Do classic psychedelics increase the risk of seizures? A scoping review
Eur Neuropsychopharmacol. 2024 Jun 24;85:35-42. doi: 10.1016/j.euroneuro.2024.05.002. Online ahead of print.
ABSTRACT
Seizures are a concerning adverse event frequently associated with the use of psychedelics, and hence, studies involving these substances tend to exclude patients with past history of epilepsy. This is especially relevant because epileptic seizures are markedly increased in the population suffering from mental disorders, and psychedelic assisted therapy is being researched as a promising treatment for several of them. To determine the extent of the current literature on the relationship between classic psychedelics and seizures, a scoping review was performed using the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews). The search was conducted in PubMed, Web of Science, Google scholar, LILACS and Scielo, and both animal and human models were included. A total of 16 publications on humans, and 11 on animals, were found. The results are heterogeneous, but globally suggest that psychedelics may not increase the risk of seizures in healthy individuals or animals in the absence of other drugs. However, concomitant use of other substances or drugs, such as kambo or lithium, could increase the risk of seizures. Additionally, these conclusions are drawn from data lacking sufficient external validity, so they should be interpreted with caution. Future paths for research and a summary on possible neurobiological underpinnings that might clarify the relationship between classical psychedelics and seizures are also provided.

Possible adverse events of imidazole antifungal drugs during treatment of vulvovaginal candidiasis: analysis of the FDA Adverse Event Reporting System
Sci Rep. 2024 Jun 24;14(1):14560. doi: 10.1038/s41598-024-63315-1.
ABSTRACT
Azole antifungal drugs are commonly used to treat vulvovaginal candidiasis (VVC). The nephrotoxicity and developmental toxicity of azole drugs have not been systematically analyzed in the real world. We used the FDA Adverse Event Reporting System (FAERS) to investigate the adverse events (AEs) associated with imidazole therapy for VVC. FAERS data (from quarter 1 2004 to quarter 3 2022) were retrieved using OpenVigil 2.1, and AEs were retrieved and standardized according to the Medical Dictionary for Regulatory Activities (MedDRA). In the top 10 System Organ Class (SOC), all four drugs have been found to have kidney and urinary system diseases and pregnancy. We found significant signals, including clotrimazole [bladder transitional cell carcinoma, (report odds ratio, ROR = 291.66)], [fetal death, (ROR = 10.28)], ketoconazole[nephrogenic anemia (ROR = 22.1)], [premature rupture of membranes (ROR = 22.91 46.45, 11, 3)], Miconazole[hematuria (ROR = 19.03)], [neonatal sepsis (ROR = 123.71)], [spontaneous abortion (ROR = 5.98)], Econazole [acute kidney injury (ROR = 4.41)], [spontaneous abortion (ROR = 19.62)]. We also discovered new adverse reactions that were not reported. Therefore, when using imidazole drugs for treatment, it is necessary to closely monitor the patient's renal function, pay attention to the developmental toxicity of the fetus during pregnancy, and be aware of potential adverse reactions that may occur.

