Exploring SGLT-2 inhibitors and sarcopenia in FAERS: a post-marketing surveillance study

ABSTRACT Background The sodium-dependent glucose transporters 2 inhibitors (SGLT-2i) is associated with body weight loss but the composition of the losing weight remains unclear. Research design and methods Disproportionality analyses, including 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) algorithms, were employed to quantify the signals of SGLT-2i-associated musculoskeletal and connective tissue disorders AEs. Results The search retrieved a total of 3,206 cases of musculoskeletal and connective tissue disorder-related AEs during the reporting period. This included 1,061 cases for Canagliflozin, 1,052 cases for Dapagliflozin, 1,074 cases for Empagliflozin, and 19 cases for Ertugliflozin. Fifteen preferred terms (PTs) with significant disproportionality were retained. No musculoskeletal and connective tissue system-related AE signals were reported for Ertugliflozin. We identified a risk of muscle necrosis with Canagliflozin use, a risk of sarcopenia with Dapagliflozin use, and a chance of muscle atrophy with Dapagliflozin and Empagliflozin prescriptions. Most cases occurred within the first month after SGLT-2i initiation, and AEs can persist beyond 360 days of use. Conclusions Our study identified potential new musculoskeletal and connective tissue disorder-related AE signals associated with SGLT-2 inhibitors.

A disproportionality analysis of antipsychotic-induced hyperprolactinemia based on FDA adverse event reporting system.

This study aims to compare the risks of different antipsychotics in causing hyperprolactinemia, taking into account the age, gender, and onset time. We searched the FDA Adverse Event Reporting System (FAERS) from January 1, 2004, to March 31, 2022, for reports of hyperprolactinemia treated with antipsychotics. We evaluated the association between antipsychotics and the risk of hyperprolactinemia using reporting odds ratio (ROR) based on a disproportionality analysis. Moreover, information regarding age, gender, countries, and onset time was collected. We found 4,430 reports of antipsychotic-induced hyperprolactinemia involving 13 different antipsychotics. From highest to lowest ROR value, the top five antipsychotics were as follows: risperidone (ROR = 631.0611; 95% CI: 592.7329, 671.8677) > amisulpride (ROR = 59.4425; 95% CI: 19.0668, 185.317) > paliperidone (ROR = 31.9885, 95% CI: 27.912, 36.6604) > fluphenazine (ROR = 15.6026; 95% CI: 5.0236, 48.4595) > haloperidol (ROR = 14.3861; 95% CI: 11.173, 18.5231). Except for three drugs (risperidone, haloperidol, and amisulpride), women outnumbered men in cases of antipsychotic-induced hyperprolactinemia. The age range was 13-64 years old, with the most being 19-44 years old, followed by 45-64 years old, and there were fewer elderly patients. From longest to shortest, the median onset time of these antipsychotics was as follows: cariprazine (305 days) > risperidone (304 days) > quetiapine (276 days) > haloperidol (183 days) > ziprasidone (54 days) > lurasidone (44.5 days) > olanzapine (41 days) > asenapine (15.5 days) > paliperidone (15 days) > aripiprazole (12 days) > clozapine (6 days). Risperidone had the greatest risk of increasing prolactin, whereas clozapine had the lowest. Antipsychotic-induced hyperprolactinemia was more common in women and middle-aged patients. Clozapine had the shortest onset time in raising prolactin, whereas cariprazine had the longest.

Drug-associated congenital anomalies of the external ear identified in the United States food and drug administration adverse event reporting system database

