Factors associated with the use of benzodiazepine and opioid prescription drug in the student population: a cross-sectional study.

The misuse of benzodiazepines and opioid medications is frequent in students. To improve our understanding of this behavior, we aimed to identify factors associated with separate and concomitant use of these substances. Anonymous self-reported questionnaires were e-mailed to students enrolled at a French university between March and July 2021, covering: sociodemographic characteristics, academics, psychoactive substance use, ADHD symptomatology (adulthood and childhood), and psychiatric/psychological or addiction follow-up. Factors associated with the use of benzodiazepines and opioid medications included female sex (OR = 1.41 [1.08; 1.86]) and OR = 1.38 [1.06; 1.79], respectively), older age (OR = 1.65 [1.04; 2.6] and OR = 2.17 [1.4; 3.36], respectively), current psychiatric/psychological follow-up (OR = 6.53 [5.18; 8.24] and OR= 1.5 [1.12; 2.0], respectively), ADHD symptomatology (OR= 2.33 [1.71;3.16] and OR= 1.61 [1.15; 2.24], respectively), polyconsumption (tobacco use for benzodiazepine users, OR = 1.38 [1.04; 1.82]; alcohol use OR = 1.67 [1.17; 2.39] and tobacco use OR = 1.62 [1.23; 2.14] for opioid users). These factors were even more strongly associated with the concomitant use of benzodiazepines and opioid medications: older age (OR = 3.64 [2.22; 5.99]), female sex (OR = 1.54 [1.1; 2.14]), grade repetition (OR = 1.7 [1.14; 2.54]), psychiatric/psychological follow-up (OR = 4.51 [3.35;6.06]), ADHD symptomatology (OR = 5.3 [3.69; 7.63]), polyconsumption (tobacco use OR = 2.05 [1.39; 3] and cannabis use, OR = 2.07 [1.97; 4.16]. The factors associated with the use of benzodiazepines and prescription opioids identified in this study could lead to the development of targeted prevention methods.

Adverse drug effect in the context of drug shortage: the CIRUPT prospective study from the French pharmacovigilance network.

OBJECTIVES: Drug shortages are of increasing concern to worldwide public health. The consequences of drug shortages for patient safety have been little studied, especially from a pharmacovigilance point of view. In this context, the network of French pharmacovigilance centres conducted the CIRUPT study (Conséquences Iatrogènes des RUPTures de stock/iatrogenic consequences of drug shortages) based on a prospective campaign of adverse effects occurring in the context of drug shortage notifications. METHODS: All notifications involving a shortage drug submitted to the French pharmacovigilance centres between 1 January 2020 and 30 June 2021 were collected and registered in the French national pharmacovigilance database with the standardised high level term 'product supply and availability issues' and with predefined keywords in the narrative section. RESULTS: 224 cases were included, involving mainly adverse drug reactions (ADRs) (n=131/224, 59%) and medication errors (n=51/224, 23%); 29% of the cases were serious. The most represented classes of shortage drugs were: vaccines (n=78/224, 35%); drugs for acid-related disorders (H2-receptor antagonists) (n=27/224, 12%); antineoplastic agents (n=17/224, 8%); and antiepileptics (n=15/224, 7%). In 82% of cases, the involved shortage drug was the subject of information delivered to health professionals by the National Agency for the Safety of Medicines and Health Products. Drug shortages were associated with an ADR related to replacement drugs in 59% (n=131/224) of the cases, drug inefficacy in 18% (n=41/224), and/or an aggravation of the underlying disease in 11% (n=25/224). CONCLUSIONS: From a pharmacovigilance point of view, a large diversity of anatomical therapeutic classes is involved and the risk related to drug shortages is not limited to drugs registered on 'major therapeutic interest or essential drug' lists. Information from health agencies is not sufficient to avoid the risks, and further strategies should be developed.

Experimental Models of Posterior Reversible Encephalopathy Syndrome: A Review From Pathophysiology to Therapeutic Targets.

