Pharmacogenetics of opiates in clinical practice: the visible tip of the iceberg

Opioids are the cornerstone of analgesic therapy and are used as a substitution therapy for opiate addiction. Interindividual variability in response to opioids is a significant challenge in the management of pain and substitution. Therefore, treatment with opioids requires a careful individualization of dosage to achieve an appropriate balance of efficacy and adverse effects and, consequently, avoid toxicity, particularly respiratory depression, sedation and for some, cardiac ventricular fibrillations. Many studies have investigated the association between genetic factors and the variability of response to opioids. Variants in genes encoding proteins implied in opioid pharmacokinetics (absorption, distribution, metabolism, excretion and toxicity), together with those implied in opioids direct and indirect pharmacodynamics (genes of opioid receptors and monoaminergic systems), are the most studied. Many association studies have not been replicated. The purpose of this article is to summarize pharmacogenetic data associated with some opioids frequently encountered in managed care settings.

Internet Addiction and Relationships with Insomnia, Anxiety, Depression, Stress and Self-Esteem in University Students: A Cross-Sectional Designed Study

Background and Aims Internet addiction (IA) could be a major concern in university medical students aiming to develop into health professionals. The implications of this addiction as well as its association with sleep, mood disorders and self-esteem can hinder their studies, impact their long-term career goals and have wide and detrimental consequences for society as a whole. The objectives of this study were to: 1) Assess potential IA in university medical students, as well as factors associated with it; 2) Assess the relationships between potential IA, insomnia, depression, anxiety, stress and self-esteem. Methods Our study was a cross-sectional questionnaire-based survey conducted among 600 students of three faculties: medicine, dentistry and pharmacy at Saint-Joseph University. Four validated and reliable questionnaires were used: the Young Internet Addiction Test, the Insomnia Severity Index, the Depression Anxiety Stress Scales (DASS 21), and the Rosenberg Self Esteem Scale (RSES). Results The average YIAT score was 30 ± 18.474; Potential IA prevalence rate was 16.8% (95% confidence interval: 13.81–19.79%) and it was significantly different between males and females (p-value = 0.003), with a higher prevalence in males (23.6% versus 13.9%). Significant correlations were found between potential IA and insomnia, stress, anxiety, depression and self-esteem (p-value < 0.001); ISI and DASS sub-scores were higher and self-esteem lower in students with potential IA. Conclusions Identifying students with potential IA is important because this addiction often coexists with other psychological problems. Therefore, interventions should include not only IA management but also associated psychosocial stressors such as insomnia, anxiety, depression, stress, and self-esteem.

Insomnia and Relationship with Anxiety in University Students: A Cross-Sectional Designed Study.

Purpose Sleep disorders (SDs) are now recognized as a public health concern with considerable psychiatric and societal consequences specifically on the academic life of students. The aims of this study were to assess SDs in a group of university students in Lebanon and to examine the relationship between SDs and anxiety. Methods An observational cross-sectional study was conducted at Saint-Joseph University, Lebanon, during the academic year 2013–2014. Four questionnaires were face-to-face administered to 462 students after obtaining their written consent: Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Generalized Anxiety Disorder 7-item scale (GAD-7). Results The prevalence of clinically significant insomnia was 10.6% (95% CI: 7.8–13.4%), more frequent in first year students. ISI mean score was 10.06 (SD = 3.76). 37.1% of the participants were poor sleepers. Excessive daytime sleepiness (EDS) and poor sleep were significantly more frequent among participants with clinical insomnia (p = 0.031 and 0.001 respectively). Clinically significant anxiety was more frequent in students suffering from clinical insomnia (p = 0.006) and in poor sleepers (p = 0.003). 50.8% of the participants with clinically significant anxiety presented EDS versus 30.9% of those with no clinically significant anxiety (p<0.0001). Conclusions The magnitude of SDs in this sample of Lebanese university students demonstrate the importance of examining sleep health in this population. Moreover, the link between SD and anxiety reminds us of the importance of treating anxiety as soon as detected and not simply targeting the reduction of sleep problems.

Comparative Assessment of Off-label and Unlicensed Drug Prescriptions in Children: FDA Versus ANSM Guidelines.

PURPOSE The main objectives of this study were to assess the incidence of off-label (OL) and/or unlicensed (UL) prescriptions in a sample of pediatric Lebanese patients by using US Food and Drug Administration (FDA) and the French Medical Regulatory Authority (ANSM) regulations. The goal was to analyze the divergences between regulations and to identify those drugs most commonly involved in OL-UL utilization. METHODS This study was a retrospective analysis (500 pediatric files) conducted in a Lebanese University hospital in 3 pediatric wards (chronic diseases, acute diseases, and the pediatric intensive care unit). FINDINGS The frequency of OL-UL drug use was significantly different between pediatric wards (P < 0.001), with the highest incidence occurring in the intensive care unit. The most frequent OL-UL prescriptions occurred with cancer (oncology) admissions. Age was significantly related to OL-UL frequency (highest incidence in children aged between 0 and 1 year). The number of drugs prescribed per patient ranged between 1 and 20 (mean [SD], 4.13 [2.6]). The incidence of OL-UL prescriptions was significantly higher in patients treated with a greater number of medicines (P < 0.001). Overall, 58.9% of drug prescriptions were authorized according to ANSM and 50.7% according to FDA regulations; 11.1% (ANSM) and 15.8% (FDA) were UL, and 30.2% (ANSM) and 33.5% (FDA), respectively, were OL use (where OL for the indication were the most common). The highest percentage of OL-UL prescriptions was seen with the following groups: blood and blood-forming organs, genitourinary system, and sex hormones. Divergence between FDA and ANSM was mainly observed for OL medicines. UL prescriptions assessed according to both regulations showed similar results. IMPLICATIONS This study highlights the need for prescribers to continuously examine updates to official regulations to avoid using an OL-UL drug whenever possible. It also calls for better harmonization between worldwide official guidelines concerning drugs used in children to reduce risk factors for adverse drug reactions.

