Evaluating coagulation disorders in the use of bevacizumab for metastatic colorectal cancer by thrombelastography.

The aim of this study was to evaluate coagulation disorders in patients with metastatic colorectal cancer treated with bevacizumab by using rotation thrombelastogram (ROTEM(®)) and correlate ROTEM(®) parameters with routine coagulation tests. A total of 18 colorectal cancer patients who received bevacizumab combined with chemotherapy were included. There was no statistically significant difference between results of platelet count, prothrombin time (PT) and activated partial thromboplastin time (APTT), fibrinogen, and D-Dimer obtained at baseline and on day 1 of chemotherapy cycles 4, 8, and 12.

Effects of immunosuppressive drugs on platelet aggregation and soluble P-selectin levels in renal transplant patients.

Background/aim: Post-transplant cardiovascular events are associated with increased morbidity and mortality after renal transplantation. Though renal transplantation eliminates cardiovascular disease risk factors by restoring renal function, it introduces new cardiovascular risks derived partly from immunosuppressive medications. In this study, to assess the effects of various immunosuppressive drugs on platelet function of renal transplant patients, we measured soluble P selectin levels (sP-selectin) and performed platelet aggregation studies in patients who have undergone renal transplantation.
