ABSTRACT

Drug-induced myopathies are a common cause of muscle pain, and the range of drugs that can cause muscle side effects is constantly expanding. In this article, the authors comprehensively discuss the diagnostic and therapeutic process in patients with myalgia, and present the spectrum of drug-induced myopathies. The review provides a detailed analysis of the literature on the incidence of myopathy during treatment with hypolipemic drugs, beta-blockers, amiodarone, colchicine, glucocorticosteroids, antimalarials, cyclosporine, zidovudine, and checkpoint inhibitors, a group of drugs increasingly used in the treatment of malignancies. The article considers the clinical course of the different types of myopathies, their pathogenesis, histopathological features, and treatment methods of these disorders. The aim of this paper is to gather from the latest available literature up-to-date information on the course, pathophysiology, and therapeutic options of drug-induced myopathies, to systematize the knowledge of drug-induced myopathies and to draw the attention of internists to the fact that these clinical issues are an important therapeutic problem.

Genetic Variants in the <em>ABCB1</em> and <em>ABCG2</em> Gene Drug Transporters Involved in Gefitinib-Associated Adverse Reaction: A Systematic Review and Meta-Analysis

Sat, 2024-05-25 06:00

Genes (Basel). 2024 May 7;15(5):591. doi: 10.3390/genes15050591.

ABSTRACT

This systematic review and meta-analysis aimed to verify the association between the genetic variants of adenosine triphosphate (ATP)-binding cassette subfamily B member 1 (ABCB1) and ATP-binding cassette subfamily G member 2 (ABCG2) genes and the presence and severity of gefitinib-associated adverse reactions. We systematically searched PubMed, Virtual Health Library/Bireme, Scopus, Embase, and Web of Science databases for relevant studies published up to February 2024. In total, five studies were included in the review. Additionally, eight genetic variants related to ABCB1 (rs1045642, rs1128503, rs2032582, and rs1025836) and ABCG2 (rs2231142, rs2231137, rs2622604, and 15622C>T) genes were analyzed. Meta-analysis showed a significant association between the ABCB1 gene rs1045642 TT genotype and presence of diarrhea (OR = 5.41, 95% CI: 1.38-21.14, I2 = 0%), the ABCB1 gene rs1128503 TT genotype and CT + TT group and the presence of skin rash (OR = 4.37, 95% CI: 1.51-12.61, I2 = 0% and OR = 6.99, 95%CI: 1.61-30.30, I2= 0%, respectively), and the ABCG2 gene rs2231142 CC genotype and presence of diarrhea (OR = 3.87, 95% CI: 1.53-9.84, I2 = 39%). No ABCB1 or ABCG2 genes were positively associated with the severity of adverse reactions associated with gefitinib. In conclusion, this study showed that ABCB1 and ABCG2 variants are likely to exhibit clinical implications in predicting the presence of adverse reactions to gefitinib.

Evaluation of the knowledge of and attitudes towards pharmacovigilance among healthcare students in China: a cross-sectional study

Fri, 2024-05-24 06:00

BMC Med Educ. 2024 May 24;24(1):570. doi: 10.1186/s12909-024-05561-5.

ABSTRACT

BACKGROUND: Knowledge of pharmacovigilance (PV) and adverse drug reactions (ADRs) are the core competencies that healthcare students should acquire during their studies. The objective of this study was to assess attitudes towards and knowledge of PV and ADRs among healthcare students in China.

METHODS: An online, cross-sectional survey was conducted nationally among healthcare students in China from April through October 2023. Knowledge of PV and ADRs was assessed using a questionnaire based on current PV guidelines. We performed logistic regression analysis to determine the potential factors related to knowledge of and attitudes towards PV and ADRs.

RESULTS: A total of 345 students were included in the analysis. Among the healthcare students who participated in the survey, 225 (65.22%) students correctly defined PV, while only 68 (19.71%) had a correct understanding of ADRs. Among all respondents included in the analysis, only 71 (20.58%) reported having taken a PV course. Pharmacy students were more likely to have taken PV courses at a university and to demonstrate superior knowledge compared to other healthcare students. The logistic regression model revealed that the significant predictors of a higher level of PV knowledge were being female (odds ratio [OR]: 1.76; 95% confidence interval (CI): 1.06-2.92; P value: 0.028) and having previously taken PV-related courses (OR: 2.00; 95% CI: 1.06-3.80; P value: 0.034).

