    الوصف: Objetivo: Nuestro estudio tiene como objetivo principal valorar la evolución de los niveles de esclerostina en pacientes con trasplante hepático, e investigar su relación con otros marcadores de remodelado óseo. Material y método: Estudio observacional prospectivo. Se incluyeron 83 pacientes con trasplante hepático. Se determinaron los valores de esclerostina, β-crosslaps, fosfatasa alcalina ósea, osteocalcina y proteína C reactiva la semana anterior al trasplante y posteriormente, a los 1, 3, 6 y 12 meses. Se determinaron basalmente la 25 hidroxi-vitamina D y la paratohormona. En cada revisión se evaluó la existencia de fracturas. La evolución de los marcadores respecto del valor basal se determinó mediante la prueba t-Student. Un valor de p inferior a 0,05 se consideró estadísticamente significativo. Resultados: 56 varones y 27 mujeres (edad media: 56,2±10,4 años). Los niveles basales de esclerostina (0,76±0,35 ng/ml) disminuyeron de forma significativa precozmente (0,55±0,22 ng/ml en el primer mes, p=0,034), tendencia que se mantuvo hasta los 12 meses (0,62±0,22 ng/ml, p=0,047). Al contrario, los niveles basales de osteocalcina (17±10,3 ng/ml) y β-crosslaps (0,44±0,3 ng/ml) se incrementaron significativamente a los largo del estudio; en el caso de la osteocalcina, hasta los 12 meses (37,27±26,84 ng/ml, p

    الوصف: Background The enhanced thrombotic milieu in diabetes contributes to increased risk of vascular events. Aspirin, a key antiplatelet agent, has inconsistent effects on outcomes in diabetes and the best dosing regimen remains unclear. This work investigated effects of aspirin dose and interaction with glycaemia on both the cellular and protein components of thrombosis. Methods A total of 48 participants with type 1 diabetes and 48 healthy controls were randomised to receive aspirin 75 or 300 mg once-daily (OD) in an open-label crossover study. Light transmittance aggregometry and fibrin clot studies were performed before and at the end of each treatment period. Results Aspirin demonstrated reduced inhibition of collagen-induced platelet aggregation (PA) in participants with diabetes compared with controls, although the higher dose showed better efficacy. Higher aspirin dose facilitated clot lysis in controls but not individuals with diabetes. Collagen-induced PA correlated with glycaemic control, those in the top HbA1c tertile having a lesser inhibitory effect of aspirin. Threshold analysis suggested HbA1c levels of > 65 mmol/mol and > 70 mmol/mol were associated with poor aspirin response to 75 and 300 mg daily doses, respectively. Higher HbA1c was also associated with longer fibrin clot lysis time. Conclusions Patients with diabetes respond differently to the antiplatelet and profibrinolytic effects of aspirin compared with controls. In particular, those with elevated HbA1c have reduced inhibition of PA with aspirin. Our findings indicate that reducing glucose levels improves the anti-thrombotic action of aspirin in diabetes, which may have future clinical implications.
