Summary

The Infectious Diseases Society of America (IDSA) 2012 guidelines for the diagnosis and treatment of diabetic foot infections state that for the treatment of diabetic foot osteomyelitis "No data support the superiority of any specific antibiotic agent or treatment strategy, route, or duration of therapy." Traditionally, osteomyelitis has been treated with a long course of intravenous antibiotics, generally six weeks. Oral antibiotics with high bioavailability and adequate bone penetration have been shown in published studies to be effective for the treatment of osteomyelitis.

The investigators propose to conduct a prospective, single-center, randomized, open trial at Loyola University Medical Center (LUMC) comparing the efficacy of oral antibiotic therapy to intravenous (IV) antibiotic therapy for the treatment of diabetic foot osteomyelitis. The investigators hypothesize that oral antibiotic therapy is equivalent to IV antibiotic therapy. Bone/tissue cultures are obtained for all patients for clinical purposes and are sent to pathology for histologic examination and to the clinical microbiology laboratory for culture and susceptibility. Patients will receive six weeks of IV or oral antibiotic therapy depending upon their randomization group. Primary outcomes at six months clinical follow-up will include: (i) no evidence of bone infection and (ii) resolution of ulcer.

Interventions

DRUG

Intravenous Antibacterial Agent

Individuals in this arm receive an intravenous antibacterial agent. They are not assigned to specific medications. Individuals in this arm will receive an intravenous antibacterial agent as determined by their primary healthcare provider. This therapy is usually one of the following intravenous medications: (i) piperacillin/tazobactam (Zosyn), (ii) cefepime, (iii) metronidazole, (iv) aztreonam, (v) vancomycin, (vi) daptomycin, (vii) linezolid (Zyvox), and/or (viii) meropenem.

DRUG

Oral Antibacterial Agent

Individuals in this arm receive an oral antibacterial agent. They are not assigned to specific medications. Individuals in this arm will receive an oral antibacterial agent as determined by their primary healthcare provider. This therapy is usually one of the following oral medications: (i) sulfamethoxazole/trimethoprim (SMX-TMP), (ii) clindamycin (Clindesse), (iii) linezolid (Zyvox), (iv) moxifloxacin (Avelox), (v) ciprofloxacin (Cetraxal), and/or (vi) metronidazole (Flagyl)
