Abstract

OBJECTIVES

To determine the concentrations of nicotine and nicotine metabolites in RBC units as a means to estimate the point prevalence of exposure within the healthy donor pool.

METHODS

Segments from 105 RBC units were tested for the presence of nicotine, cotinine, or trans-3'-hydroxycotinine by liquid chromatography-tandem mass spectrometry.

RESULTS

Of the 20 (19%) units that contained detectable concentrations of nicotine, cotinine, or trans-3'-hydroxycotinine, 19 (18.1%) contained concentrations consistent with the use of a nicotine-containing product within 48 hours of specimen collection. One RBC unit contained nicotine concentrations consistent with passive exposure.

CONCLUSIONS

Chemicals from nicotine-containing products are detectable within the US RBC supply. Further investigation is needed to determine the risks of transfusion-associated exposure to nicotine and other tobacco-associated chemicals among vulnerable patient populations such as neonates.

摘要

目的

通过检测 RBC 单位中尼古丁及其代谢物的浓度,来估计健康供者群体中暴露的时点流行率。

方法

采用液相色谱-串联质谱法检测 105 个 RBC 单位中尼古丁、可替宁或反式-3'-羟基可替宁的存在情况。

结果

在 20 个(19%)含有可检测浓度尼古丁、可替宁或反式-3'-羟基可替宁的单位中,19 个(18.1%)的浓度与标本采集后 48 小时内使用含尼古丁产品一致。一个 RBC 单位中含有尼古丁的浓度与被动暴露一致。

结论

在美国的 RBC 供应中可检测到含尼古丁产品的化学物质。需要进一步研究,以确定在新生儿等脆弱患者群体中,与输血相关的尼古丁和其他与烟草相关的化学物质暴露的风险。
