RESUMO
Caplacizumab reduces the need for therapeutic plasma exchange (TPE) during treatment for thrombotic thrombocytopenic purpura (TTP), associates with fewer required TPE, and shortens hospital stay. It is therefore recommended as part of standard care. However, the treatment effects on hemostasis may complicate initial management. We present a case of a woman with immune-mediated TTP who developed an intrathoracic hemorrhage on caplacizumab treatment after replacement of her central venous catheter. Reduced von Willebrand factor (vWF):glycoprotein Ib mutant (GPIbM) activity was reversed using vWF concentrate and the bleeding stopped. Unfortunately, vWF substitution in combination with caplacizumab discontinuation likely contributed to subsequent extensive venous thromboembolism. Risk-reducing strategies against both bleeding and thrombosis are crucial during caplacizumab treatment, and emergency vWF substitution increases the already high risk of thrombosis associated with TPE.
RESUMO
Background: Prolonged or excessive use of acid suppressants may increase the risk of Clostridioides difficile infection (CDI) by altering the intestinal microecosystem. Vonoprazan, a novel potassium-competitive acid blocker, exhibits a faster and more sustained acid-suppressive effect than proton pump inhibitors (PPIs). Therefore, vonoprazan may have a greater impact on the gut microbiota, potentially resulting in CDI. Objectives: This study aimed to explore the potential relationship between acid suppressants and CDI by the Japan Adverse Drug Event Report (JADER) and the FDA Adverse Event Reporting System (FAERS) databases. Design: A retrospective analysis of the JADER and FAERS databases was examined by disproportionality analysis. Methods: We performed signal detection analyses of CDI induced by vonoprazan and PPIs using the JADER and FAERS databases. The association between acid suppressants and CDI was calculated using the reporting odds ratio (ROR) and corresponding 95% confidence interval (95% CI). When the lower limit of the 95% CI is exceeded by 1, the association is considered statistically significant. Results: In the JADER database, the ROR (95% CI) for vonoprazan and PPIs based on suspect drug reports was 15.84 (12.23-20.50) and 2.51 (1.92-3.28), respectively. In the FAERS database, the ROR (95% CI) for vonoprazan and PPIs based on primary and secondary suspect drug reports was 11.50 (6.36-20.82) and 1.42 (1.34-1.51), respectively. Subgroup analysis showed that elderly patients aged 60 years and older were more strongly associated with CDI. The ROR (95% CI) for vonoprazan and PPIs in patients aged 60 years and older in the JADER database was 15.35 (11.59-20.33) and 1.65 (1.14-2.39), respectively. Similarly, the ROR (95% CI) for vonoprazan and PPIs in the FAERS database was 12.56 (6.26-25.20) and 1.43 (1.31-1.57), respectively. Excluding the effect of Helicobacter pylori (H. pylori) infection, the use of acid suppressants was still associated with CDI. Conclusion: While signal detection analysis based on the JADER and FAERS databases could not establish causality, our study demonstrated that both vonoprazan and PPIs were significantly associated with CDI. Vonoprazan showed a stronger association with CDI in both databases.
Introduction: Vonoprazan is a new type of acid suppressant, which has a stronger effect on acid inhibition than traditional proton pump inhibitors (PPIs). Vonoprazan may have a greater impact on the gut microbiota, which may increase the risk of Clostridioides difficile infection (CDI). The FDA created the FDA Adverse Event Reporting System (FAERS) database to support the post-market surveillance program. The PMDA created the Japan Adverse Drug Reaction Event Report (JADER) database to specifically collect adverse reaction reports in Japan. To further understand the potential relationship between acid suppressants and CDI, this study was analyzed using the JADER and FAERS databases. Methods: This study analyzed cases of CDI reported after the use of acid suppressants in the JADER and FAERS databases. Results: The analysis revealed that vonoprazan and PPIs are significantly associated with CDI in both databases. Notably, vonoprazan exhibited a stronger association compared to PPIs. Subgroup analysis indicated that this association was more pronounced in elderly patients aged 60 years and older. Additionally, excluding the influence of Helicobacter pylori (H. pylori) did not diminish the association between acid suppressants and CDI. Conclusion: Although signal detection analysis based on the JADER and FAERS databases could not establish causality, the results showed that both vonoprazan and PPIs were significantly associated with CDI. Vonoprazan was also more strongly associated with CDI than PPIs, which could be a potential safety concern, and further clinical studies are needed to confirm this finding.

