title: Development of a UHPLC-MS/MS method for the determination of plasma histamine in various mammalian species.
abstract: Histamine is an important mediator of anaphylactic reactions. Although several methods have been developed to measure histamine levels, each has its limitations. In this study, we developed and validated a convenient bioanalytical method for the qualitative and quantitative determination of histamine in plasma samples from humans, beagle dogs, Sprague-Dawley rats, and imprinting control region mice. A simple plasma protein precipitation method using acetonitrile was selected, and hydrophilic interaction liquid chromatography coupled with mass spectrometry was used for sample separation and detection. Histamine was subjected to gradient elution with acetonitrile, ammonium acetate buffer, and formic acid. A mass spectrometer equipped with an electrospray ionization source was operated in the positive-ion multiple reaction monitoring mode for the detection of histamine and the internal standard. The [M+H](+) transitions were m/z 112→95 for histamine and m/z 116→99 for d4-histamine, which was used as the internal standard. The lower limit of quantification was 0.2μg/L and the calibration range was 0.2-500μg/L. The overall recovery ranged from 93.6% to 102.8%. The intra- and inter-run precision and accuracy were <15% for plasma samples from all four species. The method was validated by measuring the plasma histamine concentrations in five healthy human volunteers. In conclusion, we have developed and validated a novel bioanalytical method for the quantification of histamine levels in plasma samples from various mammalian species.
