RESUMEN
The aim of this study was to assess the prevalence and the burden of difficult-to-treat primary ITP (pITP), defined by the need for another ITP treatment after romiplostim and eltrombopag. Adult patients were selected in the prospective, real-world CARMEN-France registry up to December 2021. Out of 821 adult patients with pITP, 29 had difficult-to-treat ITP (3.5%; 95% confidence interval [CI]: 2.3%-4.8% in total; 7.6%; 95% CI: 4.9%-10.2% of patients needing ≥2nd line treatment). The 3-year cumulative incidence of bleeding, infection and thrombosis was 100%, 24.1% and 13.8% respectively. The median cumulative duration of hospital stays was 31 days (median follow-up: 30.3 months).

Vaso-occlusive episodes (VOEs) are a major concern in patients with sickle cell disease (SCD). Exposure to systemic corticosteroids has been suspected to increase the occurrence of VOEs in case reports or series. No comparative study has been conducted to investigate this risk, which is still debated. Several clinical trials demonstrated the effectiveness of corticosteroids for the treatment of VOEs, but with increased rates of readmission. The aim of the study was to assess the risk of hospitalization for VOE associated with exposure to systemic corticosteroids in patients with SCD. We used a case-case-time-control design in a nationwide population-based cohort built in the French national health insurance database between 2010 and 2018. The population included all patients with SCD with at least 1 hospitalization for VOE. Corticosteroids were identified using out-of-hospital dispensing data. The outcome was the first hospitalization for VOE. The case-case-time-control design induces self-adjustment for time-invariant confounders, including genotype. Analyses were adjusted for time-dependent confounders (infections, red blood transfusions) and stratified by exposure to hydroxyurea. Overall, 5151 patients were included in the main analysis. Corticosteroid exposure was significantly associated with the occurrence of hospitalizations for VOEs: adjusted odds ratio, 3.8; 95% confidence interval [CI], 2.4-5.6). In patients exposed to hydroxyurea, the adjusted odds ratio was 2.6 (95% CI, 1.1-6.4); it was 4.0 (95% CI, 2.5-6.3) in unexposed patients. These results were consistent in children and adults. In conclusion, systemic corticosteroids were associated to an increased risk of hospitalization for VOEs and should be limited in patients with SCD.

AIMS: Alzheimer's disease and related diseases (ADRD) is a progressive and inexorable disease. In France, acetylcholinesterase inhibitors and memantine were reimbursed for subjects with ADRD, until 2 modifications of their reimbursement rate (2012, 2018). We aimed to study the consequences of these measures on ADRD subjects' healthcare use. METHODS: We analysed data from the FRA-DEM cohort, including subjects with presumed incident ADRD identified since 2011 in the French health insurance system. We studied the healthcare use of subjects identified with incident ADRD in 2011, 2013, 2015, 2017 and 2019, notably the annual number of defined daily doses of various psychotropic groups. We performed 2 multivariate multinomial logistic regressions with the subcohort year as the dependent variable. RESULTS: In total, 165 120 subjects were included. A progressive decrease in exposure to antidementia drugs was observed between 2011 and 2019. Consultations with private neurologists or psychiatrists, and exposure to risperidone, antidepressants and benzodiazepines increased in the 2019 subcohort, following the 2018 reimbursement withdrawal. Meanwhile, the use of nursing/allied healthcare and emergency care increased over the subcohort years, whereas we observed a decrease in general practitioner consultations. CONCLUSION: These results suggest increases in private neurologist or psychiatrist consultations and exposure to recommended drugs after the reimbursement withdrawal, contrary to the fears expressed. However, antidementia drug exposure decreased long before the reimbursement modifications, probably due to the growing evidence of the modest effect of these drugs, and exposure to benzodiazepines increased after the reimbursement withdrawal.
RESUMEN
BACKGROUND: Healthcare use patterns preceding a diagnosis of Alzheimer's Disease and Related Diseases (ADRD) may be associated with the quality of healthcare use trajectories (HUTs) after diagnosis. We aimed to identify determinants of future favorable HUTs, notably healthcare use preceding ADRD identification. METHODS: This nationwide retrospective observational study was conducted on subjects with incident ADRD identified in 2012 in the French health insurance database. We studied the 12-month healthcare use ranging between 18 and 6 months preceding ADRD identification. The five-year HUTs after ADRD identification were qualified by experts as favorable or not. In order to take into account geographical differences in healthcare supply, we performed mixed random effects multilevel multivariable logistic regression model to identify determinants of future favorable HUTs. Analyses were stratified by age group (65-74, 75-84, ≥ 85). RESULTS: Being a woman, and preventive and specialist care preceding ADRD identification increased the probability of future favorable HUT, whereas institutionalization, comorbidities, medical transportation and no reimbursed drug during [-18;-6] months decreased it. Besides, some specificities appeared according to age groups. Among the 65-74 years subjects, anxiolytic dispensing preceding ADRD identification decreased the probability of future favorable HUT. In the 75-84 years group, unplanned hospitalization and emergency room visit preceding ADRD identification decreased this probability. Among subjects aged 85 and older, short hospitalization preceding ADRD identification increased the probability of future favorable HUTs. CONCLUSION: Regular healthcare use with preventive and specialist care preceding ADRD identification increased the probability of future favorable HUTs whereas dependency decreased it.

