Key clinical point : Alemtuzumab infusion in patients with multiple sclerosis (MS) is associated with the elevation of D-dimer level and the prolongation of prothrombin time (PT).
Major finding : Alemtuzumab infusion resulted in a significant elevation in D-dimer levels within the patient group (before vs after infusion, P = .00001) and also compared with control individuals ( P = .00001). PT was also prolonged in patients receiving alemtuzumab post-infusion compared with the pre-infusion values ( P = .00001).
Study details : In this study, coagulation parameters were analyzed in 13 patients with MS treated with alemtuzumab and 13 control individuals.
