Abstract:
The aim of the present study was to determine whether treatment with polymyxin B-immobilized fibre (PMX-F) haemoperfusion, teicoplanin, or both in combination is effective in patients with methicillin-resistant Staphylococcus aureus (MRSA) sepsis. Sixty patients with MRSA sepsis were randomly assigned to one of four treatments: (A) PMX-F treatment (N=15), (B) teicoplanin treatment (N=15), (C) PMX-F and teicoplanin in combination (N=20) and (D) conventional therapy (N=10). PMX-F treatment was repeated twice. Teicoplanin was administered by intravenous injection. Plasma endotoxin levels were determined by endospecy test. Plasma endotoxin levels were reduced in groups A and C (P<0.05). Survival rates were 53, 47, 90, and 20% in groups A, B, C and D, respectively (group C versus group A, P<0.05; group C versus group B, P<0.01; group C versus group D,P <0.001). The mean duration of stay was 44, 42, 28 and 56 days in groups A, B, C and D, respectively. Our data suggest that combination therapy with PMX-F and teicoplanin is effective for sepsis caused by MRSA.
Insights
Combination therapy using polymyxin B-immobilized fiber (PMX-F) and teicoplanin significantly improves survival rates in patients with methicillin-resistant Staphylococcus aureus (MRSA) sepsis.
Area of Science:
- Infectious Diseases
- Critical Care Medicine
- Pharmacology
Background:
- Methicillin-resistant Staphylococcus aureus (MRSA) sepsis poses a significant threat with high mortality rates.
- Conventional therapies for MRSA sepsis have limitations in improving patient outcomes.
Purpose of the Study:
- To evaluate the efficacy of polymyxin B-immobilized fiber (PMX-F) hemoperfusion, teicoplanin, and their combination in treating MRSA sepsis.
- To compare the effectiveness of these treatments against conventional therapy.
Main Methods:
- A randomized study involving 60 patients with MRSA sepsis assigned to four groups: PMX-F, teicoplanin, combination therapy, and conventional therapy.
- PMX-F treatment was administered twice, while teicoplanin was given intravenously.
- Plasma endotoxin levels were measured, and survival rates and duration of hospital stay were recorded.
Main Results:
- Combination therapy (PMX-F and teicoplanin) resulted in a significantly higher survival rate (90%) compared to PMX-F alone (53%), teicoplanin alone (47%), and conventional therapy (20%).
- Plasma endotoxin levels were reduced in patients treated with PMX-F (groups A and C).
- The combination therapy group also showed a reduced mean duration of hospital stay (28 days).
Conclusions:
- Combination therapy with PMX-F and teicoplanin is highly effective in treating MRSA sepsis.
- This combined approach offers a promising strategy to improve survival and reduce hospital stay in patients with MRSA sepsis.
