Therapeutic apheresis in Taiwan.
From July 1, 1999, to June 30, 2000, the Formosan Blood Purification Society conducted a survey on the current status of therapeutic apheresis (TA) treatments in Taiwan. There were 13 centers with a total of 437 patients, 498 courses, and 2,086 procedures. The most common indication was for neurological disorders (58.4%), which included mainly myasthenia gravis (34.9%) and Guillain-Barré syndrome (18.2%). The other indications were hematological disorders (19.3%), hepatic-pancreatic disorders (12.3%), and rheumatic disorders (7.1%). Seventy-one percent of TA treatments were reported to be effective. Plasma exchange (PE) performed by either centrifugation or the filtration method constituted 55.4% of TA treatments, the double-filtration (DF) method constituted 39.3% of treatments, and cytapheresis constituted 5.3% of treatments. The most common machines used for TA were the Plasauto iQ, the KM 8800, the Hemonetics series, and the Fenwal CS-3000. The overall frequency of complications was 42.2% per course and 12.9% per procedure. Among them, fever, urticaria, and hypotension were the major complications. As compared with the trends of TA treatment in the world, PE still represents the major TA treatment in Taiwan, which should be replaced by DF or more selective adsorptive methods to reduce the PE-related adverse effects.