Efficacy and side effects of pembrolizumab plus chemotherapy vs. chemotherapy alone in patients with advanced gastric or gastroesophageal junction adenocarcinoma: A meta-analysis
Oncol Lett. 2024 Jun 12;28(2):371. doi: 10.3892/ol.2024.14504. eCollection 2024 Aug.
ABSTRACT
Recently, the treatment plan of pembrolizumab plus chemotherapy was regarded as a promising treatment for patients with advanced gastric cancer or gastroesophageal junction adenocarcinoma (GC/GEJC). However, the efficacy and side effects of pembrolizumab plus chemotherapy still lack evidence-based medical evidence to support. Therefore, a meta-analysis was conducted to evaluate the hot issue. By searching PubMed, EMBASE, Cochrane Library, Web of Science, any randomized clinical studies of pembrolizumab plus chemotherapy versus chemotherapy in patients with advanced GC/GEJC met the inclusion criteria were included. The quality of the literature was evaluated and the data was extracted. A correlative software was also used to analyze the data and to draw a conclusion. After screening 14,015 studies, four studies were eligible for the meta-analysis. Compared with chemotherapy alone group, the overall survival (OS) rate was significantly longer. In programmed cell death ligand 1 (PD-L1) combined positive score (CPS) ≥1 subgroup and PD-L1 CPS ≥10 subgroup analyses, the results showed that the response rate (RR) and complete response rate (CR) were both higher in pembrolizumab plus chemotherapy group compared with chemotherapy alone group. There were not significant differences in the CR, the treatment-related adverse events, succumbed to drug-related events and succumbed to immune-mediated events between the two groups. However, the effect events such as the treatment-related adverse events led to discontinuation, the 3-5 treatment-related adverse events and the immune-mediated adverse events and infusion reactions were more common in pembrolizumab plus chemotherapy group. In conclusion, the current meta-analysis revealed that, in treating advanced GC/GEJC, pembrolizumab plus chemotherapy had improved therapeutic efficacies than chemotherapy alone, as evidenced by the significantly longer OS. Furthermore, the patients in PD-L1 CPS ≥1 subgroup and PD-L1 CPS ≥10 subgroup appeared to benefit from pembrolizumab plus chemotherapy treatment because of higher RR and CR. However, side effects such as the treatment-related adverse events leading to discontinuation, the 3-5 treatment-related adverse events, and immune-mediated adverse events and infusion reactions deserved more attention.

Adrenal Insufficiency and Thyrotoxicosis Following Combined Immune Checkpoint Inhibitor Use: A Case Report and Literature Review
Cureus. 2024 May 22;16(5):e60850. doi: 10.7759/cureus.60850. eCollection 2024 May.
ABSTRACT
Destructive thyroiditis and secondary adrenal insufficiency are major endocrinological immune-related adverse events of immune checkpoint inhibitors (ICIs). However, the timing at which each event occurs most frequently after drug administration varies, and cases where multiple events occur simultaneously are rare. We encountered a patient who concurrently suffered from thyrotoxicosis and adrenal insufficiency. An 80-year-old woman with a history of type 2 diabetes mellitus (DM) was diagnosed with stage IVA squamous cell carcinoma of the lungs. Treatment with a combination of nivolumab and ipilimumab was initiated. Although she tested positive for thyroglobulin antibody and transient subclinical hyperthyroidism was observed after two courses, treatment with ICIs was continued. Four months later, treatment was discontinued due to drug-induced lung disease. One month after the last administration, the patient became unconscious and was admitted to another hospital, diagnosed with diabetic ketoacidosis, urinary tract infection, and sepsis. After acute-phase treatment, she was transferred to our hospital due to persistent fever and tachycardia. Thyrotoxicosis and adrenal insufficiency were observed, with high levels of free thyroxine, low thyroid-stimulating hormone (TSH), and cortisol levels. Treatment with extracellular fluids, potassium iodide, beta-blockers, and hydrocortisone was initiated, and the patient's condition improved. No other pituitary hormone deficiencies were observed. She was diagnosed with painless thyroiditis and secondary adrenal insufficiency based on the positive thyroglobulin antibody, negative TSH receptor antibody, decreased Doppler flow in thyroid ultrasonography, low adrenocorticotrophic hormone (ACTH), and low response of ACTH and cortisol to corticotropin-releasing hormone loading test. MRI revealed no abnormalities. We report a case of thyrotoxicosis and secondary adrenal insufficiency five months after the first administration of nivolumab and ipilimumab. Careful follow-up and early detection of endocrine disorders are critical in patients treated with a combination of ICIs.

