Atypical vancomycin pharmacokinetics were observed in an immunoglobulin A myeloma patient. Drug concentrations in serum were extremely elevated, the elimination half-life was prolonged despite normal renal function, and the vancomycin therapy was ineffective. Extensive binding of vancomycin, presumably by high concentrations of an aberrant immunoglobulin A protein, may have accounted for these observations.
在一名免疫球蛋白A骨髓瘤患者中观察到非典型的万古霉素药代动力学。血清中的药物浓度极度升高,尽管肾功能正常,但消除半衰期延长,且万古霉素治疗无效。万古霉素的广泛结合,推测是由于高浓度的异常免疫球蛋白A蛋白,可能是导致这些观察结果的原因。
