Study Details

Study Description

Brief Summary

The incidence of bone and joint infections (BJI) in children (osteomyelitis, septic arthritis and spondylodiscitis) is 22 per 100,000 children in France. Every year, 3,000 children are hospitalized for BJI, 46% of whom are hospitalized for osteomyelitis. The clinical pictures of BJI are varied: some are severe from the outset; others are non-severe, such as BJIs in Kingella kingae, which are most common in children between the ages of 6 months and 5 years. Currently, the management of children's BJI, regardless of their severity, involves initial hospitalization to start intravenous antibiotic therapy. This non-inferiority trial evaluates, in children with acute osteomyelitis with no severity criteria, less invasive outpatient management with an oral antibiotic treatment given at the outset compared to standard management.

Main objective : Demonstrate the non-inferiority of an ambulatory management strategy versus a standard strategy involving hospitalization on complete recovery without relapse at 6 months after an episode of acute osteomyelitis in children aged 1-4 years without severity criteria.

Primary endpoint: Complete cure without relapse at 6 months defined by the absence of clinical signs of osteomyelitis at 6 months AND the absence of secondary septic complications (septic arthritis, periosteal abscess) before the end of antibiotic therapy AND the absence of relapse or rehospitalization for osteomyelitis related to the initial infection. This criterion will be assessed blindly by an adjudication committee.

Randomized controlled trial of non inferiority, with active control, in open multi-center.

The control or experimental arm allocation (1:1 ratio) will be open-label of the physician, patient and parents. This is a PROBE study: The evaluation of the main judgment criterion will be carried out blindly by an adjudication committee.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Intravenous antibiotic treatment

Intravenous antibiotic treatment started during an initial hospitalization of 3 days, with continuation of oral antibiotic therapy at home for a total duration of antibiotic therapy of 3 weeks

Other: therapeutic strategy
Outpatient management strategy of acute non-severe osteomyelitis in children with oral antibiotic therapy compared to a standard strategy with conventional hospitalization and intravenous antibiotic therapy

Experimental: oral antibiotic treatment

Oral antibiotic treatment started in hospital then continued at home for a total duration of 3 weeks of antibiotic therapy

Other: therapeutic strategy
Outpatient management strategy of acute non-severe osteomyelitis in children with oral antibiotic therapy compared to a standard strategy with conventional hospitalization and intravenous antibiotic therapy

Outcome Measures

Primary Outcome Measures

  1. Complete recovery without relapse at 6 months [6 months]

    Complete recovery without relapse defined by the absence of clinical signs of osteomyelitis (absence of pain, fever, swelling & heat of any limb, biological inflammatory signs, relapse or hospitalisation AND the absence of secondary septic complications (septic arthritis, sub-periosteal abscess)