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiological entity characterized by nonspecific symptomatology (eg, headache, visual disturbances, encephalopathy, and seizures) and classically cortical and subcortical vasogenic edema predominantly affecting the parietooccipital region. PRES etiologies are usually dichotomized into toxic PRES (eg, antineoplastic drugs, illicit drugs) and clinical condition-associated PRES (eg, acute hypertension, dysimmune disorders). Although the pathophysiology of PRES remains elusive, 2 main pathogenic hypotheses have been suggested: cerebral hyperperfusion due to acute hypertension and cerebral hypoperfusion related to endothelial dysfunction. Research into the pathogenesis of PRES has emerged through the development of animal models in the last decade. The motivation for developing a suitable PRES model is 2-fold: to fill in knowledge gaps of the pathophysiological mechanisms involved, and to open new perspectives for clinical assessment of pharmacological targets to improve therapeutic management of PRES. All current models of PRES have a hypertensive background, on which other triggers (acute hypertension, inflammatory, drug toxicity) have been added to address specific facets of PRES (eg, seizures). The initial model consisted in inducing a reduced uterine perfusion pressure that mimics preeclampsia, a leading cause of PRES. More recently, a model of stroke-prone spontaneously hypertensive rats on high-salt diet, originally developed for hypertensive small vessel disease and vascular cognitive impairment, has been studied in PRES. This review aims to discuss, depending on the research objective, the benefits and limitations of current experimental approaches and thus to define the desirable characteristics for studying the pathophysiology of PRES and developing new therapies.

An overview of the use of psychoactive substances among students at the University of Lille during the COVID-19 health crisis: Results of the PETRA study.

OBJECTIVES: Students represent a population at risk for substance abuse. That risk may have been exacerbated by the COVID-19 pandemic. We aimed to describe substance abuse among students and to compare consumption according to the university field. METHODS: A self-administered questionnaire was sent by email to all students at the University of Lille, France, between March and July 2021. This anonymous questionnaire included questions about sociodemographic characteristics, university courses and the use of psychoactive substances (frequency, reasons, routes of administration) since the first university year. RESULTS: Among the 4431 students who responded (response rate 6.1%), eighty percent declared having used alcohol since the first university year, 34% cannabis, 15.4% benzodiazepines, 14.7% opioid drugs, 7.5% cocaine, 6.8% nitrous oxide and 6.5% MDMA. More than 20% of the users of cannabis, benzodiazepines, amphetamines and cocaine reported having already felt dependent. Recreational use was described by more than 10% of benzodiazepine or opioid drug users. Nitrous oxide use was significantly more frequent in the health and sport field (p < 0.001). Tobacco, benzodiazepine, cannabis and MDMA uses were significantly more frequent in the humanities and social sciences/art, language and literature fields (p < 0.001). CONCLUSION: Prevention measures focusing on alcohol, cannabis, illicit psychostimulants, nitrous oxide and prescription drugs are required in the student population.

Fosfomycin-induced agranulocytosis: a case report and review of the literature.

BACKGROUND: The intravenous form of fosfomycin, a bactericide antibiotic used to treat multiresistant bacterial infections is little prescribed. The most common reported adverse effects are hypokaliemia and hypernatremia. We describe a case of agranulocytosis, a rarely described side effect that may be fatal. CASE PRESENTATION: A 45 year-old woman was admitted to the intensive care unit for post-surgical meningitis following meningioma resection. Meropenem and vancomycin were first introduced. A DRESS-syndrom with meropenem was suspected. Neutropenia was diagnosed three days after the introduction of parenteral fosfomycin and agranulocytosis four days later. Eosinophilia was also observed. A bone marrow aspiration was performed showing a disappearance of the neutrophil granulocyte line and a significant eosinophilia. Meropenem was discontinued. Fosfomycin was maintained and filgrastim was added. As filgrastim had no effect, the relationship with fosfomycin was suspected, so it was then withheld. An increase of the neutrophil count was observed. Because of the complexity of the case, the unfavorable course of the illness and the urgent need for revision surgery, a rechallenge with fosfomycin was done followed by a decrease of the neutrophil count. CONCLUSION: This is the third paper reporting agranulocytosis induced by fosfomycin, and the first detailed description of a case. Based on chronological and semiological criteria and bibliographic data, the event was qualified as probable with the Naranjo adverse drug probability scale. Literature data is scarce. The summary of product characteristics mentions that only a few cases of transient neutropenia and agranulocytosis have been reported. An analysis of the FDA Adverse Event Reporting System Database highlighted a higher than expected frequency of agranulocytosis in patients treated with fosfomycin. Parenteral fosfomycin is often used in patients receiving other medications, so that it is rarely the only suspect. In our case, the results of the bone marrow aspiration, the sudden drop of the neutrophil count with concomitant eosinophilia and the absence of improvement despite the dose decrease, point towards an immuno-allergic mechanism. However, the overlap between the suspected DRESS induced by meropenem and the agranulocytosis do not allow to conclude with certainty on the causality. Awareness should be raised about this side effect.

