Background and objectives: Type 2 diabetes (T2DM) is a risk factor for osteoporotic fractures and cardiovascular disease. The aims of our study were to evaluate serum Dickkopf-1(DKK1) levels in a cohort of T2DM patients and to analyze its relationships with bone metabolism and atheroesclerotic disease (AD). Patients and methods: We studied 126 subjects: T2DM patients (n: 72, mean age 58,2±6 years) and non-diabetic subjects (n: 54, mean age 55,4±7 years). DKK-1 was measured by enzyme-linked immunosorbent assay (ELISA, Biomedica Gruppe). Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry (DXA). The presence of AD (cerebrovascular disease, peripheral arterial disease, ischemic heart disease) was recorded. Intima-media thickness (IMT) was determined by doppler ultra- sonography and aortic calcification by evaluation of lateral view conventional X-rays. Results: We did not find significant differences in DKK1 between groups. Serum DKK1 concentrations were significantly higher in females in total sample (24,3±15,2 vs 19,6±10,2 pmol/L, p=0,046) and in T2DM group (27,5±17,2 vs 19,8±8,9 pmol/L, p=0,025). There was a positive correlation between serum DKK1 and LS BMD in total sample (r=0,183, p=0,048). However, we did not find a significant relationship with osteoporosis diagnosis or morphometric vertebral fractures. Serum DKK1 was significantly higher in T2DM patients with AD (26,4±14,5 pmol/L vs 19,1±11,6 pmol/L, p=0,026) and also in patients with abnormal IMT (26,4±15,1 pmol/L vs 19,8±11,3 pmol/L, p=0,038). In the ROC curve analysis to evaluate the usefulness of DKK-1 as a marker for high risk of AD, the area under the curve was 0,667 (95% confidence interval: 0,538-0,795; p=0,016). A concentration of 17,3 pmol/L or higher showed a sensitivity of 71,4% and a specificity of 60% to identify an increased risk of AD. Conclusions: Circulating DKK1 levels are higher in T2DM with AD and are associated with an abnormal IMT in this cross-sectional study. DK, Objetivos: La diabetes mellitus tipo 2 (DM2) se asocia a un incremento del riesgo de fracturas y de enfermedades cardiovasculares. Los objetivos de nuestro estudio fueron evaluar los niveles séricos de Dickkopf-1 (DKK1) en una cohorte de pacientes con DM2 y analizar su relación con el metabolismo óseo y la enfermedad ateroesclerótica (EA). Pacientes y métodos: Se estudiaron 126 sujetos: 72 pacientes con DM2 (edad media de 58,2±6 años) y 54 sujetos no diabéticos (edad media de 55,4±7 años). Se midió DKK1 mediante ensayo de inmunoabsorción ligado a enzimas (ELISA, Biomedica Gruppe), se determinó la densidad mineral ósea (DMO) mediante absorciometría dual de rayos X (DXA), se registró la presencia de EA (enfermedad cerebrovascular, enfermedad arterial periférica, cardiopatía isquémica) y se evaluó el grosor de la íntima-media (GIM, ultrasonografía doppler) y la calcificación aórtica (radiología simple). Resultados: No se encontraron diferencias significativas en DKK1 entre diabéticos y no diabéticos. Las concentraciones séricas de DKK1 fueron significativamente mayores en las mujeres de la muestra total (24,3±15,2 vs. 19,6±10,2 pmol/L, p=0,046) y del grupo DM2 (27,5±17,2 vs. 19,8±8,9 pmol/L, p=0,025). Hubo una correlación positiva entre DKK1 y DMO lumbar en la muestra total (r=0,183, p=0,048). Sin embargo, no se encontraron diferencias en función del diagnóstico de osteoporosis o presencia de fracturas vertebrales morfométricas. Los valores de DKK1 fueron significativamente mayores en los pacientes con DM2 y EA (26,4±14,5 pmol/L vs. 19,1±11,6 pmol/L, p=0,026) y también en pacientes con GIM anormal (26,4±15,1 pmol/L vs. 19,8±11,3 pmol/L, p=0,038). En el análisis de la curva ROC para evaluar la utilidad de DKK1 como un marcador de alto riesgo de EA, el área bajo la curva fue de 0,667 (intervalo de confianza -IC- del 95%: 0,538-0,795; p=0,016). Una concentración de 17,3 pmol/L o superior mostró una sensibilidad del 71,4% y una especificidad del 60% para identificar un may

Type 2 diabetes mellitus patients are at significant risk of cardiovascular disease, however, the pathophysiology of these complications is complex and incompletely known in this population. The aim of this study was to compare the serum proteome of patients with type 2 diabetes mellitus presenting or not presenting cardiovascular disease with non-diabetic subjects to find essential proteins related to these cardiovascular complications. This cross-sectional study compares the serum proteome by a combination of protein depletion with 2D-DIGE (2-dimension Difference Gel Electrophoresis) methodology. The proteins differentially expressed were identified by MALDI TOF/TOF (Matrix-assisted laser desorption/ionization and Time-Of-Flight ion detector) or LC-MS/MS (Liquid Chromatography coupled to Mass-Mass Spectrometry). Type 2 diabetes mellitus patients with cardiovascular disease showed higher expression of plasma retinol binding protein and glutathione peroxidase-3 compared to those without cardiovascular disease and non-diabetic controls. These results show that proteins related to the inflammatory and redox state appear to play an important role in the pathogenesis of the cardiovascular disease in the type 2 diabetes mellitus patients. © 2015 by the authors; licensee MDPI, Basel, Switzerland.
