Introduction: Although immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, the consequential over activation of the immune system is often complicated by adverse events that can affect several organs and systems, including the nervous system. The precise pathophysiology underlying neurological irAEs (n-irAEs) is not completely known. Around 3.8% of patients receiving anti-CTLA-4 agents, 6.1% of patients receiving anti-PD-1/PD-L1, and 12% of patients receiving combination therapies have n-irAEs. Most n-irAEs are low-grade, while severe toxicities have rarely been reported. in this article, we performed an updated literature search on immuno-related neurotoxicity on main medical research database, from February 2017 to December 2023.

Areas covered: We have also compared the latest national and international guidelines on n-irAEs management with each other in order to better define patient management.

Expert opinion: A multidisciplinary approach appears necessary in the management of oncological patients during immunotherapy. Therefore, in order to better manage these toxicities, we believe that it is essential to collaborate with neurologists specialized in the diagnosis and treatment of n-irAEs, and that a global neurological assessment, both central and peripheral, is necessary before starting immunotherapy, with regular reassessment during treatment.

Objectives: Direct factor Xa inhibitors rivaroxaban, apixaban, and edoxaban, commonly used direct oral anticoagulant (DOAC), are widely used to prevent and treat stroke and venous thromboembolic events in patients with atrial fibrillation (AF). This study aimed to assess and compare reports of adverse events associated with rivaroxaban, apixaban, and edoxaban, including hemorrhagic and non-hemorrhagic events.

Methods: Reporting odds ratio (ROR), proportional reporting ratio (PRR), Medications and Health Care Products Regulatory Agency (MHRA), and the information component (IC) were used to perform a risk assessment of adverse event reports in the FDA Adverse Event Reporting System (FAERS) database for the years 2018-2022.

Results: Combined with disproportionality analysis in different backgrounds, the salient risks of the three-factor Xa inhibitors varied. Rivaroxaban had the most significant risk of hemorrhage, apixaban had a higher incidence and risk of death, cardiac and cerebral adverse events, and edoxaban showed a more prominent risk in the kidneys and urinary system.

Conclusion: Hemorrhage is a common risk with factor Xa inhibitors, with rivaroxaban being the most significant. Apixaban and edoxaban also showed significant association with non-hemorrhagic adverse events, and increased attention to non-hemorrhagic adverse events is needed in clinical use.

Background: Alopecia areata (AA) is a non-scarring disorder characterized by hair loss that greatly affects patients' quality of life and has a chronic, recurring course. This disease is marked by an inflammatory process, mainly on an autoimmune basis primarily regulated by Janus kinase (JAK).

Research design and methods: We conducted a retrospective study evaluating the safety of JAKi in a real-world setting in 91 AA patients, with a specific focus on the assessment of infectious events.

Results: Overall, 34 infectious events were observed in 28 patients (30.8%), among them 17 patients (60.7%) suspended treatment with JAKi until the infection was clinically resolved. Only in one case the infectious event led to a permanent discontinuation of the treatment. The data we observed in the study are consistent with results reported in clinical trials.

Conclusion: It can be stated that, during treatment with JAKi in AA patients, infectious events may occur, but in most cases these events are easily manageable and do not result in permanent discontinuation of the drug.

Background: Vinca alkaloids are widely used in cancer treatment for their ability to target microtubule dynamics. While their efficacy in treating certain cancers is well-established, the full spectrum of their adverse event profiles remains an area of ongoing research.

Methods: We analyzed AEs related to vinorelbine and vincristine using a retrospective case/non-case approach with data from the FDA Adverse Event Reporting System (FAERS). We applied various algorithms to detect AE signals: the reporting odds ratio (ROR) and proportional reporting ratio (PRR) measured disproportionality and association strength; the Bayesian confidence propagation neural network (BCPNN) calculated the Information Component (IC) for associations against background rates; and the multi-item gamma Poisson shrinker (MGPS) yielded empirical Bayes geometric mean (EBGM) values, accounting for reporting variability.

Results: Both medications significantly involve the blood and lymphatic systems, with vinorelbine reporting 401 cases in this System Organ Class (SOC), exhibiting a ROR of 17.4, PRR of 12.4, IC of 3.63, and EBGM of 12.38. An intersection analysis of Preferred Terms (PTs) has uncovered previously unreported AEs shared by both drugs, including posterior reversible encephalopathy syndrome and inappropriate antidiuretic hormone secretion.

Conclusions: This analysis highlights the need for ongoing research of the risks associated with vinorelbine and vincristine.

Background: Tralokinumab is a fully human IgG4 monoclonal antibody targeting IL-13, used for treating atopic dermatitis. This study analyzed tralokinumab-related adverse drug events by mining the Food and Drug Administration Adverse Event Reporting System (FAERS) database to provide a safety reference for clinical application.