Treatment of Tislelizumab-Induced Toxic Epidermal Necrolysis and Agranulocytosis: A Case Report and Literature Review
Curr Drug Saf. 2024 Jun 20. doi: 10.2174/0115748863297885240604111018. Online ahead of print.
ABSTRACT
BACKGROUND: Non-small Cell Lung Cancer (NSCLC) makes up about 85% of lung cancer cases, mainly adenocarcinoma and squamous cell carcinoma. Recently, PD-1 inhibitors have become crucial in NSCLC treatment, significantly enhancing survival for some. However, side effects, like skin reactions and hematotoxicity, limit their use, with drug-induced TEN and immunotherapy-induced agranulocytosis as severe adverse effects.
CASE PRESENTATION: Herein, we have reported the case of a 75-year-old male diagnosed with metastatic Lung Squamous cell Carcinoma (LUSC) in the left lung. He received first-line treatment with one cycle of tislelizumab in combination with nab-paclitaxel and carboplatin, after which he developed Toxic Epidermal Necrolysis (TEN) and granulocytopenia. To address these two serious immune-related Adverse Events (irAEs), the patient was administered methylprednisolone in combination with gamma globulin for TEN and dexamethasone in combination with G-CSF for agranulocytosis. Antibiotics were also administered according to the patient's medication regimen. After treatment, the patient recovered and was discharged from the hospital. It was also noted that the lung tumor condition improved.
CONCLUSION: Effective management of severe immune-related side effects from tislelizumab, including TEN and agranulocytosis, can be partly achieved through steroids, gamma globulin, GCSF, and antibiotics. This strategy not only alleviates these adverse effects, but also potentially improves tumor conditions, highlighting the crucial role of vigilant monitoring and management in immunotherapy.

A proposal for using benefit-risk methods to improve the prominence of adverse event results when reporting trials
Trials. 2024 Jun 22;25(1):409. doi: 10.1186/s13063-024-08228-0.
ABSTRACT
Adverse events suffer from poor reporting within randomised controlled trials, despite them being crucial to the evaluation of a treatment. A recent update to the CONSORT harms checklist aims to improve reporting by providing structure and consistency to the information presented. We propose an extension wherein harms would be reported in conjunction with effectiveness outcome(s) rather than in silo to provide a more complete picture of the evidence acquired within a trial. Benefit-risk methods are designed to simultaneously consider both benefits and risks, and therefore, we believe these methods could be implemented to improve the prominence of adverse events when reporting trials. The aim of this article is to use case studies to demonstrate the practical utility of benefit-risk methods to present adverse events results alongside effectiveness results. Two randomised controlled trials have been selected as case studies, the Option-DM trial and the SANAD II trial. Using a previous review, a shortlist of 17 benefit-risk methods which could potentially be used for reporting RCTs was created. From this shortlist, three benefit-risk methods are applied across the two case studies. We selected these methods for their usefulness to achieve the aim of this paper and which are commonly used in the literature. The methods selected were the Benefit-Risk Action Team (BRAT) Framework, net clinical benefit (NCB), and the Outcome Measures in Rheumatology (OMERACT) 3 × 3 table. Results using the benefit-risk method added further context and detail to the clinical summaries made from the trials. In the case of the SANAD II trial, the clinicians concluded that despite the primary outcome being improved by the treatment, the increase in adverse events negated the improvement and the treatment was therefore not recommended. The benefit-risk methods applied to this case study outlined the data that this decision was based on in a clear and transparent way. Using benefit-risk methods to report the results of trials can increase the prominence of adverse event results by presenting them alongside the primary efficacy/effectiveness outcomes. This ensures that all the factors which would be used to determine whether a treatment would be recommended are transparent to the reader.

Reduction of prescription error and its adverse effects in the pediatric intensive care area
Medicina (B Aires). 2024;84(3):426-432.
ABSTRACT
INTRODUCTION: Prescription is the node of medication management and use that most frequently presents medication errors, according to various studies. This study aims to analyze prescriptions before and after the incorporation of a multidisciplinary round in the pediatric intensive care area and its implication in the occurrence of adverse drug events.
METHODS: This is an uncontrolled before and after study.
RESULTS: 100 patients were studied before and 100 after, range 1-17 years, mean age: 6.4 SD: 8.7. 55.5% (n = 111) were men. A prescription error was detected before the intervention of 12% (n = 12) and after 0% of the intervention, 0%, p = 0.001. A total of 45 adverse events were detected, that is, 45 adverse events per 100 admissions and 38, that is, 38 events per 100 admissions, before and after the intervention respectively (p > 0.05).
CONCLUSION: The intervention was useful to reduce prescription error in this sample of patients.