CONCLUSIONS: This study revealed that healthcare students' knowledge of PV and ADRs is unsatisfactory. However, there were a limited number of universities providing PV education. Given the vital role of healthcare professionals in identifying and reporting ADRs, our findings raise significant concerns. Hence, more efforts should be made to enhance PV education for future healthcare professionals.

Time-course of drug-related psychiatric and behavioral treatment-emergent adverse events during brivaracetam treatment in adults with focal-onset seizures

Fri, 2024-05-24 06:00

Epilepsy Behav. 2024 May 23;156:109844. doi: 10.1016/j.yebeh.2024.109844. Online ahead of print.

ABSTRACT

OBJECTIVE: We previously analyzed data from three phase lll trials of adjunctive brivaracetam (BRV) in adults showing that the incidence and prevalence of drug-related central nervous system treatment-emergent adverse events (TEAEs) quickly peaked and decreased over several weeks following BRV treatment initiation. However, that analysis did not assess psychiatric and behavioral side effects which can occur with antiseizure medication (ASM) treatment. Here, we investigate the time-course of psychiatric and behavioral TEAEs by week of BRV treatment and how these TEAEs were managed.

METHODS: Data were pooled from three trials (N01252 [NCT00490035]; N01253 [NCT00464269]; N01358 [NCT01261325]) in adult patients (≥16 years of age) with focal-onset seizures receiving BRV adjunctive therapy. This post hoc analysis reports data on the incidence and prevalence of drug-related psychiatric or behavioral TEAEs over time in patients who received BRV doses of 50-200 mg/day (without titration) or placebo (PBO) during the 12-week treatment period. A logistic regression model was used to determine if psychiatric or behavioral comorbid conditions were predictors for drug-related psychiatric or behavioral TEAEs, or BRV discontinuation due to psychiatric or behavioral TEAEs.

RESULTS: A total of 803 patients received BRV 50-200 mg/day, and 459 patients received PBO. Drug-related psychiatric or behavioral TEAEs were reported by 11.0 % of patients during adjunctive BRV treatment (PBO: 4.8 %) with onset early after BRV initiation (median time to onset of first drug-related psychiatric or behavioral TEAE: 15 days). Incidence peaked at week 1 and decreased over the first 4 weeks following BRV initiation. Prevalence peaked at week 4 and then remained stable between weeks 5-12. In an analysis excluding patients on concomitant levetiracetam (BRV: n = 744; PBO: n = 422), the incidence of drug-related psychiatric or behavioral TEAEs was similar to the incidence in the overall population. The most common drug-related psychiatric or behavioral TEAEs were irritability, insomnia, depression, and anxiety. Only 2 % of patients discontinued BRV due to psychiatric or behavioral TEAEs (PBO: 1.3 %), while most patients on BRV who reported drug-related psychiatric or behavioral TEAEs did not require a change in dose (84.1 %; PBO: 63.6 %). A history of psychiatric or behavioral comorbid conditions (not ongoing at BRV initiation) was not associated with an increased likelihood of drug-related psychiatric or behavioral TEAEs, or BRV discontinuation due to psychiatric or behavioral TEAEs. Ongoing psychiatric or behavioral comorbid conditions at BRV initiation increased the likelihood of drug-related psychiatric or behavioral TEAEs, but not the likelihood of BRV discontinuation due to psychiatric or behavioral TEAEs.

CONCLUSIONS: Drug-related psychiatric and behavioral TEAEs occurred early during BRV treatment, and most patients did not require a change in BRV dose. These data can help guide clinician monitoring and patient expectations after starting BRV.

Evaluation of 1,9-Dimethyl-Methylene Blue nanoencapsulation using rhamnolipid nanoparticles to potentiate the Photodynamic Therapy technique in Candida albicans: In vitro study

Fri, 2024-05-24 06:00

J Photochem Photobiol B. 2024 May 20;256:112943. doi: 10.1016/j.jphotobiol.2024.112943. Online ahead of print.