Incidence and preventability of hospital admissions for adverse drug reactions in France: A prospective observational study (IATROSTAT).

AIMS: In the last French study in 2007, the incidence of hospital admissions (HAs) related to adverse drug reactions (ADRs) was 3.6%. The objective was to assess the current ADR-HA incidence in France and to describe both its characteristics and preventability. METHODS: A prospective multicentre study was conducted among randomly selected French public hospital medical wards (April-July 2018). Patients admitted during a week period were included. ADR-HA cases were collected by the French Regional Pharmacovigilance Centres network. An independent committee validated potential cases and ADR preventability. RESULTS: ADR-HA incidence was 8.5% (95% confidence interval [CI]: 7.6-9.4%), increasing with age (3.3% [95%CI: 1.8-5.5%] ≤16 y vs. 10.6% [95%CI: 9.3-12.0%] ≥65 y). The most common ADRs were haemorrhagic events (8.8%), haematological disorders (6.5%), acute renal failure (6.3%), fluid and electrolyte disorders (6.0%), and falls (5.2%). New drugs were involved: targeted therapies (22.8% of antineoplastics), direct oral anticoagulants (29.6% of antithrombotics) and incretin-based drugs (20.0% of antidiabetics). ADRs were preventable in 16.1% of cases because the drugs involved had not been used in accordance with monographies, package leaflets or other therapeutic guidelines. The main situations of noncompliance addressed either dose or duration of use (27.9%), warning (23.2%), use precaution (18.6%) and inappropriate self-medication or misuse by patients (11.6%). CONCLUSION: In France, ADR-HA incidence dramatically increased over the last decade. A significant proportion was related to new pharmacological classes and considered as preventable. These findings should lead to in-depth thought on preventive actions on at-risk drug classes.

Doping with aromatase inhibitors and oestrogen receptor modulators in steroid users: Analysis of a forum to identify dosages, durations and adverse drug reactions.

INTRODUCTION: Some users of anabolic androgenic steroids (AAS) secretly consume aromatase inhibitors (AI) and selective oestrogen receptor modulators (SERM). Cyber-forums can be potential sources of information. Our aim was to determine the cycles used, and to identify the adverse drug reactions (ADRs) experienced, reported in a bodybuilding forum. METHOD: We collected discussions on a French forum for AAS users (MESO-Rx®), from January 2013 to 2019 on concerning clomiphene, tamoxifen, anastrozole, exemestane and letrozole were collected. Characteristics of the users, duration of cures, treatments, dosages, point of purchase and occurrence of ADRs were analysed. RESULTS: Among the 1792 posts published on the forum, 845 concerned SERM and 571 concerned AI, i.e. 2180 drugs used (several cycles included concomitant consumption). Our population was exclusively male, with an average age of 28.2±6.3years, and had been practising weight training for 6.7±5.6years. The SERMs were mainly used to "revive the hypothalamohypophyseal axis" and the AIs to "fight against androgen aromatisation". The median treatment duration was 22 days for SERM, 70days for anastrozole, 84days for exemestane and 30days for letrozole, with a mean dose of 69mg/d for clomiphene, 22mg/d for tamoxifen, 0.4mg/d for anastrozole, 10mg/d for exemestane, 2mg/d for letrozole. The main way of obtaining these drugs was through the internet. 157 ADRs were identified: 95 for SERMs and 62 for AI. The most represented were acne, musculoskeletal, mood and reproductive disorders. Impaired quality of life (according to the patient) was described in 54% of the SERM posts and 26% of the AI posts. CONCLUSIONS: Patient narratives posted on forums can be a useful tool in the context of doping, to better understand practices, motivations and possibly to bring up pharmacovigilance signals.

Trends in the delivery of reimbursed nicotine replacement therapies between 2016 and 2019 in France.

