Treatment of TTP is therapeutic plasma exchange (TPE) with replacement with fresh frozen plasma (FFP). Cryoprecipitate\u2010poor plasma (CPP) is a plasma product with lower concentrations of large VWF multimers, and similar amounts of ADAMTS13. CPP is regarded as at least as efficacious as FFP in TTP but evidence of additional benefits has not been demonstrated. Furthermore, there are limited data on the frequency of adverse events associated with CPP. Material and methods: In our center, the choice between CPP and FFP is performed before the 1st TPE session at the physicians' discretion. Here, we retrospectively evaluated the efficacy and safety of CPP based on the number of sessions, volume of plasma exposure, frequency of exacerbations\/relapses, and adverse events. Results: Fourteen patients with newly diagnosed TTP were included in this analysis. The proportion of CPP:FFP use was 5:9. There were no significant differences in age, gender, initial hemoglobin, platelet count, LDH, or etiology of TTP between groups. We observed a trend toward a higher number of TPE sessions and higher plasma exposure in CPP, compared to FFP\u2010treated patients. Acute exacerbations were more frequent among patients treated with CPP (OR 26.6; 95%CI 1.01\u2013703.51; <jats:italic>P<\/jats:italic>\u2009=\u20090.03). Mild allergic reactions were the most common treatment\u2010related adverse event in both groups. Discussion: Our data suggest that CPP should not be used as 1st line treatment for newly diagnosed TTP patients. J. Clin.
