UNASSIGNED: Compartment syndrome is an uncommon but life-threatening condition. No study has comprehensively compared compartment syndrome (CS) association with available drugs. The objective of this study was to estimate the association between CS and drugs using the FDA Adverse Event Report System (FAERS).
UNASSIGNED: FAERS reports from the first quarter of 2004 to the third quarter of 2023 were analyzed. The Medical Dictionary for Regulatory Activities (MedDRA) was used to identify CS cases. Reporting odds ratio (ROR), corresponding to 95% confidence intervals (95% CI) were calculated to detect a positive signal.
UNASSIGNED: A total of 2197 reports were considered in the study after the inclusion criteria were applied. Totally 100 drugs were found to be associated with CS. The median time for drug-associated CS was 45 days.
UNASSIGNED: By analyzing the FAERS database, the study revealed that certain drugs are significantly associated with compartment syndrome. Further studies are needed to verify whether these drugs are associated with such a risk.

Background: Immune checkpoint inhibitors (ICIs), including anti-PD-1, anti-PD-L1 and anti-CTLA-4 antibodies, have become a standard treatment for multiple cancer types. However, ICIs can induce immune-related adverse events, with hepatitis-related adverse events (HRAEs) being of particular concern. Our objective is to identify and characterize HRAEs that exhibit a significant association with ICIs using real-world data. Methods: In this observational and retrospective pharmacovigilance study, we extracted real-world adverse events reports from the FDA Adverse Event Reporting System database spanning from the first quarter of 2004 to the first quarter of 2023. We conducted both Frequentist and Bayesian methodologies in the framework of disproportionality analysis, which included the reporting odds ratios (ROR) and information components (IC) to explore the intricate relationship between ICIs and HRAEs. Results: Through disproportionality analysis, we identified three categories of HRAEs as being significantly related with ICIs, including autoimmune hepatitis (634 cases, ROR 19.34 [95% CI 17.80-21.02]; IC025 2.43), immune-mediated hepatitis (546 cases, ROR 217.24 [189.95-248.45]; IC025 4.75), and hepatitis fulminant (80 cases, ROR 4.56 [3.65-5.70]; IC025 0.49). The median age of patients who report ICI-related HRAEs was 63 years (interquartile range [IQR] 53.8-72), with a fatal outcome observed in 24.9% (313/1,260) of these reports. Cases pertaining to skin cancer, lung cancer, and kidney cancer constituted the majority of these occurrences. Patients treated with anti-PD-1 or anti-PD-L1 antibodies exhibited a higher frequency of immune-mediated hepatitis in comparison to those undergoing anti-CTLA-4 monotherapy, with a ROR of 3.59 (95% CI 1.78-6.18). Moreover, the dual ICI therapy demonstrated higher reporting rates of ICI-related HRAEs compared to ICI monotherapy. Conclusion: Our findings confirm that ICI treatment carries a significant risk of severe HRAEs, in particular autoimmune hepatitis, immune-mediated hepatitis, and hepatitis fulminant. Healthcare providers should exercise heightened vigilance regarding these risks when managing patients receiving ICIs.

UNASSIGNED: Intravesical therapy is a commonly utilized treatment for non-muscle invasive bladder cancer (NMIBC). This study focuses on summarizing the signals of all intravesical drugs and aims to highlight the comprehensive differences in adverse events (AEs) between these drugs.
UNASSIGNED: We conducted pharmacovigilance data analysis based on the real-world big data from the Food and Drug Administration Adverse Event Reporting System (FAERS) database.
UNASSIGNED: We elucidated all signals compared with the overall FAERS database or other administration routes for Bacillus Calmette-Guerin (BCG), mitomycin, gemcitabine, valrubicin, and epirubicin. Notably, the distribution of reported AEs associated with intravesical therapy exhibited a noticeable inclination toward male patients. Furthermore, all five drugs demonstrated a disproportionate distribution in local AEs, particularly in renal and urinary disorders. Additionally, specific signals and findings were summarized for each individual drug. Finally, we highlighted the AEs that resulted in serious outcomes for each drug.
UNASSIGNED: We have compiled an overview of the AEs tied to intravesical drugs whilst considering their individual distinctions. These insightful findings serve to enrich our comprehension of the safety profiles and potential risks linked to intravesical therapy.

