  • Background: Hyperglycemia is known to impair host immune response by interfering with leukocyte migration and function. In this investigation, we sought to examine the differences in clinical presentation and outcome of patients with cardiovascular implantable electronic device (CIED) infection with and without diabetes mellitus. 

    Methods: We retrospectively reviewed all cases of CIED infection admitted to Mayo Clinic Rochester from January 1991 to December 2008. Clinical manifestations of CIED infection and prevalence of CIED-IE between patients with and without diabetes were compared using rank sum, chi-square and Fisher’s exact tests.


    Results: We identified 415 patients with CIED infection during the study period.  Of these, 115 (28%) of the patients had diabetes. As expected, patients with diabetes were more likely to have higher body mass index, renal insufficiency, coronary atherosclerosis and peripheral vascular disease. Patients with diabetes were more likely to present with blood stream infection (61% vs. 41%, p<0.001) compared to non-diabetics. Consequently, fever (50% vs. 37%, p=0.01) and chills (39% vs. 27%, p=0.02) were more common in patients with diabetes compared to non-diabetics, who were more likely to present with swelling (49% vs. 36%, p=0.01) and drainage (43% vs. 28%, p=0.005) from the generator pocket. Interestingly, diabetics had higher frequency of Staphylococcus aureus infection (39% vs. 28%, p=0.03) compared to non-diabetics. Patients with diabetes were also more likely to have distant metastatic foci on infection (10% vs. 3%, p=0.005). While 30-day survival between the two groups was similar, diabetics had poor long-term survival compared to non-diabetics (p=0.013).

    Conclusion: Patients with diabetes are more likely to present with systemic manifestations of CIED infection and associated complications compared to non-diabetics. However, short-term infection-related morality between the two groups is similar.
