RESUMEN

PURPOSE: Sensory chemotherapy-induced peripheral neuropathy (CIPN) is well-recognized, but motor CIPN remains understudied. This secondary analysis focused on the long-term severity and impact of motor disorders, their relation to sensory CIPN, neuropathic pain, psychological distress, and health-related quality of life (HRQoL) after oxaliplatin-based chemotherapy in colorectal cancer (CRC) survivors. METHODS: Data from a multicenter, cross-sectional study were re-analyzed to explore motor CIPN among CRC survivors up to 5 years post-chemotherapy, with no longitudinal follow-up. Questionnaires assessed sensory and motor CIPN (QLQ-CIPN20), neuropathic pain (DN4), anxiety and depression (HADS), and HRQoL (QLQ-C30). RESULTS: Among 405 CRC survivors, 31.1% had sensory CIPN as previously described. When categorizing the 405 CRC survivors based on the years since their last oxaliplatin-based chemotherapy, the motor scores derived from the QLQ-CIPN20 showed no significant difference between years (p = 0.08). Motor CIPN scores correlated with female gender, higher oxaliplatin dose intensity, sensory CIPN, and neuropathic pain. Motor CIPN also linked to decreased HRQoL and increased psychological distress. CONCLUSION: The study underscores the detrimental impact of motor disorders on CRC survivors post-oxaliplatin-based chemotherapy. Oncologists should prioritize assessing and managing motor manifestations alongside sensory symptoms to enhance post-cancer quality of life.

RESUMEN

OBJECTIVE: Alzheimer's disease or Related Dementia (ADRD) is known to disturb pain perception and reduce the ability to report it, resulting in underestimation by practitioners and sub-optimal medical management. The aim of this study was to estimate the prevalence of all types of CP among people with ADRD. DESIGN: Nationwide cross-sectional study. SETTINGS: French community-dwelling and nursing home residents. PARTICIPANTS: People with ADRD, >40 years old, treated with cholinesterase inhibitors or memantine, or with a diagnosis/long-term illness of ADRD and matched with a comparison sample. SETTINGS: French community-dwelling and nursing home residents. PARTICIPANTS: People with ADRD, >40 years old, treated with cognitive stimulants (cholinesterase inhibitors and memantine) or with a diagnosis/long-term illness of ADRD and matched with a comparison sample (non-ADRD). MEASUREMENTS: The capture-recapture method was performed to provide estimates of the prevalence of CP. People treated with analgesic drugs for ≥6 months consecutively or with a medical diagnosis of CP (ICD-10 codes) or referred to a pain center were considered as having CP. RESULTS: A total of 48,288 individuals were included, of which 16,096 had ADRD and 32,192 without ADRD. The estimated prevalence of CP in people with ADRD was from 57.7% [52.9;63.3] to 57.9%[53.0;63.9], and slightly higher than the non-ADRD sample (from 49.9%[47.0;53.2] to 50.4%[47.3;53.9], p <0.001). CONCLUSIONS: The prevalence of CP among people living with ADRD was at least the same as or better than individuals without ADRD. This result should alert practitioners' attention to the need for effective pain assessment and management in this population who has difficulties to express and feel pain.

RESUMEN

BACKGROUND: The use of oxaliplatin in digestive tract cancers could induce severe peripheral neuropathy (OIPN) decreasing the quality of life of patients and survivors. There is currently, no univocal treatment for these peripheral neuropathies. Donepezil, a reversible inhibitor of cholinesterase, used to treat Alzheimer's disease and dementia, is reported to have a good safety profile in humans, and preclinical data have provided initial evidence of its effectiveness in diminishing neuropathic symptoms and related comorbidities in OIPN animal models. METHODS: The DONEPEZOX trial will be a proof-of-concept, randomised, triple-blinded, and multicentre study. It will be the first clinical trial evaluating the efficacy and safety of donepezil for the management of OIPN. Adult cancer survivors with OIPN that report sensory neuropathy according to QLQ-CIPN20 sensory score (equivalence of a grade ≥ 2), at least 6 months after the end of an oxaliplatin-based chemotherapy will be included. Eighty patients will be randomly assigned to receive either donepezil or placebo over 16 weeks of treatment. The primary endpoint will be the rate of responders (neuropathic grade decreases according to the QLQ-CIPN20 sensory score) in the donepezil arm. The severity of OIPN will be assessed by the QLQ-CIPN20 sensory scale before and after 16 weeks of treatment. The comparison versus the placebo arm will be a secondary objective. The other secondary endpoints will be tolerance to donepezil, the severity and features of OIPN in each arm before and after treatment, related-comorbidities and quality of life. Fleming's one-stage design will be used for sample size estimation. This design yields a type I error rate of 0.0417 and power of 91% for a responder rate of at least 30% in donepezil arm. A total of 80 randomized patients is planned. DISCUSSION: This study will allow, in the case of positive results, to initiate a phase 3 randomized and placebo-controlled (primary endpoint) clinical study to assess the therapeutic interest of donepezil to treat OIPN.

