Abstract:
The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and local wounds continues to be a major global public health concern. Evidence available for the selection of correct antiseptics for preventing and treating wound infections are limited. We here examined whether lysophosphatidylcholine (LPC) remains effective as a wound-compatible antiseptic against in vitro cultivated MRSA in the presence of an organic material. The antimicrobial efficacy of LPC against MRSA was investigated in the presence of various substances, namely bovine serum albumin, defibrinated sheep blood, mucin, and sodium hyaluronate, to evaluate the interactions between LPC and these compounds. We noted the inhibitory effects of 3 mL/L sheep blood and 3 g/L albumin, used to simulate a contaminated wound or environmental surface, on LPC. Two higher concentrations of hyaluronic acid (0.5 and 0.05 g/L) affected LPC activity against MRSA after 3 and 6 h of treatment. In the presence of four concentrations of mucin (30, 3, 0.3, and 0.03 g/L), LPC was almost ineffective against MRSA. We here provided information about interactions between several tissue-derived materials and LPC used against MRSA. In presence of some materials, LPC exhibited relatively stable antimicrobial effect. Thus, LPC may be a promising candidate as a wound antiseptic agent.
Insights
Lysophosphatidylcholine (LPC) shows potential as a wound antiseptic against methicillin-resistant Staphylococcus aureus (MRSA). Its effectiveness varies with organic materials found in wounds, with mucin significantly reducing its activity.
Area of Science:
- Microbiology and Infectious Diseases
- Dermatology and Wound Care
- Biochemistry and Biophysics
Background:
- Methicillin-resistant Staphylococcus aureus (MRSA) infections, including bacteremia and local wounds, pose a significant global health challenge.
- Limited evidence exists for selecting effective antiseptics for preventing and treating wound infections, necessitating research into novel agents.
Purpose of the Study:
- To evaluate the efficacy of lysophosphatidylcholine (LPC) as a wound-compatible antiseptic against in vitro cultivated MRSA.
- To investigate the interaction of LPC with organic materials commonly found in wound environments, such as albumin, blood, mucin, and hyaluronic acid.
Main Methods:
- Antimicrobial efficacy testing of LPC against MRSA in the presence of bovine serum albumin, defibrinated sheep blood, mucin, and sodium hyaluronate.
- Quantitative assessment of LPC's activity under simulated contaminated wound conditions at various concentrations and time points.
Main Results:
- Sheep blood (3 mL/L) and albumin (3 g/L) exhibited inhibitory effects on LPC's antimicrobial activity.
- Hyaluronic acid (0.5 and 0.05 g/L) impacted LPC efficacy against MRSA after 3 and 6 hours.
- Mucin significantly reduced LPC's effectiveness against MRSA across all tested concentrations (30-0.03 g/L).
Conclusions:
- Lysophosphatidylcholine (LPC) demonstrates a variable but potentially stable antimicrobial effect against MRSA in the presence of certain tissue-derived materials.
- The interaction of LPC with organic components like mucin can diminish its efficacy, highlighting the importance of formulation considerations.
- LPC warrants further investigation as a promising candidate for wound antiseptic applications, pending optimization for diverse wound environments.