Efficacy and safety of albiglutide, a once-weekly glucagon-like peptide-1 receptor agonist, in patients with type 2 diabetes: A systematic review and meta-analysis
Medicine (Baltimore). 2024 Jun 21;103(25):e38568. doi: 10.1097/MD.0000000000038568.
ABSTRACT
BACKGROUND: No meta-analysis has holistically analyzed and summarized the therapeutic efficacy and safety of albiglutide in type 2 diabetes (T2D). This meta-analysis addresses this knowledge gap.
METHODS: Randomized controlled trials involving patients with T2D receiving albiglutide in the intervention arm and either a placebo or an active comparator in the control arm were searched through electronic databases. The primary outcome was the change from baseline (CFB) in glycated hemoglobin (HbA1c); secondary outcomes included CFB in fasting plasma glucose, body weight, and adverse events (AE).
RESULTS: From 443 initially screened articles, data from 12 randomized controlled trials involving 6423 subjects were analyzed. Albiglutide, at both doses, outperformed placebo in terms of HbA1c reductions (for albiglutide 30 mg: mean differences -1.04%, 95% confidence interval [CI] [-1.37--0.72], P < .00001, I2 = 89%; and for albiglutide 50 mg: mean differences -1.10%, 95% CI [-1.45--0.75], P < .00001, I2 = 90%). Higher proportions of subjects achieved HbA1c < 7% in the albiglutide arm than in placebo (for albiglutide 30 mg: odds ratio 6.26, 95% CI [2.50-15.70], P < .0001, I2 = 82%; and for albiglutide 50 mg: odds ratio 5.57, 95% CI [2.25-13.80], P = .0002, I2 = 84%). Albiglutide had glycemic efficacy comparable to other glucose-lowering drugs. CFB in body weight was similar with albiglutide and placebo. AE profile, including gastrointestinal AE, was identical with albiglutide and placebo, except for higher drug-related AE and injection-site reaction with albiglutide.
CONCLUSION: Albiglutide provides reassuring data on good glycemic efficacy, tolerability, and safety over an extended period of clinical use in patients with T2D. Albiglutide 30 mg has comparable efficacy and safety profiles to albiglutide 50 mg.

Effects of Oral ALZ-801/Valiltramiprosate on Plasma Biomarkers, Brain Hippocampal Volume, and Cognition: Results of 2-Year Single-Arm, Open-Label, Phase 2 Trial in APOE4 Carriers with Early Alzheimer's Disease
Drugs. 2024 Jun 20. doi: 10.1007/s40265-024-02067-8. Online ahead of print.
ABSTRACT
INTRODUCTION: ALZ-801/valiltramiprosate is a small-molecule oral inhibitor of beta amyloid (Aβ) aggregation and oligomer formation being studied in a phase 2 trial in APOE4 carriers with early Alzheimer's disease (AD) to evaluate treatment effects on fluid and imaging biomarkers and cognitive assessments.
METHODS: The single-arm, open-label phase 2 trial was designed to evaluate the effects of the ALZ-801 265 mg tablet taken twice daily (after 2 weeks once daily) on plasma fluid AD biomarkers, hippocampal volume (HV), and cognition over 104 weeks in APOE4 carriers. The study enrolled subjects aged 50-80 years, with early AD [Mini-Mental State Examination (MMSE) ≥ 22, Clinical Dementia Rating-Global (CDR-G) 0.5 or 1], apolipoprotein E4 (APOE4) genotypes including APOE4/4 and APOE3/4 genotypes, and positive cerebrospinal fluid (CSF) AD biomarkers or prior amyloid scans. The primary outcome was plasma p-tau181, HV evaluated by magnetic resonance imaging (MRI) was the key secondary outcome, and plasma Aβ42 and Aβ40 were the secondary biomarker outcomes. The cognitive outcomes were the Rey Auditory Verbal Learning Test and the Digit Symbol Substitution Test. Safety and tolerability evaluations included treatment-emergent adverse events and amyloid-related imaging abnormalities (ARIA). The study was designed and powered to detect 15% reduction from baseline in plasma p-tau181 at the 104-week endpoint. A sample size of 80 subjects provided adequate power to detect this difference at a significance level of 0.05 using a two-sided paired t-test.
RESULTS: The enrolled population of 84 subjects (31 homozygotes and 53 heterozygotes) was 52% females, mean age 69 years, MMSE 25.7 [70% mild cognitive impairment (MCI), 30% mild AD] with 55% on cholinesterase inhibitors. Plasma p-tau181 reduction from baseline was significant (31%, p = 0.045) at 104 weeks and all prior visits; HV atrophy was significantly reduced (p = 0.0014) compared with matched external controls from an observational Early AD study. Memory scores showed minimal decline from baseline over 104 weeks and correlated significantly with decreased HV atrophy (Spearman's 0.44, p = 0.002). Common adverse events were COVID infection and mild nausea, and no drug-related serious adverse events were reported. Of 14 early terminations, 6 were due to nonserious treatment-emergent adverse events and 1 death due to COVID. There was no vasogenic brain edema observed on MRI over 104 weeks.
CONCLUSIONS: The effect of ALZ-801 on reducing plasma p-tau181 over 2 years demonstrates target engagement and supports its anti-Aβ oligomer action that leads to a robust decrease in amyloid-induced brain neurodegeneration. The significant correlation between reduced HV atrophy and cognitive stability over 2 years suggests a disease-modifying effect of ALZ-801 treatment in patients with early AD. Together with the favorable safety profile with no events of vasogenic brain edema, these results support further evaluation of ALZ-801 in a broader population of APOE4 carriers, who represent two-thirds of patients with AD.

