Glucagon-like Peptide-1 Receptor Agonists and Suicidal Ideation: Analysis of Real-Word Data Collected in the European Pharmacovigilance Database. Pharmaceuticals (Basel) 2024; 17:147. [PMID: 38399362 PMCID: PMC10892952 DOI: 10.3390/ph17020147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 01/12/2024] [Accepted: 01/16/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND A potential risk of suicide associated with liraglutide or semaglutide treatments has recently emerged. Therefore, we decided to investigate the reporting probability of suicidal events among glucagon-like peptide-1 receptor agonists (GLP-1 RAs). METHODS A retrospective pharmacovigilance study of the European Pharmacovigilance database was conducted for the period from 1 January 2018 to 10 July 2023. Disproportionality analyses (reporting odds ratio, ROR) were performed to assess the reporting probability of suicidal events among GLP-1 RAs. RESULTS A total of 230 reports of suicidal events were identified. The most reported GLP-1 RA was liraglutide (38.3%), followed by semaglutide (36.5%) and dulaglutide (16.1%). The most reported events were suicidal ideation (65.3%) and suicide attempt (19.5%). Disproportionality analysis found a higher reporting probability of suicidal events for semaglutide than dulaglutide (ROR, 2.05; 95%CI, 1.40-3.01) and exenatide (ROR, 1.81; 95%CI, 1.08-3.05). In the same way, liraglutide was associated with a higher reporting probability of suicidal events than dulaglutide (ROR, 3.98; 95%CI, 2.73-5.82) and exenatide (ROR, 3.52; 95%CI, 2.10-5.92). On the contrary, a lower reporting probability was found for semaglutide than liraglutide (ROR, 0.51; 95%CI, 0.38-0.69). CONCLUSIONS Suicidal events were mostly reported with semaglutide and liraglutide, which were also associated with significantly higher reporting probabilities compared to other GLP1 RAs. Although this study provides the reporting frequencies of suicide-related events with GLP-1 RAs, establishing causality requires further investigation, which will probably be addressed by the Pharmacovigilance Risk Assessment Committee of the European Medicine Agency in the future.

Women with familial hypercholesterolemia phenotype are undertreated and poorly controlled compared to men. Sci Rep 2023; 13:1492. [PMID: 36707646 PMCID: PMC9883524 DOI: 10.1038/s41598-023-27963-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Accepted: 01/10/2023] [Indexed: 01/29/2023] Open
Abstract
Familial hypercholesterolemia (FH) is an autosomal dominant disease that has a prevalence of approximately 1/250 inhabitants and is the most frequent cause of early coronary heart disease (CHD). We included 1.343.973 women and 1.210.671 men with at least one LDL-c measurement from the Catalan primary care database. We identified 14.699 subjects with Familial hypercholesterolemia-Phenotype (FH-P) based on LDL-c cut-off points by age (7.033 and 919 women, and 5.088 and 1659 men in primary and secondary prevention, respectively). Lipid lower therapy (LLT), medication possession ratio (MPR) as an indicator of adherence, and number of patients that reached their goal on lipid levels were compared by sex. In primary and secondary prevention, 69% and 54% of women (P = 0.001) and 64% and 51% of men (P = 0.001) were on low-to-moderate-potency LLT. Adherence to LLT was reduced in women older than 55 years, especially in secondary prevention (P = 0.03), where the percentage of women and men with LDL-c > 1.81 mmol/L were 99.9% and 98.9%, respectively (P = 0.001). Women with FH-P are less often treated with high-intensity LLT, less adherent to LLT, and have a lower probability of meeting their LDL-c goals than men, especially in secondary prevention.

Abstract
Purpose The study aimed to analyze, in hypercholesterolemic patients under statin medication, patient characteristics and their lipid profile at baseline, the therapeutic pathway, and the pharmaco-utilization, using real-world data in Italy. Patients and Methods A retrospective study was conducted using administrative databases of a sample of entities covering 6.5 million health-assisted individuals. Between January 2010 and June 2019, patients with non-familial hypercholesterolemia (nFH) were identified by 1) ≥1 low-density lipoprotein cholesterol (LDL-C) measurement (LDL-C assessment date was the index-date) and 2) statin prescription during 6 months before the index-date (pharmaco-utilization period). FH patients were defined by LDL-C evaluation, statin treatment during the pharmaco-utilization period, and a score ≥6 according to the Dutch Lipid Clinic Network criteria. nFH patients were divided into four exclusive cohorts based on CV-risk class: 1) with previous CV disease (CVD); 2) with diabetes mellitus; 3) with mixed-dyslipidemia diagnosis; 4) in primary-prevention. Based on LDL-C index values, patient was defined with LDL-C “controlled” if its levels were ≤70mg/dl (CVD), ≤100mg/dl (diabetes, FH), ≤130mg/dl (mixed-dyslipidemia, primary-prevention). Results Overall 164,161 nFH patients were included (mean age 72 years, 51% male); of these, 46,782 (28.5%) were CVD (mean age 74 years, 66% male), 34,803 (21.2%) were diabetic (mean age 72 years, 51% male), 1617 (1%) were with mixed-dyslipidemia (mean age 71 years, 48% male) and 80,959 (49.3%) were in primary-prevention (mean age 71 years, 42% male). The proportion of nFH patients with controlled LDL-C was 41.2% for CVD, 73.6% for diabetic, 80.7% for mixed-dyslipidemia, and 79.5% for primary-prevention patients; 49% of nFH patients were adherent to therapy. Overall, 1287 FH patients (mean age 64 years, 42% male) were included; in 39.2% of the patients, LDL-C was controlled, and 44% of the patients were adherent to therapy. Conclusion The results of this study highlighted non-optimal therapeutic management of hypercholesterolemic patients in Italian clinical practice, with a notable quote of patients non-adherent to therapy.

