RESUMEN
Background: Despite global concerns of an opioid epidemic, there is no systematic literature review on how frequently these drugs are used in nursing home (NH) populations, including those living with dementia. Objective: This systematic review aims to describe the prevalence and incidence of opioid use in NHs. A secondary objective is to describe the use of these drugs in a subset of NH residents, namely among persons living with dementia. Methods: A systematic literature review was carried out using MEDLINE and Scopus (PROSPERO registration number CRD42021254210). Screening of title and abstract was carried out by 2 persons independently for studies published between January 1, 2011 and May 19, 2021. The main outcomes were annual prevalence, period prevalence, and duration of opioid use. Results: From a total of 178 identified studies, 29 were considered eligible for inclusion. The annual prevalence of any opioid use among all NH residents without any selection criteria ranged from 6.3% to 50% with a median annual prevalence of 22.9% (Q25-Q75: 19.5%-30.2%), based on 17 studies. Five studies measured the annual prevalence in NH residents living with dementia, finding that this ranged from 10% to 39.6%. Conclusions: More evidence is needed quantifying opioid use in NH, especially among persons living with dementia. Given that opioid use in NH is still a problem, implementation of a pain management protocol in NH or nationally would help improve clinical outcomes.
RESUMEN
Nivolumab is used to treat several different types of cancers. Although it is generally considered to be effective and well-tolerated, it has been associated with adverse effects requiring discontinuation of treatment, like many other drugs used for cancer. A 70-year-old male was switched from sunitinib to nivolumab for renal cell carcinoma. The patient developed persistent hypothyroidism, onycholysis, and pneumonitis at nivolumab cycle 6, 10, and 11, respectively. Using the Naranjo causality method, the likelihood of causality was deemed "probable" for pneumonitis and hypothyroidism and "possible" for onycholysis. Nivolumab was eventually discontinued due to disease progression, rather than safety concerns. Eudravigilance, the European pharmacovigilance database, was searched for all nivolumab-related individual case safety reports from Malta, up to September 4, 2023. Six reports were identified in Malta, although the 3 events identified in this case report were not reported, suggesting under-reporting in Malta. This case report identified an uncommon nivolumab adverse drug reaction (ADR), onycholysis and showed how, despite the occurrence of 3 ADRs, it was its lack of efficacy rather than its safety which led to its discontinuation in this particular patient.
RESUMEN
To date, there is no published overview of the drug pipeline in granulomatosis with polyangiitis (GPA), a rare disease. The aim of this study was to identify clinical trials from two study repositories. A review of clinical trials was conducted using publicly available data. Clinicaltrials.gov and International Clinical Trials Registry Platform were searched from inception until 25 September 2022. Only GPA-specific studies were included; these were described in detail. A total of 137 studies were identified in the trial repositories, of which 108 (79%) studies were found to concern GPA. Of these 108 studies, 67 enrolled GPA patients to investigate pharmacotherapy in this disease (62%). Most studies included all severity types (n = 51; 76%); the scope of almost half of the studies was remission induction (n = 33; 49%). The drug class which was by the most widely investigated in trials was the non-corticosteroid immunosuppressant drug class (46; 68.7%), monoclonal antibodies (32; 47.8%), and corticosteroids (31; 46.3%). There is a need for more GPA trials to generate evidence on effectiveness in terms of severity-specificity and maintenance of remission.