Congenital anomalies of the external ear can have a significant impact on a child’s development and quality of life. While genetic factors play a crucial role in the etiology of these anomalies, environmental factors such as drug exposure during pregnancy may also contribute to their occurrence. This study aims to investigate the association between drug exposure and congenital anomalies of the external ear using data from an adverse drug reaction report database. Using OpenVigil 2.1, we queried the FAERS database to retrieve adverse event reports from the first quarter of 2004 to the first quarter of 2024. To identify relevant cases, we used Medical Dictionary for Regulatory Activities terms focusing on congenital anomalies of the external ear. Drug generic names were sourced from the DrugBank database. To assess safety signals and rank drugs by their signal strength, we conducted a disproportionality analysis, generating reporting odds ratios (ROR) and proportional reporting ratios (PRR). A total of 20,754,281 AE reports were identified in the FAERS database from Q1 2004 to Q1 2024, of which 1763 were related to congenital anomalies of the external ear. Valproic acid (122 cases) was associated with the most cases, followed by mycophenolate mofetil (105 cases) and lamotrigine (65 cases). According to the disproportionality analysis, the top five drugs with the highest ROR and PRR were primidone (ROR: 397.05, 95% CI 147.21, 1070.9; PRR: 388.71, 95% CI 145.89, 1035.7), valproic acid (ROR: 239.46, 95% CI 123.75, 463.37; PRR: 236.42, 95% CI 123.82, 451.43), tapazole (ROR: 198.35, 95% CI 63.49, 619.67; PRR: 196.25, 95% CI 62.97, 611.67), nevirapine (ROR: 138.24, 95% CI 82.9, 230.51; PRR: 137.23, 95% CI 82.44, 228.44), and sebivo (ROR: 117.1, 95% CI 48.51, 282.67; PRR: 116.37, 95% CI 48.17, 281.12). This study identified several drugs significantly associated with congenital anomalies of the external ear in the FAERS database using disproportionality analysis. The findings can help healthcare professionals better recognize and manage drug-induced congenital anomalies of the external ear, particularly when prescribing high-risk medications. Further research is needed to elucidate the mechanisms underlying these associations and develop strategies for preventing and mitigating drug-induced congenital anomalies of the external ear.

Social Determinants of Health and Risk-Adjusted Sepsis Mortality in the Nationwide Veterans Affairs Healthcare System.

Traditional risk prediction and risk adjustment models have focused on clinical characteristics, but accounting for social determinants of health (SDOH) and complex health conditions could improve understanding of sepsis outcomes and our ability to predict outcomes, treat patients, and assess quality of care. To evaluate the impact of SDOH and health scales in sepsis mortality risk prediction and hospital performance assessment. Observational cohort study. One hundred twenty-nine hospitals in the nationwide Veterans Affairs (VA) Healthcare System between 2017 and 2021. Veterans admitted through emergency departments with community-acquired sepsis. Individual- and community-level SDOH (race, housing instability, marital status, Area Deprivation Index [ADI], and rural residence) and two health scales (the Care Assessment Need [CAN] score and Claims-Based Frailty Index [CFI]). The primary outcome was 90-day mortality from emergency department arrival; secondary outcomes included 30-day mortality and in-hospital mortality. Among 144,889 patients admitted to the hospital with community-acquired sepsis, 139,080 were men (96.0%), median (IQR) age was 71 (64-77) years, and median (IQR) ADI was 60 (38-81). Multivariable regression models had good calibration and discrimination across models that adjusted for different sets of variables (e.g., AUROC, 0.782; Brier score, 1.33; and standardized mortality rate, 1.00). Risk-adjusted hospital performance was similar across all models. Among 129 VA hospitals, three hospitals shifted from the lowest or highest quintile of performance when comparing models that excluded SDOH to models that adjusted for all variables. Models that adjusted for ADI reported odds ratios (CI) of 1.00 (1.00-1.00), indicating that ADI does not significantly predict sepsis mortality in this cohort of patients. In patients with community-acquired sepsis, adjusting for community SDOH variables such as ADI did not improve 90-day sepsis mortality predictions in mortality models and did not substantively alter hospital performance within the VA Healthcare System. Understanding the role of SDOH in risk prediction and risk adjustment models is vital because it could prevent hospitals from being negatively evaluated for treating less advantaged patients. However, we found that in VA hospitals, the potential impact of SDOH on 90-day sepsis mortality was minimal.

Plasma levels of polyunsaturated fatty acids and multiple sclerosis susceptibility in a US case-control study

BackgroundThere are plausible mechanisms, yet mixed evidence, that higher polyunsaturated fatty acids (PUFAs) levels reduces the risk of multiple sclerosis (MS). Prior studies relied on dietary surveys to estimate levels. ObjectiveWe tested associations between plasma levels of n-3 and n-6 PUFAs and likelihood of MS onset or clinically isolated syndrome (CIS) using data from the MS Sunshine Study, a case-control study conducted in the United States. MethodsCase participants (n = 589) aged ≥ 18 years and matched control participants (n = 630) were recruited between 2011 and 2015. Plasma phospholipid fatty acid profiling was conducted by gas-liquid chromatography. We used logistic regression to report odds ratios, testing for interactions, adjusting for covariates and correcting for multiple comparisons. ResultsThere was a 6 % lower probability of MS/CIS per unit increase in total n-6 PUFA level, expressed as a percentage of total plasma phospholipid fatty acids (odds ratio = 0.94; 95 % confidence interval = 0.90,0.98; p = 0.012). We found no statistically significant association between individual or total plasma levels of n-3 PUFAs and probability of MS/CIS; however, plasma levels of n-3 PUFAs were low across the cohort. No other individual or aggregate PUFA levels were significantly associated with MS/CIS. ConclusionA higher total n-6 PUFA level may be beneficial in terms of MS susceptibility.Further research is needed to determine whether n-3 PUFAs may be beneficial only above a threshold that is achievable by supplementation.

