UNASSIGNED: Information on the incidence and risk factors for diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar nonketotic syndrome (HHNS) caused by tacrolimus has rarely been reported. This study aims to assess the spectrum of DKA/HHNS associated with tacrolimus.
UNASSIGNED: We conducted an observational, retrospective pharmacovigilance study using the Food and Drug Administration adverse event reporting system (FAERS) database. We employed the information component (IC) and reporting odds ratio (ROR) to evaluate the association between tacrolimus and DKA/HHNS.
UNASSIGNED: A total of 232 events were identified as tacrolimus-related DKA/HHNS, 186 cases from DKA and 54 cases from HHNS. The frequency of tacrolimus-associated DKA and HHNS was found to be significantly higher compared to all other drugs. Specifically, HHNS was significantly associated with tacrolimus based on its ROR and IC. There were no significant differences in death and non-death cases in gender, age group, year of reporting and region of reporting.
UNASSIGNED: Our study showed that DKA and HHNS were associated with tacrolimus use. Healthcare professionals should be aware of the possibility of DKA/HHNS following tacrolimus administration, as they were associated with an increased risk of mortality in transplant recipients.

UNASSIGNED: Selective RET-specific tyrosine kinase inhibitors (RET-TKIs) treat RET fusion-positive non-small cell lung cancer (NSCLC), but studies on their cardiovascular toxicities are limited. This study aimed to characterize the cardiovascular toxicities associated with selective RET-TKI in real-world settings.
UNASSIGNED: Data from the United States Food and Drug Administration Adverse Event Reporting System database from 1 January 2020 to 30 June 2023, were analyzed. Two disproportionality methods, information component and reporting odds ratio (ROR) were used.
UNASSIGNED: Both pralsetinib and selpercatinib showed positive signals for hypertension (pralsetinib: ROR: 5.25, 95% CI: 4.40-6.26; selpercatinib: ROR: 2.68, 95% CI: 1.87-3.82). Additionally, pralsetinib showed a positive signal for ischemic heart disease (ROR: 3.92, 95% CI: 2.94-5.23), and selpercatinib for torsade de pointes/QT prolongation (ROR: 2.65, 95% CI: 1.74-4.04). The median time to onset(TTO) of cardiovascular toxicities was 33 days (IQR: 9-73 days) for pralsetinib and 15 days (IQR: 10-50 days) for selpercatinib. The proportion of deaths, life-threatening events, and hospitalizations due to cardiovascular toxicities were 8.57%, 1.19%, and 31.43%, respectively, for total selective RET-TKI.
UNASSIGNED: Selective RET-TKIs are related to multiple cardiovascular toxicities. Pralsetinib was linked to ischemic heart disease, and selpercatinib to torsade de pointes/QT prolongation and thrombotic events.

UNASSIGNED: Randomized clinical trials have reported some safety profiles in inclisiran, but adverse events in real-world remain insufficient. We aim to evaluate the safety of inclisiran in real-world by collecting the data from the FDA Adverse Event Reporting System database.
UNASSIGNED: Disproportionality analysis was performed by utilizing both Frequency method and Bayesian method to mine adverse event signals of inclisiran. A positive signal was deemed significant when adverse event met the criteria of the aforementioned methods simultaneously.
UNASSIGNED: We gathered a total of 2309 adverse event reports. Among these cases, adverse events were more common in females and ≥ 65 years age group. After data analysis, 51 positive signals from 11 system organ classes were identified, involving \"Musculoskeletal and connective tissue disorders,\" \"General disorders and administration site conditions,\" \"Gastrointestinal disorders,\" etc. At the preferred term level, the top three frequently reported adverse events were arthralgia, injection site pain and myalgia. We also found some uncommon but significantly strong adverse event signals (bladder discomfort and sinus pain) which should be taken prudently.
UNASSIGNED: In this study, we analyzed the real-world adverse events of inclisiran more comprehensively and reported some new adverse events, hoping that can offer more safety information for clinical medication.

UNASSIGNED: This study aimed to investigate the association between phosphodiesterase-5 inhibitors (PDE-5i) and hearing impairment adverse events (HIAEs) while providing an overview of the characteristics of drug-related HIAEs.
UNASSIGNED: We conducted a detailed pharmacovigilance analysis using data from the US Food and Drug Administration Adverse Event Reporting System (FAERS) database, covering 2004 to 2022. By calculating the reporting odds ratio (ROR) and the information component (IC), we identified signals that indicate the association between PDE-5i use and HIAEs.
UNASSIGNED: Among the 191,398 reports related to PDE-5i, we identified 2,608 cases of HIAEs. Signals were observed for both PDE-5i monotherapy and polytherapy, indicating combinations of drugs. Avanafil exhibited the strongest signal (ROR: 4.35, 95% CI: 2.56-7.41, IC: 2.09, 95% CI: 0.10-3.51), while vardenafil showed the weakest signal (ROR: 2.69, 95% CI: 2.21-3.28, IC: 1.14, 95% CI: 0.74-2.04). Sildenafil had the highest reported cases (ROR: 3.03, 95% CI: 2.82-3.24, IC: 1.57, 95% CI: 1.34-1.80).
UNASSIGNED: These findings highlight a significant correlation between PDE-5i use and HIAEs, emphasizing the need for careful evaluation in clinical practice and providing appropriate guidance to patients before initiating treatment.