OBJECTIVES: Describe the evolution of the expenses and the number of boxes of nicotine replacement therapy reimbursed by the French health insurance between 2016 (flat rate of €.150/year with advance payment) and 2019 (65% reimbursement without in advance payment and without a spending limit). SETTING AND PARTICIPANTS: Descriptive and analytical epidemiological study between January 1, 2016 and December 31, 2019 based on a retrospective collection of data from OpenMEDIC (the merged French health insurances drug claim database) on the number of reimbursed NRT boxes dispensed by community pharmacies and their annual cost. RESULTS: During 4 years, 7.4 million boxes of NRT were reimbursed (total cost of 148.4 million euros): approximately 300,000 in 2016, 650,000 in 2017, 1.9 million in 2018 and 4.6 million in 2019, namely a fifteen-fold increase between 2016 and 2019 (a geometric growth ratio of 2.5 each year). This increase was slightly more pronounced among men than among women, and concerned more NRT delivered from time to time (gums, tablets): transdermal devices proportion decreased from 79.7% of reimbursed NRT in 2016 to 52.9% in 2019, with an increase in gums (8% to 13.3%) and sublingual tablets (8.4% to 15.8%) over the same period. CONCLUSIONS: The evolution of NRT reimbursement comes with an increase in NRT deliveries. This suggests a real medical need rather than a short trend: therefore, this suggests a catch-up in the access to care.

Beneficial effects of atorvastatin on sex-specific cognitive impairment induced by a cerebral microhaemorrhage in mice.

BACKGROUND AND PURPOSES: Cerebral microhaemorrhages (CMHs) are associated with cognitive decline in humans. In rodents, CMHs induces cognitive impairment in male mice along with sex-specific cortical and hippocampal changes affecting neural, glial and vascular functions. Statins, have been proposed to prevent cognitive decline. We tested here the action of atorvastatin on CMH-induced cognitive impairment in a murine model of CMH. EXPERIMENTAL APPROACH: Using a multimodal approach combining behavioural tests, in vivo imaging, biochemistry and molecular biology, the effects of oral administration of atorvastatin on the sex-specific changes induced by a cortical CMH were studied in male and female mice (C57BL/6J) at 6-week post-induction using a collagenase-induced model. KEY RESULTS: Atorvastatin caused specific effects according to the sex-specific CMH-induced changes. In males, atorvastatin improved the visuospatial memory, induced a local modulation of microglial response and enhanced brain-derived neurotrophic factor (BDNF)-tropomyosin receptor kinase B (trkB) and vascular endothelial growth factor (VEGF) expression in the cortex. In the hippocampus, atorvastatin increased glucose metabolism and modulated astrocytes morphology. In females, atorvastatin did not modulate visuospatial memory despite the increased expression of cortical BDNF and the decrease in the number of hippocampal astrocytes. Atorvastatin also induced a decrease in the expression of cortical oestrogen receptors but did not modify body weight nor serum cholesterol levels in both sexes. CONCLUSION AND IMPLICATIONS: Atorvastatin modulated the sex-specific cognitive impairment induced by the CMH with a pathophysiological impact mainly within the cortical area. It could represent a promising candidate for future sex-stratified clinical trials in patients with CMH.

Sex Differences in Cognitive Impairment Induced by Cerebral Microhemorrhage.

It has been suggested that cerebral microhemorrhages (CMHs) could be involved in cognitive decline. However, little is known about the sex-dependency of this effect. Using a multimodal approach combining behavioral tests, in vivo imaging, biochemistry, and molecular biology, we studied the cortical and hippocampal impact of a CMH in male and female mice (C57BL/6J) 6 weeks post-induction using a collagenase-induced model. Our work shows for the first time that a single cortical CMH exerts sex-specific effects on cognition. It notably induced visuospatial memory impairment in males only. This sex difference might be explained by cortical changes secondary to the lesion. In fact, the CMH induced an upregulation of ERα mRNA only in the female cortex. Besides, in male mice, we observed an impairment of pathways associated to neuronal, glial, or vascular functions: decrease in the P-GSK3ß/GSK3ß ratio, in BDNF and VEGF levels, and in microvascular water mobility. The CMH also exerted spatial remote effects in the hippocampus by increasing the number of astrocytes in both sexes, increasing the mean area occupied by each astrocyte in males, and decreasing hippocampal BDNF in females suggesting a cortical-hippocampal network impairment. This work demonstrates that a CMH could directly affect cognition in a sex-specific manner and highlights the need to study both sexes in preclinical models.

TNF-α inhibitors and psychiatric adverse drug reactions in the spectrum of bipolar (manic) or psychotic disorders: Analysis from the French pharmacovigilance database.

