Antibiotics (Basel) 2021; 10:antibiotics10111364. [PMID: 34827302 PMCID: PMC8615228 DOI: 10.3390/antibiotics10111364] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Revised: 10/25/2021] [Accepted: 11/05/2021] [Indexed: 12/23/2022] Open
Abstract
We examined the correlation between previous antibiotic exposure and COVID-19 severity using a population-based observational matched cohort study with patient level data obtained for more than 5.8 million people registered in SIDIAP in Catalonia, Spain. We included all patients newly diagnosed with COVID-19 from March to June 2020 and identified all their antibiotic prescriptions in the previous two years. We used a composite severity endpoint, including pneumonia, hospital admission and death due to COVID-19. We examined the influence of high antibiotic exposure (>4 regimens), exposure to highest priority critically important antimicrobials (HPCIA) and recent exposure. Potential confounders were adjusted by logistic regression. A total of 280,679 patients were diagnosed with COVID-19, 146,656 of whom were exposed to at least one antibiotic course (52.3%) during the preceding two years. A total of 25,222 presented severe COVID-19 infection (9%), and the risk of severity was highest among those exposed to antibiotics (OR 1.12; 95% CI: 1.04–1.21). Among all individuals exposed to antibiotics, high, recent and exposure to HPCIAs were correlated with increased COVID severity (OR 1.19; 95% CI: 1.14–1.26; 1.41; 95% CI: 1.36–1.46; and 1.35; 95% CI: 1.30–1.40, respectively). Our findings confirm a significant correlation between previous antibiotic exposure and increased severity of COVID-19 disease.

[PMID: 34030653 PMCID: PMC8142644 DOI: 10.1186/s12883-021-02237-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Accepted: 04/30/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Cerebrovascular disorders have occurred more frequently in some Central Nervous System (CNS) disorders, such as epilepsy. Some CNS drugs have been associated with increased stroke risk. Our aim was to estimate the risk of ischaemic stroke in patients exposed to antiepileptic drugs (AED). METHODS Population-based matched case-control study using SIDIAP database, based in electronic health records from primary healthcare from Catalonia, Spain. Cases were those patients with a registered diagnosis of first stroke during 2009-2014. Up to 10 controls were selected for each case and matched by sex, age, and geographic area and without a prior diagnosis of stroke. We considered global drug exposure to AED, past and current exposure and exposure in monotherapy to each AED. RESULTS 2,865 cases and 19,406 controls were exposed to AED during the study period. Global exposure to levetiracetam [(ORadj3.3, CI95 % 2.8-4.0)], phenytoin [ORadj1.5, CI95 % 1.2-41.9)], and valproic acid [(ORadj 1.3, CI95 % 1.1-1.6)], showed significantly association to ischaemic stroke that was also maintained with current exposure of levetiracetam [ORadj4.1, CI95 % 3.3-5.2)] and valproic acid [ORadj1.4, CI95 % 1.1-1.9)]. Current levetiracetam monotherapy showed a very high risk of ischaemic stroke [(ORadj 5.1, CI95 % 3.7-6.9)]. CONCLUSIONS Drugs used for other conditions than epilepsy (pregabalin, gabapentin) were the most used AED and both did not show a risk. Levetiracetam shows a risk for stroke even when assessed in current monotherapy. The lack of data regarding the link with diagnosis and severity in our study makes it necessary to conduct further studies to confirm or dismiss our results, focussing on levetiracetam.

Abstract
PURPOSE Adherence to pharmacological therapy for secondary prevention after an acute coronary syndrome (ACS) reduces the risk of new cardiovascular events. However, several studies showed poor adherence. Our study aim was to assess the risk of a composite endpoint of major cardiovascular events (MACE) and all-cause mortality according to the adherence to these drugs in patients after an ACS in a primary health care cohort. METHODS Population-based observational cohort study of patients with a first episode of ACS during 2009-2016. DATA SOURCE Information System for Research in Primary Care (SIDIAP) database. Drug adherence was evaluated through proportion of days covered (PDC). RESULTS We included 7152 patients and 5692 (79.6%) were adherent (PDC ≥ 75%) to the study drugs during the first year after the event. Adherents to any combination showed a significant reduction of the composite endpoint risk (HR 0.80 [0.73-0.88]), and a significant lower probability of the composite endpoint than nonadherents for all drugs, except beta-blockers. Adherents to 2 (HR 1.2; 95% CI 1.0-1.3) and 1 drug (HR 1.5; 95% CI 1.2-1.8) had higher composite endpoint risk compared to adherents to 4-3 drugs. CONCLUSION Adherence to any combination of recommended drugs reduced the composite endpoint risk, regardless the number of drugs prescribed. Adherence to a combination of 4-3 drugs was significantly associated with a reduced mortality risk compared with adherents to 2 or 1, but it was not significant for MACE.