BACKGROUND: Several studies have focused on the use of triptan and the risk of acute vascular events but the existence of such association is still debated and has never been quantified in patients over 65 years. To assess whether triptan use among older is associated with an increased risk of hospitalization for acute vascular events. METHODS: A propensity score-matched cohort study was designed using the French national health insurance database linked to hospital stays. Patients aged ≥ 65 years, newly treated by triptans between 2011 and 2014, were included The primary event was hospitalization for an acute ischemic vascular event within de 90 days following triptan initiation. Association with triptan exposure was investigated through cox regression model, considering exposure at inclusion, and with exposure as a time-varying variable A case-crossover (CCO) and a self-controlled case series (SCCS) analyses were also conducted to address potential residual confounding. RESULTS: The cohort included 24, 774 triptan users and 99 096 propensity matched controls (mean (SD) age: 71 years (5.9), 74% of women). Within 90 days after cohort entry, 163 events were observed in the triptan group, and 523 in the control group (0.66% vs. 0.53%, adjusted hazard ratio (aHR) exposed/not exposed 1.25 95%CI [1.05-1.49]; aHR time-varying 8.74 [5.21-14.66]). The association was significant (CCO) for all events (adjusted odds ratio (aOR1.63 [1.22-2.19]) with a more consistent association with cerebral events (aOR 2.14 [1.26-3.63]). The relative incidence (RI) for all events was 2.13 [1.76-2.58] in the SCCS, for cardiac (RI: 1.67 [1.23-2.27]) and for cerebral events (RI: 3.20, [2.30-4.45]). CONCLUSION: The incidence of acute vascular events was low among triptan users. We found that triptan use among older may be associated with a low increased risk for acute vascular events, which may be more marked for cerebral events such as stroke, than for cardiac events.

AIMS: Pharmacovigilance signals of heart failure (HF) following exposure to protein kinase inhibitors (PKIs) have been detected in recent years. Our aim was to identify the PKIs most frequently associated with the development of HF. METHODS: Using the French National Healthcare Database, all patients newly exposed to a PKI between January 2011 and June 2014 were followed up for 18 months. Specific hospitalization diagnosis and long-term HF-related disease codes were used to identify HF patients. HF incidence rate ratios (IRRs) were measured and adjusted hazard ratios (aHRs) were estimated using a Cox model. Sensitivity analyses were performed to limit the potential indication and competitive risk bias. RESULTS: Thirteen PKIs were studied. Among the 49 714 new PKI users registered during the study period, the mean IRR of HF was 3.38 per 100 person-years, with a median time to onset of 155 days. We found a significant increase in the incidence of HF for six medicinal products: pazopanib (aHR = 2.42, 95% confidence interval [CI] 1.67-3.52), dasatinib (aHR = 2.22, 95% CI 1.42-3.44), ruxolitinib (aHR = 2.11, 95% CI 1.69-2.64), crizotinib (aHR = 1.71, 95% CI 1.07-2.72), everolimus (aHR = 1.45, 95% CI 1.26-1.67) and vemurafenib (aHR = 1.37, 95% CI 1.01-1.86). Sensitivity analyses were consistent with our primary analysis. CONCLUSIONS: The current study provides knowledge on HF following exposure to a PKI. Additional studies could confirm these results for dasatinib, everolimus, pazopanib and ruxolitinib, and particularly for the two medicinal products with results slightly above the significance threshold, namely, crizotinib and vemurafenib, in our sensitivity analyses.