OBJECTIVE: This study aimed to describe reports of psychiatric adverse drug reaction (ADR) in the spectrum of bipolar (manic features) or psychotic disorders that occurred under tumor necrosis factor alpha (TNF-α) inhibitors therapy. METHODS: We searched the French pharmocovigilance database for reports of psychiatric ADR in the spectrum of bipolar (manic features) or psychotic disorders during treatment with TNF-α inhibitors. Psychiatric symptoms were divided in 2 categories: (i) confirmed diagnosis of manic episode or acute psychosis and (ii) psychiatric symptoms with psychotic or manic features but not meeting sufficient criteria for diagnosis of psychosis or manic disorder. RESULTS: Overall, 9942 reports of ADR were registered in the French pharmacovigilance database with TNF-α inhibitors, including 243 reports of psychiatric ADR. Among them, we identified 41 reports of psychotic or manic disorders as define above: 9 characterised manic episodes and 32 psychiatric disorders with psychotic or manic features. TNF-α inhibitors were the only medication suspected in 23 reports (56%). The delay between starting TNF-α inhibitors treatment and onset of symptoms varied from hours to years with a median time of 40 days. Psychiatric symptoms improved in 22/23 patients in whom the TNF-α inhibitor was withdrawn. CONCLUSION: Depressive disorders are well-known ADR of TNF-α inhibitors, but we report, here, 41 reports of psychiatric ADR diagnosed as manic or psychotic disorders or in the spectrum of bipolar or psychotic disorders with these treatments. Epidemiological studies are needed to confirm this signal.

Adalimumab and myositis: A case report and review of the French and international Pharmacovigilance Databases.

TNFα inhibitors, including adalimumab, are widely used in inflammatory rheumatologic and bowel diseases. Well-known adverse effects include: opportunistic infections, immunogenicity and new inflammatory manifestations. Myositis is an inflammatory disease, which manifests with muscle symptoms and can be life-threatening. Little is known about drug-induced myositis. We aimed to describe a case of myositis induced by adalimumab and reviewed national and international pharmacovigilance databases for other cases until 01/02/2019. This was a 63 years old woman with Crohn's disease, who developed muscle weakness, and rhabdomyolysis 3 months after starting adalimumab. Diagnosis of myositis was suspected and confirmed with electromyography and muscle biopsy. Improvement in muscle symptoms was observed after stopping adalimumab and starting corticosteroids. Muscular adverse effects are well-known and usually benign with adalimumab. However, five cases of myositis during treatment with adalimumab were registered in French PharmacoVigilance Database (FPVD) with muscle symptoms observed 3 months to 7 years after starting adalimumab. In VigiBaseⓇ, 90 cases of myositis associated with adalimumab with some similar characteristics were registered. When a patient treated with adalimumab complains of muscular symptoms, inflammatory myopathies should be considered. This adverse effect should be mentioned in a 'Summary of Product Characteristics' to alert healthcare professionals.

Psychiatric Adverse Events Associated With Infliximab: A Cohort Study From the French Nationwide Discharge Abstract Database.

INTRODUCTION: Infliximab (IFX) was the first anti-tumor necrosis factor (TNFα) antibody to be used in the treatment of severe chronic inflammatory diseases, such as Crohn's disease and rheumatoid arthritis. A number of serious adverse drug reactions are known to be associated with IFX use; they include infections, malignancies, and injection site reactions. Although a few case reports have described potential psychiatric adverse events (including suicide attempts and manic episodes), the latter are barely mentioned in IFX's summary of product characteristics. The objective of the present retrospective study was to detect potential psychiatric adverse events associated with IFX treatment by analyzing a national discharge abstract database. MATERIALS AND METHODS: We performed an historical cohort study by analyzing data from the French national hospital discharge abstract database (PMSI) between 2008 and 2014. All patients admitted with one of the five diseases treated with IFX were included. RESULTS: Of the 325,319 patients included in the study, 7,600 had been treated with IFX. The proportion of hospital admissions for one or more psychiatric events was higher among IFX-exposed patients (750 out of 7,600; 9.87%) than among non-exposed patients (17,456 out of 317,719; 5.49%). After taking account of potential confounders in the cohort as a whole, a semi-parametric Cox regression analysis gave an overall hazard ratio (HR) [95% confidence interval] (CI) of 4.5 [3.95; 5.13] for a hospital admission with a psychiatric adverse event during treatment with IFX. The HR (95%CI) for a depressive disorder was 4.97 (7.35; 6.68). Even higher risks were observed for certain pairs of adverse events and underlying pathologies: psychotic disorders in patients treated for ulcerative colitis (HR = 5.43 [2.01; 14.6]), manic episodes in patients treated for severe psoriasis (HR = 12.6 [4.65; 34.2]), and suicide attempts in patients treated for rheumatoid arthritis (HR = 4.45 [1.11; 17.9]). DISCUSSION: The present retrospective, observational study confirmed that IFX treatment is associated with an elevated risk of psychiatric adverse events. Depending on the disease treated, physicians should be aware of these potential adverse events.