RESUMEN

PURPOSE: The Prescription Opioid Misuse Index scale (POMI) is a brief questionnaire used to assess opioid prescription misuse. In view of the increase in the prescription of opioid analgesics for chronic noncancer pain (CNCP), this tool is particularly useful during medical consultations to screen opioid misuse in patients using opioids. We sought to generate and validate a French-European translation of the POMI. METHODS: We conducted an observational, longitudinal, and multicenter psychometric study with crosscultural validation. All adult CNCP patients who were treated with opioids for at least three months, were followed in pain clinics, and spoke French were eligible. From September 2015 to November 2017, we included 163 patients and analyzed 154. We performed a pretest on a sample of representative patients to evaluate acceptability and understanding of translation. Study patients completed the POMI scale at a pain clinic (test phase), and we assessed test-retest reliability after two to four weeks by a second completion of the POMI scale at home by patients (retest phase). We subsequently explored psychometric properties of the POMI (acceptability, internal consistency, reproducibility, and external validity). RESULTS: Due to poor internal consistency and reproducibility, items 4, 7, and 8 of the original POMI scale were removed, and we proposed a five-question French-European version (POMI-5F). The internal consistency of POMI-5F was good (Cronbach's α = 0.71), as was test-retest reliability (r = 0.65 [0.55-0.67]). The external validity of POMI-5F, compared with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, was moderate but significant (r = 0.45; P < 0.001). The optimal POMI-5F cut-off score to indicate misuse was 2/5 (sensitivity = 0.95 and specificity = 0.54). CONCLUSION: We generated and validated a French-European translation of the POMI scale, POMI-5F, for use by French researchers and physicians to identify opioid misuse in CNCP patients.


RéSUMé: OBJECTIF: L'échelle Prescription Opioid Misuse Index (POMI) est un questionnaire court utilisé pour évaluer le mésusage de la prescription d'opioïdes. Face à l'augmentation de la prescription d'antalgiques opioïdes pour les douleurs chroniques non cancéreuses (DCNC), cet outil est particulièrement utile lors des consultations médicales pour dépister le mésusage chez les patients utilisateurs d'opioïdes. Nous avons cherché à générer et à valider une traduction franco-européenne de la POMI. MéTHODES: Nous avons mené une étude psychométrique observationnelle, longitudinale et multicentrique avec une validation transculturelle. Tous les patients souffrant de DCNC, traités par opioïdes depuis au moins trois mois, suivis en structures douleur chronique et parlant le Français étaient éligibles. De septembre 2015 à novembre 2017, 163 patients ont été inclus et 154 analysés. Un pré-test a été réalisé sur un échantillon de patients représentatifs pour évaluer l'acceptabilité et la compréhension de la traduction. Les patients de l'étude ont rempli l'échelle POMI (phase TEST) au sein du centre investigateur et la fiabilité du test­retest a été évaluée après deux à quatre semaines par un second remplissage de l'échelle POMI à domicile par les patients (phase RETEST). Ensuite, les propriétés psychométriques de l'échelle POMI ont été explorées (acceptabilité, cohérence interne, reproductibilité et validité externe). RéSULTATS: En raison d'une faible cohérence interne et reproductibilité, les items 4, 7 et 8 de l'échelle POMI originale ont été supprimés, et nous avons proposé une version française (Europe) à cinq questions (POMI-5F). La cohérence interne de l'échelle POMI-5F était bonne (α de Cronbach = 0,71), tout comme la fiabilité test­retest (r = 0,65 [0,55­0,67]). La validité externe du POMI-5F, comparée à la cinquième édition du Manuel diagnostique et statistique des troubles mentaux (DSM-5), était modérée mais significative (r = 0,45; P < 0,001). Le score seuil optimal du POMI-5F pour indiquer un mésusage était de 2/5 (sensibilité = 0,95 et spécificité = 0,54). CONCLUSION: Nous avons généré et validé une traduction franco-européenne de l'échelle POMI, POMI-5F, pour une utilisation par les chercheurs et les médecins français afin d'identifier le mésusage des opioïdes chez les patients souffrant de DCNC.