ABSTRACT

With the rapid development of nanotechnology, various functional nanomaterials have shown exciting potential in biomedical areas such as drug delivery, antitumor, and antibacterial therapy. These nanomaterials improve the stability and selectivity of loaded drugs, reduce drug-induced side effects, realize controlled and targeted drug release, and increase therapeutic efficacy. The increased resistance to antifungal microbicides in medical practice and their side effects stimulate interest in new therapies, such as Photodynamic Therapy (PDT), which do not generate resistance in microorganisms and effectively control the pathology. The present study aimed to evaluate, in vitro, the efficacy of photodynamic therapy on Candida albicans using 1,9-Dimethyl-Methylene Blue (DMMB) as photosensitizer, red LED (λ630), and nanoencapsulation of DMMB (RL-NPs/DMMB) using rhamnolipids produced by Pseudomonas aeruginosa to evaluate if there is better performance of DMMB + RL particles compared to DMMB alone via the characterization of DMMB + RL and colony forming count. The tests were carried out across six experimental groups (Control, DMMB, RL-NPs, RL-NPs/DMMB, PDT and PDT + RL-NPs/DMMB) using in the groups with nanoparticles, DMMB (750 ng/mL) encapsulated with rhamnolipids in a 1:1 ratio, the light source consisted of a prototype built with a set of red LEDs with an energy density of 20 J/cm2. The results showed that applying PDT combined with encapsulation (RL-NPs/DMMB) was a more practical approach to inhibit Candida albicans (2 log reduction) than conventional applications, with a possible clinical application protocol.

Fri, 2024-05-24 06:00

Cureus. 2024 May 23;16(5):e60898. doi: 10.7759/cureus.60898. eCollection 2024 May.

ABSTRACT

Background The hepatoprotective function of polyherbal formulation Liv.52 in chronic liver diseases is well recognized in published literature. The objective of this open-label, phase IV study was to further strengthen and validate its safety and effectiveness using a large patient pool in a real-world scenario and provide scientific data on symptomatic improvement and supportive treatment in liver function with improvement in quality of life. Methods Adult patients of either sex with one or more clinical symptoms like fatigue, nausea, anorexia, abdominal pain or discomfort, muscle cramps, jaundice, or any other signs and symptoms with a history suggestive of mild-to-moderate hepatic disorders like alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), drug-induced hepatotoxicity, or hepatitis were treated with two Liv.52 DS tablets (oral) twice daily for 12 weeks. Results Out of the 1000 enrolled patients, 962 (96%) completed the study with the following subgroups ALD: 375 (38.9%), NAFLD: 379 (39.3%), drug-induced hepatotoxicity: 78 (8.1%), hepatitis: 130 (13.5%). The mean age of enrolled patients was 37.7 years, and the majority of them, 785 (78.5%) were men. The common adverse events observed (with >1.5% incidence) in the study were abdominal pain: 26 (2.6%) and headache: 17 (1.7%). Liv.52 showed statistically significant improvement (P<0.0001) in various clinical signs and symptoms in the majority of patients namely, fatigue: 357/723 (49%), anorexia: 485/620 (78.2%), jaundice: 48/52 (92%). Majority of the patients showed significant improvements from baseline to end of 12 weeks in the liver function test parameters namely, aspartate aminotransferase: 633/840 (75.36%), alanine aminotransferase: 592/729 (81.21%), serum bilirubin: 244/347 (70.32%), alkaline phosphatase: 279/355 (78.59%) with P<0.0001 for all parameters. Statistically significant improvement (P<0.005) was also seen in all the components of the chronic liver disease questionnaire (CLDQ) scores from baseline to 12 weeks. Conclusions The study demonstrated that Liv.52 was hepatoprotective and well tolerated in the study population after treatment for 12 weeks. Significant improvements were seen in clinical signs and symptoms, laboratory parameters of liver function, and CLDQ scores from baseline to 12 weeks. No significant or new safety signals emerged from this study.

Assessing the safety of bedaquiline: insight from adverse event reporting system analysis

Fri, 2024-05-24 06:00

Front Pharmacol. 2024 May 9;15:1382441. doi: 10.3389/fphar.2024.1382441. eCollection 2024.

