ABSTRACT

Objective: To investigate the bacterial etiology and the most frequent resistance in infections of diabetic foot in our hospital.
Methods: The bacterial resistance, the most frequent microorganism, complications and mortality in patients was described in hospitalized patients with lesions of diabetic foot, from March 2004 to April 2007. The variables were analyzed statistically.
Results: 79 patients were included, 26 (32.9%) female and 53 (67.1%) male, the age was 61.93 ± 11.16 years. Showed lesions Wagner II in 11 (13.9%) patient, III in 36 (45.6%) and IV in 32 (40.5%). The minor amputations were carried out to 41 patients (51.9%) and major at 11 (13.9%). The laboratory results were: lymphocytes 17.05% ± 9.46% and creatinine of 2.8 ± 2.92 mg/dl.
105 bacterials were reported; the most frequent Staphylococcus aureus 21 (27.3%), Escherichia coli 14 (13.33%) and Staphylococcus epidermidis 12 (11.42%), also the most resistant respectively. The resistant to the empiric therapy were 53 (50.47%) and in the antibiogram 65 (61.9%) to more than 2 different antibiotics. 12 were presented (15.6%) reinfections and 1 (1.3%) death.
Conclusions: The most resistant antibiotic in the empiric therapy was ciprofloxacin. We suggest an empiric treatment of a cephalosporine of third generation and clindamycin. It was low mortality (1.3%) and fewer amputations (13.9%) that reported in the literature. The lesion Wagner IV and the failure renal are associated significatively with major amputation. The lymphopenia presence, high creatinine and lesion Wagner IV were related with more bacterial resistance.