Abstract
Objective: To evaluate the association between prematurity (by the gestational week [gw]) and ADHD during childhood. Method: Observational, matched cohort study using data from children born in a tertiary-level hospital (Hospital Universitari Vall d'Hebron, Catalonia, Spain) during 1995-2007 and data from the Information System for the Development of Research in Primary Health Care (SIDIAP database, Catalonia, Spain). Results: Prevalence of ADHD increases as gestational age decreases, 12.7% for those born ≤28 gw, compared to 3.2% for those born after the 37 gw. The risk of developing ADHD in the non-premature children tends to increase as the gw decreases (35-36 gw, hazard ratio [HR] = 1.70, 95% confidence interval [CI] [1.19, 2.44]; 33-34 gw, HR = 3.38, 95% CI [2.08, 5.50]; 29-32 gw, HR = 2.37, 95% CI [1.54, 3.63]; and ≤28 gw, HR = 5.57, 95% CI [2.49, 12.46]) Conclusion: Being born preterm is associated with a risk of developing ADHD, also in late preterm children (35-36 gw). Attention when taking care of these infants regarding their mental health must be made.

Abstract
OBJECTIVE We aimed to describe sociodemographic, comorbidities, co-medication and risk of thromboembolic events and bleeding in patients with NVAF initiating oral anticoagulants (OAC) for stroke prevention, and to estimate adherence and persistence to OAC. SETTING Primary Health Care (PHC) in the Catalan Health Institute (ICS), Catalunya, Spain. PARTICIPANTS All NVAF adult patients initiating OAC for stroke prevention in August 2013-December 2015. METHODS Population-based cohort study. Persistence was measured in patients initiating OAC in August 2013-December 2014. DATA SOURCE SIDIAP, which captures electronic health records from PHC in the (ICS), covering approximately 5.8 million people. RESULTS 51,690 NVAF patients initiated OAC; 47,197 (91.3%) were naive to OAC and 32,404 (62.7%) initiated acenocoumarol. Mean age was 72.8 years (SD 12.3) and 49.4% were women. Platelet-aggregation inhibitors were taken by 9105 (17.6%) of the patients. Persistence and adherence were estimated up to the end of follow-up. For 22,075 patients, persistence was higher among the non-naive patients [n=258 (61.7%)] than among the naive [n=11,502 (53.1%)]. Adherence was estimated for patients initiating DOAC and it was similar in naive and non-naive patients. Among the naive to DOAC treatment, those starting rivaroxaban showed a highest proportion [(n=360 (80.1%)] of good adherence at implementation (MPR>80%) while patients starting dabigatran were less adherent [n=203 (47.8%)]. CONCLUSIONS Acenocoumarol was the most frequently prescribed OAC as first therapy in NVAF patients. Non-naive to DOAC showed better persistence than naive. Rivaroxaban showed higher proportion of adherent patients during the implementation phase than apixaban and dabigatran the lowest.

Abstract
BACKGROUND A safe and effective colorectal cancer chemoprevention agent remains to be discovered. There is little evidence regarding the protective effect of chondroitin sulphate and glucosamine on colorectal cancer. We aimed to assess the association between colorectal cancer risk and the use of chondroitin sulphate and glucosamine using a large cohort with dispensed data. METHODS We performed a population-based case-control study in Catalonia using primary care reimbursed medication records (SIDIAP database). The study included 25,811 cases with an incident diagnosis of colorectal cancer and 129,117 matched controls between 2010 and 2015. RESULTS The prevalence of ever use was 9.0% (n = 13,878) for chondroitin sulphate, 7.3% (n = 11,374) for glucosamine, and 35% for regular use of nonsteroidal anti-inflammatory drugs (NSAID; n = 45,774). A decreased risk of colorectal cancer was observed among chondroitin sulphate use [OR: 0.96; 95% confidence interval (CI), 0.91-1.01], glucosamine use (OR: 0.92; 95% CI, 0.87-0.97), and concurrent use of chondroitin sulphate and glucosamine (OR: 0.83; 95% CI, 0.70-0.98). Especially for glucosamine, there was a dose-response association regarding duration and cumulative dose. The analysis stratified by simultaneous use with other NSAIDs showed that these drugs used without other NSAIDs do not reduce risk (OR: 1.06; 95% CI, 0.74-1.51). However, they may have a synergistic protective effect when used with other NSAIDs (OR: 0.80; 95% CI, 0.72-0.88). CONCLUSIONS This study does not provide strong support for an independent protective association of chondroitin sulphate or glucosamine on colorectal cancer risk in our population. However, these drugs may have a synergistic beneficial effect among NSAID users. IMPACT Chondroitin sulphate or glucosamine may contribute to the protective effect of NSAID use in colorectal cancer.

