Profile of adverse drug reactions reported via the Continuum+ platform: Results from three-year regional follow-up.

In 2017, the Continuum+ platform was launched to provide a monitoring solution to home-based cancer care patients: AKO@dom monitoring. This platform also offers the follow-up of adverse drug reactions (ADRs) via direct notification to regional centers of pharmacovigilance (RCPVs). According to previous studies, the AKO@dom monitoring has successfully maintained treatment at the maximum effective dosage, managing ADRs and patient satisfaction.

Cross-reactivity among and between macrolides, lincosamides, and streptogramins: Study on the French pharmacovigilance database.

Background: Hypersensitivity reactions (HSR) are reported for the macrolides, lincosamides, and streptogramins (MLS) antibiotic family. Data about cross-reactivity among and between MLS remain scarce or controversial.

Objectives: The aim of this study was to provide an overview of hypersensitivity cross-reactions among MLSs based on data extracted from the French National Pharmacovigilance Database (FPVD).

Adverse drug reaction profile of third-generation smallpox vaccines used in France during the 2022 monkeypox epidemic.

Due to the start of the monkeypox epidemic in 2022, we retrospectively analyzed the adverse drug reactions (ADRs) reported in France after monkeypox vaccinations with the third-generation smallpox vaccine. Ninety-eight cases, representing 172 ADRs, were reported. ADRs were mostly expected reactogenicity reactions occurring within days after the first dose of vaccine and having a quick favorable outcome.

Zoledronate and osteonecrosis of the jaw in osteoporosis: incidence and risk factors. Analysis of the French Pharmacovigilance Database.

Introduction: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) have been characterized with the use of oral bisphosphonates in osteoporosis and zoledronate in oncology. Uncertainties remain, though, with the occurrence of BRONJ related to the use of zoledronate in osteoporosis.

Objectives: We aimed to estimate the incidence and characterize the risk factors of zoledronate-associated BRONJ in osteoporosis as compared with oral bisphosphonates in real life setting.

COVID-19 Vaccination and the Incidence of De Novo or Recurrent Rheumatoid Arthritis: A French and International (VigiBase) Signal Detection Study.

COVID-19 vaccination is critical in frequently immunocompromised patients with rheumatoid arthritis (RA). However, there is a question about the risk of RA flares following vaccination. Our study intended to find out about cases of new RA or flare-ups in people who already had RA that were reported in French and international pharmacovigilance databases after COVID-19 vaccination.

Radiological evolution of progestogen-induced meningioma: A monocentric retrospective study.

Cyproterone acetate (CPA) is known to induce meningioma, and recently, nomegestrol acetate (NMA) and chlormadinone acetate (CMA) were also involved. Progestagen-induced meningioma management starts with progestogen discontinuation and is either interventional (surgery and/or radiotherapy) or conservative (clinical and MRI radiological follow-up). We performed a retrospective volumetric radiological outcomSe study of progestogen-induced meningiomas diagnosed in our hospital.

Drug-induced radiation recall reactions and non-anticancer drugs: A descriptive analysis from VigiBase®.

Radiation recall reactions are inflammatory reactions confined to previously irradiated tissues, often of drug-induced etiology, particularly with anticancer therapies. Other drugs, in particular COVID-19 vaccines, may also be involved. To describe radiation recall reactions under non-anticancer drugs more precisely, we extracted the cases of radiation recall reactions associated with non-anticancer drugs from WHO pharmacovigilance database VigiBase®.

Adverse drug reaction related to drug shortage: A retrospective study on the French National Pharmacovigilance Database.

Aim: Drug shortages are a growing global health issue. The aim of the study was to evaluate the consequences of drug shortages on patient safety based on data recorded in the French National Pharmacovigilance Database.

Methods: All cases involving drug shortages reported from 1985 to the end of 2019 were extracted from the database.

Psoriasis risk after beta-blocker exposure: Description of a pharmacovigilance signal.

Aim: We aimed to investigate French pharmacovigilance data. The objective was to characterize psoriatic conditions that occurred after beta-blocker (BB) exposure and bring to light a possible pharmacovigilance signal.

Methods: Spontaneous reports of psoriatic conditions recorded in the French National Pharmacovigilance Database (FPVD) between 1985 and 2019 were extracted.

Case Report: Severe Hypercalcemia Following Vitamin D Intoxication in an Infant, the Underestimated Danger of Dietary Supplements.

