Comparison Between Two Durations of Antibiotherapy for Non-surgically-treated Diabetic Foot Osteomyelitis (CHRONOS-2) (CHRONOS-2)

Detailed Description
The fight against multi-drug resistant bacteria is a global matter and a major health public issue. The excessive exposure of microorganisms to drugs increases their ability to develop survival mechanisms, causing an emerging threat and a health challenge.
Several recent studies showed that 18-35% of patients with diabetic foot infections harbored multiply drug-resistance to organisms (MDRO), the most common is Staphylococcus aureus (MRSA). Hospitalization, surgical procedures and long antibiotic therapy induce the development of MDRO or MRSA In diabetic foot, Osteomyelitis (DFO) is a well recognize risk factor for major amputation and mortality rates that occurs in more than 20% of moderate infections and 50% to 60 % of severe infections. In this context, the aim of this study is to evaluated that reducing time of antibiotic administration (3 weeks) is not substantially worse than the current treatment guidelines (6 weeks) in DFO managed nonsurgically.
