ABSTRACT

We present the case of a 17-year-old man, who died after 2,4-dinitrophenol (DNP) and clenbuterol consumption, which he likely took for physical enhancement. Forensic post-mortem examination revealed a yellowish skin colour and nonspecific signs of asphyxia. Analytical confirmation of the intoxication was obtained in blood and urine, with high levels of DNP and clenbuterol. Both of these substances are used by bodybuilders as DNP enhance lipolysis and clenbuterol has anabolic properties, but their toxicity is underestimated. DNP uncouples oxidative phosphorylation, leading to thermogenesis and even relatively small doses can cause fatal hyperthermia. Clenbuterol is a ß2 agonist that causes electrolyte disturbances (hypokalemia and hyperglycemia mostly) and death have been described through coronary vasospasm. Given the circumstances in which the body was found and toxicological results, we believe the cause of death to be fatal hyperthermia from DNP intake. These substances are illegal in many countries, but easily bought online. Through this availability, the last decades have seen an increase of fatal intoxications. Websites selling them are regularly closed by French public authorities and Interpol, but unfortunately it seems insufficient.

ABSTRACT

The French National Laboratory of the International Olympic Committee (IOC) has detected norandrosterone (NA) and noretiocholanolone (NE) in urine samples from several sportsmen. These two substances are known to be urinary metabolites after nandrolone intake. In such cases, the NA level is always higher than the Ne level. However, in the urine samples of sportsmen tested positive, the NE concentrations were systematically higher than the NA levels. We therefore searched for other steroid precursors (commercially available capsules or tablets of dehydroepiandrosterone, 4-androstenediol, 5-androstenediol, 4-androstenedione, 19-norandrostenediol and 19-norandrostenedione, also illegally used in France) which could lead to an excretion of NA and NE and to an inverted ratio of these metabolites.

ABSTRACT

In France during a famous bicycle race, the newspapers documented the degree in which doping seemed to be supervised in some teams by managers and doctors. Use of anabolic steroids and other substances was officially banned in the mid-seventies by sports authorities. This policy has been enforced through urine testing before competition. It is well known, however, that a latency period is all that is necessary to defeat these tests. Nevertheless, hair analysis could be a promising tool when testing for periods that are not accessible to urinalysis any more. We have developed different sensitive methods for testing hair for amphetamines, anabolic steroids and their esters and corticosteroids. For amphetamines, 50 mg of hair were digested with 1 M NaOH, extracted with ethyl acetate, derivatized with TFA and analyzed by gas chromatography positive chemical-ionization mass spectrometry. For corticosteroids, 50 mg of powdered hair were treated with methanol in an ultrasonic bath and subsequently purified using a C18 solid phase extraction column. Analysis was realized by high performance liquid chromatography coupled to electrospray-ionization tandem mass spectrometry. For anabolic steroids and their esters, 100 mg of powdered hair were treated with methanol in an ultrasonic bath for extraction of esters, then alkaline digested with 1 M NaOH for an optimum recovery of other drugs. The two liquid preparations were subsequently extracted with ethyl acetate, pooled, then finally highly purified using a twin solid phase extraction on aminopropyl and silica cartridges. Residue was derivatized with MSTFA prior to injection. Analysis was conducted by gas chromatography coupled to a triple quadrupole mass spectrometer. Thirty cyclists were sampled and tested both in hair and in urine. Amphetamine was detected 10 times in hair (out of 19 analyses) compared to 6 times in urine (out of 30 analyses). Corticosteroids were detected 5 times in hair (methylprednisolone 1 case, triamcinolone acetonide 3 cases and hydrocortisone acetate 1 case) in hair (out of 12 analyses) compared to 12 times (triamcinolone acetonide 10 cases and betamethasone 2 cases) in urine (out of 30 analyses). Anabolic steroids were detected twice (nandrolone 1 case, and testosterone undecanoate 1 case) in hair (out of 25 analyses) compared to none in urine (out of 30 analyses).