A real-world pharmacovigilance study using disproportionality analysis of United States Food and Drug Administration Adverse Event Reporting System events for vinca alkaloids: comparing vinorelbine and Vincristine

ABSTRACT 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.

Adverse Event Profile of First-line Drugs for Treating Patent Ductus Arteriosus in Neonates: A Disproportionality Analysis Study of USFDA Adverse Event Reporting System.

Acetaminophen, ibuprofen, and indomethacin are widely used as first-line drugs for patent ductus arteriosus (PDA) closure in preterm neonates. However, their relative safety profiles remain unclear. Adverse event reports related to the first-line drugs used in PDA and neonates in general were retrieved from the US Food and Drug Authority (FDA) Adverse Event Reporting System. Deduplicated reports were analyzed using proportional reporting ratios and reporting odds ratios to identify disproportionality safety signals between drugs. A total of 969 unique reports related to the first-line drugs used in PDA and 499 reports in the neonatal period were included. Acetaminophen signals primarily involved the liver, while ibuprofen and indomethacin signals pertained to gastrointestinal, renal, vascular, and mortality outcomes. Higher occurrences of death were reported with indomethacin and ibuprofen compared with acetaminophen. This first comparison of PDA drug safety profiles from spontaneous reports highlights some differences, with acetaminophen potentially conferring a safer adverse effect profile overall. While limitations include missing data and reporting biases, the signals warrant further validation. Given its comparable efficacy to ibuprofen, as demonstrated in other studies, acetaminophen has the potential to be preferred as an initial medical therapy for PDA.

Global and Regional Burden of Vaccine-Associated Erythema Multiforme and their Related Vaccines, 1967-2023: An In-Depth Analysis of the World Health Organization Pharmacovigilance Database.

Vaccine-associated erythema multiforme (EM) remains under-researched, impacting global vaccine safety evaluations. This study examines the global and regional burden of EM and its association with specific vaccines to optimize vaccination strategies. We analyzed data from the WHO pharmacovigilance database on vaccine-associated EM from 1967 to 2023 (n=131,255,418 reports). Reporting frequencies, reported odds ratios (ROR), and information components (IC) were calculated for 16 vaccines across 170 countries. We identified 6,355 cases (males, n=3,182 [50.07%]) of vaccine-associated EM from a total of 46,378 reports of all-cause EM. While vaccine-associated EM has been consistently reported, there has been a notable increase in reported incidence particularly in 2010 and 2020. Measles, mumps, and rubella vaccines had the highest association with vaccine-associated EM reports (ROR, 8.75 [95% confidence interval (CI), 8.11-9.44]; IC, 3.10 [IC0.25, 2.97]), followed by hepatitis B (8.54 [7.66-9.51]; 3.06 [2.88]), hepatitis A (8.11 [7.01-9.39]; 2.98 [2.74]), typhoid (6.50 [4.75-8.90]; 2.60 [2.07]), encephalitis (5.86 [4.35-7.91]; 2.47 [1.96]), diphtheria, tetanus toxoids, pertussis, polio, and Hemophilus influenza type b (5.70 [5.42-5.99]; 2.46 [2.38]), pneumococcal (5.56 [5.11-6.06]; 2.45 [2.31]), rotavirus (4.96 [4.21-5.84]; 2.29 [2.01]), varicella-zoster (4.44 [3.99-4.95]; 2.13 [1.95]).Vaccine-associated EM reports were more strongly correlated with younger age groups and males. The overall fatality rate of vaccine-associated EM was 0.04%. The rise in vaccine-associated EM across multiple vaccines, especially in younger populations, highlights the need for closer monitoring and more informed vaccination practices to mitigate adverse reactions.