Evaluating the impact of spirituality on the quality of life, anxiety, and depression among patients with cancer: an observational transversal study

ObjectiveSpiritual well-being was found to have some protective effect against end-of life despair in cancer patients. We aimed at assessing the impact of spirituality on the quality of life, depression, and anxiety of Lebanese cancer patients.MethodsOur observational transversal monocentric study was conducted between January and April 2016 among a convenient sample of 115 Lebanese cancer patients admitted to Hôtel-Dieu de France Hospital (HDF), Beirut—Lebanon. In addition to socio-demographic and clinical data, three questionnaires were used: EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, 3rd version), FACIT-Sp-12 (Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being; The 12-item Spiritual Well-Being Scale, 4th version), and HADS (Hospital Anxiety and Depression Scale). Eighteen patients taking anxiolytic and/or antidepressants were not included in the analysis. The remaining 97 patients were analyzed.ResultsBetter emotional and cognitive functioning was seen in patients with higher meaning, peace, faith, and total FACIT scores. Meaning, peace, and total FACIT scores were also higher among patients with better global health status and quality of life. Anxiety as well as depression was significantly associated to all spiritual well-being factors.ConclusionSpirituality can improve quality of life and decrease the incidence of anxiety and depression in cancer patients. Our results highlight the need to incorporate spiritual care in healthcare systems.

Associations between quality of life, physical activity, worry, depression and insomnia: A cross-sectional designed study in healthy pregnant women

Health-related quality of life (QOL) is reported to be reduced during pregnancy. Associations between QOL, physical activity (PA), insomnia, depression and worry are insufficiently investigated among pregnant women. The aim of this study was to evaluate QOL and PA patterns among healthy pregnant women, and to examine how QOL might correlate to PA, sleep, worry and depression. This is an observational cross-sectional study, conducted among a convenient sample of 141 healthy pregnant women using five questionnaires: WHOQOL-brief (WHO quality of life questionnaire, brief version, ISI (Insomnia Severity Index), PSWQ (Penn State Worry Questionnaire), ZSRDS (Zung Self-Rating Depression Scale), and Pregnancy Physical Activity Questionnaire (PPAQ). Pre-gestational BMI was inversely correlated to overall health while education was positively correlated to psychological health, social relationships and environment domains. Smoking before and during pregnancy significantly impacted the general health and psychological health. Total and light PA were positively correlated to psychological health and social relationships. Sports/exercise showed positive correlations with several QOL domains. Insomnia and depression were significantly associated with a decrease in all domains of QOL, while worries were associated with a decrease in physical, psychological and environmental domains. There were significant negative correlations between ZSRDS scores and total activity. PA, worries, depression and insomnia affected QOL during pregnancy. Furthermore, pregnant women presenting depression had a reduced total PA. Sleep and mental health as well as encouraging PA during pregnancy are necessary to improve the quality of life of pregnant women.

Validation of the Arabic Version of the Migraine Disability Assessment Scale Among Lebanese Patients with Migraine

AIMS To validate the Arabic version of the Migraine Disability Assessment Scale (MIDAS) and to evaluate the impact of the most frequently studied risk factors for migraine disability on the total MIDAS score in a Lebanese population. METHODS This prospective study was performed from January 2017 to May 2017 and included 44 patients with migraine. Data were obtained using a questionnaire identifying sociodemographic characteristics, medical history, and migraine characteristics. The Arabic MIDAS was used to quantify the disability associated with headaches over a 3-month period. Ten days after completing the MIDAS, the participants were interviewed again to assess test-retest reproducibility. The validity of the MIDAS construct in the Lebanese population was confirmed by carrying out factor analyses for all the items of the questionnaire using the principal component analysis technique with a promax rotation. RESULTS The MIDAS items converged over a solution of one factor that had an eigenvalue > 1, explaining a total of 63.25% of the variance (Cronbachs alpha = 0.812). Photophobia, vomiting, and duration of migraine attack of 24 to 48 hours significantly increased the MIDAS score by 21.396, 22.0, and 17.396 points, respectively, whereas a high socioeconomic level significantly decreased the MIDAS score by 6.837 points. CONCLUSION This first linguistically validated Arabic version of the MIDAS was developed to improve migraine management in Arabic-speaking patients. Moreover, the results suggest that having longer migraine duration, more accompanying symptoms, and a low socioeconomic level can increase the MIDAS score and thus the level of disability.