RESUMO
BACKGROUND: The association between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccines and myocarditis/pericarditis in the Japanese population has not been systematically investigated. This study was aimed at clarifying the association between SARS-CoV-2 mRNA vaccines (BNT162b2 and mRNA-1273) and myocarditis/pericarditis as well as influencing factors by using the Japanese Adverse Drug Event Report database. METHODS: Reporting odds ratios (RORs) and 95 % confidence intervals (95 % CIs) for the association between the vaccines and myocarditis/pericarditis were calculated using data from the database (April 2004-December 2023). Age, sex, onset time, and outcomes in symptomatic patients were evaluated. RESULTS: The total number of reports was 880,999 (myocarditis: 1846; pericarditis: 761). The adverse events associated with the vaccines included myocarditis (919 cases) and pericarditis (321 cases), with the ROR [95 % CIs] being significant for both (myocarditis: 30.51 [27.82-33.45], pericarditis: 21.99 [19.03-25.40]). Furthermore, the ROR [95 % CIs] of BNT162b2 and mRNA-1273 were 15.64 [14.15-17.28] and 54.23 [48.13-61.10], respectively, for myocarditis, and 15.78 [13.52-18.42] and 27.03 [21.58-33.87], respectively, for pericarditis. Furthermore, most cases were ≤30 years or male. The period from vaccination to onset was ≤8 days, corresponding to early failure type based on analysis using the Weibull distribution. Outcomes were recovery or remission for most cases; however, they were severe or caused death in some cases. CONCLUSION: In the Japanese population, SARS-CoV-2 mRNA vaccination was significantly associated with the onset of myocarditis/pericarditis. The influencing factors included age of ≤30 years and male. Furthermore, although most adverse events occurred early after vaccination, overall outcomes were good.
RESUMO
Mycobacterium tuberculosis (TB) remains the leading cause of infection-related mortality worldwide. Drug resistance, need for multiple antimycobacterial agents, prolonged treatment courses, and medication-related side effects are complicating factors to TB cure. The introduction of treatment regimens containing the novel agents bedaquiline, pretomanid, and linezolid, with or without moxifloxacin (BPaL-M or BPaL, respectively) have substantially reduced TB-related morbidity and mortality and are associated with favorable rates of treatment completion and cure. This review summarizes key information on the pharmacology and treatment principles for moxifloxacin, bedaquiline, delamanid, pretomanid, linezolid, and tedizolid in the treatment of multi-drug resistant TB, with recommendations provided to address and attenuate common adverse effects during treatment.
RESUMO
Introduction: Although terlipressin is known to cause bradycardia, this adverse effect is usually described in association with hypertension and is considered a benign compensatory response mediated by arterial baroreceptors. Cardiac monitoring for patients receiving terlipressin is not routinely recommended. Case Presentation: A 77-year-old female patient with no history of coronary artery disease and no other coexisting risk factors for cardiac arrhythmias or conduction disturbances was admitted to intensive care unit with severe cholangitis, complicated by variceal bleeding. She developed severe sinus bradycardia following the use of terlipressin, which was associated with significant hypotension that required the infusion of norepinephrine. The bradycardia occurred again when terlipressin therapy was reattempted. Conclusion: Vasopressin is known to sensitize baroreceptor reflexes by a central mechanism though its actions on V1a receptors in the area postrema, and we speculate that vasopressin analogues such as terlipressin may act in the same manner. That this effect is not widely described in terlipressin safety literature may be due to the overall younger age range of the trial population. This raises the possibility that cardiac monitoring may be warranted for elderly patients receiving terlipressin.
