From the Guidelines
Staphylococcus epidermidis line infections require prompt removal of the infected catheter and appropriate antibiotic therapy, with vancomycin being the recommended treatment for 10-14 days after catheter removal. The management of Staphylococcus epidermidis line infections involves several key considerations, including:
- Prompt removal of the infected catheter to prevent further infection and biofilm formation 1
- Appropriate antibiotic therapy, with vancomycin being the recommended treatment for uncomplicated infections 1
- Consideration of alternative antibiotics, such as daptomycin or linezolid, for patients with vancomycin allergies or MRSE (methicillin-resistant S. epidermidis) 1
- Obtaining blood cultures before starting antibiotics to confirm the diagnosis and guide therapy 1
- Prevention strategies, including strict adherence to sterile technique during catheter insertion, proper site care, and prompt removal of unnecessary catheters 1
In terms of specific treatment recommendations, the guidelines suggest that vancomycin 15-20 mg/kg IV every 8-12 hours (not to exceed 2g per dose) for 5-7 days after catheter removal, with a total treatment duration of 10-14 days for uncomplicated infections, is a reasonable approach 1. However, the treatment approach may need to be individualized based on the patient's clinical parameters and the presence of any complications, such as septic thrombosis or endocarditis 1.
It's also important to note that the management of CIED infections, including those caused by Staphylococcus epidermidis, requires a comprehensive approach that includes complete removal of all hardware, regardless of location, and appropriate antimicrobial therapy 1. The choice of antimicrobial agent should be based on identification and in vitro susceptibility testing results, and vancomycin should be administered initially as empirical antibiotic coverage until microbiological results are known 1.
Overall, the management of Staphylococcus epidermidis line infections requires a prompt and comprehensive approach that includes catheter removal, appropriate antibiotic therapy, and consideration of prevention strategies to reduce the risk of future infections.

From the Research
Staph Epidermidis Line Infection
- Staphylococcus epidermidis is often regarded as a culture contaminant, but its importance as a pathogen has been recognized in recent years 2.
- Most Staph. epidermidis infections are hospital-acquired, and it is a common cause of infections involving indwelling foreign devices, surgical wound infections, and bacteremia in immunocompromised patients 2.
- The occult nature of these infections and low virulence of the organism make diagnosis and treatment difficult 2.
Treatment Options
- Penicillin G, semisynthetic penicillinase-resistant penicillins, and cephalosporins are effective for the treatment of methicillin-sensitive Staph. epidermidis infections 2.
- Vancomycin is the drug of choice for infections caused by methicillin-resistant organisms, and it can be combined with rifampin or gentamicin for the treatment of serious infections caused by methicillin-resistant strains 2.
- Daptomycin shows a high efficacy against coagulase-negative staphylococci, including Staph. epidermidis, and it could be useful for the treatment of primary bacteremia or catheter-associated bacteremia 3, 4.
- Linezolid is also effective against Staph. epidermidis, but the massive and continuous use of linezolid has led to the appearance of resistance 3, 5.
Resistance Patterns
- Staph. epidermidis isolates from nosocomial infections frequently are resistant to methicillin, and cross-resistance between methicillin and cephalosporins occurs in vitro 2.
- Low susceptibility to vancomycin is frequent in coagulase-negative staphylococci, including Staph. epidermidis, and the rate of mecA positivity is high in these isolates 3, 6.
- Daptomycin and linezolid are effective against methicillin-resistant Staph. epidermidis, but resistance to these agents can also occur 3, 6, 5.