ABSTRACT

We have developed a powerful and simple sensitive method for testing hair for anabolic steroids and their esters. A 100-mg amount of powdered hair was treated with methanol in an ultrasonic bath for extraction of esters, then alkaline digested with 1 M NaOH for an optimum recovery of other drugs. The two liquid preparations were subsequently extracted with ethyl acetate, pooled, then finally highly purified using a twin solid-phase extraction on amino and silica cartridges. The residue was derivatized with N-methyl-N(trimethylsilyl)-trifluoracetamide (MSTFA) prior to injection. Analysis was conducted by gas chromatography coupled to a triple quadrupole mass spectrometer. The generally chosen parent ion was the molecular ion while two daughter ions were selected for each compound with collision energies ranging from -16 to -21 eV. Internal standards were nandrolone d3 for non-esterified drugs and testosterone phenyl propionate for esters. The limits of detection calculated from an analysis of the blanks (n=30) were 0.08 pg/mg for nandrolone, 6.20 pg/mg for boldenone, 0.07 pg/mg for methyl testosterone, 0.15 pg/mg for ethinyl estradiol, 2.10 pg/mg for metandienone, 0.86 pg/mg for testosterone propionate, 0.95 pg/mg for testosterone cypionate, 1.90 pg/mg for nandrolone decanoate, 3.10 pg/mg for testosterone decanoate and 4.80 pg/mg for testosterone undecanoate. Application to doping control has been demonstrated. In a series of 18 sportsmen, two tested positive for anabolic steroids in hair whereas urinalysis was negative for both of them. The first positive case was nandrolone and the second case concerned the identification of testosterone undecanoate. Measured in 10 white males aged between 22 and 31 years, the testosterone concentration was in the range 1.7-9.2 pg/mg (mean=5.0 pg/mg). The method was also applied in meat quality control. Of the 187 analyses realized based upon hair and urine sampling in slaughter houses, 23 were positive for anabolic steroids in hair: one case for boldenone, one case for metandienone, two cases for testosterone propionate, three cases for nandrolone, five cases for testosterone decanoate and 11 cases for methyl testosterone. In the meantime, urinalysis was always negative for these drugs or their metabolites.

ABSTRACT

A procedure is presented for the identification of nordiazepam and its metabolite, oxazepam, in human hair. The method involves decontamination of hair with dichloromethane, incubation in phosphate buffer (pH 7.6) in the presence of deuterated internal standards, liquid-liquid extraction, derivatization with N,O-bis(trimethylsilyl)trifluoroacetamide plus 1% trimethylchlorosilane and gas chromatography-mass spectrometry using negative-ion chemical ionization with methane. Among thirty samples obtained from polydrug abusers, thirteen tested positive for nordiazepam, in the range of 0.25-18.87 ng/mg. Five samples were also positive for oxazepam, in the range 0.11-0.50 ng/mg.

ABSTRACT

Hair samples were obtained from 36 drug addicts deceased from fatal heroin overdose. Samples were decontaminated with dichloromethane and pulverized. 50 mg of powdered hair were incubated 2 h at 40 degrees C in a phosphate buffer pH 7.6 in presence of deuterated internal standards (Nordiazepam-d5 and Oxazepam-d5) and extracted by a mixture ether/chloroform (80:20, v/v) at pH 8.4. After evaporation of the solvent, the dry extract was derivatized by silylation (BSTFA + 1% TMCS) and analyzed by gas chromatography coupled to mass spectrometry, with a detector operating in negative chemical ionization mode. 13 samples tested positive for Nordiazepam with concentrations ranging from 0.25 to 18.87 ng/mg of hair (mean: 4.16 ng/mg) and 5 positives for its metabolite, Oxazepam, with concentrations ranging from 0.11 to 0.50 ng/mg of hair (mean : 0.28 ng/mg).