RESUMO
BACKGROUND: Tofacitinib is one of the Janus kinase inhibitors approved for the treatment of rheumatoid arthritis. The major adverse event of this drug is herpes zoster, which can lead to death in severe cases. The risk of herpes zoster has been studied at 10 mg/day of tofacitinib; however, 5 mg/day, which is recommended in patients with chronic kidney disease, is unclear. OBJECTIVE: To investigate whether 5 mg/day of tofacitinib reduced the risk of herpes zoster compared with 10 mg/day in rheumatoid arthritis patients. METHODS: We analyzed the Japanese Adverse Drug Event Report Data (JADER) database and compared the frequency of herpes zoster in rheumatoid arthritis patients treated with tofacitinib 5 mg/day and 10 mg/day. Multivariable logistic regression analysis was performed to identify the risk factors for herpes zoster in tofacitinib users. RESULTS: A total of 812 tofacitinib users with rheumatoid arthritis were identified, including 131 with herpes zoster. Disproportionality for herpes zoster was observed between 5 mg/day and 10 mg/day (reporting odds ratio (OR): 0.68, 95% confidence interval (CI): 0.47-0.98, P = 0.045). Multivariable logistic regression analysis showed that the risk of herpes zoster was significantly increased in female patients (OR: 1.87, 95% CI: 1.12-3.12, P = 0.016) and methotrexate users (OR: 1.69, 95% CI: 1.12-2.54, P = 0.013) and significantly decreased with tofacitinib 5 mg/day compared with 10 mg/day (OR: 0.62, 95% CI: 0.40-0.96, P = 0.032). CONCLUSION: We suggest that tofacitinib 5 mg/day may decrease the risk of herpes zoster compared with 10 mg/day in rheumatoid arthritis patients.
RESUMO
BACKGROUND: Use of immune checkpoint inhibitors is growing, but clinical trial data may not apply to Indigenous patients or patients living in remote areas. AIMS: To provide real-world incidence of immune-related adverse events (irAE) in the Top End of the Northern Territory and compare incidence between demographic subgroups. METHODS: This retrospective, observational, cohort study collected data from electronic records of patients living in the Top End with solid organ cancer treated with immunotherapy between January 2016 and December 2021. The primary outcome was cumulative incidence of any-grade and severe irAE. Secondary outcomes were overall survival, treatment duration and reason for treatment discontinuation. RESULTS: Two hundred and twenty-six patients received immunotherapy. Forty-eight (21%) lived in a remote or very remote area, and 36 (16%) were Indigenous. Cumulative incidence of any-grade irAE was 54% (122/226 patients); incidence of severe irAE was 26% (59/226 patients). Rates were similar between Indigenous and non-Indigenous patients of any-grade (42% vs 56%, P = 0.11) and severe (11% vs 18%, P = 0.29) irAE. However, Indigenous patients had shorter treatment duration, more frequently discontinued treatment due to patient preference and appeared to have shorter median overall survival than non-Indigenous patients (17.1 vs 30.4 months; hazard ratio (HR) = 1.5, 95% confidence interval (CI) = 0.92-2.66). There was no difference in mortality between remote and urban patients (median overall survival 27.5 vs 30.2 months; HR = 1.1, 95% CI = 0.7-1.7). CONCLUSIONS: Rates of irAE in our cohort are comparable to those in the published literature. There was no significant difference in any-grade or severe irAE incidence observed between Indigenous and non-Indigenous patients.
RESUMO
Ketamine therapy can reduce the risk of suicide and depression in the treatment resistant patient. Adverse effects of ketamine infusion include blurred vision, nausea and vomiting, hepatotoxicity, headache, and cystitis. However, the effect of ketamine infusion on blood glucose remains unclear. This report describes several episodes of hypoglycemia in a 36-year-old man with type 1 diabetes mellitus after ketamine infusion for treatment-resistance depression. He has been receiving subcutaneous insulin injection and denied any severe hypoglycemia events in the prior 20 years. He had unsuccessful treatment for depression. His depressive conditions were subsequently improved due to ketamine therapy, however, he had recurrent hypoglycemia episodes. Clinicians should be aware of this potential adverse effect on initiating ketamine infusion with patients who had type 1 diabetes.