Moderate-to-severe eosinophilia induced by treatment with immune checkpoint inhibitors: 37 cases from a national reference center for hypereosinophilic syndromes and the French pharmacovigilance database.

A better understanding of immune-related adverse events is essential for the early detection and appropriate management of these phenomena. We conducted an observational study of cases recorded at the French reference center for hypereosinophilic syndromes and in the French national pharmacovigilance database. Thirty-seven reports of eosinophilia induced by treatment with immune checkpoint inhibitors (ICIs) were included. The median [range] time to the absolute eosinophil count (AEC) peak was 15 [4─139] weeks. The median AEC was 2.7 [0.8─90.9] G/L. Eosinophil-related manifestations were reported in 21 of the 37 cases (57%). If administered, corticosteroids were always effective (n = 10 out of 10). Partial or complete remission of eosinophilia was obtained in some patients not treated with corticosteroids, after discontinuation (n = 12) or with continuation (n = 4) of the ICI. The AEC should be monitored in ICI-treated patients. If required by oncologic indications, continuation of ICI may be an option in asymptomatic hypereosinophilic patients, and in corticosteroid responders.

Polypharmacy in older patients: identifying the need for support by a community pharmacist.

BACKGROUND: The community pharmacist is a key player in medication reviews of older outpatients. However, it is not always clear which individuals require a medication review. The objective of the present study was to identify high-priority older patients for intervention by a community pharmacist. METHODS: As part of their final-year placement in a community pharmacy, pharmacy students conducted 10 interviews each with older adults (aged 65 or over) taking at least five medications daily. The student interviewer also offered to examine the patient's home medicine cabinet. An interview guide was developed by an expert group to assess the difficulties in managing and taking medications encountered by older patients. RESULTS: The 141 students interviewed a total of 1370 patients (mean age: 81.5; mean number of medications taken daily: 9.3). Of the 1370 interviews, 743 (54.2%) were performed in the patient's home, and thus also included an examination of the home medicine cabinet. Adverse events were reported by 566 (42.0%) patients. A total of 378 patients (27.6%) reported difficulties in preparing, administering and/or swallowing medications. The inspections of medicine cabinets identified a variety of shortcomings: poorly located cabinets (in 15.0% of inspections), medication storage problems (21.7%), expired medications (40.7%), potentially inappropriate medications (15.0%), several different generic versions of the same drug (19.9%), and redundant medications (20.4%). CONCLUSIONS: In a community pharmacy setting, high-priority older patients for intervention by a community pharmacist can be identified by asking simple questions about difficulties in managing, administering, taking or storing medications.

Drug-induced osteoporosis/osteomalacia: analysis in the French and Spanish pharmacovigilance databases.

INTRODUCTION: Osteomalacia and osteoporosis are two metabolic bone disorders that increase the risk of fracture due to several causes. In terms of drugs, apart from corticosteroids, which are known to induce bone disorders, several other drugs used in chronic disease management have also been linked with an increased risk of osteoporosis and osteomalacia. PURPOSE: The aim of this study was to describe spontaneous reports of drug-induced osteoporosis and osteomalacia in the French (FPVDB) and Spanish (SPVDB) pharmacovigilance databases. METHODS: Data were provided by the FPVDB and SPVDB. All reports of osteoporosis and osteomalacia recorded from 1985 up to 31 December 2015 inclusive were selected. Taking the time to onset of bone loss into account, all cases occurring in less than 1 month were excluded. RESULTS: A total of 369 reports (44 cases of osteomalacia, 325 cases of osteoporosis) were registered in the FPVDB and 64 (22 cases of osteomalacia, 42 cases of osteoporosis) in the SPVDB. In France, the top 5 drugs involved in the onset of osteoporosis were corticosteroids accounting for approximately half of the reports (n = 170) followed by systemic antiviral (n = 87), antacid (n = 29), antiepileptic (n = 27) and antithrombotic (n = 24) drugs. The 2 main classes of drugs implicated in osteomalacia were systemic antiretroviral drugs for half of the reports (n = 21) and antiepileptic drugs (n = 15). In Spain, corticosteroids were involved in 35.7% of reported cases of osteoporosis (n = 15) followed by systemic antiviral drugs (n = 12). There was no spontaneous report for antacid drugs. For osteomalacia, the 2 main drug classes were systemic antiretroviral drugs (n = 18, 81.8%) followed by antiepileptics (n = 2, 9.0%). In both countries, concomitant administration of systemic corticosteroids with other suspected drugs did not significantly modify the time to onset of drug-induced osteoporosis. CONCLUSION: Despite some differences between the French and Spanish PVDBs, our data consistently show that bone loss is not only restricted to glucocorticoids but also involves antivirals, antiepileptic drugs, antacid drugs or antidepressants. Further analysis might prove useful in exploring the characteristics of drug-induced bone loss on a larger scale.