PURPOSE: Pharmacokinetic interactions exist between apixaban or rivaroxaban, and CYP3A4 and P-glycoprotein inhibitors such as amiodarone, verapamil and diltiazem. We aimed to estimate the prevalence of exposure to this drug-drug association (DDA) and to assess the bleeding risk associated in patients with atrial fibrillation (AF). METHODS: We conducted a cohort study using a representative 1/97th sample of the French healthcare insurance database between 2014 and 2019. Patients with AF receiving apixaban or rivaroxaban were included and followed-up until hospitalization for bleeding, death, discontinuation of apixaban or rivaroxaban, exposure to strong CYP3A4 inhibitor, or until December 31st 2019, whichever came first. Primary outcome was hospitalization for bleeding registered as primary diagnosis. The association between the exposure to the DDA and hospitalization for bleeding was evaluated as a time-dependent variable in Cox model. RESULTS: Between 2014 and 2019, the AF population under apixaban or rivaroxaban represented 10,392 patients. During the study period, the annual average prevalence of DDA exposure in this population was 38.9%. Among the 10,392 patients, 223 (2.1%) were hospitalized for bleeding, of which 75 (33.6%) received the association and 148 (66.4%) received apixaban or rivaroxaban alone. There was no association between DDA exposure and risk of hospitalization for bleeding (aHR = 1.19, [95% CI: 0.90, 1.58]). Age (HR 1.03 [1.02, 1.05]) and male gender (HR 1.72 [1.28, 2.30]) were associated with an increased risk of hospitalization for bleeding. CONCLUSION: Exposure to antiarrhythmic drugs was not associated with an increased risk of hospitalization for bleeding in patients with AF under rivaroxaban or apixaban.

OBJECTIVES: A frequent late Alzheimer's Disease and Related Diseases (ADRD) identification is described and may induce erratic health resource use. We aimed to describe healthcare use patterns preceding ADRD identification. METHODS: We studied persons aged 65 or older, identified with incident ADRD in 2012 in the French health insurance database. Healthcare use covering a wide range of care in ambulatory and hospital settings during the period ranging from 18 to six months before ADRD identification was studied. The main dimensions of healthcare use patterns before ADRD identification were investigated in three age groups (65-74, 75-84, ≥85) through a multiple correspondence analysis. These dimensions were secondarily interpreted according to the 5-year healthcare trajectory following ADRD identification, qualified as favorable (or not) by experts in the field. RESULTS: This research studied 36,990 subjects. Four dimensions raised in each age group. Two dimensions' interpretations were retrieved in all age groups: intensity of healthcare use, functional dependency. However, their rank differed along with the qualification of the future healthcare trajectory. Some specificities appeared in some age group. In the 65-74 and 75-84 years groups, there were dimensions reflecting healthcare use related to psychiatric or psycho-behavioral disorders. In the ≥85 group, two dimensions reflected dependency related to other comorbidities, and organised medical follow-up. CONCLUSION: Several dimensions emerged in line with erratic trajectories before ADRD identification. They underlined the need for actions towards ADRD identification.

Ketamine and dextromethorphan are widely abused psychoactive substances. Inhibition of N-methyl-d-aspartate receptors (NMDARs) results in neurobehavioural effects including hallucinations, "out of body" sensations and dissociative effects. However, little is known about a possible extended addictive class effect linked to pharmacologically-related amino-adamantane derivatives (e.g., amantadine and memantine). Using a quasi-Bayesian analytic method, we investigated the potential association between the use of approved NMDAR antagonists (i.e., dextromethorphan, ketamine, amantadine and memantine) and the reporting of drug abuse and dependence in the WHO pharmacovigilance database (VigiBase®), which includes >21 million individual case safety reports collected from >130 countries. This disproportionality analysis identified a significant association for all investigated drugs: dextromethorphan (IC = 3.03 [2.97-3.09]), ketamine (IC = 1.70 [1.57-1.83]), amantadine (IC = 0.21 [0.06-0.35]) and memantine (IC = 0.27 [0.13-0.40]), suggesting a class effect for drug abuse and dependence. This first signal requires further investigations, but health professionals need to be alert to the potential of abuse of NMDAR antagonists, especially in the current "opioid epidemic" context, due to their growing interest as non-opioid antinociceptive drugs.

