Probing the hair detectability of prohibited substances in sports: an in vivo-in silico-clinical approach and analytical implications compared with plasma, urine, and faeces.

[PMID: 38224356 PMCID: PMC10861659 DOI: 10.1007/s00204-023-03667-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Accepted: 12/14/2023] [Indexed: 01/16/2024]
Abstract
Hair analysis is a crucial method in forensic toxicology with potential applications in revealing doping histories in sports. Despite its widespread use, knowledge about detectable substances in hair is limited. This study systematically assessed the detectability of prohibited substances in sports using a multifaceted approach. Initially, an animal model received a subset of 17 model drugs to compare dose dependencies and detection windows across different matrices. Subsequently, hair incorporation data from the animal experiment were extrapolated to all substances on the World Anti-Doping Agency's List through in-silico prediction. The detectability of substances in hair was further validated in a proof-of-concept human study involving the consumption of diuretics and masking agents. Semi-quantitative analysis of substances in specimens was performed using ultra-performance liquid chromatography-tandem mass spectrometry. Results showed plasma had optimal dose dependencies with limited detection windows, while urine, faeces, and hair exhibited a reasonable relationship with the administered dose. Notably, hair displayed the highest detection probability (14 out of 17) for compounds, including anabolic agents, hormones, and diuretics, with beta-2 agonists undetected. Diuretics such as furosemide, canrenone, and hydrochlorothiazide showed the highest hair incorporation. Authentic human hair confirmed diuretic detectability, and their use duration was determined via segmental analysis. Noteworthy is the first-time reporting of canrenone in human hair. Anabolic agents were expected in hair, whereas undetectable compounds, such as peptide hormones and beta-2 agonists, were likely due to large molecular mass or high polarity. This study enhances understanding of hair analysis in doping investigations, providing insights into substance detectability.

J Chromatogr Sci 2023; 61:605-611.

Abstract
A simple, rapid, sensitive and specific gas chromatography-tandem mass spectrometry (GC-MS/MS) method was developed for quantitation of salbutamol in human urine using salbutamol-d3 as the internal standard. The processing of urines samples includes deconjugation with enzymatic hydrolysis, solid phase extraction procedure utilizing XAD2 column and liquid-liquid extraction accompanied by the derivatization by means of MSTFA/IODO-TMS/DTE mixture. The GC column was a HP Ultra-1 (17 m × 0.22 mm × 0.11 μm) used to separate the peak of interest. The data for GC-MS/MS were acquired and processed utilizing GC Labs Solution and Insight GCMS Software. The detection of spectra was performed on TQ 8050. This method included a chromatographic run of 13.67 min and the linearity was found over the concentration range of 250-2000 ng/mL with a regression coefficient (r2) of 0.99. The coefficient of variation for intra and interday assay precision was between 1.85 and 2.85% and the accuracy was between 95.50 and 107.04% for low quality control (QC), medium QC and high QC. The recovery was adequate to reliable detect the analyte at or below the level recommended by the World Anti-Doping Agency i.e., threshold 1000 ng/mL. The limit of detection and limit of quantification were found to be 10 and 100 ng/mL, respectively. The expanded measurement uncertainty (Uexp%) was found to be 8.28%.

Abstract
Introduction:
Ultra-Performance Liquid Chromatographic (UPLC) method enables analyst
to establish an analysis at higher pressure than High Performance Liquid Chromatographic (HPLC)
method towards liquid chromatographic methods. UPLC method provides the opportunity to study a
higher pressure compared to HPLC, and therefore smaller column in terms of particle size and internal
diameter are generally used in drug analysis. The UPLC method has attracted gradually due to its advantages
such as short analysis time, the small amount of waste reagents and the significant savings in
the cost of their destruction process. In this review, the recent selected studies related to the UPLC
method and its method validation are summarized. The drug analyses and the results of the studies
which were investigated by UPLC method, with certain parameters from literature are presented.
Background:
Quantitative determination of drug active substances by High-Performance Liquid
Chromatography (HPLC) from Liquid Chromatography (LC) methods has been carried out since the
1970's with the use of standard analytical LC methods. In today's conditions, rapid and very fast even
ultra-fast, flow rates are achieved compared to conventional HPLC due to shortening analysis times,
increasing method efficiency and resolution, reducing sample volume (and hence injection volume),
reducing waste mobile phase. Using smaller particles, the speed and peak capacity are expanding to
new limit and this technology is named as Ultra Performance Liquid Chromatography. In recent years,
as a general trend in liquid chromatography, ultra-performance liquid chromatography has taken the
place of HPLC methods. The time of analysis was for several minutes, now with a total analysis time
of around 1-2 minutes. The benefits of transferring HPLC to UPLC are much better understood when
considering the thousands of analyzes performed for each active substance, in order to reduce the cost
of analytical laboratories where relevant analysis of drug active substances are performed without
lowering the cost of research and development activities.
Methods:
The German Chemist Friedrich Ferdinand Runge, proposed the use of reactive impregnated
filter paper for the identification of dyestuffs in 1855 and at that time the first chromatographic method
in which a liquid mobile phase was used, was reviewed. Christian Friedrich Chönbein, who reported
that the substances were dragged at different speeds in the filter paper due to capillary effect, was
followed by the Russian botanist Mikhail S. Tswet, who planted studies on color pigment in 1906.
Tswet observes the color separations of many plant pigments, such as chlorophyll and xanthophyll
when he passes the plant pigment extract isolated from plant through the powder CaCO3 that he filled
in the glass column. This method based on color separation gives the name of "chromatographie"
chromatography by using the words "chroma" meaning "Latin" and "graphein" meaning writing.
Results and Conclusion:
Because the UPLC method can be run smoothly at higher pressures than the
HPLC method, it offers the possibility of analyzing using much smaller column sizes and column diameters.
Moreover, UPLC method has advantages, such as short analysis time, the small amount of
waste reagents and the significant savings in the cost of their destruction process. The use of the
UPLC method especially analyses in biological samples such as human plasma, brain sample, rat
plasma, etc. increasingly time-consuming due to the fact that the analysis time is very short compared
to the HPLC, because of the small amount of waste analytes and the considerable savings in their cost.