The pharmacological treatment of granulomatosis with polyangiitis: a review of clinical trials To date, there is no published overview of the drug pipeline in granulomatosis with polyangiitis (referred to in this paper as GPA), a rare disease. The aim of this study was to identify such studies from two study archives. Clinicaltrials.gov and International Clinical Trials Registry Platform (ICTRP) were searched from inception until 25th September 2022. Studies recruiting GPA patients were included; these were described in detail. A total of 137 studies were identified in the trial repositories, of which 108 were found to concern GPA. Of these 108 studies, 67 enrolled GPA patients to investigate the treatment of this disease through the administration of drugs. Most studies included all severity types (n = 51); the scope of almost half of the studies was to induce remission (n = 33). The drug classes which were the most widely investigated in trials were non-corticosteroid immunosuppressant drugs (n = 46), monoclonal antibodies (n = 32), and corticosteroids (n = 31). There is a need for more GPA clinical trials to generate evidence on effectiveness of drugs in terms of severity-specificity and maintenance of remission.
RESUMEN
INTRODUCTION: During the signal detection process, statistical methods are used to identify drug-event combinations (DECs) which are disproportionately reported when compared with other drugs and events in the entire database. We hypothesise that the high volume of COVID-19 vaccine adverse drug reaction (ADR) reports transmitted to EudraVigilance may have affected the performance of disproportionality statistics used in routine signal detection, potentially resulting in signals either being masked, or false associations being flagged as potential signals. OBJECTIVE: Our aim was to study the impact of COVID-19 vaccine spontaneous reporting on statistical signal detection in EudraVigilance. METHODS: We recalculated the reporting odds ratio (ROR) for signals that were previously discussed at the level of the Pharmacovigilance Risk Assessment Committee, or signals that were retrieved from EudraVigilance, by omitting COVID-19 vaccine reports from the standard ROR calculation and then comparing the lower confidence interval (LCI) of the recalculated ROR to the LCI of the actual ROR in EudraVigilance. RESULTS: In total, 52 signals for 38 active substances were reviewed. For 35 signals, the LCI of the recalculated ROR value was lower than the LCI of the actual ROR (suggesting that COVID-19 vaccine ADR reporting had a positive effect on the strength of the signal) while for 15 signals the LCI of the recalculated ROR value was higher than the LCI of the actual ROR (suggesting that COVID-19 vaccine ADR reporting had an attenuating effect on the strength of the signal). For two signals, no change in the ROR was observed. In our analysis, six significant results were found. Five DECs were found to be masked: bleomycin and immune thrombocytopenia (actual ROR LCI = 0.94, recalculated ROR LCI = 1.02), vortioxetine and heavy menstrual bleeding (actual ROR LCI = 0.3, recalculated ROR LCI = 1.06), caplacizumab and heavy menstrual bleeding (actual ROR LCI = 0.98, recalculated ROR LCI = 3.47), ziprasidone and amenorrhoea (actual ROR LCI = 0.84, recalculated ROR LCI = 1.67), and azacitidine and pericarditis (actual ROR LCI = 0.81, recalculated ROR LCI = 2.01). For the DEC of adalimumab and immune reconstitution inflammatory syndrome, the LCI of the actual ROR value was 1.14 and removing COVID-19 vaccine reporting resulted in an LCI of the recalculated ROR value of 0.94 (below threshold). CONCLUSIONS: We demonstrated five cases of masking and one case of false-positive association due to the influence of COVID-19 vaccine spontaneous reporting on the ROR. This suggests that the high number of adverse drug reaction reports for COVID-19 vaccines in EudraVigilance has the potential to affect routine statistical signal detection activities. The impact of COVID-19 vaccine ADR reports on current signal detection practices requires further evaluation and solutions to tackle masking issues in EudraVigilance may need to be developed.