RESUMEN

PURPOSE: Bortezomib is a neurotoxic drug used in multiple myeloma and responsible for chemotherapy-induced peripheral neuropathy (CIPN). In a previous cross-sectional study, CIPN prevalence was about 26.9% in 67 patients. A second data analysis was performed to explore the relation between CIPN and auditory difficulties. METHODS: Based on 66 multiple myeloma patients from a single center, auditory difficulties were assessed with a self-questionnaire and compared to sensory CIPN (QLQ-CIPN20 questionnaire), patients' characteristics and anticancer treatments. RESULTS: The prevalence of auditory difficulties was about 42.4% (95% CI [30.6-55.2]) of the 66 patients analyzed and was higher in patients with CIPN than without (82.4% vs. 28.6%, p < 0.001). Auditory difficulties were not related to the characteristics of patients and treatments. The severity of auditory difficulties were correlated to CIPN severity (spearman's coefficient: 0.49, p = 0.009). Odds-ratio of auditory difficulties (multivariable analysis adjusted for sensory CIPN, recreation or professional noise exposure, gender, age, and treatments) was significantly associated with CIPN (18.7, 95% CI [3.0-117.1], p = 0.002). CONCLUSION: This relation between CIPN and auditory difficulties raises concerns about hearing safety in multiple myeloma patients treated by bortezomib. TRIAL REGISTRATION NUMBER: NCT03344328.

RESUMEN

PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) is challenging for oncologists. Many publications mention the high incidence of CIPN and the lack of effective preventive/management strategies and robust diagnostic tools. This cross-sectional study was aimed at assessing the practice of French oncologists for CIPN prevention, diagnosis and management. METHODS: This web-based survey was sent to French oncologists by the regional cancer networks. Incidence and impact of CIPN were assessed using visual analogue scales (VAS) and diagnostic strategies were recorded. Also recorded were the drugs used to prevent or manage CIPN and their perceived efficacy and safety (VAS). RESULTS: Among the 210 oncologists included, the perceived incidence of CIPN was about 36.2 ± 22.1% of patients. About 99.5% of oncologists declared that they assess CIPN during medical follow-up. The use of drugs to prevent CIPN was reported by 9.6% of oncologists (group B vitamins (35.0%) and calcium and magnesium infusion (25.0%)). In the case of CIPN, the therapeutic adjustment of neurotoxic anticancer drugs is performed by 99.0% of oncologists (chemotherapy change (49.8%), dose reduction (30.9%) or interruption (19.3%)). The pharmacological management of CIPN was declared by 72.9% of oncologists. The main drugs used are pregabalin (75.8%), amitriptyline (32.7%) and gabapentin (25.5%). Duloxetine (ASCO recommendation) is used by only 11.8% of oncologists. CONCLUSION: Oncologists were clearly aware of CIPN risks, but its incidence tended to be underestimated and the ASCO recommendations for the management of CIPN were not followed. The prevention, diagnosis and management of CIPN remain problematic in clinical practice in France. TRIAL REGISTRATION: ClinicalTrials.gov : NCT03854864.