Outpatient parenteral antibiotic therapy (OPAT) through elastomeric continuous infusion pumps in a real-life observational study: Characteristics, safety, and efficacy analysis
Enferm Infecc Microbiol Clin (Engl Ed). 2024 Jun 19:S2529-993X(24)00148-5. doi: 10.1016/j.eimce.2024.04.007. Online ahead of print.
ABSTRACT
INTRODUCTION: This study aimed to present real-life data on the use, efficacy, and safety of administering antibiotic therapy through portable elastomeric pumps (pEP) in the outpatient setting.
METHODS: This retrospective observational cohort study was conducted from January 2020 to May 2023 in a large academic hospital in Rome, Italy. All patients receiving antibiotic therapy via pEP were included up to a follow-up period of 90 days after the end of antibiotic therapy. The primary outcome was the treatment response. Secondary endpoints were adverse events attributable to the drug administered, the vascular catheter, or the infection itself.
RESULTS: Of the 490 patients referred to our outpatient parenteral antibiotic therapy (OPAT) unit, 94 (19.2%) received antibiotic therapy via pEP and were included in the final analysis. The most frequently treated infections were those involving bone and prosthetics, including spondylodiscitis (n=27; 28.8%). Most infections were due to Pseudomonas aeruginosa (n=55; 48.3%). Cefepime (n=32; 34.0%), piperacillin/tazobactam (n=29; 30.9%), ceftolozane/tazobactam (n=7; 7.5%), and oxacillin (n=7; 7.5%) were the most frequently administered antibiotics. The infection cure rate reached 88.3% (n=83). 12 patients (12.8%) reported adverse events, of which half (6.4%) were drug-related and half (6.4%) were line-related.
CONCLUSIONS: OPAT through portable elastomeric infusion pumps proved to be safe and effective. It also contributed to the reduction of healthcare costs, fully respecting the principles of personalized medicine. This strategy has emerged as a promising tool for antibiotic stewardship and infection control.

