Abstract:
Objective:To analyze the impact of rare bacteria infection on clinical outcome in patients with diabetic foot ulcer(DFU).Methods:A total of 288 cases infected with single strains bacteria were selected. Data were grouped according to the 15 bacteria infection identified. The outcomes of healing, amputation, cardio and cerebrovascular events, and death were collected, and risk factors to the outcome were analyzed.Results:The rare infected bacteria were acinetobacter baumannii, staphylococcus epidermidis, morgan morganella, staphylococcus haemolyticus, streptococcus lactis, streptococcus agalactiae, enterobacter cloacae, and serratia marcescens.There were significant differences in age, albumin, HbA 1C, body mass index, condition of foot ulcer, degree of infection, healing, and minor amputation among these groups. Severe lower extremity arterial disease and age over 70 years were the main risk factors for the healing of ulcers. Wagner grade over 3 and infected with streptococcus lactis were the main risk factors for minor amputation. Severe lower extremity arterial disease, hemoglobin(Hb)≤90 g/L, and albumin(ALB)≤30 g/L were the main risk factors for major amputation. Estimated glomerular filtration rate <60 ml·min -1·(1.73 m 2) -1 and Hb≤90 g/L were the main risk factors for heart failure. Age over 70 years and ALB≤30 g/L were the main risk factors for death(All P<0.05). Conclusion:There exist significant differences in general condition, foot ulcer, and outcome in DFU patients infected with rare bacteria strains.