RESUMEN

BACKGROUND: Chronic pain affects approximately 30% of the general population, severely degrades quality of life and professional life, and leads to additional health care costs. Moreover, the medical follow-up of patients with chronic pain remains complex and provides only fragmentary data on painful daily experiences. This situation makes the management of patients with chronic pain less than optimal and may partly explain the lack of effectiveness of current therapies. Real-life monitoring of subjective and objective markers of chronic pain using mobile health (mHealth) programs could better characterize patients, chronic pain, pain medications, and daily impact to help medical management. OBJECTIVE: This cohort study aimed to assess the ability of our mHealth tool (eDOL) to collect extensive real-life medical data from chronic pain patients after 1 year of use. The data collected in this way would provide new epidemiological and pathophysiological data on chronic pain. METHODS: A French national cohort of patients with chronic pain treated at 18 pain clinics has been established and followed up using mHealth tools. This cohort makes it possible to collect the determinants and repercussions of chronic pain and their evolutions in a real-life context, taking into account all environmental events likely to influence chronic pain. The patients were asked to complete several questionnaires, body schemes, and weekly meters, and were able to interact with a chatbot and use educational modules on chronic pain. Physicians could monitor their patients' progress in real time via an online platform. RESULTS: The cohort study included 1427 patients and analyzed 1178 patients. The eDOL tool was able to collect various sociodemographic data; specific data for characterizing pain disorders, including body scheme; data on comorbidities related to chronic pain and its psychological and overall impact on patients' quality of life; data on drug and nondrug therapeutics and their benefit-to-risk ratio; and medical or treatment history. Among the patients completing weekly meters, 49.4% (497/1007) continued to complete them after 3 months of follow-up, and the proportion stabilized at 39.3% (108/275) after 12 months of follow-up. Overall, despite a fairly high attrition rate over the follow-up period, the eDOL tool collected extensive data. This amount of data will increase over time and provide a significant volume of health data of interest for future research involving the epidemiology, care pathways, trajectories, medical management, sociodemographic characteristics, and other aspects of patients with chronic pain. CONCLUSIONS: This work demonstrates that the mHealth tool eDOL is able to generate a considerable volume of data concerning the determinants and repercussions of chronic pain and their evolutions in a real-life context. The eDOL tool can incorporate numerous parameters to ensure the detailed characterization of patients with chronic pain for future research and pain management.

RESUMEN

To assess studies examining the prevalence of chronic pain (CP) in patients treated with Opioid Substitution Treatment (OST - buprenorphine or methadone) for Opioid Used Disorder (OUD), we conducted a systematic review and meta-analysis of the literature between the years 2000 and 2020. We searched EMBASE, PsycINFO, Cochrane, and MEDLINE databases and included studies assessing the prevalence of CP in OUD adults treated with OST. The studies were assessed for risk of bias and overall quality and the results were pooled using a random-effects model. Subgroup analyses and meta-regressions were used to identify possible factors associated with CP. Twenty-three studies reported data on the prevalence of CP in patients treated with OST were evaluated. The prevalence obtained was 45.3% (CI95% [38.7; 52.1]). Overall, 78.3% of the studies had a low risk of bias. Subgroup analysis estimates did not vary according to gender, OST, and CP duration. However, it appeared that the clinical settings was associated with a lower CP prevalence when assessed in primary care sites. Our study provided an estimate regarding the prevalence of CP among OST patients. These patients deserve specific attention from health professionals and health authorities. Thus, the real challenge in OST patients is the implementation of a multidisciplinary approach to manage CP. PERSPECTIVE: Our meta-analysis provided an estimate of CP prevalence, reaching almost 50% of OUD patients with OST. Thus, the urgent challenge in OST patients is to pay systematic attention to chronic pain diagnosis, along with the implementation of a multidisciplinary patient-focused approach for an appropriate management of CP.

RESUMEN

Introduction: Chronic pain (CP) is one of the most disabling conditions in the elderly and seems to be a risk factor for the development of Alzheimer's disease and related dementias (ADRD). Only one study, using national administrative health databases, assessed and demonstrated that chronic pain (all types of pain) was a risk factor for dementia, but without assessing the impact of pain medications. Method: To assess the impact of all types of chronic pain and the long-term use of pain medications on the person-years incidence of ADRD, a retrospective nationwide healthcare administrative data study was performed using the national inter-regime health insurance information system (SNIIRAM) to the French national health data system (SNDS). Incident people >50 years old with chronic pain, defined by at least 6-months duration analgesics treatment or by a diagnosis/long-term illness of chronic pain between 2006 and 2010, were included. Chronic pain individuals were matched with non-CP individuals by a propensity score. Individuals were followed up from 9 to 13 years to identify occurrences of ADRD from 2006. Results: Among 64,496 French individuals, the incidence of ADRD was higher in the chronic pain population than control (1.13% vs. 0.95%, p <0.001). Chronic pain increases the risk of ADRD (HR = 1.23) and the incidence of ADRD was higher for women and increased significantly with age. Discussion: Our study highlights the importance of prevention, diagnosis, and management of chronic pain in elderly to reduce the risk of development and/or worsening of dementia.