A phase II, non-comparative randomised trial of two treatments involving liposomal amphotericin B and miltefosine for post-kala-azar dermal leishmaniasis in India and Bangladesh
PLoS Negl Trop Dis. 2024 Jun 20;18(6):e0012242. doi: 10.1371/journal.pntd.0012242. eCollection 2024 Jun.
ABSTRACT
BACKGROUND: In Southeast Asia, treatment is recommended for all patients with post-kala-azar dermal leishmaniasis (PKDL). Adherence to the first-line regimen, twelve weeks of miltefosine (MF), is low and ocular toxicity has been observed with this exposure period. We assessed the safety and efficacy of two shorter-course treatments: liposomal amphotericin B (LAmB) alone and combined with MF.
METHODOLOGY/PRINCIPAL FINDINGS: An open-label, phase II, randomized, parallel-arm, non-comparative trial was conducted in patients with parasitologically confirmed PKDL, 6 to ≤60 years. Patients were assigned to 20 mg/kg LAmB (total dose, in five injections over 15 days) alone or combined with allometric MF (3 weeks). The primary endpoint was definitive cure at 12 months, defined as complete resolution of papular and nodular lesions and >80% re-pigmentation of macular lesions. Definitive cure at 24 months was a secondary efficacy endpoint. 118/126 patients completed the trial. Definitive cure at 12 months was observed in 29% (18/63) patients receiving LAmB and 30% (19/63) receiving LAmB/MF (mITT), increasing to 58% and 66%, respectively, at 24 months. Most lesions had resolved/improved at 12 and 24 months for patients receiving LAmB (90%, 83%) and LAmB/MF (85%, 88%) by qualitative assessment. One death, unrelated to study drugs, was reported; no study drug-related serious adverse events were observed. The most frequent adverse drug reactions were MF-related vomiting and nausea, and LAmB-related hypokalaemia and infusion reactions. Most adverse events were mild; no ocular adverse events occurred.
CONCLUSIONS/SIGNIFICANCE: Both regimens are suitably safe and efficacious alternatives to long-course MF for PKDL in South Asia.

Treatment patterns and survival outcomes of patients admitted to the intensive care unit due to immune-related adverse events of immune checkpoint inhibitors
Cancer Med. 2024 Jun;13(12):e7302. doi: 10.1002/cam4.7302.
ABSTRACT
INTRODUCTION: Severe immune-related adverse events (irAEs) due to immune checkpoint inhibitors (ICIs) can lead to admission to the intensive care unit (ICU). In this retrospective study, we determined the incidence, treatment patterns and survival outcomes of this patient population at a comprehensive cancer center.
METHODS: All patients admitted to the ICU due to irAEs from ICI treatment between January 2015 and July 2022 were included. Descriptive statistics were reported on patient characteristics and treatment patterns during hospital admission. Overall survival (OS) from the time of ICU discharge to death was estimated using the Kaplan-Meier method.
RESULTS: Over the study period, 5561 patients received at least one ICI administration, of which 32 patients (0.6%) were admitted to the ICU due to irAEs. Twenty patients were treated with anti-PD-1 plus anti-CTLA-4 treatment, whereas 12 patients were treated with ICI monotherapy. The type of irAEs were de novo diabetes-related ketoacidosis (n = 8), immune-related gastrointestinal toxicity (n = 8), myocarditis or myositis (n = 10), nephritis (n = 3), pneumonitis (n = 2), and myelitis (n = 1). The median duration of ICU admission was 3 days (interquartile range: 2-6 days). Three patients died during ICU admission. The median OS of the patients who were discharged from the ICU was 18 months (95% confidence interval, 5.0-NA).
CONCLUSION: The incidence of irAEs leading to ICU admission in patients treated with ICI was low in this study. ICU mortality due to irAEs was low and a subset of this patient population even had long-term survival.

A Case Report of Black Hairy Tongue (Melanotrichia Linguae or Lingua Pilosa Nigra)
Cureus. 2024 May 20;16(5):e60685. doi: 10.7759/cureus.60685. eCollection 2024 May.
ABSTRACT
Black hairy tongue is a benign condition that can be associated with several varying causes. Its etiology is often linked with fungal infection and adverse reactions to various drugs. We present a case of an adult patient who developed a black hairy tongue while on ceftriaxone and pantoprazole for 10 days. The fungus on his tongue was not identified as the causative agent, and recovery was achieved by changing his medications. Ceftriaxone was replaced with trimethoprim/sulfamethoxazole 5 mg/kg intravenous, and pantoprazole was fully stopped. The black lesion on the tongue was observed to regress over several days. Clinicians should be aware of this particular side effect of certain antibiotics.