OBJECTIVE: Valbenazine is commonly used to treat tardive dyskinesia, and we conducted a pharmacovigilance analysis using the Food and Drug Administration Adverse Event Reporting System (FAERS) to evaluate neurological safety signals associated with valbenazine.
METHODS: Data was collected in FAERS from the second quarter of 2017 to the fourth quarter of 2023 for data cleaning. Neurological adverse event (AE) signals of valbenazine were mined by calculating reporting odds ratios (ROR), information component (IC) and empirical Bayesian geometric mean (EBGM). The serious and non-serious cases and signals were prioritized using a rating scale.
RESULTS: The number of neurological AE reports where the primary suspect (PS) drug was 8981 for valbenazine. Significant AE signals were identified by the preferred term (PT) analysis for valbenazine, including somnolence (ROR 19.69), tremor (ROR 15.17), and tardive dyskinesia (ROR 236.91), among which 18 AEs were identified as new signals. Patient age (p < 0.009) and sex (p = 0.197) might be associated with an increased risk of neurological AE severity. Notably, the association between valbenazine and neurological disorders remained when stratified by sex, age, and reporter type. AE timing analysis was performed for the drug and four moderate clinical priority signals [i.e., somnolence, balance disorder, parkinsonism, and akathisia (priorities 7)], showing the same early failure type profiles.
CONCLUSIONS: The increase in neurological safety signals is identified in the post-marketing research of valbenazine. Clinicians need to pay attention to not only common AEs but also be alert to new neurological AE signals when using valbenazine.

UNASSIGNED: Lasmiditan offers a promising option for the treatment of migraines, particularly for individuals with cardiovascular concerns. It is crucial to gather comprehensive safety information of lasmiditan through large-scale post market monitoring.
UNASSIGNED: This study assessed the safety profile of lasmiditan based on real-world data of FDA Adverse Event Reporting System (FAERS) database. Four disproportionality analysis methods were applied to mining the significant signals. The differences in adverse event signals among different subgroups were investigated concerning race, sex, age, weight, dose, and concomitant drug.
UNASSIGNED: A total of 820 reports and 1,661 adverse events with lasmiditan as the primary suspected drug were identified. Two new adverse event signals related to nervous system disorders emerged. Females and males were more likely to develop paresthesia and dizziness, respectively. Most common adverse events were more likely to occur in the elderly patients and at high doses.
UNASSIGNED: It is essential to be vigilant about the relation of potential nervous system disorders with lasmiditan. The importance of heightened clinical vigilance regarding paresthesia in females and dizziness in males was underscored. Additionally, it is advised to administer a lower initial dose for elderly patients.

BACKGROUND: Sugammadex, a selective steroidal neuromuscular blocking agent reversal agent, is increasingly employed for the rapid restoration of neuromuscular function. This study aimed to conduct a comprehensive evaluation of sugammadex\'s safety profile.
METHODS: Adverse events (AEs) related to sugammadex reported in the FDA Adverse Event Reporting System (FAERS) database from January 2009 to September 2023 were extracted. Disproportionality analysis with four measures: reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and multi-item gamma Poisson shrinker (MGPS) were employed to detect significant AEs. We also inspected for unexpected AEs absent from the sugammadex FDA approval documentation and categorized AEs based on the latest version (26.1) of \'Important Medical Event Terms List (IME list)\' developed by the EudraVigilance Expert Working Group.
RESULTS: A total of 1452 reports were linked to sugammadex. At the preferred terms (PTs) levels, 98 sugammadex-related AEs were identified, including \"anaphylactic reaction\", \"bradycardia\", \"bronchospasm\" and \"cardiac arrest\". Among them, 37 representing unexpected events were absent from official FDA labeling, and 50 AEs were recognized as IME warranting observation. Notably, 19 PTs denoted serious AEs were absent from labeling yet needing IME surveillance, including: \"Kounis syndrome\", \"angioedema\", \"pulseless electrical activity\" and \"laryngeal edema\".
CONCLUSIONS: The study identified unexpected and potentially life-threatening AEs associated with sugammadex, a valuable agent for rapidly reversing neuromuscular blockade. Clinicians are advised to be mindful of these potential risks, particularly in patients with allergies or existing cardiovascular or respiratory conditions.

