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

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.

Efficacy of Ivermectin in COVID-19

SafetySARS-CoV2 Infection2 more

The newly emerged corona virus disease 2019 (COVID-19) has spread to all over the world, with recent estimates of more than 236 million cases diagnosed and led to 4.8 million deaths as November 20211 .Therapeutic approaches are needed to improve outcomes in patients with COVID-19 since no antiviral agent has yet been proved to be conclusively beneficial in COVID-19 infection,especially in patients with mild to moderate degree of severity There has been growing interest in the anti-parasitic drug,ivermectin, which previously was studied as an antiviral, anti-inflammatory and anti-cancer actions2 .It was also reported to have an in-vitro activity against SARS-CoV-23 .Its antiviral properties was due to the action on importin 2/1 mediated nuclear transport. Ivermectin prevents the binding of viral proteins to importin 2/1 rendering the viral proteins unable to enter the nucleus and cause infection4. Several clinical studies have found a beneficial effect of ivermectin in COVID-195-9 However, some study did not find significant difference between the patient group receiving ivermectin and control group10 .Until now, the controlled trials evaluating ivermectin in COVID-19 are lacking. Ivermectin is safe, with reported side effect of less than 1%. Hence it is essential to conduct a clinical trial with ivermectin in patients with COVID-19 .The objective of this study is to establish the efficacy of ivermectin for COVID-19 patients with mild to moderate disease, compare to usual case alone.

Open Label Study of Alacramyn® in Pediatric Patients With Scorpion Sting Envenomation

Scorpion Sting Envenomation

There is no FDA approved therapy for the treatment of scorpion envenomation in the United States. Centruroides scorpion envenomation produces a pattern of neurotoxicity with a spectrum of severity ranging from trivial to life threatening. Patients stung by Centruroides scorpions develop a clinical syndrome which may require sedation with benzodiazepines and observation for 6 to 28 hours of intensive care monitoring. A safe therapy is necessary to halt the progression of symptoms early in the clinical course while avoiding the clinical deterioration that can occur en route to a tertiary facility. Alacramyn® is anticipated to be safer and more effective than the present standard of care in the United States, midazolam, and faster-acting thus eliminating the need to transport most rural patients and reducing hospitalization time.

Selenium in the Treatment of Arsenic Toxicity and Cancers

Arsenical MelanosisArsenical Keratosis5 more

Context: Approximately 100 million people throughout the world consume water contaminated with arsenic at levels above carcinogenic thresholds, including 40 million in Bangladesh alone, with up to one-fourth of deaths attributed to arsenic exposure in the worst-affected regions. There are no proven therapies for treating chronic arsenic toxicity or for preventing arsenical cancers. Selenium has been known to counter arsenic toxicity in a variety of animal models. The investigators have recently shown in animals and humans that this effect is mediated by the formation of [(GS)2AsSe]- , the seleno-bis(S-glutathionyl) arsinium ion, which is then rapidly excreted via the hepatobiliary system. Concurrently, two Phase II studies in China and Bangladesh have suggested clinical benefit to selenium supplementation in arsenicosis patients. Objective: To assess whether daily selenium supplementation counters arsenic toxicity in patients exposed to drinking water arsenic. If proven effective, selenium supplementation might be safely and cost-effectively implemented in the worst-affected localities.

Non-invasive Airway Management of Comatose Poisoned Emergency Patients

PoisoningConsciousness2 more

A decreased level of consciousness is a common reason for presentation to the emergency department (ED) and is often the result of intoxication (up to 1% of all ED visits and 3% of ICU admission). In France, approximately 165 000 poisoned patients are managed each year. Originally developed in head injured patients, the Glasgow Coma Scale (GCS) is a validated reproducible score evaluating the level of consciousness: a GCS ≤ 8 is strongly associated with reduced gag reflex and increased incidence of aspiration pneumonia. Although recommended for patients with traumatic brain injury and coma, it remains unknown whether the benefit of an invasive management of airways with sedation, intubation and mechanical ventilation should be applied to other causes of coma in particular for acute poisoned patients. The investigator hypothesize that a conservative management with close monitoring without immediate endotracheal intubation of these patients is effective and associated with less in-hospital complications (truncated at 28 days) compared to routine practice management (in which the decision of immediate intubation is left to the discretion of the emergency physician).

Therapy of Toxic Optic Neuropathy Via Combination of Stem Cells With Electromagnetic Stimulation...

Methanol PoisoningToxic Optic Neuropathy2 more

The axons of the retinal ganglion cells combine to form the optic nerve. The optic nerve transmits electrical signals to the visual cortex by various synapses. Optic nerve axons are more sensitive to toxins than retina because they are outside the blood retinal barrier. Methanol, various solvents and heavy metals, carbon dioxide, antiarrhythmic, antiepileptic, antibiotics and some vasoactive drugs can cause toxic optic neuropathy. There is a different pathophysiology for each toxin. Methanol is easily accessible alcohol in all types of disinfectants. Methanol is converted into formaldehyde and formic acid while metabolized in the liver. Formaldehyde disrupts ATP synthesis by blocking mitochondrial function and oxidative phosphorylation. Formic acid causes demyelination as a result of metabolic acidosis. Neuroinflammation occurs when denatured proteins block axoplasmic flow. All these processes can lead to apoptosis and permanent vision loss. Sildenafil is a vasoactive drug used in erectile dysfunction. Sildenafil decreases optic nerve head blood flow. Neuroinflammation develops secondary to the cessation of axoplasmic flow after hypoxia. If hypoxia and neuroinflammatiom persists, apoptosis and permanent vision loss develop. Amiodarone is an ion channel blocker used in the treatment of cardiac arrhythmias. Long-term use may cause disruption of ion channel balance in the optic nerve. This condition leads to asymmetric neuroinflammation and apoptosis. Wharton's jelly derived mesenchymal stem cells (WJ-MSC) can increase mitochondrial ATP synthesis with paracrine effects and suppress neuroinflammation with immunomodulatory effects. Repetitive electromagnetic stimulation (rEMS) can rearrange ion channel balances and axoplasmic flow. The aim of this prospective phase-3 clinical study is to investigate the effect of WJ-MSC and rEMS combination in the therapy of toxic optic neuropathies. This combination is the first study in the literature for the therapy of toxic optic neuropathies.
