Teicoplanin, a glycopeptide antibiotic against Gram-positive bacteria, is used during continuous venovenous hemodiafiltration (CVVHDF), though adsorption onto a hemofilter has been observed in an in-vitro study. We report a case of extensive augmentation of teicoplanin clearance by a polymethyl methacrylate (PMMA) hemofilter. A 74-year-old man (body weight 53 kg) was performed CVVHDF with the PMMA hemofilter. The effluent flow rate maintained at 600-650 mL/h. The measured teicoplanin clearance was 31.0 mL/min, and the clearance was reduced to 11.1 mL/min over the next 6.5 hours. In conclusion, we should closely monitor teicoplanin dosing during CVVHDF using a PMMA membrane hemofilter.