RESUMO
OBJECTIVE: The association between proton pump inhibitor (PPI) and dementia was controversial. The aim of the current study was to perform an updated pharmacovigilance analysis of the association between dementia event and PPI treatment after minimizing competition bias. METHODS: We gathered cases reported with PPI treatment based on the United States Food and Drug Administration Adverse Event Reporting System database from 2004 to 2023. We employed disproportionality algorithms, including reporting odds ratio (ROR) and the information component (IC), to detect the association between dementia event and PPI. We investigated the affection of event competition bias on the current disproportionality signal detection. RESULTS: We finally included a total of 776,191 PPI cases, and 1813 cases in the dementia group. Analyzing primary suspect PPIs, we detected a significant association between dementia and PPI (ROR = 1.38, 95%CI 1.22 to 1.56; IC = 0.46, 95%CI 0.04 to 0.86). After excluding the PPI case with renal injury events, the strength of the dementia signal increased. Omeprazole (589 cases), pantoprazole (514 cases), and esomeprazole (386 cases) were the top three PPI reported with dementia events. CONCLUSION: The current pharmacovigilance study identified a significant association between dementia and PPIs, except vonoprazan and tegoprazan, especially taking competition bias into account. Further high-quality prospective study still needed.
RESUMO
BACKGROUND: Pharmacovigilance entails monitoring of patients for timely detection of ADR and reporting them so that more information about drug safety can be obtained. This may help in the future for dose modification or alteration of regimen. In NTEP, ADSm (Active Drug Safety monitoring) is part of pharmacovigilance. In this study we shall be studying ADRs to Anti TB drugs in DRTB. METHODOLOGY: This study is observational, retrospective and record based, of patients admitted from 2021 to 2023 in the DOTS ward of Respiratory Medicine Department of a tertiary care hospital in Goa. Data such as age, sex, regimen, date of AKT initiation and adverse effects documented has been noted and compiled. RESULTS: ADRs have been tabulated in the form of tables. Statistical analysis is done to find out the commonest ADR, time when they are likely to occur, which age and gender are most likely affected and if there are any other associated risk factors for ADRs. CONCLUSION: This study will enable in future to better monitor patients with regard to particular adverse drug reaction, patient safety and if needed to alter the regimen as early as possible.

In Veneto Region, HPV vaccine has been actively offered to 12 year-old females since 2008, and to 12 year-old males since 2015. The study aims to analyze the safety profile of HPV4v and HPV9v vaccines and perform a case-by-case review of conditions of interest. Spontaneous reports related to HPV uploaded to the database of the Regional Pharmacovigilance Center between 2008-2022 were included. HPV vaccine doses administered until April 2022 in the Veneto Region were considered to calculate the reporting rate (RR). Potential "safety concerns" examined as conditions of interest were included through Standardized MedDRA or preferred terms searching queries. The level of diagnostic certainty was evaluated as per the Brighton Collaboration case definition criteria. A total of 637 reports and 1316 Adverse Events Following Immunizations (AEFI) were retrieved: 469 for HPV4v (73.6 %) and 168 for HPV9v (26.4 %). Serious reports were 71 (11.1 %): 49 (10.4 %) for HPV4v and 22 (13.1 %) for HPV9v. The RR for serious events between 2008-2022 was 6.9/100,000 administered doses, with no differences by vaccine type. Females and adults showed higher overall RR compared to males and to children and adolescents (p < 0.001), this result was confirmed by stratifying analysis by vaccine type. One case of Guillain Barré syndrome, anaphylactic shock, thrombocytopenia, Henoch Schoenlein purpura and four generalized seizures were reviewed. Vaccinovigilance data from the Veneto Region reaffirm a good safety profile for HPV vaccination and found no vaccine-related unexpected events. Such a detailed analysis may assist healthcare providers to advocate properly for HPV vaccination.