β-Blockers and Asthma: Surprising Findings from the FAERS Database

Introductionβ-Blockers are essential for cardiovascular disease management but can induce respiratory issues, particularly with non-selective β-blockers. Their safety in asthmatic patients is debated. ObjectiveThis study investigates the link between different classes of β-blockers and the risk of asthma and asthma-like adverse events (AEs) using data from the Food and Drug Administration’s Adverse Event Reporting System (FAERS). MethodsAsthma-related AEs linked to β-blockers were analyzed from the FAERS database. The risk associated with different β-blocker classes was evaluated through disproportionality analysis using the reporting odds ratio (ROR). ResultsAmong 251,145 AEs reported for β-blockers, 4,104 were asthma-related. Selective β1-blockers had a higher asthma risk signal (ROR: 1.15) compared to non-selective β-blockers (ROR: 0.90). Dual α- and β-blockers showed the lowest risk (ROR: 0.51). The Vashistha and Kumar classification detailed risk profiles for various β-blockers, highlighting differences even within the same class. Dual α- and β-blockers, hydrophilic, and lipophilic β-blockers posed lower asthma risks, while selective β1-blockers had higher risks regardless of intrinsic sympathomimetic activity. ConclusionRisk stratification underscores the need for cautious β-blocker selection in asthmatic patients or those predisposed to asthma. The study highlights significant variability in risk among different β-blocker classes, crucial for clinical decisions and patient outcomes. Drugs like esmolol, metoprolol, nebivolol, and nadolol may be safer for asthmatic patients, whereas betaxolol, bisoprolol, timolol, and propranolol should be avoided. Regular respiratory monitoring is crucial for asthmatic patients on β-blockers, starting treatment at low doses and adjusting to minimize bronchoconstriction risk.

Ischemic cardiopathy induced by capecitabine in gastric cancer: The role of dihydropyrimidine dehydrogenase metabolites

Fluoropyrimidine-based therapies, 5-fluorouracil (5-FU) and its oral prodrugs, capecitabine and tegafur/oteracil/gimeracil (S-1), are pivotal drugs to treat gastric cancer. Fluoropyrimidines are associated with cardiotoxicity including ischemic cardiopathy. The mechanisms of ischemic cardiopathy are considered to be multifactorial, potentially involving metabolites of 5-FU generated by the dihydropyrimidine dehydrogenase (DPD). By using Vigibase®, the World Health Organization pharmacovigilance database, we aimed to investigate the implication of the 5-FU metabolites induced by DPD in the occurrence of ischemic cardiopathy in patients with gastric cancer using capecitabine. In Vigibase®, we included serious reports of ischemic cardiopathy with capecitabine and S-1 from January 1st, 2013, to September 16th, 2023. Among patients with gastric cancer, we calculated the reporting odds ratio (ROR) of ischemic cardiopathy to compare capecitabine (a prodrug without DPD antagonist) with S-1 (a prodrug associated with a DPD antagonist). The ROR was also calculated regardless of the drug indication. An ancillary analysis based on the French pharmacovigilance database was also performed. We evaluated the ROR of serious cardiac disorders induced by 5-FU intravenous infusion according to the DPD status (no deficiency versus complete or partial deficiency). In gastric cancer, 1843reports (including 23 ischemic cardiopathy) for capecitabine and 2225reports (including 17 ischemic cardiopathy) for S-1 were included. Median time-to-onset was 7 (3-26) days for capecitabine and 22 (13.25-30) days for S-1. Capecitabine was associated with an increased ROR of ischemic cardiopathy compared with S-1 in gastric cancer (ROR=1.6; [95% CI=1.5-1.8]) and regardless of the indication (7.3; [95% CI=6.6-8.0]). In the ancillary analysis, among 5-FU users, the lack of DPD deficiency increased the ROR for cardiac disorders (2.1; [95% CI=1.9-2.3]) compared to the DPD deficiency. This work supports the role of toxic 5-FU metabolites generated by dihydropyrimidine dehydrogenase in the occurrence of ischemic cardiopathy among patients with gastric cancer using capecitabine.

Association of incretin-based therapies with hepatobiliary disorders among patients with type 2 diabetes: a case series from the FDA adverse event reporting system.