Abstract
INTRODUCTION Suicide attempts represent an important public health burden. Centralised electronic health record (EHR) systems have high potential to provide suicide attempt surveillance, to inform public health action aimed at reducing risk for suicide attempt in the population, and to provide data-driven clinical decision support for suicide risk assessment across healthcare settings. To exploit this potential, we designed the Catalonia Suicide Risk Code Epidemiology (CSRC-Epi) study. Using centralised EHR data from the entire public healthcare system of Catalonia, Spain, the CSRC-Epi study aims to estimate reliable suicide attempt incidence rates, identify suicide attempt risk factors and develop validated suicide attempt risk prediction tools. METHODS AND ANALYSIS The CSRC-Epi study is registry-based study, specifically, a two-stage exposure-enriched nested case-control study of suicide attempts during the period 2014-2019 in Catalonia, Spain. The primary study outcome consists of first and repeat attempts during the observation period. Cases will come from a case register linked to a suicide attempt surveillance programme, which offers in-depth psychiatric evaluations to all Catalan residents who present to clinical care with any suspected risk for suicide. Predictor variables will come from centralised EHR systems representing all relevant healthcare settings. The study's sampling frame will be constructed using population-representative administrative lists of Catalan residents. Inverse probability weights will restore representativeness of the original population. Analysis will include the calculation of age-standardised and sex-standardised suicide attempt incidence rates. Logistic regression will identify suicide attempt risk factors on the individual level (ie, relative risk) and the population level (ie, population attributable risk proportions). Machine learning techniques will be used to develop suicide attempt risk prediction tools. ETHICS AND DISSEMINATION This protocol is approved by the Parc de Salut Mar Clinical Research Ethics Committee (2017/7431/I). Dissemination will include peer-reviewed scientific publications, scientific reports for hospital and government authorities, and updated clinical guidelines. TRIAL REGISTRATION NUMBER NCT04235127.

Abstract
OBJECTIVE To analyze the use, effectiveness, safety and costs of stroke prevention in non-valvular atrial fibrillation (AF) in patients initiating treatment with dabigatran or vitamin K antagonists (VKA). SETTING Primary Care (PC) at the Catalan Health Institute (ICS) in Catalonia, during 2011-2013. PARTICIPANTS Patients attended in ICS PC centres with a registered diagnosis of AF who initiate dabigatran or VKA. INTERVENTIONS Not applicable MAIN MEASUREMENTS: Number of prescriptions and reimbursements of dabigatran and VKA, incidence of stroke and haemorrhages, incidence of mortatlity, number of sickness leave, and costs associated to all the previous variables. RESULTS 14,930 patients were included; 94.6% initiated VKA and 5.4%, dabigatran. Dabigatran patients were younger and with less comorbidity. There were no statistically significant differences between VKA and dabigatran in the risk of stroke, haemorrhages or death. The costs associated to AF management were higher for PC visits in the VKA group, and higher for laboratory and pharmacy in the dabigatran group, although overall costs were not statistically different. CONCLUSIONS Most patients initiated VKA. We found no differences between VKA and dabigatran in the risk of stroke, haemorrhages or mortality.

Abstract
OBJECTIVES To determine the percentage of female authors in original articles published during 2periods, in the journal of Atención Primaria (Primary Care), and to examine the differences between the categories of authorship (first, last author, and co-author) between both periods. DESIGN Cross-sectional study. SETTING Feminine scientific production published during the periods 2007-2008 and 2017-2018. PARTICIPANTS The study was focused on original articles. MAIN MEASUREMENTS The following variables were collected in an ad hoc form: gender based on the name of the author, total number of women and men appearing as authors, and order of authorship. Absolute and relative authorship frequencies were calculated, and the χ2 test was used to examine the evolution of the percentages by type of authorship and gender. RESULTS A total of 108 articles were analysed in 2007-2008, and 100 in 2017-2018. No statistically significant differences were observed between the mean numbers of women authors within and between periods. In 2007-2008 a total of 548 female authors were identified and 540 in 2017-2018, the percentage of female authors was 48.7% and 54.4%, respectively. Only an increase in the percentage of first authors was observed between periods. CONCLUSIONS Practically one out of every 2authors of original articles published in the journal Atención Primaria was female. There was also a significant increase in the percentage of female first authors between the 2periods. Nevertheless, and despite the greater number of health workers, the number of latest female authors remain unchanged, which points to the persistence of female under-representation.

