The French National Agency for Health Products (ANSM) is a regulatory and public health agency. Its regulatory, health policing and public health protection activities require a perfect fit with the field and the various people involved in the use of health products. Since 2019, the ANSM has adapted its organisation, procedures and processes to encourage and improve interaction with its stakeholders, as part of its policy of openness towards civil society.

Objective: In recent years, safety concerns about modafinil exposure during pregnancy have emerged. In particular, increased risks for major congenital anomalies (MCA) and impaired fetal growth were reported, although study results were conflicting. Our investigation aims to examine previously reported safety signals.

Lacosamide, a voltage-gated sodium channel inhibitor, is an anti-seizure medication (ASM) from the age of 4. We report on the case of a woman treated with lacosamide for pharmacoresistant epilepsy who breastfed her infant for more than 6 months after birth. The infant's blood concentrations of lacosamide were 2.

Shortages of drugs and medical devices have tended to increase in France and worldwide, with consequences for patients and healthcare professionals. Preventing shortages of health products has become a priority for regulatory authorities, including the French National Agency for Medicines and Health Products Safety (ANSM). To highlight perspectives for a better prevention, we described and analyzed the management of shortages in the availability of health products in France over the last 10 years.

The coronavirus disease (COVID-19) pandemic has caused disruption and uncertainty for junior medical doctor training and education. This has compounded the existing stress experienced by this cohort. However, by choosing appropriate educational models, as well as using novel educational approaches and advancing our online technology capabilities, we may be able to provide acceptable and even, superior solutions for educational training moving forward, as well as promote trainee wellbeing during these uncertain times.

Introduction: The health context with COVID-19 pandemic has led to fast development of many vaccines against the SarS-Cov-2 virus. Four of them are currently available in France and contain polyethylene glycol (PEG) or polysorbate 80 as excipients, already described as causing anaphylaxis. French recommendations have been suggested by allergology authorities and proposed a course of action in the event of a suspected allergy to these vaccines.

The association between vaccines and peripheral facial palsy (PFP), an issue that has been the subject of debate for many years, has been raised again following results of clinical trials assessing mRNA based COVID-19 vaccines. To review the available literature on this topic, PubMed was searched from inception until February 25, 2022. Inclusion criteria were case reports with documented rechallenge and comparative epidemiological studies.

Background And Objective: The concern surrounding the association between Guillain-Barré syndrome (GBS) and vaccination has increased with the widespread use of COVID-19 vaccines. The aim of this study was to assess the potential association of GBS with mRNA-based or adenovirus-vectored COVID-19 vaccines.

Methods: Reports of GBS associated with mRNA-based or adenovirus-vectored COVID-19 vaccines were extracted from the WHO pharmacovigilance database, exposure data from the Our World in Data website, and the background rates of GBS from published data.

Background And Purpose: The EREMI project was set up to collect data on adverse drug reactions (ADRs) occurring due to off-label and/or unlicensed drugs prescribed to hospitalised children in France. These events were evaluated by a regional pharmacovigilance centre (RPC) and an adjudication committee (AC). The aim of this study was to assess the agreement between these two different entities on their evaluation of ADRs.

Mosquito-borne flaviviruses, such as dengue (DENV), Zika (ZIKV), yellow fever (YFV), West Nile (WNV), and Japanese encephalitis (JEV) viruses, threaten a large part of the human populations. In absence of therapeutics and effective vaccines against each flaviviruses, targeting viral metabolic requirements in mosquitoes may hold the key to new intervention strategies. Development of metabolomics in the last decade opened a new field of research: mosquito metabolomics.

Pandemic SARS-CoV-2 causes a mild to severe respiratory disease called coronavirus disease 2019 (COVID-19). While control of the SARS-CoV-2 spread partly depends on vaccine-induced or naturally acquired protective herd immunity, antiviral strategies are still needed to manage COVID-19. Enisamium is an inhibitor of influenza A and B viruses in cell culture and clinically approved in countries of the Commonwealth of Independent States.

Background: Growing evidence indicates that amoxicillin induces herpesvirus replication in vitro. As these play a central pathophysiological role in Drug Reaction with Eosinophilia and Systemic Symptoms syndrome (DRESS), amoxicillin could present with specific DRESS features.

Objective: To characterize the onset patterns of amoxicillin-associated DRESS.

Objective: We aimed to review and analyze studies focusing on the efficacy of metronidazole in reducing the risk of preterm birth and the safety of metronidazole taking into account the different doses, duration of treatment and routes of administration.

Study Designs: Embase, Cochrane Library and PubMed were searched up to 29 July 2019 to identify studies assessing metronidazole exposure during pregnancy. Additional studies were identified from reference lists of retrieved papers.

Article Synopsis
  • The study investigates the connection between off-label drug use and adverse drug reactions (ADRs) in hospitalized children, aiming to enhance understanding of prescribing practices and the impact of such drug use.
  • Utilizing a multicenter prospective design starting in 2013, the research employs French product summaries and various evaluation methods to identify and assess ADRs, ensuring thorough monitoring and validation of findings.
  • While this is a pioneering study with significant patient recruitment and independent evaluation of ADRs, potential limitations include under-reporting and missing data from hospital records which could affect the overall findings.

Dengue virus (DENV) subdues cell membranes for its cellular cycle by reconfiguring phospholipids in humans and mosquitoes. Here, we determined how and why DENV reconfigures phospholipids in the mosquito vector. By inhibiting and activating the de novo phospholipid biosynthesis, we demonstrated the antiviral impact of de novo-produced phospholipids.

Self-medication (SM) is a common practice perceived by patients as harmless which can, however, entail health risks. The aim of the study was to identify drug-drug interactions (DDIs) involving SM drugs leading to adverse drug reactions (ADRs) in the National French Pharmacovigilance Database. All ADR reports from 1 January 1985 to 31 July 312018, coded as 'interaction' and 'self-medication', were selected and studied.