BACKGROUND: Although immune checkpoint inhibitors (ICIs) combined with angiogenesis inhibitors (AGIs) has become increasingly used for cancers, the impact of combination therapy on immune-related adverse events (irAEs) in real-world settings has not been well elucidated to date.
METHODS: The FDA Adverse Event Reporting System (FAERS) database from 2014 to 2022 was retrospectively queried to extract reports of irAEs referred as standardized MedDRA queries (SMQs), preferred terms (PTs) and system organ classes (SOCs). To perform disproportionality analysis, information component (IC) and reporting odds ratio (ROR) were calculated and lower limit of 95 % confidence interval (CI) for IC (IC025) > 0 or ROR (ROR025) > 1 with at least 3 reports was considered statistically significant.
RESULTS: Compared to ICIs alone, ICIs + AGIs demonstrated a lower IC025/ROR025 for irAEs-SMQ (2.343/5.082 vs. 1.826/3.563). Regarding irAEs-PTs, there were fewer irAEs-PTs of significant value in ICIs + AGIs than ICIs alone (57 vs. 150 PTs) and lower signal value for most PTs (88 %) in ICIs + AGIs. Moreover, lower IC025 for most of irAEs-SOCs in ICIs + AGIs (11/13) compared with ICIs alone was observed. As for outcomes of irAEs, ICIs + AGIs showed a lower frequency of \"fatal\" for irAEs-SMQ than ICIs alone (4.88 % vs. 7.83 %), so as in cardiac disorder (SOC) (15.45 % vs. 26.37 %), and respiratory, thoracic and mediastinal disorders (SOC) (13.74 % vs. 20.06 %). Similarly, there were lower occurrence and fewer fatality of irAEs in ICIs + AGIs + chemotherapy (CT) than ICIs + CT.
CONCLUSIONS: ICIs combined with AGIs may reduce incidence and mortality for most of irAEs compared to ICIs alone whether or not with CT.

UNASSIGNED: Tumor necrosis factor-α inhibitors (TNFis) are used for the treatment of inflammatory bowel disease (IBD). The aim of this study was to evaluate the association between neurological adverse events (AEs) and TNFi use.
UNASSIGNED: Data of TNFis indicated for IBD were collected from the Food and Drug Administration Adverse Event Reporting System (FAERS) from the marketed date to the second quarter of 2023. The reporting odds ratio (ROR) and a Bayesian confidence propagation neural network were used to identify signals.
UNASSIGNED: A total of 4,964 neurological AEs were reported in the IBD population. Infliximab had 3 signals, including demyelination [ROR (95% CI): 1.69 (1.33,2.15)], meningitis listeria [ROR (95% CI): 5.05 (3.52,7.25)], and optic neuritis [ROR (95% CI): 1.72 (1.3,2.26)]. The signals for adalimumab were gait disturbance [ROR (95% CI): 1.43 (1.32,1.56)] and muscular weakness [ROR (95% CI): 1.4 (1.27,1.55)]. A peripheral neuropathy signal was found for adalimumab [ROR (95% CI): 1.34 (1.18,1.53)] and certolizumab pegol [ROR (95% CI): 1.49 (1.07,2.08)]. However, there were no signals among neurological AEs for golimumab.
UNASSIGNED: Neurological signals were detected for TNFi use, indicating that the risk of neurological AEs requires additional attention in clinical use of TNFis.

