National survey of apheresis activity in Italy (2000)

Data collection on apheresis in Italy throughout 2000, including techniques, machines, clinical indications and adverse effects, has been performed by means of a standardized questionnaire. These data provided from 102 Apheresis Units from 19 Italian regions, albeit rough, are sufficiently informative. In 2000 a total number of 164,943 apheresis procedures has been carried out, with a clear-cut prevalence of productive apheresis (90.8%), that has been performed by all Apheresis Units. Lombardy, Venetia and Liguria have been the most active regions for therapeutic apheresis (54.0% of the total activity). Adverse events, predominantly mild ones (i.e., paresthesia due to citrate-induced hypocalcemia) have occurred in 0.59% of productive and in 6.75% of therapeutic apheresis sessions, particularly in the course of peripheral blood stem cell collection (13.0%).