RESUMEN

BACKGROUND AND PURPOSE: T-type calcium channels, mainly the Cav 3.2 subtype, are important contributors to the nociceptive signalling pathway. We investigated their involvement in inflammation and related pain-like symptoms. EXPERIMENTAL APPROACH: The involvement of Cav 3.2 and T-type channels was investigated using genetic and pharmacological inhibition to assess mechanical allodynia/hyperalgesia and oedema development in two murine inflammatory pain models. The location of Cav 3.2 channels involved in pain-like symptoms was studied in mice with Cav 3.2 knocked out in C-low threshold mechanoreceptors (C-LTMR) and the use of ABT-639, a peripherally restricted T-type channel inhibitor. The anti-oedema effect of Cav 3.2 channel inhibition was investigated in chimeric mice with immune cells deleted for Cav 3.2. Lymphocytes and macrophages from either green fluorescent protein-targeted Cav 3.2 or KO mice were used to determine the expression of Cav 3.2 protein and the functional status of the cells. KEY RESULTS: Cav 3.2 channels contributed to the development of pain-like symptoms and oedema in the two murine inflammatory pain models. Our results provided evidence of the involvement of Cav 3.2 channels located on C-LTMRs and spinal cord in inflammatory pain. Cav 3.2 channels located in T cells and macrophages contribute to the inflammatory process. CONCLUSION AND IMPLICATIONS: Cav 3.2 channels play crucial roles in inflammation and related pain, implying that targeting of Cav 3.2 channels with pharmacological agents could be an attractive and readily evaluable strategy in clinical trials, to relieve chronic inflammatory pain in patients.

RESUMEN

Background: National health monitoring agencies have reported the alternative use of morphine sulfate painkiller for maintenance treatment of opioid use disorder (OUD), associated with a potential increase in overdose risk. Objectives: This study sought to assess the prevalence of regular and occasional legally prescribed morphine use in patients treated for OUD and compare their characteristics to those of patients receiving conventional opioid maintenance treatment (OMT), buprenorphine or methadone. Then, we assessed the factors associated with opioid overdose risk. Methods: Data were extracted from the French national healthcare system database, covering the entire population in 2015. Diagnosis associated with hospital discharge and long-term disease codes were extracted to select the population and identify outcomes and covariates. OUD non-chronic pain patients were divided into regular (≤35 days between dispensing and ≥3 months of continuous treatment duration) morphine users, and occasional users. Their sociodemographic and health characteristics were compared to OMT controls. A multivariate logistic regression model was performed to determine factors associated with opioid overdose. Results: In patients treated for OUD, 2,237 (2.2%) morphine users (1,288 regular and 949 occasional), 64,578 (63.7%) buprenorphine and 34,638 (34.1%) methadone controls were included. The prevalence of regular morphine use among patients treated for OUD regularly receiving an opioid was 1.3%. Compared to users who receive morphine regularly, occasional users had an increased risk of overdose [OR = 2.2 (1.5-3.3)], while the risk was reduced in the buprenorphine group [OR = 0.5 (0.4-0.7)] and not significantly different for methadone [OR = 1.0 (0.7-1.4)]. Other overdose risk factors were low-income, comorbidity, i.e., psychiatric conditions, alcohol use disorder or complications related to intravenous drug use, and coprescription with benzodiazepines or pregabalin. These factors were more frequent in morphine groups. Conclusions: Patients that were prescribed oral morphine represented a small minority of the treated for OUD. The poorer health condition affected by numerous comorbidities and higher risk of opioid overdose in patients treated with oral morphine compared with OMT controls points toward the need to better supervise the practices of these patients, to strengthen multidisciplinary care and risk reduction measures.

RESUMEN

Public health issues related to chronic pain management and the risks of opioid misuse and abuse remain a challenge for practitioners. Data on the prevalence of disorders related to the use of prescribed opioids in patients suffering from chronic pain remains rather patchy, in particular because of the absence of a gold standard for their clinical assessment. We estimated the prevalence of prescription opioid misuse (POM), using a specific and validated opioid misuse scale (POMI-5F scale), in adults with chronic non-cancer pain. Nine-hundred-fifty-one (951) patients with opioids prescription and followed-up in pain clinics and addictology centers for chronic non-cancer pain (CNCP) completed the survey interview. The results suggest that 44.4% of participants have POM, accompanied by overuse (42.5%), use of opioids for effects other than analgesia (30.9%), withdrawal syndrome (65.7%), and craving (6.9%). The motivations cited for POM, apart from pain relief, were to calm down, relax and improve mood. POM was shown to be related to male sex (OR 1.52), young age (OR 2.21) and the presence of nociplastic pain (OR 1.62) of severe intensity (OR 2.31), codeine use (OR 1.72) and co-prescription of benzodiazepines (OR 1.59). Finally, despite the presence of three subgroups of misusers, no factor was associated with the intensity of misuse, reinforcing the view that distinguishing between strong and weak opioids is not appropriate in the context of use disorder. Almost half of patients with CNCP misuse their prescribed opioid. Practitioners should be attentive of profiles of patients at risk of POM, such as young, male patients suffering from severe nociplastic pain, receiving prescription for codeine and a co-prescription for benzodiazepine. We encourage French-speaking practitioners to use the POMI-5F scale to assess the presence of POM in their patients receiving opioid-based therapy.