ABSTRACT

BACKGROUND: The development and marketing of Bedaquiline (BDQ) represent significant advancements in treating tuberculosis, particularly multidrug-resistant forms. However, comprehensive research into BDQ's real-world safety remains limited.

PURPOSE: We obtained BDQ related adverse event (AE) information from the US Food and Drug Administration's Adverse Event Reporting System (FAERS) to assess its safety and inform drug usage.

METHODS: The AE data for BDQ from 2012 Q4 to 2023 Q3 was collected and standardized. Disproportionality analysis, including Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Multi-item Gamma Poisson Shrinker (MGPS), and Bayesian Confidence Propagation Neural Network (BCPNN) was used to quantify signals of BDQ-related AEs. Logistic regression was used to analyze the individual data of hepatotoxicity and drug-induced liver injury, and multiple linear regression models were established. Additionally, network pharmacology was employed to identify the potential biological mechanisms of BDQ-induced liver injury.

RESULTS: We identified 2017 case reports directly related to BDQ. Our analysis identified 341 Preferred Terms (PTs) characterizing these AEs across 27 System Organ Classes (SOC). An important discovery was the identification of AEs associated with ear and labyrinth disorders, which had not been documented in the drug's official leaflet before. Subgroup analysis revealed a negative correlation between BDQ-related liver injury and females (OR: 0.4, 95%CI: 0.3-0.6). In addition, via network pharmacology approach, a total of 76 potential targets for BDQ related liver injury were predicted, and 11 core target genes were selected based on the characterization of protein-protein interactions. The pathway linked to BDQ-induced liver injury was identified, and it was determined that the PI3K-Akt signaling pathway contained the highest number of associated genes.

CONCLUSION: The analysis of the FAERS database revealed adverse events linked to BDQ, prompting the use of a network pharmacology approach to study the potential molecular mechanism of BDQ-induced liver injury. These findings emphasized the significance of drug safety and offered understanding into the mechanisms behind BDQ-induced liver injury. BDQ demonstrated distinct advantages, including reduced incidence of certain adverse events compared to traditional treatments such as injectable agents and second-line drugs. However, it is important to acknowledge the limitations of this analysis, including potential underreporting and confounding factors. This study provides valuable insights into the safety of BDQ and its role in the management of MDR-TB, emphasizing the need for continued surveillance and monitoring to ensure its safe and effective use.

Immunogenicity and safety of Ad26.RSV.preF/RSV preF protein vaccine at predicted intermediate- and end-of-shelf-life as an evaluation of potency throughout shelf life

Fri, 2024-05-24 06:00

Hum Vaccin Immunother. 2024 Dec 31;20(1):2344970. doi: 10.1080/21645515.2024.2344970. Epub 2024 May 23.

ABSTRACT

This study assessed three Ad26.RSV.preF/RSV preF protein combinations, combining different Ad26.RSV.preF doses and naturally aged preF protein, representing the expected critical vaccine quality attributes close to release, around intermediate shelf-life (ISL) and near-presumed end-of-shelf-life (EoSL), as a way to evaluate the vaccine immunogenicity and safety throughout its shelf-life. A single dose of Ad26.RSV.preF/RSV preF protein vaccine was administered to adults 60-75 years of age. Solicited adverse events (AEs), unsolicited AEs, and serious AEs (SAEs) were assessed for 7-day, 28-day, and 6-month periods after vaccination, respectively. RSV preF-binding antibody concentrations and RSV neutralizing titers were measured 14 days post-vaccination as primary and secondary endpoints, respectively; binding antibodies were also measured 6 months post-vaccination. The RSV preF-binding antibody responses induced by Ad26.RSV.preF/RSV preF protein vaccine lots representing the critical quality attributes around ISL and near presumed EoSL were noninferior to the responses induced by the vaccine lot representing the critical quality attributes near release. The RSV preF-binding and RSV neutralizing antibody levels measured 14 days post-vaccination were similar across the 3 groups. RSV preF-binding antibody concentrations were also similar 6 months post-vaccination. Solicited AEs were mostly mild to moderate in intensity, and a decreased reactogenicity was observed from the Release group to the ISL and EoSL group. None of the reported SAEs were considered related to study vaccination. The study provided evidence of sustained immunogenicity and safety over the intended shelf-life of the Ad26.RSV.pref/RSV preF protein vaccine. The three vaccine lots had acceptable safety profiles.