AIMS: The French Ministry of Health scheduled opioid cough suppressants as prescription-only drugs on 12 July 2017. The present study assessed the impact of this regulation on the diversion modalities of the concerned drugs and the related drug pholcodine by analysing the national OSIAP (Ordonnances Suspectes Indicateur d'Abus Possible) database. METHODS: Medical prescriptions with at least 1 mention of codeine, dextromethorphan, ethylmorphine, noscapine or pholcodine for cough suppression recorded in 2013-2019 were extracted from OSIAP. Annual mentioning rates were estimated by dividing numbers of mentions over those of prescriptions recorded the year considered. A descriptive analysis compared the characteristics of prescriptions before and after 12 July 2017. RESULTS: Overall, 832 mentions of the requested drugs were retrieved on 827 prescription forms. Codeine was the most frequent (n = 809, 8.7%) with 6 additional mentions of codeine/ethylmorphine combination, followed by dextromethorphan (n = 11, 0.1%) and pholcodine (n = 6, 0.1%). There was no mention of noscapine. Annual mentioning rates varied between 0 and 0.3% for all drugs except codeine. Codeine mentioning rates ranged between 0.3% (n = 2) and 0.7% (n = 9) before 12 July 2017 and increased to 10.1% (n = 61) thereafter in 2017, 16.1% (n = 314) in 2018, and 19.8% (n = 414) in 2019. The profile of subjects evolved accordingly with an increased male/female ratio (10.0 vs. 1.5 before) and decreased age (23 vs. 40 y before, P < .001). DISCUSSION: The sharp increase of recourse to falsified prescription forms indicates that codeine diversion continues despite restricted access, whereas the other drugs studied do not seem to have been impacted.

AIMS: A better knowledge of opioid prescribing patterns would help to identify areas of potential improvement in cancer pain management. This study aimed to identify potential inappropriate use (PIU) of strong opioid analgesics in cancer outpatients in their last year of life. METHODS: A retrospective cohort of cancer patients who died between 2011 and 2014 and were exposed as outpatient to a strong opioid analgesic in the last year of life was identified in the Echantillon Généraliste de Bénéficiaires (a 1/97th random sample of the French general population). Prescribing patterns of strong opioids were analysed and PIU was defined by at least 1 of these criteria: overlapping prescriptions; contraindicated prescriptions; lack of laxatives; potential drug interactions; prescription in patients hospitalized for opioid-related disorders. Factors associated with PIU were investigated through a multiple logistic regression model. RESULTS: One third of the 2236 patients (median age 72 years [interquartile range: 61-82], 44.1% women) presented a PIU (insufficient laxative prescription [19.6% of patients], insufficient background treatment with transmucosal fentanyl [14.8%], overlapping prescriptions [2.6%]). The rate of PIU significantly decreased from 37.6% (2011) to 29.8% (2014). For patients with a duration of opioid use ≥3 months, factors associated with PIU were fentanyl prescription (adjusted odds ratio = 2.36; 95% confidence interval [1.86-3.00]) and previous use of strong opioid (adjusted odds ratio = 1.88; [1.50-2.36]). CONCLUSION: In France, 1/3 of cancer patients exposed to strong opioids experienced PIU and this proportion tended to decrease over time. There is still room for progress in cancer pain management at the end of life.