RESUMEN

Analgesic opioid (AO) misuse by patients ranges from 0% to 50%. General practitioners are the first prescribers of AO. Our objective was to validate the Prescription Opioid Misuse Index (POMI) in primary care. We conducted a psychometric study in patients with chronic pain who had been taking AOs for at least 3 months and were followed in general practice. Patients responded to the POMI at inclusion and after 2 weeks. The reference used was the DSM-V. Sixty-nine GPs included 160 patients (87 women, 54.4%), mean age 56.4 ± 15.2 years. The total POMI score was 1.50 ± 1.27, and 73/160 (45.6.0%) had a score ≥ 2 (misuse threshold). Internal validity was measured with the Kuder-Richardson coefficient, which was 0.44. Correlations between each item and the total score ranged from 0.06 to 0.35. Test-retest reliability was determined from 145 patients: Lin's concordance coefficient was 0.57 [0.46, 0.68]. Correlation with the DSM-V (Spearman's coefficient) was 0.52. The POMI does not have sufficient psychometric properties to be recommended as a tool to identify the misuse of AOs in primary care. This study clearly showed that there is a need to create a monitoring tool specific to primary care.

RESUMEN

BACKGROUND: Chronic pain affects approximately 30% of the general population, severely degrades quality of life (especially in older adults) and professional life (inability or reduction in the ability to work and loss of employment), and leads to billions in additional health care costs. Moreover, available painkillers are old, with limited efficacy and can cause significant adverse effects. Thus, there is a need for innovation in the management of chronic pain. Better characterization of patients could help to identify the predictors of successful treatments, and thus, guide physicians in the initial choice of treatment and in the follow-up of their patients. Nevertheless, current assessments of patients with chronic pain provide only fragmentary data on painful daily experiences. Real-life monitoring of subjective and objective markers of chronic pain using mobile health (mHealth) programs can address this issue. OBJECTIVE: We hypothesized that regular patient self-monitoring using an mHealth app would lead physicians to obtain deeper understanding and new insight into patients with chronic pain and that, for patients, regular self-monitoring using an mHealth app would play a positive therapeutic role and improve adherence to treatment. We aimed to evaluate the feasibility and acceptability of a new mHealth app called eDOL. METHODS: We conducted an observational study to assess the feasibility and acceptability of the eDOL tool. Patients completed several questionnaires using the tool over a period of 2 weeks and repeated assessments weekly over a period of 3 months. Physicians saw their patients at a follow-up visit that took place at least 3 months after the inclusion visit. A composite criterion of the acceptability and feasibility of the eDOL tool was calculated after the completion of study using satisfaction surveys from both patients and physicians. RESULTS: Data from 105 patients (of 133 who were included) were analyzed. The rate of adherence was 61.9% (65/105) after 3 months. The median acceptability score was 7 (out of 10) for both patients and physicians. There was a high rate of completion of the baseline questionnaires and assessments (mean 89.3%), and a low rate of completion of the follow-up questionnaires and assessments (63.8% (67/105) and 61.9% (65/105) respectively). We were also able to characterize subgroups of patients and determine a profile of those who adhered to eDOL. We obtained 4 clusters that differ from each other in their biopsychosocial characteristics. Cluster 4 corresponds to patients with more disabling chronic pain (daily impact and comorbidities) and vice versa for cluster 1. CONCLUSIONS: This work demonstrates that eDOL is highly feasible and acceptable for both patients with chronic pain and their physicians. It also shows that such a tool can integrate many parameters to ensure the detailed characterization of patients for future research works and pain management.