Medication-related incidents in acute care hospitals among different age groups: An analysis of national patient safety report data

Fri, 2024-05-24 06:00

Pharmacoepidemiol Drug Saf. 2024 Jun;33(6):e5819. doi: 10.1002/pds.5819.

ABSTRACT

PURPOSE: This study aimed to perform a nationwide analysis of medication errors (MEs) from hospitals using national reporting system data and to compare the ME patterns among different age groups.

METHODS: We analyzed medication-related incidents in acute care hospitals reported to the Korean Patient Safety Reporting and Learning System (KOPS), which is a patient safety reporting system, from July 2016 to December 2020. The stages of the medication use process, type of errors, medication class involved in MEs, and degree of harm were analyzed.

RESULTS: Among a total of 5071 medication-related incidents, 37.7% (1911 cases) were incidents that caused patient harm and 1.2% caused long-term, permanent, and fatal harm. The proportion of medication-related incidents that resulted in harm was the highest among the <1-year-old age group (67 cases, 51.5%), followed by the elderly (≥ 65 years) (828 cases, 40.9%). The cases leading to patient death were most frequently reported in patients aged ≥65 years. Medication-related incidents occurred mainly in the administration stage (2954 cases, 58.3%), and wrong dose was the most frequently reported ME type. The most prevalent medication class occurring in the 20-64-year age group (256 cases, 11.7%) was 'antibacterials for systemic use', whereas 'contrast media' (236 cases, 11.6%) and 'blood substitutes and perfusion solutions' (98 cases, 19.3%) were the most prevalent drug classes in the ≥65- and <20-year-old age groups, respectively.

CONCLUSIONS: It is necessary to establish guidelines for the prevention of medication-related incidents according to the medication use process and patient age group.

ABSTRACT

PURPOSE: Our objective is to describe how the U.S. Food and Drug Administration (FDA)'s Sentinel System implements best practices to ensure trust in drug safety studies using real-world data from disparate sources.

METHODS: We present a stepwise schematic for Sentinel's data harmonization, data quality check, query design and implementation, and reporting practices, and describe approaches to enhancing the transparency, reproducibility, and replicability of studies at each step.

CONCLUSIONS: Each Sentinel data partner converts its source data into the Sentinel Common Data Model. The transformed data undergoes rigorous quality checks before it can be used for Sentinel queries. The Sentinel Common Data Model framework, data transformation codes for several data sources, and data quality assurance packages are publicly available. Designed to run against the Sentinel Common Data Model, Sentinel's querying system comprises a suite of pre-tested, parametrizable computer programs that allow users to perform sophisticated descriptive and inferential analysis without having to exchange individual-level data across sites. Detailed documentation of capabilities of the programs as well as the codes and information required to execute them are publicly available on the Sentinel website. Sentinel also provides public trainings and online resources to facilitate use of its data model and querying system. Its study specifications conform to established reporting frameworks aimed at facilitating reproducibility and replicability of real-world data studies. Reports from Sentinel queries and associated design and analytic specifications are available for download on the Sentinel website. Sentinel is an example of how real-world data can be used to generate regulatory-grade evidence at scale using a transparent, reproducible, and replicable process.

Chinese expert consensus on diagnosis and treatment of immune checkpoint inhibitor-related skin adverse reactions (2024 edition)

Thu, 2024-05-23 06:00

Zhonghua Yi Xue Za Zhi. 2024 May 28;104(20):1790-1803. doi: 10.3760/cma.j.cn112137-20240112-00091.

ABSTRACT

Immune checkpoint inhibitors (ICIs) have emerged as crucial therapeutic agents for various malignancies by activating the host immune system against tumor cells. However, many different types of skin adverse reactions may occur during its use, including eruption, pruritus, blistering, hypopigmentation, alopecia, and even severe cases, Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN). These cutaneous immune-related adverse events (cirAEs) had a high incidence, which seriously affected patients' quality of life and antitumor treatment decisions. Some severe cutaneous adverse reactions (SCARs) even endanger patients' lives. Therefore, the Chinese Society of Dermatology, the Chinese Dermatologist Association of the Chinese Medical Doctor Association, the Dermatology Division of the Chinese Geriatrics Society, and other relevant experts jointly discussed and formulated the 'Chinese Expert Consensus on the Diagnosis and Treatment of Immune Checkpoint Inhibitor-Related Cutaneous Adverse Reactions'. This consensus covers the name, epidemiology, pathogenesis, clinical features, classification and grading of cirAEs, principles of management and the re-initiation of ICIs. It aims to provide a more scientific and authoritative reference for the diagnosis and treatment of cirAEs in China in the future.

