However, it is unknown whether there has been an increase in clinical research evaluating the risks associated with contrast media usage, especially regarding contrast-induced nephropathy. To fill this gap in knowledge, we performed a systematic review.Study eligibility criteria: Meta-analyses, observational studies, and clinical trials assessing contrast media-induced nephropathy as the safety outcome, in which at least one author was affiliated with an Italian university/health care structure, were eligble.Data sources: Ovid MEDLINE, Ovid Embase, Cochrane Methodology Register, and Web of Science were screened.Participants: Men and women exposed to contrast media.Results: In total, 60 original articles were retrieved with an incremental trend between 1990 and 2017. Cohort studies were the most common study design represented. In total, 45 of 60 (75.0%) studies were monocenter studies and 41 of 60 (68.3%) received no funding. In all, 91.7% of studies disclosed no conflicts of interest and 81.7% had no external collaboration. Most of thestudies provided a level of evidence of III-2 (32/60; 53.3%) and II (23/60; 38.3%). In total, 50of 60 studies (83.3%) were published in a scientific journal ranked in the first quartile of their subject area.Conclusion: There was an increased number of studies evaluating contrast-induced nephropathy in Italy during the last three decades. These studies covered procedures to prevent contrast-induced nephropathy or aimed to identify risk factors, biomarkers, and scores, and their related prognosis.

Background In 2019, a multidisciplinary panel of experts from eight Italian scientific paediatric societies developed a consensus document for the use of inhaled corticosteroids in the management and prevention of the most common paediatric airways disorders. The aim is to provide healthcare providers with a multidisciplinary document including indications useful in the clinical practice. The consensus document was intended to be addressed to paediatricians who work in the Paediatric Divisions, the Primary Care Services and the Emergency Departments, as well as to Residents or PhD students, paediatric nurses and specialists or consultants in paediatric pulmonology, allergy, infectious diseases, and ear, nose, and throat medicine. Methods Clinical questions identifying Population, Intervention(s), Comparison and Outcome(s) were addressed by methodologists and a general agreement on the topics and the strength of the recommendations (according to the GRADE system) was obtained following the Delphi method. The literature selection included secondary sources such as evidence-based guidelines and systematic reviews and was integrated with primary studies subsequently published. Results The expert panel provided a number of recommendations on the use of inhaled corticosteroids in preschool wheezing, bronchial asthma, allergic and non-allergic rhinitis, acute and chronic rhinosinusitis, adenoid hypertrophy, laryngitis and laryngospasm. Conclusions We provided a multidisciplinary update on the current recommendations for the management and prevention of the most common paediatric airways disorders requiring inhaled corticosteroids, in order to share useful indications, identify gaps in knowledge and drive future research.

IntroductionAlthough the European Medicines Agency (EMA) encourage coronavirus disease 2019 (COVID-19) vaccination in pregnant women, the scientific evidence supporting the use of COVID-19 vaccines during pregnancy is still limited.AimWe aimed to investigate adverse events following immunization (AEFI) with COVID-19 vaccines during pregnancy.MethodsWe retrieved Individual Case Safety Reports (ICSRs) related to the use of COVID-19 vaccines during pregnancy from the EudraVigilance database for the year 2021. We analyzed AEFI related to the mother and fetus/newborn. The reporting odds ratio (ROR) was computed to compare the reporting probability of spontaneous abortion between COVID-19 vaccines.ResultsDuring the study period, among 1,315,315 ICSRs related to COVID-19 vaccines, we retrieved 3,252 (0.25%) reports related to the use in pregnancy. More than half (58.24%) of ICSRs were submitted by non-healthcare professionals. Although the majority (87.82%) of ICSRs concerned serious AEFI, their outcomes were mostly favorable. In this study, 85.0% of total ICSRs referred to pregnant women (n = 2,764), while 7.9% referred to fetuses/newborns (n = 258). We identified 16,569 AEFI. Moreover, 55.16% were AEFI not related to pregnancy (mostly headache, pyrexia, and fatigue), while 17.92% were pregnancy-, newborn-, or fetus-related AEFI. Among pregnancy-related AEFI, the most reported was spontaneous abortion. Messenger RNA (mRNA) vaccines had a lower reporting probability of spontaneous abortion than viral vector-based vaccines (ROR 0.80, 95% CI 0.69–0.93). Moderna and Oxford-AstraZeneca vaccines had a higher reporting probability of spontaneous abortion (ROR 1.2, 95% CI 1.05–1.38 and ROR 1.26, 95% CI 1.08–1.47, respectively), while a lower reporting probability was found for Pfizer-BioNTech vaccine compared with all other COVID-19 vaccines (ROR 0.73, 95% CI 0.64–0.84). In addition, 5.8% of ICSRs reported a fatal outcome.ConclusionsNo strong insight of unknown AEFI associated with COVID-19 vaccination in pregnant women was observed. Considering the high risk associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, our analysis suggests that the benefits of COVID-19 vaccines during pregnancy outweigh the possible risks. However, it is important to continue monitoring the safety profile of COVID-19 vaccines in this subpopulation.

