Postmortem redistribution (PMR) refers to the site- and time-related blood drug concentration variations after death. We compared central blood (cardiac and subclavian) with peripheral blood (femoral and popliteal) concentrations of diazepam, methadone, and morphine. To our knowledge, popliteal blood has never been compared with other sites. Intracardiac blood (ICB), subclavian blood (SB), femoral blood (FB), and popliteal blood (PB) were sampled in 30 cases. To assess PMR, mean concentrations and ratios were compared. Influence of postmortem interval on mean ratios was also assessed. Results show that popliteal mean concentrations were lower than those for other sites for all three drugs, even lower than femoral blood; mean ratios suggested that the popliteal site was less subject to PMR, and estimated postmortem interval did not influence ratios except for diazepam and methadone FB/PB. In conclusion, our study is the first to explore the popliteal site and suggests that popliteal blood is less prone to postmortem redistribution. [less ▲]

In the present study, we investigated the temporal within-person variability of the exposure biomarker for phthalates, parabens and benzophenone-3 (BP3) in 32 Belgian adults, each providing 11 urine spots during 4 months. We calculated the intraclass coefficient correlation (ICC), the sensitivity and the specificity to assess the temporal reproducibility and to investigate the predictive ability of the spot measurements for these classes of chemicals. Additionally, we explored the temporal variability of the estimation of the cumulative risk of exposure to phthalates (hazard index; HI). We observed fair ICC ranging from 0.55 to 0.68 for parabens, monoethyl phthalate (MEP), mono-iso-butyl phthalate (MiBP) and BP3, but lower ICC, from 0.20 to 0.49, for monobenzyl phthalate (MBzP), mono-n-butyl phthalate (MnBP), mono-2-ethylhexyl phthalate (MEHP), mono-2-ethyl-5-oxo-hexyl phthalate (5-oxo-MEHP) and mono-2-ethyl-5-hydroxy-hexyl phthalate (5-OH-MEHP). The ICC estimated for HI (0.49) reflected a moderate reproducibility. The measurements in spot samples were moderate to good predictor of the 4-month level of exposure for parabens, MEP, MnBP, MiBP, BP3 and HI (sensitivity ranging from 0.67 to 0.77), but lower predictor for MEHP, 5-oxo-MEHP, 5-OH-MEHP and MBzP (sensitivity ranging from 0.58 to 0.63). The sensitivity could be increased when several spot urinary levels were averaged to predict the long-term level of exposure. Globally, our results indicate that a single spot measurement seems to correctly represent the long-term exposure for parabens, BP3, MEP, MiBP and HI. Additional spot samples seemed to be needed for the proper exposure assessment of the other target compounds. [less ▲]

Systemic Sclerosis (SSc) is a chronic multisystemic connective tissue disease characterized by progressive fibrosis affecting skin and internal organs. Despite serious efforts to unveil the pathogenic mechanisms of SSc, they are still unclear. High levels of Reactive Oxygen Species (ROS) in affected patients have been shown, and ROS are suggested to play a role in fibrosis pathogenesis. In this study we evaluate ROS levels in non-fibrotic and fibrotic skin of patients with SSc and we compare them with those obtained from healthy controls. Patients and Methods We enrolled 9 SSc patients fulfilling the EULAR/ACR classification criteria and 7 healthy controls. Patients included were 4 men and 5 women with mean age of 46 ±10 yrs. Controls were matched by sex and age. All patients were affected by diffuse cutaneous form of SSc and the ANA pattern anti-Scl70. Mean disease duration was 7.5±5 yrs. Skin involvement was evaluated by modified Rodnan Skin Score (mRSS). Skin samples (4 mm punch biopsy) were taken from fibrotic skin and non-fibrotic skin of patients and from healthy controls as well. To detect ROS, specimens were analyzed immediately after sampling by electron paramagnetic resonance spectroscopy. Blood samples have been drawn from all patients and controls to assess oxidative stress biomarkers. Results ROS levels (expressed as median and range, unit of measurement was nmol/l/min/mg of dry weight) were 24.7 (10.9– 47.0) in fibrotic skin, 18.7 (7.3–34.0) in non-fibrotic skin and 7.7 (3.5–13.6) in healthy controls skin. ROS levels in Fibrotic and Non-fibrotic skin of SSc patients were significantly higher than in Healthy Controls (p=0.002 and p=0.009, respectively). ROS levels in fibrotic skin were raised in comparison to non-fibrotic skin, when samples related to each patient were compared (p=0.01). ROS levels in fibrotic skin were correlated with forced vital capacity (r= -0.75, p=0.02) and erythrocyte sedimentation rate (r=0.70, p=0.04). All other clinical and lab parameters showed no significant correlation. When compared to controls, blood from SSc patients showed lower ascorbate (vitamin C) levels (8 [3.8-9.8] vs. 10.5 [9-19.1] mg/L, p=0.004) and higher lipid peroxides (873.5 [342-1973] vs. 422 [105-576] μmol/L, p=0.004). Conclusion Our results indicate the presence of high oxidative stress both in non-fibrotic skin and fibrotic skin of SSc patients, but with higher tendency in the latter. Raised ROS levels in non-fibrotic skin of SSc patients might be a hint of early involvement in skin fibrogenesis. However, a longitudinal prospective study is necessary for such proof. [less ▲]