Thu, 2024-05-23 06:00

J Yeungnam Med Sci. 2024 May 23. doi: 10.12701/jyms.2024.00213. Online ahead of print.

ABSTRACT

This case report is a unique case of solar retinopathy following antidepressant-induced mydriasis and highlights the need for comprehensive ophthalmic evaluation in patients treated with medications having mydriatic effects. A 49-year-old female patient who had received long-term antidepressant therapy presented with bilateral visual impairment after prolonged sun exposure. Fundoscopy confirmed solar retinopathy, which was attributed to drug-induced mydriasis. Medication adjustments and sun protection strategies led to full visual recovery, underscoring the importance of interdisciplinary awareness. This case emphasizes the challenges associated with the simultaneous management of psychiatric and ophthalmic conditions and highlights the need for routine ophthalmic evaluation of patients prescribed antidepressants with reported ocular side effects.

Intrathecal baclofen pump in pregnancy: case report, literature review, and management considerations

Tue, 2024-05-21 06:00

Reg Anesth Pain Med. 2024 May 20:rapm-2024-105569. doi: 10.1136/rapm-2024-105569. Online ahead of print.

ABSTRACT

BACKGROUND: Baclofen, a gamma-aminobutyric acid receptor type B agonist in the central nervous system, is the first-line medication among central nervous system modulating agents for the treatment of neurogenic muscle spasticity. While baclofen is most often administered enterally, patients with severe spasticity may be candidates for baclofen delivered by intrathecal pump. Currently, there are only nine studies reporting on the use of intrathecal baclofen (ITB) during pregnancy and childbirth.

CASE PRESENTATION: We described a female patient with a history of childhood idiopathic spasticity of the bilateral lower extremities that was controlled by ITB pump who became pregnant in her late third decade of life and delivered a healthy infant. The patient required multiple increases of her baclofen course over the course of her pregnancy.

DISCUSSION: Our case, alongside the existing literature on ITB during pregnancy, suggests that ITB therapy in pregnancy poses a low risk of teratogenicity and infant withdrawal seizures; however, larger, controlled studies are necessary to make those conclusions with confidence. Healthcare providers caring for pregnant ITB patients should be cognizant of the potential for such patients to require increased doses of ITB during pregnancy to achieve adequate symptom control.

Chondroitin sulfate-based universal nanoparticle delivers angiogenic inhibitor and paclitaxel to exhibit a combination of chemotherapy and anti-angiogenic therapy

Tue, 2024-05-21 06:00

Int J Biol Macromol. 2024 May 19:132520. doi: 10.1016/j.ijbiomac.2024.132520. Online ahead of print.

ABSTRACT

Blocking the tumor nutrient supply through angiogenic inhibitors is an effective treatment approach for malignant tumors. However, using angiogenic inhibitors alone may not be enough to achieve a significant tumor response. Therefore, we recently designed a universal drug delivery system combining chemotherapy and anti-angiogenic therapy to target tumor cells while minimizing drug-related side effects. This system (termed as PCCE) is composed of biomaterial chondroitin sulfate (CS), the anti-angiogenic peptide ES2, and paclitaxel (PTX), which collectively enhance antitumor properties. Interestingly, the PCCE system is conferred exceptional cell membrane permeability due to inherent characteristics of CS, including CD44 receptor-mediated endocytosis. The PCCE could respond to the acidic and high glutathione conditions, thereby releasing PTX and ES2. PCCE could effectively inhibit the proliferation, migration, and invasion of tumor cells and cause apoptosis, while PCCE can affect the endothelial cells tube formation and exert anti-angiogenic function. Consistently, more potent in vivo antitumor efficacy and non-toxic sides were demonstrated in B16F10 xenograft mouse models. PCCE can achieve excellent antitumor activity via modulating angiogenic and apoptosis-related factors. In summary, we have successfully developed an intelligent and responsive CS-based nanocarrier known as PCCE for delivering various antitumor drugs, offering a promising strategy for treating malignant tumors.

