In addition, there was no association between incident infection and serum total or HDL-cholesterol concentrations or use of lipid-lowering agents including statins (P 0.21).DiscussionThe present study shows that type 2 diabetes is associated with a more 
than two-fold increase in the rate of hospitalization for any bacterial infection in representative patients from an urban community setting. One in five FDS1 type 2 patients was admitted with infection as a primary diagnosis during an average follow-up of 12 years compared with one in nine of the matched nondiabetic control subjects drawn from the same population over the same period. The distribution of the type of bacterial infection was similar in the two groups. Community-acquired pneumonia was the most common, accounting for approximately half of all admissions, but cellulitis, septicemia/bacteremia, osteomyelitis and genitourinary infections were also prominent causes. In the diabetic patients, independent associates of hospitalization with bacterial infection included older age, male sex, an infectionrelated admission before recruitment to FDS1, obesity, microangiopathy (retinopathy and albuminuria) and Aboriginal racial origin, but our data provide no evidence that statin therapy helps prevent hospital admission with infection, including pneumonia, in patients with type 2 diabetes. The IRR for hospitalization for any infection in our study (2.13) was similar to the relative risk of 2.17 for the same outcome in a large retrospective Canadian administrative database study of patients with diabetes of unspecified type and matched nondiabetic controls [4]. The distribution 
by type of bacterial infection was not significantly different between our FDS1 participants and the matched non-diabetic controls, consistent with the three most Sermorelin web common infections also being associated with an approximate doubling of the risk of hospitalization (with an IRR between 1.86 and 2.45 for pneumonia, cellulitis, and septicemia/bacteremia). Available published data support this finding. In a Dutch prospective general practice study, the adjusted odds ratios for medical attendances for the major specific 15755315 types of infection in patients with type 2 diabetes were all increased by 32 compared to control patients who had hypertension without diabetes [6]. For pneumonia, the relative risk of hospitalizationIndependent predictors of time to first incident infection in the diabetic patientsIn a Cox proportional hazards model (see Table 3), older age, male sex, higher BMI, higher urine ACR, retinopathy, Aboriginal racial background, and prior hospitalization for any infection (as principal diagnosis between January 1982 and FDS1 study entry) all increased the risk of hospitalization with any infection during follow-up (all P#0.006). After adjusting for these variables, statin therapy was not protective against hospitalization for any infection (hazard ratio (95 CI) 0.70 (0.39?.25), P = 0.22).