Background: Neuromuscular blocking agents (NMBAs) are primarily used during surgical procedures to facilitate endotracheal intubation and optimize surgical conditions. This study aimed to explore the adverse event signals of NMBAs, providing reference for clinical safety. Methods: This study collected reports of atracurium, cisatracurium, rocuronium, and vecuronium as primary suspect drugs in The US Food and Drug Administration Adverse Event Reporting System (FAERS) from the first quarter of 2004 to the third quarter of 2023. The adverse events (AEs) reported in the study were retrieved based on the Preferred Terms (PTs) of the Medical Dictionary for Regulatory Activities. In addition, we conducted disproportionality analysis on relevant reports using the reporting odds ratio (ROR) method and Bayesian confidence propagation neural network (BCPNN) method. A positive signal was generated when both algorithms show an association between the target drug and the AE. Results: A total of 11,518 NMBA-related AEs were reported in the FAERS database. The most AEs of rocuronium were collected. NMBA-related AEs involved 27 different system organs (SOCs), all of the four NMBAs had positive signals in \"cardiac disorders,\" \"immune system disorders,\" \"respiratory, thoracic and mediastinal disorders\" and \"vascular disorders.\" At the PTs level, a total of 523 effective AEs signals were obtained for the four NMBAs. AEs labled in the instructions such as anaphylaxis (include anaphylactic reaction and anaphylactic shock), bronchospasm, respiratory arrest and hypotension were detected positive signals among all NMBAs. In addition, we also found some new AEs, such as ventricular fibrillation for the four NMBAs, hyperglycaemia for atracurium, kounis syndrome and stress cardiomyopathy for rocuronium, hepatocellular injury for cisatracurium, hyperkalaemia for vecuronium. To further investigated the AEs associated with serious clinical outcomes, we found that cardiac arrest and anaphylaxis were the important risk factors for death due to NMBAs. Conclusion: NMBA-related AEs have a significant potential to cause clinically severe consequences. Our study provides valuable references for the safety profile of NMBAs, and considering the limitations of the FAERS database, further clinical data are needed to validate the findings of this study.

UNASSIGNED: The objective of this research is to scrutinize adverse events (AEs) linked to Trifluridine/Tipiracil (TFTD/TPI), using data from the FDA Adverse Event Reporting System (FAERS) database.
UNASSIGNED: The AEs data related to TFTD/TPI were collected from the fourth quarter of 2015 through the fourth quarter of 2023. After normalizing the data, multiple signal quantification techniques including Proportional Reporting Ratio (PRR), Reporting Odds Ratio (ROR), Bayesian approaches such as Bayesian Confidence Propagation Neural Network (BCPNN) and the Multi-item Gamma Poisson Shrinker (MGPS) were used for overall and subgroup analysis and visualization analyses were performed.
UNASSIGNED: From the FAERS database, we analyzed 13,520,073 reports, identifying 8,331 as primary suspect (PS) AEs for TFTD/TPI, occurring across 27 organ systems. The study retained 99 significant disproportionality Preferred Terms (PTs) across four algorithms and unveiled unexpected serious AEs such as iron deficiency and intestinal perforation, hepatic failure, cholangitis and so on. The median onset of TFTD/TPI-associated AEs was 44 days (IQR 20-97 days), with most occurring within the first 30 days of treatment.
UNASSIGNED: This research uncovers critical new safety signals for TFTD/TPI, supporting its clinical monitoring and risk identification.

OBJECTIVE: Antibiotic utilization stands as the strongest modifiable determinant for Clostridioides difficile infection (CDI). However, previous studies have relied on aggregated antibiotic categories, leaving prescribers without detailed comparative risk information for individual antibiotics. Our objective was to comprehensively estimate CDI risks across specific antibiotics.
METHODS: We integrated 2 methodologies to access and rank the CDI risk associated with individual antibiotics or classes. Initially, we conducted a network comparison by analyzing data from randomized controlled trials (RCTs). Subsequently, a real-world disproportionality analysis using the Food and Drug Adverse Event Reporting System (FAERS) database complemented and enriched the findings from RCTs.
RESULTS: The network comparison, encompassing 61 RCTs with 25,931 patients, revealed that exposure to cefepime (odds ratio [OR] 2.56, 95% confidence interval [CI] 1.20-5.44, P=0.02) and imipenem/cilastatin (OR 3.86, 95%CI 1.61-9.29, P=0.003) exhibited higher frequencies of CDI compared to piperacillin/tazobactam. No statistically significant distinctions emerged among carbapenems, albeit a trend indicating a heightened CDI incidence with imipenem/cilastatin relative to meropenem (OR 3.89, 95%CI 0.94-16.09). In the FAERS disproportionality analysis, nearly all antibiotics displayed associations with CDI, and CDI risk signals often cluster within the majority of antibiotic classes. Among these, lincomycin demonstrated the strongest association (reporting odds ratios 112.17, 95%CI 51.68-243.43). Additionally, oral third-generation cephalosporins tend to exhibit higher CDI risk signals than others.
CONCLUSIONS: Our findings unveiled substantial diversity in CDI risk, both within and among antibiotic classes, providing valuable guidance for clinicians in antibiotic prescription decisions and for initiatives aimed at antibiotic stewardship.