Abstract
Background Despite their marginal benefit, about 60% of acute lower respiratory tract infections (ALRTIs) are currently treated with antibiotics in Catalonia. This study aims to evaluate the effectiveness and efficiency of a continuous disease-focused intervention (C-reactive protein [CRP]) and an illness-focused intervention (enhancement of communication skills to optimise doctor-patient consultations) on antibiotic prescribing in patients with ALRTIs in Catalan primary care centres. Methods/design A cluster randomised, factorial, controlled trial aimed at including 20 primary care centres (N = 2940 patients) with patients older than 18 years of age presenting for a first consultation with an ALRTI will be included in the study. Primary care centres will be identified on the basis of socioeconomic data and antibiotic consumption. Centres will be randomly assigned according to hierarchical clustering to any of four trial arms: usual care, CRP testing, enhanced communication skills backed up with patient leaflets, or combined interventions. A cost-effectiveness and cost-utility analysis will be performed from the societal and national healthcare system perspectives, and the time horizon of the analysis will be 1 year. Two qualitative studies (pre- and post-clinical trial) aimed to identify the expectations and concerns of patients with ALRTIs and the barriers and facilitators of each intervention arm will be run. Family doctors and nurses assigned to the interventions will participate in a 2-h training workshop before the inception of the trial and will receive a monthly intervention-tailored training module during the year of the trial period. Primary outcomes will be antibiotic use within the first 6 weeks, duration of moderate to severe cough, and the quality-adjusted life-years. Secondary outcomes will be duration of illness and severity of cough measured using a symptom diary, healthcare re-consultations, hospital admissions, and complications. Healthcare costs will be considered and expressed in 2021 euros (year foreseen to finalise the study) of the current year of the analysis. Univariate and multivariate sensitivity analyses will be carried out. Discussion The ISAAC-CAT project will contribute to evaluate the effectiveness and efficiency of different strategies for more appropriate antibiotic prescribing that are currently out of the scope of the actual clinical guidelines.

Abstract
Purpose Validating cases of acute liver injury (ALI) in health care data sources is challenging. Previous validation studies reported low positive predictive values (PPVs). Methods Case validation was undertaken in a study conducted from 2009 to 2014 assessing the risk of ALI in antidepressants users in databases in Spain (EpiChron and SIDIAP) and the Danish National Health Registers. Three ALI definitions were evaluated: primary (specific hospital discharge codes), secondary (specific and nonspecific hospital discharge codes), and tertiary (specific and nonspecific hospital and outpatient codes). The validation included review of patient profiles (EpiChron and SIDIAP) and of clinical data from medical records (EpiChron and Denmark). ALI cases were confirmed when liver enzyme values met a definition by an international working group. Results Overall PPVs (95% CIs) for the study ALI definitions were, for the primary ALI definition, 84% (60%‐97%) (EpiChron), 60% (26%‐88%) (SIDIAP), and 74% (60%‐85%) (Denmark); for the secondary ALI definition, 65% (45%‐81%) (EpiChron), 40% (19%‐64%) (SIDIAP), and 70% (64%‐77%) (Denmark); and for the tertiary ALI definition, 25% (18%‐34%) (EpiChron), 8% (7%‐9%) (SIDIAP), and 47% (42%‐52%) (Denmark). The overall PPVs were higher for specific than for nonspecific codes and for hospital discharge than for outpatient codes. The nonspecific code “unspecified jaundice” had high PPVs in Denmark. Conclusions PPVs obtained apply to patients using antidepressants without preexisting liver disease or ALI risk factors. To maximize validity, studies on ALI should prioritize hospital specific discharge codes and should include hospital codes for unspecified jaundice. Case validation is required when ALI outpatient cases are considered.

Abstract
BACKGROUND The use of metformin in patients with type 2 diabetes mellitus has been associated with lactic acidosis. However, the information available in patients with moderate-severe chronic kidney disease is scarce. METHODS The ALIMAR-C2 study is a case-control study to assess the association between metformin and lactic acidosis in patients with type 2 diabetes mellitus and moderate-severe chronic kidney disease. The study will be performed with computerized registered electronic health records from eight Spanish hospitals linked to their corresponding primary care health areas from 2010 to 2016, comprising approximately 22.1 million person-years of follow-up. Logistic regression will be used to assess the crude and adjusted risk of lactic acidosis associated with metformin use overall and stratifying by use and dose categories, and chronic kidney disease stage. The overall case fatality rate of lactic acidosis, as well as the case fatality rate stratified by chronic kidney disease stage, will be calculated. DISCUSSION The ALIMAR-C2 study will provide useful information about the risk of lactic acidosis in type 2 diabetes mellitus patients with renal impairment using metformin.