Pregnancy outcomes in women exposed to cancer chemotherapy.

PURPOSE: There is little data on the effects of cancer chemotherapy in pregnant women. The objective of this study was to describe pregnancy outcomes of women exposed to cancer chemotherapy, recorded in the French Terappel database. METHODS: We performed a descriptive, prospective study of the pregnancies of women exposed to cancer chemotherapy recorded in Terappel between June 1984 and December 2016. Terappel is a French database that has recorded questions of health professionals and/or individuals at the Regional Pharmacovigilance Centres about drugs and pregnancy. For each question, pregnancies are monitored and the outcome is recorded in the database. RESULTS: In total, 75 questions about "anti-cancer drugs and pregnancy" received by 16 Regional Pharmacovigilance Centres between 1997 and 2016 were recorded in Terappel. Breast cancer accounted for 62.7% of the cases, followed by leukaemia (13.3%) and lymphoma (9.3%). Cyclophosphamide is the leading anti-cancer drug with 40.0% of exposed pregnant women, followed by 5-fluorouracil (34.7%), epirubicin (32.0%), tamoxifen (26.7%), and doxorubicin (16.0%). Among the 75 pregnancies, we observed 55 births with 57 children (73.3%) (two cases of twins), nine medical terminations of pregnancy (12.0%), six voluntary terminations of pregnancy (8.0%), three intrauterine foetal deaths (4.0%), and two miscarriages (2.7%). We found a malformation rate of 7.8%. Sixteen of 57 (28.1%) newborns developed one or more neonatal pathologies. CONCLUSION: Pregnancy of women taking anti-cancer drugs resulted in birth in 73% of cases. Nevertheless, pregnant women exposed to cancer chemotherapy remains at risk of malformations and neonatal conditions related to prematurity and drugs.

Acute kidney injury after high dose etoposide phosphate: A retrospective study in children receiving an allogeneic hematopoetic stem cell transplantation.

BACKGROUND: Etoposide phosphate (EP; single injection, 60 mg/kg) followed by total body irradiation (TBI) at 12 Gy has been used as an allogeneic stem cell transplantation (allo-SCT) conditioning regimen for children since 2010. In our institution, EP has been suspected of leading to acute nephrotoxicity. The aim of this study was to assess the potential renal toxicity of EP in this context. MATERIALS AND METHODS: A retrospective study was carried out on children hospitalized between 2007 and 2015 for allo-SCT with TBI-based myeloablative conditioning associated with cyclophosphamide (CY, 60 mg/kg/day × 2 days) or EP. The primary endpoint of the study was the occurrence of acute kidney injury (AKI). Additional endpoints were time to recovery for children with AKI, survival, and treatment-related mortality. RESULTS: Thirty-five patients were analyzed (CY: 22 vs. EP: 13). AKI occurred more frequently in the EP group than in the CY one (69% vs. 27%, adjusted odds ratio 6.0, 95% confidence interval [CI] [1.145; 31.445], P = 0.03). The median time to recovery was estimated at 3 days, 95% CI (2; 17), with CY and 11 days 95% CI (5; 18) with EP (adjusted hazard ratio of recovery for EP vs. CY 0.262, 95% CI [0.071; 0.969], P = 0.04). No significant difference was highlighted between the two treatments for survival or for treatment-related mortality. DISCUSSION: This study shows that EP at high dosage or one of its excipients is probably responsible for AKI, as compared to CY. Further studies are required to explore the origin of this adverse effect.