INTRODUCTION: Prescription and drug order writing are key components of patient care allowing physicians communicate their therapeutic plans. Although electronic prescriptions are becoming more common, handwritten prescriptions are still quite prevalent and a persistent issue with handwritten prescriptions is the illegibility of physician handwritings. Prescriptions have to be legible to avoid delays in healthcare provision and consequences as serious as patient death. AREAS COVERED: We did a scoping review of multiple articles that assessed the legibility of prescriptions in different settings (inpatient, outpatient, and pharmacies) and countries, ranging from 1997 to 2020. Studies also elaborated on possible reasons for these suboptimal prescriptions and ways to address them. EXPERT OPINION: While the degree of legibility of prescriptions varies widely, it remains a concern because a single incorrectly read prescription can have severe consequences. Various measures exist to possibly minimize illegible prescriptions and while none alone is probably sufficient, combining is likely to yield great results. One is the sensitization and education of physicians and physicians-in-training. Another option is audits and a third and very potent option is the use of computerized provider order entry (CPOE) system which will help improve patient safety by reducing errors due to inappropriately read prescriptions.

INTRODUCTION: Migraine is common in females of childbearing age and negatively impacts quality of life. The majority of those with migraine who become pregnant see an improvement in their condition but not all do. Providing evidence-based recommendations for the pharmacological management of migraine in pregnancy is challenging. AREAS COVERED: This narrative review provides an update on the safety of drugs used for migraine in pregnancy. National and international guidelines on the management of episodic migraine in adults were used to select the drugs of relevance to pregnant women. The final list of drugs was chosen by a pain specialist who categorized them according to drug class and use in acute management or prevention. PubMed was searched from inception to 31st July 2022 for evidence on drug safety. EXPERT OPINION: Obtaining high-quality drug safety data in pregnant migraineurs is difficult not least because exposing a fetus to research-related risks is often considered unethical. There is reliance on observational studies which often group drugs together and lack specificities pertinent to drug prescribing like timing, dosing and duration. Improved statistical tools, study designs and the creation of international collaborative frameworks are ways to advance knowledge on drug safety in pregnancy.

BACKGROUND: Medication error is a common cause of patient harm. The study aims to propose a way to manage the risk of medication errors in a novel way, by identifying practice areas where mitigating patient harm should be prioritized using a risk management approach. METHODS: Suspected Adverse Drug Reactions (sADRs) in Eudravigilance database over three years were reviewed to identify preventable medication errors. These were classified using a new method based upon the root cause underlying pharmacotherapeutic failure. The correlation between severity of harm and type of medication error, and other clinical parameters was investigated. RESULTS: Overall, 2294 medication errors were identified from Eudravigilance, of which 1300 (57%) were due to pharmacotherapeutic failure. Most cases of preventable medication error involved prescribing (41%) and administration (39%). The variables which significantly predicted severity of medication errors were pharmacological group, patient age, number of drugs prescribed, and route of administration. The drug classes most strongly associated with harm included cardiac drugs, opioids, hypoglycaemics, antipsychotics, sedatives, and antithrombotic agents. CONCLUSION: The findings of this study highlight the feasibility of using a novel conceptual framework to identify areas of practice at risk of pharmacotherapeutic failure where Interventions by healthcare professionals in these areas are most likely to improve medication safety.

Drug repositioning and repurposing has proved useful in identifying new treatments for many diseases, which can then rapidly be brought into clinical practice. Currently, there are few effective pharmacological treatments for Lewy body dementia (which includes both dementia with Lewy bodies and Parkinson's disease dementia) apart from cholinesterase inhibitors. We reviewed several promising compounds that might potentially be disease-modifying agents for Lewy body dementia and then undertook an International Delphi consensus study to prioritise compounds. We identified ambroxol as the top ranked agent for repurposing and identified a further six agents from the classes of tyrosine kinase inhibitors, GLP-1 receptor agonists, and angiotensin receptor blockers that were rated by the majority of our expert panel as justifying a clinical trial. It would now be timely to take forward all these compounds to Phase II or III clinical trials in Lewy body dementia.

RESUMEN
INTRODUCTION: Transforming growth factor beta induced (TGFBI) gene mutations have been reported as the cause of a group of genetically inherited, visually debilitating, corneal dystrophies (CD). A scoping literature review to identify and categorize compounds that inhibit corneal TGFBI expression and/or promote TGFBIp degradation was performed. Emphasis was given to their potential to be used as a cost-effective approach via drug repurposing. AREAS COVERED: We performed a thorough search of original peer-reviewed literature using electronic bibliographic databases and selected articles according to a set of criteria. The total number of articles retrieved from the search terms applied to the databases was 2344. The number of relevant full-text articles included added up to 19. We identified 16 compounds that can theoretically reduce the levels of mutant TGFBIp in human corneal cells. EXPERT OPINION: Currently, the only temporary treatments available for this condition are lubricant drops and surgery. Here, we explored the crosstalk between cascades that regulate TGFBI expression and identified compounds that target these pathways. Compounds that inhibit DNA synthesis and function, increase elimination of TGFBIp or bind to mutant TGFBIp were also explored with the aim of highlighting promising compounds that can be used in future cost-effective drug-repurposing studies.