Abstract
INTRODUCTION Despite the frequent use of therapies in acute bronchitis, the evidence of their benefit is lacking, since only a few clinical trials have been published, with low sample sizes, poor methodological quality and mainly in children. The objective of this study is to compare the effectiveness of three symptomatic therapies (dextromethorphan, ipratropium or honey) associated with usual care and the usual care in adults with acute bronchitis. METHODS AND ANALYSIS This will be a multicentre, pragmatic, parallel group, open randomised trial. Patients aged 18 or over with uncomplicated acute bronchitis, with cough for less than 3 weeks as the main symptom, scoring ≥4 in either daytime or nocturnal cough on a 7-point Likert scale, will be randomised to one of the following four groups: usual care, dextromethorphan 30 mg three times a day, ipratropium bromide inhaler 20 µg two puffs three times a day or honey 30 mg (a spoonful) three times a day, all taken for up to 14 days. The exclusion criteria will be pneumonia, criteria for hospital admission, pregnancy or lactation, concomitant pulmonary disease, associated significant comorbidity, allergy, intolerance or contraindication to any of the study drugs or admitted to a long-term residence. SAMPLE 668 patients. The primary outcome will be the number of days with moderate-to-severe cough. All patients will be given a paper-based symptom diary to be self-administered. A second visit will be scheduled at day 2 or 3 for assessing evolution, with two more visits at days 15 and 29 for clinical assessment, evaluation of adverse effects, re-attendance and complications. Patients still with symptoms at day 29 will be called 6 weeks after the baseline visit. ETHICS AND DISSEMINATION The study has been approved by the Ethical Board of IDIAP Jordi Gol (reference number: AC18/002). The findings of this trial will be disseminated through research conferences and peer-review journals. TRIAL REGISTRATION NUMBER NCT03738917; Pre-results.

Antidepressant use in Denmark, Germany, Spain, and Sweden between 2009 and 2014: Incidence and comorbidities of antidepressant initiators. J Affect Disord 2019; 249:242-252. [PMID: 30780117 DOI: 10.1016/j.jad.2019.02.010] [Citation(s) in RCA: 38] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2018] [Revised: 01/18/2019] [Accepted: 02/05/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND We aimed to describe patterns of use and characteristics of 10 commonly used antidepressants for the period 2009-2014 in Denmark, Germany, Spain, and Sweden. METHODS Adult initiators from 2009 to 2014 of each study antidepressant were identified in four countries using five data sources: the Danish National registers, GePaRD (Germany), EpiChron (Aragon, Spain), SIDIAP (Catalonia, Spain), and the Swedish National Registers. The study included 10 study antidepressants: citalopram, escitalopram, fluoxetine, paroxetine, sertraline, duloxetine, venlafaxine, amitriptyline, mirtazapine, and agomelatine. RESULTS Citalopram was the most prescribed study antidepressant, followed by mirtazapine. Paroxetine and agomelatine were the least prescribed antidepressants. Mirtazapine was widely used among older antidepressant initiators with higher percentages of comorbidities at baseline, and fluoxetine was used among young patients. Citalopram and amitriptyline had the lowest percentage of multiple antidepressant use in the 12 months prior to the current treatment episode, while agomelatine, duloxetine, and venlafaxine had the highest percentage of multiple antidepressant use in the year prior to the current treatment episode. LIMITATIONS The most important limitations are exposure information based on filled prescriptions, focus on antidepressant initiators only, lack of information on the indication, and heterogeneity of the type of data across data sources. CONCLUSIONS Results of this study including 4.8 million study antidepressant initiators of study antidepressants suggest that citalopram and mirtazapine are the most commonly prescribed antidepressants. Agomelatine and paroxetine were the least used antidepressants in the participating populations. Mirtazapine was the antidepressant most commonly prescribed among older antidepressant initiators with high percentage of comorbidities at baseline, whereas fluoxetine was commonly used among young patients.

Abstract
BACKGROUND Agomelatine is a melatonin receptor agonist and serotonin 5-HT2C receptor antagonist indicated for depression in adults. Hepatotoxic reactions like acute liver injury (ALI) are an identified risk in the European risk management plan for agomelatine. Hepatotoxic reactions have been reported for other antidepressants, but population studies quantifying these risks are scarce. Antidepressants are widely prescribed, and users often have risk factors for ALI (e.g. metabolic syndrome). OBJECTIVE The goal was to estimate the risk of ALI associated with agomelatine and other antidepressants (fluoxetine, paroxetine, sertraline, escitalopram, mirtazapine, venlafaxine, duloxetine, and amitriptyline) when compared with citalopram in routine clinical practice. METHOD A nested case-control study was conducted using data sources in Denmark, Germany, Spain, and Sweden (study period 2009-2014). Three ALI endpoints were defined using International Classification of Diseases (ICD) codes: primary (specific codes) and secondary (all codes) endpoints used only hospital discharge codes; the tertiary endpoint included both inpatient and outpatient settings (all codes). Validation of endpoints was implemented. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for current use were estimated for each data source and combined. RESULTS We evaluated 3,238,495 new antidepressant and 74,440 agomelatine users. For the primary endpoint, the OR for agomelatine versus citalopram was 0.48 (CI 0.13-1.71). Results were also < 1 when no exclusion criteria were applied (OR 0.37; CI 0.19-0.74), when all exclusion criteria except alcohol and drug abuse were applied (OR 0.47; CI 0.20-1.07), and for the secondary (OR 0.40; CI 0.05-3.11) and tertiary (OR 0.79; CI 0.50-1.25) endpoints. Regarding other antidepressants versus citalopram, most OR point estimates were also below one, although with varying widths of the 95% CIs. The result of the tertiary endpoint and the sensitivity analyses of the primary endpoint were the most precise. CONCLUSION In this study, using citalopram as a comparator, agomelatine was not associated with an increased risk of ALI hospitalisation. The results for agomelatine should be interpreted in the context of the European risk minimisation measures in place. Those measures may have induced selective prescribing and could explain the lower risk of ALI for agomelatine when compared with citalopram. Most other antidepressants evaluated had ORs suggesting a lower risk than citalopram, but additional studies are required to confirm or refute these results.

