Abstract:
Objective To explore the risk factors of Pseudomonas aeruginosa infection in diabetic foot .Methods 136 patients with diabetic foot were divided into infection group (n=12) and control group(n=124) according to whether Pseudomonas aerugi-nosa infection existed .Their age ,gender ,body mass index (BMI) and complications were recorded ,and their hemoglobin ,fasting plasma glucose (FPG ) ,two hours postprandial blood glucose (2hPBG ) ,glycosylated hemoglobin A1c (GHbA1c) ,cholesterol , triglycerides ,low density lipid(LDL) ,high density lipid(HDL) ,serum albumin(SALB) were detected .Logistic regression analysis was employed to analyze the risk factors of Pseudomonas aeruginosa infection .Results Incidence of Pseudomonas aeruginosa infec-tion in diabetic foot was 8 .8% .Among them ,the infection incidences of elderly patients and patients with diabetic nephropathy were 11 .6% and 12 .7% ,respectively .Univariate analysis showed that male ,advanced age ,BMI ,duration of diabetes ,history of heart disease ,diabetic nephropathy ,FPG ,2hPBG ,GHbA1c ,low hemoglobin and low SALB were associated risk factors of Pseudomonas aeruginosa infection(P<0 .05) .After correction of confounding factors such as male ,BMI ,history of heart disease ,2hPBG and low hemoglobin ,advanced age ,duration of diabetes ,diabetic nephropathy ,GHbA1c and low SALB were independent risk factors for Pseudomonas aeruginosa infection(P<0 .05) .Conclusion Advanced age ,duration of diabetes ,diabetic nephropathy ,GHbA1c and low SALB are independent risk factors for Pseudomonas aeruginosa infection .
