Serum inflammatory markers, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cells (WBC), and procalcitonin (PCT), have been used for the diagnosis of foot infections in patients with diabetes. However, little is known about their changes during treatment of patients with foot infections. The aim of this prospective study was to examine the performance of serum inflammatory markers for the diagnosis and follow-up of patients with osteomyelitis. A total of 61 patients (age 63.1 ± 7.0 years, 45 men and 16 women, 7 with type 1 and 54 with type 2 diabetes) with untreated foot infection (34 with soft-tissue infection and 27 with osteomyelitis) were recruited. Diagnosis of osteomyelitis was based on clinical examination and was confirmed by imaging studies (X-ray, scintigraphy, magnetic resonance imaging). Determination of the inflammatory markers was performed at baseline, after 1 week, after 3 weeks, and after 3 months of treatment. At baseline, the values of CRP, ESR, WBC, and PCT were significantly higher in patients with osteomyelitis than in those with soft-tissue infections. The sensitivity and specificity for the diagnosis of osteomyelitis of CRP (cutoff value >14 mg/L) were 0.85 and 0.83, of ESR (cutoff value >67 mm/h) 0.84 and 0.75, of WBC (cutoff value >14 × 10(9)/L) 0.75 and 0.79, and of PCT (cutoff value >0.30 ng/mL) 0.81 and 0.71, respectively. All values declined after initiation of treatment with antibiotics; the WBC, CRP, and PCT values returned to near-normal levels at day 7, whereas the values of ESR remained high until month 3 only in patients with bone infection. From the inflammatory markers, ESR is recommended to be used for the follow-up of patients with osteomyelitis.

BackgroundThe aim of the present study is to examine the clinical indices related to cardiovascular risk management of Greek patients with type 2 diabetes, before and after the major economic crisis that emerged in the country.MethodsIn this retrospective database study, the medical records of patients with type 2 diabetes treated at three diabetes outpatient centers of the national health system during 2006 and 2012 were examined. Only patients with at least six months of follow-up prior to the recorded examination were included. The prescription cost was calculated in Euros per patient-year (€PY).ResultsA total of 1953 medical records (938 from 2006 and 1015 from 2012) were included. There were no significant differences in adjusted HbA1c, systolic blood pressure and HDL-C, while significant reductions were observed in LDL-C and triglycerides. In 2012, a higher proportion of patients were prescribed glucose-lowering, lipid-lowering and antihypertensive medications. Almost 4 out of 10 patients were prescribed the new incretin-based medications, while the use of older drugs, except for metformin, decreased. A significant increase in the adjusted glucose-lowering prescription cost (612.4 [586.5-638.2] €PY vs 390.7 [363.5-418.0]; p < 0.001) and total prescription cost (1306.7 [1264.6-1348.7] €PY vs 1122.3[1078.1-1166.5]; p < 0.001) was observed. The cost of antihypertensive prescriptions declined, while no difference was observed for lipid-lowering and antiplatelet agents.ConclusionsDuring the economic crisis, the cardiovascular risk indices of Greek patients with type 2 diabetes being followed in public outpatient diabetes clinics did not deteriorate and in the case of lipid profile improved. However, the total prescription cost increased, mainly due to the higher cost of glucose-lowering prescriptions.