Abstract
Introduction: Our objective was to assess efficacy, safety and tolerance of topical potassium hydroxide (KOH) 10% for treating Molluscum contagiosum (MC) in children. Material and methods: Randomized, double-blind, placebo-controlled clinical trial including all children 2-16 years with MC infection attending pediatrician primary healthcare visits. The treatment was KOH 10% gel applied once daily up to clearing (maximum 30 days). Results: KOH 10% showed superior efficacy to placebo (55.3% vs 16.3%, p < .001). Time until clearing was inferior with KOH 10% (p = .001). MC lesions were reduced with KOH 10%, which also showed higher efficacy when the instructions of use of the device were modified. KOH 10% patients presented more adverse events (AE) than placebo patients (72.3% vs 31.8%, p < .001). Most patients (91.5%) completely recovered. There were no differences in frequency of AE before and after the change of instructions, intolerance was more frequently reported by parents with new instructions. Conclusions: KOH 10% was superior to placebo in the main efficacy outcome and most secondary efficacy outcomes. KOH 10% patients had more AE and intolerance symptoms than placebo, although there were no severe AE and most patients recovered. KOH 10% is an effective and safe topical treatment for MC infection in children.

Abstract
BACKGROUND To assess uncertainty in regulatory decision-making for orphan medicinal products (OMP), a summary of the current basis for approval is required; a systematic grouping of medical conditions may be useful in summarizing information and issuing recommendations for practice. METHODS A grouping of medical conditions with similar characteristics regarding the potential applicability of methods and designs was created using a consensus approach. The 125 dossiers for authorised OMP published between 1999 and 2014 on the EMA webpage were grouped accordingly and data was extracted from European Public Assessment Reports (EPARs) to assess the extent and robustness of the pivotal evidence supporting regulatory decisions. RESULTS 88% (110/125) of OMP authorizations were based on clinical trials, with 35% (38/110) including replicated pivotal trials. The mean (SD) number of pivotal trials per indication was 1.4 (0.7), and the EPARs included a median of three additional non-pivotal supportive studies. 10% of OMPs (13/125) were authorised despite only negative pivotal trials. One-third of trials (53/159) did not include a control arm, one-third (50/159) did not use randomisation, half the trials (75/159) were open-label and 75% (119/159) used intermediate or surrogate variables as the main outcome. Chronic progressive conditions led by multiple system/organs, conditions with single acute episodes and progressive conditions led by one organ/system were the groups where the evidence deviated most from conventional standards. Conditions with recurrent acute episodes had the most robust datasets. The overall size of the exposed population at the time of authorisation of OMP - mean(SD) 190.5 (202.5) - was lower than that required for the qualification of clinically-relevant adverse reactions. CONCLUSIONS The regulatory evidence supporting OMP authorization showed substantial uncertainties, including weak protection against errors, substantial use of designs unsuited for conclusions on causality, use of intermediate variables, lack of a priorism and insufficient safety data to quantify risks of relevant magnitude. Grouping medical conditions based on clinical features and their methodological requirements may facilitate specific methodological and regulatory recommendations for the study of OMP to strengthen the evidence base.

Abstract
Atrial fibrillation (AF) is the most common chronic arrhythmia, with increasing healthcare and economic burden and a prevalence which increases with progressive ageing. This study aims to describe overall annual costs per patient for management of non-valvular AF in a primary healthcare (PHC) setting and compare these costs between the groups of patients treated with vitamin K antagonists, antiplatelets or non-treated through a population-based study conducted with electronic health records. We analysed annual costs per person of 19,787 patients in 2012; PHC visits, hospital admissions, AF-related events requiring hospital admission, referrals to secondary specialists, sick leave, diagnostic tests and laboratory tests at PHC level, including INR determinations performed in PHC, and drug therapy. Higher costs of AF management were associated with increasing age, male sex, stroke and bleeding risks, comorbidities and occurrence of events associated to AF. The sensitivity analyses conducted showed that PHC visits and hospitalizations represented the most important part of overall costs for all patients.