RESUMEN

Chronic pain prevention and treatment constitute a challenge for occupational health The aim of this study was to provide data on workers in a variety of jobs and multiple contexts to determine the prevalence and characteristics of different chronic pain disorders, in view to highlighting possible new targets for preventive actions. 1,008 participants working in 14 French IKEA stores were analyzed in this observational study on the basis of their responses to surveys on their sociodemographic characteristics, psychosocial factors, lifestyle, and pain disorders. The prevalence of chronic pain, moderate-to-severe chronic pain and high-impact chronic pain were 49%, 30%, and 11%, respectively. Chronic pain was predominantly located in the neck and back, and identified mostly as nociceptive, with, for some participants, a neuropathic component (mixed pain). The majority of chronic pain was reported as being due to professional activity, and causing at least one work stoppage during the past year in half of the participants. Jobs that were the most common sources of chronic pain were those with a higher proportion of repetitive gestures, no consecutive days of rest, stress at work, such as cash-register/catering jobs. Overall, this study highlighted profiles at risk of developing or suffering from chronic pain, and several associated factors: ≥40 years old, female sex, overweight/obesity, repetitive gestures, no consecutive days of rest, stress, catastrophism, workplace environment, poor quality of life, and mental state. In conclusion, these data give interesting information on the characteristics of workers with chronic pain and highlight profiles of participants. Perspective: This study provides important information about the features of chronic pain in a model of a working population of Western countries. This information can be used to propose preventive actions.

RESUMEN

INTRODUCTION: Peripheral neuropathic pain is a disabling condition for patients and a challenge for physicians. Although many drugs have been assessed in scientific studies, few have demonstrated clear clinical efficacy against neuropathic pain. Moreover, the paucity of data regarding their safety raises the question of the benefit-risk ratio when used in patients experiencing peripheral neuropathies. AREAS COVERED: We conducted a review of double-blind, placebo-controlled, randomized clinical trials to assess the safety of medications used to treat peripheral neuropathic pain. This second review was focused on opioids, cannabinoids, and other medications. The aim was to provide an overview of the treatment-emergent adverse events (TEAEs) (≥10%) and the serious adverse effects described in clinical trials. EXPERT OPINION: Opioids and cannabinoids had significantly more TEAEs than placebos. Locally administered analgesics, such as capsaicin, lidocaine, botulinum toxin A seemed to have the most acceptable safety with only local adverse effects. The results for NMDA antagonists were inconclusive since no safety report was available. Less than half of the studies included presented a good description of TEAEs that included a statistical comparison versus a placebo group. Major methodological improvements must be made to ameliorate the assessment of medication safety in future clinical trials.

RESUMEN

Bortezomib is a pivotal drug for the management of multiple myeloma. However, bortezomib is a neurotoxic anticancer drug responsible for chemotherapy-induced peripheral neuropathy (CIPN). CIPN is associated with psychological distress and a decrease of health-related quality of life (HRQoL), but little is known regarding bortezomib-related CIPN. This single center, cross-sectional study assessed the prevalence and severity of sensory/motor CIPN, neuropathic pain and ongoing pain medications, anxiety, depression, and HRQoL, in multiple myeloma patients after the end of bortezomib treatment. Paper questionnaires were sent to patients to record the scores of sensory and motor CIPNs (QLQ-CIPN20), neuropathic pain (visual analogue scale and DN4 interview), anxiety and depression (HADS), the scores of HRQoL (QLQ-C30 and QLQ-MY20) and ongoing pain medications. Oncological data were recorded using chemotherapy prescription software and patient medical records. The prevalence of sensory CIPN was 26.9% (95% CI 16.7; 39.1) among the 67 patients analyzed and for a mean time of 2.9 ± 2.8 years since the last bortezomib administration. The proportion of sensory CIPN was higher among patients treated by intravenous and subcutaneous routes than intravenous or subcutaneous routes (p = 0.003). QLQ-CIPN20 motor scores were higher for patients with a sensory CIPN than those without (p < 0.001) and were correlated with the duration of treatment and the cumulative dose of bortezomib (coefficient: 0.31 and 0.24, p = 0.01 and 0.0475, respectively), but not sensory scores. Neuropathic pain was screened in 44.4% of patients with sensory CIPN and 66.7% of them had ongoing pain medications, but none were treated with duloxetine (recommended drug). Multivariable analysis revealed that thalidomide treatment (odds-ratio: 6.7, 95% CI 1.3; 35.5, p = 0.03) and both routes of bortezomib administration (odds-ratio: 13.4, 95% CI 1.3; 139.1, p = 0.03) were associated with sensory CIPN. Sensory and motor CIPNs were associated with anxiety, depression, and deterioration of HRQoL. Sensory CIPN was identified in a quarter of patients after bortezomib treatment and associated with psychological distress that was far from being treated optimally. There is a need to improve the management of patients with CIPN, which may include better training of oncologists regarding its diagnosis and pharmacological treatment.

