Role of inflammatory markers in the healing time of diabetic foot osteomyelitis treated by surgery or antibiotics

OBJECTIVE: To analyse the predictive role of inflammatory markers in the healing time of diabetic foot osteomyelitis treated by surgery or antibiotics. METHODS: An observational study of patients with diabetic foot ulcers (DFU) and clinically suspected osteomyelitis. The patients underwent surgical or antibiotic treatment for bone infection in a specialised diabetic foot unit. Blood samples were taken from each patient to analyse biomarkers. The main outcome was the number of weeks until healing occurred. RESULTS: A total of 116 patients took part in the study. The number of weeks until healing was similar for both groups (surgical n=96 and antiobiotic n=20, treatments). No association was observed among biomarkers as predictors of time-to-healing. CONCLUSION: There is not enough evidence to define the prognostic role of inflammatory markers in the healing time of DFUs complicated with diabetic foot osteomyelitis, regardless of the treatment administered.