BackgroundBlinatumomab is a bispecific CD19-directed CD3 T-cell engager that has proven efficacy in children with relapsed or refractory B-cell acute lymphoblastic leukemia (ALL). Despite its efficacy, it has also been associated with the development of potentially serious adverse events such as the cytokine release syndrome (CRS) and neurologic events. The present meta-analysis aimed to assess the safety profile of blinatumomab in terms of serious adverse events, CRS, and neurologic events (such as seizure and encephalopathy) in pediatric patients with B-cell ALL.Methods and findingsA systematic review was conducted in Pubmed up to December 10, 2021 to retain pediatric clinical trials on blinatumomab. A random effect meta-analysis approach was used. This study followed the PRISMA statement. Four out of the 255 initial references were selected, of which 2 were phase 1/2 clinical trials and 2 phase 3 clinical trials. Blinatumomab was associated with a lower risk of serious adverse events (Risk ratio RR, 0.56; 95% CI, 0.32–0.99), febrile neutropenia (RR, 0.13; 95% CI, 0.06–0.26), infection (RR, 0.40; 95% CI, 0.29–0.56), and grade ≥ 3 adverse events (RR, 0.79; 95% CI, 0.67–0.93) compared to chemotherapy. No difference in the risk of CRS (RR, 8.37; 95% CI, 0.27–260.97) and seizure (RR, 6.43; 95% CI, 0.79–53.08) was observed between groups, while for encephalopathy a higher risk was associated with blinatumomab compared to chemotherapy (RR, 8.90; 95% CI, 1.08–73.29).ConclusionOur data support the good safety profile of bliantumomab in treating pediatric patients with B-ALL.

Few data have been published on the effects of impaired glucose metabolism induced by COVID-19 vaccines. We decided to perform a study to describe Individual Case Safety Reports (ICSRs) of impaired glucose metabolism events reported in the European database (Eudravigilance, EV). ICSRs were retrieved from the online website of Eudravigilance. The reporting odds ratios (ROR) were computed to assess the reporting frequency for COVID-19 mRNA vaccines compared to COVID-19 viral vector-based vaccines. A total of 3917 ICSRs with a COVID-19 vaccine suspected were retrieved, with a total of 4275 impaired glucose metabolism events. Overall, the most reported events were related to “high glucose levels” (2012; 47.06%). The mRNA vaccines were associated with an increased reporting frequency of “type 1 diabetes mellitus” (ROR 1.86; 95% CI 1.33–2.60), “type 2 diabetes mellitus” (ROR 1.58; 95% CI 1.03–2.42), “high glucose levels” (ROR 1.16; 95% CI 1.06–1.27), “diabetes mellitus inadequate control” (ROR 1.63; 95% CI 1.25–2.11), and “hypoglycemia” (ROR 1.62; 95% CI 1.41–1.86) compared to viral vector-based vaccines. mRNA COVID-19 vaccines were associated with an increased reporting frequency of alterations of glucose homeostasis compared to viral-vector COVID-19 vaccines. Clinicians should be aware of these events to better manage glycemic perturbations. Larger nationwide studies are warranted to verify these findings.