AIMS: The aim of this paper is to assess recent developments in non-medical tramadol use, tramadol use disorder, illegal procurement and deaths. METHODS: This study used repeated cross-sectional analysis of data collected nationwide from 2013 to 2018. Analysis was conducted through multisource monitoring of the French Addictovigilance Network of: (1) validated reports of high-risk tramadol use, (2) record systems collecting information from toxicology experts investigating analgesic-related deaths (DTA) and deaths related to substance abuse (DRAMES), and pharmacists for forged prescriptions (OSIAP), and (3) survey of drug users, with investigation of patterns of use while visiting addiction-specialised institutions (OPPIDUM). RESULTS: Despite a plateauing level of tramadol exposure in the French population, the proportion of tramadol reports increased 1.7-fold (187 cases in 2018, 3.2% (95% confidence interval [CI]: 2.74-3.63%), versus 1.9% (95% CI: 1.49-2.42% in 2013). Trends were similar in OSIAP: 11.9% of forged prescriptions in 2018 (95% CI: 10.56-13.45%); 1.7-fold increase; in OPPIDUM: 0.76% (95% CI: 0.55-1.02); 2.2-fold increase; and DRAMES: 3.2% of drug abuse-related deaths in 2018 (95% CI: 1.89-5.16) versus 1.7% in 2013 (95% CI: 0.65-3.84). Tramadol was the primary opioid in analgesic-related deaths in DTA (45% in 2018). Two profiles of high-risk tramadol users were identified: (1) patients treated for pain or with tramadol persistence when pain disappeared (mainly women; mean age 44 years), and (2) individuals with non-medical use for psychoactive effects (mainly men; mean age 36 years). CONCLUSION: The triangulation of the data obtained through addictovigilance monitoring evidenced a recent increase in high-risk tramadol use. These findings have a practical impact on the limitation of the maximal duration of tramadol prescriptions.

INTRODUCTION: With the increase in life expectancy of the population, the progression of chronic diseases, in particular cardiovascular diseases, neurodegenerative diseases (NDD) and their complications, health and medico-social care represents a major public health issue. OBJECTIVE: The aim of this article is to present an overview of the situation of the elderly and the current organization of the healthcare system for their care in French Guiana. METHOD: A review of the literature and analysis of the most recent data related to demographics, socioeconomics, morbidity and mortality, supply and use of care, were carried out. For comparative purposes, these data were compared with those for mainland France and the other French overseas departments and regions when available. RESULTS: With an average annual growth rate of +6.7% among people aged 65 and over, the highest in France (excluding Mayotte), the aging phenomenon has begun in French Guiana, although its population is still young. The health status of the elderly in French Guiana, characterized by an early onset of dependency and a greater prevalence of silent diseases (arterial hypertension, diabetes, hypercholesterolemia), is less favorable than in mainland France. In addition, the health and medico-social provision for the elderly remain incomplete or even embryonic, with little adapted support for elderly people with NND. CONCLUSION: This review highlights the situation of elderly people and the challenges for the health system.
Introduction: Avec l'allongement de l'espérance de vie de la population, la progression des maladies chroniques, notamment des maladies cardioneurovasculaires, maladies neurodégénératives (MND) et leurs complications, la prise en charge sanitaire et médico-sociale représente un enjeu majeur de santé publique. Objectif: Cet article a pour objectif de présenter un état des lieux de la situation des personnes âgées (PA) et de l'organisation actuelle du système de santé pour leur prise en charge en Guyane. Méthode: Une revue de la littérature et l'analyse de données démographiques, socioéconomiques, de morbidité et de mortalité, d'offre et de recours aux soins les plus récentes ont été réalisées. À des fins de comparaison, ces données ont été confrontées avec celles de la France hexagonale et des autres départements et régions d'outre-mer lorsque celles-ci étaient disponibles. Résultats: Avec un taux d'accroissement annuel moyen de +6,7 % chez les 65 ans et plus le plus élevé de France (hors Mayotte), le phénomène de vieillissement est amorcé en Guyane, bien que sa population reste encore jeune. L'état de santé des PA en Guyane, caractérisé par une entrée en dépendance précoce et une plus grande prévalence des maladies silencieuses (hypertension artérielle, diabète, hypercholestérolémie), est moins favorable qu'en France hexagonale. De plus, l'offre sanitaire et médico-sociale pour les PA reste lacunaire, voire embryonnaire, avec peu d'accompagnement adapté pour PA atteintes de MND. Conclusion: Cet état des lieux met en exergue la situation des PA et des enjeux pour le système de santé.

