| Popis: | Background: Foot infections, a frequent complication of diabetes mellitus, are associated with heavy resource utilization, including antibiotic therapy and surgeries. However, the most common type of isolated pathogen in diabetic foot infections remains unknown. We aimed to identify the most common types of isolated pathogens in diabetic foot infections. Methods: This retrospective cohort study was conducted in a specialized medical center in Jeddah, Saudi Arabia. A total of 96 patients diagnosed with diabetes and presented with a foot ulcer showing clinical signs of infection were included. Results: The mean age was 63.03 ± 10.88 years, and 67.7% were males. The mean duration of diabetes diagnosis was 21.86 ± 9.66 years, and the majority had foot ulcers for over six weeks. Bacteria were present in 65 patients (67.7%), Gram-negative organisms were observed in 37 patients (38.5%), and Gram-positive organisms were present in 28 patients (29.2%). In the 65 patients with bacterial culture, Staphylococcus aureus was the most common isolated organism and was observed in 18 patients (27.7%), followed by Escherichia coli in 11 (16.9%) and Pseudomonas aeruginosa in 10 (15.4%). Binary regression analyses found that Gram-negative organisms were significantly more multidrug-resistant than Gram-positive organisms (P = 0.012, OR = 7.172, 95% CI = 1.542–33.352). Patient outcomes included healed ulcers (n = 10, 10.4%), minor amputation (n = 16, 16.7%), major amputation (n = 1, 1%), and debridement (n = 48, 50%). Conclusion: Gram-negative organisms were predominant in patients with diabetes and foot ulcers having clinical signs of infection. Treatment with an individualized antibiotic regimen is vital in ensuring optimal outcomes and preventing major amputations. |