RESUMO
BACKGROUND: Adverse Drug Events (ADE) are key information present in unstructured portions of Electronic Health Records. These pose a significant challenge in healthcare, ranging from mild discomfort to severe complications, and can impact patient safety and treatment outcomes. METHODS: We explore the influence of domain shift between a set of dummy clinical notes and a real-world hospital corpus of Japanese clinical notes of breast cancer treatment when extracting ADEs from free text. We annotated a subset of the hospital dataset and used it to fine-tune a Named Entity Recognition (NER) model, initially trained with the set of dummy documents. We used increasing amounts of the annotated data and evaluated the impact on the model's performance. Additionally, we examined the extracted information to identify combinations of drugs that are likely to cause ADEs. RESULTS: We show that domain adaptation can significantly improve model performance in the new domain, as by feeding a small subset of 100 documents for the fine-tuning process we saw a 40% improvement in model performance. However, we also noticed diminishing returns when fine-tuning the model with a larger dataset. For instance, by feeding eight times more data, we only saw further 18% improvement in extraction performance. CONCLUSION: While variations in writing style and vocabulary in clinical corpora can significantly impact the quality of NER results. We show that domain adaptation can be of great aid in mitigating these discrepancies and achieving better performance. Yet, while providing in-domain data to a model helps, there are diminishing returns when fine-tuning with large amounts of data.
RESUMO
BACKGROUND: The COVID-19 pandemic, caused by SARS-CoV-2, has had a profound impact worldwide, leading to widespread morbidity and mortality. Vaccination against COVID-19 is a critical tool in controlling the spread of the virus and reducing the severity of the disease. However, the rapid development and deployment of COVID-19 vaccines have raised concerns about potential adverse events following immunization (AEFIs). Understanding the temporal and spatial patterns of these AEFIs is crucial for an effective public health response and vaccine safety monitoring. OBJECTIVE: This study aimed to analyze the temporal and spatial characteristics of AEFIs associated with COVID-19 vaccines in the United States reported to the Vaccine Adverse Event Reporting System (VAERS), thereby providing insights into the patterns and distributions of the AEFIs, the safety profile of COVID-19 vaccines, and potential risk factors associated with the AEFIs. METHODS: We conducted a retrospective analysis of administration data from the Centers for Disease Control and Prevention (n=663,822,575) and reports from the surveillance system VAERS (n=900,522) between 2020 and 2022. To gain a broader understanding of postvaccination AEFIs reported, we categorized them into system organ classes (SOCs) according to the Medical Dictionary for Regulatory Activities. Additionally, we performed temporal analysis to examine the trends of AEFIs in all VAERS reports, those related to Pfizer-BioNTech and Moderna, and the top 10 AEFI trends in serious reports. We also compared the similarity of symptoms across various regions within the United States. RESULTS: Our findings revealed that the most frequently reported symptoms following COVID-19 vaccination were headache (n=141,186, 15.68%), pyrexia (n=122,120, 13.56%), and fatigue (n=121,910, 13.54%). The most common symptom combination was chills and pyrexia (n=56,954, 6.32%). Initially, general disorders and administration site conditions (SOC 22) were the most prevalent class reported. Moderna exhibited a higher reporting rate of AEFIs compared to Pfizer-BioNTech. Over time, we observed a decreasing reporting rate of AEFIs associated with COVID-19 vaccines. In addition, the overall rates of AEFIs between the Pfizer-BioNTech and Moderna vaccines were comparable. In terms of spatial analysis, the middle and north regions of the United States displayed a higher reporting rate of AEFIs associated with COVID-19 vaccines, while the southeast and south-central regions showed notable similarity in symptoms reported. CONCLUSIONS: This study provides valuable insights into the temporal and spatial patterns of AEFIs associated with COVID-19 vaccines in the United States. The findings underscore the critical need for increasing vaccination coverage, as well as ongoing surveillance and monitoring of AEFIs. Implementing targeted monitoring programs can facilitate the effective and efficient management of AEFIs, enhancing public confidence in future COVID-19 vaccine campaigns.