We aimed to assess the risk factors of venous thrombosis (VT) and arterial thrombosis (AT) in adults with primary immune thrombocytopenia (ITP), particularly in relation to treatments. The population comprised all incident primary ITP adults in France between 2009 and 2017 (FAITH cohort; NCT03429660) built in the national health database. Outcomes were the first hospitalisation for VT and AT. Multivariable Cox regression models included baseline risk factors, time-varying exposure to ITP drugs, splenectomy and to cardiovascular drugs. The cohort included 10 039 patients. A higher risk of hospitalisation for VT was observed with older age, history of VT, history of cancer, splenectomy [hazard ratio (HR) 3·23, 95% confidence interval (CI) 2·26-4·61], exposure to corticosteroids (HR 3·55, 95% CI 2·74-4·58), thrombopoietin-receptor agonists (TPO-RAs; HR 2·28, 95% CI 1·59-3·26) and intravenous immunoglobulin (IVIg; HR 2·10, 95% CI 1·43-3·06). A higher risk of hospitalisation for AT was observed with older age, male sex, a history of cardiovascular disease, splenectomy (HR 1·50, 95% CI 1·12-2·03), exposure to IVIg (HR 1·85, 95% CI 1·36-2·52) and TPO-RAs (HR 1·64, 95% CI 1·26-2·13). Rituximab was not associated with an increased risk. These findings help to estimate the risk of thrombosis in adult patients with ITP and to select treatment.

AIMS: Analgesics are the most widely used medicines worldwide. In parallel, opioid abuse has increased and is of major concern. The accessibility of pharmacologically powerful medicines and the addictovigilance signals in France about the risk of opiates addiction call for an overview of analgesic use. The objective of this study was to investigate the use of analgesics reimbursed in France over a 10-year period through its prevalence. METHODS: A cross-sectional study repeated yearly was conducted by using data from the French reimbursement database from 2006 to 2015. Analgesics were classified according to their pharmacological potency: prevalence of use for each category and sociodemographic characteristics of patients treated were analysed. RESULTS: The annual prevalence of analgesic use was high and increased during the study period (59.8%, 253 976 users in 2015). In 2015, prevalence was always higher in women and increased with age, except for those older than 84 years. Peripheral analgesics were the most used (55.3%, 234 739 users). The prevalence of weak analgesic use decreased (21.3%, 90 257 users), mainly due to the definitive withdrawal of dextropropoxyphene in France in 2011, which was not offset by an increase in the consumption of other weak analgesics. For strong analgesics (1.2%, 5129 users), morphine was the most widely used, with a dramatic increase in oxycodone use, especially in the elderly. CONCLUSION: The prevalence of analgesic use is high: approximately 31 million adults had at least 1 analgesic reimbursed in 2015. The most widely used analgesics were peripheral analgesics, far ahead of opioid analgesics.

OBJECTIVES: Previous studies in the working environment have underlined the high prevalence of drug consumption. The aim of this study was to present the main characteristics of this consumption in French workers and to identify changes from the 1986, 1996, 2006 and 2016 surveys. METHODS: The design was a repeated cross-sectional study in 1986, 1996, 2006 and 2016. At each wave, demographic and socio-professional characteristics, self-reported consumption of medications during the week before the occupational medical visit, and perceived difficult working conditions and extraprofessional problems were collected among a sample of workers. Factors associated with consumption of any drug and of main therapeutic classes were investigated through multivariate logistic regression models, using 2016 as the reference for investigating temporal trends. RESULTS: Prevalence of use of any drug was significantly higher in 2016, with marked changes observed in comparison with 1986: absolute decrease of psychotropic (-5.1%, p < 0.0001), antibiotics (-2.7%, p < 0.0001) and cardiovascular drug use (-3.8%, p < 0.0001), increase of analgesic use (+8.3%, p < 0.0001). Difficult working conditions, age and female gender were independently associated with analgesic drug use, and extraprofessional problems and female gender associated with psychotropic drug use. CONCLUSIONS: This analysis of self-reported drug use in the working environment illustrates the global patterns of medication use in a French active population over 3 decades. The favorable development in the level of consumption of psychotropic drugs should not underestimate the attention to be paid to the determinants of chronic consumption, or possible transfers to less stigmatized medications.