Abstract
BACKGROUND In 2010, a safety signal was detected for narcolepsy following vaccination with Pandemrix, an AS03-adjuvanted monovalent pandemic H1N1 influenza (pH1N1) vaccine. To further assess a possible association and inform policy on future use of adjuvants, we conducted a multi-country study of narcolepsy and adjuvanted pH1N1 vaccines. METHODS We used electronic health databases to conduct a dynamic retrospective cohort study to assess narcolepsy incidence rates (IR) before and during pH1N1 virus circulation, and after pH1N1 vaccination campaigns in Canada, Denmark, Spain, Sweden, Taiwan, the Netherlands, and the United Kingdom. Using a case-control study design, we evaluated the risk of narcolepsy following AS03- and MF59-adjuvanted pH1N1 vaccines in Argentina, Canada, Spain, Switzerland, Taiwan, and the Netherlands. In the Netherlands, we also conducted a case-coverage study in children born between 2004 and 2009. RESULTS No changes in narcolepsy IRs were observed in any periods in single study sites except Sweden and Taiwan; in Taiwan incidence increased after wild-type pH1N1 virus circulation and in Sweden (a previously identified signaling country), incidence increased after the start of pH1N1 vaccination. No association was observed for Arepanrix-AS03 or Focetria-MF59 adjuvanted pH1N1 vaccines and narcolepsy in children or adults in the case-control study nor for children born between 2004 and 2009 in the Netherlands case-coverage study for Pandemrix-AS03. CONCLUSIONS Other than elevated narcolepsy IRs in the period after vaccination campaigns in Sweden, we did not find an association between AS03- or MF59-adjuvanted pH1N1 vaccines and narcolepsy in children or adults in the sites studied, although power to evaluate the AS03-adjuvanted Pandemrix brand vaccine was limited in our study.

Abstract
BACKGROUND Apixaban is a direct oral anticoagulant, which inhibits factor Xa. It has demonstrated clinical efficacy in prevention of stroke and systemic embolism in adult patients with nonvalvular atrial fibrillation and a better safety profile compared to warfarin. OBJECTIVES (1) To describe the characteristics of patients with nonvalvular atrial fibrillation beginning treatment with apixaban, (2) to analyze concomitant prescriptions of medications that could potentially interact with apixaban, (3) to evaluate the level of appropriate usage according to the recommended dosage, and (4) to estimate the level of apixaban persistence among naive and non-naive patients. METHODS Cohort study using data from primary care (System for Research in Primary Care database, users of the Institut Català de la Salut; Catalonia, Spain) from August 2013 to December 2015. RESULTS Mean age for apixaban-treated patients was 71.8 years (standard deviation = 11.1) and 55.6% were male. In all, 3.2% of patients receiving apixaban were taking drugs described as potentially related to either pharmacokinetic or pharmacodynamic interactions. According to the summary of product characteristics, 81.1% of patients with a recommended dose of 2.5 mg twice daily and 51.8% with a recommended dose of 5 mg twice daily actually took this dose. After 1 year of follow-up, 62.6% of the apixaban users showed good adherence. CONCLUSION The prescribed dose of apixaban did not fully follow the recommended dose, particularly in patients who were treatment naive. Patients with a prior history of anticoagulant treatment were more likely to remain persistent to treatment with apixaban.

Abstract
BACKGROUND Cilostazol has been associated with spontaneous reports of cardiovascular adverse events and serious bleeding. The objective of this study is to determine the relative risk of cardiovascular adverse events or haemorrhages in patients with peripheral artery disease treated with cilostazol in comparison to pentoxifylline users. METHODS Population-based cohort study including all individuals older than 40 who initiated cilostazol or pentoxifylline during 2009-2011 in SIDIAP database. The two treatment groups were matched through propensity score (PS). RESULTS Nine thousand one hundred twenty-nine patients met inclusion criteria and after PS matching, there were 2905 patients in each group. 76% of patients were men, with similar mean ages in both groups (68.8 for cilostazol and 69.4 for pentoxifylline). There were no differences in bleeding, cerebrovascular and cardiovascular events between both groups. CONCLUSIONS Patients treated with cilostazol were different from those treated with pentoxifylline at baseline, so they were matched through PS. We did not find differences between treatment groups in the incidence of bleeding or cardiovascular and cerebrovascular events. Cilostazol should be used with precaution in elderly polymedicated patients.