Acromegaly is a rare disease characterized by an excessive production of growth-hormone and insulin-like growth factor 1, typically resulting from a GH-secreting pituitary adenoma. This study was aimed at comparing and measuring accuracy of newly and previously developed coding algorithms for the identification of acromegaly using Italian claims databases. This study was conducted between January 2015 and December 2018, using data from the claims databases of Caserta Local Health Unit (LHU) and Sicily Region in Southern Italy. To detect acromegaly cases from the general target population, four algorithms were developed using combinations of diagnostic, surgical procedure and co-payment exemption codes, pharmacy claims and specialist's visits. Algorithm accuracy was assessed by measuring the Youden Index, sensitivity, specificity, positive and negative predictive values. The percentage of positive cases for each algorithm ranged from 7.9 (95% CI 6.4-9.8) to 13.8 (95% CI 11.7-16.2) per 100,000 inhabitants in Caserta LHU and from 7.8 (95% CI 7.1-8.6) to 16.4 (95% CI 15.3-17.5) in Sicily Region. Sensitivity of the different algorithms ranged from 71.1% (95% CI 54.1-84.6%) to 84.2% (95% CI 68.8-94.0%), while specificity was always higher than 99.9%. The algorithm based on the presence of claims suggestive of acromegaly in ≥ 2 different databases (i.e., hospital discharge records, copayment exemptions registry, pharmacy claims and specialist visits registry) achieved the highest Youden Index (84.2) and the highest positive predictive value (34.8; 95% CI 28.6-41.6). We tested four algorithms to identify acromegaly cases using claims databases with high sensitivity and Youden Index. Despite identifying rare diseases using real-world data is challenging, this study showed that robust validity testing may yield the identification of accurate coding algorithms.

INTRODUCTION: This study aimed to establish which worldwide population cohorts have a genetic make-up closest to that of a large sample of the Maltese population with regard to corneal dystrophy (CD) genes. METHODS: Single nucleotide polymorphisms (SNPs) in the Maltese cohort were compared with worldwide cohorts. Fixation index (FST) values were calculated to evaluate population differentiation. The genetic prevalence of CD subtypes in worldwide and Maltese cohorts were calculated, and single nucleotide missense mutations present in the Maltese cohort were evaluated for potential pathogenicity. RESULTS: FST values showed that CD-related genes differ substantially among the studied cohorts. FST values for each SNP showed greatest differentiation between the Maltese and African cohorts and least differentiation with the Puerto Rican, Mexican, and Colombian cohorts. One TGFBI casual CD mutation, 502V, which causes a Bowman's layer CD/atypical Thiel-Behnke CD was identified in the Maltese cohort. The KRT3 NC_000012.11:g.53186088G>C mutation was potentially deleterious. CONCLUSION: Identifying populations with least genetic differentiation can facilitate and help guide future diagnostic and treatment strategies for Maltese individuals with CDs in the absence of comparable Maltese data. Analysing the previously unknown CD genetic pool present in a large Maltese cohort adds to the global genetic bank that researchers rely on for medical progress.

Describe drug utilisation and clinical outcomes of intravitreal anti-VEGF drug and dexamethasone use in the real-world setting in Southern Italy using data from multi-centre study of retinal disease. Clinical data of retinal disease patients treated with anti-VEGF drugs and dexamethasone implant in 6 out-patient ophthalmology centres from Southern Italy were collected by means of an electronic case report form. Patients receiving at least one intravitreal injection/implant of the study drugs were followed for up to two years and described in terms of demographics and clinical characteristics. Drug utilisation patterns were described. A sign-rank test was used to compare clinical data on visual acuity and other ophthalmic parameters from baseline at different follow-up times for each indication. Data from 1327 patients was collected. Most patients were diagnosed with age-related macular degeneration (AMD) (660, 49.7%), followed by diabetic macular oedema (423, 31.9%), retinal vein occlusion (164, 12.3%), and myopic choroidal neovascularization (80, 6.0%). Patients were followed for a median of 10.3 months (interquartile range: 3.6 - 24.7 months). Mean patient age was 69.7 (±10.9) years and 54.2% were males. Ranibizumab (55.4%) and aflibercept (27.5%) were the most commonly used drugs. Baseline visual acuity significantly improved by about 0.05 to 0.1 logMAR at all follow-up times for AMD and RVO but less consistently for the other diseases. Intravitreal ranibizumab use accounted for half of all treatment for retinal diseases in a Southern Italian out-patient setting. Patients treated with anti-VEGF drugs for AMD and RVO in Southern Italy experienced significant improvement in VA.

