The developments in apheresis technologies and techniques and their clinical applications worldwide are technologically, sociologically, and economically motivated. As in the past apheresis surveys, the statistics have highlighted both the differences by geographic region in clinical practice and in the type of technologies utilized. While a national view of apheresis is very important, an international view may be more representative overall of this therapeutic modality than national results that are highly dependent on the local economics and the available technologies. These regional differences have provided a basis for scientific and clinical assessment of these apheresis technologies and their clinical outcomes, and have impacted the marketing and business developments of new technologies worldwide. The results of the International Apheresis Registry for 2007 report data from 20 centers on five continents. The survey collected data exclusively via a secure internet website on 1735 patients for a total of 6787 treatments. As with our prior registry for 2005, information on stem cell infusions was gathered. Information collected included patients demographics, medical history, treatment diagnoses, treatment specifics (type, methodology, access type, anticoagulants, drugs, and equipment usage), side effects, clinical response, and payment provider. As in prior International Apheresis Registries for 1983, 2000, 2002, and 2005, the survey results highlight the regional differences in apheresis usage and treatment methodologies indicating that an international overview of apheresis may be more representative of the impact of this therapeutic modality.