Abstract
BACKGROUND/OBJECTIVES Molluscum contagiosum is the most common skin infection in children. One topical treatment used for Molluscum contagiosum is potassium hydroxide. The objective of this study was to compare the efficacy of potassium hydroxide topical treatment at different concentrations with that of placebo in terms of complete clearing of Molluscum contagiosum lesions and to assess the safety and tolerance of potassium hydroxide topical treatment. METHODS This was a double-blind randomized clinical trial of three treatments (potassium hydroxide 10%, potassium hydroxide 15%, placebo) applied once daily up to complete clearing of lesions (maximum duration 60 days) in 53 children aged 2-6 years in primary health care pediatric offices in Catalonia, Spain. RESULTS In the intention-to-treat analysis, potassium hydroxide 10% (58.8%, P = .03) and potassium hydroxide 15% (64.3%, P = .02) had efficacy superior to that of placebo (18.8%). The number of Molluscum contagiosum lesions was significantly reduced with potassium hydroxide 10% and 15%. The main efficacy outcome was achieved in 58.8% of children in the potassium hydroxide 10% group (P = .03 vs placebo) and in 64.3% of children in the potassium hydroxide 15% group (P = .02 vs placebo). Potassium hydroxide 10% and 15% were not significantly different in efficacy from each other. Potassium hydroxide 10% and placebo were better tolerated than potassium hydroxide 15%. No adverse events were reported during the study period. CONCLUSIONS Potassium hydroxide 10% and 15% demonstrated high rates of efficacy in clearing Molluscum contagiosum lesions, with potassium hydroxide 10% being better tolerated.

Abstract
BACKGROUND Cardiovascular disease (CVD) is a group of disorders of the heart and blood vessels, such as coronary heart disease (CHD), cerebrovascular disease, and peripheral artery disease. CVD is the leading threat to global health, whether measured by mortality, morbidity, or economic cost. Long-term administration of aspirin, statins, beta-blockers, and angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers improves survival in patients with stablished coronary heart disease. Nevertheless, adherence to prescribed medication is poor for long-term drug treatment. OBJECTIVE We aim to assess the relationship between adherences to the four pharmacological groups recommended for secondary prevention and the clinical outcomes of cardiovascular morbidity and mortality in patients with established CHD according to the level of adherence to these drugs in a population of incident cases of acute coronary syndrome (ACS). METHODS Population-based cohort study of patients with a first episode of ACS during 2006-2015 in the Information System for Research in Primary Care (SIDIAP) database. We will estimate adherence to these drugs. The primary endpoint is a composite of all-cause mortality, ACS, and ischaemic stroke. Bivariate analyses will be performed estimating odds ratios for categorical variables and mean differences for continuous variables. Hazard ratios for adherences will be calculated for outcome events using Cox proportional hazard regression models, and proportionality of hazards assumption will be tested. RESULTS We expect to estimate adherence to all four study treatments, the incidence of MACE, and to analyze if this incidence is associated with the level of drug adherence. CONCLUSIONS We expect to find that adherent patients have a lower risk of the primary endpoints compared with nonadherent patients. TRIAL REGISTRATION This study protocol was classified as EPA-OD by the AEMPS (IJG-EST-2017-01-2017-01, 07/04/2017) and registered in the EU PAS register (EUPAS19017, 09/05/2017).

Abstract
PURPOSE Recent controversies on the safety profiles of opioids and paracetamol (acetaminophen) have led to changes in clinical guidance on osteoarthritis (OA) management. We studied the existing association between the use of different OA drug therapies and the risk for acute coronary events. METHODS A cohort of patients with clinically diagnosed OA (according to ICD-10 codes) was identified in the SIDIAP database. Within the cohort, cases with incident acute coronary events (acute myocardial infarction or unstable angina) between 2008 and 2012 were identified using ICD-10 codes and data from hospital admission. Controls were matched 3:1 to acute coronary event-free patients matched by sex, age (±5 years), geographic area, and years since OA diagnosis (±2 years). Linked pharmacy dispensation data were used for assessing exposure to drug therapies. Multivariate conditional logistic regression models were fitted to estimate adjusted odds ratios of acute coronary events. FINDINGS Totals of 5663 cases and 16,989 controls were studied. Previous morbidity and cardiovascular risk were higher in cases than in controls, with no significant differences in type or number of joints with OA. Multivariate adjusted analyses showed increased risks (odds ratio; 95% CI) related to the use of diclofenac (1.16; 1.06-1.27), naproxen (1.25; 1.04-1.48), and opioid analgesics (1.13; 1.03-1.24). No significant associations were observed with cyclooxygenase-2 selective NSAIDs, topical NSAIDs, glucosamine, chondroitin sulfate, paracetamol, or metamizole. IMPLICATIONS In patients with clinically diagnosed OA, the use of nonselective NSAIDs or opioid analgesics is associated with an increased risk for acute coronary events. These risks should be considered when selecting treatments of OA in patients at high cardiovascular risk.