Abstract
BACKGROUND /Objectives: Pancreatic ductal adenocarcinoma (PDAC) has a higher incidence in men compared to women, although the difference in known risk factors cannot explain this disparity completely. Reproductive and hormonal factors have been demonstrated in pre-clinical studies to influence pancreatic carcinogenesis, but the few published data on the topic are inconsistent. The aim was to investigate the role of reproductive and hormonal factors on PDAC occurrence in women. METHODS We conducted a unicenter case-control study; PDAC cases were matched to controls by age with a 1:2 ratio. Risk factors were screened through questionnaires about gynecologic and medical history. Comparisons were made using Chi-square and Fisher's exact tests where appropriate for categorical variables and Student's t-test for continuous variables. Logistic regression was used to calculate Odds Ratios (ORs) and their 95% confidence intervals (CI). Multivariable logistic regression models were adjusted for potential confounders. RESULTS 253 PDAC and 506 matched controls were enrolled. At logistic regression multivariable analysis adjusted for confounding factors, older age at menopause (OR:0.95 per year; 95% CI:0.91-0.98; p = 0.007), use of Oral Contraceptives (OR:0.52; 95% CI:0.30-0.89; p = 0.018), use of Hormonal Replacement Therapy (OR:0.31; 95% CI:0.15-0.64; p = 0.001), and having had two children (OR:0.57; 95% CI:0.38-0.84; p = 0.005) were significant, independent protective factors for the onset of PDAC. CONCLUSIONS These data confirm some previous findings on menopause age and number of births while, to our knowledge, this is the first study to show a protective effect of HRT and OC use. The results collectively support the hypothesis that exposure to estrogens plays a protective role towards PDAC.

Abstract
Introduction. Lipid-lowering drugs, especially statins, have shown great relevance in preventing and treating cardiovascular diseases. Objective. To determine the prescription patterns of lipid-lowering drugs and the variables associated with their use in a Colombian population. Materials and methods. This is a cross-sectional descriptive study. From a drugdispensing database of approximately 4.5 million Colombian health system affiliates, patients of all ages and both sexes treated with lipid-lowering agents (statins, fibrates, ezetimibe) were identified between January and March, 2017. Demographic, pharmacological and co-medication variables were included. Results. In total, 103,624 patients were identified as being treated with lipid-lowering agents. The average age was 67.5 years, and 49.8% were 65 years or older. Women comprised 58.0% of the patients. Statins were the most used (n=96,910; 93.5%), and atorvastatin (n=80,812; 78.0%) and lovastatin (n=12,621; 12.2%) were the most frequent. The mean atorvastatin dose was 30.3 mg/day, and 49.9% of its users received presentations of 40 mg or more. A total of 9,258 (8.9%) patients received fibrates, and only 780 (0.8%) were taking ezetimibe. Of this population, 94.9% were treated with lipid-lowering monotherapy, and 97.3% (n=100,813) had co-medication for their comorbidities, with the most frequent being antihypertensive (89.1%), antiplatelet (57.8%), antidiabetic (31.5%) and antiulcerative agents (34.2%). Conclusions. Atorvastatin is currently the most frequently used lipid-lowering drug in this group of Colombian patients, especially in monotherapy and at doses close to the defined daily dose. Only half received high-intensity doses. New studies are required to verify the efficacy of these therapies.

Abstract
Background: The competition for and market dynamics of generic medicines can be understood by analyzing manufacturers' behavior. In this study, we analyzed the various types of generic atorvastatin and rosuvastatin that were introduced onto the South Korean market from 2002 to 2018 and their corresponding manufacturers. Methods: Based on publicly available data, we selected drugs containing atorvastatin and rosuvastatin as active ingredients for the analysis. We calculated the time between the date of marketing approval for the first generic and that of the remaining generics. Then, we categorized manufacturers that marketed generics into first movers and latecomers. Results: We confirmed that many manufacturers have marketed generic drugs in South Korea and that manufacturers can be categorized as first movers and latecomers. Interestingly, latecomers account for a large portion of the manufacturers of generics, and they have entered the market steadily, even after the market matured with a number of manufacturers. Additionally, the characteristics of the manufacturers were closely related to manufacturers' behaviors in the market. Conclusions: The order-of-entry effect, which is commonly observed in other markets, is marginal in the South Korean market, and this phenomenon is mainly explained by the rare price competition among generic manufacturers.

Abstract
Background Older individuals (aged ≥65 years) are commonly prescribed statins but may experience a range of barriers in adhering to therapy. The factors associated with poor statin adherence and/or discontinuation among this population have not been comprehensively reviewed. Methods We conducted a systematic review to identify English articles published through December 12, 2016 that reported factors associated with nonadherence and/or discontinuation of statins among older persons. Data were pooled via random-effects meta-analysis techniques. Results Forty-five articles reporting data from more than 1.8 million older statin users from 13 countries were included. The factors associated with increased statin nonadherence were black/non-white race (odds ratio [OR] 1.66, 95% confidence interval [CI] 1.39-1.98), female gender (OR 1.08, 95% CI 1.03-1.13), current smoker (OR 1.12, 95% CI 1.03-1.21), higher copayments (OR 1.38, 95% CI 1.25-1.52), new user (OR 1.58, 95% CI 1.21-2.07), lower number of concurrent cardiovascular medications (OR 1.08, 95% CI 1.06-1.09), primary prevention (OR 1.49, 95% CI 1.40-1.59), having respiratory disorders (OR 1.17, 95% CI 1.12-1.23) or depression (OR 1.11, 95% CI 1.06-1.16), and not having renal disease (OR 1.09, 95% CI 1.04-1.14). The factors associated with increased statin discontinuation were lower income status (OR 1.20, 95% CI 1.06-1.36), current smoker (OR 1.14, 95% CI 1.06-1.23), higher copayment (OR 1.61, 95% CI 1.53-1.70), higher number of medications (OR 1.04, 95% CI 1.01-1.06), presence of dementia (OR 1.18, 95% CI 1.02-1.36), cancer (OR 1.22, 95% CI 1.11-1.33) or respiratory disorders (OR 1.19, 95% CI 1.05-1.34), primary prevention (OR 1.66, 95% CI 1.24-2.22), and not having hypertension (OR 1.13, 95% CI 1.07-1.20) or diabetes (OR 1.09, 95% CI 1.04-1.15). Conclusion Interventions that target potentially modifiable factors including financial and social barriers, patients' perceptions about disease risk as well as polypharmacy may improve statin use in the older population.