Benzbromarone as adjuvant therapy for cystic fibrosis lung disease: a pilot clinical trial
J Bras Pneumol. 2024 Jun 17;50(3):e20230292. doi: 10.36416/1806-3756/e20230292. eCollection 2024.
ABSTRACT
OBJECTIVE: Cystic fibrosis (CF) affects multiple organs, the most severe consequences being observed in the lungs. Despite significant progress in developing CF transmembrane conductance regulator-specific treatments for CF lung disease, exploring alternative CF-targeted medications seems reasonable. We sought to evaluate the potential beneficial effects of oral benzbromarone as an adjuvant therapy in CF patients with reduced lung function.
METHODS: This was a prospective open-label pilot study of oral benzbromarone (100 mg/day) administered once daily for 90 days. Patients were followed at a tertiary referral center in southern Brazil. Safety was assessed by the number of reported adverse events. Secondary objectives included percent predicted FEV1 (FEV1%) and pulmonary exacerbations.
RESULTS: Ten patients were enrolled. Benzbromarone was found to be safe, with no serious drug-related adverse events. Eight patients completed the study; the median relative change in FEV1% tended to increase during the treatment, showing an 8% increase from baseline at the final visit. However, a nonparametric test showed that the change was not significant (p = 0.06). Of a total of ten patients, only one experienced at least one pulmonary exacerbation during the study.
CONCLUSIONS: Oral benzbromarone appears to be safe, and improved FEV1% has been observed in patients with CF. Further assessment in larger trials is warranted to elucidate whether oral benzbromarone can be a potential adjuvant therapy for CF.

Monitoring Adverse Drug Events in Web Forums: Evaluation of a Pipeline and Use Case Study
J Med Internet Res. 2024 Jun 18;26:e46176. doi: 10.2196/46176.
ABSTRACT
BACKGROUND: To mitigate safety concerns, regulatory agencies must make informed decisions regarding drug usage and adverse drug events (ADEs). The primary pharmacovigilance data stem from spontaneous reports by health care professionals. However, underreporting poses a notable challenge within the current system. Explorations into alternative sources, including electronic patient records and social media, have been undertaken. Nevertheless, social media's potential remains largely untapped in real-world scenarios.
OBJECTIVE: The challenge faced by regulatory agencies in using social media is primarily attributed to the absence of suitable tools to support decision makers. An effective tool should enable access to information via a graphical user interface, presenting data in a user-friendly manner rather than in their raw form. This interface should offer various visualization options, empowering users to choose representations that best convey the data and facilitate informed decision-making. Thus, this study aims to assess the potential of integrating social media into pharmacovigilance and enhancing decision-making with this novel data source. To achieve this, our objective was to develop and assess a pipeline that processes data from the extraction of web forum posts to the generation of indicators and alerts within a visual and interactive environment. The goal was to create a user-friendly tool that enables regulatory authorities to make better-informed decisions effectively.
METHODS: To enhance pharmacovigilance efforts, we have devised a pipeline comprising 4 distinct modules, each independently editable, aimed at efficiently analyzing health-related French web forums. These modules were (1) web forums' posts extraction, (2) web forums' posts annotation, (3) statistics and signal detection algorithm, and (4) a graphical user interface (GUI). We showcase the efficacy of the GUI through an illustrative case study involving the introduction of the new formula of Levothyrox in France. This event led to a surge in reports to the French regulatory authority.
RESULTS: Between January 1, 2017, and February 28, 2021, a total of 2,081,296 posts were extracted from 23 French web forums. These posts contained 437,192 normalized drug-ADE couples, annotated with the Anatomical Therapeutic Chemical (ATC) Classification and Medical Dictionary for Regulatory Activities (MedDRA). The analysis of the Levothyrox new formula revealed a notable pattern. In August 2017, there was a sharp increase in posts related to this medication on social media platforms, which coincided with a substantial uptick in reports submitted by patients to the national regulatory authority during the same period.
CONCLUSIONS: We demonstrated that conducting quantitative analysis using the GUI is straightforward and requires no coding. The results aligned with prior research and also offered potential insights into drug-related matters. Our hypothesis received partial confirmation because the final users were not involved in the evaluation process. Further studies, concentrating on ergonomics and the impact on professionals within regulatory agencies, are imperative for future research endeavors. We emphasized the versatility of our approach and the seamless interoperability between different modules over the performance of individual modules. Specifically, the annotation module was integrated early in the development process and could undergo substantial enhancement by leveraging contemporary techniques rooted in the Transformers architecture. Our pipeline holds potential applications in health surveillance by regulatory agencies or pharmaceutical companies, aiding in the identification of safety concerns. Moreover, it could be used by research teams for retrospective analysis of events.

