Removal of immunoglobulins by a protein A versus an antihuman immunoglobulin G-based system: evaluation of 602 sessions of extracorporeal immunoadsorption

Elimination of IgG can be achieved by extracorporeal immunoadsorption (IA) based on specific binding to either staphylococcal protein A (Excorim) or sheep polyclonal antibodies directed against human IgG (Therasorb). In 602 analyzed sessions of IA, elimination of IgG was 60% through 80% depending on the treated plasma volume, with no significant difference between the mentioned systems. However, the decrease of IgM and IgA was approximately 50% in the anti-IgG compared to 20-40% in the protein A system. Plasma albumin concentration decreased by 20% in the anti-IgG system compared to 15% in the protein A system, and hemoglobin values increased by 2% in the anti-IgG system and decreased by 6% in the protein A system. In conclusion, a clinical relevance for these findings cannot be ruled out, and the individual choice might depend on the clinical situation and laboratory findings.

Effect of single and multiple administration of an O 6-benzylguanine/temozolomide combination: an evaluation in a human melanoma xenograft model

The purpose of the present study was to examine the effect of O ⁶-benzylguanine (O ⁶-BG) on the antitumour activity and toxicity of 8-carbamoyl-3-methylimidazo [5, 1-d ] -1,2,3,5-tetrazine-4(3H)-one (temo-zolomide) in a human malignant melanoma xenograft model following single and multiple administration of the combination. O ⁶-BG irreversibly inactivates the DNA-repair protein O ⁶-alkylguanine-DNA alkyltransferase (AGT), which confers resistance to temozolomide. Preadministration of O ⁶-BG (35 mg/kg, i.p.) 1 h prior to temozolomide (i.p.) was examined using single and daily × 5 dosing regimens in athymic mice bearing subcutaneous A375P xenografts. The AGT activity of A375P tumors was 95 ± 8 fmol/mg protein (mean ± SE, n = 4). O ⁶-BG alone completely suppressed xenograft AGT activity within 1 h of administration but had no effect upon tumor growth. O ⁶-BG did not significantly increase the tumor growth delay induced by a single 200-mg/kg dose of temozolomide (P>0.05, two-tailed Mann-Whitney test) but did increase the associated mean body weight loss (P<0.025). In contrast, when the same dose of temozolomide was divided into five equal fractions (40 mg/kg) and given with O ⁶-BG on 5 consecutive days, a comparable increase in toxicity was accompanied by a very significant increase in tumor growth delay (P<0.0025), equivalent to that produced by a 3-fold greater dose of temozolomide alone. O ⁶-BG with temozolomide also produced a greater antitumour effect than an equitoxic dose of temozolomide alone on this schedule (P<0.005). These data indicate that the enhancement of temozolomide antitumour activity by O ⁶-BG preadministration is dependent upon the schedule of drug administration, with multiple dosing of O ⁶-BG + temozolomide producing the greatest effect. The results also suggest that prolonged administration of the combination can lead to an increase in the therapeutic index of temozolomide.

加速超分割放射治疗鼻咽癌前瞻性研究的近期结果

目的：为了探讨加速超分割放射治疗鼻咽癌的临床效果和早、晚期放射反应。方法：１９９５年１月～１９９６年７月首次住院放疗的鼻咽癌患者２６６例。随机分为加速超分割（ＡＨＦ）和常规分次（ＣＦ）对照两组，均经ＣＴ或ＭＲＩ检查及Ｐｌａｔｏ治疗计划系统设计布野。对鼻咽部ＡＨＦ组方案为ＤＴ７９．２Ｇｙ／７２次／２４个治疗日，全程３２天，１．１Ｇｙ／次，每天３次，各次之间间隔＞６ｈ；对照组的方案是ＤＴ７０Ｇｙ／３５次７周，２Ｇｙ／次，每周５次。颈结（＋）给予治疗量，ＡＨＦ组７９．２Ｇｙ，对照组７０Ｇｙ；颈结（－）给予预防量，ＡＨＦ组５０Ｇｙ，对照组４５Ｇｙ。结果：ＡＨＦ组的疗终病灶全消和１年生存率优于对照组，差异有统计学意义。而急性放射反应，则明显重于对照组，皮肤粘膜Ⅲ度放射反应增多。差异非常显著。实验组有１０．７％患者需要短期中断疗程和支持治疗。结论：加速超分割放疗鼻咽癌的近期效果较好，疗终病灶全消率和１年生存率均优于常规分次组（Ｐ＜０．０１和０．０５）。虽然急性放射反应较重，但大多数患者可以耐受。