Incretin therapies, including dipeptidyl peptidase-4 inhibitors (DPP-4is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs), are crucial for type 2 diabetes treatment. Evidence on their association with gallbladder, biliary diseases and liver injury remains inconsistent. This study evaluated the association between incretin therapies and hepatobiliary adverse events using FDA's Adverse Event Reporting System (FAERS) data. Case reports involving incretin therapies and hepatobiliary events from January 2006 to December 2023 were extracted from FAERS. The association between these agents and hepatobiliary adverse events (hAEs) was analyzed using reporting odds ratios and empirical Bayesian geometric means. Descriptive analyses were conducted to characterize the demographic and clinical features of the hAE cases. Additionally, subgroup analyses calculated reporting odds ratios to evaluate the strength of association between specific incretin drugs and hAEs. Among 68,351 case reports associated with incretin-based therapies, 1,327 (1.941%) involved hepatobiliary adverse events. DPP-4 inhibitors demonstrated statistically significant associations with multiple hepatobiliary events like cholelithiasis, cholecystitis chronic, and biliary diseases. In contrast, GLP-1 receptor agonists showed weaker associations, primarily linked to gallbladder and biliary disease risks. Subgroup analyses revealed stronger positive correlations with hepatobiliary events for liraglutide and semaglutide among GLP-1 agonists, and for sitagliptin, linagliptin, and vildagliptin among DPP-4 inhibitors. The pooled reporting odds ratio of 2.85 indicated a positive correlation between these drugs and studied adverse events. This study found statistically significant associations between DPP-4 inhibitors and hepatobiliary adverse events like cholelithiasis and cholecystitis. GLP-1 agonists showed weaker gallbladder/biliary disorder links but higher acute cholecystitis risk. Subgroup analyses revealed varying correlations among specific drugs, potentially dose-dependent. Further large-scale studies are needed to evaluate class effect differences and elucidate mechanisms for guiding clinical use.

Suicidal behaviour and CFTR modulators: A case series and WHO database disproportionality analysis

BackgroundA highly effective therapy involving elexacaftor, tezacaftor, and ivacaftor (ETI) for cystic fibrosis (CF) patients has recently raised safety concerns regarding potential psychiatric disorders. The manuscript reports cases of suicide attempts in patients receiving ETI and investigates putative causality using the WHO spontaneous reporting database. MethodsFirst, four cases of suicide attempts/self-injury are described. Second, a disproportionality analysis was conducted using spontaneous reports collected in Vigibase through the standardised MedDRA Query (narrow version) "Suicide/Self-injury" and ETI exposure. Reporting Odds Ratio (ROR) was calculated for the main and subgroup (i/suicide attempt, ii/suicidal ideation) analyses. Sensitivity analyses were performed with variations in exposure, to ivacaftor/lumacaftor to assess the intrinsic psychiatric risk of CF patients, and paracetamol as a positive control for suicide attempt and a negative one for suicidal ideation. Exposure to reduced-dose ETI was studied to evaluate the dose-gradient effect. ResultsFour cases of suicide attempt/self-injury occurred 3 to 13 months after ETI initiation in CF patients and were reported to the Bordeaux Pharmacovigilance centre. Aside, in Vigibase, ETI is associated with an increased likelihood of reporting suicidal behaviour (ROR 2.5, 95 % CI[2.1; 2.8]). A signal of disproportionate reporting was found for the subgroup of suicide attempts (1.4, 95 % CI[1.2; 1.8]), unlike ivacaftor/lumacaftor, which was associated only with the risk of reporting suicidal ideation. Significant ROR values were also found for reduced-dose ETI for all psychiatric effects studied except suicide attempt. ConclusionsETI exposure is related with increased reporting of suicidal behaviour. A potential dose-dependent effect merits further investigation.

Unraveling the Spectrum of Ocular Toxicity with Oxaliplatin: Clinical Feature Analysis of Cases and Pharmacovigilance Assessment of the US Food and Drug Administration Adverse Event Reporting System Database

Ocular adverse events (oAEs) are a class of adverse events associated with oxaliplatin that are realistically observed in real-world settings. Herein, we aim to describe the clinical characteristics of oAEs associated with oxaliplatin through a systematic review of case reports and to assess a potential safety signal. PubMed, Embase, and Cochrane Library databases were used to retrieve case reports. The global disproportionality study was performed leveraging the US Food and Drug Administration Adverse Event Reporting System database from January 2004 to September 2023. Bayesian information component (IC) and reporting odds ratio (ROR) were applied to identify and evaluate potential oAEs associated oxaliplatin. A total of 20 cases from the systematic case review (of 13 screened articles) were reported on oAEs associated with oxaliplatin, with ages between 26 and 76 years. Therein, 16 (84.2%) cases described loss of vision, and the remaining cases presented with bilateral blepharoptosis, papilledema, and optic disc swelling. Insights from the US Food and Drug Administration Adverse Event Reporting System database showed that oAEs accounted for 4.28% (n = 1194) of the overall oxaliplatin-related adverse event reports, of which 1140 (95.48%) had a serious outcome. The median (interquartile range) onset time of oAEs with oxaliplatin was day 1 (0-25; n = 649). Disproportionality analysis revealed that ocular injuries NEC (n = 28, ROR, 22.72; lower limit of the 95% 2-sided CI for IC, 3.12) was the most significant signals detected. Additionally, unexpected significant oAEs, including eyelid ptosis, eyelid edema, eye movement disorder, blepharospasm, periorbital edema, swelling of eyelid, ophthalmoplegia, retinal vein thrombosis, cataract nuclear, blindness cortical, cataract subcapsular, and lacrimation disorder, were also reported disproportionality. Our study systematically described the characteristics and outcomes of oxaliplatin-related ocular toxicity and also uncovered potential oAEs that were not disclosed in the package insert. Further prospective epidemiologic studies to validate these findings are warranted.