Public interest in drug-related problems reflected in information search trends: an infodemiological study
Daru. 2024 Jun 18. doi: 10.1007/s40199-024-00519-w. Online ahead of print.
ABSTRACT
BACKGROUND: The analysis of how people search and "navigate" the internet to obtain health-related information and how they communicate and share this information can provide valuable knowledge about the disease patterns behaviour and health habits of populations.
OBJECTIVE: To determine the population's interest in drug-related problems through information search trends.
METHOD: A descriptive ecological correlational study, based on obtaining Google Trends data.
VARIABLES STUDIED: relative search volume (RSV), evolution over time, milestones and seasonality.
RESULTS: The most searched topic was drug overdose, with mean RSV of 56.25 ± 0.65. The highest increase occurred in the contraindication topic (R2 = 0.87, p < 0.001). The main milestone was observed in the drug overdose topic in July 2018 (RSV = 100). A very close relationship was found between adverse drug reaction and contraindication (R = 0.89, p < 0.001). Slight seasonality was noted in the adverse drug reaction (augmented Dickey-Fuller test [ADF] = -1.96), contraindication (ADF = -2.66) and drug interaction (ADF = -1.67) topics, but did not show an epidemiological trend.
CONCLUSIONS: The greatest public interest was found in the drug overdose and contraindication topics, which showed a stronger upward trend, although the seasonality study did not show any very notable data or demonstrate epidemiological information search behaviour. The main milestone observed was due to media factors related to the consumption of narcotics. There was a clear difference in English-speaking countries in the use of the drug overdose topic. A correlation between the adverse drug reaction and contraindication topics was confirmed.

Risk minimalisation measures for medications; are they incorporated in Dutch clinical guidelines?
Ned Tijdschr Geneeskd. 2024 Jun 25;168:D8139.
ABSTRACT
OBJECTIVE: Risk minimisation measures (RMM) are put in place to ensure safe and effective use of medicines. This study assessed whether RMM for five medicines are implemented in Dutch clinical guidelines.
DESIGN: Descriptive study.
METHOD: Dutch clinical guidelines where treatment with valproate, fluoroquinolones, methotrexate, metformin or fluorouracil was recommended were identified. In those guidelines that had been updated after publication of the RMM, we determined whether RMM-information was included in the guideline.
RESULTS: Out of 50 identified guidelines recommending treatment with one of the five medicines, only 21 (42%) were revised after RMM-implementation. Of these 21 guidelines, 12 (n = 57%) included RMM-related information.
CONCLUSION: Uptake of RMM information in Dutch clinical guidelines is limited and RMM-publication does not prompt guideline updates. This suggests that guidelines alone are not an optimal way to inform health care professionals of new safety warnings.

Risk management with regard to QT-prolonging drugs
Ned Tijdschr Geneeskd. 2024 Jun 19;168:D7453.
ABSTRACT
Drug-induced QT prolongation increases the risk of Torsade de Pointes (TdP). Drug-induced QT prolongation is a complex and unpredictable system due to many uncertainties. Risk factors such as electrolyte disturbances, heart failure and genetics play an important role in estimating the effect on QT prolongation. Moreover, the degree of QT prolongation is not always directly related to the risk of TdP and the assessment of the QT-interval is variable depending on the type and timing of QT measurement. Therefore, the variation in QT measurement may be larger than the effect of certain drugs on the QT interval. Because of the potentially lethal risk, several measures are undertaken to reduce the risk of QT prolongation and TdP, while their effect and proportionality are unclear. We suggest we should be less stringent in certain settings when risk of TdP is extremely low given the limited availability of our resources.