BACKGROUND: The European post-authorisation study (EU PAS) register is a repository launched in 2010 by the European Medicines Agency (EMA). All EMA-requested PAS, commonly observational studies, must be recorded in this register. Multi-database studies (MDS) leveraging secondary data have become an important strategy to conduct PAS in recent years, as reflected by the type of studies registered in the EU PAS register. OBJECTIVES: To analyse and describe PAS in the EU PAS register, with focus on MDS. METHODS: Studies in the EU PAS register from inception to 31st December 2018 were described concerning transparency, regulatory obligations, scope, study type (e.g., observational study, clinical trial, survey, systematic review/meta-analysis), study design, type of data collection and target population. MDS were defined as studies conducted through secondary use of >1 data source not linked at patient-level. Data extraction was carried out independently by 14 centres with expertise in pharmacoepidemiology, using publicly available information in the EU PAS register including study protocol, whenever available, using a standardised data collection form. For validation purposes, a second revision of key fields for a 15% random sample of studies was carried out by a different centre. The inter-rater reliability (IRR) was then calculated. Finally, to identify predictors of primary data collection-based studies/versus those based on secondary use of healthcare databases) or MDS (vs. non-MDS), odds ratios (OR) and 95% confidence intervals (CI) were calculated fitting univariate logistic regression models. RESULTS: Overall, 1426 studies were identified. Clinical trials (N = 30; 2%), systematic reviews/meta-analyses (N = 16; 1%) and miscellaneous study designs (N = 46; 3%) were much less common than observational studies (N = 1227; 86%). The protocol was available for 63% (N = 360) of 572 observational studies requested by a competent authority. Overall, 36% (N = 446) of observational studies were based fully or partially on primary data collection. Of 757 observational studies based on secondary use of data alone, 282 (37%) were MDS. Drug utilisation was significantly more common as a study scope in MDS compared to non-MDS studies. The overall percentage agreement among collaborating centres that collected the data concerning study variables was highest for study type (93.5%) and lowest for type of secondary data (67.8%). CONCLUSIONS: Observational studies were the most common type of studies in the EU PAS register, but 30% used primary data, which is more resource-intensive. Almost half of observational studies using secondary data were MDS. Data recording in the EU PAS register may be improved further, including more widespread availability of study protocols to improve transparency.

INTRODUCTION: It is generally acknowledged that the ocular safety profile of intravitreal anti-VEGF drugs is acceptable, while the burden of systemic safety of these intravitreal agents is still being debated. The evaluation of the systemic safety of these drugs using real-world data (RWD), such as spontaneous reporting systems (SRS), electronic medical records (EMRs) and claims databases has several advantages, including the capture of outcomes among real-world populations over long observation periods. Nevertheless, there is a relatively small body of research exploring the post-marketing safety of these drugs. AREAS COVERED: The aim of this scoping review is to outline and discuss some of the methodological challenges to be faced when investigating the systemic safety of intravitreal anti-VEGF drugs using different sources of RWD. EXPERT OPINION: Such challenges include the selection of the most suitable data source, taking into account how well drug utilization is captured and whether the outcomes and covariates of interest can be captured. The strengths and limitations of some analytic methods that can be used to quantify risk, such as the intention-to-treat approach and the as-treated approach, complement each other, and using these together provides a more balanced analysis.