A Real-World Study on Adverse Reactions of Belimumab Based on the FDA Adverse Event Reporting System Database.

This investigation leverages data derived from the United States Food and Drug Administration Adverse Event Reporting (FAERS) to real-world adverse reactions associated with Belimumab, with the intention of providing guidance for safe clinical pharmacotherapy. Data encompassing adverse drug event (ADE) reports relating to Belimumab from Q1 2011 to Q4 2023 within the FAERS were extracted and analyzed using methodologies such as the reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN), and Multi-item Gamma Poisson Shrinker (MGPS). The study identified a total of 19 825 ADE reports where Belimumab was the primary suspect medication, with the United States constituting the majority of reporting countries (16 312 cases, or 82.28%). Patients aged 18 to 64.9 years accounted for the largest demographic (36.29%), while the proportion of female patients (77.91%) significantly surpassed that of male patients (5.03%). The analysis uncovered 184 unique Preferred Terms (PTs) across 21 System Organ Classes (SOCs). Following selection through ROR, the SOC signal strength was prioritized as follows: Systemic disorders and administration site conditions, infections and infestations, a variety of musculoskeletal and connective tissue disorders, and conditions related to pregnancy, puerperium, and the perinatal period. The top five PTs for ADE reports not included in the product's labeling were hypersensitivity reactions, immunosuppression, non-vascular diseases, herpes virus infections, and Sjögren's syndrome. The top five PTs for ADE signal strength not included in the labeling were disseminated cutaneous herpes zoster, herpes zoster meningitis, onycholysis, cyclothymic disorder, and mixed connective tissue disease. Based on pharmacovigilance research utilizing the FAERS database, it is recommended that clinical monitoring of Bevacizumab should be intensified to support effective pharmaceutical care and ensure rational clinical medication use.

Adverse Event Assessment of Upadacitinib: A Pharmacovigilance Study Based on the FAERS Database.

Upadacitinib, a Janus kinase (JAK) inhibitor, has been approved by the FDA to treat various autoimmune conditions. This study assessed its adverse events by analyzing reports from the FDA Adverse Event Reporting System (FAERS). FAERS data from Q3 2019 to Q4 2023 were extracted, and disproportionality analyses were conducted using four statistical measures, reporting odds ratio, proportionate reporting ratio, Bayesian confidence propagation neural network, and empirical Bayesian geometric mean. A total of 6 879 398 adverse event reports were collected, with 37 700 reports identifying upadacitinib as the "primary suspected." These reports involved 24 system organ classes and 246 preferred terms that met the criteria across all four algorithms. The distribution of adverse events was assessed separately for female and male patients. Further analysis of the top 25 preferred terms revealed that, although the system organ classes were similar between sexes, the specific adverse events differed. The adverse events were analyzed by gender, showing musculoskeletal and skin disorders were prevalent and severe in male patients, while musculoskeletal issues, infections, and abnormal laboratory tests were common in female patients. Unexpected events like trigger finger, biliary sepsis, and serious events such as oral neoplasm were also identified. This study provides real-world evidence for the safety evaluation of upadacitinib and underscores the need to monitor sex-specific adverse events. Future prospective studies are necessary to confirm these pharmacovigilance findings.

The pharmacogenomic and immune landscape of snoRNAs in human cancers

Small nucleolar RNAs (snoRNAs) are a class of non-coding RNAs primarily known for their role in the chemical modification of other RNAs. Recent studies suggested that snoRNAs may play a broader role in anti-cancer treatments such as targeted therapies and immunotherapies. Despite these insights, the comprehensive landscape of snoRNA associations with drug response and immunotherapy outcomes remains unexplored. In this study, we identified 79,448 and 75,185 associations between snoRNAs and drug response using data from VAEN and CancerRxTissue, respectively. Additionally, we discovered 29,199 associations between snoRNAs and immune checkpoint genes and 47,194 associations between snoRNAs and immune cell infiltrations. Sixteen snoRNAs were significantly correlated with immunotherapy objective response rate (ORR), and 92 snoRNAs showed significantly differential expression between cancers with high and low ORR. Furthermore, we identified 17 snoRNAs with significantly differential expression between cancer types with high and low immune-related adverse event (irAE) reporting odds ratio (ROR). Several snoRNAs, such as SNORD92, and SNORD83B, may represent promising biomarkers or therapeutic targets that needs further investigation. To facilitate further research, we developed a user-friendly portal, Pharmacogenomic and Immune Landscape of SnoRNA (PISNO, https://hanlaboratory.com/PISNO/), enabling researchers to visualize, browse, and download multi-dimensional data. This study highlights the potential of snoRNAs as biomarkers or therapeutic targets, paving the way for more effective and personalized anti-cancer treatments.

