Official title
Osteoarticular Infections on Equipment: Impact of Three Probabilistic Antibiotic Therapy on Digestive Microbiota and Colonization With Multi-resistant Bacteria
Overview
In the event of suspected osteoarticular material infection (OAMI), broad-spectrum probabilistic antibiotic therapy is recommended immediately after revision surgery. There are no efficacy data to suggest that any particular to favour any particular molecule. However, the choice may depend on the impact on the microbiota and on Enterobacteriaceae colonization with multi-resistant Enterobacteriaceae. Our aim is to evaluate three different strategies efepime+daptomycin C+D, piperacillin-tazobactam+daptomycin (PT+D) and ceftobiprole (CFB).
Interventions
- Other Stool sample 1
Stool sampling at D0 for having baseline reference - Other Stool sample 2
Stool sampling at D5 to study the impact of antibiotics on microbiota - Other Stool sample 3
Stool sampling at DX+28 to study the impact of antibiotics on microbiota
Primary outcome measures
- Compare changes in gut microbiota biodiversity between Day1 and Day5 between populations treated with C+D, PT+D and CFB in suspected Osteoarticular infection on equipment [Time frame: At Day 5 after starting treatment]
Secondary outcome measures (6)
- Compare the evolution between Day1/end of treatment+28 Days and between Day 5/end of treatment+28D of microbiota biodiversity of each patient population treated with different antibiotics for suspected Osteoarticular infection on equipment [Time frame: Up to 4 months]
- Compare the rate of acquisition of multidrug-resistant extended-spectrum beta-lactamase-producing intestinal Enterobacteria between antibiotic strategies on samples at Day5 and DX+28 in patients with no multidrug-resistant Enterobacteria at Day1. [Time frame: Up to 4 months]
- Compare the rate of acquisition of carbapenemase-producing intestinal multi-resistant Enterobacteriaceae (EPC) between antibiotic strategies on samples taken at D5 and DX+28 in patients with no multi-resistant Enterobacteria at D1. [Time frame: Up to 4 months]
- Comparison of the rate of inadequacy of probabilistic strategies in the event of retained infection. [Time frame: Up to 4 months]
- Compare the evolution between J5/JX+28 of microbiota biodiversity of patients receiving no antibiotic treatment for infection and patients in whom an infection is detected, with antibiotic treatment prescribed for 6 to 12 weeks. [Time frame: Up to 4 months]
- Compare the evolution between J5/JX+28 of microbiota biodiversity of patients receiving no antibiotic treatment for infection and patients in whom an infection is detected, with antibiotic treatment prescribed for 6 to 12 weeks. [Time frame: Up to 4 months]
