ABSTRACT
BACKGROUND: Donepezil, rivastigmine and galantamine are popular cholinesterase inhibitors used to manage the symptoms of Alzheimer disease and other dementias; regulatory agencies in several countries warn about a possible risk of rhabdomyolysis with donepezil, based on information from case reports. Our goal was to investigate the 30-day risk of admission to hospital with rhabdomyolysis associated with initiating donepezil versus other cholinesterase inhibitors. METHODS: We conducted a retrospective cohort study in Ontario, Canada, from 2002 to 2017. Participants were adults aged 66 years or older with a newly dispensed prescription for donepezil compared with rivastigmine or galantamine. The primary outcome was hospital admission with rhabdomyolysis (assessed using hospital diagnostic codes) within 30 days of a new prescription of a cholinesterase inhibitor. Odds ratios were estimated using logistic regression, with inverse probability of treatment weights calculated from propensity scores. RESULTS: The average age in our 2 groups was 81.1 years, and 61.4% of our population was female. Donepezil was associated with a higher risk of hospital admission with rhabdomyolysis compared with rivastigmine or galantamine (88 events in 152 300 patients [0.06%] v. 16 events in 68 053 patients [0.02%]; weighted odds ratio of 2.21, 95% confidence interval [CI] 1.52-3.22). Most hospital admissions with rhabdomyolysis after donepezil use were not severe, and no patient was treated with acute dialysis or mechanical ventilation. INTERPRETATION: Initiating donepezil is associated with a higher 30-day risk of admission to hospital with rhabdomyolysis compared with initiating rivastigmine or galantamine. The proportion of patients who develop severe rhabdomyolysis within 30 days of initiating donepezil is very low.

Hemodialysis is a life-sustaining treatment for persons with kidney failure. However, those on hemodialysis still face a poor quality of life and a short life expectancy. High-quality research evidence from large randomized controlled trials is needed to identify interventions that improve the experiences, outcomes, and health care of persons receiving hemodialysis. With the support of the Canadian Institutes of Health Research and its Strategy for Patient-Oriented Research, the Innovative Clinical Trials in Hemodialysis Centers initiative brought together Canadian and international kidney researchers, patients, health care providers, and health administrators to participate in a workshop held in Toronto, Canada, on June 2 and 3, 2018. The workshop served to increase knowledge and awareness about the conduct of innovative, pragmatic, cluster-randomized registry trials embedded into routine hemodialysis care and provided an opportunity to discuss and build support for new trial ideas. The workshop content included structured presentations, facilitated group discussions, and expert panel feedback. Partnerships and promising trial ideas borne out of the workshop will continue to be developed to support the implementation of future large-scale trials.
L'hémodialyse constitue un traitement essentiel au maintien de la vie pour les personnes atteintes d'insuffisance rénale. Les patients hémodialysés voient cependant leur qualité et leur espérance de vie réduites. Des données de recherches probantes, provenant de vastes essais cliniques contrôlés à répartition aléatoire, sont nécessaires pour améliorer l'expérience, les résultats et les soins des patients hémodialysés. Grâce au soutien des Instituts de recherche en santé du Canada (IRSC) et de leur Stratégie de recherche axée sur le patient (SRAP), l'initiative sur les essais cliniques novateurs (ECN) en centres d'hémodialyse a réuni divers intervenants en santé rénale (chercheurs, patients, fournisseurs de soins et administrateurs), du Canada et de partout dans le monde, lors d'un colloque qui s'est tenu à Toronto les 2 et 3 juin 2018. Ce colloque a permis d'accroître la sensibilisation et les connaissances sur la conduite d'essais cliniques novateurs, répartis en grappes, pragmatiques et intégrés aux soins d'hémodialyse de routine. Cette rencontre a également fourni une occasion de discuter de nouvelles idées d'essais cliniques et de susciter les appuis nécessaires à leur réalisation. Le colloque s'est déroulé sous forme de présentations structurées, de discussions animées en groupe et de rétroaction de la part d'un comité d'experts. Les idées de recherche prometteuses et les partenariats issus de ce colloque continueront d'être développés pour soutenir la réalisation d'essais cliniques futurs de grande envergure.
