Effects of Extracorporeal Treatment in Patients With Acute Poisoning

This study aims to estimate the effect of extracorporeal treatments (ECTRs) on 28-day survival in patients with acute poisoning. The treatment strategy was receipt of ECTR (hemoperfusion, hemodialysis, continuous kidney replacement therapy, and/or or plasma exchange) versus a non-ECTR strategy.

Prediction of Detoxification Effect of Fat Emulsion Based on Drug Diffusion Law

The goal of this observational study is to establish a predictive model for the clinical use value of fat emulsion as an antidote based on the physical information of fat emulsion on drug diffusion process. The main question it aims to answer is: Observing the effect of fat emulsion on the pharmacokinetic changes of overdose drugs; Observe and evaluate the therapeutic effect of long-chain fat emulsion as an antidote; Participants will have their whole blood samples collected for toxicology testing.

Effectiveness of Environmental Measures to Eliminate the Risks of Lead Exposure in Infant Lead Poisoning

Infant lead poisoning is the clinical expression of lead poisoning. This environmental disease, still present in France, is the only notifiable non-infectious disease. Its complications include, in the foreground, disorders of psychomotor development but also include in adults the attack of other systems. The fight against lead poisoning mainly involves the removal of lead sources. Several methods of eviction exist: a modification of the practices, a palliative rehabilitation, a definitive rehabilitation and a relocation. The effectiveness of each method is not documented. This study therefore aims to compare the effectiveness of these various measures to eliminate the risk of exposure to lead on blood lead. This study uses the methodology of a multicenter historical cohort. It will begin in the second quarter of 2017. The research centers will be child-environment consultations and mother-child PASS in Avignon, Manosque, Marseille, Nice and Toulon. The study will be offered to all children monitored in these centers since 2011. The inclusion criteria will include: age \<18 years, at least one blood lead ≥ 50μg.L-1, residence declared in PACA and absence opposition. The retrospective data will be incorporated into the prospective monitoring. The necessary number is at least 165 cases of infantile lead poisoning (of which 33 per type of intervention). The primary endpoint will be the kinetics of quarterly venous blood lead. The smallest clinically significant difference in blood lead levels will be 50μg.L-1 between the different groups. Statistical analysis will use intra- and inter-individual variability analysis by compartmental modeling of the pharmacokinetics of blood lead. An interim analysis will be conducted in 2017 on the retrospective data to confirm the necessary staffing.