BACKGROUND: Use of gabapentinoids is increasing. Following recent case reports, we investigated a putative risk of parkinsonism with pregabalin or gabapentin. METHODS: A disproportionality analysis of 5,653,547 individual case safety reports in the World Health Organization individual case safety report database, VigiBase, compared all patients with parkinsonism who were receiving gabapentinoids with other patients. Results are shown as reporting odds ratios and the information component, an indicator of disproportionate Bayesian reporting. Sensitivity analyses included comparisons with drugs used for similar indications (amitriptyline, duloxetine) and exclusion of drugs that induce parkinsonism. RESULTS: Among 5,653,547 reports, 4925 parkinsonism reports were found with pregabalin and 4881 with gabapentin. Gabapentin and pregabalin were associated with increased reporting odds ratio (2.16 [2.10-2.23], 2.43 [2.36-2.50]). Similar trends were found using information components after excluding drugs that induce parkinsonism and for pregabalin compared with amitriptyline or duloxetine. CONCLUSIONS: This study found that gabapentinoids (particularly pregabalin) can be associated with parkinsonism. © 2019 International Parkinson and Movement Disorder Society.

PURPOSE: Despite their frequent use in children and adolescents, the evidence for efficacy and safety of antidepressants (ATDs) in this population is scarce and off-label prescribing common. The aim of this study was to describe reported adverse drug reactions (ADRs) associated to ATDs over a 30-year period using the French Pharmacovigilance Database (FPVD). METHODS: We performed an analysis of ADRs registered in the FPVD from 1985 to 2016, occurred in children and adolescents receiving an ATD. Descriptive statistics were used to obtain an overview of ADRs types and characteristics, and data were stratified by age. RESULTS: Among the 45,070 pediatric cases reports registered into the FPVD, we identified 1366 reports (3.0%) in which ATDs were "suspected" as the cause of 2922 ADRs. ADRs were more frequently reported in female (n = 743; 55.5%) and adolescents (n = 627; 49.3%). Neuropsychiatric ADRs were the most reported, mainly sleepiness, agitation, and suicidal thinking and behavior, followed by gastrointestinal and hepatobiliary disorders, mainly vomiting, abdominal pain, hepatitis, nausea, and three unexpected ADRs of pancreatitis. There was an increase of annual reporting between 1986 and 2003, followed by a plateau state then a decrease from 2003 to 2012, and a rapid escalation until 2016, while an increase in the number of reporting of suicidal thinking and behavior was observed after 2003, highlighting a possible impact of black box warnings on reporting practices and ATD use. CONCLUSION: This pediatric pharmacovigilance study underscored the high prevalence of neuropsychiatric and gastrointestinal ADRs, including three unexpected cases of pancreatitis.

PURPOSE: Drug-drug interactions (DDIs) require monitoring in an aging population with increasing polypharmacy exposure. We aimed to estimate the prevalence of exposure to potential DDIs using the French healthcare insurance system database, for six DDIs with various clinical relevance: angiotensin II receptor blockers or angiotensin-converting enzyme inhibitors and nonsteroidal anti-inflammatory drugs (ARBs-ACEIs + NSAIDs), antiplatelet agents and NSAIDs (AAP + NSAIDs), serotonergic drugs and tramadol (SD + T), statins and macrolides (S + M), oral anticoagulant and NSAIDs (OAC + NSAIDs), and colchicine and macrolides (C + M). METHODS: We used exhaustive healthcare data from a 1/97th random sample of the population covered by the French health insurance system (EGB) between 2006 and 2016. Exposure to a DDI was defined as overlapping exposure to two interacting drugs. The prevalence of exposure was estimated by year. RESULTS: Prevalence of exposure in 2016 was estimated at 3.7% for ARBs-ACEIs + NSAIDs, 1.5% for AAP + NSAIDs, 0.76% for SD + T, 0.36% for S + M, 0.24% for AOC + NSAIDs, and 0.02% for C + M. In 26% to 58% of episodes of exposure, the two interacting drugs were prescribed by the same physician and dispensed by the same pharmacy the same day. Between 2006 and 2016, the yearly prevalence was increasing for SD + T and for DDIs involving NSAIDs, and it was decreasing for those involving macrolides. CONCLUSION: Exposures to potential DDIs in France are not uncommon with a high proportion resulting from a co-prescription by the same physician. Monitoring the prevalence of exposure to DDIs is needed to implement prevention measures. Administrative data enable this surveillance in large and representative cohorts.