Methods: Adverse drug event reports from Q1 2022 to Q2 2024 were extracted from the FAERS database. After standardizing the data, various signal detection methods were used for analysis, including ROR, PRR, BCPNN, and MGPS.

Results: A total of 1,820 reports of adverse events (AEs) with tralokinumab as the primary suspected drug were identified. 70 preferred terms (PTs) met the criteria across four signal detection methods, involving 11 system organ classes (SOCs). These included known adverse reactions like conjunctivitis and injection site reactions, and signals not previously reported in clinical trials, such as eye pruritus, dry eye, eye swelling, pneumonia pneumococcal, and cutaneous T-cell lymphoma. Most AEs occurred within one month of initiating tralokinumab treatment.

Conclusions: Based on the FAERS database, this study comprehensively and systematically analyzed AE signals in tralokinumab treatment. The results enhance the understanding of tralokinumab's safety and serve as valuable references for reducing the risk of adverse reactions during clinical use.

Introduction: Oral anticoagulant drugs reduce the risk of stroke associated with atrial fibrillation. Vitamin K antagonists, gold standard therapy for decades, have been deposed by the direct oral anticoagulants that exhibit superior safety profiles. However, hemorrhagic complications remain a major concern to anticoagulation.

Areas covered: We searched available data in the literature to review the current knowledge on the safety profiles of available anticoagulants.

Expert opinion: Despite a relevant leap forward with the introduction of DOACs, safety concerns persist in some fields of the current pharmacotherapy for stroke prevention in atrial fibrillation. In-depth knowledge of the safety profile of available anticoagulants and dealing with safety issues in patient subgroups is of utmost importance. Bleeding risk scores should not be dichotomously used to decide anticoagulation treatment but rather to promote shared decision, identify and correct modifiable risk factors, and set monitoring frequency. Additional issues that wait to be investigated in order to improve the safety of therapy include circulating levels of direct oral anticoagulants and anticoagulation in patient sub-groups: very elderly, frail, those with advanced kidney or liver disease, and so on. Safety may be improved from the in-depth knowledge of safety concerns and therapeutic options.

Background: Leuprorelin, a gonadotropin-releasing hormone agonist, is widely used to treat hormone-related disorders. This study aims to explore and analyze the safety profile of leuprorelin by examining adverse event reports from the FDA Adverse Event Reporting System (FAERS) database.

Methods: This study conducted a retrospective pharmacovigilance analysis using FAERS data from Q1 2004 to Q1 2024. Adverse drug events (ADEs) related to leuprorelin were identified and categorized by system organ class and specific adverse events. Statistical methods such as Proportional Reporting Ratio (PRR), Reporting Odds Ratio (ROR), Bayesian Confidence Propagation Neural Network (BCPNN), and Empirical Bayesian Geometric Mean (EBGM) were used to detect safety signals.

Results: A total of 63,928 ADE reports implicated leuprorelin, with 500 preferred terms and 25 system organ classes showing significant disproportionality. Notable rare ADEs identified were bulbospinal muscular atrophy congenital (n = 26; ROR 1282.72, PRR 1282.52, IC 7.91, EBGM 241.28), follicular cystitis (n = 3; ROR 126.84, PRR 126.84, IC 6.48, EBGM 89.09), and anaplastic meningioma (n = 3; ROR 46.73, PRR 46.73, IC 5.34, EBGM 40.5).

Conclusion: Most findings were expected, but new signals like follicular cystitis, previously unreported, emerged. Further studies are essential to validate these findings, crucial for clinical monitoring and risk identification of leuprorelin.

Introduction: Carbamazepine (CBZ) is a commonly used antiseizures medications (ASM), but its adverse drug reactions (ADRs) can impact the successful management of epilepsy. There are currently limited systematic studies on ADRs related to CBZ, necessitating further investigation.

Areas covered: Using the FDA Adverse Event Reporting System (FAERS) database , we extracted reports where CBZ was the primary suspect, conducting subgroup analyses stratified by sex and age. Four risk signal detection methods ROR, PRR, BCPNN, and EGBM were employed to systematically analyze the ADRs associated with CBZ.

Expert opinion: In the epilepsy population, ADRs related to CBZ often involve examinations, hereditary disorders, and infections. Subgroup analysis showed differences in ADR signals among male, female, elderly, and young patients. Human Herpesvirus 6 Infection and Dermatitis Exfoliative were consistent CBZ-induced ADRs, unaffected by age or sex. The study also identified previously overlooked ADRs such as bone metabolism abnormalities, ocular toxicity, and ototoxicity. Many ADRs linked to CBZ remain underreported. It is crucial to enhance monitoring and information dissemination about CBZ use in epileptic patients. Adjusting medication regimens for high-risk individuals, potentially incorporating acupuncture, traditional Chinese medicine, or alternative anti-seizure medications, should be considered when necessary.