Abstract
BACKGROUND Adverse drug events (ADEs) are a significant cause of emergency department (ED) visits, with a major impact on healthcare resource utilization. A multicentre observational study, aimed to describe frequency, seriousness and preventability of ADEs reported in four EDs, was performed in Sicily (Italy) over a 1-year period. METHODS Two trained monitors for each ED supported clinicians in identifying ADEs of patients admitted to EDs between June 1st, 2013 and May 31st, 2014 through a systematic interview of patients or their caregivers and with an additional record review. A research team analyzed each case of suspected ADE, to make a causality assessment applying the Naranjo algorithm and a preventability assessment using Schumock and Thornton criteria. Absolute and percentage frequencies with 95% confidence interval (CI) and medians with interquartile ranges (IQR) were estimated. Logistic regression models were used to evaluate independent predictors of serious and certainly preventable ADEs. RESULTS Out of 16,963 ED visits, 575 (3.4%) were associated to ADEs, of which 15.1% resulted in hospitalization. ADEs were classified as probable in 45.9%, possible in 51.7% and definite in 2.4% of the cases. Moreover, ADEs were considered certainly preventable in 12.3%, probably preventable in 58.4%, and not preventable in 29.2% of the cases. Polytherapy influenced the risk to experience a serious, as well as a certainly preventable ADE. Whilst, older age resulted an independent predictor only of serious events. The most common implicated drug classes were antibiotics (34.4%) and anti-inflammatory drugs (22.6%). ADEs due to psycholeptics and antiepileptics resulted preventable in 62.7 and 54.5% of the cases, respectively. Allergic reactions (64%) were the most frequent cause of ADE-related ED visits, followed by neurological effects (10.2%) that resulted preventable in 1.9 and 37.3% of the cases, respectively. CONCLUSION ADEs are a frequent cause of ED visits. The commonly used antibiotics and anti-inflammatory drugs should be carefully managed, as they are widely involved in mild to severe ADEs. Polytherapy is associated with the occurrence of serious, as well as certainly preventable ADEs, while older age only with serious events. A greater sensitivity to drug monitoring programs among health professionals is needed.

Abstract
OBJECTIVE This study analysed utilisation of statins for new statin users and assessed market dynamics of statins in South Korea. DESIGN This study is a retrospective cohort study. SETTING The yearly claims data for statins were retrieved from the National Health Insurance Service-National Sample Cohort. MAIN OUTCOME MEASURE We are interested in new statin users during 2003-2015 in Korea. Information on prescribed statins, including intensity of statins and entry of new and follow-on statins in the market, and healthcare institutions that prescribed the statins were also collected. In time series analysis, we estimated the effect of introduction of generics in the market, specifically for newly prescribed statin users. RESULTS This 13-year longitudinal study of a sample cohort provided by the National Health Insurance Service found that the incidence of new statin user increase from 838.1/100 000 persons in 2003 to 1626.9/100 000 persons in 2015. Most new users were initiated on a monotherapy that was prescribed at primary healthcare institutions. However, the statin market for new users were quite dynamic in Korea. First, the most commonly prescribed statin changed several times during the study period. Second, the use of moderate-intensity statins increased from 57% in 2003 to 92% in 2015. In line with this result, we could not observe substantial differences in prescription of statins in groups having selected diseases history. Lastly, we found market invasion or switch of statins among new statin users, specifically at primary healthcare institutions. CONCLUSION Similar to other countries, the incidence of new statin users has been increased in Korea. However, the statin market in Korea is quite dynamic compared with other countries. Interestingly, discounted price of originals after the introduction of generics immediately expand markets or substitute the market particularly in primary healthcare institutions in Korea.

Abstract
PURPOSE A rational use of statins has a major and increasing importance in public health and allocation of financial resources by the health insurance funds (HIFs). The aim of this study was to evaluate the market share and utilization trends of statins in the Republic of Macedonia (R. Macedonia) from 2013 to 2016. MATERIALS AND METHODS A retrospective analysis and data comparison for the utilization of HMG-CoA inhibitors (C10AA) in R. Macedonia from 2013 to 2016 were conducted. The data obtained from HIF, IMS Health, pharmaceutical industry and marketing authorization holders (MAHs) were evaluated through defined daily doses per 1000 insurers per day (DDD/TID). RESULTS Cardiovascular drugs are the most commonly prescribed and utilized drugs in R. Macedonia. The HIF cost for cardiovascular disease (CVD) increased to €2,243,777.00 in the period from 2013 to 2016. Since 2012, the reimbursement shows that atorvastatin accounts for the highest expenditure reaching €2,162,958.00 while rosuvastatin reached €1,645,860.00 in 2016. The increased consumption of statins is confirmed from the records obtained from IMS Health databases in the evaluated period in R. Macedonia suggesting increased expenditures with total growth of 35.65% reaching €4,421,280.24 in 2016. Evident growth of statin consumption is confirmed from the data obtained from the pharmaceutical industry and MAH. The statin use increased from 42.347 DDD/TID in 2013 to 71.697 DDD/TID in 2016, although it is lower in comparison to other European Union (EU) countries (1.1-2.5-fold). CONCLUSION The rapid increase in the consumption of statins can be attributed mostly to an increase in the consumption volume. It is inevitable to widen the price reduction concept with initiatives that may control statin consumption amounts with measures such as educational programs for rational drug utilization and targeting eligible population.

