Guillain-Barré syndrome (GBS) is an acute immune-mediated demyelinating polyradiculoneuropathy that could lead to disabilities if not properly treated. There are only limited data on the prognostic factors and complications when using double-filtration plasmapheresis in these patients. We reviewed the medical records of 60 GBS patients who underwent double-filtration plasmapheresis as the first-line therapy at a tertiary care teaching hospital. ⋯ In conclusion, we describe our experiences of using DFPP in the treatment of GBS. The pretreatment severity score was the most significant predictor of treatment outcome, suggesting that early referral and timely treatment are important. Potential complications such as catheter-related infection and deep vein thrombosis should be monitored carefully.

Hydroxyethyl starch (HES) is used to separate hematopoietic progenitor cells after bone marrow (BM) collection from red blood cells. The aims were to study alternatives for HAES-steril (200 kDa; not available anymore) and to optimize the sedimentation process. Using WBC-enriched product (10 × 10(9) WBC/L), instead of BM, sedimentation at 10% hematocrit using final 0.6 or 0.39% Voluven (130 kDa) or without HES appeared to be good alternatives for 0.6% HAES-steril. ⋯ Optimal sedimentation was reached using 110-140 mL volume. Centrifugation appeared not suitable for sedimentation. Additional testing with BM might be necessary to confirm these results.