Antiseizure adverse drug reaction and associated factors among epileptic patients at Jimma Medical Center: a prospective observational study

Tue, 2024-05-21 06:00

Sci Rep. 2024 May 21;14(1):11592. doi: 10.1038/s41598-024-61393-9.

ABSTRACT

A growing body of evidence suggests that adverse drug reactions (ADRs) are a major cause of morbidity and mortality in the healthcare system. Fifteen to twenty-five percent of patients with epilepsy discontinued antiseizure drugs (ASDs) within 6 months of therapy owing to intolerable adverse drug reactions. In Ethiopia, the prevalence of antiseizure adverse drug reactions and associated factors was not extensively conducted in advanced settings like Jimma Medical Centers. Hence, the objective of this study is to assess patterns of adverse drug reactions and associated factors among ambulatory epileptic patients at tertiary hospitals in Ethiopia. A hospital-based prospective observational study was spanned for 1 year. Two hundred ninety patients were consecutively recruited into the study from all epileptic patients attending the ambulatory clinic. Relevant data were collected through patient interviews and medical chart reviews. The causality assessment was done by using the Naranjo Probability Scale. Epi-Data manager version 4.6.0.4 was used for data entry and statistical analysis was performed by Statistical Package for Social Science version 25.0 (SPSS). Stepwise backward logistic regression analysis was done to identify factors that increase the risk of antiseizure adverse drug reactions. The mean (± SD) age of the participants were 29.91(± 11.26) years. The overall prevalence of ADR was 33.8% (95% CI 29.2-39.9%). A total of 110 adverse drug reactions were identified among 98 patients with an average of 1.12 per patient. ADRs were frequently reported with phenobarbital (52.04%) and phenytoin (34.70%). The commonly identified adverse drug reactions were epigastric pain (27.55%) and central nervous system drowsiness (23.46%). Comorbidity (AOR = 5.91, 95% CI (2.14-16.32), seizure-free period of fewer than 2 years (AOR = 1.94, 95% CI (1.18-3.19), and polytherapy (AOR = 1.35, 95% CI (1.80-2.26) were significantly associated with adverse drug reactions. This trial had a comparatively high percentage of adverse medication reactions. Adverse medication reactions were more common in patients with polytherapy, comorbidities, and seizure-free durations less than two years. Therefore, medical practitioners should advise patients who exhibit these traits on how to reduce or avoid bad drug responses or provide comfort in the event of small incidents.

Drug-related exanthema under immunotherapy and targeted oncological therapy

Tue, 2024-05-21 06:00

Dermatologie (Heidelb). 2024 May 21. doi: 10.1007/s00105-024-05350-7. Online ahead of print.

ABSTRACT

BACKGROUND: Oncological therapies can cause a variety of mucocutaneous adverse events. Exanthematous adverse events can be challenging in the context of the urgent need for cancer treatment due to their spread, sometimes rapid progression, and mucous membrane or organ involvement.

MATERIALS AND METHODS: This article provides an overview of the most important exanthematic dermatoses as side effects of modern drug-based tumor therapies with diagnostic and therapeutic information for clinicians, taking into account the current literature and guidelines.

RESULTS: Exanthematous adverse events of immune checkpoint inhibitors, EGFR antagonists, kinase inhibitors, bispecific T‑cell engagers, and the CCR4 inhibitor mogamulizumab are reviewed in detail.

CONCLUSIONS: Cutaneous side effects are common across all drug classes and cover a broad spectrum. While some adverse events are specific to one drug class, many exanthemas can occur with both oncological immunotherapies and various targeted therapies. A reliable diagnosis, dose adjustment or discontinuation of the offending agent in consultation with the treating oncologists and appropriate symptomatic therapy are important for correct management. In the case of severe, life-threatening drug reactions, however, permanent discontinuation of the drug is essential.

Drug prescription appropriateness in hospitalized older patients: 15-year results and lessons from a countrywide register

Tue, 2024-05-21 06:00

Intern Emerg Med. 2024 May 21. doi: 10.1007/s11739-024-03645-0. Online ahead of print.