Interstitial lung disease (ILD) is a serious adverse event caused by the administration of immune checkpoint inhibitors (ICIs). However, only few large-scale studies have explored the association among ICI use, underlying cancer type, and ILD complications. This study aimed to analyze the association between the primary cancer type and ICI-induced ILD in a cross-sectional manner using the Japanese Adverse Drug Event Report (JADER) database. Nivolumab and pembrolizumab (anti-programmed cell death 1 (PD-1) antibodies) and durvalumab, avelumab, and atezolizumab (anti-programmed cell death ligand 1 (PD-L1) antibodies) were included as ICIs in this study. Adverse events were identified based on the preferred terms of Medical Dictionary for Regulatory Activities (MedDRA) version 27.0/J listed in the Standardized MedDRA Queries (SMQ) "interstitial lung disease." The reporting odds ratio was calculated to detect the association between ICI use and ILD complications, and a signal was detected if the lower limit of the 95% confidence interval exceeded 1. In the analysis of all cancer types, a signal was detected for all ICIs except avelumab. An association between ICI and ILD was detected for all cancer types with nivolumab. However, pembrolizumab exhibited a signal only in colorectal cancer. In contrast, anti-PD-L1 antibodies displayed signals in five cancer types, excluding head and neck cancer, which was not reported in JADER. Among these cancer types, atezolizumab exhibited a signal only in breast cancer. The results of this study will help guide the safe use of ICIs based on the underlying cancer type in terms of ILD complications.

BACKGROUND/AIM: A few case reports of central nervous system (CNS) symptoms caused by amantadine intoxication have been published, detailing various types of symptoms and differing times to onset. We encountered a patient who developed CNS symptoms with amantadine. This prompted us to investigate the types, time to onset, and outcome of CNS adverse reactions to amantadine by analyzing data from a pharmacovigilance database. PATIENTS AND METHODS: The patient was evaluated at Chutoen General Hospital, Shizuoka, Japan. Analysis was performed using the Japanese Adverse Drug Event Report (JADER) database. RESULTS: In our case, the amantadine blood concentration was 4,042 ng/ml, i.e., in the toxic range. The time to onset was 26 days for dyskinesia and 90 days for depressed level of consciousness. Symptoms resolved when amantadine was discontinued. The JADER database contained 974 cases of adverse reactions to amantadine. The most frequently reported CNS adverse reaction was hallucination, with a reporting odds ratio of 64.28 (95% confidence interval=52.67-78.46). Positive signals were detected for all CNS adverse reactions. For all CNS reactions, clinical outcomes were poor in a comparatively low percentage of cases. Most CNS reactions occurred soon after administration of amantadine, usually within approximately one month. CONCLUSION: Because most CNS adverse reactions to amantadine usually occur within approximately one month of initiating treatment, healthcare providers should exercise heightened vigilance in monitoring patients for such reactions during this period.

BACKGROUND: Based on several case reports and observational studies, there is a growing concern regarding the potential association between roxadustat, a hypoxia-inducible factor prolyl-hydroxylase inhibitor, and suppression of thyroid function. In this systematic review and meta-analysis (PROSPERO: CRD42023471516), we aimed to evaluate the relationship between roxadustat use and suppression of thyroid function. METHODS: We conducted a comprehensive search of MEDLINE via PubMed, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials databases using the search term "roxadustat" to identify all relevant studies. The study population comprised adults with renal anemia who participated in a randomized controlled trial or observational study, with roxadustat as the intervention and a placebo or erythropoiesis-stimulating agent (ESA) as the comparator. The primary outcome was suppression of thyroid function and the secondary outcome was hypothyroidism. A meta-analysis was conducted using the DerSimonian-Laird random effects model based on the size of the intention-to-treat population, and the odds ratio (OR) and 95% confidence interval (CI) were calculated. Two reviewers independently screened the articles, extracted data, and assessed studies using the ROBINS-I tool. RESULTS: Of the six studies eligible for inclusion, a meta-analysis was performed using data from two observational studies comparing roxadustat and ESA. The meta-analysis showed that the incidence of suppression of thyroid function was significantly higher with roxadustat use than with ESA use (OR: 6.45; 95% CI: 3.39-12.27; I2 = 12%). Compared with ESA, roxadustat seemed to potentially increase the risk for suppression of thyroid function in patients with renal anemia. CONCLUSIONS: Our findings highlighted the importance of monitoring thyroid function in patients treated with roxadustat. The results of this review may enhance the safety of using roxadustat to treat renal anemia through advance recognition of the risk for suppression of thyroid function.