UNASSIGNED: As a novel drug formulation, antibody drug conjugates (ADCs) are widely used in various types of cancer. However, clinically, there is a lack of attention to the CVD produced by them, as well as a lack of research on the real-world situation. Using the Food and Drug Administration Adverse Event Reporting System (FAERS) database, to ensure its clinical safety application, we analyzed post-marketing data on antitumor ADCs to identify risk factors and drugs associated with the risk of cardiovascular events.
UNASSIGNED: We used OpenVigil 2.1 to conduct a database query for adverse events (AEs) reported to the FAERS database between the time the drug was launched and the second quarter of 2023. Cardiovascular adverse events (AEs) were grouped into fourteen narrow categories using the Standardized Medical Dictionary for Regulatory Activities (MedDRA) Queries (SMQs), and the reporting odds ratio (ROR) and the proportional reporting ratio (PRR) for reporting the association between different drugs and cardiovascular disease (CVD) risk were calculated.
UNASSIGNED: In the FAERS database, 1863 AEs associated with CVD we studied were identified in patients receiving ADC therapy. Most reports came from people aged ≥65, but a significant number of cases were found to be unknown. The number of patients with antibody-drug conjugates (ADCs)-related CVD cases aged <18 years, 18-64 years, and≥ 65 years was 52 (2.79%), 586 (31.45%), and 613 (32.90%), respectively. The proportion of female patients (834, 44.77%) was higher than that of male patients (752, 40.37%). Death (770 reports), disability (9 reports), Hospitalization initial or prolonged (407 reports), and life-threatening reactions (187 reports). Of the 770 deaths reported, 103 (31.7%) were associated with brentuximab vedotin, 10 (24.4%) with sacituzumab govitecan, 22 (19.3%) with enfortumab vedotin, and 35 (34.7%) with trastuzumab emtansine.49 (41.2%) cases were associated with polatuzumab vedotin, 62 (29%) with trastuzumab deruxtecan, 423 (54.3%) with gemtuzumab ozogamicin, and 66 (38.8%) with inotuzumab ozogamicin. In a disproportionate number of SMQS, cardiac failure (n = 277) and embolic and thrombotic events, venous (n = 446) were the most frequently reported CVD-related AEs in ADCs.
UNASSIGNED: By mining the FAERS database, we provided relevant information on the association between ADC use and cardiovascular-associated AEs. ADCs were associated with increased cardiovascular toxicity, deserving distinct monitoring and appropriate management. Further research is needed to confirm these findings and assess causality.

UNASSIGNED: Our study aims to characterize the ocular safety profiles of phosphodiesterase type 5 (PDE5) inhibitors and explore the differences among different PDE5 inhibitors.
UNASSIGNED: We analyzed reports on ocular adverse events associated with sildenafil, vardenafil and tadalafil submitted to the FDA Adverse Event Reporting System (FAERS) database from the first quarter of 2004 to the first quarter of 2023. Disproportionality analysis was conducted to evaluate reporting risk profiles.
UNASSIGNED: Among 61,211 reports qualifying for analysis, 5,127 involved sildenafil, 832 vardenafil, and 3,733 tadalafil. All PDE5 inhibitors showed increased reporting odds ratios (ROR) for ocular adverse events, with vardenafil highest (ROR 4.47) followed by sildenafil and tadalafil. Key ocular adverse events included cyanopsia, optic ischemic neuropathy, visual field defects, unilateral blindness and blindness. Sildenafil showed the highest disproportionality for cyanopsia (ROR 1148.11) while vardenafil and tadalafil showed the highest disproportionality for optic ischemic neuropathy. Time-to-onset analysis also revealed significant differences, with sildenafil having a later median time-to-onset compared to vardenafil and tadalafil.
UNASSIGNED: This comprehensive pharmacovigilance study reveals distinct patterns of ocular adverse events associated with PDE5 inhibitors. These findings contribute to a better understanding of the safety profiles of PDE5 inhibitors and may guide healthcare professionals in clinical decision-making.