ABSTRACT

The global increase of aging with the related increase of multiple noncommunicable diseases is inevitably accompanied by the associated issue of multimorbidity and polypharmacy. The latter is not without peculiar consequences on health, because it has been shown to be associated with drug-related adverse events, mainly due to poor prescription appropriateness and drug-drug interactions. To contribute to tackle this gigantic problem, a registry of drug dispensation in hospitalized older patient has been initiated in Italy in 2008. Through the last 15 years, data on nearly 11,000 older people have been accrued during their hospital stay in internal medicine and geriatric wards. This review article summarizes the main findings obtained, and how these data contribute to tackle the issue of appropriateness of drug prescription and the need of deprescribing in hospitalized older people affected by the most common noncommunicable diseases.

Hypokalemic paralysis following intramuscular betamethasone injection: A case report and review of literature

Tue, 2024-05-21 06:00

Clin Case Rep. 2024 May 20;12(5):e8923. doi: 10.1002/ccr3.8923. eCollection 2024 May.

ABSTRACT

Acute neuromuscular paralysis is a relatively common condition in emergency rooms (ERs). They can be caused by several reasons, including adverse drug reactions. Betamethasone is a glucocorticoid commonly used for various conditions, such as allergic conditions. One of the rare but known side effects of glucocorticoids is hypokalemia. Rare cases of hypokalemia following high- and low-dose glucocorticoid injections have been reported. This study presents the history of a young, healthy male without significant past medical history who presented with an inability to stand and walk due to four-limb paralysis (more prominent in the lower limbs) following an intramuscular injection of a 4 mg betamethasone, which was prescribed for the treatment of allergic rhinitis. The patient was stabilized with an intravascular injection of potassium chloride diluted in 1000 mL of normal saline and monitored for 24 h, ruling out any other endocrine condition. Hypokalemia and its severe form are defined as the serum level of lower than 3.5 and 2.5 mEq/Lit, respectively. One of the etiologies of drug-induced hypokalemic paralysis is systemic glucocorticoid administration. In severe cases, it can cause quadriplegia and other neuromuscular, respiratory, and cardiac complications. Therefore, it is an urgent condition that should be managed carefully. Pregnant women who are receiving these medications are a specific group at risk of hypokalemic paralysis. There are several safer treatments for seasonal allergic rhinitis compared to systemic glucocorticoids, which should be considered by physicians. Moreover, paralysis in patients receiving these medications should be approached attentively since it might be caused by hypokalemia, which can be life threatening if not treated. It is advisable that the blood level of electrolytes, especially potassium, be checked for patients who present with paralysis or weakness after glucocorticoid injections.

HMMF: a hybrid multi-modal fusion framework for predicting drug side effect frequencies

Mon, 2024-05-20 06:00

BMC Bioinformatics. 2024 May 20;25(1):196. doi: 10.1186/s12859-024-05806-6.

ABSTRACT

BACKGROUND: The identification of drug side effects plays a critical role in drug repositioning and drug screening. While clinical experiments yield accurate and reliable information about drug-related side effects, they are costly and time-consuming. Computational models have emerged as a promising alternative to predict the frequency of drug-side effects. However, earlier research has primarily centered on extracting and utilizing representations of drugs, like molecular structure or interaction graphs, often neglecting the inherent biomedical semantics of drugs and side effects.

RESULTS: To address the previously mentioned issue, we introduce a hybrid multi-modal fusion framework (HMMF) for predicting drug side effect frequencies. Considering the wealth of biological and chemical semantic information related to drugs and side effects, incorporating multi-modal information offers additional, complementary semantics. HMMF utilizes various encoders to understand molecular structures, biomedical textual representations, and attribute similarities of both drugs and side effects. It then models drug-side effect interactions using both coarse and fine-grained fusion strategies, effectively integrating these multi-modal features.

CONCLUSIONS: HMMF exhibits the ability to successfully detect previously unrecognized potential side effects, demonstrating superior performance over existing state-of-the-art methods across various evaluation metrics, including root mean squared error and area under receiver operating characteristic curve, and shows remarkable performance in cold-start scenarios.