BACKGROUND: This study aimed to elucidate the scope and nature of adverse events (AEs) associated with Yasmin.
METHODS: Among the 17,035,572 AE reports collected from the Food and Drug Administration Adverse Event Reporting System (FAERS) database between January 2004 and September 2023, 25,949 reports involved Yasmin. The demographic details, clinical outcomes, and sources of reports were extracted, and four algorithms were used to evaluate adverse drug reactions.
RESULTS: The majority of the AE reports involved females aged 18-45 years. Hospitalization was the most frequently reported serious outcome (46.84 %), with death occurring in 292 patients (1.82 %). The highest number of reports originated from the United States. Adverse reactions spanned across 24 system organ categories (SOCs), and hepatobiliary, vascular, and psychiatric disorders were the most frequently reported AEs. A total of 229 Preferred Terms (PTs) were identified for adverse reactions, with high signal strength observed for conditions such as post-cholecystectomy syndrome. In addition, fear of disease, which has not been previously identified as an AE related to Yasmin, was also identified as a high signal strength side effect.
CONCLUSIONS: The findings of the present study underscore the importance of monitoring and identifying potential AEs in patients receiving Yasmin, including those not currently listed in the medication instructions.

UNASSIGNED: ThePhosphoinositide 3-kinases (PI3Ks) family plays a crucial role intumorigenesis. Alpelisib (inhibiting PI3Kα), copanlisib (inhibiting PI3Kα andPI3Kδ), duvelisib (inhibiting PI3Kδ and PI3Kγ), and idelalisib (inhibitingPI3Kδ) were developed to target the PI3K pathway. However, the toxicity limitstheir application to some extent. It\'s necessary to investigate the adverseeffects (AEs) of these inhibitors.
UNASSIGNED: We conducted acomparative analysis of the safety signals of AEs in PI3K inhibitors usingdisproportionality analysis in the FDA Adverse Event Reporting System database(FAERS).
UNASSIGNED: Our studyidentified significant safety signals for metabolic disorders with all PI3Kinhibitors. Notable safety signals for gastrointestinal disorders were observedwith most PI3K inhibitors, with the exception of copanlisib. Common AEs shared amongall PI3K inhibitors included colitis and dehydration. Alpelisib displayedunique AEs associated with metabolic disorders, whereas copanlisib exhibitedidiosyncratic AEs linked to cardiac and vascular disorders. Stevens-Johnsonsyndrome emerged as a common severe adverse event (SAE) among alpelisib,copanlisib, and idelalisib, while febrile neutropenia was prevalent amongcopanlisib, duvelisib, and idelalisib. Intestinal perforation was solelyassociated with alpelisib.
UNASSIGNED: The safety profiles of the five PI3K inhibitorsvary concerning adverse events. These findings could guide drug selection andinform future prospective research.

UNASSIGNED: Fostamatinib, an FDA-approved oral small-molecule spleen tyrosine kinase (SYK) inhibitor, is used to treat thrombocytopenia in adults with chronic immune thrombocytopenia (ITP) who have not responded to previous treatments. However, comprehensive safety data is lacking. This study uses the FDA Adverse Event Reporting System (FAERS) database to explore real-world adverse events (AEs) related to fostamatinib, aiming to inform its clinical use.
UNASSIGNED: The FAERS database was retrospectively queried to extract reports associated with fostamatinib from 2019 to 2023. To identify and evaluate potential AEs in patients receiving fostamatinib, various disproportionality analyses such as the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN), and the multi-item gamma Poisson shrinker (MGPS) were employed.
UNASSIGNED: A total of 23 AE signals were included in our analysis. Among them, hypertension, blood pressure increase, blood pressure abnormality, hepatic enzyme increase, and diarrhea were consistent with the common AEs described for fostamatinib in clinical trials. In addition, unexpected serious AEs were detected including cerebral thrombosis and necrotizing soft tissue infection. The median time to onset of fostamatinib-related AEs was 86 days.
UNASSIGNED: Our investigation revealed several possibly emergent safety concerns associated with fostamatinib in real-world clinical practice, which might provide essential vigilance evidence for clinicians and pharmacists to manage the safety issues of fostamatinib.