RESUMO
OBJECTIVES: To investigate the proportion, characteristics, causality, severity, preventability, and independently associated factors for adverse drug event (ADE)-related admissions in aged care residents admitted to the major public hospitals in Tasmania, Australia. DESIGN: Retrospective cross-sectional study. SETTING AND PARTICIPANTS: Residential aged care facility (RACF) patients aged ≥65 years who had an unplanned admission to one of the 4 Tasmanian public hospitals between July 1, 2018, and June 30, 2021. METHODS: We accessed the medical records of RACF patients. The ADEs were initially identified via chart review and a trigger tool. Hospitalizations attributable to ADEs were then determined by expert consensus. The causality, preventability, and severity of each ADE admission were assessed using standard criteria. RESULTS: Ninety-one residents (18.2%) of 500 randomly selected experienced potential ADE-related hospitalizations. ADEs were considered possible (n = 58, 64%) or definite/probable (n = 33, 36%). The most common ADEs were falls (n = 19, 21%), hypotension (n = 16, 18%), and confusion or delirium (n = 10, 11%). ADEs were frequently associated with renin-angiotensin system inhibitors (n = 43, 47.3%), opioids (n = 43, 47.3%), and diuretics (n = 40, 44%). Most ADEs were of moderate severity (n = 90, 99%) and considered not preventable (n = 60, 66%). Rheumatologic disease [odds ratio (OR) 1.89, 95% CI 1.09-3.30; P = .024] and previous adverse drug reaction (ADR) (OR 12.91, 95% CI 6.84-24.37; P < .001) were associated with ADE hospitalizations. CONCLUSIONS AND IMPLICATIONS: This study highlights that hospitalization for moderately severe ADEs is common among RACF residents. Opioids and antihypertensives were the common drug classes associated with harm. Rheumatologic disease (due to opioids) and previous ADR were identified as independently associated factors, which may warrant tailored interventions.

INTRODUCTION: Empagliflozin is a sodium-glucose co-transporter-2 inhibitor used to treat type 2 diabetes (T2D) to improve glycemic control, reduce risk of cardiovascular death in patients with T2D, and treat patients with symptomatic chronic heart failure (HF) and chronic kidney disease (CKD). The safety profile of empagliflozin is well documented, although adverse events (AEs) remain of interest to clinicians. This study provides an up-to-date safety evaluation of empagliflozin. METHODS: Data were pooled from four long-term trials which included: patients with T2D and established cardiovascular disease (EMPA-REG OUTCOME), patients with HF, with/without diabetes (EMPEROR-Reduced and EMPEROR-Preserved), and patients with CKD, with/without diabetes (EMPA-KIDNEY). Since three of the four trials evaluated empagliflozin 10 mg, the meta-analysis was restricted to this dose. RESULTS: Total trial medication exposure was 19,727 patient-years for patients who received empagliflozin (n = 10,472) and 19,447 patient-years for placebo (n = 10,461). The percentages of patients with serious AEs, fatal AEs, and AEs leading to discontinuation were similar for both groups. The incidences of serious urinary tract infection and serious pyelonephritis or urosepsis were similar for both groups but higher for women taking empagliflozin versus placebo. Serious genital infections were not increased with empagliflozin versus placebo. There was a slight increase in ketoacidosis and serious volume depletion in patients who received empagliflozin versus placebo. The occurrence of serious acute kidney injury was lower with empagliflozin versus placebo. Empagliflozin was not associated with an increased incidence of severe hypoglycemia, bone fractures, or lower limb amputations. Empagliflozin is therefore considered safe in people without diabetes, the elderly, patients with very low estimated glomerular filtration rate, low body mass index, and HF. Safety is unaltered by blood pressure, concomitant medication for hypertension, HF, and immunosuppression. CONCLUSION: This meta-analysis of long-term safety data extends current knowledge and confirms the safety and tolerability of empagliflozin.