Immune checkpoint inhibitors (ICIs) are widely used improving clinical outcomes in many cancer patients. However, they can induce serious consequences, like neurological immune-related adverse drug reactions (NirADRs). Although these are rare complications, they can be serious with important impact on patients’ quality of life. Our purpose is to describe these adverse events observed in the European clinical practice context. We carried out a descriptive analysis of individual case safety reports (ICSRs) related to ICIs collected until February 7, 2020, in the European spontaneous reporting database, EudraVigilance, and reported nervous disorders as suspect adverse drug reactions (ADRs). NirADRs were classified according to the Medical Dictionary for Regulatory Activities (MedDRA). In order to identify a hypothetical different reporting probability of the NirADR types between the ICI classes, we carried out a disproportionality analysis. The reporting odds ratio (ROR) with 95% CI was computed comparing the different ICI classes to each other based on their pharmacological target [the cytotoxic T-lymphocyte antigen-4 (CTLA-4), the programmed death-1 (PD-1) or its ligand (PD-L1)]. Finally, we researched in the literature the hypothesized mechanisms, which could explain the onset of these ICI-related neurological complications. Overall, we found 4,875 cases describing 6,429 ICI-related suspected NirADRs. ICI-related neurotoxicities include a wide range of central and peripheral events. These were mainly related to anti-PD-1 agents and occurred in male patients (59%). Our analysis confirmed a gender difference of NirADRs. Twenty-three percent of the events (comprising myasthenia gravis, neuropathy peripheral, and cerebral infarction) had unfavorable fallouts, including fatal outcome (7%). Majority of the NirADRs were categorized as “Neurological disorders NEC” HLGTs MedDRA (2,076; 32%). In 1,094 cases (22%), more NirADRs overlapped with other neurologic complications. An interesting overlapping of myasthenia gravis with myositis or myocarditis emerged. From our disproportionality analysis, an increased reporting probability of peripheral neuropathies and headaches emerged with ipilimumab when compared to anti-PD-1 and anti-PD-L1 agents. However, neuromuscular disorders were more probably reported with anti-PD-1. Several pathogenic mechanisms, including neuronal damage by T cells and autoantibodies and/or cytokine-mediated inflammation processes, have been hypothesized. However, the pathogenesis of these ICI-related complications is not completely understood. Considering the recent marketing authorizations of ICIs, further studies are strongly needed to monitor their neurologic safety profile.

Dapagliflozin was associated with an increased risk of diabetic ketoacidosis that has led to the European withdrawal of the authorization for the type 1 diabetes. However, it is still used for the treatment of type 2 diabetes. Therefore, we aim to evaluate the occurrence of dapagliflozin-induced ketoacidosis events by using the European spontaneous reporting system. The reporting odds ratios (ROR) were computed to assess the reporting frequency of ketoacidosis events for dapagliflozin compared to Dipeptidyl peptidase-4 (DPP-4) inhibitors, insulins, or all other Sodium-glucose cotransporter-2 (SGLT-2) inhibitors. A total of 2406 cases with dapagliflozin reported at least one event of ketoacidosis. The three most reported events were: diabetic ketoacidosis (1412; 55.39%), ketoacidosis (476; 18.67%), and euglycaemic diabetic ketoacidosis (296; 11.61%). Dapagliflozin was associated with the higher reporting frequency of ketoacidosis events compared to DPP-4 inhibitors (ROR 12.07, 95%CI 11.67–13.81) or insulins (ROR 7.59, 95%CI 7.13–7.89). A lower reporting frequency was instead observed compared to other SGLT2 inhibitors (ROR 0.91, 95%CI 0.87–0.96). Considering the higher reporting frequency of ketoacidosis observed with dapagliflozin then DPP-4 inhibitors or insulins, attention should be given to patients treated with this drug.

