Brief Summary

Bone and joint infections (BJI) is a public health issue in industrialized countries. Implant-associated BJI, are complex hospital-acquired infections and eradication of the pathogen is challenging in such patients. A prolonged antimicrobial therapy is usually required from 6 weeks to 3 months, but some patients are eligible to several years of treatment and most of patients report gastrointestinal troubles, such as nausea and mild to severe diarrhea (but very few developed C. difficile diarrhea). Moreover, the host gut microbiota is probably largely affected in abundance, richness and diversity. Indeed, it is known, that few days of antibiotics are sufficient to induce significant alterations of the gut microbiota, also called dysbiosis. Severe dysbiosis, which is potentially irreversible and associated with a definitive shift in the gut microbiota metabolism and host homeostasis, may lead to and/or promote a large panel of severe diseases such as Clostridium difficile infection, diabetes mellitus, obesity, inflammatory bowel disease (IBD), cirrhosis, neurological disorders and cancer. It may also be associated with BJI recurrence and then impact global health costs. The main objective of this study is to constitute biobanking of stools and perform DNA sequencing of the gut microbiota in patients with acute or sub-acute implant-related Bone and Joint Infection (BJI), caused by Staphylococcus aureus.

Outcome Measures

Primary Outcomes (1)

  • change in the gut microbiota after treatment

    stools will be collected to perform DNA sequencing of the gut microbiota in patients with acute or sub-acute implant-related Bone and Joint Infection (BJI), caused by Staphylococcus aureus. Stools will be collected at baseline, during antibiotic treatment (Week 2), at the end of treatment (Week 6 or Week 24),15 days after antibiotherapy stop (Week 8 or Week 26), and W26 after baseline.

    from baseline to week 26

Secondary Outcomes (8)

  • Assessment of the evolution of intensity of Diarrheic Symptoms

    from baseline to week 8 or week 26

  • Assessment of the evolution of frequency of Diarrheic Symptoms

    from baseline to week 8 or week 26

  • Quantity of rectal acquisition of Multi Drug Resistance (MDR) bacteria under antibiotics measured by classic culture and quantification culture methods

    at week 6 or week 24

  • gut dysbiosis measured by Next Generation Sequencing (NGS)

    from baseline to week 26

  • severe post-antibiotic dysbiosis (SPAD) measured by Next Generation Sequencing (NGS)

    from baseline to week 26

  • +3 more secondary outcomes

Study Arms (1)

Patients treated by antibiotherapy

EXPERIMENTAL

35 Patients treated by antibiotherapy for acute and subacute post-operative implant-associated BJI infections and among them 10 patients with Staphylococcus. aureus treated with antibiotics as part of their standard treatment procedure for metagenomic procedure.

Biological: Patients treated by antibiotherapy

Interventions

Biological samples (stool, blood, swabs) will be collected : * Blood sampling (12 ml) at baseline (week 0) at the end of treatment (W6/W24),and 15 days after antibiotherapy stop (optional) (W8/W26), * Feces collection at baseline (week 0) during antibiotic treatment (W2), at the end of treatment (W6/W24),15 days after antibiotherapy stop (W8/W26), and W26 after baseline * Swab samples (nasal and rectal) at baseline at week 0 and at the end of treatment (W6/W24),