Adherence to oral glucose lowering drugs, quality of life, treatment satisfaction and illness perception: A cross-sectional study in patients with type 2 diabetes

Objective To evaluate treatment adherence to oral glucose lowering drugs (OGLD) and health related quality of life in Lebanese diabetics. Secondary objectives were to examine associations between treatment adherence, quality of life (QOL), treatment satisfaction and illness perception. Methods This cross-sectional study, conducted in all districts of Lebanon between August 2016 and April 2017, enrolled 207 adult patients, taking any OGLD. Results The effectiveness score (Beta = 0.55), female gender (Beta = 7.04), and the quality of life score (Beta = 0.28) would significantly increase the adherence score respectively. On another hand, the body mass index (Beta = −1.216) would significantly decrease the adherence score. Adherence was negatively and significantly associated to IPQ score (r = −0.181), effectiveness score (r = −0.504), side effects (r = −0.583), convenience (r = −0.317), global satisfaction (r = −0.428), physical health (r = −0.477), psychological health (r = −0.521), social relationships (r = −0.405) and environment (r = −0.429). Conclusion Perceived effectiveness and patient’s quality of life seem to be important parameters enhancing adherence. Based on this study, planning interventions to enhance treatment adherence and improve the quality of life is crucial for all diabetic patients. Additional efforts are suggested to be made by concerned authorities to set up awareness campaigns to increase alertness on the importance of adherence to medications in diabetics.

Association Between Adherence to Statins, Illness Perception, Treatment Satisfaction, and Quality of Life among Lebanese patients

Objectives: The main objective of this study was to evaluate treatment adherence to statin and health-related quality of life (QOL) in Lebanese patients with dyslipidemia. Secondary objectives were to examine associations between treatment adherence, QOL, treatment satisfaction, and illness perception. Methods: This cross-sectional study, conducted in 20 community pharmacies from all districts of Lebanon between August 2016 and April 2017, enrolled 247 adult patients taking any statin. Results: The mean age of the participants was 52.63 ± 11.92 years (57.5% males); the mean duration of treatment with a statin was 59.72 months. A significant association was found between adherence and marital status (P < .0001), educational level (P = .001), cigarette smoking (P < .0001), and alcohol drinking (P < .0001). A negative but significant correlation was found between the adherence score and the duration of dyslipidemia (r = −0.199). A significant but negative correlation was also found between the side effect score and age (r = −0.137). The monthly salary, the marital status, the educational level, smoking cigarettes or waterpipes, and drinking alcohol were all associated with the Illness Perception Questionnaire scores (P < 0.0001 for all variables). Secondary level of education (β = 13.43), smoking more than 3 waterpipes per week (β = 14.06), global satisfaction score (β = 0.32), convenience score (β = 0.29), and effectiveness score (β = 0.27) would significantly increase the adherence score. Smoking more than 15 cigarettes per day (β = −11.15) and a divorced status (β = −14.81) would however significantly decrease the adherence score. Significant associations were found between the illness perception score, the QOL domains, and the satisfaction domains (P < .05 for all variables). Conclusion: This study showed that global satisfaction with treatment, convenience, and effectiveness are important factors that increase treatment adherence. Patient adherence results in patient satisfaction and improved QOL and is an important criterion for achieving desired therapeutic outcomes.

Quality of Life and Its Association With Treatment Satisfaction, Adherence to Medication, and Trust in Physician Among Patients With Hypertension: A Cross-Sectional Designed Study

Objective: Patients with hypertension tend to have a lower health-related quality of life (HRQOL) compared to normotensive patients. This study’s main objectives are to assess (1) HRQOL and factors that might impact it and (2) association between HRQOL and adherence to treatment, trust in physician, and treatment satisfaction among patients with hypertension. Methods: A cross-sectional study enrolled 196 patients from medical-care offices in Beirut, North and South Lebanon. Eligible patients signed a consent form and were asked to complete the Trust in Physician Scale, World Health Organization Quality of Life-brief (WHOQOL-brief) questionnaire, and Treatment Satisfaction Questionnaire (TSQM 1.4) as well as questions assessing medication adherence. Results: Better antihypertensive medication adherence was significantly and positively correlated with better HRQOL domains except general health where significance was not reached (P = .089). Better adherence was also significantly related to better treatment satisfaction (side effects, convenience, and global satisfaction but not to effectiveness) and an increased trust in physicians (P < .0001). Better treatment satisfaction (TSQM domains) was significantly and positively associated with a better overall HRQOL (P ≤ .001). Increased trust in physician scores were significantly and positively correlated with a better psychological health, environment, and overall HRQOL domains (P = .045, .005, and .006, respectively). Finally, TSQM effectiveness, convenience, and global satisfaction were significantly higher when trust in physician was greater (P = .017, .035, and .002, respectively). Conclusion: The results of this study revealed an association between increased adherence to treatment, a higher global satisfaction, and an increased quality of life. An increased patient satisfaction with their antihypertensive treatment and trust in their physician were also correlated with a greater adherence to treatment.
