Introduction: Skin lesions represent lesions that result in loss of tissues and their joints and often this cutaneous process is a primary or secondary consequence of structural changes in the same skin surface. Type 2 diabetic subjects developing chronic skin lesions in the lower limbs in the western world are steadily increasing. We conducted a study on the etiologic incidence of chronic skin lesions in type II diabetic subjects in the lower limbs compared to subjects with chronic skin lesions (controls).
Materials and Methods: Thirty subjects (group "A") with Chronic Skin Lesions (CSL controls) (19 F-11M, mean age 67.5±7.2) in the lower limbs were admitted to our study according to a randomization scheme and compared a thirty (group “B”) type II diabetic patients (18F-12M, mean age 73.5±4.9) with chronic skin lesions (CSL). These two groups "A" and "B" have been studied and compared on the basis of infectious etiology responsible for the infectious skin process.
Result: In the subjects of the "A" group we found a positive bacteriological colony test of 9 examinations corresponding to the total 30.0%. In the group called "B" we obtained a colony test positive of 12 subjects over 30 corresponding to 40.0% of the examinations. For the number of bacterial species identified in the "A" group we obtained 7 monomicrobial and 2 poly microbial bacteriological tests, while in the "B" group we observed 3 mono microbial and 9 poly microbial tests. All bacteriological isolates showed "in vitro" sensitivity to satisfactory aminoglycosides with MICs range of 0.78- 1.56mg/L.
Conclusions: Data from this study show a different etiology among diabetic subjects than nondiabetic subjects. In fact, in the "B" group, more poly microbial bacteriological findings are found in positive culture studies with subjects in group "A". This phenomenon confirms an alteration of the skin microbiome of diabetic subjects with modification of the "opportunistic role" of some species of the skin bacterial flora.