RESUMEN

Oxaliplatin, a pivotal drug in the management of colorectal cancer, causes chemotherapy-induced peripheral neuropathy (CIPN) in a third of cancer survivors. Based on a previous cross-sectional study assessing oxaliplatin-related sensory CIPN in colorectal cancer survivors, a secondary analysis was designed to explore the possibility that different clusters of patients may co-exist among a cohort of patients with oxaliplatin-related CIPN. Other objectives were to characterize these clusters considering CIPN severity, anxiety, depression, health-related quality of life (HRQOL), patients' characteristics and oxaliplatin treatments. Among the 96 patients analyzed, three clusters were identified (cluster 1: 52, cluster 2: 34, and cluster 3: 10 patients). Clusters were significantly different according to CIPN severity and the proportion of neuropathic pain (cluster 1: low, cluster 2: intermediate, and cluster 3: high). Anxiety, depressive disorders and HRQOL alteration were lower in cluster 1 in comparison to clusters 2 and 3, but not different between clusters 2 and 3. This study underlines that patients with CIPN are not a homogenous group, and that CIPN severity is associated with psychological distress and a decline of HRQOL. Further studies are needed to explore the relation between clusters and CIPN management.

RESUMEN

INTRODUCTION: Peripheral neuropathic pain is a highly disabling condition for patients and a challenge for neurologists and pain physicians. Although many drugs have been assessed in scientific studies, few have demonstrated a clear clinical efficacy against neuropathic pain. Moreover, the paucity of data regarding their safety raised the question on the benefit-risk ratio when used in patients experiencing peripheral neuropathies. AREAS COVERED: The authors conducted a review of double-blind, placebo-controlled, randomized clinical trials to assess the safety of medications used to treat neuropathic pain. This first review was focused on antidepressant and antiepileptic medications. The aim was to provide an overview of the treatment-emergent adverse events (≥10%) and the serious adverse effects described in clinical trials. EXPERT OPINION: Among antiepileptics and antidepressants, duloxetine appeared to have the most detailed safety for the treatment of peripheral neuropathic pain. Over all studies, the most commonly reported adverse effects were dizziness, drowsiness, nausea, and constipation. Only 20.0% of the included studies (N = 90) presented a good description of adverse effects that included a statistical comparison vers usa placebo group. Important methodological improvements must be made to improve the assessment of medication safety in future clinical trials.

RESUMEN

The scarcity and limited risk/benefit ratio of painkillers available on the market, in addition to the opioid crisis, warrant reflection on new innovation strategies. The pharmacopoeia of analgesics is based on products that are often old and derived from clinical empiricism, with limited efficacy or spectrum of action, or resulting in an unsatisfactory tolerability profile. Although they are reference analgesics for nociceptive pain, opioids are subject to the same criticism. The use of opium as an analgesic is historical. Morphine was synthesized at the beginning of the 19th century. The efficacy of opioids is limited in certain painful contexts and these drugs can induce potentially serious and fatal adverse effects. The current North American opioid crisis, with an ever-rising number of deaths by opioid overdose, is a tragic illustration of this. It is therefore legitimate to develop research into molecules likely to maintain or increase opioid efficacy while improving their tolerability. Several avenues are being explored including targeting of the mu opioid receptor (MOR) splice variants, developing biased agonists or targeting of other receptors such as heteromers with MOR. Ion channels acting as MOR effectors, are also targeted in order to offer compounds without MOR-dependent adverse effects. Another route is to develop opioid analgesics with peripheral action or limited central nervous system (CNS) access. Finally, endogenous opioids used as drugs or compounds that modify the metabolism of endogenous opioids (Dual ENKephalinase Inhibitors) are being developed. The aim of the present review is to present these various targets/strategies with reference to current indications for opioids, concerns about their widespread use, particularly in chronic non-cancer pains, and ways of limiting the risk of opioid abuse and misuse.
