To describe the microbiological profile and clinical outcomes of diabetic foot ulcers of inpatients of a tertiary university hospital, at Ceara, Brazil. Methods: We conducted a retrospective analysis of medical charts data of all diabetic inpatients of the Endocrine and Diabetes Unit of Walter Cantídio University Hospital (Federal University of Ceará), admitted from January, 2006 to June, 2007 for severe foot ulcers (minimum of grade 2 of Wagner`s classification), which were refractory to ambulatory treatment. Clinical data from each patient were recorded (sex, age, diabetes duration, and comorbidities) as well as microbiological characteristics of foot ulcers and surgical (amputations) material. Results: We identified 17 diabetic patients, all type 2, aged 58.11 ± 10.8 years and 12.4 ± 8.4 years of disease, 58.8% male. Of ulcers, 41.1% were grade 2; 35.2% grade 3; 11.7% grade 4 and 11.7% grade 5 of Wagner; 64.7% with less than 3 months of evolution. Debridement was performed in 82.3% of patients and amputation in 47%; osteomyelitis was identified in 47% of cases. All patients started empiric antibiotic therapy, where ciprofloxacin/metronidazole was the most used scheme (76.5%). Cultures were negative in 12.5% of the patients. In the positive ones, the most prevalent bacterial pathogens detected in the culture materials were: S. aureus (57.1%); S. viridans (28.7%); P. aeruginosas (28.7%); M. morganii (28.7%). The majority (75%) of isolated S. aureus were methicillin-resistant, but were sensitive to vacomicin. Conclusion: We observed the presence of polymicrobial flora with a large number of multiresistant pathogens and high prevalence of osteomyelitis and amputations in diabetic patients with severe ulcers, neuropathy and peripheral vascular disease.