Empagliflozin is used in adults with type 2 diabetes mellitus (T2D) to improve blood glucose control and in people with T2D and established cardiovascular disease to reduce the risk of death from cardiovascular disease. Also, it is used to treat people with chronic heart failure or chronic kidney disease. Although many clinical trials have shown the effectiveness and safety of empagliflozin, the evaluation of adverse events (AEs) remains of interest. This study further examined the safety of empagliflozin by analyzing four large, long-term clinical trials. These trials included over 20,900 patients with T2D and established cardiovascular disease, patients with heart failure, and patients with chronic kidney disease. Adverse events of interest were pooled and analyzed. Results show the risk of the investigated AEs was similar whether patients had received empagliflozin or placebo. The risk of urinary tract infections, including those that spread to the kidneys, was higher for women taking empagliflozin versus placebo. Ketoacidosis was rare but more frequent in patients taking empagliflozin. A reduction in blood volume was slightly more frequent in people taking empagliflozin versus placebo. The risk of kidney injury was reduced in patients taking empagliflozin versus placebo. The risk of genital infections, hypoglycemia, bone fractures, or lower limb amputations was not increased with empagliflozin. No new safety concerns were raised, including in people who were elderly, had kidney disease, low body weight, T2D, or heart failure. This analysis is consistent with current knowledge of empagliflozin safety in a broad range of patients.

Nonsteroidal anti-inflammatory drug (NSAID)-induced aseptic meningitis (NIAM) is frequently reported in patients with autoimmune disease. Ibuprofen-induced NIAM is the most common case report of NIAM. We report a patient without autoimmune disease who developed NIAM following oral celecoxib administration. A literature review and survey of cases registered in the Japanese Adverse Drug Event Report (JADER) database is also provided. A 73-year-old woman with no autoimmune disease developed a headache the day after taking celecoxib, and NIAM was suspected. The headache resolved quickly following celecoxib discontinuation. Although lumbar puncture was not available in this case, bacterial or viral meningitis was negative, and NIAM could not be ruled out. This case involved an older adult patient without an autoimmune disease, with celecoxib as the causative NSAID. A literature review found numerous cases of autoimmune diseases in younger patients. To date, only one case of celecoxib-induced NIAM has been reported. Analysis of NIAM cases in JADER revealed an onset time of approximately three days. JADER analysis indicated that NIAM tended to occur immediately after administration, although the onset with cyclooxygenase-2 selective agents might be slower.
RESUMO
Background: Anti-retroviral therapy-related adverse drug events are accounted as a main cause of anti-retroviral therapy non-adherence. In Sudan, pharmacovigilance studies are relatively rare and obstructed by the problem of under-reporting. It is a well-defined issue worldwide and is highly reported in developing countries. This study aimed to evaluate the prevalence of adverse events associated with anti-retroviral therapy among adult patients with immunodeficiency virus at Omdurman Voluntary Counselling and Testing and Anti-retroviral Therapy Center. Methods: The study was a descriptive cross-sectional study conducted through direct interviews with 429 patients at the selected center using the Adverse Drug Events (ADEs) reporting form. The collected data were analyzed by The Statistical Package for Social Sciences. Results: More than half (55.5%) of the participants experienced adverse events, with 48.7% having experienced them at the beginning of treatment. Central nervous system manifestations were the most common adverse events. By using the Naranjo scale, most adverse events showed a "probable" relationship to anti-retroviral medicines. Based on the chi-square test, medication regimen was significantly associated with the presence of ADEs (namely abdominal pain and jaundice) (p values = 0.03 and 0.001), respectively. Conclusion: This study clearly stated that ART-related ADEs are common among Sudanese PLHIV and with central nervous system being the main adverse events. More pharmacovigilance studies and efforts by healthcare providers should be applied targeting ART-related ADEs under-reporting in Sudanese healthcare facilities.