Abstract
Background: Adverse drug reactions (ADRs) are an important public health problem, representing a major cause of morbidity and mortality. However, several countries have no recent studies available. Since 2014, a prospective active pharmacovigilance project, aimed to improve ADRs monitoring in hospital wards (FORWARD) was performed in Sicily. This study, as part of FORWARD project, was aimed to describe ADRs occurred during the hospital stay in Internal Medicine wards. ADRs related to hospital admission, characteristics and preventability of ADRs were also evaluated. Methods: Demographic, clinical, and pharmacological data on patients admitted to six wards of Internal Medicine, from 2014 to 2015, were collected by trained, qualified monitors, who screened all medical records. The rate of ADRs occurred during hospital stay and those leading to hospitalization were analyzed. A descriptive analysis of the reactions, suspected drugs, and associated factors was performed according to the setting analyzed. Results: During the study period, 4,802 admissions were recorded; in 3.2% of them ADRs occurred during hospital stay while in 6.2%, admission was due to ADRs. The duration of hospital stay was longer in patients who experienced ADRs during hospitalization, compared to patients without ADRs [median days 12 (Q1–Q3: 8–17) vs. 9 (6–13)]; p < 0.001). Females [OR1.39 (95% CI 1.03–1.93)] and patients taking ≥ 4 drugs [OR1.46 (95% CI 1.06–2.03)] were more likely to experience ADRs during hospital stay, as well as to be admitted because of ADRs [female: OR1.75 (95% CI 1.37–2.24); ≥ 4 drugs: OR2.14 (95% CI 1.67–2.74)]. The most frequent ADRs occurred during hospital stay were cutaneous (26.8%), general (13.4%), vascular (13.4%), and cardiac (11.5%) disorders and the drug classes mainly involved were anti-bacterials (38.2%) and antithrombotic agents (21.7%). ADRs were serious in 44.6% and probably preventable in 69.4%. Gastrointestinal (27.7%), hematological (26.5%), metabolic (18.1%), and nervous (16.1%) disorders were the main ADRs cause of hospitalization, primarily due to antithrombotic agents (39.0%) RAS-inhibitors (13.9%), NSAIDs (11.9%), and diuretics (9.0%). Only 12.9% of them was not preventable. Conclusion: Adverse drug reactions occurred during hospitalization or contributing to admission to Internal Medicine wards were considerable and most of them were preventable. Females and patients taking many medications were more likely to present ADRs both during hospital stay or as cause of admission.

Abstract
BACKGROUND Statin treatment is often associated with poor adherence, which may be due to the onset of adverse drug reactions (ADRs). We investigated on potential risk factors related to preventable cases of statin-induced ADRs and to the discontinuation of statin therapy. METHODS We performed a study using the database of Italian spontaneous reporting. The target population for the preventability assessment was all patients with suspected statin-induced ADRs deriving from Campania Region (a territory of Southern Italy) between 2012 and 2017. Additionally, a local sentinel surveillance site involving General Practitioners was selected to countercheck in routine clinical practice the role of ADRs for statin discontinuation. RESULTS In total, 34 of 655 (5.19%) regional cases were preventable and among detected risk factors 90.0% was related to healthcare professionals' practices and 10.0% to patient behaviour. In 81.4% (533/655) of cases, statin therapy was discontinued due to ADRs, mainly classified as not serious and associated with a positive prognosis. These results were also confirmed in the active sentinel site. CONCLUSIONS Our findings suggest an inappropriate use of statins among the identified preventable cases and a potential inappropriate statin discontinuation due to ADRs. These factors may be useful for targeting interventions to improve statin adherence.

Abstract
BACKGROUND AND AIMS Statin utilization and lipid goal achievement were estimated in a large sample of Italian patients at high/very-high cardiovascular (CV) risk. METHODS Patients aged ≥18 years with a valid low-density lipoprotein cholesterol (LDL-C) measurement in 2015 were selected from the IMS Health Real World Data database; non-high-density lipoprotein cholesterol (non-HDL-C) was assessed in those with available total cholesterol measurements. Index dates were defined as the last valid lipid measurement in 2015. Patients were hierarchically classified into mutually exclusive risk categories: heterozygous familial hypercholesterolemia (primary and secondary prevention), atherosclerotic CV disease (including recent acute coronary syndrome [ACS], chronic coronary heart disease, stroke, and peripheral arterial disease), and diabetes mellitus (DM) alone. Statin and non-statin lipid-modifying therapy (LMT) use, and European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guideline-recommended goal attainment, were assessed. RESULTS Among 66,158 patients meeting selection criteria, the overall rate of LMT prescriptions was 53.3%, including 7.7% on high-intensity statin therapy. Statin use was highest for recent ACS and lowest for DM alone. LDL-C goal attainment was 16.0% for <1.8 mmol/l and 45.0% for <2.5 mmol/l; 24.3% reached non-HDL-C <2.6 mmol/l and 52.2% were at <3.3 mmol/l. Goal achievement was greatest with high-intensity statin use. CONCLUSIONS Statin use in this cohort was consistent with previous reports in Italian patients at high/very-high CV risk, and low relative to statin use in other European countries. The low rate of ESC/EAS lipid goal attainment observed was consistent with outcomes of other European studies.