Objectives: Human papillomavirus (HPV) vaccines have proved to be effective in preventing cervical carcinoma. Although their safety profile resembled those of any other vaccine, few clinical studies showed that HPV vaccines might also induce severe adverse events. Methods: The authors aimed to investigate the safety profile of HPV vaccines, by analyzing the individual case safety reports (ICSRs) of a suspected adverse event following immunization (AEFI) concerning HPV vaccines that were sent to the Italian Pharmacovigilance Spontaneous Reporting System (RNF) in the Campania Region from January 2007 to September 2018. Results: During the study period, 82 ICSRs, covering 181 AEFIs, related to HPV vaccines were sent to the RNF in the Campania Region. The mean age of patients who experienced an AEFI after HPV vaccinations was 13 ± 4.5 years. The majority of ICSRs reported AEFIs that were considered as not serious (82%) and that had a favorable outcome (93%). Conclusion: The overall results of the study demonstrated that, except for a few cases, AEFIs related to HPV vaccines reflect those already reported in the summary of product characteristics. The authors did not identify any new safety issues or serious, rare or unexpected AEFIs that were medically confirmed to be related to HPV vaccines.

The renin-angiotensin-aldosterone system (RAAS) firstly considered as a cardiovascular circulating hormonal system, it is now accepted as a local tissue system that works synergistically or independently with the circulating one. Evidence states that tissue RAAS locally generates mediators with regulatory homeostatic functions, thus contributing, at some extent, to organ dysfunction or disease. Specifically, RAAS can be divided into the traditional RAAS pathway (or classic RAAS) mediated by angiotensin II (AII), and the non-classic RAAS pathway mediated by angiotensin 1–7. Both pathways operate in the heart and lung. In the heart, the classic RAAS plays a role in both hemodynamics and tissue remodeling associated with cardiomyocyte and endothelial dysfunction, leading to progressive functional impairment. Moreover, the local classic RAAS may predispose the onset of atrial fibrillation through different biological mechanisms involving inflammation, accumulation of epicardial adipose tissue, and electrical cardiac remodeling. In the lung, the classic RAAS regulates cell proliferation, immune-inflammatory response, hypoxia, and angiogenesis, contributing to lung injury and different pulmonary diseases (including COVID-19). Instead, the local non-classic RAAS counteracts the classic RAAS effects exerting a protective action on both heart and lung. Moreover, the non-classic RAAS, through the angiotensin-converting enzyme 2 (ACE2), mediates the entry of the etiological agent of COVID-19 (SARS-CoV-2) into cells. This may cause a reduction in ACE2 and an imbalance between angiotensins in favor of AII that may be responsible for the lung and heart damage. Drugs blocking the classic RAAS (angiotensin-converting enzyme inhibitors and angiotensin receptor blockers) are well known to exert a cardiovascular benefit. They are recently under evaluation for COVID-19 for their ability to block AII-induced lung injury altogether with drugs stimulating the non-classic RAAS. Herein, we discuss the available evidence on the role of RAAS in the heart and lung, summarizing all clinical data related to the use of drugs acting either by blocking the classic RAAS or stimulating the non-classic RAAS.

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.

Introduction: Multiple sclerosis (MS) is a chronic immune-mediated inflammatory disorder of the brain and spinal cord characterized by inflammation, demyelination, and axonal degeneration. Area covered: Even though the pharmacological armamentarium for MS treatment is considerably improved in the last 20 years, safety data especially for the second-line and innovative treatments are lacking. In order to analyze the safety profile of drugs used for the treatment of MS, a literature review of pre-marketing, post-marketing studies and case reports was performed. Expert opinion: Nowadays, the numerous drugs approved in the last years for the treatment of MS allow a better control of the disease and a better patient compliance. The main advantages of the new disease-modifying agents for MS (DMTs), in fact, derive from the new oral administration and the prolonged half-life with consequent improvement in compliance compared to first-line therapy which required subcutaneous administrations. However, DMTs can cause serious, sometimes life-threatening or fatal, drug adverse reactions. Due to the lack of safety data and given the recent marketing approval of the last DMTs for MS, observational studies and post-marketing surveillance activities will be necessary in order to improve the knowledge about the safety profile of these drugs and the improvement of their use in clinical practice. © 2017 Informa UK Limited, trading as Taylor & Francis Group.