Association Between Sex, Race, and Ethnicity and IVSedation Use in Patients Receiving Invasive Ventilation

BackgroundIntravenous sedation is an important tool for managing invasively ventilated patients, yet excess sedation is harmful, and dosing could be influenced by implicit bias. Research questionWhat is the association between sex, race and ethnicity, and sedation practices? MethodsWe performed a retrospective single-center cohort study of adults receiving invasive ventilation for 24 hours or more using the MIMIC-IV (2008-2019) database from Boston, USA. We used a repeated-measures design (4-hour intervals) to study the association between sex (female, male) or race and ethnicity (Asian, Black, Hispanic, White) and sedation outcomes. Sedation outcomes included sedative use (propofol, benzodiazepine, dexmedetomidine) and minimum sedation score. We categorized sedative use as follows: no sedative, then lowest, second, third, and highest quartiles of sedative dose. We adjusted for covariates with multilevel Bayesian proportional odds modeling and reported odds ratios (OR) with 95% credible intervals (CrI). ResultsWe studied 6,764 patients: 43% female; 3.5% Asian, 12% Black, 4.5% Hispanic and 80% White. Benzodiazepines were administered to 2,334 (36%) patients. Black patients received benzodiazepines less often and at lower doses than White patients (OR for more benzodiazepine 0.66, CrI 0.49-0.92). Propofol was administered to 3,865 (57%) patients. Female patients received propofol less often and at lower doses than male patients (OR for more propofol 0.72, CrI 0.61-0.86). Dexmedetomidine was administered to 1,439 (21%) patients, and use was similar across sex or race and ethnicity. Female patients were less sedated than male patients (OR for deeper sedation 0.71, CrI 0.62 to 0.81), and Black patients were more sedated than White patients (OR for more sedated 1.28, CrI 1.05 to 1.55). InterpretationAmong patients invasively ventilated for at least 24 hours, intravenous sedation and attained sedation levels varied by sex and race and ethnicity. Adherence to sedation guidelines may improve equity in sedation management for critically ill patients.

Influence of loop diuretics on denosumab-induced hypocalcaemia in osteoporosis: a retrospective observational analysis

BackgroundWe examined whether denosumab-induced hypocalcaemia is evident in osteoporosis when given loop diuretics that promote urinary calcium excretion.MethodsJapanese Spontaneous Adverse Drug Event Reports was analyzed to examine signals for denosumab-induced hypocalcaemia co-administered loop diuretics. We retrospectively included osteoporotic patients to detect predictors for denosumab-induced hypocalcaemia (corrected calcium level < 8.5 mg/dL) using multivariate logistic regression analysis. We compared differences in corrected calcium levels (ΔCa = nadir-baseline).ResultsA significant signal for hypocalcaemia was detected (Reporting odds ratio = 865.8, 95% confidence interval [95% CI]: 596.8 to 1255.9, p < 0.0001). Among 164 patients (hypocalcaemia, 12%), loop diuretics have a significant association with hypocalcaemia (odds ratio [OR] = 6.410, 95% CI: 1.005 to 40.90, p = 0.0494). However, hypocalcaemia was found to be lower in high corrected calcium levels at baseline (OR = 0.032, 95% CI: 0.005 to 0.209, p < 0.0001) and calcium and vitamin D supplementation (OR = 0.285, 95% CI: 0.094 to 0.868, p = 0.0270). In the non-hypocalcaemia, ΔCa decreased significantly in the denosumab plus loop diuretics than in the denosumab alone (-0.9 [-1.3 to -0.7] mg/dL vs. -0.5 [-0.8 to -0.3] mg/dL, p = 0.0156). However, ΔCa remained comparable in the hypocalcaemia despite loop diuretics co-administration (-1.0 [-1.2 to -0.8] mg/dL vs. -0.8 [-1.5 to -0.7] mg/dL, p = 0.7904).ConclusionsLoop diuretics may predispose to developing denosumab-induced hypocalcaemia.