Abstract
Data on the association between aspirin and statin use and Pancreatic Ductal AdenoCarcinoma (PDAC) risk are conflicting. These drugs are often co-prescribed, but no studies evaluated the potential combined or confounding effect of the two at the same time. We aimed to investigate the association between aspirin and statin exclusive and combined use and PDAC occurrence. Data on environmental factors, family and medical history were screened in a case-control study. PDAC cases were matched to controls for age and gender. Power calculation performed ahead. Odds ratios (OR) and 95% confidence intervals(CI) were obtained from multivariable logistic regression analysis. In 408 PDAC patients and 816 matched controls, overall statin (OR 0.61; 95%CI,0.43-0.88), but not aspirin use was associated to reduced PDAC risk. Compared to non-users, exclusive statin (OR 0.51; 95%CI,0.32-0.80) and exclusive aspirin users (OR 0.64; 95%CI,0.40-1.01) had reduced PDAC risk. Concomitant statin and aspirin use did not further reduce the risk compared with statin use alone and no interaction was evident. Statin protective association was dose-dependent, and consistent in most subgroups, being stronger in smokers, elderly, obese and non-diabetic patients. The present study suggests that statin use is associated to reduced PDAC risk, supporting a chemopreventive action of statins on PDAC.

Abstract
BACKGROUND Several conditions can modify the intestinal absorption of levothyroxine tablets, with potential consequences on their therapeutic effect. Pre-dosed ampoules and oral drops have been recently made available to overcome this limitation. AIMS To describe the pattern of use of different formulations of levothyroxine in a general population of Southern Italy and to perform an exploratory analysis investigating the effect of switching from levothyroxine tablets to oral liquid formulations. METHODS Data were extracted from the Caserta Local Health Unit database. All patients receiving at least one levothyroxine prescription during the years 2009-2015 were identified. 1-year incidence of use of formulation-specific levothyroxine was calculated. Switchers between levothyroxine tablets and oral liquid formulations were identified and the frequency of thyroid-stimulating hormone measurement within 2 years prior and after the switch date was explored. RESULTS Overall, 56,354 levothyroxine users were included in the study. Of these, 55,147 patients received at least one prescription for tablets (97.9%), 1867 pre-dosed ampoules (3.3%) and 1550 oral drops (2.8%). The proportion of levothyroxine users receiving oral liquid formulations slightly increased over time. Patients switching from tablets to oral liquid formulations showed a statistically significant reduction in the number of thyroid-stimulating hormone measurements after switching from tablets, especially in presence of drugs interacting with levothyroxine potentially altering its absorption. CONCLUSIONS Use of levothyroxine oral liquid formulations is increasing over time even though their use is still limited in a general population of Southern Italy. Our exploratory analysis showed that the frequency of thyroid-stimulating hormone measurement was reduced in patients switching from levothyroxine tablet to new formulations.

Abstract
Objectives: To investigate the occurrence of adverse events (AEs) in naïve patients receiving biotech drugs. Design: A prospective observational study. Setting: Onco-hematology, Hepato-gastroenterology, Rheumatology, Dermatology, and Neurology Units in Campania Region (Italy). Participants: 775 patients (53.81% female) with mean age 56.0 (SD 15.2). The mean follow-up/patient was 3.48 (95% confidence interval 3.13–3.84). Main outcome measures: We collected all AEs associated to biotech drugs, including serious infections and malignancies. Serious AEs were defined according to the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use, clinical safety data management: definitions and standards for expedited reporting E2A guideline. Results: The majority of the study population was enrolled in Onco-hematology and Rheumatology Units and the most common diagnosis were hematological malignancies, followed by rheumatoid arthritis, colorectal cancer, breast cancer, and psoriatic arthritis. The most commonly prescribed biotech drugs were rituximab, bevacizumab, infliximab, trastuzumab, adalimumab, and cetuximab. Out of 775 patients, 320 experienced at least one AE. Most of patients experienced AEs to cetuximab therapy, rituximab and trastuzumab. Comparing female and male population, our findings highlighted a statistically significant difference in terms of AEs for adalimumab (35.90% vs. 7.41%, p < 0.001) and etanercept (27.59% vs. 10.00%, p = 0.023). Considering all biotech drugs, we observed a peak for all AEs occurrence at follow-up 91–180 days category. Bevacizumab, brentuximab, rituximab, trastuzumab and cetuximab were more commonly associated to serious adverse events; most of these were possibly related to biotech drugs, according to causality assessment. Three cases of serious infections occurred. Conclusions: The results of our study demonstrated that the majority of AEs were not serious and expected. Few cases of serious infections occurred, while no case of malignancy did. Overall, the safety profile of biotech drugs used in our population was similar to those observed in pivotal trials. Notwithstanding the positive results of our study, some safety concerns still remain unresolved. In order to collect more effectiveness and safety data on biotech drugs, the collection and analysis of real world data should be endorsed as well as the management of post-authorization studies.

Abstract
OBJECTIVE To assess suitability and comparability of the most common methods of treatment adherence and persistence assessment, as applied to the same pharmacy dataset. METHODS Data on drugs prescribed for cardiovascular primary prevention to participants in the Aragon Workers' Health Study (AWHS) were collected from a regional electronic drug prescription database. Several different approaches were used to measure treatment adherence (with the medication possession ratio [MPR]) and proportion of days covered [PDC]) and persistence in new users by therapeutic subgroup. Defined daily dose (DDD) was used as a proxy of the number of days' supply, or substituted with surrogate daily dose values. RESULTS Higher mean adherence values and proportions of adherent patients were obtained using MPR versus PDC, with additional differences depending on the approach used. The proportion of adherent patients was lowest for oral antidiabetics (14.4%-30.6%) and highest for antihypertensives (70.2%-82.1%). The use of surrogate daily dose values increased adherence for antidiabetics and statins and decreased adherence for antihypertensives. After a 1 year follow-up, treatment persistence was observed for 21.1%, 58.7%, and 29.5% of antidiabetic, antihypertensive and statin users, respectively. CONCLUSIONS Our findings indicate that use of multiple measures of treatment adherence and persistence provides a more complete overview of medication use patterns, and certain limitations associated with DDD for some drug groups can be overcome with replacement by surrogate doses. The PDC indicator seems to provide a more accurate reflection of patient behavior and treatment continuity than the MPR. Any comparison of adherence/persistence should always consider the method used, variables analyzed, and corresponding data collection process.

