. Cefepime. Anaerobic infections are caused by anaerobic bacteria. Data sources include IBM Watson Micromedex (updated 2 Feb 2021), Cerner Multum™ (updated 3 Feb 2021), ASHP … This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. No allergy to penicillin or cephalosporin start cefepime 2 g IV q8h plus vancomycin 15 mg/kg IV q12h plus tobramycin 5 mg/kg IV q24h (adjusted weight). Adjust antibiotic coverage based on culture and sensitivity. streptococcal coverage plus obligate anaerobic bacilli coverage for distal small bowel, appendiceal, and colon-derived infection and for more proximal gastrointestinal perforations accompanied by obstruction or paralytic ileus Aerobic and facultative Gram negative bacilli, enteric streptococci, and Bacteroides and other anaerobes are KEY PONTS Cefazolin (Ancef) is an injectable first-generation cephalosporin and beta-lactam antibiotic that interferes with bacterial cell wall synthesis in sensitive organisms Has activity versus some Gram positive organisms (e.g., Strep. Cefepime is a bactericidal drug that acts by inhibition of bacterial cell wall synthesis. 29 Zidebactam demonstrates its β-lactam activity by binding to PBP2 of Enterobacterales, P. aeruginosa and Acinetobacter baumannii. Sulfonamides, fluoroquinolones, and macrolides have been associated with psychosis as well [9]. ... (Resistance is increasing) & Levofloxacin. Anaerobic organisms ... • Metronidazole PLUS cefepime or ciprofloxacin ... Anaerobic coverage is not mandatory unless there is a biliary-enteric Cefepime (4th Gen Cephalosporin). This would be consistent with the potential ADR of lowering seizure- Empiric coverage for Candida is not recommended For diverticular abscess, consult surgery or interventional radiology for aspiration and drainage Patients with low/medium-risk allergy2 to penicillins and cephalosporins other than cefepime, ceftriaxone, cefpodoxime, and cefotaxime can receive cefepime Take a look at the recommendation: Reading this recommendation, it is not clear whether the guideline is suggesting metronidazole be added to the other anaerobic agents or only to ceftazidime or cefepime. • Anaerobic coverage is not routinely warranted in non-critically ill patients with aspiration pneumonia. The regimens for Zidebactam (WCK 5107) is a new diazabicyclooctane (DBO) BLI with intrinsic β-lactam activity. Limited anaerobic coverage. o Treat with regimens for hospital-acquired pneumonia (HAP) (e.g., cefepime, piperacillin-tazobactam) if the event occurred 72 hours after admission to a health care facility. Anaerobic coverage should be provided when imaging findings (CXR or CT) suggest lung abscess or empyema. No anaerobic coverage. Our goals were to identify risk factors for cefepime-resistant P. aeruginosa infections in the hospital setting and to describe 29 Its inhibitory spectrum covers class A, class C and some class D β-lactamases (Table 3). (ISBN: 978-0 … Similarly, most anaerobic bacteria remain susceptible to o Reassess at 48 hours. Vancomycin may be added if MRSA is a concern. Quick reminder Cefepime = ceftriaxone + pseudomonas coverage Tazocin (pip/tazo) = cefepime + anaerobic coverage Meropenem = Tazocin + ESBL coverage Ertapenem = Meropenem - pseudomonas coverage Metronidazole can be added to ensure anaerobic organism coverage. As a fourth generation cephalosporin, cefepime covers many gram positive and gram … GI: Appendectomy. Anti-Pseudomonal (including ceftazidime resistant isolates) Penetrates CSF. ** Cipro and levofloxacin still provide excellent coverage for Pseudomonas, especially after I.D. Jones & Bartlett Publishers, Sudbury MA. Obligately anaerobic bacteria do not grow on solid media in room air (0.04% carbon dioxide and 21% oxygen); facultatively anaerobic bacteria can grow in the presence or absence of air. ID should be consulted in cases of Healthcare-associated pneumonia (HCAP) ... Cefepime 2 g q8h 3) Ceftazidime 2 g q8h 4) Aztreonam 2 g q8h 5) Meropenem 1 g q8h 6) Imipenem 500 mg q6h. Cefepime is a fourth-generation cephalosporin antibiotic.Cefepime has an extended spectrum of activity against Gram-positive and Gram-negative bacteria, with greater activity against both types of organism than third-generation agents.A 2007 meta-analysis suggested when data of trials were combined, mortality was increased in people treated with cefepime compared with other β-lactam antibiotics. Cefepime neurotoxicity is not widely recognized by clinicians. Coverage for methicillin- resistant ... o It is not necessary to add additional anaerobic or atypical coverage. Since anaerobic infections are generally polymicrobial, where anaerobes are mixed with aerobic organisms, therapy should provide coverage of … Strong recommendation, moderate quality of evidence. Cefepime is used for bacterial infections caused by microorganisms that are sensitive to drugs in septicemia, bacteriemia, complicated infections of the upper and lower sections of the urinary system, pneumonia, pulmonary abscesses, emphysema of the pleura, fever in patients with neutropenia, and infected skin and soft tissue wounds. ; no anaerobic coverage . Good gram-positive & gram-negative coverage. Gram Positive Cocci (GPC) Gram Neg (rods = GNR) Anaerobes Atypicals Classification Antibiotic Cluster = Staph Streptococcus β↓ & α-hemolytic↓ Entero- Cefepime is categorised as a fourth-generation cephalosporin because it shows a broader spectrum of activity than third-generation cephalosporins such as ceftazidime . Cefepime should be considered only in non-severe infections (eg, uncomplicated urinary tract infection) when the minimum inhibitory concentration (MIC) is 2 mg/L or less (1). Intra-abdominal Infections, including peritonitis caused by E. coli, Klebsiella spp., and polymicrobial infections caused by aerobic and anaerobic organisms (in combination with metronidazole) Central nervous system infections including meningitis, caused by H. influenzae, N. meningitidis, and P. aeruginosa Cefepime has a broad spectrum of in vitro activity that encompasses a wide range of Gram-positive and Gram-negative bacteria. nosis of Asp received anaerobic antibiotics (18/20). Furthermore, it is unlikely that a pathogen resistant to a broad-spectrum beta-lactam, like cefepime, will remain susceptible to a fluoroquinolone. - th4 generation (cefepime) has expanded gram negative coverage including pseudomonas spp. Within bacterial cells, the molecular targets of Cefepime … Preferred over gentamicin in cases with HIE N=1 have observed hypertension, seizure-like, dystonic activity when cefepime was given intraperitoneal in PD fluid while also receiving Zosyn. The following day, the patient’s antibiotic regimen was changed from cefepime to piper- acillin/tazobactam for additional anaerobic coverage as fever and leukocytosis remained present and no source had been identified. Anyone reading the IDSA guidelines for intra-abdominal infections might be led to believe that double anaerobic coverage is indicated. pathogens remain susceptible to cefepime, then empiric gram-negative double coverage is not necessary under most circumstances. Other cephalosporins and penicillins have been associated with seizures and delirium [9, 15]. Metronidazole can be added to ensure anaerobic organism coverage. Zosyn, ceftriaxone or levo/cipro) is NOT needed in most cases 2) Treatment duration is 5 days with clinical response Microaerophilic bacteria do not grow at all aerobically or grow poorly, but grow better under 10% carbon dioxide or anaerobically. 2010 2nd Edition. First Generation Cephalexin (po – Keflex) Useful in cellulitis, osteomyelitis; alternative for UTI Cefazolin (IV – Ancef, Kefzol) Useful in surgical prophylaxis If the patient has a severe beta-lactam allergy, alternative options for Gram-negative coverage in sepsis include: Aztreonam, Ciprofloxacin or Levofloxacin, and Aminoglycosides. Cefepime (Maxipime) is a powerful, broad-spectrum intravenous antibiotic commonly used in the inpatient and intensive care unit (ICU) settings to treat a myriad of infections. To date, clinical studies comparing cefepime vs carbapenem have been small and/or retrospective, often with conflicting results (1). Cefepime was not associated with adverse developmental outcomes in rats, mice, or rabbits when administered parenterally during period of organogenesis; the doses used in these studies were 1.6 times (rats), approximately equal to (mice) and 0.3 times (rabbits) the maximum recommended clinical dose There is typically a delay of 3 to 5 days between onset of symptoms and diagnosis, as illustrated by our patient. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. 3 (especially B fragilis) and . You can use them po. • Anaerobic coverage may be appropriate in patients with cavitary or necrotizing pneumonia, empyema, complicated parapneumonic effusion, lung abscess, or post-obstructive pneumonia. Anaerobic coverage (cefoxitin, Cefotetan, Cefmetazole) Intra-abdominal Infections Lung Infections (CAP), Meningitis, Pyelonephritis (UTI that has progressed to involved the kidneys) 4. However, a significant proportion of patients with CAP and HCAP also received anaerobic antibiotics (17% and 28%, respectively) (Table 1). Cefepime. Cefepime. resistance to cefepime among these organisms has been noted (14–18). Both cefepime and ceftazidime demonstrate activity against Gram-positive organisms whilst retaining expanded Gram-negative coverage. Regardless of pneumonia type, 180 patients did not meet the criteria for anaero-bic antibiotic coverage as defined in the methodology, 2. 2 If consulted for encephalopathy or coma, the clinician should consider cefepime as a possible culprit when reviewing the medication list. and sensitivities are back. Bartlett JG, Auwaerter PG, Pham PA (2010): The Johns Hopkins ABX Guide.Diagnosis and Treatment of Infectious Diseases. 3. •Anaerobic coverage ... extended antibiotic coverage in adults with CAP. 30–33 Cefepime primarily targets … Cefepime/zidebactam. 3. As such, elucidating the epidemiology of cefepime-resistant P. aeruginosa is crucial to ensure that this agent remains a viable therapeutic option. -Cefepime can be use d for CNS infections and readily achieves therapeutic concentrations in the lungs.