The toxicity of methylmercury (MeHg) in humans is well established and the main source of exposure is via the consumption of large marine fish and mammals. Of particular concern are the potential neurodevelopmental effects of early life exposure to low-​levels of MeHg. Therefore, it is important that pregnant women, children and women of childbearing age are, as far as possible, protected from MeHg exposure. Within the European project DEMOCOPHES, we have analyzed mercury (Hg) in hair in 1799 mother-​child pairs from 17 European countries using a strictly harmonized protocol for mercury anal. Parallel, harmonized questionnaires on dietary habits provided information on consumption patterns of fish and marine products. After hierarchical cluster anal. of consumption habits of the mother-​child pairs, the DEMOCOPHES cohort can be classified into two branches of approx. similar size: one with high fish consumption (H) and another with low consumption (L)​. All countries have representatives in both branches, but Belgium, Denmark, Spain, Portugal and Sweden have twice as many or more mother-​child pairs in H than in L. For Switzerland, Czech Republic, Hungary, Poland, Romania, Slovenia and Slovakia the situation is the opposite, with more representatives in L than H. There is a strong correlation (r=0.72) in hair mercury concn. between the mother and child in the same family, which indicates that they have a similar exposure situation. The clustering of mother-​child pairs on basis of their fish consumption revealed some interesting patterns. One is that for the same sea fish consumption, other food items of marine origin, like seafood products or shellfish contribute significantly to the mercury levels in hair. We conclude that addnl. studies are needed to assess and quantify exposure to mercury from seafood products, in particular. The cluster anal. also showed that 95​% of mothers who consume once per wk fish only, and no other marine products, have mercury levels 0.55 μg​/g. Thus, the 95th percentile of the distribution in this group is only around half the US-​EPA recommended threshold of 1 μg​/g mercury in hair. Consumption of freshwater fish played a minor role in contributing to mercury exposure in the studied cohort. The DEMOCOPHES data shows that there are significant differences in MeHg exposure across the EU and that exposure is highly correlated with consumption of fish and marine products. Fish and marine products are key components of a healthy human diet and are important both traditionally and culturally in many parts of Europe. Therefore, the communication of the potential risks of mercury exposure needs to be carefully balanced to take into account traditional and cultural values as well as the potential health benefits from fish consumption. European harmonized human biomonitoring programs provide an addnl. dimension to national HMB programs and can assist national authorities to tailor mitigation and adaptation strategies (dietary advice, risk communication, etc.) to their country's specific requirements.

OBJECTIVES: In Rwanda, no therapeutic monitoring of psychotropic drugs is done. This results in difficult treatment optimisation and exposition to a high risk of toxicity and drug ineffectiveness for patients under treatment. This study aimed to determine blood concentration levels of psychotropic drugs in Rwandan patients and identify problems associated with the lack of therapeutic drug monitoring (TDM) of these drugs. METHODS: The analysis was performed on 1 ml of serum sample using prazepam as internal standard. Regarding the step of sample preparation, we used a liquid-liquid extraction with a mixture of organic solvents: diethyl ether/dichloromethane/hexane/n-amyl alcohol (50/30/20/0.5:V/V). A Waters Alliance 2695 was used for analysis. The chromatography was run on a Symmetry C8 column and as mobile phase acetonitrile and phosphate buffer (pH 3.8) were used. RESULTS: Concerning the results, serum samples from 128 patients were analysed. Twenty-one different psychotropic drugs belonging to various pharmacological classes were detected and quantified. Analytical results were put into three categories based upon therapeutic reference ranges (TRR) of various drugs: subtherapeutic, therapeutic and supratherapeutic. For a total of 237 analyses, results within TRR represented 46% while 47 and 8% of results were, respectively, below and above TRR. CONCLUSION: It was therefore concluded that patients under psychotropic treatment in Rwanda are exposed to both the risk of drug ineffectiveness and the risk of toxicity (54%) with only 46% of results within the TRR. Consequently, TDM is needed to optimise psychotropic treatment in Rwandan patients. [less ▲]

As a cornerstone of quality management in the laboratory, External Quality Assessment (EQA) schemes are used to assess laboratory and analytical method performance. The characteristic function is used to describe the relation between the target concentration and the EQA standard deviation, which is an essential part of the evaluation process. The characteristic function is also used to compare the variability of different analytical methods. We fitted the characteristic function to data from the Belgian External Quality Assessment program for serum ethanol. Data included results from headspace gas chromatography and the enzymatic methods of Abbott, Roche, Siemens, and Ortho-Clinical Diagnostics. We estimated the characteristic function with weighted nonlinear regression. By introducing dummy variables, we rewrote the original formula of the characteristic function to assess statistical inference for comparing the variability of the different analytical methods. The characteristic function fitted the data precisely. Comparison between methods showed that there was little difference between the estimated variability for low concentrations, and that the increase in SD with increasing target concentration was slower for Abbott and Roche than for the other methods. The characteristic function can successfully be introduced in clinical schemes, although its applicability to fit the data should always be assessed. Because of its easy parameterization, it can be used to assess differences in performance between analytical methods and to assess laboratory performance. The characteristic function also offers an alternative framework for coefficients of variation to describe variability of analytical methods. [less ▲]