Genistein Supplementation and Cardiac Function in Postmenopausal Women with Metabolic Syndrome: Results from a Pilot Strain-Echo Study. Nutrients 2017; 9:nu9060584. [PMID: 28590452 PMCID: PMC5490563 DOI: 10.3390/nu9060584] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2017] [Revised: 05/30/2017] [Accepted: 05/31/2017] [Indexed: 12/26/2022] Open
Abstract
Genistein, a soy-derived isoflavone, may improve cardiovascular risk profile in postmenopausal women with metabolic syndrome (MetS), but few literature data on its cardiac effects in humans are available. The aim of this sub-study of a randomized double-blind case-control study was to analyze the effect on cardiac function of one-year genistein dietary supplementation in 22 post-menopausal patients with MetS. Participants received 54 mg/day of genistein (n = 11) or placebo (n = 11) in combination with a Mediterranean-style diet and regular exercise. Left ventricular (LV) systolic function was assessed as the primary endpoint, according to conventional and strain-echocardiography measurements. Also, left atrial (LA) morphofunctional indices were investigated at baseline and at the final visit. Results were expressed as median with interquartile range (IQ). A significant improvement of LV ejection fraction (20.3 (IQ 12.5) vs. −1.67 (IQ 24.8); p = 0.040)), and LA area fractional change (11.1 (IQ 22.6) vs. 2.8 (9.5); p = 0.034)) were observed in genistein patients compared to the controls, following 12 months of treatment. In addition, body surface area indexed LA systolic volume and peak LA longitudinal strain significantly changed from basal to the end of the study in genistein-treated patients. One-year supplementation with 54 mg/day of pure genistein improved both LV ejection fraction and LA remodeling and function in postmenopausal women with MetS.

Abstract
OBJECTIVE Statins have been commonly used to treat patients with hypercholesterolaemia and to prevent cardiovascular disease (CVD) worldwide. This study examined trends in use of statins in Taiwan from 2002 to 2011. DESIGN This is a retrospective observational study focusing on the utilisation of statins. SETTING The monthly claims data for statins between 2002 and 2011 were retrieved from Taiwan's National Health Insurance Research Database. MAIN OUTCOME MEASURES We calculated the yearly prescription rate per new user for each statin. Products were classified as high-intensity/moderate-intensity/low-intensity statins by type of statin and dosage. Users were also classified based on disease histories. RESULTS The number of statin users increased from 10 299 (~1.4% of adults) in 2002 to 50 687 (~6.3% of adults) in 2011. Atorvastatin was the most commonly used agent (28.4%-36.7%) during the study period. After 2007, simvastatin ranked second with 21.7% market share, followed by rosuvastatin, a newer agent that exhibited a substantial growth in prescription rates (3.4% in 2005 and 19.5% in 2011). In 2011, 94.0% of new statin users used statin monotherapies, and 6.0% used combination therapies. Use of moderate-intensity statins increased from 49.0% in 2002 to 71.0% in 2011, while high-intensity statins remained low. Patients with history of coronary events or cerebrovascular events were more likely to be prescribed higher intensity statins compared with those without. Prescribing of higher intensity statins was not greater among people with diabetes compared with those without during 2007-2011. Selection of statins did not differ between people with versus without history of myopathy or liver injury. CONCLUSION Atorvastatin was the most commonly used statin in Taiwan during 2002-2011. While patients with history of CVD were more likely to be prescribed higher intensity statins compared with those without, this difference was not found comparing those with and without diabetes.

Abstract
INTRODUCTION AND OBJECTIVES The aim of this study was to assess patterns of treatment persistence in a cohort of male Spanish workers receiving statin therapy for primary prevention of cardiovascular disease. METHODS This descriptive study was conducted within the framework of the prospective longitudinal Aragon Workers' Health Study (N = 5400). Incident male statin users were identified based on data collected from the regional government's medication consumption information system. Patterns of treatment persistence with statins prescribed for primary cardiovascular disease prevention were assessed and the relevance of potential predictors explored. RESULTS Among the 725 new statin users, less than one third remained persistent during the 1 year of follow-up. About 15% of nonpersistent users discontinued statin therapy after dispensation of the first prescription; of these, 42.1% did not recommence treatment within the following year. Factors reducing the likelihood of treatment discontinuation were older age (HR, 0.55; 95%CI, 0.39-0.77) and cotreatment with antihypertensive drugs (HR, 0.68; 95%CI, 0.56-0.82). No association was observed between treatment persistence and cotreatment with antidiabetic or antithrombotic drugs, baseline low-density lipoprotein levels, or total cholesterol levels. However, persistence was influenced by the type of statin first prescribed. CONCLUSIONS Our analysis of a cohort of healthy male workers revealed poor statin persistence. These findings underscore the need for a better understanding of patterns of statin use, especially in apparently healthy individuals, and for the incorporation of patient behavior into prescribing decisions.

Abstract
OBJECTIVE To identify and assess studies published over a 10 year period up to February 2016 which measure adherence or persistence with statins, to summarize their methods, strengths and weaknesses and to summarize evidence linking statin adherence/persistence with risk of cardiovascular events. METHODS Electronic databases and abstracts from four major cardiovascular disease conferences were searched from January 2005 to February 2016. The study selection process was performed by two reviewers working independently. Studies were included if they reported data regarding patient adherence or persistence with statins in adults with primary hypercholesterolemia, using any type of study design or length of follow-up. One reviewer extracted the study data and assessed study quality, which was checked by a second reviewer independently. Given the heterogeneity between the included studies a narrative critique and summary is presented. RESULTS We report on 84 real world studies which aimed to assess adherence or persistence with statins. The majority of studies concluded that good adherence/persistence was associated with reduction in cardiovascular events and mortality. In two studies high intensity statin regimens were associated with poorer patient adherence when compared to low intensity statins. Adherence and persistence with statin therapy also has an impact on hospitalization costs and other cardiovascular disease (CVD) related costs. CONCLUSIONS Adherence and persistence are associated with a reduction in CVD events and mortality. There was limited evidence to suggest that high intensity statin regimens are associated with poorer treatment adherence when compared to lower intensity regimens. Hence, more robust studies are required to establish this association. As recommended by the 2013 ACC/AHA, 2016 ESC and several other clinical guidelines, clinicians and pharmacy managers should regularly monitor statin therapy adherence.

