Short 3-week Antibiotic Treatment Versus 6 Weeks in Adults With Septic Arthritis of Native Joint
- Conditions
- Septic Arthritis
- Interventions
- Other: Short antibiotics treatment
- Registration Number
- NCT03716921
- Lead Sponsor
- Assistance Publique - Hôpitaux de Paris
- Brief Summary
In France, the incidence of native joint infections is about 10 per 100 000 person-years, most commonly caused by S.aureus followed by b-haemolytic streptococci. French and international antibiotic guidelines, based on expert advice and retrospective studies, recommend intravenous antibiotics for two weeks, then oral for 4 weeks without evident link between intravenous, prolonged oral treatment and cure. Long term exposure to antibiotics increases bacterial resistance, a major problem of public health. Several studies show that serious infectious can be treated safely by a shorter treatment and with oral antibiotics. There is no randomized controlled trial to establish the duration of antibiotics in native joint infections. Moreover, no consensus prevails on the administration route and duration of antimicrobial therapy. Although most clinicians acknowledge the interest of oral antibiotics and shorter treatment duration, randomized controlled trials are necessary to evaluate this practice. The SHASAR project aims to evaluate whether a shorter antibiotic treatment (3 week treatment) is safe and not inferior to the conventional 6 week treatment in native joint infections. If successful, this would represent a major advance in terms of patients' quality of life; decreased rate of health-care-related infections and complications, bacterial resistance and cost.
- Detailed Description
This trial is a nationwide, non inferiority, multicenter French randomized, open-label, controlled trial comparing two treatment durations, 3 versus 6 weeks, in septic arthritis of native joints. Patients who fulfill inclusion criteria will be randomized between day0 and day5. Day 0 is the time when effective intravenous antibiotic treatment is started. Effective treatment is defined by active antibiotics on the identified bacteria according to the susceptibility. The randomisation (1:1 ratio) will be stratified on early planned drainage. Follow-up will include 6 visits and will consist in clinical, biological, radiological, health quality of life (EQ-5D-3L score) and adverse events record. After collection, validation of data and population description, analysis will be conducted on the per-protocol population (patients receiving the planned duration of antibiotic +/-3days). This study will not be carried out blind for feasibility reasons. According to statistical considerations (by accounting for 5% of subjects lost to follow-up), the required sample size will be of 350 patients overall.

Group Intervention Description Short antibiotics treatment Short antibiotics treatment patients will receive effective antibiotic treatment (IV and oral) for 3 weeks
- Primary Outcome Measures
Name Time Method Cure at 16 weeks (4 months) after the beginning of the treatment 16 weeks after Day 0 Cure is defined as absence of clinical signs of joint infection, absence of treatment failure, absence of relapse
- Secondary Outcome Measures
Name Time Method Cure at 24 weeks 24 weeks after Day 0 Cure is defined as absence of clinical signs of joint infection, absence of treatment failure, absence of relapse
joint mobility at 16 and 24 weeks after Day 0 joint mobility is assessed by "good mobility, few mobility, no mobility"
Treatment failure and relapse and relapse rates 6,16,24 weeks after Day 0 % of relapse at 6,16,24 weeks
hospital length of stay and total treatments costs through study completion, an average of 3 years To compare cost-effectiveness and cost utility of 3-week vs 6-week antibiotic strategies for patients with arthritis of native joints
The patient's quality of life 3,6,16,24 weeks after Day 0 assessed by a quality of life questionnaire on 3,6,16,24 weeks. The EQ-5D-3L descriptive system comprises the following five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results into a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.
The residual joint pain in the affected joint at 16 and 24 weeks after Day 0 The residual joint pain is measured by a numerical scale. 0 means "no pain at all" and 10 "pain as bad as it could be".