Objectif Les patients porteurs de prothèse de hanche à couple métal-métal (PHM) présentent un taux de cobalt circulant supérieur à celui de la population générale. Chez ces patients, le dosage du cobalt permet d’apprécier le risque toxique éventuel de l’implant et peut servir d’indicateur de révision ou de remplacement de cette prothèse. A cette fin, une méthode de dosage a été validée et appliquée à des patients porteurs de PHM. Méthode Le dosage du cobalt est réalisé sur 500 μL de sang total, après dilution dix fois dans une solution aqueuse acide et après ajout de 100 μL d’une solution de standard interne titrée à 500 μg/L de germanium. L’échantillon est ensuite analysé par un spectromètre de masse avec source d’ionisation par plasma induit haute fréquence (ICP-MS). La méthode décrite a été validée par l’approche de l’erreur totale au moyen du logiciel e•noval (Arlenda®). Résultats La méthode de dosage a été validée avec succès. Elle est linéaire de 0,5 à 50 μg/L. L’inexactitude et l’imprécision intra- et inter-essais sont inférieures à 5 % et 8 %, respectivement. L’incertitude de mesure est inférieure à 17 %. La concentration sanguine moyenne de cobalt estimée sur une période de 1 an à partir de 107 prélèvements de patients porteurs de PHM est de 2,61 μg/L (nombre de patients : 98 ; âge moyen : 60 ans ; ratio hommes/femmes : 38/60). Ce résultat est inférieur au seuil recommandé dans ces populations, fixé à 7 μg/L de cobalt sanguin. Conclusion La méthode analytique présentée permet de doser le cobalt sanguin, notamment chez les patients porteurs de PHM. Ce dosage est recommandé pour le suivi de ces patients, en association avec un examen clinique et radiologique. [less ▲]

Background/Aims: Heroin-assisted treatment (HAT) can improve the condition of heroin addicts still using street heroin after a methadone treatment. In Belgium, a new trial compared the efficacy of a HAT to existing methadone maintenance treatment. Methods: In this randomised controlled trial, HAT was limited to 12 months. Participants were assessed every 3 months. They were responders if they showed improvement on the level of street heroin use, health or criminal involvement. Results: 74 participants were randomised in the trial. The experimental group (n=36) counted 30% of responders more than the control group (n=38) at each assessment point (p<0.05), except at 12 months where the difference (11%) was no longer significant (p=0.35). Still, after 12 months, participants in the experimental group reported significantly greater improvements (p<0.05) than the control group on the level of street heroin use and on the level of physical and mental health. Both groups reported significantly less criminal facts after 12 months (p<0.001), but with no significant difference between the groups. Conclusions: This trial confirms the short-term efficacy of HAT for severe heroin addicts, who already failed methadone treatment. [less ▲]

To develop a model for estimating the time delay between last heroin consumption and blood sampling in chronic drug users. Eleven patients, all heroin inhalers undergoing detoxification, were included in the study. Several plasma samples were collected during the detoxification procedure and analyzed for the heroin metabolites 6-acetylmorphine (6AM), morphine (MOR), morphine-6-glucuronide (M6G) and morphine-3-glucuronide (M3G), according to a UHPLC/MSMS method. The general linear mixed model was applied to time-related concentrations and a pragmatic four-step delay estimation approach was proposed based on the simultaneous presence of metabolites in plasma. Validation of the model was carried out using the jackknife technique on the 11 patients, and on a group of 7 test patients. Quadratic equations were derived for all metabolites except 6AM. The interval delay estimation was 2–4 days when only M3G present in plasma, 1–2 days when M6G and M3G were both present, 0–1 day when MOR, M6G and M3G were present and <2 h for all metabolites present. The ‘jackknife’ correlation between declared and actual estimated delays was 0.90. The overall precision of the delay estimates was 8–9 h. The delay between last heroin consumption and blood sampling in chronic drug users can be satisfactorily predicted from plasma heroin metabolites. [less ▲]

Objectives: The objective of the present study was to describe the results of the blood alcohol determinations made on drivers from the Liege area between July 2007 and December 2012. Methods: The results were interpreted according to the sex, to the age, to the circumstances and temporal variation of the blood test. Statistical analysis was performed using R® software. Results: During this 5-years period, 2725 determinations were done, mainly in the context of road crashes. The mean blood alcohol concentration (BAC) was 1.69 g/L, and 2132 drivers were above the legal threshold. A large majority of offenders (77%) were men, but the mean BAC did not differ significantly between men (1.69 g/L) and women (1.67 g/L). A statistically significant correlation between age and mean BAC can be observed, if we only consider the positive cases. Concerning the temporal variation of the results, lowest mean BACs are observed during the daytime while highest mean BACs are measured during the night. In both cases, no statistically significant difference can be observed if we compare the week and the weekend. Finally, no statistically significant difference in BAC was observed over years.