Abstract
OBJECTIVES To analyse if there are sociodemographic differences in the utilisation of statins 9-12 months after ischaemic stroke or transitory ischaemic attack. METHODS Anonymised linkage of registry data on all patients >18 years discharged from the hospitals in Stockholm, Sweden 2006-2010 with diagnosis of ischaemic stroke (ICD-10: I63.0-9) or TIA (ICD-10: G45.9) was performed. Data on hospitalisations and diagnoses were collected from the Stockholm County Council administrative databases on healthcare consumption. Dispensed prescriptions with statins and, for comparative purposes, antihypertensive agents 9-12 months after discharge were acquired from the National Swedish Prescribed Drug Register. Data about socioeconomic factors were obtained from Statistics Sweden. The dispensing of statins and antihypertensive agents, relative to sociodemographic variables were analysed. Using logistic regression odds ratios, crude, and adjusted with education, income, origin of birth, age, and sex as predictors where calculated. RESULTS Of 24 312 patients with ischaemic stroke/TIA, 19 335 were alive 12 months after discharge. Statins were dispensed to 44% of all patients in the cohort, more frequently to men of all age groups, to patients with higher education, and to those with higher income. Antihypertensive agents were dispensed to 68% of all patients and there were no differences related to sex and income whilst patients with lower education were dispensed with antihypertensives more frequently. CONCLUSION We find a low utilisation of statins one year after ischaemic stroke/TIA. Patients with low education, low income, and female sex were dispensed fewer prescriptions of statins indicating a need for improvement.

Abstract
BACKGROUND AND OBJECTIVES Diabetes mellitus in patients with chronic kidney disease (CKD) is known as diabetic kidney disease (DKD). Pharmacological management of DKD is challenging due to reduced renal excretion of some antidiabetic drugs. The aim of this population-based study was to explore antidiabetic drug use in DKD patients from Southern Italy. METHODS The Arianna database from Caserta Local Health Unit was used. Diabetic patients with incident CKD [first diagnosis date: index date (ID)] were identified by searching for specific ICD9-CM codes among hospital discharge diagnoses/procedures and/or indication of use associated with drug prescriptions. To evaluate any change in the use of antidiabetic drugs after the CKD diagnosis, the prevalence of antidiabetic drug use among DKD patients was calculated within 1 year prior to/after ID and after dialysis entry. A Kaplan-Meier analysis was used to assess the time to discontinuation of antidiabetic drugs after CKD diagnosis. The frequency of antidiabetic drugs contraindicated in renal disease in DKD patients was measured. RESULTS Overall, 725 diabetic patients (mean age 72.8 ± 11.4 years) had incident CKD from 2006 to 2011. The use of combination antidiabetic drugs, biguanides and sulphonamides decreased by approximately 10, 7 and 5%, respectively, after the ID. The use of insulins increased by 10% after the ID and by 20% after entry into dialysis. The use of antidiabetic drugs not contraindicated in CKD decreased marginally after the diagnosis of CKD. CONCLUSION In a general practice of Southern Italy the management of diabetes mellitus changed only marginally in newly diagnosed CKD patients, suggesting a therapeutic inertia on the part of prescribers.

Abstract
OBJECTIVES To estimate rates of discontinuation and restarting of statins, and to identify patient characteristics associated with either discontinuation or restarting. DESIGN Prospective open cohort study. SETTING 664 general practices contributing to the Clinical Practice Research Datalink in the United Kingdom. Data extracted in October 2014. PARTICIPANTS Incident statin users aged 25-84 years identified between January 2002 and September 2013. Patients with statin prescriptions divided into two groups: primary prevention and secondary prevention (those already diagnosed with cardiovascular disease). Patients with statin prescriptions in the 12 months before study entry were excluded. MAIN OUTCOME MEASURES Discontinuation of statin treatment (first 90 day gap after the estimated end date of a statin prescription), and restarting statin treatment for those who discontinued (defined as any subsequent prescription between discontinuation and study end). RESULTS Of 431 023 patients prescribed statins as primary prevention with a median follow-up time of 137 weeks, 47% (n=204 622) discontinued treatment and 72% (n=147 305) of those who discontinued restarted. Of 139 314 patients prescribed statins as secondary prevention with median follow-up time of 182 weeks, 41% (n=57 791) discontinued treatment and 75% (43 211) of those who discontinued restarted. Younger patients (aged ≤50 years), older patients (≥75 years), women, and patients with chronic liver disease were more likely to discontinue statins and less likely to restart. However, patients in ethnic minority groups, current smokers, and patients with type 1 diabetes were more likely to discontinue treatment but then were more likely to restart, whereas patients with hypertension and type 2 diabetes were less likely to discontinue treatment and more likely to restart if they did discontinue. These results were mainly consistent in the primary prevention and secondary prevention groups. CONCLUSIONS Although a large proportion of statin users discontinue, many of them restart. For many patient groups previously considered as "stoppers," the problem of statin treatment "stopping" could be part of the wider issue of poor adherence. Identification of patient groups associated with completely stopping or stop-starting behaviour has positive implications for patients and doctors as well as suggesting areas for future research.

