Description

Inclusion Criteria:

  • diabetic patients treated non-surgically (i.e. without amputation or resection of the infected bone) for an osteomyelitis of the foot complicating a neuropathic foot without ischemia of the foot defined as the absence of any pedal pulse. Patients aged of 18 years or more were included if they had type 2 diabetes and osteomyelitis of the foot (i.e.below the ankle).

Exclusion Criteria:

  • Patients with gangrene or who require bone resection or amputation when osteomyelitis of the foot was diagnosed

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Primary outcome measure was the proportion of patients of each group with remission of diabetic foot osteomyelitis at the end of follow-up.
Time Frame: one year
Remission was defined as the absence of any sign of infection at the initial or a contiguous site, evaluated at least one year after the end of antibiotic treatment (ie at the end of follow-up), with neither a new infectious episode nor the need for orthopedic surgery of the foot at either of these sites during the treatment and follow-up period.
one year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
tolerance to treatment in each group of patients
Time Frame: 6 or 12 weeks
number of episodes of adverse events attributable to the antibiotic treatment recorded in each group of patients.
6 or 12 weeks