Vitamin D supplementation is routinely introduced in infants, according to medical guidelines. However, vitamin D overdose can result in life-threatening hypercalcemia. We report the case of a 3-month-old infant who suffered from severe hypercalcemia.

Spontaneous reporting of adverse drug reactions as an outlet for patient dismay? The case of Levothyrox® change of excipients.

Following minor changes of excipients of Levothyrox®, the French Pharmacovigilance Database was overwhelmed by patients' spontaneous reports of adverse drug reactions associated with the new formula. After noticing that most of these reports differed from those related to other drugs, we aimed to characterize their features and compared them with spontaneous reports associated with other chronic treatments as comparators. We randomly sampled patient reports associated with either Levothyrox® new formula (n = 200) or comparator drugs (n = 200) from March 2017 till March 2018 from the National Pharmacovigilance Database.

Immune checkpoint inhibitors-induced nephropathy: a French national survey.

Immune checkpoint inhibitors (ICIs), aiming to foster cancer-targeted immune response, proved to be effective in several advanced malignancies at the price of immune-related adverse events affecting various organs, notably the kidneys. Herein, a retrospective descriptive analysis was performed on all biopsy-confirmed cases of ICI-induced nephropathy notified to the French Pharmacovigilance database to date. Data were gathered about patients' characteristics, acute kidney injuries and histopathological features.

Remdesivir and Acute Renal Failure: A Potential Safety Signal From Disproportionality Analysis of the WHO Safety Database.

Remdesivir is approved for emergency use by the US Food and Drug Administration (FDA) and authorized conditionally by the European Medicines Agency (EMA) for patients with coronavirus disease 2019 (COVID-19). Its benefit-risk ratio is still being explored because data in the field are rather scant. A decrease of the creatinine clearance associated with remdesivir has been inconstantly reported in clinical trials with unclear relevance.

Case Report: Successful Treatment of Steroid-Refractory Immune Checkpoint Inhibitor-Related Pure Red Cell Aplasia With Cyclosporin.

Anemia associated with Immune checkpoint inhibitor (ICI) is usually hemolytic and regenerative. Cases of non-regenerative pure red cell aplasia are rare, and typically improve upon drug discontinuation and after corticotherapy. We herein report a case of nivolumab-related erythroblastopenia refractory to steroids in a melanoma patient that improved only after treatment with cyclosporin.

Insights on the Evidence of Cardiotoxicity of Hydroxychloroquine Prior and During COVID-19 Epidemic.

The recent empirical use of hydroxychloroquine (HCQ) in coronavirus disease 2019 (COVID-19) revived the interest in its cardiac toxicity, increasingly sidelined over time. We aimed to assess and compare the profile of cardiac adverse drug reactions (CADRs) associated with HCQ before and during COVID-19. We performed a retrospective comparative observational study using the French Pharmacovigilance network database between 1985 and May 2020 to assess all postmarketing CADRs associated with HCQ notified before COVID-19 in its approved indications for lupus and rheumatoid arthritis (preCOV), and those concerning its empirical use in COVID-19 (COV).

"Off-label" use of hydroxychloroquine, azithromycin, lopinavir-ritonavir and chloroquine in COVID-19: A survey of cardiac adverse drug reactions by the French Network of Pharmacovigilance Centers.

Introduction: COVID-19 is an unprecedented challenge for physicians and scientists. Several publicized drugs are being used with not much evidence of their efficacy such as hydroxychloroquine, azithromycin or lopinavir-ritonavir. Yet, the cardiac safety of these drugs in COVID-19 deserves scrutiny as they are known to foster cardiac adverse ADRs, notably QTc interval prolongation on the electrocardiogram and its arrhythmogenic consequences.

[French trends in the misuse of Fentanyl: From 2010 to 2015].

Objectives: The aim of this study was to evaluate the French use, misuse and abuse/dependence of non-injectable forms of fentanyl (transdermal and transmucosal fentanyl formulations).

Methods: Problematic use of transdermal and transmucosal fentanyl formulations was evaluated using an approach combining multiple sources of information: (1) spontaneous notifications recorded during 6 years (2010-2015) for transdermal fentanyl form and 3 years for transmucosal fentanyl forms and (2) data from annual epidemiological systematic surveys conducted by the French Addictovigilance Network during 6 years (2010-2015).

Results: In all, 147 cases were notified for transdermal fentanyl formulation and 109 cases for transmucosal fentanyl formulations.