Adverse reactions of immune checkpoint inhibitors combined with Proton pump inhibitors: a pharmacovigilance analysis of drug-drug interactions

BackgroundCombining immune checkpoint and proton pump inhibitors is widely used in cancer treatment. However, the drug-drug interactions of these substances are currently unknown. This study aimed to explore drug-drug interactions associated with concomitant immune checkpoint and proton pump inhibitors.MethodsData were obtained from the US Food and Drug Administration Adverse Event Reporting System from 2014 to 2023. Disproportionality analysis was used for data mining by calculating the reporting odds ratios (RORs) with 95% confidence intervals (95%Cls). The adjusted RORs (RORadj) were then analysed using logistic regression analysis, considering age, sex, and reporting year. Drug-drug interactions occur when a combination treatment enhances the frequency of an event. Further confirmation of the robustness of the findings was achieved using additive and multiplicative models, which are the two statistical methodologies for signal detection of DDIs using spontaneous reporting system.ResultsThe total number of reports on immune checkpoint combined with proton pump inhibitors was 4,276. Median patient age was 66 years (interquartile range [IQR]: 60–74 years). Significant interaction signals were observed for congenital, familial and genetic disorders (RORadj = 2.66, 95%CI, 1.38–5.14, additive models = 0.7322, multiplicative models = 3.5142), hepatobiliary disorders (RORcrude = 6.64, 95%CI, 5.82–7.58, RORadj = 7.10, 95%CI, 6.16–8.18, additive models = 2.0525, multiplicative models = 1.1622), metabolism and nutrition disorders (RORcrude = 3.27, 95%CI, 2.90–3.69, RORadj = 2.66, 95%CI, 2.30–3.08, additive models = 0.6194), and skin and subcutaneous tissue disorders (RORcrude = 1.41, 95%CI, 1.26–1.58, RORadj = 1.53, 95%CI, 1.34–1.75, additive models = 0.6927, multiplicative models = 5.3599). Subset data analysis showed that programmed death-1 combined with proton pump inhibitors was associated with congenital, familial, and genetic disorders; hepatobiliary disorders; and skin and subcutaneous tissue disorders. Programmed death ligand-1 combined with proton pump inhibitors was associated with adverse reactions of metabolism and nutrition disorders. Cytotoxic T-lymphocyte antigen-4 combined with proton pump inhibitors was associated with congenital, familial, and genetic disorders, and skin and subcutaneous tissue disorders.ConclusionsBased on real-world data, four Standardized MedDRA Query System Organ Class toxicities were identified as drug-drug interactions associated with combining immune checkpoint and proton pump inhibitors. Clinicians should be cautious when administering these drugs concomitantly. Preclinical trials and robust clinical studies are required to explore the mechanisms and relationships underlying interactions, thus improving understanding of drug-drug interactions associated with this combination therapy.

Safety assessment of Tafamidis: a real-world pharmacovigilance study of FDA adverse event reporting system (FAERS) events

ObjectiveTafamidis-associated adverse events (AEs) were investigated retrospectively by data mining the US Food and Drug Administration Adverse Event Reporting System (FAERS) to inform clinical safety.MethodsData were gathered from the FAERS database, which spans the second quarter of 2019 to the fourth quarter of 2023. A total number of 8532 reports of Tafamidis-related adverse events were detected after evaluating 8,432,351 data. Disproportionality analyses were used to quantify the signal and assess the significance of Tafamidis-associated AEs using four algorithms, including the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the multi-item gamma Poisson shrinker (MGPS) and the Bayesian confidence propagation neural network (BCPNN).ResultsAmong the 8532 reports of AEs with Tafamidis as the primary suspected drug, Tafamidis-induced AEs were identified as occurring in 27 system organ classes (SOC). A total of 207 Tafamidis-induced AEs were detected which simultaneously complied with the four algorithms. Our analysis also identified new adverse reactions including Hypoacusis, Deafness, and Essential hypertension. The median onset of adverse reactions associated with Tafamidis was 180 days (interquartile range [IQR] 51–419 days).ConclusionTafamidis is a drug that has shown favorable safety and tolerability results in clinical trials. However, a number of adverse reactions associated with Tafamidis have been identified through analysis of the FAERS database. In clinical applications, it is recommended to closely monitor patients’ hearing while using Tafamidis. In addition, it is hoped that further experimental and clinical studies will be conducted in the future to understand the mechanism of occurrence between Tafamidis and adverse reactions such as primary hypertension, hyperlipidemia, and height reduction.