Abstract
BACKGROUND Lack of adherence to prescribed therapies is often a cause of suboptimal blood pressure control in patients with hypertension. To enhance patients' adherence to treatment, fixed-dose combinations of active substances with complementary mechanisms of action have been developed. An angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker (ARB) is often combined with a calcium channel blocker. Olmesartan is the most used ARB in combination therapy. In Italy, in September 2011, a fixed-dose combination of olmesartan/amlodipine (olmesartan/amlodipine 20/5 mg, 40/5 mg, or 40/10 mg) was introduced to treat patients with hypertension for whom control of blood pressure is not reached with either olmesartan or amlodipine alone. Prior research on adherence to olmesartan/amlodipine combinations was carried out in local contexts (e.g., claims databases of Italian regions or local health authorities), and/or it was limited by the fact that adherence was assessed against monotherapies already known for their low compliance profile, such as diuretics. OBJECTIVE To compare adherence with olmesartan/amlodipine fixed-dose combination (FDC) and extemporaneous combination in primary care in Italy. METHODS A nationwide, population-based study was conducted by using the Health Search IMS Health Longitudinal Patient Database. Patients aged > 17 years, affected by hypertension and treated with the FDC or extemporaneous combination of olmesartan/amlodipine, were identified. Adherence to these 2 therapeutic regimens was estimated by calculating the proportion of days covered (PDC). Patients were classified into 3 levels of adherence: high (PDC ≥ 80%), intermediate (PDC = 40%-79%), or low (PDC < 40%). RESULTS In the 6-month follow-up, FDC showed higher adherence compared with an extemporaneous combination (55.1% vs. 15.9%, P < 0.001). This difference was confirmed in a multivariable logistic regression model clustered on patient identifier (odds ratio = 6.65; 95% CI = 3.10-14.26; P < 0.001). The proportion of patients adherent to FDC varied from 60.4% for the 40/5 mg formulation to 47.5% for the 40/10 mg formulation. CONCLUSIONS These findings suggest that higher adherence may be achieved with FDCs than with extemporaneous combinations. To improve the degree of adherence, general practitioners may consider prescribing fixed combinations of antihypertensive agents as soon as monotherapies fail to achieve the expected therapeutic objective.

Abstract
BACKGROUND Numerous studies have documented the strong inverse relationship between low-density lipoprotein cholesterol (LDL-C) levels and atherosclerotic cardiovascular disease (ASCVD). However, women are less likely to be screened for hypercholesterolemia, receive lipid-lowering therapy (LLT), and achieve optimal LDL-C levels. MATERIALS AND METHODS Data were extracted from a U.S. administrative claims database between January 2008 and December 2012 for patients with established ASCVD. The earliest date of valid LDL-C value was defined as the index date. Patients were followed for ±12 months from the index date and were stratified by gender, by baseline LDL-C level, and whether they were initially treated with a LLT then propensity score matched by gender using demographic and clinical characteristics. Both descriptive statistics and logistic regression models were used to explore the association of gender with the frequency of LDL-C monitoring, LLT treatment initiation in initially untreated patients, and prescribing patterns in initially treated patients. RESULTS A total of 76,414 subjects with established ASCVD were identified; 42% of the sample was women. In the unmatched cohort, 50.3% of men and 32.0% of women were prescribed a preindex statin (p < 0.0001). Among matched patients (n = 51,764), women initially treated with LLT were significantly less likely to receive a prescription for a higher potency LLT. Even among those with LDL-C levels above 160 mg/dL, women were more likely to discontinue LLT, odds ratio (95% confidence interval) 1.8 (1.2-2.3). Female gender and older age were significant predictors of discontinuation, and the potency of the index medication was the strongest predictor of dose titration. Initially untreated women were less likely to initiate LLT treatment than men, irrespective of index LDL-C levels (p < 0.0001). CONCLUSIONS The observed disparities further reinforce the need for targeted efforts to reduce the gender gap for secondary prevention in women at high risk of cardiovascular disease.

Abstract
PURPOSE To explore the frequency of polypharmacy, functional and cognitive capacity among the elderly in Southern Italy. METHODS Population-based retrospective cross-sectional study. Information were retrieved from electronic-geriatric-forms matched by record-linkage to outpatient pharmacy-records. The following domains were collected from geriatric forms: BMI, cognitive capacity (SPMSQ), functional status (Barthel-index), mobility, living condition. Polypharmacy status was categorized as non-polypharmacy (0-4), polypharmacy (5-9) and excessive-polypharmacy (≥10). Prevalence of all variables were stratified by age and polypharmacy group. RESULTS 88,878 old people received a geriatric assessment in the years 2013-2014. Mean age was 74.8 (±7.3) years, 56.6% females. Proportion of elderly in excessive-polypharmacy increased with age (18.9% in 65-75 age-group; 27.9% in >85). Referring to cognitive capacity, the proportion of lucid patients decreased with age (from 94.3% to 58.1%), while confused patient increased with age (from 4.7% to 30.9%). Proportion of subjects with a decline in cognitive status, functional status and mobility increased in polypharmacy and excessive polypharmacy group. CONCLUSION Polypharmacy is common in people aged 65 years and older with difficulties in activities of daily living and impaired cognition. Furthermore, its prevalence raises with increasing age. Preventive strategies such us optimization of drug regimen should be performed routinely to reduce risk of adverse-health-events.

Abstract
Medication nonadherence is a prevalent public health issue that contributes to significant medical costs and detrimental health outcomes. This is especially true in patients with hypercholesterolemia, a condition affecting millions of American adults and one that is associated with increased risk for coronary and cerebrovascular events. Considering the magnitude of outcomes related to this disease, the medical community has placed significant emphasis on addressing the treatment for high cholesterol, and progress has been made in recent years. However, poor adherence to therapy continues to plague health outcomes and more must be understood and done to address suboptimal medication taking. Here we provide an overview of the reasons for poor medication adherence in patients with hypercholesterolemia and describe recent efforts to curb nonadherence. Suggested approaches for improving medication taking in patients with high cholesterol are also provided to guide practitioners, patients, and payers.
